The development of an effective classification method for human health conditions is essential for precise diagnosis and delivery of tailored therapy to individuals. Contemporary classification of disease systems has properties that limit its information content and usability. Chinese medicine pattern classification has been incorporated with disease classification, and this integrated classification method became more precise because of the increased understanding of the molecular mechanisms. However, we are still facing the complexity of diseases and patterns in the classification of health conditions. With continuing advances in omics methodologies and instrumentation, we are proposing a new classification approach: molecular module classification, which is applying molecular modules to classifying human health status. The initiative would be precisely defining the health status, providing accurate diagnoses, optimizing the therapeutics and improving new drug discovery strategy. Therefore, there would be no current disease diagnosis, no disease pattern classification, and in the future, a new medicine based on this classification, molecular module medicine, could redefine health statuses and reshape the clinical practice.

Information seeking is one of human needs today. Comparing things using search engine surely take more times than search only one thing. In this paper, we analyzed comparative questions for comparative question answering system. Comparative question is a question that comparing two or more entities. We grouped comparative questions into 5 types: selection between mentioned entities, selection between unmentioned entities, selection between any entity, comparison, and yes or no question. Then we extracted 4 types of information from comparative questions: entity, aspect, comparison, and constraint. We built classifiers for classification task and information extraction task. Features used for classification task are bag of words, whether for information extraction, we used lexical, 2 previous and following words lexical, and previous label as features. We tried 2 scenarios: classification first and extraction first. For classification first, we used classification result as a feature for extraction. Otherwise, for extraction first, we used extraction result as features for classification. We found that the result would be better if we do extraction first before classification. For the extraction task, classification using SMO gave the best result (88.78%), while for classification, it is better to use naïve bayes (82.35%).

Determine optimal weightings of Peer Assessment Rating (PAR) index and Discrepancy Index (DI) for malocclusion severity assessment in Chinese orthodontic patients. Sixty-nine Chinese orthodontists assessed a full set of pre-treatment records from a stratified random sample of 120 subjects gathered from six university orthodontic centres. Using professional judgment as the outcome variable, multiple regression analyses were performed to derive customized weighting systems for the PAR index and DI, for all subjects and each Angle classification subgroup. Professional judgment was consistent, with an Intraclass Correlation Coefficient (ICC) of 0.995. The PAR index or DI can be reliably measured, with ICC = 0.959 and 0.990, respectively. The predictive accuracy of PAR index was greatly improved by the Chinese weighting process (from r = 0.431 to r = 0.788) with almost equal distribution in each Angle classification subgroup. The Chinese-weighted DI showed a higher predictive accuracy, at P = 0.01, compared with the PAR index (r = 0.851 versus r = 0.788). A better performance was found in the Class II group (r = 0.890) when compared to Class I (r = 0.736) and III (r = 0.785) groups. The Chinese-weighted PAR index and DI were capable of predicting 62 per cent and 73 per cent of total variance in the professional judgment of malocclusion severity in Chinese patients. Differential prediction across Angle classifications merits attention since different weighting formulas were found.

Cultures in psychiatric nosology: the CCMD-2-R and international classification of mental disorders.

PubMed

Lee, S

1996-12-01

This essay reviews the Chinese Classification of Mental Disorders, Second Edition, Revised (CCMD-2-R, 1995), by assuming the theoretical stance that symptom recognition, disease construction, and taxonomic strategy in psychiatry reflect, and are constrained by, the cultural norms and values as well as the political and economic organizations of the society in which they are embedded. The CCMD-2-R is an ethnomedical classification grounded in both symptomatology and etiology, in which Chinese psychiatrists seek to conform with international classifications on the one hand, and to sustain a nosology with Chinese cultural characteristics on the other. Although broad similarities between the ICD-10 and CCMD-2-R are evident, their blending is legitimately incomplete. Thus, the particular additions (e.g., travelling psychosis, qigong induced mental disorders), deletions (e.g., somatoform disorders, pathological gambling, a number of personality and sexual disorders), retentions (e.g., unipolar mania, neurosis, hysteria, homosexuality), and variations (e.g., depressive neurosis, neurasthenia) reveal not only the changing notions of illness but also the shifting social realities in contemporary China. The CCMD-2-R will be widely used by Chinese psychiatrists and should standardize diagnostic practice and facilitate research, but its impact on everyday clinical work and psychiatric training remains to be evaluated. For Western researchers, it is one avenue for achieving an understanding of the Chinese social world, and should usefully be contrasted with the ICD-10 and DSM-IV as the move towards an international nosology continues.

In the Western medicine system, scholars have explained individual differences in terms of behaviour and thinking, leading to the emergence of various classification theories on individual differences. Traditional Chinese medicine has long observed human constitutions. Modern Chinese medicine studies have also involved study of human constitutions; however, differences exist in the ways traditional and modern Chinese medicine explore individual constitutions. In the late 1970s, the constitutional theory of Chinese medicine was proposed. This theory takes a global and dynamic view of human differences (e.g., the shape of the human body, function, psychology, and other characteristics) based on arguments from traditional Chinese medicine. The establishment of a standard for classifying constitutions into nine modules was critical for clinical application of this theory. In this review, we describe the history and recent research progress of this theory, and compare it with related studies in the western medicine system. Several research methods, including philology, informatics, epidemiology, and molecular biology, in classifying constitutions used in the constitutional theory of Chinese medicine were discussed. In summary, this constitutional theory of Chinese medicine can be used in clinical practice and would contribute to health control of patients.

An electronic nose (e-nose) was designed to classify Chinese liquors of the same aroma style. A new method of feature reduction which combined feature selection with feature extraction was proposed. Feature selection method used 8 feature-selection algorithms based on information theory and reduced the dimension of the feature space to 41. Kernel entropy component analysis was introduced into the e-nose system as a feature extraction method and the dimension of feature space was reduced to 12. Classification of Chinese liquors was performed by using back propagation artificial neural network (BP-ANN), linear discrimination analysis (LDA), and a multi-linear classifier. The classificationmore » rate of the multi-linear classifier was 97.22%, which was higher than LDA and BP-ANN. Finally the classification of Chinese liquors according to their raw materials and geographical origins was performed using the proposed multi-linear classifier and classification rate was 98.75% and 100%, respectively.« less

A group of Mainland Chinese engineering students were asked to respond to 12 questions by indicating their design conventions and expectations about operations, directions-of-motion, and descriptions of movement for items such as doors, keys, taps, and knobs. Chi-square tests demonstrated strong response stereotypes for tasks of all 12 questions. A comparison of the stereotype strengths found here with that of Hong Kong Chinese and American engineering students reported earlier indicated that stereotype strengths of engineering students from the three regions were generally different. For some cases stereotype characteristics of two regions were more alike than the other, and also for some subjects in the three regions performed similarly. The Mainland and Hong Kong Chinese were more alike in making their choices on questions of conceptual compatibility, while more consistent preferences on movement compatibility and spatial compatibility were noted between the Mainland Chinese and American students than Hong Kong Chinese.

2016-03-01

Different brands of Chinese vinegar are similar in appearance, color and aroma, making their discrimination difficult. The compositions and concentrations of the volatiles released from different vinegars vary by raw material and brewing process and thus offer a means to discriminate vinegars. In this study, we enhanced the detection sensitivity of the infrared spectrometer by extending its optical path. We measured the infrared spectra of the volatiles from 5 brands of Chinese vinegar and observed the spectral characteristics corresponding to alcohols, esters, acids, furfural, etc. Different brands of Chinese vinegar had obviously different infrared spectra and could be classified through chemometrics analysis. Furthermore, we established classification models and demonstrated their effectiveness for classifying different brands of vinegar. This study demonstrates that long-optical-path infrared spectroscopy has the ability to discriminate Chinese vinegars with the advantages that it is fast and non-destructive and eliminates the need for sampling.

To explore a crown form classification method for upper central incisor which is more objective and scientific than traditional classification method based on the standardized photography technique. To analyze the relationship between crown form of upper central incisors and papilla filling in periodontally healthy Chinese Han-nationality youth. In the study, 180 periodontally healthy Chinese youth ( 75 males, and 105 females ) aged 20-30 (24.3±4.5) years were included. With the standardized upper central incisor photography technique, pictures of 360 upper central incisors were obtained. Each tooth was classified as triangular, ovoid or square by 13 experienced specialist majors in prothodontics independently and the final classification result was decided by most evaluators in order to ensure objectivity. The standardized digital photo was also used to evaluate the gingival papilla filling situation. The papilla filling result was recorded as present or absent according to naked eye observation. The papilla filling rates of different crown forms were analyzed. Statistical analyses were performed with SPSS 19.0. The proportions of triangle, ovoid and square forms of upper central incisor in Chinese Han-nationality youth were 31.4% (113/360), 37.2% (134/360) and 31.4% (113/360 ), respectively, and no statistical difference was found between the males and females. Average κ value between each two evaluators was 0.381. Average κ value was raised up to 0.563 when compared with the final classification result. In the study, 24 upper central incisors without contact were excluded, and the papilla filling rates of triangle, ovoid and square crown were 56.4% (62/110), 69.6% (87/125), 76.2% (77/101) separately. The papilla filling rate of square form was higher (P=0.007). The proportion of clinical crown form of upper central incisor in Chinese Han-nationality youth is obtained. Compared with triangle form, square form is found to favor a gingival papilla that fills the interproximal embrasure space. The consistency of the present classification method for upper central incisor is not satisfying, which indicates that a new classification method, more scientific and objective than the present one, is to be found.

Poplar tree gum has a similar chemical composition and appearance to Chinese propolis (bee glue) and has been widely used as a counterfeit propolis because Chinese propolis is typically the poplar-type propolis, the chemical composition of which is determined mainly by the resin of poplar trees. The discrimination of Chinese propolis from poplar tree gum is a challenging task. To develop a rapid thin-layer chromatographic (TLC) identification method using chemometric fingerprinting to discriminate Chinese propolis from poplar tree gum. A new TLC method using a combination of ammonia and hydrogen peroxide vapours as the visualisation reagent was developed to characterise the chemical profile of Chinese propolis. Three separate people performed TLC on eight Chinese propolis samples and three poplar tree gum samples of varying origins. Five chemometric methods, including similarity analysis, hierarchical clustering, k-means clustering, neural network and support vector machine, were compared for use in classifying the samples based on their densitograms obtained from the TLC chromatograms via image analysis. Hierarchical clustering, neural network and support vector machine analyses achieved a correct classification rate of 100% in classifying the samples. A strategy for TLC identification of Chinese propolis using chemometric fingerprinting was proposed and it provided accurate sample classification. The study has shown that the TLC identification method using chemometric fingerprinting is a rapid, low-cost method for the discrimination of Chinese propolis from poplar tree gum and may be used for the quality control of Chinese propolis.

Objective tongue color analysis is an important research point for tongue diagnosis in Traditional Chinese Medicine. In this paper a research based on the clinical process of diagnosing tongue color is reported. The color data in RGB color space were first transformed into the data in CIELAB color space, and the color gamut of the displayed tongue was obtained. Then a numerical method of tongue color classification based on the Traditional Chinese Medicine (for example: light white tongue, light red tongue, red tongue) was developed. The conclusion is that this research can give the description and classification of the tongue color close to those given by human vision and may be carried out in clinical diagnosis.

We report an application of data fusion for chemometric classification of 135 canned samples of Chinese lager beers by manufacturer based on the combination of fluorescence, UV and visible spectroscopies. Right-angle synchronous fluorescence spectra (SFS) at three wavelength difference Δλ=30, 60 and 80 nm and visible spectra in the range 380-700 nm of undiluted beers were recorded. UV spectra in the range 240-400 nm of diluted beers were measured. A classification model was built using principal component analysis (PCA) and linear discriminant analysis (LDA). LDA with cross-validation showed that the data fusion could achieve 78.5-86.7% correct classification (sensitivity), while those rates using individual spectroscopies ranged from 42.2% to 70.4%. The results demonstrated that the fluorescence, UV and visible spectroscopies complemented each other, yielding higher synergic effect. Copyright © 2015 Elsevier Ltd. All rights reserved.

Body constitution classification is the basis and core content of traditional Chinese medicine constitution research. It is to extract the relevant laws from the complex constitution phenomenon and finally build the constitution classification system. Traditional identification methods have the disadvantages of inefficiency and low accuracy, for instance, questionnaires. This paper proposed a body constitution recognition algorithm based on deep convolutional neural network, which can classify individual constitution types according to face images. The proposed model first uses the convolutional neural network to extract the features of face image and then combines the extracted features with the color features. Finally, the fusion features are input to the Softmax classifier to get the classification result. Different comparison experiments show that the algorithm proposed in this paper can achieve the accuracy of 65.29% about the constitution classification. And its performance was accepted by Chinese medicine practitioners.

The paper shows how sustainability questions relate to the local space. The local place is not a static entity, but a dynamic one, undergoing constant changes, and it is the rapid social and material processes within the given local situation that is a challenge for the Chinese villages and their integrity. The following article considers the cohesion between the dwellers' emotional co-ownership of their local space and the sustainability process as a driving force in social, economic and ecological development. We bring together the classification of the seven fields of encounter, which were developed out of the empirical data of the Chinese case study villages, and sustainability oriented management considerations for all levels of this concept. We do not pretend to know the solutions, but describe a set of interrelated fields that can be anchor points for placing the solutions and show in which fields action and intervention is possible. In our concept of sustainability, every spatial field has its special meaning, needs special measures and policies and has different connotations to concepts like responsibility, family values or communication systems. We see the social sustainability process as a support for the empowerment of the local dwellers, and the SUCCESS research has encouraged the villages to find suitable sustainability oriented solutions for their natural and societal situation. Before entering the discussion about the chances and potential of a sustainability approach for the Chinese villages, it is first necessary to accept the fact that rural villages play a primordial role in Chinese society and that their potential can strengthen future pathways for China.

The evaluation of permeability in biopharmaceutics classification system of Chinese materia medica (CMMBCS) requires multicomponent as a whole in order to conduct research, even in the study of a specific component, should also be put in the multicomponent environment. Based on this principle, the high content components in Gegen Qinlian decoction were used as multicomponent environmental impact factors in the experiment, and the relevant parameters of intestinal permeability about puerarin were measured with using in situ single-pass intestinal perfusion model, to investigate and evaluate the intestinal permeability of puerarin with other high content components. The experimental results showed that different proportions of baicalin, glycyrrhizic acid and berberine had certain influence on intestinal permeability of puerarin, and glycyrrhizic acid could significantly inhibit the intestinal absorption of puerarin, moreover, high concentration of berberine could promote the absorption of puerarin. The research results indicated that the important research ideas of permeability evaluation in biopharmaceutics classification system of Chinese materia medica with fully considering the effects of other ingredients in multicomponent environment.

Drawing accurate crop cultivation acreage, dynamic monitoring of crops growing and yield forecast are some important applications of remote sensing to agriculture. During the 8th 5-Year Plan period, the task of yield estimation using remote sensing technology for the main crops in major production regions in China once was a subtopic to the national research task titled "Study on Application of Remote sensing Technology". In 21 century in a movement launched by Chinese Ministry of Agriculture to combine high technology to farming production, remote sensing has given full play to farm crops' growth monitoring and yield forecast. And later in 2001 Chinese Ministry of Agriculture entrusted the Northern China Center of Agricultural Remote Sensing to forecast yield of some main crops like wheat, maize and rice in rather short time to supply information for the government decision maker. Present paper is a report for this task. It describes the application of background parameters in image recognition, classification and mapping with focuses on plan of the geo-science's theory, ecological feature and its cartographical objects or scale, the study of phrenology for image optimal time for classification of the ground objects, the analysis of optimal waveband composition and the application of background data base to spatial information recognition ;The research based on the knowledge of background parameters is indispensable for improving the accuracy of image classification and mapping quality and won a secondary reward of tech-science achievement from Chinese Ministry of Agriculture.

Cui, Xiaohui; Yang, Nanhai; Wang, Zhibo

Here, it is reported that there are hundreds of thou- sands of deaths caused by seasonal flu all around the world every year. More other diseases such as chickenpox, malaria, etc. are also serious threats to people’s physical and mental health. There are 250,000–500,000 deaths every year around the world. Therefore proper techniques for disease surveillance are highly demanded. Recently, social media analysis is regarded as an efficient way to achieve this goal, which is feasible since growing number of people have been posting their health information on social media such as blogs, personal websites, etc. Previous work on socialmore » media analysis mainly focused on English materials but hardly considered Chinese materials, which hinders the application of such technique to Chinese peo- ple. In this paper, we proposed a new method of Chinese social media analysis for disease surveillance. More specifically, we compared different kinds of methods in the process of classification and then proposed a new way to process Chinese text data. The Chinese Sina micro-blog data collected from September to December 2013 are used to validate the effectiveness of the proposed method. The results show that a high classification precision of 87.49 % in average has been obtained. Comparing with the data from the authority, Chinese National Influenza Center, we can predict the outbreak time of flu 5 days earlier.« less

A method of neighbor classes based SVM classification for optical printed Chinese character recognition.

Zhang, Jie; Wu, Xiaohong; Yu, Yanmei; Luo, Daisheng

2013-01-01

In optical printed Chinese character recognition (OPCCR), many classifiers have been proposed for the recognition. Among the classifiers, support vector machine (SVM) might be the best classifier. However, SVM is a classifier for two classes. When it is used for multi-classes in OPCCR, its computation is time-consuming. Thus, we propose a neighbor classes based SVM (NC-SVM) to reduce the computation consumption of SVM. Experiments of NC-SVM classification for OPCCR have been done. The results of the experiments have shown that the NC-SVM we proposed can effectively reduce the computation time in OPCCR.

A brain-computer interface (BCI) is a new communication channel between humans and computers that translates brain activity into recognizable command and control signals. Attended events can evoke P300 potentials in the electroencephalogram. Hence, the P300 has been used in BCI systems to spell, control cursors or robotic devices, and other tasks. This paper introduces a novel P300 BCI to communicate Chinese characters. To improve classification accuracy, an optimization algorithm (particle swarm optimization, PSO) is used for channel selection (i.e., identifying the best electrode configuration). The effects of different electrode configurations on classification accuracy were tested by Bayesian linear discriminant analysis offline. The offline results from 11 subjects show that this new P300 BCI can effectively communicate Chinese characters and that the features extracted from the electrodes obtained by PSO yield good performance.

Zhao, Changbo; Li, Guo-Zheng; Wang, Chengjun; Niu, Jinling

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.

2017-01-01

Accurate emotion recognition from speech is important for applications like smart health care, smart entertainment, and other smart services. High accuracy emotion recognition from Chinese speech is challenging due to the complexities of the Chinese language. In this paper, we explore how to improve the accuracy of speech emotion recognition, including speech signal feature extraction and emotion classification methods. Five types of features are extracted from a speech sample: mel frequency cepstrum coefficient (MFCC), pitch, formant, short-term zero-crossing rate and short-term energy. By comparing statistical features with deep features extracted by a Deep Belief Network (DBN), we attempt to find the best features to identify the emotion status for speech. We propose a novel classification method that combines DBN and SVM (support vector machine) instead of using only one of them. In addition, a conjugate gradient method is applied to train DBN in order to speed up the training process. Gender-dependent experiments are conducted using an emotional speech database created by the Chinese Academy of Sciences. The results show that DBN features can reflect emotion status better than artificial features, and our new classification approach achieves an accuracy of 95.8%, which is higher than using either DBN or SVM separately. Results also show that DBN can work very well for small training databases if it is properly designed. PMID:28737705

2002-03-01

Records of solar and lunar eclipses and occultations of stars in the Nihongi have been investigated to show their usefulness in answering questions about the long term variability of the Earth's rate of rotation. Results show that reliability of these records depend on the volume of the Nihongi and records in β group of volumes in the classification by H. Mori based on Chinese characters employed as phonetic letters, i.e. Vol. 22 (Empress Suiko), Vol. 23 (Emperor Jomei), and Vol. 29 (Emperor Tenmu), are highly reliable for these studies. Studies of solar eclipses recorded as total eclipses in the Nihongi and the Suishu and an occultation of Mars recorded in the Nihongi show that good agreements can be obtained between descriptions in these Japanese and Chinese historical books and calculations when we adopt TT-UT=3000 sec with correction for tidal term -2.0"/cy2 in the 7th century. Descriptions of solar and lunar eclipses recorded in Vol. 24 (Empress Kogyoku) and Vol. 30 (Empress Jito) are not based on observations but on theoretical predictions. All records of comets, aurorae, volcanic explosions, earthquakes, and tsunami in the Nihongi are described in β group volumes.

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.

A Machine Learning-based Method for Question Type Classification in Biomedical Question Answering.

Biomedical question type classification is one of the important components of an automatic biomedical question answering system. The performance of the latter depends directly on the performance of its biomedical question type classification system, which consists of assigning a category to each question in order to determine the appropriate answer extraction algorithm. This study aims to automatically classify biomedical questions into one of the four categories: (1) yes/no, (2) factoid, (3) list, and (4) summary. In this paper, we propose a biomedical question type classification method based on machine learning approaches to automatically assign a category to a biomedical question. First, we extract features from biomedical questions using the proposed handcrafted lexico-syntactic patterns. Then, we feed these features for machine-learning algorithms. Finally, the class label is predicted using the trained classifiers. Experimental evaluations performed on large standard annotated datasets of biomedical questions, provided by the BioASQ challenge, demonstrated that our method exhibits significant improved performance when compared to four baseline systems. The proposed method achieves a roughly 10-point increase over the best baseline in terms of accuracy. Moreover, the obtained results show that using handcrafted lexico-syntactic patterns as features' provider of support vector machine (SVM) lead to the highest accuracy of 89.40 %. The proposed method can automatically classify BioASQ questions into one of the four categories: yes/no, factoid, list, and summary. Furthermore, the results demonstrated that our method produced the best classification performance compared to four baseline systems.

Toward automated classification of consumers' cancer-related questions with a new taxonomy of expected answer types.

2016-09-01

This article examines methods for automated question classification applied to cancer-related questions that people have asked on the web. This work is part of a broader effort to provide automated question answering for health education. We created a new corpus of consumer-health questions related to cancer and a new taxonomy for those questions. We then compared the effectiveness of different statistical methods for developing classifiers, including weighted classification and resampling. Basic methods for building classifiers were limited by the high variability in the natural distribution of questions and typical refinement approaches of feature selection and merging categories achieved only small improvements to classifier accuracy. Best performance was achieved using weighted classification and resampling methods, the latter yielding an accuracy of F1 = 0.963. Thus, it would appear that statistical classifiers can be trained on natural data, but only if natural distributions of classes are smoothed. Such classifiers would be useful for automated question answering, for enriching web-based content, or assisting clinical professionals to answer questions. © The Author(s) 2015.

The purpose of this study was to compare cervical cancer knowledge and prevention strategy participation among Chinese-American women compared with Southeast-Asian-American women. We performed a cross-sectional survey of Chinese and Southeast Asian women in Rhode Island. Anonymous surveys were administered following informed consent. The survey included demographics and questions related to health care practices, cervical cancer, and the human papilloma virus (HPV). Categorical variables were compared by Fisher's exact test. Mean scores of correct answers on the knowledge questions were compared by Student's t-test and analysis of variance. Ninety-six Chinese women and 132 Southeast Asian women were included in the analysis. Sixty-seven percent of Chinese women had at least a college education compared with 37% of Southeast Asian women (p < .0001). Nineteen percent of Chinese women reported annual household incomes of greater than $100,000 compared with 3% of Southeast Asian women (p = .0003). Twenty percent of Southeast Asian women did not have health insurance compared with 10% of Chinese women (p = .06). Among both groups, 25% of participants either never had a pap test or did not know if they ever had a pap test. There was a greater lack of knowledge about the relationship between HPV and cervical cancer among Chinese (mean 2.9 out of 8 questions) compared with Southeast Asian (mean 3.6 out of 8 questions; p = .02). Regardless of ethnic subgroup, education, or income, all participants had a poor knowledge of cervical cancer and HPV. This study supports the need for improvement in cervical cancer prevention education among all Asian women. Copyright © 2014 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Despite extensive studies on cultivated rice, the genetic structure and subdivision of this crop remain unclear at both global and local scales. Using 84 nuclear simple sequence repeat markers, we genotyped a panel of 153 global rice cultivars covering all previously recognized groups and 826 cultivars representing the diversity of Chinese rice germplasm. On the basis of model-based grouping, neighbour-joining tree and principal coordinate analysis, we confirmed the widely accepted five major groups of rice cultivars (indica, aus, aromatic, temperate japonica and tropical japonica), and demonstrated that rayada rice was unique in genealogy and should be treated as a new (the sixth) major group of rice germplasm. With reference to the global classification of rice cultivars, we identified three major groups (indica, temperate japonica and tropical japonica) in Chinese rice germplasm and showed that Chinese temperate japonica contained higher diversity than that of global samples, whereas Chinese indica and tropical japonica maintained slightly lower diversity than that present in the global samples. Particularly, we observed that all seasonal, drought-tolerant and endosperm types occurred within each of three major groups of Chinese cultivars, which does not support previous claims that seasonal differentiation exists in Indica and drought-tolerant differentiation is present in Japonica. It is most likely that differentiation of cultivar types arose multiple times stemming from artificial selection for adaptation to local environments. PMID:24326293

A Method of Neighbor Classes Based SVM Classification for Optical Printed Chinese Character Recognition

2013-01-01

In optical printed Chinese character recognition (OPCCR), many classifiers have been proposed for the recognition. Among the classifiers, support vector machine (SVM) might be the best classifier. However, SVM is a classifier for two classes. When it is used for multi-classes in OPCCR, its computation is time-consuming. Thus, we propose a neighbor classes based SVM (NC-SVM) to reduce the computation consumption of SVM. Experiments of NC-SVM classification for OPCCR have been done. The results of the experiments have shown that the NC-SVM we proposed can effectively reduce the computation time in OPCCR. PMID:23536777

Phenotypic evolution of Crohn's disease occurs in whites but has never been described in other populations. The Montreal classification may describe phenotypes more precisely. The aim of this study was to validate the Montreal classification through a longitudinal sensitivity analysis in detecting phenotypic variation compared to the Vienna classification. This was a retrospective longitudinal study of consecutive Chinese Crohn's disease patients. All cases were classified by the Montreal classification and the Vienna classification for behavior and location. The evolution of these characteristics and the need for surgery were evaluated. A total of 109 patients were recruited (median follow-up: 4 years, range: 6 months-18 years). Crohn's disease behavior changed 3 years after diagnosis (P = 0.025), with an increase in stricturing and penetrating phenotypes, as determined by the Montreal classification, but was only detected by the Vienna classification after 5 years (P = 0.015). Disease location remained stable on follow-up in both classifications. Thirty-four patients (31%) underwent major surgery during the follow-up period with the stricturing [P = 0.002; hazard ratio (HR): 3.3; 95% CI: 1.5-7.0] and penetrating (P = 0.03; HR: 5.8; 95% CI: 1.2-28.2) phenotypes according to the Montreal classification associated with the need for major surgery. In contrast, colonic disease was protective against a major operation (P = 0.02; HR: 0.3; 95% CI: 0.08-0.8). This is the first study demonstrating phenotypic evolution of Crohn's disease in a nonwhite population. The Montreal classification is more sensitive to behavior phenotypic changes than is the Vienna classification after excluding perianal disease from the penetrating disease category and was useful in predicting course and the need for surgery.

Caucasian reference data are used to classify bone mineral density in US women of all races. However, use of Chinese American reference data yields lower osteoporosis prevalence in Chinese women. The reduction in osteoporosis labeling may be relevant for younger Chinese women at low fracture risk. Caucasian reference data are used for osteoporosis classification in US postmenopausal women regardless of race, including Asians who tend to have lower bone mineral density (BMD) than women of white race. This study examines BMD classification by ethnic T-scores for Chinese women. Using BMD data in a Northern California healthcare population, Chinese women aged 50-79 years were compared to age-matched white women (1:5 ratio), with femoral neck (FN), total hip (TH), and lumbar spine (LS) T-scores calculated using Caucasian versus Chinese American reference data. Comparing 4039 Chinese and 20,195 white women (44.8 % age 50-59 years, 37.5 % age 60-69 years, 17.7 % age 70-79 years), Chinese women had lower BMD T-scores at the FN, TH, and LS (median T-score 0.29-0.72 units lower across age groups, p < 0.001) using Caucasian reference data. Using Chinese American BMD reference data resulted in an average +0.47, +0.36, and +0.48 units higher FN, TH, and LS T-scores, respectively, reducing the prevalence of osteoporosis (T-score ≤ -2.5) in Chinese women at the FN (16.7 to 6.6 %), TH (9.8 to 3.2 %), and LS (23.2 to 8.9 %); osteoporosis prevalence at any one of three sites fell from 29.6 to 12.6 % (22.4 to 8.1 % for age 50-64 years and 43.2 to 21.0 % for age 65-79 years). Use of Chinese American BMD reference data yields higher (ethnic) T-scores by 0.4-0.5 units, with a large proportion of Chinese women reclassified from osteoporosis to osteopenia. The reduction in osteoporosis labeling with ethnic T-scores may be relevant for younger Chinese women at low fracture risk.

To explore a set of International Classification of Functioning, Disability and Health (ICF) categories that cover the spinal cord injury (SCI) nursing practice in China through a national expert survey. An internet-based email survey was used. An original set of ICF categories specifically for SCI nursing has been developed from the preliminary studies based on an international perspective. For cultural adaptation in China, a national expert survey was conducted with Chinese experts on SCI nursing to identify the ICF categories that were specifically for SCI nursing in China. The ICF categories which received more than 80% support from the experts would be reported. Twenty-nine Chinese experts on SCI nursing participated. There were 81 ICF categories which received more than 80% agreement among the experts, including 33 Body Functions categories, eight Body Structures, 24 Activities and Participation, six Environmental Factors and 10 Personal Factors items. A set of ICF categories that cover the SCI nursing practice in China was identified. It reflects the main issues that Chinese nurses focus on in caring SCI patients. These categories can facilitate Chinese nurses to use the ICF in multidisciplinary teamwork and improve the participation of nurses in the team. Implications for Rehabilitation In China, nurses lack of an effective model or tool to communicate with the other health professionals in the rehabilitation team for spinal cord injury (SCI) patients. International Classification of Functioning, Disability and Health (ICF) is a tool for multidisciplinary use, which can promote the communication and collaboration in the healthcare team by establishing a common language across different disciplines and sectors. This set of ICF categories developed from this study can serve as a roadmap for important items for use in clinical practice of Chinese SCI nursing.

Generation and validation of characteristic spectra from EO1 Hyperion image data for detecting the occurrence of the invasive species, Chinese tallow

USGS Publications Warehouse

Ramsey, Elijah W.; Rangoonwala, A.; Nelson, G.; Ehrlich, R.; Martella, K.

2005-01-01

Chinese tallow (Triadica sebifera) is an invasive tree that is spreading throughout the south-eastern United States and now into the west, and in many places causing extensive change to native habitat and associated wildlife. Detecting and mapping the relative distribution of this species is important to its control and eradication. To map the relative distribution of Chinese tallow within a southwestern Louisiana coastal wetland to upland environment, Earth Observing 1 (EO1) satellite Hyperion sensor hyperspectral image data were combined with a subpixel extraction method that modelled characteristic spectra from the image data without requiring a priori characteristic spectra. Because of the low percentage occurrences of Chinese tallow and high spectral covariation in the environment, unique validation and verification methods were implemented, relying on simultaneous collection of field canopy reflectance spectra and subsequent classification of canopy compositions. The subpixel extraction method produced five characteristic spectra, which we further refined to four that adequately represented the field spectra, as well as the Hyperion imaged canopy reflectance datasets. Characteristic spectra were designated as senescing foliage, cypress-tupelo trees, and trees without leaves; shadows and green vegetation; senescing Chinese tallow with yellow leaves and yellowing foliage; and senescing Chinese tallow with red leaves ('red tallow'). About 81% (n=34) of the field and 78% (n=33) of the Hyperion imaged characteristic spectra associated with 'red tallow' were explained by the compositions generated in the field slide classifications. ?? 2005 US Government.

To illustrate the solubility involved in biopharmaceutics classification system of Chinese materia medica (CMMBCS) , the influences of artificial multicomponent environment on solubility were investigated in this study. Mathematical model was built to describe the variation trend of their influence on the solubility of puerarin. Carried out with progressive levels, single component environment: baicalin, berberine and glycyrrhizic acid; double-component environment: baicalin and glycyrrhizic acid, baicalin and berberine and glycyrrhizic acid and berberine; and treble-component environment: baicalin, berberin, glycyrrhizic acid were used to describe the variation tendency of their influences on the solubility of puerarin, respectively. And then, the mathematical regression equation model was established to characterize the solubility of puerarin under multicomponent environment.

The neurocognitive profile of community-dwelling Chinese subjects with 'questionable' dementia was studied. One hundred and fifty-four ambulatory Chinese subjects were recruited from local social centers for the elderly. Each subject was examined using the Clinical Dementia Rating (CDR), the Cantonese version of the Mini-Mental State Examination (CMMSE), the Chinese version of the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog), the Category Verbal Fluency Test (CVFT), digit and visual span tests, and the Cambridge Neurological Inventory. The neurocognitive profile of nondemented subjects (CDR 0) was compared with that of subjects with 'questionable' dementia (CDR 0.5). Subjects with 'questionable' dementia were older, and had lower educational levels and global cognitive assessment scores than the controls (CMMSE and ADAS-Cog; t tests, p < 0.001). In addition, they also had significantly lower scores in delayed recall, reverse span, verbal fluency tests and worse performance in complex motor tasks related to executive function (Mann-Whitney tests, p < 0.001). Logistic regression analysis revealed that ADAS-Cog, CVFT, and reverse visual span were significant predictors for the CDR of 'questionable' dementia. Aside from memory impairment, executive function deficits were also present in subjects with 'questionable' dementia. To identify groups cognitively at risk for dementia, concomitant assessments of memory and executive function are suggested.

Obesity classification using body mass index (BMI) may miss subjects with elevated body fat percentage (BF%) and related metabolic risk factors. We aimed to evaluate whether BF% calculated by equations could provide more information about metabolic risks, in addition to BMI classification, in a cross-sectional rural Chinese population. A total of 2,990 men and women aged 18-80 years were included in this study. BF% was calculated using previously validated Chinese-specific equations. Metabolic syndrome was defined according to the updated National Cholesterol Education Program Panel III criteria for Asian Americans. In total, 33.6% men and 32.9% women were overweight/obese according to BMI classification. Among those within the normal BMI range, 25.4% men and 54.7% women were indicated as overweight or obese given their elevated BF% (men: BF% ≥ 20%; women: BF% ≥ 30%). In both men and women, compared with those with normal BMI and BF% (NBB), subjects with normal BMI but elevated BF% (NBOB) were more likely to carry abnormal serum lipid profile and to have higher risks of metabolic syndrome. The multivariable adjusted odds ratios (95% confidence intervals) for metabolic syndrome were 5.45 (2.37-9.53, P < 0.001) and 5.65 (3.36-9.52, P < 0.001) for men and women, respectively. Moreover, the women with NBOB also showed higher blood pressure and serum uric acid than women with NBB. Our study suggested that high BF% based on equations may indicate adverse metabolic profiles among rural Chinese adults with a normal BMI. © 2017 Wiley Periodicals, Inc.

Chau, Shirley; Lai, Daniel W L

2011-12-01

The present study investigated the link between the sizes of the Chinese community to the health of Chinese seniors in Canada. A secondary data analysis of survey data from a representative sample of 2,272 Chinese older adults aged 55 and over was conducted. Hierarchical regression analyses were performed to assess the effects of the size of Chinese communities in Chinese seniors' health. Chinese seniors residing in the community with a small Chinese population reported better physical and mental health than the Chinese seniors residing in communities with a larger Chinese population. The findings were contrary to expectations that health of Chinese seniors should be higher in cities with large Chinese communities. These findings raise new questions for future investigations into the dynamics and impact of ethnic community size, and the importance of studying intragroup differences within ethno-cultural groups to better understand health disparities in ethnic groups.

Chinese yew is a medicinal plant which has the largest planted area, better economic effects and ecological benefits in our country. People have insufficient appreciation of centuries-old historical document and abundant cultural connotation of Chinese yew, because Chinese yew had no name in ancient times and some expressions of western countries are still cited at present. Therefore, this paper did a great deal of analysis and reference works focusing on synonym and byname of ancient Chinese yew. Excavation and classification of historical documents of Chinese yew from ancient classics and bibliography had been done by studying 3 503 books, about billions of words been recorded in the Si Ku Quan Shu. These researches made up for simple and inadequate contents of many large tool books, like Chinese materia medica and traditional Chinese medicine, and so on. At the same time, in order to change the situation of no name, uncertain channel tropism, irregular functions of Chinese yew, its property and flavor, channel tropism, effects and functions had been summarized. History of the tumor treatment of Chinese yew had been traced back to the time of Tang Dynasty and this was almost 1 200 years earlier than western countries.

Food Therapy in Sinosphere Asia.

Chu, Natural Hoi Sing; Yao, Chu Kion; Tan, Victoria Ping Yi

2018-02-01

Traditional Chinese Food Therapy has long been an integral part of dietary practices in Sinosphere Asia. This therapy is defined by the classification of foods into cooling (Yin) and heaty (Yang) and the manipulation of dietary intake of these foods as a therapeutic strategy for chronic diseases. Both functional dyspepsia (FD) and irritable bowel syndrome (IBS) are chronic, functional gut disorders widely prevalent in Sinosphere Asia. Diet is increasingly recognized as a symptom trigger in FD and IBS, and the evidence suggesting the utility of diet therapies as front-line management is growing, particularly in the West. Specifically, a diet low in Fermentable, Oligosaccharides, Disaccharides, Monosaccharides, and Polyols is an efficacious therapy for patients with IBS. In contrast, a proportion of patients with IBS in Sinosphere Asia utilize Chinese Food Therapy for symptom management. Chinese Food Therapy provides an attractive target for integration with evidence-based Western dietary therapies as a management strategy in FD and IBS. However, significant gaps in research exist with the utility of Chinese Food Therapy that first need to be addressed. This includes a lack of standardization for heaty and cooling classification, limited mechanistic rationale or clinical studies supporting its efficacy in FD and IBS, and the lack of an ideal practitioner for implementation of Chinese Food Therapy. Hence, the review provides a summary of the role of diet and nutrition in Sinosphere Asia with an emphasis on FD and IBS, and an examination of how modern dietary practices may be able to be integrated into practices in this region.

