Recently, integrative pharmacology(IP) has become a pivotal paradigm for the modernization of traditional Chinese medicines(TCM) and combinatorial drugs discovery, which is an interdisciplinary science for establishing the in vitro and in vivo correlation between absorption, distribution, metabolism, and excretion/pharmacokinetic(ADME/PK) profiles of TCM and the molecular networks of disease by the integration of the knowledge of multi-disciplinary and multi-stages. In the present study, an internet-based Computation Platform for IP of TCM(TCM-IP, www.tcmip.cn) is established to promote the development of the emerging discipline. Among them, a big data of TCM is an important resource for TCM-IP including Chinese Medicine Formula Database, Chinese Medical Herbs Database, Chemical Database of Chinese Medicine, Target Database for Disease and Symptoms, et al. Meanwhile, some data mining and bioinformatics approaches are critical technology for TCM-IP including the identification of the TCM constituents, ADME prediction, target prediction for the TCM constituents, network construction and analysis, et al. Furthermore, network beautification and individuation design are employed to meet the consumer's requirement. We firmly believe that TCM-IP is a very useful tool for the identification of active constituents of TCM and their involving potential molecular mechanism for therapeutics, which would wildly applied in quality evaluation, clinical repositioning, scientific discovery based on original thinking, prescription compatibility and new drug of TCM, et al.

Yaotongning Capsule (YTNC) is a Traditional Chinese Medicinal (TCM) formula that has been demonstrated to be effective for osteoarthritis (OA) treatment in clinical use. Many compounds and 10 component medicinal materials (CMMs for short, i.e., the fundamental elements used in TCM formulas) in YTNC are challenging to study the pharmacological effects and interactions of the CMMs. Besides, it is difficult to know whether the YTNC formula is reasonable, and if YTNC formula could be improved without comparing YTNC with other TCM formulas of treating OA. Based on different combinations of the active fractions from the 10 CMMs of YTNC and eight additional herbs frequently used in the TCM formulas of treating OA, the present study evaluated systematically the in vitro effects of these active fractions and the interactions among the active fractions from YTNC on rat chondrocytes to find possible solutions of the above questions. Based on the formulation of YTNC and the concept of combinatorial chemistry, the active fractions were applied to form the whole YTNC prescription (i.e., the combination of all YTNC active fractions and the extract of YTNC׳s vehicle), five disassembled formulas of YTNC (i.e., the combinations of some active fractions in YTNC) and 21 TCM samples consisted of different kinds of active fractions. The degenerated chondrocytes were induced with interleukin-1β (IL-1β), and then the half-effective concentration (EC50) value of the proliferation activity was analyzed to evaluate the 27 TCM samples. Nine samples were screened for the following evaluation on glycosaminoglycan (GAG) synthesis. Rat articular cartilage was obtained from six Sprague-Dawley rats (seven days of age), and then chondrocytes were isolated through enzymatic digestion with 0.2% Collagenase II. Proliferations of chondrocytes were examined through Cell Counting Kit-8 assay, when the intracellular levels of GAG were detected by 1,9-Dimethylmethylene blue staining. The interactions between the active fractions in YTNC were evaluated by comparing experimental EC50 values of the YTNC formulas with their additive EC50 values. The effects of every active fraction were estimated by comparing the EC50 values of the TCM sample containing the active fraction with that of the initial sample without the active fraction. The whole formula of YTNC was very good at promoting the proliferation and GAG synthesis among all the 27 TCM samples. The vehicle of YTNC (Chinese rice wine) strengthened the two activities of YTNC. Refer to promoting the proliferation in chondrocytes, Davallia mariesii flavonoids (not belong to YTNC) were more potent than Glycyrrhiza uralensis flavonoids in YTNC, while the saponins, volatile oils and polysaccharides of YTNC were more potent than those from the eight additional herbs. Some samples including fewer active fractions were as good as YTNC. The YTNC formula and its disassembled formulas exhibited good activities both in promoting the proliferation and GAG synthesis, and the whole formula was most potent among the six YTNC formulas. The YTNC formula is reasonable and has advantage in promoting the proliferation and GAG synthesis in IL-1β induced chondrocytes. YTNC׳s vehicle Chinese rice wine plays an important role in strengthening the activity of YTNC. YTNC may have the potential activity on treating chondrocytes degeneration caused by OA. However, the formula still can be simplified based on the combination of alkaloids, flavonoids and 50% of saponins from Glycyrrhiza uralensis to improve its quality controllability and safety. The present study can be a quite purposeful work for developing new YTNC-based formulas with maximal therapeutic efficacy and minimal adverse effects. Copyright © 2014 The Authors.

Since traditional Chinese medicine (TCM) is a complex mixture of multiple components, the application of methodologies for evaluating single-components Western medicine in TCM studies may have certain limitations. Appropriate strategies that recognize the integrality of TCM and connect to TCM theories remain to be developed. Here we use multiple unique approaches to study the scientific connotation of a TCM formula Dan-hong injection (DHI) without undermining its prescription integrity. The blood circulation improving and healing promoting effects of DHI were assessed by a qi stagnation blood stasis rat model and a mouse model of laser irradiation induced cerebral microvascular thrombosis. By UFLC-PDA-Triple Q-TOF-MS/MS and relevance analysis between chemical characters and biological effects, 82 chemical constituents and nine core components, whose blood circulation promoting effects were found comparable to that of whole DHI, were successfully identified. What’s more, the rationality of DHI prescription compatibility could be reflected not only in the maximum efficacy of the original ratio, but also in the interactions of compounds from different ingredient herbs, such as complementary activities and facilitating tissues distribution. This study provides scientific evidences in explanation of the clinical benefits of DHI, and also gives a good demonstration for the comprehensive evaluation of other TCM. PMID:28393856

Traditional Chinese medicine (TCM) has long been used for patients with psoriasis. This study aimed to investigate TCM usage in patients with psoriasis. We analyzed a cohort of one million individuals representing the 23 million enrollees randomly selected from the National Health Insurance Research Database in Taiwan. We identified 28,510 patients newly diagnosed with psoriasis between 2000 and 2010. Among them, 20,084 (70.4%) patients were TCM users. Patients who were female, younger, white-collar workers and lived in urbanized area tended to be TCM users. The median interval between the initial diagnosis of psoriasis to the first TCM consultation was 12 months. More than half (N = 11,609; 57.8%) of the TCM users received only Chinese herbal medicine. Win-qing-yin and Bai-xian-pi were the most commonly prescribed Chinese herbal formula and single herb, respectively. The core prescription pattern comprised Mu-dan-pi, Wen-qing-yin, Zi-cao, Bai-xian-pi, and Di-fu-zi. Patients preferred TCM than Western medicine consultations when they had metabolic syndrome, hepatitis, rheumatoid arthritis, alopecia areata, Crohn's disease, cancer, depression, fatty liver, chronic airway obstruction, sleep disorder, and allergic rhinitis. In conclusion, TCM use is popular among patients with psoriasis in Taiwan. Future clinical trials to investigate its efficacy are warranted. PMID:27822287

Hyperlipidemia, characterized by the abnormal blood lipid profiles, is one of the dominant factors of many chronic diseases such as diabetes, obesity, and cardiovascular diseases (CVD). For the low cost, effectiveness, and fewer side effects, the popularity of using traditional Chinese medicine (TCM) to handle hyperlipidemia is increasing and its role in health care has been recognized by the public at large. Despite the importance of TCM herbs and formulations, there is no comprehensive review summarizing their scientific findings on handling hyperlipidemia. This review summarizes the recent experimental and clinical results of nine representative single Chinese herbs and seven classic TCM formulae that could improve lipid profiles so as to help understand and compare their underlying mechanisms. Most of single herbs and formulae demonstrated the improvement of hyperlipidemic conditions with multiple and diverse mechanisms of actions similar to conventional Western drugs in spite of their mild side effects. Due to increasing popularity of TCM, more extensive, well-designed preclinical and clinical trials on the potential synergistic and adverse side effects of herb-drug interactions as well as their mechanisms are warranted. Hyperlipidemic patients should be warned about the potential risks of herb-drug interactions, particularly those taking anticoagulants and antiplatelet drugs. PMID:25110708

Over the past decades, research of traditional Chinese medicine (TCM) mainly focused on developing potential candidates from Chinese medicinal herbs, while the wisdom of applying these traditional herbs has not been paid as much attention as it deserves. As is well-known, multi-herb therapy is one of the most important characteristics of TCM, but the modernization drive of this conventional wisdom has faced many obstacles due to its unimaginable complexity. Herb pairs, the most fundamental and the simplest form of multi-herb formulae, are a centralized representative of Chinese herbal compatibility. In light of their simplicity and the basic characteristics of complex formulae, herb pairs are of great importance in the studies of herb compatibility. A systematic search of herb pair related research was carried out using multiple online literature databases, books and monographs published in the past 20 years. A comprehensive introduction to the compatibility of TCM, the position of herb pairs in TCM and the progresses of several famous herb pairs were provided in this review. Furthermore, the clinical study and the future research trends of herb pairs were also discussed. Herb pairs have played, and may continue to play a key role in full investigation of general herb compatibility for their indispensable position in TCM. Much more research is needed for the standardization, safety evaluation, and mechanism exploration of herb pairs. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Identification of bioactive components is an important area of research in traditional Chinese medicine (TCM) formula. The reported identification methods only consider the interaction between the components and the target proteins, which is not sufficient to explain the influence of TCM on the gene expression. Here, we propose the Initial Transcription Process-based Identification (ITPI) method for the discovery of bioactive components that influence transcription factors (TFs). In this method, genome-wide chip detection technology was used to identify differentially expressed genes (DEGs). The TFs of DEGs were derived from GeneCards. The components influencing the TFs were derived from STITCH. The bioactive components in the formula were identified by evaluating the molecular similarity between the components in formula and the components that influence the TF of DEGs. Using the formula of Tian-Zhu-San (TZS) as an example, the reliability and limitation of ITPI were examined and 16 bioactive components that influence TFs were identified. PMID:27034696

Traditional Chinese medicine (TCM) has become more popular as a therapy for symptom relief among menopause-aged women. The aim of this study was to analyze the utilization of TCM for climacteric women in Taiwan. The study analyzed frequency distributions among 19 379 women aged 45-55 years, recruited from a random-sampled cohort of 200 000 people from the National Health Insurance database. Data mining was conducted to explore the co-prescription patterns for finished herbal products (FHP). There were 19 379 women aged 45-55 years in the sample; of these, 12 572 (64.9%) utilized TCM services at least once. A total of 4078 (21.0%) of the 19 379 climacteric women utilized 145 200 (79.2%) TCM visits. Of these, 39 802 (21.7%) visits were because of diseases of the musculoskeletal system and connective tissue, of which more than half were treated with acupuncture and traumatology manipulative therapies. There were 28 154 visits with FHP prescriptions because of non-specific symptoms and ill-defined conditions, and Jia-wei-xiao-yao-san was the most frequent formula. Nearly two-thirds of FHP contained more than two herbal formulae. Women of climacteric age in Taiwan utilized TCM more often than other age groups. To deal with multiple symptoms and/or diseases among climacteric women, new prescription patterns of combining two or more herbal formulae have evolved. Studies on safety issues and drug-herb interactions are warranted for future research.

The identification of bioactive components in traditional Chinese medicine (TCM) is an important part of the TCM material foundation research. Recently, molecular docking technology has been extensively used for the identification of TCM bioactive components. However, target proteins that are used in molecular docking may not be the actual TCM target. For this reason, the bioactive components would likely be omitted or incorrect. To address this problem, this study proposed the GEPSI method that identified the target proteins of TCM based on the similarity of gene expression profiles. The similarity of the gene expression profiles affected by TCM and small molecular drugs was calculated. The pharmacological action of TCM may be similar to that of small molecule drugs that have a high similarity score. Indeed, the target proteins of the small molecule drugs could be considered TCM targets. Thus, we identified the bioactive components of a TCM by molecular docking and verified the reliability of this method by a literature investigation. Using the target proteins that TCM actually affected as targets, the identification of the bioactive components was more accurate. This study provides a fast and effective method for the identification of TCM bioactive components.

Background. Traditional Chinese medicine (TCM), when given as a therapy for symptom relief, has gained widespread popularity among diabetic patients. The aim of this study is to analyze the utilization of TCM among type 2 diabetic patients in Taiwan. Methods. The use of TCM for type 2 diabetic patients were evaluated using a randomly sampled cohort of 1,000,000 beneficiaries recruited from the National Health Insurance Research Database. Results. Overall, 77.9% (n = 31,289) of type 2 diabetic patients utilized TCM and 13.9% (n = 4,351) of them used TCM for the treatment of type 2 diabetes. Among the top ten most frequently prescribed herbal formulae, four remedies, Zhi-Bo-Di-Huang-Wan, Qi-Ju-Di-Huang-Wan, Ji-Sheng-Shen-Qi-Wan and Ba-Wei-Di-Huang-Wan are derivative formulae of Liu-Wei-Di-Huang-Wan. In other words, Liu-Wei-Di-Huang-Wan and its derivatives were found to be the most common herbal formulae prescribed by TCM doctors for the treatment of diabetes in Taiwan. Conclusion. Although some evidence does support the use TCM to treat diabetes, the results from the current study may have been confounded by placebo effect, which emphasize the need for well conducted, double-blind, randomized, placebo-controlled studies in order to further evaluate the efficacy of Liu-Wei-Di-Huang-Wan on patients with type 2 diabetes.

Psoriasis is a chronic inflammatory cutaneous disease characterized by clinical manifestations of erythema and white scales. The pathogenesis of psoriasis is not yet clear. Despite a combination of hormonal therapy and physiotherapy used in Western medicine, the condition often relapses after withdrawal of drugs. Traditional Chinese medicine (TCM) has therapeutic features and may be a clinically effective formula by regulating unbalanced immune systems, such as by targeting interleukins. In this paper, we review recent research about how Chinese medicine immunoregulates psoriasis via interleukins, and systematically summarizes the related mechanisms. There are three common pathways leading to psoriasis: (1) Th17 cells secrete IL-17, which is stimulated by IL-23; (2) Th1 cells secrete IL-21, TNF-[Formula: see text] and IFN-[Formula: see text], with the help of Th17 cells; (3) Th22 cells secrete IL-22 under the stimulation of Th17 cells. Clinical and experiment data indicate that TCM could modify psoriasis by antagonizing or regulating interleukin and IL-23/IL-17 axis to inhibit the main pathways.

Multiple components of traditional Chinese medicine (TCM) formulae determine their treatment targets for multiple diseases as opposed to a particular disease. However, discovering the unexplored therapeutic potential of a TCM formula remains challenging and costly. Inspired by the drug repositioning methodology, we propose an integrated strategy to feasibly identify new therapeutic uses for a formula composed of six herbs, Liuweiwuling. First, we developed a comprehensive systems approach to enrich drug compound-liver disease networks to analyse the major predicted diseases of Liuweiwuling and discover its potential effect on liver failure. The underlying mechanisms were subsequently predicted to mainly attribute to a blockade of hepatocyte apoptosis via a synergistic combination of multiple effects. Next, a classical pharmacology experiment was designed to validate the effects of Liuweiwuling on different models of fulminant liver failure induced by D-galactosamine/lipopolysaccharide (GalN/LPS) or thioacetamide (TAA). The results indicated that pretreatment with Liuweiwuling restored liver function and reduced lethality induced by GalN/LPS or TAA in a dose-dependent manner, which was partially attributable to the abrogation of hepatocyte apoptosis by multiple synergistic effects. In summary, the integrated strategy discussed in this paper may provide a new approach for the more efficient discovery of new therapeutic uses for TCM formulae.

Importance: The incidence of Bradyarrhythmias is high among the population. However, at early stages of the disease, it cannot always get enough attention and is lack of safe and effective therapies, until it is serious enough to resort to pacemaker implantation. Traditional Chinese Medicine (TCM) has a long history of treating Bradyarrhythmia, with a lot of formulas being widely used in clinical practice. While the effectiveness and the underlying mechanisms of these formulas have not yet been clearly identified. Objective: To evaluate the effectiveness of some common TCM formulas in treating patients with Bradyarrhythmia and to summarize the current evidence as to their mechanisms. Data Sources: Relevant studies were identified by searching for papers published from January 2000 to August 2017 in Pubmed; EMBASE; the Cochrane Library (Cochrane Central Register of Controlled Trials); the China National Knowledge Internet; and the China biology medicine, Wanfang, and VIP databases. The following medical subject heading (MeSH) terms were included for Pubmed search and adapted for other databases as needed-“Medicine, Chinese Traditional,” “Bradycardia.” Study Selection: Randomized clinical trials investigating treatment outcomes in Bradyarrhythmia patients with one of the six TCM formulas (Shenxian-shengmai oral liquid, Shensong Yangxin capsule, XinBao pill, Mahuang-Fuzi-Xixin decoction, Zhigancao decoction and Shengmai injection). Data Extraction and Synthesis: Two independent reviewers performed the data extraction and assessed study quality. A meta-analysis was performed to calculate risk ratio (RR) and 95% confidence index (CI) using random-effects and fixed-effects model. Results: A total of 121 clinical trials with 11138 patients were included. Of the six TCM formulas, SXSM (RR:1.33, 95% CI 1.27 to 1.39, P < 0.00001), SSYX (RR:1.52, 95% CI 1.40 to 1.66, P < 0.00001), XB can be more effective than common treatment (RR 1.18, 95% CI 1.11 to 1.26, P < 0.00001), as well as placebo (RR 5.33, 95% CI 2.88-9.87, P < 0.00001), but less effective than TCM dialectical therapy (RR:0.75, 95% CI 0.68 to 0.82, P < 0.00001). Compared to the control group, MFX (RR:1.30, 95%CI 1.23 to 1.37, P < 0.00001), ZGC (RR:1.35, 95%CI 1.23 to 1.48, P < 0.00001), SMI (RR:1.36, 95%CI 1.21 to 1.52, P < 0.00001) can be more effective. The overall quality of the included trials were relatively low, with the limitations of small sample size, inadequate descriptions in randomization, allocation concealment and blinding methods. Conclusions and Relevance: There are evidence that some TCM formulas might help to relieve Bradyarrhythmias. But with the relatively low quality of the clinical trials and mechanism studies, we still need more high-quality researches to verify the conclusions. PMID:29686614

Traditional Chinese medicine (TCM) herbal formulae can be valuable therapeutic strategies and drug discovery resources. However, the active ingredients and action mechanisms of most TCM formulae remain unclear. Therefore, the identification of potent ingredients and their actions is a major challenge in TCM research. In this study, we used a network pharmacology approach we previously developed to help determine the potential antidiabetic ingredients from the traditional Ge-Gen-Qin-Lian decoction (GGQLD) formula. We predicted the target profiles of all available GGQLD ingredients to infer the active ingredients by clustering the target profile of ingredients with FDA-approved antidiabetic drugs. We also applied network target analysis to evaluate the links between herbal ingredients and pharmacological actions to help explain the action mechanisms of GGQLD. According to the predicted results, we confirmed that a novel antidiabetic ingredient from Puerariae Lobatae radix (Ge-Gen), 4-Hydroxymephenytoin, increased the insulin secretion in RIN-5F cells and improved insulin resistance in 3T3-L1 adipocytes. The network pharmacology strategy used here provided a powerful means for identifying bioactive ingredients and mechanisms of action for TCM herbal formulae, including Ge-Gen-Qin-Lian decoction.

Patients with migraine are reportedly at increased risk of developing dementia. We aimed to investigate the association between traditional Chinese medicine (TCM) use and dementia risk in migraine patients. This longitudinal cohort study used the Taiwanese National Health Insurance Research Database to identify 32,386 diagnosed migraine patients aged 20 years and above who received treatment from 1997 to 2010. To balance comparability between TCM users and non-TCM users, we randomly selected equal numbers from each group, and compared subgroups compiled based on combinations of age, sex, index year, and year of migraine diagnosis. All enrollees received follow-up until the end of 2013 to measure dementia incidence. We identified 1,402 TCM users and non-TCM users after frequency matching. A total of 134 subjects were newly diagnosed with dementia during the follow-up period. TCM users were significantly less likely to develop dementia than non-TCM users. The most frequently prescribed formulae and single Chinese herbal products were Jia-Wei-Xiao-Yao-San and Yan-Hu-Suo, respectively. This population-based study revealed a decreased dementia risk in migraine patients with TCM use. These findings may provide a reference for dementia prevention strategies, and help integrate TCM into clinical intervention programs that provide a favorable prognosis for migraine patients.

Abstract Traditional Chinese herbal medicine (TCM) has been used in Chinese society for more than 5,000 years to treat diseases from inflammation to cancer. Here, we report the case of nine living AIDS patients in the age range of 51 to 67 who were treated with either a unique formula of TCM alone from 2001 to 2009 or the TCM from 2001 to 2006 and then switched to occasional antiretroviral therapy. Surprisingly, the viral loads of eight patients were at undetectable levels on June 28, 2016, while the remaining patient had a low viral load of 29 copies/ml. The CD4+ counts (170–592 cells/μl) and CD4+/CD8+ ratios (0.21–0.90) of the nine patients are excellent, contributing to their current good health. Thus, the case study suggests that the TCM has the potential to become a functional cure for HIV/AIDS. PMID:28067535

Background While corticosteroids and β-2 agonists are effective in managing asthma symptoms, a curative therapy for asthma is lacking. Traditional Chinese medicine (TCM), used in Asia for centuries, is beginning to play a role in Western health care as a complementary and alternative medicine (CAM) modality. There is increasing scientific evidence supporting the use of TCM for asthma treatment. Objective This review article discusses promising TCM interventions for asthma and explores their possible mechanisms of action. Methods We first reviewed five clinical studies of “anti-asthma” TCM herbal remedies published between 2005–2007. We then summarized possible mechanisms underlying their effects based on data in the original articles, published abstracts, and available data bases. Possible mechanisms include anti-inflammation, inhibition of airway smooth muscle contraction, and immunomodulation. Research on TCM herbal therapy for food allergy is rare, and we therefore focused on the effect and mechanism of action of Food Allergy Herbal Formula-2 (FAHF-2) on a murine model of peanut allergy and preliminary clinical study results. Conclusion Evidence from clinical studies supports beneficial effects of TCM herbal therapy on asthma. A number of mechanisms may be responsible for efficacy of these agents. Strong preclinical study data suggest potential efficacy of FAHF-2 for food allergy. PMID:19203653

Traditional Chinese medicine (TCM), which is the most common type of complementary and alternative medicine (CAM) used in Taiwan, is increasingly used to treat patients with breast cancer. However, large-scale studies on the patterns of TCM prescriptions for breast cancer are still lacking. The aim of this study was to determine the core treatment of TCM prescriptions used for breast cancer recorded in the Taiwan National Health Insurance Research Database. TCM visits made for breast cancer in 2008 were identified using ICD-9 codes. The prescriptions obtained at these TCM visits were evaluated using association rule mining to evaluate the combinations of Chinese herbal medicine (CHM) used to treat breast cancer patients. A total of 37,176 prescriptions were made for 4,436 outpatients with breast cancer. Association rule mining and network analysis identified Hedyotis diffusa plus Scutellaria barbata as the most common duplex medicinal (10.9%) used for the core treatment of breast cancer. Jia-Wei-Xiao-Yao-San (19.6%) and Hedyotis diffusa (41.9%) were the most commonly prescribed herbal formula (HF) and single herb (SH), respectively. Only 35% of the commonly used CHM had been studied for efficacy. More clinical trials are needed to evaluate the efficacy and safety of these CHM used to treat breast cancer. PMID:24734104

Fuzheng-Huayu formula (FZHY), a Chinese herbal mixture prescription, has been proven effective in treating liver fibrosis and cirrhosis in both clinical trials and animal experiments. In this study we assessed the metabolic mechanisms of traditional Chinese medicine (TCM) syndrome-based FZHY treatment in liver cirrhosis (LC). A total of 113 participants, including 50 healthy controls and 63 LC patients, were recruited. According to the diagnosis and differentiation of the TCM syndromes, the LC patients were classified into 5 TCM syndrome groups including the liver stagnation syndrome (LSS), spleen deficiency and damp overabundance syndrome (SDDOS), damp-heat accumulation syndrome (DHAS), liver-kidney Yin deficiency syndrome (LKYDS), and blood stagnation syndrome (BSS), and administered FZHY for 6 months. FZHY treatment significantly decreased serum levels of hyaluronic acid (HA), a biochemical marker for LC, as well as TCM syndrome scores (the TCM syndrome scores were decreased in all the groups with significant decreases in the LSS and LKYDS groups). Furthermore, FZHY treatment gradually shifted the metabolic profiles of LC patients from a pathologic state to a healthy state, especially in LC patients with LSS and LKYDS. Twenty-two differently altered metabolites (DAMs) were identified, including carbohydrates, amino acids, fatty acids, etc with 9 DAMs in LSS patients, 9 in LKYDS patients, and 4 in other patients. The metabolic pathways involved in the conversion of amino acids and the body's detoxification process were regulated first, followed by the pathways involved in the body's energy supply process. In conclusion, the evaluation of the effect of TCM syndrome-based FZHY treatment show that FZHY has a better effect on LKYDS and LSS than on the other TCM syndromes, and the metabolic mechanisms might be involved in the increased detoxification function in LKYDS and the improvement of energy supply in LSS, which provides important evidence for the clinical application of TCM syndrome-based treatment.

Peptic ulcer disease is a common digestive disease. There is a lack of large-scale survey on the use of traditional Chinese medicine (TCM) for the treatment of peptic ulcer disease. This study aimed to investigate the utilization of TCM for the treatment of peptic ulcer disease in Taiwan. We analyzed a random sample comprised of one million individuals with newly diagnosed peptic ulcer disease between 2001 and 2010 from the National Health Insurance Research Database in Taiwan. Demographic characteristics and TCM usage, including Chinese herbal formulas and the single herbs prescribed for patients with peptic ulcer disease, were analyzed. A total of 96,624 newly diagnosed subjects with peptic ulcer disease were included. 14,983 (15.5%) patients were TCM users. People residing in highly urbanized areas, younger people and female (compared with male) were more likely to use TCM. With regard to the comorbidities, TCM users had a lower prevalence of coronary artery disease, chronic obstructive lung disease, diabetes mellitus and liver cirrhosis and stroke. The average time between onset of peptic ulcer disease and the first visit to a TCM clinic was 4.7 months. Majority of the patients (n=14,449; 96.4%) received only Chinese herbal remedies. The most frequently prescribed Chinese herbal formula and single herb was Ban-Xia-Xie-Xin-Tang (Pinelliae Decoction to Drain the Epigastrium) and Hai-Piao-Xiao (Os Sepiae), respectively. The core pattern analysis showed that combination of Ban-Xia-Xie-Xin-Tang, Hai-Piao-Xiao (Os Sepiae), Yan-Hu-Suo (Rhizoma Corydalis), Bei-Mu (Bulbus Fritillariae Thunbergii) and Chuan-Lian-Zi (Fructus Toosendan) was most frequently used for peptic ulcer disease. Our study identified the core prescription patterns of TCM for patients with peptic ulcer disease in Taiwan. Further basic and clinical studies are necessary to elucidate the efficacy and mechanisms.

As a complementary medical system to Western medicine, traditional Chinese medicine (TCM) provides a unique theoretical and practical approach to the treatment of diseases over thousands of years. Confronted with the increasing popularity of TCM and the huge volume of TCM data, historically accumulated and recently obtained, there is an urgent need to explore these resources effectively by the techniques of knowledge discovery in database (KDD). This paper aims at providing an overview of recent KDD studies in TCM field. A literature search was conducted in both English and Chinese publications, and major studies of knowledge discovery in TCM (KDTCM) reported in these materials were identified. Based on an introduction to the state of the art of TCM data resources, a review of four subfields of KDTCM research was presented, including KDD for the research of Chinese medical formula, KDD for the research of Chinese herbal medicine, KDD for TCM syndrome research, and KDD for TCM clinical diagnosis. Furthermore, the current state and main problems in each subfield were summarized based on a discussion of existing studies, and future directions for each subfield were also proposed accordingly. A series of KDD methods are used in existing KDTCM researches, ranging from conventional frequent itemset mining to state of the art latent structure model. Considerable interesting discoveries are obtained by these methods, such as novel TCM paired drugs discovered by frequent itemset analysis, functional community of related genes discovered under syndrome perspective by text mining, the high proportion of toxic plants in the botanical family Ranunculaceae disclosed by statistical analysis, the association between M-cholinoceptor blocking drug and Solanaceae revealed by association rule mining, etc. It is particularly inspiring to see some studies connecting TCM with biomedicine, which provide a novel top-down view for functional genomics research. However, further developments of KDD methods are still expected to better adapt to the features of TCM. Existing studies demonstrate that KDTCM is effective in obtaining medical discoveries. However, much more work needs to be done in order to discover real diamonds from TCM domain. The usage and development of KDTCM in the future will substantially contribute to the TCM community, as well as modern life science.

Traditional Chinese medicine (TCM), when given for symptom relief, has gained widespread popularity among migraine patients. The aim of this study is to analyze the utilization of TCM among migraine patients in Taiwan. The usage, frequency of service, and the Chinese herbal products prescribed for migraine were evaluated using a representative sample of one million subjects selected at random from the 22 million beneficiaries of the National Health Insurance scheme of Taiwan. Overall, 89.3% (N=12,827) migraine patients utilized TCM and 24.2% of them sought TCM with the intention of treating their migraine-related symptoms. Migraine patients who are living in urban area and those with an episodic migraine pattern (<15 days/month) (aOR=3.18, 95% CI: 2.75-3.67) were more likely to be TCM users than those living in a rural area and those who suffered from chronic migraine (≥15 days/month) (aOR=1.00). Overall, 81.2% of TCM visits involved the prescription of a Chinese herbal remedy or remedies and Chuan-Xiong-Cha-Tiao-San, Jia-Wei-Xiao-Yao-San, Ge-Gen-Tang, Xue-Fu-Zhu-Yu-Tang, Ban-Xia-Bai-Zhu-Tian-Ma-Tang, Qing-Shang-Juan-Tong-Tang, Xiao-Chai-Hu-Tang, Tian-Ma-Gou-Teng-Yin, Bu-Zhong-Yi-Qi-Tang, and Tian-Wang-Bu-Xin-Dan were the ten most frequently prescribed formula for treating migraine based on syndrome differentiation. Chuan-Xiong-Cha-Tiao-San, which contains sedative and anti-inflammatory agents, is the most commonly prescribed Chinese herbal formula for the treatment of migraine-related phenomena.

Type 2 diabetes mellitus (T2DM) occurs in 95% of the diabetic populations. Management of T2DM is a challenge. Traditional Chinese medicines (TCM) are usually served as adjuvants used to improve diabetic syndromes in combination of routine antidiabetic drugs. For single-herb prescriptions, Ginseng, Bitter melon, Golden Thread, Fenugreek, Garlic, and Cinnamon might have antidiabetic effects in T2DM patients. Among 30 antidiabetic formulas approved by the State Food and Drugs Administrator of China, top 10 of the most frequently prescribed herbs are Membranous Milkvetch Root, Rehmannia Root, Mongolian Snakegourd Root, Ginseng, Chinese Magnoliavine Fruit, Kudzuvine Root, Dwarf Lilyturf Tuber, Common Anemarrhena Rhizome, Barbary Wolfberry Fruit, and India Bread, which mainly guided by the theory of TCM. Their action mechanisms are related to improve insulin sensitivity, stimulate insulin secretion, protect pancreatic islets, and even inhibit intake of intestinal carbohydrates. However, it is very difficult to determine antihyperglycemic components of TCM. Nevertheless, TCM are becoming popular complementary and alternative medicine in treatment of syndromes of T2DM. In the future, it requires further validation of phytochemical, pharmacological, and clinical natures of TCM in T2DM in the future studies, especially for those herbs with a high prescription frequency.

Traditional authentication method is hard to identify herb's authenticity of traditional Chinese medicine(TCM) formula granules because they have lost all their morphological characteristics. In this study, a new allele-specific PCR method was established for identifying the authentication of Jinyinhua formula granule (made from Lonicerae Japonicae Flos) based on an SNP site in trnL-trnF fragment. Genomic DNA was successfully extracted from Lonicerae Japonicae Flos and its formula granules by using an improved spin column method and then PCR was performed with the designed primer. Approximately 110 bp specific bands was obtained only in the authentic Lonicerae Japonicae Flos and its formula granules, while no bands were found in fake mixed products. In addition, the PCR product sequence was proved from Lonicerae Japonicae Flos trnL-trnF sequence by using BLAST method. Therefore, DNA molecular authentication method could make up the limitations of character identification method and microscopic identification, and quickly identify herb's authenticity of TCM formula granules, with enormous potential for market supervision and quality control.

The consistency of diagnosis made among Traditional Chinese Medicine (TCM) practitioners and the relationship between TCM diagnosis and Chinese herbal prescription have not been adequately examined. To investigate the degree of consistency with which TCM diagnoses and herbal prescriptions can be made by practitioners examining rheumatoid arthritis (RA) patients. To survey TCM diagnostic patterns and to examine the correlation between herbal prescriptions and these diagnoses for a sample of RA patients. A prospective survey. General Clinical Research Center, University of Maryland Hospital System, Baltimore, MD. Rheumatoid arthritis patients. PRACTITIONERS: Licensed acupuncturists with a minimum of 5 years licensure and education in Chinese herbs. Three TCM practitioners examined the same 39 RA patients separately, following the traditional "Four Diagnostic Methods." Patients filled out a questionnaire to serve as the data for the "Inquiry" component. They then underwent a physical examination, including the tongue and pulse, conducted by each of the practitioners. Based upon the examination results, each practitioner provided both a TCM diagnosis and a herbal prescription. These diagnoses/prescriptions were then examined with respect to the rate of agreement among the 3 practitioners. The average agreement with respect to the TCM diagnoses among the 3 pairs of TCM practitioners was 28.2% (25.6 to 33.3% with kappas ranging from 0.23 to 0.30). The degree to which the herbal prescriptions agreed with textbook recommended practice of each TCM diagnosis was 93.2% (range = 87.2 to 100%). The total agreement on TCM diagnosis on RA patients among 3 TCM practitioners was low. When less stringent, but theoretically justifiable, criteria were employed, greater consensus was obtained among the 3 practitioners. The correspondence between the TCM diagnosis and the herbal formula prescribed for that diagnosis was high, although there was little agreement among the 3 practitioners with respect to the herbal formulas prescribed for individual patients.

Increased oxidative stress induces inflammation to several tissues/organs leading to cell death and long-term injury. Traditional Chinese Medicine (TCM) with antioxidant, anti-inflammatory, anti-apoptotic, and autophagic regulatory functions has been widely used as preventive or therapeutic strategy in modern medicine. Oxidative stress and inflammation have been widely reported to contribute to cigarette smoke-induced lung inflammation, hepatotoxicity, or sympathetic activation-induced liver inflammation, lipopolysaccharide-induced renal inflammation, and substance P-mediated neurogenic hyperactive bladder based on clinical findings. In this review, we introduce several evidences for TCM treatment including Monascus adlay (MA) produced by inoculating adlay (Cois lachrymal-jobi L. var. ma-yuen Stapf) with Monascus purpureus on lung injury, Amla (Emblica officinalis Gaertn. of Euphorbiaceae family) on hepatotoxin-induced liver inflammation, Virgate Wormwood Decoction (Yīn Chén Hāo tāng) and its active component genipin on sympathetic activation–induced liver inflammation, and green tea extract and its active components, catechins, or a modified TCM formula Five Stranguries Powder (Wǔ Lén Sǎn) plus Crataegi Fructus (Shān Zhā) on hyperactive bladder. The pathophysiologic and molecular mechanisms of TCM on ameliorating inflammatory diseases are discussed in the review. PMID:24716170

Patients with vertigo are reported to exhibit a higher risk of subsequent stroke. However, it remains unclear if Traditional Chinese Medicine (TCM), the most common form of complementary and alternative medicine, can help lower the risk of stroke for these patients. So the aim of the study was to investigate the effects of TCM on stroke risk among patients with vertigo. This longitudinal cohort study used the Taiwanese National Health Insurance Research Database to identify 112,458 newly diagnosed vertigo patients aged ≥20 years who received treatment between 1998 and 2007. Among these patients, 53,203 (47.31%) received TCM after vertigo onset (TCM users), and the remaining 59,201 patients were designated as a control group (non-TCM users). All enrollees received follow-up until the end of 2012 to measure stroke incidence. Cox proportional hazards regression was used to compute the hazard ratio (HR) of stroke in recipients of TCM services. During 15-year follow-up, 5532 TCM users and 12,295 non-TCM users developed stroke, representing an incidence rate of 13.10% and 25.71% per 1000 person-years. TCM users had a significantly reduced risk of stroke compared to non-TCM users (adjusted HR=0.64; 95% confidence interval CI=0.59-0.74). The predominant effect was observed for those receiving TCM for more than 180 days (adjusted HR=0.52; 95% CI=0.49-0.56). Commonly used TCM formulae, including Ban-Xia-Bai-Zhu-Tian-Ma-Tang, Ling-Gui-Zhu-Gan-Tang, Bai Zhi (Angelica dahurica (Hoffm.) Benth. & Hook.f. ex Franch. & Sav., root), Ge Gen (Pueraria lobata (Willd.) Ohwi, root) and Hai Piao Xiao (Endoconcha Sepiae, Cuttlefish Bone) were significantly associated with lower risk of stroke. Results of this population-based study support the effects of TCM on reducing stroke risk, and may provide a reference for stroke prevention strategies. The study results may also help to integrate TCM into clinical intervention programs that provide a favorable prognosis for vertigo patients. Copyright © 2016 Elsevier Ireland Ltd.

Recently, a new syndromic disease combination theory of traditional Chinese medicine (TCM) for hypertensive treatment has been introduced. In the wake of this new concept, a new science-based TCM formula that counteracts various syndromes is needed. The objective of this study was to develop such a formula. Five of the most clinically prescribed TCM herbs that work on different syndromes, namely Gastrodia elata, Uncaria rhynchophylla, Pueraria thomsonii, Panax notoginseng, and Alisma orientale, were selected for this study. The fingerprints of these five herbs were analyzed by tri-step Fourier transform infrared spectroscopy. Three different solvents, 95% ethanol, 50% ethanol, and distilled water, were used for the maceration of the herbs and their vasodilatory effects were studied using in vitro precontracted aortic ring model. Among these, the 50% ethanolic extracts of G. elata (GE50) and A. orientale (AO50), and 95% ethanolic extracts of U. rhynchophylla (UR95), P. thomsonii (PT95), and P. notoginseng (PN95) were found to be the most effective for eliciting vasodilation. Thus, these five extracts were used for orthogonal stimulus-response compatibility group studies by using L 25 (5 5 ) formula. The best combination ratio for GE50, UR95, PT95, PN95, and AO50, which was assigned as Formula 1 (F1), was found at EC 0 , EC 25 , EC 20 , EC 20 , and EC 10 , respectively. The vasodilatory effect of the extracts prepared from different extraction methods using F1 ratio was also studied. From the results, the EC 50 and R max of total 50% ethanolic extract of five herbs using F1 ratio (F1-2) were 0.028 ± 0.005 mg/mL and 101.71% ± 3.64%, with better values than F1 (0.104 ± 0.014 mg/mL and 97.80% ± 3.12%, respectively). In conclusion, the optimum ratio and appropriate extraction method (F1-2) for the new TCM formula were revealed.

Chinese herbal products (CHPs) are commonly used in patients with hyperlipidemia in traditional Chinese medicine (TCM). Because hyperlipidemia and related disease are common issues worldwide, this study analyzed the prescription patterns and frequencies of CHPs for treating patients with hyperlipidemia in Taiwan. Traditional Chinese medicine (TCM) has become popular as a therapy for controlling symptoms in patients with hyperlipidemia. This study aimed to analyze the prescription patterns of TCM for patients with hyperlipidemia in Taiwan. The study population was recruited from a random-sampled cohort of 1,000,000 people from the National Health Insurance Research Database between 2003 and 2009. We identified 30,784 outpatient visits related with hyperlipidemia diagnosis and collected these medical records. Association rules of data mining were conducted to explore the co-prescription patterns for Chinese herbal products (CHPs). The most commonly prescribed herbal formula for hyperlipidemia treatment was Xue-Fu-Zhu-Yu-Tang (16.1%), and Shan Zha (Crataegi fructus; 25.0%) was the most commonly prescribed single herb. The most commonly prescribed combination of an herbal formula and a single herb was Xue-Fu-Zhu-Yu-Tang and Dan Shen (Radix Salviae Miltiorrhizae), and the most commonly prescribed combination of couplet herbs was Dan Shen and Shan Zha. Xue-Fu-Zhu-Yu-Tang is the most frequently prescribed formula and is typically prescribed with Shan Zha, Dan Shen, and He Shou Wu for patients with hyperlipidemia. Clinical trials are warranted in future research to investigate the effects of the CHPs in terms of safety and efficacy and in particular to evaluate potential interactions with conventional treatments.

Sheng-ma-bie-jia-tang (SMBJT) is a Traditional Chinese Medicine (TCM) formula that is widely used for the treatment of Systemic Lupus Erythematosus (SLE) in China. However, molecular mechanism behind this formula remains unknown. Here, we systematically analyzed targets of the ingredients in SMBJT to evaluate its potential molecular mechanism. First, we collected 1,267 targets from our previously published database, the Traditional Chinese Medicine Integrated Database (TCMID). Next, we conducted gene ontology and pathway enrichment analyses for these targets and determined that they were enriched in metabolism (amino acids, fatty acids, etc.) and signaling pathways (chemokines, Toll-like receptors, adipocytokines, etc.). 96 targets, which are known SLE disease proteins, were identified as essential targets and the rest 1,171 targets were defined as common targets of this formula. The essential targets directly interacted with SLE disease proteins. Besides, some common targets also had essential connections to both key targets and SLE disease proteins in enriched signaling pathway, e.g. toll-like receptor signaling pathway. We also found distinct function of essential and common targets in immune system processes. This multi-level approach to deciphering the underlying mechanism of SMBJT treatment of SLE details a new perspective that will further our understanding of TCM formulas.

To characterize the utilization of Traditional Chinese Medicine (TCM) among patients with hepatitis C (HC). This study examined datasets from the National Health Insurance Research Database in Taiwan. One cohort, including one million patients randomly sampled from the beneficiaries of the National Health Insurance Programme from January 1 to December 31 in 2010, was chosen for this analysis. People who had at least three outpatient or inpatient records and had been diagnosed with hepatitis C virus infection from 2000 to 2010 were defined as patients with HC. Patients with HC who had at least one TCM outpatient clinical record from 2000 to 2010 were defined as TCM users (N = 5,691), whereas patients with no TCM outpatient records were defined as non-TCM users (N = 2,876). The demographic data, treatment modalities and disease distributions of TCM users were analysed. Overall, 66.4 % of the patients with HC had used TCM from 2000 to 2010. Of the TCM users, 54.1 % were female. The utilization rate of TCM increased with age and peaked in the age group of those 40 - 64 years old. Herbal remedies (52.4 %) were the most commonly used agents, followed by combination therapy (46.4 %) and acupuncture alone (1.2 %). Patients who had more extrahepatic diseases and were taking more antiviral agents tended to visit TCM clinics. Jia-Wei-Xiao-Yao-San and Dan-Shen (Salvia miltiorrhiza) were the most commonly used formula and single herb, with 88,124 person-days and 59,252 person-days, respectively. Our nationwide population-based study revealed a high prevalence and specific usage patterns of TCM in patients with HC in Taiwan.

Undoubtedly, metabonomics can reveal the comprehensive efficacies of traditional Chinese medicine (TCM) formulae and its complex mechanism at the molecular biological level. In this study, an attempt was made to address the pretreatment effect of a TCM formula. In this case, as a critical point, we should first know how to really reflect the various endogenous metabolites in a disease status before a TCM formula is employed in a therapeutic procedure. Here, we explored an approach that combined high resolution LTQ-Orbitrap mass spectrometry with a spike-in method to characterize endogenous metabolites in acute myocardial ischemia (AMI) rats. As a result, 19 potential biomarkers in rat plasma were identified and 10 related disturbed pathways were perturbed in the early stages of AMI development. Subsequently, the metabonomics method was applied to investigate the pretreatment effect of the TCM formula named the Danqi Tongmai tablet (DQTM). The results revealed that the DQTM pretreatment could reduce the AMI injury and partially regulate the perturbed TCA cycle and amino and nucleotide metabolism, which were presumable related to energy metabolism and myocardial cells apoptosis/necrosis. In conclusion, UHPLC-LTQ-Orbitrap MS combined with a spike-in method were successfully applied to the metabonomics analysis of DQTM, which demonstrated that not only a comprehensive metabolic profile in the early stages of AMI development was achieved, but also that the underlying holistic efficacies were assessed and it was helpful to understand the possible mechanism of pretreatment with DQTM.

Research on core and effective formulae (CEF) does not only summarize traditional Chinese medicine (TCM) treatment experience, it also helps to reveal the underlying knowledge in the formulation of a TCM prescription. In this paper, CEF discovery from tumor clinical data is discussed. The concepts of confidence, support, and effectiveness of the CEF are defined. Genetic algorithm (GA) is applied to find the CEF from a lung cancer dataset with 595 records from 161 patients. The results had 9 CEF with positive fitness values with 15 distinct herbs. The CEF have all had relative high average confidence and support. A herb-herb network was constructed and it shows that all the herbs in CEF are core herbs. The dataset was divided into CEF group and non-CEF group. The effective proportions of former group are significantly greater than those of latter group. A Synergy index (SI) was defined to evaluate the interaction between two herbs. There were 4 pairs of herbs with high SI values to indicate the synergy between the herbs. All the results agreed with the TCM theory, which demonstrates the feasibility of our approach. PMID:24288577

Many traditional Chinese medicine (TCM) formulae have been used in cancer therapy. The JIN formula is an ancient herbal formula recorded in the classic TCM book Jin Kui Yao Lue (Golden Chamber). The JIN formula significantly delayed the growth of subcutaneous human H460 xenografted tumors in vivo compared with the growth of mock controls. Gene array analysis of signal transduction in cancer showed that the JIN formula acted on multiple targets such as the mitogen-activated protein kinase, hedgehog, and Wnt signaling pathways. The coformula treatment of JIN and diamminedichloroplatinum (DDP) affected the stress/heat shock pathway. Proteomic analysis showed 36 and 84 differentially expressed proteins between the mock and DDP groups and between the mock and JIN groups, respectively. GoMiner analysis revealed that the differentially expressed proteins between the JIN and mock groups were enriched during cellular metabolic processes, and so forth. The ones between the DDP and mock groups were enriched during protein-DNA complex assembly, and so forth. Most downregulated proteins in the JIN group were heat shock proteins (HSPs) such as HSP90AA1 and HSPA1B, which could be used as markers to monitor responses to the JIN formula therapy. The mechanism of action of the JIN formula on HSP proteins warrants further investigation. PMID:24066008

Traditional Chinese Medicine (TCM) is a style of traditional medicine informed by modern medicine but built on a foundation of more than 2500 years of Chinese medical practice. According to statistics, TCM accounts for approximately 14% of total adverse drug reaction (ADR) spontaneous reporting data in China. Because of the complexity of the components in TCM formula, which makes it essentially different from Western medicine, it is critical to determine whether ADR reports of TCM should be analyzed independently. Reports in the Chinese spontaneous reporting database between 2010 and 2011 were selected. The dataset was processed and divided into the total sample (all data) and the subsample (including TCM data only). Four different ADR signal detection methods-PRR, ROR, MHRA and IC- currently widely used in China, were applied for signal detection on the two samples. By comparison of experimental results, three of them-PRR, MHRA and IC-were chosen to do the experiment. We designed several indicators for performance evaluation such as R (recall ratio), P (precision ratio), and D (discrepancy ratio) based on the reference database and then constructed a decision tree for data classification based on such indicators. For PRR: R 1 -R 2  = 0.72%, P 1 -P 2  = 0.16% and D = 0.92%; For MHRA: R 1 -R 2  = 0.97%, P 1 -P 2  = 0.20% and D = 1.18%; For IC: R 1 -R 2  = 1.44%, P 2 -P 1  = 4.06% and D = 4.72%. The threshold of R,Pand Dis set as 2%, 2% and 3% respectively. Based on the decision tree, the results are "separation" for PRR, MHRA and IC. In order to improve the efficiency and accuracy of signal detection, we suggest that TCM data should be separated from the total sample when conducting analyses.

It is very important to rapidly discover and identify the multiple components of traditional Chinese medicine (TCM) formula. High performance liquid chromatography with high resolution tandem mass spectrometry (HPLC-HRMS/MS) has been widely used to analyze TCM formula and contains multiple-dimension data including retention time (RT), high resolution mass (HRMS), multiple-stage mass spectrometric (MS n ), and isotope intensity distribution (IID) data. So it is very necessary to exploit a useful strategy to utilize multiple-dimension data to rapidly probe structural information and identify chemical compounds. In this study, a new strategy to initiatively use the multiple-dimension LC-MS data has been developed to discover and identify unknown compounds of TCM in many styles. The strategy guarantees the fast discovery of candidate structural information and provides efficient structure clues for identification. The strategy contains four steps in sequence: (1) to discover potential compounds and obtain sub-structure information by the mass spectral tree similarity filter (MTSF) technique, based on HRMS and MS n data; (2) to classify potential compounds into known chemical classes by discriminant analysis (DA) on the basis of RT and HRMS data; (3) to hit the candidate structural information of compounds by intersection sub-structure between MTSF and DA (M,D-INSS); (4) to annotate and confirm candidate structures by IID data. This strategy allowed for the high exclusion efficiency (greater than 41%) of irrelevant ions in er-xian decoction (EXD) while providing accurate structural information of 553 potential compounds and identifying 66 candidates, therefore accelerating and simplifying the discovery and identification of unknown compounds in TCM formula.

Traditional Chinese medicine (TCM) has been widely used in China to treat various diseases for thousands of years. Given its reputed effectiveness, low cost, and favorable safety profile, TCM is attracting great interest in Western societies as a source of therapy for an array of illnesses, including allergies and asthma. Although food allergy has not been described in the TCM literature, a novel treatment for food allergy, named the food allergy herbal formula-2 (FAHF-2), was developed using TCM principles. Using a well-characterized murine model of peanut allergy, FAHF-2 has been shown to be highly effective in providing long-term protection against peanut-induced anaphylaxis, with a high safety margin. Phase 1 human trials have demonstrated the safety of FAHF-2 in food allergic individuals. Currently, a phase 2 trial examining efficacy of FAHF-2 is on-going. Other TCMs also show a potential for treating food allergies in preclinical studies. PMID:22581122

Traditional Chinese medicine (TCM) formula of Yaotongning Capsules (YTNC) is a common remedy to treat rheumatism (RA) in China and possesses diverse biological activities including anti-inflammation. However the effects of component material medicines (CMMs) in YTNC and different combinations of the CMMs on the efficacy of YTNC and the interactions of these CMMs have been being unclear due to ten CMMs and too many compounds involved in YTNC. Moreover, many TCM formulae are available for treating RA according to TCM theory. It is unknown if the YTNC prescription is better than other TCM formulae for treating RA or better efficacy could be obtained when some CMMs in YTNC are replaced by other herbs. Quantitatively investigate the in vitro effect of active fractions from the CMMs of YTNC and other eight herbs commonly used in the TCM formulae for RA treatment on anti-inflammatory activity of different combinations of the active fractions, the interactions of the active fractions to evaluate the reasonability, advantage (or disadvantage) of the YTNC prescription and to see if the prescription could be improved from the point of anti-inflammation. Twenty-six active fractions, which were categorized as alkaloids, flavonoids, saponins, volatile oils/aqueous extracts and polysaccharides were prepared to design TCM samples by combining some of the active fractions, based on the YTNC formulating principle, combination chemistry concept and the importance of the active fractions in YTNC. The anti-inflammatory activities of the samples were evaluated by their half-maximal inhibitory concentration (IC50) values that inhibiting the production of prostaglandin E2 (PGE2) in ANA-1 murine macrophages (ANA-1 cells). The cells plated in 96-well plates were classified into blank group and test sample group. Each group was stimulated with lipopolysaccharides (LPS, 1 mg/mL) for 2h. ANA-1 cells were pretreated with different concentrations of test samples prior to the addition of arachidonic acid (10 μmol/L). The supernatants were collected and measured using PGE2 ELISA Kit, and the cytotoxicity was assayed by cell counting Kit-8 (CCK8)-based test. The interactions of the active fractions in YTNC were evaluated by comparing the experimental IC50 values of the samples derived from YTNC to their corresponding additive IC50 values. The effect of each active fraction on cellular anti-inflammation-PGE2 secretion inhibition activity, and the reasonability, advantages (or disadvantages) of YTNC were evaluated based on the comparison of IC50 values of the samples. The disassembled formulae consisted of some active fractions of YTNC and the whole prescription of YTNC consisted of the all active fractions from YTNC all demonstrate cellular anti-inflammatory activity, and there were no significant differences between these formulae. The vehicle of YTNC Chinese rice wine exhibits the ability to enhance the cellular anti-inflammation of YTNC. Synergistic effect exerts in the combination of alkaloids, flavonoids and saponins of YTNC, antagonistic or additive effects occur in the other combinations of active fractions from YTNC. The anti-inflammatory activities of some TCM samples which include some active fractions from the eight selected herbs are significantly higher than the samples derived from YTNC. The flavonoids of Carthamus tinctorius, the volatile oils of Cinnamomum cassia and Angelica pubescens perform better in cellular anti-inflammation than the flavonoids and volatile oils in YTNC. The prescription of YTNC is reasonable in the view of anti-inflammation. The saponins and polysaccharides from the CMMs of YTNC have better anti-inflammatory activities than the saponins and polysaccharides from the other eight herbs. Reducing the varieties of YTNC CMMs and replacing the flavonoids and volatile oils of YTNC with the flavonoids of Carthamus tinctorius and the volatile oils of Cinnamomum cassia (or Angelica pubescens) would improve the safety and anti-inflammatory activity of YTNC. Synthetically evaluating various pharmacological activities of TCM formulae designed in the present work may lead to develop more effective and safer TCM using YTNC as prototypes.

Uterine fibroid (myoma) is one of the most common diseases in women. Although there are several studies on the efficacy of Chinese herbs, there is a lack of large-scale survey on the use of traditional Chinese medicine (TCM) for the treatment of uterine fibroid. This study aimed to investigate the utilization of Chinese herbal products for patients with uterine fibroid, prescribed by licensed TCM doctors in Taiwan. A random sample comprised of one million individuals with newly diagnosed uterine fibroid between 2002 and 2010 from the Taiwanese National Health Insurance Research Database was analyzed. Demographic characteristics, TCM usage, the frequency as well as average daily dose of Chinese herbal formulas and the single herbs prescribed for patients with uterine fibroid, were analyzed. Overall, 35,786 newly diagnosed subjects with uterine fibroid were included. Majority of these patients (87.1%; n=31,161) had visited TCM clinics. Among them, 61.8% of their visits used Chinese herbal remedies. Patients less than 45 years of age tended to use TCM more frequently than elder patients. Gui-Zhi-Fu-Ling-Wan (Cinnamon Twig and Poria Pill) was the most frequently prescribed Chinese herbal formula, while San-Leng (Rhizoma Sparganii) was the most commonly prescribed single herb. Our study identified the characteristics and prescription patterns of TCM for patients with uterine fibroid in Taiwan. Further basic mechanistic studies and clinical trials are needed to confirm the therapeutic effects and mechanisms. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Because herbal compatibility is one of the most important reasons why Traditional Chinese Medcine (TCM) formulas are effective for acquired immunodeficiency syndrome (AIDS), our study aimed to determine the compatibility of herbs based on published AIDS clinical research in Chinese periodicals. To achieve this aim, we designed a new data-mining algorithm according to TCM data characteristics. We found 25 clinical AIDS studies, all using Chinese herbs for treatment, in the Traditional Chinese Medicine Database System, and information on diagnosis and treatment was extracted. To find out herbal compatibility, especially the formulae for herbal combinations, we proposed an improved association rule algorithm based on the frequency of combinations. In this algorithm, all the compatibility relationships were displayed in a tree structure, by which the relationship between formulas and their derivation could be clearly inferred. Data analysis showed that approximately 100 herbs have been used for treating AIDS. Based on the whole herb compatibility tree, we calculated a basic formula for AIDS: Huang Qi combined with Ren Shen, Fu Ling, Bai Zhu, Bai Zhu, Dang Gui, and Bai Shao. This formula, deriving from most of clinical prescriptions, and was chosed by most of clinicians for AIDS treatment. From data mining we found that Qi replenishment and detoxification were the main treatment principles, which coincided with the AIDS pathological mechanism in which immune function is destroyed by human immunodeficiency virus (HIV). Our data-mining results suggest that the core TCM treatment of AIDS is replenishing Qi and detoxification, by which AIDS patients' immune system may be enhanced. Compatibility of Huang Qi with some frequently-used herbs have shown real efficacy in clinical practice, which warrants pharmacological research in the future.

At the molecular level, it is acknowledged that a TCM formula is often a complex system, which challenges researchers to fully understand its underlying pharmacological action. However, module detection technique developed from complex network provides new insight into systematic investigation of the mode of action of a TCM formula from the molecule perspective. We here proposed a computational approach integrating the module detection technique into a 2-class heterogeneous network (2-HN) which models the complex pharmacological system of a TCM formula. This approach takes three steps: construction of a 2-HN, identification of primary pharmacological units, and pathway analysis. We employed this approach to study Shu-feng-jie-du (SHU) formula, which aimed at discovering its molecular mechanism in defending against influenza infection. Actually, four primary pharmacological units were identified from the 2-HN for SHU formula and further analysis revealed numbers of biological pathways modulated by the four pharmacological units. 24 out of 40 enriched pathways that were ranked in top 10 corresponding to each of the four pharmacological units were found to be involved in the process of influenza infection. Therefore, this approach is capable of uncovering the mode of action underlying a TCM formula via module analysis. PMID:24376467

Abstract Pneumonia is a frequent complication in dementia patients and is associated with high mortality rates. The aim of this retrospective cohort study was to determine whether traditional Chinese medicine (TCM) therapy can decrease pneumonia risk in dementia patients. The cohort dataset was obtained from the Longitudinal Health Insurance Database 2005, a sublibrary of the National Health Insurance Research Database, containing all medical data of 1 million beneficiaries, randomly selected from the all Insurers in year 2005. Newly diagnosed dementia patients (n = 9712) without pneumonia were analyzed from January 1997 to December 2003. After matching by sex, age, urban level, Charlson comorbidity index, insured amount, and comorbidities, 1376 pairs (1:1) of TCM and non-TCM users were acquired. Every dementia patient was individually recorded from 1997 to 2012 to identify pneumonia incidence (onset after 3 months of dementia diagnosis). Demographic characteristics, Charlson comorbidity index, comorbidities, behavioral and psychological symptoms of dementia, and psychotropic drugs were also investigated. Cox proportional regression was used to compute hazard ratios and 95% confidence intervals (CIs) after adjustment for the above-mentioned variables. There were 419 (30.5%) and 762 (55.4%) pneumonia cases in the TCM and non-TCM cohorts during a mean follow-up period of 7.6 years. The adjusted hazard ratios (95% CI) for pneumonia admission was 0.62 (0.55–0.70) for the TCM group. Patients who received TCM therapy at higher cumulative doses or for longer periods experienced increased protection from pneumonia admission. Ma-Xing-Gan-Shi-Tang, Yin-Qiao-San, and Xiao-Qing-Long-Tang might represent possible formulae reducing the incidence of pneumonia. TCM might be associated with a lower risk of pneumonia in dementia patients. PMID:27631269

Certain Chinese herbal products (CHPs) may protect against the progression of heart failure (HF). However, there is a lack of research regarding the use of CHPs in patients with HF. The aims of this study were to analyze CHPs usage patterns in patients with HF and to identify the frequency and combination of CHPs most commonly used for HF. This retrospective, nationwide, population-based cohort study was conducted using a randomly sampled cohort of one million patients selected from the National Health Insurance Research Database (NHIRD) for the years 2000-2010 in Taiwan. CHP use and the top ten most frequently prescribed formulae and single herbs for treating HF were assessed, including total formulae number and average and frequency of prescriptions. Demographic characteristics, including sex and age at diagnosis of HF, were examined, together with existing comorbidities. The cohort included 19,988 newly diagnosed AD patients, who were given CHP treatment for HF between 2000 and 2010. Among them, female patients (53.3%) and those over 65years old (63.9%) were more likely to use CM. After adjusting for demographic factors, HF patients suffering from coronary artery disease (CAD) were more likely to seek traditional Chinese medicine (TCM) treatment than those with non-TCM users (57.6% vs. 52.6%). Zhi-Gan-Cao-Tang (4.07%) and Danshen (5.13%) were the most frequent formula CHP and single CHP prescribed by TCM practitioners for treating HF, respectively. Most people with HF who consumed CHPs used CHPs to supplement Yang-Qi, nourish the Ying-blood, and strengthen the heart spirit as complementary medicines to relieve HF-related symptoms, in addition to using standard anti-HF treatments. Further large-scale, randomized clinical trials are warranted in order to determine the effectiveness and safety of these herbal medicines. Copyright © 2016 Elsevier Ireland Ltd.

Constipation is a common gastrointestinal problem worldwide. The aim of this study was to determine the frequency of use and prescriptive patterns of Chinese herbal medicine (CHM) in treating constipation by analyzing the claims data of traditional Chinese medicine (TCM) from the National Health Insurance (NHI) in Taiwan. The computerized claims dataset of the TCM office visits and the corresponding prescription files in 2004 compiled by the NHI Research Institute in Taiwan were linked and processed. Visit files with the single diagnostic coding of constipation (ICD-9-CM code 564.0) were extracted to analyze the frequency and pattern of corresponding CHM prescriptions. The association rule was applied to analyze the co-prescription of CHM in treating constipation. There were 152,564 subjects who visited TCM clinics only for constipation in Taiwan during 2004 and received a total of 387,268 CHM prescriptions. Subjects between 20 and 29 years of age comprised the largest number of those treated (25.5%). Female subjects used CHM for constipation more frequently than male subjects (female:male = 3.31:1). There was an average of 4.6 items of single Chinese herbs or formula in a single prescription for constipation. Ma-zi-renwan was the most commonly prescribed herbal formula, while Da-huang (Rheum palmatum) was the most commonly used single Chinese herb. According to the association rule, the most common prescribed pattern of 2-drug combination of CHM for treating constipation was Ban-xia-xie-xin-tang plus Ma-zi-ren-wan, while the 3-drug combination of CHM was Fang-feng-tong-sheng-san, Rheum palmatum and Ma-zi-ren-wan. This study showed the pattern of single Chinese herbs or herbal formulae used in treating constipation in Taiwan. Further clinical trials are needed to evaluate the efficacy and safety of these CHMs in treating constipation. 2010 Elsevier. Published by Elsevier B.V. All rights reserved.

Oral mucositis is one of the common side effects of chemotherapy treatment with potentially severe implications. Despite several treatment approaches by conventional and complementary western medicine, the therapeutic outcome is often not satisfactory. Traditional Chinese Medicine (TCM) offers empirical herbal formulas for the treatment of oral ulceration which are used in adaptation to chemotherapy-induced mucositis. While standard concepts for TCM treatment do not exist and acceptance by conventional oncologists is still low, we conducted a review to examine the evidence of Chinese herbal treatment in oral mucositis. Eighteen relevant studies on 4 single herbs, 2 combinations of 2 herbs, and 11 multiherbal prescriptions involving 3 or more compounds were included. Corresponding molecular mechanisms were investigated. The knowledge about detailed herbal mechanisms, especially in multi-herbal prescriptions is still limited. The quality of clinical trials needs further improvement. Meta-analysis on the existent database is not possible but molecular findings on Chinese medicinal herbs indicate that further research is still promising for the treatment of chemotherapy-induced oral mucositis.

