PubMed

1997-04-01

1996 statistics released by China's State Statistical Bureau reflect the level of social development. Statistics are provided on education, health, population, income, employment, housing, social welfare, and environmental degradation. The number of higher education institutions declined slightly between 1995 and 1996. In 1996 there were 1032 universities and colleges and 1138 adult education higher learning institutions. The number of students enrolled in universities and colleges increased by 40,000 to 966,000. The total university population numbered 3.02 million in 1996. Increases in students occurred in adult education and graduate schools. Secondary vocational education expanded to 10.1 million students, or 56.8% of all senior middle school students. The 50.48 million junior middle school students represent an enrollment rate of 82.4%. The 136.15 million primary school students represent a 98.8% enrollment rate. About 4.07 million adults gained literacy. Preventive health work and rural public health work were strengthened in 1996. The birth rate in 1996 was 16.98/1000. The death rate was 6.56/1000. The 1996 end-of-the-year population was 1.22389 billion, an increase of 12.68 million over 1995. 29.4% were urban residents. The average family size was 3.70. 26.4% were children aged 0-14 years, and 9.4% were aged over 65 years. The average annual disposable income per capita was 4839 yuan for urban residents, 6235 yuan in provincial capital cities, and 1926 yuan for rural residents. Rural residents received the highest increase in income (9%) at constant prices. 688.5 million people were employed, of which 149.6 million were urban workers. The labor force increased by 9 million people during the year. 360 million sq. m of new buildings were added in urban areas in 1996; 760 million sq. m were added in rural areas.

Neonatal hearing screening (NHS) has been routinely offered as a vital component of early childhood care in developed countries, whereas such a screening program is still at the pilot or preliminary stage as regards its nationwide implementation in developing countries. To provide significant evidence for health policy making in China, this study aims to determine the cost-effectiveness of NHS program implementation in case of eight provinces of China. A cost-effectiveness model was conducted and all neonates annually born from 2007 to 2009 in eight provinces of China were simulated in this model. The model parameters were estimated from the established databases in the general hospitals or maternal and child health hospitals of these eight provinces, supplemented from the published literature. The model estimated changes in program implementation costs, disability-adjusted life years (DALYs), average cost-effectiveness ratio (ACER), and incremental cost-effectiveness ratio (ICER) for universal screening compared to targeted screening in eight provinces. A multivariate sensitivity analysis was performed to determine uncertainty in health effect estimates and cost-effectiveness ratios using a probabilistic modeling technique. Targeted strategy trended to be cost-effective in Guangxi, Jiangxi, Henan, Guangdong, Zhejiang, Hebei, Shandong, and Beijing from the level of 9%, 9%, 8%, 4%, 3%, 7%, 5%, and 2%, respectively; while universal strategy trended to be cost-effective in those provinces from the level of 70%, 70%, 48%, 10%, 8%, 28%, 15%, 4%, respectively. This study showed although there was a huge disparity in the implementation of the NHS program in the surveyed provinces, both universal strategy and targeted strategy showed cost-effectiveness in those relatively developed provinces, while neither of the screening strategy showed cost-effectiveness in those relatively developing provinces. This study also showed that both strategies especially universal strategy achieve a good economic effect in the long term costs. Universal screening might be considered as the prioritized implementation goal especially in those relatively developed provinces of China as it provides the best health and economic effects, while targeted screening might be temporarily more realistic than universal screening in those relatively developing provinces of China.

This paper has briefly analyzed the publication status of Chinese stomatology papers in 2009 with statistics from Journal Citation Reports provided by Thomson Scientific. Only those papers with the first author coming from the mainland of China were included for calculations. We have found a significant increase in the number of SCIE-indexed papers, most of which were published by six dental institutions in China. Among all Chinese medical institutions, West China School of Stomatology Sichuan University is the first dental institution to enter the top-20 list with the most publications, and it also ranks the 9th in the number of outstanding articles. West China School of Stomatology Sichuan University and the Forth Military Medical University are the only two dental institutions in China which have published SCIE-indexed papers over a hundred. The former has published the most SCIE-indexed stomatology papers, while the latter has the highest average impact factor. As the laboratories and funds in China have close connections with various dental hospitals, the pratice of translational medicine in dentistry is fast and fluent.

Migraine is one of the most common primary headache disorders and is burdensome to both the individual and society, influencing the academic performance and quality of daily lives of medical students worldwide. This study aimed to investigate the migraine prevalence in a sample of university medical students in China and to examine the features and typical trigger factors of migraine among these students. From May 2016 to August 2016, a total of 1,060 medical students who were enrolled in Soochow University in Jiangsu Province in China were chosen through stratified random sampling. A self-administered questionnaire that included the ID Migraine™ for screening of migraine cases was used to collect data. The frequency, severity, duration of migraine attacks, and relevant trigger factors were measured for migraine cases. In total, 986 students completed the questionnaire. The overall migraine prevalence among students was 7.91%, with 4.64% in male and 9.84% in female students. Junior-grade students had a higher migraine prevalence than senior students (prevalence of migraine of year 1 to year 5 undergraduates: 10.83%, 8.9% vs. 6.25%, 4.42%, 5.33%, P <0.05; prevalence of migraine of year 1 to year 3 graduates: 9.68%, 9.71% vs. 6.38%, P <0.05). Students with a positive family history were more likely to suffer migraine than those without (OR=8.48, 95% CI: 4.33-16.59). Stress (n=73, 93.59%), lack of sleep (n=72, 92.31%), and change of sleeping time (n=68, 87.18%) were the top three trigger factors among the students. Migraine was common among medical students from a university in China, and especially higher in female and junior-grade students, and those with a family history of migraine. Reducing stress and improving sleep quality might be effective to reduce migraine attacks in this population.

Indian meal moth Plodia interpunctella Hübner (Lepidoptera: Pyralidae) is considered as an important insect pest infesting stored grains and other products in China. The major sex pheromone component of P. interpunctella, Z9, E12-14: OAc (TDA), has already been identified. Though the efficiency of male capture by using the bait with this component alone is quite good, the pheromone system is far from fully understood. The identification with capillary chromatographic analysis and GC-MS methods showed that there were four main components, i. e., Z9, E12-14: OAc(A), Z9, E12-14: OH (B), Z9, E12-14: Ald(C), and Z9-14: OAc(D), in the sex pheromone gland of female P. interpunctella, and the ratio of these four components was A: B: C:D= 100:22: 12:9. Wind tunnel experimental results suggested that the response of male P. interpunctella to a blend (A: B: C: D = 8:2:1:0.8) was not significantly different from that to female sex pheromone gland extracts.

2017-06-01

The spin-boson model with quadratic coupling is studied using the bosonic numerical renormalization group method. We focus on the dynamical auto-correlation functions {C}O(ω ), with the operator \\hat{O} taken as {\\hat{{{σ }}}}x, {\\hat{{{σ }}}}z, and \\hat{X}, respectively. In the weak-coupling regime α < {α }{{c}}, these functions show power law ω-dependence in the small frequency limit, with the powers 1+2s, 1+2s, and s, respectively. At the critical point α ={α }{{c}} of the boson-unstable quantum phase transition, the critical exponents y O of these correlation functions are obtained as {y}{{{σ }}x}={y}{{{σ }}z}=1-2s and {y}X=-s, respectively. Here s is the bath index and X is the boson displacement operator. Close to the spin flip point, the high frequency peak of {C}{{{σ }}x}(ω ) is broadened significantly and the line shape changes qualitatively, showing enhanced dephasing at the spin flip point.

In this work, negative dielectric nematic liquid crystal SLC12V620-400, chiral dopant S811, and laser dye DCM are used to prepare dye-doped chiral nematic liquid crystal laser sample. In order to investigate temperature-tunable lasing in negative dielectric chiral nematic liquid crystal, we measure the transmission and lasing spectrum of this sample. The photonic band gap (PBG) is observed to red shift with its width reducing from 71.2 nm to 40.2 nm, and its short-wavelength band edge moves 55.3 nm while the long-wavelength band edge only moves 24.9 nm. The wavelength of output laser is found to red shift from 614.4 nm at 20 °C to 662.8 nm at 67 °C, which is very different from the previous experimental phenomena. The refractive indices, parallel and perpendicular to the director in chiral nematic liquid crystal have different dependencies on temperature. The experiment shows that the pitch of this chiral nematic liquid crystal increases with the increase of temperature. The decrease in the PBG width, different shifts of band edges, and the red shift of laser wavelength are the results of refractive indices change and pitch thermal elongation.

Theileria parasites are important tick-borne pathogens of animals and cause huge economic losses worldwide. Here, we undertook to assess the prevalence of Theileria spp. in cervids in Gansu, China, based on PCR analysis and sequencing of the 18S rRNA genes. Molecular survey showed that Theileria luwenshuni and Theileria sp. RSR were frequently found in Gansu cervids, and the prevalence of T. luwenshuni was 66.7% (n = 9, 6/9) in roe deer in Zhengning County, 58.3% (n = 12, 7/12) in sika deer in Ningxian County, 50% (n = 10, 5/10) in sika deer and 42.9% (n = 14, 6/14) in red deer in Weiyuan County. The prevalence of Theileria sp. RSR was 77.8% (n = 9, 7/9) in roe deer in Zhengning County, 75% (n = 12, 9/12) in sika deer in Ningxian County, 60.0% (n = 10, 6/10) in sika deer, and 50.0% (n = 14, 7/14) in red deer in Weiyuan County. The co-prevalence of the two T. luwenshuni and Theileria sp. RSR was 55.6% (n = 5, 5/9) in roe deer in Zhengning County, 50% (n = 12, 6/12) in sika deer in Ningxian county, 50% (n = 10, 5/10) in sika deer and 35.7% (n = 14, 5/14) in red deer in Weiyuan County, respectively. No other Theileria species was found in these samples. T. luwenshuni and Theileria sp. RSR were detected for the first time in cervids in Gansu, China. Animal experiments showed that four sheep were inoculated with roe deer blood from Zhengning, sika deer blood from Ningxian, sika deer blood, and red deer blood from Weiyuan, respectively, and the Theileria isolated from these inoculated sheep was identified as T. luwenshuni, but Theileria sp. RSR was not detected in these sheep. Our results extend our understanding of the epidemiology of cervine theileriosis in Gansu, China, and will facilitate the implementation of measures to control theileriosis in cervids and small ruminants. This was the first report to demonstrate the occurrence of T. luwenshuni from roe deer, sika deer, and red deer worldwide.

Universal salt iodisation (USI) has been successfully implemented in China for more than 15 years. Recent evidence suggests that the definition of 'adequate iodine' (100-199 µg/l) be revised to 'sufficient iodine' (100-299 µg/l) based on the median urinary iodine concentration (MUI) in school-age children. The objective of this study was to determine the prevalence of thyroid dysfunction in populations after long-term salt iodisation and examine whether the definition of adequate iodine can be broadened to sufficient iodine based on the thyroid function in four population groups. A cross-sectional survey was conducted in six provinces in the northern, central and southern regions of China. Four population groups consisting of 657 children, 755 adults, 347 pregnant women and 348 lactating women were recruited. Three spot urinary samples were collected over a 10-d period and blood samples were collected on the 1st day. In the study, among the adults, pregnant women and lactating women, the prevalence rates of elevated thyroglobulin antibody and thyroid microsomal antibody levels were 12·4, 8·5 and 7·8 %, and 12·1, 9·1 and 9·1 %, respectively. Abnormally high thyroid dysfunction prevalence was not observed after more than 15 years of USI in China because the thyroid dysfunction rates were all <5 %. The recommended range should be cautiously broadened from adequate iodine to sufficient iodine according to the MUI of school-age children considering the high levels of hormones and antibodies in the other populations. Adults, particularly pregnant women positive for thyroid antibodies, should be closely monitored.

Poor air quality has become a national public health concern in China. This study examines the impact of ambient fine particulate matter (PM 2.5 ) air pollution on health behaviors among college students in Beijing, China. Prospective cohort study. Health surveys were repeatedly administered among 12,000 newly admitted students at Tsinghua University during 2012-2015 over their freshman year. Linear individual fixed-effect regressions were performed to estimate the impacts of ambient PM 2.5 concentration on health behaviors among survey participants, adjusting for various time-variant individual characteristics and environmental measures. Ambient PM 2.5 concentration was found to be negatively associated with time spent on walking, vigorous physical activity and sedentary behavior in the last week, but positively associated with time spent on nighttime/daytime sleep among survey participants. An increase in the ambient PM 2.5 concentration by one standard deviation (36.5 μg/m³) was associated with a reduction in weekly total minutes of walking by 7.3 (95% confidence interval [CI] = 5.3-9.4), a reduction in weekly total minutes of vigorous physical activity by 10.1 (95% CI = 8.5-11.7), a reduction in daily average hours of sedentary behavior by 0.06 (95% CI = 0.02-0.10) but an increase in daily average hours of nighttime/daytime sleep by 1.07 (95% CI = 1.04-1.11). Ambient PM 2.5 air pollution was inversely associated with physical activity level but positively associated with sleep duration among college students. Future studies are warranted to replicate study findings in other Chinese cities and universities, and policy interventions are urgently called to reduce air pollution level in China's urban areas.

BACKGROUND The aim of this study was to explore the relationship between physical performance and BMI (body mass index) of university students in China. MATERIAL AND METHODS We conducted a cross-sectional study evaluating the physical performance and BMI of university students. BMI was calculated based on height and weight. Overweight and obesity were defined by the Working Group on Obesity references in China. RESULTS A total of 2313 participants (978 males and 1335 females) were recruited in our study. The mean value of the 50-meter dash and standing long jump in male students was higher than in female students (P<0.05). The overall prevalences of overweight (including obesity) and obesity for male students were 17.9% and 4.2%, respectively, and 5.1% and 0.5%, respectively, for female university students. BMI was weakly positively associated with the 50-meter dash score, but was negatively associated with the score for standing long jump and pull-ups. CONCLUSIONS Our study suggested that overweight and obesity are associated with physical performance of university students, especially in male students. University students should exercise more to improve physical health.

We study the photon statistics of pulse-pumped four-wave mixing in fibers with weak coherent signal injection by measuring the intensity correlation functions of individual signal and idler fields. The experimental results show that the intensity correlation function of individual signal (idler) field decreases with the intensity of signal injection. After applying narrow band filter in signal (idler) band, the value of decreases from 1.9 ± 0.02 (1.9 ± 0.02) to 1.03 ± 0.02 (1.05 ± 0.02) when the intensity of signal injection varies from 0 to 120 photons/pulse. The results indicate that the photon statistics changes from Bose-Einstein distribution to Poisson distribution. We calculate the intensity correlation functions by using the multi-mode theory of four-wave mixing in fibers. The theoretical curves well fit the experimental results. Our investigation will be useful for mitigating the crosstalk between quantum and classical channels in a dense wavelength division multiplexing network.

H9N2 avian influenza virus (AIV) has caused significant losses in chicken flocks throughout china in recent years. There is a limited understanding of the genetic and antigenic characteristics of the H9N2 virus isolated in chickens in southwestern China. In this study a total of 12 field strains were isolated from tissue samples from diseased chickens between 2013 and 2016. Phylogenetic analysis of the Hemagglutinin (HA) and Neuraminidase (NA) nucleotide sequences from the 12 field isolates and other reference strains showed that most of the isolates in the past four years could be clustered into a major branch (HA-branch A and NA-branch I) in the Clade h9.4.2 lineages. These sequences are accompanied by nine and seven new amino acids mutations in the HA and NA proteins, respectively, when compared with those previous to 2013. In addition, four new isolates were grouped into a minor branch (HA-branch B) in the Clade h9.4.2 lineages and two potential N-glycosylation sites were observed due to amino acid mutations in the HA protein. Three antigenic groups (1–3), which had low antigenic relatedness with two commonly used vaccines in China, were identified among the 12 isolates by antigenMap analysis. Immunoprotection testing showed that those two vaccines could efficiently prevent the shedding of branch A viruses but not branch B viruses. In conclusion, these results indicate the genotype of branch B may become epidemic in the next few years and that a new vaccine should be developed for the prevention of H9N2 AIV. PMID:28158271

China is increasingly facing the challenge of control of the growing burden of non-communicable diseases. We assessed the epidemiology of Alzheimer's disease and other forms of dementia in China between 1990, and 2010, to improve estimates of the burden of disease, analyse time trends, and inform health policy decisions relevant to China's rapidly ageing population. In our systematic review we searched for reports of Alzheimer's disease or dementia in China, published in Chinese and English between 1990 and 2010. We searched China National Knowledge Infrastructure, Wanfang, and PubMed databases. Two investigators independently assessed case definitions of Alzheimer's disease and dementia: we excluded studies that did not use internationally accepted case definitions. We also excluded reviews and viewpoints, studies with no numerical estimates, and studies not done in mainland China. We used Poisson regression and UN demographic data to estimate the prevalence (in nine age groups), incidence, and standardised mortality ratio of dementia and its subtypes in China in 1990, 2000, and 2010. Our search returned 12,642 reports, of which 89 met the inclusion criteria (75 assessed prevalence, 13 incidence, and nine mortality). In total, the included studies had 340,247 participants, in which 6357 cases of Alzheimer's disease were recorded. 254,367 people were assessed for other forms of dementia, of whom 3543 had vascular dementia, frontotemporal dementia, or Lewy body dementia. In 1990 the prevalence of all forms of dementia was 1·8% (95% CI 0·0-44·4) at 65-69 years, and 42·1% (0·0-88·9) at age 95-99 years. In 2010 prevalence was 2·6% (0·0-28·2) at age 65-69 years and 60·5% (39·7-81·3) at age 95-99 years. The number of people with dementia in China was 3·68 million (95% CI 2·22-5·14) in 1990, 5·62 million (4·42-6·82) in 2000, and 9·19 million (5·92-12·48) in 2010. In the same period, the number of people with Alzheimer's disease was 1·93 million (1·15-2·71) in 1990, 3·71 million (2·84-4·58) people in 2000, and 5·69 million (3·85-7·53) in 2010. The incidence of dementia was 9·87 cases per 1000 person-years, that of Alzheimer's disease was 6·25 cases per 1000 person-years, that of vascular dementia was 2·42 cases per 1000 person-years, and that of other rare forms of dementia was 0·46 cases per 1000 person-years. We retrieved mortality data for 1032 people with dementia and 20,157 healthy controls, who were followed up for 3-7 years. The median standardised mortality ratio was 1·94:1 (IQR 1·74-2·45). Our analysis suggests that previous estimates of dementia burden, based on smaller datasets, might have underestimated the burden of dementia in China. The burden of dementia seems to be increasing faster than is generally assumed by the international health community. Rapid and effective government responses are needed to tackle dementia in low-income and middle-income countries.

Due to the changes in lifestyle and dietary behaviors, the incidence of colorectal cancer (CRC) has been rapidly increasing in China. This study is to present the trends of CRC in China over the past decade. It used a series of nationally representative data, including the National Central Cancer Registry of China, the GLOBOCAN project and the Global Burden of Disease. The age-standardized rate of CRC incidence increased from 12.8 in 2003 to 16.8 per 100,000 in 2011, while the mortality rose from 5.9 to 7.8 per 100,000. The age group most affected by incident CRC cases were those aged 60-74 years old, whereas CRC death was most associated with those >74 years. Furthermore, the east coast of China presented a higher mortality rate (>15 and 10-14.9 per 100,000 in men and women) than central and west China (5-14.9 and 5-9.9 per 100,000). Compared with other countries worldwide, China indicated lower rates of incidence (14.2 per 100,000), mortality (7.4 per 100,000), and 5-year prevalence (52.7 per 100,000) than most developed countries. However, China had a higher case-fatality ratio (14.0 %) and mortality/incidence ratio (52.1 %). Lastly, disability-adjusted life years attributed to CRC in China was 224.2 per 100,000. It presents a steady increase in CRC in China over the past decade. It also reveals the domestic diversity of age, gender, and geography and finds the differences between China and developed countries, which may yield insights for national programs and policies.

To study the current status of spontaneous abortion of primigravid women in Jiaxing areas of Zhejiang province of China. We analyzed the data from both perinatal healthcare surveillance program and spontaneous abortion, collected in Jiaxing areas by the Institute of Reproductive and Child Health, Peking University. The study population consisted of 14 769 primigravid women (excluding induced abortion, ectopic pregnancy and molar pregnancy as outcomes) attempting to become pregnant who registered between 1993 and 1995. 1454 spontaneous abortion cases were identified, with the spontaneous abortion rate as 9.8% (95%CI: 9.3% - 10.3%). The mean gestational weeks at pregnancy diagnosis were 7.6 ± 2.1 weeks, the mean gestational weeks at miscarriage were (10.1 ± 3.1) weeks and the incidence of first-trimester (≤ 12 weeks) spontaneous abortion was 7.3% (95%CI: 6.8% - 7.7%), accounting for 73.7% of all the spontaneous abortion cases. A peak for risk of miscarriage was around 8 - 13 weeks, accounting for 37.7% of all spontaneous abortion. The observed multiple Cox regression model showed that increased spontaneous abortion rates were observed in women with age at pregnancy ≥ 30, being peasants and with higher education level. The spontaneous abortion rate of primigravid women in Jiaxing areas was higher than in other areas of China. The maximum occurrence of spontaneous abortions was during period of 8-13 gestation weeks.

Cryptosporidium and Giardia are ubiquitous parasites that infect humans and animals. Few reports are available on the prevalence of these two protozoan parasites in yaks (Bos grunniens). In this study, 344 faecal samples were collected from yaks with diarrhoea in the Chenduo and Nangqian counties of Qinghai Province, China. Cryptosporidium spp. and Giardia duodenalis were detected by light and immunofluorescence microscopy and nested PCR (nPCR). Fifteen samples were positive (4.5%) by Kinyoun staining, 40 (11.6%) samples were positive by immunofluorescence test (IFT), and 39 (11.3%) samples were positive by nPCR for Cryptosporidium spp., Cryptosporidium bovis (11/39, 28.2%) was the most prevalent species, followed by C. ryanae (6/39, 15.4%), C. andersoni (5/39, 12.8%), C. struthionis (5/39, 12.8%), C. parvum (5/39, 12.8%), C. hominis (4/39, 10.3%) and C. canis (3/39, 7.7%). Thirteen out of 344 (3.8%) samples were positive for Giardia by simple microscopy, 20 (5.8%) by IFT and 18 samples (5.2%) yak faecal samples were Giardia positive by nPCR. Two G. duodenalis assemblages (B, E) were detected in this study. Nine positive samples for G. duodenalis assemblage E were from the towns of Xiewu (8/9, 4.9%) and Xiangda (1/9, 1.3%), and nine positive samples (9/9, 8.5%) for G. duodenalis assemblage B were from the town of Zhenqin. This report provides information about infection with Cryptosporidium species and G. duodenalis assemblages in domesticated 1-2-month-old highland yaks living in the Qinghai-Tibet Plateau region of China.

Essential oils of the resins of Pinus brutia and Pinus pinea were evaluated for their biological potential. Essential oils were characterized using GC-MS and GC/FID. in vitro antimicrobial, phytotoxic, antioxidant, and insecticidal activities were carried out using the direct contact and the fumigant assays, respectively. The chemical profile of the essential oils of the resins of P. pinea and P. brutia included mainly α-pinene (21.39% and 25.40%), β-pinene (9.68% and 9.69%), and caryophyllene (9.12% and 4.81%). The essential oils of P. pinea and P. brutia exerted notable antimicrobial activities on Micrococcus luteus and Bacillus subtilis, insecticidal activities on Ephestia kuehniella eggs, phytotoxic activities on Lactuca sativa, Lepidium sativum, and Portulaca oleracea, as well as antioxidant potential. Indications of the biological activities of the essential oils suggest their use in the formulation of ecofriendly and biocompatible pharmaceuticals. Copyright © 2014 China Pharmaceutical University.

It is critical to understand environmental impacts embodied in the bilateral trade between China and the United States, given the political, economic, and geographical importance of the two countries and the fact that few studies have investigated this before. This article studies the environmental impacts, particularly energy consumption and air emissions, embodied in the eastbound (from China to the U.S.) trade from 2002 to 2007 using an environmental input-output analysis technique and the adjusted bilateral trade data. In general,trade volume increased until the panic of 2008, and shifting trade patterns cause fluctuating embodied energy and air emissions in trade in China. Results show that embodied energy ranges from 7 to 11 exajoule (EJ) and takes about 12-17% of China's energy consumption. Embodied CO2 ranges between 400 and 800 Mt and represents about 8-12% of China's CO2 emissions. SO2 and NOx embodied in the eastbound trade generally grow over this period, from 4.2 to 6.3 Mt and from 1.4 to 2.9 Mt and account for 10-15% and 8-12% of China's total emissions, respectively.

The health care system reform in the People's Republic of China has brought plans for establishment of a universal coverage for basic health services, including services for children. This effort demands significant change in health care planning. Pediatric emergency medicine (PEM) is not currently identified as a specialty in China, and emergency medicine systems suffer from lack of appropriate training.In 2006, the Centre for International Child Health and the Department of Pediatrics, British Columbia Children's Hospital, Vancouver, Canada, initiated a fellowship training program in PEM for pediatricians working in emergency departments or critical care settings with the Children's Hospital of Fudan University, China. The main objective was to upgrade the professional and clinical experience of emergency physicians practicing PEM and build PEM capacity throughout China by training the future trainers. After selecting trainees, the program included a structured curriculum over 2 years of training in China by Canadian and Australian PEM faculty and then practical exposure to PEM in Canada. All trainees underwent a structured evaluation after their final rotation in Canada. A total of 12 trainees completed the first 2 program cycles. The trainees considered the "overall rating of the training experience" as "excellent" (10/12) or "good" (2/12). All trainees considered the program as a relevant training to their practice and felt it will change their practice. They reported the program to be effective, with excellent complexity of content. Despite its current success, the program faces challenges in the development of the new subspecialty and ensuring its acceptance among other health care providers and decision makers. Identification and preparation of a capable training force to lead educational activities in China are daunting tasks. Time constraints, funding, and language barriers are other challenges. Future effort should be focused on improving and sustaining resuscitation capacity and enhancing triage systems.

Introduction Migrants are a vulnerable population and could experience various challenges and barriers to accessing health insurance. Health insurance coverage protects migrants from financial loss related to illness and death. We assessed social health insurance (SHI) coverage and its financial protection effect among rural-to-urban internal migrants (IMs) in China. Methods Data from the ‘2014 National Internal Migrant Dynamic Monitoring Survey’ were used. We categorised 170 904 rural-to-urban IMs according to their SHI status, namely uninsured by SHI, insured by the rural SHI scheme (new rural cooperative medical scheme (NCMS)) or the urban SHI schemes (urban employee-based basic medical insurance (UEBMI)/urban resident-based basic medical insurance (URBMI)), and doubly insured (enrolled in both rural and urban schemes). Financial protection was defined as ‘the percentage of out-of-pocket (OOP) payments for the latest inpatient service during the past 12 months in the total household expenditure’. Results The uninsured rate of SHI and the NCMS, UEBMI/URBMI and double insurance coverage in rural-to-urban IMs was 17.3% (95% CI 16.9% to 17.7%), 66.6% (66.0% to 67.1%), 22.6% (22.2% to 23.0%) and 5.5% (5.3% to 5.7%), respectively. On average, financial protection indicator among uninsured, only NCMS insured, only URBMI/UEBMI insured and doubly insured participants was 13.3%, 9.2%, 6.2% and 5.8%, respectively (p=0.004). After controlling for confounding factors and adjusting the protection effect of private health insurance, compared with no SHI, the UEBMI/URBMI, the NCMS and double insurance could reduce the average percentage share of OOP payments by 33.9% (95% CI 25.5% to 41.4%), 14.1% (6.6% to 20.9%) and 26.8% (11.0% to 39.7%), respectively. Conclusion Although rural-to-urban IMs face barriers to accessing SHI schemes, our findings confirm the positive financial protection effect of SHI. Improving availability and portability of health insurance would promote financial protection for IMs, and further facilitate achieving universal health coverage in China and other countries that face migration-related obstacles to achieve universal coverage.

China's national health policy classifies depression as a chronic disease that should be managed in primary care settings. In some high-income countries use of chronic disease management principles and primary care-based collaborative-care models have improved outcomes for late-life depression; however, this approach has not yet been tested in China. We aimed to assess whether use of a collaborative-care depression care management (DCM) intervention could improve outcomes for Chinese adults with depression aged 60 years and older. Between Jan 17, 2011, [corrected] and Nov 30, 2013, we did a cluster-randomised trial in patients from primary care centre clinics in Shangcheng district of Hangzhou city in eastern China. We randomly assigned (1:1) clinics to either DCM (involving training for physicians in use of treatment guidelines, training for primary care nurses to function as care managers, and consultation with psychiatrists as support) or to give enhanced care as usual to all eligible patients aged 60 years and older with major depressive disorder. Clinics were chosen randomly for inclusion from all primary care clinics in the district by computer algorithm and then randomly allocated depression care interventions remotely by computer algorithm. Physicians, study personnel, and patients were not masked to clinic assignment. Our primary outcome was difference in Hamilton Depression Rating Scale (HAMD) score using data for clusters at baseline and 3, 6, and 12 month follow-up in a mixed-effects model of the intention-to-treat population. We originally aimed to analyse outcomes at 24 months, however the difference between groups at 12 months was large and funding was insufficient to continue to 24 months, therefore we decided to end the trial at 12 months. This trial is registered with ClinicalTrials.gov, number NCT01287494. Of 34 primary care clinics in Shangcheng district, 16 were randomly chosen. We randomly assigned eight clinics to the DCM intervention (164 patients enrolled) and eight primary care clinics to enhanced care as usual (162 patients). There were no major differences in baseline demographic and clinical variables between the groups of patients for each intervention. Over the 12 months, patients in clinics assigned to DCM had a significantly greater reduction in HAMD score than did those in practices assigned to enhanced care as usual (estimated between group difference -6·5 [95% CI -7·1 to -5·9]; Cohen's d 0·8 [95% CI 0·8-0·9]; p<0·0001). The intercluster correlation for change in HAMD total score was 0·07 (95% CI 0·06-0·08). There were no study-related adverse events in either group. Clinical outcomes of Chinese adults older than 60 years who had major depression were improved when their primary care clinic used DCM. Primary care-based collaborative management of depression is promising to address this pressing public health need in China.

2011-03-01

Following the first International Conference on Inverse Problems - Recent Theoretical Development and Numerical Approaches held at the City University of Hong Kong in 2002, the fifth International Conference was held again at the City University during December 13-17, 2010. This fifth conference was jointly organized by Professor Yiu-Chung Hon (Co-Chair, City University of Hong Kong, HKSAR), Dr Leevan Ling (Co-Chair, Hong Kong Baptist University, HKSAR), Professor Jin Cheng (Fudan University, China), Professor June-Yub Lee (Ewha Womans University, South Korea), Professor Gui-Rong Liu (University of Cincinnati, USA), Professor Jenn-Nan Wang (National Taiwan University, Taiwan), and Professor Masahiro Yamamoto (The University of Tokyo, Japan). It was agreed to alternate holding the conference among the above places (China, Japan, Korea, Taiwan, and Hong Kong) once every two years. The next conference has been scheduled to be held at the Southeast University (Nanjing, China) in 2012. The purpose of this series of conferences is to establish a strong collaborative link among the universities of the Asian-Pacific regions and worldwide leading researchers in inverse problems. The conference addressed both theoretical (mathematics), applied (engineering) and developmental aspects of inverse problems. The conference was intended to nurture Asian-American-European collaborations in the evolving interdisciplinary areas and it was envisioned that the conference would lead to long-term commitments and collaborations among the participating countries and researchers. There was a total of more than 100 participants. A call for the submission of papers was sent out after the conference, and a total of 19 papers were finally accepted for publication in this proceedings. The papers included in the proceedings cover a wide scope, which reflects the current flourishing theoretical and numerical research into inverse problems. Finally, as the co-chairs of the Inverse Problems Conference 2010, we wish to express our cordial thanks to all the keynote, plenary, and invited speakers and members of the Advisory Board. We would like to thank the City University of Hong Kong, the Hong Kong Mathematical Society, the K C Wong Education Foundation, the Lee Hysan Foundation, and the Wei Lun Foundation for their generous financial support. Particularly, we wish to thank Miss Lonn Chan for her excellent administrative work in making all the arrangements for the conference.

Over the period 1995-2012, David Triggle was a frequent visitor to the China Pharmaceutical University in Nanjing, China making many important contributions that enhanced the activities of the Research Division of Pharmacology at the University. In addition to providing collegial advice and facilitating interactions with the international pharmacological community, Professor Triggle's international reputation as a thought leader in the field of ion channel research and drug discovery provided important insights into the potential pathophysiological and therapeutic effects of targeting ion channels. This included the L-type calcium channel and the outward delayed rectified potassium currents of rapid (IKr) and slow (IKs) components in the myocardium. The Nanjing research team had been particularly interested in ion channel dysfunction in the context of cardiac arrhythmias, remodeling and drug discovery. With Professor Triggle's assistance, the relationship between an increase in ICa.L and other biological events including an enhancement of IKr and IKr currents, NADPH oxidase and endothelin receptor activation, down regulation of calcium modulating protein FKBP12.6, sarco/endoplasmic reticulum Ca(2+)ATPse (SERCA2A) and calsequens 2 (CASQ2), calcium leak at the diastole and endoplasmic reticulum stress, were evaluated and are discussed. Additionally, the organization of several international symposia was greatly enhanced by input from Professor Triggle as were the published research manuscripts in international pharmacology journals. During his association with the China Pharmaceutical University, Professor Triggle aided in enhancing the scientific standing of the Pharmacology department and was a highly effective ambassador for international research cooperation.

University of Chinese Academy of Sciences, Beijing 100049, China We report the measurement of magnetic pulses from the negative stepped leaders in positive rocket-triggered lightning flashes with the low-frequency (4 kHz to 420 kHz) magnetic sensor at two different distances (78 m and 970 m, respectively) during the SHantong Artificial Triggered Lightning Experiments (SHATLE) during summer of 2015. Different from the magnetic radiation from positive leaders as observed in the considerably more frequent cases, the impulsive signals from the negative leader sustain for a much longer time interval, while the attenuation of current pulse launched by the stepping of leader is also observed. The general pattern of magnetic pulses observed for the negative stepped leader is different from the positive counterpart. Also, the initial negative leader appears to be brighter than the positive ones, as shown by both high-speed video observation and the magnetic measurement.

Of 15 extended-spectrum beta-lactamase (ESBL)-producing isolates of the family Enterobacteriaceae collected from the First Municipal People's Hospital of Guangzhou, in the southern part of the People's Republic of China, 9 were found to produce CTX-M ESBLs, 3 produced SHV-12, and 3 produced both CTX-M and SHV-12. Eleven isolates produced either TEM-1B or SHV-11, in addition to an ESBL. Nucleotide sequence analysis of the 12 isolates carrying bla(CTX-M) genes revealed that they harbored three different bla(CTX-M) genes, bla(CTX-M-9) (5 isolates), bla(CTX-M-13) (1 isolate), and bla(CTX-M-14) (6 isolates). These genes have 98% nucleotide homology with bla(Toho-2). The bla(CTX-M) genes were carried on plasmids that ranged in size from 35 to 150 kb. Plasmid fingerprints and pulsed-field gel electrophoresis showed the dissemination of the bla(CTX-M) genes through transfer of different antibiotic resistance plasmids to different bacteria, suggesting that these resistance determinants are highly mobile. Insertion sequence ISEcp1, found on the upstream region of these genes, may be involved in the translocation of the bla(CTX-M) genes. This is the first report of the occurrence of SHV-12 and CTX-M ESBLs in China. The presence of strains with these ESBLs shows both the evolution of bla(CTX-M) genes and their dissemination among at least three species of the family Enterobacteriaceae, Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae, isolated within a single hospital. The predominance of CTX-M type enzymes seen in this area of China appears to be similar to that seen in South America but is different from those seen in Europe and North America, suggesting different evolutionary routes and selective pressures. A more comprehensive survey of the ESBL types from China is urgently needed.