Cultural differences in responses to a Likert scale were examined. Self-identified Chinese, Japanese, and Americans (N=136, 323, and 160, respectively) recruited at ethnic or general supermarkets in Southern California completed a 13-question Sense of Coherence scale with a choice of either four, five, or seven responses in either Chinese, Japanese, or English. The Japanese respondents more frequently reported difficulty with the scale, the Chinese more frequently skipped questions, and both these groups selected the midpoint more frequently on items that involved admitting to a positive emotion than did the Americans, who were more likely to indicate a positive emotion. Construct validity of the scale tended to be better for the Chinese and the Americans when there were four response choices and for the Japanese when there were seven. Although culture affected response patterns, the association of sense of coherence and health was positive in all three cultural groups. Copyright 2002 Wiley Periodicals, Inc.

This study aimed to evaluate survival trends for patients with gastric cancer in northeast China in the most recent three decades and analyze the applicability of the UICC tumor-node-metastasis (TNM) classification 7th edition for Chinese patients with gastric cancer. A review of all inpatient and outpatient records of patients with gastric cancer was conducted in the first hospital of China Medical University and the Liaoning Cancer Hospital and Institute. All patients who met the inclusion criteria and were seen from January 1980 through December 2009 were included in the study. The primary outcome was 5-year survival, which was analyzed according to decade of diagnosis and TNM classifications. From 1980 through 2009, the 5-year survival rates for patients with gastric cancer (n=2414) increased from 39.1% to 57.3%. Decade of diagnosis was significantly associated with patient survival (p = 0.013), and the 5-year survival rate in the 2000s was remarkably higher than that in the 1980s and 1990s (p = 0.004 and 0.049, respectively). When classified according to the UICC TNM classification of gastric cancer 7th edition, the prognoses of stage IIIA and stage IIIB patients were not significantly different (p = 0.077). However, if stage T4b and stage N0 patients were classified as stage IIIA, the prognoses of stage IIIA and stage IIIB patients were significantly different (p < 0.001). Hence, there was a significant difference in survival during the three time periods in Northeast China. Classifying stage T4b and stage N0 patients as stage IIIA according to the 7th edition of UICC gastric cancer TNM classifications better stratified Chinese patients and predicted prognoses.

The origins and authenticity against frauds are two essential aspects of food quality. In this work, a comprehensive quality evaluation method by FT-NIR spectroscopy and chemometrics were suggested to address the geographical origins and authentication of Chinese Ganoderma lucidum (GL). Classification for 25 groups of GL samples (7 common species from 15 producing areas) was performed using near-infrared spectroscopy and interval-combination One-Versus-One least squares support vector machine (IC-OVO-LS-SVM). Untargeted analysis of 4 adulterants of cheaper mushrooms was performed by one-class partial least squares (OCPLS) modeling for each of the 7 GL species. After outlier diagnosis and comparing the influences of different preprocessing methods and spectral intervals on classification, IC-OVO-LS-SVM with standard normal variate (SNV) spectra obtained a total classification accuracy of 0.9317, an average sensitivity and specificity of 0.9306 and 0.9971, respectively. With SNV or second-order derivative (D2) spectra, OCPLS could detect at least 2% or more doping levels of adulterants for 5 of the 7 GL species and 5% or more doping levels for the other 2 GL species. This study demonstrates the feasibility of using new chemometrics and NIR spectroscopy for fine classification of GL geographical origins and species as well as for untargeted analysis of multiple adulterants.

To understand Chinese immigrants' experiences with mental illness stigma and mental health disparities, we integrate frameworks of 'structural vulnerability' and 'moral experience' to identify how interaction between structural discrimination and cultural engagements might shape stigma. Fifty Chinese immigrants, including 64% Fuzhounese immigrants who experienced particularly harsh socio-economical deprivation, from two Chinese bilingual psychiatric inpatient units in New York City were interviewed from 2006 to 2010 about their experiences of mental illness stigma. Interview questions were derived from 4 stigma measures, covering various life domains. Participants were asked to elaborate their rating of measure items, and thus provided open-ended, narrative data. Analysis of the narrative data followed a deductive approach, guided by frameworks of structural discrimination and "what matters most" - a cultural mechanism signifying meaningful participation in the community. After identifying initial coding classifications, analysis focused on the interface between the two main concepts. Results indicated that experiences with mental illness stigma were contingent on the degree to which immigrants were able to participate in work to achieve "what mattered most" in their cultural context, i.e., accumulation of financial resources. Structural vulnerability - being situated in an inferior position when facing structural discrimination - made access to affordable mental health services challenging. As such, structural discrimination increased healthcare spending and interfered with financial accumulation, often resulting in future treatment nonadherence and enforcing mental health disparities. Study participants' internalizing their structurally-vulnerable position further led to a depreciated sense of self, resulting in a reduced capacity to advocate for healthcare system changes. Paradoxically, the multi-layered structural marginalization experienced by Chinese immigrants with mental illness allowed those who maintained capacity to work to retain social status even while holding a mental illness status. Mental health providers may prioritize work participation to shift service users' positions within the hierarchy of structural vulnerability. Copyright © 2013 Elsevier Ltd. All rights reserved.

Performance of the international physical activity questionnaire (short form) in subgroups of the Hong Kong chinese population

PubMed Central

2011-01-01

Background The International Physical Activity Questionnaire (IPAQ-SF) has been validated and recommended as an efficient method to assess physical activity, but its validity has not been investigated in different population subgroups. We examined variations in IPAQ validity in the Hong Kong Chinese population by six factors: sex, age, job status, educational level, body mass index (BMI), and visceral fat level (VFL). Methods A total of 1,270 adults (aged 42.9 ± SD 14.4 years, 46.1% male) completed the Chinese version of IPAQ (IPAQ-C) and wore an accelerometer (ActiGraph) for four days afterwards. The IPAQ-C and the ActiGraph were compared in terms of estimated Metabolic Equivalent Task minutes per week (MET-min/wk), minutes spent in activity of moderate or vigorous intensity (MVPA), and agreement in the classification of physical activity. Results The overall Spearman correlation (ρ) of between the IPAQ-C and ActiGraph was low (0.11 ± 0.03; range in subgroups 0.06-0.24) and was the highest among high VFL participants (0.24 ± 0.05). Difference between self-reported and ActiGraph-derived MET-min/wk (overall 2966 ± 140) was the smallest among participants with tertiary education (1804 ± 208). When physical activity was categorized into over or under 150 min/wk, overall agreement between self-report and accelerometer was 81.3% (± 1.1%; subgroup range: 77.2%-91.4%); agreement was the highest among those who were employed full-time in physically demanding jobs (91.4% ± 2.7%). Conclusions Sex, age, job status, educational level, and obesity were found to influence the criterion validity of IPAQ-C, yet none of the subgroups showed good validity (ρ = 0.06 to 0.24). IPAQ-SF validity is questionable in our Chinese population. PMID:21801461

As an important application in the field of text line recognition and office automation, Chinese character recognition has become an important subject of pattern recognition. However, due to the large number of Chinese characters and the complexity of its structure, there is a great difficulty in the Chinese character recognition. In order to solve this problem, this paper proposes a method of printed Chinese character recognition based on Gabor feature extraction and Convolution Neural Network(CNN). The main steps are preprocessing, feature extraction, training classification. First, the gray-scale Chinese character image is binarized and normalized to reduce the redundancy of the image data. Second, each image is convoluted with Gabor filter with different orientations, and the feature map of the eight orientations of Chinese characters is extracted. Third, the feature map through Gabor filters and the original image are convoluted with learning kernels, and the results of the convolution is the input of pooling layer. Finally, the feature vector is used to classify and recognition. In addition, the generalization capacity of the network is improved by Dropout technology. The experimental results show that this method can effectively extract the characteristics of Chinese characters and recognize Chinese characters.

2017-01-01

The online patient question and answering (Q&A) system, either as a website or a mobile application, attracts an increasing number of users in China. Patients will post their questions and the registered doctors then provide the corresponding answers. A large amount of questions with answers from doctors are accumulated. Instead of awaiting the response from a doctor, the newly posted question could be quickly answered by finding a semantically equivalent question from the Q&A achive. In this study, we investigated a novel deep learning based method to retrieve the similar patient question in Chinese. An unsupervised learning algorithm using deep neural network is performed on the corpus to generate the word embedding. The word embedding was then used as the input to a supervised learning algorithm using a designed deep neural network, i.e. the supervised neural attention model (SNA), to predict the similarity between two questions. The experimental results showed that our SNA method achieved P@1 = 77% and P@5 = 84%, which outperformed all other compared methods.

2010-01-01

Objectives This study sought to find answers to the following questions: 1) Can we predict whether a patient will revisit a healthcare center? 2) Can we anticipate diseases of patients who revisit the center? Methods For the first question, we applied 5 classification algorithms (decision tree, artificial neural network, logistic regression, Bayesian networks, and Naïve Bayes) and the stacking-bagging method for building classification models. To solve the second question, we performed sequential pattern analysis. Results We determined: 1) In general, the most influential variables which impact whether a patient of a public healthcare center will revisit it or not are personal burden, insurance bill, period of prescription, age, systolic pressure, name of disease, and postal code. 2) The best plain classification model is dependent on the dataset. 3) Based on average of classification accuracy, the proposed stacking-bagging method outperformed all traditional classification models and our sequential pattern analysis revealed 16 sequential patterns. Conclusions Classification models and sequential patterns can help public healthcare centers plan and implement healthcare service programs and businesses that are more appropriate to local residents, encouraging them to revisit public health centers.

2016-07-01

To understand cyber citizens' opinion accurately from Chinese news comments, the clear definition on nonsense is present, and a detection model based on logistic regression (LR) is proposed. The detection of nonsense can be treated as a binary-classification problem. Besides of traditional lexical features, we propose three kinds of features in terms of emotion, structure and relevance. By these features, we train an LR model and demonstrate its effect in understanding Chinese news comments. We find that each of proposed features can significantly promote the result. In our experiments, we achieve a prediction accuracy of 84.3% which improves the baseline 77.3% by 7%.

To investigate key factors associated with oral health-related quality of life (OHRQOL) of Hong Kong Chinese adults with orofacial pain (OFP) symptoms. A cross-sectional study was conducted amongst a random sample of registered patients at a primary medical care teaching clinic in Hong Kong. Patients who were aged 35-70 years and had experienced OFP symptoms in the past 1 month were included. The OHRQOL was assessed by the Chinese version of the Oral Health Impact Profile (OHIP-14). A structured questionnaire on OFP symptoms and characteristics in the past 1 month, the depression and non-specific physical symptoms (NPS) scale in the research diagnostic criteria for temporomandibular disorders (RDC/TMD) questionnaire, and questions about professional treatment and dental attendance were administered before a standard clinical assessment. Negative binomial regression with forward stepwise selection was used to investigate key factors associated with the OHIP-14 additive score. The mean OHIP-14 additive score of the 200 participants was 10.1 (SD 9.4). Regression analysis revealed that five independent factors were significantly associated with higher OHIP-14 additive scores (indicating a poorer OHRQOL): a higher pain scale rating in the past 1 month (p=0.001), OFP clinical classification as musculoligamentous/soft tissue (MST) or dentoalveolar (DA) instead of neurological/vascular (NV) (p<0.001), more frequent dental attendance (p=0.008), moderate/severe RDC/TMD depression (p=0.005) and moderate/severe RDC/TMD NPS with pain (p=0.003). Various factors were associated with OHRQOL and could have implications for the improvement of OHRQOL in people in the community who have OFP symptoms. Copyright © 2011 Elsevier Ltd.

Cardiovascular disease(CVD) is the leading cause of mortality among patients with type 2 diabetes mellitus(T2DM), and a risk classification model for CVD among primary care diabetic patients is pivotal for risk-based interventions and patient information. This study developed a simple tool for a 5-year CVD risk prediction for primary care Chinese patients with T2DM. A retrospective cohort study was conducted on 137,935 primary care Chinese T2DM patients aged 18-79 years without history of CVD between 1 January 2010 and 31 December 2010. New events of CVD of the cohort over a median follow up of 5 years were extracted from the medical records. A classification rule of 5-year CVD risk was obtained from the derivation cohort and validated in the validation cohort. Significant risk factors included in decision tree were age, gender, smoking status, diagnosis duration, obesity, unsatisfactory control on haemoglobin A1c and cholesterol, albuminuria and stage of chronic kidney disease, which categorized patients into five 5-year CVD risk groups(<5%; 5-9%; 10-14%; 15-19% and ≥20%). Taking the group with the lowest CVD risk, the hazard ratios varied from 1.92(1.77,2.08) to 8.46(7.75,9.24). The present prediction model performed comparable discrimination and better calibration from the plot compared to other current existing models.

Traditional Chinese medicine (TCM), Japanese-Chinese medicine, and Korean Sasang constitutional medicine have common origins. However, the constitutional medicines of China, Japan, and Korea differ because of the influence of geographical culture, social environment, national practices, and other factors. This paper aimed to compare the constitutional medicines of China, Japan, and Korea in terms of theoretical origin, constitutional classification, constitution and pathogenesis, clinical applications and basic studies that were conducted. The constitutional theories of the three countries are all derived from the Canon of Internal Medicine or Treatise on Febrile and Miscellaneous Diseases of Ancient China. However, the three countries have different constitutional classifications and criteria. Medical sciences in the three countries focus on the clinical applications of constitutional theory. They all agree that different pathogenic laws that guide the treatment of diseases govern different constitutions; thus, patients with different constitutions are treated differently. The three countries also differ in terms of drug formulations and medication. Japanese medicine is prescribed only based on constitution. Korean medicine is based on treatment, in which drugs cannot be mixed. TCM synthesize the treatment model of constitution differentiation, disease differentiation and syndrome differentiation with the treatment thought of treating disease according to three categories of etiologic factors, which reflect the constitution as the characteristic of individual precision treatment. In conclusion, constitutional medicines of China, Japan, and Korea have the same theoretical origin, but differ in constitutional classification, clinical application of constitutional theory on the treatment of diseases, drug formulations and medication.

The solubility and permeability on four kinds of flavonoids (kaempferol, hesperidin, apigenin, genistein) were test according to the theory of biopharmaceutics classification system (BCS), and their absorption mechanism. The solubility was investigated by the method in determination of solubility of "Chinese Pharmacopoeia 2010". To detect appearance permeability of compounds mentioned above, the appropriate concentrations were selected by the MTT method in cell transfer experiments in Caco-2 cell model, which established by in vitro cell culture method. Therefore, these compounds were classified with BCS according to solubility and permeability. In addition, to explore absorption mechanisms, the experiments in three different concentrations of compounds in high, medium and low in bidirectional transformation methods in Caco-2 cell model contacted. The study indicated that all of kaempferol, hesperidin, apigenin, genistein have the characteristics in low solubility and high permeability, which belong to BCSⅡ, and the absorption mechanism of kaempferol was active transportation. Whereas, hesperidin, apigenin, genistein were passive transportation. In this study, it carried out initial explorations on establishment of determination for solubility and permeability in flavonoids, and provided theoretical reference for further research on BCS in traditional Chinese medicine.

This study aims to develop and validate a Chinese translation of the 6-item De Jong Gierveld Loneliness Scale - a widely used instrument to measure loneliness - specifically determining its psychometric properties in community-dwelling Chinese elders in Hong Kong. The relationships between loneliness and several clinical variables are also assessed. The English version was translated into Chinese. Content validity was established by group discussion and Delphi panel. The questionnaire was administered to 103 Hong Kong Chinese community-dwelling elders. Statistical analysis was performed to test the reliability and validity of the scale. The content validity was high as shown by the results of the Delphi panel. Cronbach's alpha of the 6-item scale was 0.76. For the inter-rater reliability of the six items, the intra-class correlation coefficients ranged from 0.98 to 1.00. The emotional loneliness subscale significantly correlated with the social loneliness subscale (rho = 0.37; p < 0.001). In using a direct question to measure loneliness, 21 participants (20%) reported that they were lonely. The overall loneliness scale score significantly correlated with the answers on the direct question of loneliness (rpb = 0.71; p < 0.001). The overall loneliness score showed significant correlation with Cornell Scale for Depression in Dementia (rho = 0.29; p = 0.003), current smoking status (rpb = 0.24; p = 0.014), and some objective social characteristics. The Chinese version of the 6-item De Jong Gierveld Loneliness Scale is a reliable and valid measure of loneliness in Chinese elders.

2016-09-01

Previous studies have documented disparities in total joint arthroplasty (TJA) utilization among African American and Hispanic patients, but utilization among non-English-speaking Chinese patients in the United States has not been studied. To quantify the utilization rate and detect ethnic factors effecting TJA utilization in non-English-speaking Chinese patients, data were gathered prospectively from the practice of a single fellowship-trained Caucasian surgeon from October 2012 to February 2013. A customized survey was drafted and validated in collaboration with a social scientist. Questions assessed demography, lifestyle factors, socioeconomic status, language skills, cultural beliefs, and prior experience with surgery. Surveys were administered in patients' native language and were collected in a blinded fashion. Overall, 269 patients were surveyed (157 Caucasian and 65 Chinese), 85 of which were recommended surgery (42 Caucasian and 26 Chinese). Seventy-six percent of Caucasian patients elected surgery, compared to 35% of Chinese patients. A multivariate logistic regression showed Chinese ethnicity to be a significant predictor of surgical decision after controlling for age, gender, socioeconomic status, and education. Several questions drafted to detect cultural differences in the aforementioned 6 categories were answered significantly differently (P < .05, chi-square). Language, lack of familiarity with surgery, lack of TJA knowledge, family members' role in decision making, and preference for a doctor of the same race may contribute to decreased utilization of TJA in this population. We believe a better understanding of the cultural beliefs and behaviors of Chinese patients will help physicians provide more optimal care to this patient population. Copyright © 2016 Elsevier Inc.

Botanical Drug Products promulgated by the US FDA could guide industry sponsors to develop herbal drugs, which was also an important reference for investigating Chinese herbal medicines. This paper reviews and discusses novel approaches for how to assess systemic exposure and pharmacokinetic of Chinese herbal medicines, which were in line with FDA guidance. This mainly focus on identifying pharmacokinetic markers of botanical products, integral pharmacokinetic study of multiple components, Biopharmaceutics drug disposition classification system, and population pharmacokinetic-pharmacodynamic study in herb-drug interaction.

Some recommendations to assess depression in Chinese people in Australasia.

PubMed

Chan, Bibiana; Parker, Gordon

2004-03-01

To provide some general recommendations for psychiatric assessment of depression among Chinese patients within a predominately Western society. A literature review is provided with interpretive comments. The prevalence of depression reported in community studies undertaken in Chinese communities is very low. To what extent Chinese people experience and seek help for depression, and how they report depressive symptoms have long been topics of some importance. The impact of acculturation as well as concepts and interpretations of illness in traditional Chinese medicine are discussed. Awareness of sensitive issues and practices within the Chinese culture will facilitate communication between medical professionals and patients, resulting in more accurate identification and diagnosis of depressive disorders. Direct but culturally sensitive and empathic questioning of psychological symptoms is needed to unveil patients' explanatory models, as most Chinese initially nominate only somatic symptoms to health practitioners. Successfully treated patients can promote earlier and wider utilization of mental health services to other Chinese people.

2014-01-01

We investigated eleven particle-size distribution (PSD) models to determine the appropriate models for describing the PSDs of 16349 Chinese soil samples. These data are based on three soil texture classification schemes, including one ISSS (International Society of Soil Science) scheme with four data points and two Katschinski's schemes with five and six data points, respectively. The adjusted coefficient of determination r (2), Akaike's information criterion (AIC), and geometric mean error ratio (GMER) were used to evaluate the model performance. The soil data were converted to the USDA (United States Department of Agriculture) standard using PSD models and the fractal concept. The performance of PSD models was affected by soil texture and classification of fraction schemes. The performance of PSD models also varied with clay content of soils. The Anderson, Fredlund, modified logistic growth, Skaggs, and Weilbull models were the best.

Objective: To investigate the present situation of diagnosis and treatment for primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG) and awareness of the relevant progress among Chinese ophthalmologists. Methods: This study was a cross-sectional, non-randomized sampling survey. Participants were ophthalmologists who attended the 11st Chinese Glaucoma Society Congress during November 11 to 12, 2016. They were invited to fill out a questionnaire. The questionnaire included participants' basic information and their knowledge about glaucoma diagnosis and treatment. The data collected through questionnaire were analyzed with SAS9.4. Results: A total of 450 questionnaires were distributed and 372 valid questionnaires were retrieved, with a response rate of 82. 7%(372/450). ISGEO classification system was adopted by 58.9% (219/372) of the participants as the diagnostic criteria for PACG. Of the respondents, 48.1% (179/372) of the participants believed that "anterior chamber angle closure mechanism-based PACG classification system" was more instructive for treatment, the percentage was higher than ISGEO classification system (42.2%, 157/372). Most (72.3%, 269/372) of the participants knew the 3-minute dark room prone test, but only 27.7%(103/372) of them applied it in clinical practice. A total of 83.4%(310/372) of the participants believed that low cerebrospinal fluid pressure is a risk factor for POAG. In all, 71.8% (267/372) of the participants reported that their institutes had applied compound trabeculectomy with adjustable suture, with 76.9%(286/372) of the participants agreeing that the adjustable suture reduced the rate of complications after trabeculectomy. Conclusions: Currently, both ISGEO classification system and anterior chamber angle closure mechanism-based PACG classification system were adopted in the diagnosis and treatment of glaucoma. Low cerebrospinal fluid pressure as new risk factors for POAG has been widely acknowledged and given attentions by Chinese ophthalmologists. The 3-minute darkroom prone test and compound trabeculectomy with adjustable suture still need to be promoted. (Chin J Ophthalmol, 2017, 53: 115-120) .

Liu, Changhua; Gu, Man

2011-06-01

With the development of the knowledge economy, knowledge has become one of the most important resources for social progress and economic development. Some countries have proposed measures for the protection of their own traditional knowledge. Traditional Chinese medicine belongs to the category of intangible cultural heritage because it is an important part of Chinese cultural heritage. Today the value of traditional knowledge of Chinese medicine has been widely recognized by the domestic and international public. This paper discusses the definition of traditional knowledge of Chinese medicine and its protection, and evaluates research on its classification. We review the present status of the protection of traditional knowledge of Chinese medicine and tentatively put forward some possible ideas and methods for the protection of traditional knowledge of Chinese medicine. Our goal is to find a way to strengthen the vitality of traditional Chinese medicine and consolidate its foundation. We believe that if we could establish a suitable sui generis(sui generis is a Latin term meaning "of its own kind" and is often used in discussions about protecting the rights of indigenous peoples. Here we use it to emphasize the fact that protection of traditional knowledge of Chinese medicine cannot be achieved through existing legal means of protection alone due to its unique characteristics) system for traditional knowledge, a more favorable environment for the preservation and development of traditional Chinese medicine will ultimately be created.

In recent years, the proportion of traditional Chinese medicine in scientific research and its clinical use increased gradually. The research result also becomes more and more valuable, but in the process of using traditional Chinese medicine, it also needs to pay more attention. With the gradual deepening of the toxicity of traditional Chinese medicine, some traditional Chinese medicines have also been found to have the potential toxicity, with the exception of some traditional toxicity Chinese medicine. Traditional Chinese medicine in the growth, processing, processing, transportation and other aspects of pollution or deterioration will also cause the side effects to the body. Clinical practice should be based on the theory of traditional Chinese medicine to guide rational drug use and follow the symptomatic medication, the principle of proper compatibility. The constitution of the patients are different, except for a few varieties of traditional Chinese medicines are natural herbs with hepatotoxicity, liver toxicity of most of the traditional Chinese medicine has idiosyncratic features. The liver plays an important role in drug metabolism. It is easy to be damaged by drugs. Therefore, the study of traditional Chinese medicine potential liver toxicity and its toxic components has become one of the basic areas of traditional Chinese medicine research. Based on the review of the literatures, this paper summarizes the clinical classification of liver toxicity, the pathogenesis of target cell injury, and systematically summarizes the mechanism of liver toxicity and toxic mechanism of traditional Chinese medicine. This paper provided ideas for the study of potential liver toxicity of traditional Chinese medicine and protection for clinical safety of traditional Chinese medicine.

This study explores the development of free will beliefs across cultures. Sixty-seven Chinese 4- and 6-year-olds were asked questions to gauge whether they believed that people could freely choose to inhibit or act against their desires. Responses were compared to those given by the U.S. children in Kushnir, Gopnik, Chernyak, Seiver, and Wellman (). Results indicate that children from both cultures increased the amount of choice they ascribed with age. For inhibition questions, Chinese children ascribed less choice than the U.S. children. Qualitative explanations revealed that the U.S. children were also more likely to endorse notions of autonomous choice. These findings suggest both cultural differences and similarities in free will beliefs. © 2016 The Authors. Child Development © 2016 Society for Research in Child Development, Inc.

Antioxidant activity of 45 Chinese herbs and the relationship with their TCM characteristics

PubMed Central

Banbury, Linda K.; Leach, David N.

2008-01-01

Here, 45 Chinese herbs that regulate blood circulation were analyzed for antioxidant activity using the oxygen radical absorbance capacity (ORAC) assay. A recent publication by Ou et al. identified a close relationship between in vitro antioxidant activity and classification of Chinese herbs as yin or yang. The 45 Chinese herbs in this study could be assigned the traditional characteristics of natures (cold, cool, hot and warm), flavors (pungent, sweet, sour, bitter and salty) and functions (arresting bleeding, promoting blood flow to relieve stasis, nourishing blood and clearing away heat from blood). These characteristics are generalized according to the theory of yin and yang. We identified a broad range, 40–1990 µmol Trolox Equivalent/g herbs, of antioxidant activity in water extracts. There was no significant correlation between ORAC values and natures or functions of the herbs. There was a significant relationship between flavors and ORAC values. Bitter and/or sour herbs had the highest ORAC values, pungent and/or sweet herbs the lowest. Other flavors had intermediate values. Flavors also correspond with the yin/yang relationship and our results are supportive of the earlier publication. We reported for the first time antioxidant properties of many Chinese herbs. High antioxidant herbs were identified as Spatholobus suberectus vine (1990 µmol TE/g), Sanguisorba officinalis root (1940 µmol TE/g), Agrimonia pilosa herb (1440 µmol TE/g), Artemisia anomala herb (1400 µmol TE/g), Salvia miltiorrhiza root (1320 µmol TE/g) and Nelembo nucifera leaf (1300 µmol TE/g). Antioxidant capacity appears to correlate with the flavors of herbs identified within the formal TCM classification system and may be a useful guide in describing their utility and biochemical mechanism of action.

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.

The accurate classification of tree species is critical for the management of forest ecosystems, particularly subtropical forests, which are highly diverse and complex ecosystems. While airborne Light Detection and Ranging (LiDAR) technology offers significant potential to estimate forest structural attributes, the capacity of this new tool to classify species is less well known. In this research, full-waveform metrics were extracted by a voxel-based composite waveform approach and examined with a Random Forests classifier to discriminate six subtropical tree species (i.e., Masson pine (Pinus massoniana Lamb.)), Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), Slash pines (Pinus elliottii Engelm.), Sawtooth oak (Quercus acutissima Carruth.) and Chinese holly (Ilex chinensis Sims.) at three levels of discrimination. As part of the analysis, the optimal voxel size for modelling the composite waveforms was investigated, the most important predictor metrics for species classification assessed and the effect of scan angle on species discrimination examined. Results demonstrate that all tree species were classified with relatively high accuracy (68.6% for six classes, 75.8% for four main species and 86.2% for conifers and broadleaved trees). Full-waveform metrics (based on height of median energy, waveform distance and number of waveform peaks) demonstrated high classification importance and were stable among various voxel sizes. The results also suggest that the voxel based approach can alleviate some of the issues associated with large scan angles. In summary, the results indicate that full-waveform LIDAR data have significant potential for tree species classification in the subtropical forests.

Assessing physician needs to develop continuing medical education (CME) activities is an integral part of CME curriculum development. The purpose of the present study was to demonstrate the feasibility of identifying areas of perceived greatest needs for continuing medical education (CME) by using questions collected electronically at the point of care. This study is a secondary analysis of the "Just-in-Time" (JIT) information librarian consultation service database of questions using quantitative content analysis methods. The original JIT project demonstrated the feasibility of a real-time librarian service for answering questions asked by primary care clinicians at the point of care using a Web-based platform or handheld device. Data were collected from 88 primary care practitioners in Ontario, Canada, from October 2005 to April 2006. Questions were answered in less than 15 minutes, enabling clinicians to use the answer during patient encounters. Description of type and frequency of questions asked, including the organ system on which the questions focused, was produced using 2 classification systems, the "taxonomy of generic clinical questions" (TGCQ), and the International Classification for Primary Care version 2 (ICPC-2). Of the original 1889 questions, 1871 (99.0%) were suitable for analysis. A total of 970 (52%) of questions related to therapy; of these, 671 (69.2%) addressed questions about drug therapy, representing 36% of all questions. Questions related to diagnosis (24.8%) and epidemiology (13.5%) were also common. Organ systems questions concerning musculoskeletal, endocrine, skin, cardiac, and digestive systems were asked more than other categories. Questions collected at the point of care provide a valuable and unique source of information on the true learning needs of practicing clinicians. The TGCQ classification allowed us to show that a majority of questions had to do with treatment, particularly drug treatment, whereas the use of the ICPC-2 classification illustrated the great variety of questions asked about the diverse conditions encountered in primary care. It is feasible to use electronically collected questions asked by primary care clinicians in clinical practice to categorize self-identified knowledge and practice needs. This could be used to inform the development of future learning activities.

This study was conducted to provide ratings of valence/pleasantness, arousal/excitement, and threat/potential harm for 160 Chinese words. The emotional valence classification (positive, negative, or neutral) of all of the words corresponded to that of the equivalent English language words. More than 90% of the participants, junior high school students aged between 12 and 17 years, understood the words. The participants were from both mainland China and Hong Kong, thus the words can be applied to adolescents familiar with either simplified (e.g. in mainland China) or traditional Chinese (e.g. in Hong Kong) with a junior secondary school education or higher. We also established eight words with negative valence, high threat, and high arousal ratings to facilitate future research, especially on attentional and memory biases among individuals prone to anxiety. Thus, the new emotional word list provides a useful source of information for affective research in the Chinese language. PMID:26226604

English and Chinese are two of the most widely used primary languages in the world. Patients in many cancer centers have a variety of ethnic backgrounds and primary languages. The comparability of version 4 of the English and Chinese versions of the Functional Assessment of Cancer Therapy-General (FACT-G) and version 3 of the European Organization for the Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) have not been established. In total, 1136 ethnic Chinese patients with cancer were recruited from the National Cancer Centre of Singapore. Patients chose to answer an English or Chinese questionnaire, according to their own preference. Multiple regression analysis was used to adjust for differences in demographic and health characteristics. Equivalence was confirmed if the 90% confidence intervals of the adjusted mean difference fell completely within an equivalence zone of +/- 0.25 standard deviations (SD). The English and Chinese versions of the Total, Emotional, and Functional Well Being Scales of the FACT-G and the Physical and Emotional Functioning Scales of the EORTC QLQ-C30 were equivalent. Scores for the other scales on the two questionnaires, at most, had a small differences that did not exceed 0.5 SD. Nevertheless, the Chinese translation of the question "I have a lack of energy" in the Physical Well Being Scale of the FACT-G produced results that differed from the results produced by the original English version. Data collected from English-speaking and Chinese-speaking respondents were capable of being pooled, and either version could be used for bilingual respondents. Nevertheless, the authors recommend modification of the Physical Well Being question that produced different results ("I have a lack of energy").

To examine the applicability of an Australian casemix classification system to the description of Chinese hospital activity. A total of 161,478 inpatient episodes from three Chengdu hospitals with demographic, diagnosis, procedure and billing data for the year 1998/1999, 1999/2000 and 2000/2001 were grouped using the Australian refined-diagnosis related groups (AR-DRGs) (version 4.0) grouper. Reduction in variance (R2) and coefficient of variation (CV). Untrimmed reduction in variance (R2) was 0.12 and 0.17 for length of stay (LOS) and cost respectively. After trimming, R2 values were 0.45 and 0.59 for length of stay and cost respectively. The Australian refined DRGs provide a good basis for developing a Chinese grouper.

2011-01-01

To determine whether the automatic classification of documents can be useful in systematic reviews on medical topics, and specifically if the performance of the automatic classification can be enhanced by using the particular protocol of questions employed by the human reviewers to create multiple classifiers. The test collection is the data used in large-scale systematic review on the topic of the dissemination strategy of health care services for elderly people. From a group of 47,274 abstracts marked by human reviewers to be included in or excluded from further screening, we randomly selected 20,000 as a training set, with the remaining 27,274 becoming a separate test set. As a machine learning algorithm we used complement naïve Bayes. We tested both a global classification method, where a single classifier is trained on instances of abstracts and their classification (i.e., included or excluded), and a novel per-question classification method that trains multiple classifiers for each abstract, exploiting the specific protocol (questions) of the systematic review. For the per-question method we tested four ways of combining the results of the classifiers trained for the individual questions. As evaluation measures, we calculated precision and recall for several settings of the two methods. It is most important not to exclude any relevant documents (i.e., to attain high recall for the class of interest) but also desirable to exclude most of the non-relevant documents (i.e., to attain high precision on the class of interest) in order to reduce human workload. For the global method, the highest recall was 67.8% and the highest precision was 37.9%. For the per-question method, the highest recall was 99.2%, and the highest precision was 63%. The human-machine workflow proposed in this paper achieved a recall value of 99.6%, and a precision value of 17.8%. The per-question method that combines classifiers following the specific protocol of the review leads to better results than the global method in terms of recall. Because neither method is efficient enough to classify abstracts reliably by itself, the technology should be applied in a semi-automatic way, with a human expert still involved. When the workflow includes one human expert and the trained automatic classifier, recall improves to an acceptable level, showing that automatic classification techniques can reduce the human workload in the process of building a systematic review.

Perception of intonation in Mandarin Chinese.

PubMed

Yuan, Jiahong

2011-12-01

There is a tendency across languages to use a rising pitch contour to convey question intonation and a falling pitch contour to convey a statement. In a lexical tone language such as Mandarin Chinese, rising and falling pitch contours are also used to differentiate lexical meaning. How, then, does the multiplexing of the F(0) channel affect the perception of question and statement intonation in a lexical tone language? This study investigated the effects of lexical tones and focus on the perception of intonation in Mandarin Chinese. The results show that lexical tones and focus impact the perception of sentence intonation. Question intonation was easier for native speakers to identify on a sentence with a final falling tone and more difficult to identify on a sentence with a final rising tone, suggesting that tone identification intervenes in the mapping of F(0) contours to intonational categories and that tone and intonation interact at the phonological level. In contrast, there is no evidence that the interaction between focus and intonation goes beyond the psychoacoustic level. The results provide insights that will be useful for further research on tone and intonation interactions in both acoustic modeling studies and neurobiological studies. © 2011 Acoustical Society of America

More mental health services are adopting the recovery paradigm. This study adds to prior research by (a) using measures of stages of recovery and elements of recovery that were designed and validated in a non-Western, Chinese culture and (b) testing which demographic factors predict advanced recovery and whether placing importance on certain elements predicts advanced recovery. We examined recovery and factors associated with recovery among 75 Hong Kong adults who were diagnosed with schizophrenia and assessed to be in clinical remission. Data were collected on socio-demographic factors, recovery stages and elements associated with recovery. Logistic regression analysis was used to identify variables that could best predict stages of recovery. Receiver operating characteristic curves were used to detect the classification accuracy of the model (i.e. rates of correct classification of stages of recovery). Logistic regression results indicated that stages of recovery could be distinguished with reasonable accuracy for Stage 3 ('living with disability', classification accuracy = 75.45%) and Stage 4 ('living beyond disability', classification accuracy = 75.50%). However, there was no sufficient information to predict Combined Stages 1 and 2 ('overwhelmed by disability' and 'struggling with disability'). It was found that having a meaningful role and age were the most important differentiators of recovery stage. Preliminary findings suggest that adopting salient life roles personally is important to recovery and that this component should be incorporated into mental health services. © The Author(s) 2014.

Using data of 200, 522, 572, and 287 Chinese from Australia, China, Hong Kong and Taiwan respectively, this study aimed at comparing the mental health literacy of Chinese people from different communities, and between Chinese communities and the Australian general public. The participants were asked questions that assessed their recognition of depression and schizophrenia. Compared with the Australians, much lower percentages of Chinese in the four Chinese communities could correctly identify depression and early schizophrenia. Commonalities in the preference for 'psychiatrist', 'psychologist', 'Chinese medical doctor', and 'Chinese traditional healer', a lack of knowledge of medications, and a higher likelihood of endorsement of traditional Chinese medicines were found among the four Chinese communities. Differences in the preference for 'general practitioner' and 'social worker', and a higher percentage of endorsement of herbal medicines were observed among the different Chinese communities. Cultural factors such as Chinese perceptions of mental illness, and socio-contextual factors such as differences in mental health care system in the four communities were offered to explain these commonalities and differences. Mental health promotion programmes for Chinese people may need to consider the above-mentioned cultural and socio-contextual factors so that specific promotion programmes can be developed.

Ex-situ conservation is an important means to protect biological genetic resources. Resource protection has received more and more attention with the continuous improvement of the comprehensive utilization of traditional Chinese medicine resources. In this paper, the research and compilation of the species list of ex-situ cultivated medicinal plants in 12 Chinese Academy of Sciences botanic gardens and 19 specialized medicinal botanic gardens in China were carried out. Based on the Species 2000(2017) and other classification databases, species diversity of medicinal plants ex-situ cultivated in these botanical gardens were analyzed. The study found that there were 16 351 higher plant species in our country, belonging to 276 families and 1 936 genera. Of these, 6 949 specieswere medicinal plants, accounting for 50.4% of the total medicinal plants. There were 1 280 medicinal plants were in threatened status, accounting for 19.6% of all threatened species in the Chinese Biodiversity Red List, with ex-situ cultivated proportion of 59.5%. And 3 988 medicinal plants were Chinese endemic species, accounting for 22.5% of all Chinese endemic species, with ex-situ cultivated proportion of 53.3%. This article has reference significance for the management and protection of medicinal plant resources. Copyright© by the Chinese Pharmaceutical Association.