Traditional Chinese medicine (TCM) has unique therapeutic effects for complex chronic diseases. However, for the lack of an effective systematic approach, the research progress on the effective substances and pharmacological mechanism of action has been very slow. In this paper, by incorporating network biology, bioinformatics and chemoinformatics methods, an integrated approach was proposed to systematically investigate and explain the pharmacological mechanism of action and effective substances of TCM. This approach includes the following main steps: First, based on the known drug targets, network biology was used to screen out putative drug targets; Second, the molecular docking method was used to calculate whether the molecules from TCM and drug targets related to chronic kidney diseases (CKD) interact or not; Third, according to the result of molecular docking, natural product-target network, main component-target network and compound-target network were constructed; Finally, through analysis of network characteristics and literature mining, potential effective multi-components and their synergistic mechanism were putatively identified and uncovered. Bu-shen-Huo-xue formula (BSHX) which was frequently used for treating CKD, was used as the case to demonstrate reliability of our proposed approach. The results show that BSHX has the therapeutic effect by using multi-channel network regulation, such as regulating the coagulation and fibrinolytic balance, and the expression of inflammatory factors, inhibiting abnormal ECM accumulation. Tanshinone IIA, rhein, curcumin, calycosin and quercetin may be potential effective ingredients of BSHX. This research shows that the integration approach can be an effective means for discovering active substances and revealing their pharmacological mechanisms of TCM. PMID:24598793

Traditional Chinese Medicine (TCM) has been widely used as a complementary medicine in Acute Myeloid Leukemia (AML) treatment. In this study, we proposed a new classification of Chinese Medicines (CMs) by integrating the latest discoveries in disease molecular mechanisms and traditional medicine theory. We screened out a set of chemical compounds on basis of AML differential expression genes and chemical-protein interactions and then mapped them to Traditional Chinese Medicine Integrated Database. 415 CMs contain those compounds and they were categorized into 8 groups according to the Traditional Chinese Pharmacology. Pathway analysis and synthetic lethality gene pairs were applied to analyze the dissimilarity, generality and intergroup relations of different groups. We defined hub CM pairs and alternative CM groups based on the analysis result and finally proposed a formula to form an effective anti-AML prescription which combined the hub CM pairs with alternative CMs according to patients’ molecular features. Our method of formulating CMs based on patients’ stratification provides novel insights into the new usage of conventional CMs and will promote TCM modernization. PMID:28454110

Abstract With an increasing use of traditional Chinese medicine (TCM) in type 2 diabetes mellitus (T2DM), evidence of long-term benefit with adjunctive TCM treatment is limited. This study investigated whether the concurrent TCM treatment reduces the risk of vascular complications in T2DM patients by using a large population from National Health Insurance Research Database (NHIRD). We identified 33,457 adult patients with newly diagnosed T2DM using anti-diabetic agents from a random sample of one million beneficiaries in the NHIRD between January 1, 2000 and December 31, 2011. We recruited 1049 TCM users (received TCM over 30 days with a diagnosis of T2DM) and randomly selected 4092 controls as the non-TCM cohort at a ratio of 1:4 frequency-matched by age, sex, hypertension, hyperlipidemia, and index year. We investigated the prescription pattern of TCM and conducted a Cox proportional hazards regression to calculate the hazard ratios (HRs) of stroke, chronic kidney diseases (CKD), and diabetic foot between the 2 cohorts. In the TCM cohort, the prescription pattern of TCM was different between insulin and noninsulin patients. The most common herbs were Dan-Shen (Radix Salviae Miltiorrhizae) in noninsulin group and Da-Huang (Radix et Rhizoma Rhei) in insulin group. The most common formulae were Liu-Wei-Di-Huang-Wan in noninsulin group and Yu-Quan-Wan in insulin group. Although no significant reduction in the hazard ratio of CKD and diabetic foot, the incidence rate of stroke was 7.19 per 1000 person-years in the TCM cohort and 10.66 per 1000 person-years in the control cohort, respectively. After adjustment of age, sex, hypertension, hyperlipidemia, and antidiabetes agent use (including sulfonylureas, α-glucosidase, metformin, meglitinide, thiazolidinediones, and insulin), TCM cohorts were found to have a 33% decreased risk of stroke (95% CI = 0.46–0.97; P < 0.05). This population-based retrospective study showed that the complementary TCM therapy might associate with the decreased risk of stroke in T2DM, suggesting TCM as an adjunctive therapy for T2DM to prevent subsequent stroke.

Prevalence of asthma and allergy has increased over the past 2–3 decades in Westernized countries. Despite increased understanding of the pathogenesis of asthma and allergic diseases, control of severe asthma is still difficult. Asthma is also associated with high prevalence of anxiety in particular adolescents. There is no effective treatment for food allergy. Food allergy is often associated with severe and recalcitrant eczema. Novel approaches for treatment of asthma and food allergy and comorbid conditions are urgently needed. Traditional Chinese medicine (TCM), used in Asia for centuries, is beginning to play a role in Western health care. There is increasing scientific evidence supporting the use of TCM for asthma treatment. This review article discusses promising TCM interventions for asthma, food allergy and comorbid conditions and explores their possible mechanisms of action. Since 2005, several controlled clinical studies of “anti-asthma” herbal remedies have been published. Among the herbal medicines, anti-asthma herbal medicine intervention (ASHMI) is the only anti-asthma TCM product that is a US FDA investigational new drug (IND) that has entered clinical trials. Research into ASHMI’s effects and mechanisms of actions in animal models is actively being pursued. Research on TCM herbal medicines for treating food allergy is rare. The herbal intervention, Food Allergy Herbal Formula-2 (FAHF-2) is the only US FDA botanical IND under investigation as a multiple food allergy therapy. Published articles and abstracts, as well as new data generated in preclinical and clinical studies of ASHMI and FAHF-2 are the bases for this review. The effect of TCM therapy on food allergy associated recalcitrant eczema, based on case review, is also included. Laboratory and clinical studies demonstrate a beneficial effect of ASHMI treatment on asthma. The possible mechanisms underlying the efficacy are multiple. Preclinical studies demonstrated the efficacy and safety of FAHF-2 for treating food allergy in a murine model. A clinical study demonstrated that FAHF-2 is safe, well tolerated, and exhibited beneficial immunomodulatory effects. A clinical report showed that TCM treatment reduced eczema scores and improved quality of life. Herbal interventions, ASHMI and FAHF-2 may be further developed as botanical drugs for treating asthma and food allergy. TCM may also be of benefit for comorbid conditions such as anxiety and recalcitrant eczema. More controlled studies are warranted. In conclusion, novel approaches for treatment of asthma and food allergy and comorbid conditions such as anxiety and eczema are urgently needed. This article discusses promising interventions for such conditions from traditional Chinese medicine (TCM) and explores their possible mechanisms of action. PMID:21913200

The approach to investigate traditional Chinese medicine (TCM) is still in its infancy and has been facing enormous challenge. In this paper, a generally applicable strategy was developed for investigation on TCM systematically with an introduced interesting idea about a novel research system which called subchemome. A representative herb-pair, Astragali Radix-Fructus Corni, was successfully employed to expound this novel strategy. Firstly, subchemomes were prepared individually by applying the suitable column chromatography, each of them was detected by UV spectrophotometer or HPLC-DAD detector. The components in each part were then identified based on the mass spectrometric fragmentation patterns and tandem mass spectrometric data by using UHPLC-Q-TOF-MS. Using renal mesangial cell (RMC) viability assay as the evaluation of the pharmacological activity of each group, we developed the new mini herbal formulae aimed at diabetic nephropathy and identified fifteen marker components between the group of new mini herbal formulae and other groups from the angle of the constituent, and then explored the effects of new mini herbal formulae from another angle of the molecular mechanism. Overall, the presently developed strategy should be beneficial and widely used in the investigation on TCM from a new perspective. Copyright © 2016 Elsevier B.V. All rights reserved.

Traditional Chinese medicine (TCM) herbal formulae provide valuable therapeutic strategies. However, the active ingredients and mechanisms of action remain unclear for most of these formulae. Therefore, the identification of complex mechanisms is a major challenge in TCM research. This study used a network pharmacology approach to clarify the anti-inflammatory and cough suppressing mechanisms of the Chinese medicinal preparation Eriobotrya japonica - Fritillaria usuriensis dropping pills (ChuanbeiPipa dropping pills, CBPP). The chemical constituents of CBPP were identified by high-quality ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS), and anti-inflammatory ingredients were selected and analyzed using the PharmMapper and Kyoto Encyclopedia of Genes and Genomes (KEGG) bioinformatics websites to predict the target proteins and related pathways, respectively. Then, an RNA-sequencing (RNA-Seq) analysis was carried out to investigate the different expression of genes in the lung tissue of rats with chronic bronchitis. Six main constituents affected 19 predicted pathways, including ursolic acid and oleanolic acid from Eriobotrya japonica (Thunb.) Lindl. (Eri), peiminine from Fritillaria usuriensis Maxim. (Fri), platycodigenin and polygalacic acid from Platycodon grandiflorum (Jacq.) A. DC. (Pla) and guanosine from Pinellia ternata (Thunb.) Makino. (Pin). Expression of 34 genes was significantly decreased after CBPP treatment, affecting four therapeutic functions: immunoregulation, anti-inflammation, collagen formation and muscle contraction. The active components acted on the mitogen activated protein kinase (MAPK) pathway, transforming growth factor (TGF)-beta pathway, focal adhesion, tight junctions and the action cytoskeleton to exert anti-inflammatory effects, resolve phlegm, and relieve cough. This novel approach of global chemomics-integrated systems biology represents an effective and accurate strategy for the study of TCM with multiple components and multiple target mechanisms.

The Chinese medicinal herbs Radix Isatidis and Viola yedoensis Makino have been suggested to possess antiviral activity. This study tests whether these and other Chinese and Western herbal medicinal formulas can modulate the immune functions involving virus-suppression in BALB/c mouse. We first confirmed the extract from Viola yedoensis Makino, but not from Radix Isatidis, the traditional Chinese medicine (TCM) formula Chui-Uren-Chien (CUC), or a Western homeopathic medicinal drink Método Canova, could inhibit the replications of herpes simplex virus-1 and enterovirus 71 in the human neuroblastoma SK-N-SH cell line. Subsequently, the same herbal extracts and drink underwent toxicity and immunomodulatory tests on mice of 5-7 weeks old. After 8 weeks of feeding different herbal medicinal formulas, no hepatic or renal toxicity was noted in any tested animal; whereas among the immune function evaluations, only the mice treated with CUC extract were found to be associated with significant increases (p < 0.05) in both the level of plasma IgG and the percentage of monocyte in blood mononuclear cells as well as the activation of macrophage Raw264.7 cells for nitric oxide production, suggesting its role in modulating the non-specific immune response. Analyses using protein arrays showed CUC was the most potent herbal medicinal formula eliciting fluctuations in plasma cytokine and chemokine concentrations. Taking all experimental data together, we conclude Chui-Uren-Chien possesses immunomodulatory capability in mouse, but none of the herbal medicinal formulas tested here are involved in strengthening antiviral immunity.

Complementary and alternative therapies in treating atopic dermatitis are not uncommon. However, substantial evidence and consensus on treating atopic dermatitis is lacking. The aim of this study is to investigate the characteristics and utilization of traditional Chinese medicine in patients with atopic dermatitis. We retrospectively collected patients with atopic dermatitis at the Chang Gung Memorial Hospital in Taiwan between 2002 and 2011. Patients' demographic data, duration and frequency of treatment, serum total immunoglobulin E levels, and traditional Chinese medicine treatment principles and prescription were analyzed. There were 4145 patients (8.8%) received traditional Chinese medicine therapy between 2002 and 2011. Among them, 2841 (68.54%) chose TCM only and 1304 (31.46%) chose to combine TCM and WM therapies. Those who chose combination therapy were younger, and needed more times of visit and longer duration of treatment. The most frequent comorbid conditions accompany atopic dermatitis were allergic rhinitis (46.06%) and asthma (21.46%). Among the 87,573 prescriptions written for Chinese medicine, the most frequently prescribed herbal formula and single herb were Xiao-Feng-San (Eliminate Wind Powder) (16.98%) and Bai-Xian-Pi (Cortex Dictamni) (12.68%), respectively. The most commonly used therapeutic principles of herbal formulas and single herbs were releasing exterior (20.23%) and clearing heat (41.93%), respectively. Our hospital-based study characterized the utilization patterns of traditional Chinese medicine in atopic dermatitis patients. This information could be used as references for clinical application and provide valuable information for future clinical trials. Copyright © 2013 Elsevier Ltd. All rights reserved.

Through reviewing the current international market for traditional Chinese medicine (TCM), this paper identified the internationalization challenges for TCM, including unclear therapeutic material basis and mechanism, difficulty of quality control, low preparation level, registration/policy barriers, and shortage of intellectual property. To deal with these challenges, suggestions were given including: (1) product innovation of TCM (study the TCM by using the methods and means of western medicine; innovate the basic theory of TCM; develop TCM health product); (2) standard innovation of TCM; (3) building big data platform of Chinese medicine (big data platform of TCM preparation; big data platform on the quality of TCM).

With an increasing use of traditional Chinese medicine (TCM) in type 2 diabetes mellitus (T2DM), evidence of long-term benefit with adjunctive TCM treatment is limited. This study investigated whether the concurrent TCM treatment reduces the risk of vascular complications in T2DM patients by using a large population from National Health Insurance Research Database (NHIRD).We identified 33,457 adult patients with newly diagnosed T2DM using anti-diabetic agents from a random sample of one million beneficiaries in the NHIRD between January 1, 2000 and December 31, 2011. We recruited 1049 TCM users (received TCM over 30 days with a diagnosis of T2DM) and randomly selected 4092 controls as the non-TCM cohort at a ratio of 1:4 frequency-matched by age, sex, hypertension, hyperlipidemia, and index year. We investigated the prescription pattern of TCM and conducted a Cox proportional hazards regression to calculate the hazard ratios (HRs) of stroke, chronic kidney diseases (CKD), and diabetic foot between the 2 cohorts.In the TCM cohort, the prescription pattern of TCM was different between insulin and noninsulin patients. The most common herbs were Dan-Shen (Radix Salviae Miltiorrhizae) in noninsulin group and Da-Huang (Radix et Rhizoma Rhei) in insulin group. The most common formulae were Liu-Wei-Di-Huang-Wan in noninsulin group and Yu-Quan-Wan in insulin group. Although no significant reduction in the hazard ratio of CKD and diabetic foot, the incidence rate of stroke was 7.19 per 1000 person-years in the TCM cohort and 10.66 per 1000 person-years in the control cohort, respectively. After adjustment of age, sex, hypertension, hyperlipidemia, and antidiabetes agent use (including sulfonylureas, α-glucosidase, metformin, meglitinide, thiazolidinediones, and insulin), TCM cohorts were found to have a 33% decreased risk of stroke (95% CI = 0.46-0.97; P < 0.05).This population-based retrospective study showed that the complementary TCM therapy might associate with the decreased risk of stroke in T2DM, suggesting TCM as an adjunctive therapy for T2DM to prevent subsequent stroke.

Traditional Chinese medicine (TCM) is commonly provided to cancer patients, however, the patterns of prescriptions for this type of medicine in Taiwan are unclear. This study aimed to evaluate the use of traditional Chinese medicine products in colon cancer patients post-surgery in Taiwan and to research patterns of TCM. This was a cross-sectional study of newly diagnosed colon cancer patients who received surgery between 2004 and 2008 identified from the National Health Insurance Research Database of Taiwan. The prescription patterns and reasons for the use of TCM for colon cancer were analyzed. The results showed that "symptoms, signs and ill-defined conditions" (23.3%) and diseases of the digestive system (16.9%) were the most common reasons for using Chinese herbal medicine. Xiang-sha-liu-jun-zi-tang (7.1%), Bu-zhong-yi-qi-tang (4.3%), Jia-wei-xiao-yao-san (4.1%), Shen-Ling-Bai-Zhu-San (3.7%), Ban-Xia-Xie-Xin-Tang (3.4%), Gui-pi-tang (2.4%), Ping-Wei-San (2.4%), Gan-Lu-Yin (2.0%), Bao-He-Wan (1.9%), and Zhen-Ren-Huo-Ming-Yin (1.8%) were the most commonly prescribed single Chinese herbal formulae (CHF) for colon cancer patients post-surgery. Hedyotis diffusa Willd (Bai Hua She She Cao) (5.1%) and Scutellaria barbata (Ban Zhi Lian )(4.8%) were the most commonly prescribed single Chinese herbs. This study identified patterns of TCM use in colon cancer patients post-surgery in Taiwan. The herbal ingredients were most commonly used for stimulate ghrelin secretion to increase food intake and had potential anti-tumor effect. However, further research is required to evaluate any beneficial effects which could identify leads for the development of new treatment strategies using TCM. Copyright © 2014 Elsevier Ireland Ltd.

Yaotongning (YTN) is a traditional Chinese Medicine (TCM) that contains ten component medicinal materials (CMMs) and uses Chinese rice wine as a vehicle to enhance its efficacy. YTN has been used for rheumatoid arthritis (RA) treatment in China for decades and has been reported to have anti-inflammatory and analgesic effects, as well as to strengthen the immune system. The present work quantitatively evaluated the in vitro effects of active fractions from the ten CMMs that make up YTN and eight additional herbs commonly used in TCM formulas for RA treatment, as well as different combinations of these active fractions, on cellular immune response; the findings were used to determine which active fractions are responsible for promoting an immune response, and to assess whether YTN is superior to other similar formulas and whether YTN can be improved by simplifying its formula from the point of its cellular immunomodulatory activity. Using the YTN formulation principles and some concepts in combinatorial chemistry, 27 TCM samples were designed by combining some or all of the active fractions of YTN and other eight herbs used for RA treatment. Release of interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) from ANA-1 murine macrophages was measured using an enzyme-linked immunosorbent assay (ELISA). The immunoregulatory effects of the TCM samples were evaluated by comparing their half-effective concentrations (EC50) for stimulating the release of these cytokines. Among the investigated active fractions, the flavonoids from Carthamus tinctorius (Fct), Davallia mariesii (Fdm), and Cinnamomum cassia Twig volatile oils (Vca) from the eight selected herbs effectively promoted IL-1β and IL-6 release from ANA-1 cells. Saponins from the YTN CMM Glycyrrhiza uralensis (Sgu) were the most potent promoters of IL-1β and TNF-α release. The aqueous extract of YTN CMM Eupolyphaga sinensis (Ves) strongly enhanced the release of IL-1β, IL-6, and TNF-α from ANA-1 cells. The EC50 values for stimulating the secretion of IL-1β, IL-6, and TNF-α could be determined for only six samples. The full YTN formula and the sample containing 50% Glycyrrhiza uralensis saponins, 25% of the mixture of alkaloids, and 25% of the mixture of all flavonoids exhibited good comprehensive cellular immunomodulatory activity. The immunomodulatory activity of the complete YTN formula was better than that of the sample containing all active fractions of YTN without Chinese rice wine (the YTN vehicle). Sgu and Ves are the primary active fractions of YTN involved in stimulating immune responses. The YTN prescription was reasonably effective at promoting cellular immune responses. Chinese rice wine, the YTN vehicle, strengthened the immunoregulatory activity of YTN. The results of this study demonstrate that the YTN recipe could be improved by reducing the number of CMMs and altering some active fractions without reducing its activity to promote cellular immune responses.

Few studies have reported on the utilization of traditional Chinese medicine (TCM) among dementia patients. The aim of the present study is to analyze factors associated with TCM users in the dementia populations and to investigate the medical conditions related to TCM visits. A total of 18,141 dementia patients were screened from the one million sample of the National Health Insurance Research Database. The dementia patients were then divided into TCM users and non-TCM users according to their medical records between 1997 and 2008. Demographic characteristics included gender, age, insured amount, and geographic location and medical conditions including comorbidity diseases, behavioral and psychological symptoms, and anti-dementia medication were also investigated. Their tendency of TCM usage was investigated using a multivariate logistic regression. In Taiwan, 43.3% dementia patients had sought TCM treatments. The inclination of TCM usage was inversely proportional to age; the younger and early-onset dementia (age less than 55 years) patients constituted the high usage group. Female, living in central Taiwan, and higher insured amount were also associated with higher tendency of TCM use. Multilevel Poisson regression analysis showed that the Adjust odds ratios (OR) of TCM use were 1.80 (95% CI=1.68-1.94), 2.52 (95% CI=2.30-2.76), and 3.41 (95% CI=3.01-3.86) for those with one, two, three or more behavioral and psychological symptoms of dementia (BPSD), respectively compared with dementia sufferers without BPSD. In addition, polypharmacy led to higher utilization of TCM (one type: Adjust OR=1.41, 95% CI=1.28-1.56, two types: Adjust OR=1.97, 95% CI=1.63-2.00; three or more types: Adjust OR=2.95, 95% CI=2.27-2.78). More than 70% TCM visits were treated with Chinese herbal remedies, while others used acupuncture and manipulative therapies. Qi-Ju-Di-Huang-Wan (9.7%) was the most frequently prescribed formula, followed by Jia-Wei-Xiao-Yao-San and Ban-Xia-Bai-Zhu-Tian-Ma-Tang. More than 40% of the dementia patients in Taiwan used TCM. Young-onset dementia, higher number of BPSD, multiple chronic diseases, and polypharmacy were independent predictors for dementia patients seeking TCM medical advice. On the basis of the current findings, additional clinical or epidemiologic study on the prescription patterns of TCM in dementia treatment, or the herb-drug interaction and safety issue can be conducted.

Background. This study aims to share our experiences when carrying out observational studies of traditional Chinese medicine (TCM). Methods. We have proactively monitored the safety profiles of Duhuo Jisheng Tang (DJT), Suan Zao Ren Tang (SZRT), and TMN-1. A list of adverse events (AEs), complete blood counts, and liver and kidney function tests were obtained from the participants during their scheduled hospital visits. Retrospective observational studies were conducted based on the reimbursement database of the National Health Insurance system, Taiwan, to explore the relationship between the use of TCM that have been adulterated by aristolochic acid and the risk from both nephrotoxins and carcinogens. Results. A total of 221, 287, and 203 AEs were detected after SZRT, DJT, and TMN-1 had been taken, respectively. Dizziness, headache, stomach ache, and diarrhea were judged to be probably related to SZRT treatment. Retrospective observational studies found an association between the consumption of aristolochic acid-containing Chinese formulae such as Mu Tong and an increased risk of CKD, ESRD, and urinary tract cancer. Conclusion. Prospective and retrospective observational studies seem to have specific advantages when investigating the safety and adverse effects of TCM therapies, as well as possibly other alternative/complementary therapies.

2015-01-01

The wide-reaching distributed angiosperm family Ranunculaceae has approximately 2200 species in around 60 genera. Chemical components of this family include several representative groups: benzylisoquinoline alkaloid (BIA), ranunculin, triterpenoid saponin and diterpene alkaloid, etc. Their extensive clinical utility has been validated by traditional uses of thousands of years and current evidence-based medicine studies. Drug metabolism and pharmacokinetic (DMPK) studies of plant-based natural products are an indispensable part of comprehensive medicinal plant exploration, which could facilitate conservation and sustainable utilization of Ranunculaceae pharmaceutical resources, as well as new chemical entity development with improved DMPK parameters. However, DMPK characteristics of Ranunculaceaederived medicinal compounds have not been summarized. Black cohosh (Cimicifuga) and goldenseal (Hydrastis) raise concerns of herbdrug interaction. DMPK studies of other Ranunculaceae genera, e.g., Nigella, Delphinium, Aconitum, Trollius, and Coptis, are also rapidly increasing and becoming more and more clinically relevant. In this contribution, we highlight the up-to-date awareness, as well as the challenges around the DMPK-related issues in optimization of drug development and clinical practice of Ranunculaceae compounds. Herb-herb interaction of Ranunculaceae herb-containing traditional Chinese medicine (TCM) formula could significantly influence the in vivo pharmacokinetic behavior of compounds thereof, which may partially explain the complicated therapeutic mechanism of TCM formula. Although progress has been made on revealing the absorption, distribution, metabolism, excretion and toxicity (ADME/T) of Ranunculaceae compounds, there is a lack of DMPK studies of traditional medicinal genera Aquilegia, Thalictrum and Clematis. Fluorescent probe compounds could be promising substrate, inhibitor and/or inducer in future DMPK studies of Ranunculaceae compounds. A better understanding of the important herb-drug/herb-herb interactions, bioavailability and metabolomics aspects of Ranunculaceae compounds will bolster future natural product-based drug design and the comprehensive investigation of inter-individual inconsistency of drug metabolism.

Recently, the pharmaceutical industry has shifted to pursuing combination therapies that comprise more than one active ingredient. Interestingly, combination therapies have been used for more than 2500 years in traditional Chinese medicine (TCM). Understanding optimal proportions and synergistic mechanisms of multi-component drugs are critical for developing novel strategies to combat complex diseases. A new multi-objective optimization algorithm based on least angle regression-partial least squares was proposed to construct the predictive model to evaluate the synergistic effect of the three components of a novel combination drug Yi-qi-jie-du formula (YJ), which came from clinical TCM prescription for the treatment of encephalopathy. Optimal proportion of the three components, ginsenosides (G), berberine (B) and jasminoidin (J) was determined via particle swarm optimum. Furthermore, the combination mechanisms were interpreted using PLS VIP and principal components analysis. The results showed that YJ had optimal proportion 3(G): 2(B): 0.5(J), and it yielded synergy in the treatment of rats impaired by middle cerebral artery occlusion induced focal cerebral ischemia. YJ with optimal proportion had good pharmacological effects on acute ischemic stroke. The mechanisms study demonstrated that the combination of G, B and J could exhibit the strongest synergistic effect. J might play an indispensable role in the formula, especially when combined with B for the acute stage of stroke. All these data in this study suggested that in the treatment of acute ischemic stroke, besides restoring blood supply and protecting easily damaged cells in the area of the ischemic penumbra as early as possible, we should pay more attention to the removal of the toxic metabolites at the same time. Mathematical system modeling may be an essential tool for the analysis of the complex pharmacological effects of multi-component drug. The powerful mathematical analysis method could greatly improve the efficiency in finding new combination drug from TCM. PMID:24236065

The safety of traditional Chinese medicine (TCM) is a major strategic issue that involves human health. With the continuous improvement in disease prevention and treatment, the export of TCM and its related products has increased dramatically in China. However, the frequent safety issues of Chinese medicine have become the ‘bottleneck’ impeding the modernization of TCM. It was proved that mycotoxins seriously affect TCM safety; the pesticide residues of TCM are a key problem in TCM international trade; adulterants have also been detected, which is related to market circulation. These three factors have greatly affected TCM safety. In this study, fast, highly effective, economically-feasible and accurate detection methods concerning TCM safety issues were reviewed, especially on the authenticity, mycotoxins and pesticide residues of medicinal materials.

With the current trend of globalization, unprecedented opportunities and enormous changes have emerged for the global development of traditional Chinese medicine (TCM). However, many old and new challenges and problems still remain, including partial or limited comprehension of acupuncture, oriental medicine and TCM, the existence of non-standardized institutes of TCM and acupuncture training schools, unqualified TCM practitioners, and problems concerning Chinese herbal medicine and inexperience in conducting TCM business. These problems will doubtlessly impede the further development of TCM worldwide in the foreseeable future. It is also clear that the globalization of TCM will require a large scale systematic project and constitute an arduous historical task. This paper aims to consolidate 6 strategic development modes to reinforce and facilitate the process of TCM globalization through a detailed analysis of both the present status and existing problems concerning the development of TCM in the United States.

The quest for modernisation of traditional Chinese medicine

PubMed Central

2013-01-01

Traditional Chinese medicine (TCM) is an integral part of mainstream medicine in China. Due to its worldwide use, potential impact on healthcare and opportunities for new drug development, TCM is also of great international interest. Recently, a new era for modernisation of TCM was launched with the successful completion of the Good Practice in Traditional Chinese Medicine Research in the Post-genomic Era (GP-TCM) project, the European Union’s Seventh Framework Programme (FP7) coordination action on TCM research. This 3.5-year project that involved inputs from over 200 scientists resulted in the production of 20 editorials and in-depth reviews on different aspects of TCM that were published in a special issue of Journal of Ethnopharmacology (2012; volume 140, issue 3). In this narrative review, we aim to summarise the findings of the FP7 GP-TCM project and highlight the relevance of TCM to modern medicine within a historical and international context. Advances in TCM research since the 1950s can be characterised into three phases: Phase I (1950s-1970s) was fundamental for developing TCM higher education, research and hospital networks in China; Phase II (1980s-2000s) was critical for developing legal, economic and scientific foundations and international networks for TCM; and Phase III (2011 onwards) is concentrating on consolidating the scientific basis and clinical practice of TCM through interdisciplinary, interregional and intersectoral collaborations. Taking into account the quality and safety requirements newly imposed by a globalised market, we especially highlight the scientific evidence behind TCM, update the most important milestones and pitfalls, and propose integrity, integration and innovation as key principles for further modernisation of TCM. These principles will serve as foundations for further research and development of TCM, and for its future integration into tomorrow’s medicine. PMID:23763836

Usefulness of traditionally defined herbal properties for distinguishing prescriptions of traditional Chinese medicine from non-prescription recipes.

2007-01-03

Traditional Chinese medicine (TCM) has been widely practiced and is considered as an attractive to conventional medicine. Multi-herb recipes have been routinely used in TCM. These have been formulated by using TCM-defined herbal properties (TCM-HPs), the scientific basis of which is unclear. The usefulness of TCM-HPs was evaluated by analyzing the distribution pattern of TCM-HPs of the constituent herbs in 1161 classical TCM prescriptions, which shows patterns of multi-herb correlation. Two artificial intelligence (AI) methods were used to examine whether TCM-HPs are capable of distinguishing TCM prescriptions from non-TCM recipes. Two AI systems were trained and tested by using 1161 TCM prescriptions, 11,202 non-TCM recipes, and two separate evaluation methods. These systems correctly classified 83.1-97.3% of the TCM prescriptions, 90.8-92.3% of the non-TCM recipes. These results suggest that TCM-HPs are capable of separating TCM prescriptions from non-TCM recipes, which are useful for formulating TCM prescriptions and consistent with the expected correlation between TCM-HPs and the physicochemical properties of herbal ingredients responsible for producing the collective pharmacological and other effects of specific TCM prescriptions.

By using the traditional Chinese medicine inheritance support system (TCMISS) in this study, the prescription rules of Baizhi formulae were analyzed and the core herbal pair "Baizhi-Chuanxiong" was obtained. Through the systemic analysis of prescription rules of "Baizhi-Chuanxiong" and combined with the pharmacology thinking of "Baizhi-Chuanxiong" in treating headache, the paper was aimed to find out the combination rules containing Baizhi andits molecular mechanisms for treating headaches, and provide the theory basis for further research and reference of Baizhi and its formula. Totally 3 887 prescriptions were included in this study, involving 2 534 Chinese herbs. With a support degree of 20% in analysis, 16 most commonly used drug combinations were screened, which were mainly used to treat 15 types of diseases. Baizhi was often used to treat headache, and the core combination "Baizhi-Chuanxiong" was also often used to treat, consistent with ancient record. A chemical database was established; then the headache and migraine disease targets were retrieved and added in the database to build up the "compounds-targets-pathways "core network of "Baizhi-Chuanxiong" by the internet-based computation platform for IP of TCM (TCM-IP). TCM-IP was then applied to study the molecular mechanism of "Baizhi-Chuanxiong" treatment of headache. The results suggested that37 chemical compounds in the core combination "Baizhi-Chuanxiong" were closely related with headache treatment by adjusting serotonin levels or applying to inflammation-related targets and energy metabolism pathways such as purine metabolism, pyruvate metabolism, fatty acid degradation, carbon metabolism and gluconeogenesis.

The aim of this study is to understand the current tradition and complementary medicine (T&CM) education in Malaysia. We referred to literature regarding to traditional medicine education in Malaysia, and collected the information via website or interview with faculty of T&CM in universities/colleges and Division of T&CM, Ministry of Health, Malaysia. T&CM education in Malaysia has been following China’s T&CM systems for 50 years. Currently, Division of T&CM, Ministry of Health; and Ministry of Higher Education has approved 11 institutions to offer T&CM education. Students may major in Chinese herbal medicine, acupuncture, or other T&CM subjects. Generally, clinical training programs in China, Taiwan, or Australia include substantial proportion of clinical training. We report on the general information of T&CM education in Malaysia. This result would be the first-stage information for the establishment of a strategy regarding the enhancement of T&CM education in Malaysia. PMID:28853309

Traditional Chinese medicine (TCM) investigates the clinical diagnosis and treatment regularities in a typical schema of personalized medicine, which means that individualized patients with same diseases would obtain distinct diagnosis and optimal treatment from different TCM physicians. This principle has been recognized and adhered by TCM clinical practitioners for thousands of years. However, the underlying mechanisms of TCM personalized medicine are not fully investigated so far and remained unknown. This paper discusses framework of TCM personalized medicine in classic literatures and in real-world clinical settings, and investigates the underlying mechanisms of TCM personalized medicine from the perspectives of network medicine. Based on 246 well-designed outpatient records on insomnia, by evaluating the personal biases of manifestation observation and preferences of herb prescriptions, we noted significant similarities between each herb prescriptions and symptom similarities between each encounters. To investigate the underlying mechanisms of TCM personalized medicine, we constructed a clinical phenotype network (CPN), in which the clinical phenotype entities like symptoms and diagnoses are presented as nodes and the correlation between these entities as links. This CPN is used to investigate the promiscuous boundary of syndromes and the co-occurrence of symptoms. The small-world topological characteristics are noted in the CPN with high clustering structures, which provide insight on the rationality of TCM personalized diagnosis and treatment. The investigation on this network would help us to gain understanding on the underlying mechanism of TCM personalized medicine and would propose a new perspective for the refinement of the TCM individualized clinical skills.

[Inheritance on and innovation of traditional Chinese medicine (TCM) flavor theory and TCM flavor standardization principle flavor theory in Compendium of Materia Medica].

All previous literatures about Chinese herbal medicines show distinctive traditional Chinese medicine (TCM) flavors. Compendium of Materia Medica is an influential book in TCM history. The TCM flavor theory and flavor standardization principle in this book has important significance for modern TCM flavor standardization. Compendium of Materia Medica pays attention to the flavor theory, explain the relations between the flavor of medicine and its therapeutic effects by means of Neo-Confucianism of the Song and Ming Dynasties. However,the book has not reflected and further developed the systemic theory, which originated in the Jin and Yuan dynasty. In Compendium of Materia Medica , flavor are standardized just by tasting medicines, instead of deducing flavors. Therefore, medicine tasting should be adopted as the major method to standardize the flavor of medicine.

Traditional Chinese medication (TCM) has analgesic and anti-inflammatory effects in patients with knee osteoarthritis (OA). We conducted the first systematic review of the best quantitative and qualitative evidence currently available in order to evaluate the effectiveness of TCM in relieving pain in knee OA. A comprehensive literature search was conducted using three English and four Chinese biomedical databases from their inception through March 1, 2015. We included randomized controlled trials of TCM for knee OA with intervention durations of at least two weeks. The effects of TCM on pain and other clinical symptoms were measured with the visual analog scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The total effectiveness rate, which was used to assess overall pain, physical performance and wellness, was also measured. Two researchers independently extracted data on study design, population characteristics, duration, intervention, outcomes, risk of bias, and primary results. We performed a random-effects meta-analysis when appropriate. We also explored factors that could explain the heterogeneity by conducting subgroup and meta-regression analyses. Twenty-three studies, totaling 2362 subjects, met the eligibility criteria. Treatments were formulated with an average of 8 Chinese herbs and were prescribed based on the traditional Chinese diagnostic method of syndrome differentiation. The mean treatment duration was seven weeks, with oral administration occurring one to three times a day. Compared with non-steroidal anti-inflammatory drugs and intra-articular hyaluronate injections, 18 of the studies showed significantly improved VAS pain scores (Mean Difference [MD] [Formula: see text] 0.56; 95% confidence interval [CI], 0.18 to 0.94; [Formula: see text]), six of the studies showed significantly improved WOMAC pain subscale scores (MD [Formula: see text] 2.23; 95% CI, 0.56 to 3.91; [Formula: see text]), and 16 of the trials showed significantly improved total effectiveness rates (risk ratio [Formula: see text] 1.12; 95% CI, 1.05 to 1.19; [Formula: see text] 0.0003). In addition, TCM showed a lower risk of adverse events than standard western treatments. This evidence suggests that TCM is safe and effective for improving pain, function, and wellness in treatments of knee OA. However, there is inherent clinical heterogeneity (diverse TCM formulations, controls, and treatment regimens) among the included trials. Despite these limitations, the potential analgesic effects of TCM warrant further methodologically rigorous research to determine the clinical implications of TCM on pain management in knee OA.

Nano traditional Chinese medicine (nano TCM) refers to bioactive ingredients, bioactive parts, medicinal materials or complex prescription, being approximately 100 nm in size, which are processed by nanotechnology. Nano TCM is a product of the TCM modernization, and is an application of nanotechnology in the field of TCM. This article reviews literatures on researches of nano TCM, which were published in the past 15 years. Different nanotechnologies have been used in preparation of Nano TCM in view of the varying aims of the study. The mechanical crushing technology is the main approach for nanolization of TCM material and complex prescription, and nanoparticulate drug delivery systems is the main approach for nanolization of bioactive ingredients or bioactive parts in TCM. Nano TCM has a number of advantages, for example, enhancing the bioavailability of TCM, reducing the adverse effects of TCM, achieving sustained release, attaining targeted delivery, enhancing pharmacological effects and improving the administration route of TCM. However, there are still many problems that must be resolved in nano TCM research. The main challenges to nano TCM include the theory system of TCM modernization, preparation technology, safety and stability, etc.

High fructose diet-induced metabolic syndrome: Pathophysiological mechanism and treatment by traditional Chinese medicine.

PubMed

Pan, Ying; Kong, Ling-Dong

2018-04-01

Fructose is a natural monosaccharide broadly used in modern society. Over the past few decades, epidemiological studies have demonstrated that high fructose intake is an etiological factor of metabolic syndrome (MetS). This review highlights research advances on fructose-induced MetS, especially the underlying pathophysiological mechanism as well as pharmacotherapy by traditional Chinese medicine (TCM), using the PubMed, Web of science, China National Knowledge Infrastructure, China Science and Technology Journal and Wanfang Data. This review focuses on de novo lipogenesis (DNL) and uric acid (UA) production, two unique features of fructolysis different from glucose glycolysis. High level of DNL and UA production can result in insulin resistance, the key pathological event in developing MetS, mostly through oxidative stress and inflammation. Some other pathologies like the disturbance in brain and gut microbiota in the development of fructose-induced MetS in the past years, are also discussed. In management of MetS, TCM is an excellent representative in alternative and complementary medicine with a complete theory system and substantial herbal remedies. TCMs against MetS or MetS components, including Chinese patent medicines, TCM compound formulas, single TCM herbs and active compounds of TCM herbs, are reviewed on their effects and molecular mechanisms. TCMs with hypouricemic activity, which specially target fructose-induced MetS, are highlighted. And new technologies and strategies (such as high-throughput assay and systems biology) in this field are further discussed. In summary, fructose-induced MetS is a multifactorial disorder with the underlying complex mechanisms. Current clinical and pre-clinical evidence supports the potential of TCMs in management of MetS. Additionally, TCMs may show some advantages against complex MetS as their holistic feature through multiple target actions. However, further work is needed to confirm the effectivity and safety of TCMs by high-standard clinical trials, clarify the molecular mechanisms, and develop new anti-MetS drugs by development and application of optimized and feasible strategies and methods.

Objective Combinations of Chinese herbal products (CHPs) are widely used for ischemic heart disease (IHD) in Taiwan. We analyzed the usage and frequency of CHPs prescribed for patients with IHD. Methods A nationwide population-based cross-sectional study was conducted, 53531 patients from a random sample of one million in the National Health Insurance Research Database (NHIRD) from 2000 to 2010 were enrolled. Descriptive statistics, the multiple logistic regression method and Poisson regression analysis were employed to estimate the adjusted odds ratios (aORs) and adjusted risk ratios (aRRs) for utilization of CHPs. Results The mean age of traditional Chinese medicine (TCM) nonusers was significantly higher than that of TCM users. Zhi-Gan-Cao-Tang (24.85%) was the most commonly prescribed formula CHPs, followed by Xue-Fu-Zhu-Yu-Tang (16.53%) and Sheng-Mai-San (16.00%). The most commonly prescribed single CHPs were Dan Shen (29.30%), Yu Jin (7.44%), and Ge Gen (6.03%). After multivariate adjustment, patients with IHD younger than 29 years had 2.62 times higher odds to use TCM than those 60 years or older. Residents living in Central Taiwan, having hyperlipidemia or cardiac dysrhythmias also have higher odds to use TCM. On the contrary, those who were males, who had diabetes mellitus (DM), hypertension, stroke, myocardial infarction (MI) were less likely to use TCM. Conclusions Zhi-Gan-Cao-Tang and Dan Shen are the most commonly prescribed CHPs for IHD in Taiwan. Our results should be taken into account by physicians when devising individualized therapy for IHD. Further large-scale, randomized clinical trials are warranted in order to determine the effectiveness and safety of these herbal medicines. PMID:26322893

This study aims to examine resources and utilization of traditional Chinese medicine (TCM) and factors influencing TCM utilization in urban community health centers (CHCs) in Hubei Province of China. A cross-sectional survey including 234 government-owned CHCs was conducted in 2009. One-way analysis of variance analysis and a Poisson regression model were used to examine distribution of TCM resources and factors influencing TCM utilization. This study found unequal distribution of TCM resources among districts. TCM outpatient visits were positively associated with higher economic development districts, lower initial capital investment of the CHCs, health services covered by health insurance, higher qualification of TCM physicians, provision of TCM health records and rehabilitation, and greater availability of herbal medicine. To achieve equal access to TCM services, policy makers should consider the socioeconomic differences and income groups, provide training for TCM physicians, build pathway to recruit senior TCM physicians, and cover more TCM therapies by health insurance. © 2013 APJPH.

Chinese herbal products (CHPs) have been frequently used among patients with chronic diseases including hypertension; however, the co-prescription pattern of herbal formulae and single herbs remain uncharacterized. Thus, this large-scale pharmacoepidemiological study evaluated the frequency and co-prescription pattern of CHPs for treating hypertension in Taiwan from 2003 to 2009. The database of traditional Chinese medicine (TCM) outpatient claims was obtained from the National Health Insurance in Taiwan. Patients with hypertension during study period were defined according to diagnostic codes in the International Classification of Disease Ninth Revision, Clinical Modification. The frequencies and percentages of herbal formula and single herb prescriptions for hypertension were analyzed. We also applied association rules to evaluate the CHPs co-prescription patterns. The hypertension cohort included 154,083 patients, 123,240 patients of which (approximately 80 %) had used TCM at least once. In total, 81,582 visits involving CHP prescriptions were hypertension related; Tian-Ma-Gou-Teng-Yin and Dan Shen (Radix Salvia Miltiorrhizae) were the most frequently prescribed herbal formula and single herb, respectively, for treating hypertension. This study elucidated the utilization pattern of CHPs for treating hypertension. Future studies on the efficacy and safety of these CHPs and on drug-herb interactions are warranted.

Model Organisms and Traditional Chinese Medicine Syndrome Models

Traditional Chinese medicine (TCM) is an ancient medical system with a unique cultural background. Nowadays, more and more Western countries due to its therapeutic efficacy are accepting it. However, safety and clear pharmacological action mechanisms of TCM are still uncertain. Due to the potential application of TCM in healthcare, it is necessary to construct a scientific evaluation system with TCM characteristics and benchmark the difference from the standard of Western medicine. Model organisms have played an important role in the understanding of basic biological processes. It is easier to be studied in certain research aspects and to obtain the information of other species. Despite the controversy over suitable syndrome animal model under TCM theoretical guide, it is unquestionable that many model organisms should be used in the studies of TCM modernization, which will bring modern scientific standards into mysterious ancient Chinese medicine. In this review, we aim to summarize the utilization of model organisms in the construction of TCM syndrome model and highlight the relevance of modern medicine with TCM syndrome animal model. It will serve as the foundation for further research of model organisms and for its application in TCM syndrome model. PMID:24381636

Metabolomics provides an opportunity to develop the systematic analysis of the metabolites and has been applied to discovering biomarkers and perturbed pathways which can clarify the action mechanism of traditional Chinese medicines (TCM). TCM is a comprehensive system of medical practice that has been used to diagnose, treat and prevent illnesses more than 3000 years. Metabolomics represents a powerful approach that provides a dynamic picture of the phenotype of biosystems through the study of endogenous metabolites, and its methods resemble those of TCM. Recently, metabolomics tools have been used for facilitating interactional effects of both Western medicine and TCM. We describe a protocol for investigating how metabolomics can be used to open up 'dialogue' between Chinese and Western medicine, and facilitate lead compound discovery and development from TCM. Metabolomics will bridge the cultural gap between TCM and Western medicine and improve development of integrative medicine, and maximally benefiting the human.

Antiinflammatory and Hepatoprotective Medicinal Herbs as Potential Substitutes for Bear Bile.

PubMed

Appiah, Sandra; Revitt, Mike; Jones, Huw; Vu, Milan; Simmonds, Monique; Bell, Celia

2017-01-01

Practitioners of traditional Chinese medicine (TCM) commonly prescribe medicinal formulations relying on the purported synergism of a combination of plant species, sometimes incorporating animal parts and minerals. Bear bile, obtained from either wild or farmed bears, is a commonly used constituent of traditional medicine formulations. With several bear species now listed under Convention on International Trade in Endangered Species of Wild Fauna and Flora as threatened with extinction and with bear farming being actively campaigned against on ethical grounds, it is important to seek and promote alternatives to the use of bear bile as medicine. This chapter describes and evaluates the scientific data relating to the efficacy of bear bile and potential alternatives to its use, including the use of bile from other animal species, the use of synthetic chemical alternatives, and the use of herbal substitutes. Scientific studies have confirmed the efficacy of bear bile as an antiinflammatory and a hepatoprotective agent. Ursodeoxycholic acid (UDCA), the active component of bear bile is used in a synthetic form in Western medicine and can serve as an alternative to bear bile in the treatment and management of certain cholestatic liver conditions. In TCM practice, bile from domesticated animal species (such as cattle, chicken, and pig) has been used as a substitute for bear bile. Following evaluation of TCM literature and pharmacological/clinical data, the authors propose six plant species, either as single herbs or in combination, Gardenia jasminoides (zhī zi; ), Scutellaria baicalensis (huáng qín; ), Coptis chinensis (huáng lián, ), Phellodendron amurense (huáng băi; ), Andrographis paniculata (chuan xin lian; ), and Rheum palmatum (dà huang; ), two medicinal Kampo formulations, Orengedokuto, Dia-Orengedokuto (which originated from traditional Chinese herbal formula Huanglian Jiedu Tang, ), and two individual phytochemicals (berberine and andrographolide) as alternatives to bear bile. The proposed herbal alternatives are frequently found listed in traditional formulations also containing bear bile, usually with different therapeutic roles ascribed to them. The existing evidence base for the effectiveness of herbal alternatives is sufficiently strong for TCM practitioners and consumers to consider using these without the addition of bear bile. This consideration is driven by the imperative to protect populations of bears from overexploitation in the wild and when farmed. However, for the identified alternatives to be accepted by users, it is essential that researchers and TCM practitioners collaborate effectively to initiate consumer behavior change. © 2017 Elsevier Inc.

Positive evidence from clinical trials has fueled growing acceptance of traditional Chinese medicine (TCM) for the treatment of cardiac diseases; however, little is known about the underlying mechanisms. Here, we investigated the nature and underlying mechanisms of the effects of YiXin-Shu (YXS), an antioxidant-enriched TCM formula, on myocardial ischemia/reperfusion (MI/R) injury. YXS pretreatment significantly reduced infarct size and improved viable myocardium metabolism and cardiac function in hypercholesterolemic mice. Mechanistically, YXS attenuated myocardial apoptosis by inhibiting the mitochondrial mediated apoptosis pathway (as reflected by inhibition of mitochondrial swelling, cytochrome c release and caspase-9 activity, and normalization of Bcl-2 and Bax levels) without altering the death receptor and endoplasmic reticulum-stress death pathways. Moreover, YXS reduced oxidative/nitrative stress (as reflected by decreased superoxide and nitrotyrosine content and normalized pro- and anti-oxidant enzyme levels). Interestingly, YXS upregulated endogenous nuclear receptors including LXRα, PPARα, PPARβ and ERα, and in-vivo knockdown of cardiac-specific LXRα significantly blunted the cardio-protective effects of YXS. Collectively, these data show that YXS is effective in mitigating MI/R injury by suppressing mitochondrial mediated apoptosis and oxidative stress and by upregulating LXRα, thereby providing a rationale for future clinical trials and clinical applications.

Emerging evidence has shown that traditional Chinese medicine (TCM) has a positive effect on arthritis. This research provides the first critical, systematic examination of TCM practitioners' perceptions of TCM use for people with arthritis. An online survey was distributed to all TCM professionals including acupuncturists and Chinese herbal medicine practitioners registered with the Practitioner Research and Collaborate Initiative (PRACI) practitioner database. The survey questions focus on practitioner characteristics, practice characteristics and clinical management approaches regarding arthritis care. The survey attracted a response rate of 53% (n=52). The average age of the respondents was 49.9 years, more than half were female, and the majority held a bachelor degree or higher qualification. More than two thirds of TCM practitioners in our study worked with other health professionals, while they had a high level of referral relationships with a wide range of conventional, allied health and complementary and alternative medicine (CAM) providers. Most of the TCM practitioners reported that their patients with arthritis used other treatments alongside TCM and a large number of the TCM practitioners who participated believed that TCM was effective for treating arthritis. The TCM profession represents a substantial component of the healthcare field in Australia, and treating patients with arthritis appears to be an important area of TCM practice, among others. Further detailed research is needed to help ensure effective, safe patient care for those with arthritis who may be utilising TCM alongside a broader range of conventional medicine, allied health, and other CAM treatments. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2015-01-01

Allergic rhinitis (AR) is a common respiratory disease affecting both adults and children worldwide. Affected patients may experience nasal congestion/stuffiness, rhinorrhea (anterior and/or posterior), nasal/ nasopharyngeal itching and sneezing. Allergen avoidance is the principal step in the management. Nasal saline irrigation to remove allergen (s) in the nose is a useful adjunctive therapy in the management of moderate to severe AR. Symptomatic relief and improved quality of life may be achieved in the majority of patients with appropriate pharmacotherapy. Mild-to-moderate cases are usually managed with either an oral second generation antihistamine or an intranasal corticosteroid. More severe cases may require treatment with an intranasal corticosteroid in combination with various oral medications. Patients who require medications for more than 6 months per year or have intolerable side effects from pharmacotherapy can be considered for immunotherapy. A wide range of complementary and alternative medicines (CAM) have also been proposed. This overview evaluates the evidence of use of CAM for AR. Some methods including acupuncture and herbal medicine have supportive evidence, but the efficacy of other CAM is controversial. Conversely, possible side effects of different modalities are often inadequately documented. The herbal formulae include Butterbur, Nigella sativa, Shi-Bi-Lin, Polyherbal formula, Grapeseed extract, Rosmarinic acid, Spirulina, Biminne, and Bhu-zhong-yi-qi-tong. Further research is needed to assess the efficacy and safety before they are employed in treating AR. This review article also discusses recent CAM patents for use in AR, which are exclusively traditional Chinese medicine (TCM) concoctions primarily for oral consumption but two as topical spray. Only 8 pertinent patents, all TCM compositions for treating AR and registered in 2014, were obtained. Description about their efficacy is impressive but objective outcome evaluation tools are lacking.

Given the universal prevalence of complementary and alternative medicines, as well as integrative medicine, the usage of traditional medicine has been gaining in popularity worldwide. Japanese Kampo medicine and traditional Chinese medicine (TCM) are both derived from ancient medicines used in East Asia in the 5th-7th centuries, and have developed independently since the 14th century. Now Kampo medicine and TCM have different theories for the diagnosis and use of crude drugs. Unfortunately, Kampo medicine is not well known in Europe and the Americas; as a matter of practice, TCM is the international standard for traditional medicines derived from ancient East Asia. In the teaching of Kampo medicines to undergraduate students in a school of pharmacy, the author considers that a minimum requirement is to explain the differences between TCM and Kampo medicine. For graduate students of pharmaceutical science, the students must know the distinct medical theories of both TCM and Kampo medicine, and furthermore, must be able to read and write articles in English about traditional medicines, in order to help put Kampo medicine on the world map.

Traditional Chinese medicine (TCM) is a widely used complementary alternative medicine approach. Although many aspects of its effectiveness have been approved clinically, rigorous scientific techniques are highly required to translate the promises from TCM into powerful modern therapies. In this respect, proteomics is useful because of its ability to unveil the underlying target proteins and/or protein biomarkers. In this review, we summarize the recent interplay between proteomics and research on TCM, ranging from exploration of the medicinal materials to the biological basis of TCM concepts, and from pathological studies to pharmacological investigations. We show that proteomic analyses provide preliminary biological evidence of the promises in TCM, and the integration of proteomics with other omics and bioinformatics offers a comprehensive methodology to address the complications of TCM. Expert commentary: Currently, only limited information can be obtained regarding TCM issues and thus more work is required to resolve the ambiguity. As such, more collaborations between proteomics and other techniques (other omics, network pharmacology, etc.) are essential for deciphering the underlying biological basis in TCM topics.

A Modularity-Based Method Reveals Mixed Modules from Chemical-Gene Heterogeneous Network

For a multicomponent therapy, molecular network is essential to uncover its specific mode of action from a holistic perspective. The molecular system of a Traditional Chinese Medicine (TCM) formula can be represented by a 2-class heterogeneous network (2-HN), which typically includes chemical similarities, chemical-target interactions and gene interactions. An important premise of uncovering the molecular mechanism is to identify mixed modules from complex chemical-gene heterogeneous network of a TCM formula. We thus proposed a novel method (MixMod) based on mixed modularity to detect accurate mixed modules from 2-HNs. At first, we compared MixMod with Clauset-Newman-Moore algorithm (CNM), Markov Cluster algorithm (MCL), Infomap and Louvain on benchmark 2-HNs with known module structure. Results showed that MixMod was superior to other methods when 2-HNs had promiscuous module structure. Then these methods were tested on a real drug-target network, in which 88 disease clusters were regarded as real modules. MixMod could identify the most accurate mixed modules from the drug-target 2-HN (normalized mutual information 0.62 and classification accuracy 0.4524). In the end, MixMod was applied to the 2-HN of Buchang naoxintong capsule (BNC) and detected 49 mixed modules. By using enrichment analysis, we investigated five mixed modules that contained primary constituents of BNC intestinal absorption liquid. As a matter of fact, the findings of in vitro experiments using BNC intestinal absorption liquid were found to highly accord with previous analysis. Therefore, MixMod is an effective method to detect accurate mixed modules from chemical-gene heterogeneous networks and further uncover the molecular mechanism of multicomponent therapies, especially TCM formulae.

Deconstruction of molecular pathways and advances in enabling technology platforms have opened new horizons for disease management, exploring therapeutic solutions to each individual patient beyond the one-size fits all practice. Application of personalized medicine paradigms aims to achieve the right diagnosis and right treatment for the right patient at the right time at the right cost. With the potential to transform medical practice across global communities, personalized medicine is emerging as the flagship of modern medicine. In recent years, the health care paradigm has shifted from a focus on diseases to a major hot of personalized traditional Chinese medicine (TCM) with holistic approach. TCM focuses on health maintenance, emphasizes on enhancing the body's resistance to diseases and especially showes great advantages in early intervention, personalized and combination therapies, etc. Systems biology, a new science of the 21st century, becomes practically available and resembles TCM in many aspects such as study method and design, and is current key component technologies that serves as the major driving force for translation of the personalized medicine revolution of TCM principles into practice, will advance personalized therapy principles into healthcare management tools for individuals and populations. Such system approach concepts are transforming principles of TCM to modern therapeutic approaches, enable a predictive and preventive medicine and will lead to personalized medicine. To realise the full potential of personalized TCM, we describe the current status of principles and practice of TCM integrated with systems biology platform. Some characteristic examples are presented to highlight the application of this platform to personalized TCM research and development as well as some of the necessary milestones for moving TCM into mainstream health care.

In 1980, Wang Miqu proposed the concept of "The Psychology of Traditional Chinese Medicine (TCM Psychology)". In 1985, "The First National Symposium on Psychology of Traditional Chinese Medicine" was held, and the concept of TCM Psychology was put forward in the symposium, thus declaring the establishment of TCM Psychology, a new disciplinary branch. Since then, 12 national or international academic symposia of TCM Psychology were convened nationwide. Based on inheriting the original TCM, by means of exploring, sorting out and improving, and by combining and integrating with psychology and medical psychology, the theory of TCM Psychology was thus gradually innovated, and a systematic knowledge of TCM Psychology was set up and utilized in the clinical practice extensively.

In recent years, there has been an increasing worldwide interest in traditional Chinese medicine (TCM). This increasing demand for TCM needs to be accompanied by a deeper understanding of the mechanisms of action of TCM-based therapy. However, TCM is often described as a concept of Chinese philosophy, which is incomprehensible for Western medical society, thereby creating a gap between TCM and Western medicine (WM). In order to meet this challenge, TCM research has applied proteomics technologies for exploring the mechanisms of action of TCM treatment. Proteomics enables TCM researchers to oversee various pathways that are affected by treatment, as well as the dynamics of their interactions with one another. This review discusses the utility of comparative proteomics to better understand how TCM treatment may be used as a complementary therapy for Alzheimer's disease (AD). Additionally, we review the data from comparative AD-related TCM proteomics studies and establish the relevance of the data with available AD hypotheses, most notably regarding the ubiquitin proteasome system (UPS).

With the development of the modernization drive of traditional Chinese medicine (TCM) preparations, new-type TCM dosage forms research have become a hot spot in the field. Because of complexity of TCM components as well as uncertainty of material base, there is still not a scientific system for modern TCM dosage forms so far. Modern TCM preparations inevitably take the nature of the multi-component and the general function characteristics of multi-link and multi-target into account. The author suggests building a multiple drug release system for TCM using diverse preparation techniques and drug release methods at levels on the basis the nature and function characteristics of TCM components. This essay expounds elaborates the ideas to build the multiple traditional Chinese medicine release system, theoretical basis, preparation techniques and assessment system, current problems and solutions, in order to build a multiple TCM release system with a view of enhancing the bioavailability of TCM components and provide a new form for TCM preparations.

Traditional Chinese Medicine as a Basis for Treating Psychiatric Disorders: A Review of Theory with Illustrative Cases

PubMed Central

Aung, Steven K.H.; Fay, Heather

2013-01-01

Abstract Background: Integrative medicine is becoming increasingly accepted in the global scheme of health care. Traditional Chinese Medicine (TCM) is often included among integrative medicine modalities. Objective: This article provides a background for integration of acupuncture and other TCM-derived approaches to managing psychiatric conditions. Methods: Classical theories of TCM that pertain to psychiatric conditions are reviewed, focusing on concepts of energetic imbalance, the implications of mind–body–spirit connections, and treatment strategies that involve TCM modalities. An example of correlation between TCM patterns of disharmony and the Western diagnosis of generalized anxiety disorder (GAD) is given, along with an illustrative case in which counseling, medications, and acupuncture were combined in treatment. TCM principles are incorporated in certain energy psychology modalities, such as Emotional Freedom Technique (EFT). A case is presented demonstrating the integration of energy psychology with acupuncture, Qigong and hypnosis as an avenue for releasing pathogenic emotions. In classical TCM theory, assessing and treating spiritual disharmonies is fundamental for dealing with emotional disorders. Practical application in a clinical case is described. Conclusions: TCM offers a cogent theoretical basis for assessing and clinically managing patients presenting with mental health issues. TCM principles integrate well with other systems, including Western medicine. PMID:24761185

Traditional Chinese medicine ZHENG and Omics convergence: a systems approach to post-genomics medicine in a global world.

PubMed

Wang, Peng; Chen, Zhen

2013-09-01

Traditional Chinese medicine (TCM) is a comprehensive system of medical practice that has been used to diagnose, treat, and prevent illnesses for more than 3000 years. ZHENG (also known as "syndrome") differentiation remains the essence of TCM. In China, TCM shares equal status, and integrated with Western medicine in the healthcare system to treat many types of diseases. Yet, compared to biomolecular science and Western medicine, the ZHENG/TCM approach to diagnostics might appear unobjective, but offers at the same time long-standing clinical and phenotypic-rich insights. With the current globalization of life sciences and the arrival of "Big Data" research and development, these two silos of medical lore are rapidly coalescing. The applications of multi-omics strategies to TCM have begun to provide novel insights into the essence and molecular basis of TCM ZHENG. We searched the Chinese electronic databases and PubMed for published articles related to "Omics" and "TCM ZHENG" and observed a dramatic increase in studies over the past few years. In this article, we provide a timely synthesis of the lessons learned, and the emerging applications of omics science in TCM ZHENG research. We suggest that the global health scholarship and the field of "developing world Omics" can usefully draw from TCM, and vice versa.

Functional abdominal pain syndrome (FAPS) is one of the less common functional gastrointestinal disorders. Conventional therapy has unsatisfactory response to it so people turn to Chinese medicine for help. Currently, we reviewed the whole picture of Chinese herbal medicine (CHM) clinical and basic application in the treatment of FAPS, especially the traditional Chinese medicine (TCM) syndrome, the single herb, and Chinese medicine formulae, thus to provide a solid base to further develop evidence-based study for this common gastrointestinal complaint in the future. We developed the search strategy and set the inclusion and exclusion criteria for article search. From the included articles, we totally retrieved 586 records according to our searching criteria, of which 16 were duplicate records and 291 were excluded for reasons of irrelevance. The full text of 279 articles was retrieved for detailed assessment, of which 123 were excluded for various reasons. The number one used single herb is Radix Ginseng. The most common syndrome was liver qi depression. The most frequently used classic formula was Si-Mo-Tang. This reflected the true situation of clinical practice of Chinese medicine practitioners and could be further systematically synthesized as key points of the therapeutic research for FAPS.

To enhance therapeutic efficacy and reduce adverse effects, practitioners of traditional Chinese medicine (TCM) prescribe a combination of plant species/minerals, called formulae, based on clinical experience. Nearly 100,000 formulae have been recorded, but the working mechanisms of most remain unknown. In trying to address the possible beneficial effects of formulae with current biomedical approaches, we use Realgar-Indigo naturalis formula (RIF), which has been proven to be very effective in treating human acute promyelocytic leukemia (APL) as a model. The main components of RIF are realgar, Indigo naturalis, and Salvia miltiorrhiza, with tetraarsenic tetrasulfide (A), indirubin (I), and tanshinone IIA (T) as major active ingredients, respectively. Here, we report that the ATI combination yields synergy in the treatment of a murine APL model in vivo and in the induction of APL cell differentiation in vitro. ATI causes intensified ubiquitination/degradation of promyelocytic leukemia (PML)-retinoic acid receptor alpha (RARalpha) oncoprotein, stronger reprogramming of myeloid differentiation regulators, and enhanced G(1)/G(0) arrest in APL cells through hitting multiple targets compared with the effects of mono- or biagents. Furthermore, ATI intensifies the expression of Aquaglyceroporin 9 and facilitates the transportation of A into APL cells, which in turn enhances A-mediated PML-RARalpha degradation and therapeutic efficacy. Our data also indicate A as the principal component of the formula, whereas T and I serve as adjuvant ingredients. We therefore suggest that dissecting the mode of action of clinically effective formulae at the molecular, cellular, and organism levels may be a good strategy in exploring the value of traditional medicine.

The clinical evaluation system for therapeutic effects of tumor, which focuses on survival period and tumor response rate, has been proved not very proper for evaluating the therapeutic effects of traditional Chinese medicine (TCM). Quality of life (QOL) has been introduced into the effective evaluation system of TCM and integrative medicine because of its similarity in concept and extension with TCM at theory basis, syndrome differentiation-treatment, and evaluation of therapeutic effects. But there are no QOL questionnaires which can evaluate the therapeutic effects of TCM and integrative medicine precisely. This article discussed the necessity and significance of developing QOL questionnaire special for TCM.

Background Evidence-based medicine promotes and relies on the use of evidence in developing clinical practice guidelines (CPGs). The Chinese healthcare system includes both traditional Chinese medicine (TCM) and Western medicine, which are expected to be equally reflected in Chinese CPGs. Objective To evaluate the inclusion of TCM-related information in Western medicine CPGs developed in China and the adoption of high level evidence. Methods All CPGs were identified from the China Guideline Clearinghouse (CGC), which is the main Chinese organisation maintaining the guidelines issued by the Ministry of Health of China, the Chinese Medical Association and the Chinese Medical Doctors’ Association. TCM-related contents were extracted from all the CPGs identified. Extracted information comprised the institution issuing the guideline, date of issue, disease, recommendations relating to TCM, evidence level of the recommended content and references supporting the recommendations. Results A total of 604 CPGs were identified, only a small number of which (74/604; 12%) recommended TCM therapy and only five guidelines (7%) had applied evidence grading. The 74 CPGs involved 13 disease systems according to the International Classification of Diseases 10th edition. TCM was mainly recommended in the treatment part of the guidelines (73/74, 99%), and more than half of the recommendations (43/74, 58%) were related to Chinese herbal medicine (single herbs or herbal treatment based on syndrome differentiation). Conclusions Few Chinese Western medicine CPGs recommend TCM therapies and very few provide evidence grading for the TCM recommendation. We suggest that future guideline development should be based on systematic searches for evidence to support CPG recommendations and involve a multidisciplinary approach including TCM expertise.