With 25% of the global burden, China has the highest incidence of drug-resistant tuberculosis (TB) in the world. However, surveillance data on extensively drug-resistant TB (XDR-TB) from China are scant. To estimate the prevalence of XDR-TB in Zhejiang, Eastern China, 30 of 90 TB treatment centers in Zhejiang were recruited. Patients with suspected TB who reported to the clinics for diagnosis were requested to undergo a smear sputum test. Positive sputum samples were tested for drug susceptibility. Data on anti-TB drug resistance from 1999 to 2008 were also collected to assess drug resistance trends. A total of 931 cases were recruited for drug susceptibility testing (DST). Among these, 23.6% (95% confidence interval [CI], 18.8-24.4) were resistant to any of the following drugs: isoniazid, rifampin, streptomycin, and ethambutol. Multidrug resistant (MDR) strains were identified in 5.1% of all cases (95% CI, 3.61-6.49). Among MDR-TB cases, 6.4% were XDR (95% CI, 1.7-18.6) and 8.9% (95% CI, 7.0-10.8) of all cases were resistant to either isoniazid or rifampin (but not both). Among MDR-TB cases, 23.4% (95% CI, 12.8-38.4) were resistant to either fluoroquinolones or a second-line anti-TB injectable drug, but not both. From 1999 to 2014, the percentage of MDR cases decreased significantly, from 8.6% to 5.1% (p = 0.00). The Global Fund to Fight TB program showed signs of success in Eastern China. However, drug-resistant TB, MDR-TB, and XDR-TB still pose a challenge for TB control in Eastern China. High-quality directly observed treatment, short-course, and universal DST for TB cases to determine appropriate treatment regimens are urgently needed to prevent acquired drug resistance.

Risk behavior often seems 'self-defeating' to the observers. Most people understand the basic health-related knowledge, but some of them still choose to continue risk behaviors, especially for the young. This study aimed to examine time perspective, optimism bias and self control correlated with smoking behavior in Chinese college students. A cross-sectional survey enrolling 3016 university students in Chengdu City, Sichuan Province, China. Influence Factors were identified using multiple logistic regression analyses. Prevalence of current smoking was 20.92% (631 smokers), including 272 daily smokers (9.02%) and 359 non-daily smokers (11.90%). Future-oriented time perspective, general capacity for self-discipline, reliability and ethnicity were protective factors of smoking behavior. Possibility of self-suffering diseases and gender were risk factors of smoking behavior. Smoking in University of Chengdu, China is a severe problem. Results in this research have suggested that irrespective of the smoking level, improving health-related knowledge, time management awareness and self-control ability may contribute to reducing the prevalence of smoking behavior.

In Mainland China, heparin saline solution is commonly used for flushing and locking peripheral intravenous access devices in clinical practice for a long time. We conducted a prospective controlled trial to compare the effectiveness and safety of preservative-free 0.9% sodium chloride solution versus heparin saline solution as flushing and locking solution for peripheral intravenous access devices. Patients with gastroenterological or hepatic diseases were enrolled for this study from August 2011 to October 2011. After non-randomized allocation, preservative-free 0.9% sodium chloride was used as flushing and locking solution in the sodium chloride solution group, while hepatic solution (10 U/mL) was given in the heparin saline solution group. The device related complications and its maintenance duration were compared between two groups. One-way ANOVA, Chi(2), or Mantel-Haenszel test were performed using SPSS 13.0 and RevMan 5.0. Totally, 181 and 178 peripheral intravenous access devices in the sodium chloride solution and heparin saline solution groups were included and analyzed. Results indicated than sodium chloride solution did not increase the risks of occlusion (7.7% vs. 7.9%) and other adverse events of peripheral intravenous access devices (P = 0.163). Sodium chloride solution neither shortened the duration of peripheral intravenous access devices maintenance (3.6 ± 1.1 days vs. 3.7 ± 1.2 days, P = 0.651), nor increased the proportion of abnormal withdrawal (29.3% vs. 31.5%, P = 0.654). Sodium chloride solution is as effective and safe as conventional heparin saline solution for flushing and locking peripheral intravenous access devices, which results from our evidence-based study and should be transferred to other nurses in China. © 2012 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

First results from the International Urban Energy Balance Model Comparison: Model Complexity

NASA Astrophysics Data System (ADS)

Blackett, M.; Grimmond, S.; Best, M.

2009-04-01

A great variety of urban energy balance models has been developed. These vary in complexity from simple schemes that represent the city as a slab, through those which model various facets (i.e. road, walls and roof) to more complex urban forms (including street canyons with intersections) and features (such as vegetation cover and anthropogenic heat fluxes). Some schemes also incorporate detailed representations of momentum and energy fluxes distributed throughout various layers of the urban canopy layer. The models each differ in the parameters they require to describe the site and the in demands they make on computational processing power. Many of these models have been evaluated using observational datasets but to date, no controlled comparisons have been conducted. Urban surface energy balance models provide a means to predict the energy exchange processes which influence factors such as urban temperature, humidity, atmospheric stability and winds. These all need to be modelled accurately to capture features such as the urban heat island effect and to provide key information for dispersion and air quality modelling. A comparison of the various models available will assist in improving current and future models and will assist in formulating research priorities for future observational campaigns within urban areas. In this presentation we will summarise the initial results of this international urban energy balance model comparison. In particular, the relative performance of the models involved will be compared based on their degree of complexity. These results will inform us on ways in which we can improve the modelling of air quality within, and climate impacts of, global megacities. The methodology employed in conducting this comparison followed that used in PILPS (the Project for Intercomparison of Land-Surface Parameterization Schemes) which is also endorsed by the GEWEX Global Land Atmosphere System Study (GLASS) panel. In all cases, models were run offline to ensure no feedback to larger scale conditions within the modelling domain. Initially, participants were issued with just forcing data from an unknown urban site (termed "Alpha"); in subsequent stages, further details of the site were provided. Results from each stage, for each participating model, were then compared using a variety of statistical and graphical techniques. * The EGU2009-5713 Team: C.S.B. Grimmond1, M. Blackett1, M.

Pervious to simulations, the changes of net primary productivity (NPP) in the InTEC model was calibrated using field measured NPP and ages of forests. Both forest inventory and model simulations indicated that carbon sequestration by forests in China increased significantly in recent decades. The forest inventory based estimates indicated that biomass carbon sinks of forest stands were 86.0 Tg C yr-1 and 174.0 Tg C yr-1 in China and 132.5 Tg C yr-1and 147.0 Tg C yr-1 in the continental U.S. during the periods from 1989 to 2008 and from 1999 to 2008, respectively. The InTEC model simulations indicated that the total carbon sinks of forests were 170.4 Tg C yr-1, 200.2 Tg C yr-1, 217.7 Tg C yr-1 in China and 225.9 Tg C yr-1, 222.7 Tg C yr-1, and 230.5 Tg C yr-1 in the continental U.S. during the periods from 1981 to 2010, from 1991 to 2010, and from 2001 to 2010, respectively. Forest carbon sink density was higher in China than that in the continental U.S., mainly due to a larger fraction of young forests in China. Total carbon sequestration by forests in China was close to that in the continental U.S. during the recent decade.

The recent upsurge of syphilis infections among men who have sex with men (MSM) is one of the major challenges facing China. However, the overall burden is still not clear. This study aims to summarize the incidence of syphilis among MSM in China by using meta-analysis. We comprehensively searched PubMed-MEDLINE, China National Knowledge Infrastructure and Chinese Wanfang databases. Articles published between December 2009 and March 2015 that met the inclusion criteria were considerably involved in this meta-analysis. Two reviewers performed a quality assessment of the studies and extracted data for estimating the overall syphilis incidence. STATA 12.0 was used to summarize the overall incidence of syphilis. In all, 14 studies from 13 papers were included in this study. Follow-up duration of these studies ranged from six to 36 months, while drop-out rates ranged from 11.9% to 83.6%. The individual incidence rates of the included studies varied from 3.1/100 person-years (95% CI, 0.8-5.3/100 person-years) to 38.5/100 person-years (95% CI, 28.9-48.1/100 person-years), with a pooled incidence of 9.6/100 person-years (95% CI, 7.0-12.2/100 person-years). The subgroup meta-analysis revealed that incidence estimates were 38.5/100 person-years (95% CI, 28.9-48.1/100 person-years), 12.1/100 person-years (95% CI, 7.0-17.2/100 person-years), 11.2/100 person-years (95% CI, 0.7-23.1/100 person-years), 8.9/100 person-years (95% CI, 6.5-11.2/100 person-years), 5.7/100 person-years (95% CI, 3.4-8.0/100 person-years) and 3.1/100 person-years (95% CI, 0.8-5.3/100 person-years) in Northeast, North, Southwest, East, South and Northwest China, respectively. Syphilis incidence among Chinese MSM is high, and this may increase the spread of other sexually transmitted infections, including human immunodeficiency virus. It is essential to integrate syphilis control programs with HIV control programs. This can be achieved by establishing public health response systems to monitor and control the epidemic of syphilis and HIV together in China.

Background Functional gastrointestinal disorders, including functional dyspepsia, irritable bowel syndrome and functional constipation are very common worldwide. Objective This research aims to estimate the prevalence and associated factors involved in functional gastrointestinal disorders in Chinese college and university students using the Rome III criteria. Methods A total of 5000 students from Shandong University in China were asked in January-May 2012 to complete questionnaires, including the Rome III questionnaire, hospital anxiety and depression scale, and negative life events scale. Results Based on the 4638 students who completed the questionnaire, the prevalence of functional dyspepsia, irritable bowel syndrome and functional constipation in college and university students of North China worked out to be 9.25%, 8.34% and 5.45% respectively. They were more frequent in female students. The factors of anxiety (OR 1.07; 95% CI 0.99 to 1.16, P = 0.002<0.05) and depression (OR 0.55; 95% CI 0.15 to 1.05, P = 0.045<0.05) indicated a high risk of causing irritable bowel syndrome. Conclusion Functional dyspepsia, irritable bowel syndrome and functional constipation were common in college and university students of North China. Psychological disorders such as anxiety and depression provide significant risk factors for irritable bowel syndrome patients. PMID:23349820

The interaction between proteins and lipids is one of the basic problems of modern biochemistry and biophysics. The purpose of this study is to compare the penetration degree of lysozyme into 1,2-diapalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1,2-dipalmitoyl-sn-glycero-3-phosphoethano-lamine (DPPE) by analyzing the data of surface pressure-area (π-A) isotherms and surface pressure-time (π-T) curves. Lysozyme can penetrate into both DPPC and DPPE monolayers because of the increase of surface pressure at an initial pressure of 15 mN/m. However, the changes of DPPE are larger than DPPC, indicating stronger interaction of lysozyme with DPPE than DPPC. The reason may be due to the different head groups and phase state of DPPC and DPPE monolayers at the surface pressure of 15 mN/m. Atomic force microscopy reveals that lysozyme was absorbed by DPPC and DPPE monolayers, which leads to self-aggregation and self-assembly, forming irregular multimers and conical multimeric. Through analysis, we think that the process of polymer formation is similar to the aggregation mechanism of amyloid fibers.

Zhou, Ping; Tijssen, Robert; Leydesdorff, Loet

2016-01-01

In this study, university-industry collaborations in China and the USA are analyzed in terms of co-authored publications indexed in the Web of Science (WoS). Results show a wide gap between China and the USA: Chinese universities are much less active in collaborations with industry in terms of either publication productivity or collaboration intensity. In selecting local and foreign industrial partners, however, more variation exists among Chinese universities than among US universities. The US system is domestically oriented more than that of China. In the USA, the intensity of university-industry collaboration is determined by research quality, whereas in China this is not the case. In both China and the USA, distance is not critical for the establishment of domestic university-industry collaboration. A high correlation is found between productivity indicators including total publications and university-industry co-authored publications. However, the productivity indicators are less correlated with the intensity of university-industry collaboration. Large research universities with strong ties to domestic industry play critical roles in both national publication systems.

China's emergency management of severe acute respiratory syndrome (SARS) was heavily criticized, whereas the H7N9 response was praised by the international community. Aims The aims of this study were to examine and compare the strengths and weaknesses of risk communication conducted in response to SARS and H7N9 and their associated social impacts on affected communities in China. A qualitative comparative case study approach was employed in the present study, using a set of 8 risk communication principles selected from international literature to suit the Chinese context for the comparative analysis of emergency responses of SARS and H7N9. The study found significant differences in the risk communication conducted in the 2 cases. The SARS outbreak fully exposed China's lack of experience in public health risk communication. By contrast, the Chinese government's risk communication strategies had improved significantly during the H7N9 outbreak. Discussion Trust is the basis for communication. Maintaining an open and honest attitude and actively engaging stakeholders to address their risk information needs will serve to build trust and facilitate multi-sector collaborations in dealing with a public health crisis. From SARS to H7N9, risk communication practices in China greatly improved, which, in turn, lessened adverse social impacts and improved outcomes in emergency management of public health crises.

Obesity has become an epidemic in developing countries including China. The use of bariatric surgery to treat obesity has grown in popularity worldwide, but it is still a new concept in China. This study aims to investigate the trends in bariatric surgery in China. An electronic search of the MEDLINE, EMBASE, and Chinese National Knowledge Infrastructure was conducted to select studies for this survey. A total of 7779 bariatric procedures were reported from 2001 to 2015, most of which (89.2 %) were performed in the most recent 5 years. Further, 70.9 % of all procedures were performed to treat obesity and related comorbidities, defined as metabolic surgery. The data showed 89.4 % of all operations were performed laparoscopically. The absolute number of bariatric surgeries increased 148.7 times in the last 5 years compared to the 2001-2005 period. The percentage of laparoscopic Roux-en-Y gastric bypasses performed increased from 0 to 62.2 %, and the percentage of laparoscopic sleeve gastrectomies from 0 to 12.7 %. The percentage of laparoscopic adjustable gastric bands increased dramatically from 0 to 73.3 % in the 2006-2010 period, but it dropped quickly to 12.9 % in the 2011-2015 period. Most operations (66.7 %) were conducted in the East area, which is the most developed economic region in China. There was limited surgical innovation or original research reported in China. Bariatric surgery is still at an early stage in China, but is now experiencing an explosive growth. A national registry system needs to be established to record and provide precise data.

A comprehensive understanding of the contextual factors that are linked to student engagement requires research that includes cross-cultural perspectives. This study investigated how student engagement in school is associated with grade, gender, and contextual factors across 12 countries. It also investigated whether these associations vary across countries with different levels of individualism and socio-economic development. The participants were 3,420 7th, 8th, and 9th grade students from Austria, Canada, China, Cyprus, Estonia, Greece, Malta, Portugal, Romania, South Korea, the United Kingdom, and the United States. The participants completed a questionnaire to report their engagement in school, the instructional practices they experienced, and the support they received from teachers, peers, and parents. Hierarchical linear modelling was used to examine the effects at both student and country levels. The results across countries revealed a decline in student engagement from Grade 7 to Grade 9, with girls reporting higher engagement than boys. These trends did not vary across the 12 countries according to the Human Development Index and Hofstede's Individualism Index. Most of the contextual factors (instructional practices, teacher support, and parent support) were positively associated with student engagement. With the exception that parent support had a stronger association with student engagement in countries with higher collectivism, most of the associations between the contextual factors and student engagement did not vary across countries. The results indicate both cultural universality and specificity regarding contextual factors associated with student engagement in school. They illustrate the advantages of integrating etic and emic approaches in cross-cultural investigations. © 2015 The British Psychological Society.

China is the most populated country and has one of the highest prevalences of oral clefting. The present study reports the epidemiology and surgical procedures performed on the largest reported cohort of individuals with clefting in China. A retrospective review of patients who received cleft repair through Smile Train in China from 2000 to 2011 was conducted. Data on demographics, cleft characteristics, associated malformations, pregnancy and family history, and surgical technique were analyzed using SPSS (IBM, Chicago, Ill.). A total of 205,679 patients underwent 209,169 cleft procedures. Cleft lip and palate (42.7%) was most common followed by isolated cleft palate (32.4%) and isolated cleft lip (24.9%). Males accounted for 63.5% of cases. The average age at initial surgery was 6.12 years. By 2011, this decreased to 1.8 years of age for lip repair and to 5.9 years of age for palate repair. The preferred techniques were rotation-advancement (55%) for unilateral lip repair and Von-Langenbeck (38%) and pushback (39%) for palate repair. The percentages of cases with associated anomalies and surgical complications were 12.8% and 0.36%, respectively. This study provides insight into cleft care in China as it reports the largest cohort of cleft patients treated by surgeons to date. Our results generally follow trends previously reported in China and developed countries. The male:female ratio for cleft palate patients was higher than expected. The average age at primary repair is higher than recommended, but seems to be decreasing.

Health care workers (HCWs) seek, treat, and care for patients living with HIV/AIDS on a daily basis and thus face a significant risk to work-related infections. To assess the knowledge, attitude, and practices regarding occupational HIV exposure and protection among HCWs in low HIV prevalence areas of rural China. A cross-sectional questionnaire survey was carried out among all medical units in Pucheng County, Shaanxi, China. Response rate of this study was 94%. The average overall knowledge score of HCWs was 10.9 of 21.0. Deficiencies in general, transmission, exposure, and protection knowledge were identified among HCWs at all levels. A high rate of occupational exposure (85%) and lack of universal precautions practice behavior were recorded. Significant predictors of universal precautions practice behavior were female sex, prior training, and greater knowledge about HIV/AIDS. Health care workers at various levels have inadequate knowledge on HIV/AIDS and do not practice universal precautions. Nurses and medical technicians at the county level faced more occupation risk than other HCWs. The key of AIDS training for different levels of HCWs should be distinguished. © The Author(s) 2014.

The origin of these structure is presently unknown. Non-linear interactions of the solar wind MHD turbulence can spontaneously generate these structures. On the other hand, there are proposals that these structures may represent relic structures having solar origins. Using a technique developed in [1], we examine current sheets in the solar wind from multiple spacecraft. We identify the "single-peak" and "double-peak" events in the solar wind and discuss possible scenarios for these events and its implication of the origin of the current sheets.

Medico-legal death investigation in China has a long history that can be traced back to the Chhin era in the third century BC. We conducted a national study on the current medico-legal death investigation system in China. Our study showed that, at present, medico-legal death investigations in China are conducted by c. 12,000 forensic medical experts mainly within five relatively independent agencies: the police organizations, the prosecutors' offices, the departments/divisions of forensic medicine/science in medical colleges and universities, the Institute of Forensic Science in the Ministry of Justice, and the government or private forensic societies. Owing to China's large population and area, the medico-legal death investigation is largely based on the administrative divisions. There is a wide variation in the scope, extent, and quality of investigations among the agencies and at the different levels of county/district, municipal, and provincial governments. This article gives a general overview of medicolegal death investigation in modern China. © 2011 American Academy of Forensic Sciences.

Increasing dairy consumption in China has been accompanied by rising incidence of milk allergy. Here we analyzed profiles of specific immunoglobulin E (sIgE) against cow's milk proteins, and assessed their value for milk allergy diagnosis among infants and young children from northern China. Sera collected from 48 patients with milk allergy and 27 negative control subjects was analyzed by enzyme-linked immunosorbent assay to measure sIgE to α-lactalbumin (Bos d 4), β-lactoglobulin (Bos d 5), α-casein (Bos d 9), β-casein (Bos d 11), and κ-casein (Bos d 12). Among milk-allergic individuals, most were sensitized to at least one milk protein; about half were sensitized to Bos d 5, Bos d 9, Bos d 11 and Bos d 12, respectively, while few had positive serum sIgE against Bos d 4. Bos d 12 sIgE had the largest area under curve (AUC) (0.878; 95% CI, 0.800-0.957) and thus showed the best diagnostic performance in discriminating between milk-allergic and non-milk allergic patients, with a sensitivity of 92.6% and specificity of 72.9% using a statistically optimal cut-off value (OD 450nm , 0.191). The combinations of Bos d 5 + Bos d 12 showed an AUC of 0.926, which was larger than for any individual components. Our results revealed inter-individual variation in the sensitization to different milk allergen component. Bos d 12 sIgE showed best performance in diagnosing milk allergy. Milk allergy diagnostic accuracy was further improved using combinations of milk allergen components by application of ROC curves based on logistic regression. Copyright © 2018 Elsevier B.V.

Health risks stemming from betel-quid (BQ) chewing are frequently overlooked by people. Updated epidemiological data on the increased BQ use among Asian populations using comparable data collection methods have not been widely available. To investigate the prevalence, patterns of practice and associated types of oral preneoplastic disorders, an intercountry Asian Betel-quid Consortium study (the ABC study) was conducted for Taiwan, Mainland China, Malaysia, Indonesia, Nepal and Sri Lanka. A random sample of 8,922 subjects was recruited, and the data were analyzed using survey-data modules adjusted for the complex survey design. Chewing rates among men (10.7-43.6%) were significantly higher than women (1.8-34.9%) in Taiwan, Mainland China, Nepal and Sri Lanka, while women's rates (29.5-46.8%) were higher than that for men (9.8-12.0%) in Malaysia and Indonesia. An emerging, higher proportion of new-users were identified for Hunan in Mainland China (11.1-24.7%), where Hunan chewers have the unique practice of using the dried husk of areca fruit rather than the solid nut universally used by others. Men in the Eastern and South Asian study communities were deemed likely to combine chewing with smoking and drinking (5.6-13.6%). Indonesian women who chewed BQ exhibited the highest prevalence of oral lichen planus, oral submucous fibrosis and oral leukoplakia (9.1-17.3%). Lower schooling, alcohol drinking and tobacco smoking were identified as being associated with BQ chewing. In conclusion, the ABC study reveals the significant cultural and demographic differences contributing to practice patterns of BQ usage and the great health risks that such practices pose in the Asian region.

Methadone maintenance treatment (MMT) has been implemented in China since 2004 and has expanded into a nationwide programme. This study aims to evaluate changes in social functioning, family relations and drug-related criminal behaviour among MMT clients in China. Systematic review and meta-analysis. Both English and Chinese literature databases, including PubMed, Chongqing VIP Chinese Science and Technology Journals Database (CQVIP), China National Knowledge Infrastructure (CNKI) and Wanfang Data, were comprehensively searched over the period 2004-2014 for studied indicators. Study selection, quality assessment and data extraction were conducted according to the PRISMA (preferred reporting items for systematic reviews and meta-analyses) Statement. Meta-analyses were conducted using Comprehensive Meta-Analysis Biostat software. Thirty-eight articles were included in this review (1 in English and 37 in Chinese). The self-reported arrest rate decreased from 13.1% (95% CI 9.1% to 18.5%) at baseline to 3.4% (95% CI 1.5% to 7.7%) and 4.3% (95% CI 1.6% to 11.4%) after 6 and 12 months of MMT intervention, respectively. The rate of drug selling decreased from 7.6% (95% CI 3.8% to 14.8%) at baseline to 1.9% (95% CI 0.6% to 6.2%) and 3.0% (95% CI 1.0% to 8.9%) after 6 and 12 months of intervention, respectively. Similarly, the rates of selling sex for drugs and drug-related crime decreased from 5.3% (95% CI 2.4% to 11.1%) and 9.9% (95% CI 6.8% to 14.2%) at baseline to 1.1% (95% CI 0.5% to 2.3%) and 3.4% (95% CI 2.5% to 4.5%) at 6 months, then to 0.8% (95% CI 0.3% to 1.9%) and 3.4% (95% CI 0.8% to 13.1%) at 12 months after treatment initiation, respectively. In contrast, the rate of employment of clients and the proportion of clients having a good relationship with their family increased substantially from 26.4% (95% CI 22.9% to 30.1%) and 37.9% (95% CI 32.0% to 44.2%) to 41.6% (95% CI 36.6% to 48.0%) and 59.6% (95% CI 48.1% to 70.2%) at 6 months, then to 59.8% (95% CI 52.4% to 66.8%) and 75.0% (95% CI 69.0% to 80.2%) at 12 months after treatment initiation, respectively. MMT has significantly reduced criminal activity, and improved employment rate and social well-being, of clients of the MMT programme. MMT is an effective measure to help drug users to resume societal and familial functions in China. Published by the BMJ Publishing Group Limited.

This study examined the impact of rubella immunization, implemented in Hong Kong in phases since 1978, on antenatal rubella serological status in Chinese women. In a retrospective cohort study, the incidence of antenatal rubella seronegative status in our parturients managed from 1998 to 2013 was analyzed by their year-of-birth as follows: <1965 (no childhood immunization), 1965-1982 (single dose at Primary 6), and ≥1983 (two doses at age 12 months and 12 years), adjusting for other factors including age, parity, body mass index, place-of-birth status and hepatitis B surface antigen (HBsAg) status. Rubella seronegativity decreased from 12.9%, 10.5%, to 9.8% respectively, and correlated inversely (P<0.001) with year-of-birth cohorts. Despite similar demographic profiles, this correlation was found only in Hong-Kong-born women (from 12.6%, 7.5% to 6.5% respectively), who also had significant lower incidences of rubella seronegativity (OR 0.73, 0.31 and 0.29 respectively) and HBsAg seropositivity (OR 1.09, 0.63 and 0.48 respectively) than China-born women. On regression analysis, rubella seronegativity was actually significantly increased following the implementation of immunization (aOR 1.20) while it was the reverse for non-residents (aOR 0.61). Although rubella seronegativity decreased with immunization, the effect was less than expected when adjusted for other risk factors. Copyright © 2015 Elsevier Ltd. All rights reserved.

The prevalence of childhood overweight and obesity in developed countries appears to be plateauing. The purpose of this study was to provide the most recent data on the prevalence and trends in overweight and obesity among Chinese children and adolescents from 2011 to 2015. We used data collected in the China Health and Nutrition Survey (CHNS) and China Nutritional Transition Cohort Study (CNTCS). We used two waves of the survey in 12 provinces conducted in 2011 (aged 7-18 years; n = 1458) and 2015 (aged 7-18 years; n = 1084) to perform a trend analysis. We used data collected in 15 provinces (aged 7-18 years; n = 1617) to estimate the prevalence of overweight and obesity among Chinese children and adolescents in 2015. In 2015, based on the Working Group for Obesity in China (WGOC) criteria, the prevalence of overweight and obesity were 14.0% (95% CI, 11.6-16.3) and 10.5% (95% CI, 8.4-12.6) in boys, and 9.7% (95% CI, 7.7-11.8) and 7.1% (95% CI, 5.2-8.9) in girls, respectively. The increase in BMI z-scores from 2011 to 2015 was statistically significant among adolescents (p = 0.0083), but not among children. No significant changes were observed in prevalence of overweight and obesity between 2011 and 2015, excepting adolescents aged 12-18 years (p = 0.0086). Since 2011, overweight has remained stable, and obesity has stabilized in children, though not in adolescents. Although levels of childhood overweight and obesity in China are not high compared to other developed countries, they remain concerning enough that effective policies and interventions need to be sustained and intensified for lowering rates of childhood overweight and obesity.

Background: China is the most populated country and has one of the highest prevalences of oral clefting. The present study reports the epidemiology and surgical procedures performed on the largest reported cohort of individuals with clefting in China. Methods: A retrospective review of patients who received cleft repair through Smile Train in China from 2000 to 2011 was conducted. Data on demographics, cleft characteristics, associated malformations, pregnancy and family history, and surgical technique were analyzed using SPSS (IBM, Chicago, Ill.). Results: A total of 205,679 patients underwent 209,169 cleft procedures. Cleft lip and palate (42.7%) was most common followed by isolated cleft palate (32.4%) and isolated cleft lip (24.9%). Males accounted for 63.5% of cases. The average age at initial surgery was 6.12 years. By 2011, this decreased to 1.8 years of age for lip repair and to 5.9 years of age for palate repair. The preferred techniques were rotation-advancement (55%) for unilateral lip repair and Von-Langenbeck (38%) and pushback (39%) for palate repair. The percentages of cases with associated anomalies and surgical complications were 12.8% and 0.36%, respectively. Conclusions: This study provides insight into cleft care in China as it reports the largest cohort of cleft patients treated by surgeons to date. Our results generally follow trends previously reported in China and developed countries. The male:female ratio for cleft palate patients was higher than expected. The average age at primary repair is higher than recommended, but seems to be decreasing. PMID:25426353

To retrospectively analyse the medical imaging examination results of the injuries and illnesses during the 2008 Olympic Games and 2013 China National Games in Shenyang Divison. Collected and analyzed the health information and medical imaging examination results from Shengjing Hospital of China Medical University during the two games. There was 9 cases of sports injuries in the 2008 Olympic Games, mainly for knee, ankle ligament injury and muscle sprain, 36 cases of sports injuries in the 2013 China National Games, mainly for head traumas (9 cases), knee injuries (7 cases), ankle injuries (7 cases), shoulder injures (4 cases). Competitions of high risk of being injured were wrestling (10 cases), track and field (8 cases), American football (6 cases). The most common cause of illness were respiratory system (60 cases) and the digestive system (27 cases) in the total 233 cases illnesses in the China National Games. Different sports have different characteristic, regularity and mechanism of injury. Medical imaging examination has important value in the diagnosis of injury during large games. The respiratory system and digestive system are the most common illnesses and affect the athletes training and competition as important as injuries. So illness is the focus on the medical care assurance of the large games.

On 23 May 2012, a university in Jiangxi, China reported a gastroenteritis outbreak. We investigated the outbreak to identify the agent, source and mode of transmission and to recommend control measures. A case was defined as any person from the university with onset of diarrhoea (≥ 3 times/24h) from 1 to 31 May 2012. Active case finding was conducted by reviewing university hospital and drug-store records and interviewing students, workers and teachers. We then conducted a case-control study in which we compared food, water and environmental exposure history. Water samples were collected and tested. We identified 417 cases - an attack rate (AR) of 4.7% (417/8781) for the university. There were 416 student cases (AR = 5.7%) distributed across all 11 colleges, five of which were more heavily affected (AR range = 5.9-14%). In the case-control study, cases had higher odds of having drunk bottled water (odds ratio [OR] = 4.1; 95% confidence interval [CI] = 1.7-9.9), and there was a dose-response relationship (χ(2)trend = 4.6, P < 0.05). Drinking boiled bottled water was inversely associated with being a case (OR = 0.22, 95% CI = 0.07-0.71). Eating in any of the three university canteens or drinking-water from the city water supply was not associated with being a case. Pathogenic Escherichia coli was isolated from two unopened bottled water specimens and from four student cases. This gastroenteritis outbreak was most likely caused by contaminated bottled water. The company in question has been shut down and no further cases have been reported. Increased regulation of bottled water plants and better coordination between different investigators for future outbreaks is recommended.

China's increasing energy consumption and coal-dominant energy structure have contributed not only to severe environmental pollution, but also to global climate change. This article begins with a brief review of China's primary energy use and associated environmental problems and health risks. To analyze the potential of China's transition to low-carbon development, three scenarios are constructed to simulate energy demand and CO₂ emission trends in China up to 2050 by using the Long-range Energy Alternatives Planning System (LEAP) model. Simulation results show that with the assumption of an average annual Gross Domestic Product (GDP) growth rate of 6.45%, total primary energy demand is expected to increase by 63.4%, 48.8% and 12.2% under the Business as Usual (BaU), Carbon Reduction (CR) and Integrated Low Carbon Economy (ILCE) scenarios in 2050 from the 2009 levels. Total energy-related CO₂ emissions will increase from 6.7 billiontons in 2009 to 9.5, 11, 11.6 and 11.2 billiontons; 8.2, 9.2, 9.6 and 9 billiontons; 7.1, 7.4, 7.2 and 6.4 billiontons in 2020, 2030, 2040 and 2050 under the BaU, CR and ILCE scenarios, respectively. Total CO₂ emission will drop by 19.6% and 42.9% under the CR and ILCE scenarios in 2050, compared with the BaU scenario. To realize a substantial cut in energy consumption and carbon emissions, China needs to make a long-term low-carbon development strategy targeting further improvement of energy efficiency, optimization of energy structure, deployment of clean coal technology and use of market-based economic instruments like energy/carbon taxation.

Human infection with the emerging avian influenza A(H7N9) virus in China in 2013 has raised global concerns. We conducted a retrospective descriptive study of 27 confirmed human influenza A(H7N9) cases in Jiangsu Province, to elaborate poultry-related exposures and to provide a more precise estimate of the incubation periods of the illness. The median incubation period was 6 days (range 2-10 days) in cases with single known exposure and was 7·5 days (range 6·5-12·5 days) in cases with exposures on multiple days, difference between the two groups was not significant (Z = -1·895, P = 0·058). The overall median incubation period for all patients was estimated to be 7·5 days (range 2-12·5 days). Our findings further highlight the necessity for public health authorities to extend the period of medical surveillance from 7 days to 10 days.

To detect the expression of Pokemon in endometrial carcinoma (EC), to provide preliminary theoretical basis for clarifying pathogenesis and searching for effective targets. Ninety-eight cases of endometrial tissue paraffin specimens form July 2012 to July 2014 in West China Second University Hospital, Sichuan University, were collected, including: EC group, consisting of adenocarcinoma 23 cases, adenosquamous 12 cases, serous 3 cases, mucinous 11 cases and clear cell 9 cases, and control group, consisting of atypical hyperplasia endometrium 20 cases and normal endometrium 20 cases (secretory 10 cases, hyperplasia 10 cases). Immunohistochemistry was used to detect the expression of Pokemonin each section, analyzing the correlation of Pokemon expression with clinicopathologic characteristics and p53 expression. The positive rate of Pokemon in normal endometrium was 25% (5/20), significantly lower than that in atypical hyperplasia endometrium (60.0%, 12/20) and EC (93.1%, 54/58) (P < 0.05); the rate in type II was 97. 12% (34/35), significantly higher than that in type I (86.96%, 20/23) (P = 0.018). The positive rate of Pokemon in III-IV stage, type II and Ki-67 ≥ 50 EC tissue was much higher (P = 0.012, 0.023, 0.029). In type II EC tissue, the correlation index between Pokemon and p53 is 0.669 (P = 0.000). The over expression of Pokemon upregulates the expression of mutant p53, which may be one of the carcinogenesis modes in type II EC.

Because of the rapid change in economic development and lifestyle in China, and the ageing population, concerns have grown that chronic obstructive pulmonary disease (COPD) could become epidemic. An up-to-date nationwide estimation of COPD prevalence in China is needed. We did a cross-sectional survey of a nationally representative sample of individuals from mainland China aged 40 years or older. The primary outcome was COPD, defined according to the 2017 Global Initiative for Chronic Obstructive Lung Disease (GOLD) lung function criteria. Between Dec 29, 2014, and Dec 31, 2015, 66 752 adults were recruited to the study population. The estimated standardised prevalence of COPD was 13·6% (95% CI 12·0-15·2). The prevalence of COPD differed significantly between men and women (19·0%, 95% CI 16·9-21·2 vs 8·1%, 6·8-9·3; p<0·0001), mainly because of a significant difference in smoking status between men and women (current smokers 58·2% vs 4·0%). The prevalence of COPD differed by geographic region, with the highest prevalence in southwest China (20·2%, 95% CI 14·7-25·8) and the lowest in central China (10·2%, 8·2-12·2). Among adults with COPD, 56·4% (95% CI 53·7-59·2) had mild disease (GOLD stage I), 36·3% (34·3-38·3) had moderate disease (GOLD stage II), 6·5% (5·5-7·4) had severe disease (GOLD stage III), and 0·9% (0·6-1·1) had very severe disease (GOLD stage IV). In a large, nationally representative sample of adults aged 40 years or older, the estimated overall prevalence of COPD in China in 2014-15 was 13·6%, indicating that this disease has become a major public-health problem. Strategies aimed at prevention and treatment of COPD are needed urgently.