Simple-random-sampling-based multiclass text classification algorithm.

2014-01-01

Multiclass text classification (MTC) is a challenging issue and the corresponding MTC algorithms can be used in many applications. The space-time overhead of the algorithms must be concerned about the era of big data. Through the investigation of the token frequency distribution in a Chinese web document collection, this paper reexamines the power law and proposes a simple-random-sampling-based MTC (SRSMTC) algorithm. Supported by a token level memory to store labeled documents, the SRSMTC algorithm uses a text retrieval approach to solve text classification problems. The experimental results on the TanCorp data set show that SRSMTC algorithm can achieve the state-of-the-art performance at greatly reduced space-time requirements.

To treat patients with vascular mild cognitive impairment (VMCI) using traditional Chinese medicine (TCM), it is necessary to classify the patients into TCM syndrome types and to apply different treatments to different types. In this paper, we investigate how to properly carry out the classification for patients with VMCI aged 50 or above using a novel data-driven method known as latent tree analysis (LTA). A cross-sectional survey on VMCI was carried out in several regions in Northern China between February 2008 and February 2012 which resulted in a data set that involves 803 patients and 93 symptoms. LTA was performed on the data to reveal symptom co-occurrence patterns, and the patients were partitioned into clusters in multiple ways based on the patterns. The patient clusters were matched up with syndrome types, and population statistics of the clusters are used to quantify the syndrome types and to establish classification rules. Eight syndrome types are identified: Qi deficiency, Qi stagnation, Blood deficiency, Blood stasis, Phlegm-dampness, Fire-heat, Yang deficiency, and Yin deficiency. The prevalence and symptom occurrence characteristics of each syndrome type are determined. Quantitative classification rules are established for determining whether a patient belongs to each of the syndrome types. A solution for the TCM syndrome classification problem for patients with VMCI and aged 50 or above is established based on the LTA of unlabeled symptom survey data. The results can be used as a reference in clinic practice to improve the quality of syndrome differentiation and to reduce diagnosis variances across physicians. They can also be used for patient selection in research projects aimed at finding biomarkers for the syndrome types and in randomized control trials aimed at determining the efficacy of TCM treatments of VMCI.

2015-10-05

To evaluate the technical characteristics and application of mass casualty incident (MCI) primary triage (PT) methods applied in China. Chinese literature was searched by Chinese Academic Journal Network Publishing Database (founded in June 2014). The English literature was searched by PubMed (MEDLINE) (1950 to June 2014). We also searched Official Websites of Chinese Central Government's (http://www.gov.cn/), National Health and Family Planning Commission of China (http://www.nhfpc.gov.cn/), and China Earthquake Information (http://www.csi.ac.cn/). We included studies associated with mass casualty events related to China, the PT applied in China, guidelines and standards, and application and development of the carding PT method in China. From 3976 potentially relevant articles, 22 met the inclusion criteria, 20 Chinese, and 2 English. These articles included 13 case reports, 3 retrospective analyses of MCI, two methods introductions, three national or sectoral criteria, and one simulated field testing and validation. There were a total of 19 kinds of MCI PT methods that have been reported in China from 1950 to 2014. In addition, there were 15 kinds of PT methods reported in the literature from the instance of the application. The national and sectoral current triage criteria are developed mainly for earthquake relief. Classification is not clear. Vague criteria (especially between moderate and severe injuries) operability are not practical. There are no triage methods and research for children and special populations. There is no data and evidence supported triage method. We should revise our existing classification and criteria so it is clearer and easier to be grasped in order to build a real, practical, and efficient PT method.

The role of features and configural processing in face-race classification

PubMed Central

Zhao, Lun; Bentin, Shlomo

2011-01-01

We explored perceptual factors that might account for the other-race classification advantage (ORCA) in classifying faces by race. Testing Chinese participants in China and Israeli participants in Israel we show that: (a) The distinction between Chinese and Israeli faces is highly accurate even on the basis of isolated eyes or faces with eyes concealed, but full faces are categorized faster. (b) The ORCA is similarly robust for full faces and for face parts. (c) The ORCA was larger when the configuration of the inner-face components was distorted, reflecting delayed categorization of own-race distorted faces relative to own-race normally configured faces but no conspicuous distortion effect on other-race faces. These data demonstrate that perceptual factors can account for the ORCA independently of social bias. We suggest that one source of the ORCA in race categorization is the configural analysis applied by default while processing own-race but not other-race faces. PMID:22008980

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

Non-scientific classification of Chinese herbal medicine as dietary supplement.

PubMed

Bao, Kexin

2017-03-01

This article focuses the category status of Chinese herbal medicine in the United States where it has been mistakenly classifified as a dietary supplement. According to Yellow Emperor Canon of Internal Medicine (Huang Di Nei Jing), clinical treatment in broad sense is to apply certain poisonous medicines to fight against pathogeneses, by which all medicines have certain toxicity and side effect. From ancient times to modern society, all, or at least most, practitioners have used herbal medicine to treat patients' medical conditions. The educational curriculums in Chinese medicine (CM) comprise the courses of herbal medicine (herbology) and herbal formulae. The objective of these courses is to teach students to use herbal medicine or formulae to treat disease as materia medica. In contrast, dietary supplements are preparations intended to provide nutrients that are missing or are not consumed in suffificient quantity in a person's diet. In contrast, Chinese herbs can be toxic, which have been proven through laboratory research. Both clinical practice and research have demonstrated that Chinese herbal medicine is a special type of natural materia medica, not a dietary supplement.

Molecular Analysis of Chinese Celastrus and Tripterygium and Implications in Medicinal and Pharmacological Studies

Celastrus and Tripterygium species, which are used in traditional Chinese medicine, have attracted much attention due to their anti-tumor promoting and neuroprotective activities, in addition to their applications in autoimmune disorders. However, systematic relationships between them and among species are unclear, and it may disturb their further medicinal utilization. In the present study, the molecular analysis of combined chloroplast and nuclear markers of all Chinese Celastrus and Tripterygium was performed, and clear inter- and intra-genus relationships were presented. The result suggests that Tripterygium constitute a natural monophyletic clade within Celastrus with strong support value. Fruit and seed type are better than inflorescence in subgeneric classification. Chinese Celastrus are classified for three sections: Sect. Sempervirentes (Maxim.) CY Cheng & TC Kao, Sect. Lunatus XY Mu & ZX Zhang, sect. nov., and Sect. Ellipticus XY Mu & ZX Zhang, sect. nov. The phylogenetic data was consistent with their chemical components reported previously. Owing to the close relationship, several evergreen Celastrus species are recommended for chemical and pharmacological studies. Our results also provide reference for molecular identification of Chinese Celastrus and Tripterygium. PMID:28081198

Chinese philosophy has been a major cornerstone of Chinese culture for millennia and has bestowed on the world traditions such as Taoism, Yin and Yang, and filial piety. Although these beliefs have remained steadfast over thousands of years, their ability to survive unchanged in the future is uncertain. As the world forges ahead into the 21st century, several pertinent questions arise: Will age-old axioms, primarily those concerning elderly Chinese and their relationship with their children, survive? When ancient, traditional beliefs conflict with newer, Western ideas, which system of thought is likely to be the victor? Moreover, will elderly Chinese Americans and their perceptions concerning long-term care facilities cause problems with the traditional familial unit? This article will discuss these issues in detail.

2014-01-01

Classification methods used in microarray studies for gene expression are diverse in the way they deal with the underlying complexity of the data, as well as in the technique used to build the classification model. The MAQC II study on cancer classification problems has found that performance was affected by factors such as the classification algorithm, cross validation method, number of genes, and gene selection method. In this paper, we study the hypothesis that the disease under study significantly determines which method is optimal, and that additionally sample size, class imbalance, type of medical question (diagnostic, prognostic or treatment response), and microarray platform are potentially influential. A systematic literature review was used to extract the information from 48 published articles on non-cancer microarray classification studies. The impact of the various factors on the reported classification accuracy was analyzed through random-intercept logistic regression. The type of medical question and method of cross validation dominated the explained variation in accuracy among studies, followed by disease category and microarray platform. In total, 42% of the between study variation was explained by all the study specific and problem specific factors that we studied together.

2016-01-01

This study aims to demonstrate the feasibility for classifying kiwifruit into shape grades by adding a single camera to current Chinese sorting lines equipped with weight sensors. Image processing methods are employed to calculate fruit length, maximum diameter of the equatorial section, and projected area. A stepwise multiple linear regression method is applied to select significant variables for predicting minimum diameter of the equatorial section and volume and to establish corresponding estimation models. Results show that length, maximum diameter of the equatorial section and weight are selected to predict the minimum diameter of the equatorial section, with the coefficient of determination of only 0.82 when compared to manual measurements. Weight and length are then selected to estimate the volume, which is in good agreement with the measured one with the coefficient of determination of 0.98. Fruit classification based on the estimated minimum diameter of the equatorial section achieves a low success rate of 84.6%, which is significantly improved using a linear combination of the length/maximum diameter of the equatorial section and projected area/length ratios, reaching 98.3%. Thus, it is possible for Chinese kiwifruit sorting lines to reach international standards of grading kiwifruit on fruit shape classification by adding a single camera. PMID:27376292

In 2011 the Chinese leadership in rehabilitation, in collaboration with the International Classification of Functioning, Disability and Health (ICF) Research Branch, embarked on an effort towards the system-wide implementation of the ICF in the healthcare system in China. We report here on the lessons learned from the pilot phase of testing the ICF Generic Set, a parsimonious set of 7 ICF categories, which have been shown to best describe functioning across the general population and people with various health conditions, for use in routine clinical practice in China. The paper discusses whether classification and measurement are compatible, what number of ICF categories should be included in data collection in routine practice, and the usefulness of a functioning profile and functioning score in clinical practice and health research planning. In addition, the paper reflects on the use of ICF qualifiers in a rating scale and the particularities of certain ICF categories contained in the ICF Generic Set when used as items in the context of Chinese rehabilitation and healthcare. Finally, the steps required to enhance the utility of system-wide implementation of the ICF in rehabilitation and healthcare services are set out.

The Biopharmaceutical Classification System (BCS), which is a scientific approach to categorize active drug ingredient based on its solubility and intestinal permeability into one of the four classes, has been used to set the pharmaceutical quality standards for drug products in western society. However, it has received little attention in the area of Chinese herbal medicine (CHM). This is likely, in part, due to the presence of multiple active components as well as lack of standardization of CHM. In this report, we apply BCS classification to CHMs provisionally as a basis for establishing improved in vitro quality standards. Based on a top-200 drugs selling list in China, a total of 31 CHM products comprising 50 official active marker compounds (AMCs) were provisionally classified according to BCS. Information on AMC content and doses of these CHM products were retrieved from the Chinese Pharmacopoeia. BCS parameters including solubility and permeability of the AMCs were predicted in silico (ACD/Laboratories). A BCS classification of CHMs according to biopharmaceutical properties of their AMCs is demonstrated to be feasible in the current study and can be used to provide a minimum set of quality standards. Our provisional results showed that 44% of the included AMCs were classified as Class III (high solubility, low permeability), followed by Class II (26%), Class I (18%), and Class IV (12%). A similar trend was observed when CHMs were classified in accordance with the BCS class of AMCs. Most (45%) of the included CHMs were classified as Class III, followed by Class II (16%), Class I (10%), and Class IV (6%); whereas 23% of the CHMs were of mixed class due to the presence of multiple individual AMCs with different BCS classifications. Moreover, about 60% of the AMCs were classified as high-solubility compounds (Class I and Class III), suggesting an important role for an in vitro dissolution test in setting quality control standards ensuring consistent biopharmaceutical quality for the commercially available CHM products. That is, provisionally, more than half of the AMCs of the top-selling CHMs included in this study would be candidates for a bioequivalence (BE) biowaiver, based on WHO recommendations and EMEA guidelines. Thus a dissolution requirement on these AMCs would represent a significant advance in the pharmaceutical quality of CHM today.

There is a need for a simple self-administered instrument to assess frailty in community-dwelling seniors. We present a new marker set to assess the functional state of seniors. Contrary to current literature, we focus not only on risks, but also include resources. The questions relate to facts (ways to do things), rather than on subjective information (e.g. exhaustion). It was developed in the context of the Longitudinal Urban Cohort Ageing Study (LUCAS) in Hamburg, Germany. The classification based on these questions proposes operational definitions of the terms fit, pre-frail and frail and is predictive for need for nursing care as well as mortality. A wealth of results establishes the validity of the categorisation compared to other health questions. One of the classification questions concerns cycling. For areas where cycling is not suitable, we propose to replace this question with one about independently walking 500 m. However, the cycling question appears to indicate frailty earlier. The self-administered questionnaire provides a simple, cost-effective way to screen seniors for early signs of declining function in order to start preventive action.

Cross-domain question classification in community question answering via kernel mapping

An increasingly popular method for retrieving information is via the community question answering (CQA) systems such as Yahoo! Answers and Baidu Knows. In CQA, question classification plays an important role to find the answers. However, the labeled training examples for statistical question classifier are fairly expensive to obtain, as they require the experienced human efforts. Meanwhile, unlabeled data are readily available. This paper employs the method of domain adaptation via kernel mapping to solve this problem. In detail, the kernel approach is utilized to map the target-domain data and the source-domain data into a common space, where the question classifiers are trained under the closer conditional probabilities. The kernel mapping function is constructed by domain knowledge. Therefore, domain knowledge could be transferred from the labeled examples in the source domain to the unlabeled ones in the targeted domain. The statistical training model can be improved by using a large number of unlabeled data. Meanwhile, the Hadoop Platform is used to construct the mapping mechanism to reduce the time complexity. Map/Reduce enable kernel mapping for domain adaptation in parallel in the Hadoop Platform. Experimental results show that the accuracy of question classification could be improved by the method of kernel mapping. Furthermore, the parallel method in the Hadoop Platform could effective schedule the computing resources to reduce the running time.

The Chinese restaurant syndrome: an anecdote revisited.

1986-04-01

The Chinese Restaurant Syndrome arose from an anecdote of discomfort experienced after eating Chinese cuisine. Monosodium glutamate has been implicated as the causative agent. Work over the past 17 years has consistently failed to reveal any objective sign accompanying the transient sensations that some individuals experience after the experimental ingestion of monosodium glutamate and it is questionable whether the term 'Chinese Restaurant Syndrome' has any validity. When some common food materials are used in the same experimental setting, similar symptoms can be produced in a limited number of people. Double-blind testing of individuals who identify themselves as suffering the 'syndrome' has failed to confirm the role of monosodium glutamate as the provocative agent.

Chinese nurse stress in Taiwan, Republic of China.

PubMed

Tsai, S L

1993-01-01

An exploratory study was conducted to understand the Chinese nurses' perceptions of their work stress in Taiwan, Republic of China (ROC). Data were based on the written answers to two open-ended questions from the randomly selected Chinese nurses working at 3 of the 10 first-ranked teaching hospitals that had 900-2,000 hospital beds. The findings showed that stressors in work situations for Chinese nurses were similar to those of their Western colleagues in four categories: nursing care related to patient condition, interpersonal relationships, workload, and opportunity for promotion. In addition, the Chinese respondents especially identified pressure in the role of a unit educator as stressful. Any troubled interpersonal relationship of the Chinese nurse may have been experienced as a greater source of pressure than nurses in other cultures. It is suggested that there might be some similar stressors in the nurse work situation when comparing the Chinese nurse working in the modern hospital in Taiwan to the nurses in large hospitals in the Western culture. Yet the difference between these nurses was the greater emphasis the Chinese nurses placed on the value of advanced study and interpersonal harmony.

2016-09-01

The number of older Chinese immigrants living in the United States is increasing steadily. They are faced with challenges to meet their needs for social support and are unlikely to turn to formal services. This case study utilizes an ecological framework to analyze social support among Chinese immigrants age 65 year and older within a Christian Chinese church community, and to explore the ways in which a Chinese church functions as the source of social support for older Chinese immigrants. Seven months of participant observation and ten face-to-face, in-depth interviews were conducted with 65+ Chinese adults who attended one Chinese church in the Southern United State and included questions concerning patterns of support and personal relationships within the church. Findings revealed that gender, living arrangements, working experiences, ability to drive, and English language skills were related to support the older Chinese immigrants sought, received, and provided. Although the Chinese church can be a viable source of supplementary support, some participants in this study felt the support they received from the church was insufficient, particularly in terms of emotional support. Therefore, suggestions are outlined that may assist Chinese churches to be more proactive in better understanding and providing services that meet the different needs and desires of older Chinese immigrants.

2009-02-01

This paper reviews the current status and future directions of borderline personality disorder (BPD) research in China. Although the committee of the third version of the Chinese Classification of Mental Disorders (CCMD-3) rejected BPD as a valid diagnostic category and instead adopted the term impulsive personality disorder (IPD), our literature review on personality disorders from 1979 to 2008 in China indicated that BPD was the most popular research topic among researchers and clinicians. Available empiric evidence on BPD in China provided preliminary support for the construct validity and clinical utility of BPD in clinical and nonclinical Chinese samples. Future studies in the following areas are suggested: 1) developing reliable assessment instruments for measuring BPD pathology in China, 2) comparing the construct validity and phenomenology of CCMD IPD and DSM BPD among Chinese patients, 3) examining potential cultural differences in symptom expression of BPD pathology among the Chinese, and 4) exploring indigenous and imported methods for treating BPD patients in China.

Generally speaking, Japanese acupuncture-moxibustion works of Chinese translation version explained the mechanisms of acupuncture and moxibustion in terms of the theory of western medicine rather than traditional one. It proposed the study on the phenomenon of meridian and collateral, which absorbed the anatomic knowledge of western medicine in the discussion on meridians, collaterals and acupoints; introduced diagnostic methods and techniques of acupuncture and moxibustion and adopted the classification of western medicine system and the diseases in western medicine to discuss the treatment with acupuncture and moxibustion. All of these reflect the academic characteristics of acupuncture and moxibustion in Japan at those times and the position of Chinese scholars, by which the Japanese medical works were introduced for the academic innovation.

In this paper, 104 samples of Chinese rice wines of the same variety (Shaoxing rice wine), collected in three winery ("guyuelongshan", "pagoda" brand, "kuaijishan"), three brewed years (2002, 2004, 2004-2006) were analyzed by near-infrared transmission spectroscopy between 800 and 2500 nm. The spectral differences were studied by principal components analysis (PCA), and Classifications, according the brand, were carried out by discriminant analysis (DA) and partial least squares discriminant analysis (PLSDA). The DA model gained a total accuracy of 94.23% and when used to predict the brand of the validation set samples, a better result, correctly classified all of the three kinds of Chinese rice wine up to 100%, are obtained by PLSDA model. The work reported here is a feasibility study and requires further development with considerable samples of more different brands. Further studies are needed in order to improve the accuracy and robustness, and to extend the discrimination to other Chinese rice wine varieties or brands.

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.

Background Although numerous phenotype based equations for predicting risk of 'hard' coronary heart disease are available, data on the utility of genetic information for such risk prediction is lacking in Chinese populations. Design Case-control study nested within the Singapore Chinese Health Study. Methods A total of 1306 subjects comprising 836 men (267 incident cases and 569 controls) and 470 women (128 incident cases and 342 controls) were included. A Genetic Risk Score comprising 156 single nucleotide polymorphisms that have been robustly associated with coronary heart disease or its risk factors ( p < 5 × 10 -8 ) in at least two independent cohorts of genome-wide association studies was built. For each gender, three base models were used: recalibrated Adult Treatment Panel III (ATPIII) Model (M 1 ); ATP III model fitted using Singapore Chinese Health Study data (M 2 ) and M 3 : M 2 + C-reactive protein + creatinine. Results The Genetic Risk Score was significantly associated with incident 'hard' coronary heart disease ( p for men: 1.70 × 10 -10 -1.73 × 10 -9 ; p for women: 0.001). The inclusion of the Genetic Risk Score in the prediction models improved discrimination in both genders (c-statistics: 0.706-0.722 vs. 0.663-0.695 from base models for men; 0.788-0.790 vs. 0.765-0.773 for women). In addition, the inclusion of the Genetic Risk Score also improved risk classification with a net gain of cases being reclassified to higher risk categories (men: 12.4%-16.5%; women: 10.2% (M 3 )), while not significantly reducing the classification accuracy in controls. Conclusions The Genetic Risk Score is an independent predictor for incident 'hard' coronary heart disease in our ethnic Chinese population. Inclusion of genetic factors into coronary heart disease prediction models could significantly improve risk prediction performance.

Objective To present results of the Kyoto Global Consensus Meeting, which was convened to develop global consensus on (1) classification of chronic gastritis and duodenitis, (2) clinical distinction of dyspepsia caused by Helicobacter pylori from functional dyspepsia, (3) appropriate diagnostic assessment of gastritis and (4) when, whom and how to treat H. pylori gastritis. Design Twenty-three clinical questions addressing the above-mentioned four domains were drafted for which expert panels were asked to formulate relevant statements. A Delphi method using an anonymous electronic system was adopted to develop the consensus, the level of which was predefined as ≥80%. Final modifications of clinical questions and consensus were achieved at the face-to-face meeting in Kyoto. Results All 24 statements for 22 clinical questions after extensive modifications and omission of one clinical question were achieved with a consensus level of >80%. To better organise classification of gastritis and duodenitis based on aetiology, a new classification of gastritis and duodenitis is recommended for the 11th international classification. A new category of H. pylori-associated dyspepsia together with a diagnostic algorithm was proposed. The adoption of grading systems for gastric cancer risk stratification, and modern image-enhancing endoscopy for the diagnosis of gastritis, were recommended. Treatment to eradicate H. pylori infection before preneoplastic changes develop, if feasible, was recommended to minimise the risk of more serious complications of the infection. Conclusions A global consensus for gastritis was developed for the first time, which will be the basis for an international classification system and for further research on the subject.

Research literacy and the practice of evidence-based medicine (EBM) are important initiatives in complementary and alternative medicine (CAM), which requires cultural change within educational institutions for successful implementation. To determine the self-assessed research and EBM perspectives of Chinese medicine Masters degree students at Pacific College of Oriental Medicine, New York campus (PCOM-NY). A survey with 17 close-ended questions and one open-ended question was administered through Survey Monkey to students at PCOM-NY. The survey was sent to 420 Masters students and 176 (41.9%) responded. Students in all four years of the Masters degree indicated a generally high degree of interest in, and support for the value of research. However, increasing years (one to four years) in the program was associated with lower interest in post-graduation research participation and entering the doctoral program, and the fourth year students reported low levels of interest in having greater research content and training in their Masters degree programs. Students who responded to the open-ended question (23% of respondents) expressed enthusiasm for research and concerns about the relevance of research in Chinese medicine. Consistent with findings in similar studies at CAM colleges, interest in research, and EBM of the PCOM-NY Masters students appeared to decline with increasing years in the program. Concerns around paradigm and epistemological issues associated with research and EBM among Chinese medicine students and practitioners warrants further investigation, and may be an important challenge for integrative medicine.

Is Mitochondrial Donation Germ-Line Gene Therapy? Classifications and Ethical Implications.

PubMed

Newson, Ainsley J; Wrigley, Anthony

2017-01-01

The classification of techniques used in mitochondrial donation, including their role as purported germ-line gene therapies, is far from clear. These techniques exhibit characteristics typical of a variety of classifications that have been used in both scientific and bioethics scholarship. This raises two connected questions, which we address in this paper: (i) how should we classify mitochondrial donation techniques?; and (ii) what ethical implications surround such a classification? First, we outline how methods of genetic intervention, such as germ-line gene therapy, are typically defined or classified. We then consider whether techniques of mitochondrial donation fit into these, whether they might do so with some refinement of these categories, or whether they require some other approach to classification. To answer the second question, we discuss the relationship between classification and several key ethical issues arising from mitochondrial donation. We conclude that the properties characteristic of mitochondrial inheritance mean that most mitochondrial donation techniques belong to a new sub-class of genetic modification, which we call 'conditionally inheritable genomic modification' (CIGM). © 2017 John Wiley & Sons Ltd.

Gastric cancer(GC) is a highly heterogeneous malignancy. The present widely used histopathological classifications have gradually failed to meet the needs of individualized diagnosis and treatment. Development of technologies such as microarray and next-generation sequencing (NGS) has allowed GC to be studied at the molecular level. Mechanisms about tumorigenesis and progression of GC can be elucidated in the aspects of gene mutations, chromosomal alterations, transcriptional and epigenetic changes, on the basis of which GC can be divided into several subtypes. The classifications of Tan's, Lei's, TCGA and ACRG are relatively comprehensive. Especially the TCGA and ACRG classifications have large sample size and abundant molecular profiling data, thus, the genomic characteristics of GC can be depicted more accurately. However, significant differences between both classifications still exist so that they cannot be substituted for each other. So far there is no widely accepted molecular classification of GC. Compared with TCGA classification, ACRG system may have more clinical significance in Chinese GC patients since the samples are mostly from Asian population and show better association with prognosis. The molecular classification of GC may provide the theoretical and experimental basis for early diagnosis, therapeutic efficacy prediction and treatment stratification while their clinical application is still limited. Future work should involve the application of molecular classifications in the clinical settings for improving the medical management of GC.

In this paper, we propose an application of non-parametric Bayesian (NPB) models for classification of fetal heart rate (FHR) recordings. More specifically, we propose models that are used to differentiate between FHR recordings that are from fetuses with or without adverse outcomes. In our work, we rely on models based on hierarchical Dirichlet processes (HDP) and the Chinese restaurant process with finite capacity (CRFC). Two mixture models were inferred from real recordings, one that represents healthy and another, non-healthy fetuses. The models were then used to classify new recordings and provide the probability of the fetus being healthy. First, we compared the classification performance of the HDP models with that of support vector machines on real data and concluded that the HDP models achieved better performance. Then we demonstrated the use of mixture models based on CRFC for dynamic classification of the performance of (FHR) recordings in a real-time setting.

Citizen Astronomy in China: An Overview

NASA Astrophysics Data System (ADS)

Ye, Quan-Zhi

2018-01-01

Citizen astronomers have benefited from technological advancements in the recent decades as they fill the scientific gaps left by professional astronomers, in the areas such as time domain observations, visual classification and data mining. Here I present an overview of the current status of citizen astronomy in China. Chinese citizen astronomers have made a visible contribution in the discoveries of new objects; however, comparing to their counterparts in the western world, they appear to be less interested in researches that do not involve making new discovery, such as visual classification, long-term monitoring of objects, and data mining. From a questionnaire survey that aimed to investigate the motivation of Chinese citizen astronomers, we find that this population is predominantly male (92%) who mostly reside in economically developed provinces. A large fraction (69%) of the respondents are students and young professionals younger than the age of 25, which differs significantly from the occupation and age distribution of typical Chinese Internet users as well as the user distribution of large international citizen science projects such as the Galaxy Zoo. This suggests that youth generation in China is more willing to participate citizen astronomy research than average generation. Additionally, we find that interests in astronomy, desire to learn new knowledges, have a fun experience and meet new friends in the community are all important driving factors for Chinese citizen astronomers to participate research. This also differs from their counterparts in western countries. With a large youth population that is interested in astronomy as well as a number of large astronomical facilities that are being planned or built, we believe that citizen astronomy in China has a vast potential. Timely and proper guidance from the professionals will be essential to help citizen astronomers to fulfill this potential.

During smile evaluation and anterior esthetic construction, the anatomic and racial variations should be considered in order to achieve better matching results. The aims of this study were to validate an objective method for recording spontaneous smile process and to categorize the smile and upper lip curvature of Chinese Han-nationality youth. One hundred and eighty-eight Chinese Han-nationality youths (88 males and 100 females) ranged from 20 to 35 years of age were selected. Spontaneous smiles were elicited by watching comical movies and the dynamics of the spontaneous smile were captured continuously with a digital video camera. All subjects' smiles were categorized into three types: commissure, cuspid and gummy smile based on video editing software and final images. Subjects' upper lip curvatures were also measured and divided into three groups: upward, straight and downward. Reliability analysis was conducted to obtain intra-rater reliabilities on twice measurements. The Pearson Chi-square test was used to compare differences for each parameters (α=0.05). In smile classification, 60.6% commissure smile, 33.5% cuspid smile and 5.9% gummy smile were obtained. In upper lip measurement, 26.1% upward, 39.9% straight and 34.0% downward upper lip curvature were determined. The commissure smile group showed statistically significant higher percentage of straight (46.5%) and upward (40.4%) in upper lip curvatures (P<0.05), while cuspid smile group (65.1%) and gummy smile group (72.7%) showed statistically significant higher frequency in downward upper lip curvature (P<0.05). It is evident that differences in upper lip curvature and smile classification exist based on race, when comparing Chinese subjects with those of Caucasian descent, and gender. PMID:23558343

2015-01-01

Objective: To evaluate the technical characteristics and application of mass casualty incident (MCI) primary triage (PT) methods applied in China. Data Sources: Chinese literature was searched by Chinese Academic Journal Network Publishing Database (founded in June 2014). The English literature was searched by PubMed (MEDLINE) (1950 to June 2014). We also searched Official Websites of Chinese Central Government's (http://www.gov.cn/), National Health and Family Planning Commission of China (http://www.nhfpc.gov.cn/), and China Earthquake Information (http://www.csi.ac.cn/). Study Selection: We included studies associated with mass casualty events related to China, the PT applied in China, guidelines and standards, and application and development of the carding PT method in China. Results: From 3976 potentially relevant articles, 22 met the inclusion criteria, 20 Chinese, and 2 English. These articles included 13 case reports, 3 retrospective analyses of MCI, two methods introductions, three national or sectoral criteria, and one simulated field testing and validation. There were a total of 19 kinds of MCI PT methods that have been reported in China from 1950 to 2014. In addition, there were 15 kinds of PT methods reported in the literature from the instance of the application. Conclusions: The national and sectoral current triage criteria are developed mainly for earthquake relief. Classification is not clear. Vague criteria (especially between moderate and severe injuries) operability are not practical. There are no triage methods and research for children and special populations. There is no data and evidence supported triage method. We should revise our existing classification and criteria so it is clearer and easier to be grasped in order to build a real, practical, and efficient PT method. PMID:26415807

Children have formal science instruction from kindergarten in Australia and from Year 3 in China. The purpose of this research was to explore the impact that different approaches to primary science curricula in China and Australia have on children's conceptual understanding of science. Participants were Year 3 children from three schools of high, medium and low socio-economic status in Hunan Province, central south China (n = 135) and three schools of similar socio-economic status in Western Australia (n = 120). The students' understanding was assessed by a science quiz, developed from past Trends in Mathematics and Science Study science released items for primary children. In-depth interviews were carried out to further explore children's conceptual understanding of living things, the Earth and floating and sinking. The results revealed that Year 3 children from schools of similar socio-economic status in the two countries had similar conceptual understandings of life science, earth science and physical science. Further, in both countries, the higher the socio-economic status of the school, the better the students performed on the science quiz and in interviews. Some idiosyncratic strengths and weaknesses were observed, for example, Chinese Year 3 children showed relative strength in classification of living things, and Australian Year 3 children demonstrated better understanding of floating and sinking, but children in both countries were weak in applying and reasoning with complex concepts in the domain of earth science. The results raise questions about the value of providing a science curriculum in early childhood if it does not make any difference to students' conceptual understanding of science.

Categorical perception of intonation contrasts: effects of listeners' language background.

PubMed

Liu, Chang; Rodriguez, Amanda

2012-06-01

Intonation perception of English speech was examined for English- and Chinese-native listeners. F0 contour was manipulated from falling to rising patterns for the final words of three sentences. Listener's task was to identify and discriminate the intonation of each sentence (question versus statement). English and Chinese listeners had significant differences in the identification functions such as the categorical boundary and the slope. In the discrimination functions, Chinese listeners showed greater peakedness than English peers. The cross-linguistic differences in intonation perception were similar to the previous findings in perception of lexical tones, likely due to listeners' language background differences.

Patients in Taiwan with allergic rhinitis seek not only Western medicine treatment but also Traditional Chinese Medicine treatment or integrated Chinese-Western medicine treatment. Various studies have conducted pairwise comparison on Traditional Chinese Medicine, Western medicine, and integrated Chinese-Western medicine treatments. However, none conducted simultaneous analysis of the three treatments. This study analyzed patients with allergic rhinitis receiving the three treatments to identify differences in demographic characteristic and medical use and thereby to determine drug use patterns of different treatments. The National Health Insurance Research Database was the data source, and included patients were those diagnosed with allergic rhinitis (International Classification of Diseases, Ninth Revision, Clinical Modification codes 470-478). Chi-square test and Tukey studentized range (honest significant difference) test were conducted to investigate the differences among the three treatments. Visit frequency for allergic rhinitis treatment was higher in female than male patients, regardless of treatment with Traditional Chinese Medicine, Western medicine, or integrated Chinese-Western medicine. Persons aged 0-19 years ranked the highest in proportion of visits for allergic rhinitis. Traditional Chinese Medicine treatment had more medical items per person-time and daily drug cost per person-time and had the lowest total expenditure per person-time. In contrast, Western medicine had the lowest daily drug cost per person-time and the highest total expenditure per person-time. The total expenditure per person-time, daily drug cost per person-time, and medical items per person-time of integrated Chinese-Western medicine treatment lay between those seen with Traditional Chinese Medicine and Western medicine treatments. Although only 6.82 % of patients with allergic rhinitis chose integrated Chinese-Western medicine treatment, the visit frequency per person-year of integrated Chinese-Western medicine ranked highest. In addition, multiple-composition medicines were used more frequently than single-composition medicines, and mar huang (Ephedra sinica Stapf) was seldom used to decrease the risk of combining medications.

Processing Interrogative Sentence Mood at the Semantic-Syntactic Interface: An Electrophysiological Research in Chinese, German, and Polish

PubMed Central

Kao, Chung-Shan; Dietrich, Rainer; Sommer, Werner

2010-01-01

Background Languages differ in the marking of the sentence mood of a polar interrogative (yes/no question). For instance, the interrogative mood is marked at the beginning of the surface structure in Polish, whereas the marker appears at the end in Chinese. In order to generate the corresponding sentence frame, the syntactic specification of the interrogative mood is early in Polish and late in Chinese. In this respect, German belongs to an interesting intermediate class. The yes/no question is expressed by a shift of the finite verb from its final position in the underlying structure into the utterance initial position, a move affecting, hence, both the sentence's final and the sentence's initial constituents. The present study aimed to investigate whether during generation of the semantic structure of a polar interrogative, i.e., the processing preceding the grammatical formulation, the interrogative mood is encoded according to its position in the syntactic structure at distinctive time points in Chinese, German, and Polish. Methodology/Principal Findings In a two-choice go/nogo experimental design, native speakers of the three languages responded to pictures by pressing buttons and producing utterances in their native language while their brain potentials were recorded. The emergence and latency of lateralized readiness potentials (LRP) in nogo conditions, in which speakers asked a yes/no question, should indicate the time point of processing the interrogative mood. The results revealed that Chinese, German, and Polish native speakers did not differ from each other in the electrophysiological indicator. Conclusions/Significance The findings suggest that the semantic encoding of the interrogative mood is temporally consistent across languages despite its disparate syntactic specification. The consistent encoding may be ascribed to economic processing of interrogative moods at various sentential positions of the syntactic structures in languages or, more generally, to the overarching status of sentence mood in the semantic structure.

Is Mandarin Chinese a Truth-Based Language? Rejecting Responses to Negative Assertions and Questions

PubMed Central

Li, Feifei; González-Fuente, Santiago; Prieto, Pilar; Espinal, M.Teresa

2016-01-01

This paper addresses the central question of whether Mandarin Chinese (MC) is a canonical truth-based language, a language that is expected to express the speaker's disagreement to a negative proposition by means of a negative particle followed by a positive sentence. Eight native speakers of MC participated in an oral Discourse Completion Task that elicited rejecting responses to negative assertions/questions and broad focus statements (control condition). Results show that MC speakers convey reject by relying on a combination of lexico-syntactic strategies (e.g., negative particles such as bù, méi(yǒu), and positive sentences) together with prosodic (e.g., mean pitch) and gestural strategies (mainly, the use of head nods). Importantly, the use of a negative particle, which was the expected outcome in truth-based languages, only appeared in 52% of the rejecting answers. This system puts into question the macroparametric division between truth-based and polarity-based languages and calls for a more general view of the instantiation of a reject speech act that integrates lexical and syntactic strategies with prosodic and gestural strategies.

Societal Projection: Beliefs Concerning the Relationship between Development and Inequality in China

PubMed Central

Xie, Yu; Thornton, Arland; Wang, Guangzhou; Lai, Qing

2012-01-01

We examine how the relationship between development and inequality at the societal level is perceived and evaluated by ordinary Chinese people. We hypothesize that because the Chinese have recently experienced rapid increases in both economic growth and social inequality, they tend to view economic development as a driving force of social inequality. To address this question, we conducted a social survey in 2006 in six Chinese provinces (n = 4,898). The survey data reveal that a large proportion of Chinese people have internalized a causal model in which they project high levels of inequality onto countries they view as more developed and low levels of inequality onto countries they see as less developed. However, results also show that a smaller proportion of Chinese believe in a negative relationship between development and inequality. Hence, the study reveals heterogeneity among ordinary Chinese in their perceptions of the causal relationship between development and inequality. Surprisingly, socioeconomic and demographic characteristics provide no explanatory power in explaining this heterogeneity. PMID:23017918

Adapting cognitive behavioral therapy to meet the needs of Chinese clients: Opportunities and challenges.

2015-06-01

With the growing influence of China (Chinese people/culture) on the world's politics, economy, and culture, the psychological wellbeing of Chinese people is becoming increasingly important for both researchers and practitioners. Despite this, the cultural responsiveness of many conventional psychotherapeutic models has often been brought into question. In contrast, cognitive behavioral therapy (CBT) is rapidly becoming one of the most popular approaches in the mental health service industry and has been successfully adapted into many different cultural contexts. The current article is a theoretical discussion of the opportunities and challenges that CBT faces with respect to how it might meet the cultural needs and preferences of Chinese clients. Suggestions for successful cultural adaptation are offered based on existing research and practices. It is concluded that many features of CBT appear to match well with the Chinese cultural perspective. However, despite this promising start further work is needed to focus specifically on its practical effectiveness for Chinese clients. © 2015 The Authors.