The industry of traditional Chinese medicine (TCM) encounters problems like quality fluctuation of raw materials and unstandardized production process. Near infrared (NIR) spectroscopy technology is widely used in quality control of TCM because of its abundant information, fast and nondestructive characters. The main applications include quantitative analysis of Chinese medicinal materials, intermediates and Chinese patent medicines; the authenticity of TCM, species, origins and manufacturers; monitoring and control of the extraction, alcohol precipitation, column chromatography and blending process. This article reviews the progress on the application of NIR spectroscopy technology in TCM field. In view of the problems existing in the application, the article proposes that the standardization of NIR analysis method should be developed according to specific characteristics of TCM, which will promote the application of NIR technology in the TCM industry.

'Huang Qi Elixir' for proteinuria in patients with diabetic nephropathy: a study protocol for a randomized controlled pilot trial.

Diabetic nephropathy (DN) is the major complication of diabetes; proteinuria is the hall mark of DN. Currently, the treatment for proteinuria is mainly limited to angiotensin converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs). According to Traditional Chinese Medicine (TCM) theory, Chinese medicinals 'securing essence and tonifying the kidney' may be appropriate for proteinuria. The most promising Chinese medicinals and formulae are introduced in the present study to form a potent formula for DN proteinuria. To make oral administration convenient, the formula will be processed in the form of granules. A randomized, multi-center pilot trial will be conducted. Forty eight participants with DN will be randomly assigned to one of four treatment groups: 1. A granule group, at 10 grams, three times daily (G10 group, n = 12); 2. A granule group, at 20 grams, three times daily (G20 group, n = 12); 3. A decoction group (D group, n = 12); and 4. An irbesartan group (Aprovel group, n = 12).The following outcome measures will be used: the percentage change of the albumin-to-creatinine ratio; and the changes in serum creatinine, glomerular filtration rate, fasting plasma glucose and hemoglobulin from baseline to the end of the trial. It is notable that most published clinical trials which assessed the efficacy of TCM on DN were of poor methodology and, therefore, their results have been invalidated. It is necessary to carry out well-designed clinical trials to provide sound evidence. The present trial is a study with potentially great value, for it will provide the parameters for future randomized, placebo-controlled, clinical trials with large sample sizes. The trial is registered on the Chinese Clinical Trial Registry: ChiCTR-TRC-12002718 (http://www.chictr.org/cn/proj/show.aspx?proj=3820).

Adaptation is an eternal theme of biological evolution. The paper aims at exploring the conception of positive correlation between traditional Chinese medicine (TCM) and human homeostatic evolution based on medical perspective. Discussions mainly involve TCM conforming to natural laws and natural evolution of life, spontaneous harmonization of yin and yang and operating system of human self-healing, modern human immunology and human endogenous immune function in TCM, self-homeostasis of human micro-ecological state and balance mechanism on regulating base in TCM, as well as adaptation-eternal theme of biological evolution and safeguarding adaptability-value of TCM. In perspective of medicine, theory and practice of TCM are in positive correlation with human homeostatic evolution, and what TCM tries to maintain is human intrinsic adaptive capability to disease and nature. Therefore, it is the core value of TCM, which is to be further studied, explored, realized and known to the world.

Both Yun Tie-qiao and Lu Yuan-lei are medical professionals coming from the literary field with versatile and in-depth knowledge and extensive experience in medical education and clinical practice, all closely related to modern TCM development. Yun, the elder, insisted on reforming TCM and was early to advocate the academic idea of amalgamating western and traditional Chinese medicine; while Lu, the younger, insisted on the idea of "scientizing TCM" and was the representative of amalgamating western and traditional Chinese medicine in the later stage. They shared many common viewpoints, including venerating Zhang Zhongjing, stressing exogenous cold pathogens, advocating reformation and amalgamation of western medicine and TCM and objecting to the abolishment of TCM. However, there were discrepancies between them, including the relationship between the Inner Canon and the Essay on Exogenous Cold Diseases, warm disease theory, pulse theory, titles of TCM diseases and Japanese Kampo medicine. A comparison of them and noting their valuable contributions will be beneficial for the promotion of the development of TCM.

The beginnings of traditional Chinese medicine (TCM) can be related to the three most important philosophic and religious personalities. Modern Western medicine (MM), which was already sensationally successful at that time, was brought to China by business men, missionaries and soldiers. Compared to MM, the theories of TCM seem abstract, its concept unusual. Historical hallmarks of TCM influenced by culture are the following: the medical system is philosophical, oriented towards humanism. TCM is a medical system without strict structural relationships (without anatomy).

Traditional Chinese Medicine (TCM) is widely practised and is viewed as an attractive alternative to conventional medicine. Quantitative information about TCM prescriptions, constituent herbs and herbal ingredients is necessary for studying and exploring TCM. We manually collected information on TCM in books and other printed sources in Medline. The Traditional Chinese Medicine Information Database TCM-ID, at http://tcm.cz3.nus.edu.sg/group/tcm-id/tcmid.asp, was introduced for providing comprehensive information about all aspects of TCM including prescriptions, constituent herbs, herbal ingredients, molecular structure and functional properties of active ingredients, therapeutic and side effects, clinical indication and application and related matters. TCM-ID currently contains information for 1,588 prescriptions, 1,313 herbs, 5,669 herbal ingredients, and the 3D structure of 3,725 herbal ingredients. The value of the data in TCM-ID was illustrated by using some of the data for an in-silico study of molecular mechanism of the therapeutic effects of herbal ingredients and for developing a computer program to validate TCM multi-herb preparations. The development of systems biology has led to a new design principle for therapeutic intervention strategy, the concept of 'magic shrapnel' (rather than the 'magic bullet'), involving many drugs against multiple targets, administered in a single treatment. TCM offers an extensive source of examples of this concept in which several active ingredients in one prescription are aimed at numerous targets and work together to provide therapeutic benefit. The database and its mining applications described here represent early efforts toward exploring TCM for new theories in drug discovery.

Traditional Chinese medicine (TCM) is currently the best-preserved and most influential traditional medical system with the largest number of users worldwide. In recent years, the trend of TCM adoption has increased greatly, but the process of TCM internationalization has suffered from a series of setbacks for both internal and external reasons. Thus, the process of TCM internationalization faces formidable challenges, although it also has favourable opportunities. Using SWOT analysis, this paper investigates the strengths, weaknesses, opportunities and threats for TCM. These findings can serve as references for TCM enterprises with global ambitions.

To discover and develop novel natural compounds, active ingredients, single herbs and combination formulas or prescriptions in traditional Chinese medicine (TCM) with therapeutic selectivity that can preferentially kill cancer cells and inhibit the amplification of cancer without significant toxicity is an important area in cancer therapy. A lot of valuable TCMs were applied as alternative or complementary medicines in the United States and Europe. But these TCMs, as one of the main natural resources, were widely used to research and develop new drugs in Asia. In TCMs, some specific herbs, animals, minerals and combination formulas were recorded and exploited due to their active ingredients and specific natural compounds with antitumor activities. The article focused on the antitumor properties of natural compounds and combination formulas or prescriptions in TCMs, described its influence on tumor progression, angiogenesis, metastasis, and revealed its mechanisms of antitumor and inhibitory action. Among the nature compounds, triptolide, berberine, matrine, oxymatrine, kurarinone and deoxypodophyllotoxin (DPT) with specific molecular structures have been separated, purified, and evaluated their antitumor properties in vitro and in vivo. Cancer is a multifactorial and multistep disease, so the treatment effect of combination formulas and prescriptions in TCMs involving multi-targets and multi-signal pathways on tumor may be superior than that of agents targeting a single molecular target alone. Shi Quan Da Bu Tang and Yanshu injection, as well known combination formulas and prescriptions in TCMs, have shown an excellent therapeutic effect on cancer.

Patients with a polyherbal prescription are more likely to receive duplicate medications and thus suffer from adverse drug reactions. We conducted a population-based retrospective study to examine the items of Chinese herbal medicine (CHM) per prescription in the ambulatory care of traditional Chinese medicine (TCM) in Taiwan. We retrieved complete TCM ambulatory visit datasets for 2010 from the National Health Insurance database in Taiwan. A total of 59,790 patients who received 313,482 CHM prescriptions were analyzed. Drug prescriptions containing more than five drugs were classified as polyherbal prescriptions; 41.6% of patients were given a polyherbal prescription. There were on average 5.2 ± 2.5 CHMs: 2.3 ± 1.1 compound herbal formula items, and 3.0 ± 2.5 single Chinese herb items in a single prescription. Approximately 4.6% of patients were prescribed 10 CHMs or more. Men had a lower odds ratio (OR) among polyherbal prescriptions (OR = 0.96, 95% confidence interval [CI] 0.92–0.99), and middle-aged patients (35–49 years) had the highest frequency of polyherbal prescription (OR = 1.19, 95% CI = 1.13–1.26). Patients with neoplasm, skin and subcutaneous tissue disease, or genitourinary system disease were more likely to have a polyherbal prescription; OR = 2.20 (1.81–2.67), 1.65 (1.50–1.80), and 1.52 (1.40–1.64), respectively. Polyherbal prescription is widespread in TCM in Taiwan. Potential herb interactions and iatrogenic risks associated with polyherbal prescriptions should be monitored. PMID:26287228

Chronic obstructive pulmonary disease (COPD) affects millions worldwide. Although many therapies exist and are being developed to relieve symptoms and reduce mortality, few data are available to understand which of the therapeutic alternatives is the most cost-effective for COPD patients in everyday clinical practice, especially for traditional Chinese medicine (TCM). Comparative effectiveness research can help patients, clinicians, and decision-makers make best informed treatment decisions where such evidence was previously lacking. This study aims to compare the effectiveness and economic evaluation of three treatments: (1) conventional Western medicine; (2) TCM treatments, which have been evaluated and have certain effect; and (3) a combination of both conventional Western medicine and TCM treatments, and then determine which treatment is the most suitable for COPD patients. A multicenter, pragmatic, randomized, controlled trial is adopted. A total of 360 patients will be recruited and randomly assigned to one of the three treatments group, with 120 in each group. Patients in the conventional Western medicine group will be given Salbutamol, Formoterol, Salmeterol/fluticasone, respectively, according to the guidelines. For the TCM group, patients will be given Bufei granule, Bu-Fei Jian-Pi granule, Bu-Fei Yi-Shen granule, and Yi-Qi Zi-Shen granule based on their corresponding TCM syndrome patterns, respectively. For the combination of conventional medicine and TCM treatments group, patients will be given a combination of conventional Western medicine and TCM granules. Treatments in each group are recognized as a whole comprehensive intervention. After the 26-week treatment, another 26 weeks will be followed up. The outcome measures including the frequency and duration of acute exacerbations, lung function, dyspnea, exercise capacity, quality of life, and economic evaluation will be assessed. It is hypothesized that each of the three treatments will have beneficial effects in reducing the frequency and duration of acute exacerbations, improving exercise capacity and psychosocial function of COPD patients. In addition, the combination of conventional medicine and TCM treatments may be most suitable for COPD patients with better effectiveness and economic evaluation. ClinicalTrials.gov NCT01836016.

"High quality, safety and effectiveness" are the primary principles for the pharmaceutical research and development process in China. The quality of products relies not only on the inspection method, but also on the design and development, process control and standardized management. The quality depends on the process control level. In this paper, the history and current development of quality control of traditional Chinese medicine (TCM) preparations are reviewed systematically. Based on the development model of international drug quality control and the misunderstanding of quality control of TCM preparations, the reasons for impacting the homogeneity of TCM preparations are analyzed and summarized. According to TCM characteristics, efforts were made to control the diversity of TCM, make "unstable" TCM into "stable" Chinese patent medicines, put forward the concepts of "holistic view" and "QbD (quality by design)", so as to create the "holistic, modular, data, standardized" model as the core of TCM preparation quality process control model. Scientific studies shall conform to the actual production of TCM preparations, and be conducive to supporting advanced equipment and technology upgrade, thoroughly applying the scientific research achievements in Chinese patent medicines, and promoting the cluster application and transformation application of TCM pharmaceutical technology, so as to improve the quality and effectiveness of the TCM industry and realize the green development.

Phthalides are important bio-active constituents in Si-Wu-Tang and Fo-Shou-San, two commonly used Traditional Chinese Medicine (TCM) combined prescriptions mainly derived from Radix Angelica and Rhizoma Chuanxiong. In this paper, the contents of eight phthalides, including Z-ligustilide, E-ligustilide, Z-butylenephthalide, E-butylene-phthalide, 3-butylphthalide, neocnidilide and senkyunolide A were determined or estimated by gas chromatography-mass spectrometry (GC-MS). The results showed GC-MS was a simple, rapid, and high sensitive method for analyzing phthalides in Si-Wu-Tang, Fo-Shou-San, Radix Angelica and Rhizoma Chuanxiong, and the extractable contents of each phthalides including Z-ligustilide, E-ligustilide, Z-butylenephthalide, etc. varied after Radix Angelica, Rhizoma Chuanxiong were combined into a formulation, such as Si-Wu-Tang and Fo-Shou-San. Furthermore, inhibition activity of essential oils from Si-Wu-Tang, Fo-Shou-San, Radix Angelica and Rhizoma Chuanxiong on uterine contraction was tested in an in vitro assay, and the results showed that the activity of the essential oil is higher as the content of the phthalides increase, which demonstrated that phthalides are possibly main active components inhibiting mice uterine contraction in vitro. All of the results suggested that comparative analysis of chemical components and pharmacological activities of each herb and formula is possibly helpful to elucidate the active components in traditional Chinese medicine, and to reveal the compatibility mechanism of TCM formulae.

Andrology has a long history in traditional Chinese medicine (TCM) discussions concerning andropathies, and documentation of relevant therapeutic methods abound in the ancient literature on TCM. Integrated treatment combining TCM and Western medicine has seen both broad and in-depth development, with formidable status in the field of modern andrology in China. This article attempts to demonstrate the unique advantage of integrated treatment in the therapy of andropathies through a review of the ancient literature on andrology in the field of TCM and on the integrative treatment of prostatic diseases, sexual dysfunction, male infertility and late-onset hypogonadism. There is a need for the advancement of a medical theory that integrates TCM and Western medicine practices to create a new therapeutic system with standardized therapeutic and evaluative protocols for diseases involving male sexual health.

The introduction and popularization of evidence-based medicine has opened up a new research field of clinical efficacy evaluation of traditional Chinese medicine(TCM), produced new research ideas and methods, and promoted the progress of clinical research of TCM. After about 20 years assiduous study and earnest practice, the evidence based evaluation method and technique, which conforms to the characteristics of TCM theory and practice, has been developing continuously. Evidence-based Chinese medicine (EBCM) has gradually formed and become an important branch of evidence-based medicine. The basic concept of evidence-based Chinese medicine: EBCM is an applied discipline, following the theory and methodology of evidence-based medicine, to collect, evaluate, produce, transform the evidence of effectiveness, safety and economy of TCM, to reveal the feature and regular pattern of TCM taking effect, and to guide the development of clinical guidelines, clinical pathways and health decisions. The effects and achievements of EBCM development: secondary studies mainly based on systematic review/Meta-analysis were extensively carried out; clinical efficacy studies mainly relying on randomized controlled trials grew rapidly; clinical safety evaluations based on real world study have been conducted; methodological researches mainly focused on study quality control deepened gradually; internationalization researches mainly on report specifications have got some breakthroughs; standardization researches based on treatment specification were strengthened gradually; the research team and talents with the characteristics of inter-disciplinary have been steadily increased. A number of high-quality research findings have been published at international well-known journals; the clinical efficacy and safety evidence of TCM has been increased; the level of clinical rational use of TCM has been improved; a large number of Chinese patent medicines with big market have been cultured. The future missions of EBCM mainly consist of four categories (scientific research, methodology and standard, platform construction and personnel training) with nine tasks. ①Carry out systematic reviews to systematically collect clinical trial reports of TCM and establish database of clinical evidence of TCM; ②Carry out evidence transformation research to lay the foundation for the development of clinical diagnosis and treatment guidelines, clinical pathways of TCM, and for the screening of basic drug list and medical insurance list, and for the policy-making relevant to TCM; ③Conduct researches to evaluate the advantages and effective regular patterns of TCM and form the evidence chain of TCM efficacy; ④Carry out researches for the safety evaluation of TCM, and provide evidence supporting the rational and safe use of TCM in clinical practice; ⑤Conduct researches on methodology of EBCM and provide method for developing high quality evidence; ⑥Carry out researches to develop standards and norms of TCM, and to form methods, standards, specifications and technical systems; ⑦Establish data management platform for evidence-based evaluation of TCM, and promote data sharing; ⑧Build international academic exchange platform to promote international cooperation and mutual recognition of EBCM research; ⑨Carry out education and popularization activities of evidence-based evaluation methods, and train undergraduate students, graduate students, clinical healthcare providers and practitioners of TCM.

Dry eye is a common health problem worldwide, causing significant discomfort and inconvenience to sufferers. The conventional treatment of dry eye via topical administration of eye drops is deemed palliative and unsatisfactory to many. Traditional Chinese medicine (TCM) has shown some promise in dry eye treatment; however, the extent of its use and acceptance is uncertain. We evaluated the knowledge, attitude, and practice of institutional TCM practitioners in the treatment of dry eye in Singapore. A questionnaire was generated to address the study aims and sent to TCM practitioners listed in the Singapore TCM practitioners' board database. About three quarters of respondents thought that dry eye was not severe enough to be a public health burden but most thought that TCM was effective in the treatment of dry eye. Acupuncture and herbal medicine were most commonly used TCM modalities in dry eye treatment, and a single TCM treatment session would be charged S$20–50 by the practitioner. The majority of surveyed institutional TCM practitioners in Singapore believe that TCM is relevant in dry eye treatment. Public awareness should be raised regarding the availability of TCM as alternative medicine for dry eye. PMID:23213306

Traditional Chinese Medicine Physicians' Insights into Interprofessional Tensions between Traditional Chinese Medicine and Biomedicine: A Critical Perspective.

Chang, Leanne; Lim, Jing Ci Jill

In Singapore, the institutional preference for biomedicine and the cultural importance of traditional Chinese medicine (TCM) have created tensions between the two medical systems and erected barriers to a more collaborative health-care system. This study foregrounds TCM physicians' voice to reveal ideological struggles and power imbalances that underlie the interprofessional tensions and accompanying marginalization of TCM. Through in-depth interviews with 22 TCM physicians in Singapore, this study reveals the incongruences in ideological underpinnings between biomedicine and TCM, reflected in their different worldviews and epistemological approaches to knowledge formation and evaluation. Power differentials between the two medical systems are manifest in TCM physicians' inferior position in relation to their biomedical peers, the patients' internalization of biomedical standards to question the TCM profession and their own interest in seeking TCM treatments, and the state's limited support for TCM research, subsidies, and service provision in hospital settings. The results suggest that more open dialogue about the dichotomous framings of biomedicine and TCM is key to disrupting the mutual reinforcement of ideology and power, as well as to creating increased mutual understanding between the two medical systems.

Chinese herbal medicine (CHM) has been commonly used for treating insomnia in Asian countries for centuries. The aim of this study was to conduct a large-scale pharmaco-epidemiologic study and evaluate the frequency and patterns of CHM use in treating insomnia. We obtained the traditional Chinese medicine (TCM) outpatient claims from the National Health Insurance in Taiwan for the year 2002. Patients with insomnia were identified from the diagnostic code of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and an association rule was applied to evaluate the co-prescription of CHM. Results showed that there were 16 134 subjects who visited TCM clinics for insomnia in Taiwan during 2002 and received a total of 29 801 CHM prescriptions. Subjects between 40 and 49 years of age comprised the largest number of those treated (25.3%). In addition, female subjects used CHMs for insomnia more frequently than male subjects (female : male = 1.94 : 1). There was an average of 4.8 items prescribed in the form of either an individual Chinese herb or formula in a single CHM prescription for insomnia. Shou-wu-teng (Polygonum multiflorum) was the most commonly prescribed single Chinese herb, while Suan-zao-ren-tang was the most commonly prescribed Chinese herbal formula. According to the association rule, the most commonly prescribed CHM drug combination was Suan-zao-ren-tang plus Long-dan-xie-gan-tang, while the most commonly prescribed triple drug combination was Suan-zao-ren-tang, Albizia julibrissin, and P. multiflorum. Nevertheless, further clinical trials are needed to evaluate the efficacy and safety of these CHMs for treating insomnia. PMID:19339485

To enhance therapeutic efficacy and reduce adverse effects, practitioners of traditional Chinese medicine (TCM) prescribe a combination of plant species/minerals, called formulae, based on clinical experience. Nearly 100,000 formulae have been recorded, but the working mechanisms of most remain unknown. In trying to address the possible beneficial effects of formulae with current biomedical approaches, we use Realgar-Indigo naturalis formula (RIF), which has been proven to be very effective in treating human acute promyelocytic leukemia (APL) as a model. The main components of RIF are realgar, Indigo naturalis, and Salvia miltiorrhiza, with tetraarsenic tetrasulfide (A), indirubin (I), and tanshinone IIA (T) as major active ingredients, respectively. Here, we report that the ATI combination yields synergy in the treatment of a murine APL model in vivo and in the induction of APL cell differentiation in vitro. ATI causes intensified ubiquitination/degradation of promyelocytic leukemia (PML)-retinoic acid receptor α (RARα) oncoprotein, stronger reprogramming of myeloid differentiation regulators, and enhanced G1/G0 arrest in APL cells through hitting multiple targets compared with the effects of mono- or biagents. Furthermore, ATI intensifies the expression of Aquaglyceroporin 9 and facilitates the transportation of A into APL cells, which in turn enhances A-mediated PML-RARα degradation and therapeutic efficacy. Our data also indicate A as the principal component of the formula, whereas T and I serve as adjuvant ingredients. We therefore suggest that dissecting the mode of action of clinically effective formulae at the molecular, cellular, and organism levels may be a good strategy in exploring the value of traditional medicine.

Biological, psychological and sociological model of medicine substantializes the old model lacking the social humane attributes. The new medical model makes people take medical anthropology into research and highly evaluate traditional medical system. Cultural anthropology of traditional Chinese medicine (TCM) is part of medical anthropology with three major characteristics: wide research scope, specificity, and integration. It has developed its own research methods, such as field investigation, comprehensive inspection and comparison study. Cultural anthropology provides an efficient research method for TCM, and its application would further develop TCM theory and form comprehensive evaluation on TCM effects.

Comparison of Sasang Constitutional Medicine, Traditional Chinese Medicine and Ayurveda

Sasang constitutional medicine (SCM), traditional Chinese medicine (TCM) and Ayurveda are three different forms of Asian traditional medicine. Although these traditions share a lot in common as holistic medicines, the different philosophical foundations found in each confer distinguishing attributes and unique qualities. SCM is based on a constitution-based approach, and is in this way relatively more similar to the Ayurvedic tradition than to the TCM, although many of the basic SCM theories were originally derived from TCM, a syndrome-based medicine. SCM and TCM use the same botanical materials that are distributed mainly in the East Asian region, but the basic principles of usage and the underlying rationale are completely different from each other. Meanwhile, the principles of the Ayurvedic use of botanical resources are very similar to those seen in SCM, but the medicinal herbs used in Ayurveda generally originate from the West Asian region which displays a different spectrum of flora.

In post-marketing study of traditional Chinese medicine (TCM), pharmacoeconomic evaluation has an important applied significance. However, the economic literatures of TCM have been unable to fully and accurately reflect the unique overall outcomes of treatment with TCM. For the special nature of TCM itself, we recommend that Markov model could be introduced into post-marketing pharmacoeconomic evaluation of TCM, and also explore the feasibility of model application. Markov model can extrapolate the study time horizon, suit with effectiveness indicators of TCM, and provide measurable comprehensive outcome. In addition, Markov model can promote the development of TCM quality of life scale and the methodology of post-marketing pharmacoeconomic evaluation.

The primary prevention of disease related to the lifestyle is an essential theme in medical research. Preventing before it arises is the important concept in traditional Chinese medicine (TCM). Since TCM, which emphasizes individual physical condition in medical treatment, has recently attracted considerable attention globally, objective diagnostic methods in TCM have been investigated in this work. Firstly, the fuzzy theory was applied to develop a tongue diagnosis supporting system based on the tongue diagnosis in TCM. Secondly, the usefulness of TCM health questionnaire was examined to identify individual physical condition. Our results suggest that the TCM health questionnaire is useful in the construction of a health supporting system based on TCM.

A dispute about the decreasing-price problem of traditional Chinese medicine (TCM) has recently arisen. This article analyzes the statistical data of 1995-2011 in China, the results showed that the main responsibility of expensive health care has no direct relationship with the drug price. The price index of TCM rose significantly slower than the medicine prices, the production margins of TCM affected by the material prices has been diminishing since 1995, continuous price reduction will further depress profits of the TCM industry. Considering the pros and cons of raw materials vary greatly in price, decreasing medicine price behavior will force enterprises to use inferior materials in order to maintain corporate profits. The results have the guiding meaning to medicine price management.

Cancer patients suffer from diverse symptoms, including depression, anxiety, pain, and fatigue and lower quality of life (QoL) during disease progression. This study aimed to evaluate the benefits of Traditional Chinese Medicine psycho-behavioral interventions (TCM PBIs) on improving QoL by meta-analysis. The six TCM PBIs analyzed were acupuncture, Chinese massage, Traditional Chinese Medicine five elements musical intervention (TCM FEMI), Traditional Chinese Medicine dietary supplement (TCM DS), Qigong and Tai Chi. Although both TCM PBIs and non-TCM PBIs reduced functional impairments in cancer patients and led to pain relief, depression remission, reduced time to flatulence following surgery and sleep improvement, TCM PBIs showed more beneficial effects as assessed by reducing both fatigue and gastrointestinal distress. In particular, acupuncture relieved fatigue, reduced diarrhea and decreased time to flatulence after surgery in cancer patients, while therapeutic Chinese massage reduced time to flatulence and time to peristaltic sound. Electronic literature databases (PubMed, CNKI, VIP, and Wanfang) were searched for randomized, controlled trials conducted in China. The primary intervention was TCM PBIs. The main outcome was health-related QoL (HR QoL) post-treatment. We applied standard meta analytic techniques to analyze data from papers that reached acceptable criteria. These findings demonstrate the efficacy of TCM PBIs in improving QoL in cancer patients and establish that TCM PBIs represent beneficial adjunctive therapies for cancer patients.

Evidence-based medicine (EBM), by integrating individual clinical expertise with the best available clinical evidence from systematic research, has in recent years been established as the standard of modern medical practice for greater treatment efficacy and safety. Traditional Chinese Medicine (TCM), on the other hand, evolved as a system of medical practice from ancient China more than 2000 years ago based on empirical knowledge as well as theories and concepts which are yet to be mapped by scientific equivalents. Despite the expanding TCM usage and the recognition of its therapeutic benefits worldwide, the lack of robust evidence from the EBM perspective is hindering acceptance of TCM by the Western medicine community and its integration into mainstream healthcare. For TCM to become an integral component of the healthcare system so that its benefits can be rationally harnessed in the best interests of patients, it is essential for TCM to demonstrate its efficacy and safety by high-level evidence in accordance with EBM, though much debate remains on the validity and feasibility of applying the EBM model on this traditional practice. This review aims to discuss the current status of research in TCM, explore the evidences available on its efficacy and safety, and highlight the issues and challenges faced in applying EBM to TCM.

Toxic classification of traditional Chinese medicine, as a contribution of traditional Chinese medicine (TCM) to the recognition of medicinal toxicity and rational use of medicinal materials by Chinese people, is now a great issue related to safe medication, sustainable development and internationalization of Chinese medicine. In this article, the origination and development of toxic classification theory was summarized and analyzed. Because toxic classification is an urgent issue related to TCM industrialization, modernization and internationalization, this article made a systematic analysis on the nature and connotation of toxic classification as well as risk control for TCM industry due to the medicinal toxicity. Based on the toxic studies, this article made some recommendations on toxic classification of Chinese medicinal materials for the revision of China Pharmacopeia (volume 1). From the aspect of scientific research, a new technical guideline for research on toxic classification of Chinese medicine should be formulated based on new biological toxicity test technology such as Microtox and ADME/Tox, because the present classification of acute toxicity of mice/rats can not met the modern development of Chinese medicine any more. The evaluation system and technical SOP of TCM toxic classification should also be established, and they should well balance TCM features, superiority and international requirements. From the aspect of medicine management, list of toxic medicines and their risk classification should be further improved by competent government according to scientific research. In China Pharmacopeia (volume I), such descriptions of strong toxicity, toxicity or mild toxicity should be abandoned when describing medicine nature and flavor. This revision might help promote TCM sustainable development and internationalization, and enhance the competitive capacity of Chinese medicine in both domestic and international market. However, description of strong toxicity, toxicity or mild toxicity might be used when making cautions for the medicine, stating that the description is based on Chinese classic works. In this way, TCM traditional theory might be inherited and features of Chinese medicine maintained and reflected. Besides, modern findings should be added to the cautions, including dose-response relationship, toxic mechanism, and toxic elements. The traditional toxic descriptions and modern findings, as a whole, can make the caution clear and scientific, and then promote safe medication and TCM modernization and internationalization.

Traditional Chinese medicine (TCM) originated in ancient China has been practiced over thousands of years for treating various symptoms and diseases. However, the molecular mechanisms of TCM in treating these diseases remain unknown. In this study, we employ a systems pharmacology-based approach for connecting GWAS diseases with TCM for potential drug repurposing and repositioning. We studied 102 TCM components and their target genes by analyzing microarray gene expression experiments. We constructed disease-gene networks from 2558 GWAS studies. We applied a systems pharmacology approach to prioritize disease-target genes. Using this bioinformatics approach, we analyzed 14,713 GWAS disease-TCM-target gene pairs and identified 115 disease-gene pairs with q value < 0.2. We validated several of these GWAS disease-TCM-target gene pairs with literature evidence, demonstrating that this computational approach could reveal novel indications for TCM. We also develop TCM-Disease web application to facilitate the traditional Chinese medicine drug repurposing efforts. Systems pharmacology is a promising approach for connecting GWAS diseases with TCM for potential drug repurposing and repositioning. The computational approaches described in this study could be easily expandable to other disease-gene network analysis.

Abstract Traditional Chinese Medicine (TCM) is one of the oldest forms of medicine in the world. There has been a growing interest in TCM in Canada in terms of consumers and also among the research community. To cater for this interest, the Canadian Institute of Chinese Medicinal Research (CICMR) was established in 2004. Since its formation, CICMR has been organizing annual meetings. In 2008, the CICMR meeting, jointly organized with the Ontario Ginseng Innovation Research Centre, was held from October 16th to 19th, in London, Ontario, Canada. The meeting saw a number of participants and speakers from many countries who discussed TCM in a Canadian perspective. The talks and presentations focused on TCM practices in Asia and Canada; analytical techniques for unravelling the science behind TCM; basic and clinical research findings in the areas of cancer and cardiovascular diseases; safety and quality control issues; the regulatory and educational framework of TCM in Canada; and the latest findings in agricultural, chemical, and pharmacological research on ginseng from all over the world. The meeting successfully provided a platform for constructive discussions on TCM practices and research and education in Canada and the world.

Aconitum in traditional Chinese medicine: a valuable drug or an unpredictable risk?

PubMed

Singhuber, Judith; Zhu, Ming; Prinz, Sonja; Kopp, Brigitte

2009-10-29

Aconitum species have been used in China as an essential drug in Traditional Chinese Medicine (TCM) for 2000 years. Reviewing the clinical application of Aconitum, their pharmacological effects, toxicity and detoxifying measures, herb-herb interactions, clinical taboos, famous herbal formulas, traditional and current herbal processing methods based upon a wide range of literature investigations serve as a case study to explore the multidisciplinary implications of botanicals used in TCM. The toxicological risk of improper usage of Aconitum remains very high, especially in countries like China, India and Japan. The toxicity of Aconitum mainly derives from the diester diterpene alkaloids (DDAs) including aconitine (AC), mesaconitine (MA) and hypaconitine (HA). They can be decomposed into less or non-toxic derivatives through Chinese traditional processing methods (Paozhi), which play an essential role in detoxification. Using Paozhi, the three main forms of processed aconite -- yanfuzi, heishunpian and baifupian -- can be obtained (CPCommission, 2005). Moreover, some new processing techniques have been developed in China such as pressure-steaming. The current development of fingerprint assays, in particular HPLC, has set a good basis to conduct an appropriate quality control for TCM crude herbs and their ready-made products. Therefore, a stipulation for a maximum level of DDA content of Aconitum is highly desirable in order to guarantee the clinical safety and its low toxicity in decoctions. Newly developed HPLC methods have made the accurate and simultaneous determination and quantification of DDA content interesting.

Background Despite Hong Kong government's official commitment to the development of traditional Chinese medicine (TCM) over the last ten years, there appears to have been limited progress in public sector initiated career development and postgraduate training (PGT) for public university trained TCM practitioners. Instead, the private TCM sector is expected to play a major role in nurturing the next generation of TCM practitioners. In the present study we evaluated TCM graduates' perspectives on their career prospects and their views regarding PGT. Method Three focus group discussions with 19 local TCM graduates who had worked full time in a clinical setting for fewer than 5 years. Results Graduates were generally uncertain about how to develop their career pathways in Hong Kong with few postgraduate development opportunities; because of this some were planning to leave the profession altogether. Despite their expressed needs, they were dissatisfied with the current quality of local PGT and suggested various ways for improvement including supervised practice-based learning, competency-based training, and accreditation of training with trainee involvement in design and evaluation. In addition they identified educational needs beyond TCM, in particular a better understanding of western medicine and team working so that primary care provision might be more integrated in the future. Conclusion TCM graduates in Hong Kong feel let down by the lack of public PGT opportunities which is hindering career development. To develop a new generation of TCM practitioners with the capacity to provide quality and comprehensive care, a stronger role for the government, including sufficient public funding, in promoting TCM graduates' careers and training development is suggested. Recent British and Australian experiences in prevocational western medicine training reform may serve as a source of references when relevant program for TCM graduates is planned in the future.

Although traditional Chinese medicine (TCM) is known as an integrative part of China's health care system, little is known on the prevalence and determinants of using TCM among the middle-aged and older Chinese population, especially among those with chronic conditions. The nationwide survey data of 17,708 Chinese adults aged 45 and older from the China Health and Retirement Longitudinal Study were used to estimate the prevalence of TCM. SAS SURVEYLOGISTIC procedure was applied to identify factors associated with using TCM. Analysis took into account the complex survey design and nonresponse rate. The prevalence of using TCM was 19.3% (95% CI 18.4%-20.1%) among the overall participants and 24.5% (95% CI 23.4%-25.5%) among those with self-reported chronic conditions. Participants with stroke, cardiovascular disease, and chronic kidney diseases were the most frequent users of TCM to treat their conditions. Age, individual income, and family income were associated with TCM use; however, when further controlling for chronic diseases, these variables became nonsignificant. Besides TCM, 4.4% (3.8%-5.0%) and 4.6% (4.0%-5.2%) of the overall participants and those with chronic conditions, respectively, used other forms of complementary and alternative medicine. The prevalence of using TCM was high among the middle-aged and older Chinese population. The use of TCM was mainly driven by chronic conditions. The main conditions that patients used TCM to treat were stroke, cardiovascular disease, and chronic kidney disease. Copyright © 2015 AMDA – The Society for Post-Acute and Long-Term Care Medicine.

Effect of Bizhongxiao decoction and its dismantled formulae on IL-1 and TNF levels in collagen-induced arthritis in rat synovial joints

PubMed Central

2012-01-01

Background Rheumatoid arthritis (RA), a chronic autoimmune disease, affects sufferers in many different ways. Treatment of this chronic condition is particularly challenging. Traditional Chinese Medicine (TCM) provides alternatives. Bizhongxiao decoction (BZX) is a TCM complex, which has been used clinically for many years to treat RA. The purpose of this study is to compare the effects of BZX decoction and its dismantled formulae on IL-1 and TNF-1 levels in rats with RA, and to elucidate its mechanism of action. Methods Ninety healthy normal female SD rats were randomly divided into six groups: normal (control), model, BZX decoction, and the three dismantled formulae (I: heat-clearing and detoxication, II: dissipating dampness, and III: blood circulation promotion). Apart from the normal (control) group, the rats in each group were injected subcutaneously with bovine type II collagen and complete Freund adjuvant to establish a collagen-induced arthritis model, so that inhibition of foot swelling in the rats by BZX decoction and its dismantled formulae could be observed. Immunohistochemistry was used to assess the levels of the inflammatory cytokines IL-1 and TNF in synovial joints at various time points. Results Twenty-one days after the model was established, the levels of TNF and IL-1 were significantly higher in the model group, BZX decoction group and dismantled formula groups I, II and III than in the normal controls (P < 0.05). The levels of these cytokines were significantly higher in the model group than the BZX decoction or the three dismantled formula groups (P <0.01). At longer times, the TNF and IL-1 levels in model group rose gradually; those in the BZX decoction and dismantled formula groups were gradually reduced. The cytokine levels in the BZX decoction group were lower than in the three dismantled formula groups and continued to decline. Conclusions BZX decoction and the three dismantled formulae examined down-regulated the inflammatory factors IL-1 and TNF in collagen-induced arthritis rat models, but BZX exerted the strongest effect.

Although evidence for their therapeutic efficacy is limited, herbal traditional Chinese medicine (TCM) preparations increasingly gain popularity. In contrast to other herbal products, adverse effects by herbal TCM including liver toxicity were rarely reported. In recent years, more cases were published, providing new clinical challenges. To summarise comprehensively the literature on herbal TCM hepatotoxicity since 2011. PubMed was searched using key words related to TCM, the results were restricted to full English-language publications and abstracts published since 2011. In addition, the database of the National Institutes of Health (NIH) and LiverTox was accessed under the topic 'Drug record: Chinese and other Asian herbal medicines'. Since 2011, new case reports and case series provided evidence for herbal hepatotoxicity by TCM, focusing on nine TCM herbal mixtures and four individual TCM herbs with potential health hazards. These were the TCM products Ban Tu Wan, Chai Hu, Du Huo, Huang Qin, Jia Wei Xia Yao San, Jiguja, Kamishoyosan, Long Dan Xie Gan Tang, Lu Cha, Polygonum multiflorum products, Shan Chi, 'White flood' containing the herbal TCM Wu Zhu Yu and Qian Ceng Ta, and Xiao Chai Hu Tang. Other developments include the establishment of a new and early diagnostic serum marker for hepatotoxicity caused by pyrrolizidine alkaloids, assessed using ultra performance liquid chromatography-mass spectrometry analysis, and new regulatory details to improve herbal TCM product quality and safety. Stringent evaluation of the risk/benefit ratio is essential to protect traditional Chinese medicines users from health hazards including liver injury. © 2014 John Wiley & Sons Ltd.

With western learning spreading throughout the orient, the survival and development of TCM was restrained to a large degree due to the medical administrative policy, educational system and diffusion of western medicine at different social levels. Facing this adversity, the TCM sector complied with the changing times and survived through persistent efforts as well as wide and solid popular foundations, striving actively for the legitimacy status of TCM education and establishing several TCM colleges. During the course of running the colleges, the TCM sector was brave in changing ideas and giving and accepting new knowledge, it explored a comprehensive educational syllabus, which not only promoted the development of TCM education in the Republican period of China, but also laid a foundation for TCM education in the new period.

Numerous people with chronic conditions like to use traditional Chinese medicine (TCM) treatment, or integrated treatment of TCM and Western medicine (WM). Our study explored the associations between multiple chronic conditions (MCC) and TCM use and the use of specific types of TCM therapy among adults in Taiwan. In addition, we explored the TCM use of adults with seven common types of chronic conditions. In our study, a national representative sample in 2005 was used. The Chronic Condition Indicator and the Clinical Classifications System created by the U.S. Agency for Healthcare Research and Quality were used to define the number of chronic conditions of adults. Logistic regressions adjusted for demographic characteristics were used to analyze the associations. The frequency of TCM use among adults with different numbers of chronic conditions was quantified. TCM use for adults with ≥5 chronic conditions (odds ratio [OR] 1.86) was higher than TCM use for adults with 2-4 chronic conditions (OR 1.51) and TCM use for adults with one chronic condition (OR 1.48). The increase in the OR of the use of Chinese herbs and traumatology manipulative therapy according to the number of chronic conditions was not as substantial as that of acupuncture-moxibustion. The frequency of TCM use exhibited an increasing trend with the increase in the number of chronic conditions (p<.001). Among the seven common types of chronic conditions for adults, TCM use for adults with arthropathy (OR 2.01) was the highest. The probability and frequency of TCM use increased as the number of chronic conditions increased. The probability of Chinese herbs use, traumatology manipulative therapy use, and, particularly, acupuncture-moxibustion use increased as the number of chronic conditions increased. We suggest that government policy makers emphasize administering integrated TCM and WM care to people with chronic conditions or MCC.

Traditional Chinese Medicine (TCM) has been practiced over thousands of years in China and other Asian countries for treating various symptoms and diseases. However, the underlying molecular mechanisms of TCM are poorly understood, partly due to the "multi-component, multi-target" nature of TCM. To uncover the molecular mechanisms of TCM, we perform comprehensive gene expression analysis using connectivity map. We interrogated gene expression signatures obtained 102 TCM components using the next generation Connectivity Map (CMap) resource. We performed systematic data mining and analysis on the mechanism of action (MoA) of these TCM components based on the CMap results. We clustered the 102 TCM components into four groups based on their MoAs using next generation CMap resource. We performed gene set enrichment analysis on these components to provide additional supports for explaining these molecular mechanisms. We also provided literature evidence to validate the MoAs identified through this bioinformatics analysis. Finally, we developed the Traditional Chinese Medicine Drug Repurposing Hub (TCM Hub) - a connectivity map resource to facilitate the elucidation of TCM MoA for drug repurposing research. TCMHub is freely available in http://tanlab.ucdenver.edu/TCMHub. Molecular mechanisms of TCM could be uncovered by using gene expression signatures and connectivity map. Through this analysis, we identified many of the TCM components possess diverse MoAs, this may explain the applications of TCM in treating various symptoms and diseases. Copyright © 2018 The Authors.

This project aimed to develop an approach to evaluating information contained in the premodern Traditional Chinese Medicine (TCM) literature that was (1) comprehensive, systematic, and replicable and (2) able to produce quantifiable output that could be used to answer specific research questions in order to identify natural products for clinical and experimental research. The project involved two stages. In stage 1, 14 TCM collections and compendia were evaluated for suitability as sources for searching; 8 of these were compared in detail. The results were published in the Journal of Alternative and Complementary Medicine. Stage 2 developed a text-mining approach for two of these sources. The text-mining approach was developed for Zhong Hua Yi Dian; Encyclopaedia of Traditional Chinese Medicine, 4th edition) and Zhong Yi Fang Ji Da Ci Dian; Great Compendium of Chinese Medical Formulae). This approach developed procedures for search term selection; methods for screening, classifying, and scoring data; procedures for systematic searching and data extraction; data checking procedures; and approaches for analyzing results. Examples are provided for studies of memory impairment and diabetic nephropathy, and issues relating to data interpretation are discussed. This approach to the analysis of large collections of the premodern TCM literature uses widely available sources and provides a text-mining approach that is systematic, replicable, and adaptable to the requirements of the particular project. Researchers can use these methods to explore changes in the names and conceptions of a disease over time, to identify which therapeutic methods have been more or less frequently used in different eras for particular disorders, and to assist in the selection of natural products for research efforts.

Little is known about treatment for patients with medically unexplained symptoms (MUS) in China. This study investigates the treatment expectations and treatment satisfaction of patients with MUS in psychosomatic medicine, biomedicine, and Traditional Chinese Medicine (TCM). In a cross-sectional survey, n = 96 (10.3%) out of 931 participating patients were screened positive for multiple somatoform symptoms. These patients answered questionnaires concerning symptom duration, number of doctor visits, functional impairment, emotional distress, treatment expectations, treatment satisfaction, and empathy in the consultation. The physicians filled in a questionnaire about applied or recommended treatment. Most of the patients from psychosomatic medicine wanted psychotherapy. In TCM, 55% of the patients had already received TCM treatment and most of them wanted to continue TCM treatment. Patients in biomedicine did not express clear expectations; most of them had had no previous treatment. A combination of treatment methods was most prevalent in biomedicine in comparison to psychosomatic medicine and TCM. The outcome from the patients' point of view was significantly better in TCM than in psychosomatic medicine and biomedicine. Psychosomatic medicine's strength was the empathetic physician-patient interaction. From a biopsychosocial perspective, these results suggest that various treatment approaches with various emphases can be effective depending on the patient's complaints, his illness beliefs, and what the physician offers. The results will be verified in a larger multicenter longitudinal study.

Herbal traditional Chinese medicine and its evidence base in gastrointestinal disorders

2015-01-01

Herbal traditional Chinese medicine (TCM) is used to treat several ailments, but its efficiency is poorly documented and hence debated, as opposed to modern medicine commonly providing effective therapies. The aim of this review article is to present a practical reference guide on the role of herbal TCM in managing gastrointestinal disorders, supported by systematic reviews and evidence based trials. A literature search using herbal TCM combined with terms for gastrointestinal disorders in PubMed and the Cochrane database identified publications of herbal TCM trials. Results were analyzed for study type, inclusion criteria, and outcome parameters. Quality of placebo controlled, randomized, double-blind clinical trials was poor, mostly neglecting stringent evidence based diagnostic and therapeutic criteria. Accordingly, appropriate Cochrane reviews and meta-analyses were limited and failed to support valid, clinically relevant evidence based efficiency of herbal TCM in gastrointestinal diseases, including gastroesophageal reflux disease, gastric or duodenal ulcer, dyspepsia, irritable bowel syndrome, ulcerative colitis, and Crohn’s disease. In conclusion, the use of herbal TCM to treat various diseases has an interesting philosophical background with a long history, but it received increasing skepticism due to the lack of evidence based efficiency as shown by high quality trials; this has now been summarized for gastrointestinal disorders, with TCM not recommended for most gastrointestinal diseases. Future studies should focus on placebo controlled, randomized, double-blind clinical trials, herbal product quality and standard criteria for diagnosis, treatment, outcome, and assessment of adverse herb reactions. This approach will provide figures of risk/benefit profiles that hopefully are positive for at least some treatment modalities of herbal TCM. Proponents of modern herbal TCM best face these promising challenges of pragmatic modern medicine by bridging the gap between the two medicinal cultures. PMID:25914456

Traditional Chinese Medicine (TCM), including Traditional Chinese Medicine drugs (TCM drugs), has been playing a very important role in health protection and disease control for thousands of years in China. Relying on natural products, mainly of herbal origin, used either as raw materials for decoction, as prepared herbal medicines or as formulated traditional medicines, TCM is still widely accepted by Chinese people, especially for chronic diseases treatment. This extensive use warrants safety measures and so TCM drug safety monitoring and risk management are becoming increasingly important tasks for the Chinese State Food and Drug Administration (SFDA). The Adverse Drug Reaction (ADR) monitoring system in China was established both for western and TCM drugs in 1989 as a voluntary reporting system with a National Center collecting and compiling reports. Serious or multi-case reports on individual TCM drug or formulated products are detailed in the Chinese ADR Information Bulletin to inform the public and Drug Administrative authorities for risk management. About 10-15% of the ADR reports received by the National Center are related to TCM drugs and mainly pertaining to the formulated products. In certain cases, the suspension of a particular TCM preparation is decided by SFDA China. The model of safety monitoring and risk management of TCM drugs is still under exploration. Indeed, the characteristics and risk factors associated with these drugs require both proper understanding and control of the risk by strengthening standardization of clinical applications, basic science research, quality control in manufacturing, exploration of the actives monitoring methodology and enhancement of international communication and cooperation.

As an important representative of modern Chinese medicine, traditional Chinese medicine (TCM) injzection has become an indispensable part of the Chinese medicine industry. However, its development is now restricted by the bottleneck of insufficient core competitiveness, low-level research and production, even injection quality and the safe use are not guaranteed. Thus, it is urgent to reevaluate post-marketing TCM injection generally and to make secondary development. Under current circumstances, taking major brands which have good clinical and market foundation, as well as research value, as the main subject of cultivation and evaluation is an important approach to innovative development of TCM injection industry. Unlike oral proprietary Chinese medicine, the cultivatation of major brands of TCM injection needs higher technical support, quality standards and more timely feedback. Therefore, a post-market integral evaluation system adaptive to TCM injection is required. This article discussed some key points on the construction of a post-market integral evaluation system of TCM injection in three levels： optimizing evaluation methods, building synergistic innovation platforms which combine the medical research institutions and pharmaceutical enterprises, and finally constructing the integral evaluation system. A "five to one" structure has been proposed to enhance TCM injection effectiveness, safety and adaptability on the whole, which are from the following aspects： mechanism research, clinical evidence validation, literature information mining, sustainable development of resources and industrialization operation.

Traditional Chinese medicine (TCM) has remained an integral part of Chinese culture and society for thousands of years. In Taiwan TCM is a recognized element of its National Health Insurance Scheme. However, there is no knowledge about how TCM is accessed by foreign workers from a non-Asian cultural background. The objectives of this study were to investigate the prevalence and patterns of TCM use among non-Asian white-collar workers living in Taiwan, and examine factors likely to influence their use of TCM. This study applied a cross-sectional survey design. A total of 207 white-collar foreign workers of a non-Asian background currently holding National Health Insurance cards who had lived in Taiwan for 4 months or more participated in this study. The prevalence of TCM use was 45%. The most frequently used therapies were traditional Chinese herbs/medicine and acupuncture. Factors indicating the likelihood of TCM usage were age 31-40 years, visit to an allopathic medical doctor in the last year, ability to read Chinese, having a friend or family member available to assist in the use of TCM, and access to information about TCM services available in Taiwan. Utilization of TCM by people of a non-Asian background living in Taiwan appears to be most influenced by enabling factors including language ability, access to information, and informal reference persons.

Traditional Chinese Medicine or Traditional Complementary Medicine (TCM) is commonly used in our culture. There are several concerns regarding its use in patients undergoing conventional treatments for breast cancer. In this study, we aimed to evaluate the prevalence and pattern of TCM use among our breast cancer patients, and to identify patients who were most likely to choose TCM. A total of 300 patients on active follow-up with Breast Service at Tan Tock Seng Hospital were interviewed using a structured questionnaire. A total of 35% (104 of 296) of patients reported using TCM. The majority of the patients were introduced to TCM by family and friends following the diagnosis of breast cancer. All except 3 patients continued with recommended conventional therapy although most did not inform their clinicians of TCM use. None of the patients reported any serious adverse events and 75% of them perceived a benefit from TCM use. Younger patients and those of Chinese ethnicity were more likely to use TCM (P <0.01 and P = 0.03 respectively). There was no significant difference in the dialect group, religious beliefs and educational level between the 2 groups (P >0.05). TCM use is common among our breast cancer patients, particularly the younger women. However, most patients do not inform their clinicians of TCM use while on recommended conventional therapies. It is therefore important for clinicians to initiate discussions regarding TCM use in order to be aware of potential unwanted drug interactions.

Chinese herbal prescriptions for osteoarthritis in Taiwan: analysis of national health insurance dataset

2014-01-01

Background Chinese herbal medicine (CHM) has been commonly used for treating osteoarthritis in Asia for centuries. This study aimed to conduct a large-scale pharmaco-epidemiologic study and evaluate the frequency and patterns of CHM used in treating osteoarthritis in Taiwan. Methods A complete database (total 22,520,776 beneficiaries) of traditional Chinese medicine (TCM) outpatient claims offered by the National Health Insurance program in Taiwan for the year 2002 was employed for this research. Patients with osteoarthritis were identified according to the diagnostic code of the International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and an association rule was applied to evaluate the co-prescription of CHM for treating osteoarthritis. Results There were 20,059 subjects who visited TCM clinics for osteoarthritis and received a total of 32,050 CHM prescriptions. Subjects between 40 and 49 years of age comprised the largest number of those treated (19.2%), followed by 50-59 years (18.8%) and 60-69 years group (18.2%). In addition, female subjects used CHMs for osteoarthritis more frequently than male subjects (female: male = 1.89: l). There was an average of 5.2 items prescribed in the form of either an individual Chinese herb or formula in a single CHM prescription for osteoarthritis. Du-zhong (Eucommia bark) was the most commonly prescribed Chinese single herb, while Du-huo-ji-sheng-tang was the most commonly prescribed Chinese herbal formula for osteoarthritis. According to the association rule, the most commonly prescribed formula was Du-huo-ji-sheng-tang plus Shen-tong-zhu-yu-tang, and the most commonly prescribed triple-drug combination was Du-huo-ji-sheng-tang, Gu-sui-pu (Drynaria fortune (Kunze) J. Sm.), and Xu-Duan (Himalaya teasel). Nevertheless, further clinical trials are needed to evaluate the efficacy and safety of these CHMs for treating osteoarthritis. Conclusions This study conducted a large scale pharmaco-epidemiology survey of Chinese herbal medicine use in OA patients by analyzing the NHIRD in Taiwan in year 2002. PMID:24606767

2016-01-01

The increasing acceptance of traditional Chinese medicine (TCM) worldwide has highlighted the importance of ensuring the provision of high-quality TCM clinical education. This clinical training should be partly guided by a robust assessment of patient data outcomes in TCM teaching clinics. We undertook a comprehensive literature review to examine the data evaluation in TCM teaching clinics outside China and its implications for TCM education. Literature was retrieved via MEDLINE (from 1946 to January 2015), EMBASE (from 1980 to February 2015), and Google Scholar for studies conducted outside China. The search was restricted to English articles reporting empirical findings related to the assessments of patient data in TCM teaching clinics, with implications for TCM education in countries other than China. Only seven articles from six studies met the inclusion criteria. The characteristics and main symptoms of patients who received any TCM treatment in the context of teaching clinics among all included studies were similar. Symptom relief as well as a high level of patient satisfaction with TCM treatment were found in TCM teaching clinics. Conventional healthcare providers and other complementary practitioners were not the main source of referral to TCM practitioners but rather patients׳ friends/relatives. Patients received acupuncture treatment more frequently than treatments utilizing Chinese herbal medicine in teaching clinics. A standardized and consistent framework for patient records within TCM teaching clinics is currently lacking. There was no robust study which "translated" TCM clinic data evaluation findings into implications for TCM education and clinical training. Recognizing that TCM evolves over time and its practice varies in different settings, there is an urgent need to conduct large-scale, rigorous evaluations of TCM clinic data to address the findings of our review, with the purpose of better informing TCM education and clinical training in countries beyond China. Expansions for scientific efforts supporting TCM education are essential to ensure that qualified TCM practitioners are able to provide safe, efficacious, and cost-effective TCM treatment modalities.

Traditional Chinese medicine (TCM), which is fundamentally different from Western medicine, has been widely investigated using various approaches. Cellular- or molecular-based imaging has been used to investigate and illuminate the various challenges identified and progress made using therapeutic methods in TCM. Insight into the processes of TCM at the cellular and molecular changes and the ability to image these processes will enhance our understanding of various diseases of TCM and will provide new tools to diagnose and treat patients. Various TCM therapies including herbs and formulations, acupuncture and moxibustion, massage, Gua Sha, and diet therapy have been analyzed using positron emission tomography, single photon emission computed tomography, functional magnetic resonance imaging and ultrasound and optical imaging. These imaging tools have kept pace with developments in molecular biology, nuclear medicine, and computer technology. We provide an overview of recent developments in demystifying ancient knowledge - like the power of energy flow and blood flow meridians, and serial naturopathies - which are essential to visually and vividly recognize the body using modern technology. In TCM, treatment can be individualized in a holistic or systematic view that is consistent with molecular imaging technologies. Future studies might include using molecular imaging in conjunction with TCM to easily diagnose or monitor patients naturally and noninvasively. Copyright © 2011 Elsevier Ireland Ltd.

2015-01-01

As a complementary and alternative medicine in medical field, traditional Chinese medicine (TCM) has drawn great attention in the domestic field and overseas. In practice, TCM provides a quite distinct methodology to patient diagnosis and treatment compared to western medicine (WM). Syndrome (ZHENG or pattern) is differentiated by a set of symptoms and signs examined from an individual by four main diagnostic methods: inspection, auscultation and olfaction, interrogation, and palpation which reflects the pathological and physiological changes of disease occurrence and development. Patient classification is to divide patients into several classes based on different criteria. In this paper, from the machine learning perspective, a survey on patient classification issue will be summarized on three major aspects of TCM: sign classification, syndrome differentiation, and disease classification. With the consideration of different diagnostic data analyzed by different computational methods, we present the overview for four subfields of TCM diagnosis, respectively. For each subfield, we design a rectangular reference list with applications in the horizontal direction and machine learning algorithms in the longitudinal direction. According to the current development of objective TCM diagnosis for patient classification, a discussion of the research issues around machine learning techniques with applications to TCM diagnosis is given to facilitate the further research for TCM patient classification.

GP-TCM is the 1st EU-funded Coordination Action consortium dedicated to traditional Chinese medicine (TCM) research. This paper aims to summarise the objectives, structure and activities of the consortium and introduces the position of the consortium regarding good practice, priorities, challenges and opportunities in TCM research. Serving as the introductory paper for the GP-TCM Journal of Ethnopharmacology special issue, this paper describes the roadmap of this special issue and reports how the main outputs of the ten GP-TCM work packages are integrated, and have led to consortium-wide conclusions. Literature studies, opinion polls and discussions among consortium members and stakeholders. By January 2012, through 3 years of team building, the GP-TCM consortium had grown into a large collaborative network involving ∼200 scientists from 24 countries and 107 institutions. Consortium members had worked closely to address good practice issues related to various aspects of Chinese herbal medicine (CHM) and acupuncture research, the focus of this Journal of Ethnopharmacology special issue, leading to state-of-the-art reports, guidelines and consensus on the application of omics technologies in TCM research. In addition, through an online survey open to GP-TCM members and non-members, we polled opinions on grand priorities, challenges and opportunities in TCM research. Based on the poll, although consortium members and non-members had diverse opinions on the major challenges in the field, both groups agreed that high-quality efficacy/effectiveness and mechanistic studies are grand priorities and that the TCM legacy in general and its management of chronic diseases in particular represent grand opportunities. Consortium members cast their votes of confidence in omics and systems biology approaches to TCM research and believed that quality and pharmacovigilance of TCM products are not only grand priorities, but also grand challenges. Non-members, however, gave priority to integrative medicine, concerned on the impact of regulation of TCM practitioners and emphasised intersectoral collaborations in funding TCM research, especially clinical trials. The GP-TCM consortium made great efforts to address some fundamental issues in TCM research, including developing guidelines, as well as identifying priorities, challenges and opportunities. These consortium guidelines and consensus will need dissemination, validation and further development through continued interregional, interdisciplinary and intersectoral collaborations. To promote this, a new consortium, known as the GP-TCM Research Association, is being established to succeed the 3-year fixed term FP7 GP-TCM consortium and will be officially launched at the Final GP-TCM Congress in Leiden, the Netherlands, in April 2012.

Traditional Chinese medicine (TCM) is widely used among Chinese cancer patients. However, little is known about Chinese patients' expectations and barriers toward using TCM for cancer. We conducted a cross-sectional survey within a patient-support group, the Beijing Anti-Cancer Association. We measured the outcome, Chinese cancer survivors' expectations and barriers toward TCM utilization, using a modified version of ABCAM (Attitudes and Beliefs towards Complementary and Alternative Medicine), the ABTCM (Attitudes and Beliefs towards Traditional Chinese Medicine). We used multivariate models to evaluate the impact of socioeconomic status and clinical factors on their expectations and barriers (including treatment concerns and logistical challenges domain) toward TCM. Among 590 participants, most patients expected TCM to boost their immune system (96%), improve their physical health (96%), and reduce symptoms (94%). Many had logistical challenges (difficulty decocting herbs (58%) and finding a good TCM physician (55%)). A few were concerned that TCM might interfere with conventional treatments (7.6%), and that many TCM treatments are not based on scientific research (9.1%). In the multivariable regression model, age ≤60 years was independently associated with higher expectation score ( P = .031). Age ≤60 years (coefficient 5.0, P = .003) and localized disease (coefficient 9.5, P = .001) were both associated with higher treatment concerns. Active employment status (coefficient 9.0, P = .008) and localized disease (coefficient 7.5, P = .030) were related to more logistical challenges. Age and cancer stage were related to Chinese cancer patients' perceived expectations and barriers toward TCM use. Understanding these attitudes is important for reshaping the role that TCM plays in China's patient-centered comprehensive cancer care model.

2016-06-07

This paper aims to investigate the development trend of traditional Chinese medicine (TCM) hospitals in China and explore their medical service innovations, with special reference to the changing co-existence with western medicine (WM) at TCM hospitals. Quantitative data at macro level was collected from official databases of China Health Statistical Yearbook and Extracts of Traditional Chinese Medicine Statistics. Qualitative data at micro level was gathered through interviews and second-hand material collection at two of the top-level TCM hospitals. In both outpatient and inpatient sectors of TCM hospitals, drug fees accounted for the biggest part of hospital revenue. Application of WM medical exanimation increased in both outpatient and inpatient services. Even though the demand for WM drugs was much higher in inpatient care, TCM drugs was the winner in the outpatient. Also qualitative evidence showed that TCM dominated the outpatient hospital service with WM incorporated in the assisting role. However, it was in the inpatient medical care that WM prevailed over TCM which was mostly applied to the rehabilitation of patients. By drawing on WM while keeping it active in supporting and strengthening the TCM operation in the TCM hospital, the current system accommodates the overriding objective which is for TCM to evolve into a fully informed and more viable medical field. © 2017 The Author(s); Published by Kerman University of Medical Sciences.

2017-01-01

Background Traditional Chinese Medicine (TCM) includes both herbal remedies and non-herbal practices. Chinese cancer patients are at particularly high risk for herb-drug interactions. Providers, both primary care physicians (PCPs) and oncologists, frequently do not ask patients about TCM use, with potentially dangerous consequences. Objective This study describes an assessment of TCM use while undergoing conventional cancer treatment, among a cohort of Chinese immigrant cancer patients in New York City. Design and Participants The Immigrant Health and Cancer Disparities Service at Memorial Sloan-Kettering Cancer Center (MSKCC) assists underserved cancer patients through a patient navigation program, the Cancer Portal Project. Six questions related to TCM are included in the existing Portal Needs Assessment Intake. Mandarin or Cantonese speaking Portal patients enrolled between January 2010 and May 2012 were surveyed. Results 109 Chinese-speaking patients were enrolled in Portal during the study period. 46 completed the TCM questions. 96% preferred to speak Mandarin, Cantonese, or Fujianese in the healthcare setting. 39% (n=18) of the 46 participants reported using TCM since being diagnosed with cancer. Nearly all (n=16) who used TCM reported using herbal medicines. Ten TCM users did not describe sharing their use with Western doctors. Eight (44%) of TCM users reported concurrently using TCM and conventional cancer treatment. Conclusions Larger scale studies should further explore the concurrent use of TCM and conventional cancer treatment in this unique population. Future research should also address patient-provider communication related to concurrent use of TCM and cancer treatment. This is also an important area of education for both patients and providers.

Thirty-nine percent (n = 18) of the 46 participants reported using TCM since being diagnosed with cancer. Nearly all (n = 16) who used TCM reported using herbal medicines. Ten TCM users did not describe sharing their use with Western doctors. Eight (44%) of TCM users reported concurrently using TCM and conventional cancer treatment. Larger scale studies should further explore the concurrent use of TCM and conventional cancer treatment in this unique population. Future research should also address patient-provider communication related to the concurrent use of TCM and cancer treatment. This is also an important area of education for both patients and providers.