Chinese social media reaction to the MERS-CoV and avian influenza A(H7N9) outbreaks

PubMed Central

2013-01-01

Background As internet and social media use have skyrocketed, epidemiologists have begun to use online data such as Google query data and Twitter trends to track the activity levels of influenza and other infectious diseases. In China, Weibo is an extremely popular microblogging site that is equivalent to Twitter. Capitalizing on the wealth of public opinion data contained in posts on Weibo, this study used Weibo as a measure of the Chinese people’s reactions to two different outbreaks: the 2012 Middle East Respiratory Syndrome Coronavirus (MERS-CoV) outbreak, and the 2013 outbreak of human infection of avian influenza A(H7N9) in China. Methods Keyword searches were performed in Weibo data collected by The University of Hong Kong’s Weiboscope project. Baseline values were determined for each keyword and reaction values per million posts in the days after outbreak information was released to the public. Results The results show that the Chinese people reacted significantly to both outbreaks online, where their social media reaction was two orders of magnitude stronger to the H7N9 influenza outbreak that happened in China than the MERS-CoV outbreak that was far away from China. Conclusions These results demonstrate that social media could be a useful measure of public awareness and reaction to disease outbreak information released by health authorities. PMID:24359669

Realistic modeling of seismic input for megacities and large urban areas

The project addressed the problem of pre-disaster orientation: hazard prediction, risk assessment, and hazard mapping, in connection with seismic activity and man-induced vibrations. The definition of realistic seismic input has been obtained from the computation of a wide set of time histories and spectral information, corresponding to possible seismotectonic scenarios for different source and structural models. The innovative modeling technique, that constitutes the common tool to the entire project, takes into account source, propagation and local site effects. This is done using first principles of physics about wave generation and propagation in complex media, and does not require to resort to convolutive approaches, that have been proven to be quite unreliable, mainly when dealing with complex geological structures, the most interesting from the practical point of view. In fact, several techniques that have been proposed to empirically estimate the site effects using observations convolved with theoretically computed signals corresponding to simplified models, supply reliable information about the site response to non-interfering seismic phases. They are not adequate in most of the real cases, when the seismic sequel is formed by several interfering waves. The availability of realistic numerical simulations enables us to reliably estimate the amplification effects even in complex geological structures, exploiting the available geotechnical, lithological, geophysical parameters, topography of the medium, tectonic, historical, palaeoseismological data, and seismotectonic models. The realistic modeling of the ground motion is a very important base of knowledge for the preparation of groundshaking scenarios that represent a valid and economic tool for the seismic microzonation. This knowledge can be very fruitfully used by civil engineers in the design of new seismo-resistant constructions and in the reinforcement of the existing built environment, and, therefore, supply a particularly powerful tool for the prevention aspects of Civil Defense.

Scarlet fever is one of a variety of diseases caused by group A Streptococcus (GAS). During 2011, a scarlet fever epidemic characterized by peak monthly incidence rates 2.9-6.7 times higher than those in 2006-2010 occurred in Beijing, China. During the epidemic, hospital-based enhanced surveillance for scarlet fever and pharyngitis was conducted to determine characteristics of circulating GAS strains. The surveillance identified 3,359 clinical cases of scarlet fever or pharyngitis. GAS was isolated from 647 of the patients; 76.4% of the strains were type emm12, and 17.1% were emm1. Almost all isolates harbored superantigens speC and ssa. All isolates were susceptible to penicillin, and resistance rates were 96.1% to erythromycin, 93.7% to tetracycline, and 79.4% to clindamycin. Because emm12 type GAS is not the predominant type in other countries, wider surveillance for the possible spread of emm12 type GAS from China to other countries is warranted.

Abstract The aim of this study was to investigate whether depressive symptoms are associated with suicidal ideation among university students in China. Five Chinese and English electronic databases (EBSCO, PubMed, Chinese Web of Knowledge, Wanfang, and Weipu) were searched to identify relevant studies. Cross-sectional studies published from 2000 to 2016 reporting about the association between depressive symptoms and suicidal ideation among university students in China were used for meta-analysis to approximate the overall association between depression and suicidal ideation among university students in mainland China. StatsDirect 3 was used for meta-analysis of included literatures. Of 513 initially identified references, 44 studies were selected, including 88,431 participants with depressive symptoms. The combined odd ratio of the relationship was 2.174 (95% confidence interval: 2.027–2.333; P < 0.0001). There exists a moderate association between depressive symptoms and suicidal ideation among university students in China, and depressive symptoms contribute to the development of suicidal ideation. In particular, university students from western regions of China, from nonmedical background, should be provided more psychological and clinical assistance. PMID:28353586

China has seen rapid increase in obesity and hypertension prevalence and fast food consumption over the past decade. We examined status and risk factors for Western- and Chinese fast food consumption and their associations with health outcomes in Chinese children, and examined how maternal factors were associated with child health outcomes. Data of 1626 students aged 7-16 (11.6 ± 2.0) years and their parents in four mega-cities across China (Beijing, Shanghai, Nanjing, and Xi'an) were collected in the 2015 baseline survey of the Childhood Obesity Study in China Mega-cities. Weight, height, waist circumference, and blood pressure were measured. Food intake was assessed using questionnaire. Mixed models were used to examine the associations. Among the children, 11.1% were obese, 19.7% were centrally obese, and 9.0% had hypertension. Obesity prevalence was much higher in boys than in girls (15.2% vs. 6.9% and 27.4% vs. 11.7%, respectively, both P < 0.001). About half (51.9% and 43.6%) of children consumed Western and Chinese fast food, respectively, over the past 3 months. Compared to those with college or above maternal education level, those with elementary school or below maternal education level were 49% more likely to consume Western fast food (odds ratio [OR] and 95% confidence interval [CI]: 1.49 [1.10-2.03]). Chinese fast food consumption rate increased by 12% with each year of increase in child's age (OR and 95% CI: 1.12 [1.02-1.23]). No significant associations between fast food consumption and health outcomes were detected. Adjusting for Western fast food consumption, children with lower maternal education were 71% and 43% more likely to have obesity and central obesity (ORs and 95% CIs: 1.71 [1.12-2.61] and 1.43 [1.00-2.03], respectively), and maternal body mass index was positively associated with child obesity, central obesity, and hypertension (ORs and 95% CIs: 1.11 [1.06-1.17], 1.12 [1.07-1.17], and 1.09 [1.03-1.15], respectively). Results were similar when Chinese fast food consumption was adjusted for. The prevalence of fast food consumption, obesity and hypertension is high among children in major cities in China. Maternal factors affect child outcomes.

Coronary artery disease is prevalent in China, with concomitant increases in the volume of coronary artery bypass grafting (CABG). The present study aims to compare CABG-related outcomes between China and the United States among large teaching and urban hospitals. Observational analysis of patients aged ≥18 years, discharged from acute-care, large teaching and urban hospitals in China and the United States after hospitalization for an isolated CABG surgery. Data were obtained from the Chinese Cardiac Surgery Registry in China and the National Inpatient Sample in the United States. Analysis was stratified by 2 periods: 2007, 2008, and 2010; and 2011 to 2013 periods. The primary outcome was in-hospital mortality, and the secondary outcome was length of stay. The sample included 51 408 patients: 32 040 from 77 hospitals in the China-CABG group and 19 368 from 303 hospitals in the US-CABG group. In the 2007 to 2008, 2010 period and for all-age and aged ≥65 years, the China-CABG group had higher mortality than the US-CABG group (1.91% versus 1.58%, P =0.059; and 3.12% versus 2.20%, P =0.004) and significantly higher age-, sex-, and comorbidity-adjusted odds of death (odds ratio, 1.58; 95% confidential interval, 1.22-2.04; and odds ratio, 1.73; 95% confidential interval, 1.24-2.40). There were no significant mortality differences in the 2011 to 2013 period. For preoperative, postoperative, and total hospital stay, respectively, the median (interquartile range) length of stay across the entire study period between China-CABG and US-CABG groups were 9 (8) versus 1 (3), 9 (6) versus 6 (3), and 20 (12) versus 7 (5) days (all P <0.001). This difference did not change significantly over time. In 2011 to 2013, there was no significant difference in in-hospital mortality among patients who underwent an isolated CABG surgery in large teaching and urban hospitals in China and the United States. The longer length of stay in China may represent an opportunity for improvement. © 2017 The Authors.

Anti-angiogenesis Tyrosine kinase inhibitors (TKIs) have been proved to show promising effects on prolonging progression-free survival (PFS) for advanced sarcoma after failure of standard multimodal Therapy. Methylsulfonic apatinib is one of those TKIs which specifically inhibits VEGFR-2. This paper summarizes the experience of three Peking University affiliated hospitals in off-label use of apatinib in the treatment of extensively pre-treated sarcoma. We retrospectively analysed files of patients with advanced sarcoma not amenable to curative treatment, who were receiving an apatinib-containing regimen between June 1, 2015 and December 1, 2016. Fifty-six patients were included: 22 osteosarcoma, 10 Ewing's sarcoma, 3 chondrosarcoma and 21 soft tissue sarcoma. With median follow-up time of 6 months (range, 0.7-18.0 m), thirty-five (62.5%) patients had partial response, and disease was stable in 11 (19.6%). The 4-month and 6-month progression-free survival rates were 46.3 and 36.5%, respectively. The median duration of response was 3.8 months (95% CI 1.9-5.6 m), with much variability among disease subtypes. The median overall survival was 9.9 months (95% CI 7.6-12.2 m). Grade 3 and 4 toxicities were observed in 8 (14.3%) patients, the most common being hypertension, pneumothorax, wound-healing problems, anorexia, and rash or desquamation. Apatinib might be effective, with a high objective response rate, in an off-label study of sarcoma patients with advanced, previously treated disease. The duration of response was consistent with reports in different subtypes of sarcomas. Prospective trials of apatinib in the treatment of selected subtypes of sarcomas are needed. Retrospectively registered in the Medical Ethics Committee of Peking University People's Hospital, Peking University Shougang Hospital and Peking University International Hospital.

Since 1995, 1,1,1,2-tetrafluoroethane (CH2FCF3, HFC-134a) has become the most important substitute of CFC-12 in mobile air conditioning (MAC) in China and MAC sector has dominated all the emissions of HFC-134a. In this study, we developed an accurate, updated and county-level inventory of the HFC-134a emissions from MAC in China for the period of 1995-2030 with an improved bottom-up method. Our estimation indicated that the total HFC-134a emissions kept growing at increase rates of ∼100% per year for 1995-2000 and ∼34% per year for 2001-2010. In 2010, HFC-134a emissions from MAC in China reached 16.7 Gg (10.5-22.7 Gg at 95% confidential interval), equivalent to 21.7 Tg CO2 (CO2-eq). Furthermore, the emissions in China estimated in this study accounted for 9.8% of global HFC-134a emissions and 29.0% of total emissions from Non-Annex_I countries in 2010. Due to the more advanced social-economic conditions and more intensive ownership of automobiles, greater HFC-134a were observed to come from big cities in East China. Under a Business-as-usual (BAU) Scenario, projected emissions will grow to 89.4 (57.9-123.9) Gg (about 75.3-161.1 Tg CO2-eq) in 2030, but under an Alternative Scenario, 88.6% of the projected emissions under BAU scenario could be curbed. Our estimation demonstrates huge emission mitigation potential of HFC-134a in China's MAC sector.

Vaccine is the most effective way to protect susceptible children from varicella. Few published literature or reports on varicella vaccination of Chinese children exist. Thus, in order to obtain specific information on varicella vaccination of this population, we conducted this survey. We first used purposive sampling methods to select 6 provinces 10 counties from eastern, middle and western parts of China with high quality of Immunization Information Management System (IIMS), and then randomly select children from population in the IIMS, then we checked vaccination certificate on-site. Based on the varicella vaccination information collected from 481 children's vaccination certificates from all ten selected counties in China, overall coverage of the first dose of varicella vaccine was 73.6%. There is a positive linear correlation between per capita GDP and vaccine coverage at county level (r=0.929, P < 0.01). The cumulative vaccine coverage among children at 1 year, 2 years and ≥3 years old were 67.6%, 71.9% and 73.6% respectively (X2=4.53, P =0.10). The age of vaccination was mainly concentrated in 12-17 months. The coverage rate of the first dose of varicella vaccine in selected areas was lower than that recommended by WHO position paper. The coverage rate was relatively low in areas of low social-economic status. The cumulative coverage had no significant statistical difference among different age group. Most children received varicella vaccine before 3 years old. We suggest introducing the varicella vaccine into routine immunization program, to ensure universal high coverage among children in China. We also suggest that varicella vaccination information should be checked before entering school, in order to control and prevent varicella outbreaks in schools.

The aim of this study was to determine how malnutrition rates change in young Chinese children when 2006 World Health Organization (WHO) growth standards are used instead of 1978 WHO/National Center for Health Statistics reference. Cross-sectional survey data were used from rural western China and the Tibet region. The heights and weights of children of <36 months of age were measured. The nutritional status of the children was assessed by two references. Using 2006 reference instead of 1978 reference, the prevalence of stunting increased significantly (17.9% vs. 12.3% in rural western China and 37.5% vs. 28.1% in rural Tibet). The prevalence of underweight was lower in rural western China (7.7% vs. 11.7%) than rural Tibet (13.1% vs. 15.3%). For all ages, the prevalence of stunting increased and the greatest relative increase appeared in the first six months (102.9% in rural western China vs. 134.9% in rural Tibet). With respect to underweight, the relative increase occurred only during the first six months (314.3% in rural western China vs. 48.1% in rural Tibet); however, the reduction was observed in other age groups. For young Chinese Han and Tibetan children, the difference in estimation of malnutrition between two references differed in magnitude. The scale of change in the prevalence rates of stunting and underweight is much greater when 2006 reference was introduced. © The Author(s) 2013.

Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) is a cryptic species complex, causing significant crop losses in China during the last decade. Although knowledge of cryptic species composition and dynamics within B. tabaci complex is critical for developing sustainable pest management strategies, limited information is available on this pest in the Henan province of China. A systematic survey of the cryptic species composition and distribution of B. tabaci complex in different locations of Henan province was conducted in 2012. The results of RAPD-PCR and the gene for the mitochondrial cytochrome oxidase subunit-1 (mtCOI) based phylogenetic relationships established using Bayesian method indicated there were four known cryptic species MEAM1, MED, Asia II 3, Asia II 9 and a new cryptic species named China 6 in Henan province. In the survey, the invasive cryptic species MED and MEAM1 were found to be predominant with wide spread distribution across the surveyed regions. On the contrary, the indigenous B. tabaci cryptic species including Asia II 3, Asia II 9 and China 6 remained with low prevalence in some surveyed regions. Cryptic species MEAM1 and MED have not completely displaced the native B. tabaci in Henan province. This current study for the first time unifies our knowledge of the diversity and distribution of B. tabaci across Henan province of China. © The Authors 2017.

However, very little is understood on the metabolisms and ecological roles of this cosmopolitan sedimentary archaea , partly due to obstacles of cultivation. Bathyarchaeota could be divided into large members of subgroups with potentially high genetic heterogeneity, implying different metabolic capabilities and functions in different subgroups. Here, we report our work on investigating Bathyarchaeota abundance and types of subgroups in the South China Sea(SCS) sediments, aim to understand their ecological roles in the carbon cycling. Bathyarchaeota were found the most dominant archaeal group in the sediments of SCS , most of which belong to subgroups MCG-8, MCG-15, MCG-17 and MCG-3. A new pair of 16S rRNA gene primers was designed as the published primers could not cover MCG-15 and MCG-17, which are the most dominant subgroups in the SCS sediments. Comparing with previous primers which used for quantifying the abundance of Bathyarchaeota via Q-PCR, the new primer revealed about an order of magnitude higher abundance in all South China Sea sediments. The relationship of geochemical parameters and MCG subgroups will further be explored to provide the basis for further understanding the metabolic function and biogeochemical roles of these poor-understood sedimentary archaea.

To investigate the risk factors of peripartum hysterectomy in placenta previa through retrospective study of 3 840 placenta previa cases. The clinical data of 3 840 patients with placenta previa who delivered in West China Second University Hospital between Jan 2005 and June 2014 were analyzed retrospectively. The relationship of certain factors and peripartum hysterectomy was analyzed, including maternal age, residence place, parity, prior curettage, prior cesarean section, twin or multiple pregnancy, antenatal vaginal bleeding, type of placenta previa, suspected placenta accreta, antenatal level of hemoglobin and gestational age at delivery. The prevalence of placenta previa was 4.84%(3 840/79 304)in West China Second University Hospital during the study period, and the incidence of preipartum hysterectomy in patients with placenta previa was 2.76%(106/3 840). One-factor analysis demonstrated that residence place, parity, times of prior curettage, prior cesarean section, prenatal vaginal bleeding, anterior placenta, type of placenta previa, placenta accreta, antenatal anemia and gestational age at delivery were potential risk factors for peripartum hysterectomy(P<0.01). Variables with P<0.1 in one-factor analysis were introduced to multi-factor logistic regression analysis, which suggested that one prior cesarean section(OR=12.9,95% CI:6.3-26.3), two or more prior cesarean sections(OR=14.4, 95%CI:3.9-53.2), anterior placenta(OR=4.8, 95%CI:2.1-10.7), complete placenta previa(OR=5.9, 95%CI: 1.8-42.5), placenta accreta(OR=11.2, 95%CI:6.8-18.6), antenatal hemoglobin<100 g/L(OR=1.7, 95%CI: 1.0-2.8)and delivery before 34 gestational weeks(OR=3.2, 95%CI: 1.6-6.3)were independent risk factors of peripartum hysterectomy in patients with placenta previa(P<0.05). Prior cesarean section, anterior placenta, complete placenta previa, placenta accreta, antenatal anemia and delivery before 34 gestational weeks are high risk factors of peripartum hysterectomy in placenta previa patients. Perinatal care and risk evaluation before cesarean section are important to improve perinatal outcomes and reduce peripartum hysterectomy.

This paper provides an overview of prototyping research activities of automatically switched optical networks and transport networks (ASONs/ASTNs) in China. In recent years, China has recognized the importance and benefits of the emerging ASON/ASTN techniques. During the period of 2001 and 2002, the national 863 Program of China started the preliminary ASON research projects with the main objectives to build preliminary ASON testbeds, develop control plane protocols and test their performance in the testbeds. During the period of 2003 and 2004, the 863 program started ASTN prototyping equipment projects for more practical applications. Totally 12 ASTN equipments are being developed by three groups led by Chinese venders: ZTE with Beijing University of Posts and Telecommunications (BUPT), Wuhan Research Institute of Posts and Telecommunication (WRI) with Shanghai Jiao Tong University (SJTU), and Huawei Inc. Meanwhile, as the ASTN is maturing, some of the China"s carries are participating in the OIF"s World Interoperability Demonstration, carrying out ASTN test, or deploying ASTN backbone networks. Finally, several ASTN backbone networks being tested or deployed now will be operated by the carries in 2005. The 863 Program will carry out an ASTN field trail in Yangtse River Delta, and finally deploy the 3TNET. 3TNET stands for Tbps transmission, Tbps switching, and Tbps routing, as well as a network integrating the above techniques. A task force under the "863" program is responsible for ASTN equipment specifications and interoperation agreements, technical coordination among all the participants, schedule of the whole project during the project undergoing, and organization of internetworking of all the equipments in the laboratories and field trials.

This article is based upon a speech delivered by the author to a conference on population theory in memory of the centennial celebration of the death of Karl Marx. The conference was organized by the Institute of Population Theory of the Chinese People's University. According to the author, the only correct way to study population theory is to use the Marxist population theory as a guiding principle and integrate it with China's reality, and the format of dogmatism should not be adopted. The work on population theory studies should be established on a political and scientific foundation. The Chinese people should have a clear understanding of the goal of limiting China's population figure to under 1.2 billion at the end of this century. To reach this goal, the general public must be educated and understand to close relationship between family planning and the economic and social development of all of China. Family planning is a absolute necessity for the fundamental interests of China as a nation and as a people. Technical personnel and scientific theorists should be trained and organized in order that their work may satisfy the needs of China's reality. Family planning work should also be handled according to China's current situation.

Sexually transmitted diseases are becoming a serious public health problem in China. College students are recognized as one of the age groups most affected. The goal was to investigate premarital sexual activities and condom use among college students in Beijing in order to collect the information necessary for research on interventions. A cross-sectional survey was conducted in June 1999 among students at a university in Beijing. A self-administered, anonymous, structured questionnaire was used. Among those interviewed, 41% reported premarital sexual activities: 28% had kissed partners of the opposite sex, 19% had masturbated, and 12% had engaged in sexual intercourse. Among those who had sexual intercourse, 69% had used condoms. Today, more students are engaging in premarital sexual intercourse. Thus, it is necessary to reinforce reproductive health education among college students and provide convenient and optional services that are easily accessed.

Chinese women's reproductive patterns have changed significantly over the past several decades. However, relatively little is known about the pace and characteristics of these changes either overall or by region and socioeconomic status. We examined the cross-sectional data from the China Kadoorie Biobank cohort study that recruited 300 000 women born between 1930 and 1974 (mean age: 51 years) from 10 socially diverse urban and rural regions of China. Temporal trends in several self-reported reproductive characteristics, and effect modification of these trends by area and education (as a surrogate for socioeconomic status), were examined. The overall mean age at menarche was 15.4 (standard deviation 1.9) years, but decreased steadily over the 45 birth cohorts from 16.1 to 14.3 years, except for an anomalous increase of ∼1 year for women exposed to the 1958-61 famine in early adolescence. Similarly large changes were seen for other characteristics: mean parity fell (urban: 4.9 to 1.1; rural: 5.9 to 1.4); mean age at first birth increased (urban: 19.0 to 25.9 years; rural: 18.3 to 23.8 years); and birth spacing increased after 1980 to over 5 years. Breastfeeding declined after 1950 in urban and, after 1980, in rural women; and 68% of urban and 48% of rural women experienced a terminated pregnancy. Mean age at menopause increased from 47.9 to 49.3 years. There have been striking changes in reproductive factors over time and between areas among these Chinese women. Their effects on major chronic diseases should be investigated. © The Author 2014. Published by Oxford University Press on behalf of the International Epidemiological Association.

Pollutants from fishing boats have generally been neglected worldwide, and there is an acute shortage of measured emission data, especially in China. Therefore, on-board measurements of pollutants emitted from 12 different fishing boats in China (including gill net, angling, and trawler boats) were carried out in this study to investigate emission factors (EFs), characteristics and total emissions. The average EFs for CO 2 , CO, NO x , PM, and SO 2 were 3074 ± 55.9, 50.6 ± 31.7, 54.2 ± 30.7, 9.54 ± 2.24, and 5.94 ± 6.38 g (kg fuel) -1 , respectively, which were higher than those from previous studies of fishing boats. When compared to medium-speed and slow-speed engine vessels, high-speed engines on fishing boats had higher CO EFs but lower NO x EFs. Notably, when fishing boats were in low-load conditions, they always had higher EFs of CO, PM, and NO 2 compared to other operating modes. The estimated results showed that emissions from motor-powered fishing boats in China in 2012 (232, 379, and 61.8 kt CO, NO x and PM) accounted for 10.7%, 10.9%, and 19.3% of the total CO, NO x and PM emitted from nonroad mobile sources, which means significant contribution of fishing boats to air pollution, especially in southern China areas.

To investigate molecular characterization of streptococcus pyogenes isolates involved in an outbreak of scarlet fever in China in 2011. Seventy-four Streptococcal pyogenes involved in an outbreak of scarlet fever were isolated from pediatric patients in the areas with high incidence in China from May to August of 2011. Emm genotyping, pulsed-field gel electrophoresis (PFGE), superantigen (SAg) genes and antimicrobial susceptibility profiling were analyzed for these isolates. A total of 4 different emm types were identified. Emm12 was the most prevalent type which contained four predominating PFGE patterns corresponding to four different virulence and superantigen profiles. Emm12 (79.7%) and emm1 (14.9%) accounted for approximately 94% of all the isolates. The speA gene was all negative in emm12 isolates and positive in emm1 isolates. All strains were resistant to erythromycin, and 89.4% of them were resistant to erythromycin, tracycline, and clindamycin simultaneously. Several highly diversified clones with a high macrolide resistance rate comprise a predominant proportion of circulating strains, though no new emm type was found in this outbreak. The data provide a baseline for further surveillance of scarlet fever, which may contribute to the explanation of the outbreak and development of a GAS vaccine in China.

Funded by a NSF International Research Experience for Students (IRES) project (OIA: 1460034) at the University of Houston (http://ires.nsm.uh.edu), the author brought eight U.S. students to China in the summer of 2016. The host university at the China side is the China University of Geoscience at Wuhan. The international collaborative project is designed to expose U.S. students to the international landslide research community at an early stage of their careers. The NSF IRES program will support minimum 18 U.S. students (two graduates and four undergraduates per year) to conduct advanced landslide research in the Three Gorges area in China during the summers (eight weeks) of 2016, 2017, and 2018. The 2016 summer program includes a one-week-long pre-training at the University of Houston, a two-week-long intensive Chinese language and cultural course at the main campus of the China University of Geosciences (Wuhan), a four-week-long landslide field investigation in the Three Gorges Reservoir area, and a one-week-long wrap-up at the University of Houston. This presentation will introduce the experiences and lessons that we learned from the first-year activities of the international collaborative project.

Adsorption of anionic surfactant (sodium dodecylbenzenesulfonate, SDBS) and nonionic surfactant (an alcohol ethoxylates with 12 carbons and 9 oxyethyl groups, A12E9) mixtures, widely used as the major constituents of synthetic detergents in China and become the most common pollutants in the environment, on soils was conducted to investigate the behavior of mixed surfactants in soils. The effects of addition order and mixing ratios of two surfactants, associated with pH and ion strength in solutions, on adsorptions were considered. The results show that saturated adsorption amount of SDBS and A12E9 on soils decreased respectively when A12E9 was added into soils firstly compared with that secondly, possibly resulting from the screening of A12E9 to part adsorption sites on soils and the hydrocarbon chain-chain interactions between SDBS and A12E9. The adsorption of SDBS and A12E9 on soils was enhanced each other at pre-plateau region of isotherms. At plateau region of isotherms, the adsorption of SDBS on soils decreased with the increase of molar fraction of A12E9 in mixed surfactant solutions, while that of A12E9 increased except the molar ratio of SDBS to A12E9 0.0:1.0. With the increase of pH in mixed surfactant solutions, adsorption amount of SDBS and A12E9 on soils decreased, respectively. The reduction of ion strength in soils resulted in the decrease of adsorption amount of SDBS and A12E9 on soils, respectively.

Wang, Z.; Lu, M.

2011-01-01

The 12 May 2008 Wenchuan earthquake (M 7.9) occurred along the western edge of the eastern China SCR and was well recorded by modern strong-motion instruments: 93 strong-motion stations within 1.4 to 300 km rupture distance recorded the main event. Preliminary comparisons show some similarities between ground-motion attenuation in the Wenchuan region and the central and eastern United States, suggesting that ground motions from the Wenchuan earthquake could be used as a database providing constraints for developing GMPEs for large earthquakes in the central and eastern United States.

Summary The University Personality Inventory, a mental health instrument for college students, is frequently used for screening in China. However, its unidimensionality has been questioned. This study examined its dimensions to provide more information about the specific mental problems for students at risk. Four subsamples were randomly created from a sample (N = 6,110; M age = 19.1 yr.) of students at a university in China. Principal component analysis with Promax rotation was applied on the first two subsamples to explore dimension of the inventory. Confirmatory factor analysis was conducted on the third subsample to verify the exploratory dimensions. Finally, the identified factors were compared to the Sympton Checklist–90 (SCL–90) to support validity, and sex differences were examined, based on the fourth subsample. Five factors were identified: Physical Symptoms, Cognitive Symptoms, Emotional Vulnerability, Social Avoidance, and Interpersonal Sensitivity, accounting for 60.3% of the variance. All the five factors were significantly correlated with the SCL–90. Women significantly scored higher than men on Cognitive Symptoms and Interpersonal Sensitivity. PMID:25933045

A novel thermophilic actinomycete, designated strain 3-12X T , was isolated from mushroom compost in Guangxi University, Nanning, China. The novel isolate contained meso-diaminopimelic acid as the diagnostic diamino acid and the whole-cell sugars were glucose and ribose. The predominant menaquinones were MK-9(H4) and MK-9(H6). The polar phospholipids were diphosphatidylglycerol, hydroxy-phosphatidylethanolamine, phosphatidylmethylethanolamine, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside, ninhydrin-positive phosphoglycolipids and glycolipids. Major fatty acids were so-C16 : 0 and C17 : 0. The G+C content of the genomic DNA was 74.6 %. The 16S rRNA gene sequence analysis showed that the closest phylogenetic neighbour of strain 3-12X T was Thermomonospora chromogena ATCC 43196 T (97.0 %), other closely related strains all belonged to the family Streptosporangiaceae and showed more than 6 % divergence. The chemotaxonomic characteristics of strain 3-12X T were significantly different from Thermomonospora chromogena ATCC 43196 T and DNA-DNA hybridization showed low relatedness (48.6-55.6 %) between them, so they should be different species. Thermomonospora chromogena was removed from the genus Thermomonospora by Zhang et al. 1998 on the basis of phylogenetic, chemotaxonomic and phenotypic evidence, but its taxonomic position remains uncertain. Based on the phenotypic and phylogenetic data, strain 3-12X T represents a novel species in a new genus in the family Streptosporangiaceae. The name Thermostaphylospora griseoalba gen. nov., sp. nov. is proposed. The type strain of Thermostaphylospora grisealba is 3-12X T (=DSM 46781 T =CGMCC 4.7160 T ). We also propose transferring Thermomonospora chromogenaZhang et al. 1998 to Thermostaphylospora chromogena comb. nov. (type strain ATCC 43196 T =JCM 6244 T ).

As part of our ongoing influenza surveillance program in South China, 19 field strains of H9N2 subtype avian influenza viruses (AIVs) were isolated from dead or diseased chicken flocks in Guangdong province, South China, between 2012 and 2013. Hemagglutinin (HA) genes of these strains were sequenced and analyzed and phylogenic analysis showed that 12 of the 19 isolates belonged to the lineage h9.4.2.5, while the other seven belonged to h9.4.2.6. Specifically, we found that all of the viruses isolated in 2013 belonged to lineage h9.4.2.5. The lineage h9.4.2.5 viruses contained a PSRSSR↓GLF motif at HA cleavage site, while the lineage h9.4.2.6 viruses contained a PARSSR↓GLF at the same position. Most of the isolates in lineage h9.4.2.5 lost one potential glycosylation site at residues 200-202, and had an additional one at residues 295-297 in HA1. Notably, 19 isolates had an amino acid exchange (Q226L) in the receptor binding site, which indicated that the viruses had potential affinity of binding to human like receptor. The present study shows the importance of continuing surveillance of new H9N2 strains to better prepare for the next epidemic or pandemic outbreak of H9N2 AIV infections in chicken flocks.

The Dai people are one of the ethnic minorities in China and have a population of 1,260,000. They have the same origin as one of the main ethnic groups in Laos and Thailand. The study aims to describe the dental caries and gingival status of 12-year-old Dai children in China and to study the factors affecting their oral-health status. This cross-sectional oral-health survey was conducted from 2011-2012 with ethics approval. A sample of 12-year-old Dai children living in Yunnan, China, was selected using a multistage and cluster sampling method. One trained examiner performed the clinical examination. Caries experience was measured using DMFT index, and gingival status was assessed with CPI index. A self-completed questionnaire was sent to the children, and they were asked about their backgrounds and oral-health-related behaviors and oral-health knowledge. Binary logistic regression analysis was performed to investigate the factors that affected the caries status. A total of 875 children were invited, and 823 (94 %) joined the survey. The prevalence of caries experience among the participants was 40 %. The mean DMFT and DT scores were 0.9 and 0.8, respectively. Most children (93 %) had gingivitis, and many (46 %) had calculus. Girls and those who had visited a dentist during the previous year had a higher prevalence of caries. Dental caries were prevalent among 12-year-old Dai children in China. The periodontal condition of most of the children was poor. Caries were associated with gender and dental attendance.

OBJECTIVES—To compare background and process variables, as well as follow up status, of the participants in the International Quit and Win '96 contests of China and Finland, and analyse factors contributing to sustained maintenance.
DESIGN—A standardised 12 month follow up was conducted in both countries with random samples of participants. The sample sizes were 3119 in China and 1448 in Finland, with response rates of 91.2% and 65.2%, respectively.
INTERVENTIONS—The International Quit and Win '96 contest was the second coordinated, multinational smoking cessation campaign targeted at adult daily smokers. Altogether 25 countries participated, including China with 15 000 and Finland with 6000 smokers registered.
MAIN OUTCOME MEASURES—Conservative (considering all non-respondents relapsed) and non-conservative (based on respondents only) estimates were calculated for one month abstinence, 12 month continuous abstinence, and point abstinence at the time point of follow up.
RESULTS—Great differences were found in the background and process variables, as well as in the outcome measures. At one year follow up, the conservative continuous abstinence rates show that the Chinese participants maintained their abstinence better (38%) compared to the Finnish ones (12%). In China women reached higher abstinence rate (50%) than men (36%), whereas in Finland men achieved a better result (14%) than women (9%).
CONCLUSIONS—The Quit and Win contest is a mass smoking cessation method feasible in countries showing great variance in smoking habits and rates. However, in countries with different stages of anti-smoking development, such as China and Finland, different practical implementation strategies may be needed.

The Japan-China Joint Medical Workshop on Drug Discoveries and Therapeutics 2008 (JCMWDDT 2008) was held from September 29 to October 1, 2008 at The University of Tokyo, Tokyo, Japan. JCMWDDT is an international workshop that is mainly organized by Asian editorial members of Drug Discoveries & Therapeutics (http://www.ddtjournal.com/home) for the purpose of promoting research exchanges in the field of drug discovery and therapeutic. This year's JCMWDDT is the second workshop and focused particularly on novel development and technological innovation of anti-influenza agents. The workshop began with an announcement by the Japanese Co-chairperson, Dr. Sekimizu (Department of Microbiology, Graduate School of Pharmaceutical Sciences, The University of Tokyo, Japan; Editorin- Chief of Drug Discoveries & Therapeutics, DDT) followed by a speech by the Chinese Co-chairperson, Dr. Wenfang Xu (School of Pharmaceutical Sciences, Shandong University, Shandong, China; Editor in China Office of DDT), with additional speeches by Dr. Norio Matsuki (The University of Tokyo, Japan; Editor of DDT) and Dr. Guanhua Du (Chinese Academy of Medical Science, China; Editor of DDT). Fifty-nine titles were presented in 6 specialized sessions (Research Advances in Drug Discoveries and Therapeutics, Drug Synthesis/Clinical Therapeutics, Medicinal Chemistry/Natural Products, Anti-influenza Drugs, Anti-infection/antiviral Drugs, Biochemistry/Molecular Biology /Pharmacology) and a poster session (Drug Discov Ther 2008; 2, Suppl; available at http://www.ddtjournal.com/Announce/index.htm). An annual outbreak of avian influenza in Asian countries including China and Japan has sparked fears that the virus will mutate and then cause an epidemic in humans. Therefore, Asian researchers need to work together to control this infection. This year's JCMWDDT helped provide an opportunity to reiterate the crucial role of medicinal chemistry in conquering influenza and created an environment for cooperative research in Asian countries.

Municipal Solid Waste (MSW) is a heterogeneous waste stream, which is harmful for human health and the ecological environment if it is not well managed. Based on results from different authors by analyzing the generation, physical components and management of MSW from different cities, this paper presents an overview of the temporal trends and spatial variation characterization of MSW generation and its physical components in China. Total MSW generation has increased from 31,320 thousand tons in 1980 to 178,602 thousand tons in 2014, and MSW generation per capita has also increased from 448.3g to 653.2g. The distribution of MSW generation is mostly concentrated in the coastal southeastern region, as well as large point sources of more than 200 thousand tons per year are mostly distributed in Jiangsu, Zhejiang, Shandong, Hebei and Guangdong provinces. The review shows that the largest proportion of food waste, plastics and paper is 61.2% (54.2-65.9%, 95% CI), 9.8% (7.2-14.0%, 95% CI), 9.6% (6.7-12.3%, 95% CI), respectively, in 2014; the best estimates of other waste were as follows: 3.1% textile, 2.1% glass, 1.1% metal, 1.8% wood and grass, 1.3% rubber and leather, 1.8% ceramic, 2.5% ash, 1.2% hazardous waste, and 4.5% miscellaneous. To better manage China's MSW, several possible and appropriate solutions (e.g., concentrating on key regions, intensifying source separation, promoting green lifestyle, and establishing specialized regulations and policies) should be adopted, which might facilitate the application of China's 13th Five, and identify gaps in our knowledge of MSW management subject.

A rapid expansion of hand, foot, and mouth disease (HFMD) outbreaks has occurred and caused deaths in China in recent years, but little is known about the other etiologic agents except enterovirus 71 (EV71) and coxsackievirus A 16 (CA16). The objective of this study is to determine the genotype compositions of enterovirus causing HFMD in Shanghai and identify any associations between enterovirus types and clinical manifestations. Stool specimens were collected from patients hospitalized for treatment of HFMD, from May 2010 to April 2011. Enterovirus was detected by reverse transcription PCR and directly genotyped by sequencing the PCR products. Phylogenetic analysis was based on the VP1 partial gene. Of 290 specimens, 277 (95.5%) tested positive for enterovirus. The major genotypes were EV71 (63.8%), CA10 (9.0%), CA6 (8.3%), CA16 (6.9%), CA12 (2.4%), and CA4 (1.4%). The EV71 strains belonged to the C4a subtype and CA16 belonged to the B subtype. CA6 was closely related to strains detected in Japan, Taiwan and China, and CA10, CA12 and CA4 were phylogenetically similar to other strains circulating in China. Mean hospital stays and the prevalence of complications in patients with EV71 infection were higher than those in patients in CA6, CA10 or CA16 infection (P < 0.05 for all comparisons). Children with CA12 infection were the youngest, and most likely have the highest risk of complications when compared to the other non-EV71 infection groups. This study demonstrated a diversified pathogen compositions attributing to HFMD and clinical symptoms differing in enterovirus genotypes. It deserves our attention as early identification of enterovirus genotypes is important for diagnosis and treatment of HFMD patients.