This paper reports an investigation of Chinese-speaking and English-speaking children's general visual perceptual abilities. The Developmental Test of Visual Perception was administered to 41 native Chinese-speaking children of mean age 5 yr. 4 mo. in Hong Kong and 35 English-speaking children of mean age 5 yr. 2 mo. in Melbourne. Of interest were the two interrelated components of visual perceptual abilities, namely, motor-reduced visual perceptual and visual-motor integration perceptual abilities, which require either verbal or motoric responses in completing visual tasks. Chinese-speaking children significantly outperformed the English-speaking children on general visual perceptual abilities. When comparing the results of each of the two different components, the Chinese-speaking students' performance on visual-motor integration was far better than that of their counterparts (ES = 2.70), while the two groups of students performed similarly on motor-reduced visual perceptual abilities. Cultural factors such as written language format may be contributing to the enhanced performance of Chinese-speaking children's visual-motor integration abilities, but there may be validity questions in the Chinese version.

Pedogenic Magnetic Minerals in Soils: Some Tests of Current Models

NASA Astrophysics Data System (ADS)

Egli, R.

2008-12-01

The magnetic enhancement of soils is increasingly used as a proxy for continental climate, since it is related to the formation of pedogenic iron minerals under warm, humid conditions. Ultrafine magnetite is believed to be the major responsible of the magnetic enhancement, however, very little is known on the detailed formation mechanism, ant its relation to the soil iron cycle. Furthermore, the 'textbook' case of the Chinese Loess Plateau is not well replicated around the World: Loessic soils from the Midwestern US are systematically less enhanced than their Chinese counterpart under similar climatic conditions, and many loessic soils in Argentina are not enhanced at all. In trying to find a rationale behind these differences, I will address three main questions that need to be answered in a bottom-up approach to the problem. The first question is whether susceptibility is indeed controlled by fine magnetite, excluding any significant role of other minerals such as ferrihydrite, goethite, and hematite. This is a rock magnetic problem addressing the interpretation of magnetic measurements: is susceptibility an adequate proxy for the concentration of magnetic minerals in soils? Answering this question allows us to think directly in terms of abundance specific magnetic minerals, which is fundamental for any subsequent interpretation. The second question is directed to understanding the role of magnetic minerals in the soil iron cycle and how they are formed. This brings us to a discussion of the transfer function linking magnetic enhancement with climate. Is indeed rainfall the only parameter controlling pedogenesis? Why is rainfall apparently related with the logarithm of susceptibility in enhanced soils? Can we test current pedogenetic models against this empirical transfer function? The third question points to the role of parent material and later dust inputs. Midwestern US and Argentinian loesses are different from Chinese loess. Is this a reason for the differences observed in the magnetic enhancement of the respective soils? Enough material is now available to test current models and hypotheses with respect to the first two questions.

Failure to detect Xenotropic murine leukaemia virus-related virus in Chinese patients with chronic fatigue syndrome

PubMed Central

2010-01-01

Background Recent controversy has surrounded the question of whether xenotropic murine leukaemia virus-related virus (XMRV) contributes to the pathogenesis of chronic fatigue syndrome (CFS). To investigate the question in a Chinese population, 65 CFS patients and 85 blood donor controls were enrolled and multiplex real-time PCR or reverse transcriptase PCR (RT-PCR) was developed to analyze the XMRV infection status of the study participants. The assay was standardized by constructing plasmid DNAs and armored RNAs as XMRV standards and competitive internal controls (CICs), respectively. Results The sensitivities of the multiplex real-time PCR and RT-PCR assays were 20 copies/reaction and 10 IU/ml, respectively, with 100% specificity. The within-run precision coefficient of variation (CV) ranged from 1.76% to 2.80% and 1.70% to 2.59%, while the between-run CV ranged from 1.07% to 2.56% and 1.06% to 2.74%. XMRV was not detected in the 65 CFS patients and 65 normal individuals out of 85 controls. Conclusions This study failed to show XMRV in peripheral blood mononuclear cells (PBMCs) and plasma of Chinese patients with CFS. The absence of XMRV nucleic acids does not support an association between XMRV infection and the development of CFS in Chinese. PMID:20836869

This study aims at utilising Wavelet Packet Transform (WPT) and Support Vector Machine (SVM) algorithm to make objective analysis and quantitative research for the auscultation in Traditional Chinese Medicine (TCM) diagnosis. First, Wavelet Packet Decomposition (WPD) at level 6 was employed to split more elaborate frequency bands of the auscultation signals. Then statistic analysis was made based on the extracted Wavelet Packet Energy (WPE) features from WPD coefficients. Furthermore, the pattern recognition was used to distinguish mixed subjects' statistical feature values of sample groups through SVM. Finally, the experimental results showed that the classification accuracies were at a high level.

In recent years, deep learning has achieved great success in many fields, ranging from voice recognition and image classification to computer vision. In this study we apply DBNs to concerned internet information in Chinese detecting problem, since there are inherent differences between English and Chinese. Contrastive divergence (CD) is employed in the DBNs to learn a multi-layer generative model from numerous unlabeled data. The features obtained by this model are used to initialize the feed-forward neural network, which can be fine-tuned with backpropagation. Experiment results indicate that, the model and training method we proposed can be used to detect the concerned internet information effectively and accurately.

To present results of the Kyoto Global Consensus Meeting, which was convened to develop global consensus on (1) classification of chronic gastritis and duodenitis, (2) clinical distinction of dyspepsia caused by Helicobacter pylori from functional dyspepsia, (3) appropriate diagnostic assessment of gastritis and (4) when, whom and how to treat H. pylori gastritis. Twenty-three clinical questions addressing the above-mentioned four domains were drafted for which expert panels were asked to formulate relevant statements. A Delphi method using an anonymous electronic system was adopted to develop the consensus, the level of which was predefined as ≥80%. Final modifications of clinical questions and consensus were achieved at the face-to-face meeting in Kyoto. All 24 statements for 22 clinical questions after extensive modifications and omission of one clinical question were achieved with a consensus level of >80%. To better organise classification of gastritis and duodenitis based on aetiology, a new classification of gastritis and duodenitis is recommended for the 11th international classification. A new category of H. pylori-associated dyspepsia together with a diagnostic algorithm was proposed. The adoption of grading systems for gastric cancer risk stratification, and modern image-enhancing endoscopy for the diagnosis of gastritis, were recommended. Treatment to eradicate H. pylori infection before preneoplastic changes develop, if feasible, was recommended to minimise the risk of more serious complications of the infection. A global consensus for gastritis was developed for the first time, which will be the basis for an international classification system and for further research on the subject.

To validate the traditional Chinese translated version of the prolapse quality of life questionnaire (P-QOL). The P-QOL questionnaire was translated into traditional Chinese characters and administered to women recruited from gynecologic outpatient clinics of Kaohsiung Chang Gung Memorial Hospital, Kaohsiung, Taiwan. After the test-retest reliability and internal consistency were established in a pilot study, all participants completed the P-QOL questionnaire and were examined in the lithotomy position using the Pelvic Organ Prolapse Quantification System (POP-Q). The construct validity was assessed by comparing symptom scores and quality-of-life domain scores between symptomatic and asymptomatic women. Of the 244 women recruited, 159 were symptomatic for pelvic organ prolapse, and 85 were asymptomatic. The test-retest reliability confirmed a significant positive monotonic correlation between the total scores of each domain (n = 30, Spearman's rho was from 0.411 to 0.888, p < 0.05 of all). All items achieved a Cronbach α > 0.80 showing good internal consistency. Among the 18 symptom questions, the scores differed significantly between symptomatic and asymptomatic women for 12/18 symptom questions. These 12 questions referred to the prolapse/vaginal symptoms. All the quality of life domains differed significantly (p < 0.05) between symptomatic and asymptomatic women except for the domain of sleep/energy (p = 0.108). The traditional Chinese language version of the P-QOL is a reliable instrument for the assessment of symptom severity and impact on quality of life in women with pelvic organ prolapse.

Limited research has investigated how culture impacts expressions of social support, which is crucial in developing culturally sensitive care. Using a classification based on theories of social support, we examined the social support experiences of 49 Chinese immigrant mental health consumers with psychosis, paying particular attention to frequency and sources. We found that the most common forms of social support were belonging and companionship, perceived emotional support, social control, and perceived instrumental support, while self-esteem and sense of mastery were the least common forms. Family and friends were the main sources of support. These results demonstrate the influence of Confucian values of renqing (or fulfillment of relational obligations) and guanxi (or social networks) and the negative effects of stigma in diminishing the social standing of these consumers by compromising 'personhood.' Clinical implications for increasing the cultural competency of clinicians and improving the mental health outcomes of Chinese immigrants are discussed.

Updating topographic geospatial databases is often performed based on current remotely sensed images. To automatically extract the object information (labels) from the images, supervised classifiers are being employed. Decisions to be taken in this process concern the definition of the classes which should be recognised, the features to describe each class and the training data necessary in the learning part of classification. With a view to large scale topographic databases for fast developing urban areas in the Kingdom of Saudi Arabia we conducted a case study, which investigated the following two questions: (a) which set of features is best suitable for the classification?; (b) what is the added value of height information, e.g. derived from stereo imagery? Using stereoscopic GeoEye and Ikonos satellite data we investigate these two questions based on our research on label tolerant classification using logistic regression and partly incorrect training data. We show that in between five and ten features can be recommended to obtain a stable solution, that height information consistently yields an improved overall classification accuracy of about 5%, and that label noise can be successfully modelled and thus only marginally influences the classification results.

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.

Chinese cherry [Cerasus pseudocerasus (Lindl.) G.Don] is a commercially important fruit crop in China, but its structure patterns and domestication history remain imprecise. To address these questions, we estimated the genetic structure and domestication history of Chinese cherry using 19 nuclear microsatellite markers and 650 representative accessions (including 118 Cerasus relatives) selected throughout their natural eco-geographical distributions. Our structure analyses detected no genetic contribution from Cerasus relatives to the evolution history of Chinese cherry. A separate genetic structure was detected in wild Chinese cherries and rough geographical structures were observed in cultivated Chinese cherries. One wild (wild Chinese cherry, WC) and two cultivated (cultivated Chinese cherry, CC1 and CC2) genetic clusters were defined. Our approximate Bayesian computation analyses supported an independent domestication history with two domestication events for CC1 and CC2, happening about 3900 and 2200 years ago, respectively. Moderate loss of genetic diversity, over 1000-year domestication bottlenecks and divergent domestication in fruit traits were also detected in cultivated Chinese cherries, which is highly correlated to long-term clonal propagation and different domestication trends and preferences. Our study is the first to comprehensively and systematically investigate the structure patterns and domestication history for Chinese cherry, providing important references for revealing the evolution and domestication history of perennial woody fruit trees.

Liu, Ning; Neuhaus, Birgit Jana

2017-08-01

Given the globalization of science education and the different cultures between China and Germany, we tried to compare and explain the differences on teacher questions and real life instances in biology lessons between the two countries from a culture-related perspective. 22 biology teachers from China and 21 biology teachers from Germany participated in this study. Each teacher was videotaped for one lesson on the unit blood and circulatory system. Before the teaching unit, students' prior knowledge was tested with a pretest. After the teaching unit, students' content knowledge was tested with a posttest. The aim of the knowledge tests here was for the better selection of the four samples for qualitative comparison in the two countries. The quantitative analysis showed that more lower-order teacher questions and more real life instances that were introduced after learning relevant concepts were in Chinese lessons than in German lessons. There were no significant differences in the frequency of higher-order questions or real life instances that were introduced before learning concepts. Qualitative analysis showed that both German teachers guided students to analyze the reasoning process of Landsteiner experiment, but nor Chinese teachers did that. The findings reflected the subtle influence of culture on classroom teaching. Relatively, Chinese biology teachers focused more on learning content and the application of the content in real life; German biology teachers emphasized more on invoking students' reasoning and divergent thinking.

The objectives were to investigate intramuscular fat (IMF) content,Warner–Bratzler shear force(WBSF) and sensory attributes of Chinese fattened yellow crossbred steer beef with different quality grades, and to determine the relationship between WBSF and Chinese consumers' sensory tender. WBSF of grades A1 to A5 decreased from 50.6 N to 33.1 N with IMF % increased from4.26 to 24.55 (P b 0.05). Consumer panelists showed more likeability grades A4 and A5 with no difference between them. Grades A2 and A3 were slightly preferred (P b 0.05). Grade A1 was undesirable. A regression relationship between WBSF and sensory tender was found, which indicated that consumers disliked beef when WBSF N55.43 N and preferred those with WBSF b41.4 N. The range of 41.4 N to 55.43 N was intermediate. Hence, WBSF N55.43 & b41.4 N allow classification of tough and tender for beef tenderness for Chinese consumers, and grade A4 was recommended as suitable top grade.

Principal Component 2-D Long Short-Term Memory for Font Recognition on Single Chinese Characters.

2016-03-01

Chinese character font recognition (CCFR) has received increasing attention as the intelligent applications based on optical character recognition becomes popular. However, traditional CCFR systems do not handle noisy data effectively. By analyzing in detail the basic strokes of Chinese characters, we propose that font recognition on a single Chinese character is a sequence classification problem, which can be effectively solved by recurrent neural networks. For robust CCFR, we integrate a principal component convolution layer with the 2-D long short-term memory (2DLSTM) and develop principal component 2DLSTM (PC-2DLSTM) algorithm. PC-2DLSTM considers two aspects: 1) the principal component layer convolution operation helps remove the noise and get a rational and complete font information and 2) simultaneously, 2DLSTM deals with the long-range contextual processing along scan directions that can contribute to capture the contrast between character trajectory and background. Experiments using the frequently used CCFR dataset suggest the effectiveness of PC-2DLSTM compared with other state-of-the-art font recognition methods.

To estimate the prevalence of self-reported symptoms associated with temporomandibular disorders (TMD) and treatment-seeking in adult Chinese in Hong Kong. A telephone survey technique was used to identify 1,526 randomly selected Cantonese-speaking individuals aged 18 years or over. Standard questions were asked about joint and jaw muscle pain, jaw opening, and joint sounds. In addition, questions on tooth grinding and clenching, sleep patterns, and treatment-seeking behavior were posed. Jaw pain was reported by 33% of the population. Only 5% of them had frequent pain, with two thirds of this subgroup having moderate to severe symptoms. The prevalence of frequent problems with jaw opening and joint clicking was 0.3% and 1.8%, respectively. There were no gender-related differences in the reporting of TMD symptoms or related conditions. One percent of the Hong Kong Chinese population had TMD-related jaw pain that was of moderate or severe intensity and occurred frequently; 0.6% of the population had sought treatment for jaw pain, impaired jaw opening, or joint clicking that occurred often in the previous year.

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.

This paper aims to explore a comprehensive assessment method combined traditional Chinese medicinal material specifications with quantitative quality indicators. Seventy-six samples of Notopterygii Rhizoma et Radix were collected on market and at producing areas. Traditional commercial specifications were described and assigned, and 10 chemical components and volatile oils were determined for each sample. Cluster analysis, Fisher discriminant analysis and correspondence analysis were used to establish the relationship between the traditional qualitative commercial specifications and quantitative chemical indices for comprehensive evaluating quality of medicinal materials, and quantitative classification of commercial grade and quality grade. A herb quality index (HQI) including traditional commercial specifications and chemical components for quantitative grade classification were established, and corresponding discriminant function were figured out for precise determination of quality grade and sub-grade of Notopterygii Rhizoma et Radix. The result showed that notopterol, isoimperatorin and volatile oil were the major components for determination of chemical quality, and their dividing values were specified for every grade and sub-grade of the commercial materials of Notopterygii Rhizoma et Radix. According to the result, essential relationship between traditional medicinal indicators, qualitative commercial specifications, and quantitative chemical composition indicators can be examined by K-mean cluster, Fisher discriminant analysis and correspondence analysis, which provide a new method for comprehensive quantitative evaluation of traditional Chinese medicine quality integrated traditional commodity specifications and quantitative modern chemical index.

Contrast agents help to improve visibility in magnetic resonance (MR) imaging. However, owing to the large interstitial spaces of the liver, there is a reduction in the natural contrast gradient between lesions and healthy tissue. This study was undertaken to evaluate the efficacy and safety of the liver-specific MR imaging contrast agent gadoxetate disodium (Gd-EOB-DTPA) in Chinese patients. This was a single-arm, open-label, multicenter study in patients with known or suspected focal liver lesions referred for contrast-enhanced MR imaging. MR imaging was performed in 234 patients before and after a single intravenous bolus of Gd-EOB-DTPA (0.025 mmol/kg body weight). Images were evaluated by clinical study investigators and three independent, blinded radiologists. The primary efficacy endpoint was sensitivity in lesion detection. Gd-EOB-DTPA improved sensitivity in lesion detection by 9.46% compared with pre-contrast imaging for the average of the three blinded readers (94.78% vs 85.32% for Gd-EOB-DTPA vs pre-contrast, respectively). Improvements in detection were more pronounced in lesions less than 1 cm. Gd-EOB-DTPA improved diagnostic accuracy in lesion classification. This open-label study demonstrated that Gd-EOB-DTPA improves diagnostic sensitivity in liver lesions, particularly in those smaller than 1 cm. Gd-EOB-DTPA also significantly improves the diagnostic accuracy in lesion classification, and furthermore, Gd-EOB-DTPA is safe in Chinese patients with liver lesions.

Chinese herbal medicine (CHM) has been commonly used in treating liver diseases in Asian countries. To conduct a large-scale pharmacoepidemiological study and evaluate the frequency and pattern of CHM prescriptions in treating chronic hepatitis. We obtained the database of traditional Chinese medicine outpatient claims from the national health insurance in Taiwan for the whole 2002. Patients with chronic hepatitis were identified by the corresponding diagnosis of International Classification of Disease among claimed visiting files. Corresponding prescription files were analyzed, and association rule were applied to evaluate the co-prescription of CHM in treating chronic hepatitis. Among the 91,080 subjects treated by CHM for chronic hepatitis, the peak age was in the 40 s, followed by 30 s and 50 s. Male/female ratio was 2.07:1. Long-dan-xie-gan-tang and Saliva miltiorrhiza (Dan-shen) were the most commonly prescribed Chinese herbal formula and single herbal drug, respectively. The most common two-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza, and the most common three-drug prescription was Jia-wei-xia-yao-san plus Saliva miltiorrhiza and Artemisia capillaries (Yin-chen-hao). This study showed the utilization pattern of Chinese herbal drugs or formulae in treating chronic hepatitis. Further researches and clinical trials are needed to evaluate the efficacy of these Chinese herbs or its ingredients in treating chronic hepatitis.

The purpose of this study is to determine the most commonly tested topics and the question taxonomy of the American Academy of Orthopaedic Surgeons Self-Assessment Examinations (SAE) from 2009 through 2014. All SAEs were analyzed from 2009 through 2014. The SAEs were separated by subject and the questions of each SAE were analyzed for topic, taxonomic classification, and question type. A total of 2107 questions were reviewed from 10 different subjects. In all, 6 of the 9 subjects had roughly 1/3 of their questions composed of the 3 most commonly tested topics. Each subject had at least 1 trauma-related question within its top 5 most commonly tested topics. Almost half (47%) of all questions were of taxonomy 1 classification and 29% were taxonomy 3. The Basic Science SAEs had the greatest percentage of taxonomy 1 questions of any subject (83%) whereas Trauma contained the highest percentage of taxonomy 3 questions (47%). Certain topics within each subject are consistently tested more often than other topics. In general, the 3 most commonly tested topics comprise about one-third of total questions and orthopedic surgeons should be very familiar with these topics in order to best prepare for standardized examinations.

To accelerate our endeavors to overcome cancer, Chinese Journal of Cancer has launched a program of publishing 150 most important questions in cancer research and clinical oncology. In this article, 10 more questions are presented as follows. Question 15: Can tumor-induced erythrogenesis provide qualified red blood cells for carrying oxygen to distant organs? Question 16: Can we overcome tumor resistance to platinum-containing antineoplastic drugs by activating the sensitivity factors in the tumor? Question 17: How can a cancer cell stay dormant for years? Question 18: Why do cancer cells use distinct transcriptomic and proteomic programs to reach the same metastatic phenotype? Question 19: Why do some cancers regress spontaneously? Question 20: What are the regulatory mechanisms occurring in donor cells that determine selective sorting of biological content into vesicles and their biological consequences in recipient cells? Are the genetic transfer and exchange of biological messages between cells transient? Is the phenotypic manipulation of recipient cells temporary or prolonged and persistent? If extracellular vesicles possess immune-modulatory potential, how could they be exploited for immune interventions and cancer immunotherapy? Presumably the cargo of extracellular vesicles reflects the cells of their origin and can be used for cancer diagnosis, how could the uniform/stringent capture criteria be met universally for applying EVs in point-of-care diagnostics for cancer patients? Question 21: Can we use self-sampling technologies to monitor the tumor genetic alterations for more precise targeted therapy? Can we cure a heterogeneous tumor by sequentially targeting the driver molecules? Question 22: Can we postpone the onset of non-infection-related cancers? Question 23: How many types of cells can jointly form the tumor vasculature to provide blood supply for tumor progression? Question 24: How tumor cells transmit their epigenetic features to daughter cells and maintain the malignant phenotype?

To develop a new adverse event (AE) classification for the interventional radiology (IR) procedures and evaluate its clinical, research, and educational value compared with the existing Society of Interventional Radiology (SIR) classification via an SIR member survey. A new AE classification was developed by members of the Standards of Practice Committee of the SIR. Subsequently, a survey was created by a group of 18 members from the SIR Standards of Practice Committee and Service Lines. Twelve clinical AE case scenarios were generated that encompassed a broad spectrum of IR procedures and potential AEs. Survey questions were designed to evaluate the following domains: educational and research values, accountability for intraprocedural challenges, consistency of AE reporting, unambiguity, and potential for incorporation into existing quality-assurance framework. For each AE scenario, the survey participants were instructed to answer questions about the proposed and existing SIR classifications. SIR members were invited via online survey links, and 68 members participated among 140 surveyed. Answers on new and existing classifications were evaluated and compared statistically. Overall comparison between the two surveys was performed by generalized linear modeling. The proposed AE classification received superior evaluations in terms of consistency of reporting (P < .05) and potential for incorporation into existing quality-assurance framework (P < .05). Respondents gave a higher overall rating to the educational and research value of the new compared with the existing classification (P < .05). This study proposed an AE classification system that outperformed the existing SIR classification in the studied domains. Copyright © 2017 SIR. Published by Elsevier Inc. All rights reserved.

Objective To report our experience with Chinese minimally invasive percutaneous nephrolithotomy (Chinese MPCNL) to manage patients with intrarenal stones in solitary kidney, and evaluate the safety, efficiency and feasibility of this technique. Methods Forty-one patients with intrarenal stones in solitary kidney underwent Chinese MPCNL in our department from March 2009 to February 2011. Demographic characteristics, operative parameters, number of tracts, stone-free rates (SFRs), stone analyses, hemoglobin levels, nephrostomy tube removal time, hospitalization time, and complications were evaluated. Serum creatinine (Scr) and glomerular filtration rate (GFR) were measured preoperatively, postoperatively at 1 month, and each follow-up visit. The 5-stage classification of chronic kidney disease (CKD) was used according to the National Kidney Foundation guidelines. Results The initial stone-free status was achieved in 35 (85.4%) patients after Chinese MPCNL. The mean follow-up time was 16.9±4.7 months (range: 12–24), and the final SFR improved to 97.6% after auxiliary procedures. Among all patients, complex stones were detected in 26 (63.4%) patients, and 9 (22.0%) required multiple tracts. The mean operative time and mean hospitalization time were 71.3±23.5 min (range: 40–139) and 6.1±0.5 days (range: 5–11), respectively. During preoperative period and postoperative period (1 month), Scr were 132.1±41.3 umol/L (range: 78.2–231.4) and 108.9±30.7 umol/L (range: 71.6–136.9), respectively (P<0.05), while GFR were 74.9±24.2 ml/min (range: 35–110) and 83.9±27.4 ml/min (range: 65–110), respectively (P<0.05). According to CKD classification, the renal function was stable, improved, and worse in 29 (70.7%), 11 (26.8%), and 1 (2.5%) patients, compared with the preoperative levels. No patient progressed to end-stage renal disease requiring dialysis. Conclusions Our experience with Chinese MPCNL demonstrates that it is safe, feasible and efficient for managing the intrarenal calculi in solitary kidney with a low complication rate. At long-term follow-up, renal function stabilized or even improved in the majority of patients with solitary kidney. PMID:22808197

The aim of this study was to improve our understanding of depression and anxiety among older immigrant Chinese Australians. The study was based on the National Ageing Research Institute's Cultural Exchange Model, an iterative process of exchange between researchers and stakeholders. The project involved a range of components including consultations with health professionals and community workers about perceptions of depression and anxiety within the Chinese community. This paper reports on these consultation findings. Thematic analysis generated five main categories to explain participants' perceptions of depression and anxiety within the Chinese community. Themes included: lack of knowledge; personal weakness rather than illness; stigma; somatisation; and experience of migration in later life. Responses to questions about education and information dissemination were collated separately and reported. Views of depression and anxiety among older Chinese people suggest that educating the community may be an important way to improve mental health literacy and help-seeking behaviour. © 2016 AJA Inc.

For the last several decades, Chinese society has experienced transformative changes. How are these changes understood among Chinese people? To examine this question, Part 1 in this research solicited folk beliefs of cultural change from a group of Chinese participants in an open-ended format, and the generated folk beliefs were rated by another group of participants in Part 2 to gage each belief's level of agreement. Part 3 plotted the folk beliefs retained in Part 2 using the Google Ngram Viewer in order to infer the amount of intellectual interests that each belief has received cross-temporarily. These analyses suggested a few themes in Chinese folk beliefs of cultural change (1) rising perceived importance of materialism and individualism in understanding contemporary Chinese culture and Chinese psychology relative to those of the past (2) rising perceived importance of freedom, democracy and human rights and (3) enduring perceived importance of family relations and friendship as well as patriotism. Interestingly, findings from Parts 2 and 3 diverged somewhat, illuminating possible divergence between folk beliefs and intellectual interests especially for issues related to heritage of Confucianism.

To compare diabetes prevalence among Asian Americans by World Health Organization and U.S. BMI classifications. Data on Asian American adults (n = 7,414) from the National Health Interview Survey for 1997-2005 were analyzed. Diabetes prevalence was estimated across weight and ethnic group strata. Regardless of BMI classification, Asian Indians and Filipinos had the highest prevalence of overweight (34-47 and 35-47%, respectively, compared with 20-38% in Chinese; P < 0.05). Asian Indians also had the highest ethnic-specific diabetes prevalence (ranging from 6-7% among the normal weight to 19-33% among the obese) compared with non-Hispanic whites: odds ratio (95% CI) for Asian Indians 2.0 (1.5-2.6), adjusted for age and sex, and 3.1 (2.4-4.0) with additional adjustment for BMI. Asian Indian ethnicity, but not other Asian ethnicities, was strongly associated with diabetes. Weight classification as a marker of diabetes risk may need to accommodate differences across Asian subgroups.

Symbolic numerical magnitude processing skills are assumed to be fundamental to arithmetic learning. It is, however, still an open question whether better arithmetic skills are reflected in symbolic numerical magnitude processing skills. To address this issue, Chinese and German third graders were compared regarding their performance in arithmetic tasks and in a symbolic numerical magnitude comparison task. Chinese children performed better in the arithmetic tasks and were faster in deciding which one of two Arabic numbers was numerically larger. The group difference in symbolic numerical magnitude processing was fully mediated by the performance in arithmetic tasks. We assume that a higher degree of familiarity with arithmetic in Chinese compared to German children leads to a higher speed of retrieving symbolic numerical magnitude knowledge. PMID:27630606

Using the Rose Angina Questionnaire cross-culturally: the importance of consulting lay people when translating epidemiological questionnaires.

The Rose Angina Questionnaire (RAQ) is an important measure of coronary heart disease prevalence. It has been shown to perform inconsistently across some ethnic groups in Britain. This study investigates whether the best available versions of the RAQ in Punjabi and Cantonese were linguistically equivalent to the English version. Interviews were carried out with lay people from the Pakistani, Chinese and European-origin communities in Scotland to assess the versions of the RAQ used in the Newcastle Heart Project (the best available versions). For each questionnaire item, participants were asked to elaborate on their understanding of the question and the meaning of keywords or phrases. Problems were discovered with the Punjabi and Cantonese translations of the RAQ. For example, the translation for 'chest' was interpreted by some Pakistani and Chinese women to mean 'breasts'. 'Walking uphill' was translated in Chinese as 'walking the hill', without stipulation of the direction, so that some Cantonese speakers interpreted the question as pertaining to walking downhill. Many Chinese interpreted RAQ items to be referring to breathlessness rather than chest pain due to ambiguous wording. Existing versions of the RAQ are unlikely to be yielding data that are cross-culturally valid or comparable. For robust health survey research in languages other than that in which the questionnaire was developed, lay assessment of questionnaires prior to and after translation is a necessity rather than a luxury.

Chinese cabbage ( Brassica rapa L. ssp . pekinensis ) is a widely cultivated and economically important vegetable crop with typical leaf curvature. The TCP (Teosinte branched1, Cycloidea, Proliferating cell factor) family proteins are plant-specific transcription factors (TFs) and play important roles in many plant biological processes, especially in the regulation of leaf curvature. In this study, 39 genes encoding TCP TFs are detected on the whole genome of B. rapa. Based on the phylogenetic analysis of TCPs between Arabidopsis thaliana and Brassica rapa , TCP genes of Chinese cabbage are named from BrTCP1a to BrTCP24b . Moreover, the chromosomal location; phylogenetic relationships among B. rapa , A. thaliana , and rice; gene structures and protein conserved sequence alignment; and conserved domains are analyzed. The expression profiles of BrTCPs are analyzed in different tissues. To understand the role of Chinese cabbage TCP members in regulating the curvature of leaves, the expression patterns of all BrTCP genes are detected at three development stages essential for leafy head formation. Our results provide information on the classification and details of BrTCPs and allow us to better understand the function of TCPs involved in leaf curvature of Chinese cabbage.

Ensemble learning has been proved to improve the generalization ability effectively in both theory and practice. In this paper, we briefly outline the current status of research on it first. Then, a new deep neural network-based ensemble method that integrates filtering views, local views, distorted views, explicit training, implicit training, subview prediction, and Simple Average is proposed for biomedical time series classification. Finally, we validate its effectiveness on the Chinese Cardiovascular Disease Database containing a large number of electrocardiogram recordings. The experimental results show that the proposed method has certain advantages compared to some well-known ensemble methods, such as Bagging and AdaBoost. PMID:27725828

Background. Social engagement is a key indicator of older adults’ later life quality and health status, but few studies have comprehensively examined social engagement patterns of U.S. Chinese older adults. This study assesses social engagement patterns among U.S. Chinese older adults. Methods. Data were collected by the Population Study of Chinese Elderly project, a cross-sectional population-based study of 3,159U.S. Chinese older adults aged 60 and older in the greater Chicago area. Social engagement patterns were examined with a list of 16 social engagement activity related questions. Analysis of variance and Pearson or Spearman correlation coefficients were used to examine correlations between sociodemographic and health characteristics and social engagement. Results. Age was negatively associated with social engagement actives for Chinese older adults. Although education had a significant positive correlation on older adults’ participation in social engagement activities, income did not show any significant correlation. Perceived health status and quality of life were also positively correlated with social engagement. Chinese older adults were more likely to visit community centers than any other social or cultural venues. Conclusions. This study highlights the important role community centers play in the lives of Chinese older adults. Further, longitudinal studies are also necessary to understand the predictors and outcomes of social engagement levels among Chinese older adults. PMID:25378453

Cannabis in Chinese Medicine: Are Some Traditional Indications Referenced in Ancient Literature Related to Cannabinoids?

Brand, E. Joseph; Zhao, Zhongzhen

2017-01-01

Cannabis sativa L. (Cannabaceae) has a long history of utilization as a fiber and seed crop in China, and its achenes (“seeds”) as well as other plant parts have been recorded in Chinese medical texts for nearly 2000 years. While the primary applications of cannabis in Chinese medicine center around the use of the achenes, ancient indications for the female inflorescence, and other plant parts include conditions such as pain and mental illness that are the subject of current research into cannabinoids such as cannabidiol (CBD) and Δ9-tetrahydrocannabinol (THC). However, little previous research has been conducted to analyze the Chinese medical literature in light of recent advances in the pharmacology and taxonomy of cannabis, and most of the relevant Chinese historical records have not yet been translated into Western languages to facilitate textual research. Furthermore, many key questions remain unresolved in the Chinese literature, including how various traditional drug names precisely correspond to different plant parts, as well as the implications of long-term selection for fiber-rich cultivars on the medical applications of cannabis in Chinese medicine. In this article, prominent historical applications of cannabis in Chinese medicine are chronologically reviewed, and indications found in ancient Chinese literature that may relate to cannabinoids such as CBD and Δ9-THC are investigated.

This study validated the Patellofemoral Pain Severity Scale translated into Chinese. The Chinese Patellofemoral Pain Severity Scale was translated from the original English version following standard forward and backward translation procedures recommended by the International Society for Pharmacoeconomics and Outcomes Research. The survey was then conducted in clinical settings by a questionnaire comprising the Chinese Patellofemoral Pain Severity Scale, Kujala Scale and Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index. Eighty-four Chinese reading patients with patellofemoral pain were recruited from physical therapy clinics. Internal consistency of the translated instrument was measured by Cronbach alpha. Convergent validity was examined by Spearman rank correlation coefficient (rho) tests by comparing its score with the validated Chinese version of the Kujala Scale and the WOMAC Osteoarthritis Index while the test-retest reliability was evaluated by administering the questionnaires twice. Cronbach alpha values of individual questions and their overall value were above 0.85. Strong association was found between the Chinese Patellofemoral Pain Severity Scale and the Kujala Scale (rho = -0.72, p < 0.001). Moderate correlation was also found between Chinese Patellofemoral Pain Severity Scale with the WOMAC Osteoarthritis Index (rho = 0.63, p < 0.001). Excellent test-retest reliability (Intraclass correlation coefficient = 0.98) was demonstrated. The Chinese translated version of the Patellofemoral Pain Severity Scale is a reliable and valid instrument for patients with patellofemoral pain.

Overweight and obesity in Asian children are increasing at an alarming rate; therefore a better understanding of the relationship between BMI and percentage body fat (%BF) in this population is important. A total of 1039 children aged 8-10 years, encompassing a wide BMI range, were recruited from China, Lebanon, Malaysia, The Philippines and Thailand. Body composition was determined using the 2H dilution technique to quantify total body water and subsequently fat mass, fat-free mass and %BF. Ethnic differences in the BMI-%BF relationship were found; for example, %BF in Filipino boys was approximately 2 % lower than in their Thai and Malay counterparts. In contrast, Thai girls had approximately 2.0 % higher %BF values than in their Chinese, Lebanese, Filipino and Malay counterparts at a given BMI. However, the ethnic difference in the BMI-%BF relationship varied by BMI. Compared with Caucasian children of the same age, Asian children had 3-6 units lower BMI at a given %BF. Approximately one-third of the obese Asian children (%BF above 25 % for boys and above 30 % for girls) in the study were not identified using the WHO classification and more than half using the International Obesity Task Force classification. Use of the Chinese classification increased the sensitivity. Results confirmed the necessity to consider ethnic differences in body composition when developing BMI cut-points and other obesity criteria in Asian children.

There is a growing move to consult public databases following receipt of a genetic test result from a clinical laboratory; however, the well-documented limitations of these databases call into question how often clinicians will encounter discordant variant classifications that may introduce uncertainty into patient management. Here, we evaluate discordance in BRCA1 and BRCA2 variant classifications between a single commercial testing laboratory and a public database commonly consulted in clinical practice. BRCA1 and BRCA2 variant classifications were obtained from ClinVar and compared with the classifications from a reference laboratory. Full concordance and discordance were determined for variants whose ClinVar entries were of the same pathogenicity (pathogenic, benign, or uncertain). Variants with conflicting ClinVar classifications were considered partially concordant if ≥1 of the listed classifications agreed with the reference laboratory classification. Four thousand two hundred and fifty unique BRCA1 and BRCA2 variants were available for analysis. Overall, 73.2% of classifications were fully concordant and 12.3% were partially concordant. The remaining 14.5% of variants had discordant classifications, most of which had a definitive classification (pathogenic or benign) from the reference laboratory compared with an uncertain classification in ClinVar (14.0%). Here, we show that discrepant classifications between a public database and single reference laboratory potentially account for 26.7% of variants in BRCA1 and BRCA2 . The time and expertise required of clinicians to research these discordant classifications call into question the practicality of checking all test results against a database and suggest that discordant classifications should be interpreted with these limitations in mind. With the increasing use of clinical genetic testing for hereditary cancer risk, accurate variant classification is vital to ensuring appropriate medical management. There is a growing move to consult public databases following receipt of a genetic test result from a clinical laboratory; however, we show that up to 26.7% of variants in BRCA1 and BRCA2 have discordant classifications between ClinVar and a reference laboratory. The findings presented in this paper serve as a note of caution regarding the utility of database consultation. © AlphaMed Press 2017.

We present data questioning the adequacy of standard back-translation procedures for investigating emotion states across cultures (Brislin, 1970). Our data indicate that the Chinese back-translation of the term disgust has led cross-cultural researchers to accept terms whose themes, goals, and motivations are more akin to the English term anger. Evidence is presented showing that, compared with the standard back-translation method, a more painstaking interview method found a better translational Chinese equivalent for the English term disgust. Implications for the use of back-translation in cross-cultural research are considered. (PsycINFO Database Record (c) 2010 APA, all rights reserved).

Does red undermine individuals' intellectual performance? A test in China.