Traditional Chinese Medicine (TCM), with a history of thousands of years of clinical practice, is gaining more and more attention and application worldwide. And TCM-based new drug development, especially for the treatment of complex diseases is promising. However, owing to the TCM's diverse ingredients and their complex interaction with human body, it is still quite difficult to uncover its molecular mechanism, which greatly hinders the TCM modernization and internationalization. Here we developed the first online Bioinformatics Analysis Tool for Molecular mechANism of TCM (BATMAN-TCM). Its main functions include 1) TCM ingredients' target prediction; 2) functional analyses of targets including biological pathway, Gene Ontology functional term and disease enrichment analyses; 3) the visualization of ingredient-target-pathway/disease association network and KEGG biological pathway with highlighted targets; 4) comparison analysis of multiple TCMs. Finally, we applied BATMAN-TCM to Qishen Yiqi dripping Pill (QSYQ) and combined with subsequent experimental validation to reveal the functions of renin-angiotensin system responsible for QSYQ's cardioprotective effects for the first time. BATMAN-TCM will contribute to the understanding of the "multi-component, multi-target and multi-pathway" combinational therapeutic mechanism of TCM, and provide valuable clues for subsequent experimental validation, accelerating the elucidation of TCM's molecular mechanism. BATMAN-TCM is available at http://bionet.ncpsb.org/batman-tcm.

Traditional Chinese medicine (TCM) has been long practiced and is becoming ever more widely recognized as providing curative and/or healing treatments for a number of diseases and physiological conditions. This paper posits that herbal medicines used in TCM treatments may act through hormetic dose-response mechanisms. It is proposed that the stimulatory (i.e., low dose) and inhibitory (i.e., high dose) components of the hormetic dose response correspond to respective "regulating" and "curing" aspects of TCM herbal treatments. Specifically, the "regulating" functions promote adaptive or preventive responses, while "curing" treatments alleviate the clinical symptoms. Patterns of hormetic responses are described, and the applicability of these processes to herbal medicines of TCM are explicated. It is noted that a research agenda aimed at elucidating these mechanisms and patterns would be expansive and complex. However, we argue its value, in that hormesis may afford something akin to a Rosetta Stone with which to interpret, translate, and explain TCM herbology in ways that are aligned with biomedical perspectives that could enable a more integrative approach to medicine.

Incorporating "-omics" studies with environmental interactions could help elucidate the biological mechanisms responsible for Traditional Chinese Medicine (TCM) patterns. Based on the authors' own experiences, this review outlines a model of an ideal combination of "-omics" biomarkers, environmental factors, and TCM pattern classifications; provides a narrative review of the relevant genetic and TCM studies; and lists several successful integrative examples. Two integration tools are briefly introduced. The first is the integration of modern devices into objective diagnostic methods of TCM patterning, which would improve current clinical decision-making and practice. The second is the use of biobanks and data platforms, which could broadly support biological and medical research. Such efforts will transform current medical management and accelerate the progression of precision medicine.

Traditional Chinese medicine (TCM) formula Bi-Qi capsule (Bi-Qi) is a commonly prescribed drug to treat rheumatoid arthritis (RA). However, the mechanism of Bi-Qi-mediated amelioration of RA pathogenesis is still a mystery. Collagen induced arthritis (CIA) in rats is an established model that shares many similarities with RA in humans. In this study we investigated the effect of Bi-Qi on the pathogenesis of CIA in rats. CIA was developed in Sprague-Dawley (S.D) rats (n = 60, female) and used as a model resembling RA in humans. Rats were treated with a high or moderate dose of Bi-Qi, or methotrexate (MTX). Effects of the treatment on local joint and systemic inflammation, synovial hyperplasia, cartilage destruction, and other main features in the pathogenesis of CIA were analyzed. Inflamed and swollen ankles and joints were observed in arthritic rats, while Bi-Qi or MTX treatment alleviated these symptoms. Only the Bi-Qi moderate dose decreased RA-induced serum levels of tumor necrosis factor-alpha (TNF-α). Both Bi-Qi and MTX reduced the interleukin (IL)-18 serum level. Protein levels of cartilage oligomeric matrix protein and osteopontin in serum, synovium, and cartilage were elevated in arthritic rats, while Bi-Qi alleviated these effects. Synovial hyperplasia, inflammatory cell infiltration in synovium and a high degree of cartilage degradation was observed in RA, and Bi-Qi or MTX alleviated this effect. Bi-Qi at the moderate dose was the most effective in mitigating CIA-related clinical complications. Our findings showed that Bi-Qi alleviates CIA-induced inflammation, synovial hyperplasia, cartilage destruction, and the other main features in the pathogenesis of CIA. This provides fundamental evidence for the anti-arthritic properties of Bi-Qi and corroborates the use of Bi-Qi TCM formula for the treatment of RA.

Compared with the therapeutic effects of established medicinal drugs, it is often considered that natural product-derived drugs are of a more benign nature in side-effects, which has made natural medicines become a popular form of therapy. Traditional Chinese medicine (TCM) is generally considered as being natural and harmless. TCM has been paid much more attention than before and widely used for the treatment nowadays. However, with the increasing cases of adverse drug reactions (ADRs), the ADRs induced by TCM are becoming more widely recognized. Some ADRs are sometimes even life-threatening. This article reviews literatures on ADRs induced by TCM which was published in the past 10 years. A total of 3122 cases including complete data are selected for the present analysis. From the data of the 3122 cases, statistics is carried out to the distribution of administration routes and time of the occurrence of ADRs, the prognosis of ADRs, sex and age factors, types and clinical symptoms of ADRs, and drugs involved in ADRs. In addition, occurrence and influencing factors of TCM-induced diseases are also analysed, which includes spices confusion, processing drugs improperly, toxic components, long-term medication, improper concerted application, interaction of TCM and Western medicine. It is concluded that the efficacy and toxicity of TCM, often using the compound prescription involving various plants and animals, resulted from a variety of chemical constituents, which lead to a comprehensive response in the human body. The ‘toxicity’ of TCM should be correctly recognized and reasonably utilized. PMID:20233209

This large-scale survey aimed to evaluate frequencies and patterns of Chinese herbal medicine (CHM) used for Sjögren's syndrome (SS) in Taiwan by analyzing the National Health Insurance Research Database (NHIRD) for cases in which CHM was used as an alternative therapy to Western medicine for improving patients' discomforts. We analyzed cases of SS principal diagnosis (ICD-9:710.2) with a catastrophic illness certificate (CIC) in traditional Chinese medicine (TCM) outpatient clinics from three cohorts of the Longitudinal Health Insurance Database (LHID) in the NHIRD between 2002 and 2011. CHM prescription patterns for SS were evaluated from claimed visitation files and corresponding prescription files. There were 15,914 SS patients with CIC (SS/CIC), and we found only 130 SS/CIC cases visiting TCM clinics in LHID2000, 133 in LHID2005, and 126 in LHID2010. After removing duplicate data, 366 SS/CIC and 4,867 visits were analyzed. The 50–59 year age group showed the highest ratio (29.51%) in both women and men. “Qi-Ju-Di-Huang-Wan” and “Xuan-Shen” (Scrophularia ningpoensis Hemsl.) was the most commonly used formula and single herb, respectively. “Qi-Ju-Di-Huang-Wan, Gan-Lu-Yin, Xuan-Shen, Mai-Men-Dong (Ophiopogon japonicus (L. f.) Ker-Gawl.), and Sheng-Di-Huang (raw Rehmannia glutinosa Libosch)” were the core pattern prescriptions in treating SS/CIC. PMID:25923413

Traditional Chinese medicine (TCM) has been a major part of healthcare in China, and has extensively affected medicine and healthcare in surrounding countries over a long period of time. In the fight against cancer, certain anticancer remedies using herbs or herbal formulas derived from TCM have been developed for the management of malignancies. Furthermore, there are clinical trials registered for the use of herbal remedies in cancer management. Herbal medicine has been used as part of combined therapies to reduce the side-effects of chemotherapy, including bone marrow suppression, nausea and vomiting. Herbal remedies have also been used as chemopreventive therapies to treat precancerous conditions in order to reduce the incidence of cancer in high-risk populations. Emerging evidence has revealed that herbal remedies can regulate the proliferation, apoptosis, adhesion and migration of cancer cells. In addition to this direct effect upon cancer cells, a number of herbal remedies have been identified to suppress angiogenesis and therefore reduce tumour growth. The inhibition of tumour growth may also be due to modifications of the host immune system by the herbal treatment. However, the precise mechanisms underlying the therapeutic effects of herbal remedies remain poorly understood and are yet to be fully elucidated. The present study aims to summarize the current literature and clinical trial results of herbal remedies for cancer treatment, with a particular focus on the recent findings and development of the Yangzheng Xiaoji capsule.

Nanotechnology is an advanced scientific technique in the 21st century and diabetes mellitus (DM) is a commonly seen chronic disease, which seriously threatens the health of human beings. By analyzing the relationship between nanotechnology and biological medicine, nanotechnology and traditional Chinese medicine (TCM) and the advances and the existing problems of TCM diagnosing and treating DM, the application of nanotechnological methods for the mechanism research on TCM diagnosis and treatment of DM was discussed. It is indicated that nanotechnology is one of the fastest developmental, the most potential and the far-reaching high and new technologies in current world, and it greatly promotes the development of biological medicine and TCM. With the application of nanotechnology of medical diagnostics and medical materials, it will make the development of TCM possess an unprecedented field, which consequently could integrate the macroscopical and microscopical syndrome differentiation. It's pointed out that breakthrough will be achieved from the research of the administration route, the improvement of medical biological availability and the selection of the acupoint prescriptions on mechanism research on TCM for the diagnosis and treatment of diabetes mellitus.

Studies on traditional Chinese medicine (TCM), like those of other systems of traditional medicine (TM), are very variable in their quality, content and focus, resulting in issues around their acceptability to the global scientific community. In an attempt to address these issues, an European Union funded FP7 consortium, composed of both Chinese and European scientists and named "Good practice in traditional Chinese medicine" (GP-TCM), has devised a series of guidelines and technical notes to facilitate good practice in collecting, assessing and publishing TCM literature as well as highlighting the scope of information that should be in future publications on TMs. This paper summarises these guidelines, together with what has been learned through GP-TCM collaborations, focusing on some common problems and proposing solutions. The recommendations also provide a template for the evaluation of other types of traditional medicine such as Ayurveda, Kampo and Unani. GP-TCM provided a means by which experts in different areas relating to TCM were able to collaborate in forming a literature review good practice panel which operated through e-mail exchanges, teleconferences and focused discussions at annual meetings. The panel involved coordinators and representatives of each GP-TCM work package (WP) with the latter managing the testing and refining of such guidelines within the context of their respective WPs and providing feedback. A Good Practice Handbook for Scientific Publications on TCM was drafted during the three years of the consortium, showing the value of such networks. A "deliverable - central questions - labour division" model had been established to guide the literature evaluation studies of each WP. The model investigated various scoring systems and their ability to provide consistent and reliable semi-quantitative assessments of the literature, notably in respect of the botanical ingredients involved and the scientific quality of the work described. This resulted in the compilation of (i) a robust scoring system and (ii) a set of minimum standards for publishing in the herbal medicines field, based on an analysis of the main problems identified in published TCM literature. Good quality, peer-reviewed literature is crucial in maintaining the integrity and the reputation of the herbal scientific community and promoting good research in TCM. These guidelines provide a clear starting point for this important endeavour. They also provide a platform for adaptation, as appropriate, to other systems of traditional medicine.

Multi-herb prescriptions of traditional Chinese medicine (TCM) often include special herb-pairs for mutual enhancement, assistance, and restraint. These TCM herb-pairs have been assembled and interpreted based on traditionally defined herbal properties (TCM-HPs) without knowledge of mechanism of their assumed synergy. While these mechanisms are yet to be determined, properties of TCM herb-pairs can be investigated to determine if they exhibit features consistent with their claimed unique synergistic combinations. We analyzed distribution patterns of TCM-HPs of TCM herb-pairs to detect signs indicative of possible synergy and used artificial intelligence (AI) methods to examine whether combination of their TCM-HPs are distinguishable from those of non-TCM herb-pairs assembled by random combinations and by modification of known TCM herb-pairs. Patterns of the majority of 394 known TCM herb-pairs were found to exhibit signs of herb-pair correlation. Three AI systems, trained and tested by using 394 TCM herb-pairs and 2470 non-TCM herb-pairs, correctly classified 72.1-87.9% of TCM herb-pairs and 91.6-97.6% of the non-TCM herb-pairs. The best AI system predicted 96.3% of the 27 known non-TCM herb-pairs and 99.7% of the other 1,065,100 possible herb-pairs as non-TCM herb-pairs. Our studies suggest that TCM-HPs of known TCM herb-pairs contain features distinguishable from those of non-TCM herb-pairs consistent with their claimed synergistic or modulating combinations.

Background Traditional Chinese medicine (TCM) has remained an integral part of Chinese culture and society for thousands of years. In Taiwan TCM is a recognized element of its National Health Insurance Scheme. However, there is no knowledge about how TCM is accessed by foreign workers from a non-Asian cultural background. The objectives of this study were to investigate the prevalence and patterns of TCM use among non-Asian white-collar workers living in Taiwan, and examine factors likely to influence their use of TCM. Methods This study applied a cross-sectional survey design. A total of 207 white-collar foreign workers of a non-Asian background currently holding National Health Insurance cards who had lived in Taiwan for 4 months or more participated in this study. Results The prevalence of TCM use was 45%. The most frequently used therapies were traditional Chinese herbs/medicine and acupuncture. Factors indicating the likelihood of TCM usage were age 31–40 years, visit to an allopathic medical doctor in the last year, ability to read Chinese, having a friend or family member available to assist in the use of TCM, and access to information about TCM services available in Taiwan. Conclusion Utilization of TCM by people of a non-Asian background living in Taiwan appears to be most influenced by enabling factors including language ability, access to information, and informal reference persons.

Traditional and Complementary Medicines (TCM) are widely used worldwide, and many of them have the potential to cause toxicity, interaction with conventional medications and non-adherence to prescribed medications due to patients' preference for the TCM use. However, information regarding their use among patients seeking care at emergency departments (ED) of a healthcare facility is limited. The study aimed to evaluate the TCM use among patients attending the ED of a teaching hospital in Malaysia. A sub-analysis of data from a prevalence study of medication-related visits among patients at the ED of Hospital Universiti Sains Malaysia was conducted. The study took place over a period of six weeks from December 2014 to January 2015 involving 434 eligible patients. Data on demography, conventional medication, and TCM uses were collected from patient interview and the medical folders. Among this cohort, 66 patients (15.2%, 95%CI 12.0, 19.0) reported concurrent TCM use. Sixteen (24.2%) of the TCM users were using more than one (1) type of TCM, and 17 (25.8%) came to the ED for medication-related reasons. Traditional Malay Medicine (TMM) was the most frequently used TCM by the patients. Five patients (7.6%) sought treatment at the ED for medical problems related to use of TCM. Patients seeking medical care at the ED may be currently using TCM. ED-physicians should be aware of these therapies and should always ask patients about the TCM use. Copyright © 2018 Elsevier Ltd.

A case is presented to illustrate a potential effect of Chinese herbal medicine (CHM) formulas in treating chemotherapy-induced cardiotoxicity. An 18-year-old adolescent male with refractory acute lymphoblastic leukemia (ALL) had experienced anthracycline-induced congestive heart failure (CHF) for 3 weeks. Under intensive care with conventional therapy, the patient still had exercise intolerance and depended on supplemental oxygen all day. Therefore, he consented to treatment with traditional Chinese medicine (TCM) for alternative therapy. This patient was treated with modified Zhi Gan Cao Tang (ZGCT), three times a day for 2 months. After 6 days of CHM treatment, the patient could tolerate daily activity without supplemental oxygen. After 2 months of CHM treatment, the follow-up chest X-ray showed great improvements in pulmonary edema and cardiomegaly. In this case, anthracycline-induced cardiotoxicity resolved slowly following the administration of modified ZGCT. It is suggested that the CHM formula has a protective effect on the progression of CHF secondary to the use of anthracyclines in pediatric cancer. Further studies to determine the mechanism and clinical trials are warranted. Copyright © 2015 Elsevier Ltd. All rights reserved.

Despite the widespread use of traditional Chinese medicine (TCM) in clinical settings, proving its effectiveness via scientific trials is still a challenge. TCM views the human body as a complex dynamical system, and focuses on the balance of the human body, both internally and with its external environment. Such fundamental concepts require investigations using system-level quantification approaches, which are beyond conventional reductionism. Only methods that quantify dynamical complexity can bring new insights into the evaluation of TCM. In a previous article, we briefly introduced the potential value of Multiscale Entropy (MSE) analysis in TCM. This article aims to explain the existing challenges in TCM quantification, to introduce the consistency of dynamical complexity theories and TCM theories, and to inspire future system-level research on health and disease.

The whole process quality control and management of traditional Chinese medicine (TCM) decoction pieces is a system engineering, involving the base environment, seeds and seedlings, harvesting, processing and other multiple steps, so the accurate identification of factors in TCM production process that may induce the quality risk, as well as reasonable quality control measures are very important. At present, the concept of quality risk is mainly concentrated in the aspects of management and regulations, etc. There is no comprehensive analysis on possible risks in the quality control process of TCM decoction pieces, or analysis summary of effective quality control schemes. A whole process quality control and management system for TCM decoction pieces based on TCM quality tree was proposed in this study. This system effectively combined the process analysis method of TCM quality tree with the quality risk management, and can help managers to make real-time decisions while realizing the whole process quality control of TCM. By providing personalized web interface, this system can realize user-oriented information feedback, and was convenient for users to predict, evaluate and control the quality of TCM. In the application process, the whole process quality control and management system of the TCM decoction pieces can identify the related quality factors such as base environment, cultivation and pieces processing, extend and modify the existing scientific workflow according to their own production conditions, and provide different enterprises with their own quality systems, to achieve the personalized service. As a new quality management model, this paper can provide reference for improving the quality of Chinese medicine production and quality standardization.

Traditional Chinese medicine (TCM) has been demonstrated to have potent cytotoxic activity against certain malignant tumors. Ionizing radiation (IR) is one of the most effective methods used in the clinical treatment of cancer. The drawback of a single formula is that it limits the treatment efficacy for cancer, while comprehensive strategies require additional theoretical support. However, a combination of different antitumor treatment modalities is advantageous in restricting the non-specific toxicity often observed with an extremely high dose of a single regimen. The induction of apoptotic cell death is a significant process in tumor cells following radiotherapy or chemotherapy, and resistance to these treatments has been linked to a low propensity for apoptosis. Autophagy is a response of cancer cells to IR or chemotherapy, and involves the prominent formation of autophagic vacuoles in the cytoplasm. In this review, the synergistic effects of TCM and radiotherapy are summarized and the underlying mechanisms are illustrated, providing new therapeutic strategies for cancer. PMID:23760551

The Chinese herbal decoction formula Xiao Jian Zhong Tang (XJZT) is one of the classic formulas from the classic traditional Chinese medicine (TCM). Previous studies on XJZT found that it is effective for treating peptic ulcer, irritable bowel syndrome, functional gastroenteritis and similar psychosomatic disorders of the digestive organs. It has also been shown that all the herbs used in XJZT contain antioxidants. In this study, we investigated the in vitro DNA protection effect of the individual herb extracts and the whole formula. Water extract of the herbs and XJZT were used to pre-treat human lymphocytes. The lymphocytes were then exposed to hydrogen peroxide. The in vitro DNA protection effect of the herbs was investigated by comet assay. No DNA protective effect (P < 0.05) was found for individual herb extracts, but XJZT showed protection of human lymphocytic DNA upon oxidative stress (P < 0.05). The in vitro DNA protection effect of XJZT was conferred by the synergistic effect of the herbs, while the individual herbs had no such effect.

Single-target drugs have not achieved satisfactory therapeutic effects for complex diseases involving multiple factors. Instead, innovations in recent drug research and development have revealed the emergence of compound drugs, such as cocktail therapies and “polypills”, as the frontier in new drug development. A traditional Chinese medicine (TCM) prescription that is usually composed of several medicinal herbs can serve a typical representative of compound medicines. Although the traditional compatibility theory of TCM cannot be well expressed using modern scientific language nowadays, the fundamental purpose of TCM compatibility can be understood as promoting efficacy and reducing toxicity. This paper introduces the theory and methods of efficacy-oriented compatibility for developing component-based Chinese medicines. PMID:25864650

Complementary and alternative medicine (CAM) has gained increasing popularity over the last several decades internationally, leading to an increasing interest from decision makers and researchers as to how to assess the effectiveness of CAM. The attempts, however, have been unsatisfactory. The most important reason is a lack of attention to the theoretical characteristics of CAM, which are completely different from those of allopathic medicine or biomedicine. This study attempted to survey expert Traditional Chinese Medicine (TCM) practitioners in China to elucidate critical issues when assessing the effectiveness of TCM. A questionnaire (with 20 close-ended and 2 open-ended questions) about the influencing factors of measuring the cost and effectiveness of TCM was distributed to TCM practitioners who had been working in the field of research for at least 5 years and had published at least one related scientific article in the last 5 years. Internal consistency test was performed for all questions to verify the reliability of the questionnaire. Principal-component analysis was performed for remaining items after Kaiser-Meyer-Olkin (KMO) index and Bartlett's test of sphericity. A linear combination model was then built to evaluate the contribution of various factors involved for the selection of TCM into the health care reimbursement or insurance system. Of 429 questionnaires issued, 137 were returned from respondents from 31 medical and research institutions, giving a recovery rate of 31.93%. Internal consistency coefficient obtained was 0.745, indicating good reliability of this measurement scale, and the data passed the KMO test and Bartlett's test of sphericity (KMO index = 0.691). In addition, eight common factors were extracted after the rotation of principal-component analysis with a cumulative variance of 70.92%. Our findings suggested that factors to be considered during the selection of TCM in health care reimbursement or insurance system include patient preference, long-term outcomes, comparative study of alternative options between TCM and allopathic medicine or biomedicine, pharmacoeconomic evaluation results and the overall economic burden of patients, and side effects of TCM. In addition, the TCM experts stressed the need of cost-effectiveness assessment of the expensive TCM of similar therapeutic functions during the selection process. Moreover, during the evaluation of health-related quality of life of TCM, they warned to avoid overexaggeration of their roles and that the generic scale should be modified according to the clinical circumstances.

This study aims to investigate community pharmacist's perception on the provision of over-the-counter (OTC) traditional Chinese medicine (TCM) pharmaceutical services; focusing on the areas of their attitude, general practice, perceived barriers and suggested improvements. Questionnaire survey targeting community pharmacists in Harbin of China was applied in this study. Questionnaires were distributed and collected at community pharmacies. Data was analyzed by combining descriptive analysis and Chi-test. 280 valid questionnaires were collected, giving a response rate of 78%. Respondents generally showed positive attitude towards OTC TCM pharmaceutical services. However, they were uncertain about whether such pharmaceutical services should be considered as their primary responsibility. Respondents indicated that they acted proactively to find out all the medicines taken by their patients and to remind consumers of possible OTC TCM adverse reactions. However, they were less keen on recommending or re-directing consumers to suitable OTC TCM. The three main barriers hindering the provision of OTC TCM pharmaceutical service identified in this study were "insufficient professional knowledge" (54.6%), "ambiguity of the professional role of pharmacists" (54.6%) and "lack of scientific evidence of OTC TCM" (45.4%). The three main actions considered most relevant to improving pharmaceutical service of OTC TCM were "formulating or refining legislation to clarify the legal and professional role of pharmacists with respect to TCM" (60.7%), "strengthening training of pharmacists with respect to TCM" (57.9%), and "promoting public awareness of the pharmacist's role" (53.6%). According to the results of Chi-test, respondents' perceptions about the attitude, practice, perceived barriers, and improvement suggestions were significantly different depending on the education levels, certificate types and workloads of western medicine. The community pharmacists in Harbin, China were positive about the provision of OTC TCM pharmaceutical services. However, they were less certain about taking this duty as their primary responsibility. Insufficient knowledge and lack of role definition in the area of OTC TCM were found to be the major factors discouraging the provision of pharmaceutical service on OTC TCM by community pharmacists.

Research evidence suggests that educating nurses about traditional Chinese medicine (TCM) significantly improves their nursing care practice and the health care outcomes of community residents. The purpose of this study was to describe the current use of TCM by China's nursing workforce, as well as the typical nurse to physician ratio and types of TCM education that nurses receive in health care facilities. A large retrospective survey was conducted in Hubei Province, China, in 2010. The sample included 620 non-TCM hospitals, 120 TCM hospitals, and 1254 community health centers (CHCs). Descriptive analysis and 1-way analysis of variance were used to test statistical differences. There were 79 447 nurses employed, of which 1527 had a TCM degree and 5689 had on-the-job TCM education. Non-TCM hospitals employed more nurses than TCM hospitals and CHCs, and TCM hospitals employed more TCM nurses than non-TCM hospitals and CHCs. The median nurse to physician ratio varied by level of urbanization and type of health care facility, from 0.6 in rural CHCs to 1.3 in rural non-TCM hospitals. Differences in TCM education preparation of nurses were significantly different in the urban and rural settings and by type of health care facility. The study suggested a shortage of nurses educated in TCM in Hubei Province China, as well as uneven TCM workforce distribution. More opportunities for TCM education are needed for nurses, especially in CHCs where health promotion and chronic disease management are the most important and mandated functions.

Safety is an important component of the quality control of traditional Chinese medicine (TCM) preparation products, as well as an important guarantee for clinical application. Currently, the quality control of TCMs in Chinese Pharmacopoeia mostly focuses on indicative compounds for TCM efficacy. TCM preparations are associated with multiple links, from raw materials to products, and each procedure may have impacts on the safety of preparation. We make a summary and analysis on the factors impacting safety during the preparation of TCM products, and then expound the important role of the "multi-dimensional structure and process dynamic quality control technology system" in the quality safety of TCM preparations. Because the product quality of TCM preparation is closely related to the safety, the control over safety-related material basis is an important component of the product quality control of TCM preparations. The implementation of the quality control over the dynamic process of TCM preparations from raw materials to products, and the improvement of the TCM quality safety control at the microcosmic level help lay a firm foundation for the development of the modernization process of TCM preparations.

Atrial fibrillation (AF) is the most common cardiac arrhythmia, which is related to many cardiac and cerebral vascular diseases, especially stroke. It can therefore increase cardiovascular mortality and all-cause death. The current treatments of AF remain to be western drugs and radiofrequency ablation which are limited by the tolerance of patients, adverse side effects, and high recurrence rate, especially for the elderly. On the contrary, traditional Chinese medicine (TCM) with long history of use involves various treatment methods, including Chinese herbal medicines (CHMs) or bioactive ingredients, Chinese patent medicines, acupuncture, Qigong, and Tai Chi Chuan. With more and more researches reported, the active roles of TCM in AF management have been discovered. Then it is likely that TCM would be effective preventive means and valuable additional remedy for AF. The potential mechanisms further found by numerous experimental studies showed the distinct characteristics of TCM. Some CHMs or bioactive ingredients are atrial-selective, while others are multichannel and multifunctional. Therefore, in this review we summarized the treatment strategies reported in TCM, with the purpose of providing novel ideas and directions for AF management. PMID:28243308

The theory of lung being connected with large intestine, which is a major topic in Traditional Chinese Medicine (TCM), has guided clinical practice for thousands of years in China. In this study, we analyzed the history, main contents, clinical application, and material basis of the theory, to attempt to improve the potential clinical significance of "lung being connected with large intestine" in China. The lung being connected with large intestine was first described in "Huang Di Nei Jing", and formed one of the basic theories of TCM. For thousands of years, the majority of TCM practitioners explored this theory continuously, leading to its development and use as an important theory in the guidance of TCM clinics In the last decade, researchers in the field of integrated TCM and Western medicine have studied clinical applications and biomedical mechanisms with experimental methods to explore the implications of the theory. With the further development of science and technology, research concerning the theory of lung being connected with large intestine will be greatly stimulated and contribute to the modernization of TCM.

As traditional data management model cannot effectively manage the massive data in traditional Chinese medicine(TCM) due to the uncertainty of data object attributes as well as the diversity and abstraction of data representation, a management strategy for TCM data based on big data technology is proposed. Based on true characteristics of TCM data, this strategy could solve the problems of the uncertainty of data object attributes in TCM information and the non-uniformity of the data representation by using modeless properties of stored objects in big data technology. Hybrid indexing mode was also used to solve the conflicts brought by different storage modes in indexing process, with powerful capabilities in query processing of massive data through efficient parallel MapReduce process. The theoretical analysis provided the management framework and its key technology, while its performance was tested on Hadoop by using several common traditional Chinese medicines and prescriptions from practical TCM data source. Result showed that this strategy can effectively solve the storage problem of TCM information, with good performance in query efficiency, completeness and robustness.

2017-11-20

Traditional Chinese medicine (TCM) is an important part of China's medical system. Due to the prolonged low price of TCM procedures and the lack of an effective mechanism for dynamic price adjustment, the development of TCM has markedly lagged behind Western medicine. The World Health Organization (WHO) has emphasized the need to enhance the development of alternative and traditional medicine when creating national health care systems. The establishment of scientific and appropriate mechanisms to adjust the price of medical procedures in TCM is crucial to promoting the development of TCM. This study has examined incorporating value indicators and data on basic manpower expended, time spent, technical difficulty, and the degree of risk in the latest standards for the price of medical procedures in China, and this study also offers a price adjustment model with the relative price ratio as a key index. This study examined 144 TCM procedures and found that prices of TCM procedures were mainly based on the value of medical care provided; on average, medical care provided accounted for 89% of the price. Current price levels were generally low and the current price accounted for 56% of the standardized value of a procedure, on average. Current price levels accounted for a markedly lower standardized value of acupuncture, moxibustion, special treatment with TCM, and comprehensive TCM procedures. This study selected a total of 79 procedures and adjusted them by priority. The relationship between the price of TCM procedures and the suggested price was significantly optimized (p < 0.01). This study suggests that adjustment of the price of medical procedures based on a standardized value parity model is a scientific and suitable method of price adjustment that can serve as a reference for other provinces and municipalities in China and other countries and regions that mainly have fee-for-service (FFS) medical care.

To explore the role of traditional Chinese medicine (TCM) syndrome scores in effectiveness evaluation of clinical studies. Randomized controlled trials (RCTs) of TCM published in five journals in 2013 were retrieved, including Journal of Traditional Chinese Medicine (JTCM), Chinese Journal of Integrated Traditional and Western Medicine (CJITWM), Chinese Journal of Integrative Medicine (CJIM), Evidence-Based Complementary and Alternative Medicine (ECAM), and American Journal of Chinese Medicine (AJCM). The details of TCM syndrome scores and other relevant factors reported in articles were extracted and analyzed. Descriptive statistics and Chi-square test were used to describe general features of inclusive studies, ratios of reports on CM syndrome scores in each journal, formulated evidence, adopted evaluation rules, important degrees. The difference in the application rate of CM syndrome scores were compared in various diseases, diseases with or without CM syndrome typing, places where clinical studies were implemented, and different journals. A total of 240 RCTs were included, involving 178 published in Chinese version and 62 in English version. CM syndrome scores were used for effectiveness evaluation in 27.1% (65/240) of RCTs, of which, the highest application percentage was 35.3% (18/51) in RCTs published in CJITWM, and the lowest was 0 (0/7) in RCTs published in AJCM. There were 17 methods for grading TCM syndrome scores, of which Guideline for Clinical Research of New Chinese Herbal Medicine was most commonly used. Detailed grading standards for CM syndrome scores were reported in 46 RCTs, and CM syndrome scores were taken as primary or secondary outcomes in 6 RCTs. When describing the percentages of RCTs adopting TCM syndrome score by diseases classification, the lowest was 9.5% (2/21) in mental and behavioral disorders, and the highest was 39.1% (9/23) in endocrine, nutritional, and metabolic diseases. RCTs with TCM syndrome differentiation had a higher percentage of adopting TCM syndrome score than those without TCM syndrome differentiation (P < 0.01). Statistical differences were also found among RCTs published in Chinese core journals (32.0%), domestic science citation index (SCI) journals (28.6%), and overseas SCI journals (4.9%) (χ2 = 12.4593, P < 0.01). For RCTs conducted by Chinese scholars, the percentage of using TCM syndrome score was 32.0% in three journals from China, while 7.1% in two foreign language journals, showing significant difference (χ2 =7.3615, P < 0.01); none of RCTs conducted by foreign scholars used TCM syndrome scores for effectiveness assessment. There was a lack of agreeable and universal standards for TCM syndrome scores using in effectiveness evaluation. Therefore, it was not commonly used in domestic CM clinical studies. It was not so favorably agreed in overseas academic circles.

Cold Syndrome and Hot Syndrome are thousand-year-old key therapeutic concepts in traditional Chinese medicine (TCM), which depict the loss of body homeostasis. However, the scientific basis of TCM Syndrome remains unclear due to limitations of current reductionist approaches. Here, we established a network balance model to evaluate the imbalanced network underlying TCM Syndrome and find potential biomarkers. By implementing this approach and investigating a group of chronic superficial gastritis (CSG) and chronic atrophic gastritis (CAG) patients, we found that with leptin as a biomarker, Cold Syndrome patients experience low levels of energy metabolism, while the CCL2/MCP1 biomarker indicated that immune regulation is intensified in Hot Syndrome patients. Such a metabolism-immune imbalanced network is consistent during the course from CSG to CAG. This work provides a new way to understand TCM Syndrome scientifically, which in turn benefits the personalized medicine in terms of the ancient medicine and complex biological systems.

Patients with hypertension (HTN) reportedly have a higher risk of developing dementia. However, it remains unclear if use of Traditional Chinese Medicine (TCM), the most common form of complementary and alternative medicine, can help lower the risk of dementia for these patients. So the aim of the study was to investigate the effects of TCM on dementia risk among patients with hypertension. This longitudinal cohort study used the Taiwanese National Health Insurance Research Database (NHIRD) to identify 143,382 newly diagnosed hypertension patients aged 20-90 years who received treatment between 1998 and 2007. Among them, 52,365 (36.52%) had received TCM after the onset of hypertension (TCM users), and the remaining 91,017 patients (63.48%) were designated as a control group (non-TCM users). All enrollees were followed until the end of 2012 to record the incidence of dementia. A Cox proportional hazards regression model was used to compute the hazard ratio (HR) of dementia in patients who received TCM. During the 15-year follow-up, 3933 TCM users and 10,316 non-TCM users developed dementia, representing an incidence rate of 8.41 and 11.55%, respectively, per 1000 person-years. TCM users had a significantly reduced risk of dementia compared to non-TCM users (adjusted HR = 0.76; 95% confidence interval [CI] = 0.74-0.81). The predominant effect was observed among those treated with TCM longer than 180 days (adjusted HR = 0.65; 95% CI = 0.62-0.69). Among the commonly used TCM products, Tian-Ma-Gou-Teng-Yin, Dan-Shen (Radix Salviae Miltiorrhizae), Chuan-Niu-Xi (Radix Cyathulae), Ge-Gen (Radix Puerariae), Jia-Wei-Xiao-Yao-San, and Jue-Ming-Zi (Semen Cassiae) were significantly associated with a lower risk of dementia. Results from this population-based study support the effects of TCM on reducing dementia risk, which may provide a reference for dementia prevention strategies.

Quality of traditional Chinese medicine (TCM) plays a critical role in industry of TCM. Rapid development of TCM pharmaceutical areas is, however, greatly limited, since there are many issues not been resolved, concerning the quality study of TCM. Core concept of TCM quality as well as the characteristics of TCM was discussed, in order to guide the quality research and evaluation of TCM, further improve the level of TCM quality control. In this review, on the basis of systematic analysis of fundamental property and features of TCM in clinical application, the approaches and methods of quality marker (Q-marker) study were proposed through combination of transitivity and traceability of essentials of quality, correlation between chemical ingredients and drug property/efficacy, as well as analysis of endemicity of ingredients sharing similar pharmacophylogenetic and biosynthetic approaches. The approaches and methods of Q-marker study were proposed and the novel integrated pattern for quality assessment and control of TCM was established. The core concept of Q-marker has helped to break through the bottleneck of the current fragmented quality research of TCM and improved the scientificity, integrity and systematicness of quality control.

Traditional Chinese medicine (TCM) is one of the unique cultural treasures of Chinese; it represents a significant feature and prominent advantage of the healthcare cause in China. Data in this paper were fromWorld Health Organization, Chinese Bureau of Statistics, China National Knowledge Infrastructure, and PubMed. In recent years, TCM has established a solid foundation in Europe, which made great strides in legislation, education, research, and international exchange, and has enjoyed a vast development space in the continent. Now, TCM is embracing unprecedented development opportunities in Europe. At the same time, the stiff international competition poses a grave threat to China's TCM industry. With multiple cultural, legal, and institutional challenges, as well as talent shortages in the way, TCM is now facing many difficulties in Europe. To fully prepare and enact active and vigorous steps to seize opportunities, we should have a clear picture about the serious challenges hampering TCM development in Europe. The TCM development at overseas markets has shifted from a spontaneous trade activity into a national strategy spearheaded by the government and participated in by multiple stakeholders. We should make a systematic, comprehensive, and sustainable push in fields such as TCM therapy, healthcare, education, research, culture, and industry development. The ultimate goal is to bring TCMs to the global market and allow them to play a role in safeguarding public health along with modern medicines.

Introduction Traditional Chinese medicine (TCM) has accumulated some experience in curing stable angina pectoris (SAP) and efficacy has been demonstrated. Chinese patent medicines, known as modern dosage forms of TCM, can attain the desired effect in clinical application only with the guidance of TCM syndrome theory. However, due to their use by a large number of persons with little knowledge of TCM theories and practices, their efficacy and reputation have been seriously affected. Method and analysis Two common syndrome types of SAP in TCM, ‘qi deficiency and blood stasis’ and ‘qi stagnation and blood stasis’, will be studied in 144 subjects from four TCM hospitals in Tianjin in China using a partial crossover design. The two syndromes will be broken down into six symptom combinations; patients will select a combination of the most distressing to them, and then will be randomised into two groups. Each group, on the basis of routine medication, will be administered one kind of Chinese patent drug: Qishenyiqi Dripping Pills or Compound Danshen Dripping Pills. The treatment characteristics of the two medicines will be evaluated with the COME-PIO method developed by our research team. Ethics and dissemination This protocol has been approved by the medical ethics committee of Tianjin University of TCM (registration number TJUTCM-EC20130005). The study is safe and reliable. Trial registration number Chinese clinical trials register ChiCTR-TTRCC-14004406. PMID:25431225

Traditional Chinese Medicine (TCM), with a history of thousands of years of clinical practice, is gaining more and more attention and application worldwide. And TCM-based new drug development, especially for the treatment of complex diseases is promising. However, owing to the TCM’s diverse ingredients and their complex interaction with human body, it is still quite difficult to uncover its molecular mechanism, which greatly hinders the TCM modernization and internationalization. Here we developed the first online Bioinformatics Analysis Tool for Molecular mechANism of TCM (BATMAN-TCM). Its main functions include 1) TCM ingredients’ target prediction; 2) functional analyses of targets including biological pathway, Gene Ontology functional term and disease enrichment analyses; 3) the visualization of ingredient-target-pathway/disease association network and KEGG biological pathway with highlighted targets; 4) comparison analysis of multiple TCMs. Finally, we applied BATMAN-TCM to Qishen Yiqi dripping Pill (QSYQ) and combined with subsequent experimental validation to reveal the functions of renin-angiotensin system responsible for QSYQ’s cardioprotective effects for the first time. BATMAN-TCM will contribute to the understanding of the “multi-component, multi-target and multi-pathway” combinational therapeutic mechanism of TCM, and provide valuable clues for subsequent experimental validation, accelerating the elucidation of TCM’s molecular mechanism. BATMAN-TCM is available at http://bionet.ncpsb.org/batman-tcm.

Chinese cancer patients often use Traditional Chinese Medicine (TCM) herbal medicine during or after active cancer treatments. However, little is known about how TCM herbal medicine impacts cancer outcomes. This study aimed to evaluate the association between TCM herbal therapy and survival outcomes in patients with stage II or III colorectal cancer. We conducted an eight-center prospective cohort study in China among patients who had undergone radical resection for stage II and III colorectal cancer. All patients received comprehensive conventional treatments according to National Comprehensive Cancer Network (NCCN) guidelines, and follow-up visits were conducted over five years. We defined high exposure as a patient's use of TCM individualized herbs for more than one year, ascertained via clinical interviews. The primary outcome was disease-free survival (DFS), with overall survival (OS) as a secondary outcome. Between April 2007 and February 2009, we enrolled 312 patients into the cohort; 166 (53.2%) met the definition of high exposure to TCM herbs. Adjusting for covariates, high exposure to TCM was associated with both better DFS (hazard ratio [HR] = 0.62, 95% confidence interval [CI] = 0.39 to 0.98) and OS (HR = 0.31, 95% CI = 0.14 to 0.68). In subgroup exploratory analysis, the effects demonstrated that the differences in outcomes were statistically significant in patients who had received chemotherapy. Longer duration of TCM herbal use is associated with improved survival outcomes in stage II and III colorectal cancer patients in China. More research is needed to evaluate the effects and underlying mechanisms of herbal medicine on colorectal cancer outcomes. © The Author 2017. Published by Oxford University Press.

Medication errors such as potential inappropriate prescriptions would induce serious adverse drug events to patients. Information technology has the ability to prevent medication errors; however, the pharmacology of traditional Chinese medicine (TCM) is not as clear as in western medicine. The aim of this study was to apply the appropriateness of prescription (AOP) model to identify potential inappropriate TCM prescriptions. We used the association rule of mining techniques to analyze 14.5 million prescriptions from the Taiwan National Health Insurance Research Database. The disease and TCM (DTCM) and traditional Chinese medicine-traditional Chinese medicine (TCMM) associations are computed by their co-occurrence, and the associations' strength was measured as Q-values, which often referred to as interestingness or life values. By considering the number of Q-values, the AOP model was applied to identify the inappropriate prescriptions. Afterwards, three traditional Chinese physicians evaluated 1920 prescriptions and validated the detected outcomes from the AOP model. Out of 1920 prescriptions, 97.1% of positive predictive value and 19.5% of negative predictive value were shown by the system as compared with those by experts. The sensitivity analysis indicated that the negative predictive value could improve up to 27.5% when the model's threshold changed to 0.4. We successfully applied the AOP model to automatically identify potential inappropriate TCM prescriptions. This model could be a potential TCM clinical decision support system in order to improve drug safety and quality of care. Copyright © 2016 John Wiley & Sons, Ltd.

The Japan Geriatrics Society revised its criteria for the medical treatment and safety of the elderly in 2015. The Japan Geriatrics Society guidelines contain a chapter for traditional Chinese medicine (TCM; traditional medicines in East Asian countries, such as China, Japan, Korea, Taiwan, Vietnam and Singapore), because it is widely used for elderly patients and is sometimes covered by national medical insurance in Japan. The updated guidelines should be improved based on a comprehensive, systematic review and evidence grading.

To study the clinical efficacy of traditional Chinese medicine (TCM) intervention "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") for treating liver failure due to chronic hepatitis B. We designed the study as a randomized controlled clinical trial. Registration number of Chinese Clinical Trial Registry is ChiCTR-TRC-12002961. A total of 144 patients with liver failure due to infection with chronic hepatitis B virus were enrolled in this randomized controlled clinical study. Participants were randomly assigned to the following three groups: (1) a modern medicine control group (MMC group, 36 patients); (2) a "tonifying qi and detoxification" ("TQD") group (72 patients); and (3) a "tonifying the kidney to promote liver regeneration and repair by affecting stem cells and their microenvironment" ("TTK") group (36 patients). Patients in the MMC group received general internal medicine treatment; patients in the "TQD" group were given a TCM formula "tonifying qi and detoxification" and general internal medicine treatment; patients in the "TTK" group were given a TCM formula of "TTK" and general internal medicine treatment. All participants were treated for 8 wk and then followed at 48 wk following their final treatment. The primary efficacy end point was the patient fatality rate in each group. Measurements of various virological and biochemical indicators served as secondary endpoints. The one-way analysis of variance and the t-test were used to compare patient outcomes in the different treatment groups. At the 48-wk post-treatment time point, the patient fatality rates in the MMC, "TQD", and "TTK" groups were 51.61%, 35.38%, and 16.67%, respectively, and the differences between groups were statistically significant (P < 0.05). However, there were no significant differences in the levels of hepatitis B virus DNA or prothrombin activity among the three groups (P > 0.05). Patients in the "TTK" group had significantly higher levels of serum total bilirubin compared to MMC subjects (339.40 μmol/L ± 270.09 μmol/L vs 176.13 μmol/L ± 185.70 μmol/L, P = 0.014). Serum albumin levels were significantly increased in both the "TQD" group and "TTK" group as compared with the MMC group (31.30 g/L ± 4.77 g/L, 30.72 g/L ± 2.89 g/L vs 28.57 g/L ± 4.56 g/L, P < 0.05). There were no significant differences in levels of alanine transaminase among the three groups (P > 0.05). Safety data showed that there was one case of stomachache in the "TQD" group and one case of gastrointestinal side effect in the "TTK" group. Treatment with "TTK" improved the survival rates of patients with liver failure due to chronic hepatitis B. Additionally, liver tissue was regenerated and liver function was restored.

Understanding the functional mechanisms of the complex biological system as a whole is drawing more and more attention in global health care management. Traditional Chinese Medicine (TCM), essentially different from Western Medicine (WM), is gaining increasing attention due to its emphasis on individual wellness and natural herbal medicine, which satisfies the goal of integrative medicine. However, with the explosive growth of biomedical data on the Web, biomedical researchers are now confronted with the problem of large-scale data analysis and data query. Besides that, biomedical data also has a wide coverage which usually comes from multiple heterogeneous data sources and has different taxonomies, making it hard to integrate and query the big biomedical data. Embedded with domain knowledge from different disciplines all regarding human biological systems, the heterogeneous data repositories are implicitly connected by human expert knowledge. Traditional search engines cannot provide accurate and comprehensive search results for the semantically associated knowledge since they only support keywords-based searches. In this paper, we present BioTCM-SE, a semantic search engine for the information retrieval of modern biology and TCM, which provides biologists with a comprehensive and accurate associated knowledge query platform to greatly facilitate the implicit knowledge discovery between WM and TCM.

Background : Traditional Chinese Medicine (TCM) with its focus on herbal use is popular and appreciated worldwide with increased tendency, although its therapeutic efficacy is poorly established for most herbal TCM products. Treatment was perceived as fairly safe but discussions emerged more recently as to whether herb induced liver injury (HILI) from herbal TCM is a major issue; Methods : To analyze clinical and case characteristics of HILI caused by herbal TCM, we undertook a selective literature search in the PubMed database with the search items Traditional Chinese Medicine, TCM, alone and combined with the terms herbal hepatotoxicity or herb induced liver injury; Results : HILI caused by herbal TCM is rare and similarly to drugs can be caused by an unpredictable idiosyncratic or a predictable intrinsic reaction. Clinical features of liver injury from herbal TCM products are variable, and specific diagnostic biomarkers such as microsomal epoxide hydrolase, pyrrole-protein adducts, metabolomics, and microRNAs are available for only a few TCM herbs. The diagnosis is ascertained if alternative causes are validly excluded and causality levels of probable or highly probable are achieved applying the liver specific RUCAM (Roussel Uclaf Causality Assessment Method) as the most commonly used diagnostic tool worldwide. Case evaluation may be confounded by inappropriate or lacking causality assessment, poor herbal product quality, insufficiently documented cases, and failing to exclude alternative causes such as infections by hepatotropic viruses including hepatitis E virus infections; Conclusion : Suspected cases of liver injury from herbal TCM represent major challenges that deserve special clinical and regulatory attention to improve the quality of case evaluations and ascertain patients' safety and benefit.

Traditional Chinese medicine (TCM) prescription is the main therapies for disease prevention and treatment in Chinese medicine. Following the guidance of the theory of TCM and developing drug by composing prescriptions of TCM materials and pieces, it is a traditional application mode of TCM, and still widely used in clinic. TCM prescription has theoretical advantages and rich clinical application experience in dealing with multi-factor complex diseases, but scientific research is relatively weak. The lack of scientific cognition of the effective substances and mechanism of Chinese medicine leads to insufficient understanding of the efficacy regularity, which affects the stability of effect and hinders the improvement of quality of Chinese medicinal products. Component-based Chinese medicine (CCM) is an innovation based on inheritance, which breaks through the tradition of experience-based prescription and realize the transformation of compatibility from herbal pieces to components. CCM is an important achievement during the research process of modernization of Chinese medicine. Under the support of three national "973" projects, in order to reveal the scientific connotation of the prescription compatibility theory and develop innovative Chinese drugs, we have launched theoretical innovation and technological innovation around the "two relatively clear", and opened up the research field of CCM. CCM is an innovation based on inheritance, breaking through the tradition of experience based prescription, and realizing the transformation from compatibility of herbal pieces to component compatibility, which is an important achievement of the modernization of traditional Chinese medicine. In the past more than 10 years, with the deepening of research and the expansion of application, the theory and methods of CCM and efficacy-oriented compatibility have been continuously improved. The value of CCM is not only in developing new drug, more important is to build a communication bridge between traditional Chinese medicine and modern science and construct the system of key technologies which meet the need of innovation and development of TCM. This paper focused on the research progress, related concepts and technology development of CCM, as well as its application prospect in the theory research of Chinese medicine, development of innovative Chinese drugs, secondary development of Chinese patent medicine and upgrading of pharmaceutical technology.

To test the hypothesis that levels of sperm disomy fell significantly in six men treated by traditional Chinese medicine (TCM). Fluorescence in situ hybridization (FISH) was done on the sperm heads of six men before and during treatment by TCM. There was a significant reduction in sperm disomy in all six men. This coincided with TCM treatment. This is the first study reporting a significant reduction in sperm disomy in men over a given time course. The fact that this coincided with TCM treatment is intriguing but no conclusions can be drawn from this until placebo-controlled clinical trials are implemented.

Health food containing Chinese materia medica (CMM) conforms to the development demands of the age of big health and the theory of preventive treatment. In the view of health care and improvement of resisting diseases, it plays an important role in the market. It is very necessary to have further study and discussion on health food containing CMM. First of all, by comparing, analyzing and summarizing, the health food containing CMM could be defined as the health food which is qualified in security and functionality evaluation, with the traditional Chinese medicines(TCM) within TCM standards as the main raw materials, and the formulation-composition is based on the theory of TCM. It is characterized by higher safety than medicines, stronger biological activities than common food, multiple forms, abundant raw materials and integrated supervision and management. Secondly, we discussed the research and development (R&D) strategies and rules of health food containing CMM, pointing out that the core tasks of R&D include the investigation of formula, technology and the standards of quality. The fundamental principles of declaration and production include scientificity, rationality, reality and uniformity. Three key requirements (security, functionality and controllability) in the review as well as the process management of R&D and the key-points of risks control were summarized in this paper. Finally, the dynamic trends of policies and regulations related to health food containing CMM were analyzed in the view of registration, recording, raw materials and functions, and then related suggestions were proposed. Therefore, this article will be helpful in overall understanding the health food containing CMM and play a guiding role for its research and development.

Chemical fingerprinting is currently a widely used tool that enables rapid and accurate quality evaluation of Traditional Chinese Medicine (TCM). However, chemical fingerprints are not amenable to information storage, recognition, and retrieval, which limit their use in Chinese medicine traceability. In this study, samples of three kinds of Chinese medicines were randomly selected and chemical fingerprints were then constructed by using high performance liquid chromatography. Based on chemical data, the process of converting the TCM chemical fingerprint into two-dimensional code is presented; preprocess and filtering algorithm are also proposed aiming at standardizing the large amount of original raw data. In order to know which type of two-dimensional code (2D) is suitable for storing data of chemical fingerprints, current popular types of 2D codes are analyzed and compared. Results show that QR Code is suitable for recording the TCM chemical fingerprint. The fingerprint information of TCM can be converted into data format that can be stored as 2D code for traceability and quality control.

Cold Syndrome and Hot Syndrome are thousand-year-old key therapeutic concepts in traditional Chinese medicine (TCM), which depict the loss of body homeostasis. However, the scientific basis of TCM Syndrome remains unclear due to limitations of current reductionist approaches. Here, we established a network balance model to evaluate the imbalanced network underlying TCM Syndrome and find potential biomarkers. By implementing this approach and investigating a group of chronic superficial gastritis (CSG) and chronic atrophic gastritis (CAG) patients, we found that with leptin as a biomarker, Cold Syndrome patients experience low levels of energy metabolism, while the CCL2/MCP1 biomarker indicated that immune regulation is intensified in Hot Syndrome patients. Such a metabolism-immune imbalanced network is consistent during the course from CSG to CAG. This work provides a new way to understand TCM Syndrome scientifically, which in turn benefits the personalized medicine in terms of the ancient medicine and complex biological systems.

Chinese traditional philosophy believes that a healthy body can adjust itself to reach a dynamic equilibrium with the environment. At an ill state the equilibrium is lost. Any single medicine can only attack one problem and cannot recover the whole equilibrium. A prescription formulation (PF) usually contains an "emperor" or principal medicine, several "minister" or assistant medicines, some accessorial medicines, and one or two inducting or harmonizing edicines. Therefore different traditional Chinese medicine (TCM) appears in different number of PFs. The whole TCM system may be viewed as a network set composed of many complete graphs (PFs). The TCMs, which have the highest node degrees in the network, serve as the "bridges" between the complete graphs for forming the network. While the TCMs, which have lowest node degrees in the network, serve as the "emperors" in each complete graph. According to this idea we have performed a manual statistical investigation on approximately 1000 PFs and computed 8 different tatistical properties of the network. The results show that TCM system is a scale-free one and has a nice clustering structure. We are suggesting a dynamical model to describe the development of TCM system.

Cistanche species, known as Rou Cong-Rong in Chinese, are an endangered wild species and are mainly distributed in the arid lands and warm deserts of northwestern China. Within Traditional Chinese Medicine (TCM), Herba Cistanche is applied as a tonic and/or in a formula for chronic renal disease, impotence, female infertility, morbid leucorrhea, profuse metrorrhagia, and senile constipation. The chemical constituents of Herba Cistanche mainly consist of volatile oils, non-volatile phenylethanoid glycosides (PhGs), iridoids, lignans, alditols, oligosaccharides, and polysaccharides. There have been an increasing number of studies focusing on its bio-activities, including antioxidation, neuroprotection, and antiaging. The objective of this review is to introduce this herb to the world. Its taxonomy, distribution, and corresponding biological functions and molecular mechanisms are addressed in this review.

This article recorded the analysis and comparison between the medicinal nature theory of traditional Chinese medicine(TCM) and ethnomedicine(EM). The vocabulary of "medicinal nature" was suggested to indicate the properties of ethnomedicine. Based on the influence of TCM medicinal nature theory on EM in China, the application of medicinal nature theory in EM was divided into 3 classes, and the standardizing principles for EM medicinal nature were proposed. It was suggested that medicinal quality, flavor, tendency, tropism, degree and efficiency can be used for the classification standard for EM medicinal nature.

In modern China, most of the mass organizations of traditional Chinese medicine (TCM) were civilian and established by the individuals with self support financially.The TCM Improvement Research Association of Shanxi Province was the first official TCM organization in modern China. For the purpose of ruling and recognition of TCM, Yan Xishan, the chief executive of Shanxi province, gave a full support to its creation, development, and operation of the Association with the military and political officials in the government served as part-time staff members of a few of important position in the Association. The Association was given funding and policy support by official ways. The local administrative departments cooperated with the Association affairs actively. Because of the stable organization and the abundant fund, the TCM Improvement Research Association developed quickly and steadily. As a result, the Association had been playing an important and increasing role in academic research, TCM education, medical and epidemic prevention and so on. It had become one of the great national TCM academic societies with prolonged existence. As an official Association, it was characterized with a dual property: a better foundation for development and little independency.

Traditional Chinese medicine (TCM) is becoming increasingly popular and related adverse events are often ignored or underestimated. This systematic review aimed to evaluate the clinical characteristics and outcomes of TCM-induced liver injury (TCM-ILI) and to estimate the proportion of TCM-ILI in all drug-induced liver injuries (DILI). China National Knowledge Infrastructure, Wanfang, VIP, PubMed, and Embase databases were searched. Demographic, clinical, and survival data were extracted and pooled. Factors associated with worse outcomes were calculated. For the proportion meta-analyses, the data were pooled by using a random-effects model. Overall, 21,027 articles were retrieved, of which 625 were finally included. There was a predominance of female and older patients. The proportion of liver transplantation was 2.18% (7/321). The mortality was 4.67% (15/321). Male, higher aspartate aminotransferase and direct bilirubin, and lower albumin were significantly associated with an increased risk of death/liver transplantation in TCM-ILI patients. The proportion of TCM-ILI in all DILI was 25.71%. The proportion was gradually increased with year. Our work summarises current knowledge regarding clinical presentation, disease course, and prognosis of TCM-ILI. TCM can result in hepatotoxicity, even death or necessitate life-saving liver transplantation. Governmental regulation of TCM products should be strictly established.

Purpose : Depression is a sickening psychiatric condition that is prevalent worldwide. To manage depression, the underlying modes of antidepressant effect of herbals are important to be explored for the development of natural drugs. Tiansi Liquid is a traditional Chinese medicine (TCM) that is prescribed for the management of depression, however its underlying mechanism of action is still uncertain. The purpose of this study was to systematically investigate the pharmacological mode of action of a herbal formula used in TCM for the treatment of depression. Methods : Based on literature search, an ingredients-targets database was developed for Tiansi Liquid, followed by the identification of targets related to depression. The interaction between these targets was evaluated on the basis of protein-protein interaction network constructed by STITCH and gene ontology (GO) enrichment analysis using ClueGO plugin. Results : As a result of literature search, 57 components in Tiansi Liquid formula and 106 potential targets of these ingredients were retrieved. A careful screening of these targets led to the identification of 42 potential targets associated with depression. Ultimately, 327 GO terms were found by analysis of gene functional annotation clusters and abundance value of these targets. Most of these terms were found to be closely related to depression. A significant number of protein targets such as IL10, MAPK1, PTGS2, AKT1, APOE, PPARA, MAPK1, MIF, NOS3 and TNF-α were found to be involved in the functioning of Tiansi Liquid against depression. Conclusions : The findings elaborate that Tiansi Liquid can be utilized to manage depression, however, multiple molecular mechanisms of action could be proposed for this effect. The observed core mechanisms could be the sensory perception of pain, regulation of lipid transport and lipopolysaccharide-mediated signaling pathway.

Traditional Chinese medicine (TCM) plays an important role in the primary care system in many places, but research evidence on its effectiveness is largely lacking. The aim of the present study was to compare the effectiveness between TCM and Western medicine (WM) consultations in primary care. To evaluate whether medical consultations could improve the quality of life and health condition of patients in primary care and to find out whether there was any difference in the effectiveness bewteen TCM and WM. This was a prospective, longitudinal study on 290 patients of one TCM public and 841 patients of two WM general outpatient clinics (GOPC) in Hong Kong when they consulted for an episodic illness. All patients attending a TCM GOPC in TWH, and the two WM GOPC (TWH and ALC), who fullfilled the inclusion criteria were invited to participate. Each patient answered a structured questionnaire on the presenting complaint, socio-demography, chronic morbidity and service utilization, the Chinese Quality of Life instrument (ChQOL) and the SF-36V2 Health Survey immediately before and two weeks after the doctor consultation. The Global Rating on change Scale (GRS) was also administered in the week 2 assessment. The primary outcomes were changes in the ChQOL and SF-36V2 HRQOL scores. Secondary outcomes included the GRS score. The significance of the change within individual were tested by paired t-tests. The differences in change in scores between WM and TCM were tested by independent sample-t-tests or chi-square, as appropriate. Multivariate regresions were used to determine the independent effect of type of medicine on the change in HRQOL scores. Mean ChQOL and SF-36V2 scores of subjects improved significantly two weeks after TCM or WM consultations in all domains except for the Physical form domain of ChQOL. The greatest improvements were found in the SF-36V2 physical-health related domains. 78% TCM clinics and 71% of subjects WM clinics reported an improvement in GRS. The proportion of subjects who had improvement in HRQOL scores were lower among subjects consulting the WM clinic (72.3%) than those consulting TCM clinics (100%) but the difference was not significant after correction for baseline scores. Both TCM and WM consultations were associated with significant improvement in HRQOL in over 90% of patients. There was no singificant difference between the effectiveness of TCM and WM consultations. The results support the role of TCM as an alternative primary care service in Hong Kong. Copyright © 2011 Elsevier Ltd. All rights reserved.

The MD Anderson Symptom Inventory (MDASI) is a brief, yet thorough, patient-reported outcomes measure for assessing the severity of common cancer-related symptoms and their interference with daily functioning. We report the development of an MDASI version tailored for use with Traditional Chinese Medicine in China (the MDASI-TCM). Chinese-speaking patients with mixed cancer types (n = 317) participated in the study. The development and validation process included four steps: 1) identify candidate TCM-specific items, with input from patients, oncologists, and TCM specialists; 2) eliminate candidate TCM items lacking relevance, based on patient report; 3) psychometrically examine the MDASI-TCM's validity and reliability in cancer patients receiving TCM-based care; and 4) cognitively debrief patients to assess the MDASI-TCM's relevance, understandability, and acceptability. Seven TCM-specific symptom items (sweating, feeling cold, constipation, bitter taste, coughing, palpitations, and heat in palms/soles) were clinically and psychometrically meaningful to add to the core MDASI. Approximately 61% of patients had moderate to severe symptoms (rated ≥5 on the MDASI-TCM's 0-10 scale). Cronbach α coefficients were .90 for symptom-severity items and .93 for interference items, indicating internal consistency reliability. Known-group validity was substantiated by the MDASI-TCM's detection of differences in symptom severity according to performance status (P < .001) and interference levels by cancer stage (P < .05). Cognitive debriefing indicated that patients found the MDASI-TCM to be an understandable, easy-to-use tool. The Chinese MDASI-TCM is a valid, reliable, and concise measure of symptom severity and interference that can be used to assess Chinese cancer patients and survivors receiving TCM-based care. © The Author 2017.

Traditional Chinese medicine (TCM) property theory is believed to be a key and difficult point of basic theory studies of TCM. Complex concepts, components and characteristics of TCM property have long puzzled researchers and urged them to develop new angles and approaches. In the view of cognitive science, TCM property theory is a cognitive process of storing, extracting, rebuilding and summarizing the sensory information about TCMs and their effects during the medical practice struggling against diseases under the guidance of traditional Chinese philosophical thinking. The cognitive process of TCM property has particular cognitive elements and strategies. Taking into account clinical application characteristics of TCMs, this study defines the particular cognitive elements. In the combination of research methods of modern chemistry, biology and mathematics, and on the basis early-stage work for five years, we have built a TCM property cognition model based on three elements and practiced with drugs with pungent and hot properties as example, in the hope of interpreting TCM properties with modern science and providing thoughts for the nature of medical properties and instruction for rational clinical prescription.

Given the challenges in exploring lifelong therapy with little side effect for human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) cases, there is increasing interest in developing traditional Chinese medicine (TCM) treatments based on specific TCM syndrome. However, there are few objective and biological evidences for classification and diagnosis of HIV/AIDS TCM syndromes to date. In this study, iTRAQ-2DLC-MS/MS coupled with bioinformatics were firstly employed for comparative proteomic profiling of top popular TCM syndromes of HIV/AIDS: accumulation of heat-toxicity (AHT) and Yang deficiency of spleen and kidney (YDSK). It was found that for the two TCM syndromes, the identified differential expressed proteins (DEPs) as well as their biological function distributions and participation in signaling pathways were significantly different, providing biological evidence for the classification of HIV/AIDS TCM syndromes. Furthermore, the TCM syndrome-specific DEPs were confirmed as biomarkers based on western blot analyses, including FN1, GPX3, KRT10 for AHT and RBP4, ApoE, KNG1 for YDSK. These biomarkers also biologically linked with the specific TCM syndrome closely. Thus the clinical and biological basis for differentiation and diagnosis of HIV/AIDs TCM syndromes were provided for the first time, providing more opportunities for stable exertion and better application of TCM efficacy and superiority in HIV/AIDS treatment.

To qualitatively categorize Traditional Chinese Medicine (TCM) differential diagnoses in a sample of veterans with Gulf War Illness (GWI) pre- and postacupuncture treatment. The authors randomized 104 veterans diagnosed with GWI to a 6-month acupuncture intervention that consisted of either weekly or biweekly individualized acupuncture treatments. TCM differential diagnoses were recorded at baseline and at 6 months. These TCM diagnoses were evaluated using Matrix Analysis to determine co-occurring patterns of excess, deficiency, and channel imbalances. These diagnoses were examined within and between participants to determine patterns of change and to assess stability of TCM diagnoses over time. Frequencies of diagnoses of excess, deficiency, and channel patterns were tabulated. Diagnoses of excess combined with deficiency decreased from 43% at baseline to 39% of the sample at 6 months. Excess+deficiency+channel imbalances decreased from 26% to 17%, while deficiency+channel imbalances decreased from 11% to 4% over the study duration. The authors observed a trend over time of decreased numbers of individuals presenting with all three types of differential diagnosis combinations. This may suggest that fewer people were diagnosed with concurrent excess, deficiency, and channel imbalances and perhaps a lessening in the complexity of their presentation. This is the first published article that organizes and defines TCM differential diagnoses using Matrix Analysis; currently, there are no TCM frameworks for GWI. These findings are preliminary given the sample size and the amount of missing data at 6 months. Characterization of the TCM clinical presentation of veterans suffering from GWI may help us better understand the potential role that East Asian medicine may play in managing veterans with GWI and the design of effective acupuncture treatments based on TCM. The development of a TCM manual for treating GWI is merited.