The China Medical Board organized a management conference for the presidents of China's national medical universities. A three-person consulting team arranged by the Association of American Medical Colleges led the conference. Designed as a preliminary examination of the management problems faced by the national medical universities, the conference covered content similar to that of the AAMC Executive Development Seminars, including governance, financial management, faculty practice plans, technology transfer, information management, and organizational diagnosis. China's national medical universities are strategically managed by the Ministry of Public Health in Beijing, and for several years the ministry has increasingly decentralized the management and operational planning and control of these universities. The universities do not have enough properly trained personnel to absorb the additional management responsibilities, and the university presidents feel that they and their senior staffs need extensive training in adapting western-style management principles and practice to the Chinese setting.

Norovirus (NoV) has been recognized as the most important cause of nonbacterial acute gastroenteritis affecting all age group people in the world. Genetic recombination is a common occurance in RNA viruses and many recombinant NoV strains have been described since it was first reported in 1997. However, the knowledge of recombinant NoV in China is extremely limited. A total of 685 stool specimens were tested for NoV infection from the acute gastroenteritis patients who visited one general hospital in Beijing from April 2009 to November 2011. The virus recombination was identified by constructing phylogenetic trees of two genes, further SimPlot and the maximum chi-square analysis. The overall positive rate was 9.6% (66/685). GII.4 New Orleans 2009 and GII.4 2006b variants were the dominant genotype. Four GII.g/GII.12 and one GII.12/GII.3 recombinant strains were confirmed, and all derived from adult outpatients. The predictive recombination point occurred at the open reading frame (ORF)1/ORF2 overlap. The GII.g ORF1/GII.12ORF2 recombinant has been reported in several countries and it was the first report of this recombinant in China.

This study aims at qualifying air pollutants and environmental impacts generated from coal-based power plants and providing useful information for decision makers on the management of coal-based power plants in China. Results showed that approximately 9.03, 54.95, 62.08, and 12.12% of the national carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter emissions, respectively, in 2011were generated from coal-based electricity generation. The air pollutants were mainly generated from east China because of the well-developed economy and energy-intensive industries in the region. Coal-washing technology can simply and significantly reduce the environmental burden because of the relativity low content of coal gangue and sulfur in washed coal. Optimizing the efficiency of raw materials and energy consumption is additional key factor to reduce the potential environmental impacts. In addition, improving the efficiency of air pollutants (e.g., dust, mercury, sulfur dioxide, nitrogen oxides) control system and implementing the strict requirements on air pollutants for power plants are important ways for reducing the potential environmental impacts of coal-based electricity generation in China.

To assess the challenges to and provide a response strategy for the development of nursing and make suggestions for promoting the nursing discipline, platform, and talent teams based on current best available evidence. We searched CNKI(China National Knowledge Infrastructure), VIP information(Chinese Scientific Journals database), CBM(Chinese Biomedical Literature database), and Web sites of the World Health Organization, International Council of Nurses, World Bank, the Ministry of Health and the Ministry of Education of China, and relevant schools in China. Data analyses were performed using SPSS 13.0. We identified 886 nursing schools in China in 2012. Results showed that 38,212 nursing students were enrolled in universities or independent colleges and 130,837 nursing student were enrolled in colleges or senior vocational schools. The doctor-to-nurse ratio was 1:0.9 in 2010. The actual demand for doctors was 2.6 million, whereas the nursing shortage was approximately 346,000. Nurses aged ≤ 35 years accounted for 50% of the total. A total of 64% to 69% of nurses had primary professional titles; fewer than 2.5% of those had advanced titles. The training costs for one doctor or one nurse in China was only two-fifths that in India and one-fifth to one-fourth that in sub-Saharan Africa. To date, only 30.1% of disaster nursing studies in China provided research data; 30.6% were related to clinical experience and 38.3% were reviews. Education and health systems need to be extensively reformed. It is necessary to train nursing students with core competencies using transformative learning. It is necessary to update textbooks and teaching methods, and funding should be appropriately increased. Nursing should co-operate with other disciplines, and apply evidence-based nursing methods to improve the quality of healthcare services and patient satisfaction. © 2013 Wiley Publishing Asia Pty Ltd and Chinese Cochrane Center, West China Hospital of Sichuan University.

Pension Reform in China.

PubMed

Liu, Tao; Sun, Li

2016-01-01

This article analyzes China's pension arrangement and notes that China has recently established a universal non-contributory pension plan covering urban non-employed workers and all rural residents, combined with the pension plan covering urban employees already in place. Further, in the latest reform, China has discontinued the special pension plan for civil servants and integrated this privileged welfare class into the urban old-age pension insurance program. With these steps, China has achieved a degree of universalism and integration of its pension arrangement unprecedented in the non-Western world. Despite this radical pension transformation strategy, we argue that the current Chinese pension arrangement represents a case of "incomplete" universalism. First, its benefit level is low. Moreover, the benefit level varies from region to region. Finally, universalism in rural China has been undermined due to the existence of the "policy bundle." Additionally, we argue that the 2015 pension reform has created a situation in which the stratification of Chinese pension arrangements has been "flattened," even though it remains stratified to some extent.

The effect of future reduction in aerosol emissions on climate extremes in China

This study investigates the effect of reduced aerosol emissions on projected temperature and precipitation extremes in China during 2031-2050 and 2081-2100 relative to present-day conditions using the daily data output from the Community Earth System Model ensemble simulations under the Representative Concentration Pathway (RCP) 8.5 with an applied aerosol reduction and RCP8.5 with fixed 2005 aerosol emissions (RCP8.5_FixA) scenarios. The reduced aerosol emissions of RCP8.5 magnify the warming effect due to greenhouse gases (GHG) and lead to significant increases in temperature extremes, such as the maximum of daily maximum temperature (TXx), minimum of daily minimum temperature (TNn), and tropical nights (TR), and precipitation extremes, such as the maximum 5-day precipitation amount, number of heavy precipitation days, and annual total precipitation from days ˃95th percentile, in China. The projected TXx, TNn, and TR averaged over China increase by 1.2 ± 0.2 °C (4.4 ± 0.2 °C), 1.3 ± 0.2 °C (4.8 ± 0.2 °C), and 8.2 ± 1.2 (30.9 ± 1.4) days, respectively, during 2031-2050 (2081-2100) under the RCP8.5_FixA scenario, whereas the corresponding values are 1.6 ± 0.1 °C (5.3 ± 0.2 °C), 1.8 ± 0.2 °C (5.6 ± 0.2 °C), and 11.9 ± 0.9 (38.4 ± 1.0) days under the RCP8.5 scenario. Nationally averaged increases in all of those extreme precipitation indices above due to the aerosol reduction account for more than 30 % of the extreme precipitation increases under the RCP8.5 scenario. Moreover, the aerosol reduction leads to decreases in frost days and consecutive dry days averaged over China. There are great regional differences in changes of climate extremes caused by the aerosol reduction. When normalized by global mean surface temperature changes, aerosols have larger effects on temperature and precipitation extremes over China than GHG.

The cases of human infections with H10N8 viruses identified in late 2013 and early 2014 in Jiangxi, China, have raised concerns over the origin, prevalence, and development of these viruses in this region. Our long-term influenza surveillance of poultry and migratory birds in southern China in the past 12 years showed that H10 influenza viruses have been introduced from migratory to domestic ducks over several winter seasons at sentinel duck farms at Poyang Lake, where domestic ducks share their water body with overwintering migratory birds. H10 viruses were never detected in terrestrial poultry in our survey areas until August 2013, when they were identified at live-poultry markets in Jiangxi. Since then, we have isolated 124 H10N8 or H10N6 viruses from chickens at local markets, revealing an ongoing outbreak. Phylogenetic analysis of H10 and related viruses showed that the chicken H10N8 viruses were generated through multiple reassortments between H10 and N8 viruses from domestic ducks and the enzootic chicken H9N2 viruses. These chicken reassortant viruses were highly similar to the human isolate, indicating that market chickens were the source of human infection. Recently, the H10 viruses further reassorted, apparently with H5N6 viruses, and generated an H10N6 variant. The emergence and prevalence of H10 viruses in chickens and the occurrence of human infections provide direct evidence of the threat from the current influenza ecosystem in China. After the outbreak of avian-origin H7N9 influenza viruses in China, fatal human infections with a novel H10N8 virus were reported. Utilizing data from 12 years of influenza surveillance in southern China, we showed that H10 viruses were regularly introduced by migratory ducks to domestic ducks on Poyang Lake, a major aggregative site of migratory birds in Asia. The H10 viruses were maintained and amplified in domestic ducks and then transmitted to chickens and reassorted with enzootic H9N2 viruses, leading to an outbreak and human infections at live-poultry markets. The emergence of the H10N8 virus, following a pathway similar to that of the recent H7N9 virus, highlights the role of domestic ducks and the current influenza ecosystem in China that facilitates influenza viruses moving from their reservoir hosts through the live-poultry system to cause severe consequences for public health.

2016-12-01

With the ending of one-child policy since 2015, the number of newborns are expected to increase in China, where people are surviving from pool air quality. Air pollutants, especially PM2.5 have been confirmed as a top risk factor to cause birth defects including low birth weight (LBW). Motivated by the increasing demands of the newborns for cleaner air in China, we conducted the first national risk assessment study on LBW cases caused by PM2.5. We combined county-level PM2.5 concentrations in 2013-2015 and demographic data (including population counts, birth rates and etc.), province-level baseline incidences of LBW and multiple reference safety concentrations (0 μg/m3, WHO air quality guidelines and interim targets) to estimate the number of PM2.5-associated LBW in 31 provinces. The uncertainty was quantified using Monte Carlo simulations. Based on our results, in 2013 among 334,781 (95% CI: 313,024-344,568) cases of LBW, 122,684 (95% CI: 53,153-173,846, account for 37% of the total LBW) were attributed to PM2.5, when assuming the reference safety concentration as 0 μg/m3; while 53,917 (95% CI: 22,851-82,195, account for 16% of the total LBW) cases of LBW could have been protected, if the air quality met WHO WHO interim target-3, 35 μg/m3. Among 31 provinces, PM2.5-associated LBW were mostly distributed in Hebei (12.99%, 95% CI: 12.42%-17.30%), Henan (9.75%, 95% CI: 9.11%-13.50%) and Guangdong (8.60%, 95% CI: 6.98%-9.42%). During 2013 to 2015, air quality in China was reported to be improved by implement of emission-reduction policies. Similarly, we found significantly decreasing trends of infants weighted concentrations of PM2.5 in most heavily polluted areas, which protected 12,201 (95% CI: 4,749-20,503) and 24,637 (95% CI: 9,619-39,821) PM2.5-associated LBW in 2014 and 2015, account for 3.64% (95% CI: 1.46%-6.21%) and 7.36% (95% CI: 2.93%-12.07%) of that in 2013, respectively. The uncertainty of this study was mainly contributed by that in epidemiology-based relative risk of PM2.5 on LBW and baseline incidences. In addition, the estimated numbers of PM2.5-associated LBW were also sensitive to choice of reference safety concentrations. Nevertheless, the study indicated that more effectors to clean air pollutants should be considered to protect future newborns in China.

This study examined the frequency of mobile phone dependence in Chinese university students and explored its association with social support and impulsivity. Altogether, 909 university students were consecutively recruited from a large university in China. Mobile phone use, mobile phone dependence, impulsivity, and social support were measured with standardized instruments. The frequency of possible mobile phone use and mobile phone dependence was 78.3% and 7.4%, respectively. Multinomial logistic regression analyses revealed that compared with no mobile phone dependence, possible mobile phone dependence was significantly associated with being male (p = 0.04, OR = 0.7, 95% CI: 0.4–0.98), excessive mobile phone use (p < 0.001, OR = 1.2, 95% CI: 1.09–1.2), and impulsivity (p < 0.001, OR = 1.05, 95% CI: 1.03–1.06), while mobile phone dependence was associated with length of weekly phone use (p = 0.01, OR = 2.5, 95% CI: 1.2–5.0), excessive mobile phone use (p < 0.001, OR = 1.3, 95% CI: 1.2–1.4), and impulsivity (p < 0.001, OR = 1.08, 95% CI: 1.05–1.1). The frequency of possible mobile phone dependence and mobile phone dependence was high in this sample of Chinese university students. A significant positive association with impulsivity was found, but not with social support. PMID:29533986

Polycyclic aromatic hydrocarbons (PAHs) and its oxygenated derivatives (OPAHs) are toxins in PM2.5. Little information has been known for their transformation in the ambient airs. In this study, PM2.5 samples were collected at 19 sampling sites in Xi'an, China during the heating period, which is classified into: urban residential, university, commercial area, suburban region, and industry. Organic compounds including PAHs, OPAHs, hopanes and cholestanes were quantified. The average of total quantified PAHs and OPAHs concentrations were 196.5 ng/m(3) and 29.4 ng/m(3), respectively, which were consistent with other northern cities in China. Statistical analyses showed that there were significant differences on the distributions of PAHs between urban and suburban regions. The industry also had distinguishable profiles compared with urban residential and commercial area for OPAHs. The greater diversity of OPAHs than PAHs might be due to different primary emission sources and transformation and degradation pathways. The ratios of OPAHs to the corresponding parent PAHs, including 9-fluorenone/fluorene, anthraquinone/anthracene, benz[a]anthracene-7,12-dione/benzo[a]anthracene were 6.2, 12.7, and 1.4, respectively, which were much higher than those for the fresh emissions from coal combustion and biomass burning. These prove the importance of secondary formation and transformation of OPAHs in the ambient airs. Biomarkers such as retene, cyclopenta[CD]pyrene and αα-homohopane were characterized for the source apportionment. With Positive Matrix Factorization (PMF) model analysis, biomass burning was recognized as the most dominant pollution sources for PAHs during the heading period, which accounted for a contribution of 37.1%. Vehicle emission (22.8%) and coal combustion (22.6%) were also contributors in Xi'an. Copyright © 2016 Elsevier Ltd. All rights reserved.

Pyrethroid resistance was one of the main reasons for control failure of cotton bollworm Helicoverpa armigera (Hübner) in China. The promotion of Bt crops decreased the application of chemical insecticides in controlling H.armigera. However, the cotton bollworm still kept high levels of resistance to fenvalerate. In this study, the resistance levels of 8 field-collected strains of H. armigera from north of China to 4 insecticides, as well as the expression levels of related P450 genes were investigated. The results of bioassay indicated that the resistance levels to fenvalerate in the field strains varied from 5.4- to 114.7-fold, while the resistance levels to lambda-cyhalothrin, phoxim and methomyl were low, which were ranged from 1.5- to 5.2-, 0.2- to 1.6-, and 2.9- to 8.3- fold, respectively, compared to a susceptible strain. Synergistic experiment showed that PBO was the most effective synergist in increasing the sensitivity of H. armigera to fenvalerate, suggesting that P450 enzymes were involved in the pyrethroid resistance in the field strains. The results of quantitative RT-PCR indicated that eight P450 genes (CYP332A1, CYP4L11, CYP4L5, CYP4M6, CYP4M7, CYP6B7, CYP9A12, CYP9A14) were all significantly overexpressed in Hejian1 and Xiajin1 strains of H. armigera collected in 2013, and CYP4L5 was significantly overexpressed in all the 6 field strains collected in 2014. CYP332A1, CYP6B7 and CYP9A12 had very high overexpression levels in all the field strains, indicating their important roles in fenvalerate resistance. The results suggested that multiple P450 genes were involved in the high-level fenvalerate-resistance in different field strains of H. armigera collected from north of China.

The pesticide residue levels of three nuts (chestnut, walnut, pinenut) collected from seven main producing areas of China were investigated. Twenty-nine pesticides, including organophosphates (OPs), organochlorines (OCs), pyrethroids (PYs) and two fungicides (triadimefon and buprofezin) were analyzed by gas chromatography (GC). Four OPs (acephate, dimethoate, chlorpyrifos and parathion-methyl) were found in 11.4% samples, with the concentrations of 19.0 µg kg(-1) to 74.0 µg kg(-1). Six OCs (DDT, HCH, endosulfan, quintozene, aldrin and dieldrin) were found in 18.2% samples, with the concentrations of 2.0 µg kg(-1) to 65.7 µg kg(-1). Among OCs, p,p-DDE and α-HCH were the dominant isomer for DDT and HCH. Five PYs (fenpropathrin, fenvalerate, cypermethrin, bifenthrin and cyhalothrin) were found in 15.9% samples, with the concentrations of 2.5 µg kg(-1) to 433.0 µg kg(-1). Fenpropathrin was the most frequently detected pesticide. In addition, triadimefon and buprofezin were detected only in two samples. For the tested nuts, 25.0% samples with multiple residues (containing more than two pesticides) were noted, even up to 9.1% samples with five pesticide residues. The residue of 15.9% samples was higher than the maximum residue limits (MRLs) of China. The short-term risks for the tested nuts were below 1.2%, and the highest long-term risk was 12.58%. The cumulative risk (cHI) for the tested pesticides were 8.43% (OPs), 0.42% (OCs), 12.82% (PYs) and 0.15% (fungicides), respectively. The total cHI was 21.82%. There was no significant health risk for consumers via nuts consumption. Copyright © 2015 Elsevier Ltd. All rights reserved.

However, the reported rates of morbidity and mortality vary among different regions of China, and the exact rates in Northeast China are unknown. This study aimed to determine neonatal morbidity and mortality rates and the associated risk factors in Northeast China. Neonates born in 2005 at seven hospitals in five major cities of Heilongjiang province in Northeast China were recruited. Standardized questionnaires on both the mother and neonate were conducted by trained investigators. The questions included demographic data on the mother, the mother's weight, gestational age (GA), complications during pregnancy, method of delivery, neonate's gender, weight, general health situation, and complications after delivery. Results: A total of 5,277 neonates were included, with a male to female ratio of 1.07. The incidence ofpreterm delivery was 8.7%, which was associated with an increased age of the mother, a history of preeclampsia-eclampsia, premature rupture of membranes, and intrauterine distress. Morbidity occurred in 7.0% of neonates, including hypoxic ischemic encephalopathy (2.4%), asphyxia (1.6%), pneumonia (1.6%), hyperbilirubinemia (0.5%), intracranial hemorrhage (0.5%), meconium as- piration syndrome (0.2%), and ingestion syndrome (0.2%). The overall mortality was 9.5%0. Preterm delivery, maternal history ofpreeclamp- sia-eclampsia, hypoxic ischemic encephalopathy, intracranial hemorrhage, pneumonia, asphyxia, and meconium aspiration syndrome were independent risk factors for mortality with odds ratios (95% confidence interval) of 17.42 (7.31-38.9), 12.52 (Table 3) (3.91-16.82), 10.13 (2.52-19.86), 9.77 (2.35-19.93), 4.15 (1.78-9.52), 2.18 (1.21-5.47), and 2.76 (2.11-6.32), respectively (all P<0.01). In 2005, the overall morbidity and mortality was 7.0% and 9.5%0, respectively in northeast China, and preterm delivery was the highest risk factor for neonatal mortality. The prevention on preterm delivery should be a top priority for the improvement of neonatal healthcare.

There is little information regarding the obesity epidemical situation and risk factors of childhood hypertension (HTN) in China. The present study aimed to determine the prevalence of HTN/prehypertension (PHTN), as well as the associated risk factors, among adolescents in Changsha city, China. A total of 88,974 adolescents from 49 middle schools in Changsha city between 12 and 17 years of age were examined during 2009. Body weight, height, and blood pressure (BP) were measured in all adolescents. HTN and PHTN were defined according to sex- and age-specific Chinese reference data. Overweight and obesity were also defined according to sex- and age-specific Chinese reference data. It was determined that the prevalence of PHTN and HTN were 7.2 and 3.1%, respectively. Furthermore, 14.6% of male adolescents were overweight and 7.0% were obese, whereas 8.6% of female adolescents were overweight and 2.9% were obese. The risk ratio (RR) of HTN were significantly higher in overweight (RR: 2.8, 95% confidence interval (CI): 2.6-3.2) and obese (RR: 8.7, 95% CI: 8.1-9.5) adolescents adjusted for age, sex, and height. Chinese reference data were used to evaluate BP and body mass index (BMI) of children and adolescents. Higher prevalence of HTN was associated with higher BMI percentiles. Being overweight or obese markedly increased the risk of both HTN and PHTN among adolescents between 12 and 17 years of age in Changsha city, China.

AIM: To determine the GI of some cereals and tubers produced in China in an effort to establish the database of glycemic index (GI) of Chinese food. METHODS: Food containing 50 g carbohydrate was consumed by 8-12 healthy adults after they have been fasted for 10 h and blood glucose was monitored for 2 h. Glucose was used as reference food. GI of food was calculated according to a standard method. RESULTS: GI of 9 types of sugar and 60 kinds of food were determined. CONCLUSION: Food GI is mainly determined by nature of carbohydrate and procession. Most of cereals and tubers produced in China have similar GI with their counterparts produced in other countries.

Here we provide the first high resolution records of soil pH and MAAT since the last glacial maximum based on the sedimentary core of MD05-2896 in the southern South China Sea. The MAAT record exhibited typical glacial and interglacial cycles and was consistent with the winter insolation variation. The pH values were lower (6.4-7) in the glacial time and higher (7-8.4) in the interglacial time. Changes in soil pH allowed the evaluation of changes in soil CO2 based on the atmosphere-soil CO2 balance. The results imply that the lower winter MAAT variation with a lower winter atmospheric CO2 concentration might have resulted in a higher pH in the interglacial period. Our records provide a new insight into the evolution of atmospheric CO2 between glacial and interglacial cycles in East Asia. Key words: South China Sea, MBT/CBT, b-GDGTs, MAAT, pH

The constituents of Cimicifuga plants have been extensively investigated, and the principal metabolites are 9, 19-cyclolanostane triterpenoid glycosides, which often exhibit extensive pharmacological activities. 9, 19-Cyclolanostane triterpenoid glycosides are distributed widely in genus Cimicifuga rather than in other members of the Ranunculaceae family. So far, more than 140 cycloartane triterpene glycosides have been isolated from Cimicifuga spp.. The aim of this review was to summarize all 9, 19-cyclolanostane triterpenoid glycosides based on the available relevant scientific literatures from 2000 to 2014. Biological studies of cycloartane triterpene glycosides from Cimicifuga spp. are also discussed. Copyright © 2016 China Pharmaceutical University. Published by Elsevier B.V. All rights reserved.

Tooth wear has been investigated in numerous countries, and the prevalence has varied. However, the data on tooth wear in China are scarce. The aim of this study was to describe the prevalence of tooth wear and to investigate the relative indicators associated with tooth wear in 12- and 15-year-old adolescents in Wuhan City, Hubei Province, Central China. A cross-sectional descriptive study was undertaken among 720 adolescents in Hubei Province, Central China. The age groups in this study were 12- and 15-year-old, and each group consisted of 360 participants in which females and males represented 50 % each. A modified version of the Basic Erosive Wear Examination (BEWE) tooth wear index was used for the buccal, cervical, occlusal/incisal and lingual surfaces of all of the teeth in the 720 adolescents. All of the participants were asked to answer a questionnaire consisting of questions about their current and historical dietary habits and oral hygiene. The prevalence of tooth wear was 18.6 and 89.4 % in 12- and 15-year-old adolescents, respectively. The prevalence rates of dentin exposure were 1.9 and 5.6 %, respectively. A significantly higher prevalence of tooth wear and dentin exposure in 15-year-old adolescents was found than in 12-year-old adolescents (p < 0.001 and p = 0.011). Several factors such as drinking soft drinks and fruit juices immediately after sports, taking aspirin, reflux, unilateral chewing, tooth brushing once daily or less often, duration of brushing less than 2 min and swimming in the summer were found to be associated with tooth wear. Tooth wear in 12- and 15-year-old adolescents in Central China is a significant problem and should receive greater attention. The prevalence of tooth wear increases with age and associated with socio-behavioral risk factors.

Objective: To evaluate the quality of observational studies on pelvic organ prolapse in China. Methods: The checklist of strengthening the reporting of observational studies in epidemiology (STROBE) statement was applied to evaluate the observational studies. The articles were searched in the SinoMed database using the terms: prolapse, uterine prolapse, cystocele, rectal prolapse and pelvic floor; limited to Chinese core journals in obstetrics and gynecology from January 1996 to December 2015. With two 10-year groups (1996-2005 and 2006-2015), the χ(2) test was used to evaluate inter-group differences. Results: (1) A total of 386 observational studies were selected, including 15.5%(60/386) of case-control studies, 80.6%(311/386) of cohort studies and 3.9% (15/386) of cross-sectional studies. (2) There were totally 22 items including 34 sub-items in the checklist. There were 17 sub-items (50.0%, 17/34) had a reporting ratio less than 50% in all of aticles, including: 1a (study's design) 3.9% (15/386), 6a (participants) 24.6% (95/386), 6b (matched studies) 0 (0/386), 9 (bias) 8.3% (32/386), 10 (study size) 3.9%, 11 (quantitative variables) 41.2% (159/386), 12b-12e (statistical methods in detail) 0-2.6% (10/386), 13a (numbers of individuals at each stage of study) 18.9% (73/386), 13b (reasons for non-participation at each stage) 18.9%, 13c (flow diagram) 0, 16b and 16c (results of category boundaries and relative risk) 9.6% (37/386) and 0, 19 (limitations) 31.6% (122/386), 22 (funding) 20.5% (79/386). (3) The quality of articles published in the two decades (1996-2005 and 2006-2015) were compared, and 38.2%(13/34) of sub-items had been significantly improved in the second 10-year (all P< 0.05). The improved items were as follows: 1b (integrity of abstract), 2 (background/rationale), 6a (participants), 7 (variables), 8 (data sources/measurement), 9 (bias), 11 (quantitative variables), 12a (statistical methods), 17 (other analyses), 18 (key results), 19 (limitations), 21 (generalisability), 22 (funding). Conclusions: The quality of observational studies on POP in China is suboptimal in half of evaluation items. However, the quality of articles published in the second 10-year have significantly improved.

Understanding forest carbon budget and dynamics for sustainable resource management and ecosystem functions requires quantification of above- and below-ground biomass at individual tree species and stand levels. In this study, a total of 122 trees (9-12 per species) were destructively sampled to determine above- and below-ground biomass of 12 tree species (Acer mandshuricum, Acer mono, Betula platyphylla, Carpinus cordata, Fraxinus mandshurica, Juglans mandshurica, Maackia amurensis, P. koraiensis, Populus ussuriensis, Quercus mongolica, Tilia amurensis and Ulmus japonica) in coniferous and broadleaved mixed forests of Northeastern China, an area of the largest natural forest in the country. Biomass allocation was examined and biomass models were developed using diameter as independent variable for individual tree species and all species combined. The results showed that the largest biomass allocation of all species combined was on stems (57.1%), followed by coarse root (21.3%), branch (18.7%), and foliage (2.9%). The log-transformed model was statistically significant for all biomass components, although predicting power was higher for species-specific models than for all species combined, general biomass models, and higher for stems, roots, above-ground biomass, and total tree biomass than for branch and foliage biomass. These findings supplement the previous studies on this forest type by additional sample trees, species and locations, and support biomass research on forest carbon budget and dynamics by management activities such as thinning and harvesting in the northeastern part of China.

The 12 May 2008 M7.9 Wenchuan earthquake in the People's Republic of China represented a unique opportunity for the international community to use commonly available GIS (Geographic Information System) tools, like Google Earth (GE), to rapidly evaluate and assess landslide hazards triggered by the destructive earthquake and its aftershocks. In order to map earthquake-triggered landslides, we provide details on the applicability and limitations of publicly available 3-day-post- and pre-earthquake imagery provided by GE from the FORMOSAT-2 (formerly ROCSAT-2; Republic of China Satellite 2). We interpreted landslides on the 8-m-resolution FORMOSAT-2 image by GE; as a result, 257 large landslides were mapped with the highest concentration along the Beichuan fault. An estimated density of 0.3 landslides/km2 represents a minimum bound on density given the resolution of available imagery; higher resolution data would have identified more landslides. This is a preliminary study, and further study is needed to understand the landslide characteristics in detail. Although it is best to obtain landslide locations and measurements from satellite imagery having high resolution, it was found that GE is an effective and rapid reconnaissance tool. ?? 2009 Springer-Verlag.

Malocclusion is a common oral disease affecting children with various reported prevalence rates. This meta-analysis aimed to determine the epidemiological characteristics of malocclusion among pre-schoolers in mainland China from 1988 to 2017. A total of 31 qualified papers describing 51,100 Chinese children aged 2-7 years were selected. The pooled malocclusion prevalence was 45.50% (95% confidence interval (CI): 38.08-52.81%) with 26.50% Class I (CI: 19.96-33.12%), 7.97% Class II (CI: 6.06-9.87%) and 12.60% Class III (CI: 9.45-15.68%) cases. The most common type of malocclusion was overbite (33.66%, CI: 27.66-39.67%), and the flush terminal type (47.10%, CI: 28.76-65.44%) was the most common in the terminal plane relationship. An increasing trend and wide variations across the country were observed. Additionally, there was no significant difference in malocclusion by gender (relative risk (RR) = 1.01, [0.96-1.06]) or urban/rural area (RR = 0.99, [0.82-1.20]). Although this study represents a narrow view of deciduous-dentition malocclusion in mainland China, the results provide sample evidence that can aid clinicians and policy makers towards early prevention and timely treatment.

Antimicrobial resistance (R) surveillance across Asia and especially in China has documented unique patterns and mechanisms. This 2011 study reports results for 2278 isolates from 12 hospitals in China (94-216 strains/site); most from bacteremia (20.4%), pneumonias (29.1%), or skin and skin structure infections (20.9%). Samples were tested by reference broth microdilution methods, interpreted by published susceptibility (S) breakpoints. The most common species were Staphylococcus aureus (343, 45.8% MRSA), Escherichia coli (EC; 288), Pseudomonas aeruginosa (PSA; 221), Klebsiella spp. (KSP; 208), acinetobacters (ACB; 178), enterobacters (155), Streptococcus pneumoniae (SPN; 154, 46.8% penicillin-S), and enterococci (ENT; 137). Among 849 Gram-positive (GP) cocci, linezolid, tigecycline (TIG), daptomycin, and vancomycin provided best antimicrobial coverage (≥99.7% S). Resistance patterns of concern were 0.3% VISA, 15.4% teicoplanin non-S coagulase-negative staphylococci, 1.5% vancomycin-R ENT (all Enterococcus faecium), 1.9% levofloxacin-R β-haemolytic streptococci, and 35.1 and 12.7% ceftriaxone-non-S rates for SPN and viridans group streptococci, respectively. For Gram-negative bacilli, R among Enterobacteriaceae was highest against β-lactams (extended spectrum β-lactamase-phenotype strains at 73.6 and 42.8% in EC and KSP, respectively; carbapenem-R was only 2.1-4.3% with KPC and IMP type enzymes detected in KSP). The widest spectrum agents were cefoperazone/sulbactam (79.5-86.1%), piperacillin/tazobactam (88.9-92.0%), TIG (98.6-100%), amikacin (AMK; 91.8-93.7%), and meropenem (95.7-97.1% S). PSA was most inhibited by AMK (90.5% S) and colistin (COL; 99.5%), with cefepime (67.9%) best among the tested β-lactams. Only COL (100% S) and TIG (MIC90, 2 μg/mL) showed significant potencies against ACB. In conclusion, R among pathogens from 12 Chinese hospitals illustrates several agents active against GP pathogens, but more serious R problems were noted among Enterobacteriaceae, PSA, and ACB. Combination treatment for the latter multidrug-R strains appears necessary, guided by local antibiograms and national surveillance results applying reference methods. © 2013.

Data from the New Canadian Children and Youth Study (NCCYS), a national study of immigrant children and youth in Canada, are used to examine the mental health salience of putatively universal determinants, as well as of immigration-specific factors. Universal factors (UF) include age, gender, family and neighbourhood characteristics. Migration-specific (MS) factors include ethnic background, acculturative stress, prejudice, and the impact of region of resettlement within Canada. In a sample of children from Hong Kong, the Philippines and Mainland China, the study examined the determinants of emotional problems (EP), and physical aggression (PA). A two-step regression analysis entered UF on step 1, and MS variables on step 2. Universal factors accounted for 12.1% of EP variance. Addition of MS variables increased explained variance to 15.6%. Significant UF predictors: parental depression, family dysfunction, and parent's education. Significant MS variables: country of origin, region of resettlement, resettlement stress, prejudice, and limited linguistic fluency. UF accounted for 6.3% of variance in PA scores. Adding migration-specific variables increased variance explained to 9.1%. UF: age, gender, parent's depression, family dysfunction. MS: country of origin, region of resettlement, resettlement stress, and parent's perception of prejudice. Net of the effect of factors affecting the mental health of most, if not all children, migration-specific variables contribute to understanding immigrant children's mental health.

2010-01-01

The 5-year and 10-year graft survivals for 186 deceased donor (DD) transplants performed at National University Health System (NUHS) were 79.9% and 58.4% respectively. 5-year and 10-year patient survivals for DD transplants performed at NUHS were 94.2% and 83.4%. The 5-year and 10-year graft survivals for 128 living donor (LD) transplants performed at NUHS were 90.2% and 72% respectively. 5-year and 10-year patient survivals for DD transplants performed at NUHS were 98.6% and 95.1%. The projected graft half lives were 14.6 and 20.6 years for DD and LD transplants respectively. These results compare favorably with the 10-year survival rates of 40% and 58% for DD and LD grafts reported by the United States Renal Data System (USRDS) in 2010. The younger age and the lower prevalence of diabetes and HLAmismatch in the DD and LD transplant study populations, in comparison to the USRDS population and perhaps better access and compliance to maintenance immunosuppression, could have contributed to these excellent outcomes. The 5-year and 10-year graft survivals for 162 transplants receiving what were likely deceased donor kidneys from China were 89.2% and 69.2% respectively. Although these survivals were apparently better than that for DD performed at NUHS, the advantage for China Tx disappeared when DD with primary non function or vascular thrombosis were excluded from analysis. The 5-year and 10-year patient survivals for 30 transplants receiving live non-related transplants from India were 82.3% and 60.1%. Both groups were considered to have received commercial transplants based on various aspects of history from the patients. Among those receiving China_Tx or India Tx, there were a disproportionate number of males and Chinese; and a significant proportion underwent pre-emptive transplant or transplant after only a short period of dialysis. Prevalence of post-transplant hepatitis B was significantly higher among China_Tx than their DD counterparts (7.7% vs. 1.2%, P = 0.005); likewise, post transplant hepatitis C was significantly higher for India_Tx than their LD counterparts (23.1% vs. 3.4%, P = 0.003). These results suggest that commercialization in transplant, results in inequities to access to transplantation and is associated with compromise in screening for infections among potential donors or in observing safety precautions during dialysis.

2011-01-01

University teachers in China are expected to suffer serious occupational stress due to the expanding enrollment in universities without a proportional increase in teacher resources and the fact that all promotions for university teachers are determined based on not only teaching but also the outcome of scientific research. This study was designed to assess the occupational stress among university teachers in China and clarify its risk factors. A cross-sectional study was performed in Liaoning Province, the centralized area of higher education in Northeast China. Eight universities (2 multidiscipline and 6 specialized) and 10% of academic staff each were randomly sampled. Questionnaires pertaining to occupational stress indicated by the Chinese Version Personal Strain Questionnaire (PSQ) and demographic characteristics, health status, work situations, and personal and social resources were distributed in October 2008. A total of 827 effective respondents (response rate 76.4%) became our participants. The average raw score of PSQ was 91.0 among the university teachers. General linear model analysis showed that the factors significantly associated with the PSQ score were, in standardized estimate (β) sequence, mental health, role overload, role insufficiency, social support, monthly income, role limitations due to physical problems, research finance and self-rated disease with adjustment for age and sex. We concluded that, in comparison to work-related factors and social support, mental health is a prominent risk factor for occupational stress in university teachers in China. Improvement of mental health and organizational climate should be considered to lessen the occupational stress of university teachers.