Previous research shows that red impairs individuals' performance on challenging intellectual tasks in achievement situations. However, no research to date has examined this issue in Chinese society. In China, red has a positive connotation in general (unlike in the West), but also has a negative connotation for students, given that teachers mark incorrect answers in red (like in the West). Therefore, the question of whether red promotes or undermines intellectual performance for Chinese individuals needs to be tested. The present research investigated this and found, consistent with findings obtained in the West, that red undermined the intellectual performance of Chinese students. Future directions and potential mechanisms are discussed. © 2014 International Union of Psychological Science.

This study investigated the influence of the symbol type and numerical distance of numbers on the amplitudes and peak latencies of event-related potentials (ERPs). Our aim was to (1) determine the point in time of magnitude information access in visual number processing; and (2) identify at what stage the advantage of Arabic digits over Chinese verbal numbers occur. ERPs were recorded from 64 scalp sites while subjects (n=26) performed a classification task. Results showed that larger ERP amplitudes were elicited by numbers with distance-close condition in comparison to distance-far condition in the VPP component over centro-frontal sites. Furthermore, the VPP latency varied as a function of the symbol type, but the N170 did not. Such results demonstrate that magnitude information access takes place as early as 150 ms after onset of visual number stimuli and the advantage of Arabic digits over verbal numbers should be localized to the VPP component. We establish the VPP component as a critical ERP component to report in studies of numerical cognition and our results call into question the N170/VPP association hypothesis and the serial-stage model of visual number comparison processing.

We investigated the current level of knowledge of Chinese heart failure (HF) guidelines among physicians, as a reference for the promotion and transformation of HF knowledge. Physicians from 88 hospitals in 27 provinces of China completed our survey between July and December 2014. The questions covered the main points included in the Chinese HF diagnosis and treatment guidelines (2014). A total of 2146 physicians, aged 20 to 62 years (35.6 ± 7.6 years), completed the survey. The correctness rate of their answers to the 15 multiple-choice questions in the HF questionnaire was generally low (mean 32.6%). The mean correctness rate for 10 blank-filling questions about the target doses of angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists, and β-blockers was 42.5%. On the basis of their responses, physicians whose knowledge of the guidelines was "excellent," "good," "medium," and "bad" accounted for 1.1%, 11.4%, 14.2%, and 73.4%, respectively. Physicians who possessed a higher level of qualifications had significantly greater awareness of HF guidelines than those with relatively low qualifications (P < .001). A statistically significant association was found between hospital level and adherence to treatment guidelines (P < .001). A significant difference was also observed among physicians in different practice scopes (P < .001). The survey found an obvious deficiency in physicians' mastery of fundamental knowledge about HF. There is a need to improve physicians' education about HF in China.

The Anotylus sculpturatus species group is one of the relatively well-defined assemblages within the very large genus Anotylus Thomson, 1859 of the subfamily Oxytelinae (Coleoptera: Staphylinidae). This paper briefly examines the species group classification of the genus Anotylus and concentrates mainly on the taxonomy of Anotylus sculpturatus group. The paper reviews the Chinese fauna of 13 species, with seven new species described here: Anotylus benisculptilis sp. nov., A. nigelisculptilis sp. nov. and A. brevisculptilis sp. nov. from Sichuan, A. varisculptilis sp. nov. from Yunnan and Sichuan, A. nitelisculptilis sp. nov. from Sichuan, Ningxia, Gansu and Shaanxi, A. rectisculptilis sp. nov. from Zhejiang, and A. extrasculptilis sp. nov. from Yunnan. Lectotypes are designated for Anotylus chinkiangensis (Bernhauer, 1938) and A. subsericeus (Bernhauer, 1938). Color figures and line-drawings are provided for all the new species and most of the earlier known species from China. A preliminary key to the species groups of Anotylus and a key to the species of Anotylus sculpturatus group, mainly focused on Chinese fauna, are also included in the paper, so as to benefit the classification and identification in the future.

Objective. This research provides objective and quantitative parameters of the traditional Chinese medicine (TCM) pulse conditions for distinguishing between patients with the coronary heart disease (CHD) and normal people by using the proposed classification approach based on Hilbert-Huang transform (HHT) and random forest. Methods. The energy and the sample entropy features were extracted by applying the HHT to TCM pulse by treating these pulse signals as time series. By using the random forest classifier, the extracted two types of features and their combination were, respectively, used as input data to establish classification model. Results. Statistical results showed that there were significant differences in the pulse energy and sample entropy between the CHD group and the normal group. Moreover, the energy features, sample entropy features, and their combination were inputted as pulse feature vectors; the corresponding average recognition rates were 84%, 76.35%, and 90.21%, respectively. Conclusion. The proposed approach could be appropriately used to analyze pulses of patients with CHD, which can lay a foundation for research on objective and quantitative criteria on disease diagnosis or Zheng differentiation.

By using the random forest classifier, the extracted two types of features and their combination were, respectively, used as input data to establish classification model. Results. Statistical results showed that there were significant differences in the pulse energy and sample entropy between the CHD group and the normal group. Moreover, the energy features, sample entropy features, and their combination were inputted as pulse feature vectors; the corresponding average recognition rates were 84%, 76.35%, and 90.21%, respectively. Conclusion. The proposed approach could be appropriately used to analyze pulses of patients with CHD, which can lay a foundation for research on objective and quantitative criteria on disease diagnosis or Zheng differentiation.

Aurora is a very important geophysical phenomenon in the high latitudes of Arctic and Antarctic regions, and it is important to make a comparative study of the auroral morphology between the two hemispheres. Based on the morphological characteristics of the four labeled dayside discrete auroral types (auroral arc, drapery corona, radial corona and hot-spot aurora) on the 8001 dayside auroral images at the Chinese Arctic Yellow River Station in 2003, and by extracting the local binary pattern (LBP) features and using a k-nearest classifier, this paper performs an automatic classification of the 65 361 auroral images of the Chinese Arctic Yellow River Station during 2004-2009 and the 39 335 auroral images of the South Pole Station between 2003 and 2005. Finally, it obtains the occurrence distribution of the dayside auroral morphology in the Northern and Southern Hemisphere. The statistical results indicate that the four dayside discrete auroral types present a similar occurrence distribution between the two stations. To the best of our knowledge, we are the first to report statistical comparative results of dayside auroral morphology distribution between the Northern and Southern Hemisphere.

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.

Reduction gonioplasty is very popular in East Asia. However, there has been little quantitative criteria for mandibular angle classification or aesthetics. The aim of this study was to investigate the quantitative differences of mandibular angle types and determine the morphologic features of mandibular angle in attractive women. We created a database of skull computed tomography and standardized frontal and lateral photographs of 96 Chinese female adults. Mandibular angle was classified into 3 groups, namely, extraversion, introversion, and healthy group, based on the position of gonion. We used a 5-point Likert scale to quantify attractiveness based on photographs. Those who scored 4 or higher were defined as attractive women. Three types of computed tomography measurements of the mandible were taken, including 4 distances, 4 angles, and 3 proportions. Discriminant analysis was applied to establish a mathematic model for mandibular angle aesthetics evaluation. Significant differences were observed between the different types of mandibular angle in lower facial width (Gol-Gor), mandibular angle (Co-Go-Me), and gonion divergence angle (Gol-Me-Gor) (P < 0.01). Chinese attractive women had a mandibular angle of 123.913 ± 2.989 degrees, a FH-MP of 27.033 ± 2.695 degrees, and a Go-Me/Co-Go index of 2.0. The "healthy" women had a mandibular angle of 116.402 ± 5.373 degrees, a FH-MP of 19.556 ± 5.999 degrees, and a Go-Me/Co-Go index of 1.6. The estimated Fisher linear discriminant function for the identification of attractive women was as follows: Y = -0.1516X1(Co-Go) + 0.128X2(Go-Me) + 0.04936X3(Co-Go-Me) +0.0218X4(FH-MP). Our study quantified the differences of mandibular angle types and identified the morphological features of mandibular angle in attractive Chinese female adults. Our results could assist plastic surgeons in presurgical designing of new aesthetic gonion and help to evaluate lower face aesthetics.

Product insights beyond hedonic responses are increasingly sought and include emotional associations. Various word-based questionnaires for direct measurement exist and an emoji variant was recently proposed. Herein, emotion words are replaced with emoji conveying a range of emotions. Further assessment of emoji questionnaires is needed to establish their relevance in food-related consumer research. Methodological research contributes hereto and in the present research the effects of question wording and response format are considered. Specifically, a web study was conducted with Chinese consumers (n=750) using four seafood names as stimuli (mussels, lobster, squid and abalone). Emotional associations were elicited using 33 facial emoji. Explicit reference to "how would you feel?" in the question wording changed product emoji profiles minimally. Consumers selected only a few emoji per stimulus when using CATA (check-all-that-apply) questions, and layout of the CATA question had only a small impact on responses. A comparison of CATA questions with forced yes/no questions and RATA (rate-all-that-apply) questions revealed an increase in frequency of emoji use for yes/no questions, but not a corresponding improvement in sample discrimination. For the stimuli in this research, which elicited similar emotional associations, RATA was probably the best methodological choice, with 8.5 emoji being used per stimulus, on average, and increased sample discrimination relative to CATA (12% vs. 6-8%). The research provided additional support for the potential of emoji surveys as a method for measurement of emotional associations to foods and beverages and began contributing to development of guidelines for implementation.

The methodological basis and procedures for determination of Chinese normalization references and weighting factors according to the EDIP-method is described. According to Chinese industrial development intensity and population density, China was divided into three regions and the normalization references for each region were calculated on the basis of an inventory of all of the region's environmental emissions in 1990. The normalization reference was determined as the total environmental impact potential for the area in question in 1990 (EP(j)90) divided by the population. The weighting factor was determined as the normalization reference (ER(j)90) divided by society's target contribution in the year 2000 based on Chinese political reduction plans, ER(j)T2000. This paper presents and discuss results obtained for eight different environmental impact categories relevant for China: global warming, stratospheric ozone depletion, acidification, nutrient enrichment, photochemical ozone formation and generation of bulk waste, hazardous waste and slag and ashes.

Cross-cultural research on children's theory of mind (ToM) understanding has raised questions about its developmental sequence and relationship with executive function (EF). The current study examined how ToM develops (using the tasks from Wellman & Liu, 2004) in relation to 2 EF skills (conflict inhibition, working memory) in 997 Chinese preschoolers (ages 3, 4, 5) in Chengdu, China. Compared with prior research with other Chinese and non-Chinese children, some general patterns in development were replicated in this sample. However, the children showed culture-specific reversals in the developmental sequence of ToM. For example, Chengdu children performed differently on the 2 false-belief tasks that were thought to be equivalent. Furthermore, conflict inhibition as well as working memory uniquely predicted ToM performance. We discuss the issues of ToM development as they relate to test items and cross-cultural--and subcultural--differences. (c) 2016 APA, all rights reserved).

The Associations and Correlations Between Self-reported Health and Neighborhood Cohesion and Disorder in a Community-dwelling U.S. Chinese Population.

Characteristics of neighborhood have been found to be associated with physical and psychological health status of older adults, especially in relationship to social dynamics like cohesion and disorder. This study aims to examine correlations and associations between sociodemographic characteristics, self-reported health status, cohesion, and disorder among Chinese older adults in the greater Chicago area. The Population Study of Chinese Elderly in Chicago is a cross-sectional, population-based study with community-dwelling Chinese older adults aged 60 and older, recruited through a community-based participatory research approach. Cohesion was measured through six questions; disorder was measured through eight questions. Correlation and regression analyses were conducted using SAS. Among 3,158 participants enrolled in the study, 92.3% reported any neighborhood cohesion; 69.8% reported any neighborhood disorder. After controlling for age, sex, education, income, marital status, living arrangement, number of children, years in the community, years in the United States, country of origin, language preference, and location, a higher level of cohesion is associated with higher quality of life (odds ratio [OR]: 1.25, 95% confidence interval [CI]: 1.13, 1.39) and a higher level of disorder is associated with lower overall health status (OR: 0.97, 95% CI: 0.95, 0.99) and lower quality of life (OR: 0.96, 95% CI: 0.95, 0.98). Our findings suggest that neighborhood cohesion and neighborhood disorder are correlated to the health of U.S. Chinese older adults. Future longitudinal research should examine the relationship between community characteristics, both structural and social, and health-related outcomes. © The Author 2016.

To describe family involvement in decision making for primary treatment in Chinese-American women with early-stage breast cancer. Qualitative data were collected in 2003 from semi-structured questions in interviews with a sample of Chinese-American (ChA) women with breast cancer, who were recruited from the metropolitan New York area. Responses to the questions were written in Chinese immediately during the interview and read back to the subject for accuracy and validation. Content analysis was used to inductively code and analyze the data to generate themes. The participants consisted of 123 ChA women with early stage breast cancer with a mean age of 48.7 years (±9.3) and who had lived in the United States a median of 13.6 years. Support and Caring was the major theme that described family involvement in the breast cancer decision-making process. Gathering Information, Being There, Navigating the Health Care System, Maintaining Family Life and Making the Decision described the aspects of family support in the process. The majority of women described the treatment decision making as a collaborative supportive process with the family, but limited English fluency, strong opinions, lack of a shared perspective, distant living proximity and competing work responsibilities of family members were stressful for the women and perceived as non-supportive. Family involvement in health care decision making is culturally embedded in Asian populations. Culturally sensitive patient and family consultation strategies are needed to assist informed treatment decision making in Chinese-American women diagnosed with breast cancer.

Toward functional classification of neuronal types.

PubMed

Sharpee, Tatyana O

2014-09-17

How many types of neurons are there in the brain? This basic neuroscience question remains unsettled despite many decades of research. Classification schemes have been proposed based on anatomical, electrophysiological, or molecular properties. However, different schemes do not always agree with each other. This raises the question of whether one can classify neurons based on their function directly. For example, among sensory neurons, can a classification scheme be devised that is based on their role in encoding sensory stimuli? Here, theoretical arguments are outlined for how this can be achieved using information theory by looking at optimal numbers of cell types and paying attention to two key properties: correlations between inputs and noise in neural responses. This theoretical framework could help to map the hierarchical tree relating different neuronal classes within and across species. Copyright © 2014 Elsevier Inc. All rights reserved.

Theory of Mind (ToM) refers to the ability to compute and attribute mental states to ourselves and other people. It is currently unclear whether ToM abilities are universal or whether they can be culturally influenced. To address this question, this research explored potential differences in engagement of ToM processes between two different cultures, Western (individualist) and Chinese (collectivist), using a sample of healthy adults. Participants completed a computerised false-belief task, in which they attributed beliefs to either themselves or another person, in a matched design, allowing direct comparison between "Self"- and "Other"-oriented conditions. Results revealed that both native-English speakers and native-Chinese individuals responded significantly faster to self-oriented than other-oriented questions. Results also showed that when a trial required a "perspective-shift," participants from both cultures were slower to shift from Self-to-Other than from Other-to-Self. Results indicate that despite differences in collectivism scores, culture does not influence task performance, with similar results found for both Western and non-Western participants, suggesting core and potentially universal similarities in the ToM mechanism across these two cultures.

2013-02-01

Classification is a central endeavor in every scientific field of work. Classification in biology, however, is distinct from classification in other fields of science in a number of ways. Thus, understanding how biological classification works is an important element in understanding the nature of biological science. In the present paper, I discuss a number of philosophical issues that are characteristic for classification in biological science, paying special attention to questions related to science education. My aims are (1) to provide science educators and others concerned with the teaching of biology with an accessible overview of the philosophy of biological classification and (2) to show how knowledge of the philosophy of classification can play an important role in science teaching.

In this research, the transparent glaze layers of Chinese porcelain samples were investigated. Depending on the production period, these samples can be divided into two groups: the samples of group A dating from the Kangxi period (1661-1722), and the samples of group B produced under emperor Qianlong (1735-1795). Due to the specific sample preparation method and the small spot size of the X-ray beam, investigation of the transparent glaze layers is enabled. Despite the many existing research papers about glaze investigations of ceramics and/or porcelain ware, this research reveals new insights into the glaze composition and structure of Chinese porcelain samples. In this paper it is demonstrated, using micro-X-ray Fluorescence (μ-XRF) spectrometry, multivariate data analysis and statistical analysis (Hotelling's T-Square test) that the transparent glaze layers of the samples of groups A and B are significantly different (95% confidence level). Calculation of the Seger formulas, enabled classification of the glazes. Combining all the information, the difference in composition of the Chinese porcelain glazes of the Kangxi period and the Qianlong period can be demonstrated.

[A complexity analysis of Chinese herbal property theory: the multiple formations of herbal property].

Chinese herbal property theory (CHPT) is the fundamental characteristic of Chinese materia medica different from modern medicines. It reflects the herbal properties associated with efficacy and formed the early framework of four properties and five flavors in Shennong's Classic of Materia Medica. After the supplement and improvement of CHPT in the past thousands of years, it has developed a theory system including four properties, five flavors, meridian entry, direction of medicinal actions (ascending, descending, floating and sinking) and toxicity. However, because of the influence of philosophy about yin-yang theory and five-phase theory and the difference of cognitive approach and historical background at different times, CHPT became complex. One of the complexity features was the multiple methods for determining herbal property, which might include the inference from herbal efficacy, the thought of Chinese Taoist School and witchcraft, the classification thinking according to manifestations, etc. Another complexity feature was the multiselection associations between herbal property and efficacy, which indicated that the same property could be inferred from different kinds of efficacy. This paper analyzed these complexity features and provided the importance of cognitive approaches and efficacy attributes corresponding to certain herbal property in the study of CHPT.

Classification and prediction of rice wines with different marked ages by using a voltammetric electronic tongue.

2011-08-15

A voltammetric electronic tongue (VE-tongue) was developed to discriminate the difference between Chinese rice wines in this research. Three types of Chinese rice wine with different marked ages (1, 3, and 5 years) were classified by the VE-tongue by principal component analysis (PCA) and cluster analysis (CA). The VE-tongue consisted of six working electrodes (gold, silver, platinum, palladium, tungsten, and titanium) in a standard three-electrode configuration. The multi-frequency large amplitude pulse voltammetry (MLAPV), which consisted of four segments of 1 Hz, 10 Hz, 100 Hz, and 1000 Hz, was applied as the potential waveform. The three types of Chinese rice wine could be classified accurately by PCA and CA, and some interesting regularity is shown in the score plots with the help of PCA. Two regression models, partial least squares (PLS) and back-error propagation-artificial neural network (BP-ANN), were used for wine age prediction. The regression results showed that the marked ages of the three types of Chinese rice wine were successfully predicted using PLS and BP-ANN. Copyright © 2011 Elsevier B.V. All rights reserved.

The safety of Chinese patent medicine has become a focus of social. It is necessary to carry out work on post-marketing clinical safety evaluation for Chinese patent medicine. However, there have no criterions to guide the related research, it is urgent to set up a model and method to guide the practice for related research. According to a series of clinical research, we put forward some views, which contained clear and definite the objective and content of clinical safety evaluation, the work flow should be determined, make a list of items for safety evaluation project, and put forward the three level classification of risk control. We set up a model of post-marketing clinical safety evaluation for Chinese patent medicine. Based this model, the list of items can be used for ranking medicine risks, and then take steps for different risks, aims to lower the app:ds:risksrisk level. At last, the medicine can be managed by five steps in sequence. The five steps are, collect risk signal, risk recognition, risk assessment, risk management, and aftereffect assessment. We hope to provide new ideas for the future research.

Optimal periods during early development facilitate the formation of perceptual representations, laying the framework for future learning. A crucial question is whether such early representations are maintained in the brain over time without continued input. Using functional MRI, we show that internationally adopted (IA) children from China, exposed exclusively to French since adoption (mean age of adoption, 12.8 mo), maintained neural representations of their birth language despite functionally losing that language and having no conscious recollection of it. Their neural patterns during a Chinese lexical tone discrimination task matched those observed in Chinese/French bilinguals who have had continual exposure to Chinese since birth and differed from monolingual French speakers who had never been exposed to Chinese. They processed lexical tone as linguistically relevant, despite having no Chinese exposure for 12.6 y, on average, and no conscious recollection of that language. More specifically, IA participants recruited left superior temporal gyrus/planum temporale, matching the pattern observed in Chinese/French bilinguals. In contrast, French speakers who had never been exposed to Chinese did not recruit this region and instead activated right superior temporal gyrus. We show that neural representations are not overwritten and suggest a special status for language input obtained during the first year of development.

Chinese paleontology and the reception of Darwinism in early twentieth century.

PubMed

Yu, Xiaobo

2017-12-01

The paper examines the social, cultural and disciplinary factors that influenced the reception and appropriation of Darwinism by China's first generation paleontologists. Darwinism was mixed with Social Darwinism when first introduced to China, and the co-option of Darwinian phrases for nationalistic awakening obscured the scientific essence of Darwin's evolutionary theory. First generation Chinese paleontologists started their training in 1910s-1920s. They quickly asserted their professional identity by successfully focusing on morphology, taxonomy and biostratigraphy. Surrounded by Western paleontologists with Lamarckian or orthogenetic leanings, early Chinese paleontologists enthusiastically embraced evolution and used fossils as factual evidence; yet not enough attention was given to mechanistic evolutionary studies. The 1940s saw the beginning of a new trend for early Chinese paleontologists to incorporate more biological and biogeographical components in their work, but external events such as the dominance of Lysenkoism in the 1950s made the Modern Synthesis pass by without being publicly noticed in Chinese paleontology. Characterized by the larger goal of using science for nation building and by the utilitarian approach favoring local sciences, the reception and appropriation of Darwinism by first generation Chinese paleontologists raise important questions for studying the indigenizing efforts of early Chinese scientists to appropriate Western scientific theories.

2004-02-01

Online handwriting recognition is gaining renewed interest owing to the increase of pen computing applications and new pen input devices. The recognition of Chinese characters is different from western handwriting recognition and poses a special challenge. To provide an overview of the technical status and inspire future research, this paper reviews the advances in online Chinese character recognition (OLCCR), with emphasis on the research works from the 1990s. Compared to the research in the 1980s, the research efforts in the 1990s aimed to further relax the constraints of handwriting, namely, the adherence to standard stroke orders and stroke numbers and the restriction of recognition to isolated characters only. The target of recognition has shifted from regular script to fluent script in order to better meet the requirements of practical applications. The research works are reviewed in terms of pattern representation, character classification, learning/adaptation, and contextual processing. We compare important results and discuss possible directions of future research.

Multi-Pixel Simultaneous Classification of PolSAR Image Using Convolutional Neural Networks

2018-01-01

Convolutional neural networks (CNN) have achieved great success in the optical image processing field. Because of the excellent performance of CNN, more and more methods based on CNN are applied to polarimetric synthetic aperture radar (PolSAR) image classification. Most CNN-based PolSAR image classification methods can only classify one pixel each time. Because all the pixels of a PolSAR image are classified independently, the inherent interrelation of different land covers is ignored. We use a fixed-feature-size CNN (FFS-CNN) to classify all pixels in a patch simultaneously. The proposed method has several advantages. First, FFS-CNN can classify all the pixels in a small patch simultaneously. When classifying a whole PolSAR image, it is faster than common CNNs. Second, FFS-CNN is trained to learn the interrelation of different land covers in a patch, so it can use the interrelation of land covers to improve the classification results. The experiments of FFS-CNN are evaluated on a Chinese Gaofen-3 PolSAR image and other two real PolSAR images. Experiment results show that FFS-CNN is comparable with the state-of-the-art PolSAR image classification methods. PMID:29510499

Number line estimation and mental addition: examining the potential roles of language and education.

Laski, Elida V; Yu, Qingyi

2014-01-01

This study investigated the relative importance of language and education to the development of numerical knowledge. Consistent with previous research suggesting that counting systems that transparently reflect the base-10 system facilitate an understanding of numerical concepts, Chinese and Chinese American kindergartners' and second graders' number line estimation (0-100 and 0-1000) was 1 to 2 years more advanced than that of American children tested in previous studies. However, Chinese children performed better than their Chinese American peers, who were fluent in Chinese but had been educated in America, at kindergarten on 0-100 number lines, at second grade on 0-1000 number lines, and at both time points on complex addition problems. Overall, the pattern of findings suggests that educational approach may have a greater influence on numerical development than the linguistic structure of the counting system. The findings also demonstrate that, despite generating accurate estimates of numerical magnitude on 0-100 number lines earlier, it still takes Chinese children approximately 2 years to demonstrate accurate estimates on 0-1000 number lines, which raises questions about how to promote the mapping of knowledge across numerical scales.

The study was to compare treatment preference, efficacy, and tolerability of sildenafil citrate (sildenafil) and tadalafil for treating erectile dysfunction (ED) in Chinese men naïve to phosphodiesterase 5 (PDE5) inhibitor therapies. This multicenter, randomized, open-label, crossover study evaluated whether Chinese men with ED preferred 20-mg tadalafil or 100-mg sildenafil. After a 4 weeks baseline assessment, 383 eligible patients were randomized to sequential 20-mg tadalafil per 100-mg sildenafil or vice versa for 8 weeks respectively and then chose which treatment they preferred to take during the 8 weeks extension. Primary efficacy was measured by Question 1 of the PDE5 Inhibitor Treatment Preference Questionnaire (PITPQ). Secondary efficacy was analyzed by PITPQ Question 2, the International Index of Erectile Function (IIEF) erectile function (EF) domain, sexual encounter profile (SEP) Questions 2 and 3, and the Drug Attributes Questionnaire. Three hundred and fifty men (91%) completed the randomized treatment phase. Two hundred and forty-two per 350 (69.1%) patients preferred 20-mg tadalafil, and 108/350 (30.9%) preferred 100-mg sildenafil (P < 0.001) as their treatment in the 8 weeks extension. Ninety-two per 242 (38%) patients strongly preferred tadalafil and 37/108 (34.3%) strongly the preferred sildenafil. The SEP2 (penetration), SEP3 (successful intercourse), and IIEF-EF domain scores were improved in both tadalafil and sildenafil treatment groups. For patients who preferred tadalafil, getting an erection long after taking the medication was the most reported reason for tadalafil preference. The only treatment-emergent adverse event reported by > 2% of men was headache. After tadalafil and sildenafil treatments, more Chinese men with ED naïve to PDE5 inhibitor preferred tadalafil. Both sildenafil and tadalafil treatments were effective and safe. PMID:25370206

The study was to compare treatment preference, efficacy, and tolerability of sildenafil citrate (sildenafil) and tadalafil for treating erectile dysfunction (ED) in Chinese men naοve to phosphodiesterase 5 (PDE5) inhibitor therapies. This multicenter, randomized, open-label, crossover study evaluated whether Chinese men with ED preferred 20-mg tadalafil or 100-mg sildenafil. After a 4 weeks baseline assessment, 383 eligible patients were randomized to sequential 20-mg tadalafil per 100-mg sildenafil or vice versa for 8 weeks respectively and then chose which treatment they preferred to take during the 8 weeks extension. Primary efficacy was measured by Question 1 of the PDE5 Inhibitor Treatment Preference Questionnaire (PITPQ). Secondary efficacy was analyzed by PITPQ Question 2, the International Index of Erectile Function (IIEF) erectile function (EF) domain, sexual encounter profile (SEP) Questions 2 and 3, and the Drug Attributes Questionnaire. Three hundred and fifty men (91%) completed the randomized treatment phase. Two hundred and forty-two per 350 (69.1%) patients preferred 20-mg tadalafil, and 108/350 (30.9%) preferred 100-mg sildenafil (P < 0.001) as their treatment in the 8 weeks extension. Ninety-two per 242 (38%) patients strongly preferred tadalafil and 37/108 (34.3%) strongly the preferred sildenafil. The SEP2 (penetration), SEP3 (successful intercourse), and IIEF-EF domain scores were improved in both tadalafil and sildenafil treatment groups. For patients who preferred tadalafil, getting an erection long after taking the medication was the most reported reason for tadalafil preference. The only treatment-emergent adverse event reported by > 2% of men was headache. After tadalafil and sildenafil treatments, more Chinese men with ED naοve to PDE5 inhibitor preferred tadalafil. Both sildenafil and tadalafil treatments were effective and safe.

This study attempted to understand gender differences in knowledge of mental illness, preference for professional help, and medications and treatment methods among Australians of Chinese-speaking background. This study adopted a cluster convenience sampling method in which subjects were taken from the four major areas in cosmopolitan Melbourne where most Chinese people are living. A total of 200 Chinese-speaking Australians participated in the study. They were presented with two vignettes describing an individual with acute depression or acute schizophrenia and then questions were asked to assess their understanding of the conditions, preference for professional help, medications and treatment methods. More female than male respondents could correctly identify the conditions in the two vignettes. Female participants also perceived medications to be relatively more harmful than their male counterparts. In contrast, there were significantly more males than females who adhered to traditional views on the causation of mental illness; had significantly higher percentages of endorsement of 'deal with it alone'; believed 'traditional Chinese medical doctor' and 'Chinese herbal medicines' to be helpful to the person in the schizophrenia vignette; and significantly endorsed 'psychiatric ward', 'electro-convulsive treatment', 'changing fungshui' and 'traditional Chinese worship' to be helpful for the persons in both vignettes. A combination of factors, which included age, duration of migration and traditional Chinese cultural values, were put forward to explain the above differences. Campaigns to improve the mental health literacy of Chinese-speaking Australians must take into account the gender differences between male and female Chinese-speaking Australians so that culturally relevant and gender-specific education programmes can be developed.

The herbs used as the material for traditional Chinese medicine are always planted in the mountainous area where the natural environment is suitable. As the mountain terrain is complex and the distribution of planting plots is scattered, the traditional survey method is difficult to obtain accurate planting area. It is of great significance to provide decision support for the conservation and utilization of traditional Chinese medicine resources by studying the method of extraction of Chinese herbal medicine planting area based on remote sensing and realizing the dynamic monitoring and reserve estimation of Chinese herbal medicines. In this paper, taking the Panax notoginseng plots in Wenshan prefecture of Yunnan province as an example, the China-made GF-1multispectral remote sensing images with a 16 m×16 m resolution were obtained. Then, the time series that can reflect the difference of spectrum of P. notoginseng shed and the background objects were selected to the maximum extent, and the decision tree model of extraction the of P. notoginseng plots was constructed according to the spectral characteristics of the surface features. The results showed that the remote sensing classification method based on the decision tree model could extract P. notoginseng plots in the study area effectively. The method can provide technical support for extraction of P. notoginseng plots at county level. Copyright© by the Chinese Pharmaceutical Association.

Descriptions of vestibular migraine and Menière's disease in Greek and Chinese antiquity.

PubMed

Huppert, Doreen; Brandt, Thomas

2017-04-01

Background Vestibular migraine and Menière's disease are two types of episodic vertigo syndromes that were already observed in Greek and Chinese antiquity. Descriptions first appeared in the work of the classical Greek physician Aretaeus of Cappadocia, who lived in the 2nd century AD, and in Huangdi Neijing, a seminal medical source in the Chinese Medical Classics, written between the 2nd century BC and the 2nd century AD. Aim The aim of this paper is to search in Aretaeus' book De causis et signis acutorum et chronicorum morborum and in Huangdi Neijing for descriptions of vertigo co-occurring with headache or ear symptoms that resemble current classifications of vestibular migraine or Menière's disease. Results Aretaeus describes a syndrome combining headache, vertigo, visual disturbance, oculomotor phenomena, and nausea that resembles the symptoms of vestibular migraine. In the Chinese book Huangdi Neijing the Yellow Thearch mentions the co-occurrence of episodic dizziness and a ringing noise of the ears that recalls an attack of Menière's disease. Conclusions The descriptions of these two conditions in Greek and Chinese antiquity are similar to the vertigo syndromes currently classified as vestibular migraine and Menière's disease. In clinical practice it may be difficult to clearly differentiate between them, and they may also co-occur.

The latest global financial tsunami and its follow-up global economic recession has uncovered the crucial impact of housing markets on financial and economic systems. The Chinese stock market experienced a marked fall during the global financial tsunami and China’s economy has also slowed down by about 2%-3% when measured in GDP. Nevertheless, the housing markets in diverse Chinese cities seemed to continue the almost nonstop mania for more than 10 years. However, the structure and dynamics of the Chinese housing market are less studied. Here, we perform an extensive study of the Chinese housing market by analyzing 10 representative key cities based on both linear and nonlinear econophysical and econometric methods. We identify a common collective driving force which accounts for 96.5% of the house price growth, indicating very high systemic risk in the Chinese housing market. The 10 key cities can be categorized into clubs and the house prices of the cities in the same club exhibit an evident convergence. These findings from different methods are basically consistent with each other. The identified city clubs are also consistent with the conventional classification of city tiers. The house prices of the first-tier cities grow the fastest and those of the third- and fourth-tier cities rise the slowest, which illustrates the possible presence of a ripple effect in the diffusion of house prices among different cities.

To assess vision-related quality of life in patients with ocular chemical burns by the application of the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25). Eighty-seven patients with ocular chemical burns were enrolled in the study from January 1 through May 31, 2010. Apart from the collection of sociodemographic and clinical data, NEI VFQ-25 with an additional appendix question, being translated to Chinese, was administered to all subjects. Main outcome measures were comparison of the NEI VFQ-25 subscale item scores among subgroups and multivariate analysis of the NEI VFQ-25 subscale scores. Fifty-five subjects were bilaterally burned and the rest were unilaterally injured. The mean age of enrolled subjects was 39.4 ± 11.6 years, with the majority being male (98.9%) and worker (77.0%); the mean composite score of all subjects was 40.4 ± 23.8. The composite score and majority subscale scores of binocularly injured patients were significantly lower than those of monocularly injured patients. Further comparisons among groups divided by either clinical severity classification or best-corrected visual acuity (BCVA) produced similar results. The BCVA of both the better-seeing eye and the worse-seeing eye strongly correlated with the NEI VFQ-25 composite score (ρ = 0.664 and 0.498, both P = 0.000). Multivariate regression analysis revealed that the VFQ-25 composite score correlated significantly with the following independent variables: BCVA of the better-seeing eye and the worse-seeing eye, the injury classification of the less severely injured eye, and correct and immediate irrigation after injury as well. Ocular chemical burns have a significant and extensive impact on patients' visual function outcomes and vision-related quality of life.

What are the differences between the occurrence of menopausal symptoms in German women, migrant Chinese women in Germany and Chinese women in their native country? Can these potential discrepancies be explained by sociocultural differences? What are the differences in menopausal symptoms in connection with the consumption of soya? Cross-sectional study 2005-2008. Survey of three groups of women aged between 45 and 60 years (native German women in Berlin, migrant Chinese women in several German cities, Chinese women in Beijing) with an evaluated set of questionnaires surveying socio-demographic data, use of hormone therapy, migration/acculturation, MRS II and other areas. A total of 2,109 questionnaires were sent out and a 41 % response rate was achieved, although this varied greatly across the three individual study groups. The results of the MRS II factor analysis were almost identical for German women and migrant Chinese women, but there were some differences in content compared to the Chinese study group. Chinese women surveyed in Beijing reported severe symptoms significantly less frequently in all three symptom groups (factors) of MRS II than the German women and the migrant Chinese women, but the values from the German women and migrant Chinese women surveyed are relatively similar. In all three study groups there are no significant differences in the stated severity of the symptoms, regardless of whether soya is consumed frequently or less frequently. The question whether the differences found are solely cultural or migration-related must be examined in further studies. The special experiences and situation in life of migrant women should be taken into particular account by attending physicians during the care and treatment of women in this phase of life.

Chinese kale, a vegetable of the cruciferous family, is a popular crop in southern China and Southeast Asia due to its high glucosinolate content and nutritional qualities. However, there is little research on the molecular genetics and genes involved in glucosinolate metabolism and its regulation in Chinese kale. In this study, we sequenced and characterized the transcriptomes and expression profiles of genes expressed in 11 tissues of Chinese kale. A total of 216 million 150-bp clean reads were generated using RNA-sequencing technology. From the sequences, 98,180 unigenes were assembled for the whole plant, and 49,582~98,423 unigenes were assembled for each tissue. Blast analysis indicated that a total of 80,688 (82.18%) unigenes exhibited similarity to known proteins. The functional annotation and classification tools used in this study suggested that genes principally expressed in Chinese kale, were mostly involved in fundamental processes, such as cellular and molecular functions, the signal transduction, and biosynthesis of secondary metabolites. The expression levels of all unigenes were analyzed in various tissues of Chinese kale. A large number of candidate genes involved in glucosinolate metabolism and its regulation were identified, and the expression patterns of these genes were analyzed. We found that most of the genes involved in glucosinolate biosynthesis were highly expressed in the root, petiole, and in senescent leaves. The expression patterns of ten glucosinolate biosynthetic genes from RNA-seq were validated by quantitative RT-PCR in different tissues. These results provided an initial and global overview of Chinese kale gene functions and expression activities in different tissues. PMID:28228764

We tested the use of otolith shape analysis to discriminate between species and stocks of five goby species ( Ctenotrypauchen chinensis, Odontamblyopus lacepedii, Amblychaeturichthys hexanema, Chaeturichthys stigmatias, and Acanthogobius hasta) found in northern Chinese coastal waters. The five species were well differentiated with high overall classification success using shape indices (83.7%), elliptic Fourier coefficients (98.6%), or the combination of both methods (94.9%). However, shape analysis alone was only moderately successful at discriminating among the four stocks (Liaodong Bay, LD; Bohai Bay, BH; Huanghe (Yellow) River estuary HRE, and Jiaozhou Bay, JZ stocks) of A. hasta (50%-54%) and C. stigmatias (65.7%-75.8%). For these two species, shape analysis was moderately successful at discriminating the HRE or JZ stocks from other stocks, but failed to effectively identify the LD and BH stocks. A large number of otoliths were misclassified between the HRE and JZ stocks, which are geographically well separated. The classification success for stock discrimination was higher using elliptic Fourier coefficients alone (70.2%) or in combination with shape indices (75.8%) than using only shape indices (65.7%) in C. stigmatias whereas there was little difference among the three methods for A. hasta. Our results supported the common belief that otolith shape analysis is generally more effective for interspecific identification than intraspecific discrimination. Moreover, compared with shape indices analysis, Fourier analysis improves classification success during inter- and intra-species discrimination by otolith shape analysis, although this did not necessarily always occur in all fish species.