Infertility affects about 15% of couples. Many women proceed to reproductive clinics for in vitro fertilisation, with some exploring a range of alternative or complementary options. We explored women's experiences with traditional Chinese medicine (TCM) for the treatment of infertility. We interviewed 25 women with primary or secondary infertility, recurrent miscarriage or stillbirth who had consulted TCM practitioners. We explored women's experience of TCM and fertility clinics and analysed interviews thematically. Women appreciated the noninvasive diagnostic techniques TCM practitioners used to identify 'imbalances' causing infertility, learnt how to assess fertility indicators, and valued the focused personal care provided. All noticed improved menstrual cycles. Women wished for integration of holistic therapies in infertility management. Our study highlights the need for patient centred care and fertility education, and suggests that some women see a possible role for TCM as part of infertility management.

This study investigated gender differences in the use of traditional and complementary medicine (TCM) in Ghana. Using an interviewer-administered questionnaire, we collected data from March to June 2013 from 324 randomly sampled adults in the Ashanti region. The prevalence of TCM use in the prior 12 months was 86 percent. Females constituted the majority (61 percent) of TCM users. Female TCM users were more likely than male users to have had only a basic education, been traders (p ˂ .0001), and have health insurance (p ˂ .05). Using multiple logistic regression, TCM use was associated with urban residence for females (odds ratio [OR] = 7.82; 95 percent confidence interval [CI]: 1.28-47.83) but negatively related for males (OR = 0.032; 95 percent CI: 0.002-0.63). Being self-employed was associated with TCM use among males (OR = 7.62; 95 percent CI: 1.22-47.60), while females' TCM use was associated with higher income (OR = 3.72; 95 percent CI: 1.21-11.48) and perceived efficacy of TCM (OR = 5.60; 95 percent CI: 1.78-17.64). The African sociocultural structure vests household decision-making power in men but apparently not regarding TCM use, and the factors associated with TCM use largely differed by gender. These findings provide ingredients for effective health policy planning and evaluation. Adoption and modernization of TCM should apply a gendered lens.

Background Recent advances in Web and information technologies with the increasing decentralization of organizational structures have resulted in massive amounts of information resources and domain-specific services in Traditional Chinese Medicine. The massive volume and diversity of information and services available have made it difficult to achieve seamless and interoperable e-Science for knowledge-intensive disciplines like TCM. Therefore, information integration and service coordination are two major challenges in e-Science for TCM. We still lack sophisticated approaches to integrate scientific data and services for TCM e-Science. Results We present a comprehensive approach to build dynamic and extendable e-Science applications for knowledge-intensive disciplines like TCM based on semantic and knowledge-based techniques. The semantic e-Science infrastructure for TCM supports large-scale database integration and service coordination in a virtual organization. We use domain ontologies to integrate TCM database resources and services in a semantic cyberspace and deliver a semantically superior experience including browsing, searching, querying and knowledge discovering to users. We have developed a collection of semantic-based toolkits to facilitate TCM scientists and researchers in information sharing and collaborative research. Conclusion Semantic and knowledge-based techniques are suitable to knowledge-intensive disciplines like TCM. It's possible to build on-demand e-Science system for TCM based on existing semantic and knowledge-based techniques. The presented approach in the paper integrates heterogeneous distributed TCM databases and services, and provides scientists with semantically superior experience to support collaborative research in TCM discipline.

To compare the difference in the efficacy on post-herpetic neuralgia among TCM herbal cupping therapy, Chinese medicine thermal compressing therapy and mecobalamine. Fifty-seven cases were randomized into a TCM herbal cupping group, a thermal compressing group and a western medicine group, 19 cases in each one. The oral administration of ibuprofen was applied in every group. In the herbal cupping group, the bamboo cups soaked in the boiled Chinese herbal decoction were sucked on the most significant painful area. In the thermal compressing group, the towel soaked in the boiled Chinese herbal decoction was compressed on the most significant painful area. In the medication group, the muscular injection of mecobalamine was adopted. The treatment was given once a day, for 2 weeks totally in each group. SF-MPQ score and clinical efficacy before and after treatment were observed in each group. The remarkable effective rates were 78.9% (15/19), 36.8% (7/19) and 5.3% (1/19) in the TCM herbal cupping group, thermal compressing group and western medicine group separately. The efficacy in the TCM herbal cupping group was significantly superior to the thermal compressing group and western medicine group (all P < 0.05), and that in the thermal compressing group was superior to the western medicine group (P < 0.05). After treatment, SF-MPQ score was reduced significantly in each group (P < 0.001, P < 0.01). The score in the herbal cupping group was reduced more significantly as compared with the thermal compressing group and western medicine group (all P < 0.01). The improvement in pain in the thermal compressing group was superior to the western medicine group (P < 0.01). TCM herbal cupping therapy achieves the superior efficacy for post-herpetic neuralgia and relieves pain effectively of the patients, which is more advantageous than CM herbal thermal compressing therapy and Mecobalamine.

The true meanings of the terms of traditional Chinese medicine (TCM) need to be analyzed on a logical basis. It is not suitable to use a new term to interpret an old term of TCM, or arbitrarily specify the special term of TCM corresponding to some substances of modern medicine. In philosophy of language, language has a logical structure, which reflects the structure of the world, that is to say, language is the picture of the world in a logical sense. Using this idea, the authors collected the ancient literature on "kidney essence", and extracted each necessary condition for "kidney essence". All necessary conditions formed a sufficient condition to define the term "kidney essence". It is expected that this example can show the effectiveness of philosophy of language in analysis of the terms of TCM.

The mechanism of the therapeutic action of antidepressants remains uncertain in traditional Chinese medicine (TCM). In this study, we selected 7 classical TCM prescriptions and utilised an automatic video-tracking system to monitor the rest/wake behaviour of larval zebrafish at 4 days post-fertilisation (dpf) for 48 hours. We found that the curative effects of the prescriptions were dose-dependent. K-means clustering was performed according to the shared behavioural phenotypes of the zebrafish. The results revealed that the rest/wake behavioural profiles induced by the same class of prescriptions were similar. A correlation analysis was conducted between the TCM prescriptions and the known compounds. The results showed that the TCM prescriptions correlated well with some well-known compounds. Therefore, we predicted that they may share a similar mechanism of action. This paper describes the first study to combine TCM research with zebrafish rest/wake behaviour in vivo and presents a powerful approach for the discovery of the mechanism of action of TCM prescriptions.

Traditional Chinese Medicine utilization has rapidly increased worldwide. However, there is limited database provides the information of TCM herbs and diseases. The study aims to identify and evaluate the meaningful associations between TCM herbs and breast cancer by using the association rule mining (ARM) techniques. We employed the ARM techniques for 19.9 million TCM prescriptions by using Taiwan National Health Insurance claim database from 1999 to 2013. 364 TCM herbs-breast cancer associations were derived from those prescriptions and were then filtered by their support of 20. Resulting of 296 associations were evaluated by comparing to a gold-standard that was curated information from Chinese-Wikipedia with the following terms, cancer, tumor, malignant. All 14 TCM herbs-breast cancer associations with their confidence of 1% were valid when compared to gold-standard. For other confidences, the statistical results showed consistently with high precisions. We thus succeed to identify the TCM herbs-breast cancer associations with useful techniques.

Hollow fiber cell fishing (HFCF) based on hepatoma HepG-2 cells, human renal tubular ACHN cells or human cervical carcinoma HeLa cells, coupled with high-performance liquid chromatography (HPLC), was developed and employed to research the major active components in Zi-Cao-Cheng-Qi decoction both in vitro and in vivo. The research showed that the active components, such as hesperidin, magnolol, honokiol, shikonin, emodin and β,β'-dimethylacrylshikonin were screened out by HFCF based on the cancer cells in vitro, furthermore they can be absorbed into blood and reach in the target organ, and some of the active components can be fished by the cells and maintain effective concentrations. Before application of HFCF with HPLC, cell growth state, cell survival rate, positive effect on screening results binding between active centers on the fiber and target components, repeatability of retention times and relative peak areas of the target analytes were analysed and investigated. In short, HFCF with HPLC is a simple, inexpensive, effective, and reliable method that can be used in researching active components from traditional Chinese medicine (TCM) and its formula both in vitro and in vivo, elucidating preliminarily the TCM characteristics of multiple components and multiple targets, laying a foundation for expounding the antitumor efficacy material basis in TCM.

Traditional Chinese medicine (TCM) is an alternative treatment for cancer with its effect by stimulating host immune response for cytotoxic activity against liver cancer. No studies evaluated TCM treatment on survival of liver cancer patients. This study determined whether the combination of TCM and conventional cancer treatment affects the survival of liver cancer patients. A retrospective cohort study was conducted in 127 237 newly diagnosed liver cancer patients from 2000 to 2009 in the National Health Insurance Program database. Among these patients, 30 992 (24.36%) used TCM for liver cancer care. All patients were followed up until 2011. The mean follow-up was 5.67 years (SD 1.47) for TCM users and 5.49 years (SD 3.64) for non-TCM users. Compared with patients without TCM use, patients with TCM use were significantly associated with a decreased risk of death [hazard ratio (HR) = 0.65, 95% confidence interval (CI) = 0.64-0.66] with multivariate adjustment. A similar significant protective effect of TCM use across various subgroups of chronic liver diseases was also observed. Jia Wei Xiao Yao San (HR = 0.89, 95% CI = 0.81-0.96) and Chai Hu Shu Gan Tang (HR = 0.86, 95% CI = 0.78-0.95) were the most effective TCM agents that improved survival. This cohort study provided information that adjunctive therapy with TCM may improve the survival in liver cancer patients. Further studies are needed to confirm the potential role of TCM in HCC. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Cancer 'patients' are increasingly using traditional indigenous and complementary medicines (T&CM) alongside conventional medical treatments to both cure and cope with their cancer diagnoses. To date T&CM use among Indigenous cancer patients from Australia, Canada, New Zealand, and the United States has not been systematically reviewed. We systematically searched bibliographic databases to identify original research published between January 2000 and October 2017 regarding T&CM use by Indigenous cancer patients in Australia, Canada, New Zealand, and the United States. Data from records meeting eligibility criteria were extracted and appraised for quality by 2 independent reviewers. Twenty-one journal articles from 18 studies across all 4 countries met our inclusion criteria. T&CM use ranged from 19% to 57.7% (differing across countries). T&CM was mostly used concurrently with conventional cancer treatments to meet their spiritual, emotional, social, and cultural needs; however, bush, traditional, and herbal medicines were used in a minority of cases as an alternative. Our findings highlight the importance of T&CM use to Indigenous cancer patients across these 4 countries; we identified multiple perceived spiritual, emotional and cultural benefits to its use. The patient's perception of their health professional's attitudes toward T&CM in some cases hindered or encouraged the patient's disclosure. Additional research is required to further explore the use and disclosure of T&CM among Indigenous cancer patients to help inform and ensure effective, safe, coordinated care for Indigenous cancer patients that relies on shared open decision making and communication across patients, communities, and providers.

To investigate whether a training process that focused on a questionnaire-based diagnosis in Traditional Chinese Medicine (TCM), and developing diagnostic consensus, would improve the agreement of TCM diagnoses among 10 TCM practitioners evaluating patients with temporomandibular joint disorder (TMJD). Evaluation of a diagnostic training program at the Department of Family and Community Medicine, University of Arizona, Tucson, Arizona, and the Oregon College of Oriental Medicine, Portland, Oregon. Screened participants for a study of TCM for TMJD. PRACTITIONERS: Ten (10) licensed acupuncturists with a minimum of 5 years licensure and education in Chinese herbs. A training session using a questionnaire-based diagnostic form was conducted, followed by waves of diagnostic sessions. Between sessions, practitioners discussed the results of the previous round of participants with a focus on reducing variability in primary diagnosis and severity rating of each diagnosis: 3 waves of 5 patients were assessed by 4 practitioner pairs for a total of 120 diagnoses. At 18 months, practitioners completed a recalibration exercise with a similar format with a total of 32 diagnoses. These diagnoses were then examined with respect to the rate of agreement among the 10 practitioners using inter-rater correlations and kappas. The inter-rater correlation with respect to the TCM diagnoses among the 10 practitioners increased from 0.112 to 0.618 with training. Statistically significant improvements were found between the baseline and 18 month exercises (p < 0.01). Inter-rater reliability of TCM diagnosis may be improved through a training process and a questionnaire-based diagnosis process. The improvements varied by diagnosis, with the greatest congruence among primary and more severe diagnoses. Future TCM studies should consider including calibration training to improve the validity of results.

Astragalus-containing Traditional Chinese Medicine, with and without prescription based on syndrome differentiation, combined with chemotherapy for advanced non-small-cell lung cancer: a systemic review and meta-analysis.

Traditional Chinese Medicine (tcm) is used in China as part of the treatment for non-small-cell lung cancer (nsclc) and often includes prescription of herbal therapy based on syndrome differentiation. Studies of various Astragalus-based Chinese medicines combined with platinum-based chemotherapy in the treatment of lung cancer are popular in East Asia, particularly in China. The aim of the present study was to perform a systematic review and meta-analysis comparing platinum-based chemotherapy alone with platinum-based chemotherapy plus Astragalus-based Chinese botanicals, with and without prescription based on syndrome differentiation, as first-line treatment for advanced nsclc. We searched the Chinese Biomedical Literature database, the China National Knowledge Internet, the VIP Chinese Science and Technology Periodicals Database, PubMed, embase, the Cochrane databases, and abstracts presented at meetings of the American Society of Clinical Oncology, the World Conference on Lung Cancer, the European Society for Medical Oncology, and the Chinese Society of Clinical Oncology for all eligible studies. Endpoints were overall survival; 1-year, 2-year, and 3-year survival rates; performance status; overall response rate; and grade 3 or 4 adverse events. Subgroup analyses based on herbal formulae individualized using syndrome differentiation or on oral or injection patent medicines were performed using the Stata software application (version 11.0: StataCorp LP, College Station, TX, U.S.A.) and a fixed-effects or random-effects model in case of heterogeneity. Results are expressed as a hazard ratio (hr) or relative risk (rr), with corresponding 95% confidence intervals (cis). Seventeen randomized studies with scores on the Jadad quality scale of 2 or more, representing 1552 patients, met the inclusion criteria. Compared with platinum-based chemotherapy alone, the addition of Astragalus-based tcm to chemotherapy was associated with significantly increased overall survival (hr: 0.61; 95% ci: 0.42 to 0.89; p = 0.011); 1-year (rr: 0.73; 95% ci: 0.65 to 0.82; p < 0.001), 2-year (rr: 0.3344; 95% ci: 0.237 to 0.4773; p < 0.001), and 3-year survival rates (rr: 0.30; 95% ci: 0.17 to 0.53; p < 0.001); performance status (rr: 0.43; 95% ci: 0.34 to 0.55; p < 0.001); and tumour overall response rate (rr: 0.7982; 95% ci: 0.715 to 0.89; p < 0.001). Subgroup analyses indicated that Astragalus herbal formulae given based on syndrome differentiation were more effective than Astragalus-based oral and injection patent medicines. Side effects-including anemia, neutropenia, thrombocytopenia, fatigue, poor appetite, nausea, and vomiting-were significantly more frequent with platinum-based chemotherapy alone than when platinum-based chemotherapy was combined with Astragalus-based tcm. Astragalus-based Chinese botanical therapy, especially when based on syndrome differentiation, is associated with increased efficacy of platinum-based chemotherapy and decreased platinum-derived toxicities for patients with advanced nsclc.

Aims The aim was to perform a systematic review of the efficacy of traditional Chinese medicines (TCM) in cardiovascular disease. Methods Electronic databases were searched up to 11 November 2015 for all randomized‐controlled trials evaluating the effect of TCM in hypertension, ischaemic stroke, heart failure, coronary heart disease and type 2 diabetes mellitus. Pooled odds ratios (ORs) were calculated using a fixed‐effects model. Results Four hypertension studies were eligible for statistical analysis and included 133 patients receiving TCM and 130 control patients. There were significant reductions in systolic blood pressure in patients receiving TCM, comparable to results achieved with pharmaceutical medicines. An OR of 3.781 (95% confidence interval 2.392, 5.977; P = 0.000) was observed for the anti‐hypertensive effect of TCM. Significant heterogeneity was present (P = 0.011), with a tendency towards publication bias that did not reach significance (P = 0.05275). Outcome measures for other cardiovascular diseases were inconsistent. Conclusions Certain TCM compounds appear to have significant anti‐hypertensive effects, and although some are associated in some studies with improved outcomes in coronary heart disease, heart failure and type 2 diabetes mellitus, the data are inconsistent and will require large‐scale randomized‐controlled trials to allow full evaluation of any potential therapeutic benefit in these areas.

Title. Chemotherapy-induced myelosuppression lowers the quality of life in breast cancer patients and causes many complications. Traditional Chinese Medicine (TCM) is a widely used complementary and alternative medicine therapies. Objective. To study whether TCM can reduce the incidence of chemotherapy-induced leukopenia, neutropenia, and febrile neutropenia (FN) in breast cancer patients. Methods. The data were analyzed retrospectively between patients who received TCM treatment (group 1, n = 453) and patients who did not receive TCM treatment (group 2, n = 359). Significant risk factors associated with the occurrence of chemotherapy-induced leukopenia, neutropenia, and FN were identified using multivariate analysis. Propensity score-matched patients were analyzed to adjust for any baseline differences. Results. Group 1 patients had a significantly lower rate of chemotherapy-induced severe leukopenia, neutropenia, and FN, compared with group 2 (43% versus 71%, P < 0.0001, 72% versus 78%, P = 0.005, 6% versus 24%, P < 0.0001, resp.). Multivariate analysis revealed that chemotherapy regimens containing anthracyclines combined with paclitaxel or docetaxel were the most significant predictor. Subgroup analysis indicated that TCM treatment showed benefit in relieving chemotherapy-induced leukopenia and FN in most chemotherapy regimens. Conclusions. TCM treatment could lower the risk of severe chemotherapy-induced leukopenia, neutropenia, and FN in breast cancer patients. PMID:26347793

Diabetic nephropathy (DN) is the most serious chronic complications of diabetes; 20–40% of diabetic patients develop into end stage renal disease (ESRD). However, exact pathogenesis of DN is not fully clear and we have great difficulties in curing DN; poor treatment of DN led to high chances of mortality worldwide. A lot of western medicines such as ACEI and ARB have been demonstrated to protect renal function of DN but are not enough to delay or retard the progression of DN; therefore, exploring exact and feasible drug is current research hotspot in medicine. Traditional Chinese medicine (TCM) has been widely used to treat and control diabetes and its complications such as DN in a lot of scientific researches, which will give insights into the mechanism of DN, but they are not enough to reveal all the details. In this paper, we summarize the applications of herbal TCM preparations, single herbal TCM, and/or monomers from herbal TCM in the treatment of DN in the recent 10 years, depicting the renal protective effects and the corresponding mechanism, through which we shed light on the renal protective roles of TCM in DN with a particular focus on the molecular basis of the effect and provide a beneficial supplement to the drug therapy for DN.

Traditional Chinese medicine (TCM) and acupuncture has been gradually accepted by the mainstream society since the 1970s and has been rapidly expanding, accompanying the tide of Chinese immigration since the 1980s. Acupuncture legislation has been approved by the governments of 5 provinces in Canada between 1988 and 2014. After the acceptance of self-regulation, 5 corresponding colleges were established, one after another. The code of ethics and professional practice standard were developed by the Colleges. British Columbia (BC) became the first Canadian province to offer acupuncture treatments as a supplementary benefit for its Medical Services Plan premium assistance recipients beginning in 2008. The 5 colleges united to form the Canadian Alliance of Regulatory Bodies of Traditional Chinese Medicine Practitioners and Acupuncturists (CARBTCMPA) in the same year. The Entry-level Occupational Competencies for the Practice of TCM in Canada were developed by CARB-TCMPA in 2010. The Pan-Canadian registration examinations for acupuncturists, herbalists and TCM practitioners have been administered and scheduled since 2013. The Entry-level Occupational Competencies for Doctors of TCM were developed by College of Traditional Chinese Medicine Practitioners and Acupuncturists of British Columbia (CTCMA-BC) in 2014. It sketches the blueprint for future development of the TCM profession in Canada.

With the transformation of modern medicinal pattern, medical studies are confronted with methodological challenges. By analyzing two methodologies existing in the study of physical matter system and information system, the article points out that traditional Chinese medicine (TCM), especially the treatment based on syndrome differentiation, embodies information conception of methodological positions, while western medicine represents matter conception of methodological positions. It proposes a new way of thinking about combination of TCM and western medicine by combinating two kinds of methodological methods.

This study is designed to compare the efficacy and safety of traditional Chinese medicine (TCM) with western medicine (WM) in the management of rheumatoid arthritis (RA). This is a 24-week, randomized, multicenter, single-blind study comparing TCM with WM (as used in China) carried out between June 2002 and December 2004 in nine research centers in China, involving 489 patients. Patients were randomized to receive TCM (n = 247), MTX and SSZ (n = 242). MTX was started at a dose of 5 mg to a final dose of 7.5-15 mg weekly. The maintenance dose was 2.5-7.5 mg weekly. The starting dose of SSZ was 0.25 g bid, increasing by 0.25 g a day once a week to a final dose of 0.5-1 g qid. The maintenance dose was 0.5 g tid to qid. Primary end point was the proportion of patients with response according to the American College of Rheumatology 20 % improvement criteria (ACR20) at weeks 24. At 24 weeks, ACR20 responses were 53.0 % in TCM group and 66.5 % in WM group, (P < 0.001) at 24 weeks. ACR 50 responses were 31.6 % of TCM group and 42.6 % in WM group, (P = 0.01). ACR70 responses were 12.6 % in TCM group and 17.4 % in WM group, (P = 0.14). Side effects were observed more frequently in WM group. In this study, ACR20, ACR50 responses at 24 weeks were significantly better in the WM treated group, by intention to treat (ITT) and per protocol analysis. The ACR 70 response showed no significant difference between the two groups. TCM, while effective in treating RA, appears to be less effective than WM in controlling symptoms, but TCM is associated with fewer side effects.

Realgar which contains arsenic components has been used in traditional Chinese medicine (TCM) as an anticancer drug. However, neither Realgar nor its formula are soluble in water. As a result, high dose of Realgar has to be administered to achieve an effective blood medicine concentration, and this is associated with adverse side effects. The objective of the present study was to increase the solubility of a formula using hydrometallurgy technology as well as investigating its effects on in vitro and in vivo cell proliferation and apoptosis in Sarcoma-180 cell line. Antiproliferative activity of Realgar Bioleaching Solution (RBS) was evaluated by MTT assay. Further, effects of RBS on cell proliferation and apoptosis were studied using flow cytometry and transmission electron microscopy. Kunming mice were administered RBS in vivo, where arsenic specifically targeted solid tumors. The results indicated that RBS extract potently inhibited the tumor growth of Sarcoma-180 cell line in a dose-dependent manner. Flow cytometry and transmission electron microscopy further indicated that RBS significantly induced cell apoptosis through the inhibition of cell cycle pathway in a dose-dependent manner. Further, on RBS administration to mice, arsenic was specifically targeted to solid tumors RBS could substitute for traditional Realgar or its formula to work as a potent tool in cancer treatment.

For the traditional Chinese medicine (TCM), a prescription for a patient often contains several herbs. Some herbs are often used together in prescriptions, and these herbs can be considered as a functional group. In this paper, we propose an approach for discovering herbal functional groups from a large set of prescriptions recorded in TCM books. These functional groups are allowed to overlap with each other. Our approach is validated with a simulation study and applied to a data set containing thousands of TCM prescriptions. Copyright © 2011 John Wiley & Sons, Ltd.

Traditional chinese medicine: an update on clinical evidence.

2010-03-01

As an alternative medical system, Traditional Chinese Medicine (TCM) has been increasingly used over the last several decades. Such a consumer-driven development has resulted in introduction of education programs for practitioner training, development of product and practitioner regulation systems, and generation of an increasing interest in research. Significant efforts have been made in validating the quality, effectiveness, and safety of TCM interventions evidenced by a growing number of published trials and systematic reviews. Commonly, the results of these studies were inconclusive due to the lack of quality and quantity of the trials to answer specific and answerable clinical questions. The methodology of a randomized clinical trial (RCT) is not free from bias, and the unique features of TCM (such as individualization and holism) further complicate effective execution of RCTs in TCM therapies. Thus, data from limited RCTs and systematic reviews need to be interpreted with great caution. Nevertheless, until new and specific methodology is developed that can adequately address these methodology challenges for RCTs in TCM, evidence from quality RCTs and systematic reviews still holds the credibility of TCM in the scientific community. This article summarizes studies on TCM utilization, and regulatory and educational development with a focus on updating the TCM clinical evidence from RCTs and systematic reviews over the last decade. The key issues and challenges associated with evidence-based TCM developments are also explored.

The concept of "Quality by design" indicates that good design for the whole life cycle of pharmaceutical production enables the drug to meet the expected quality requirements. Aiming at the existing problems of the traditional Chinese medicine (TCM) industry, the TCM standardization system was put forward in this paper from the national strategic level, under the guidance by the idea of quality control in international manufacturing industry and with considerations of TCM industry's own characteristics and development status. The connotation of this strategy was to establish five interrelated systems: multi-indicators system based on tri-indicators system, quality standard and specification system of TCM herbal materials and decoction pieces, quality traceability system, data monitoring system based on whole-process quality control, and whole-process quality management system of TCM, and achieve the whole process systematic and scientific study in TCM industry through "top-level design-implement in steps-system integration" workflow. This article analyzed the correlation between the quality standards of all links, established standard operating procedures of each link and whole process, and constructed a high standard overall quality management system for TCM industry chains, in order to provide a demonstration for the establishment of TCM whole-process quality control system and provide systematic reference and basis for standardization strategy in TCM industry.

Commercial pharmaceutical herbal products have enabled people to take traditional Chinese medicine (TCM) in a convenient and accessible form. However, the quantity and quality should be additionally inspected. To address the issue, a combination of chemical and physical inspection methods were developed to evaluate the amount of an herbal formula, Xiang-Sha-Liu-Jun-Zi-Tang (XSLJZT), in clinical TCM practice. A high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS) method with electrospray ionization was developed to measure the herbal biomarkers of guanosine, atractylenolide III, glycyrrhizic acid, dehydrocostus lactone, hesperidin, and oleanolic acid from XSLJZT. Scanning electron microscopy (SEM) photographs and light microscopy photographs with Congo red and iodine-KI staining were used to identify the cellulose fibers and starch content. Furthermore, solubility analysis, swelling power test, and crude fiber analysis were contributed to measure the starch additive in pharmaceutical products. The results demonstrated large variations in the chemical components of different pharmaceutical brands. The SEM photographs revealed that the starch was oval, smooth, and granular, and that the raw herbal powder appears stripy, stretched, and filiform. The stained light microscopy photographs of all of the pharmaceutical products showed added starch and raw herbal powder as extenders. The developed chemical and physical methods provide a standard operating procedure for the quantity control of the herbal pharmaceutical products of XSLJZT.

Chemical fingerprinting is currently a widely used tool that enables rapid and accurate quality evaluation of Traditional Chinese Medicine (TCM). However, chemical fingerprints are not amenable to information storage, recognition, and retrieval, which limit their use in Chinese medicine traceability. In this study, samples of three kinds of Chinese medicines were randomly selected and chemical fingerprints were then constructed by using high performance liquid chromatography. Based on chemical data, the process of converting the TCM chemical fingerprint into two-dimensional code is presented; preprocess and filtering algorithm are also proposed aiming at standardizing the large amount of original raw data. In order to know which type of two-dimensional code (2D) is suitable for storing data of chemical fingerprints, current popular types of 2D codes are analyzed and compared. Results show that QR Code is suitable for recording the TCM chemical fingerprint. The fingerprint information of TCM can be converted into data format that can be stored as 2D code for traceability and quality control. PMID:26089936

Substantial progress has been made in China in using traditional Chinese medicine (TCM) to treat acquired immune deficiency syndrome (AIDS). Our objective was to review the latest developments in TCM treatment of AIDS in China between 2004 and 2014. We reviewed the content of original articles investigating the efficacy and safety of TCM for treating AIDS published in Chinese and English language journals. Relevant references from 2004 to 2014 were found using PubMed and the China National Knowledge Infrastructure Database. We found that TCM has been widely used for treating AIDS and its complications in China. The number of TCM studies has increased, which indicates efficacy and safety. Measures of efficacy in the reviewed articles included the alleviation of human immunodeficiency virus (HIV)-related signs and symptoms, improvements in quality of life, improvements in long-term survival, counteraction of the adverse side effects of antiviral drugs, promotion of immune reconstitution, and improvement of laboratory results. In sum, the literature indicates that TCM is safe. TCM plays an important role in the treatment of AIDS. Some studies have attempted to measure the efficacy and safety of TCM for treating AIDS, but more evidence is needed. Therefore, more research on this topic is required in the future.

While New Zealand has experienced an increase in the use of traditional Chinese medicine (TCM) based acupuncture, very little is known about the practitioners who provide this type of treatment modality. Therefore, this study was designed to identify differences associated with being a TCM practitioner in New Zealand compared to China. Ten Auckland-based TCM practitioners were individually interviewed. The interview schedule comprised of questions that were designed to identify any potential differences in practising TCM in New Zealand compared to China. Data were analysed using an inductive thematic approach. The main differences in practising between the two countries were related to the role and authority that a TCM practitioner had. This in turn resulted in differences between the conditions that were treated in these two countries. Differences in patient demography were also identified between the two countries. TCM is used as a form of alternative healthcare treatment in New Zealand for non-Chinese individuals. Acupuncture is the most utilised form of TCM treatment in New Zealand, and is predominantly used for pain management purposes. TCM treatment has been utilised by individuals from a number of different ethnic groups, reflecting the ethnic diversity of the New Zealand population.

The present study aimed to investigate the effects of Wenyangbushen formula on the mRNA and protein expression levels of vascular endothelial growth factor (VEGF), osteoprotegerin (OPG), receptor activator of nuclear factor (NF)‑κβ ligand (RANK), and RANK ligand (RANKL) in a rabbit model of steroid‑induced avascular necrosis of the femoral head (SANFH). The present study also aimed to examine the potential mechanism underlying the effect of this formula on the treatment of SANFH. A total of 136 New Zealand rabbits were randomly divided into five groups: Normal group, model group, and three groups treated with the traditional Chinese medicine (TCM), Wenyangbushen decoction, at a low, moderate and high dose, respectively. The normal group and positive control group were intragastrically administered with saline. The TCM groups were treated with Wenyangbushen decoction at the indicated dosage. Following treatment for 8 weeks, the mRNA and protein expression levels of VEGF, OPG, RANK and RANKL in the femoral head tissues were determined using reverse transcription‑quantitative polymerase chain reaction and western blot analyses, respectively. The data revealed that Wenyangbushen decoction effectively promoted the growth of bone cells, osteoblasts and chondrocytes, and prevented cell apoptosis in the SANFH. The mRNA and protein expression levels of OPG and VEGF were increased, while the levels of RANK and RANKL were reduced in the necrotic tissue of the model group, compared with those in the normal rabbits. Wenyangbushen treatment prevented these changes, manifested by an upregulation in the expression levels of VEGF and OPG, and downregulation in the expression levels of RANK and RANKL in a dose‑dependent manner. It was concluded that treatment with Wenyangbushen formula alleviated necrosis of the femoral head induced by steroids. It was observed to promote bone cell, osteoblast and chondrocyte growth, as well as prevent cell apoptosis. In addition, it upregulated the expression levels of OPG and VEGF, and inhibited the expression levels of RANK and RANKL. These results suggest the potential use of Wenyangbushen formula as a possible approach for the effective treatment of SANFH.

GP-TCM is the first EU-funded Coordination Action consortium dedicated to traditional Chinese medicine (TCM) research. One of the key deliverables of the Work Package 7 in GP-TCM was to investigate information of the existing requirements for registration of TCM products listed by global regulatory bodies. The paper aims to collate data and draw comparison of these regulations. Case studies are also presented to illustrate the problems involved in registering TCM products in different regions worldwide. A collaborative network task force was established during the early stage of the GP-TCM project and operated through exchanges, teleconferences and focused discussions at annual meetings. The task force involved coordinators, academics who are actively involved with R&D of Chinese herbal medicines, experts on monographic standards of Chinese materia medica, representatives from regulatory agencies, experts from industries in marketing Chinese medicines/herbal medicines and natural products. The co-ordinators took turns to chair teleconferences, led discussions on specific issues at AGM discussion sessions, at joint workshops with other work-packages such as WP1 (quality issues), WP3 (toxicology issues) and WP6 (clinical trial issues). Collectively the authors were responsible for collating discussion outcomes and updating written information. A global overview of regulations on herbal registration has been compiled during the three years of the consortium. The regulatory requirements for registration of herbal products in the EU and China were compared, and this is extended to other regions/countries: Africa, Australia, Brazil, Canada, Japan, Russia, South Korea, Taiwan, and the United States. A wide variation of the regulations for the categories of herbal products exists: food (functional food, novel foods, dietary food for special medical purpose, foods for particular nutritional use, food supplement); cosmetic, traditional herbal medicine products; herbal medicines for human use and veterinary use. The regulatory issues for registration of herbal products are complicated among the countries and regions worldwide. The information summarised in the text is for reference only. Some regulations which are presented in this review are still in legislation process and may change in due course. Before taking any regulatory action, readers are advised to consult current official legislation and guidance and/or to seek appropriate professional advice. The lessons learnt from global regulation of TCM will provide valuable insights for regulation of other traditional medicine such as Ayurveda and Unani medicine, as well as other forms of indigenous medicine. The WHO is well placed to co-ordinate a consultation process with the aim of putting forward suggestions for harmonisation to key regulatory agencies. Copyright © 2012 Elsevier Ireland Ltd.

China and India have a long history in the therapeutic application of botanical drugs in traditional medicine. Traditional Chinese Medicine (TCM) and Ayurveda are considered as two of the most ancient systems of medicine, with history of more than two millennia. Medicinal plants are the principal medicinal materials used in both these systems. This review discusses about the histories of Ayurveda and TCM, the common medicinal plants species, the drug processing strategies used, and the current statuses of these traditional systems of medicine (TSM). Through the views presented in this article, we aim to provide a new perspective to herbal drug researchers for expanding and improving the utilization of botanical drugs and their therapeutic applications. A bibliographic investigation of Chinese and Indian pharmacopoeias, monographs and official websites was performed. Furthermore, information was obtained from scientific databases on ethnobotany and ethno medicines. The review of Ayurveda and TCM ethno medicine indicates that both these systems have many medicinal materials in common. The studies carried out by the authors for comparison of plants from same genus from both these TSM's have been discussed to further bring focus to the utilization of "qualitatively" similar species which can be utilized and substituted for endangered or economically valued species. The overview of ancient literature and scientific findings for drugs in both these systems suggests that, the botanical drugs used in common and their processing methods can be explored further for extensive utilization in traditional medicine. This review describes the histories, common medicinal plant species, their processing methods and therapeutic applications in Ayurveda and TCM. The insights provided through this article may be used by herbal drug researchers and pharmacologists for further exploration of botanical drugs from these two traditional systems of medicine.

To describe the major factors influencing financial compensation in traditional Chinese medicine (TCM) and prioritize what TCM services should be compensated for. Two structured questionnaires-a TCM service baseline questionnaire and a service cost questionnaire-were used to collect information from TCM public hospitals on TCM services provided in certain situations and service cost accounting. The cross-sectional study examined 110 TCM services provided in four county TCM public hospitals in Shandong province. From the questionnaire data, a screening index system was established via expert consultation and brainstorming. Comprehensive evaluation of TCM services was performed using the analytic hierarchy process method. Weighted coefficients were used to measure the importance of each criterion, after which comprehensive evaluation scores for each service were ranked to indicate what services should receive priority for financial compensation. Economy value, social value, and efficacy value were the three main criteria for screening for what TCM services should be compensated for. The economy value local weight had the highest value (0.588), of which the profit sub-criterion (0.278) was the most important for TCM financial compensation. Moxibustion was tied for the highest comprehensive evaluation scores, at 0.65 while Acupuncture and Massage Therapy were tied for the second and third highest, with 0.63 and 0.58, respectively. Government and policymakers should consider offer financial compensation to Moxibustion, Acupuncture, Massage Therapy, and TCM Orthopedics as priority services. In the meanwhile, it is essential to correct the unreasonable pricing, explore compensation methods, objects and payment, and revise and improve the accounting system for the costs of TCM services.

Mist, Scott D; Wright, Cheryl L; Jones, Kim Dupree; Carson, James W

2012-01-01

Background Traditional Chinese medicine (TCM) offers various treatment modalities guided by TCM diagnoses. In the United States, acupuncture is a commonly employed TCM method for treating a variety of chronic illnesses. Three systematic reviews have been reported recently, reaching differing conclusions about the efficacy of acupuncture for the treatment of fibromyalgia (FM). Among the FM acupuncture studies considered in these reviews, none used TCM diagnosis as an inclusion/exclusion criterion or adjusted treatment based on TCM diagnosis. Overlooking TCM diagnosis may be a reason for such disparate results. Primary study objective To obtain TCM diagnoses in a sample of women meeting 1990 American College of Rheumatology criteria for FM who were recruited for a yoga study and to investigate whether there is significant variability. Methods/design Two TCM practitioners conducted baseline TCM diagnostic examinations on 56 women with FM. A consensus diagnosis was reached based on standardised history, palpation and examination. Canonical discriminate analysis identified two baseline items which predicted TCM diagnosis. Setting School of Nursing, Oregon Health & Science University. Participants Women, ages 23–75, with FM recruited to a yoga intervention study Results Three primary TCM diagnoses were found in the population: Qi and Blood Deficiency (46.4%, CI 33.0% to 60.36%), Qi and Blood Stagnation (26.8%, CI 15.8% to 40.3%), and Liver Qi Stagnation (19.6%, CI 10.2% to 32.4%). Conclusion It is likely that previous studies of FM were treating a heterogeneous study population where variable results might be expected. Future acupuncture studies should either control for TCM diagnosis or consider its usefulness as an inclusion/exclusion criterion. PMID:22026964

The bionic cultivation of medicinal plant is an ecological cultivation pattern, which is adopting ecological engineering and modern agricultural techniques to simulate the natural ecosystem of wild medicinal plant community, and has been given greater attention on the agriculture of traditional Chinese medicine (TCM). It is also the cross subject that combines Chinese traditional medicine, agronomy, horticulture, ecology, agricultural engineering and management. Moreover, it has significant technology advantages of promoting the sustainable utilization of medicinal plant resources, improving the ecological environment and harmonizing man and nature. So it's important to develop the bionic cultivation of TCM.

Traditional processes are mostly adopted in traditional Chinese medicine (TCM) preparation production and the quality of products is mostly controlled by terminal. Potential problems of the production in the process are unpredictable and is relied on experience in most cases. Therefore, it is hard to find the key points affecting the preparation process and quality control. A pattern of research and development of traditional Chinese medicine preparation process based on the idea of Quality by Design (QbD) was proposed after introducing the latest research achievement. Basic theories of micromeritics and rheology were used to characterize the physical property of TCM raw material. TCM preparation process was designed in a more scientific and rational way by studying the correlation among enhancing physical property of raw material, preparation process and product quality of preparation. So factors affecting the quality of TCM production would be found out and problems that might occur in the pilot process could be predicted. It would be a foundation for the R&D and production of TCM preparation as well as support for the "process control" of TCMIs gradually realized in the future.

To ascertain if previous findings of low levels of agreement of Traditional Chinese Medicine (TCM) pattern diagnoses made by TCM practitioners in patients with rheumatoid arthritis (RA) were a function of practitioner differences or would be replicated with a different sample of clinicians, and to examine the relationship between TCM diagnosis and herbal treatment plans. A prospective survey. General clinical research center, University of Maryland Hospital System, Baltimore, MD. Forty (40) patients with RA. PRACTITIONERS: Licensed acupuncturists with at least 5 years' experience and education in Chinese herbs. Three (3) TCM practitioners examined the same 40 RA patients separately, following the traditional Four Diagnostic Methods. Patients filled out questionnaires and physical examinations, including observations of the tongue and palpation of radial pulse, were conducted by the 3 practitioners. Each practitioner then provided both a TCM diagnosis and an herbal prescription. These diagnoses/prescriptions were examined with respect to the rate of agreement among the 3 practitioners. The average agreement with respect to the TCM diagnoses among the 3 TCM practitioners was 31.7 % (range, 27.5-35%). The degree to which the herbal prescriptions agreed with textbook recommended practice for each TCM diagnosis was 91.7% (range, 85-100%). The most commonly used TCM assessments in arriving at these diagnoses were inquiry about factors affecting pain and pulse diagnosis. No statistically significant differences were found between this study and our previous study regarding the level of agreement on TCM diagnosis. The average agreement of the diagnoses provided by 3 TCM practitioners was at the same low level as previously reported. No association was found between the diagnostic methods used and the consistency of diagnosis. Both studies, however, found a high degree of consistency between the TCM pattern diagnoses provided and the herbal treatment plans made as a result of those diagnoses.

The question of the objectivity of the clinical examination has been raised in relation to Western and non-Western medical systems. Western practitioners are often skeptical about Traditional Chinese Medicine (TCM), on the basis that its diagnostic variables and subcategories of disease appear subjective and not repeatable. We conducted a study investigating the reproducibility of individual diagnostic observations within three of the four diagnostic methods used in a TCM examination: inspection, palpation, and auscultation. Three TCM practitioners participated in the study, and examined 45 adults who had mild-to-moderate hypercholesterolemia but were otherwise healthy. Results indicated that while there are certain features of the TCM system that are highly objective and repeatable, such as detection of the presence of shen, character of breath sounds, and pulse speed, there are other features that are subjective and unreliable, such as color under the eyes and tongue body color. This poses a challenge for TCM practitioners to improve their clinical practice and demonstrates to Western medical practitioners that TCM does in part rest on a rigorous and objective empirical basis.

To respond to the human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) epidemic in China, the integration of antiretroviral therapy (ART) and traditional Chinese medicine (TCM) has important implications in health outcomes, especially in China where the use of TCM is widespread. The National Free TCM Pilot Program for HIV Infected People began in 5 provinces (Henan, Hebei, Anhui, Hubei, and Guangdong) in 2004, and quickly scaled up to 19 provinces, autonomous regions, and municipalities in China including some places with high prevalence, 26,276 adults have been treated thus far. Usually, people with HIV infection seek TCM for four main reasons: to enhance immune function, to treat symptoms, to improve quality of life, and to reduce side effects related to medications. Evidences from randomized controlled clinical trials suggested some beneficial effects of use of traditional Chinese herbal medicine for HIV infections and AIDS. More proofs from large, well-designed, rigorous trials is needed to give firm support. Challenges include interaction between herbs and antiretroviral drugs, stigma and discrimination. The Free TCM Program has made considerable progress in providing the necessary alternative care and treatment for HIV-infected people in China, and has strong government support for continued improvement and expansion, establishing and improving a work mechanism integrating Chinese and Western medicines.

Traditional Chinese medicine (TCM) is an important part of the treatment of primary liver cancer (PLC) in China; however, the current instructions for the integrative use of traditional Chinese and Western medicine for PLC are mostly based on expert opinion. There is no evidence-based guideline for clinical practice in this field. Therefore, the Shanghai Association of Chinese Integrative Medicine has established a multidisciplinary working group to develop this guideline, which focuses on the most important questions about the use of TCM during PLC treatment. This guideline was developed following the methodological process recommended by the World Health Organization Handbook for Guideline Development. Two rounds of questionnaire survey were performed to identify clinical questions; published evidence was searched; the Grading of Recommendations Assessment, Development and Evaluation approach was used to evaluate the body of evidence; and recommendations were formulated by combining the quality of evidence, patient preferences and values, and other risk factors. The guideline was written based on the Reporting Items for Practice Guidelines in Healthcare tool. This guideline contains 10 recommendations related to 8 questions, including recommendations for early treatment by TCM after surgery, TCM combined with transcatheter arterial chemoembolization for advanced PLC, TCM drugs for external use, and acupuncture and moxibustion therapy.

A Disturbance Rejection Framework for the Study of Traditional Chinese Medicine

PubMed Central

Sun, Yan

2014-01-01

The traditional Chinese medicine (TCM) is explained in the language of engineering cybernetics (EC), an engineering science with the tradition of rigor and long history of practice. The inherent connection is articulated between EC, as a science of interrelations, and the Chinese conception of Wuxing. The combined cybernetic model of Wuxing seems to have significant explaining power for the TCM and could potentially facilitate better communications of the insights of the TCM to the West. In disturbance rejection, an engineering concept, a great metaphor, is found to show how the TCM is practiced, using the liver cancer pathogenesis and treatment as a case study. The results from a series of experimental studies seem to lend support to the cybernetic model of Wuxing and the principles of disturbance rejection. PMID:24995034

Allergic rhinitis (AR) is a common allergic disorder in children, some of whom seek complementary treatments, including acupuncture and Chinese herbs. Little, however, is known about the treatment of pediatric AR with traditional Chinese medicine (TCM). To characterize TCM use in pediatric AR, we conducted a nationwide population-based study. We screened one million randomly sampled beneficiaries of the National Health Insurance Program in Taiwan from 2002 to 2010 to identify children <18 years of age with newly diagnosed allergic rhinitis (ICD-9 code 477.9). The subjects were categorized according to their use of TCM. We identified 97,401 children newly diagnosed with AR for inclusion in the study. Among these children, 63.11% (N=61,472) had used TCM. There were significantly more TCM users than non-users among school-age children and adolescents (P<0.001). Most (99.1%) pediatric TCM users received Chinese herbal remedies (99.1%); only 0.9% received acupuncture or manipulative therapies. Xin-Yi-Qing-Fei-Tang (Magnolia Flower Lung-Clearing Decoction) was the most frequently prescribed TCM formulation (23.44%), and the most commonly prescribed single herb was Chan-Tui (Periostracum cicadae; 13.78%). Regarding syndrome differentiation (ZHENG) according to TCM theory, prescriptions for the Cold Syndrome exceeded those for the Hot Syndrome throughout the year in Taiwan. We found that approximately two-thirds of pediatric AR patients were prescribed TCM treatments in Taiwan. Further research is warranted to examine the efficacy and safety of TCM for pediatric AR patients. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The safety and effectiveness of traditional Chinese medicine (TCM) in clinical practice is directly related to the quality of TCM. And, the quality control of TCM is a pivotal issue to the quality of TCM, but also an obstacle impeding the modernization of TCM. The purpose of this work is to compile and develop a strategy based on discrimination and identification of quality markers (Q-markers) for quality control of TCM. Mainly established by seven variables derived from four dimensions including content, stability, pharmacokinetics and pharmacology, the 'Spider-web' mode was undertaken to assess the Q-marker property of candidate compounds originated from TCM by taking regression area (A) and coefficient variation (CV) of the tested compounds into account. The importance index (ImI), ImI = A × 1/CV, was suggested to focus Q-markers. The compounds with larger regression area (A) and less coefficient variation (CV) are preferentially adopted as Q-markers, which should possess the satisfactory properties of content, stability, pharmacokinetics and pharmacological activity. To the contrary, the compounds are excluded on the grounds of the unsatisfactory Q-markers' property, less regression area (A) and larger coefficient variation (CV), which cannot represent the quality of TCM. The 'Spider-web' mode can filter out the redundant constituents and focus on the key indexes of quality control - Q-markers. The screened Q-markers possess the optimal integrated properties of content, stability, pharmacokinetics and pharmacology among the numerous and complicated ingredients of TCM, which can comprehensively characterize inherent quality of TCM. In summary, the novel strategy established in this work provides a valuable perspective for the quality control of TCM. Copyright © 2017 Elsevier GmbH. All rights reserved.

Treatment of pulmonary fibrosis by traditional Chinese medicine (TCM) has accumulated important experience. Our interest is in exploring the medication regularity of contemporary Chinese medical specialists treating pulmonary fibrosis. Through literature search, medical records from TCM experts who treat pulmonary fibrosis, which were published in Chinese and English medical journals, were selected for this study. As the object of study, a database was established after analysing the records. After data cleaning, the rules of medicine in the treatment of pulmonary fibrosis in medical records of TCM were explored by using data mining technologies such as frequency analysis, association rule analysis, and link analysis. A total of 124 medical records from 60 doctors were selected in this study; 263 types of medicinals were used a total of 5,455 times; the herbs that were used more than 30 times can be grouped into 53 species and were used a total of 3,681 times. Using main medicinals cluster analysis, medicinals were divided into qi-tonifying, yin-tonifying, blood-activating, phlegm-resolving, cough-suppressing, panting-calming, and ten other major medicinal categories. According to the set conditions, a total of 62 drug compatibility rules have been obtained, involving mainly qi-tonifying, yin-tonifying, blood-activating, phlegm-resolving, qi-descending, and panting-calming medicinals, as well as other medicinals used in combination. The results of data mining are consistent with clinical practice and it is feasible to explore the medical rules applicable to the treatment of pulmonary fibrosis in medical records of TCM by data mining.

The decision by the patients to disclose traditional and complementary medicine (TCM) use to their doctor is an important area to be explored. This study aimed to determine the disclosure of TCM use and its associated factors to medical doctor among primary care clinic attendees in Kuching Division, Sarawak. It was a cross-sectional study using questionnaire, interviewer administered questionnaire. A total of 1130 patients were screened with 80.2% reporting using TCM. Logistic regression analysis revealed that being female (AOR = 3.219, 95% CI: 1.385, 7.481), perceived benefits that TCM can prevent complication of illness (AOR = 3.999, 95% CI: 1.850, 8.644) and that TCM is more gentle and safer (AOR = 4.537, 95% CI: 2.332, 8.828), perceived barriers of not having enough knowledge about TCM (AOR = 0.530, 95% CI: 0.309, 0.910), patient dissatisfaction towards healthcare providers being too business-like and impersonal (AOR = 0.365, 95% CI: 0.199, 0.669) and paying more for healthcare than one can afford (AOR = 0.413, 95% CI: 0.250, 0.680), and accessibility of doctors (AOR = 3.971, 95% CI: 2.245, 7.023) are the predictors of disclosure of TCM use. An open communication between patients and doctor is important to ensure safe implementation and integration of both TCM and medical treatment.

Chinese patent medicines for orthopedics are among the hotspot and difficulty in the rational medication of traditional Chinese medicine (TCM), because they mostly contain toxic medicinal herbs and oriented to special patients. According to the hospital pharmacy practices and the therapeutic theories of TCM, this paper focused on a novel model of rational drug use of Chinese patent medicine for orthopedics based on the principles of ″syndrome-dosage-toxicity differentiation″. We also proposed relevant specifications for guiding their clinical use. Firstly, we proposed a list of the primary clinical application characteristics for rational drug use of orthopedic TCMs, including the syndromes of patient, the dosage of medicine and the toxic ingredients in medicine. Secondly, a database was established for recording the package inserts of all of the 81 orthopedic patent medicines in our hospital, and 2 000 retrospective recipes were analyzed for looking for the high-frequency medicines and common irrational factors. Then clinical case reports involving the adverse reactions and side effects of related drugs were searched from CNKI, VIP and WanFang databases. Then the key information for rational application of each medicine was extracted from these resources and some survey questionnaires. Finally, we established a guide named instructions for clinical use of orthopedic Chinese patient medicines (ICUOCPM) after the discusstion with experts. According to the effect after the practice in hospital for 2 months, the proposed principles of ″syndrome-dosage-toxicity differentiation″ in this paper were believed to be the core elements and the most important clinical monitoring points in TCM for orthopedic patents. It would provide innovative ideas, theoretical guarantee and data support for the development of TCM clinical pharmacy. Copyright© by the Chinese Pharmaceutical Association.

Alcohol has long been used as a daily beverage in China and around the world. It is a medicinal substance with various biological activities. In fact, alcohol has played an important role in the development of traditional Chinese medicine (TCM), within which it is considered as the earliest exhilarant and anaesthetic. Yet, as a substance with great potency of misuse and addiction, the consumption of alcohol can lead to serious damage to individual health and the society. Over the past 20 years, alcohol abuse or alcoholism has become an increasing social problem in China along with the rapid economic development. China, the country of origin for TCM, has accumulated abundant clinical experience in the treatment of alcoholism with its ancient medicine. In the present research, we have summarized clinical and primary studies concerning various remedies of TCM for alcohol abuse, including herbal components (such as Kudzu/Pueraria Lobata, Pediculus melo, Hypericumpperforatum L.), decoctions and acupuncture.

Chinese medicine and biomodulation in cancer patients—Part one

2008-01-01

Traditional Chinese Medicine (tcm) may be integrated with conventional Western medicine to enhance the care of patients with cancer. Although tcm is normally implemented as a whole system, recent reductionist research suggests mechanisms for the effects of acupuncture, herbs, and nutrition within the scientific model of biomedicine. The health model of Chinese medicine accommodates physical and pharmacologic interventions within the framework of a body–mind network. A Cartesian split does not occur within this model, but to allow for scientific exploration within the restrictions of positivism, reductionism, and controls for confounding factors, the components must necessarily be separated. Still, whole-systems research is important to evaluate effectiveness when applying the full model in clinical practice. Scientific analysis provides a mechanistic understanding of the processes that will improve the design of clinical studies and enhance safety. Enough preliminary evidence is available to encourage quality clinical trials to evaluate the efficacy of integrating tcm into Western cancer care. PMID:18317584

The current modes of experience inheritance from famous specialists in traditional Chinese medicine (TCM) include master and disciple, literature review, clinical-epidemiology-based clinical research observation, and analysis and data mining via computer and database technologies. Each mode has its advantages and disadvantages. However, a scientific and instructive experience inheritance mode has not been developed. The advent of the big data era as well as the formation and practice accumulation of the TCM clinical research paradigm in the real world have provided new perspectives, techniques, and methods for inheriting experience from famous TCM specialists. Through continuous exploration and practice, the research group proposes the innovation research mode based on the real-world TCM clinical research paradigm, which involves the inheritance and innovation of the existing modes. This mode is formulated in line with its own development regularity of TCM and is expected to become the main mode of experience inheritance in the clinical field.

The foreign exchange activities of traditional Chinese medicine are conducted under the guidance of the policy of the CPC and Chinese government. After the carrying out of the reform and opening-up policy, foreign exchange policy of TCM has experienced the process of growing up from nothing, from less to more, and from coarse to fine, which is closely related to our country's foreign policy, the cause of Chinese medicine development, and urgent need of international communication. In the three decades after the reform and opening-up policy, the formulation of foreign exchange policy of TCM can be divided into three stages: viz., inclusion in the framework of national foreign policy (1978-1985), embodiment in the policy of developing TCM cause (1986-1996), and appearance in the special policy of foreign exchange of Chinese medicine (since 1997). From the development process of these policies, the development of each policy gradually complies with the process of the development of the times, with its contents basically in line with the requirements of the times. The implementation of some policies promotes the foreign exchanges and cooperation of Chinese medicine.

Drugs are exogenous compounds for human bodies, and will be metabolized by many enzymes after administration. CYP450 enzyme, as a major metabolic enzyme, is an important phase I drug metabolizing enzyme. In human bodies, about 75% of drug metabolism is conducted by CYP450 enzymes, and CYP450 enzymes is the key factor for drug interactions between traditional Chinese medicine( TCM) -TCM, TCM-medicine and other drug combination. In order to make clear the interaction between metabolic enzymes and TCM metabolism, we generally chose the enzymatic activity as an evaluation index. That is to say, the enhancement or reduction of CYP450 enzyme activity was used to infer the inducing or inhibitory effect of active ingredients and extracts of traditional Chinese medicine on enzymes. At present, the common method for measuring metabolic enzyme activity is Cocktail probe drugs, and it is the key to select the suitable probe substrates. This is of great significance for study drug's absorption, distribution, metabolism and excretion (ADME) process in organisms. The study focuses on the interaction between TCMs, active ingredients, herbal extracts, cocktail probe substrates as well as CYP450 enzymes, in order to guide future studies.

Traditional and complementary medicine (T&CM) plays an integral role in providing health care worldwide. It is based on sound fundamental principles and centuries of practices. This study compared traditional Indian medicine (TIM) and traditional Korean medicine (TKM) basing on data obtained from peer reviewed articles, respective government institutional reports and World Health Organization reports. Despite the fact that TIM and TKM have individual qualities that are unique from each other including different histories of origin, they share a lot in common. Apart from Homeopathy in TIM, both systems are hinged on similar principle of body constitutional-based concept and similar disease diagnosis methods of mainly auscultation, palpation, visual inspection, and interrogation. Similarly, the treatment methods of TIM and TKM follow similar patterns involving use of medicinal herbs, moxibustion, acupuncture, cupping, and manual therapy. Both T&CM are majorly practiced in well-established hospitals by T&CM doctors who have undergone an average of 6-7 years of specialized trainings. However, unlike TIM which has less insurance coverage, the popularity of TKM is majorly due to its wide national insurance coverage. These two medical traditions occupy increasingly greater portion of the global market. However, TIM especially Ayurveda has gained more global recognition than TKM although the emergence of Sasang Constitutional Medicine in TKM is beginning to become more popular. This comparative analysis between TIM and TKM may provide vital and insightful contribution towards constitutional-based concept for further development and future studies in T&CM.

Exploring the Ligand-Protein Networks in Traditional Chinese Medicine: Current Databases, Methods, and Applications

Zhao, Mingzhu; Wei, Dong-Qing

2013-01-01

The traditional Chinese medicine (TCM), which has thousands of years of clinical application among China and other Asian countries, is the pioneer of the “multicomponent-multitarget” and network pharmacology. Although there is no doubt of the efficacy, it is difficult to elucidate convincing underlying mechanism of TCM due to its complex composition and unclear pharmacology. The use of ligand-protein networks has been gaining significant value in the history of drug discovery while its application in TCM is still in its early stage. This paper firstly surveys TCM databases for virtual screening that have been greatly expanded in size and data diversity in recent years. On that basis, different screening methods and strategies for identifying active ingredients and targets of TCM are outlined based on the amount of network information available, both on sides of ligand bioactivity and the protein structures. Furthermore, applications of successful in silico target identification attempts are discussed in detail along with experiments in exploring the ligand-protein networks of TCM. Finally, it will be concluded that the prospective application of ligand-protein networks can be used not only to predict protein targets of a small molecule, but also to explore the mode of action of TCM.

2015-01-01

Traditional Chinese medicine (TCM) has played a positive role in the management of hepatocarcinoma. Hepatocarcinoma patients may present Qi-stagnation, damp-heat, blood stasis, Qi-deficiency, Yin-deficiency and other TCM syndromes (Zheng). Modern treatments such as surgery, transarterial chemoembolization (TACE) and high intensity focus ultrasound treatment would influence the manifestation of TCM syndromes. Herbs with traditional efficacy of tonifying Qi, blood and Yin, soothing liver-Qi stagnation, clearing heat and detoxifying and dissolving stasis, have been demonstrated to be potent to prevent hepatocarcinogenesis. TCM has been widely used in all aspects of integrative therapy in hepatocarcinoma, including surgical resection, liver transplantation, TACE, local ablative therapies and even as monotherapy for middle-advanced stage hepatocarcinoma. Clinical practices have confirmed that TCM is effective to alleviate clinical symptoms, improve quality of life and immune function, prevent recurrence and metastasis, delay tumor progression, and prolong survival time in hepatocarcinoma patients. The effective mechanism of TCM against hepatocarcinoma is related to inducing apoptosis, autophagy, anoikis and cell senescence, arresting cell cycle, regulating immune function, inhibiting metastasis and angiogenesis, reversing drug resistance and enhancing effects of chemotherapy. Along with the progress of research in this field, TCM will contribute more to the prevention and treatment of hepatocarcinoma. PMID:26019736

Erectile dysfunction (ED) is a common sexual problem affecting many men irrespective of cultures, beliefs and nationalities. While medical therapy for ED has been revolutionized by the advent of oral phosphodiesterase type 5 inhibitors and intracavernosal injection of vasoactive agents, recent technological advances such stem cell therapy, low intensity shock wave and newer generation of penile prosthesis implant offer hope to men who do not respond to conventional medical therapy. In contrast, traditional and complementary medicine (TCM) focuses on the restoration and better overall bodily regulation with the use of various herbal and animal products as well as exercises to invigorate qi (energy) in vital organs. Western medicine involves an analysis of ED symptom and underlying causes that contribute to ED, while TCM emphases the concept of holism and harmonization of body organs to achieve natural sexual life. The following article reviews our current understanding regarding the philosophical approach, and evaluates the evidence surrounding various ED therapies between mainstream Western Medicine and TCM.

Influenced by national nihilism in modern times, many people do not recognize Traditional Chinese Medicine (TCM). Its economic value and social economic support played an important role in the victory of the fight for TCM in the period of the Republic of China. Meanwhile, the education, clinical practice and administration of TCM during the period of Republic of China were all under the constraint of economy. Analysis of the economy's impact on the development of TCM is of practical value. Related to the national economy and the people's livelihood, TCM could be considered both as an important component of national economy and as a state investment. Only when the relationship between TCM and social economy is emphasized and handled well, could the national health industry be rapidly developed.

Chinese proprietary medicine in Singapore: regulatory control of toxic heavy metals and undeclared drugs.

2000-11-01

Traditional Chinese medicine (TCM) is gaining popularity as a form of complementary and alternative medicine. Reports of efficacy of TCM are increasing in numbers. TCM includes both crude Chinese medicinal materials (plants, animal parts and minerals) and Chinese proprietary medicine (CPM) [final dosage forms]. Despite the belief that CPM and herbal remedies are of natural origin, unlike Western medicine, and are hence safe and without many adverse effects, there have been numerous reports of adverse effects associated with herbal remedies. Factors affecting the safety of herbal medicines include intrinsic toxicity, adulteration, substitution, contamination, misidentification, lack of standardisation, incorrect preparation and/or dosage and inappropriate labelling and/or advertising. Hence, new regulations on the control of CPM were enforced in Singapore with effect from 1 September 1999. These include licensing and labelling requirements, as well as control of microbial contamination. This article also reviews reports of excessive toxic heavy metals and undeclared drugs in CPM in Singapore between 1990 and 1997. The names, uses, toxic heavy metal or drug detected and the year of detection are tabulated. Information on the brand or manufacturer's name are provided whenever available. The public and healthcare professionals should be better informed of the basic concept of TCM and its usefulness, as well as the potential adverse effects associated with its use. Greater control over the safety and quality of CPM could be achieved through good manufacturing practice, regulatory control, research, education, reporting usage of Chinese medicine (as in drug history) as well as reporting of adverse events.

Traditional Chinese Medical (TCM) journals have been playing an important role in scholarly communication in China. However, the information in those periodicals was not enough for international readers. This study aims to provide an overview of TCM journals in China. TCM journals currently published in mainland China were identified from Chinese databases and journal subscription catalogs. Data on publication start year, publishing region, language, whether core journals, whether indexed in famous international databases, with/without accessible URL were investigated, and subjects of journals were categorized. One hundred and forty-nine (149) TCM journals are currently published in mainland China; 88.59% of them are academic journals. The subjects of those journals are various, ranging from the general TCM, integrative medicine, herbal medicines, to veterinary TCM. The publishing areas are distributed in 27 regions, with Beijing having the most TCM journals published. One hundred and forty-two (142) of those periodicals are in Chinese, while 4 are also in English, and 3 in other languages. Only 8 TCM journals were recognized as core journals, and 5 were identified as both core journals and journals with high impacted articles by all evaluation systems in China. A few of the TCM journals from mainland China are indexed in PubMed/MEDLINE (10), EMBASE (5), Biological Abstracts (2), or AMED (1). Online full-text Chinese databases CJFD, COJ, and CSTPD cover most of TCM the journals published in the country. One hundred (100) TCM journals have accessible URLs, but only 3 are open access with free full texts. Publication of TCM journals in China has been active in academic communication in the past 20 years. However, only a few of them received recognized high evaluation. English information from them is not sufficient. Open access is not extensively acceptable. The accessibility of those journals to international readers needs to be improved.