Hand, foot and mouth disease (HFMD) is a common illness in China that mainly affects infants and children. The objective of this study is to assess the economic cost and health-related quality of life associated with HFMD in China. A telephone survey of caregivers were conducted in 31 provinces across China. Caregivers of laboratory-confirmed HFMD patients who were registered in the national HFMD enhanced surveillance database during 2012-2013 were invited to participate in the survey. Total costs included direct medical costs (outpatient care, inpatient care and self-medication), direct non-medical costs (transportation, nutrition, accommodation and nursery), and indirect costs for lost income associated with caregiving. Health utility weights elicited using EuroQol EQ-5D-3L and EQ-Visual Analogue Scale (VAS) were used to calculate associated loss in quality adjusted life years (QALYs). The subjects comprised 1136 mild outpatients, 1124 mild inpatients, 1170 severe cases and 61 fatal cases. The mean total costs for mild outpatients, mild inpatients, severe cases and fatal cases were $201 (95%CI $187, $215), $1072 (95%CI $999, $1144), $3051 (95%CI $2905, $3197) and $2819 (95%CI $2068, $3571) respectively. The mean QALY losses per HFMD episode for mild outpatients, mild inpatients and severe cases were 3.6 (95%CI 3.4, 3,9), 6.9 (95%CI 6.4, 7.4) and 13.7 (95%CI 12.9, 14.5) per 1000 persons. Cases who were diagnosed with EV-A71 infection and had longer duration of illness were associated with higher total cost and QALY loss. HFMD poses a high economic and health burden in China. Our results provide economic and health utility data for cost-effectiveness analysis for HFMD vaccination in China.

It is unclear about the change and risk factors of depression among adolescent survivors after earthquake. This study aimed to explore the change of depression, and identify the predictive factors of depression among adolescent survivors after the 2008 Wenchuan earthquake in China. The depression among high school students at 6, 12 and 18 months after the Wenchuan earthquake were investigated. The Beck Depression Inventory (BDI) was used in this study to assess the severity of depression. Subjects included 548 student survivors in an affected high school. The rates of depression among the adolescent survivors at 6-, 12- and 18-month after the earthquake were 27.3%, 42.9% and 33.3%, respectively, for males, and 42.9%, 61.9% and 53.4%, respectively, for females. Depression symptoms, trauma-related self-injury, suicidal ideation and PTSD symptoms at the 6-month follow-up were significant predictive factors for depression at the 18-month time interval following the earthquake. This study highlights the need for considering disaster-related psychological sequela and risk factors of depression symptoms in the planning and implementation of mental health services. Long-term mental and psychological supports for victims of natural disasters are imperative.

We investigate the effect of Zn doping on the dielectricity and ferroelectricity of a series of polycrystalline Sr0.9-xZnxBa0.1TiO3 (0.0% ≤ x ≤ 5.0%) ceramics. It is surprisingly observed that the Zn doping will produce the multifold polar states, i.e., the Zn-doped ceramic will convert a reduced polar state into an enhanced polar state, and eventually into a stabilized polar state with increasing the doping level x. It is revealed that in the background of quantum fluctuations, the competition between the Zn-doping-induced lattice contraction and the Ba-doping-induced lattice expansion is responsible for both the reduced polar state and the enhanced polar state coming into being. Also, the addition of the antiferrodistortive effect, which is the antipolar interaction originating from the opposite tilted-TiO6 octahedra rotation, represents the core physics behind the stabilized polar state.

Commercial sex workers within the population of men who have sex with men (MSM) in China, known as 'money boys' (MBs), are perceived to be at higher risk for HIV and other sexually-transmissible infections (STIs). We conducted a systematic review and meta-analyses from peer-reviewed literature accessed in two English (PubMed and Embase) and three Chinese databases (CNKI, CQVIP, Wanfang data). A data synthesis exercise was carried out to determine the extent and patterns of behaviours and HIV/STI epidemics. Pooled estimates, with 95% confidence intervals, for each study variable were calculated. Thirty-two eligible articles (9 in English and 23 in Chinese) were identified. Our analysis indicated that Chinese MBs are generally young, currently employed, at low literacy levels and highly mobile. The prevalence of HIV, syphilis and co-infection among MBs were estimated to be 6.0% (4.2-8.5%), 12.4% (9.9-15.3%) and 2.2% (1.1-4.1%) over the period of 2004-2011. Level of condom use among MBs is generally higher than the broader MSM population (69.2% at last act, and 48.5% consistently over the past 6 months). One-third of the Chinese MBs identified themselves as bisexual and 8.7% (5.6-13.5%) are currently married to a female. Further, 40.9% (34.5-47.7%) of MBs participated in group sex in the past 12 months and 14.8% (10.6-20.3%) concurrently use illicit drugs. HIV/STI epidemics have affected Chinese MBs but the evidence suggests that the extent of infections is not greater than among other MSM in China.

Functional bowel disorders (FBDs) such as irritable bowel syndrome (IBS) impact on quality of life and health care resources. It is uncertain whether patients with functional digestive symptoms have similar characteristics in different populations. This population-based study assessed the prevalence and identified risk factors for these disorders in South-East China. Five communities were selected at random and invitations distributed to a representative sample (block randomization). Questionnaires were completely supervised by investigators. Demographic and medical data with FBD symptoms (Rome III criteria), psychological condition, life event stress, and quality of life were collected. Functional bowel disorder prevalence was 41.6% in 1999/2115 (94.5%) completed questionnaires: 9.9% functional constipation (FC), 6.8% bloating (FB), 6.5% diarrhea (FD), 5.9% IBS (IBS-D 47.1%, IBS-M 23.9%, IBS-C 12.8%, IBS-U 16.2%), and 12.6% unspecified. Similar numbers of men and women had FBDs or IBS (overall; 51.3% male vs 48.7% female, P=.796); however, there was female predominance in FC (62.1%, P<.001) and FB (58.5%, P=.038). FBDs were associated with greater anxiety, depression, life event stress, and a lower quality of life compared with those without symptoms (all, P<.0001). Logistic regression identified medical co-morbidity, anxiety/depression, and life event stress as independent risk factors for these disorders. Functional bowel disorders are as common in South China as in western populations. A similar number of men and women report FBDs and IBS. Only FC and FB are more prevalent in females. Independent risk factors associated with FBDs included physical and psychosocial stressors. © 2016 John Wiley & Sons Ltd.

In recent years, China's healthcare reforms and related studies have drawn particular global attention. The main objective of this study is to evaluate quantitatively the publication trends and collaboration performance of China in healthcare science and services (HSS) research. Scientometric methods and visualization technology were used to survey the growth and development trends of HSS research based on the Web of Science publications during the past 15 years. China's international publications on HSS research increased rapidly compared to those of the global HSS and Chinese scientific studies. Growth trends indicate that collaboration among countries, institutions and authors has also increased. China's leading partners were all developed countries, such as the US, the UK, Australia and Canada, which have contributed to the majority of the joint publications. The academic impact of publications involving partners from European and American countries was relatively higher than those involving partners from Asian countries. Prominent institutions were universities that could be primarily classified into two groups, namely, Mainland China on the one hand and Hong Kong universities and foreign universities on the other. The most prominent actors were elite institutions, such as Peking University, Fudan University, Chinese University of Hong Kong, University of Hong Kong. The papers published by the Chinese Ministry of Health had relatively high academic impact, whereas those published by Mainland China universities alone had a lower academic impact compared to foreign cooperation papers. Issues related to the Chinese healthcare reform, priority diseases (e.g., breast cancer, HIV/AIDS, tuberculosis, etc.), health systems performance, quality of life and measurement tools, aging problems and research methods have been the most popular HSS topics in China in recent years. Despite the extensive achievement of the Chinese HSS reforms and research, gaps and challenges remain to be addressed, including those related to health insurance and the effects of the evaluation of essential medicine systems, human resources training and allocation in the health sector, government hospitals reforms and health services systems remodeling. These findings could help scholars and decision-makers understand the current status and likely future trends of the Chinese HSS research, and help them select the most appropriate collaboration partners and policies.

In many countries the frequency of eating out has steadily increased over the last few decades, and this behavioris often associated with unhealthy dietary patterns. This study aimed to describe the levels of knowledge, attitude, and behaviors (KAB) related to eating out among university students. A cross-sectional study was conducted in the college town in Chongqing, China with a total of 1634 participants. The mean eating out related KAB scores were: knowledge 11.5 ± 2.9, attitude 17.0 ± 2.8, and behaviors 24.2 ± 4.8 (possible total scores: 20, 24, 40 respectively). As the level of knowledge increased, the percentage of highly satisfactory attitude and behaviors increased. Only 10% of the participants did not eat out for lunch and dinner during weekends in the last month. Gender, ethnicity, mother’s education, monthly boarding expenses, living place during the study, and the frequency of eating out for breakfast were statistically associated with the scores of KAB. In conclusion, Chinese junior students had poor knowledge of and behaviors towards eating out and ate out frequently. Educational interventionsto improve knowledge related eating out are needed in order to promote healthy eating out behaviors among Chinese university students. PMID:27420075

To investigate university students' knowledge, attitudes and practice (KAP) regarding vitamin D. The students were requested to answer a questionnaire related to vitamin D and sun exposure. The consumption frequency of foods rich in vitamin D was assessed. Additionally, the intake of vitamin D-containing supplements was recorded. A medical university in Nanjing, China. Five hundred and fifteen medical students were included. The highest rate of correct responses for the quiz was 68·0 %, while the lowest was 9·6 %. Most students lacked sun exposure because they did not want to get tanned; 82·7 % of students used some sun protection and sunscreen use was more popular in the female group. The consumption frequency of foods rich in vitamin D was low and 5·6 % of the students used vitamin D supplements. The students' knowledge on vitamin D was derived mainly from the media and health professionals. Most of the students were interested to know more about vitamin D. The present study suggested that medical students had little knowledge and unfavourable behaviours. They should get more health education through the media and health professionals. It is advisable to increase their consumption of foods rich in vitamin D.

A brief introduction to China's family planning programme.

PubMed

Shen, G

1984-08-01

China's family planning program is described in reference to its goals, approaches, and achievements. Between 1949-83, China's population increased from 541 million to 1,024,950,000. The population has a young age structure, and the median age is 22.9 years. 80% of the population is rural, and 90% of the population lives in the southeastern region of the country. In view of this demographic situation, the government recognizes the need to control population growth. China's goals for the year 2000 are to increase industrial and agricultural input by 400% and to keep population size below 1.2 billion in order to ensure that per capita income increases. In accordance with these goals, the government, in 1979, began advocating a 1-child policy. To ensure the survival of single children, the government also launched a program to upgrade maternal and child health (MCH). In some rural areas and among certain minority groups, the 1-child restriction is not applied. Family size goals will vary with time. These variations will reflect the need to maintain a balance between economic growth and population growth. A variety of incentives are used to promote the 1-child family. For example, single children receive medical and educational benefits, and in some rural areas, the parents of single children can obtain additional land contracts. Economic disincentives are also used. The government seeks to obtain compliance with the policy primarily through educating the public about the consequences of uncontrolled population growth. All channels of the mass media are used to deliver the messages, and the publicity campaign is especially intensive in rural areas. A comprehensive plan to provided family planning and population education for middle school students is currently being implemented. Each local area develops its own fertility control plan. This plan is then incorporated into the nation's overall plan and the overall plan is implemented from above. Family planning workers bring free contraceptives directly to the people, and family planning motivators are found in almost all villages, neighborhood committees, factories, and military units. As a result of these efforts, China made great strides in controlling population growth and improving MCH during the last decade. The birth rate declined from 27.93 to 18.62, and the total fertility rate declined from 4.01 to 2.48. 124 million couples were practicing contraception by the end of 1983. 41% used IUDs, 37.4% relied on tubal ligation, 12.9% relied on vasectomy, 5.1% on oral contraceptives, and 1% on other methods. The quality of maternal and child care also improved. 92.7% of all deliveries are now performed by trained midwifes. Infant and maternal mortality rates declined considerablely in recent years. Currently the respective rates are 35.68/1000 live births and 0.5/1000 live births. In 1983 alone, the gross national agricultural and industrial output increased by 46.1%. Since 1979 per capita income increased annually by 18.3% among rural residents and by 10.7% among urban workers. China controls and operates its own population program, but in recent years, it increased its cooperation with UN Fund for Population Activities, other UN agencies, and nongovernment agencies. China recently completed its 3rd national census, and demographic research institutes have been established in 10 universities.

Building biophysics in mid-century China: the University of Science and Technology of China.

Luk, Yi Lai Christine

2015-01-01

Biophysics has been either an independent discipline or an element of another discipline in the United States, but it has always been recognized as a stand-alone discipline in the People's Republic of China (PRC) since 1949. To inquire into this apparent divergence, this paper investigates the formational history of biophysics in China by examining the early institutional history of one of the best-known and prestigious science and technology universities in the PRC, the University of Science and Technology of China (USTC). By showing how the university and its biophysics program co-evolved with national priorities from the school's founding in 1958 to the eve of the Cultural Revolution in 1966, the purpose of this paper is to assess the development of a scientific discipline in the context of national demands and institutional politics. Specific materials for analysis include the school's admission policies, curricula, students' dissertations, and research program. To further contextualize the institutional setting of Chinese biophysics, this paper begins with a general history of proto-biophysical institutions in China during the Nationalist-Communist transitional years. This paper could be of interest to historians wanting to know more about the origin of the biophysics profession in China, and in particular how research areas that constitute biophysics changed in tandem with socio-political contingencies.

In this paper, the development process, present situations, causes of improvement, and trends of higher education of environmental engineering in China are discussed. Several education modes in environmental engineering in China are also presented. The development process can be divided into three stages: the beginning stage, the expansion stage, and the modification stage. The 1970's and early 1980's wake of environmental consciousness and serious pollution situation in China resulted in about 20 universities setting up an environmental engineering specialty. The late 1980's and middle 1990's job opportunities for undergraduates in China resulted in many universities' creation of the environmental engineeringmore » specialty from specialties such as geography, geology, hydrology, mining engineering, and mineral separation engineering where job opportunities were stagnant. At present, adjustment and improvement of environmental engineering education are urgently required because of the excessive increase of undergraduate number, change of job opportunities and implementation of five-work-day system in China. Other problems include how to determine the ratio of social science courses to engineering science courses, how to determine the relationship of fundamental and applied courses, and how to determine the specialized direction. Hunan University, as a typical university conferring an accredited Bachelor degree in Environmental Engineering in four academic years in China, has been improving the instruction schedule for undergraduate education in environmental engineering. The curricula of the three phases for undergraduates of environmental engineering specialty at Hunan University are presented as a case study.« less

This study investigated the effects of sedentary occupations on type 2 diabetes and hypertension in different ethnic groups in North West China. All subjects were civil servants who received health examinations in the First Affiliated Hospital of Xinjiang Medical University from October 2010 to March 2014. A total of 46,612 participants (39,120 Han, 4148 Uygur, 2098 Hui, 877 Kazak and 369 other ethnicities) completed the examination. Overall, 16.4% of the Han, 14.4% of the Uygur, 15.9% of the Hui, 20.6% of the Kazak and 16.0% of other ethnicities had hypertension. Diabetes was found in 7.6% of the Han, 8.5% of the Uygur, 9.2% of the Hui, 7.4% of the Kazak, and 3.3% of other ethnicities. There was a significant difference between men and women in the prevalence of diabetes (4.3% in women vs 9.7% in men, p < 0.001) and hypertension (9.7% in women vs 21.0% in men, p < 0.001). Our results indicate that both diabetes and hypertension are highly prevalent in individuals with sedentary occupations.

Psychological distress and suicidal behavior are important mental health problems among university students and warrant research to inform strategies for effective prevention in this young population. The present study aimed to assess psychological distress and suicidal behavior and to unravel their associations among university students. A total of 5972 undergraduate students, randomly selected from six universities in central China, comprised the sample. The Chinese version of the Symptom Checklist-90-revised (SCL-90-R) was used to assess various psychological symptoms. Logistic regression analysis was used to examine the relationship between psychological distress and risk for suicidal behavior. 40.7% of the university students reported positive in a least one of the 9 psychological symptom dimensions assessed by the SCL-90-R. 7.6% of the students reported suicidal behavior in the previous twelve months. The risk of suicidal behavior was significantly associated with psychological symptoms of all types, but there were notable differences by sex. For male students, depression and phobic anxiety increased the risk of suicidal behavior. Meanwhile, depression and obsessive-compulsiveness were positively associated with suicidal behavior in female students. Furthermore, increasing risk of suicidal behavior was associated with increasing positive symptom total (PST) score and a statistically significant trend was observed. Data collected from a cross-sectional survey does not allow any examination of causal inference. Psychological distress and suicidal behavior were both common among university students; and psychological distress was highly associated with suicidal behavior. The findings underscore the importance of mental health care for university students. Copyright © 2017 Elsevier B.V. All rights reserved.

Currently, research in sexual behavior and awareness in female Chinese college students (FCCSs) is limited, particularly regarding the difference and the influencing factors between students from rural areas and urban areas. To fill the gap in available data, a cross-sectional study using anonymous questionnaires was conducted among 3193 female students from six universities located in Beijing, Shanghai, and Guangzhou, China, from February to June, 2013. Of the 2669 respondents, 20.6% and 20.9% of the students from urban and rural areas, respectively, reported being sexually experienced. The proportion of students who received safe-sex education prior to entering university from rural areas (22.4%, 134/598) was lower (P < 0.0001) than the proportion from urban areas (41.8%, 865/2071). Sexual behavior has become increasingly common among FCCSs, including high-risk sexual behavior such as unprotected commercial sex. However, knowledge concerning human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) transmission and the risks is insufficient, particularly for those from rural areas, which is a challenge for HIV/AIDS control in China. The Chinese government should establish more specific HIV/AIDS prevention policies for Chinese young women, strengthen sex education, and continue to perform relevant research. PMID:28101513

The unnatural death investigation in China seems vague to the world. Shanghai is one of the largest city located in Yangtze River Delta in the East China. This study is committed to lift the veil of unnatural death investigation and describe the epitome of China's unnatural deaths. Based on the 7302 forensic report archives from 1990 to 1999 in Shanghai Public Security Bureau, statistics were carried out in 5 areas according to the manner of death. In 3502 accidental deaths, there was a rapid increase during the 1990s, and 71.6% were involved in traffic accidents whose major cause of death was head and neck injuries. The first 3 causes of death in nontraffic accidents (994) were head and neck injuries (42.8%), poisoning (11.8%), and drowning (9.0%). In 2456 homicides, sharp force injury (36.7%), blunt force injury (35.8%), and manual strangulation (12.9%) were the first 3 causes of death. In 563 suicides, drug/chemical intoxication (40.1%), hanging (23.4%), and injuries because of fall from height (11.4%) were the 3 leading causes of death, especially pesticides ingestion. The causes of natural deaths were diseases mainly in circulatory system (23.1%), central nervous system (12.8%), and respiratory system (6.4%). However, the cause of death remained undetermined in 500 victims. Childhood fatalities were different. The victims of accidents and homicides were nearly equal, and the main cause of homicide was manual strangulation. Besides, 1997 was the landmark year when drug abuse began to emerge in Shanghai.

Objectives. The study provided data to demonstrate the characteristics of type 2 diabetes (T2D) with ketosis in rural parts of south-west border of China in order to help health professionals with optimizing diabetic care. Methods. All hospitalized adult diabetic patients consecutively between January 2011 and July 2015 in Baoshan People's Hospital, Yunnan province of China, were evaluated. T2D with ketosis, ordinary T2D (without ketosis), and type 1 diabetes (T1D) patients were analyzed according to the clinical and biochemical parameters and chronic complications in these subjects. Results. The prevalence of T2D with ketosis was 12% in the whole study subjects. Overweight and obese patients were predominant (49.1%) in T2D patients with ketosis. The mean HbA1c (13.3 ± 3.1%, P = 0.01), fasting plasma glucose (16.9 ± 6 mmol/L, P < 0.0001), and plasma triglyceride (4.0 ± 4.0 mmol/L, P < 0.0001) in T2D patients with ketosis were significantly higher than ordinary T2D patients without ketosis. Infections were the most common inducements in T2D patients with ketosis. Chronic complications including peripheral neuropathy (34.9%), retinopathy (12.7%), diabetic foot (18.1%), and persistent microalbuminuria (11.7%) were common in T2D patients with ketosis. Conclusions. This study indicated the poor glycemic control in diabetic patients in rural areas of south-west part of China. More efforts were urgently required to popularize public health education and improve medical quality in diabetic treatment in these regions. PMID:26881259

ABSTRACT The novel low-pathogenic avian influenza A H7N9 viruses (LPAI H7N9 viruses) have been a threat to public health since their emergence in 2013 because of the high rates of mortality and morbidity that they cause. Recently, highly pathogenic variants of these avian influenza A H7N9 viruses (HPAI H7N9 viruses) have emerged and caused human infections and outbreaks among poultry in mainland China. However, it is still unclear how the HPAI H7N9 virus was generated and how it evolved and spread in China. Here, we show that the ancestor virus of the HPAI H7N9 viruses originated in the Yangtze River Delta region and spread southward to the Pearl River Delta region, possibly through live poultry trade. After introduction into the Pearl River Delta region, the origin LPAI H7N9 virus acquired four amino acid insertions in the hemagglutinin (HA) protein cleavage site and mutated into the HPAI H7N9 virus in late May 2016. Afterward, the HPAI H7N9 viruses further reassorted with LPAI H7N9 or H9N2 viruses locally and generated multiple different genotypes. As of 14 July 2017, the HPAI H7N9 viruses had spread from Guangdong Province to at least 12 other provinces. The rapid geographical expansion and genetic evolution of the HPAI H7N9 viruses pose a great challenge not only to public health but also to poultry production. Effective control measures, including enhanced surveillance, are therefore urgently needed. IMPORTANCE The LPAI H7N9 virus has caused five outbreak waves in humans and was recently reported to have mutated into highly pathogenic variants. It is unknown how the HPAI H7N9 virus originated, evolved, and disseminated in China. In this study, we comprehensively analyzed the sequences of HPAI H7N9 viruses from 28 human and 21 environmental samples covering eight provinces in China that were taken from November 2016 to June 2017. The results show that the ancestor virus of the HPAI H7N9 viruses originated in the Yangtze River Delta region. However, the insertion of four amino acids into the HA protein cleavage site of an LPAI H7N9 virus occurred in late May 2016 in the Pearl River Delta region. The mutated HPAI H7N9 virus further reassorted with LPAI H7N9 or H9N2 viruses that were cocirculating in poultry. Considering the rapid geographical expansion of the HPAI H7N9 viruses, effective control measures are urgently needed. PMID:28956760

Childhood personality is a rapidly growing area of investigation within individual differences research. One understudied topic is the universality of the hierarchical structure of childhood personality. In the present investigation, parents rated the personality characteristics of 3,751 children from 5 countries and 4 age groups. The hierarchical structure of childhood personality was examined for 1-, 2-, 3-, 4-, and 5-factor models across country (Canada, China, Greece, Russia, and the United States) and age group (3-5, 6-8, 9-11, and 12-14 years of age). Many similarities were noted across both country and age. The Five-Factor Model was salient beginning in early childhood (ages 3-5). Deviations across groups and from adult findings are noted, including the prominent role of antagonism in childhood personality and the high covariation between Conscientiousness and intellect. Future directions, including the need for more explicit attempts to merge temperament and personality models, are discussed. © 2011 The Authors.

To describe the differences in diet intake frequency of adults in 10 areas surveyed by China Kadoorie Biobank (CKB) project. CKB project recruited voluntary residents aged 30-79 years from 5 urban areas and 5 rural areas in China. The baseline survey was conducted among 512 891 eligible subjects during 2004-2008. The intake frequencies of 12 food groups were assessed through in-person interviews and analyzed. The results were adjusted for age and sex structure of the study population. Rice was the main cereal consumed every day in urban areas (99.0%) and rural areas (99.9%) in southern China, while wheat was the main cereal consumed every day in rural areas (99.0%) and Qingdao (88.4%) in northern China. Most subjects in Henan (98.8%) consumed other staple food every day. The lowest proportion of daily intake of fresh vegetables was observed in Gansu (74.0%) . In both southern and northern areas, urban subjects had higher proportions of daily intakes of fresh fruits, preserved vegetables, and meat than rural subjects. Similar results were found when comparing the proportions of intakes of poultry and fish/seafood at least 1 day every week. Contrast to southern China (urban: 6.5%, rural: 6.9%) , the proportions of daily intake of fresh eggs were higher in both urban areas (37.1%) and rural areas (14.6%) in northern China. The highest proportions of daily intake of soybean products and dairy products were observed in Harbin (10.0%) and Qingdao (34.3%). The intake of cereal, fresh eggs and soybean products differed between the south and the north of China. The intake of meat, poultry, fish/seafood, fresh fruits, preserved vegetables and dairy products varied considerably between urban areas and rural areas.

There has been no nationwide investigation into anesthesia quality and patient safety in China. The authors surveyed Chinese anesthesiologists about anesthesia quality by sending a survey to all anesthesiologist members of the New Youth Anesthesia Forum via WeChat. The respondents could choose to use a mobile device or desktop to complete the survey. The overall response rate was 43%. Intraoperative monitoring: 77.9% of respondents reported that electrocardiogram monitoring was routinely applied for all patients; only 55% of the respondents reported that they routinely used end-tidal carbon dioxide monitoring for their patients under general anesthesia. 10.3% of respondents admitted that they had at least one wrong medicine administration in the past 3 months; 12.4% reported that they had at least one case of cardiac arrest in the past year. This is the first anesthesia quality survey in China. The findings revealed potential anesthesia safety issues in China.

Background Lifestyle modification is one of the most cost-effective strategies in self-management and secondary prevention of chronic obstructive pulmonary disease (COPD). However, the prevalence of healthy lifestyle behaviors in COPD patients in China remains unclear. The objective of this study was to examine the rates of healthy lifestyle behaviors including smoking cessation, regular exercise, and healthy diet in community population with COPD in China. Methods We recruited 46,285 individuals aged 35–70 years from 115 urban and rural communities in 12 provinces of China from 2005 to 2009. We recorded the smoking status, physical activity intensity, and quality of diet for all spirometry-diagnosed COPD patients by standardized questionnaires. Results Among 3,690 individuals with COPD, 18.2% (95% confidence interval [CI], 13.0–24.9) quitted smoking, 27.1% (95% CI, 24.7–29.7) exercised often, and 34.8% (95% CI, 31.8–38.0) ate high-quality diet. More than half of the individuals followed one or less key healthy lifestyle, and only 8.4% (95% CI, 7.0–10.0) followed all of the three healthy behaviors. Urban residents had significant higher rates of smoking cessation (23.5% [95% CI, 17.3–31.1] vs 14.4% [95% CI, 9.9–20.5], p=0.0008), regular exercise (45.6% [95% CI, 42.4–48.8] vs 14.0% [95% CI, 12.1–16.2], p<0.0001), and healthy diet (38.5% [95% CI, 35.5–41.6] vs 32.2% [95% CI, 29.2–35.4], p=0.0013) than rural residents. Age, sex, education level, body mass index, respiratory symptoms, and family income were associated with healthy living, and the strength of associations varied between urban and rural areas. Conclusion There is a large gap between the anticipated rate and the real participation in healthy lifestyle behaviors in Chinese adults with COPD, especially in rural communities. Simple and effective strategies are warranted to improve patients’ lifestyle in China. PMID:29180861

This study aimed to estimate the pooled prevalence of suicidal ideation among Chinese elderly aged ≥ 60 years. Two reviewers independently searched the potentially relevant studies through electronic database (PubMed-Medline, Embase, Wanfang Data, Chinese National Knowledge Infrastructure and Chongqing VIP) using key terms 'suicid', 'suicidal ideation' combined with 'aged', 'elderly' and 'old people'. All selected studies should meet the eligibility criteria in this study. Chi-square based Q test and I(2) statistic assessed the heterogeneity. Forest plots were used to display results graphically. Potential publication bias was assessed by the funnel plot and Begg's test. Prevalence rate was meta-analysed. In total, 11 studies were included with 11,526 subjects. The prevalence of suicidal ideation among Chinese elderly ranged from 2.2% to 21.5%. The pooled prevalence of all 11 studies was 11.5% (95% CI: 8.3%-14.8%). Subgroup analyses showed the prevalence for males was 11.0%, and for the females was 15.6%. In three subgroups for age, 60-69, 70-79 and ≥ 80, the prevalence was 9.1%, 12.1% and 18.9% respectively. A slightly higher prevalence in rural areas was calculated than in urban (14.7% vs. 11.8%). In mainland China, the prevalence was 12.6%. And in Taiwan and Hongkong, the pooled prevalence was 9.2%. The prevalence of suicidal ideation was relatively high among elderly in China, and it should attract enough attention. Copyright © 2014 Elsevier Inc. All rights reserved.

Chemical mass balance (CMB) modeling and radiocarbon measurements were combined to evaluate the sources of carbonaceous fine particulate matter (PM 2.5 ) in Shenzhen, China during and after the 2011 summer Universiade games when air pollution control measurements were implemented to achieve air quality targets. Ambient PM 2.5 filter samples were collected daily at two sampling sites (Peking University Shenzhen campus and Longgang) over 24 consecutive days, covering the controlled and uncontrolled periods. During the controlled period, the average PM 2.5 concentration was less than half of what it was after the controls were lifted. Organic carbon (OC), organic molecular markers (e.g., levoglucosan, hopanes, polycyclic aromatic hydrocarbons), and secondary organic carbon (SOC) tracers were all significantly lower during the controlled period. After pollution controls ended, at Peking University, OC source contributions included gasoline and diesel engines (24%), coal combustion (6%), biomass burning (12.2%), vegetative detritus (2%), biogenic SOC (from isoprene, α-pinene, and β-caryophyllene; 7.1%), aromatic SOC (23%), and other sources not included in the model (25%). At Longgang after the controls ended, similar source contributions were observed: gasoline and diesel engines (23%), coal combustion (7%), biomass burning (17.7%), vegetative detritus (1%), biogenic SOC (from isoprene, α-pinene, and β-caryophyllene; 5.3%), aromatic SOC (13%), and other sources (33%). The contributions of the following sources were smaller during the pollution controls: biogenic SOC (by a factor of 10-16), aromatic SOC (4-12), coal combustion (1.5-6.8), and biomass burning (2.3-4.9). CMB model results and radiocarbon measurements both indicated that fossil carbon dominated over modern carbon, regardless of pollution controls. However, the CMB model needs further improvement to apportion contemporary carbon (i.e. biomass burning, biogenic SOC) in this region. This work defines the major contributors to carbonaceous PM 2.5 in Shenzhen and demonstrates that control measures for primary emissions could significantly reduce secondary organic aerosol (SOA) formation.

This is a part of the study of AME survey-003, aiming to understand the motivation and attractiveness of a career in medicine in China. The surveys were conducted on DXY platform with 3,564 medical professionals during October 26 to November 20; on Sojump platform with 1,587 medical professionals during October 28 to December 14, and 443 non-medical professionals during November 15 to December, all in 2015. Similar to our previous result, the not regretted participants vs. regretted participants (N/Y) ratio was 1.1 (P<0.01), and there was no significant difference in N/Y ratio between male and female medical professionals. Medical professionals working in class-IIIA hospitals, small township hospitals, or primary care clinics had a relatively higher job satisfaction than those in hospitals of other classes, while lecturer-level attending doctors (zhuzhi yishi) had a relatively lower job satisfaction than doctors of other grades. A large portion of respondents who replied they regretted entered medical profession said they would still like to be in this profession if they could be in their preferred hospital class and specialty. Public health and basic science research staff, anesthesiologists, oncologists had a relatively higher job satisfaction, while accident and emergency physicians, nurses, and pediatricians had a relatively lower job satisfaction. Medical professionals in Yunnan and Gansu ranked consistently high in job satisfaction than other provinces; despite they were not in the economically advanced regions in China. Similar to our previous result, the majority of the participants favored China to open up medical market to qualified foreign medical organizations to take part in fair competition, as well as favor the government to support regulated private hospitals. Pooled data of 7,508 medical professionals with data from AME survey-003 A1 included showed medicine was the top career choice among medical professionals’ children (104/508, 20.5%), followed by finance and economics (74/508, 14.4%), and then electronic engineering or computer science (67/508, 13.2%). Among the 443 non-medical professionals, 122 have children who are attending university or have graduated, 12 (9.8%, 12/122) of them are pursuing a career in medicine. For the 100 non-medical professional parents whose children did not study medicine and if a choice could be given to them to start again, 60 parents (54.5%) replied they would support their children to study medicine. Our results consistently show medicine remained an attractive profession in China. PMID:26981459

This paper uses case studies to focus on distance learning in developing countries as an enabler for economic development and poverty reduction. To provide perspective, we first review the history of telecottages, local technology-equipped facilities to foster community-based learning, which have evolved into "telecenters" or "Community Learning Centers" (CLCs). Second, we describe extensive site visits to CLCs in impoverished portions of China and Mexico, the centers operated by premier universities in each respective country. These CLCs constitute the core of new emerging systems of distance education, and their newness poses challenges and opportunities, which are discussed. Finally, we offer 12 points to develop further the concept and reality of distance learning in support of economic development.

Rapid Asian industrialization has led to increased downwind atmospheric nitrogen deposition threatening the marine environment. We present an analysis of the sources and processes controlling atmospheric nitrogen deposition to the northwestern Pacific, using the GEOS-Chem global chemistry model and its adjoint model at 1/2° × 2/3° horizontal resolution over East Asia and its adjacent oceans. We focus our analyses on the marginal seas: the Yellow Sea and the South China Sea. Asian nitrogen emissions in the model are 28.6 Tg N a-1 as NH3 and 15.7 Tg N a-1 as NOx. China has the largest sources with 12.8 Tg N a-1 as NH3 and 7.9 Tg N a-1 as NOx; the high-NH3 emissions reflect its intensive agricultural activities. We find Asian NH3 emissions are a factor of 3 higher in summer than winter. The model simulation for 2008-2010 is evaluated with NH3 and NO2 column observations from satellite instruments, and wet deposition flux measurements from surface monitoring sites. Simulated atmospheric nitrogen deposition to the northwestern Pacific ranges 0.8-20 kg N ha-1 a-1, decreasing rapidly downwind of the Asian continent. Deposition fluxes average 11.9 kg N ha-1 a-1 (5.0 as reduced nitrogen NHx and 6.9 as oxidized nitrogen NOy) to the Yellow Sea, and 5.6 kg N ha-1 a-1 (2.5 as NHx and 3.1 as NOy) to the South China Sea. Nitrogen sources over the ocean (ship NOx and oceanic NH3) have little contribution to deposition over the Yellow Sea, about 7 % over the South China Sea, and become important (greater than 30 %) further downwind. We find that the seasonality of nitrogen deposition to the northwestern Pacific is determined by variations in meteorology largely controlled by the East Asian monsoon and in nitrogen emissions. The model adjoint further estimates that nitrogen deposition to the Yellow Sea originates from sources over China (92 % contribution) and the Korean peninsula (7 %), and by sectors from fertilizer use (24 %), power plants (22 %), and transportation (18 %). Deposition to the South China Sea shows source contribution from mainland China (66 %), Taiwan (20 %), and the rest (14 %) from the southeast Asian countries and oceanic NH3 emissions. The adjoint analyses also indicate that reducing Asian NH3 emissions would increase NOy dry deposition to the Yellow Sea (28 % offset annually), limiting the effectiveness of NH3 emission controls on reducing nitrogen deposition to the Yellow Sea.