Objectives To investigate why first-generation Chinese immigrants with diabetes have difficulty obtaining, processing and understanding diabetes related information despite the existence of translated materials and translators. Design This qualitative study employed purposive sampling. Six focus groups and two individual interviews were conducted. Each group discussion lasted approximately 90 min and was guided by semistructured and open-ended questions. Setting Data were collected in two community health centres and one elderly retirement village in Los Angeles, California. Participants 29 Chinese immigrants aged ≥45 years and diagnosed with type 2 diabetes for at least 1 year. Results Eight key themes were found to potentially affect Chinese immigrants' capacity to obtain, communicate, process and understand diabetes related health information and consequently alter their decision making in self-care. Among the themes, three major categories emerged: cultural factors, structural barriers, and personal barriers. Conclusions Findings highlight the importance of cultural sensitivity when working with first-generation Chinese immigrants with diabetes. Implications for health professionals, local community centres and other potential service providers are discussed. PMID:25406155

Chinese attitudes towards sexual minorities in Hong Kong: Implications for mental health.

PubMed

Kwok, Diana K; Wu, Joseph

2015-01-01

Intolerant attitudes and sexual prejudice against sexual minorities (lesbian, gay, bisexual, and questioning/queer-LGBQ) has been a long-standing global concern. In this article, Chinese attitudes towards sexual minorities are examined with reference to the cultural context in Hong Kong, a place where the East has intermingled with the West for over a century. Chinese sexuality manifested in Hong Kong is a mix of Confucian ideology and Christian thought. Traditional Confucian values of xiao (filial piety) and conventional religious thoughts of Christianity together influence Chinese attitudes towards sexual minorities. Though many governmental policies have been put in place and numerous laws have been enacted to protect the human rights of underprivileged and disadvantaged groups over the past few decades, sexual minorities are frequently being excluded from most of these protections. In Hong Kong, sexual prejudice exists not only among the general public, but also among educators and mental health professionals. Thus, Chinese sexual minorities experience sexual prejudice and minority stress in Hong Kong under unique cultural circumstances. This calls for inclusive policies and an embracing attitude towards sexual minorities so their mental health will not suffer.

Objective: To review the worldwide studies on natural history models among colorectal cancer (CRC), and to inform building a Chinese population-specific CRC model and developing a platform for further evaluation of CRC screening and other interventions in population in China. Methods: A structured literature search process was conducted in PubMed and the target publication dates were from January 1995 to December 2014. Information about classification systems on both colorectal cancer and precancer on corresponding transition rate, were extracted and summarized. Indicators were mainly expressed by the medians and ranges of annual progression or regression rate. Results: A total of 24 studies were extracted from 1 022 studies, most were from America ( n =9), but 2 from China including 1 from the mainland area, mainly based on Markov model ( n =22). Classification systems for adenomas included progression risk ( n =9) and the sizes of adenoma ( n =13, divided into two ways) as follows: 1) Based on studies where adenoma was risk-dependent, the median annual transition rates, from ' normal status' to ' non-advanced adenoma', 'non-advanced' to ' advanced' and ' advanced adenoma' to CRC were 0.016 0 (range: 0.002 2-0.020 0), 0.020 (range: 0.002-0.177) and 0.044 (range: 0.005-0.063), respectively. 2) Median annual transition rates, based on studies where adenoma were classified by sizes, into <10 mm and ≥10 mm ( n =7), from ' normal' to adenoma <10 mm, from adenoma <10 mm to adenoma ≥10 mm and adenoma ≥ 10 mm to CRC, were 0.016 7 (range: 0.015 0-0.037 0), 0.020 (range: 0.015-0.035) and 0.040 0 (range: 0.008 5-0.050 0), respectively. 3) Median annual transition rates, based on studies where adenoma, were classified by sizes into diminutive (≤5 mm), small (6-9 mm) and large adenoma (≥10 mm) ( n =6), from ' normal' to diminutive adenoma,'diminutive' to ' small','small' to ' large', and large adenoma to CRC were 0.013 (range: 0.009-0.019), 0.043 (range: 0.020-0.085), 0.044 (range: 0.020-0.125) and 0.033 5 (range: 0.030-0.040), respectively. Staging system of CRC mainly included LRD (localized/regional/distant, n =10), Dukes' ( n =7) and TNM ( n =3). When using the LRD classification, the median annual transition rates from ' localized' to ' regional' and ' regional' to 'distant' were 0.28 (range: 0.20-0.33) and 0.40 (range: 0.24-0.63), respectively. Under the Dukes' classification, the median annual transition rates appeared as 0.583 (range: 0.050-0.910), 0.656 (range: 0.280-0.720) and 0.830 (range: 0.630-0.865) from Dukes' A to B, B to C and C to Dukes' D, respectively. Again, when using the TNM classification, very limited transition rate was reported. Serrated pathway was only described in one study. Conclusions: Studies on the natural history model of colorectal cancer was still limited worldwide. Adenoma seemed the most common status setting for precancer model, and the risk-dependent classification for adenoma was consistent with the most commonly used system in clinical practice as well as major cancer screening programs in China. Since the staging systems of cancers varied, and shortage of transition rates based on TNM classification (commonly used in China), there will be a challenge for building Chinese population-specific natural history model of colorectal cancer, information from other classification systems could be conditionally applied.

In this paper, we present an analysis of oracle bone characters for animals from a “cognitive” point of view. After some general remarks on oracle-bone characters presented in Sec. 1 and a short outline of the paper in Sec. 2, we collect various oracle-bone characters for animals from published resources in Sec. 3. In the next section, we begin analyzing a group of 60 ancient animal characters from www.zdic.net, a highly acclaimed internet dictionary of Chinese characters that is strictly based on historical sources, and introduce five categories of specific features regarding their (graphical) structure that will be used in Sec. 5 to associate corresponding feature vectors to these characters. In Sec. 6, these feature vectors will be used to investigate their dissimilarity in terms of a family of parameterized distance measures. And in the last section, we apply the SplitsTree method as encoded in the NeighborNet algorithms to construct a corresponding family of dissimilarity-based networks with the intention of elucidating how the ancient Chinese might have perceived the “animal world” in the late bronze age and to demonstrate that these pictographs reflect an intuitive understanding of this world and its inherent structure that predates its classification in the oldest surviving Chinese encyclopedia from approximately the third century BC, the Er Ya, as well as similar classification systems in the West by one to two millennia. We also present an English dictionary of 70 oracle bone characters for animals in Appendix A. In Appendix B, we list various variants of animal characters that were published in the Jia Gu Wen Bian (cf. 甲骨文编, A Complete Collection of Oracle Bone Characters, edited by the Institute of Archaeology of the Chinese Academy of Social Sciences, published by the Zhonghua Book Company in 1965). We recall the frequencies of the 521 most frequent oracle bone characters in Appendix C as reported in [T.

To develop a patient safety culture instrument for use in Chinese hospitals, we assessed the appropriateness of existing safety culture questionnaires used in the USA and Japan for Chinese respondents and identified new items and domains suitable to Chinese hospitals. Focus group study. Twenty-four physicians, nurses and other health-care workers from 11 hospitals in three Chinese cities. Three focus groups were conducted in 2010 to elicit information from hospital workers about their perceptions of the appropriateness and importance of each of 97 questionnaire items, derived from a literature review and an expert panel, characterizing hospital safety culture. understood the concepts of patient safety and safety culture and identified features associated with safe care. They judged that numerous questions from existing surveys were inappropriate, including 39 items that were dropped because they were judged unimportant, semantically redundant, confusing, ambiguous or inapplicable in Chinese settings. Participants endorsed eight new items and three additional dimensions addressing staff training, mentoring of new hires, compliance with rules and procedures, equipment availability and leadership walk-rounds they judged appropriate to assessing safety culture in Chinese hospitals. This process resulted in a 66-item instrument for testing in cognitive interviews, the next stage of survey development. Focus group participants provided important insights into the refinement of existing items and the construction of new items for measuring patient safety culture in Chinese hospitals. This is a necessary first step in producing a culturally appropriate instrument applicable to specific local contexts.

Would Confucius benefit from psychotherapy? The compatibility of cognitive behaviour therapy and Chinese values.

The purpose of the present paper is to explore the conceptual compatibility between cognitive behaviour therapy (CBT) and the common values of Chinese Culture. In order to address such a question, the distinctive processes attributed to CBT (e.g., teaching of skills, emphasis on homework, cognitive processes, present/future focus), as summarized in the meta-analysis by Blagys and Hilsenroth [(2002). Distinctive activities of cognitive-behavioral therapy: A review of the comparative psychotherapy process literature. Clinical Psychology Review, 22, 671-706], and the core values of Chinese Culture, determined through an integration of The Hofstede Project, [Hofstede, G.H. (1980). Culture's consequences: International differences in work related values. Beverly Hills: Sage]. The Chinese Value Survey [Chinese Culture Connection (1987). Chinese values and the search for culture-free dimensions of culture. Journal of Cross-Cultural Psychology, 18, 143-164]. The Schwartz Value Survey [Schwartz, S.H. (1994). Cultural dimensions of values: Towards an understanding of national differences. In Kim, U., Trandis, H.C., Katiticibasi, C., Choi, S.C., & Yoon, G. (eds.), Individualism and collectivism: Theory, method and application (pp. 85-119). Thousand Oaks, CA: Sage] were used. A strong degree of compatibility between the two was found and it is argued that rather than developing new indigenized therapies, with some structural changes to the processes of CBT, this therapy can be effective for Chinese clients. It is further proposed that Chinese clients may benefit from challenging their irrational cognitions that are bound up in their strict adherence to social norms. Future recommendations for increasing the compatibility of CBT to Chinese culture are discussed.

Sichuan is a province in the west of China with a population of 81.4 million. This is the first statistical report of central nervous system (CNS) tumors surgically treated and histologically diagnosed in a large Chinese population. All the patient data were obtained from 86 medical facilities, which covered the Sichuan province population. Data from patients who underwent surgery between 2008 and 2013 and corresponding histology samples were re-reviewed in the major pathology centers. All the CNS tumors were categorized according to International Classification of Diseases (ICD)-10 and ICD-O-3 classifications and reviewed manually. The tumor distribution was analyzed and stratified by gender, age, race, and tumor sites. Tumors in some ethnic minorities, such as the Tibetan people, also were analyzed. The final analytic dataset included 35,496 records. The top four histologic tumors were meningioma (28.51 %), pituitary adenoma (15.00 %), nerve sheath (13.77 %), and glioblastoma (11.82 %). There was a dramatically high incidence of malignant tumor in males. The median age at diagnosis ranged from 13 years (pineal region tumors) to 56 years (metastatic brain tumors). Most of the tumors in the insular lobe or cerebellum were low grade, whereas those in the thalamus or basal ganglia were likely to be high grade. The incidence of malignant tumors or high-grade gliomas in the Tibetans was significantly lower than in the Chinese Han population. This report is a preliminary statistical analysis of brain and spinal tumors in a large Chinese population and may serve as a useful resource for clinicians, researchers, and patients' families.

To validate the American College of Rheumatology Classification (ACR) Criteria (2012) for the diagnosis of primary Sjogren's syndrome in Chinese patients. All patients involved in this study came from the Department of Oral Medicine Peking University Stomatology Hospital. They were devided into two groups of pSS and non-pSS according to the diagnoses made by two experts. Both groups of the patients had completed medical records kept in the hospital. A total of 239 pSS patients (160 with labial salivary gland biopsy, and 79 without biopsy) and 52 age-matched non-pSS patients [(55.17±14.295),and (55.90±13.38) years old, P>0.05] (9 with biopsy, and 43 without biopsy) were involved in this study. The sensitivity and specificity of ACR criteria in diagnosing pSS were 90.37 % and 88.46 % respectively. The positive and negative likelihood ratios were 7.83 and 0.109, respectively. The sensitivities of ACR criteria in diagnosing pSS patients with and without labial biopsy were 88.75% and 93.67 %, respectively, with specificities of 88.89% and 88.37%, respectively. The most sensitive item adopted in ACR criteria was the ocular staining score with a sensitivity of 85.77%, and the most specific item was the labial salivary gland biopsy, with a specificity of 88.89%. The sensitivity and specificity of ACR criteria in diagnosing Chinese pSS patients were relatively high, and may serve as the diagnosis criteria in research and clinical practice. However, the ACR criteria need to be validated and further revised in the future .

Organ donation and transplant systems have unique characteristics based on the local culture and socioeconomic context. China's transplant and organ donation systems developed without regulatory oversight until 2006 when regulation and policy were developed and then implemented over the next several years. Most recently, the pilot project of establishing a voluntary citizen-based deceased donor program was established. The pilot program addressed the legal, financial, and cultural barriers to organ donation in China. The pilot program has evolved into a national program. Significantly, it established a uniquely Chinese donor classification system. The Chinese donor classification system recognizes donation after brain death (category I), donation after circulatory death (category II), and donation after brain death followed by circulatory death (category III). Through August 2014, the system has identified 2326 donors and provided 6416 organs that have been allocated though a transparent organ allocation system. The estimated number of donors in 2014 is 1147. As China's attitudes toward organ donation have matured and evolved and as China, as a nation, is taking its place on the world stage, it is recognizing that its past practice of using organs from executed prisoners is not sustainable. It is time to recognize that the efforts to regulate transplantation and provide voluntary citizen-based deceased organ donation have been successful and that China should use this system to provide organs for all transplants in every province and hospital in China. At the national organ transplant congress on October 30, 2014, the Chairman of the China's national organ donation and transplantation committee, Jeifu Huang required all hospitals to stop using organs from executed prisoners immediately and the civilian organ donation will be sole source for organ transplant in China starting January 2015. © 2015 American Association for the Study of Liver Diseases.

Hepatocellular carcinoma (HCC) is an important cancer in Malaysia. This study aimed to determine the epidemiological characteristics and clinical presentations of patients in a multiracial population consisting of three major Asian races: Malays, Chinese and Indians. Consecutive patients with HCC were prospectively studied from 2006 to 2009. HCC was diagnosed principally on multiphasic computed tomography and magnetic resonance imaging scans of the liver. The tumor was staged according to the Barcelona Clinic Liver Cancer (BCLC) classification. Altogether, 348 patients were diagnosed with HCC. There were 239 (68.7%) Chinese patients, 71 (20.4%) Malays and 38 (10.9%) Indians, with the median age of 62.5 years and the male to female ratio of 3.4:1. The predominant etiology in Malay and Chinese patients was hepatitis B virus infection (>60%) and in Indian patients was alcohol intake (26.3%) and cryptogenic cause (29.0%). Hepatitis C was seen in 18.3% of Malays, but less than 10% in Chinese and Indians. BCLC staging was: Stage A, 120 (34.5%); Stage B, 75 (21.6%); Stage C, 84 (24.1%); and Stage D, 69 (19.8%). A larger proportion of Indian than Chinese and Malays patients (44.7%) presented with stage D disease. Portal vein invasion was noted in 124 patients (35.6%) and extrahepatic metastases in 68 (19.5%). Surgical resection and radiofrequency ablation with curative intent was carried out in >90% of stage A patients and transarterial chemoembolization in 49.3% and 21.4% of stages B and C patients, respectively. HCC is most common among Chinese, followed by Malays and Indians in Malaysia. The etiology of HCC shows a peculiar racial pattern. © 2014 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Atractylodes is an East-Asiatic endemic genera that distributed in China, Japan and Russian Far Eastern. As an important resource of medicinal plant, atractylodes has long been used as herbal medicine. To example the significant features in its trueborn quality and geographical distribution, we explored the relationships between medicine quality and habitat suitability in two classifications-lower atractylodin content than the standard of Chinese Pharmacopoeia (2010) and the other has higher content. We found that the atractylodin content is negatively related to the habitat suitability for atractylodes with lower atractylodin, while the atractylodin content is positively related to the habitat suitability for those with higher atractylodin. By analyzing the distribution of atractylodeswith lower atractylodin content than the standard of Pharmacopeia, we discovered that the main ecological factors that could inhibit the accumulation of atractylodin were soil type (39.7%), soil clay content (26.7%), mean temperature in December (22.3%), Cation-exchange capacity (6%), etc. And these ecological factors promoted the accumulation of atractylodin for the atractylodes with higher atractylodin. By integrating the two classifications, we finally predicted the distribution of atractylodin content in China.Our results realized the query of atractylodes quality in arbitrary coordinates, and satisfied the actually cultivation demands of “Planting area based on atractylodin quality”.

Latitudinal variation in nematode diversity and ecological roles along the Chinese coast.

To test changes in the phylogenetic relatedness, niche breadth, and life-history strategies of nematodes along a latitudinal gradient. Sixteen wetland locations along the Pacific coast of China, from 20°N to 40°N. Linear regression was used to relate nematode phylogenetic relatedness (average taxonomic distinctness (AvTD) and average phylogenetic diversity [AvPD]), life-history group (based on " c - p " colonizer-persister group classification), and dietary specificity (based on guild classification of feeding selectivity) to latitude. Wetland nematode taxonomic diversity (richness and Shannon diversity indices) decreased with increasing latitude along the Chinese coast. Phylogenetic diversity indices (AvTD and AvPD) significantly increased with increasing latitude. This indicates that at lower latitudes, species within the nematode community were more closely related. With increasing latitude, the nematode relative richness and abundance decreased for selective deposit feeders but increased for nonselective deposit feeders. The proportion of general opportunists decreased with increasing latitude, but persisters showed the opposite trend. The annual temperature range and the pH of sediments were more important than vegetation type in structuring nematode communities. Nematode niche breadth was narrower at lower latitudes with respect to dietary specificity. Higher latitudes with a more variable climate favor r over K life-history strategists. Nematode communities at lower latitudes contained more closely related species.

Sparking Thinking: Studying Modern Precision Medicine Will Accelerate the Progression of Traditional Chinese Medicine Patterns.

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.

The organization of scientists and its relation to scientific productivity: Perceptions of Chinese stem cell researchers

PubMed Central

Zhang, Joy Yueyue

2013-01-01

Chinese government funding of R&D ranks third in the world. Yet China ranks only 17th in terms of scientific productivity per unit of investment. The author recently conducted fieldwork on the team structure of 22 Chinese stem cell research groups. Interview data suggest that although Chinese research groups closely resemble their international counter-parts in many respects, there are also significant differences which are perceived by interviewees to affect levels of scientific productivity. One characteristic of Chinese research teams is a common deficiency in middle-layer positions. This shortage of experienced professionals is perceived by scientists participating in this study to have led to two consequences. First, inexperienced student researchers often form the backbone of scientific teams in China, which leads to frequent interruptions of research and extended laboratory training. Second, research teams consist of a relatively small number of personnel. These structural features are seen to create excessive social boundaries, which impede the exchange of information and further worsens the segmentation of resources. This article engages the question of the extent to which interviewees’ local ‘embedded’ understandings of these difficulties may make a productive contribution to the analysis of the structural, and infra-structural, organization of Chinese professional bioscience teams.

The Leicester Cough Questionnaire (LCQ) has been validated for assessing cough-specific health status in bronchiectasis. We translated the LCQ into Mandarin Chinese and investigated its validity, reliability and responsiveness. The LCQ was translated into Mandarin Chinese using the forward-backward translation procedure. A total of 144 out-patients completed the Mandarin Chinese version of the LCQ (LCQ-MC), the Hospital Anxiety and Depression Scale (HADS) and the St George's Respiratory Questionnaire. Reassessments were performed during exacerbations and at 6 months. Concurrent validation, internal consistency, repeatability and responsiveness were determined. Minor cultural adaptations were made to the wording of LCQ-MC. No other difficulties were found during the translation process, with all items easily adapted to acceptable Mandarin Chinese. The questionnaire was not changed in terms of content layout and the order of the questions. In cognitive debriefing interviews, participants reported that the questionnaire was acceptable, relevant, comprehensive and easy to complete. The LCQ-MC showed good concurrent validity, internal consistency and test-retest reliability. Responsiveness was shown by significant changes in LCQ-MC scores between steady state, the first exacerbation and following 2-week antibiotic treatment (both interval changes, P < 0.01) CONCLUSION: The LCQ-MC is a valid, reliable and responsive instrument for determining cough-specific health status in Chinese bronchiectasis patients.

Nursing students' opinions about acupuncture and Chinese medicine.

Weber, J P

1975-01-01

Eighty senior nursing students at the University of San Francisco (USF) were divided at random into four groups of 20. Two groups were pretested on their knowledge of acupuncture and Chinese medicine. One week later a 50-minute class in acupuncture and Chinese medicine was given in a community health class to one of the two pretexted groups and one of the two untested groups. Following the class, the test was given to all four groups. Using the Solomon Four-Group design to measure effects of pretesting and the class content, significant differences were found between the groups on questions seeking differences, to confirm the first hypothesis that an increase in knowledge about acupuncture and Chinese medicine will accompany an increase in its acceptance as a healing tool and the desire to learn more about it. A t-test on the results of pre- and post- tests confirmed the second hypothesis that there will be no difference between groups in history or maturation from one week to the next.

Increasingly positive attitudes have been reported among young people in China towards mental illness, but little is known about Chinese medical students' attitudes towards psychiatry, psychiatric services and patients. We administered a bilingual survey to Wuhan University medical students in the final years of their clinical training. Primary outcomes were composite scores on a 21-item attitudes toward psychiatry (ATP) survey and the number of correct responses to diagnostic questions following a series of three clinical case vignettes. Mean composite score on the ATP items was 78/105 (SD = 9.6), representing overall positive attitudes among the students. Female gender and having learned about more psychiatric disorders were positively associated with a higher mean ATP score and remained so after adjustment for relevant covariates. Chinese medical students reported positive attitudes towards psychiatry, openness with regard to psychiatric services, and respect for psychiatric patients. Learning about a broad spectrum of psychiatric diagnoses and greater clinical contact with patients may improve overall attitudes of Chinese medical students towards psychiatry and their ability to make accurate diagnoses.

Culture and spontaneous self-concept among Filipino college students.

Watkins, D; Gerong, A

1997-08-01

Responses of 157 Filipino college students to the Twenty Statements Test (TST) were analyzed for content and compared with earlier responses to the TST by U.S. and Hong Kong Chinese college students. Despite the supposedly collectivist nature of the Filipino culture, far fewer Filipino students than U.S. and Hong Kong Chinese students described themselves in terms of social roles. Contrary to theoretical claims, the Filipinos made greater use of the global identity category than did either the U.S. or Hong Kong Chinese students. Evidence also supported the cross-cultural validity of 4 of the Big Five (McCrae & Costa, 1988) personality traits. However, there are questions about the relevance of Openness to Experience to any of these three cultures. Moreover, the finding that the Filipino respondents reported a higher percentage of positive self-descriptions than did either the U.S. or Chinese respondents indicated that such differences cannot be explained in terms of the individualism-collectivism dimension.

2009-01-01

Cultural influences on anatomy teaching and learning have been investigated by application of a questionnaire to medical students in British and Chinese Medical Schools. Results from the responses from students of the two countries were analyzed. Both groups found it easier to understand anatomy in a clinical context, and in both countries, student learning was driven by assessment. Curriculum design differences may have contributed to the British view wherein students were less likely to feel time pressure and enjoyed studying anatomy more than their Chinese counterparts. Different teaching approaches resulted in British students being more likely to recite definitions to learn, and the Chinese students found learning from cross-sectional images easy. Cultural differences may account for the observation that British students were more inclined to ask questions in class, and the preference of Chinese students to study in small groups. The findings give evidence to show how 'cultures of learning' influence students' approaches and indicate the importance of cultural influences as factors amongst international and home learner groups.

Dong, Jun; Tong, Jia-Fei; Liu, Xia

As cardiovascular diseases appear frequently in modern society, the medicine and health system should be adjusted to meet the new requirements. Chinese government has planned to establish basic community medical insurance system (BCMIS) before 2020, where remote medical service is one of core issues. Therefore, we have developed the "remote network hospital system" which includes data server and diagnosis terminal by the aid of wireless detector to sample ECG. To improve the efficiency of ECG processing, in this paper, abnormal vs. normal ECG classification approach based on key features and statistical learning is presented, and the results are analyzed. Large amount of normal ECG could be filtered by computer automatically and abnormal ECG is left to be diagnosed specially by physicians.

2017-01-01

Fast and accurate grading of Chinese Cantonese sausage is an important concern for customers, organizations, and the industry. Hyperspectral imaging in the spectral range of 874–1734 nm, combined with chemometric methods, was applied to grade Chinese Cantonese sausage. Three grades of intact and sliced Cantonese sausages were studied, including the top, first, and second grades. Support vector machine (SVM) and random forests (RF) techniques were used to build two different models. Second derivative spectra and RF were applied to select optimal wavelengths. The optimal wavelengths were the same for intact and sliced sausages when selected from second derivative spectra, while the optimal wavelengths for intact and sliced sausages selected using RF were quite similar. The SVM and RF models, using full spectra and the optimal wavelengths, obtained acceptable results for intact and sliced sausages. Both models for intact sausages performed better than those for sliced sausages, with a classification accuracy of the calibration and prediction set of over 90%. The overall results indicated that hyperspectral imaging combined with chemometric methods could be used to grade Chinese Cantonese sausages, with intact sausages being better suited for grading. This study will help to develop fast and accurate online grading of Cantonese sausages, as well as other sausages. PMID:28757578

The objective of this paper was to investigate the sequence types (STs) and diversity of surface antigen pneumococcal surface protein A (PspA) in 171 invasive Streptococcus pneumoniae isolates from Chinese children. A total of 171 pneumococci isolates were isolated from Chinese children with invasive pneumococcal diseases (IPD) in 11 hospitals between 2006 and 2008. The pneumococci samples were characterized by serotyping, PspA classification, and multilocus sequence typing (MLST). The PspA of these strains could be assigned to two families. The PspA family 2 was the most common (120/171, 70.1%). No PspA family 3 isolates were detected. Family 1 could be subdivided into two clades, with 42 strains in clade 1 and 9 strains in clade 2, and family 2 could be subdivided into clades 3, 4, and 5, which respectively contained 5, 21, and 14 strains. In total, 65 STs were identified, of which ST320 (30/171, 17.5%), ST271 (23/171, 13.5%), and ST876 (18/171, 10.5%) were the most common types. PspA family 2 and family 1 were dominant among pneumococcal clones isolated from Chinese children with invasive disease. The strains with the same ST always presented in the same PspA family.

The purpose of the present study was to estimate the prevalence of depression in Chinese university students, and to identify the socio-demographic factors associated with depression in this population. A multi-stage stratified sampling procedure was used to select university students (N = 5245) in Harbin (Heilongjiang Province, Northeastern China), who were aged 16–35 years. The Beck Depression Inventory (BDI) was used to determine depressive symptoms of the participants. BDI scores of 14 or higher were categorized as depressive for logistic regression analysis. Depression was diagnosed by the Structured Clinical Interview (SCID) for the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition (DSM-IV). 11.7% of the participants had a BDI score 14 or higher. Major Depressive Disorder was seen in 4.0% of Chinese university students. There were no statistical differences in the incidence of depression when gender, ethnicity, and university classification were analyzed. Multivariate analysis showed that age, study year, satisfaction with major, family income situation, parental relationship and mother's education were significantly associated with depression. Moderate depression is prevalent in Chinese university students. The students who were older, dissatisfied with their major, had a lower family income, poor parental relationships, and a lower level of mother's education were susceptible to depression.

AIM—To estimate the rates of hospital admissions for primary angle closure glaucoma (PACG) in Chinese, Malays, and Indians in Singapore
METHODS—A population-wide hospital discharge database in Singapore was used to identify all hospital admissions with a primary discharge diagnosis of PACG (International Classification of Disease—CM code: 365.2). The Singapore census was used for denominator data.
RESULTS—Between 1993 and 1997 there were 894 hospital admissions for PACG. The mean annual rate of PACG admissions was 11.1 per 100 000 (95% confidence interval (CI), 10.4, 11.8) among people aged 30 years and over. The annual rate was highest for Chinese (age and sex adjusted rate: 12.2 per 100 000), which was twice that of Malays (6.0 per 100 000) and Indians (6.3 per 100 000). Females had two times higher rates than males in all three races (age adjusted relative risk: 2.0, 95% CI: 1.7, 2.3).
CONCLUSION—Malay and Indian people had identical rates of hospital admissions for PACG, which were only half the rates compared with Chinese.

This is the first study aimed to determine the morbidity pattern in different Traditional Chinese Medicine (TCM) primary care settings in Chinese population. 55,312 patients' encounters were classified by the International Classification of Primary Care-2 (ICPC-2) from 260 of CMPs. Mean patient age was 50.5 years, with more females than males (67.0% vs 33.0%). Most patients consulted CMPs for chronic (64% vs 33.7%) rather than acute conditions. Among the 30% of patients, hypertension (49.5%) or diabetes (18.5%) were the most common co-morbidity. The most common problems presenting to CMP were respiratory (24.9%), musculoskeletal complaints (22.7%), cough (11.7%), and lower back pain (6.6%). To our knowledge, this was the first study permitting direct comparison with that presenting to Western medicine (WM) primary care by ICPC-2 systems. The results confirmed the role of CMP in primary care for musculoskeletal or chronic illnesses that they may have also received conventional WM treatment. We recommend greater effort and more resources should be invested to promote interdisciplinary communication to ensure safety and synergy of TCM and WM in primary care.

Identification accuracy of traditional Chinese medicine is crucial for the traditional Chinese medicine research, production and application. DNA barcoding based on the mitochondrial gene coding for cytochrome c oxidase subunit I (COI), are more and more used for identification of traditional Chinese medicine. Using universal barcoding primers to sequence, we discussed the feasibility of DNA barcoding method for identification commonly-used medicinal snakes (a total of 109 samples belonging to 19 species 15 genera 6 families). The phylogenetic trees using Neighbor-joining were constructed. The results indicated that the mean content of G + C(46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the mean intraspecies genetic distance of Trimeresurus albolabris, Ptyas dhumnades and Lycodon rufozonatus was greater than 2%. Further phylogenetic relationship results suggested that identification of one sample of T. albolabris was erroneous. The identification of some samples of P. dhumnades was also not correct, namely originally P. korros was identified as P. dhumnades. Factors influence on intraspecific genetic distance difference of L. rufozonatus need to be studied further. Therefore, DNA barcoding for identification of medicinal snakes is feasible, and greatly complements the morphological classification method. It is necessary to further study in identification of traditional Chinese medicine.

Discrimination of Chinese rice wines from three well-known wineries ("Guyuelongshan", "Kuaijishan", and "Pagoda") in China has been carried out according to mineral element contents in this study. Nineteen macro and trace mineral elements (Na, Mg, Al, K, Ca, Mn, Fe, Cu, Zn, V, Cr, Co, Ni, As, Se, Mo, Cd, Ba and Pb) were determined by inductively coupled plasma mass spectrometry (ICP-MS) in 117 samples. Then the experimental data were subjected to analysis of variance (ANOVA) and principal component analysis (PCA) to reveal significant differences and potential patterns between samples. Stepwise linear discriminant analysis (LDA) and partial least square discriminant analysis (PLS-DA) were applied to develop classification models and achieved correct classified rates of 100% and 97.4% for the prediction sample set, respectively. The discrimination could be attributed to different raw materials (mainly water) and elaboration processes employed. The results indicate that the element compositions combined with multivariate analysis can be used as fingerprinting techniques to protect prestigious wineries and enable the authenticity of Chinese rice wine.

Rapid discrimination of pork in Halal and non-Halal Chinese ham sausages was developed by Fourier transform infrared (FTIR) spectrometry combined with chemometrics. Transmittance spectra ranging from 400 to 4000 cm⁻¹ of 73 Halal and 78 non-Halal Chinese ham sausages were measured. Sample preparation involved finely grinding of samples and formation of KBr disks (under 10 MPa for 5 min). The influence of data preprocessing methods including smoothing, taking derivatives and standard normal variate (SNV) on partial least squares discriminant analysis (PLSDA) and least squares support vector machine (LS-SVM) was investigated. The results indicate removal of spectral background and baseline plays an important role in discrimination. Taking derivatives, SNV can improve classification accuracy and reduce the complexity of PLSDA. Possibly due to the loss of detailed high-frequency spectral information, smoothing degrades the model performance. For the best models, the sensitivity and specificity was 0.913 and 0.929 for PLSDA with SNV spectra, 0.957 and 0.929 for LS-SVM with second derivative spectra, respectively.

Smoking has a negative effect on most diseases, yet it is under-investigated in people with epilepsy; thus its role is not clear in the general population with epilepsy. We performed a retrospective pilot study on males with epilepsy to determine the smoking rate and its relationship with seizure control using univariate analysis to calculate odds ratios (ORs) and also used a multi-variate logistic regression model. The smoking rate in our sample of 278 individuals was 25.5%, which is lower than the general Chinese population smoking rate among males of 52.1%. We used two classifications: the first classified epilepsy as generalized, or by presumed topographic origin (temporal, frontal, parietal and occipital). The second classified the dominant seizure type of an individual as generalized tonic clonic seizure (GTCS), myoclonic seizure (MS), complex partial seizure (CPS), simple partial seizure (SPS), and secondary GTCS (sGTCS). The univariable analysis of satisfactory seizure control profile and smoking rate in both classifications showed a trend towards a beneficial effect of smoking although most were not statistically significant. Considering medication is an important confounding factor that would largely influence seizure control, we also conducted multi-variable analysis for both classifications with drug numbers and dosage. The result of our model also suggested that smoking is a protective factor. Our findings seem to suggest that smoking could have a potential role in seizure control although confounders need exploration particularly in view of the potential long term health effects. Replication in a much larger sample is needed as well as case control studies to elucidate this issue. Copyright © 2017 Elsevier Inc. All rights reserved.

We present a morphological catalogue for ˜670 000 galaxies in the Sloan Digital Sky Survey in two flavours: T-type, related to the Hubble sequence, and Galaxy Zoo 2 (GZ2 hereafter) classification scheme. By combining accurate existing visual classification catalogues with machine learning, we provide the largest and most accurate morphological catalogue up to date. The classifications are obtained with Deep Learning algorithms using Convolutional Neural Networks (CNNs). We use two visual classification catalogues, GZ2 and Nair & Abraham (2010), for training CNNs with colour images in order to obtain T-types and a series of GZ2 type questions (disc/features, edge-on galaxies, bar signature, bulge prominence, roundness, and mergers). We also provide an additional probability enabling a separation between pure elliptical (E) from S0, where the T-type model is not so efficient. For the T-type, our results show smaller offset and scatter than previous models trained with support vector machines. For the GZ2 type questions, our models have large accuracy (>97 per cent), precision and recall values (>90 per cent), when applied to a test sample with the same characteristics as the one used for training. The catalogue is publicly released with the paper.

When East meets West: intensive care unit experiences among first-generation Chinese American parents.

2009-01-01

To explore the experiences of first-generation Chinese American parents while their infants are cared for in intensive care units (ICUs). Because the study focus was on understanding the experiences of parents, a phenomenological approach was used, with open-ended questions that encouraged participants to describe events they perceived to be important. The data analysis procedure suggested by van Manen was used for the qualitative data analysis. A convenience sample of 25 first-generation Chinese American families, with infants hospitalized in the intensive care units of three teaching hospitals in the San Francisco area. Seven themes were identified: perceived incompetence, self-blame, blame from others, filial piety, lack of support in the US, communication issues, and cultural differences. Both fathers and mothers experienced stress related to all identified themes. Findings suggest the need for more resources to educate and support families as well as culturally competent care within pediatric ICUs. Further study is critical to understand how the Chinese American's personal and family characteristics may influence stress perceptions when coping with their children's hospitalization. This study can help healthcare providers to understand Chinese American parents' perceptions while their infants are hospitalized in the ICU, which can enhance cultural competence care services.

Gender atypical behavior in Chinese school-aged children: its prevalence and relation to sex, age, and only child status.

This study had three purposes: (a) to compare the prevalence of boys' and girls' gender-atypical behaviors (GABs) in a sample of Chinese school-aged children, (b) to examine the developmental pattern of GABs in Chinese boys and girls over the age range in question (6-12 years), and (c) to test the effects of being an only child on children's GAB expression. Parents of 486 boys and 417 girls completed a Child Play Behavior and Activity Questionnaire (CPBAQ) in regard to their own children, and a demographic information sheet. The frequency distribution for each gender-related behavior was calculated. The associations between sex, age, and only-child status, and CPBAQ scale scores were examined. Although most GABs (by their very nature) were exhibited infrequently in Chinese children, it was found that girls displayed GABs more frequently than boys did. The prevalence of GABs rose for girls as they grew older, but fell slightly for boys. The expressions of GABs in only children did not differ from that in children with siblings. Possible effects of Chinese culture (including the current only-child policy) on children's GABs are discussed.

The perception of FM sweeps by Chinese and English listeners.

Luo, Huan; Boemio, Anthony; Gordon, Michael; Poeppel, David

2007-02-01

Frequency-modulated (FM) signals are an integral acoustic component of ecologically natural sounds and are analyzed effectively in the auditory systems of humans and animals. Linearly frequency-modulated tone sweeps were used here to evaluate two questions. First, how rapid a sweep can listeners accurately perceive? Second, is there an effect of native language insofar as the language (phonology) is differentially associated with processing of FM signals? Speakers of English and Mandarin Chinese were tested to evaluate whether being a speaker of a tone language altered the perceptual identification of non-speech tone sweeps. In two psychophysical studies, we demonstrate that Chinese subjects perform better than English subjects in FM direction identification, but not in an FM discrimination task, in which English and Chinese speakers show similar detection thresholds of approximately 20 ms duration. We suggest that the better FM direction identification in Chinese subjects is related to their experience with FM direction analysis in the tone-language environment, even though supra-segmental tonal variation occurs over a longer time scale. Furthermore, the observed common discrimination temporal threshold across two language groups supports the conjecture that processing auditory signals at durations of approximately 20 ms constitutes a fundamental auditory perceptual threshold.

To investigate why first-generation Chinese immigrants with diabetes have difficulty obtaining, processing and understanding diabetes related information despite the existence of translated materials and translators. This qualitative study employed purposive sampling. Six focus groups and two individual interviews were conducted. Each group discussion lasted approximately 90 min and was guided by semistructured and open-ended questions. Data were collected in two community health centres and one elderly retirement village in Los Angeles, California. 29 Chinese immigrants aged ≥45 years and diagnosed with type 2 diabetes for at least 1 year. Eight key themes were found to potentially affect Chinese immigrants' capacity to obtain, communicate, process and understand diabetes related health information and consequently alter their decision making in self-care. Among the themes, three major categories emerged: cultural factors, structural barriers, and personal barriers. Findings highlight the importance of cultural sensitivity when working with first-generation Chinese immigrants with diabetes. Implications for health professionals, local community centres and other potential service providers are discussed. Published by the BMJ Publishing Group Limited.