Objective Traditional Chinese Medicine (tcm) is used in China as part of the treatment for non-small-cell lung cancer (nsclc) and often includes prescription of herbal therapy based on syndrome differentiation. Studies of various Astragalus-based Chinese medicines combined with platinum-based chemotherapy in the treatment of lung cancer are popular in East Asia, particularly in China. The aim of the present study was to perform a systematic review and meta-analysis comparing platinum-based chemotherapy alone with platinum-based chemotherapy plus Astragalus-based Chinese botanicals, with and without prescription based on syndrome differentiation, as first-line treatment for advanced nsclc. Methods We searched the Chinese Biomedical Literature database, the China National Knowledge Internet, the VIP Chinese Science and Technology Periodicals Database, PubMed, embase, the Cochrane databases, and abstracts presented at meetings of the American Society of Clinical Oncology, the World Conference on Lung Cancer, the European Society for Medical Oncology, and the Chinese Society of Clinical Oncology for all eligible studies. Endpoints were overall survival; 1-year, 2-year, and 3-year survival rates; performance status; overall response rate; and grade 3 or 4 adverse events. Subgroup analyses based on herbal formulae individualized using syndrome differentiation or on oral or injection patent medicines were performed using the Stata software application (version 11.0: StataCorp LP, College Station, TX, U.S.A.) and a fixed-effects or random-effects model in case of heterogeneity. Results are expressed as a hazard ratio (hr) or relative risk (rr), with corresponding 95% confidence intervals (cis). Results Seventeen randomized studies with scores on the Jadad quality scale of 2 or more, representing 1552 patients, met the inclusion criteria. Compared with platinum-based chemotherapy alone, the addition of Astragalus-based tcm to chemotherapy was associated with significantly increased overall survival (hr: 0.61; 95% ci: 0.42 to 0.89; p = 0.011); 1-year (rr: 0.73; 95% ci: 0.65 to 0.82; p < 0.001), 2-year (rr: 0.3344; 95% ci: 0.237 to 0.4773; p < 0.001), and 3-year survival rates (rr: 0.30; 95% ci: 0.17 to 0.53; p < 0.001); performance status (rr: 0.43; 95% ci: 0.34 to 0.55; p < 0.001); and tumour overall response rate (rr: 0.7982; 95% ci: 0.715 to 0.89; p < 0.001). Subgroup analyses indicated that Astragalus herbal formulae given based on syndrome differentiation were more effective than Astragalus-based oral and injection patent medicines. Side effects—including anemia, neutropenia, thrombocytopenia, fatigue, poor appetite, nausea, and vomiting—were significantly more frequent with platinum-based chemotherapy alone than when platinum-based chemotherapy was combined with Astragalus-based tcm. Conclusions Astragalus-based Chinese botanical therapy, especially when based on syndrome differentiation, is associated with increased efficacy of platinum-based chemotherapy and decreased platinum-derived toxicities for patients with advanced nsclc.

Infections caused by Candida albicans, often refractory and with high morbidity and mortality, cause a heavy burden on the public health while the current antifungal drugs are limited and are associated with toxicity and resistance. Many plant-derived molecules including compounds isolated from traditional Chinese medicine (TCM) are reported to have antifungal activity through different targets such as cell membrane, cell wall, mitochondria, and virulence factors. Here, we review the recent progress in the anti-Candida compounds from TCM, as well as their antifungal mechanisms. Considering the diverse targets and structures, compounds from TCM might be a potential library for antifungal drug development. PMID:29445739

Alternative Therapies for Diabetes: A Comparison of Western and Traditional Chinese Medicine (TCM) Approaches.

Xiao, Eric; Luo, Luguang

2017-05-18

Across the world, the economic and health costs of diabetes are rising at an alarming rate. Each year in the United States, billions of dollars are spent on T2 Diabetes mellitus (T2DM) treatments, but such treatments are not always effective and can lead to adverse events. Many pharmacological treatments exist to control the primary and secondary symptoms of T2DM, but these medications are not always efficacious, do little to treat secondary T2DM symptoms, and often carry adverse side effects. Traditional Chinese Medicine (TCM) is a form of alternative medicine that is becoming appealing to western healthcare systems because of its comprehensive, holistic approach to managing T2DM patients. Works across TCM printed texts, clinical trial databases, medical association practice guidelines, and the existing literature on TCM and western diabetes treatments (in print and online) are reviewed. Conventional pharmaceutical therapies for T2DM are not efficacious enough to maintain satisfactory blood glucose levels for all patients, and even patients who maintain stable blood glucose levels may still suffer from secondary T2DM symptoms as well as from the side effects of their medications. TCM therapies have demonstrated promising results in T2DM clinical studies without causing the types of side effects associated with standard pharmaceutical treatments. In addition, the economic burden of TCM diabetes treatments on patients and payers is oftentimes less than that of pharmaceutical regimens. TCM approaches can be a viable alternative approach to treatment in the modern U.S. healthcare landscape, but a number of obstacles impede its assimilation into western health systems.

The diagnostic framework and clinical reasoning process in Chinese medicine emphasizes the contextual and qualitative nature of a patient's illness. Chinese medicine assessment data may help interpret clinical outcomes. As part of a study aimed at assessing the validity and improving the inter-rater reliability of the Chinese diagnostic process, a structured assessment instrument was developed for use in clinical trials of acupuncture and other Chinese medical therapies. To foster collaboration and maximize resources and information, an interdisciplinary advisory team was assembled. Under the guidance of two group process facilitators, and in order to establish whether the assessment instrument was consistent with accepted Chinese medicine diagnostic categories (face validity) and included the full range of each concept's meaning (content validity), a panel of Traditional Chinese Medicine (TCM) expert clinicians was convened and their responses were organized using the Delphi process, an iterative, anonymous, idea-generating and consensus-building process. An aggregate rating measure was obtained by taking the mean of mean ratings for each question across all 10 experts. Over three rounds, the overall rating increased from 7.4 (SD = 1.3) in Round 1 to 9.1 (SD = 0.5) in Round 3. The level of agreement among clinicians was measured by a decrease in SD. The final instrument TEAMSI-TCM (Traditional East Asian Medicine Structured Interview, TCM version) uses the pattern differentiation model characteristic of TCM. This modular, dynamic version was specifically designed to assess women, with a focus on gynecologic conditions; with modifications it can be adapted for use with other populations and conditions. TEAMSI-TCM is a prescriptive instrument that guides clinicians to use the proper indicators, combine them in a systematic manner, and generate conclusions. In conjunction with treatment manualization and training it may serve to increase inter-rater reliability and inter-trial reproducibility in Chinese medicine clinical trials. Testing of the validity and reliability of this instrument currently is underway.

No previous studies have evaluated the effect of traditional Chinese medicine (TCM) treatment on the survival of patients with systemic lupus erythematosus (SLE). Hence, in this study, we determined whether TCM treatment affects the survival of SLE patients. This nationwide population-based retrospective cohort study assessed 23,084 patients newly diagnosed with SLE between 1999 and 2009, using the database of the Taiwan National Health Insurance program. Among these patients, 9267 (40.15%) used TCM for SLE treatment and exhibited a significantly decreased risk of death [hazard ratio (HR) = 0.73; 95% confidence interval (CI): 0.68-0.78], with multivariate adjustment, compared with those without TCM use. A similar significant protective effect of TCM use was found across various subgroups of comorbidities. TCM use 1 year before diagnosis also reduced the risk of death. Our study findings indicated that Zhi Bo Di Huang Wan (HR = 0.54; 95% CI: 0.32-0.91), Jia Wei Xiao Yao San (HR = 0.35; 95% CI: 0.16-0.73), Liu Wei Di Huang Wan (HR = 0.51; 95% CI: 0.28-0.93), Gan Lu Yin (HR = 0.40; 95% CI: 0.17-0.96), and Yin Qiao San (HR = 0.22; 95% CI: 0.05-0.86) were the most effective TCM agents that improved survival. This nationwide retrospective cohort study provided information that combined therapy with TCM may improve the survival in SLE patients. This study also suggests that TCM may be used as an integral element of effective therapy for SLE. Copyright © 2016 Elsevier Inc. All rights reserved.

At the beginning of the ancient "Silk Road", traditional Chinese medicine resources (TCM resources) have long been integrated into it, and it was once the "important part" of the ancient "Silk Road" in Chinese history, benefited from this, the political connections was strengthened, the economic and trade was developed, and Chinese medicine culture was spread. Before Qing Dynasty, people took out the "silk" and brought back "herbs" on the "Silk Road", which enriched China's medicinal resources. While in the later Qing Dynasty and the period of the Republic of China, more scientific and technological methods were brought back from abroad, and this in turn enriched the medical research methods. With more than 2 000 years' development, China's boundaries have changed countless times, therefore the word "Foreign" has different meanings in different historical periods. The import, development and utilization of foreign TCM resources is different in different historical periods, at present, with the continuous enhancement of China's comprehensiv national strength，especially the "Belt And Road" strategy, the communication and import of TCM resources with countries that participating in the "Belt and Road" initiativ became much easier. In order to actively respond to the "Belt and Road" initiative promote the development and utilization of foreign medicinal resources; serve people from the countries participating in the "Belt and Road" initiative we sorted out the foreign TCM resources from different periods in ancient and modern China, and based on this, we proposed the strategy of import of foreign TCM resources under the new situation, those are: "three levels, four steps, one support and one key". And "three levels" refers to intelligence collection level, field investigation level, scientific research level, "Four steps" refers to the original identification research, safety evaluation research, functional positioning research and medicinal properties research; "One support" refers to relying on overseas Chinese or Chinese enterprises with working foundation and network resources, "One key" refers to the protection of the intellectual property rights of foreign TCM resources at the policy level and to mobilize the initiative of all parties.

Emerging clinical usage and pharmacological effects have been achieved in using Rehmanniae Radix either singly or in combination with other herbs to treat skeletal diseases in traditional Chinese medicine (TCM) in the recent years. This study is aimed to provide a comprehensive review about the historical TCM interpretation of the action of Rehmanniae Radix in osteoporosis, its usage in clinical trials and osteoporotic models, its main phytochemical constituents, and its pharmacokinetics. Several databases included PubMed, China Knowledge Resource Integrated Database, China Science and Technology Journal Database, National Science and Technology Library and the Web of Science Database were consulted to locate the publications pertaining to Rehmanniae Radix. The initial inquiry was conducted for the presence of the following terms combinations in the abstracts: Rehmanniae Radix, Dihuang, phytochemistry, pharmacokinetics, osteoporosis, bone, osteoclast and osteoblast. About 330 research papers and reviews were consulted. In TCM, Rehmanniae Radix exerts the anti-osteoporotic effect via regulating the functions of kidney and liver as well as improving blood circulation. 107 clinical trials are identified that used Rehmanniae Radix in combination with other herbs to treat post-menopausal, senile and secondary osteoporosis. Most of the clinical trials are characterized by high efficacy and no obvious adverse effects. However, the efficacies of these clinical trials are limited because of small patient sample size, short treatment duration and poor clinical design. In addition, TCM herbs under the clinical study are not clear because of a lack of standardization and authentication. The pharmacokinetics data demonstrate that the ingredients of Rehmanniae Radix are widely distributed after administration, and that catalpol and ajugol as well as acetoside are supposed to be the active constituents. More than 140 individual compounds have been currently isolated from this plant and reported to show pleiotropic effects on various diseases. Rehmanniae Radix displays bone protecting features in the osteoporosis models via the delicate balance between osteoclastogenesis and osteoblastogenesis through single herb extracts and its isolated compounds. The successful inclusion of Rehmanniae Radix in clinical trials and preclinical studies for the management of osteoporosis has attracted rising attentions for identifying potential anti-osteoporotic candidates from this plant and clinical existing TCM formulas, which will further speed up anti-osteoporosis drug discovery processes. Properly designed and well controlled prospective studies are still needed to further demonstrate bone protective actions and safe use of this herb and its ingredients.

Comparison of Patient Health History Questionnaires Used in General Internal and Family Medicine, Integrative Medicine, and Complementary and Alternative Medicine Clinics.

PubMed

Laube, Justin G R; Shapiro, Martin F

2017-05-01

Health history questionnaires (HHQs) are a set of self-administered questions completed by patients prior to a clinical encounter. Despite widespread use, minimal research has evaluated the content of HHQs used in general internal medicine and family medicine (GIM/FM), integrative medicine, and complementary and alternative medicine (CAM; chiropractic, naturopathic, and Traditional Chinese Medicine [TCM]) clinics. Integrative medicine and CAM claim greater emphasis on well-being than does GIM/FM. This study investigated whether integrative medicine and CAM clinics' HHQs include more well-being content and otherwise differ from GIM/FM HHQs. HHQs were obtained from GIM/FM (n = 9), integrative medicine (n = 11), naturopathic medicine (n = 5), chiropractic (n = 4), and TCM (n = 7) clinics in California. HHQs were coded for presence of medical history (chief complaint, past medical history, social history, family history, surgeries, hospitalizations, medications, allergies, review of systems), health maintenance procedures (immunization, screenings), and well-being components (nutrition, exercise, stress, sleep, spirituality). In HHQs of GIM/FM clinics, the average number of well-being components was 1.4 (standard deviation [SD], 1.4) compared with 4.0 (SD, 1.1) for integrative medicine (p < 0.01), 3.2 (SD, 2.1) for naturopathic medicine (p = 0.04), 2.0 (SD, 1.4) for chiropractic (p = 0.54), and 2.0 (SD, 1.5) for TCM (p = 0.47). In HHQs of GIM/FM clinics, the average number of medical history components was 6.4 (SD, 1.9) compared with 8.3 (SD, 1.2) for integrative medicine (p = 0.01), 9.0 (SD, 0) for naturopathic medicine (p = 0.01), 7.1 (SD, 2.8) for chiropractic (p = 0.58), and 7.1 (SD, 1.7) for TCM (p = 0.41). Integrative and naturopathic medicine HHQs included significantly more well-being and medical history components than did GIM/FM HHQs. Further investigation is warranted to determine the optimal HHQ content to support the clinical and preventive health goals of general internal medicine, family medicine, integrative medicine, and CAM practices.

Traditional Chinese Medicine (TCM) is a popular form of ethnomedicine in the UK, and is accessed by Western, Chinese and other ethnic groups. The current regulatory regime does not effectively protect the public against poor-quality and unsafe TCMs. Understanding ethnopharmacological information on how TCM is promoted and practiced may help to inform initiatives aimed at ensuring the safe use of TCMs in the UK, and put laboratory-based ethnopharmacological investigations of TCMs in a broader context. This study aimed to examine the characteristics and practices of TCM retail outlets in London, UK, and to identify factors relevant to the safe use of TCM in the UK. TCM retail outlets ('shops') in London, UK, were identified using a systematic approach. A structured questionnaire including questions on shop business type was used to recruit participant shops. Shops consenting to participate were visited within six weeks of providing consent. A piloted semi-structured questionnaire on shop characteristics was used for data collection following observation. The British National Formulary 53 was used to classify medical conditions/uses for TCMs promoted in the shops. Data were stored and analysed using MS Access 2003, MS Excel 2003 and SPSS 13. In total, 54 TCM shops in London were identified, of which 94% offered TCM consultations with a TCM practitioner. Detailed characteristics were described within 35/50 shops that gave consent to observing their premises. Most shops labelled and displayed over 150 Chinese Materia Medica (CMMs; crude materials, particularly herbs) for dispensing after consultations with a TCM practitioner. Medical conditions/uses and Patent Chinese Medicines (PCMs) were commonly promoted. In total, 794 occurrences of 205 different medical conditions/uses (median=32, QL=19, QU=48) were identified. These conditions/uses most commonly related to the following therapeutic systems: central nervous system (160/794, 20.2%); musculoskeletal and joint disease (133/794, 16.8%); obstetrics, gynaecology, and urinary-tract disorders (122/794, 15.4%); skin (102/794, 12.9%); gastrointestinal system (62/794, 7.8%). Specific conditions/uses that were frequently promoted included eczema (19/23 shops, 82.6%), arthritis (18/23, 78.3%), acne (17/23, 73.9%), obesity/weight loss/slimming (17/23, 73.9%) and psoriasis (17/23, 73.9%). Claimed conditions/uses included some serious medical conditions (e.g. diabetes, cancer and hypertension) and those focusing on vulnerable groups (e.g. children's diseases and pregnancy treatments). TCM shops in London, UK, typically displayed names of a wide range of medical conditions/uses for TCMs using readily understandable medical terms, implying TCM can be used to prevent or treat these conditions. However, many of these advertisements did not comply with UK regulations on medical claims for herbal medicines. Future studies should explore how these advertisements influence consumers' decisions to access TCM in the UK, practices of TCM shop staff towards the supply of TCMs in the UK, and what are the health implications at the individual and population levels.

Medical pluralism of the Chinese in London: an exploratory study.

PubMed

Rochelle, Tina L; Marks, David F

2010-11-01

This study was designed to examine the extent of medical pluralism among the Chinese in London. Members of the London Chinese community were recruited through Chinese organizations in London and participated in six focus groups. A total of 48 Chinese men and women aged 24-74 years were asked to talk about their health behaviour and health utilization patterns. Transcripts of the focus group discussions underwent thematic analysis to explore and describe the utilization of traditional Chinese medicine (TCM) and Western medicine (WM) of informants and factors that impacted on utilization. Findings focus on participants' evaluation of TCM and WM as two systems of health provision, how informants used these two health systems, and the reasons associated with use of these two systems. Utilization of TCM and WM varied. Concurrent use of TCM and WM was common. The National Health Service was generally perceived as difficult to use, with concerns over the language barrier, and communicating with and being able to trust health providers. The UK TCM trade was perceived as being aimed at the non-Chinese market and there were issues of trust related to the regulation of UK TCM. Although none of these issues are unique to the Chinese in the UK, previous experience with different approaches to health care, particularly TCM, may make the experience of such barriers more extreme.

Coronary artery disease (CAD), a common disease with high incidence and mortality rate, has seriously threatened the health and life of the public. Traditional Chinese medicine (TCM) has an important role in the prevention and treatment of this disease. Through clinical epidemiological survey, a deeper understanding of TCM etiology and syndrome characteristics in CAD would further improve clinical efficacy in the treatment of this disease. The preliminary clinical questionnaire for TCM etiology and syndrome differentiation in CAD was designed after literature reviews and analysis. Through a series of clinical pre-surveys, expert consultation and demonstration, the formal TCM clinical epidemiology questionnaire on the etiology and syndrome differentiation in CAD was finalized, after which, the study protocol, inclusive and exclusive criteria and related quality control measures were prepared. The multiregional clinical epidemiological survey with more than 5000 participants with CAD will be carried out in 41 TCM hospitals of China for investigating the TCM etiology and syndrome differentiation of CAD. Multiregion large sample size clinical epidemiology survey on TCM etiology and syndrome differentiation in CAD will provide further evidence in preventing CAD and improving the standardization process of syndrome research. This study protocol was registered at the Chinese Clinical Trial Registry on November 27, 2011 in both Chinese and English editions and the registration number is ChiCTR-ECS-11001728.

Traditional Chinese medicine (TCM) has a long history and been widely used in prevention and treatment of epilepsy in China. This paper is intended to review the advances in the active anticonvulsant compounds isolated from herbs in the prescription of TCM in the treatment of epilepsy. These compounds were introduced with the details including classification, CAS number specific structure and druggability data. Meanwhile, much of the research in these compounds in the last two decades has shown that they exhibited favorable pharmacological properties in treatment of epilepsy both in in vivo and in vitro models. In addition, in this present review, the evaluation of the effects of the anticonvulsant classical TCM prescriptions is discussed. According to these rewarding pharmacological effects and chemical substances, the prescription of TCM herbs could be an effective therapeutic strategy for epilepsy patients, and also could be a promising source for the development of new drugs.

Traditional Chinese Medicine (TCM) has been used to treat diseases in China for thousands of years. TCM compositions are complex, using as their various sources plants, animals, fungi, and minerals. Polysaccharides are one of the active and important ingredients of TCMs. Polysaccharides from TCMs exhibit a wide range of biological activities in terms of immunity- modifying, antiviral, anti-inflammatory, anti-oxidative, and anti-tumor properties. With their widespread biological activities, polysaccharides consistently attract scientist's interests, and the studies often concentrate on the extraction, purification, and biological activity of TCM polysaccharides. Currently, numerous studies have shown that the modification of polysaccharides can heighten or change the biological activities, which is a new angle of polysaccharide research. This review highlights the current knowledge of TCM polysaccharides, including their extraction, purification, modification, and biological activity, which will hopefully provide profound insights facilitating further research and development.

Graves' disease is an autoimmune disease that can affect a few patients with hyperthyroidism. In this case report, we demonstrated that Traditional Chinese Medicine (TCM) was effective for the patient with hyperthyroidism induced by Graves' disease. The patient also remained in the euthyroid state for several years after the treatment. SUBJECT AND SETTING: A 33-year-old woman had palpitations, fatigability, and weight loss and was diagnosed as having Graves' disease. Urticaria and itching skin appeared after she took an antithyroid drug. Therefore, she sought treatment with TCM. After regular therapy with Jia Wei Xiao Yao San in addition to Xia Ku Cao, Bei Mu, and oyster shell, her symptoms subsided and the thyroid function level returned to normal range with 3 years' treatment. She still remained in the euthyroid state for 3 years after discontinuing the TCM treatment up to the present. Neither complications nor side-effects were noted during the TCM treatment. This case demonstrates that TCM is an effective and alternative option for hyperthyroidism induced by Graves' disease, especially for patients who have an allergic reaction caused by thioamides.

A large body of evidence has shown that inflammation and cancer are strongly related. Thus anti-inflammatory agents have been investigated for cancer prevention and treatment in preclinical and clinical studies, including the nonsteroidal anti-inflammatory drugs (NSAIDs) and traditional Chinese medicine (TCM). In TCM, there exist a wide range of biologically active substances, such as saponins, flavonoids, alkaloids, polysaccharides, polyphenols, phenylpropanoids, and quinones. Many of these active ingredients have been reported to inhibit inflammation, activate inflammatory immune response, and/or inhibit cancer cell proliferation and tumor growth. Given the potential role of inflammation in cancer initiation and progression, the inflammatory tumor microenvironment, the cross-talks between inflammatory and cancer cells, and multitargeting activities of some TCM compounds, we summarize the current knowledge on the anti-inflammatory and anti-cancer properties of ingredients of TCM together with their underlying mechanisms in an integrated way. We hope to provide a reliable basis and useful information for the development of new treatment strategies of inflammation and cancer comprehensively using TCM and their active ingredients.

Cardiovascular diseases (CVDs) have been recognized as first killer of human health. The underlying mechanisms of CVDs are extremely complicated and not fully revealed, leading to a challenge for CVDs treatment in modern medicine. Traditional Chinese medicine (TCM) characterized by multiple compounds and targets has shown its marked effects on CVDs therapy. However, system-level understanding of the molecular mechanisms is still ambiguous. In this study, a system pharmacology approach was developed to reveal the underlying molecular mechanisms of a clinically effective herb formula (Wen-Dan Decoction) in treating CVDs. 127 potential active compounds and their corresponding 283 direct targets were identified in Wen-Dan Decoction. The networks among active compounds, targets, and diseases were built to reveal the pharmacological mechanisms of Wen-Dan Decoction. A "CVDs pathway" consisted of several regulatory modules participating in therapeutic effects of Wen-Dan Decoction in CVDs. All the data demonstrates that Wen-Dan Decoction has multiscale beneficial activity in CVDs treatment, which provides a new way for uncovering the molecular mechanisms and new evidence for clinical application of Wen-Dan Decoction in cardiovascular disease.

2004-03-01

Traditional Chinese medicines (TCM) are popular in the United States and Asian and non-Asian consumers are using the product for disease treatment and health prevention. As more people are using TCM products, there are increased reports on adverse reactions. This review will focus on adverse reactions due to TCM as reported in the literature. The review is based on MedLine search of literatures using keywords including: herbs, herbal, traditional Chinese medicines with toxicity, adverse effects, death, drug interaction and pharmacokinetic. In addition, specific searches were performed using the above keywords with the common name and the scientific name of the plant product. The causes of adverse reactions associated with TCM are diverse. They include variability in active/toxic ingredients due to growing conditions, use of inherent toxic herbs causing toxicity, overdose of herbs, drug-herb interactions especially with pharmaceuticals that have narrow therapeutic index, coexisting diseases, and idiosyncratic reactions like allergy, hepatitis and anaphylaxis. Other adverse reactions can be due to manufacturing and quality problems causing adulteration, misidentification, substitution of one herb with another, variability in the amount of active ingredients, use of pharmaceuticals without identifying on the labels, improper processing and preparation, and contamination. To minimize the adverse reactions from TCM and protect the public, there must be adequate laws and regulations to ensure that products are manufactured with the highest standards. Manufacturers should be licensed by regulatory agency and manufactured under good manufacturing practice. TCM products must be evaluated for their safety before marketing. Proper labeling and good surveillance systems shall ensure the protection of the consumers.

The most important influence of art of changes on traditional Chinese medicine (TCM) was reflected in the formation of the basic theory of TCM. Some innovations were achieved by using the theory of art of changes to research medicine in later ages. However, the specific therapies and the prognostication of diseases inferred by using the art of mathematics were mostly unreliable. Though the researches on the art of changes were helpful to the exploration of the cause and effect of TMC, yet, its practical significance should be evaluated properly.

Erectile dysfunction treatment and traditional medicine—can East and West medicine coexist?

Erectile dysfunction (ED) is a common sexual problem affecting many men irrespective of cultures, beliefs and nationalities. While medical therapy for ED has been revolutionized by the advent of oral phosphodiesterase type 5 inhibitors and intracavernosal injection of vasoactive agents, recent technological advances such stem cell therapy, low intensity shock wave and newer generation of penile prosthesis implant offer hope to men who do not respond to conventional medical therapy. In contrast, traditional and complementary medicine (TCM) focuses on the restoration and better overall bodily regulation with the use of various herbal and animal products as well as exercises to invigorate qi (energy) in vital organs. Western medicine involves an analysis of ED symptom and underlying causes that contribute to ED, while TCM emphases the concept of holism and harmonization of body organs to achieve natural sexual life. The following article reviews our current understanding regarding the philosophical approach, and evaluates the evidence surrounding various ED therapies between mainstream Western Medicine and TCM.

Abstract Background This study searches the National Health Insurance Research Database (NHIRD) used in a previous project, aiming for reconstructing possible cerebrovascular disease-related groups (DRG),and estimating the costs between cerebrovascular disease and related diseases. Methods and Materials We conducted a nationwide retrospective cohort study in stroke inpatients, we examined the overall costs in 3 municipalities in Taiwan, by evaluating the possible costs of the expecting diagnosis related group (DRG) by using the international classification of diseases version-9 (ICD-9) system, and the overall analysis of the re-admission population that received traditional Chinese medicine (TCM) treatment and those who did not. Results The trend demonstrated that the non-participant costs were consistent with the ICD-9 categories (430 to 437) because similarities existed between years 2006 to 2007. Among the TCM patients, a wide variation and additional costs were found compared to non-TCM patients during these 2 years. The average re-admission duration was significantly shorter for TCM patients, especially those initially diagnosed with ICD 434 during the first admission. In addition, TCM patients demonstrated more severe general symptoms, which incurred high conventional treatment costs, and could result in re-admission for numerous reasons. However, in Disease 7 of ICD-9 category, representing the circulatory system was most prevalent in non-TCM inpatients, which was the leading cause of re-admission. Conclusion We concluded that favorable circulatory system outcomes were in adjuvant TCM treatment inpatients, there were less re-admission for circulatory system events and a two-third reduction of re-admission within ICD-9 code 430 to 437, compared to non-TCM ones. However, there were shorter re-admission duration other than circulatory system events by means of unfavorable baseline condition. PMID:24475108

Drug-drug interactions have long been an active research area in clinical medicine. In Taiwan, however, the widespread use of traditional Chinese medicines (TCM) presents additional complexity to the topic. Therefore, it is important to see the interaction between traditional Chinese and western medicine. (1) To create a comprehensive database of multi-herb/western drug interactions indexed according to the ways in which physicians actually practice and (2) to measure this database's impact on the detection of adverse effects between traditional Chinese medicine compounds and western medicines. First, a multi-herb/western medicine drug interactions database was created by separating each TCM compound into its constituent herbs. Each individual herb was then checked against an existing single-herb/western drug interactions database. The data source comes from the National Health Insurance research database, which spans the years 1998-2011. This study estimated the interaction prevalence rate and further separated the rates according to patient characteristics, distribution by county, and hospital accreditation levels. Finally, this new database was integrated into a computer order entry module of the electronic medical records system of a regional teaching hospital. The effects it had were measured for two months. The most commonly interacting Chinese herbs were Ephedrae Herba and Angelicae Sinensis Radix/Angelicae Dahuricae Radix. Ephedrae Herba contains active ingredients similar to in ephedrine. 15 kinds of traditional Chinese medicine compounds contain Ephedrae Herba. Angelicae Sinensis Radix and Angelicae Dahuricae Radix contain ingredients similar to coumarin, a blood thinner. 9 kinds of traditional Chinese medicine compounds contained Angelicae Sinensis Radix/Angelicae Dahuricae Radix. In the period from 1998 to 2011, the prevalence of herb-drug interactions related to Ephedrae Herba was 0.18%. The most commonly prescribed traditional Chinese compounds were MA SHING GAN SHYR TANG (23.1%), followed by SHEAU CHING LONG TANG (15.5%) and DINQ CHUAN TANG (13.2%). The prevalence of herb-drug interactions related to Angelicae Sinensis Radix, Angelicae Dahuricae Radix was 4.59%. The most common traditional Chinese compound formula were TSANG EEL SAAN (32%), followed by HUOH SHIANG JENQ CHIH SAAN (31.4%) and SHY WUH TANG (10.7%). Once the multi-herb drug interaction database was deployed in a hospital system, there were 480 prescriptions that indicated a TCM-western drug interaction. Physicians were alerted 24 times during two months. These alerts resulted in a prescription change four times (16.7%). Due to the unique cultural factors that have resulted in widespread acceptance of both western and traditional Chinese medicine, Taiwan stands well positioned to report on the prevalence of interactions between western drugs and traditional Chinese medicine and devise ways to reduce their incidence. This study built a multi-herb/western drug interactions database, embedded inside a hospital clinical information system, and then examined the effects that drug interaction alerts had on clinician prescribing behaviour. The results demonstrated that western drug/traditional Chinese medicine interactions are prevalent and that western-trained physicians tend to change their prescribing behaviour more than traditional Chinese medicine physicians in their response to medication interaction alerts.

Traditional Chinese Medicine (TCM) is one of the most popular complementary and alternative medicine modalities worldwide. In Chinese and East Asian societies, TCM plays an active role in the modern health care system and is even covered by the National Health Insurance Program of Taiwan. Liver cancer is the second most common cancer in Taiwan. This study aimed to analyze the TCM utilization patterns of patients with liver cancer from 1996-2007 using a population-based random sample of one million insured patients. A cross-sectional study was conducted using registration and claim data sets from 1996 to 2007 obtained from the Longitudinal Health Insurance Database 2005 (LHID2005). The outpatient datasets contained the encounter form-based dates of visit, three items from the International Classification of Diseases (Ninth Revision, Clinical Modification codes), the primary procedure (e.g., drug or diagnostic procedure), type of copayment, billed amount, and paid amount. Only ambulatory care was analyzed. A total of 6358 liver cancer patients utilized ambulatory care during the study period. Among them, 1240 (19.50%) availed of TCM outpatient services. The prevalence of TCM use fluctuated during the study period, with a peak of 25.11% in 2001. After multivariable adjustment, the likelihood of TCM users was lower in participants aged 70 years and older (odds ratio, OR = 0.79, 95% confidence interval, CI: 0.64-0.97), males (OR = 0.60, 95% CI: 0.52-0.68), residents of Taipei (OR = 0.75, 95% CI: 0.58-0.96) as well as farmers and fishermen (OR = 0.71, 95% CI: 0.54-0.94), but was higher in residents of central Taiwan (OR = 1.99, 95% CI: 1.56-2.54. Most biomedicine and TCM outpatient services were provided by private clinics, followed by private hospitals. The two most frequently recorded coexisting diseases for both biomedicine and TCM outpatient visits specifically for liver cancer were (1) chronic liver disease and cirrhosis, and (2) malignant neoplasm of the liver and hepatic bile duct. The mean fee per visit for biomedicine was much higher than that for TCM, and the average expenditure was NT$429.73 (US$13.25) per biomedicine visit and NT$301.93 (US$9.32) per TCM visit (US$1 = NT$32.4 in 2007). For outpatient visits specifically for liver cancer, the mean fee per visit for biomedicine was much higher than that for TCM. The average cost per visit was NT$1457.31 (US$44.98) for biomedicine and NT$1080.76 (US$33.36) for TCM. TCM was widely used by the patients with liver cancer, and the prevalence of TCM use remained stably high during the study period. The costs of insurance covering TCM were consistently lower than those covering biomedicine in patients with liver cancer. The findings of this study should be useful for health policy makers as well as researchers considering the integration of TCM and biomedicine.

Background. The development of an evidence-based approach to traditional Chinese medicine (TCM), which depends on the generation of good quality evidence, requires an adequate workforce. However, the research capacity of TCM investigators is not known. Study Design. This cross-sectional study was conducted to describe the research capacity of TCM clinical investigators in China. Participants. A total of 584 participants from TCM hospitals and research centers were included. They were asked about the academic and research characteristics, needs for research capacity building, and barriers to clinical research. Results. The majority (80.82%) were qualified to at least a Master's degree, whilst a smaller proportion (40.24%) held a senior professional title. We found that academic outputs were low with the majority (62.16%) authoring less than five publications in total. The most pressing needs for building research capacity identified were training in research methodology (97.43%) and identification of research questions (86.81%), whilst the highest ranking barriers to conducting research were limited motivation, funding (40.72%), and time (37.15%). Conclusion. The methodology training, along with investment in the research workforce, needs to be urgently addressed to improve investigators' research capacity and the development of an evidence-based approach of TCM.

Bai-Hu-Tang (BHT), a classic traditional Chinese medicine (TCM) formula used for clearing heat and promoting body fluid, consists of four traditional Chinese medicines, i.e., Gypsum Fibrosum (Shigao), Anemarrhenae Rhizoma (Zhimu), Glycyrrhizae Radix et Rhizoma Praeparata cum Melle (Zhigancao), and nonglutinous rice (Jingmi). The chemical composition of BHT still remains largely elusive thus far. To qualitatively and quantitatively characterize secondary metabolites and carbohydrates in BHT, here a combination of analytical approaches using ultraperformance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry and ultraperformance liquid chromatography coupled with photodiode array detector was developed and validated. A total of 42 secondary metabolites in BHT were tentatively or definitely identified, of which 10 major chemicals were quantified by the extracting ion mode of quadrupole time-of-flight mass spectrometry. Meanwhile, polysaccharides, oligosaccharides, and monosaccharides in BHT were also characterized via sample pretreatment followed by sugar composition analysis. The quantitative results indicated that the determined chemicals accounted for 35.76% of the total extract of BHT, which demonstrated that the study could be instrumental in chemical dissection and quality control of BHT. The research deliverables not only laid the root for further chemical and biological evaluation of BHT, but also provided a comprehensive analytical strategy for chemical characterization of secondary metabolites and carbohydrates in traditional Chinese medicine formulas.

Extracting meaningful information and knowledge from free text is the subject of considerable research interest in the machine learning and data mining fields. Text data mining (or text mining) has become one of the most active research sub-fields in data mining. Significant developments in the area of biomedical text mining during the past years have demonstrated its great promise for supporting scientists in developing novel hypotheses and new knowledge from the biomedical literature. Traditional Chinese medicine (TCM) provides a distinct methodology with which to view human life. It is one of the most complete and distinguished traditional medicines with a history of several thousand years of studying and practicing the diagnosis and treatment of human disease. It has been shown that the TCM knowledge obtained from clinical practice has become a significant complementary source of information for modern biomedical sciences. TCM literature obtained from the historical period and from modern clinical studies has recently been transformed into digital data in the form of relational databases or text documents, which provide an effective platform for information sharing and retrieval. This motivates and facilitates research and development into knowledge discovery approaches and to modernize TCM. In order to contribute to this still growing field, this paper presents (1) a comparative introduction to TCM and modern biomedicine, (2) a survey of the related information sources of TCM, (3) a review and discussion of the state of the art and the development of text mining techniques with applications to TCM, (4) a discussion of the research issues around TCM text mining and its future directions.

Currently, the chemical fingerprint comparison and analysis is mainly based on professional equipment and software, it's expensive and inconvenient. This study aims to integrate QR (Quick Response) code with quality data and mobile intelligent technology to develop a convenient query terminal for tracing quality in the whole industrial chain of TCM (traditional Chinese medicine). Three herbal medicines were randomly selected and their chemical two-dimensional barcode (2D) barcodes fingerprints were constructed. Smartphone application (APP) based on Android system was developed to read initial data of 2D chemical barcodes, and compared multiple fingerprints from different batches of same species or different species. It was demonstrated that there were no significant differences between original and scanned TCM chemical fingerprints. Meanwhile, different TCM chemical fingerprint QR codes could be rendered in the same coordinate and showed the differences very intuitively. To be able to distinguish the variations of chemical fingerprint more directly, linear interpolation angle cosine similarity algorithm (LIACSA) was proposed to get similarity ratio. This study showed that QR codes can be used as an effective information carrier to transfer quality data. Smartphone application can rapidly read quality information in QR codes and convert data into TCM chemical fingerprints.

2010-01-01

More and more patients have been diagnosed as having chronic fatigue syndrome (CFS) in recent years. Western drug use for this syndrome is often associated with many side-effects and little clinical benefit. As an alternative medicine, traditional Chinese medicine (TCM) has provided some evidences based upon ancient texts and recent studies, not only to offer clinical benefit but also offer insights into their mechanisms of action. It has perceived advantages such as being natural, effective and safe to ameliorate symptoms of CFS such as fatigue, disordered sleep, cognitive handicaps and other complex complaints, although there are some limitations regarding the diagnostic standards and methodology in related clinical or experimental studies. Modern mechanisms of TCM on CFS mainly focus on adjusting immune dysfunction, regulating abnormal activity in the hypothalamic-pituitary-adrenal (HPA) axis and serving as an antioxidant. It is vitally important for the further development to establish standards for ‘zheng’ of CFS, i.e. the different types of CFS pathogenesis in TCM, to perform randomized and controlled trials of TCM on CFS and to make full use of the latest biological, biochemical, molecular and immunological approaches in the experimental design.

Small- and medium-sized enterprises (SMEs) have played key roles in the economic growth and technical innovation of traditional and complementary and alternative medicine (T&CM). Research and development (R&D) are critical activities for industrial progress. This study aimed to characterize the current status of SME R&D activities and to explore manufacturers' perceptions of R&D expansion. Records of the distribution of T&CM SMEs and R&D resources detailed in the 2014 Statistics of Korea T&CM Industries survey, a previously conducted survey on the industrial status of the T&CM field, were reviewed. Data on the perceptions of R&D activities were investigated through a company-based survey covering 285 T&CM-manufacturing SMEs. Greater than 99% of the 13,636 T&CM manufacturers at the time of the study were SMEs employing less than 50 workers. Natural cosmetics manufacturing SMEs (NC SMEs) had the highest R&D expenditures. NC SMEs rely heavily on internal R&D operations, which may contribute to their strong need for R&D collaboration with public research institutions and expanded T&CM-promoted R&D programs. "Digestive system disorders" are the main target diseases for current herbal and dietary supplement manufacturing SMEs and herbal medicine manufacturing SMEs. These SMEs tend to view their own product-related business as a priority for future R&D investment. This study represents the first attempt to assess SME perceptions of R&D activities. The findings herein can inform the design of sustainable programs that support R&D by reducing the gaps between the perspectives of T&CM product makers and policymakers.

Primary liver cancer (PLC) is one of the most common malignant tumors because of its high incidence and high mortality. Traditional Chinese medicine (TCM) plays an active role in the treatment of PLC. As the most important part in the TCM system, syndrome differentiation based on the clinical manifestations from traditional four diagnostic methods has met great challenges and questions with the lack of statistical validation support. In this study, we provided evidences for TCM syndrome differentiation of PLC using the method of analysis of latent structural model from clinic data, thus providing basis for establishing TCM syndrome criteria. And also we obtain the common syndromes of PLC as well as their typical clinical manifestations, respectively.

The theory of traditional Chinese medicine (TCM) constitution involves genetic characteristics, psychological factors, organ functions, and many other aspects. Studies have shown that TCM constitution is associated with HLA polymorphisms and has a genetic basis. A large number of Chinese studies have suggested that the clinical evolution of breast cancer may differ among patients with different TCM constitutions. In addition, patients with breast cancer and different TCM constitutions may have different degrees of myelosuppression after chemotherapy. Some studies have revealed that some constitutions may become predictive factors for death and morbidity of some diseases. The study was to investigate the risk factors among TCM constitutions for chemotherapy-induced nausea and vomiting (CINV) in patients with primary breast cancer undergoing chemotherapy. From September 2008 to January 2014, 612 patients who underwent surgery and chemotherapy for breast cancer in three hospitals in Xi'an, Shanxi province, underwent TCM constitution assessment using the Nine Basic Constitutions in Chinese Medicine Questionnaire before chemotherapy. CINV was monitored during treatments. Patients were asked to complete the Functional Living Index-Emesis (FLIE) questionnaire. The most severe CINV grade during chemotherapy was recorded according to the WHO standard. The relationships between TCM constitutions, CINV, and clinical and pathological characteristics of the cancers were assessed. There were no differences in the incidence of CINV among breast cancer patients receiving different chemotherapy regimens, and among patients with different TCM constitutions. The wetness-heat score was an independent risk factor for severe CINV (grade III-IV) (OR = 1.012, 95 % CI: 1.007-1.021, P < 0.001). In-depth analyses of the wetness-heat constitution showed that bitter taste/smelly mouth was an independent risk factor for severe CINV (OR = 1.209, 95 % CI: 1.035-1.412, P = 0.017), as well as progesterone receptor-positive cancer (OR = 1.429, 95 % CI: 1.030-1.981, P = 0.032). Vomiting history was a protective factor against CINV (OR = 0.548, 95 % CI: 0.353-0.849, P = 0.007). Risk of grade III-IV nausea and vomiting was higher in breast cancer patients with TCM constitution of wetness-heat, especially bitter taste or smelly mouth.

To develop a policy, practice, education and research agenda for evidence-based practice (EBP) in traditional and complementary medicine (T&CM). The study was a secondary analysis of qualitative data, using the method of roundtable discussion. The sample comprised seventeen experts in EBP and T&CM. The discussion was audio-recorded, and the transcript analysed using thematic analysis. Four central themes emerged from the data; understanding evidence and EBP, drivers of change, interpersonal interaction, and moving forward. Captured within these themes were fifteen sub-themes. These themes/sub-themes translated into three broad calls to action: (1) defining terminology, (2) defining the EBP approach, and (3) fostering social movement. These calls to action formed the framework of the agenda. This analysis presents a potential framework for an agenda to improve EBP implementation in T&CM. The fundamental elements of this action plan seek clarification, leadership and unification on the issue of EBP in T&CM. Copyright © 2018 Elsevier Ltd. All rights reserved.

Human histone deacetylase 2 (HDAC2) has been identified as being associated with Alzheimer's disease (AD), a neuropathic degenerative disease. In this study, we screen the world's largest Traditional Chinese Medicine (TCM) database for natural compounds that may be useful as lead compounds in the search for inhibitors of HDAC2 function. The technique of molecular docking was employed to select the ten top TCM candidates. We used three prediction models, multiple linear regression (MLR), support vector machine (SVM), and the Bayes network toolbox (BNT), to predict the bioactivity of the TCM candidates. Molecular dynamics simulation provides the protein-ligand interactions of compounds. The bioactivity predictions of pIC50 values suggest that the TCM candidatesm, (−)-Bontl ferulate, monomethylcurcumin, and ningposides C, have a greater effect on HDAC2 inhibition. The structure variation caused by the hydrogen bonds and hydrophobic interactions between protein-ligand interactions indicates that these compounds have an inhibitory effect on the protein.

Sheng-ji Hua-yu(SJHY) formula is one of the most useful Traditional Chinese medicine (TCM) in the treatment of the delayed diabetic wound. However, elucidating the related molecular biological mechanism of how the SJHY Formula affects excessive inflammation in the process of re-epithelialization of diabetic wound healing is a task urgently needed to be fulfilled. The objectives of this study is to evaluate the effect of antagonisic expression of pro-/anti-inflammatory factors on transforming growth factor-β(TGF-β) superfamily (activin and follistatin) in the process of re-epithelialization of diabetic wound healing in vivo, and to characterize the involvement of the activin/follistatin protein expression regulation, phospho-Smad (pSmad2), and Nuclear factor kappa B p50 (NF-kB) p50 in the diabetic wound healing effects of SJHY formula. SJHY Formula was prepared by pharmaceutical preparation room of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine. Diabetic wound healing activity was evaluated by circular excision wound models. Wound healing activity was examined by macroscopic evaluation. Activin/follistatin expression regulation, protein expression of pSmad2 and NF-kB p50 in skin tissue of wounds were analyzed by Real Time PCR, Western blot, immunohistochemistry and hematoxylin and eosin (H&E) staining. Macroscopic evaluation analysis showed that wound healing of diabetic mice was delayed, and SJHY Formula accelerated wound healing time of diabetic mice. Real Time PCR analysis showed higher mRNA expression of activin/follistatin in diabetic delayed wound versus the wound in normal mice. Western Blot immunoassay analysis showed reduction of activin/follistatin proteins levels by SJHY Formula treatment 15 days after injury. Immunohistochemistry investigated the reduction of pSmad2 and NF-kB p50 nuclear staining in the epidermis of diabetic SJHY versus diabetic control mice on day 15 after wounding. H&E staining revealed that SJHY Formula accelerated re-epithelialization of diabetic wound healing. The present study found that diabetic delayed wound healing time is closely related to the high expression level of activin/follistatin, which leads to excessive inflammation in the process of re-epithelization. SJHY Formula accelerates re-epithelialization and healing time of diabetic wounds through decreasing the high expression of activin/follistatin.

Chloride intracellular channel 1 (CLIC1) is involved in the development of most aggressive human tumors, including gastric, colon, lung, liver, and glioblastoma cancers. It has become an attractive new therapeutic target for several types of cancer. In this work, we aim to identify natural products as potent CLIC1 inhibitors from Traditional Chinese Medicine (TCM) database using structure-based virtual screening and molecular dynamics (MD) simulation. First, structure-based docking was employed to screen the refined TCM database and the top 500 TCM compounds were obtained and reranked by X-Score. Then, 30 potent hits were achieved from the top 500 TCM compounds using cluster and ligand-protein interaction analysis. Finally, MD simulation was employed to validate the stability of interactions between each hit and CLIC1 protein from docking simulation, and Molecular Mechanics/Generalized Born Surface Area (MM-GBSA) analysis was used to refine the virtual hits. Six TCM compounds with top MM-GBSA scores and ideal-binding models were confirmed as the final hits. Our study provides information about the interaction between TCM compounds and CLIC1 protein, which may be helpful for further experimental investigations. In addition, the top 6 natural products structural scaffolds could serve as building blocks in designing drug-like molecules for CLIC1 inhibition. PMID:29147652

It has been uncovered that chemical dyes are illegally used in traditional Chinese medicines to brighten color and cover up inferiority, which threaten the safety of patients. In the present study, an HPTLC-MS method was developed for the effective screening of 11 chemical dyes (Sudan I, II, III, and IV; 808 Scarlet; Sudan Red 7B; malachite green; Basic Orange 2; auramine; Orange II; and erythrosine) in traditional Chinese medicine (TCM) raw materials and Chinese patent medicines. Firstly, unwashed HPTLC plates were chosen by comparing the background signals of the TLC plates used directly and prewashed with analytical grade and HPLC grade solvents. Twice developments were conducted to isolate chemical dyes of different polarity. Possible adulterants were preliminarily identified by comparing Rf values and in situ UV-Vis spectra with those of the references. Further confirmation was conducted by tandem MS analysis via an elution head-based TLC-MS interface. Sudan I and IV, 808 Scarlet, and Orange II were successfully detected in eight batches of TCM. The proposed method could be applied as a reliable technology for the screening of chemical dyes in TCM.

Background. Chinese herbal products (CHPs) given as a therapy for symptom relief have gained widespread popularity among women with breast cancer. The aim of this study was to analyze the utilization of CHP among women with breast cancer in Taiwan. Methods. The usage, frequency of services, and CHP prescribed for breast cancer among women with breast cancer were evaluated, recruited from a randomly sampled cohort of 1,000,000 beneficiaries from the National Health Insurance Research Database. The logistic regression method was employed to estimate the odds ratios (ORs) for utilization of CHP. Results. 81.5 percent (N = 2, 236) of women with breast cancer utilized traditional Chinese medicine (TCM) and 18% of them sought TCM with the intent of treating their breast cancer. Jia-wei-xiao-yao-san (Augmented Rambling Powder) was the most frequently prescribed formula for treating breast cancer. Among the top 10 most frequently prescribed CHP for treating breast cancer, seven contained dang qui (Angelica sinensis-radix) and six contained ren shen (Panax ginseng-radix), which are reported to have potential beneficial synergistic effects on breast cancer cells. Conclusion. CHP containing dang qui (Angelica sinensis-radix) or ren shen (Panax ginseng-radix) are the most frequently prescribed for breast cancer and their effects should be taken into account by healthcare providers.

Yuanhu Zhitong prescription (YZP) is a typical and relatively simple traditional Chinese medicine (TCM), widely used in the clinical treatment of headache, gastralgia, and dysmenorrhea. However, the underlying molecular mechanism of action of YZP is not clear. In this study, based on the previous chemical and metabolite analysis, a complex approach including the prediction of the structure of metabolite, high-throughput in silico screening, and network reconstruction and analysis was developed to obtain a computational drug-target network for YZP. This was followed by a functional and pathway analysis by ClueGO to determine some of the pharmacologic activities. Further, two new pharmacologic actions, antidepressant and antianxiety, of YZP were validated by animal experiments using zebrafish and mice models. The forced swimming test and the tail suspension test demonstrated that YZP at the doses of 4 mg/kg and 8 mg/kg had better antidepressive activity when compared with the control group. The anxiolytic activity experiment showed that YZP at the doses of 100 mg/L, 150 mg/L, and 200 mg/L had significant decrease in diving compared to controls. These results not only shed light on the better understanding of the molecular mechanisms of YZP for curing diseases, but also provide some evidence for exploring the classic TCM formulas for new clinical application.

The beginning of TCM acupuncture in New Zealand dates back to the middle of 19th century. After self-improvement for more than 100 years, TCM acupuncture has gained a considerable development. From the perspective of history and current situation, the development of acupuncture in New Zealand was elaborated in this article; in addition, the sustainable development of acupuncture was discussed from the perspective of education and training. In New Zealand, the TCM acupuncture and dry needling have played a dominant role in acupuncture treatments, which are practiced by TCM practitioners and physical therapists. The TCM acupuncture is widely applied in department of internal medicine, surgery, gynecology, and pediatrics, etc., while the dry needling is li-mited for traumatology and pain disorder. Therefore, including TCM acupuncture into the public medical and educational system in New Zealand should be an essential policy of Ministry of Health to provide welfare for the people.

Holistic medicine is an interdisciplinary field of study that integrates all types of biological information (protein, small molecules, tissues, organs, external environmental signals, etc.) to lead to predictive and actionable models for health care and disease treatment. Despite the global and integrative character of this discipline, a comprehensive picture of holistic medicine for the treatment of complex diseases is still lacking. In this study, we develop a novel systems pharmacology approach to dissect holistic medicine in treating cardiocerebrovascular diseases (CCDs) by TCM (traditional Chinese medicine). Firstly, by applying the TCM active ingredients screened out by a systems-ADME process, we explored and experimentalized the signed drug-target interactions for revealing the pharmacological actions of drugs at a molecule level. Then, at a/an tissue/organ level, the drug therapeutic mechanisms were further investigated by a target-organ location method. Finally, a translational integrating pathway approach was applied to extract the diseases-therapeutic modules for understanding the complex disease and its therapy at systems level. For the first time, the feature of the drug-target-pathway-organ-cooperations for treatment of multiple organ diseases in holistic medicine was revealed, facilitating the development of novel treatment paradigm for complex diseases in the future.

The objective of this study was to determine the efficacy of individually designed herbal formulas according to the rules of Traditional Chinese Medicine (TCM) in patients with osteoarthritis of the hip and knee. This was a randomized, controlled, double-blind study with two parallel groups. This study was conducted at the University-centre in Gars am Kamp/Austria and was organized by the Institute of TCM and Complementary Medicine of the Danube University Krems /Austria. The study comprised female and male patients with osteoarthritis of hip or knee aged between 45 and 75 years. Patients were randomized into a treatment with individualized, water-based herbal decoctions prepared in a standardized cooking process (Verum group) or to a treatment with nonspecific presumably ineffective, water-based herbal decoctions (Control group). The primary outcome was the comparison of change between the intervention groups in the Western Ontario and McMaster Universities lower limb global index questionnaire (WOMAC global index) between baseline and week 20. Secondary outcomes included subscales of WOMAC for pain (A), stiffness (B), and functional impairment (C) and general quality of life in the form of the SF-36 questionnaire. Altogether, 102 patients were randomized in this trial. The demographic and medical baseline characteristics were comparable in the 2 groups. The change of the WOMAC global index and all three subscales was significant in both groups between week 20 and baseline (verum group, global WOMAC: at baseline 47 [SD ± 11.8] and at week 20: 24 (SD ± 18.3); change of mean 23; p > 0.001; control group; global WOMAC: at baseline: 48 (SD ± 14.7) and at week 20: 25 (SD ± 18.3); change of mean 23; p > 0.001). However, there was no significant difference (p = 0.783) between the treatment groups. There were significant changes in the subscales "physical functioning," "bodily pain," "vitality," "social-functioning," and "role-physical" of the SF-36 in both study groups between 20 weeks and baseline, but again no significant difference between the groups. There were no drug-related serious adverse events. While the individual prescription consisting of medicinal herbs according to TCM diagnosis investigated in this trial tend to improve the osteoarthritis, the same effect was also achieved with the nonspecific prescription.

AIM To analyze liver tests before and following treatment with herbal Traditional Chinese Medicine (TCM) in order to evaluate the frequency of newly detected liver injury. METHODS Patients with normal values of alanine aminotransferase (ALT) as a diagnostic marker for ruling out pre-existing liver disease were enrolled in a prospective study of a safety program carried out at the First German Hospital of TCM from 1994 to 2015. All patients received herbal products, and their ALT values were reassessed 1-3 d prior to discharge. To verify or exclude causality for suspected TCM herbs, the Roussel Uclaf Causality Assessment Method (RUCAM) was used. RESULTS This report presents for the first time liver injury data derived from a prospective, hospital-based and large-scale study of 21470 patients who had no liver disease prior to treatment with herbal TCM. Among these, ALT ranged from 1 × to < 5 × upper limit normal (ULN) in 844 patients (3.93%) and suggested mild or moderate liver adaptive abnormalities. However, 26 patients (0.12%) experienced higher ALT values of ≥ 5 × ULN (300.0 ± 172.9 U/L, mean ± SD). Causality for TCM herbs was RUCAM-based probable in 8/26 patients, possible in 16/26, and excluded in 2/26 cases. Bupleuri radix and Scutellariae radix were the two TCM herbs most commonly implicated. CONCLUSION In 26 (0.12%) of 21470 patients treated with herbal TCM, liver injury with ALT values of ≥ 5 × ULN was found, which normalized shortly following treatment cessation, also substantiating causality.

Gram-negative pathogen–induced nosocomial infections and resistance are a most serious menace to global public health. Qingfei Xiaoyan Wan (QF), a traditional Chinese medicine (TCM) formula, has been used clinically in China for the treatment of upper respiratory tract infections, acute or chronic bronchitis and pulmonary infection. In this study, the effects of QF on Pseudomonas aeruginosa–induced acute pneumonia in mice were evaluated. The mechanisms by which four typical anti-inflammatory ingredients from QF, arctigenin (ATG), cholic acid (CLA), chlorogenic acid (CGA) and sinapic acid (SPA), regulate anti-inflammatory signaling pathways and related targets were investigated using molecular biology and molecular docking techniques. The results showed that pretreatment with QF significantly inhibits the release of cytokines (TNF-α and IL-6) and chemokines (IL-8 and RANTES), reduces leukocytes recruitment into inflamed tissues and ameliorates pulmonary edema and necrosis. In addition, ATG was identified as the primary anti-inflammatory agent with action on the PI3K/AKT and Ras/MAPK pathways. CLA and CGA enhanced the actions of ATG and exhibited synergistic NF-κB inactivation effects possibly via the Ras/MAPK signaling pathway. Moreover, CLA is speculated to target FGFR and MEK firstly. Overall, QF regulated the PI3K/AKT and Ras/MAPK pathways to inhibit pathogenic bacterial infections effectively. PMID:27175332

The assessing contents of the health related quality of life (HRQOL) and the patient reported outcomes (PRO) are identical with the inquiry of traditional Chinese medicine (TCM), which are uniformly soft indicators which could be evaluated with the scales for instruments. The assessing method for the soft indicator in the HRQOL and PRO was gradually accepted by TCM practitioners and applied in evaluating the curative effect of TCM. The applying scale in the assessment of curative effect of TCM and the developing scale with the TCM features just started in the TCM field. There was much inadequacy in the scale study, such as no penetrating understanding of the theory and connotation of the scale in the HRQOL and PRO, on scale system for TCM, no direction in selecting scale, not standardizing in the design of the study with scale in the practice. So, it is necessary that the international guideline of developing scale applied for worldwide should be carried out in the study for developing scale. Meanwhile, it must also be under the guidance of TCM theory in the whole course. It will promote the normalization development of applying scale in the assessment of curative effect in the TCM practice.

Metabolomics is the comprehensively study of chemical processes involving small molecule metabolites. It is an important part of systems biology, and is widely applied in complex traditional Chinese medicine（TCM）system. Metabolites biosynthesized by medicinal plants are the effective basis for TCM. Metabolomics studies of medicinal plants will usher in a new period of vigorous development with the implementation of Herb Genome Program and the development of TCM synthetic biology. This manuscript introduces the recent research progresses of metabolomics technology and the main research contents of metabolomics studies for medicinal plants, including identification and quality evaluation for medicinal plants, cultivars breeding, stress resistance, metabolic pathways, metabolic network, metabolic engineering and synthetic biology researches. The integration of genomics, transcriptomics and metabolomics approaches will finally lay foundation for breeding of medicinal plants, R&D, quality and safety evaluation of innovative drug.

Nowadays, more and more Chinese medicine practices are applied in the world and popularizing that becomes an urgent task. To meet the requiremets, an increasing number of Chinese - English traditional medicine dictionaries have been produced at home or abroad in recent decades. Nevertheless, the users are still struggling to spot the information in dictionaries. What traditional medicine dictionaries are needed for the English speakers now? To identify an entry model for online TCM dictionaries, I compared the entries in five printed traditional medicine dictionaries and two online ones. Based upon this, I tentatively put forward two samples, “阳经 (yángjīng)” and “阴经 (yīn jīng)”, focusing on concepts transmitting, for online Chinese - English TCM dictionaries. PMID:29875861

Currently, the chemical fingerprint comparison and analysis is mainly based on professional equipment and software, it’s expensive and inconvenient. This study aims to integrate QR (Quick Response) code with quality data and mobile intelligent technology to develop a convenient query terminal for tracing quality in the whole industrial chain of TCM (traditional Chinese medicine). Three herbal medicines were randomly selected and their chemical two-dimensional barcode (2D) barcodes fingerprints were constructed. Smartphone application (APP) based on Android system was developed to read initial data of 2D chemical barcodes, and compared multiple fingerprints from different batches of same species or different species. It was demonstrated that there were no significant differences between original and scanned TCM chemical fingerprints. Meanwhile, different TCM chemical fingerprint QR codes could be rendered in the same coordinate and showed the differences very intuitively. To be able to distinguish the variations of chemical fingerprint more directly, linear interpolation angle cosine similarity algorithm (LIACSA) was proposed to get similarity ratio. This study showed that QR codes can be used as an effective information carrier to transfer quality data. Smartphone application can rapidly read quality information in QR codes and convert data into TCM chemical fingerprints. PMID:27780256

Scientific evaluation of traditional Chinese medicine under DSHEA: a conundrum. Dietary Supplement Health and Education Act.

PubMed

Chang, J

1999-04-01

In the United States, traditional Chinese medicines (TCM) are currently sold as dietary supplements, as defined by The Dietary Supplement Health and Education Act (DSHEA). This legislation is unique to the United States and while "structure and function" claims are allowable under DSHEA, disease claims are not. The narrow definition, however, poses a challenge to designing appropriate clinical studies that can provide data for "structure and function" claim substantiation. The process of melding Chinese herbal medicines into the dietary supplement category is complex and there is a need to define a clinical trial paradigm carefully that addresses "structure and function claims" without sacrificing scientific rigor. It is frequently not recognized that TCM favors an amalgamation of several herbs to generate the putative clinical effect. Because of this historical multiherb approach, the reliance on retrospective data to support the potential health benefits of an herb extract has severe limitations. Notwithstanding the immense value of identifying the pharmacological activity of a TCM herb to a chemical suitable for pharmaceutical development, another approach to safe and efficacious herbal products is to develop a standardized herbal extract. This article highlights issues related to the latter approach and will discuss a research-based strategy that may be suitable for validating, in part, the putative health benefits of TCM.

We investigated the syndromes of the Sini decoction pattern (SDP), a common ZHENG in traditional Chinese medicine (TCM). The syndromes of SDP were correlated with various severe Yang deficiency related symptoms. To obtain a common profile for SDP, we distributed questionnaires to 300 senior clinical TCM practitioners. According to the survey, we concluded 2 sets of symptoms for SDP: (1) pulse feels deep or faint and (2) reversal cold of the extremities. Twenty-four individuals from Taipei City Hospital, Linsen Chinese Medicine Branch, Taiwan, were recruited. We extracted the total mRNA of peripheral blood mononuclear cells from the 24 individuals for microarray experiments. Twelve individuals (including 6 SDP patients and 6 non-SDP individuals) were used as the training set to identify biomarkers for distinguishing the SDP and non-SDP groups. The remaining 12 individuals were used as the test set. The test results indicated that the gene expression profiles of the identified biomarkers could effectively distinguish the 2 groups by adopting a hierarchical clustering algorithm. Our results suggest the feasibility of using the identified biomarkers in facilitating the diagnosis of TCM ZHENGs. Furthermore, the gene expression profiles of biomarker genes could provide a molecular explanation corresponding to the ZHENG of TCM. PMID:27200105

In the People's Republic of China, both western medicine (WM) and traditional Chinese medicine (TCM) are the main treatment and rehabilitation options for cancer patients. This study aimed to explore cancer survivors' perspectives and experience of treatment and rehabilitation, in order to promote patient-centered activities of treatment and rehabilitation. Using a qualitative research approach, 68 cancer survivors were recruited from eight community cancer rehabilitation organizations in Shanghai, People's Republic of China. Eight focus group interviews were conducted. All these interviews were transcribed verbatim, and the data were analyzed by theme analysis. WM was the main choice in treatment phase though study participants noted more side effects. TCM was primarily used in the recovery phase. The lack of communication between doctors and cancer patients appears to affect treatment adherence and impair the doctor-patient relationship. WM was expensive for diagnostic procedures and treatment, while the cumulative costs of frequent use of TCM in the long rehabilitation period were also high. Both treatment options created significant perceived economic burden on patients. Conflicting information about dietary supplements tended to make cancer survivors confused. Improving the communication between doctors and cancer patients helps to ameliorate cancer patient adherence and the effect of treatments. It is essential to educate cancer patients about the effect and cost of both WM and traditional TCM. Meanwhile, marketing management and guidance to consumers regarding use of dietary supplements in the cancer rehabilitation field are also necessary.