Professor Hu Huanyong died of an illness on April 30, 1998, in Shanghai, China. The professor was a forefather of modern Chinese demography and the founder of China's population geography. He drew the "Aihui-Tengchong Line," which was known internationally as the "Hu Line," in 1934; the line marked a striking difference in the distribution of China's population. He was born in 1901, in Yixing, Jiangsu Province. He studied literature, history, and geography at Nanjing Normal School (later named the Southeast University of China); he continued his education at the University of Paris from 1926 to 1928. Upon his return to China, he began teaching at the Nanjing Central University and was later appointed dean of the Department of Geography and president of the China Geographical Association. During this time, he wrote "Distribution of China's Population," a paper in which he drew China's first population density contour chart based on the 1933 national census data by county; this produced the "Hu Line." The professor began teaching at East-China Normal University in Shanghai in 1953; in 1957, he became director of the research office of population geography (which he helped to establish), the first demographic research institution in China. In 1958, he focused on the population geography of Jiangsu Province. In 1983, the office expanded to become a population research institute; Professor Hu became its president. During the 1980s, he described a geographic division of China's population based on differences in population density, ecological environment, socioeconomic conditions, and historical development. This resulted in 8 regions: 1) the lower parts of the Yellow River region; 2) the Liaoning-Jilin-Heilongjiang region; 3) the middle and lower parts of the Yangtze River region; 4) the southeast coastal region; 5) the Shanxi-Shaanxi-Gansu-Ningxia region; 6) the Sichuan-Guizhou-Yunnan region; 7) the Inner Mongolia-Xinjiang region; and 8) the Qinghai-Tibet region. This provided the basis for Chinese demographic policy-making and planning.

Sulfur dioxide residues in 20 kinds of products collected from 23 provinces of China (Jilin, Beijing, Shanxi, Shandong, Henan, Hebei, Jiangsu, Anhui, Shanghai, Zhejiang, Fujian, Guangdong, Guangxi, Yunnan, Guizhou, Hunan, Hubei, Chongqing, Sichuan, Gansu, Neimenggu, Xinjiang and Hainan) were analysed, and a health risk assessment was performed. The detection rates of sulfur dioxide residues in fresh vegetables, fresh fruits, dried vegetables and dried fruits were 11.1-95.9%, 12.6-92.3%, 70.3-80.0% and 26.0-100.0%, respectively; the mean concentrations of residues were 2.7-120.8, 3.8-35.7, 26.9-99.1 and 12.0-1120.4 mg kg -1 , respectively. The results indicated that fresh vegetables and dried products are critical products; the daily intakes (EDIs) for children were higher than others; the hazard indexes (HI) for four groups were 0.019-0.033, 0.001-0.005, 0.007-0.016 and 0.002-0.005 at P50, respectively. But the HI was more than 1 at P99 by intake dried fruits and vegetables. Although the risk for consumers was acceptable on the whole, children were the most vulnerable group. Uncertainty and sensitivity analyses indicated that the level of sulfur dioxide residues was the most influential variable in this model. Thus, continuous monitoring and stricter regulation of sulfites using are recommended in China.

Objective To estimate the health-related economic costs attributable to smoking in China for persons aged 35 and older in 2003 and in 2008 and to compare these costs with the respective results from 2000. Methods A prevalence-based, disease-specific approach was used to estimate smoking-attributable direct and indirect economic costs. The primary data source was the 2003 and 2008 China National Health Services Survey, which contains individual participant’s smoking status, healthcare utilization, and expenditures. Results The total economic cost of smoking in China amounted to $17.1 billion in 2003 and $28.9 billion in 2008 (both measured in 2008 constant US dollars). Direct smoking-attributable healthcare costs in 2003 and 2008 were $4.2 billion and $6.2 billion, respectively. Indirect economic costs in 2003 and 2008 were $12.9 billion and $22.7 billion, respectively. Compared to 2000, the direct costs of smoking rose by 72% in 2003 and 154% in 2008, while the indirect costs of smoking rose by 170% in 2003 and 376% in 2008. Conclusion The economic burden of cigarette smoking has increased substantially in China during the past decade and is expected to continue to increase as the national economy and the price of healthcare services grow. Stronger intervention measures against smoking should be taken without delay to reduce the health and financial losses caused by smoking. PMID:21339491

OBJECTIVE To investigate the geographic variation in diabetes prevalence and detection in China. RESEARCH DESIGN AND METHODS Self-report and biomedical data were collected from 98,058 adults aged ≥18 years (90.5% response) from 162 areas spanning mainland China. Diabetes status was assessed using American Diabetes Association criteria. Among those with diabetes, detection was defined by prior diagnosis. Choropleth maps were used to visually assess geographical variation in each outcome at the provincial level. The odds of each outcome were assessed using multilevel logistic regression, with adjustment for person- and area-level characteristics. RESULTS Geographic visualization at the provincial level indicated widespread variation in diabetes prevalence and detection across China. Regional prevalence adjusted for age, sex, and urban/rural socioeconomic circumstances (SECs) ranged from 8.3% (95% CI 7.2%, 9.7%) in the northeast to 12.7% (11.1%, 14.6%) in the north. A clear negative gradient in diabetes prevalence was observed from 13.1% (12.0%, 14.4%) in the urban high-SEC to 8.7% (7.8%, 9.6%) in rural low-SEC counties/districts. Adjusting for health literacy and other person-level characteristics only partially attenuated these geographic variations. Only one-third of participants living with diabetes had been previously diagnosed, but this also varied substantively by geography. Regional detection adjusted for age, sex, and urban/rural SEC, for example, spanned from 40.4% (34.9%, 46.3%) in the north to 15.6% (11.7%, 20.5%) in the southwest. Compared with detection of 40.8% (37.3%, 44.4%) in urban high-SEC counties, detection was poorest among rural low-SEC counties at just 20.5% (17.7%, 23.7%). Person-level characteristics did not fully account for these geographic variations in diabetes detection. CONCLUSIONS Strategies for addressing diabetes risk and improving detection require geographical targeting. PMID:25352654

Experimental study of the effect of polyanionic cellulose on process of filtrate loss of low-solids drilling fluid Ping Yang 1,2, Min-hui Wu2, Xue-wen Zhu2, Tao Deng2, Xue-qing Sun2 1. Key Laboratory of Geotechnical and Underground Engineering of Ministry of Education, Tongji University, Shanghai 200092,China 2. Department of Geotechnical Engineering,Tongji University,Shanghai 200092,China Abstract The process of filtrate loss of low-solids drilling fluid was tested by changing the polyanionic cellulose content in low-solids drilling fluid. The effect of polyanionic cellulose on process of filtrate loss of low-solids drilling fluid was analyzed. The test results showed that when time of filtration is same, the volume of filtrate loss decreases linearly with increasing polyanionic cellulose content. When polyanionic cellulose content is same, the rate of filtrate loss decreases nonlinearly with increasing time and the rate of filtrate loss will reach a stable value.The volume of filtrate loss in 7 to 8 minutes can reaches half of the total volume of filtrate loss. At the same time, the rate of filtrate loss of drilling fluid decreases nonlinearly with increasing viscosity.When the apparent viscosity is between 3.5~4.15 MPa.s, decrease speed of rate of filtrate loss of drilling fluid is quick. The results are helpful for characteristics evaluation of filtrate loss of drilling fluid and control of filtrate loss.

Enterovirus genotypes causing hand foot and mouth disease in Shanghai, China: a molecular epidemiological analysis

PubMed Central

2013-01-01

Background A rapid expansion of hand, foot, and mouth disease (HFMD) outbreaks has occurred and caused deaths in China in recent years, but little is known about the other etiologic agents except enterovirus 71 (EV71) and coxsackievirus A 16 (CA16). The objective of this study is to determine the genotype compositions of enterovirus causing HFMD in Shanghai and identify any associations between enterovirus types and clinical manifestations. Methods Stool specimens were collected from patients hospitalized for treatment of HFMD, from May 2010 to April 2011. Enterovirus was detected by reverse transcription PCR and directly genotyped by sequencing the PCR products. Phylogenetic analysis was based on the VP1 partial gene. Results Of 290 specimens, 277 (95.5%) tested positive for enterovirus. The major genotypes were EV71 (63.8%), CA10 (9.0%), CA6 (8.3%), CA16 (6.9%), CA12 (2.4%), and CA4 (1.4%). The EV71 strains belonged to the C4a subtype and CA16 belonged to the B subtype. CA6 was closely related to strains detected in Japan, Taiwan and China, and CA10, CA12 and CA4 were phylogenetically similar to other strains circulating in China. Mean hospital stays and the prevalence of complications in patients with EV71 infection were higher than those in patients in CA6, CA10 or CA16 infection (P < 0.05 for all comparisons). Children with CA12 infection were the youngest, and most likely have the highest risk of complications when compared to the other non-EV71 infection groups. Conclusions This study demonstrated a diversified pathogen compositions attributing to HFMD and clinical symptoms differing in enterovirus genotypes. It deserves our attention as early identification of enterovirus genotypes is important for diagnosis and treatment of HFMD patients. PMID:24148902

Numerical Calculation of the Peaking Factor of a Water-Cooled W/Cu Monoblock for a Divertor

2015-09-01

In order to accurately predict the incident critical heat flux (ICHF, the heat flux at the heated surface when CHF occurs) of a water-cooled W/Cu monoblock for a divertor, the exact knowledge of its peaking factors (fp) under one-sided heating conditions with different design parameters is a key issue. In this paper, the heat conduction in the solid domain of a water-cooled W/Cu monoblock is calculated numerically by assuming the local heat transfer coefficients (HTC) of the cooling wall to be functions of the local wall temperature, so as to obtain fp. The reliability of the calculation method is validated by an experimental example result, with the maximum error of 2.1% only. The effects of geometric and flow parameters on the fp of a water-cooled W/Cu monoblock are investigated. Within the scope of this study, it is shown that the fp increases with increasing dimensionless W/Cu monoblock width and armour thickness (the shortest distance between the heated surface and Cu layer), and the maximum increases are 43.8% and 22.4% respectively. The dimensionless W/Cu monoblock height and Cu thickness have little effect on fp. The increase of Reynolds number and Jakob number causes the increase of fp, and the maximum increases are 6.8% and 9.6% respectively. Based on the calculated results, an empirical correlation on peaking factor is obtained via regression. These results provide a valuable reference for the thermal-hydraulic design of water-cooled divertors. supported by National Magnetic Confinement Fusion Science Program of China (No. 2010GB104005) and Funding of Jiangsu Innovation Program for Graduate Education, China (CXLX12_0170), the Fundamental Research Funds for the Central Universities of China

Celiac disease is a chronic inflammatory enteropathy with a symptom spectrum similar to that of irritable bowel syndrome (IBS). It is a common but largely undiagnosed condition in the Western countries. However, it is extremely rare among Chinese individuals, and few studies have investigated its prevalence in China. The aim was to determine the prevalence of celiac disease in patients with IBS who were diagnosed using the Rome III criteria in a single center of northern China. This was a single-center, prospective, controlled cohort study performed in Qilu Hospital involving 246 patients with IBS and 246 healthy controls. Blood samples were drawn to assess serum tissue transglutaminase immunoglobulin A (tTg-IgA). Patients with a positive or equivocal tTg-IgA (≥15 U/mL) were subjected to probe-based confocal laser endomicroscopy (pCLE) and duodenal biopsy to confirm celiac disease. Altogether 12 (4.9%) patients with IBS and two (0.8%) healthy controls were positive or equivocal for serum tTg-IgA. Of these, five patients with IBS underwent pCLE and a targeted biopsy; all were histopathologically found to have celiac disease, although one was eventually diagnosed with lymphoma. After implementation of a gluten-free diet, seven patients serologically positive for IBS showed clinical improvement, thus our study illustrated a minimum prevalence of 2.85% of celiac disease among patients with IBS in our center. Celiac disease is not rare in Chinese individuals, particularly among those with IBS. Therefore, it should receive higher attention in clinical practice in China. © 2018 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Background: To investigate the incidence and risk factors of retinopathy of prematurity (ROP) in two Neonatal Intensive Care Units in North and South of China, respectively. Methods: We studied data concerning 472 infants with gestational age (GA) ≤34 weeks or birth weight (BW) ≤2000 g who were admitted to the Zhujiang Hospital of Southern Medical University and the Fourth Hospital of Shijiazhuang between January 1, 2011 and December 31, 2011. Clinical information about perinatal neonates was collected and was confirmed by reviewing medical charts. The incidence and severity of ROP were assessed in the screened population. Main outcome measures are the incidence and severity of ROP. The relationship of clinical risk factors and the development of ROP were analyzed. Results: The overall incidence of ROP was 12.7%, and the overall incidence of type 1 ROP was 2.3%; 9.4% of infants in Zhujiang Hospital had ROP compared to 15.0% infants in the Fourth Hospital of Shijiazhuang developed ROP, and the difference is statistically significant. ROP was significantly associated with GA (odds ratio [OR]: 0.77 [0.62–0.95], P = 0.015), BW (OR: 0.998 [0.996–0.999], P = 0.008), maternal supplemental oxygen administration before and during delivery (OR: 4.27 [1.21–15.10], P = 0.024) and preeclampsia (OR: 6.07 [1.73–21.36] P = 0.005). The risk factors for ROP are different in two hospitals. In Zhujiang Hospital, BW is the independent risk factors for ROP while GA, BW and preeclampsia in the Fourth Hospital in Shijiazhuang Conclusions: Retinopathy of prematurity incidence is different based on area. Incidence of ROP is still high in China. More efforts need to prevent ROP. PMID:25836612

Ecological models have emphasized that short sleep duration (SSD) is influenced by both individual and environmental variables. However, few studies have considered the latter. The present study explores the influence of urban and regional contextual factors, net of individual characteristics, on the prevalence of SSD among university students in China. Participants were 11,954 students, who were identified through a multistage survey sampling process conducted in 50 universities. Individual data were obtained through a self-administered questionnaire, and contextual variables were retrieved from a national database. Multilevel logistic regression models were used to examine urban and regional variations in high and moderate levels of SSD. Overall the prevalence of high SSD (<6 hours sleep duration) was 2.8% (95% CI: 1.7%,3.9%) and moderate SSD (<7 hours) 24.7% (95% CI: 19.5%, 29.8%). Multilevel logistic regressions confirmed that home region gross domestic product (GDP) and the university regional unemployment rate were associated with SSD, net of other individual- and city-level covariates. Students attending high-level universities also recorded the highest levels of SSD. Of the individual characteristcs, only mother's occupation and student mental health status were related to SSD. The results of this study add important insights about the role of contextual factors affecting SSD among young adults and indicate the need to take into account both past, as well as present, environmental influences to control SSD.

To enhance the utility of satellite-derived cloud properties for studying the role of clouds in climate change and the hydrological cycle in semi-arid areas, it is necessary to know their uncertainties. This paper estimates the uncertainties of several cloud properties by comparing those derived over the China Loess Plateau from the MODerate-resolution Imaging Spectroradiometer (MODIS) on Terra and Aqua by the Clouds and Earth's Radiant Energy System (CERES) with surface observations at the Semi-Arid Climate and Environment Observatory of Lanzhou University (SACOL). The comparisons use data from January 2008 to June 2010 limited to single layer and overcast stratus conditions during daytime. Cloud optical depths (τ) and liquid water paths (LWP) from both Terra and Aqua generally track the variation of the surface counterparts with modest correlation, while cloud effective radius (re) is only weakly correlated with the surface retrievals. The mean differences between Terra and the SACOL retrievals are -4.7±12.9, 2.1±3.2 μm and 30.2±85.3 g m-2 for τ, re and LWP, respectively. The corresponding differences for Aqua are 2.1±8.4, 1.2±2.9 μm and 47.4±79.6 g m-2, respectively. Possible causes for biases of satellite retrievals are discussed through statistical analysis and case studies. Generally, the CERES-MODIS cloud properties have a bit larger biases over the Loess Plateau than those in previous studies over other locations.

University Students' Views on Political Influences and the Status of Law in Post-Reform China: A Moderation and Mediation Analysis.

PubMed

Jiang, Guoping; Lo, T Wing

2016-07-01

Scholars categorize societies into "rule of man" societies, "rule by law" societies, and "rule of law" societies on the basis of a status of law. After 1978, China's leaders invoked law as an alternative to the arbitrariness of the Cultural Revolution. In this study, we used quantitative methods to explore university students' views on the status of law in post-reform China. Surveys were conducted in three national universities located in different regions of China. Responses from university students show that their perceptions of well-developed legislation and perceptions of the publicity of law are associated with their perceptions of equality before the law, which could be the consequence of a "rule of law" system. However, the study found that university students are of the view that the political nature of legislation and interference in law enforcement moderate the relationship between legislation and equality before the law. The political nature of legislation also moderates the mediation effect of interference in law enforcement between law publicity and equality before the law. As such, the article concludes that although university students are no longer primary movers in China's social and political development after the Tiananmen incident, they are still knowledgeable if not critical about the status of law and its political implications. © The Author(s) 2015.

We investigated a diarrhea outbreak in 2 universities to identify the etiological agent responsible, the source of infection, the mode of transmission, and the risk factors. A case-controlled study was conducted using case students and asymptomatic control students who were selected randomly and frequency-matched according to class and age, and the source of food or water intake was investigated. Of the total 22,404 students at the universities, 0.25% developed Salmonella Infections. A total of 96% (54/56) of the case students and 30% (35/117) of the control students consumed bread products provided by the same vendor (odds ratio [OR] = 63.3; 95% confidence interval [CI], 14.9-550.7). Among the students who consumed bread, 96% (52/54) of the case students and 9% (3/35) of the control students ate egg sandwiches (OR = 277.3; 95%CI, 43.9-1,750.8). Seven strains of Salmonella enteritidis and 6 strains of S. chester were isolated from the case students or food samples. Pulsed-field gel electrophoresis typing showed the same patterns. The outbreak of gastroenteritis was caused mainly by egg sandwiches contaminated with different serotypes of Salmonella.

The novel influenza A H7N9 virus emerged recently in mainland China, whereas the influenza A H5N1 virus has infected people in China since 2003. Both infections are thought to be mainly zoonotic. We aimed to compare the epidemiological characteristics of the complete series of laboratory-confirmed cases of both viruses in mainland China so far. An integrated database was constructed with information about demographic, epidemiological, and clinical variables of laboratory-confirmed cases of H7N9 (130 patients) and H5N1 (43 patients) that were reported to the Chinese Centre for Disease Control and Prevention until May 24, 2013. We described disease occurrence by age, sex, and geography, and estimated key epidemiological variables. We used survival analysis techniques to estimate the following distributions: infection to onset, onset to admission, onset to laboratory confirmation, admission to death, and admission to discharge. The median age of the 130 individuals with confirmed infection with H7N9 was 62 years and of the 43 with H5N1 was 26 years. In urban areas, 74% of cases of both viruses were in men, whereas in rural areas the proportions of the viruses in men were 62% for H7N9 and 33% for H5N1. 75% of patients infected with H7N9 and 71% of those with H5N1 reported recent exposure to poultry. The mean incubation period of H7N9 was 3·1 days and of H5N1 was 3·3 days. On average, 21 contacts were traced for each case of H7N9 in urban areas and 18 in rural areas, compared with 90 and 63 for H5N1. The fatality risk on admission to hospital was 36% (95% CI 26-45) for H7N9 and 70% (56-83%) for H5N1. The sex ratios in urban compared with rural cases are consistent with exposure to poultry driving the risk of infection--a higher risk in men was only recorded in urban areas but not in rural areas, and the increased risk for men was of a similar magnitude for H7N9 and H5N1. However, the difference in susceptibility to serious illness with the two different viruses remains unexplained, since most cases of H7N9 were in older adults whereas most cases of H5N1 were in younger people. A limitation of our study is that we compared laboratory-confirmed cases of H7N9 and H5N1 infection, and some infections might not have been ascertained.

2012-11-01

The 26th IAHR Symposium on Hydraulic Machinery and Systems, will be held in Beijing, China, 19-23 August 2012. It is jointly organized by Tsinghua University, State Key Laboratory of Hydro Science and Hydraulic Engineering, China, Jiangsu University, Xi'an University of Technology, China Agricultural University, National Engineering Research Center of Hydropower Equipment and Dongfang Electric Machinery Co., Ltd. It is the second time that China hosts such a symposium. By the end of 2011, the China electrical power system had a total of 1 050 GW installed power, out of which 220 GW was in hydropower plants. The energy produced in hydropower facilities was 662.6 TWh from a total of 4,720 TWh electrical energy production in 2011. Moreover, in 2020, new hydropower capacities are going to be developed, with a total of 180 GW installed power and an estimated 708 TWh/year energy production. And in 2011, the installed power of pumped storage stations was about 25GW. In 2020, the data will be 70GW. At the same time, the number of pumps used in China is increasing rapidly. China produces about 29,000,000 pumps with more than 220 series per year. By the end of 2011, the Chinese pumping system has a total of 950 GW installed power. The energy consumed in pumping facilities was 530 TWh in 2011. The pump energy consumption accounted for about 12% of the national electrical energy production. Therefore, there is a large market in the field of hydraulic machinery including water turbines, pump turbines and a variety of pumps in China. There are also many research projects in this field. For example, we have conducted National Key Research Projects on 1000 MW hydraulic turbine, and on the pump turbines with high head, as well as on the large capacity pumps for water supply. Tsinghua University of Beijing is proud to host the 26th IAHR Symposium on Hydraulic Machinery and Systems. Tsinghua University was established in 1911, after the founding of the People's Republic of China. It was molded into a polytechnic institute focusing on engineering in the nationwide restructuring of universities and colleges undertaken in 1952. At present, the university has 14 schools and 56 departments with faculties in science, engineering, humanities, law, medicine, history, philosophy, economics, management, education and art. The University now has over 25 900 students, including 13 100 undergraduates and 12 800 graduate students. As one of China's most renowned universities, Tsinghua has become an important institution for fostering talents and scientific research. The International Association of Hydro-Environment Engineering and Research (IAHR) particularly promotes the advancement and exchange of knowledge through working groups, specialty symposia, congresses, and publications on water resources, river and coastal hydraulics, risk analysis, energy, environment, disaster prevention, and industrial processes. The IAHR Committee on Hydraulic Machinery and Systems deals with the advancement of technology associated with the understanding of steady and unsteady flow characteristics in hydraulic machinery and conduit systems connected to the machinery. The technology elements include the fluid behaviour within machine components, hydro-elastic behaviour of machine components, cavitation and two phase flow in turbines and pumps, hydraulic machine and plant control systems, the use of hydraulic machines to improve water quality, and even considerations to improve fish survival in their passage through hydro plants. The main emphases of the IAHR Committee on Hydraulic Machinery and Systems are to stimulate research and understanding of the technologies associated with hydraulic machinery and to promote interaction between the machine designers, machine users, the academic community, and the community as a whole. Hydraulic machinery is both cost effective and environmentally friendly. The goals of the IAHR Committee on Hydraulic Machinery and Systems are to improve the value of hydraulic machinery to the end user, to the societies, and to improve societies understanding and appreciation of that value. The series of IAHR Symposia on Hydraulic Machinery and Cavitation started with the 1st edition in Nice, France, 1960. For the past decade, all the symposia have focused on an extended portfolio of topics under the name of 'Hydraulic Machinery and Systems', such as the 20th edition in Charlotte, USA, 2000, the 21st in Lausanne, Switzerland, 2002, the 22nd in Stockholm, Sweden, 2004, the 23rd in Yokohama, Japan, 2006, the 24th in Foz do Iguassu, Brasil, 2008, and the 25th in Timisoara, Romania, 2010. The 26th IAHR Symposium on Hydraulic Machinery and Systems brings together more than 250 scientists and researchers from 25 countries, affiliated with universities, technology centers and industrial firms to debate topics related to advanced technologies for hydraulic machinery and systems, which will enhance the sustainable development of water resources and hydropower production. The Scientific Committee has selected 268 papers, out of 430 abstracts submitted, on the following topics: (i) Hydraulic Turbines and Pumps, (ii) Sustainable Hydropower, (iii) Hydraulic Systems, (iv) Advances in Computational and Experimental Techniques, (v) Application in Industries and in Special Conditions, to be presented at the symposium and to be included in the proceedings. All the papers, published in this Volume 15 of IOP Conference Series: Earth and Environmental Science, have been peer reviewed through processes administered by the editors of the 26th IAHR Symposium on Hydraulic Machinery and Systems proceedings, those are Yulin Wu, Zhengwei Wang, Shuhong Liu, Shouqi Yuan, Xingqi Luo and Fujun Wang. We sincerely hope that this edition of the symposium will be a significant step forward in the worldwide efforts to address the present challenges facing the modern Hydraulic Machinery and Systems.

The levels of 12 synthetic musks and one musk metabolite in 24 pooled human milk samples were examined in order to assess the health risks of these contaminants to breast-feeding infants of China. The 24 pooled samples comprised of 1237 individual human milk samples collected from 12 provinces of China according to WHO guidelines. Among the 13 target analytes, OTNE ([1,2,3,4,5,6,7,8-octahydro-2,3,8,8-tetramethylnaphthalen-2yl]ethan-1-one), HHCB (1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethylcyclopenta[γ]-2-benzopyran), AHTN (7-acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene), musk ketone (4-tert-butyl-2,6-dimethyl-3,5-dinitroacetophenone, MK), Musk T (1,4-dioxacyclohepta decane-5,17-dione), HHCB-lactone (1,3,4,6,7,8-hexahydro-4,6,6,7,8,8-hexamethyl cyclopenta[γ]-2-benzopyran-1-one) and musk ambrette (1-(1,1-dimethylethyl)-2-methoxy-4-methyl-3,5-dinitrobenzene, MA), were found in the milk samples analysed with mean (median) concentrations of 3.96 (3.91), 18.03 (15.10), 10.30 (9.38), 4.68 (4.45), < 3.70 (< 3.70), 10.02 (9.20) and < 5.20 (< 5.20) ng g(-1) lipid weight, respectively, whereas ADBI (4-acetyl-1,1-dimethyl-6-tert-butylindan), AHDI (6-acetyl-1,1,2,3,3,5-hexamethylindan), ATII (5-acetyl-1,1,2,6-tetramethyl-3-isopropylindan), musk xylene (1-tert-butyl-3,5-dimethyl-2,4,6-trinitrobenzene, MX), musk tibetene (1-tert-butyl-3,4,5-trimethyl-2,6-dinitrobenzene, MT) and musk moskene (1,1,3,3,5-pentamethyl-4,6-dinotroindane, MM) were not detected. Significantly positive associations were observed in concentration levels between HHCB and AHTN (p < 0.001), HHCB and HHCB-lactone (p < 0.05), AHTN and HHCB-lactone (p < 0.001), and MK and OTNE (p < 0.05). No statistical difference was found in musk concentrations between rural and urban areas in China (p > 0.05). The mean (median) estimated daily intakes by infants were 20.5 (20.2), 93.4 (78.2), 53.4 (48.6), 24.2 (23.0) and 51.9 (47.6) ng kg(-1) body weight for OTNE, HHCB, AHTN, MK and HHCB-lactone, respectively. The musk exposure levels of infants in China via breast feeding were very low according to the current toxicological information.

China has gaps in the quality of care provided to patients with ST-elevation myocardial infarction, but little is known about how quality varies between hospitals. Using nationally representative data from the China PEACE-Retrospective AMI Study, we characterized the quality of care for ST-elevation myocardial infarction at the hospital level and examined variation between hospitals. Two summary measures were used to describe the overall quality of care at each hospital and to characterize variations in quality between hospitals in 2001, 2006, and 2011. The composite rate measured the proportion of opportunities a hospital had to deliver 6 guideline-recommended treatments for ST-elevation myocardial infarction that were successfully met, while the defect-free rate measured the proportion of patients at each hospital receiving all guideline-recommended treatments for which they were eligible. Risk-standardized mortality rates were calculated. Our analysis included 12 108 patients treated for ST-elevation myocardial infarction at 162 hospitals. The median composite rate increased from 56.8% (interquartile range [IQR], 45.9-72.0) in 2001 to 80.5% (IQR, 74.7-84.8) in 2011; however, substantial variation remained in 2011 with defect-free rates ranging from 0.0% to 76.9%. The median risk-standardized mortality rate increased from 9.9% (IQR, 9.1-11.7) in 2001 to 12.6% (IQR, 10.9-14.6) in 2006 before falling to 10.4% (IQR, 9.1-12.4) in 2011. Higher rates of guideline-recommended care and a decline in variation between hospitals are indicative of an improvement in quality. Although some variation persisted in 2011, very top-performing hospitals missed few opportunities to provide guideline-recommended care. Quality improvement initiatives should focus on eliminating residual variation as well as measuring and improving outcomes. URL: https://www.clinicaltrials.gov.

We assessed the magnitude, spatial patterns, and trends of WUE of China's terrestrial ecosystems and its responses to drought using a process-based ecosystem model. During the period from 2000 to 2011, the national average annual WUE (net primary productivity (NPP)/evapotranspiration (ET)) of China was 0.79 g C kg-1 H2O. Annual WUE decreased in the southern regions because of the decrease in NPP and increase in ET and increased in most northern regions mainly because of the increase in NPP. Droughts usually increased annual WUE in Northeast China and central Inner Mongolia but decreased annual WUE in central China. "Turning-points" were observed for southern China where moderate and extreme drought reduced annual WUE and severe drought slightly increased annual WUE. The cumulative lagged effect of drought on monthly WUE varied by region. Our findings have implications for ecosystem management and climate policy making. WUE is expected to continue to change under future climate change particularly as drought is projected to increase in both frequency and severity.

Objective: To investigate the development status and risk factors of infants and toddlers in rural China. Methods: In this cohort study, 603 infants (6-12 months of age, Phase Ⅰ) in the rural areas of QinLing-Bashan (Qin-Ba) in Shaanxi were recruited in the control group that received no intervention from April 2013 to October 2015. Three follow-up visits were performed every six months (Phase Ⅱ(12-18 months of age), Phase Ⅲ (18-24 months of age) and Phase Ⅳ(24-30 months of age)). In all the 4 phases (Ⅰ-Ⅳ), general data of the children and the families were collected by questionnaires, early childhood growth and development were assessed by door to door visits, children's hemoglobin levels were determined by laboratory tests, and the cognitive and motor development screening was conducted by the Bayley Scales of Infant and Toddler Development. Logistic regression was used to analyze the risk factors affecting the development of infants and toddlers in rural areas and the data were analyzed in terms of risk factors from infants, guardians and family. Results: Phase Ⅱ, Phase Ⅲ and Phase Ⅳ survey recruited 497, 483 and 486 participants respectively. The incidences of cognitive impairment (mental development scores<80) in rural areas of southern Shaanxi were 13.4% (81/603) in Phase Ⅰ(6-12 months), 20.1%(100/497) in PhaseⅡ(12-18 months), 42.9% (207/483) in Phase Ⅲ(18-24 months) and 50.4%(245/486) in Phase Ⅳ(24-30 months) respectively, which showed a significant increase with age (χ(2)=233.40, P< 0.01); the incidences of psychomotor impairment (psychomotor development scores<80) of Phase Ⅰ, Phase Ⅱ, Phase Ⅲ and Phase Ⅳ were 25.0% (151/603), 26.8% (133/497), 8.3% (40/483) and 11.9% (58/486), which showed a significant decrease with age (χ(2)=87.08, P< 0.01). Multivariate logistic regression analysis showed that the leading risk factor of the cognitive development of 24-30-month-old children was the mothers' poor education background (≤9 years of school education) ( OR= 2.56, P< 0.01), and the main risk factors affecting psychomotor development were the mothers' poor education background (≤9 years of school education) ( OR= 2.64, P< 0.05) and growth retardation ( OR= 2.95, P= 0.07). Conclusions: The early childhood development (especially cognitive development) in the rural areas of Qin-Ba in Shaanxi of China is not optimistic. More attention should be paid to the early childhood development in rural China, especially to the development of children from the mothers with poor education background.

Taste and odor (T/O) in drinking water often cause consumer complaints and are thus regulated in many countries. However, people in different regions may exhibit different sensitivities toward T/O. This study proposed a method to determine the regional drinking water odorant regulation goals (ORGs) based on the odor sensitivity distribution of the local population. The distribution of odor sensitivity to 2-methylisoborneol (2-MIB) by the local population in Beijing, China was revealed by using a normal distribution function/model to describe the odor complaint response to a 2-MIB episode in 2005, and a 2-MIB concentration of 12.9 ng/L and FPA (flavor profile analysis) intensity of 2.5 was found to be the critical point to cause odor complaints. Thus the Beijing ORG for 2-MIB was determined to be 12.9 ng/L. Based on the assumption that the local FPA panel can represent the local population in terms of sensitivity to odor, and that the critical FPA intensity causing odor complaints was 2.5, this study tried to determine the ORGs for seven other cities of China by performing FPA tests using an FPA panel from the corresponding city. ORG values between 12.9 and 31.6 ng/L were determined, showing that a unified ORG may not be suitable for drinking water odor regulations. This study presents a novel approach for setting drinking water odor regulations. Copyright © 2014. Published by Elsevier B.V.

The 12th International Symposium on Multiscale, Multifunctional and Functionally Graded Materials (FGM-2012) was held in Beijing, China, from 22-36 October 2012. This was part of a series of conferences organized every two years endorsed by International Advisory Committee for FGM's, which serves as a forum for scientists, educators, engineers and young students interested in the development of functionally graded materials (FGM). The series continues from the previous international symposium on FGM held in Sendai, Japan (1990), San Francisco, USA (1992), Lausanne, Switzerland (1994), Tsukuba, Japan (1996), Dresden, Germany (1998), Estes Park, USA (2000), Beijing, China (2002), Leuven, Belgium (2004), Hawaii, USA (2006), Sendai, Japan (2008) and Guimaraes, Portugal (2010). Functionally graded materials are non-uniform materials which are designed with embodied continuous spatial variations in composition and microstructure for the specific purpose of adjusting their thermal, structural, mechanical, biological or functional response to specific application conditions. Such multi-phase materials cover a range of space and time scales, and are best understood by means of a comprehensive multiscale, multiphysics approach. These kinds of materials are presently in the forefront of materials research, receiving worldwide attention. They have a broad range of applications including for example, biomedical, biomechanical, automotive, aerospace, mechanical, civil, nuclear, and naval engineering. New applications are continuously being discovered and developed. The objective of the FGM-2012 intends to provide opportunities for exchanging ideas and discussing state-of-the-art theories, techniques and applications in the fields of multiscale, multifunctional and FGM, through invited lectures, oral and poster presentations. FGM-2012 was organized and hosted by University of Science and Technology Beijing, China, together with Tsing-hua University and Wuhan University of Technology, and was supported by National Natural Science Foundation of China. On behalf of the organizing committee of FGM-2012, I express my great appreciation to their support of the symposium. Nearly 100 scholars and students from Japan, Brazil, Germany, Russia, United States of America, Portugal, France, Switzerland, Turkey, Singapore, China, and so on, attended FGM-2012, and 57 of the presented papers were collected and selected for publication. The subjects of these papers cover simulation and characterization, advanced fabrication technology, novel application of FGM and layer materials. I cordially thank all of the authors and attendees for their support, and my appreciation is also given to the advisory committee, organizing committee, and the conference volunteers for their hard work.

Predominant modes of hepatitis C virus (HCV) transmission vary between countries and over time. To compare HCV transmission modes in the USA and northern China. We conducted a prospective study enrolling two cohorts of chronic HCV patients in the USA, and in China at Beijing, and at Gu'an and Kuancheng counties in Hebei. Patients self-reported the most likely source and year of infection. A total of 1957 patients were studied (1000 USA; 957 China-428 Beijing, 387 Gu'an, 142 Kuancheng). The predominant infection sources were transfusion (23.0%) and injection drug use (IDU) (32.1%) in the USA and transfusion (64.5%) in northern China. Within China, transfusion was the most common source in Beijing (62.1%) and Gu'an (88.1%), and medical procedures (35.9%) and IDU (12.0%) in Kuancheng. Infection via transfusion decreased significantly in the USA (35.1-4.6%) and Beijing (84.2-14.3%) but remained frequent in Gu'an (90.5-72.5%) over time. Infection via IDU decreased from 32.4% in those ≥61 years to 25.0% in those 41-50 years but increased to 46.5% in those ≤40 years in US patients and decreased over time from 38.7 to 1.9% in Kuancheng. Infection via medical procedures increased over time in Beijing (7.0-33.3%) and remained frequent in Kuancheng (45.2-31.1%). There are major differences in presumed HCV infection source between the USA and northern China. Favorable as well as worrisome changes in the modes of HCV transmission in both countries were observed.