Three Chinese patients with head and neck paragangliomas have been reported to carry the c.3G>C mutation in the succinate dehydrogenase subunit D (SDHD) gene. In addition, in our hospital, two further patients were identified who have the same mutation. It is unclear whether the c.3G>C mutation in Chinese patients is a recurrent mutation or if it is due to a founder effect. We conducted haplotype analysis on these patients to answer this question. Individual case-control study. Germ-line mutations were confirmed in the patients and their families examined in this study using direct sequencing. We also constructed and analyzed haplotypes in four Chinese families. Genotype frequencies were compared to the control group. Three of four families shared the same haplotype, which rarely occurred in the control group. The last family shared a very short area on the physical map with the other three families. There is a founder effect in Chinese head and neck paraganglioma patients carrying the SDHD c.3G>C mutation. Copyright © 2011 The American Laryngological, Rhinological, and Otological Society, Inc.

2005-06-01

The Hong Kong Chinese version of the WHOQOL-BREF was designed as a self-administered questionnaire and has limitations in clinical application on subjects who have limitations in reading or writing. An interview version is therefore needed to avoid sampling biases in clinical studies. Since there are significant differences in the written Chinese and spoken Cantonese, which is a dialect commonly spoken among people in Hong Kong, and adaptation process for converting the written Chinese into spoken Cantonese was necessary. The interview version was designed to allow administration in both face-to-face interview and telephone interview mode. Three members of the research team translated the formal written Chinese in the self-administered version of the WHOQOL-BREF(HK) into colloquial Cantonese separately. Brief notes extracted from the facet definitions of the WHOQOL-100 were added in brackets after some questions to further explain the intention of the questions. Two series of focus groups were conducted and subsequently the field test version was produced. 329 subjects were recruited by convenient sampling method for the field test. The interview version and the self-administered version was found equivalent. The ICC values of the domain scores ranged from 0.73 in the environment domain to 0.83 in the psychological domain. The face-to-face interview and telephone interview mode of administration were also found equivalent. The ICC for the domain scores ranged from 0.76 in the social interaction domain to 0.84 in the psychological domain. The other psychometric properties of the interview version were found comparable to the self-administered version. The self-administered and the interview version of the WHOQOL-BREF are regarded as identical in group comparison. The authors advise that it is acceptable to use different versions on different subjects in the same study, provided that the same version is applied on the same subject throughout the study.

Perceptions of unmet healthcare needs: what do Punjabi and Chinese-speaking immigrants think? A qualitative study.

Unmet healthcare needs - the difference between healthcare services deemed necessary to deal with a particular health problem and the actual services received - is commonly measured by the question, "During the past 12 months, was there ever a time when you felt that you needed healthcare, but you didn't receive it?" In 2003, unmet needs were reported by 10% of immigrants in Canada, yet, little is known specifically about Chinese- or Punjabi-speaking immigrants' perceptions and reporting of unmet needs. Our study examined: 1) How are unmet healthcare needs conceptualized among Chinese- and Punjabi-speaking immigrants? 2) Are their primary healthcare experiences related to their unmet healthcare needs? Twelve focus groups (6 Chinese, 6 Punjabi; n = 78) were conducted in Chinese or Punjabi and socio-demographic and health data were collected. Thematic analysis of focus group data examined the perceptions of unmet needs and any relationship to primary healthcare experiences. Our analysis revealed two overarching themes: 1) defining an unmet healthcare need and 2) identifying an unmet need. Participants had unmet healthcare needs in relation to barriers to accessing care, their lack of health system literacy, and when the health system was less responsive than their expectations. Asking whether someone ever had a time when they needed healthcare but did not receive it can either underestimate or overestimate unmet need. Measuring unmet need using single items is likely insufficient since more detail in a revised set of questions could begin to clarify whether the reporting of an unmet need was based on an expectation or a clinical need. Who defines what an unmet healthcare need is depends on the context (insured versus uninsured health services, experience in two or more healthcare systems versus experience in one healthcare system) and who is defining it (provider, patient, insurer).

Ontology-based systematic representation and analysis of traditional Chinese drugs against rheumatism.

Rheumatism represents any disease condition marked with inflammation and pain in the joints, muscles, or connective tissues. Many traditional Chinese drugs have been used for a long time to treat rheumatism. However, a comprehensive information source for these drugs is still missing, and their anti-rheumatism mechanisms remain unclear. An ontology for anti-rheumatism traditional Chinese drugs would strongly support the representation, analysis, and understanding of these drugs. In this study, we first systematically collected reported information about 26 traditional Chinese decoction pieces drugs, including their chemical ingredients and adverse events (AEs). By mostly reusing terms from existing ontologies (e.g., TCMDPO for traditional Chinese medicines, NCBITaxon for taxonomy, ChEBI for chemical elements, and OAE for adverse events) and making semantic axioms linking different entities, we developed the Ontology of Chinese Medicine for Rheumatism (OCMR) that includes over 3000 class terms. Our OCMR analysis found that these 26 traditional Chinese decoction pieces are made from anatomic entities (e.g., root and stem) from 3 Bilateria animals and 23 Mesangiospermae plants. Anti-inflammatory and antineoplastic roles are important for anti-rheumatism drugs. Using the total of 555 unique ChEBI chemical entities identified from these drugs, our ChEBI-based classification analysis identified 18 anti-inflammatory, 33 antineoplastic chemicals, and 9 chemicals (including 3 diterpenoids and 3 triterpenoids) having both anti-inflammatory and antineoplastic roles. Furthermore, our study detected 22 diterpenoids and 23 triterpenoids, including 16 pentacyclic triterpenoids that are likely bioactive against rheumatism. Six drugs were found to be associated with 184 unique AEs, including three AEs (i.e., dizziness, nausea and vomiting, and anorexia) each associated with 5 drugs. Several chemical entities are classified as neurotoxins (e.g., diethyl phthalate) and allergens (e.g., eugenol), which may explain the formation of some TCD AEs. The OCMR could be efficiently queried for useful information using SPARQL scripts. The OCMR ontology was developed to systematically represent 26 traditional anti-rheumatism Chinese drugs and their related information. The OCMR analysis identified possible anti-rheumatism and AE mechanisms of these drugs. Our novel ontology-based approach can also be applied to systematic representation and analysis of other traditional Chinese drugs.

Chloroplast DNA (cpDNA) is frequently used for species demography, evolution, and species discrimination of plants. However, the lack of efficient and universal markers often brings particular challenges for genetic studies across different plant groups. In this study, chloroplast genomes from two closely related species (Quercus rubra and Castanea mollissima) in Fagaceae were compared to explore universal cpDNA markers for the Chinese oak species in Quercus subgenus Quercus, a diverse species group without sufficient molecular differentiation. With the comparison, nine and 14 plastid markers were selected as barcoding and phylogeographic candidates for the Chinese oaks. Five (psbA-trnH, matK-trnK, ycf3-trnS, matK, and ycf1) of the nine plastid candidate barcodes, with the addition of newly designed ITS and a single-copy nuclear gene (SAP), were then tested on 35 Chinese oak species employing four different barcoding approaches (genetic distance-, BLAST-, character-, and tree-based methods). The four methods showed different species identification powers with character-based method performing the best. Of the seven barcodes tested, a barcoding gap was absent in all of them across the Chinese oaks, while ITS and psbA-trnH provided the highest species resolution (30.30%) with the character- and BLAST-based methods, respectively. The six-marker combination (psbA-trnH + matK-trnK + matK + ycf1 + ITS + SAP) showed the best species resolution (84.85%) using the character-based method for barcoding the Chinese oaks. The barcoding results provided additional implications for taxonomy of the Chinese oaks in subg. Quercus, basically identifying three major infrageneric clades of the Chinese oaks (corresponding to Groups Quercus, Cerris, and Ilex) referenced to previous phylogenetic classification of Quercus. While the morphology-based allocations proposed for the Chinese oaks in subg. Quercus were challenged. A low variation rate of the chloroplast genome, and complex speciation patterns involving incomplete lineage sorting, interspecific hybridization and introgression, possibly have negative impacts on the species assignment and phylogeny of oak species.

2015-01-01

Introduction. Suicide has become a serious worldwide epidemic. Early detection of individual suicide risk in population is important for reducing suicide rates. Traditional methods are ineffective in identifying suicide risk in time, suggesting a need for novel techniques. This paper proposes to detect suicide risk on social media using a Chinese suicide dictionary. Methods. To build the Chinese suicide dictionary, eight researchers were recruited to select initial words from 4,653 posts published on Sina Weibo (the largest social media service provider in China) and two Chinese sentiment dictionaries (HowNet and NTUSD). Then, another three researchers were recruited to filter out irrelevant words. Finally, remaining words were further expanded using a corpus-based method. After building the Chinese suicide dictionary, we tested its performance in identifying suicide risk on Weibo. First, we made a comparison of the performance in both detecting suicidal expression in Weibo posts and evaluating individual levels of suicide risk between the dictionary-based identifications and the expert ratings. Second, to differentiate between individuals with high and non-high scores on self-rating measure of suicide risk (Suicidal Possibility Scale, SPS), we built Support Vector Machines (SVM) models on the Chinese suicide dictionary and the Simplified Chinese Linguistic Inquiry and Word Count (SCLIWC) program, respectively. After that, we made a comparison of the classification performance between two types of SVM models. Results and Discussion. Dictionary-based identifications were significantly correlated with expert ratings in terms of both detecting suicidal expression (r = 0.507) and evaluating individual suicide risk (r = 0.455). For the differentiation between individuals with high and non-high scores on SPS, the Chinese suicide dictionary (t1: F 1 = 0.48; t2: F 1 = 0.56) produced a more accurate identification than SCLIWC (t1: F 1 = 0.41; t2: F 1 = 0.48) on different observation windows. Conclusions. This paper confirms that, using social media, it is possible to implement real-time monitoring individual suicide risk in population. Results of this study may be useful to improve Chinese suicide prevention programs and may be insightful for other countries.

Writing System Modulates the Association between Sensitivity to Acoustic Cues in Music and Reading Ability: Evidence from Chinese-English Bilingual Children.

PubMed

Zhang, Juan; Meng, Yaxuan; Wu, Chenggang; Zhou, Danny Q

2017-01-01

Music and language share many attributes and a large body of evidence shows that sensitivity to acoustic cues in music is positively related to language development and even subsequent reading acquisition. However, such association was mainly found in alphabetic languages. What remains unclear is whether sensitivity to acoustic cues in music is associated with reading in Chinese, a morphosyllabic language. The present study aimed to answer this question by measuring music (i.e., musical metric perception and pitch discrimination), language (i.e., phonological awareness, lexical tone sensitivity), and reading abilities (i.e., word recognition) among 54 third-grade Chinese-English bilingual children. After controlling for age and non-verbal intelligence, we found that both musical metric perception and pitch discrimination accounted for unique variance of Chinese phonological awareness while pitch discrimination rather than musical metric perception predicted Chinese lexical tone sensitivity. More importantly, neither musical metric perception nor pitch discrimination was associated with Chinese reading. As for English, musical metric perception and pitch discrimination were correlated with both English phonological awareness and English reading. Furthermore, sensitivity to acoustic cues in music was associated with English reading through the mediation of English phonological awareness. The current findings indicate that the association between sensitivity to acoustic cues in music and reading may be modulated by writing systems. In Chinese, the mapping between orthography and phonology is not as transparent as in alphabetic languages such as English. Thus, this opaque mapping may alter the auditory perceptual sensitivity in music to Chinese reading.

Obesity is a health problem in China, but there are no reports on the obesity status of Chinese citizens with intellectual disabilities (ID). Research has shown that adults with ID have higher body mass index (BMI) than adults without ID, but this information is primarily based on populations residing in North American and European countries. The purpose of this study was to compare BMI and obesity status of Chinese and U.S. Special Olympic athletes with ID. Height, weight, BMI and self-reported physical activity (SRPA) data from the Special Olympics 2006 U.S. National Games and 2007 Shanghai World Games databases were analyzed. Linear and logistic analyses were conducted for continuous data and dichotomous variables, respectively. Predictor variables were age, gender, country, SRPA, and obesity status according to country specific criteria. Significance was set at p < 0.05. The U.S. group had significantly higher BMI values than their Chinese counterparts. Age (p = 0.001) and country (p = <0.001) were the main predictors of BMI and obesity status, even when country-specific standards of obesity classifications were used. Holding all other factors constant, each unit increase of age was associated with increased odds for obesity by a factor of 1.04 and the odds of obesity occurring in U.S. athletes was 2.47 times greater than in Chinese athletes. Obesity is an emerging health problem for Chinese adults with ID. Participation in Special Olympics does not offset obesity in people with ID and other methods of intervention are needed to address obesity in this population segment. This is a global health concern that requires immediate attention. Copyright © 2015 Elsevier Ltd. All rights reserved.

To develop Singapore Chinese and English versions of the Psoriatic Arthritis Quality of Life (PsAQoL) scale that were equivalent to and met the same psychometric and acceptability standards as the original UK measure. Translation of the original PsAQoL into contextualised English and Chinese versions for use in Singapore was performed by professional and lay translation panels. Ten Chinese speaking and ten English speaking local patients were interviewed to assess face and content validity. Psoriatic arthritis (PsA) patients (either Chinese or English speaking) fulfilling the Classification criteria of Psoriatic Arthritis were then invited to participate in a validation survey. Clinical variables, the Health Assessment Questionnaire (HAQ) and the Medical Outcome Short-form 36 (SF-36) were used as comparator instruments for convergent validity. A separate sample of PsA patients were invited to participate in a test-retest postal study, with two weeks between administrations. The validation sample included 98 patients (51 % men) with a mean (SD) age of 51.5 (13.8) years. The PsAQoL had excellent internal consistency (Cronbach's α = 0.92) and scores on the measure were moderately correlated with health status measures (pain, HAQ score, SF-36 scores) and patient and physician global assessments. The scale was able to distinguish between groups with active or inactive disease assessed by composite scores, HAQ and minimal disease activity. Test-retest reliability was excellent (r = 0.92). This study provides evidence that the adapted English and Chinese versions of the PsAQoL can be used in clinical studies with PsA patients in Singapore.

In total, 246 individuals from 8 Chinese indigenous blue- and brown-shelled chicken populations (Yimeng Blue, Wulong Blue, Lindian Blue, Dongxiang Blue, Lushi Blue, Jingmen Blue, Dongxiang Brown, and Lushi Brown) were genotyped for 21 SNP markers from the SLCO1B3 gene to evaluate phylogenetic relationships. As a representative of nonblue-shelled breeds, White Leghorn was included in the study for reference. A high proportion of SNP polymorphism was observed in Chinese chicken populations, ranging from 89% in Jingmen Blue to 100% in most populations, with a mean of 95% across all populations. The White Leghorn breed showed the lowest polymorphism, accounting for 43% of total SNPs. The mean expected heterozygosity varied from 0.11 in Dongxiang Blue to 0.46 in Yimeng Blue. Analysis of molecular variation (AMOVA) for 2 groups of Chinese chickens based on eggshell color type revealed 52% within-group and 43% between-group variations of the total genetic variation. As expected, FST and Reynolds' genetic distance were greatest between White Leghorn and Chinese chicken populations, with average values of 0.40 and 0.55, respectively. The first and second principal coordinates explained approximately 92% of the total variation and supported the clustering of the populations according to their eggshell color type and historical origins. STRUCTURE analysis showed a considerable source of variation among populations for the clustering into blue-shelled and nonblue-shelled chicken populations. The low estimation of genetic differentiation (FST) between Chinese chicken populations is possibly due to a common historical origin and high gene flow. Remarkably similar population classifications were obtained with all methods used in the study. Aligning endogenous avian retroviral (EAV)-HP insertion sequences showed no difference among the blue-shelled chickens. © 2015 Poultry Science Association Inc.

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

The interaction of lexical tone, intonation and semantic context in on-line spoken word recognition: an ERP study on Cantonese Chinese.

2014-01-01

In two ERP experiments, we investigate the on-line interplay of lexical tone, intonation and semantic context during spoken word recognition in Cantonese Chinese. Experiment 1 shows that lexical tone and intonation interact immediately. Words with a low lexical tone at the end of questions (with a rising question intonation) lead to a processing conflict. This is reflected in a low accuracy in lexical identification and in a P600 effect compared to the same words at the end of a statement. Experiment 2 shows that a strongly biasing semantic context leads to much better lexical-identification performance for words with a low tone at the end of questions and to a disappearance of the P600 effect. These results support the claim that semantic context plays a major role in disentangling the tonal information from the intonational information, and thus, in resolving the on-line conflict between intonation and tone. However, the ERP data indicate that the introduction of a semantic context does not entirely eliminate on-line processing problems for words at the end of questions. This is revealed by the presence of an N400 effect for words with a low lexical tone and for words with a high-mid lexical tone at the end of questions. The ERP data thus show that, while semantic context helps in the eventual lexical identification, it makes the deviation of the contextually expected lexical tone from the actual acoustic signal more salient. © 2013 Published by Elsevier Ltd.

Discoveries are a driving force for progress in palaeontology. Palaeontology as a discipline of scientific inquiry has gained many fresh insights into the history of life, from the discoveries of many new fossils in China in the last 20 years, and from the new ideas derived from these fossils. This special issue of Proceedings of Royal Society B entitled Recent Advances in Chinese Palaeontology selects some of the very latest studies aimed at resolving the current problems of palaeontology and evolutionary biology based on new fossils from China. These fossils and their studies help to clarify some historical debates about a particular fossil group, or to raise new questions about history of life, or to pose a new challenge in our pursuit of science. These works on new Chinese fossils have covered the whole range of the diversity through the entire Phanerozoic fossil record.

Group Parent Training with Immigrant Chinese Families: Enhancing Engagement and Augmenting Skills Training

2013-01-01

Parent training (PT) is a well supported treatment for reducing and preventing child conduct problems and abusive parenting. However, questions have been raised about the dissemination of PT to culturally diverse families who hold different views on childrearing and family structure. This article describes the application of group PT in two Chinese immigrant families to illustrate dual strategies for addressing potential cultural barriers. The Incredible Years program builds in many therapeutic process elements to address cultural concerns about PT skills to enhance parental engagement. In addition, augmenting basic PT with additional skills training can help parents manage stressors common in immigrant families in order to facilitate uptake of new parenting skills. Our implementation experience suggests that high risk immigrant Chinese parents can be effectively engaged in group PT even when they are not in treatment voluntarily. PMID:20564684

2005-12-15

Chinese are the largest Asian group in the U.S., constituting 23.8% of the nation's total Asian-American population. Cancer is the leading cause of death for female Asian Americans, and breast cancer is the most frequently diagnosed cancer among females for all racial/ethic groups in San Francisco, which ranks 4th in the number of Asian Americans and where 152,620 Chinese account for 19.6% of the city's total population. Previous observations among Chinese immigrant women suggested that a diagnosis of breast cancer may be more detrimental to their well being compared with Chinese women who are born and raised in the U.S. This difference may be due to the lower socioeconomic status, limited English proficiency, poor understanding of the Western medical system among immigrants or other educational or financial considerations. In this qualitative pilot study, the authors sought to increase understanding of the relation between cultural beliefs and quality of life (QOL) among immigrant Chinese women with breast cancer in San Francisco. Specific objectives were 1) to identify these patients' beliefs regarding cancer, life expectancy, and discussion of advance directives; 2) to explore how these beliefs relate to patient QOL; and 3) to generate hypotheses for further study. The overall objective of the pilot study was to investigate questions central to the QOL issue, including what defines QOL for immigrant women and how QOL for them is similar to or different from that for American-born Chinese women.

This study investigated the knowledge of depression and preference for professional help, medications and treatment methods among Australians of Chinese-speaking background, and the perceptions of this population of the causes of mental illness. Adopting a cluster convenience sampling method, the study recruited 200 Chinese-speaking subjects from four major areas in metropolitan Melbourne where many Chinese live. The respondents were presented with a vignette describing an individual with depression and then asked questions to assess their understanding of depression and preference for professional help, medications and treatment methods. A comparative approach was used to compare the findings with those of a previous study of the mental health literacy of Australian and Japanese adults. Compared to the Australian and Japanese samples, a much lower percentage of Chinese-speaking Australians (14%) could correctly identify major depression described in the vignette, and a higher percentage believed that counseling professionals could be helpful. Higher percentages of those who believed that close family members could be helpful were found in the Chinese-speaking Australian and Japanese samples, and these two groups also expressed more uncertainty about the usefulness or harmfulness of certain medications compared to the Australian sample. Higher percentages of respondents in both the Chinese-speaking Australian and the Australian sample considered "lifestyle changes" to be helpful compared to the Japanese sample. In the Chinese-speaking sample, 30%, 17.4%, 33% and 27% of the respondents rated "traditional Chinese medicine doctors," "Chinese herbal medications," "taking Chinese nutritional foods/supplements" and "qiqong" as helpful. Many perceived "changing fungshui" and "traditional Chinese worship" to be harmful. Regarding the perception of causes of mental illness, items related to psychosocial perspectives including "life stress" and "interpersonal conflict" were rated highly by the respondents, whereas traditional beliefs including "punishment for misdeeds conducted by ancestors" and "demon possession" had the lowest ratings. Campaigns to increase the mental health literacy of Chinese-speaking Australians are needed. The above-mentioned socially and culturally driven beliefs need to be taken into consideration in the development of culturally relevant education programs.

2018-05-01

With the rapid development of Internet social media, excavating the emotional tendencies of the short text information from the Internet, the acquisition of useful information has attracted the attention of researchers. At present, the commonly used can be attributed to the rule-based classification and statistical machine learning classification methods. Although micro-blog sentiment analysis has made good progress, there still exist some shortcomings such as not highly accurate enough and strong dependence from sentiment classification effect. Aiming at the characteristics of Chinese short texts, such as less information, sparse features, and diverse expressions, this paper considers expanding the original text by mining related semantic information from the reviews, forwarding and other related information. First, this paper uses Word2vec to compute word similarity to extend the feature words. And then uses an ensemble classifier composed of SVM, KNN and HMM to analyze the emotion of the short text of micro-blog. The experimental results show that the proposed method can make good use of the comment forwarding information to extend the original features. Compared with the traditional method, the accuracy, recall and F1 value obtained by this method have been improved.

Tongue Images Classification Based on Constrained High Dispersal Network.

Computer aided tongue diagnosis has a great potential to play important roles in traditional Chinese medicine (TCM). However, the majority of the existing tongue image analyses and classification methods are based on the low-level features, which may not provide a holistic view of the tongue. Inspired by deep convolutional neural network (CNN), we propose a novel feature extraction framework called constrained high dispersal neural networks (CHDNet) to extract unbiased features and reduce human labor for tongue diagnosis in TCM. Previous CNN models have mostly focused on learning convolutional filters and adapting weights between them, but these models have two major issues: redundancy and insufficient capability in handling unbalanced sample distribution. We introduce high dispersal and local response normalization operation to address the issue of redundancy. We also add multiscale feature analysis to avoid the problem of sensitivity to deformation. Our proposed CHDNet learns high-level features and provides more classification information during training time, which may result in higher accuracy when predicting testing samples. We tested the proposed method on a set of 267 gastritis patients and a control group of 48 healthy volunteers. Test results show that CHDNet is a promising method in tongue image classification for the TCM study.

2007-12-01

Nowadays many Chinese companies have being becoming more and more international. Therefore, these Chinese companies have to face global supply chains rather than the former domestic ones. The use of information technology (IT) is considered a prerequisite for the effective control of today's complex global supply chains. Based on empirical data from 10 multinational companies of China, this paper presents a classification of the ways in which companies use IT in SCM, and examines the drivers for these different utilization types. According to the findings of this research, the purposes of using of IT in SCM can be divided into 1) transaction processing, 2) supply chain planning and collaboration, and 3) order tracking and delivery coordination. The findings further suggest that the drivers between these three uses of IT in SCM differ.

Land cover's refined classification based on multi source of remote sensing information fusion: a case study of national geographic conditions census in China

The project of The First National Geographic Conditions Census developed by Chinese government has designed the data acquisition content and indexes, and has built corresponding classification system mainly based on the natural property of material. However, the unified standard for land cover classification system has not been formed; the production always needs converting to meet the actual needs. Therefore, it proposed a refined classification method based on multi source of remote sensing information fusion. It takes the third-level classes of forest land and grassland for example, and has collected the thematic data of Vegetation Map of China (1:1,000,000), attempts to develop refined classification utilizing raster spatial analysis model. Study area is selected, and refined classification is achieved by using the proposed method. The results show that land cover within study area is divided principally among 20 classes, from subtropical broad-leaved forest (31131) to grass-forb community type of low coverage grassland (41192); what's more, after 30 years in the study area, climatic factors, developmental rhythm characteristics and vegetation ecological geographical characteristics have not changed fundamentally, only part of the original vegetation types have changed in spatial distribution range or land cover types. Research shows that refined classification for the third-level classes of forest land and grassland could make the results take on both the natural attributes of the original and plant community ecology characteristics, which could meet the needs of some industry application, and has certain practical significance for promoting the product of The First National Geographic Conditions Census.

Results of interobserver reliability studies for the International Urogynecological Association-International Continence Society (IUGA-ICS) Complication Classification coding can be greatly influenced by study design factors such as participant instruction, motivation, and test-question clarity. We attempted to optimize these factors. After a 15-min instructional lecture with eight clinical case examples (including images) and with classification/coding charts available, those clinicians attending an IUGA Surgical Complications workshop were presented with eight similar-style test cases over 10 min and asked to code them using the Category, Time and Site classification. Answers were compared to predetermined correct codes obtained by five instigators of the IUGA-ICS prostheses and grafts complications classification. Prelecture and postquiz participant confidence levels using a five-step Likert scale were assessed. Complete sets of answers to the questions (24 codings) were provided by 34 respondents, only three of whom reported prior use of the charts. Average score [n (%)] out of eight, as well as median score (range) for each coding category were: (i) Category: 7.3 (91 %); 7 (4-8); (ii) Time: 7.8 (98 %); 7 (6-8); (iii) Site: 7.2 (90 %); 7 (5-8). Overall, the equivalent calculations (out of 24) were 22.3 (93 %) and 22 (18-24). Mean prelecture confidence was 1.37 (out of 5), rising to 3.85 postquiz. Urogynecologists had the highest correlation with correct coding, followed closely by fellows and general gynecologists. Optimizing training and study design can lead to excellent results for interobserver reliability of the IUGA-ICS Complication Classification coding, with increased participant confidence in complication-coding ability.

A discussion is presented of machine learning theory on empirically learning classification rules. Six myths are proposed in the machine learning community that address issues of bias, learning as search, computational learning theory, Occam's razor, universal learning algorithms, and interactive learning. Some of the problems raised are also addressed from a Bayesian perspective. Questions are suggested that machine learning researchers should be addressing both theoretically and experimentally.

Identifying Chinese Microblog Users With High Suicide Probability Using Internet-Based Profile and Linguistic Features: Classification Model

2015-01-01

Background Traditional offline assessment of suicide probability is time consuming and difficult in convincing at-risk individuals to participate. Identifying individuals with high suicide probability through online social media has an advantage in its efficiency and potential to reach out to hidden individuals, yet little research has been focused on this specific field. Objective The objective of this study was to apply two classification models, Simple Logistic Regression (SLR) and Random Forest (RF), to examine the feasibility and effectiveness of identifying high suicide possibility microblog users in China through profile and linguistic features extracted from Internet-based data. Methods There were nine hundred and nine Chinese microblog users that completed an Internet survey, and those scoring one SD above the mean of the total Suicide Probability Scale (SPS) score, as well as one SD above the mean in each of the four subscale scores in the participant sample were labeled as high-risk individuals, respectively. Profile and linguistic features were fed into two machine learning algorithms (SLR and RF) to train the model that aims to identify high-risk individuals in general suicide probability and in its four dimensions. Models were trained and then tested by 5-fold cross validation; in which both training set and test set were generated under the stratified random sampling rule from the whole sample. There were three classic performance metrics (Precision, Recall, F1 measure) and a specifically defined metric “Screening Efficiency” that were adopted to evaluate model effectiveness. Results Classification performance was generally matched between SLR and RF. Given the best performance of the classification models, we were able to retrieve over 70% of the labeled high-risk individuals in overall suicide probability as well as in the four dimensions. Screening Efficiency of most models varied from 1/4 to 1/2. Precision of the models was generally below 30%. Conclusions Individuals in China with high suicide probability are recognizable by profile and text-based information from microblogs. Although there is still much space to improve the performance of classification models in the future, this study may shed light on preliminary screening of risky individuals via machine learning algorithms, which can work side-by-side with expert scrutiny to increase efficiency in large-scale-surveillance of suicide probability from online social media.

Chinese pregnant women attending their first antenatal visit or their first unbooked visit to the maternity ward were recruited during a 4-month study period in 2011. The participants completed self-administered questionnaires on demographic information, a single question on illicit drug use during pregnancy and the DAST-10. Urine samples screened positive by the urine Point-of-Care Test were confirmed by gas chromatography-mass spectrometry. DAST-10 performance was compared with three different gold standards: urinalysis, self-reported drug use, and evidence of drug use by urinalysis or self-report. 1214 Chinese pregnant women participated in the study and 1085 complete DAST-10 forms were collected. Women who had used illicit drugs had significantly different DAST-10 scores than those who had not. The sensitivity of DAST-10 for identify illicit drug use in pregnant women ranged from 79.2% to 33.3% and specificity ranged from 67.7% to 99.7% using cut-off scores from ≥ 1 to ≥ 3. The ~ 80% sensitivity of DAST-10 using a cut-off score of ≥ 1 should be sufficient for screening of illicit drug use in Chinese pregnant women, but validation tests for drug use are needed.

Rates of international migration are increasing, which raises the question of how migration might influence couple relationship standards and impact on the standards of migrants forming intercultural relationships. We compared relationship standards in n = 286 Chinese living in Hong Kong, China, with standards in n = 401 Chinese migrants to a Western country (Australia) by administering the Chinese-Western Intercultural Couple Standards Scale (CWICSS). We also compared these two groups to n = 312 Westerners living in Australia. We first tested the structural invariance of the CWICSS across the three samples with a multigroup confirmatory factor analysis. There was marginal but acceptable fit of a model of two positively correlated latent factors: Couple Bond (with four indicators, such as demonstration of love and caring) and Family Responsibility (also with four indicators, such as extended family relations and preserving face). Within the limitations of the study, results suggest migration is associated predominantly with differences in women's, but not men's, relationship standards. Migrant Chinese women show alignment of Couple Bond standards with Western standards, and divergence of Family Responsibility standards from Western standards. Discussion focused on how migration and intercultural relationship experiences might differentially influence various domains of relationship standards, gender differences in migration effects on standards, and the implications for working with culturally diverse couples. © 2017 Family Process Institute.

The purpose of this study was to compare the relative effectiveness of three recruitment modalities for enrolling Chinese-American and white family caregivers into research studies to evaluate intervention strategies. A total of 116 Chinese Americans and 134 whites were screened for eligibility to participate in one of two clinical intervention trials. Participants were recruited using: 1) media sources; 2) nonprofessional referral sources; or 3) professional referrals. Each participant was asked an open-ended question about how they became aware of the programs offered. A smaller proportion of Chinese Americans (39%) than whites (50%) who responded to recruiting strategies actually enrolled as subjects. There was a significant interaction between ethnicity and recruitment strategy. Chinese-American caregivers who were recruited by nonprofessional sources were less likely to enroll in the intervention studies than those who were recruited through media sources or professional referrals. Whites, on the other hand, were more likely to be recruited through nonprofessional sources than the other two. A consumer-oriented approach, which included direct face-to-face contact with key community leaders, generated the highest number of Chinese-American participants. Culture-specific factors such as trust-building with social service agencies, demonstrating genuine commitment to the well-being of the target community, and linguistic and ethnic matching between research staff and potential participants appear helpful to successful research recruitment in this rapidly increasing segment of dementia caregivers.

Texture Feature Extraction and Classification for Iris Diagnosis

Ma, Lin; Li, Naimin

Appling computer aided techniques in iris image processing, and combining occidental iridology with the traditional Chinese medicine is a challenging research area in digital image processing and artificial intelligence. This paper proposes an iridology model that consists the iris image pre-processing, texture feature analysis and disease classification. To the pre-processing, a 2-step iris localization approach is proposed; a 2-D Gabor filter based texture analysis and a texture fractal dimension estimation method are proposed for pathological feature extraction; and at last support vector machines are constructed to recognize 2 typical diseases such as the alimentary canal disease and the nerve system disease. Experimental results show that the proposed iridology diagnosis model is quite effective and promising for medical diagnosis and health surveillance for both hospital and public use.

Toward automated consumer question answering: automatically separating consumer questions from professional questions in the healthcare domain.

PubMed

2011-12-01

Both healthcare professionals and healthcare consumers have information needs that can be met through the use of computers, specifically via medical question answering systems. However, the information needs of both groups are different in terms of literacy levels and technical expertise, and an effective question answering system must be able to account for these differences if it is to formulate the most relevant responses for users from each group. In this paper, we propose that a first step toward answering the queries of different users is automatically classifying questions according to whether they were asked by healthcare professionals or consumers. We obtained two sets of consumer questions (~10,000 questions in total) from Yahoo answers. The professional questions consist of two question collections: 4654 point-of-care questions (denoted as PointCare) obtained from interviews of a group of family doctors following patient visits and 5378 questions from physician practices through professional online services (denoted as OnlinePractice). With more than 20,000 questions combined, we developed supervised machine-learning models for automatic classification between consumer questions and professional questions. To evaluate the robustness of our models, we tested the model that was trained on the Consumer-PointCare dataset on the Consumer-OnlinePractice dataset. We evaluated both linguistic features and statistical features and examined how the characteristics in two different types of professional questions (PointCare vs. OnlinePractice) may affect the classification performance. We explored information gain for feature reduction and the back-off linguistic category features. The 10-fold cross-validation results showed the best F1-measure of 0.936 and 0.946 on Consumer-PointCare and Consumer-OnlinePractice respectively, and the best F1-measure of 0.891 when testing the Consumer-PointCare model on the Consumer-OnlinePractice dataset. Healthcare consumer questions posted at Yahoo online communities can be reliably classified from professional questions posted by point-of-care clinicians and online physicians. The supervised machine-learning models are robust for this task. Our study will significantly benefit further development in automated consumer question answering. Copyright © 2011 Elsevier Inc.

The aim of the present study was to investigate the preference and willingness-to-pay (WTP) of older Chinese adults for community end-of-life care in a nursing home rather than a hospital. A total of 1540 older Chinese adults from 140 nursing homes were interviewed. Four hypothetical questions were asked to explore their preferences for end-of-life care. Using a discrete choice approach, specific questions explored acceptable trade-offs between three attributes: availability of doctors onsite, attitude of the care staff and additional cost of care per month. Approximately 35% of respondents preferred end-of-life care in the nursing home, whereas 23% of them would consider it in a better nursing home. A good attitude of staff was the most important attribute of the care site. Respondents were willing to pay an extra cost of US$5 (HK$39) per month for more coverage of doctor's time, and US$49 (HK$379) for a better attitude of staff in the nursing home. The marginal WTP for both more coverage of doctor's time and better attitude of staff amounted to US$54 (HK$418). Respondents on government subsidy valued the cost attribute more highly, as expected, validating the hypothesis that those respondents would be less willing to pay an additional cost for end-of-life care. Older Chinese adults living in nursing homes are willing to pay an additional fee for community end-of-life care services in nursing homes. Both the availability of the doctor and attitudes of nursing home staff are important, with the most important attribute being the staff attitudes.

The treatment of COPD has become increasingly effective. Measures that range from behavioral changes, reduction in exposure to risk factors, education about the disease and its course, rehabilitation, oxygen therapy, management of comorbidities, and surgical and pharmacological treatments to end-of-life care allow health professionals to provide a personalized and effective therapy. The pharmacological treatment of COPD is one of the cornerstones of COPD management, and there have been many advances in this area in recent years. Given the greater availability of drugs and therapeutic combinations, it has become increasingly challenging to know the indications for, limitations of, and potential risks and benefits of each treatment modality. In order to critically evaluate recent evidence and systematize the major questions regarding the pharmacological treatment of COPD, 24 specialists from all over Brazil gathered to develop the present recommendations. A visual guide was developed for the classification and treatment of COPD, both of which were adapted to fit the situation in Brazil. Ten questions were selected on the basis of their relevance in clinical practice. They address the classification, definitions, treatment, and evidence available for each drug or drug combination. Each question was answered by two specialists, and then the answers were consolidated in two phases: review and consensus by all participants. The questions answered are practical questions and help select from among the many options the best treatment for each patient and his/her peculiarities.

How did you guess? Or, what do multiple-choice questions measure?

PubMed

Cox, K R

1976-06-05

Multiple-choice questions classified as requiring problem-solving skills have been interpreted as measuring problem-solving skills within students, with the implicit hypothesis that questions needing an increasingly complex intellectual process should present increasing difficulty to the student. This hypothesis was tested in a 150-question paper taken by 721 students in seven Australian medical schools. No correlation was observed between difficulty and assigned process. Consequently, the question-answering process was explored with a group of final-year students. Anecdotal recall by students gave heavy weight to knowledge rather than problem solving in answering these questions. Assignment of the 150 questions to the classification by three teachers and six students showed their congruence to be a little above random probability.