Unlike Western medicine that generally uses purified compounds and aims to target a single molecule or pathway, traditional Chinese medicine (TCM) compositions usually comprise multiple herbs and components that are necessary for efficacy. Despite the very long-time and wide-spread use of TCM, there are very few direct comparisons of TCM and standard cytotoxic chemotherapy. In the present report, we compared the efficacy of the TCM herbal mixture LQ against lung cancer in mouse models with doxorubicin (DOX) and cyclophosphamide (CTX). LQ inhibited tumor size and weight measured directly as well as by fluorescent-protein imaging in subcutaneous, orthotopic, spontaneous experimental metastasis and angiogenesis mouse models of lung cancer. LQ was efficacious against primary and metastatic lung cancer without weight loss and organ toxicity. In contrast, CTX and DOX, although efficacious in the lung cancer models caused significant weight loss, and organ toxicity. LQ also had anti-angiogenic activity as observed in lung tumors growing in nestin-driven green fluorescent protein (ND-GFP) transgenic nude mice, which selectively express GFP in nascent blood vessels. Survival of tumor-bearing mice was also prolonged by LQ, comparable to DOX. In vitro, lung cancer cells were killed by LQ as observed by time-lapse imaging, comparable to cisplatinum. LQ was more potent to induce cell death on cancer cell lines than normal cell lines unlike cytotoxic chemotherapy. The results indicate that LQ has non-toxic efficacy against metastatic lung cancer.

The efficacy of traditional Chinese medicine (TCM) is based on the combined effects of its constituents. Variation in chemical composition between batches of TCM has always been the deterring factor in achieving consistency in efficacy. The batch mixing process can significantly reduce the batch-to-batch quality variation in TCM extracts by mixing them in a well-designed proportion. However, reducing the quality variation without sacrificing too much of the production efficiency is one of the challenges. Accordingly, an innovative and practical batch mixing method aimed at providing acceptable efficiency for industrial production of TCM products is proposed in this work, which uses a minimum number of batches of extracts to meet the content limits. The important factors affecting the utilization ratio of the extracts (URE) were studied by simulations. The results have shown that URE was affected by the correlation between the contents of constituents, and URE decreased with the increase in the number of targets and the relative standard deviations of the contents. URE could be increased by increasing the number of storage tanks. The results have provided a reference for designing the batch mixing process. The proposed method has possible application value in reducing the quality variation in TCM and providing acceptable production efficiency simultaneously. PMID:24190450

Increasing attention has been attracted to intestinal microbiota, due to interactions with nutrition, metabolism and immune defence of the host. Traditional Chinese medicine (TCM) feed additives have been applied in aquaculture to improve fish health, but the interaction with fish gut microbiota is still poorly understood. This study aimed to explore the effect of adding TCM in feed on the intestinal microbiota of gibel carp (Carassius auratus gibelio). Bacterial communities of 16 fish intestinal contents and one water sample were characterized by high-throughput sequencing and analysis of the V4-V5 region of the 16S rRNA gene. The results showed that the composition and structure of the bacterial community were significantly altered by the TCM feeding. Some phyla increased markedly (Proteobacteria, Actinobacteria, Acidobacteria, etc.), while Fusobacteria were significantly reduced. Concurrently, the richness and diversity of the taxonomic units increased, and the microbiota composition of TCM-treated fish was more homogeneous among individuals. At the genus level, the addition of TCM tended to reduce the incidence of potential pathogens (Aeromonas, Acinetobacter and Shewanella), while stimulating the emergence of some potential probiotics (Lactobacillus, Lactococcus, Bacillus and Pseudomonas). These data suggested that the feed additive could regulate the fish intestinal microbiota by reinforcing the microbial balance. This study may provide useful information for further application of TCM for diseases prevention and stress management in aquaculture. © 2017 The Society for Applied Microbiology.

To help researchers selecting appropriate data mining models to provide better evidence for the clinical practice of Traditional Chinese Medicine (TCM) diagnosis and therapy. Clinical issues based on data mining models were comprehensively summarized from four significant elements of the clinical studies: symptoms, symptom patterns, herbs, and efficacy. Existing problems were further generalized to determine the relevant factors of the performance of data mining models, e.g. data type, samples, parameters, variable labels. Combining these relevant factors, the TCM clinical data features were compared with regards to statistical characters and informatics properties. Data models were compared simultaneously from the view of applied conditions and suitable scopes. The main application problems were the inconsistent data type and the small samples for the used data mining models, which caused the inappropriate results, even the mistake results. These features, i.e. advantages, disadvantages, satisfied data types, tasks of data mining, and the TCM issues, were summarized and compared. By aiming at the special features of different data mining models, the clinical doctors could select the suitable data mining models to resolve the TCM problem.

A"special issue of female physicians" was included in the 1934 Kunghwa Medical Journal. In 1939, Qian Bao-hua, together with a batch of female TCM professional medical workers, inaugurated a "Chinese Feminine Physicians" included in the "Journal of Column of Traditional Chinese Medicine". The former one was published independently in 1941, only for 8 issues and was suspended in the same year. In the Republican period, the 7 years of running the TCM periodicals by the female physicians was the miniature of the campaign of feminine rights in the TCM field from heat to cold, from foolish through confidence to self-realization. As the only extant TCM periodical, the Chinese Feminine Physicians run by females in the upper half of the 20th century, the basic cause of its failure may lie on the wrong evaluation of its audiences.

Sasang constitutional medicine (SCM) is a holistic typological constitution medicine which balances psychological, social, and physical aspects of an individual to achieve wellness and increase longevity. SCM has the qualities of preventative medicine, as it emphasizes daily health management based on constitutionally differentiated regimens and self-cultivation of the mind and body. This review's goal is to establish a fundamental understanding of SCM and to provide a foundation for further study. It compares the similarities and differences of philosophical origins, perspectives on the mind (heart), typological systems, pathology, and therapeutics between SCM and traditional Chinese medicine (TCM). TCM is based on the Taoist view of the universe and humanity. The health and longevity of an individual depends on a harmonious relationship with the universe. On the other hand, SCM is based on the Confucian view of the universe and humanity. SCM focuses on the influence of human affairs on the psyche, physiology, and pathology. PMID:21941592

To investigate menopause-related symptoms, traditional Chinese Medicine (TCM)-diagnosis and hormone status of two comparable urban samples of menopausal women, one in Essen (Germany) and the other in Shanghai (China). Patients suffering from menopause-syndrome were recruited from the TCM-outpatient clinic of the University of Duisburg-Essen in Germany (35 subjects) and from the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine in China (35 subjects). The Kupperman-Index for tracing menopausal symptoms was applied. The complete TCM-diagnosis was carried out by the same investigator in China as well as in Germany. Testosterone and estrogen blood samples were collected once from every woman. There were significant differences in specific symptoms of the Kupperman-Index, such as a higher prevalence of formication and depression in German menopausal women; whereas Chinese menopausal women suffered significantly more from vertigo, headache and paraesthesia symptoms. Concerning TCM-diagnosis, Shen ()-yang deficiency was diagnosed in 51.43% of the German women in contrast to 5.71% of the Chinese women; 17.14% of the German women were diagnosed as having Shen-yin deficiency compared to 74.29% of the Chinese women. The German women showed significantly lower mean hormone levels for testosterone compared to the Chinese women (P

The aim of this review is to critically examine the clinical trial research on Traditional Chinese Medicine (TCM) as an intervention in treating heroin addiction in People's Republic of China. This review examines Chinese-language-only publications for the patent medicines: Shenfu Tuodu, Fukang Pian, and Shifu Sheng. Other compound medicines will be reviewed in future publications. A systematic review of the literature was conducted in Western and Chinese databases. Most trials were excluded because they did not declare randomization and had poor methodology or reporting. The majority of clinical evidence in the random controlled trials demonstrates good evidence for TCM patent medicines in heroin addiction treatment. When compared to typical Western medications, TCMs demonstrate fewer side-effects, in addition to equal measures of treatment efficacy and safety.

Chinese medicine syndrome (CMS, “ZHENG” in Chinese) is an understanding of the regularity of disease occurrence and development as well as a certain stage of a comprehensive response of patients with body condition. However, because of the complexity of CMS and the limitation of present investigation method, the research for deciphering the scientific basis and systematic features of CMS is difficult to go further. Metabolomics enables mapping of early biochemical changes in disease and hence provides an opportunity to develop predictive biomarkers. Moreover, its method and design resemble those of traditional Chinese medicine (TCM) which focuses on human disease via the integrity of close relationship between body and syndromes. In the systemic context, metabolomics has a convergence with TCM syndrome; therefore it could provide useful tools for exploring essence of CMS disease, facilitating personalized TCM, and will help to in-depth understand CMS. The integration of the metabolomics and CMS aspects will give promise to bridge the gap between Chinese and Western medicine and help catch the traditional features of CMS. In this paper, particular attention will be paid to the past successes in applications of robust metabolomic approaches to contribute to low-molecular-weight metabolites (biomarkers) discovery in CMS research and development.

Researches on the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine are becoming a hot spot in andrology, but many recent studies of this kind have failed to explain the connotation of integrated traditional Chinese and Western medicine in andrology. Related existing problems include repeated researches into the same indexes of action mechanisms of different therapeutic principles of traditional Chinese medicine (TCM), Chinese herbal compound and special prescriptions, studies focusing on individual diseases but ignoring symptoms, immature syndrome models for studies of mechanisms, and too much attention to uncertain or immature target mechanisms. The stress should be placed on the action mechanisms of Chinese herbal compound and special prescriptions on male diseases and, what is more important, on the clarification of the essential principles of differentiation and treatment of TCM syndromes. In the recent years, proteomics, genomics, transcriptomics and metabolomics have shed some light upon researches into the mechanisms underlying the therapeutic effects of the disease-syndrome combination approach in integrated traditional Chinese and Western medicine in andrology. An insight into the TCM syndrome, a macroscopic inductive analysis, and a comprehension of such microcosmic aspects as the gene, protein, metabolism and metagenome may contribute to some breakthroughs and new ideas in the studies of disease-syndrome combination in integrated traditional Chinese and Western medicine in andrology.

A wide array of wildlife species, including many animals, are used in traditional medicines across many medicinal systems, including in Traditional Chinese Medicine (TCM). Due to over-exploitation and habitat loss, the populations of many animals commonly used in TCM have declined and are unable to meet market demand. A number of measures have been taken to try to reduce the impact that this large and growing market for TCM may have on wild animal species. Consumer preferences and behavior are known to play an important role in the consumption and protection of wild animals used in traditional medicine, and thus are likely to be an important factor in the success of many of these mechanisms--particularly given the significant percentage of TCMs that are over-the-counter products (access to which is not mediated by practitioners). In this study we conducted questionnaires and designed stated preference experiments embodying different simulation scenarios using a random sample of the population in Beijing to elicit individuals' knowledge, perceptions and preferences toward wild or farmed animal materials and their substitutes used in traditional Chinese medicine. We found that respondents had a stated preference for wild materials over farm-raised and other alternatives because they believe that the effectiveness of wild-sourced materials is more credible than that of other sources. However, we also found that, although respondents used TCM products, they had a poor understanding of the function or composition of either traditional Chinese medicines or proprietary Chinese medicines (PCM), and paid little attention to the composition of products when making purchasing decisions. Furthermore, awareness of the need for species protection, or "conservation consciousness" was found to play an important role in willingness to accept substitutions for wild animal materials, while traditional animal medicinal materials (TAMs) derived from well-known endangered species, such as bear bile and tiger bone, show relatively higher substitutability. These results suggest that there is still hope for conservation measures which seek to promote a transition to farmed animal, plant and synthetic ingredients and provide clear directions for future social marketing, education and engagement efforts.

Action (" gongxiao " in Chinese) of traditional Chinese medicine (TCM) is the high recapitulation for therapeutic and health-preserving effects under the guidance of TCM theory. TCM-defined herbal properties (" yaoxing " in Chinese) had been used in this research. TCM herbal property (TCM-HP) is the high generalization and summary for actions, both of which come from long-term effective clinical practice in two thousands of years in China. However, the specific relationship between TCM-HP and action of TCM is complex and unclear from a scientific perspective. The research about this is conducive to expound the connotation of TCM-HP theory and is of important significance for the development of the TCM-HP theory. One hundred and thirty-three herbs including 88 heat-clearing herbs (HCHs) and 45 blood-activating stasis-resolving herbs (BAHRHs) were collected from reputable TCM literatures, and their corresponding TCM-HPs/actions information were collected from Chinese pharmacopoeia (2015 edition). The Kennard-Stone (K-S) algorithm was used to split 133 herbs into 100 calibration samples and 33 validation samples. Then, machine learning methods including supported vector machine (SVM), k-nearest neighbor (kNN) and deep learning methods including deep belief network (DBN), convolutional neutral network (CNN) were adopted to develop action classification models based on TCM-HP theory, respectively. In order to ensure robustness, these four classification methods were evaluated by using the method of tenfold cross validation and 20 external validation samples for prediction. As results, 72.7-100% of 33 validation samples including 17 HCHs and 16 BASRHs were correctly predicted by these four types of methods. Both of the DBN and CNN methods gave out the best results and their sensitivity, specificity, precision, accuracy were all 100.00%. Especially, the predicted results of external validation set showed that the performance of deep learning methods (DBN, CNN) were better than traditional machine learning methods (kNN, SVM) in terms of their sensitivity, specificity, precision, accuracy. Moreover, the distribution patterns of TCM-HPs of HCHs and BASRHs were also analyzed to detect the featured TCM-HPs of these two types of herbs. The result showed that the featured TCM-HPs of HCHs were cold, bitter, liver and stomach meridians entered, while those of BASRHs were warm, bitter and pungent, liver meridian entered. The performance on validation set and external validation set of deep learning methods (DBN, CNN) were better than machine learning models (kNN, SVM) in sensitivity, specificity, precision, accuracy when predicting the actions of heat-clearing and blood-activating stasis-resolving based on TCM-HP theory. The deep learning classification methods owned better generalization ability and accuracy when predicting the actions of heat-clearing and blood-activating stasis-resolving based on TCM-HP theory. Besides, the methods of deep learning would help us to improve our understanding about the relationship between herbal property and action, as well as to enrich and develop the theory of TCM-HP scientifically.

Intricate health problems, such as insulin resistance (IR) and its associated diseases, call for multi-targeted therapies with few side effects. Based on traditional Chinese medicine (TCM), Dai-Zong-Fang (DZF) is an herbal formula mainly composed of Rhizoma Coptidis (Huanglian) and Fructus Aurantii Immaturus (Zhishi), of which berberine and naringin are the main constituents. Though DZF has been clinically used for treatment of IR and metabolic syndrome for decades, its mechanism in vivo remains unknown. In the present study, we observed that both DZF and metformin, the first-line drug for type 2 diabetes, ameliorated insulin resistance with significant improvement of oral glucose tolerance test (OGTT) and homeostasis model assessment of IR (HOMA-IR) level in diabetic C57BL/Ksj-Lepr db -/- ( db/db ) mice. Low-density lipoprotein cholesterol (LDL-C) and fatty acids (FAs) also decreased in the blood. Higher dose of DZF (1 g·kg -1 ), but not metformin (0.25 g·kg -1 ), alleviated hepatic steatosis with reduced liver weight and hepatic lipid accumulation and provided protection from hepatic injury with lower alanine aminotransferase and aspartate aminotransferase and increased hepatic superoxide dismutase activity in db/db mice. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) showed a decrease in FA synthase gene ( Fasn ) and an increase in FA oxidation gene Ppara expression. Western blot demonstrated that both DZF and metformin activated 5' AMP-activated protein kinase (AMPK) but inhibited Notch intracellular domain (NICD) and Hairy/enhancer-of-split 1 (Hes1) of Notch signaling pathway in the liver. DZF also dramatically improved the ultrastructure of skeletal muscles, AMPK phosphorylation, and GLUT4 translocation. DZF also promoted FA transport and oxidation with Cd36 and Cpt1b up-regulation in the skeletal muscle. In conclusion, DZF improves insulin sensitivity by reducing hepatic lipids through AMPK activation and Notch signal pathway inhibition and enhancing energy metabolism in the skeletal muscle via AMPK. This study provides insights into the treatment of complex conditions, such as IR, where TCM herbal formulas exert multipronged effects through correlating pathways.

Amyotrophic lateral sclerosis (ALS) is a chronic, fatal neurodegenerative disease which leads to progressive muscle atrophy and paralysis. In order to summarize the characteristics of Traditional Chinese Medicine compounds and their preparations in the prevention and treatment of ALS through analyzing the mechanism, action site, and symptoms according to effective clinical research. We searched ALS, motor neuron disease, chemical drugs, herbal medicine, Chinese medicine, Traditional Chinese Medicine (TCM), and various combinations of these terms in databases including the PudMed, Springer, Ovid, Google, China National Knowledge Infrastructure, and Wanfang databases. It was found that the chemical drugs almost had not sufficient evidence to show their effectiveness in the treatment of ALS, except RILUZOLE. According to the characteristics of clinical symptoms of ALS, Chinese medicine practitioners believe that this disease belongs to the category of "atrophic disease". In clinical research, many Chinese herbal formulas had good clinical efficacies in the treatment of ALS with multiple targets, multiple links, and few side effects. And four kinds of dialectical treatment had been developed based on Clinical data analysis and the use of dialectical therapy: Benefiting the kidney; Declaring the lungs; Enhancing the Qi; and Dredging the meridian. In this review, we provide an overview of chemical drugs and Traditional Chinese Medicine compound and its preparations in therapy of ALS as well as how they may contribute to the ALS pathogenesis, thereby offering some clues for further studies.

Abstract Syndrome of Chinese medicine is an understanding of the regularity of disease occurrence and development and its performance of symptoms. Syndrome is the key to recognize diseases and the foundation to treat them. However, because of the complexity of the concept and the limitation of present investigations, the research of syndrome is hard to go further. Proteomics has been received extensive attention in the area of medical diagnosis and drug development. In the holistic and systemic context, proteomics have a convergence with traditional Chinese medicine (TCM) syndrome, which could overcome the one-sidedness and singleness of TCM and avoid the complication and tedious processes. Chinese medicine has a wealth of experience and proteomics has a substantial research potential, the integration of the two aspects will bring a great enhancement of our knowledge of disease.

Although toxic, the Chinese medicinal herb Xanthii Fructus (XF) is commonly used to treat traditional Chinese medicine (TCM) symptoms that resemble cold, sinusitis and arthritis. According to TCM theory, stir-baking (a processing method) can reduce the toxicity and enhance the efficacy of XF. Cytotoxicities of raw XF and processed XF (stir-baked XF, SBXF) were determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay in normal liver derived MIHA cells. Nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) mRNA expression were measured by the Griess reagent and quantitative real-time PCR, respectively. The chemical profiles of XF and SBXF were compared using an established ultra-performance liquid chromatography/quadrupole-time-of-flight mass spectrometry (UPLC/Q-TOF-MS) method. SBXF was less toxic than XF in MIHA cells. Both XF and SBXF had anti-inflammatory effects as demonstrated by their abilities to reduce nitric oxide production as well as inducible nitric oxide synthase mRNA expression in lipopolysaccharide-stimulated RAW 264.7 macrophages. Interestingly, the anti-inflammatory effects of SBXF were more potent than that of XF. By comparing the chemical profiles, we found that seven peaks were lower, while nine other peaks were higher in SBXF than in XF. Eleven compounds including carboxyatractyloside, atractyloside and chlorogenic acid corresponding to eleven individual changed peaks were tentatively identified by matching with empirical molecular formulae and mass fragments, as well as literature data. Our study showed that stir-baking significantly reduced the cytotoxicity and enhanced the anti-inflammatory effects of XF; moreover, with a developed ultra-performance liquid chromatography/quadrupole-time-of-flight mass spectrometry method we differentiated XF and SBXF by their chemical profiles. Further studies are warranted to establish the relationship between the alteration of chemical profiles and the changes of medicinal properties caused by stir-baking.

This study was completed by the research and promotion base for traditional Chinese medicine(TCM) standard. The methods of applicability evaluation and application evaluation were used in the study. The questionnaires were filled out to evaluate applicability of the guideline, including doctor's familiarity with the guideline,the quality of the guideline, applicable conditions and clinical applications. The prospective case study analysis method was used to evaluate application of the guideline, including evaluation of clinical application compliance and application results(such as clinical effects, safety and economy). There were two parts in the guideline, which were TCM guideline and Western medicine guideline. The results of applicability evaluation showed that there were no obvious differences between TCM guideline and Western medicine guideline in doctor's familiarity with guideline(85.43%, 84.57%) and the use of the guideline(52.10%, 54.47%); the guidelines with good quality, and higher scores in the scope of application and the use of the term rationality(91.94%, 93.35%); the rationality scores of relevant contents in syndrome differentiation and treatment were more than 75%; the applicable conditions were better, and the safety score was the the highest. The comprehensive applicability evaluation showed that the proportion of the application of TCM guideline and Western medicine guideline were 77.73%, 75.46%, respectively. The results of application evaluation showed that there was high degree coincidence between the guideline with its clinical application; except for "other treatment" and "recuperation and prevention" in TCM, other items got high scores which were more than 90%; in the evaluation of application effects, safety of the guideline was best, economy of the guideline was better, and clincal effect was good. The comprehensive application evaluation showed that 75%~80% doctors were satisfied with the guideline. The Guidelines for Diagnosis and Treatment of Internal Diseases in Traditional Chinese Medicine has been widely used in clinical practice, which is of high quality, high degree of clinical application,good safety and economy. But there were some disadvantages of the guideline such as lack of evidence-based medicine and innovation, which is need to be improved constantly in the guideline revision.

Danggui Buxue Tang (DBT) is a Traditional Chinese Medicine (TCM) formula primarily used to treat symptoms associated with menopause in women. Usually, DBT is composed of one portion of Radix Angelicae Sinensis (RAS) and five portions of Radix Astragali (RA). Clinically, Radix Hedysari (RH) is sometimes used by TCM physicians to replace RA in DBT. In order to verity whether the chemical constituents of the DBT1 (RA:RAS = 5:1, w/w) and DBT2 (RH:RAS = 5:1, w/w) share similarities the chemical profiles of the two DBTs crude extracts and urine samples were analyzed and compared with the aid of HPLC-DAD-ESI-IT-TOF-MSn, which determines the total ion chromatogram (TIC) and multi-stage mass spectra (MSn). Then, the DBT1 and DBT2 were identified and compared on the basis of the TIC and the MSn. In the first experiment (with crude extracts), 69 compounds (C1-C69) were identified from the DBT1; 46 compounds (c1-c46) were identified from the DBT2. In the second experiment(with urine samples), 44 compounds (M1-M44) were identified from the urine samples of rats that had been administered DBT1, and 34 compounds (m1-m34) were identified from the urine samples of rats that had been administered DBT2. Identification and comparison of the chemical compositions were carried out between the DBT1 and DBT2 of the crude extracts and urine samples respectively. Our results showed that the two crude extracts of the DBTs have quite different chemical profiles. The reasons for their differences were that the special astragalosides in DBT1 and the isoflavonoid glycosides formed the malonic acid esters undergo single esterification and acetyl esters undergo acetylation in DBT1. In contrast, the urine from DBT1-treated rats strongly resembled that of DBT2-treated rats. These metabolites originate mainly from formononetin, calycosin and their related glycosides, and they were formed mainly by the metabolic process of reduction, deglycosylation, demethylation, hydrogenation and sulfation. The HPLC-DAD-ESI-IT-TOF-MSn method was successfully applied for the rapid chemical profiles evaluation of two DBTs and their related urine samples.

One important, however, poorly understood, concept of Traditional Chinese Medicine (TCM) is that of hot, cold, and neutral nature of its bioactive principles. To advance the field, in this study, we analyzed compound-nature pairs from TCM on a large scale (>23 000 structures) via chemical space visualizations to understand its physicochemical domain and in silico target prediction to understand differences related to their modes-of-action (MoA) against proteins. We found that overall TCM natures spread into different subclusters with specific molecular patterns, as opposed to forming coherent global groups. Compounds associated with cold nature had a lower clogP and contain more aliphatic rings than the other groups and were found to control detoxification, heat-clearing, heart development processes, and have sedative function, associated with "Mental and behavioural disorders" diseases. While compounds associated with hot nature were on average of lower molecular weight, have more aromatic ring systems than other groups, frequently seemed to control body temperature, have cardio-protection function, improve fertility and sexual function, and represent excitatory or activating effects, associated with "endocrine, nutritional and metabolic diseases" and "diseases of the circulatory system". Compounds associated with neutral nature had a higher polar surface area and contain more cyclohexene moieties than other groups and seem to be related to memory function, suggesting that their nature may be a useful guide for their utility in neural degenerative diseases. We were hence able to elucidate the difference between different nature classes in TCM on the molecular level, and on a large data set, for the first time, thereby helping a better understanding of TCM nature theory and bridging the gap between traditional medicine and our current understanding of the human body.

Content validity is crucial in quality of life instrument development but there is very little literature on this in Chinese culture. The Chinese Quality of Life Instrument (ChQOL) was developed in Mainland China to capture the health-related quality of life (HRQOL) concepts specific to traditional Chinese medicine (TCM). The aim of this study was to evaluate the content validity of ChQOL in a Chinese population whose spoken dialect and health-care system are different from those of Mainland China to find out whether the instrument is generalizable. 8 TCM practitioners and 10 patients rated the clarity, relevance and appropriateness of each of the 50 items of the ChQOL (HK version), and completed qualitative cognitive debriefing interviews. The content of ChQOL was rated valid by TCM practitioners with CVIs on clarity, relevance and appropriateness ranging from 80 to 100%. 49 out of 50 items were well understood by patients, but 12 items had CVI on relevance and 5 items had CVI on appropriateness lower than 70% among patients. After reviewing the patients and TCM practitioners' opinions, revisions were made for three items (2, 8 and 29) to form the ChQOL (HK version)-2008. In general, the ChQOL was found to be too long which called for shorter version. The content of ChQOL was shown to be really valid in the context of Chinese Medicine for Cantonese speaking Chinese. There was some discrepancy between the judgments of TCM practitioners and patients indicating the importance of evaluation by both experts and lay persons.

Prof. MA Rou, as a hematology specialist of integrative medicine (IM), uses modern medical equipment to diagnose diseases and takes traditional Chinese medical methods to treat diseases. He is loyal to TCM sciences and refers to the advantages of WM. He holds the essence of MDS lies in toxic stasis according to its pathogenic features. He detoxifies and removes stasis using Qinghuang Powder. Meanwhile, according to patients' clinical manifestations, he summarized two common syndrome types, Pi-Shen yang deficiency syndrome and Gan-Shen yin deficiency syndrome. Better efficacy could be achieved by combining Chinese herbs for tonifying Pi-Shen. In recent years the application of Qinghuang Powder won some achievements in clinical study and experimental study, thus providing scientific reliance for Prof. MA Rou's academic thought on treating MDS.

The actual concern about the safety and efficacy of herbal drugs originating from traditional Chinese medicine (TCM) is based on observations that these medicinal plants may have a high risk potential due to insufficient definitions, problems with identity, purity and falsifications. No uniform legal status for these groups of herbal drugs currently exists in the European Union. For quality control, monographs for TCM herbs can mainly be found in the Pharmacopoeia of the Peoples Republic of China. Based on these facts the Commission of the European Pharmacopoeia decided in 2005 to establish TCM-herbal drug monographs for the most important medicinal plants imported from Far East. These new monographs had to be established and evaluated on the basis of existing monographs in the Chinese Pharmacopoeia (ChP), English edition 2005. Due to important differences in the overall features of EP and ChP, a simple adapt/adopt procedure was not feasible. Therefore, specialist groups were mandated with a corresponding working programme. Some results and actual problems related to this working programme will be presented and discussed. © Georg Thieme Verlag KG Stuttgart · New York.

Abstract Background The Cochrane Collaboration, an international not-for-profit organization that prepares and maintains systematic reviews of randomized trials of health care therapies, has produced reviews summarizing much of the evidence on Traditional Chinese Medicine (TCM). Our objective was to review the evidence base according to Cochrane systematic reviews. Methods In order to detect reviews focusing on TCM, we searched the titles and abstracts of all reviews in Issue 4, 2008 of the Cochrane Database of Systematic Reviews. For each review, we extracted data on the number of trials included and the total number of participants. We provided an indication of the strength of the review findings by assessing the reviewers' abstract conclusions statement. We supplemented our assessment of the abstract conclusions statements with a listing of the comparisons and outcomes showing statistically significant meta-analyses results. Results We identified 70 Cochrane systematic reviews of TCM, primarily acupuncture (n = 26) and Chinese herbal medicine (n = 42), and 1 each of moxibustion and t'ai chi. Nineteen (19) of 26 acupuncture reviews and 22/42 herbal medicine reviews concluded that there was not enough good quality trial evidence to make any conclusion about the efficacy of the evaluated treatment, while the remaining 7 acupuncture and 20 herbal medicine reviews and each of the moxibustion and t'ai chi reviews indicated a suggestion of benefit, which was qualified by a caveat about the poor quality and quantity of studies. Most reviews included many distinct interventions, controls, outcomes, and populations, and a large number of different comparisons were made, each with a distinct forest plot. Conclusions Most Cochrane systematic reviews of TCM are inconclusive, due specifically to the poor methodology and heterogeneity of the studies reviewed. Some systematic reviews provide preliminary evidence of Chinese medicine's benefits to certain patient populations, underscoring the importance and appropriateness of further research. These preliminary findings should be considered tentative and need to be confirmed with rigorous randomized controlled trials. PMID:19757977

Parkinson's disease (PD) is an incurable neurodegenerative disorder with a high prevalence rate worldwide. The fact that there are currently no proven disease-modifying treatments for PD underscores the urgency for a more comprehensive understanding of the underlying disease mechanism. Chemical probes have been proven to be powerful tools for studying biological processes. Traditional Chinese medicine (TCM) contains a huge reservoir of bioactive small molecules as potential chemical probes that may hold the key to unlocking the mystery of PD biology. The TCM-sourced chemical approach to PD biology can be advanced through the use of an emerging cytological profiling (CP) technique that allows unbiased characterization of small molecules and their cellular responses. This comprehensive technique, applied to chemical probe identification from TCM and used for studying the molecular mechanisms underlying PD, may inform future therapeutic target selection and provide a new perspective to PD drug discovery.

Esophageal cancer is one of the most common types of cancer in the world, and it demonstrates a distinct geographical distribution pattern in China. In the last decade, inducing apoptosis with traditional Chinese medicine (TCM) has become an active area in both fundamental and clinical research on cancer therapy. In this review, we summarize the molecular mechanisms by which TCM induces apoptosis in esophageal cancer cells. These mechanisms are generally related but not limited to targeting the extrinsic death receptor pathway, the intrinsic mitochondrial pathway, and the endoplasmic reticulum (ER) stress pathway. By using different monomers and composite prescriptions of TCM, it is possible to modulate the ratio of Bcl-2/Bax, regulate the expression of caspase proteases and mitochondrial transmembrane potential, increase the expression of Fas and p53, down-regulate NF-κB pathway and the expression of Chop and survivin, and block cell cycle progression.

Meridian theory is one of the core components of the theory of traditional Chinese medicine (TCM). It gives an integral explanation for how human life works, how a disease forms, and how a therapy acts to treat a disease. If we do not understand the meridians, it is hard to understand the TCM. People in China and abroad had been working hard for 50 years, trying to understand the meridians; then 15 years ago a breakthrough idea appeared when we realized that they are low resistance fluid channels where various chemical and physical transports take place. The channel is called low hydraulic resistance channel (LHRC) and the chemical transport is named volume transmission (VT). This review aims to give a full understanding of the essence of meridian and its works on the therapies of TCM. PMID:25821487

In previous paper, process-specific times (PSTs) are defined by use of molecular reaction dynamics and time quantum theory established by TCY Liu et al., and the change of PSTs representing two weakly nonlinearly coupled bio-processes are shown to be parallel, which is called time parallel principle (TPP). The PST of a physiological process (PP) is called physiological time (PT). After the PTs of two PPs are compared with their Yin-Yang property of traditional Chinese medicine (TCM), the PST model of Yin and Yang (YPTM) was put forward: for two related processes, the process of small PST is Yin, and the other process is Yang. The Yin-Yang parallel principle (YPP) was put forward in terms of YPTM and TPP, which is the fundamental principle of TCM. In this paper, we apply it to study TCM on the effects of low intensity laser on cells, and successfully explained observed phenomena.

To investigate Traditional Chinese Medicine (TCM) constitutions of youths in colleges, and their physical and mental health conditions of different TCM constitutions, so as to provide a theoretical basis for the TCM way to improve young people's physical and mental health. The Standard TCM Constitutions' Classification and Determination Questionnaire was used to measure the body health condition, and the Symptom Checklist 90 Questionnaire and the Questionnaire of the National Student Physical Health Standards were used to determine mental and physical health conditions respectively in 1421 young participants validly answering the questionnaires in Zhejiang Province. The participants had a mean age of 19.96 years (SD = 0.95 years) with the majority of females (55.10%). One fourth of the 1421 participants were the Ping-he constitution and others were the tendency constitutions. Participants with Pinghe module (which has characteristics of moderate posture, rosy, energetic and is a healthy condition in TCM) were healthier than those with tendency constitutions in physical and mental health, with 65.81 ± 7.83 (men) and 77.99 ± 7.24 (women) scores in the physical test and around 1.25 scores in the mental health test. College students with combined biased constitutions were more likely suffer force, sensitive, depression and anxiety. Most of college students have a tendency or biased constitution which could be more likely to suffer suboptimal health status and diseases. Youths in college themselves and health providers should pay more attention to their potential health issues and make proper healthcare plan according to their own TCM constitution.

The terminology of traditional Chinese medicine (TCM) is hardly interpretable in the context of human genome, therefore the human genome program attracted attention towards the Western practice of medicine in China. In the last two decades, several important steps could be observed in China in relation to the approach of traditional Chinese and Western medicine. The Chinese government supports the realization of information databases for research in order to clarify the molecular biology level to detect associations between gene expression signal transduction pathways and protein-protein interactions, and the effects of bioactive components of Chinese drugs and their effectiveness. The values of TCM are becoming more and more important for Western medicine as well, because molecular biological therapies did not redeem themselves, e.g., in tumor therapy.

We sought to determine the prevalence of traditional and complementary medicine (TCM) use for knee osteoarthritis and its associated factors among patients attending a referral hospital in an eastern coastal state of Malaysia. This cross-sectional study included 214 patients with knee osteoarthritis. A universal sampling method was applied to patients who attended the outpatient clinic in Hospital Universiti Sains Malaysia from May 2013 to October 2013. Participants were given a questionnaire to determine their sociodemographic information and a validated Bahasa Malaysia version of the Western Ontario and McMaster Universities Arthritis Index (WOMAC). This questionnaire was used to assess the severity of knee osteoarthritis (i.e., pain, stiffness, and disturbances in daily activity). Over half (57.9%) of patients reported using TCM to treat knee osteoarthritis. Factors associated with TCM use were gender (odd ratio (OR) = 2.47; 95% confidence interval (CI): 1.28-4.77), duration of knee osteoarthritis (OR = 1.51; 95% CI: 1.03-2.23), and the severity of knee pain (OR = 2.56; 95% CI: 1.71-3.86). The prevalence of TCM use among eastern Malaysian patients with knee osteoarthritis was high. Physicians caring for these patients should be aware of these findings so that inquiries regarding TCM use can be made and patients can be appropriately counseled.

Traditional Chinese Medicine and Herb-induced Liver Injury: Comparison with Drug-induced Liver Injury.

PubMed

Jing, Jing; Teschke, Rolf

2018-03-28

Cases of suspected herb-induced liver injury (HILI) caused by herbal Traditional Chinese Medicines (TCMs) and of drug-induced liver injury (DILI) are commonly published in the scientific literature worldwide. As opposed to the multiplicity of botanical chemicals in herbal TCM products, which are often mixtures of several herbs, conventional Western drugs contain only a single synthetic chemical. It is therefore of interest to study how HILI by TCM and DILI compare with each other, and to what extent results from each liver injury type can be transferred to the other. China is among the few countries with a large population using synthetic Western drugs as well as herbal TCM. Therefore, China is well suited to studies of liver injury comparing drugs with TCM herbs. Despite some concordance, recent analyses of liver injury cases with verified causality, using the Roussel Uclaf Causality Assessment Method, revealed major differences in HILI caused by TCMs as compared to DILI with respect to the following features: HILI cases are less frequently observed as compared to DILI, have a smaller proportion of females and less unintentional rechallenge events, and present a higher rate of hepatocellular injury features. Since many results were obtained among Chinese residents who had access to and had used Western drugs and TCM herbs, such ethnic homogeneity supports the contention that the observed differences of HILI and DILI in the assessed population are well founded.

Traditional Chinese medicine (TCM) still needs more scientific rationale to be proven for it to be accepted further in the West. We are now in the position to propose computational hypotheses for the mode-of-actions (MOAs) of 45 TCM therapeutic action (sub)classes from in silico target prediction algorithms, whose target was later annotated with Kyoto Encyclopedia of Genes and Genomes pathway, and to discover the relationship between them by generating a hierarchical clustering. The results of 10,749 TCM compounds showed 183 enriched targets and 99 enriched pathways from Estimation Score ≤ 0 and ≥ 5% of compounds/targets in a (sub)class. The MOA of a (sub)class was established from supporting literature. Overall, the most frequent top three enriched targets/pathways were immune-related targets such as tyrosine-protein phosphatase nonreceptor type 2 (PTPN2) and digestive system such as mineral absorption. We found two major protein families, G-protein coupled receptor (GPCR), and protein kinase family contributed to the diversity of the bioactivity space, while digestive system was consistently annotated pathway motif, which agreed with the important treatment principle of TCM, “the foundation of acquired constitution” that includes spleen and stomach. In short, the TCM (sub)classes, in many cases share similar targets/pathways despite having different indications. PMID:26989424

Background. Chinese herbal products (CHPs) given as a therapy for symptom relief have gained widespread popularity among women with breast cancer. The aim of this study was to analyze the utilization of CHP among women with breast cancer in Taiwan. Methods. The usage, frequency of services, and CHP prescribed for breast cancer among women with breast cancer were evaluated, recruited from a randomly sampled cohort of 1,000,000 beneficiaries from the National Health Insurance Research Database. The logistic regression method was employed to estimate the odds ratios (ORs) for utilization of CHP. Results. 81.5 percent (N = 2, 236) of women with breast cancer utilized traditional Chinese medicine (TCM) and 18% of them sought TCM with the intent of treating their breast cancer. Jia-wei-xiao-yao-san (Augmented Rambling Powder) was the most frequently prescribed formula for treating breast cancer. Among the top 10 most frequently prescribed CHP for treating breast cancer, seven contained dang qui (Angelica sinensis-radix) and six contained ren shen (Panax ginseng-radix), which are reported to have potential beneficial synergistic effects on breast cancer cells. Conclusion. CHP containing dang qui (Angelica sinensis-radix) or ren shen (Panax ginseng-radix) are the most frequently prescribed for breast cancer and their effects should be taken into account by healthcare providers.

The disputes between Western and traditional Chinese medicine (TCM) started at the turn of late Qing Dynasty to early Republican China, intensified in the period of construction of National Government at Nanking, lasting for several years. The scope of dispute also extended from the initial medical area to the mass media, and even to the government interior factions. The form of the combat also changed from the debates of original scientific theory to the confrontation of political ideology. It was the government interior factional disputes which caused "the case of abolition of the traditional Chinese medicine" to abort objectively, with the difficult advent of the regulations which saved TCM, to certain degree, from vanishing.

The present note provides an overview of the historical development of neurology and its current status in the People's Republic of China, against the backdrop of the current massive transformation of Chinese society. We trace the origins of neurology in China to missionary medicine during the Republican period (1911-1949), and describe how the discipline grows with difficulty throughout the subsequent decades (1950-1976). We then introduce an influential legacy of the post-revolutionary period, the ideal of integrating traditional Chinese medicine (TCM) and Western medicine, and briefly describe recent efforts to modernize medical education and training. Finally, we provide a brief overview of topics in neurology and neuropsychiatry that have a 'Chinese face', last but not least the successful integration of TCM and Western medicine in the treatment of hepatolenticular degeneration/Wilson's disease.

In this study, the applicability of UV absorbance at 254 nm (UV 254 ) and volatile fatty acids (VFAs) to serve as reliable surrogates to predict acute toxicity of traditional Chinese medicine (TCM) wastewater was investigated. The medicine residues and VFAs were identified as main components of the TCM wastewater, and their individual and joint toxicity assays were operated with luminescent bacteria. The median effective concentration (EC 50 ) values of medicine residues and VFAs were in the range of 26.46-165.55 mg/L and 11.45-20.58 g/L, respectively. The joint toxicity action modes of medicine residues, VFAs and medicine residues-VFAs were identified as additive, additive and synergistic respectively. UV 254 and VFAs showed better correlations with acute toxicity according to the correlation analysis, compared with other conventional parameters. The regression model was a good fit for toxic unit (TU 50 ) as a function of UV 254 and VFAs according to the stepwise regression method (adjusted R 2  = 0.836). Validation of the model to the pilot-scale samples provided satisfactory prediction results in the influent and hydrolysis acidification effluent samples tests, but for EGSB effluent and final effluent samples, the model needed further optimization. Surrogates prediction using UV 254 and VFAs provided a valuable and cost-saving tool for rapid or on-line monitoring of acute toxicity of TCM wastewater. Copyright © 2017 Elsevier Ltd.

Accumulating epidemiological and clinical evidence shows that inflammation is an important risk factor for various human diseases. Thus, suppressing chronic inflammation has the potential to delay, prevent, and control various chronic diseases, including cerebrovascular, cardiovascular, joint, skin, pulmonary, blood, lymph, liver, pancreatic, and intestinal diseases. Various natural products from traditional Chinese medicine (TCM) have been shown to safely suppress proinflammatory pathways and control inflammation-associated disease. In vivo and/or in vitro studies have demonstrated that anti-inflammatory effects of TCM occur by inhibition of the expression of master transcription factors (for example, nuclear factor-κB (NF-κB)), pro-inflammatory cytokines (for example, tumor necrosis factor-α (TNF-α), chemokines (for example, chemokine (C-C motif) ligand (CCL)-24), intercellular adhesion molecule expression and pro-inflammatory mediators (for example, inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX2)). However, a handful of review articles have focused on the anti-inflammatory activities of TCM and explore their possible mechanisms of action. In this review, we summarize recent research attempting to identify the anti-inflammatory constituents of TCM and their molecular targets that may create new opportunities for innovation in modern pharmacology.

Chaihu-Shu-Gan-San (CSGS), a traditional Chinese medicine (TCM) formula containing seven herbal medicines, has been used in treatment of gastritis, peptic ulcer, irritable bowel syndrome and depression clinically. However, the chemical constituents in CSGS had not been studied so far. To quickly identify the chemical constituents of CSGS and to understand the chemical profiles related to antioxidant activity of CSGS, liquid chromatography coupled with electrospray ionization hybrid linear trap quadrupole orbitrap (LC-LTQ-Orbitrap) mass spectrometry has been applied for online identification of chemical constituents in complex system, meanwhile, antioxidant profile of CSGS was investigated by the fraction collecting and microplate reading system. As a result, 33 chemical constituents in CSGS were identified. Among them, 13 components could be detected both in positive and in negative ion modes, 20 constituents were determined only in positive ion mode and 2 components were only detected in negative ion mode. Meanwhile, the potential antioxidant profile of CSGS was also characterized by combination of 96-well plate collection of elutes from HPLC analysis and microplate spectrophotometer, in which the scavenging activities of free radical produced by DPPH of each fraction could be directly investigated by the analysis of microplate reader. This study quickly screened the contribution of CSGS fractions to the antioxidant activity and online identified the corresponding active constituents. The results indicated that the combination of LC-MS(n) and 96-well plate assay system established in this paper would be a useful strategy for correlating the chemical profile of TCMs with their bioactivities without isolation and purification.

The quality of traditional Chinese medicine (TCM) forms the foundation of its clinical efficacy. The standardization of TCM is the most important task of TCM modernization. In recent years, there has been great progress in the quality control of TCM. However, there are still many issues related to the current quality standards, and it is difficult to objectively evaluate and effectively control the quality of TCM. To face these challenge, we summarized the current quality marker (Q-marker) research based on its characteristics and benefits, and proposed a reasonable and intelligentized quality evaluation strategy for the development and application of Q-markers. Ultra-performance liquid chromatography-quadrupole/time-of-flight with partial least squares-discriminant analysis was suggested to screen the chemical markers from Chinese medicinal materials (CMM), and a bioactive-guided evaluation method was used to select the Q-markers. Near-infrared spectroscopy (NIRS), based on the distinctive wavenumber zones or points from the Q-markers, was developed for its determination. Then, artificial intelligence algorithms were used to clarify the complex relationship between the Q-markers and their integral functions. Internet and mobile communication technology helped us to perform remote analysis and determine the information feedback of test samples. The quality control research, evaluation, standard establishment and quality control of TCM must be based on the systematic analysis of Q-markers to study and describe the material basis of TCM efficacy, define the chemical markers in the plant body, and understand the process of herb drug acquisition, change and transmission laws affecting metabolism and exposure. Based on the advantages of chemometrics, new sensor technologies, including infrared spectroscopy, hyperspectral imaging, chemical imaging, electronic nose and electronic tongue, have become increasingly important in the quality evaluation of CMM. Inspired by the concept of Q-marker, the quantitation can be achieved with the help of artificial intelligence, and these subtle differences can be discovered, allowing the quantitative analysis by NIRS and providing a quick and easy detection method for CMM quality evaluations. The concept of Q-markers focused on unique CMM differences, dynamic changes and their transmission and traceability to establish an overall quality control and traceability system. Based on the basic attributes, an integration model and artificial intelligence research path was proposed, with the hope of providing new ideas and perspectives for the TCM quality management.

To analyze the interdependent relationship between serum bone metabolic markers and traditional Chinese medicine (TCM) syndromes in patients with chronic kidney disease (stages 3 and 4)-related mineral and bone disorder (CKD-MBD), in order to provide the objective basis for exploring the rules of TCM syndrome differentiation in patients with CKD-MBD. The retrospective survey was conducted to collect 105 cases with CKD (stages 3 and 4)-MBD. General clinical indexes, frequency of TCM syndromes and distribution of TCM syndrome type were investigated. Furthermore, serum bone metabolic markers, including calcium (Ca2+), phosphonium (P3+), intact parathyroid hormone (iPTH), alkaline phosphatase (ALP), procollagen type 1 amino-N-terminal propeptide (P1NP) and β-crosslaps (β-CTX) were analyzed, respectively. Meanwhile, bone mineral density (BMD) was assessed. And then, the multivariate regression analysis was performed for serum bone metabolic markers and TCM syndromes. The results showed that the general clinical features of the 105 patients included old age, hypertension, fracture, loss of bone mass and mild abnormalities of serum bone metabolic markers. High-frequency TCM syndromes were related to Yang deficiency in Spleen and Kidney, Qi deficiency in Spleen and Kidney and blood stasis. Moreover, Yang deficiency in Spleen and Kidney and blood stasis were found as the most frequent characteristics of the distribution of TCM syndromes type. The clinical characteristics of patients with the syndrome type of Yang deficiency in Spleen and Kidney were probably old age, increase in TCM syndrome scores and abnormalities in iPTH and P1NP. In addition, the interdependent relationship between abnormality in Ca2+ and syndromes of hair loss, tooth shake and sexual dysfunction, abnormality in P3+ and syndromes of aches in waist and knees, abnormality in iPTH and syndromes of soreness and weakness in waist and knees, lassitude, fatigue and extreme chilliness, abnormality in ALP and syndromes of loose stools, abnormality in P1NP and syndromes of fear of chills, tendency of warmth and loose stools, and abnormality in β-CTX and syndromes of chills and pain in waist and knees. In general, among the 105 cases with CKD (stages 3 and 4)-MBD were clinically characterized by mild changes in serum bone metabolic markers; And their main TCM syndrome was the deficiency in spleen and kidney. Serum bone metabolic markers with mild changes have an interdependent relationship with main TCM syndromes, and can be considered as an objective syndrome factor of TCM syndrome differentiation.

The active ingredients and thus pharmacological efficacy of traditional Chinese medicine (TCM) at different degrees of parching process vary greatly. Near-infrared spectroscopy (NIR) was used to develop a new method for rapid online analysis of TCM parching process, using two kinds of chemical indicators (5-(hydroxymethyl) furfural [5-HMF] content and 420 nm absorbance) as reference values which were obviously observed and changed in most TCM parching process. Three representative TCMs, Areca ( Areca catechu L.), Malt ( Hordeum Vulgare L.), and Hawthorn ( Crataegus pinnatifida Bge.), were used in this study. With partial least squares regression, calibration models of NIR were generated based on two kinds of reference values, i.e. 5-HMF contents measured by high-performance liquid chromatography (HPLC) and 420 nm absorbance measured by ultraviolet-visible spectroscopy (UV/Vis), respectively. In the optimized models for 5-HMF, the root mean square errors of prediction (RMSEP) for Areca, Malt, and Hawthorn was 0.0192, 0.0301, and 0.2600 and correlation coefficients ( R cal ) were 99.86%, 99.88%, and 99.88%, respectively. Moreover, in the optimized models using 420 nm absorbance as reference values, the RMSEP for Areca, Malt, and Hawthorn was 0.0229, 0.0096, and 0.0409 and R cal were 99.69%, 99.81%, and 99.62%, respectively. NIR models with 5-HMF content and 420 nm absorbance as reference values can rapidly and effectively identify three kinds of TCM in different parching processes. This method has great promise to replace current subjective color judgment and time-consuming HPLC or UV/Vis methods and is suitable for rapid online analysis and quality control in TCM industrial manufacturing process. Near-infrared spectroscopy.(NIR) was used to develop a new method for online analysis of traditional Chinese medicine.(TCM) parching processCalibration and validation models of Areca, Malt, and Hawthorn were generated by partial least squares regression using 5.(hydroxymethyl) furfural contents and 420.nm absorbance as reference values, respectively, which were main indicator components during parching process of most TCMThe established NIR models of three TCMs had low root mean square errors of prediction and high correlation coefficientsThe NIR method has great promise for use in TCM industrial manufacturing processes for rapid online analysis and quality control.

This study investigates the constitution of traditional Chinese medicine (TCM) among women who want to be pregnant in one year and explores factors related to TCM constitution. This study was conducted on women who participated in free preconception check-ups provided by the Zhabei District Maternity and Child Care Center in Shanghai, China. The information regarding the female demographic characteristics, physical condition, history of pregnancy and childbearing, diet and behavior, and social psychological factors was collected, and TCM constitution assessment was performed. The Chi-square test, t-test, logistic regression analysis, and multinomial logistic regression analysis were used to explore the related factors of TCM constitution. The participants in this study were aged 28.3 ± 3.0 years. Approximately fifty-five women in this study had Unbalanced Constitution. Logistic regression analysis showed that Shanghai residence, dysmenorrhea, gum bleeding, aversion to vegetables, preference for raw meat, job stress, and economic stress were significantly and negatively associated with Balanced Constitution. Multinomial logistic analysis showed that Shanghai residence was significantly associated with Yang-deficiency, Yin-deficiency, and Stagnant Qi Constitutions; gum bleeding was significantly associated with Yin-deficiency, Stagnant Blood, Stagnant Qi, and Inherited Special Constitutions; aversion to vegetables was significantly associated with Damp-heat Constitution; job stress was significantly associated with Yang-deficiency, Phlegm-dampness, Damp-heat, Stagnant Blood, and Stagnant Qi Constitutions; and economic stress was significantly associated with Yang-deficiency, and Stagnant Qi Constitutions. The application of TCM constitution to preconception care would be beneficial for early identification of potential TCM constitution risks and be beneficial for early intervention (e.g., health education, and dietary education), especially during the women who do not have a medical condition and those who have related factors found in this study.

Summary This dual-site study sought to identify the appropriate role for TCM (acupuncture and herbs) in conjunction with a validated psychosocial self-care intervention (SC) for treating chronic TMD-associated pain. Participants with RDC-TMD-confirmed TMD (n=168) entered a stepped-care protocol that began with a basic TMD class. At weeks 2 and 10, patients receiving SC whose worst facial pain was above predetermined levels were reallocated by minimization to SC or TCM with experienced practitioners. Characteristic facial pain (CFP: mean of worst pain, average pain when having pain, current pain; each VAS 0-10) was the primary outcome. Social activity interference (VAS 0-10) was a secondary outcome. Patients were monitored for safety. TCM provided significantly greater short-term (8-week) relief than SC (CFP reduction difference, −0.60 [SDE 0.26], p=0.020), and greater reduction in interference with social activities (−0.81 [SDE 0.33], p=0.016). In two of five treatment trajectory groups, more than 2/3 of participants demonstrated clinically meaningful responses (> 30% improvement) in pain interference over 16 weeks. This study provides evidence that TMD patients referred for TCM in a community-based model will receive safe treatment that is likely to provide some short-term pain relief and improved quality of life. Similar designs may also apply to evaluations of other kinds of chronic pain. (ClinicalTrials.gov number NCT00856167) PERSPECTIVE This short-term comparative effectiveness study of chronic facial pain suggests that Traditional Chinese Medicine is safe and frequently efficacious alone or subsequent to standard psychosocial interventions. TCM is widely available throughout North America and may provide clinicians and patients with a reasonable addition or alternative to other forms of therapy. PMID:23059454

Previous studies of women with dysmenorrhea have focused on menstrual attitudes, the characteristics of menstrual pain, and self-care behavior. Traditional Chinese Medicine (TCM) studies on dysmenorrhea, on the other hand, have focused on the efficacy and safety of TCM treatments. Few studies have investigated how women perceive their own TCM-treatment experience of dysmenorrhea. The objective of this study was to explore the experience of dysmenorrhea and life adjustments of women undergoing TCM treatment. A semi-structured interviewing guide was used to collect data. A total of 40 dysmenorrheal women participated in the study. Individual, in-depth interviews were conducted for about 60-90 minutes with each participant. Their speech tone, facial expressions, and gestures during the interview process were also observed and recorded. The findings were analyzed using content analysis via ATLAS. ti 5.2 software. The process that the participants used to adjust to dysmenorrhea were distinguished into four progressive stages: "tip of the iceberg", "ice-breaking", "tug-of-war", and "blending-in". Initially, the participants perceived the symptoms of dysmenorrhea as the "tip of the iceberg". They attempted to hide / ignore the initial pain until the problem gradually worsened to the point that the symptoms began to significantly affect various aspects of life. It was only then that the participants began to pay attention to the problem and to seek help from TCM practitioners, which we defined as the "ice-breaking" stage. If they encountered unexpected situations with regard to the treatment regimen, the participants entered the "tug-of-war" stage, during which they struggled over whether to continue with TCM treatments. Afterward, the participants gradually achieved a "blending-in" of new ideas, which allowed them to identify the strategies that best facilitated adjustment and rebalancing. Eventually, the participants achieved a new life balance. The outcomes of the present study may be referenced for nurse-patient communications that relate to dysmenorrhea and TCM treatment.

To investigate the herbal prescription rules of Professor Jiang Liangduo in the treatment of abdominal mass based on the traditional Chinese medicine inheritance support system software (TCMISS) of version 2.5, find out new herbal formulas for the treatment of abdominal mass, and then provide new reference to its traditional Chinese medicine therapy. By the method of retrospective study, one hundred and thirty-two outpatient prescriptions of Professor Jiang for the treatment of abdominal mass were collected to establish a typical database with TCMISS. Four properties, five tastes, channel tropism, frequency count, Chinese herbal prescriptions rules and the new prescriptions were analyzed so as to dig out the prescription rules. There were 57 herbs with a frequency>=15, and then 91 core combinations of 2-5 herbs were evolved and 9 new prescriptions were created. It was found out that these drugs mainly had the effects of liver nourishing and soothing, soft-moist and dredging-tonifying, supporting right and dispeling evil, cooperating with the method of calming the liver and resolving hard lump according to the actual situation. It reflected the thought of treatment based on syndrome differentiation in TCM, and provided a new reference for its clinical treatment and research.

Though cardiovascular diseases (CVDs) and gastrointestinal disorders (GIDs) are different diseases associated with different organs, they are highly correlated clinically. Importantly, in Traditional Chinese Medicine (TCM), similar treatment strategies have been applied in both diseases. However, the etiological mechanisms underlying them remain unclear. Here, an integrated systems pharmacology approach is presented for illustrating the molecular correlations between CVDs and GIDs. Firstly, we identified pairs of genes that are associated with CVDs and GIDs and found that these genes are functionally related. Then, the association between 115 heart meridian (HM) herbs and 163 stomach meridian (SM) herbs and their combination application in Chinese patent medicine was investigated, implying that both CVDs and GIDs can be treated by the same strategy. Exemplified by a classical formula Sanhe Decoration (SHD) treating chronic gastritis, we applied systems-based analysis to introduce a drug-target-pathway-organ network that clarifies mechanisms of different diseases being treated by the same strategy. The results indicate that SHD regulated several pathological processes involved in both CVDs and GIDs. We experimentally confirmed the predictions implied by the effect of SHD for myocardial ischemia. The systems pharmacology suggests a novel integrated strategy for rational drug development for complex associated diseases.

Niuhuang Jiangya Preparation (NHJYP) is one of the most commonly used traditional Chinese patent medicines for essential hypertension (EH) in China. Our meta-analysis performed a systematic evaluation on the therapeutic efficacy and safety of NHJYP for EH. Systematic review and meta-analysis. PubMed, Embase, the Cochrane library, CNKI,VIP, Sinomed, and Wanfang Database were searched up to June 2015. Randomized controlled trials (RCTs) comparing NHJYP or combined with western antihypertensive drugs (WAD) versus WAD were included. Quality of each trial was assessed according to the Cochrane Reviewers' Handbook 5. 1.0. Statistical software (RevMan 5.3) was used for data analysis. The primary outcome was categorical or continuous blood pressure, and the secondary outcome was Traditional Chinese Medicine (TCM) syndrome. 12 RCTs including 1651 cases were identified. The methodological quality of trials was low. Meta-analysis showed that, firstly, NHJYP used alone compared with WAD had no significant effect on BP reduction; however, subgroup analysis was used based on whether apply TCM diagnostic criteria in recruitment. It was suggested that, for population that applied TCM diagnostic criteria, RR=1.35,95% CI:1.17-1.56，P<0.0001; for population that didn't apply TCM diagnostic criteria, RR=0.96,95% CI：0.70-1.33，P=0.81.Reduction in systolic blood pressure (SBP) levels showed similar results. But there was no significant difference in improving diastolic blood pressure (DBP). Secondly, we found that NHJYP plus WAD probably lower BP (RR=1.13，95% CI:1.03-1.24,P=0.01)and improve TCM symptoms than WAD only. And subgroup analysis suggested significant BP reduction effect for population that applied TCM diagnostic. No serious adverse events were reported. Our review indicated that NHJYP has some beneficial effects in EH patients with liver-yang hyperactivity and abundant phlegm-heat syndrome. However, the evidence is not reliable enough. To produce definite evidence, more rigorously designed trials are needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

A comparative study on the traditional Indian Shodhana and Chinese processing methods for aconite roots by characterization and determination of the major components

PubMed Central

2013-01-01

Background Aconitum is an indispensable entity of the traditional medicine therapy in Ayurveda and Traditional Chinese medicine (TCM), in spite of its known fatal toxicity characteristics. The prolonged use of this drug, irrespective of its known lethal effects, is governed by the practice of effective detoxification processes that have been used for decades. However, the processing methods of Ayurveda and TCM are different, and no comparative study has been carried out to evaluate their differences. The objective of the present study was to carry out comparative chemical profiling of the roots of Aconitum heterophyllum Wall, A. carmichaelii Debx., and A. kusnezoffii Reichb. after application of two detoxification methods used in Ayurveda and one method used in TCM . Results Analysis of the processed samples was carried out by ultra-high performance liquid chromatography combined with quadrupole time-of-flight mass spectrometry (UHPLC-QTOF/MS). The results obtained in the study demonstrate that all three processing methods used in Ayurveda and TCM effectively extract the diester diterpenoid alkaloids and led to their conversion into monoester diterpenoid alkaloids. The efficiency of the processes in reduction of toxic alkaloid contents can be stated as: Processing with water > Shodhana with cow milk > Shodhana with cow urine. The analysis method was validated as per ICH-Q2R1 guidelines and all the parameters were found to comply with the recommendations stated in the guidelines. Conclusions There have been no reports till date, to compare the processing methods used in Ayurveda with the methods used in TCM for detoxification of aconite roots. Our study demonstrates that, these methods used in both the traditional systems of medicine, efficiently detoxify the aconite roots. Amongst the three selected procedures, the TCM method of decoction with water is the most efficient. Through experimental evidences, we prove the conversion of toxic diester diterpenoid alkaloids to relatively safer monoester diterpenoid alkaloids. Thus, this study demonstrates that comparative study on the traditional experiences accumulated in different medical systems is useful for expanding their respective applications. PMID:24156713

To systematically review the efficacy and safety of Traditional Chinese Medicine (TCM) interventions, compared with control interventions (placebo or conventional Western medical therapy), in the treatment of acquired immunodeficiency syndrome (AIDS). Electronic databases including PubMed, the Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched to identify relevant randomized controlled trials (RCTs) published as of May 2012. Studies were selected according to the specified inclusion and exclusion criteria and then subjected to methodological quality assessment, data extraction, and meta-analysis according to the Cochrane Handbook for Systematic Reviews of Interventions. Twelve RCTs involving 881 patients with AIDS were included. Methodological quality assessment showed that two were high-quality, two were moderate-quality, and eight were low-quality. Meta-analysis showed that TCM interventions were associated with significantly reduced plasma viral load compared with placebo [odds ratio OR = 2.46, 95% confidence interval CI (1.02, 5.94); P = 0.04]. However, the reductions in plasma viral load significantly favored conventional Western medical therapy alone over integrated traditional Chinese and Western medical therapy [OR = 0.16, 95% CI (0.05, 0.55); P = 0.004]. Patients receiving TCM interventions had significantly higher CD4+ T lymphocyte counts compared with those on placebo [OR = 2.54, 95% CI (1.40, 4.60); P = 0.002]. In addition, TCM interventions were significantly more likely to have improved clinical symptoms [OR = 2.82, 95% CI (1.85, 4.31); P < 0.00001]. TCM interventions conferred a similar risk of adverse events (AEs) compared with control interventions [OR = 1.87, 95% CI (0.58, 6.01); P = 0.29]. Current evidence suggests that TCM interventions are significantly more effective than placebo in reducing plasma viral load and increasing CD4+ T lymphocyte count in patients with AIDS. When compared with conventional Western medical therapy, TCM interventions were significantly less effective in reducing plasma viral load, although they were associated with a higher percentage of patients with improved symptoms. Patients receiving TCM interventions did not seem to be at an increased risk of AEs.

Maintenance therapy for patients with advanced non-small-cell lung cancer (NSCLC) is an increasingly hot topic in the field of clinical NSCLC research. This study aimed to evaluate the effects of Traditional Chinese Medicine (TCM) treatment as maintenance therapy on time to progression (TTP), quality of life (QOL), overall survival (OS) and 1-year survival rate in patients with advanced NSCLC. This study was conducted as a randomized, controlled, open-label trial. 64 non-progressive patients who responded to initial therapy were randomized 1:1 to the TCM arm (treated with herbal injection (Cinobufacini, 20ml/d, d1-d10), herbal decoction (d1-d21) and Chinese acupoint application (d1-d21), n=32) or to the chemotherapy arm (treated with pemetrexed (non-squamous NSCLC, 500mg/m(2), d1), docetaxel (75mg/m(2), d1) or gemcitabine (1250mg/m(2), d1 and d8), n=32). Each therapy cycle was 21 days. They were repeated until disease progression, unacceptable toxicity, or until the patients requested therapy discontinuation. The primary end point was TTP; the secondary end points were QOL, OS and 1-year survival rate. "Intention-to-treat" analysis included all randomized participants. TCM treatment prolonged median TTP for 0.7 months compared with chemotherapy, but it was not statistically significant (3.0 months vs. 2.3 months, P=0.114). Median OS time for TCM treatment did not offer a significant advantage over for chemotherapy (21.5 months vs. 18.8 months, P=0.601). 1-year survival rate of TCM treatment significantly improved than that of chemotherapy (78.1% vs. 53.1%, P=0.035). TCM treatment can significantly improve QOL when compared to chemotherapy as assessed by EORTC QLQ-C30 and EORTC QLQ-LC13 QOL instruments. TCM maintenance treatment had similar effects on TTP and OS compared with maintenance chemotherapy, but it improved patients' QOL and had higher 1-year survival rate. TCM Maintenance treatment is a promising option for advanced NSCLC patients without progression following first-line chemotherapy. Copyright © 2015 Elsevier Ltd. All rights reserved.