The dominant mode of HIV transmission in China has changed from injection drug use to sexual contact. The objectives of this study were to describe the disassortative and assortative mixing patterns of drug-using and sex networks among young drug users in China. Cross-sectional study. Respondent-driven sampling (RDS) was used to recruit young drug users in an egocentric network study in Yunnan, China. Egos were categorized as having disassortative mixing network patterns if they reported both sex and drug-using networks. Egos who only had a sex network (no drug-using network), or only a drug-using network (no sex network) were categorized as having assortative mixing network patterns. Multiple logistic regression was performed to analyze the relationships between disassortative patterns with risky sexual behaviour and drug-using practices. A total of 426 participants were recruited into the study. Two hundred forty-two egos reported disassortative mixing patterns and 139 egos had assortative patterns. The RDS-adjusted proportion of having a disassortative pattern was 53.2%. Participants with disassortative patterns were more likely to engage in HIV risk behaviour compared to those with assortative patterns. Specifically, drug users with disassortative patterns reported more multiple sex partners (31.4% vs 19.6%), concurrent partnerships (52.1% vs 39.0%), non-regular sex partners (12.0% vs 4.3%), and sex partners who were IDUs (24.9% vs 12.5%). Consistent condom use with regular or non-regular partners was low (between 18.9% and 47.2%) regardless of the mixing pattern. However, parenteral risk for HIV transmission was relatively low in both groups. The transition of the HIV epidemic in China from injection drug use to sexual contact may be attributed to disassortative mixing in drug-use and sexual networks. HIV programs should consider disassortative mixing patterns when designing new behavioural interventions. Copyright © 2015 The Royal Society for Public Health. Published by Elsevier Ltd.

Toxoplasmosis, caused by the obligate intracellular protozoan parasite Toxoplasma gondii, has become a serious public health problem worldwide. T. gondii can infect almost all warm-blooded animals, including parrots. However, little is known of T. gondii infection in parrots in China. Antibodies against T. gondii in 311 parrots including 202 Budgerigars (Melopsittacus undulatus), 26 Lovebirds (Agapornis sp.), 22 Cockatiels (Nymphicus hollandicus), and 61 Alexandrine Parakeets (Psittacula eupatria) in the cities of Beijing and Weifang in north China were tested using the modified agglutination test (MAT). Twenty-six (8.36%) out of 311 serum samples were positive for T. gondii at the cutoff of 1:5. Among the four species, a higher seroprevalence of T. gondii was found in Cockatiels (13.64%, 95% confidence interval [CI] 0.00-27.98), although the difference was not statistically significant (p=0.61). Seropositivity rates against T. gondii in male parrots (10.43%, 95% CI 5.74-15.12) were not statistically different from that in female parrots (6.08%, 95% CI 2.23-9.93, p=0.17). The seropositivity of T. gondii in parrots from Weifang and Beijing was 11.11% (95% CI 6.13-16.09) and 5.70% (95% CI 2.08-9.31), respectively. The seroprevalence varied in parrots of different age groups, ranging from 5.71% (95% CI 1.27-10.15) to 13.00% (95% CI 6.41-19.69), however, the difference among age groups was not statistically significant (p=0.12). The seroprevalence of T. gondii infection in parrots in summer (11.63%, 95% CI 6.84-16.42) was significantly higher than in spring (4.32%, 95% CI 0.94-7.70, p=0.02). The results of the present survey indicated that parrots in China are exposed to T. gondii. To our knowledge, this is the first report of T. gondii seroprevalence in parrots in China.

CH4 mole fractions were continuously measured from 2009 to 2011 at three WMO/GAW stations in China (Lin'an, LAN; Longfengshan, LFS; and Waliguan, WLG) using three Cavity Ring Down Spectroscopy instruments. LAN and LFS are GAW regional measurement stations. LAN is located in China's most economically developed region, and LFS is in a rice production area (planting area > 40,000 km2). WLG is a global measurement station in remote northwest China. At LAN, high methane mole fractions are observed in all seasons. Surface winds from the northeast enhance CH4 values, with a maximum increase of 32 ± 15 ppb in summer. The peak to peak amplitude of the seasonal cycle is 77 ± 35 ppb. At LFS, the diurnal cycle amplitude is approximately constant throughout the year except summer, when a value of 196 ± 65 ppb is observed. CH4 values at LFS reach their peak in July, which is different from seasonal variations typically observed in the northern hemisphere. CH4 mole fractions at WLG show both the smallest values and the lowest variability. Maximum values occur during summer, which is different from other northern hemisphere WMO/GAW global stations. The seasonal cycle amplitude is 17 ± 11 ppb. The linear growth rates at LAN, LFS, and WLG are 8.0 ± 1.2, 7.9 ± 0.9, and 9.4 ± 0.2 ppb yr-1, respectively, which are all larger than the global mean over the same 3 year period. Results from this study attempt to improve our basic understanding of observed atmospheric CH4 in China.

Although stroke in the young and middle aged accounts for 31% of all strokes in China, the disease burden is unknown. We aimed to determine the secular trends in stroke incidence and the transition of subtypes in rural China over a 24-year period. In 1992, 14 920 residents were recruited to participate in the Tianjin Brain Study. Stroke events and all deaths were registered annually. We assessed the trends in incidence of first-ever stroke, including intracerebral hemorrhage and ischemic stroke, among adults aged 35 to 64 years during 1992 to 1999, 2000 to 2007, and 2008 to 2015. The annual proportion of change in stroke incidence was evaluated from 1992 to 2015. The age-standardized incidence of first-ever stroke per 100 000 person-years increased significantly, from 122 in 1992 to 1999, to 215.8 in 2000 to 2007, to 471.8 in 2008 to 2015. The incidence of first-ever stroke increased annually by 11.9% overall (12.4% in men, 9.0% in women, 8.7% for intracerebral hemorrhage, and 10.7% for ischemic stroke; P<0.001). The greatest increases were observed in adults aged 55 to 64 years, with an annual increase of 11.6% for ischemic stroke (10.8% in men and 6.9% in women). However, the proportion of intracerebral hemorrhage has not changed over the past 24 years. In contrast with that in developed countries, the burden of stroke in China originates primarily from young and middle-aged adults. Thus, control of risk factors in this population is required to reduce the future burden of stroke in China. © 2016 American Heart Association, Inc.

Abstract: Anthropogenic atmospheric emissions of air pollutants have caused worldwide concerns due to their adverse effects on human health and the ecosystem. By determining the best available emission factors for varied source categories, we established the comprehensive atmospheric emission inventories of hazardous air pollutants including 12 typical toxic heavy metals (Hg, As, Se, Pb, Cd, Cr, Ni, Sb, Mn, Co, Cu, and Zn) from primary anthropogenic activities in Beijing-Tianjin-Hebei (BTH) region of China for the period of 2012 for the first time. The annual emissions of these pollutants were allocated at a high spatial resolution of 9km × 9km grid with ArcGIS methodology and surrogate indexes, such as regional population and gross domestic product (GDP). Notably, the total heavy metal emissions from this region represented about 10.9% of the Chinese national total emissions. The areas with high emissions of heavy metals were mainly concentrated in Tangshan, Shijiazhuang, Handan and Tianjin. Further, WRF-CMAQ modeling system were applied to simulate the regional concentration of heavy metals to explore their spatial-temporal variations, and the source apportionment of these heavy metals in BTH region was performed using the Brute-Force method. Finally, integrated countermeasures were proposed to minimize the final air pollutants discharge on account of the current and future demand of energy-saving and pollution reduction in China. Keywords: heavy metals; particulate matter; emission inventory; CMAQ model; source apportionment Acknowledgment.

Simulation and projection of the characteristics of heat waves over China were investigated using 12 CMIP5 global climate models and the CN05.1 observational gridded dataset. Four heat wave indices (heat wave frequency, longest heat wave duration, heat wave days, and high temperature days) were adopted in the analysis. Evaluations of the 12 CMIP5 models and their ensemble indicated that the multi-model ensemble could capture the spatiotemporal characteristics of heat wave variation over China. The inter-decadal variations of heat waves during 1961-2005 can be well simulated by multi-model ensemble. Based on model projections, the features of heat waves over China for eight different global warming targets (1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0 °C) were explored. The results showed that the frequency and intensity of heat waves would increase more dramatically as the global mean temperature rise attained higher warming targets. Under the RCP8.5 scenario, the four China-averaged heat wave indices would increase from about 1.0 times/year, 2.5, 5.4, and 13.8 days/year to about 3.2 times/year, 14.0, 32.0, and 31.9 days/year for 1.5 and 5.0 °C warming targets, respectively. Those regions that suffer severe heat waves in the base climate would experience the heat waves with greater frequency and severity following global temperature rise. It is also noteworthy that the areas in which a greater number of severe heat waves occur displayed considerable expansion. Moreover, the model uncertainties exhibit a gradual enhancement with projected time extending from 2006 to 2099.

Data on the epidemiology of invasive candidiasis (IC) and antifungal susceptibility of Candida isolates in China are still limited. Here we report surveillance for IC from the China Hospital Invasive Fungal Surveillance Net (CHIF-NET) Study. Sixty-five tertiary hospitals collected 8,829 Candida isolates from August 1, 2009 to July 31, 2014. Matrix-assisted laser desorption/ionization -time of flight mass spectrometry supplemented by rDNA sequencing was used to define species, and fluconazole and voriconazole susceptibilities determined by the Clinical and Laboratory Standards Institute disk diffusion method. A total of 32 Candida species were identified. C. albicans was the most common species (44.9%) followed by C. parapsilosis complex (20.0%), C. tropicalis (17.2%) and C. glabrata complex (10.8%), with other species comprising <3%. However, in candidemia, the proportion of cases caused by C. albicans was only 32.3%. C. albicans and C. parapsilosis complex isolates were susceptible to fluconazole and voriconazole (<6% resistance), while fluconazole- and azole cross-resistant rates were high in C. tropicalis (13.3% and 12.9%), C. glabrata complex (18.7% and 14%) and uncommon Candida species (44.1% and 10.3%) isolates. Moreover, from year 1 to 5 of the study, there was a significant increase in resistant rates amongst C. glabrata complex isolates to fluconazole (12.2% to 24.0%), and amongst C. tropicalis isolates to both fluconazole (5.7% to 21.0%) and voriconazole (5.7% to 21.4%) (all P<0.01). Geographic variations in causative species and susceptibilities were noted. Our findings indicated that antifungal resistance have become noteworthy in China, and enhanced surveillance is warranted.

We analyzed trends in rates of health insurance coverage in China in the period 1991-2011 and the association of health insurance with hypertension and diabetes based on data from eight waves of the China Health and Nutrition Survey. The rate of coverage fell from 32.3 percent in 1991 to 21.9 percent in 2000, rebounding to 49.7 percent in 2006 and then rapidly climbing to 94.7 percent in 2011. Our study indicated that neither the prevalence of diabetes nor that of hypertension was significantly associated with health insurance coverage. When patients were aware of their condition or disease, those with insurance had a significantly higher likelihood of treatment for diabetes and hypertension, compared to those without insurance. We observed an association between health insurance coverage and seeking preventive care and receiving medical treatment when patients were aware of their condition or disease.

Inequalities in demographic, socio-economic and health status for China labor force place them at greater health risks, and marginalized them in the utilization of healthcare services. This paper identifies the inequalities which limit the utilization of health services among China labor force, and provides a reference point for health policy. Data were collected from 23,505 participants aged 15 to 65, from the 2014 China Labor Force Dynamic Survey (a nationwide cross-sectional survey covering 29 provinces with a multi-stage cluster, and stratified, probability sampling strategy) conducted by Sun Yat-sen University. Logistic regression models were used to study the effects of demographic (age, gender, marital status, type of hukou and migration status), socio-economic (education, social class and insurance) and health status (self-perceived general health and several chronic illnesses) variables on the utilization of health services (two-week visiting and hospitalization during the past 12 months). Goodness of fit was assessed using Hosmer-Lemeshow test. Discrimination ability was assessed based on the area under the receiver operating curve (AUC). Migrants with more than 1 (OR 2.80, 95% CI 1.01 ~ 7.82) or none chronic illnesses (OR 1.26, 95% CI 1.01 ~ 7.82) are more likely to be two week visiting to the clinic than non-migrants; migrants with none chronic illnesses (OR 0.61, 95% CI 0.45 ~ 0.82) are less likely to be in hospitalization during the past 12 months than non-migrants. Female, elder, hukou of non-agriculture, higher education level, higher social class, purchasing more insurance and poorer self-perceived health were predictors for more utilization of health service. More insurance benefited more two-week visiting (OR 1.12, 95% CI 1.06 ~ 1.17) and hospitalization during the past 12 months (OR 1.12, 95% CI 1.07 ~ 1.18) for individuals with none chronic illness but not ≥1 chronic illnesses. All models achieved good calibration (Hosmer-Lemeshow test's P range of 0.258-0.987) and discrimination (AUC range of 0.626-0.725). This study has shown that there are inequalities of demographic, socio-economic and health status in the utilization of health services for China labor force. Prudent health policy with equitable utilization of health services eliminating mentioned inequalities should be a priority in shaping China's healthcare system reform.

2015-04-01

The new ecological paradigm is an ecocentric view of the relationship between humanity and nature. This study analyzed the correlates of the new ecological paradigm in China using the responses of 1,148 university students to a questionnaire. The participating students were from Lanzhou University and Liaocheng University in China and ranged in age from 16 to 26 years. This study showed that two materialist value orientations, economic precedence over the environment and trust in technology, were negatively correlated with the new ecological paradigm. The correlates of basic values with the new ecological paradigm were mediated by economic precedence over the environment. Female students were more concerned about the environment than were male students.

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.

2004-06-01

This study quantifies and compares patient characteristics in outpatient acupuncture. Prospective primary source evidence was gathered at two prominent outpatient acupuncture clinics in Beijing, China (n = 563, n = 233). The most common condition was Bell's palsy, which represented 20.6% and 25.3% of total cases at the two clinics, respectively. The second most common condition was cerebrovascular accident (CVA) rehabilitation. These treatments represented 11.9% and 12.0% of treatments at the two clinics, respectively. Other trends at the clinics included the following: (1) neurologic complaints predominated; (2) doctors see a large number of patients per day; (3) the majority of patients overall were female; while (4) the majority of patients treated for CVAs rehabilitation were male. As cultural and socioeconomic differences in perceptions of acupuncture exist between peoples of different countries, this study also compared patient main complaints in China to available data on acupuncture patients seen in other parts of China, Germany, the United Kingdom, Australia, and the United States. Except for the German clinic data, Western clinic acupuncturists saw more musculoskeletal complaints compared to China, where neurologic complaints predominated. Another significant difference between Asian and Western clinics was the number of patients seen per hour. While acupuncturists were reported to see 1.2 patients per hour in U. S. clinics, acupuncturists at the two Beijing, China, clinics saw 7.0 and 10.4 patients per hour, respectively. The main complaints seen in acupuncture outpatient clinics throughout the world likely result from a combination of inherent disease prevalence as well as patients' attitudes toward what acupuncture can treat successfully.

Hypertension is a significant risk factor for cardiovascular disease, and epidemiological evidence suggests that it is increasing in parallel with obesity in children and adolescents in low- and middle-income countries. To identify and determine the relationship between overweight, obesity and hypertension in a community sample of school children. Anthropometric data were collected from 12,730 school children aged 12-18 years in China, India and Mexico as part of the Community Interventions for Health programme, an international study evaluating community interventions to reduce non-communicable disease by addressing the three main risk factors of tobacco use, unhealthy diets and physical inactivity. Logistic regression was used to examine the association of body mass index and gender and hypertension. Prevalence rates of hypertension were 5.2% in China, 10.1% in India and 14.1% in Mexico, and pre-hypertension rates in China, India and Mexico were 13.4%, 9.4% and 11.2%, respectively. Overweight and obesity prevalence rates varied by country and were 16.6% in China, 4.1% in India and 37.1% in Mexico. In all countries there was a significant association between overweight and obesity and rates of hypertension. Overweight children were 1.7-2.3 times more likely to be hypertensive and obese children 3.5-5.5 more likely to show hypertension than those of normal weight. Rates of hypertension and overweight and obesity are high in school children in China, India and Mexico, and increased bodyweight is a significant risk factor for hypertension.

Abstract Objective To evaluate changes in the age-adjusted prevalence of disability in transitional China from 1987 to 2006. Methods Data from nationally representative surveys conducted in 1987 and 2006 were used to calculate age-adjusted disability prevalence rates by applying appropriate sample weights and directly adjusting to the age distribution of the 1990 Chinese population. Trends were assessed in terms of average annual percentage change. Findings The estimated number of disabled people in China in 1987 and 2006 was 52.7 and 84.6 million, respectively, corresponding to a weighted prevalence of 4.9% and 6.5%. The age-adjusted prevalence of disability decreased by an average of 0.5% per year (average annual percentage change, AAPC: −0.5%; 95% confidence interval, CI: −0.7 to −0.4) during 1987–2006. However, it increased by an average of 0.3% (AAPC: 0.3%; 95% CI: 0.1 to 0.5) per year in males and by an average of 1.0% (AAPC: 1.0%; 95% CI: 0.8 to 1.2) per year among rural residents, whereas among females it showed an average annual decrease of 1.5% (AAPC: −1.5%; 95% CI: −1.7 to −1.3) and among urban residents, an average annual decrease of 3.9% (AAPC: −3.9%; 95% CI: −4.3 to −3.5). Despite significant declining trends for hearing and speech, intellectual and visual disabilities, the annual age-adjusted prevalence of physical and mental disabilities increased by an average of 11.2% (AAPC: 11.2%; 95% CI: 10.5 to 11.9) and 13.3% (AAPC: 13.3%; 95% CI: 10.7 to 16.2), respectively. Conclusion In China, the age-adjusted prevalence of disability has declined since 1987, with inconsistencies dependent on the type of disability. These findings call for continuing and specific efforts to prevent disabilities in China. PMID:22084524

We conducted a national survey among medical students in China to estimate the prevalence of depressive symptoms and explore associated risk factors based on an established questionnaire composed of demographic information, life events in the past four weeks before survey, and the validated Chinese version of the 21-item Beck's Depression Inventory (BDI). The mean age of enrolled 9010 students was 20.7 (standard deviation: 1.6) years. BDI scores indicated that 19.9% had depressive symptoms based on the cut-off score of 14. Socioeconomic factors and student characteristics such as male sex, low monthly income per capita, father's poor education background, and higher year of study were associated with higher prevalence of depressive symptoms among medical students. Students who studied in comprehensive universities were more likely to have depressive symptoms compared with those from medical universities. Habitual smoking and alcohol drinking, sleep deprivation, and hospitalization or medication for one week or more in the last four weeks also predisposed students to higher risk of depressive symptoms. Our results indicate that depressive symptoms are becoming a highly prevalent health problem among Chinese medical students. Primary and secondary prevention should be prioritized to tackle this issue based on potential risk factors.

Neospora caninum is a worldwide protozoan that can induce neuromuscular disease in dogs and reproductive failure in domestic and wild ruminants. The objective of the present investigation was to determine the seroprevalence of N. caninum infection in farmed sika deer in China as little is known of this host-parasite relationship. A total of 1800 serum samples were collected during 2013 and 2014 from farmed sika deer in the major production areas of Liaoning, Jilin and Heilongjiang provinces.Assay by ELISA for N. caninum antibodies indicated a seroprevalence of 13.6% in 2013 and 15.8% in 2014, varying in different regions from 9.5% to 27.5%. Statistical analysis revealed that prevalence in animals aged >4 years (20.4%) was significantly higher than in the age ranges <2 years (9.6%) and 2-4 years (11.4%) (P<0.01). Moreover, sika deer in herds with a history of miscarriage (41.9%) had a significantly higher seroprevalence than in those without (12.6%) (P<0.01). The present survey confirms that N. caninum does occur in farmed sika deer in China and provides base-line data for the design and evaluation of measures for its control and prevention in this host.

China's rising hydropower demand challenges water sector.

Liu, Junguo; Zhao, Dandan; Gerbens-Leenes, P W; Guan, Dabo

2015-07-09

Demand for hydropower is increasing, yet the water footprints (WFs) of reservoirs and hydropower, and their contributions to water scarcity, are poorly understood. Here, we calculate reservoir WFs (freshwater that evaporates from reservoirs) and hydropower WFs (the WF of hydroelectricity) in China based on data from 875 representative reservoirs (209 with power plants). In 2010, the reservoir WF totaled 27.9 × 10(9) m(3) (Gm(3)), or 22% of China's total water consumption. Ignoring the reservoir WF seriously underestimates human water appropriation. The reservoir WF associated with industrial, domestic and agricultural WFs caused water scarcity in 6 of the 10 major Chinese river basins from 2 to 12 months annually. The hydropower WF was 6.6 Gm(3) yr(-1) or 3.6 m(3) of water to produce a GJ (10(9) J) of electricity. Hydropower is a water intensive energy carrier. As a response to global climate change, the Chinese government has promoted a further increase in hydropower energy by 70% by 2020 compared to 2012. This energy policy imposes pressure on available freshwater resources and increases water scarcity. The water-energy nexus requires strategic and coordinated implementations of hydropower development among geographical regions, as well as trade-off analysis between rising energy demand and water use sustainability.

Background Hand, foot and mouth disease (HFMD) is a common illness in China that mainly affects infants and children. The objective of this study is to assess the economic cost and health-related quality of life associated with HFMD in China. Method A telephone survey of caregivers were conducted in 31 provinces across China. Caregivers of laboratory-confirmed HFMD patients who were registered in the national HFMD enhanced surveillance database during 2012–2013 were invited to participate in the survey. Total costs included direct medical costs (outpatient care, inpatient care and self-medication), direct non-medical costs (transportation, nutrition, accommodation and nursery), and indirect costs for lost income associated with caregiving. Health utility weights elicited using EuroQol EQ-5D-3L and EQ-Visual Analogue Scale (VAS) were used to calculate associated loss in quality adjusted life years (QALYs). Results The subjects comprised 1136 mild outpatients, 1124 mild inpatients, 1170 severe cases and 61 fatal cases. The mean total costs for mild outpatients, mild inpatients, severe cases and fatal cases were $201 (95%CI $187, $215), $1072 (95%CI $999, $1144), $3051 (95%CI $2905, $3197) and $2819 (95%CI $2068, $3571) respectively. The mean QALY losses per HFMD episode for mild outpatients, mild inpatients and severe cases were 3.6 (95%CI 3.4, 3,9), 6.9 (95%CI 6.4, 7.4) and 13.7 (95%CI 12.9, 14.5) per 1000 persons. Cases who were diagnosed with EV-A71 infection and had longer duration of illness were associated with higher total cost and QALY loss. Conclusion HFMD poses a high economic and health burden in China. Our results provide economic and health utility data for cost-effectiveness analysis for HFMD vaccination in China. PMID:28934232

The lower reaches of the Yangtze River is one of the most developed regions in China. It is desirable to build compressed air energy storage (CAES) power plants in this area to ensure the safety, stability, and economic operation of the power network. Geotechnical feasibility analysis was carried out for CAES in impure bedded salt formations in Huai'an City, China, located in this region. First, geological investigation revealed that the salt groups in the Zhangxing Block meet the basic geological conditions for CAES storage, even though the possible unfavorable characteristics of the salt formations include bedding and different percentages of impurities. Second, mechanical tests were carried out to determine the mechanical characteristics of the bedded salt formations. It is encouraging that the samples did not fail even when they had undergone large creep deformation. Finally, numerical simulation was performed to evaluate the stability and volume shrinkage of the CAES under the following conditions: the shape of a single cavern is that of a pear; the width of the pillar is adopted as two times the largest diameter; three regular operating patterns were adopted for two operating caverns (internal pressure 9-10.5 MPa, 10-11.5 MPa, and 11-12.5 MPa), while the other two were kept at high pressure (internal pressure 10.5, 11.5, and 12.5 MPa) as backups; an emergency operating pattern in which two operating caverns were kept at atmospheric pressure (0.1 MPa) for emergency while the backups were under operation (9-10.5 MPa), simulated for 12 months at the beginning of the 5th year. The results of the analysis for the plastic zone, displacement, and volume shrinkage support the feasibility of the construction of an underground CAES power station.

Offering free glasses can be important to increase children's wear. We sought to assess whether "Upgrade glasses" could avoid reduced glasses sales when offering free glasses to children in China. In this cluster-randomized, controlled trial, children with uncorrected visual acuity (VA)< = 6/12 in either eye correctable to >6/12 in both eyes at 138 randomly-selected primary schools in 9 counties in Guangdong and Yunnan provinces, China, were randomized by school to one of four groups: glasses prescription only (Control); Free Glasses; Free Glasses + offer of $15 Upgrade Glasses; Free Glasses + offer of $30 Upgrade Glasses. Spectacle purchase (main outcome) was assessed 6 months after randomization. Among 10,234 children screened, 882 (8.62%, mean age 10.6 years, 45.5% boys) were eligible and randomized: 257 (29.1%) at 37 schools to Control; 253 (28.7%) at 32 schools to Free Glasses; 187 (21.2%) at 31 schools to Free Glasses + $15 Upgrade; and 185 (21.0%) at 27 schools to Free Glasses +$30 Upgrade. Baseline ownership among these children needing glasses was 11.8% (104/882), and 867 (98.3%) children completed follow-up. Glasses purchase was significantly less likely when free glasses were given: Control: 59/250 = 23.6%; Free glasses: 32/252 = 12.7%, P = 0.010. Offering Upgrade Glasses eliminated this difference: Free + $15 Upgrade: 39/183 = 21.3%, multiple regression relative risk (RR) 0.90 (0.56-1.43), P = 0.65; Free + $30 Upgrade: 38/182 = 20.9%, RR 0.91 (0.59, 1.42), P = 0.69. Upgrade glasses can prevent reductions in glasses purchase when free spectacles are provided, providing important program income. ClinicalTrials.gov Identifier: NCT02231606.

The prevalence of abdominal obesity is increasing dramatically worldwide. This study aimed to estimate the current prevalence of abdominal obesity from the 2011 China Health and Nutrition Survey (CHNS) and compare the data with other countries. Waist circumference (WC) of 12,326 Chinese adults (aged 20 years or older) from the 2011 CHNS were analyzed by age group and region. Abdominal obesity was defined as a WC ≥90 cm for men and WC ≥80 cm for women based on World Health Organization (WHO) recommendations for Asians. In 2011, the age-adjusted mean WC was 85.9 cm (95% confidence interval [CI], 85.6-86.2 cm) for men and 80.7 cm (95% CI, 80.4-80.9 cm) for women. Based on the WHO recommendations, the age-adjusted prevalence of abdominal obesity was 44.0% (95% CI, 43.1%-44.8%) overall, 35.3% (95% CI, 34.1%-36.6%) in men, and 51.7% (95% CI, 50.5%-52.9%) in women. Moreover, the age-adjusted prevalence was 44.0% (95% CI, 42.7%-45.2%) in rural populations, 42.5% (95% CI, 40.7%-44.2%) in urban populations, and 45.2% (95% CI, 43.5%-46.9%) in megacity populations. The prevalence in China (35.3% for men and 51.7% for women) was lower than in Japan (50.8% for men) and the United States (43.5% for men and 64.7% for women). Similar results were observed when applying the criteria suggested by the Working Group on Obesity in China. In 2011, the age-adjusted prevalence of abdominal obesity in China was 35.3% in men and 51.7% in women. Copyright © 2017 The Authors. Production and hosting by Elsevier B.V. All rights reserved.

China's forests are characterized by young age, low carbon (C) density and a large plantation area, implying a high potential for increasing C sinks in the future. Using data of provincial forest area and biomass C density from China's forest inventories between 1994 and 2008 and the planned forest coverage of the country by 2050, we developed a stage-classified matrix model to predict biomass C stocks of China's forests from 2005 to 2050. The results showed that total forest biomass C stock would increase from 6.43 Pg C (1 Pg = 10(15) g) in 2005 to 9.97 Pg C (95% confidence interval: 8.98 ~ 11.07 Pg C) in 2050, with an overall net C gain of 78.8 Tg C yr(-1) (56.7 ~ 103.3 Tg C yr(-1); 1 Tg = 10(12) g). Our findings suggest that China's forests will be a large and persistent biomass C sink through 2050.

The socioeconomic costs of Alzheimer's disease (AD) in China and its impact on global economic burden remain uncertain. We collected data from 3098 patients with AD in 81 representative centers across China and estimated AD costs for individual patient and total patients in China in 2015. Based on this data, we re-estimated the worldwide costs of AD. The annual socioeconomic cost per patient was US $19,144.36, and total costs were US $167.74 billion in 2015. The annual total costs are predicted to reach US $507.49 billion in 2030 and US $1.89 trillion in 2050. Based on our results, the global estimates of costs for dementia were US $957.56 billion in 2015, and will be US $2.54 trillion in 2030, and US $9.12 trillion in 2050, much more than the predictions by the World Alzheimer Report 2015. China bears a heavy burden of AD costs, which greatly change the estimates of AD cost worldwide. Copyright © 2017 the Alzheimer's Association. Published by Elsevier Inc. All rights reserved.

2017-12-08

The MODIS instrument aboard NASA's Aqua satellite flew over Typhoon Soudelor on Aug. 7, 2015, at 4:40 UTC (12:40 a.m. EDT) as it was approaching Taiwan. Credits: NASA Goddard's MODIS Rapid Response Team Clouds in Typhoon Soudelor's western quadrant were already spreading over Taiwan early on August 7 when NASA's Aqua satellite passed overhead. Soudelor is expected to make landfall and cross central Taiwan today and make a second landfall in eastern China. NASA satellite imagery revealed that Soudelor's eye "opened" five more miles since August 4. On Aug. 7 at 4:40 UTC (12:40 a.m. EDT) the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Aqua satellite captured a visible-light image of Typhoon Soudelor as its western quadrant began brushing eastern Taiwan. The MODIS image showed Soudelor's 17-nautical-mile-wide eye and thick bands of powerful thunderstorms surrounded the storm and spiraled into the center. Just three days before, the eye was 5 nautical miles smaller when the storm was more intense. On Aug. 4 at 4:10 UTC (12:10 a.m. EDT) Aqua's MODIS image showed the eye was 12-nautical-mile-wide eye. At 1500 UTC (11 a.m. EDT) on August 7, 2015, the Joint Typhoon Warning Center (JTWC) noted that Typhoon Soudelor's maximum sustained winds increased from 90 knots (103.6 mph/166.7 kph) to 105 knots (120.8 mph / 194.5 kph). It was centered near 23.1 North latitude and 123.2 East longitude, about 183 nautical miles (210.6 miles/338.9 km) southeast of Taipei, Taiwan. It was moving to the west-northwest at 10 knots (11.5 mph/18.5 kph). For warnings and watches for Taiwan, visit the Central Weather Bureau website: www.cwb.gov.tw/eng/.

Tan, Tony Xing

2014-01-01

In this study, the culture-gene co-evolutionary theory of mental disorders was used to test the hypothesis that major depression was less prevalent in China-to-US immigrants who migrated to the US as adults than in US-born adult Chinese Americans. Data from the Collaborative Psychiatric Epidemiology Surveys (CPES) were extracted for secondary data analyses on the rates of major depression disorder (MDD) and major depressive episode (MDE) in the two groups. Findings showed that for life time MDD, the rates for China-to-US immigrant and US-born Chinese were 5.3% and 7.9% for men and 8.5% and 33.1% for women. For 12-month MDD, the corresponding rates were 2.2% and 3.4% for men, and 4.7% and 12.6% for women. For life time MDE, the corresponding rates were 6.8% and 8.8% for men; for women the rates were 8.5% and 33.1%. For 12-month MDE, the rates were 2.2% and 4.4% for men; the rates were 4.7% and 12.6% for women. Controlling for age, education level, income, BMI, marital status, and income-to-needs ratio, China-to-US immigrant women remained less likely to have life time major depression than US-born Chinese American women. While the study has the strength of utilizing nationally representative datasets, the approach is limited as the data sources lack the capacity to investigate how the strength of connection with the collectivist culture might be related to major depression in the immigrant group.

In recent years, China has experienced severe and persistent air pollution associated with rapid urbanization and climate change. Three years' time series (January 2014 to December 2016) concentrations data of air pollutants including particulate matter (PM 2.5 and PM 10 ) and gaseous pollutants (SO 2 , NO 2 , CO, and O 3 ) from over 1300 national air quality monitoring sites were studied to understand the severity of China's air pollution. In 2014 (2015, 2016), annual population-weighted-average (PWA) values in China were 65.8 (55.0, 50.7) μg m -3 for PM 2.5 , 107.8 (91.1, 85.7) μg m -3 for PM 10 , 54.8 (56.2, 57.2) μg m -3 for O 3 _8 h, 39.6 (33.3, 33.4) μg m -3 for NO 2 , 34.1 (26, 21.9) μg m -3 for SO 2 , 1.2 (1.1, 1.1) mg m -3 for CO, and 0.60 (0.59, 0.58) for PM 2.5 /PM 10 , respectively. In 2014 (2015, 2016), 7% (14%, 19%), 17% (27%, 34%), 51% (67%, 70%) and 88% (97%, 98%) of the population in China lived in areas that meet the level of annual PM 2.5 , PM 10 , NO 2 , and SO 2 standard metrics from Chinese Ambient Air Quality Standards-Grade II. The annual PWA concentrations of PM 2.5 , PM 10 , O 3 _8 h, NO 2 , SO 2 , CO in the Northern China are about 40.4%, 58.9%, 5.9%, 24.6%, 96.7%, and 38.1% higher than those in Southern China, respectively. Though the air quality has been improving recent years, PM 2.5 pollution in wintertime is worsening, especially in the Northern China. The complex air pollution caused by PM and O 3 (the third frequent major pollutant) is an emerging problem that threatens the public health, especially in Chinese mega-city clusters. NOx controls were more beneficial than SO 2 controls for improvement of annual PM air quality in the northern China, central, and southwest regions. Future epidemiologic studies are urgently required to estimate the health impacts associated with multi-pollutants exposure, and revise more scientific air quality index standards.

Television (TV) use has been linked with poor eating behaviors and obesity in young people. This study examines the association between TV watching and paying attention to TV commercials with buying and requesting snacks seen on commercials, and eating snacks while watching TV among youth in China. Data from 1,552 participants (ages 6-17.99) in the 2004 China Health and Nutrition Survey were analyzed cross-sectionally. The 2004 China Health and Nutrition Survey was conducted in nine Chinese provinces. Most respondents (92.2%) reported watching TV; on average children (6-11.99 years old) and adolescents (12-17.99 years old) watched TV for 9-10 hours per week. Nearly half (42.9%) of all the respondents said they "sometimes" or "often" paid attention to TV commercials. Respondents who reported paying attention to commercials had higher odds of requesting snacks (odds ratio [OR] = 3.43; 95% confidence interval [CI] = 2.55-4.60) and buying snacks (OR = 2.73; 95% CI = 2.17-3.43) seen on TV, and eating snacks while watching TV (OR = 1.60; 95% CI = 1.23-2.07) than those who did not pay attention. However, frequency of watching TV was not significantly related to snacking. Attention to TV commercials for snack foods may be one of the factors affecting the increase in obesity among children and adolescents in China. Copyright 2010 Society for Adolescent Medicine.

This study was designed to examine the association between sleep duration and being overweight/obese in primary, middle, and high school students. This was a multiple cross-sectional study using data from the 2010 and 2014 National Survey on Students’ Constitution and Health (CNSSCH). A total of 23,602 students aged 7⁻18 years were enrolled in this study. The prevalence of being overweight and obese—stratified by age, gender, and sleep duration—in 2010 and 2014 were compared. Sleep duration was categorized as <7 h, ≥7 to 8 h, ≥8 to 9 h, and ≥9 h. Overweight and obesity were defined according to the cut-point criteria in China. Multivariable logistic regression results in 2010 and 2014 revealed that students sleeping <7 h and aged 7⁻12 years had an increased risk of becoming overweight/obese. In 2010, the adjusted prevalence ratios of overweight for 7⁻12-year-old students sleeping <9 h was 1.196 (95%CI: 1.004⁻1.424) and 13⁻15-year-old students sleeping <8 h was 1.265 (95%CI: 1.023⁻1.565). In 2014, the adjusted prevalence ratios of overweight and obesity for 7⁻12-year-old students sleeping <9 h were 1.295 (95%CI: 1.091⁻1.537) and 1.231 (95%CI: 1.045⁻1.449); 16⁻18-year-old students sleeping <7 h were 1.530 (95%CI: 1.239⁻1.888) and 1.585 (95%CI: 1.270⁻2.081). Our study revealed that different levels of sleep curtailment increased the risk of becoming overweight/obesity in different age groups of students.