Airborne color-infrared photography (CIR) (1:12,000 scale) was used to map localized occurrences of the widespread and aggressive Chinese tallow (Sapium sebiferum), an invasive species. Photography was collected during senescence when Chinese tallow's bright red leaves presented a high spectral contrast within the native bottomland hardwood and upland forests and marsh land-cover types. Mapped occurrences were conservative because not all senescing tallow leaves are bright red simultaneously. To simulate low spectral but high spatial resolution satellite/airborne image and digital video data, the CIR photography was transformed into raster images at spatial resolutions approximating 0.5 in and 1.0 m. The image data were then spectrally classified for the occurrence of bright red leaves associated with senescing Chinese tallow. Classification accuracies were greater than 95 percent at both spatial resolutions. There was no significant difference in either forest in the detection of tallow or inclusion of non-tallow trees associated with the two spatial resolutions. In marshes, slightly more tallow occurrences were mapped with the lower spatial resolution, but there were also more misclassifications of native land covers as tallow. Combining all land covers, there was no difference at detecting tallow occurrences (equal omission errors) between the two resolutions, but the higher spatial resolution was associated with less inclusion of non-tallow land covers as tallow (lower commission error). Overall, these results confirm that high spatial (???1 m) but low spectral resolution remote sensing data can be used for mapping Chinese tallow trees in dominant environments found in coastal and adjacent upland landscapes.

The universal use of Arabic numbers in mathematics raises a question whether these digits are processed the same way in people speaking various languages, such as Chinese and English, which reflect differences in Eastern and Western cultures. Using functional MRI, we demonstrated a differential cortical representation of numbers between native Chinese and English speakers. Contrasting to native English speakers, who largely employ a language process that relies on the left perisylvian cortices for mental calculation such as a simple addition task, native Chinese speakers, instead, engage a visuo-premotor association network for the same task. Whereas in both groups the inferior parietal cortex was activated by a task for numerical quantity comparison, functional MRI connectivity analyses revealed a functional distinction between Chinese and English groups among the brain networks involved in the task. Our results further indicate that the different biological encoding of numbers may be shaped by visual reading experience during language acquisition and other cultural factors such as mathematics learning strategies and education systems, which cannot be explained completely by the differences in languages per se.

To study the body dissatisfaction of Chinese undergraduates and its implications for eating disorders in Hong Kong. A large sample of 1,581 subjects completed a "Body Dissatisfaction Questionnaire" (BDQ) which included 25 items about various body parts and questions on body indices, body shape dissatisfaction, and dieting. Whereas male subjects wanted to be taller and stronger in their upper body, the majority of female subjects felt fat in their lower body and were cognitively inclined to weigh less even though they were not obese. They desired a slimming of the stomach, thighs, waist and hip, but not the breasts. Body dissatisfaction was substantially intensified in females who reported a history of dieting in the previous year. Factor analysis of the BDQ affirmed the gender specificity and multidimensionality of body dissatisfaction. The typically "Western" pattern of body dissatisfaction has overshadowed the traditional Chinese notions of female beauty based on the face and other nontruncal features. In the context of a rapidly urbanizing Chinese society, this will predispose more females to weight control behavior and eating disorders.

Frontotemporal dementia (FTD) has rarely been reported in Chinese populations. There are many potential reasons for this, including possible hesitancy on the part of patients or families to bring FTD-related symptoms to medical attention. Here, we present data on eight Chinese individuals, all of whom met criteria for the behavioral variant of FTD or the semantic variant of primary progressive aphasia. These patients presented for neurological evaluation at a relatively advanced stage. The mean MMSE score at initial presentation was 15. Behavioral symptoms were common and usually elicited during the medical history only after direct questioning. Delay in presentation was attributed to a variety of issues, including family disagreements about whether the symptoms represented a disease and lack of medical insurance. These cases illustrate that the symptoms of FTD in Chinese Americans are similar to those in Caucasians but various factors, some potentially culturally-relevant, may influence the likelihood and timing of clinical presentation for FTD, as well as other dementias. Additional study of FTD in diverse ethnic groups needs to address barriers to clinical presentation, including factors that may be culturally specific. PMID:23311888

Under the influence of traditional oriental culture, the lack of organ donation is especially serious in China and Japan. The aim of this study was to compare Chinese and Japanese college students' attitudes and analyze contributing factors toward deceased donation. An anonymous, self-administered questionnaire comprising 15 questions was distributed to approximately 400 college students at Liaoning University, China, and Kyushu University, Japan. Statistical analysis used SPSS software. Japanese students' attitude towards deceased organ donation was more favorable than that of Chinese students (43.6% versus 35.9%, P = .001). Several factors contributed to positive responses by students from both countries: family perspective on organ donation and transplantation; decision to donate to family members; prior blood donation; living liver or kidney donation; possibility of needing a transplant; and willingness to receive a deceased or a living donor organ. More efforts must emphasize awareness and up-to-date knowledge regarding organ donation among citizens and should be undertaken by the Chinese and Japanese governments. Copyright © 2013 Elsevier Inc.

Huang, Edgar

2015-01-01

In this case study, based on six criteria, four Chinese hospitals were chosen from a national sample to showcase, through content analysis and in-depth interviews, the best practices of serving patients online. The extensive findings have addressed the following three questions: what these hospitals have in common in their Web development, what problems and challenges they are facing, and how they have excelled in serving their patients online. The study concludes that, like larger hospitals, smaller hospitals can also excel in creating an outstanding Web site to serve their patients so long as they truly care about their patients, have a clear vision and strong expertise in IT development. The study also concludes that Chinese private hospitals can learn from these state-owned hospitals in establishing a good reputation through professional and responsible interaction with patients. The four hospitals studied may shed light on the Web development in many other Chinese hospitals that are going through the same healthcare new media adoption. The findings from this study can also help Chinese hospitals form their visions in serving patients online.

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.

The accurate estimate of grassland carbon (C) is affected by many factors at the large scale. Here, we used six methods (three spatial interpolation methods and three grassland classification methods) to estimate C storage of Chinese grasslands based on published data from 2004 to 2014, and assessed the uncertainty resulting from different integrative methods. The uncertainty (coefficient of variation, CV, %) of grassland C storage was approximately 4.8% for the six methods tested, which was mainly determined by soil C storage. C density and C storage to the soil layer depth of 100 cm were estimated to be 8.46 ± 0.41 kg C m(-2) and 30.98 ± 1.25 Pg C, respectively. Ecosystem C storage was composed of 0.23 ± 0.01 (0.7%) above-ground biomass, 1.38 ± 0.14 (4.5%) below-ground biomass, and 29.37 ± 1.2 (94.8%) Pg C in the 0-100 cm soil layer. Carbon storage calculated by the grassland classification methods (18 grassland types) was closer to the mean value than those calculated by the spatial interpolation methods. Differences in integrative methods may partially explain the high uncertainty in C storage estimates in different studies. This first evaluation demonstrates the importance of multi-methodological approaches to accurately estimate C storage in large-scale terrestrial ecosystems.

Purpose Asian Americans have consistently reported poorer communication with physicians compared with non-Hispanic Whites (NHW). This qualitative study sought to elucidate the similarities and differences in communication with physicians between Chinese and NHW breast cancer survivors. Methods Forty-four Chinese and 28 NHW women with early-stage breast cancer (stage 0-IIa) from the Greater Bay Area Cancer Registry participated in focus group discussions or individual interviews. We oversampled Chinese women because little is known about their cancer care experiences. In both interview formats, questions explored patients’ experiences and feelings when communicating with physicians about their diagnosis, treatment, and follow-up care. Results Physician empathy at the time of diagnosis was important to both ethnic groups; however, during treatment and follow-up care, physicians’ ability to treat cancer and alleviate physical symptoms was a higher priority. NHW and US-born Chinese survivors were more likely to assert their needs, whereas Chinese immigrants accepted physician advice even when it did not alleviate physical problems (e.g., pain). Patients viewed all physicians as the primary source for information about cancer care. Many Chinese immigrants sought additional information from primary care physicians and stressed optimal communication over language concordance. Conclusions Physician empathy and precise information were important for cancer patients. Cultural differences such as the Western emphasis on individual autonomy vs. Chinese emphasis on respect and hierarchy can be the basis for the varied approaches to physician communication we observed. Interventions based on cultural understanding can foster more effective communication between immigrant patients and physicians ultimately improving patient outcomes. PMID:23903797

Music genre classification is a challenging research concept, for which open questions remain regarding classification approach, music piece representation, distances between/within genres, and so on. In this paper an investigation on the classification of generated music pieces is performed, based on the idea that grouping close related known pieces in different sets -or clusters- and then generating in an automatic way a new song which is somehow "inspired" in each set, the new song would be more likely to be classified as belonging to the set which inspired it, based on the same distance used to separate the clusters. Different music pieces representations and distances among pieces are used; obtained results are promising, and indicate the appropriateness of the used approach even in a such a subjective area as music genre classification is.

2013-07-26

Many HEV and HEV-like sequences have been reported during the last years, including isolates which may represent a number of potential new genera, new genotypes or new subtypes within the family Hepeviridae. Using the most common classification system, difficulties in the establishment of subtypes have been reported. Moreover the relevance of subtype classification for epidemiology can be questioned. In this study we have performed phylogenetic analyses based on whole capsid gene and complete HEV genomic sequences in order to evaluate the current classification of HEV at genotype and subtype levels. The results of our analyses modify the current taxonomy of genotype 3 and refine the established system for typing of HEV. In addition we suggest a classification for hepeviruses recently isolated from bats, ferrets, rats and wild boar. Copyright © 2013 Elsevier B.V. All rights reserved.

This study examined a graduated severity level approach to food addiction classification against associations with World Health Organization obesity classifications (body mass index, kg/m 2 ) among 408 people with type 2 diabetes. A survey including the Yale Food Addiction Scale and several demographic questions demonstrated four distinct Yale Food Addiction Scale symptom severity groups (in line with Diagnostic and Statistical Manual of Mental Disorders (5th ed.) severity indicators): non-food addiction, mild food addiction, moderate food addiction and severe food addiction. Analysis of variance with post hoc tests demonstrated each severity classification group was significantly different in body mass index, with each grouping being associated with increased World Health Organization obesity classifications. These findings have implications for diagnosing food addiction and implementing treatment and prevention methodologies of obesity among people with type 2 diabetes.

In this study, the extended morphological attribute profiles (EAPs) and independent component analysis (ICA) were combined for feature extraction of high-resolution multispectral satellite remote sensing images and the regularized least squares (RLS) approach with the radial basis function (RBF) kernel was further applied for the classification. Based on the major two independent components, the geometrical features were extracted using the EAPs method. In this study, three morphological attributes were calculated and extracted for each independent component, including area, standard deviation, and moment of inertia. The extracted geometrical features classified results using RLS approach and the commonly used LIB-SVM library of support vector machines method. The Worldview-3 and Chinese GF-2 multispectral images were tested, and the results showed that the features extracted by EAPs and ICA can effectively improve the accuracy of the high-resolution multispectral image classification, 2% larger than EAPs and principal component analysis (PCA) method, and 6% larger than APs and original high-resolution multispectral data. Moreover, it is also suggested that both the GURLS and LIB-SVM libraries are well suited for the multispectral remote sensing image classification. The GURLS library is easy to be used with automatic parameter selection but its computation time may be larger than the LIB-SVM library. This study would be helpful for the classification application of high-resolution multispectral satellite remote sensing images.

Regional features play a great role in the analysis of the differentiations of Homo erectus and Homo sapiens. However, this poses the question how widespread and variable these features are. In order to examine this with regard to the features commonly seen in China their occurrence and variability were determined in Chinese as well as in African crania of archaic and late Pleistocene/Holocene modern Homo sapiens. Furthermore, some features known from Africa were examined with regard to their occurrence and variability in China. Although the variability might change due to new finds, the present results for some features point to larger morphological spectra in the African than in the Chinese archaic Homo sapiens. It is furthermore remarkable that the early modern Chinese in many features show deviations from the pattern of archaic Homo sapiens of this region and exhibit broader spectra similar to those seen in African archaic and early modern Homo sapiens.

The nested case-control study design (or the case-control in a cohort study) is described here as a new study design used in safe evaluation of post-marketing traditional Chinese medicine injection. In the nested case-control study, cases of a disease that occur in a defined cohort are identified and, for each, a specified number of matched controls is selected from among those in the cohort who have not developed the disease by the time of disease occurrence in the case. For many research questions, the nested case-control design potentially offers impressive reductions in costs and efforts of data collection and analysis compared with the full cohort approach, with relatively minor loss in statistical efficiency. The nested case-control design is particularly advantageous for studies in safe evaluation of post-marketing traditional Chinese medicine injection. Some examples of the application of nested case-control study were given.

A cross-language study of perception of lexical stress in English.

This study investigates the question of whether language background affects the perception of lexical stress in English. Thirty native English speakers and 30 native Chinese learners of English participated in a stressed-syllable identification task and a discrimination task involving three types of stimuli (real words/pseudowords/hums). The results show that both language groups were able to identify and discriminate stress patterns. Lexical and segmental information affected the English and Chinese speakers in varying degrees. English and Chinese speakers showed different response patterns to trochaic vs. iambic stress across the three types of stimuli. An acoustic analysis revealed that two language groups used different acoustic cues to process lexical stress. The findings suggest that the different degrees of lexical and segmental effects can be explained by language background, which in turn supports the hypothesis that language background affects the perception of lexical stress in English.

The World Health Organization has asserted the importance of enhancing participation of people with disabilities within the International Classification of Functioning, Disability and Health framework. Participation is regarded as a vital outcome in community-based rehabilitation. The actualization of the right to participate is limited by social stigma and discrimination. To date, there is no validated instrument for use in Chinese communities to measure participation restriction or self-perceived stigma. This study aimed to translate and validate the Participation Scale and the Explanatory Model Interview Catalogue (EMIC) Stigma Scale for use in Chinese communities with people with physical disabilities. The Chinese versions of the Participation Scale and the EMIC stigma scale were administered to 264 adults with physical disabilities. The two scales were examined separately. The reliability analysis was studied in conjunction with the construct validity. Reliability analysis was conducted to assess the internal consistency and item-total correlation. Exploratory factor analysis was conducted to investigate the latent patterns of relationships among variables. A Rasch model analysis was conducted to test the dimensionality, internal validity, item hierarchy, and scoring category structure of the two scales. Both the Participation Scale and the EMIC stigma scale were confirmed to have good internal consistency and high item-total correlation. Exploratory factor analysis revealed the factor structure of the two scales, which demonstrated the fitting of a pattern of variables within the studied construct. The Participation Scale was found to be multidimensional, whereas the EMIC stigma scale was confirmed to be unidimensional. The item hierarchies of the Participation Scale and the EMIC stigma scale were discussed and were regarded as compatible with the cultural characteristics of Chinese communities. The Chinese versions of the Participation Scale and the EMIC stigma scale were thoroughly tested in this study to demonstrate their robustness and feasibility in measuring the participation restriction and perceived stigma of people with physical disabilities in Chinese communities. This is crucial as it provides valid measurements to enable comprehensive understanding and assessment of the participation and stigma among people with physical disabilities in Chinese communities.

Leishmaniasis is a worldwide epidemic disease caused by the genus Leishmania, which is still endemic in the west and northwest areas of China. Some viewpoints of the traditional taxonomy of Chinese Leishmania have been challenged by recent phylogenetic researches based on different molecular markers. However, the taxonomic positions and phylogenetic relationships of Chinese Leishmania isolates remain controversial, which need for more data and further analysis. In this study, the heat shock protein 70 (HSP70) gene and cytochrome b (cyt b) gene were used for phylogenetic analysis of Chinese Leishmania isolates from patients, dogs, gerbils, and sand flies in different geographic origins. Besides, for the interesting Leishmania sp. in China, the ultrastructure of three Chinese Leishmania sp. strains (MHOM/CN/90/SC10H2, SD, GL) were observed by transmission electron microscopy. Bayesian trees from HSP70 and cyt b congruently indicated that the 14 Chinese Leishmania isolates belong to three Leishmania species including L. donovani complex, L. gerbilli, and L. (Sauroleishmania) sp. Their identity further confirmed that the undescribed Leishmania species causing visceral Leishmaniasis (VL) in China is closely related to L. tarentolae. The phylogenetic results from HSP70 also suggested the classification of subspecies within L. donovani complex: KXG-918, KXG-927, KXG-Liu, KXG-Xu, 9044, SC6, and KXG-65 belong to L. donovani; Cy, WenChuan, and 801 were proposed to be L. infantum. Through transmission electron microscopy, unexpectedly, the Golgi apparatus were not observed in SC10H2, SD, and GL, which was similar to previous reports of reptilian Leishmania. The statistical analysis of microtubule counts separated SC10H2, SD, and GL as one group from any other reference strain (L. donovani MHOM/IN/80/DD8; L. tropica MHOM/SU/74/K27; L. gerbilli MRHO/CN/60/GERBILLI). The ultrastructural characteristics of Leishmania sp. partly lend support to the phylogenetic inference that Chinese Leishmania sp. is in close relationship with reptilian Leishmania.

This paper is a discussion of machine learning theory on empirically learning classification rules. The paper proposes six myths in the machine learning community that address issues of bias, learning as search, computational learning theory, Occam's razor, 'universal' learning algorithms, and interactive learnings. Some of the problems raised are also addressed from a Bayesian perspective. The paper concludes by suggesting questions that machine learning researchers should be addressing both theoretically and experimentally.

Researchers undertaking long term, large-scale ecological analyses face significant challenges for data collection and processing. Crowdsourcing via citizen science can provide an efficient method for analyzing large data sets. However, many scientists have raised questions about the quality of data collected by citizen scientists. Here we use Floating-Forests (http://floatingforests.org), a citizen science platform for creating a global time series of giant kelp abundance, to show that ensemble classifications of satellite data can ensure data quality. Citizen scientists view satellite images of coastlines and classify kelp forests by tracing all visible patches of kelp. Each image is classified by fifteen citizen scientists before being retired. To validate citizen science results, all fifteen classifications are converted to a raster and overlaid on a calibration dataset generated from previous studies. Results show that ensemble classifications from citizen scientists are consistently accurate when compared to calibration data. Given that all source images were acquired by Landsat satellites, we expect this consistency to hold across all regions. At present, we have over 6000 web-based citizen scientists' classifications of almost 2.5 million images of kelp forests in California and Tasmania. These results are not only useful for remote sensing of kelp forests, but also for a wide array of applications that combine citizen science with remote sensing.

2018-05-21

This study endeavors to advance the current literature by examining the gender differences in the caregiving experiences and the stress-buffering role of positive aspects of caregiving (PAC) among Chinese spousal caregivers of frail elders in Hong Kong. Forty-nine husband caregivers and 121 wife caregivers of frail elders in Hong Kong (N = 170) responded to the Positive Aspects of Caregiving (PAC) scale, the Zarit Burden Interview (ZBI), the 21-item Depression, Anxiety, and Stress Scales (DASS-21), and demographic questions. These spousal caregivers were diverse in age, and their care receivers were diverse in terms of age and health condition. As predicted, there were significant gender differences in the moderating effects of PAC on the relationships of caregiving burden to depression, anxiety, and overall psychological distress. While PAC significantly buffered the effects of caregiving burden on depression, anxiety, and overall psychological distress for wife caregivers, the moderating effects of PAC were not significant for husband caregivers. Unexpectedly, wife caregivers reported lower PAC, higher caregiving burden, and higher psychological distress. As these findings suggest that PAC is lower but more beneficial for Chinese wife caregivers than Chinese husband caregivers, helping professionals are recommended to use strengths-based interventions that target PAC when working with Chinese wife caregivers.

[Systematization of diseases and lesions of the endometrium by etiological and pathogenetical mechanisms of development to choose an optimal treatment].

Current clinical gynecology considers pathological states of endometrium (PSE) as one of the most challenging issue of the day. Many questions of etiology, pathogenesis, diagnostics, and treatment of PSE are still under discussion. Nowadays there isn't a whole agreed classification of PSE. Morphological classification remains the most widely used one, but morphological changes occurring in the endometrium don't show a wide variety of disorders related to these pathological states. A new clinicopathogenetic classification of PSE was proposed, which is based on choosing the optimal treatment with functional state of the disease taken into account. This classification helps us to perceive the problem as a whole with choosing functionally based treatment for each patient.

The Paris classification is an international classification system for describing polyp morphology. Thus far, the validity and reproducibility of this classification have not been assessed. We aimed to determine the interobserver agreement for the Paris classification among seven Western expert endoscopists. A total of 85 short endoscopic video clips depicting polyps were created and assessed by seven expert endoscopists according to the Paris classification. After a digital training module, the same 85 polyps were assessed again. We calculated the interobserver agreement with a Fleiss kappa and as the proportion of pairwise agreement. The interobserver agreement of the Paris classification among seven experts was moderate with a Fleiss kappa of 0.42 and a mean pairwise agreement of 67%. The proportion of lesions assessed as "flat" by the experts ranged between 13 and 40% (P<0.001). After the digital training, the interobserver agreement did not change (kappa 0.38, pairwise agreement 60%). Our study is the first to validate the Paris classification for polyp morphology. We demonstrated only a moderate interobserver agreement among international Western experts for this classification system. Our data suggest that, in its current version, the use of this classification system in daily practice is questionable and it is unsuitable for comparative endoscopic research. We therefore suggest introduction of a simplification of the classification system.

Neural network classification of questionable EGRET events

Meetre, C. A.; Norris, J. P.

1992-02-01

High energy gamma rays (greater than 20 MeV) pair producing in the spark chamber of the Energetic Gamma Ray Telescope Experiment (EGRET) give rise to a characteristic but highly variable 3-D locus of spark sites, which must be processed to decide whether the event is to be included in the database. A significant fraction (about 15 percent or 104 events/day) of the candidate events cannot be categorized (accept/reject) by an automated rule-based procedure; they are therefore tagged, and must be examined and classified manually by a team of expert analysts. We describe a feedforward, back-propagation neural network approach to the classification of the questionable events. The algorithm computes a set of coefficients using representative exemplars drawn from the preclassified set of questionable events. These coefficients map a given input event into a decision vector that, ideally, describes the correct disposition of the event. The net's accuracy is then tested using a different subset of preclassified events. Preliminary results demonstrate the net's ability to correctly classify a large proportion of the events for some categories of questionables. Current work includes the use of much larger training sets to improve the accuracy of the net.

Looking at the ICF and human communication through the lens of classification theory.

PubMed

Walsh, Regina

2011-08-01

This paper explores the insights that classification theory can provide about the application of the International Classification of Functioning, Disability and Health (ICF) to communication. It first considers the relationship between conceptual models and classification systems, highlighting that classification systems in speech-language pathology (SLP) have not historically been based on conceptual models of human communication. It then overviews the key concepts and criteria of classification theory. Applying classification theory to the ICF and communication raises a number of issues, some previously highlighted through clinical application. Six focus questions from classification theory are used to explore these issues, and to propose the creation of an ICF-related conceptual model of communicating for the field of communication disability, which would address some of the issues raised. Developing a conceptual model of communication for SLP purposes closely articulated with the ICF would foster productive intra-professional discourse, while at the same time allow the profession to continue to use the ICF for purposes in inter-disciplinary discourse. The paper concludes by suggesting the insights of classification theory can assist professionals to apply the ICF to communication with the necessary rigour, and to work further in developing a conceptual model of human communication.

The dependence on morphology of the gas content in galactic disks

Hogg, D. E.; Roberts, M. S.

1993-01-01

The classification S0 was introduced by Hubble to serve as a description of galaxies whose morphological characteristics seemed to lie between the disk-dominated spirals and the spheroidal elliptical systems. Since then there has been extensive discussion as to whether this classification sequence is also an evolutionary sequence. Many studies have focussed on a particular feature such as the luminosity profile, the bulge-to-disk ratio, or the nature of the interstellar matter, but the question of the evolution remains contentious. Equally contentious is the question of the classification itself. For systems with well-developed disks there usually is no problem. Many spheroidal systems also are unambiguously classified as ellipticals in most catalogs. However, there are a number of early systems which have been reclassified following review using improved optical material. For example, Eder et al. (AJ, 102, 572, 1991) found that many of the S0 galaxies which are rich in neutral hydrogen have faint spiral features. The confusion about classification propagates into the discussion of the properties of early-type systems. Attempts to put the classification system on a quantitative basis have in general been unsuccessful. Recently Sandage (private communication) has reviewed the classification of early systems and has defined a set of sub-classes for these objects. The S0 galaxies are divided into three groups, depending on the prominence of the disk. There are six subdivisions of Sa galaxies, depending upon the relative prominence of knots and other arm-like characteristics. We have explored the total gas content in these objects to see if there is a dependence on the galaxy morphology, as denoted by these new subclasses.

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.

Both market research and literature reports both found that the ootheca of mantodea was all used as medicine. However, Chinese Pharmacopoeia only records the ootheca of three mantis species. The clinical use of ootheca unrecorded in Chinese Pharmacopoeia, will pose potential risks to drug safety. It's urgent to identify the origin of Mantidis Oötheca. The current researches about original animal in Mantidis Oötheca are based on morphology and unanimous. DNA barcoding fill gaps of the traditional morphological identification, which is widely used in animal classification studies. This study first use DNA barcoding to analyze genetic distance among different Mantidis Oötheca types, align COI sequences between mantis and Mantidis Oötheca and construct the phylogeny tree. The result confirmed that Tenodera sinensis and Hierodula patellifera were the origin insects of Tuanpiaoxiao and Heipiaoxiao, respectively, and Statilia maculate and Mantis religiosa were the origin insects of Changpiaoxiao.

Inspired by the enormous improvement of the visualization map propelled by the changed distances among the sentences, we being the first group utilizes the Word Mover's Distance(WMD) algorithm as a way of feature representation in Chinese text emotion classification. Our experiments show that both in 80% for training, 20% for testing and 50% for training, 50% for testing experiments of Ren_CECps, WMD features get the best f1 scores and have a greater increase compared with the same dimension feature vectors obtained by dimension reduction TF·IDF method. Compared experiments in English corpus also show the efficiency of WMD features in the cross-language field.

In order to enhance Chinese workers' occupational safety awareness, it is essential to learn from developed countries' experiences. This article investigates thoroughly occupational safety and health (OSH) in China and the UK; moreover, the article performs a comparison of Chinese and British OSH training-related laws, regulations and education system. The following conclusions are drawn: China's work safety continues to improve, but there is still a large gap compared with the UK. In China a relatively complete vocational education and training (VET) system has been established. However, there exist some defects in OSH. In the UK, the employer will not only pay attention to employees' physiological health, but also to their mental health. The UK's VET is characterized by classification and grading management, which helps integrate OSH into the whole education system. China can learn from the UK in the development of policies, VET and OSH training.

To describe the incidence and histologic patterns of eye cancers in Chinese in Taiwan. Beginning in 1979, cases of cancer in Taiwan were reported to the Taiwan National Cancer Registry. Information on all Chinese patients diagnosed with eye malignancies under the International Classification of Disease, Ninth Revision, site 190, was retrieved for analysis from the data bank of the Taiwan National Cancer Registry. In all, 733 cases with primary eye cancers were identified from 1979 to 1996, an 18-year period. The average annual age-standardized incidence of eye cancers was 2.46 per million population (2.57 for male and 2.33 for female). For cases less than 15 years of age, the most common eye malignancy was retinoblastoma (86.0%), followed by rhabdomyosarcoma (3.9%) and lymphoma (2.8%). For cases 15 years of age or older, the most common eye malignancy was melanoma (28.6%), followed by squamous cell sarcoma (21.0%) and lymphoma (20.8%). The time trends of the incidence of eye cancers were relatively stable over the 18-year period in Taiwan. Retinobalstoma, melanoma, and lymphoma were the three most common eye cancers in this Chinese population.

The NWRA Classification Infrastructure: description and extension to the Discriminant Analysis Flare Forecasting System (DAFFS)

2018-04-01

A classification infrastructure built upon Discriminant Analysis (DA) has been developed at NorthWest Research Associates for examining the statistical differences between samples of two known populations. Originating to examine the physical differences between flare-quiet and flare-imminent solar active regions, we describe herein some details of the infrastructure including: parametrization of large datasets, schemes for handling "null" and "bad" data in multi-parameter analysis, application of non-parametric multi-dimensional DA, an extension through Bayes' theorem to probabilistic classification, and methods invoked for evaluating classifier success. The classifier infrastructure is applicable to a wide range of scientific questions in solar physics. We demonstrate its application to the question of distinguishing flare-imminent from flare-quiet solar active regions, updating results from the original publications that were based on different data and much smaller sample sizes. Finally, as a demonstration of "Research to Operations" efforts in the space-weather forecasting context, we present the Discriminant Analysis Flare Forecasting System (DAFFS), a near-real-time operationally-running solar flare forecasting tool that was developed from the research-directed infrastructure.

Stereotyped movement disorder in ICD-11.

Stein, Dan J; Woods, Douglas W

2014-01-01

According to current proposals for ICD-11, stereotyped movement disorder will be classified in the grouping of neurodevelopmental disorders, with a qualifier to indicate whether self-injury is present, similar to the classification of stereotypic movement disorder in DSM-5. At the same time, the WHO ICD-11 Working Group on the Classification of Obsessive-Compulsive and Related Disorders has proposed a grouping of body-focused repetitive behavior disorders within the obsessive-compulsive and related disorders (OCRD) cluster to include trichotillomania and skin-picking disorder. DSM-5 has taken a slightly different approach: trichotillomania and excoriation (skin picking) disorder are included in the OCRD grouping, while body-focused repetitive behavior disorder is listed under other specified forms of OCRD. DSM-5 also includes a separate category of nonsuicidal self-injury in the section on "conditions for further study." There are a number of unresolved nosological questions regarding the relationships among stereotyped movement disorder, body-focused repetitive behavior disorders, and nonsuicidal self-injury. In this article, we attempt to provide preliminary answers to some of these questions as they relate to the ICD-11 classification of mental and behavioral disorders.

In this paper, we reconsider the context of Barbara Carper's alternative ways of knowing, a prominent discourse in modern nursing theory in North America. We explore this relative to the concepts of realism, non-realism and nominalism, and investigate the philosophical divisions behind the original typology, particularly in relationship to modern scientific enquiry. We examine forms of knowledge relative to realist and nominalist positions and make an argument ad absurdum against relativistic interpretations of knowledge using the example of Borge's Chinese Emporium of Benevolent Knowledge. We propose a contentious postpositivist practical classification for nursing knowledge that demonstrates and supports the idea that knowledge has both individual and subjective components. This classification supports the practical application of nursing knowledge within the paradigm of realist postpositivist science. © 2014 John Wiley & Sons Ltd.

Conflicting data from neurobehavioral studies of the perception of intonation (linguistic) and emotion (affective) in spoken language highlight the need to further examine how functional attributes of prosodic stimuli are related to hemispheric differences in processing capacity. Because of similarities in their acoustic profiles, intonation and emotion permit us to assess to what extent hemispheric lateralization of speech prosody depends on functional instead of acoustical properties. To examine how the brain processes linguistic and affective prosody, an fMRI study was conducted using Chinese, a tone language in which both intonation and emotion may be signaled prosodically, in addition to lexical tones. Ten Chinese and 10 English subjects were asked to perform discrimination judgments of intonation (I: statement, question) and emotion (E: happy, angry, sad) presented in semantically neutral Chinese sentences. A baseline task required passive listening to the same speech stimuli (S). In direct between-group comparisons, the Chinese group showed left-sided frontoparietal activation for both intonation (I vs. S) and emotion (E vs. S) relative to baseline. When comparing intonation relative to emotion (I vs. E), the Chinese group demonstrated prefrontal activation bilaterally; parietal activation in the left hemisphere only. The reverse comparison (E vs. I), on the other hand, revealed that activation occurred in anterior and posterior prefrontal regions of the right hemisphere only. These findings show that some aspects of perceptual processing of emotion are dissociable from intonation, and, moreover, that they are mediated by the right hemisphere.

The development of nursing information systems (NIS) is often hampered by the fact that nursing lacks a unified nursing terminology and classification system. Currently there exist various initiatives in this area. We address the question as to how current initiatives in the development of nursing terminology and classification systems can contribute towards the development of NIS. First, the rationale behind the formalization of nursing knowledge is discussed. Next, using a framework for nursing information processing, the most important developments in the field of nursing on formalization, terminology and classification are critically reviewed. The initiatives discussed include nursing terminology projects in several countries, and the International Classification of Nursing Practice. Suggestions for further developments in the area are discussed. Finally, implications for NIS are presented, as well as the relationships of these components to other sections of an integrated computerized patient record.

The seabed deposits type and distribution are very complex at the hydrothermal field. In this paper, we provided an approach to study the seabed deposits classification at the Precious Stone Mountain hydrothermal field (PSMHF) using MultiBeam sonar data (Figure 1). The PSMHF was found in the Galapogas microplate at the Leg 3 of the Chinese COMRA 21st Cruise. Using this approach, the seabed deposits at the PSMHF are mainly classified into three types, which are rock, breccia and sediment, respectively. We can find the distribution of the three types of seabed deposits according to the sonar back-scattering data. The rocks are mostly distributed around the hydrothermal vent. The breccia are located at the foot of the vent. Most sediments are distributed at the southwest to the vent due to bottom current. Combining with seabed video, TV-Grab sample and the backscatter data, we draw the map of the seabed deposits distribution at the PSMHF (Figure 2).

Following the fact that a large collection of ink and wash paintings (IWP) is being digitized and made available on the Internet, their automated content description, analysis, and management are attracting attention across research communities. While existing research in relevant areas is primarily focused on image processing approaches, a style-based algorithm is proposed to classify IWPs automatically by their authors. As IWPs do not have colors or even tones, the proposed algorithm applies edge detection to locate the local region and detect painting strokes to enable histogram-based feature extraction and capture of important cues to reflect the styles of different artists. Such features are then applied to drive a number of neural networks in parallel to complete the classification, and an information entropy balanced fusion is proposed to make an integrated decision for the multiple neural network classification results in which the entropy is used as a pointer to combine the global and local features. Evaluations via experiments support that the proposed algorithm achieves good performances, providing excellent potential for computerized analysis and management of IWPs.

Feature selection is a practical approach for improving the performance of text classification methods by optimizing the feature subsets input to classifiers. In traditional feature selection methods such as information gain and chi-square, the number of documents that contain a particular term (i.e. the document frequency) is often used. However, the frequency of a given term appearing in each document has not been fully investigated, even though it is a promising feature to produce accurate classifications. In this paper, we propose a new feature selection scheme based on a term event Multinomial naive Bayes probabilistic model. According to the model assumptions, the matching score function, which is based on the prediction probability ratio, can be factorized. Finally, we derive a feature selection measurement for each term after replacing inner parameters by their estimators. On a benchmark English text datasets (20 Newsgroups) and a Chinese text dataset (MPH-20), our numerical experiment results obtained from using two widely used text classifiers (naive Bayes and support vector machine) demonstrate that our method outperformed the representative feature selection methods.

Background: The motivation for this work is built upon the premise that there is a need for research-based materials for design-based science instruction. In this paper, a small portion of our work investigating the impact of a LEGOTM engineering unit on fourth grade students' preconceptions and understanding of animals is presented. Purpose: The driving questions for our work are: (1) What is the impact of an engineering-design-based curricular module on students' understanding of habitat and animal classification? (2) What are students' misconceptions regarding animal classification and habitat? Sample: The study was conducted in an inner-city K-8 school in the northeastern region of the United States. There were two fourth grade classrooms in the school. The first classroom included seven girls and nine boys, whereas the other classroom included eight girls and eight boys. All fourth grade students participated in the study. Design and methods: In answering the research questions mixed-method approaches are used. Data collection methods included pre- and post-tests, pre- and post-interviews, student journals, and classroom observations. Identical pre- and post-tests were administered to measure students' understanding of animals. They included four multiple-choice and six open-ended questions. Identical pre- and post-interviews were administered to explore students' in-depth understanding of animals. Results: Our results show that students significantly increased their performance after instruction on both the multiple-choice questions (t = -3.586, p = .001) and the open-ended questions (t = -5.04, p = .000). They performed better on the post interviews as well. Also, it is found that design-based instruction helped students comprehend core concepts of a life science subject, animals. Conclusions: Based on these results, the main argument of the study is that engineering design is a useful framework for teaching not only physical science-related subjects, but also life science subjects in elementary science classrooms.

ABSTRACTOBJECTIVETo develop a classification of complementary and alternative medicine (CAM) practices widely available in Canada based on physicians' effectiveness ratings of the therapies.DESIGNA self-administered postal questionnaire asking family physicians to rate their "belief in the degree of therapeutic effectiveness" of 15 CAM therapies.SETTINGProvince of Alberta.PARTICIPANTSA total of 875 family physicians.MAIN OUTCOME MEASURESDescriptive statistics of physicians' awareness of and effectiveness ratings for each of the therapies; factor analysis was applied to the ratings of the 15 therapies in order to explore whether or not the data support the proposed classification of CAM practices into categories of accepted and rejected.RESULTSPhysicians believed that acupuncture, massage therapy, chiropractic care, relaxation therapy, biofeedback, and spiritual or religious healing were effective when used in conjunction with biomedicine to treat chronic or psychosomatic indications. Physicians attributed little effectiveness to homeopathy or naturopathy, Feldenkrais or Alexander technique, Rolfing, herbal medicine, traditional Chinese medicine, and reflexology. The factor analysis revealed an underlying dimensionality to physicians' effectiveness ratings of the CAM therapies that supports the classification of these practices as either accepted or rejected.CONCLUSIONThis study provides Canadian family physicians with information concerning which CAM therapies are generally accepted by their peers as effective and which are not.

A novel, simple and direct fluorescence method for analysis of complex substances and their potential substitutes has been researched and developed. Measurements involved excitation and emission (EEM) fluorescence spectra of powdered, complex, medicinal herbs, Cortex Phellodendri Chinensis (CPC) and the similar Cortex Phellodendri Amurensis (CPA); these substances were compared and discriminated from each other and the potentially adulterated samples (Caulis mahoniae (CM) and David poplar bark (DPB)). Different chemometrics methods were applied for resolution of the complex spectra, and the excitation spectra were found to be the most informative; only the rank-ordering PROMETHEE method was able to classify the samples with single ingredients (CPA, CPC, CM) or those with binary mixtures (CPA/CPC, CPA/CM, CPC/CM). Interestingly, it was essential to use the geometrical analysis for interactive aid (GAIA) display for a full understanding of the classification results. However, these two methods, like the other chemometrics models, were unable to classify composite spectral matrices consisting of data from samples of single ingredients and binary mixtures; this suggested that the excitation spectra of the different samples were very similar. However, the method is useful for classification of single-ingredient samples and, separately, their binary mixtures; it may also be applied for similar classification work with other complex substances.