Objective. To evaluate the effectiveness of external application of traditional Chinese medicine (EA-TCM) on venous ulcers. Methods. Seven databases were searched until April 2015 for randomized controlled trials (RCTs) of EA-TCM for venous ulcers. Risk of bias was assessed using Cochrane Handbook guidelines. Study outcomes were presented as risk ratios (RRs) for dichotomous data or mean differences (MDs) for continuous data. Results. Sixteen of 193 potentially relevant trials met the inclusion criteria; however, their methodological qualities were low. Comparison of the same intervention strategies revealed significant differences in total effectiveness rates between EA-TCM and conventional therapy groups (RR = 1.22, 95% confidence interval [CI] = 1.16–1.29, and P < 0.00001). Compared to conventional therapy, EA-TCM combined with conventional therapy had a superior total effectiveness rate (RR = 1.11, 95% CI = 1.04–1.19, and P = 0.003). There were no significant differences in recurrence rates during followup and final pain measurements between the experimental and those in the control groups (RR = 0.86, 95% CI = 0.31–2.39, and P = 0.85; MD −0.75, 95% CI = −2.15–0.65, and P = 0.29). Conclusion. The evidence that EA-TCM is an effective treatment for venous ulcers is encouraging, but not conclusive due to the low methodological quality of the RCTs. Therefore, more high-quality RCTs with larger sample sizes are required. PMID:26435725

Traditional Chinese Medicine and Herb-induced Liver Injury: Comparison with Drug-induced Liver Injury

PubMed Central

Jing, Jing; Teschke, Rolf

2017-01-01

Abstract Cases of suspected herb-induced liver injury (HILI) caused by herbal Traditional Chinese Medicines (TCMs) and of drug-induced liver injury (DILI) are commonly published in the scientific literature worldwide. As opposed to the multiplicity of botanical chemicals in herbal TCM products, which are often mixtures of several herbs, conventional Western drugs contain only a single synthetic chemical. It is therefore of interest to study how HILI by TCM and DILI compare with each other, and to what extent results from each liver injury type can be transferred to the other. China is among the few countries with a large population using synthetic Western drugs as well as herbal TCM. Therefore, China is well suited to studies of liver injury comparing drugs with TCM herbs. Despite some concordance, recent analyses of liver injury cases with verified causality, using the Roussel Uclaf Causality Assessment Method, revealed major differences in HILI caused by TCMs as compared to DILI with respect to the following features: HILI cases are less frequently observed as compared to DILI, have a smaller proportion of females and less unintentional rechallenge events, and present a higher rate of hepatocellular injury features. Since many results were obtained among Chinese residents who had access to and had used Western drugs and TCM herbs, such ethnic homogeneity supports the contention that the observed differences of HILI and DILI in the assessed population are well founded.

We explored the correlates of use of TCM and WM by ethnic Chinese students in the UK. A questionnaire assessed key theoretical determinants of health services use. One hundred and seventy ethnic Chinese participants (international students at one university in the South of England) completed this questionnaire (presented in English and Chinese) assessing their demographic characteristics, health status, attitudes towards and use of TCM and WM. Participants were more likely to use WM than TCM when they were in the UK. Different variables predicted use of WM and TCM. The statistical predictors (demographic characteristics, health status, past behaviour, attitudes) explained modest but important proportions of the variance in use of WM (37%) and TCM (29%). In conclusion, this small exploratory study suggests a need for further research on the health care utilisation of this growing body of international students. Improved language support is needed for international students in UK health care settings.

During the period of the Republic of China, researches of experiments on Chinese materia medica developed extensively with the scientific process of Chinese medicine. Although the technology standard was relatively low and the reference value, limited. The experiences, positive or negative, obtained at that time still has reference significance to today's Chinese medicine scientific research. The notion that traditional Chinese medical and scientific research be conducted under the guidance of TCM theory; valuable experience contained in the ancient literature of traditional Chinese medicine be collected; and the transformation capacity of scientific research be elevated, has been accepted by modern TCM professionals. If you go back to the history, it can be seen that this notion was summarized through repeated practice during the critical moment of traditional Chinese medicine, which should be emphasized and its understanding deepened at any time.

2006-06-01

Angiogenesis is a major pathological component of diseases such as cancer and coronary heart disease. Although major advances have been made and encouraging clinical results obtained, safer and more effective approaches are required. The identification of new drugs from plants has a long and successful history, and certain proangiogenic and antiangiogenic plant components have been used in traditional Chinese medicine (TCM) for thousands of years. Similar to Western combination therapy, TCM uses mixtures of plant extracts, termed fufang, to maximize efficacy and minimize adverse effects or toxicity. More evidence-based research and chemical optimization of these compounds could further enhance the effectiveness of these plant-based medicines in angiotherapy.

Bibliometric Analysis of Traditional Chinese Medicine Scientific Production between 1982 and 2016 Indexed in PubMed.

PubMed

Consentino, Ricardo; Santos, Maria João; Matos, Luís Carlos; Machado, Jorge Pereira

2018-05-03

Background: Traditional Chinese medicine (TCM) may be understood as a system of sensations and findings designed to establish the functional vegetative state of the body. This state may be treated by several therapeutic methods such as acupuncture, Chinese pharmacotherapy, dietetics, Tuina , and Qigong . Nowadays, as a result of several evidence-based reported beneficial effects over specific pathological conditions, there is an increasing tendency to integrate some of these practices in Western medicine. The main goal of this study was to perform a bibliometric analysis of TCM scientific production between 1982 and 2016 indexed in PubMed, by analyzing several parameters including time and location distribution, publication quality, experimental design, and treatment methods. Methods: The methodology was based on the quantitative inventory of published scientific research indexed in PubMed medical subject headings (MeSH), sorted within the broad term “Traditional Chinese Medicine” and integrating the following criteria as limit filters: “Species: Humans”, “Article Type: Clinical Trial”. In addition, the articles’ triage was ruled by temporal limitations set between 1945 and 2016. Results: The overall analysis of data allowed observation of an average annual growth of approximately 33%, with a productive peak of 122 articles in 2007. The scientific production was distributed in 27 countries, led by China (76.1%), followed by the United States of America (3.0%) and South Korea (2.1%). A significant amount of references were published in Chinese journals: more than 50%; however, these journals had a low impact factor. The most cited treatments in the keywords section of the articles were phytotherapy (55%) and acupuncture (40%). Conclusion: The increasing demand for TCM seems to be due to factors such as lower side effects and greater efficacy in some patients not responding well to conventional therapy. As a result, a considerable amount of TCM science-based literature has been produced, supporting the rational integration of these practices in Western healthcare systems and research. Our results show that the quality of TCM research and inherent publications have been increasing over the last decades, with a higher incidence of studies published in well-ranked journals.

[Similarity system theory to evaluate similarity of chromatographic fingerprints of traditional Chinese medicine].

PubMed

Liu, Yongsuo; Meng, Qinghua; Jiang, Shumin; Hu, Yuzhu

2005-03-01

The similarity evaluation of the fingerprints is one of the most important problems in the quality control of the traditional Chinese medicine (TCM). Similarity measures used to evaluate the similarity of the common peaks in the chromatogram of TCM have been discussed. Comparative studies were carried out among correlation coefficient, cosine of the angle and an improved extent similarity method using simulated data and experimental data. Correlation coefficient and cosine of the angle are not sensitive to the differences of the data set. They are still not sensitive to the differences of the data even after normalization. According to the similarity system theory, an improved extent similarity method was proposed. The improved extent similarity is more sensitive to the differences of the data sets than correlation coefficient and cosine of the angle. And the character of the data sets needs not to be changed compared with log-transformation. The improved extent similarity can be used to evaluate the similarity of the chromatographic fingerprints of TCM.

A TCMIs safety monitoring team and a research hospital team engaged in the research, monitoring processes, and quality control processes were established, in order to achieve comprehensive, timely, accurate and real-time access to research data, to eliminate errors in data collection. A triage system involving a study nurse, as the first point of contact, clinicians and clinical pharmacists was set up in a TCM hospital. Following the specified workflow involving labeling of TCM injections and using improved monitoring forms it was found that there were no missing reports at the ratio of error was zero. A research nurse as the first and main point of contact in post-marketing safety monitoring of TCM as part of a triage model, ensures that research data collected has the characteristics of authenticity, accuracy, timeliness, integrity, and eliminate errors during the process of data collection. Hospital based monitoring is a robust and operable process.

Pancreatic triacylglycerol lipase (PNLIP) are primary lipases that are critical for triacylglyceride digestion in human. Since reduced metabolism of triacylglyceride might be a plausible concept for weight loss, we screened for potential PNLIP inhibitors from traditional Chinese medicine (TCM) with the aim to identify weight loss candidate compounds. TCM candidates Aurantiamide, Cnidiadin, and 2-hexadecenoic acid exhibited higher Dock Scores than the commercial drug Orlistat, and were also predicted to have inhibitory characteristics against PNLIP using constructed MLR (R(2) = 0.8664) and SVM (R(2) = 0.9030) models. Molecular dynamics indicated that the TCM-PNLIP complexes formed were stable. We identified that the PNLIP binding site has several residues that can serve as anchors, and a hydrophobic corridor that provides additional stability to the complex. Aurantiamide, Cnidiadin, and 2-hexadecenoic acid all have features that correspond to these binding site features, indicating their potential as candidates for PNLIP inhibitors. The information presented in this study may provide helpful insights to designing novel weight-control drugs.

We investigated the usage of secondary prevention drugs and traditional Chinese medicine (TCM) products in individuals with cardiovascular diseases (CVDs) at the community level in China. Among 2,407 participants with self-reported coronary heart disease (CHD) and 872 with stroke, nearly 80% of individuals with CHD and 73% of individuals with stroke were not taking any proven secondary prevention drug. However, 32.9% of them took TCM products. Patients with CVDs in rural areas used less secondary prevention treatment, but more TCM products than their counterparts in the urban regions. After adjusting for confounding factors, lower rates of secondary prevention treatment were evident in Western China compared with Eastern China, which was more developed. Systematic change is needed to promote the development of evidence-based medicine at the community level in China. Copyright © 2017 The Editorial Board of Biomedical and Environmental Sciences.

The research of new herbal drugs involves in new herbal drugs development and renew the old drugs. It is necessary to research new herbal drugs based on the theory of traditional Chinese medicine (TCM). The current development of famous TCM focuses on the manufacture process, quality control standards, material basis and clinical research. But system management of security evaluation is deficient, the relevant system for the safety assessment TCM has not been established. The causes of security problems, security risks, target organ of toxicity, weak link of safety evaluation, and ideas of safety evaluation are discussed in this paper. The toxicology research of chinese herbal drugs is necessary based on standard of good laboratory practices (GLP), the characteristic of Chinese herbal drugs is necessary to be fully integrated into safety evaluation. The safety of new drug research is necessary to be integrated throughout the entire process. Famous Chinese medicine safety research must be paid more attention in the future.

Background: Herbal medicine is widely used all over the world for treating various health disorders. It is employed either alone or in combination with synthetic drugs or plants to be more effective. Objective: The assessment of the effect of both water and methanol extracts of 57 widely used plants from Traditional Chinese Medicine (TCM) against the main phase I metabolizing enzyme CYP3A4 in vitro for the first time. Materials and Methods: The inhibition of cytochrome P450 activity was evaluated using a luminescence assay. The principal component analysis (PCA) was used to correlate the inhibitory activity with the main secondary metabolites present in the plant extracts. Molecular modeling studies on CYP3A4 (PDB ID 4NY4) were carried out with 38 major compounds present in the most active plant extracts to validate the observed inhibitory effect. Results: Aqueous extracts of Acacia catechu, Andrographis paniculata, Arctium lappa, Areca catechu, Bupleurum marginatum, Chrysanthemum indicum, Dysosma versipellis, and Spatholobus suberectus inhibited CYP3A4 is more than 85% (at a dose of 100 μg/mL). The corresponding methanol extracts of A. catechu, A. paniculata, A. catechu, Mahonia bealei, and Sanguisorba officinalis inhibited the enzyme by more than 50%. Molecular modeling studies revealed that two polyphenols, namely hesperidin and rutin, revealed the highest fitting scores in the active sites of the CYP3A4 with binding energies equal to -74.09 and -71.34 kcal/mol, respectively. Conclusion: These results provide evidence that many TCM plants can inhibit CYP3A4, which might cause a potential interference with the metabolism of other concomitantly administered herbs or drugs. SUMMARY In this study, the inhibitory activity of the aqueous and methanol extracts of 57 widely used plants from Traditional Chinese Medicine (TCM) against the main phase I metabolizing enzyme CYP3A4 was tested in vitro for the first time.Aqueous extracts of Acacia catechu, Andrographis paniculata, Arctium lappa, Areca catechu, Bupleurum marginatum, Dysosma versipellis, and Spatholobus suberectus inhibited CYP3A4 by more than 85% (at a dose of 100 μg/mL).The activity could be attributed to the presence of polyphenolics as revealed from the multivariate chemometric analysis and molecular modeling study.These results provide evidence that many TCM plants can inhibit CYP3A4, which might cause a potential interference with the metabolism of other concomitantly administered herbs or drugs.

This paper shall first investigate the informatics areas and applications of the four Traditional Medicine systems - Traditional Chinese Medicine (TCM), Ayurveda, Traditional Arabic and Islamic Medicine and Traditional Malay Medicine. Then, this paper shall examine the national informatics infrastructure initiatives in the four respective countries that support the Traditional Medicine systems. Challenges of implementing informatics in Traditional Medicine Systems shall also be discussed. The literature was sourced from four databases: Ebsco Host, IEEE Explore, Proquest and Google scholar. The search term used was "Traditional Medicine", "informatics", "informatics infrastructure", "traditional Chinese medicine", "Ayurveda", "traditional Arabic and Islamic medicine", and "traditional malay medicine". A combination of the search terms above was also executed to enhance the searching process. A search was also conducted in Google to identify miscellaneous books, publications, and organization websites using the same terms. Amongst major advancements in TCM and Ayurveda are bioinformatics, development of Traditional Medicine databases for decision system support, data mining and image processing. Traditional Chinese Medicine differentiates itself from other Traditional Medicine systems with documented ISO Standards to support the standardization of TCM. Informatics applications in Traditional Arabic and Islamic Medicine are mostly ehealth applications that focus more on spiritual healing, Islamic obligations and prophetic traditions. Literature regarding development of health informatics to support Traditional Malay Medicine is still insufficient. Major informatics infrastructure that is common in China and India are automated insurance payment systems for Traditional Medicine treatment. National informatics infrastructure in Middle East and Malaysia mainly cater for modern medicine. Other infrastructure such as telemedicine and hospital information systems focus its implementation in modern medicine or are not implemented and strategized at a national level to support Traditional Medicine. Informatics may not be able to address all the emerging areas of Traditional Medicine because the concepts in Traditional Medicine system of medicine are different from modern system, though the aim may be same, i.e., to give relief to the patient. Thus, there is a need to synthesize Traditional Medicine systems and informatics with involvements from modern system of medicine. Future research works may include filling the gaps of informatics areas and integrate national informatics infrastructure with established Traditional Medicine systems.

Efficacy and safety assessments are essential thresholds for drug candidates from preclinical to clinical research. Conventional mammalian in vivo models cannot offer rapid pharmacological and toxicological screening, whereas cell-based or cell-free in vitro systems often lead to inaccurate results because of the lack of physiological environment. Within the avian species, gallus gallus is the first bird to have its genome sequencing. Meantime, chick embryo is an easily operating, relatively transparent and extensively accessible model, whose physiological and pathological alterations can be visualized by egg candler, staining and image technologies. These features facilitate chick embryo as a high-throughput screening platform bridging in vivo and in vitro gaps in the pharmaceutical research. Due to the complicated ingredients and multiple-targets natures of traditional Chinese medicine (TCM), testing the efficacy and safety of TCM by in vitro methods are laborious and inaccurate, while testing in mammalian models consume massive cost and time. As such, the productive living organism chick embryo serves as an ideal biological system for pharmacodynamics studies of TCM. Herein, we comprehensively update recent progresses on the specialty of chick embryo in evaluation of efficacy and toxicity of drugs, with special concerns of TCM. Copyright © 2018 Elsevier Ltd.

Background: The shift in age structure is having a profound impact, suggesting that the aged should be consulted as reporters on the quality of their own lives. Objectives: The aim of this research was to establish the possible impact of traditional Chinese medicine (TCM) techniques on the quality of life (QOL) of the elderly. Sample: Two non-selected, volunteer groups of Rio de Janeiro municipality inhabitants: a control group (36 individuals), not using TCM, and an experimental group (28 individuals), using TCM at ABACO/Sohaku-in Institute, Brazil. Methods: A questionnaire on elderly QOL devised by the World Health Organization, the WHOQOL-Old, was adopted and descriptive statistical techniques were used: mean and standard deviation. The Shapiro–Wilk test checked the normality of the distribution. Furthermore, based on its normality distribution for the intergroup comparison, the Student t test was applied to facets 2, 4, 5, 6, and total score, and the Mann–Whitney U rank test to facets 1 and 3, both tests aiming to analyze the P value between experimental and control groups. The significance level utilized was 95% (P < 0.05). Results: The experimental group reported the highest QOL for every facet and the total score. Conclusions: The results suggest that TCM raises the level of QOL. PMID:21103400

There is a constant demand to develop new, effective, and affordable anti-cancer drugs. The traditional Chinese medicine (TCM) is a valuable and alternative resource for identifying novel anti-cancer agents. In this study, we aim to identify the anti-cancer compounds and plants from the TCM database by using cheminformatics. We first predicted 5278 anti-cancer compounds from TCM database. The top 346 compounds were highly potent active in the 60 cell lines test. Similarity analysis revealed that 75% of the 5278 compounds are highly similar to the approved anti-cancer drugs. Based on the predicted anti-cancer compounds, we identified 57 anti-cancer plants by activity enrichment. The identified plants are widely distributed in 46 genera and 28 families, which broadens the scope of the anti-cancer drug screening. Finally, we constructed a network of predicted anti-cancer plants and approved drugs based on the above results. The network highlighted the supportive role of the predicted plant in the development of anti-cancer drug and suggested different molecular anti-cancer mechanisms of the plants. Our study suggests that the predicted compounds and plants from TCM database offer an attractive starting point and a broader scope to mine for potential anti-cancer agents.

To reevaluate the systematic reviews for traditional Chinese medicine(TCM) injections for treating coronary disease, data in four Chinese databases and PubMed, Embase, Cochrane Library, Wed of Science OVID from inception until May 2016 were searched. We extracted data according to the AMSTAR and PRISMA checklists to evaluate the methodological quality and reporting characteristics of included literatures. A total of 69 systematic reviews were included, involving 24 TCM injections, which showed certain efficacy in treating coronary disease, and whose main outcome indexes included alleviation of symptoms of angina pectoris and electrocardiogram. In all of the systematic reviews, the duration of follow-up were not reported. Six systematic reviews reported TCM typing. In the 44 system reviews, 1 335 reports mentioned 4 137 adverse events. According to the results of AMSTAR and PRISMA checklists, the quality assessment scores about included studies were not high, and most of the systematic reviews suffered heterogeneity and irrational processing of forest plots. In conclusion, TCM injections in the treatment of coronary disease have a wide range and positive effects. However, affected by the low quality of systematic reviews and the production of reevaluation, the study had some limitations. Therefore, the systematic reviews shall be further improved, in order to provide more advanced clinical evidences to clinicians. Copyright© by the Chinese Pharmaceutical Association.

The paper aimed to screen out genetic markers applicable to early diagnosis for colorectal cancer and establish apoptotic regulatory network model for colorectal cancer, and to analyze the current situation of traditional Chinese medicine (TCM) target, thereby providing theoretical evidence for early diagnosis and targeted therapy of colorectal cancer. Taking databases including CNKI, VIP, Wanfang data, Pub Med, and MEDLINE as main sources of literature retrieval, literatures associated with genetic markers that are applied to early diagnosis of colorectal cancer were searched and performed comprehensive and quantitative analysis by Meta analysis, hence screening genetic markers used in early diagnosis of colorectal cancer. KEGG analysis was employed to establish apoptotic regulatory network model based on screened genetic markers, and optimization was conducted on TCM targets. Through Meta analysis, seven genetic markers were screened out, including WWOX, K-ras, COX-2, P53, APC, DCC and PTEN, among which DCC has the highest diagnostic efficiency. Apoptotic regulatory network was built by KEGG analysis. Currently, it was reported that TCM has regulatory function on gene locus in apoptotic regulatory network. The apoptotic regulatory model of colorectal cancer established in this study provides theoretical evidence for early diagnosis and TCM targeted therapy of colorectal cancer in clinic.

Chinese marine materia medica (CMMM) is a vital part of traditional Chinese medicine (TCM). Compared with terrestrial TCM, CMMM, derived from specific marine habitats, possesses peculiar chemical components with unique structures reflecting as potent pharmacological activities, distinct drug properties and functions. Nowadays, CMMM appears to be especially effective in treating such difficult diseases as cancers, diabetes, cardio-cerebrovascular diseases, immunodeficiency diseases and senile dementia, and therefore has become an important medicinal resource for the research and development of new drugs. In recent years, such development has attracted wide attention in the field of medicine. In this study, the CMMM resources in China were systematically investigated and evaluated. It was found that the historic experiences of Chinese people using CMMM have continuously accumulated over a period of more than 3600 years, and that the achievements of the research on modern CMMM are especially outstanding. By June 2015, 725 kinds of CMMMs from Chinese coastal sea areas have been identified and recorded, covering 1552 organisms and minerals. More than 3100 traditional prescriptions containing CMMMs have been imparted and inherited. However, the number of CMMMs is less than the 8188 terrestrial TCMs, from more than 12,100 medicinal terrestrial plants, animals and minerals. In the future, the research and development of CMMM should focus on the channel entries (TCM drug properties), compatibility, effective ingredients, acting mechanisms, drug metabolism and quality standard. This study reveals the high potential of CMMM development. PMID:26950133

The Acupuncture-moxibustion and Acupuncture-moxibustion therapy have been the state-compiled textbooks of acupuncture-moxibustion in colleges and universities of TCM for nearly more than half a century, which play a regulating and guiding role for acupuncture education and to a certain extent represent the development status of this discipline. The indications included in Acupuncture-moxibustion from 1th edition to 7th edition and Acupuncture-moxibustion therapy from 1th edition to 3rd edition were analyzed in this study, which was aimed to basically reflect the current situation of acupuncture indications. As a result, it was found the inheritance and innovation of indications were both reflected in each edition of textbooks, 1/3 of which occurred repeatedly in more than half of the textbooks, and 1/3 of which occurred only once. The indications were classified by internal medicine, surgery, gynecology, dermatology, orthopedics, etc., which were not consistent with system classification of modern medicine such as digestive system, respiratory system, etc. The indications were mainly named after TCM disease names, involving only several names of western medicine diseases, which were contradicted to the names adopted from journals and literature. This inconformity of classification method and naming method between TCM and western medicine was not only a difficulty for modern acupuncture and moxibustion, but also an essential factor to hinder the development of acupuncture, therefore comparative study was needed in the future.

2016-01-01

Cancer-related anorexia syndrome (CACS) is one of the main causes for death at present as well as a syndrome seriously harming patients' quality of life, treatment effect and survival time. In current clinical researches, there are fewer reports about empirical traditional Chinese medicine(TCM) prescriptions and patent prescriptions treating CACS, and prescription rules are rarely analyzed in a systematic manner. As the hidden rules are not excavated, it is hard to have an innovative discovery and knowledge of clinical medication. In this paper, the grey screening method combined with the multivariate statistical method was used to build the ″CACS prescriptions database″. Based on the database, totally 359 prescriptions were selected, the frequency of herbs in prescription was determined, and commonly combined drugs were evolved into 4 new prescriptions for different syndromes. Prescriptions of TCM in treatment of CACS gave priority to benefiting qi for strengthening spleen, also laid emphasis on replenishing kidney essence, dispersing stagnated liver-qi and dispersing lung-qi. Moreover, interdependence and mutual promotion of yin and yang should be taken into account to reflect TCM's holism and theory for treatment based on syndrome differentiation. The grey screening method, as a valuable traditional Chinese medicine research-supporting method, can be used to subjectively and objectively analyze prescription rules; and the new prescriptions can provide reference for the clinical use of TCM for treating CACS and the drug development.

Innovating Chinese Herbal Medicine: From Traditional Health Practice to Scientific Drug Discovery.

PubMed

Gu, Shuo; Pei, Jianfeng

2017-01-01

As one of the major contemporary alternative medicines, traditional Chinese medicine (TCM) continues its influence in Chinese communities and has begun to attract the academic attention in the world of western medicine. This paper aims to examine Chinese herbal medicine (CHM), the essential branch of TCM, from both narrative and scientific perspectives. CHM is a traditional health practice originated from Chinese philosophy and religion, holding the belief of holism and balance in the body. With the development of orthodox medicine and science during the last centuries, CHM also seized the opportunity to change from traditional health practice to scientific drug discovery illustrated in the famous story of the herb-derived drug artemisinin. However, hindered by its culture and founding principles, CHM faces the questions of the research paradigm posed by the convention of science. To address these questions, we discussed two essential questions concerning the relationship of CHM and science, and then upheld the paradigm of methodological reductionism in scientific research. Finally, the contemporary narrative of CHM in the 21st century was discussed in the hope to preserve this medical tradition in tandem with scientific research.

Oligoasthenozoospermia is a crucial factor in male infertility. Wuzi Yanzong (WZYZ) pill is a popular traditional Chinese medicine (TCM) formula which has been used for male infertility treatment for years. However, its effects on semen quality remain controversial. We conducted a preregistered meta-analysis to assess the effect of WZYZ pill for the therapeutic effects on oligoasthenozoospermia. Five randomized controlled trials including 960 participants were selected from databases of domains in North-East Asian regions, PubMed, Embase, and Cochrane Library. WZYZ pill group yielded a greater mean increment on sperm concentration (5 trials: MD 5.99, 95% CI 2.12–9.85, P = 0.002), sperm motility (5 trials: MD 4.57, 95% CI 0.47–8.68, P = 0.03), sperm morphology (2 trials: MD −1.93, 95% CI −4.87–1.01, P = 0.20), activity of acrosomal enzyme (2 trials: MD 28.27, 95% CI 12.41–44.14, P < 0.01), volume of semen (2 trials: MD 0.56, 95% CI 0.21–0.91, P = 0.002), and a decrement of sperm DNA fragmentation index (2 trials: MD −3.82, 95% CI −6.45–−1.19, P = 0.004). However, qualities of selected studies were generally unsatisfactory, and there was inherent heterogeneity among some of the outcomes. Despite these limitations, the WZYZ pill improved sperm quality by improving several semen parameters and decreasing DNA damage in oligoasthenozoospermia patients. PMID:29576794

Purpose We aimed to quantify Chinese cancer survivors’ perceived needs for survivorship care and to evaluate whether these needs could impact their willingness to use traditional Chinese medicine (TCM). Methods We conducted a cross-sectional survey with members of the Beijing Anti-Cancer Association in China. We measured perceived needs with the seven-item Brief Chinese Cancer Survivorship Needs Scale that assesses psychological, functional, nutritional, social, body image, pain, and symptom needs. The outcome variable was willingness to use TCM for survivorship care. We performed multivariable logistic regression analyses to evaluate whether perceived needs are associated with willingness. Results A total of 600 patients were invited, with a response rate of 81%. The mean (standard deviation) score of the perceived needs scale (0 to 10) was 4.4 (2.2), with the majority of participants endorsing nutritional (72%), symptom (65%), and psychological (54%) needs. Among survivors, 387 (80%; 95% CI, 76% to 83%) were willing to use TCM for survivorship care. In multivariable analysis, a higher perceived needs score (adjusted odds ratio [OR], 1.33; 95% CI, 1.14 to 1.56; P < .001) was associated with greater willingness to use TCM. Specifically, nutritional (OR, 3.17; 95% CI, 1.79 to 5.62; P < .001) and symptom needs (OR, 3.15; 95% CI, 1.79 to 5.55; P < .001) had the strongest relationship. Conclusion A higher level of perceived needs, especially in the areas of nutrition and symptoms, was associated with greater willingness to use TCM for survivorship care. PMID:29244994

The objective of this article is to describe and compare the use of traditional/complementary medicine (T/CM) among psychotic (schizophrenia and schizophreniform disorder) and epileptic Malay patients in peninsular Malaysia. There were 60 patients in each group. T/CM consultation was uniformly spread across all levels of education and social status. We could not find a single over-riding factor that influenced the decision to seek T/CM treatment because the decision to seek such treatment was complex and the majority of decisions were made by others. Fifty-three patients (44.2%), consisting of 37 (61.7%) psychotic and 16 (26.7%) epileptic patients had consulted Malay traditional healers (bomoh) and/or homeopathic practitioners in addition to modern treatment; of these, only three had consulted bomoh and homeopathic practitioners at the same time. The use of T/CM was significantly higher in psychotic than in epileptic Malay patients.

As traditional Chinese medicine (TCM) preparation products feature complex compounds and multiple preparation processes, the implementation of quality control in line with the characteristics of TCM preparation products provides a firm guarantee for the clinical efficacy and safety of TCM preparation products. Danshen infusion solution is a preparation commonly used in clinic, but its quality control is restricted to indexes of finished products, which can not guarantee its inherent quality. Our study group has proposed "multi-dimensional structure and process dynamics quality control system" on the basis of "component structure theory", for the purpose of controlling the quality of Danshen infusion solution at multiple levels and in multiple links from the efficacy-related material basis, the safety-related material basis, the characteristics of dosage form to the preparation process. This article, we bring forth new ideas and models to the quality control of TCM preparation products.

MaiMenDong Decoction and WeiJing Decoction (Jin formula) is a traditional Chinese medication that consists of 8 medicinal plants, which recorded in the classical TCM literature Jin Kui Yao Lue and has been utilized in the treatment of lung diseases for hundreds of years in China. The present study aimed to determine the anti-tumor activity and the underlying mechanisms of Jin formula combined with cisplatin in the treatment of non-small cell lung cancer (NSCLC). Xenograft model of NCI-A549 was established in Balb/c nude mice. Five groups, including normal, MOCK, Jin, cisplatin (DDP), and Jin+DDP were included in the study. We found that Jin formula ameliorated the body weight loss caused by DDP 15 days after drug administration. Moreover, the combination of Jin with DDP enhanced the anti-tumor function of DDP. Microarray analysis showed that Jin suppressed gene expression of certain pathways which regulating cell cycle and apoptosis. Furthermore, DDP mainly decreased the gene expression level of angiogenesis associated factors, such as VEGFA, TGF-β and MMP-1. Moreover, co-treatment with Jin and DDP not only down-regulated Bcl-2 and E2F1, but also decreased the expression of MYC, MET, and MCAM. In addition, co-formula decreased the levels of p-AKT (thr308) and p-PTEN, increased Bax/Bcl-2 value, and resulted in apoptosis of tumor cells. Taken together , Jin+DDP significantly inhibited the growth of A549 cell transplanted solid tumor with slight side effect compared to the treatment by DDP only, and had a better effect than the Jin group. The mechanisms may be mainly associated with inactivation of PI3K/AKT pathway and apoptosis induction.

Community-acquired pneumonia in children is common in China. To understand current clinical characteristics and practice, we conducted a cross-sectional study to analyze quality of care on childhood pneumonia in eight eastern cities in China. Consecutive hospital records between January 1, 2010 and December 31, 2010 were collected from 13 traditional Chinese medicine (TCM) and western medicine (WM) hospitals in February, May, August, and November (25 cases per season, 100 cases over the year), respectively. A predesigned case report form was used to extract data from the hospital medical records. A total of 1298 cases were collected and analyzed. Symptoms and signs upon admission at TCM and WM hospitals were cough (99.3% vs. 98.6%), rales (84.8% vs. 75.0%), phlegm (83.3% vs. 49.1%), and fever (74.9% vs. 84.0%) in frequency. Patients admitted to WM hospitals had symptoms and signs for a longer period prior to admission than patients admitted to TCM hospitals. Testing to identify etiologic agents was performed in 1140 cases (88.4%). Intravenous antibiotics were administered in 99.3% (595/598) of cases in TCM hospitals and in 98.6% (699/700) of cases in WM hospitals. Besides, Chinese herbal extract injection was used more frequently in TCM hospitals (491 cases, 82.1%) than in WM hospitals (212 cases, 30.3%) (p < 0.01). At discharge, 818 cases (63.0%) were clinically cured, with a significant difference between the cure rates in TCM (87.6%) and WM hospitals (42.0%) (OR = 9.8, 95% confidence interval (CI): 7.3 ~ 12.9, p < 0.01). Pathogen and previous medical history were more likely associated with the disappearance of rales (OR = 7.2, 95% CI: 4.8 ~ 10.9). Adverse effects were not reported from the medical records. Intravenous use of antibiotics is highly prevalent in children with community-acquired pneumonia regardless of aetiology. There was difference between TCM and WM hospitals with regard to symptom profile and the use of antibiotics. Intravenous use of herbal injection was higher in TCM hospitals than in WM hospitals. Most of the cases were diagnosed based on clinical signs and symptoms without sufficient confirmation of aetiology. Audit of current practice is urgently needed to improve care.

Traditional Chinese Medicine Induced Liver Injury

Traditional Chinese Medicine (TCM) is popular around the world and encompasses many different practices with particular emphasis on herbal TCM. Using the PubMed database, a literature search was undertaken to assess the extent herbal TCM products exert rare hepatotoxicity. Analysis of reported cases revealed numerous specified herbal TCM products with potential hepatotoxicity. Among these were An Shu Ling, Bai Fang, Bai Xian Pi, Ban Tu Wan, Bo He, Bo Ye Qing Niu Dan, Bofu Tsu Sho San, Boh Gol Zhee, Cang Er Zi, Chai Hu, Chaso, Chi R Yun, Chuan Lian Zi, Ci Wu Jia, Da Chai Hu Tang, Da Huang, Du Huo, Gan Cao, Ge Gen, Ho Shou Wu, Hu Bohe You, Hu Zhang, Huang Qin, Huang Yao Zi, Hwang Geun Cho, Ji Gu Cao, Ji Ji, Ji Xue Cao, Jiguja, Jin Bu Huan, Jue Ming Zi, Kamishoyosan, Kudzu, Lei Gong Teng, Long Dan Xie Gan Tang, Lu Cha, Ma Huang, Mao Guo Tian Jie Cai, Onshido, Polygonum multiflorum, Qian Li Guang, Ren Shen, Sairei To, Shan Chi, Shen Min, Shi Can, Shi Liu Pi, Shou Wu Pian, Tian Hua Fen, White flood, Wu Bei Zi, Xi Shu, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, Zhen Chu Cao, and various unclassified Chinese herbal mixtures. Causality was firmly established for a number of herbal TCM products by a positive reexposure test result, the liver specific scale of CIOMS (Council for International Organizations of Medical Sciences), or both. Otherwise, the quality of case data was mixed, especially regarding analysis of the herb ingredients because of adulteration with synthetic drugs, contamination with heavy metals, and misidentification. In addition, non-herbal TCM elements derived from Agaricus blazei, Agkistrodon, Antelope, Bombyx, Carp, Fish gallbladder, Phellinus, Scolopendra, Scorpio, and Zaocys are also known or potential hepatotoxins. For some patients, the clinical course was severe, with risks for acute liver failure, liver transplantation requirement, and lethality. In conclusion, the use of few herbal TCM products may rarely be associated with hepatotoxicity in some susceptible individuals, necessitating a stringent pretreatment evaluation of the risk/benefit ratio, based on results of multicenter, randomized, double-blind, placebo-controlled clinical trials.

Dixon, Robert L.; Boone, John M.

2013-11-15

Purpose: The scanner-reported CTDI{sub vol} for automatic tube current modulation (TCM) has a different physical meaning from the traditional CTDI{sub vol} at constant mA, resulting in the dichotomy “CTDI{sub vol} of the first and second kinds” for which a physical interpretation is sought in hopes of establishing some commonality between the two.Methods: Rigorous equations are derived to describe the accumulated dose distributions for TCM. A comparison with formulae for scanner-reported CTDI{sub vol} clearly identifies the source of their differences. Graphical dose simulations are also provided for a variety of TCM tube current distributions (including constant mA), all having the samemore » scanner-reported CTDI{sub vol}.Results: These convolution equations and simulations show that the local dose at z depends only weakly on the local tube current i(z) due to the strong influence of scatter from all other locations along z, and that the “local CTDI{sub vol}(z)” does not represent a local dose but rather only a relative i(z) ≡ mA(z). TCM is a shift-variant technique to which the CTDI-paradigm does not apply and its application to TCM leads to a CTDI{sub vol} of the second kind which lacks relevance.Conclusions: While the traditional CTDI{sub vol} at constant mA conveys useful information (the peak dose at the center of the scan length), CTDI{sub vol} of the second kind conveys no useful information about the associated TCM dose distribution it purportedly represents and its physical interpretation remains elusive. On the other hand, the total energy absorbed E (“integral dose”) as well as its surrogate DLP remain robust between variable i(z) TCM and constant current i{sub 0} techniques, both depending only on the total mAs = t{sub 0}=i{sub 0} t{sub 0} during the beam-on time t{sub 0}.« less

Since 1999, progress has been made, to varying degrees, in numerous areas of medical history research in China including history of TCM, history of western medicine, history of integrated Chinese and western medicine, history of traditional medicine of Chinese minorities, history of medicine of foreign countries, history of medical exchanges between China and other countries, and history of comparative medical history. Among others, the number of articles on history of diseases, history of specific medical disciplines, modern medical history, medical biographies, medical works, contemporary medical history, and history of medical culture has increased dramatically. In the field of history of diseases, the papers deal with diseases in gynecology and obstetrics, plague, lanhousha (scarlet fever), and nephritis; articles in the field of specific disciplines deal with history of acu-moxibustion, history of prescription-forms, and history of gynecology, endoscopic surgery, and evidence-based medicine. There are even distinguished papers appeared in these aspects. In the aspect of modern medical history, there are papers dealing with the developement of TCM, the introduction of western medicine into China, with some specific researches in these fields. Medical biographies include Tan Yun-xian, Quan Shao-qing, Du Chong-ming etc. Papers on medical works deal with the ancient unearthed literature lost yet spread and extant abroad, medical classics, canons on material medica, cold-pathogenic diseases, and formularies. While papers on history of medical culture discuss basically the influence of Confucianism, Taoism, Buddhism and I-discipline on Chinese medicine. During these five years, 300 original articles have been published in The Chinese journal of Medical History, with another 200 papers published in other Chinese journals. Forty monographs have been published and important ones are A General History of Chinese Medicine, Modern history of TCM, The Historical Development of Acupuncture, A General History of Tiberan Medicine. For the coming years, the stress points should be laid on the research on history of diseases, history of specific medical disciplines, and some specific academic topics. In addition, the weak points in the research fields of theoretical problems in studies of medical history, history of traditional medicine of Chinese minorities, medical history of communication between China and foreign countries, comparative study on medical history, and the study on history of medical also be strengthened continually. In the five years since 1999, progress has been made, more or less, in the research works in medical history in China, including history of TCM, history of western medicine, history of integrated Chinese and western medicine, history of traditional medicine of Chinese minorities, history of medicine of foreign countries, history of medical exchanges between China and other countries, and history of comparative medical history. And the number of articles on history of diseases, history of specific medical disciplines, modern medical history, medical biographies, medical works, contemporary medical history and history of medical culture has increased dramatically. The research work in ancient medical history is still progressing forcefully.

Traditional Chinese medicine (TCM) has been practiced for thousands of years, but only within the last few decades has its use become more widespread outside of Asia. Concerns continue to be raised about the efficacy, legality, and safety of many popular complementary alternative medicines, including TCMs. Ingredients of some TCMs are known to include derivatives of endangered, trade-restricted species of plants and animals, and therefore contravene the Convention on International Trade in Endangered Species (CITES) legislation. Chromatographic studies have detected the presence of heavy metals and plant toxins within some TCMs, and there are numerous cases of adverse reactions. It is in the interests of both biodiversity conservation and public safety that techniques are developed to screen medicinals like TCMs. Targeting both the p-loop region of the plastid trnL gene and the mitochondrial 16S ribosomal RNA gene, over 49,000 amplicon sequence reads were generated from 15 TCM samples presented in the form of powders, tablets, capsules, bile flakes, and herbal teas. Here we show that second-generation, high-throughput sequencing (HTS) of DNA represents an effective means to genetically audit organic ingredients within complex TCMs. Comparison of DNA sequence data to reference databases revealed the presence of 68 different plant families and included genera, such as Ephedra and Asarum, that are potentially toxic. Similarly, animal families were identified that include genera that are classified as vulnerable, endangered, or critically endangered, including Asiatic black bear (Ursus thibetanus) and Saiga antelope (Saiga tatarica). Bovidae, Cervidae, and Bufonidae DNA were also detected in many of the TCM samples and were rarely declared on the product packaging. This study demonstrates that deep sequencing via HTS is an efficient and cost-effective way to audit highly processed TCM products and will assist in monitoring their legality and safety especially when plant reference databases become better established.

To systematically review the effect of traditional Chinese medicine (TCM) in an animal model of lung injury induced by paraquat (PQ), and to provide a theoretical basis for future clinical trials. The Wanfang, CNKI, VIP, PubMed/MEDLINE, EMBASE database (from January 1979 to September 2012) were searched. All papers concerning TCM in animal model of lung injury induced by PQ were retrieved. Study selection and data extraction were performed on the basis of Cochrane systematic review methods. Weighted mean difference (WMD) and 95% confidence interval (95%CI) with random effects model was adopted to investigate the effect of TCM on lung injury induced by PQ. Eighteen papers involving 1 188 rats met our criteria. Meta-analysis showed that TCM could improve the lung coefficiency (WMD -0.07, 95%CI -0.14 to -0.01, P=0.03), reduce lung wet/dry weight ratio (WMD -1.15, 95%CI -2.03 to -0.27, P=0.01), increase the serum superoxide dismutase (SOD) activity (WMD 56.08, 95%CI 23.46 to 88.70, P=0.000 8), improve plasma glutathione peroxidase (GSH-Px) level (WMD 26.64, 95%CI 18.95 to 34.33, P<0.000 01), and lower serum malondialdehyde(MDA) level (WMD -0.65, 95%CI -1.00 to -0.30, P=0.000 2), however there was no significant difference in the level of serum tumor necrosis factor-α (TNF-α) and hydroxyproline(HYP) level between TCM and controls (TNF-α: WMD -25.15, 95%CI -54.87 to 4.57, P=0.10; HYP: WMD -0.11, 95%CI -2.71 to 0.48, P=0.17). These findings demonstrate the efficacy of TCM in animal models of lung injury induced by PQ. However taking account of heterogeneity, the efficacy should be interpreted with caution.

Because of the numerous varieties of herbal species and active ingredients in the traditional Chinese medicine(TCM),the traditional methods employed could hardly satisfy the current determination requirements of TCM.The present work proposed an idea to realize rapid determination of the quality of TCM based on near infrared(NIR)spectroscopy and internet sharing mode. Low cost and portable multi-source composite spectrometer was invented by our group for in-site fast measurement of spectra of TCM samples. The database could be set up by sharing spectra and quality detection data of TCM samples among TCM enterprises based on the internet platform.A novel method called as keeping same relationship between X and Y space based on K nearest neighbors(KNN-KSR for short)was applied to predict the contents of effective compounds of the samples. In addition,a comparative study between KNN-KSR and partial least squares(PLS)was conducted. Two datasets were applied to validate above idea:one was about 58 Ginkgo Folium samples samples measured with four near-infrared spectroscopy instruments and two multi-source composite spectrometers,another one was about 80 corn samples available online measured with three NIR instruments. The results show that the KNN-KSR method could obtain more reliable outcomes without correcting spectrum.However transforming the PLS models to other instruments could hardly acquire better predictive results until spectral calibration is performed. Meanwhile,the similar analysis results of total flavonoids and total lactones of Ginkgo Folium samples are achieved on the multi-source composite spectrometers and near-infrared spectroscopy instruments,and the prediction results of KNN-KSR are better than PLS. The idea proposed in present study is in urgent need of more samples spectra, and then to be verified by more case studies. Copyright© by the Chinese Pharmaceutical Association.

Though Chinese Traditional Medicine (TCM) is one of the most important parts of health care system in China, studies on the epidemiology of depression in TCM are scarce and mental health issues in TCM have been neglected for longtime. This was an interview-based survey. The prevalence of depression and suicidal risk in outpatients at a TCM hospital was identified by a one-stage diagnosing process using the Mini International Neuropsychiatric Interview. Associated risk factors, role impairment, and service utility were also assessed. A total of 2000 outpatients aged from 18 to 65years completed the survey with a response rate of 87.0%. The estimated prevalence of major depressive disorder was 13.2% for lifetime and 4.9% for current. No significant gender differences were found. Depression was more common in patients who lacked social support, experienced family economic burden and health burden, and underwent negative life events, poor self-rated health, or with moderate/severe sleep problem than in their correspondents; all with statistical significance (OR: 1.83-6.82). Patients with depression reported a mean of 82.7days and 99.3days of sick leave due to their physical and mental condition, respectively, which was much longer than those without depression (24.8days and 25.8days, respectively). Only 30.0% of patients with depression sought professional help from psychiatrists/psychologists or used antidepressants. The recall bias could not be ruled out in this study and could have led to an underestimation of true prevalence and the unmet need for treatment. Since this study was cross-sectional, the causal relationships between sociodemographic factors and depression cannot be determined. Depression is common at TCM hospitals. The impairments due to depression are striking, and unmet needs for treatment are pervasive. Consequently, mental health services in TCM should not be neglected any longer.

Many medical centers in Taiwan have started to provide Traditional Chinese Medicine (TCM) services for hospitalized patients. Due to the complexity of TCM modality and the increasing need for providing TCM services for patients in different wards at distantly separate locations within the hospital, it is getting difficult to manage the situation in the traditional way. A computerized system with mobile ability can therefore provide a practical solution to the challenge presented. The study tries to develop a cloud system equipped with mobile devices to integrate electronic medical records, facilitate communication between medical workers, and improve the quality of TCM services for the hospitalized patients in a medical center. The system developed in the study includes mobile devices carrying Android operation system and a PC as a cloud server. All the devices use the same TCM management system developed by the study. A website of database is set up for information sharing. The cloud system allows users to access and update patients' medical information, which is of great help to medical workers for verifying patients' identification and giving proper treatments to patients. The information then can be wirelessly transmitted between medical personnel through the cloud system. Several quantitative and qualitative evaluation indexes are developed to measure the effectiveness of the cloud system on the quality of the TCM service. The cloud system is tested and verified based on a sample of hospitalized patients receiving the acupuncture treatment at the Lukang Branch of Changhua Christian Hospital (CCH) in Taiwan. The result shows a great improvement in operating efficiency of the TCM service in that a significant saving in labor time can be attributable to the cloud system. In addition, the cloud system makes it easy to confirm patients' identity through taking a picture of the patient upon receiving any medical treatment. The result also shows that the cloud system achieves significant improvement in the acupuncture treatment. All the acupuncture needles now can be removed at the time they are expected to be removed. Furthermore, through the cloud system, medical workers can access and update patients' medical information on-site, which provides a means of effective communication between medical workers. These functions allow us to make the most use of the portability feature of the acupuncture service. The result shows that the contribution made by the cloud system to the TCM service is multi-dimensional: cost-effective, environment-protective, performance-enhancing etc. Developing and implementing such a cloud system for the TCM service in Taiwan symbolizes a pioneering effort. We believe that the work we have done here can serve as a stepping-stone toward advancing the TCM service quality in the future.

Neurodegenerative diseases, referring to as the progressive loss of structure and function of neurons, constitute one of the major challenges of modern medicine. Traditional Chinese herbs have been used as a major preventive and therapeutic strategy against disease for thousands years. The numerous species of medicinal herbs and Traditional Chinese Medicine (TCM) compound formulas in nervous system disease therapy make it a large chemical resource library for drug discovery. In this work, we collected 7362 kinds of herbs and 58,147 Traditional Chinese medicinal compounds (Tcmcs). The predicted active compounds in herbs have good oral bioavailability and central nervous system (CNS) permeability. The molecular docking and network analysis were employed to analyze the effects of herbs on neurodegenerative diseases. In order to evaluate the predicted efficacy of herbs, automated text mining was utilized to exhaustively search in PubMed by some related keywords. After that, receiver operator characteristic (ROC) curves was used to estimate the accuracy of predictions. Our study suggested that most herbs were distributed in family of Asteraceae, Fabaceae, Lamiaceae and Apocynaceae. The predictive model yielded good sensitivity and specificity with the AUC values above 0.800. At last, 504 kinds of herbs were obtained by using the optimal cutoff values in ROC curves. These 504 herbs would be the most potential herb resources for neurodegenerative diseases treatment. This study would give us an opportunity to use these herbs as a chemical resource library for drug discovery of anti-neurodegenerative disease. Copyright © 2016 Elsevier Masson SAS.

Chinese medicine prescriptions are the wisdom outcomes of traditional Chinese medicine (TCM) clinical treatment determinations which based on differentiation of symptoms and signs. Chinese medicine prescriptions are also the basis of secondary exploitation of TCM. The study on prescription helps to understand the material basis of its efficacy, pharmacological mechanism, which is an important guarantee for the modernization of traditional Chinese medicine. Currently, there is not yet dissertation n the method and technology system of basic research on the prescription of Chinese medicine. This paper focuses on how to build an effective system of prescription research technology. Based on "component structure" theory, a technology system contained four-step method that "prescription analysis, the material basis screening, the material basis of analysis and optimization and verify" was proposed. The technology system analyzes the material basis of the three levels such as Chinese medicine pieces, constituents and the compounds which could respect the overall efficacy of Chinese medicine. Ideas of prescription optimization, remodeling are introduced into the system. The technology system is the combination of the existing research and associates with new techniques and methods, which used for explore the research thought suitable for material basis research and prescription remodeling. The system provides a reference for the secondary development of traditional Chinese medicine, and industrial upgrading.

Stable angina pectoris is experienced as trans-sternal or retro-sternal pressure or pain that may radiate to the left arm, neck or back. Although available evidence relating to its effectiveness and mechanism are weak, traditional Chinese medicine is used as an alternative therapy for stable angina pectoris. We report a protocol of a randomized controlled trial using traditional Chinese medicine to investigate the effectiveness, mechanism and safety for patients with stable angina pectoris. This is a north-east Chinese, multi-center, multi-blinded, placebo-controlled and superiority randomized trail. A total of 240 patients with stable angina pectoris will be randomly assigned to three groups: two treatment groups and a control group. The treatment groups will receive Chinese herbal medicine consisting of Yi-Qi-Jian-Pi and Qu-Tan-Hua-Zhuo granule and Yi-Qi-Jian-Pi and Qu-Tan-Hua-Yu granule, respectively, and conventional medicine. The control group will receive placebo medicine in addition to conventional medicine. All 3 groups will undergo a 12-week treatment and 2-week follow-up. Four visits in sum will be scheduled for each subject: 1 visit each in week 0, week 4, week 12 and week 14. The primary outcomes include: the frequency of angina pectoris attack; the dosage of nitroglycerin; body limited dimension of Seattle Angina Questionnaire. The secondary outcomes include: except for the body limited dimension of SAQ, traditional Chinese medicine pattern questionnaire and so on. Therapeutic mechanism outcomes, safety outcomes and endpoint outcomes will be also assessed. The primary aim of this trial is to develop a standard protocol to utilize high-quality EBM evidence for assessing the effectiveness and safety of SAP via TCM pattern differentiation as well as exploring the efficacy mechanism and regulation with the molecular biology and systems biology.

A recent research demonstrates that the inhibition of mammalian target of rapamycin (mTOR) improves survival and health for patients with Leigh syndrome. mTOR proteins can be treated as drug target proteins against Leigh syndrome and other mitochondrial disorders. In this study, we aim to identify potent TCM compounds from the TCM Database@Taiwan as lead compounds of mTOR inhibitors. PONDR-Fit protocol was employed to predict the disordered disposition in mTOR protein before virtual screening. After virtual screening, the MD simulation was employed to validate the stability of interactions between each ligand and mTOR protein in the docking poses from docking simulation. The top TCM compounds, picrasidine M and acerosin, have higher binding affinities with target protein in docking simulation than control. There have H-bonds with residues Val2240 and π interactions with common residue Trp2239. After MD simulation, the top TCM compounds maintain similar docking poses under dynamic conditions. The top two TCM compounds, picrasidine M and acerosin, were extracted from Picrasma quassioides (D. Don) Benn. and Vitex negundo L. Hence, we propose the TCM compounds, picrasidine M and acerosin, as potential candidates as lead compounds for further study in drug development process with the mTOR protein against Leigh syndrome and other mitochondrial disorders.

Chronic hepatitis B (CHB) is a serious public health problem, and Traditional Chinese Medicine (TCM) plays an important role in the control and treatment for CHB. In the treatment of TCM, zheng discrimination is the most important step. In this paper, an approach based on CFS-GA (Correlation based Feature Selection and Genetic Algorithm) and C5.0 boost decision tree is used for zheng classification and progression in the TCM treatment of CHB. The CFS-GA performs better than the typical method of CFS. By CFS-GA, the acquired attribute subset is classified by C5.0 boost decision tree for TCM zheng classification of CHB, and C5.0 decision tree outperforms two typical decision trees of NBTree and REPTree on CFS-GA, CFS, and nonselection in comparison. Based on the critical indicators from C5.0 decision tree, important lab indicators in zheng progression are obtained by the method of stepwise discriminant analysis for expressing TCM zhengs in CHB, and alterations of the important indicators are also analyzed in zheng progression. In conclusion, all the three decision trees perform better on CFS-GA than on CFS and nonselection, and C5.0 decision tree outperforms the two typical decision trees both on attribute selection and nonselection.

Nondisclosure of traditional and complementary medicine (T&CM) use may cause individual to be at risk of undue harm. This study aimed to explore patient's experience and views on their decision to disclose the use of T&CM to the doctor. An exploratory qualitative study using in-depth interview involving 10 primary care clinics attendees in Kuching was conducted. The results indicated that disclosure of T&CM use will motivate them to get information, increase doctor's awareness, and get support from family and friends for disclosure. Fear of negative relationship and negative response from doctors was a barrier for disclosure. Doctor's interpersonal and communication skills of being involved, treating patients respectfully, listening attentively, respecting privacy, and taking time for the patient were a critical component for disclosure. Intrapersonal trust regarding doctor influences their satisfaction on healthcare. Women are more open and receptive to a health concern and expressing negative emotions and tend to share problems, whereas men always described themselves as healthy, tended to keep their own personal feeling to themselves, and tended to not share. The doctor should consider gender differences in disclosure, their attitude towards T&CM use, and gained patient's trust in the delivery of healthcare services. Good interpersonal and communication skills must be maintained between doctor and patients. PMID:29636778

Traditional Chinese Medicine (TCM) has been developed for thousands of years and has formed an integrated theoretical system based on a large amount of clinical practice. However, essential ingredients in TCM herbs have not been fully identified, and their precise mechanisms and targets are not elucidated. In this study, a new strategy combining comprehensive two-dimensional K562/cell membrane chromatographic system and in silico target identification was established to characterize active components from Indigo naturalis, a famous TCM herb that has been widely used for the treatment of leukemia in China, and their targets. Three active components, indirubin, tryptanthrin and isorhamnetin, were successfully characterized and their anti-leukemia effects were validated by cell viability and cell apoptosis assays. Isorhamnetin, with undefined cancer related targets, was selected for in silico target identification. Proto-oncogene tyrosine-protein kinase (Src) was identified as its membrane target and the dissociation constant (Kd) between Src and isorhamnetin was 3.81 μM. Furthermore, anti-leukemia effects of isorhamnetin were mediated by Src through inducing G2/M cell cycle arrest. The results demonstrated that the integrated strategy could efficiently characterize active components in TCM and their targets, which may bring a new light for a better understanding of the complex mechanism of herbal medicines.

Traditional Chinese medicine (TCM) has been accepted as a complementary therapy for knee osteoarthritis. However, the efficacy and safety of the intervention were still conflicting and uncertain. Meanwhile, the quality of methodology and evidence in the field was unknown. To summarize the characteristics and critically evaluate the quality of methodology, as well as the evidence of systematic reviews (SRs) on TCM for knee osteoarthritis. Five electronic databases were searched from inception to April 2016. The methodological quality of the included studies was assessed by AMSTAR and ROBIS. The quality of the evidence was determined using the GRADE approach. Ten SRs were included. The conclusions suggest that TCM provides potential benefits for patients with knee osteoarthritis. These benefits include pain relief, functional improvement, and presence of few adverse events. Limitations of the methodological quality mainly included the lack of a-priori protocol or protocol registration and incomprehensive literature search. A list of excluded studies was also not provided. The overall quality of evidence in the SRs was poor, ranging from "very low" to "low," mainly because of the serious risk of bias of original trials, inconsistencies, and imprecision in the outcomes. TCM generally appears to be effective for knee osteoarthritis treatment. However, the evidence is not robust enough because of the methodological flaws in SRs. Hence, these conclusions on available SRs should be treated with caution for clinical practice.

Due to language limitations, the abstract of journal article may be the only way for people of non-Chinese speaking countries to know about trials in traditional Chinese medicine (TCM). However, little is known about the reporting quality of these trial abstracts. Our study is to assess the reporting quality of abstracts of randomized controlled trials (RCT) published in four leading Chinese medical journals of TCM, and to identify any differences in reporting between the Chinese and English version of the same abstract publication. Two reviewers hand-searched the Chinese Journal of Integrated Traditional and Western Medicine, the Chinese Journal of Integrative Medicine, the China Journal of Chinese Materia Medica and the Chinese Acupuncture & Moxibustion for all abstracts of RCTs published between 2006 and 2007. Two reviewers independently assessed the reporting quality of the Chinese and English version of all eligible abstracts based on a modified version of the CONSORT for reporting randomised trials in journal and conference abstracts (CONSORT for abstracts). We identified a total of 345 RCTs of TCM with both a Chinese and English abstract. More than half of Chinese abstracts reported details of the trial participants (68%; 234/345), control group intervention (52%; 179/345), the number of participants randomized (73%; 253/345) and benefits when interpreting the trial results (55%; 190/345). Reporting of methodological quality or key features of trial design and trial results were poor; only 2% (7/345) included details of the trial design, 3% (11/345) defined the primary outcome, 5% (17/345) described the methods of random sequence generation, and only 4% (13/345) reported the number of participants analyzed. No abstracts provided details on allocation concealment and trial registration. The percentage agreement in reporting (between the Chinese and English version of the same abstract) ranged from 84% to 100% across individual checklist item. The reporting quality of abstracts of RCTs published in these four TCM journals needs to be improved. Since none of the four journals adopted CONSORT for Abstracts, we hope that the introduction and adoption of CONSORT for Abstracts by TCM journals will lead to an improvement in reporting quality.

Alzheimer' disease (AD) is an ultimately fatal degenerative brain disorder that has an increasingly large burden on health and social care systems. There are only five drugs for AD on the market, and no new effective medicines have been discovered for many years. Chinese medicinal plants have been used to treat diseases for thousands of years, and screening herbal remedies is a way to develop new drugs. We used molecular docking to screen 30,438 compounds from Traditional Chinese Medicine (TCM) against a comprehensive list of AD target proteins. TCM compounds in the top 0.5% of binding affinity scores for each target protein were selected as our research objects. Structural similarities between existing drugs from DrugBank database and selected TCM compounds as well as the druggability of our candidate compounds were studied. Finally, we searched the CNKI database to obtain studies on anti-AD Chinese plants from 2007 to 2017, and only clinical studies were included. A total of 1,476 compounds (top 0.5%) were selected as drug candidates. Most of these compounds are abundantly found in plants used for treating AD in China, especially the plants from two genera Panax and Morus. We classified the compounds by single target and multiple targets and analyzed the interactions between target proteins and compounds. Analysis of structural similarity revealed that 17 candidate anti-AD compounds were structurally identical to 14 existing approved drugs. Most of them have been reported to have a positive effect in AD. After filtering for compound druggability, we identified 11 anti-AD compounds with favorable properties, seven of which are found in anti-AD Chinese plants. Of 11 anti-AD compounds, four compounds 5,862, 5,863, 5,868, 5,869 have anti-inflammatory activity. The compound 28,814 mainly has immunoregulatory activity. The other six compounds have not yet been reported for any biology activity at present. Natural compounds from TCM provide a broad prospect for the screening of anti-AD drugs. In this work, we established networks to systematically study the connections among natural compounds, approved drugs, TCM plants and AD target proteins with the goal of identifying promising drug candidates. We hope that our study will facilitate in-depth research for the treatment of AD in Chinese medicine.

To survey the reporting quality of traditional Chinese medicine (TCM) case reports published in recent years and understand the common problems. The assessment results would lay the foundation for the development of recommendations for case report in Chinese medicine. This survey determined the reporting quality of cases with Chinese herbal decoction, Chinese proprietary medicine, acupuncture, moxibustion and other traditional therapies published in 20 core medical journals of China by searching the China Academic Journals Full-text Database from 2006 to 2010. Fifty survey items in 16 domains were used to determine the reporting quality. One point was assigned to each item (Yes=1 point; No=0 point), and total score was 50 points. The domain of treatment was assessed independently, ranging from 2 to 9 items for different TCM interventions. The total of 1,858 case reports, covering 3,417 cases were included to analyze from 13 out of 20 core medical journals of China. There were 74.8% of them did not identify the nature of study in title, while 73.9% did not comprise an abstract. Incomplete reporting was found in discussions/ comment, and only 38.9% had made recommendations or take-away messages. Figures and tables were infrequently used. Three cases cited the full names of patients, but without declaring that any consent was obtained. Over 90% reported the symptoms and signs of TCM, and characteristics on tongue and pulse, but less than 50% did mention other medical history and diagnostic rationale. More than 90% treatments of the included cases were herbal decoction, with clear reporting on the ingredients and dosages. However, the reporting rate of the dosages of each ingredient was just 48.4%. Almost none reported the quality control of crude herbs, manufacturers and lot numbers of herbal proprietary medicine. Besides, advices and precautions on diet, emotions and living were rare to be illustrated. Systematic reporting recommendations are urged to develop for improving the contents and format of case reports in TCM.

Traditional Chinese medicine and Western psychopharmacology: building bridges.

This paper demonstrates that in the treatment of psychiatric disorders, there are striking similarities between the mechanisms of psychoactive agents used in Traditional Chinese Medicine (TCM) and those of western psychopharmacology. While western researchers search for new treatments and novel mechanisms of action, investigators in Asia are analyzing traditional remedies in order to understand the mechanisms responsible for their effectiveness. A review of contemporary pharmacologic studies of agents used in TCM for psychiatric indications reveals that virtually all of the active principles of drug action established in 20th century psychopharmacology were encountered empirically in Chinese herbal medicine over the past 2000 years. Building bridges between these two traditions may thus be of benefit to both cultures. In addition to providing western patients with a wider selection of treatment options, the effort may help Asian clinicians and researchers avoid some of the errors that have troubled their western counterparts.

Acquired immunodeficiency syndrome (AIDS), caused by human immunodeficiency virus (HIV), has become, because of the rapid spread of the disease, a serious global problem and cannot be treated. Recent studies indicate that VIF is a protein of HIV to prevent all of human immunity to attack HIV. Molecular compounds of traditional Chinese medicine (TCM) database filtered through molecular docking and molecular dynamics simulations to inhibit VIF can protect against HIV. Glutamic acid, plantagoguanidinic acid, and Aurantiamide acetate based docking score higher with other TCM compounds selected. Molecular dynamics are useful for analysis and detection ligand interactions. According to the docking position, hydrophobic interactions, hydrogen bonding changes, and structure variation, the study try to select the efficacy of traditional Chinese medicine compound Aurantiamide acetate is better than the other for protein-ligand interactions to maintain the protein composition, based on changes in the structure.

Ischemic stroke and ischemia/reperfusion (I/R) injury induced by thrombolytic therapy are conditions with high mortality and serious long-term physical and cognitive disabilities. They have a major impact on global public health. These disorders are associated with multiple insults to the cerebral microcirculation, including reactive oxygen species (ROS) overproduction, leukocyte adhesion and infiltration, brain blood barrier (BBB) disruption, and capillary hypoperfusion, ultimately resulting in tissue edema, hemorrhage, brain injury and delayed neuron damage. Traditional Chinese medicine (TCM) has been used in China, Korea, Japan and other Asian countries for treatment of a wide range of diseases. In China, the usage of compound TCM preparation to treat cerebrovascular diseases dates back to the Han Dynasty. Even thousands of years earlier, the medical formulary recorded many classical prescriptions for treating cerebral I/R-related diseases. This review summarizes current information and underlying mechanisms regarding the ameliorating effects of compound TCM preparation, Chinese materia medica, and active components on I/R-induced cerebral microcirculatory disturbances, brain injury and neuron damage.