2016-11-06

The paper is systematically explained the definition, contents of universal health coverage (UHC). Universal health coverage calls for all people to have access to quality health services they need without facing undue financial burden. The relationship between five main attributes, i.e., quality, efficiency, equity, accountability and resilience, and their 15 action plans has been explained. The nature of UHC is belonged to the State and government. The core function is commitment with equality. The whole-of-system method is used to promoting the health system reform. In China, the universal health coverage has been reached to the preliminary achievements, which include universal coverage of social medical insurance, basic medical services, basic public health services, and the provision of essential medicines. China has completed millennium development goals (MDG) and is being stepped to the sustainable development goals (SDG).

There is growing interest in the association between ambient air pollution and congestive heart failure (CHF), but research data from developing countries are very limited. The primary aim of this study was to examine the association between short-term exposure to air pollution and hospital admission for CHF in China. A time-stratified case-crossover study was conducted between 2014 and 2015 in 26 large Chinese cities among 105,501 CHF hospitalizations. Conditional logistic regression models were applied to estimate the percentage changes in CHF admissions in relation to per interquartile range increases in air pollutant concentrations. Air pollution was positively associated with CHF hospitalizations. An interquartile range increase in fine particulate, particulate matter less than 10 µm in aerodynamic diameter, sulfur dioxide, nitrogen dioxide, carbon monoxide, and ozone concentrations on the current day corresponded to 1.2% (95% confidence interval [CI] 0.5%, 1.8%), 1.3% (95% CI 0.5%, 2.0%), 1.0% (95% CI 0.2%, 1.7%), 1.6% (95% CI 0.6%, 2.5%), 1.2% (95% CI 0.5%, 1.9%), and 0.4% (95% CI -0.9%, 1.7%) increases in CHF admissions, respectively. In conclusion, our findings contribute to the limited scientific literature concerning the effects of air pollution on CHF risk for high-exposure settings typical in developing countries, which may have significant public health implications for prevention of CHF in China.

This study investigates the improvement of the prevention of mother-to-child transmission (PMTCT) of Human Immunodeficiency Virus (HIV) in China during 2004-2011. A clinic-based prospective study was conducted among HIV-positive pregnant women and their children in eight counties across China. Associated factors of mother-to-child transmission were analyzed using regression analysis. A total of 1,387 HIV+ pregnant women and 1,377 HIV-exposed infants were enrolled. The proportion of pregnant women who received HIV testing increased significantly from 45.1% to 98.9% during 2004-2011. Among whom, the proportion that received antiretroviral (ARV) prophylaxis increased from 61% to 96%, and the corresponding coverage in children increased from 85% to 97% during the same period. In contrast, single-dose nevirapine treatment during delivery declined substantially from 97.9% to 12.7%. Vertical transmission of HIV declined from 11.1% (95% confidence interval [CI]: 5.7-23.3%) in 2004 to 1.2% (95% CI: 0.1-5.8%) in 2011. Women who had a vaginal delivery (compared to emergency caesarian section (odds ratio [OR] = 0.46; 0.23-0.96)) and mothers on multi-ARVs (OR = 0.11; 0.04-0.29) were less likely to transmit HIV to their newborns. Increasing HIV screening enabled timely HIV care and prophylaxis to reduce vertical transmission of HIV. Early and consistent treatment with multi-ARVs during pregnancy is vital for PMTCT.

Hydatid worms, hosted by humans and animals, impose serious human health risk and cause significant livestock production loss. To better understand the disease infection status in Xinjiang, China, we investigated the disease epidemics in 4 livestock animals, i.e., cattle, sheep (both sheep and goat), camels, and horses, slaughtered at the abattoirs in Urumqi, Yining, Tacheng, and Altay areas. The results showed that the animals were infected at different rates, in the order of sheep (9.8%), cattle (8.4%), camels (6.8%), and horses (4.3%). The infection rates were found to be different between the abattoirs in various regions even for the same animals. For sheep, the rates increased significantly as the animals grew older. It was 1.9% before 1 year of age and increased to 8.2% in the age of 1-2 years, and further increased to 12.3% when the animals were 3-4 years old, and reached 17.2% when they were 5-6 year old. Sheep older than 6 years had an infection rate of 19.5%. This study demonstrates that the 4 livestock animals in the pastoral areas in Xinjiang were infected by the parasites to various extend. This study is the first systematic investigation of the hydatid worms in various livestock animals in Xinjiang, China, which provides epidemiological information about the infection of hydatid worms in livestock, and is valuable in developing strategies for prevention and control of the hydatid disease.

Abstract The purpose of this study was to examine the prevalence of Internet addiction in a nationally representative sample of Chinese elementary and middle school students and to investigate Internet addiction among Internet users with different usages. The data were from the National Children's Study of China (NCSC) in which 24,013 fourth- to ninth-grade students were recruited from 100 counties in 31 provinces in China. Only 54.2% of the students had accessed the Internet. According to the criteria of Young's Diagnostic Questionnaire (YDQ), an eight-item instrument, the prevalence of Internet addiction in the total sample was 6.3%, and among Internet users was 11.7%. Among the Internet users, males (14.8%) and rural students (12.1%) reported Internet addiction more than females (7.0%) and urban students (10.6%). The percentage of Internet addicts in elementary school students (11.5%) was not significantly lower than the percentage of middle school students (11.9%). There was no statistically significant difference between the four geographical regions (9.6%, 11.5%, 12.3%, 11.1%) characterized by different levels of economy, health, education, and social environment. As the frequency of Internet use and time spent online per week increased, the percentage of Internet addicts increased. When considering the location and purpose of Internet use, the percentage of Internet addicts was highest in adolescents typically surfing in Internet cafes (18.1%) and playing Internet games (22.5%).

Overweight and obesity are epidemic worldwide. Our previous study found that the prevalence of overweight and obesity in primary students is high. we sought to estimate whether the prevalence of overweight and obesity among university students is still high in China. A cross-sectional study was designed to collect the routine health screening data for university students in 2013. The height and weight of students were measured, and BMI was calculated with height and weight, we estimated the underweight and obesity prevalence of university students using by two references [Working Group on Obesity references in China (2004) and World Health Organization (WHO) criteria (2000)]. Depending on the China references used, the overall prevalence of underweight, overweight (including obesity) and obesity in male university students were 14.2%, 14.7% and 4.2%, respectively; in female university students were 27.5%, 4.4% and 0.6%, respectively. Depending on the WHO references used, the overall prevalence of underweight, overweight (including obesity) and obesity in male university students were 14.2%, 11.5% and 2.5%, respectively, in female university students were 27.5%, 2.4% and 0.3%, respectively. An interesting observation made was that the underweight prevalence of university students has an increasing trend, especially in female. The study showed that the prevalence of underweight in university students, especially in female students has become a critical health issue. Related department of school and government should pay more attention to student's physical health. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA. All rights reserved.

Can China's health care be transplanted without China's economic policies?

PubMed

Blendon, R J

1979-06-28

China's economic policies of the past 25 years have shaped its present health-care system. China's leadership has decided to have neither a national health-insurance system nor a national health service. Instead, it decided that its health system would mirror the workings of its industrial and agricultural system. Decisions to minimize imports, ban private economic activity, assign university graduates on a compulsory basis, control wages, maintain a large domestic standing army and prevent professions or universities from acquiring independent status led directly to the present system of medical care. Consequently, transplantation of China's striking achievements in health-care delivery to the United States or other countries is unlikely to occur in the absence of transfer of the underlying economic policies.

Many studies have examined childhood and adolescent obesity, but few have examined young adults and the effect of their home and current living environments on prevalence rates. The present study explores contextual factors affecting overweight and obesity among university students in China and, in particular, focuses on how the SES-obesity relationship varies across different geographical contexts. Participants were 11,673 students, who were identified through a multistage survey sampling process conducted in 50 universities. Individual data was obtained through a self-administered questionnaire, and contextual variables were retrieved from a national database. Multilevel logistic regression models were used to examine urban and regional variations in overweight and obesity. Overall the prevalence of overweight and obesity in the study sample was 9.5% (95% CI 7.7, 11.3%). After controlling for individual factors, both attributes of the home location (regional GDP per capita and rurality) and the current university location (city population) were found to be important, thus suggesting that the different origins of students affect current levels of obesity. At the individual level, while students with more financial resources were more likely to be obese, the extent of this relationship was highly dependent upon area income and city size. The results of this study add important insights about the role of contextual factors affecting overweight and obesity among young adults and indicate a need to take into account both past as well as present environmental influences when considering the role of contextual factors in models of the nutrition transition.

Although many studies have been conducted in recent years on the emissions of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs) at the large regional (such as East Asia) and national scales, relatively few studies have been conducted for cities or metropolitan areas. In this study, 192 air samples were collected in the Pearl River Delta (PRD) region of China in November 2010. The atmospheric mixing ratios of six halocarbons were analyzed, including trichlorofluoromethane (CFC-11, CCl3F), dichlorodifluoromethane (CFC-12, CCl2F2), monochlorodifluoromethane (HCFC-22, CHClF2), 1,1-dichloro-1-fluoroethane (HCFC-141b, CH3CCl2F), 1-dichloro-1,1-fluoroethane (HCFC-142b, CH3CClF2), and 1,1,1,2-tetrafluoroethane (HFC-134a, CH2FCF3), and their emissions were estimated based on an interspecies correlation method using HCFC-22 as the reference species. The results showed no significant change in the regional concentration and emission of CFC in the past 10years, suggesting that the continuous regional emission of CFC has had no significant effect on the CFC regional concentration in the PRD region. Concentrations and emissions of HCFCs and HFCs are significantly higher compared to previous research in the PRD region (P<0.05). The largest emission was for HCFC-22, most likely due to its substitution for CFC-12 in the industrial and commercial refrigeration subsector, and the rapid development of the room air-conditioner and extruded polystyrene subsectors. The PRD's ODP-weighted emissions of the target HCFCs provided 9% (7-12%) of the national emissions for the corresponding species. The PRD's GWP-weighted emissions of the target HCFCs and HFC-134a account for 10% (7-12%) and 8% (7-9%), respectively, of the national emissions for the corresponding species, and thus are important contributions to China's total emissions. © 2013 Elsevier B.V.

Quantitatively evaluating the effects of adjusting cropping systems on the utilization efficiency of climatic resources under climate change is an important task for assessing food security in China. To understand these effects, we used daily climate variables obtained from the regional climate model RegCM3 from 1981 to 2100 under the A1B scenario and crop observations from 53 agro-meteorological experimental stations from 1981 to 2010 in Northeast China. Three one-grade zones of cropping systems were divided by heat, water, topography and crop-type, including the semi-arid areas of the northeast and northwest (III), the one crop area of warm-cool plants in semi-humid plain or hilly regions of the northeast (IV), and the two crop area in irrigated farmland in the Huanghuaihai Plain (VI). An agro-ecological zone model was used to calculate climatic potential productivities. The effects of adjusting cropping systems on climate resource utilization in Northeast China under the A1B scenario were assessed. The results indicated that from 1981 to 2100 in the III, IV and VI areas, the planting boundaries of different cropping systems in Northeast China obviously shifted toward the north and the east based on comprehensively considering the heat and precipitation resources. However, due to high temperature stress, the climatic potential productivity of spring maize was reduced in the future. Therefore, adjusting the cropping system is an effective way to improve the climatic potential productivity and climate resource utilization. Replacing the one crop in one year model (spring maize) by the two crops in one year model (winter wheat and summer maize) significantly increased the total climatic potential productivity and average utilization efficiencies. During the periods of 2011-2040, 2041-2070 and 2071-2100, the average total climatic potential productivities of winter wheat and summer maize increased by 9.36%, 11.88% and 12.13% compared to that of spring maize, respectively. Additionally, compared with spring maize, the average utilization efficiencies of thermal resources of winter wheat and summer maize dramatically increased by 9.2%, 12.1% and 12.0%, respectively. The increases in the average utilization efficiencies of precipitation resources of winter wheat and summer maize were 1.78 kg hm-2 mm-1, 2.07 kg hm-2 mm-1 and 1.92 kg hm-2 mm-1 during 2011-2040, 2041-2070 and 2071-2100, respectively. Our findings highlight that adjusting cropping systems can dominantly contribute to utilization efficiency increases of agricultural climatic resources in Northeast China in the future.

Since the first outbreak of human infection with avian influenza A (H7N9) virus was identified in 2013, five seasonal outbreaks have occurred in China. The fifth outbreak started earlier than usual. A sudden increase in cases of human infection with avian influenza A (H7N9) virus has been reported in China since September 2016, and the number of cases reported in this season is exceeding that reported in previous seasons. This increase in the number of new cases of H7N9 infection has caused domestic and international concern. This paper summarizes the current prevalence of H7N9 in China and it also discusses measures that China has taken to control this outbreak. This paper also describes steps China must take in the future. This paper can serve as a reference for prevention and control of H7N9 outbreaks around the world.

To evaluate the screening practices and preparticipation evaluation (PPE) forms used to identify college athletes at risk for the female athlete triad (triad). Phone and/or e-mail survey. National Collegiate Athletic Association (NCAA) Division I universities. All 347 NCAA Division I universities were invited to participate in a survey, with 257 participating in the survey (74%) and 287 forms collected (83%). Information about the nature of the PPE was requested from team physicians and certified athletic trainers during a phone or e-mail survey. In addition, a copy of their PPE form was requested to evaluate for inclusion of the 12 items recommended by the Female Athlete Triad Coalition for primary screening for the triad. All 257 universities (100%) required a PPE for incoming athletes; however, only 83 universities (32%) required an annual PPE for returning athletes. Screening was performed on campus at 218 universities (85%). Eleven universities (4%) were using the recently updated fourth edition PPE. Only 25 universities (9%) had 9 or more of the 12 recommended items included in their forms, whereas 127 universities (44%) included 4 or less items. Relevant items that were omitted from more than 40% of forms included losing weight to meet the image requirements of a sport; using vomiting, diuretics, and/or laxatives to lose weight; and the number of menses experienced in the past 12 months. The current PPE forms used by NCAA Division I universities may not effectively screen for the triad.

Myelin basic protein (MBP) is an essential structure involved in the generation of central nervous system (CNS) myelin. Myelin shape has been described as liquid crystal structure of biological membrane. The interactions of MBP with monolayers of different lipid compositions are responsible for the multi-lamellar structure and stability of myelin. In this paper, we have designed MBP-incorporated model lipid monolayers and studied the phase behavior of MBP adsorbed on the plasma membrane at the air/water interface by thermodynamic method and atomic force microscopy (AFM). By analyzing the pressure-area (π-A) and pressure-time (π-T) isotherms, univariate linear regression equation was obtained. In addition, the elastic modulus, surface pressure increase, maximal insertion pressure, and synergy factor of monolayers were detected. These parameters can be used to modulate the monolayers binding of protein, and the results show that MBP has the strongest affinity for 1,2-dipalmitoyl-sn-glycero-3- phosphoserine (DPPS) monolayer, followed by DPPC/DPPS mixed and 1,2-dipalmitoyl-sn-glycero-3-phospho-choline (DPPC) monolayers via electrostatic and hydrophobic interactions. AFM images of DPPS and DPPC/DPPS mixed monolayers in the presence of MBP (5 nM) show a phase separation texture at the surface pressure of 20 mN/m and the incorporation of MBP put into the DPPC monolayers has exerted a significant effect on the domain structure. MBP is not an integral membrane protein but, due to its positive charge, interacts with the lipid head groups and stabilizes the membranes. The interaction between MBP and phospholipid membrane to determine the nervous system of the disease has a good biophysical significance and medical value.

We evaluated the occurrence and distribution of 12 antibiotics from the sulfonamide (SAs), fluoroquinolone (FQs) and tetracycline (TCs) groups in the Weihe River, North China. The total antibiotic concentrations in surface water, pore water, and sediment samples ranged from 11.1 to 173.1 ng/L, 5.8 to 103.9 ng/L, and 9.5 to 153.4 μg/kg, respectively. The values of the sediment-water partitioning coefficient in the Weihe River varied widely, from not detected to 943, 2213, and 2405 L/kg for SAs, FQs, and TCs, respectively. The values of the partitioning coefficients between sediment and surface water were generally lower than those between sediment and pore water, which indicated ongoing inputs to the water. The risk assessment showed that there were relatively high ecological risks to aquatic algae in this area from sulfamethoxazole, norfloxacin, tetracycline, ofloxacin, and ciprofloxacin.

To acquire epidemiologic data on drug-resistant tuberculosis (DR TB) among children, a major cause of illness and death for this population, we conducted a retrospective study of 2006–2015 data from 36 TB prevention and control institutions in Shandong Province, China. A total of 14,223 new TB cases, among which children (<18 years of age) accounted for only 5.5%, were caused by culture-confirmed Mycobacterium tuberculosis. Among children with TB, 18.9% had DR TB and 6.9% had multidrug-resistant TB. Over the past decade, the percentage of DR TB; multidrug-resistant TB; and overall first-line drug resistance for isoniazid, rifampin, ethambutol, and streptomycin among children increased significantly (at least 12%). Understanding the long-term trends of DR TB among children can shed light on the performance of TB control programs, thereby contributing to global TB control. PMID:29047424

Listeria monocytogenes is among the most important foodborne pathogens, which can be isolated from bird feces. The aim of this study was to examine the prevalence, genotypes, virulence factors and drug-resistance characteristics of L. monocytogenes isolated from the black-headed gull in Kunming, China. Serotypes and virulence genes were identified by polymerase chain reaction. Pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST) methods were used to describe the genetic characteristics of all positive isolates. Furthermore, all L. monocytogenes isolates were tested for antimicrobial susceptibility by disk diffusion method. All isolates were positive for inlA, inlB, plcB, prfA, iap, actA and hly genes. Serotyping showed the isolates belonged to serotype 1/2b (2/9, 22%), 1/2c (3/9, 33%), and 4a (4/9, 44%). PFGE showed 4 different pulsotypes (PTs), and MLST differentiated the 9 isolates into 4 sequence types (STs), ST3 (1), ST5 (1), ST35 (3) and ST201 (4). The result of antimicrobial susceptibility revealed that all isolates were naturally sensitive to most antibiotics. The L. monocytogenes isolates had pathogenic potential. There is a potential infection risk for people who come to frequent contact with black-headed gulls in Kunming. Hence, it is necessary to conduct surveillance of L. monocytogenes in the migratory black-headed gulls, which would be valuable to prevent listeriosis in local residents and tourists.

William Band (1906-1993) has been widely remembered by his American colleagues and students as ``a fine physicist and teacher,'' who taught at Washington State University in Pullman between 1949 and 1971 and authored Introduction to Quantum Statistics (1954) and Introduction to Mathematical Physics (1959). Not many, however, knew much about Band's early career, which was very ``uncommon and eventful.'' Born in England, Band graduated from University of Liverpool in 1927 with an MsSc degree in physics. Instead of pursuing his Ph.D. at Cambridge, he chose to teach physics at Yenching University, a prestigious Christian university in Beijing, China. Arriving in 1929, Band established his career at Yenching, where he taught and researched the theory of relativity and quantum mechanics, pioneered the study on low-temperature superconductivity in China, founded the country's first graduate program in physics, and chaired the Physics Department for 10 years until he fled from Yenching upon hearing of the attack on Pearl Harbor. It took him two years to cross Japanese occupied areas under the escort of the Communist force; he left China in early 1945. This presentation will explore Band's motivation to work in China and his contributions to the Chinese physics research and education.

As the largest funding agency of natural science of China, the National Natural Science Foundation of China (NSFC) has made great efforts in promoting the development of diabetic nephropathy (DN) research in recent years. The aim of the current study is to summarize the diabetic nephropathy research in China by analyzing NSFC-funded projects. Data on all projects in the DN field funded by NSFC from 1986 to 2013 were collected. The funding tendency, funding areas, and hotspots in the DN field, and major research institutions, were analyzed. As one output of this support, outstanding research groups in China, and their representative studies, are also highlighted. From 1986 to 2013, the NSFC has funded a total of 248 projects in the DN field, with a total funding amount of 91.5 million RMB (US$14.9 million). A rapid increase could be seen in the past 5 years, with an average annual 30% increase in projects numbers and a 52% increase in funding amount. All fields in DN research have been covered by the NSFC, including etiology, pathophysiology, diagnostics, and therapeutics. Along with increased funding of the DN research, there has been a growth in the papers published in Science Citation Index journals by Chinese scholars. In the past decade, the funding scale and funding budget have increased dramatically. Benefiting from this, DN research in China has also made considerable progression. © 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

A high-contrast grating (HCG) focusing reflector providing phase front control of reflected light and high reflectivity is proposed and fabricated. Basic design rules to engineer this category of structures are given in detail. A 1550 nm TM polarized incident light of 11.86 mm in focal length and 0.8320 in reflectivity is obtained in experiment. The wavelength dependence of the fabricated HCGs from 1530 nm to 1580 nm is also tested. The test results show that the focal length is in the range of 11.81-12 mm, which is close to the designed focal length of 15 mm. The reflectivity is almost above 0.56 within a bandwidth of 50 nm. At a distance of 11.86 mm, the light is focused to a round spot with the highest concentration, which is much smaller than the size of the incident beam. The FWHM of the reflected light beam decreases to 120 nm, and the intensity increases to 1.18.

At present, the diagnosis-related groups-based prospective payment system (DRG-PPS) that has been implemented in China is merely a prototype called the simplified DRG-PPS, which is known as the 'ceiling price for a single disease'. Given that studies on the effects of a simplified DRG-PPS in China have usually been controversial, we aim to synthesize evidence examining whether DRGs can reduce medical costs and length of stay (LOS) in China. Data were searched from both Chinese [Wan Fang and China National Knowledge Infrastructure Database (CNKI)] and international databases (Web of Science and PubMed), as well as the official websites of Chinese health departments in the 2004-2016 period. Only studies with a design that included both experimental (with DRG-PPS implementation) and control groups (without DRG-PPS implementation) were included in the review. The studies were based on inpatient samples from public hospitals distributed in 12 provinces of mainland China. Among them, 80.95% (17/21) revealed that hospitalization costs could be reduced significantly, and 50.00% (8/16) indicated that length of stay could be decreased significantly. In addition, the government reports showed the enormous differences in pricing standards and LOS in various provinces, even for the same disease. We conclude that the simplified DRGs are useful in controlling hospitalization costs, but they fail to reduce LOS. Much work remains to be done in China to improve the simplified DRG-PPS. © The Author 2017. Published by Oxford University Press on behalf of Royal Society of Tropical Medicine and Hygiene.

Introduction Improving the health and nutrition of women and children is a priority for Western China, where the economy is less developed. Due to the dynamic nature of lifestyle, modern food habits and nutrition, there is a need to update our limited knowledge and understanding of maternal lifestyle and nutritional status and their impact on pregnancy and infant health outcomes. While breast milk is the preferred feeding option, infant formula use is widespread in China. It is thus necessary to examine the effects of formula consumption on growth and morbidity. Methods and analysis This is an ongoing prospective cohort study started in 2015 in Chengdu, Sichuan Province. A sample of 1901 pregnant women at 15–20 weeks of gestation were recruited from four maternal and child health hospitals and are followed prospectively to 12 months post partum. Detailed information on maternal lifestyle and nutritional status, obstetric complications, pregnancy outcomes, infant feeding practices, illnesses of the mother and infant and growth trajectory is collected through personal interviews, anthropometric measures and medical records and local health management system records retrieval. Multilevel mixed regression models, adjusted for clustering, will be applied to investigate the association between various exposure variables of interest and the longitudinal outcomes, taking into account the correlated data structure and the nesting of observations. Kaplan-Meier test and Cox regression analysis will be used to analyse the time-to-event data. Ethics and dissemination Ethical approval has been obtained from the ethics committee of West China School of Public Health, Sichuan University and the Human Research Ethics Committee of Curtin University. Results will be presented at national and international conferences and published in peer-reviewed journals. PMID:28630084

Japan Sea is a marginal sea located on the rim of the western Pacific, connecting with the open ocean via key straits with sill depths of less than 130 m, whichis close to the maximum drop of sea level during the Last Glacial Maximum (LGM). Tsushima Strait connects modern JS with neighboring seas and Tsushima Warm Current (TWC), the only warm current flowing into the JS, reaches the northern JS where the cold saline deep wate is formed. Previous studies show that only northern Tsugaru Strait was opened during the last deglaciation, indicating different pattern of water mass exchange between JS and adjacent seas. Few paleoceanographic reconstructions in the southern JS are available to reconstruct the history of inflow of the TWC and deep ventilation. Radiolaria comprises shallow to deep water dwellers, sensitive response to changes in sea water physical and chemical states. It is well known for being preserved in the deep-sea sediments of the North Pacific. In order to decipher the changes of paleoceanography in the JS, here we investigate SST, SSS, deep ventilation using radiolarian assemblages recorded in core KCES1 recovered from the Ulleung Basin. We identified total 108 taxa which have been counted and divided into three categories: TWC, low-salinity and deep water taxa. Changes in radiolaria reveal that the paleoceanographic conditions has changed drastically during the last glacial period. The dominance of low-salinitytaxa indicates low SSS in JS during LGM. For older interval (24-46 ka), low-salinity taxa and TWC taxa could be identified, suggesting both East China Sea Coastal Water, whose volume is higher than Holocene, and TWC flow into the JS. The TWC taxa start to increase at 19 ka, also indicated by negative excursion of TOC δ13C due to the re-open of the Tsushima Strait, coincident with the 19 ka-MWP. The increasing abundance of low-salinity taxa during the B/A warm period, indicated an enhanced influence of river discharge forced by EASM. The enhanced deep ventilation occurred abruptly at 17 ka, caused by the sink of cold and saline water into the deep during the HS 1. While between 13 and 12 ka, high abundance of C.davisiana, one of the dominant species of deep water, inferring the strongest ventilation corresponding to the YD-like event. High abundance of TWC taxa shows the TWC re-enters into the JS during 9-7 ka.

Background and aim The purpose of this study was to describe the characteristics and prevalence of Internet addiction (IA) in adolescents so as to provide a scientific basis for the communities, schools, and families. Methods We conducted a survey by randomized cluster sampling on 5,249 students, grades ranging from 7 to 12, in Anhui province, People’s Republic of China. The questionnaire consisted of general information and IA test. Chi-square test was used to compare the status of IA disorder (IAD). Results In our results, the overall detection rate of IAD and non-IAD in students was 8.7% (459/5,249) and 76.2% (4,000/5,249), respectively. The detection rate of IAD in males (12.3%) was higher than females (4.9%). The detection rate of IAD was statistically different between students from rural (8.2%) and urban (9.3%) areas, among students from different grades, between students from only-child families (9.5%) and non-only-child families (8.1%), and among students from different family types. Conclusion Prevalence of IA is high among Chinese adolescents. IAD has more effect on male students, single-child families, single-parent families, and higher grade students. We should take more care of male students, only-child students, and students living with their fathers, and related education should be strengthen for susceptible subjects of IDA. PMID:27621633

Jin, Yinzi; Hou, Zhiyuan; Zhang, Donglan

2016-01-01

Background China is reforming and restructuring its health insurance system to achieve the goal of universal coverage. This study aims to understand the determinants of public, private and multiple insurance coverage among people of retirement-age in China. Methods We used data from the China Health and Retirement Longitudinal Survey 2011 and 2013, a nationally representative survey of Chinese people aged 45 and over. Multinomial logit regression was performed to identify the determinants of public, private and multiple health insurance coverage. We also conducted logit regression to examine the association between public insurance coverage and demand for private insurance. Results In 2013, 94.5% of this population had at least one type of public insurance, and 12.2% purchased private insurance. In general, we found that rural residents were less likely to be uninsured (Relative Risk Ratio (RRR) = 0.40, 95% Confidence Interval (CI): 0.34–0.47) and were less likely to buy private insurance (RRR = 0.22, 95% CI: 0.16–0.31). But rural-to-urban migrants were more likely to be uninsured (RRR = 1.39, 95% CI: 1.24–1.57). Public health insurance coverage may crowd out private insurance market (Odds Ratio = 0.55, 95% CI: 0.48–0.63), particularly among enrollees of Urban Resident Basic Medical Insurance. There exists a huge socioeconomic disparity in both public and private insurance coverage. Conclusion The migrants, the poor and the vulnerable remained in the edge of the system. The growing private insurance market did not provide sufficient financial protection and did not cover the people with the greatest need. To achieve universal coverage and reduce socioeconomic disparity, China should integrate the urban and rural public insurance schemes across regions and remove the barriers for the middle-income and low-income to access private insurance.

Peer Support and Adolescents' Physical Activity: The Mediating Roles of Self-Efficacy and Enjoyment.

PubMed

Chen, Han; Sun, Haichun; Dai, Jun

2017-06-01

The present study aimed to contrast the mediating magnitude of self-efficacy and enjoyment connecting peer support and adolescents' physical activity (PA). Participants were 9th-12th grade students ( N  = 409; 56.5% boys) who were randomly chosen from six public schools located in Fuzhou city in southeast China. The bootstrapping method in structural equation modeling was conducted to examine the direct and indirect effects of peer support on adolescents' PA. Peer support did not directly impact PA. Rather, peer support indirectly influenced PA through either self-efficacy or enjoyment, with self-efficacy demonstrating a stronger mediating effect. Additionally, we found a significant serial mediating effect with enjoyment, and self-efficacy sequentially mediated the relationship between peer support and PA. The findings highlight the role of self-efficacy and enjoyment as mediators connecting peer support and PA. Self-efficacy seems to be more important, as it demonstrated a significantly greater mediating effect. © The Author 2017.

We estimated the potential impact of an investigational 9-valent human papillomavirus (HPV) vaccine (HPVs 6/11/16/18/31/33/45/52/58) in HPV-related cervical disease in Brazil, Mexico, India and China, to help to formulate recommendations on cervical cancer prevention and control. Estimations for invasive cervical cancer (ICC) were based on an international study including 1356 HPV-positive cases for the four countries altogether, and estimations for precancerous cervical lesions were extracted from a published meta-analysis including 6 025 HPV-positive women from the four mentioned countries. Globocan 2012 and 2012 World Population Prospects were used to estimate current and future projections of new ICC cases. Combined proportions of the 9 HPV types in ICC were 88.6% (95%CI: 85.2-91.3) in Brazil, 85.7% (82.3-88.8) in Mexico, 92.2% (87.9-95.3) in India and 97.3% (93.9-99.1) in China. The additional HPV 31/33/45/52/58 proportions were 18.8% (15.3-22.7) in Brazil, 17.6% (14.2-21.2) in Mexico, 11.3% (7.5-16.1) in India and 11.9% (7.5-17.2) in China. HPV6 and 11 single types were not identified in any of the samples. Proportion of the individual 7 high risk HPV types included in the vaccine varied by cytological and histological grades of HPV-positive precancerous cervical lesions. HPV 16 was the dominant type in all lesions, with contributions in low grade lesions ranging from 16.6%(14.3-19.2) in Mexico to 39.8% (30.0-50.2) in India, and contributions in high grade lesions ranging from 43.8% (36.3-51.4) in Mexico to 64.1% (60.6-67.5) in Brazil. After HPV 16, variations in other majors HPV types were observed by country, with an under representation of HPV 18 and 45 compared to ICC. The addition of HPVs 31/33/45/52/58 to HPV types included in current vaccines could increase the ICC preventable fraction in a range of 12 to 19% across the four countries, accounting the 9-types altogether 90% of ICC cases. Assuming the same degree of efficacy of current vaccines, the implementation of the 9-valent HPV vaccine in Brazil, Mexico, India and China would substantially impact on the reduction of the world cervical cancer burden.

This study was aimed to estimate the prevalences of chlamydia (CT) and gonococcal (NG) infections and explore risk factors associated with the CT infection among women in Shenzhen, China. We collected socio-demographic and clinical data from women (aged 20-60) and determined positivity of CT or NG by nucleic acid amplification test (NAAT) with self-collected urine specimens. We estimated prevalence of CT and NG and determined risk factors associated with CT infection. Among 9,207 participants, 4.12% (95% confidence interval [CI], 3.71%-4.53%) tested positive for CT and 0.17% (95% CIs, 0.09%-0.25%) for NG. Factors significantly associated with CT infection included being an ethnic minority (ethnicity other than Han China) (Adjusted odds ratio [AOR], 1.9; 95% CI, 1.2-3.0), using methods other than condom for contraception (AOR, 1.5; 95% CI, 1.2-1.8), having a history of adverse pregnancy outcomes (AOR, 1.4; 95% CI, 1.1-1.8), and experiencing reproductive tract symptoms in the past three months (AOR, 1.3; 95% CI, 1.0-1.7). we found that CT infection is prevalent among women in Shenzhen, China and associated with both demographic and behavioral factors. A comprehensive CT screening, surveillance and treatment programme targeting this population is warranted.

Carbon monoxide (CO) concentration distribution, sea-to-air flux and microbial consumption rate constant, along with atmospheric CO mixing ratio, were measured in the East China Sea and the South Yellow Sea in summer. Atmospheric CO mixing ratios varied from 68 x 10(-9) -448 x 10(-9), with an average of 117 x 10(-9) (SD = 68 x 10(-9), n = 36). Overall, the concentrations of atmospheric CO displayed a decreasing trend from the coastal stations to the offshore stations. The surface water CO concentrations in the investigated area ranged from 0.23-7.10 nmol x L(-1), with an average of 2.49 nmol x L(-1) (SD = 2.11, n = 36). The surface water CO concentrations were significantly affected by sunlight. Vertical profiles showed that CO concentrations rapidly declined with depth, with the maximum values appearing in the surface water. CO concentrations exhibited obvious diurnal variations in the study area, with the maximum values being 6-40 folds higher than the minimum values. Minimal concentrations of CO all occurred before dawn. However, the maximal concentrations of CO occurred at noon. Marked diurnal variation in the concentrations of CO in the water column indicated that CO was produced primarily by photochemistry. The surface CO concentrations were oversaturated relative to the atmospheric concentrations and the saturation factors ranged from 1.99-99.18, with an average of 29.36 (SD = 24.42, n = 29). The East China Sea and the South Yellow Sea was a net source of atmospheric CO. The sea-to-air fluxes of CO in the East China Sea and the South Yellow Sea ranged 0.37-44.84 μmol x (m2 x d)(-1), with an average of 12.73 μmol x (m2 x d)(-1) (SD = 11.40, n = 29). In the incubation experiments, CO concentrations decreased exponentially with incubation time and the processes conformed to the first order reaction characteristics. The microbial CO consumption rate constants (K(co)) in the surface water ranged from 0.12 to 1.45 h(-1), with an average of 0.47 h(-1) (SD = 0.55, n = 5). A negative correlation between K(co) and salinity was observed in the present study.

The Working Group for Women in Physics in Taiwan was registered to the Physical Society of the Republic of China (PSROC) in December 1999 and was formally announced at the 2001 annual assembly of PSROC. In 2003 the group became a formal committee under PSROC. The current committee includes seven female and two male members. In the last 10 years, many milestones were achieved. In particular, the percentage of female physics faculties in universities and research institutes has increased to 12% from 8% within the last 10 years. In this paper we will present the results of our survey on the changes of the percentage of female physics faculties/students within the last 10 years and express our need to improve the working environment for female faculties in Taiwan in the future.

To outline the history of medical informatics education in the People's Republic of China, systematically analyze the current status of medical informatics education at different academic levels (bachelor's, master's, and doctoral), and suggest reasonable strategies for the further development of the field in China. The development of medical informatics education was divided into three stages, defined by changes in the specialty's name. Systematic searches of websites for material related to the specialty of medical informatics were then conducted. For undergraduate education, the websites surveyed included the website of the Ministry of Education of the People's Republic of China (MOE) and those of universities or colleges identified using the baidu.com search engine. For postgraduate education, the websites included China's Graduate Admissions Information Network (CGAIN) and the websites of the universities or their schools or faculties. Specialties were selected on the basis of three criteria: (1) for undergraduate education, the name of specialty or program was medical informatics or medical information or information management and information system; for postgraduate education, medical informatics or medical information; (2) the specialty was approved and listed by the MOE; (3) the specialty was set up by a medical college or medical university, or a school of medicine of a comprehensive university. The information abstracted from the websites included the year of program approval and listing, the university/college, discipline catalog, discipline, specialty, specialty code, objectives, and main courses. A total of 55 program offerings for undergraduate education, 27 for master's-level education, and 5 for PhD-level education in medical informatics were identified and assessed in China. The results indicate that medical informatics education, a specialty rooted in medical library and information science education in China, has grown significantly in that country over the past 10 years. Frequent changes in the specialty's name and an unclear identity have hampered the visibility of this educational specialty and impeded its development. There is a noticeable imbalance in the distribution of degree programs in medical informatics in different disciplines, with the majority falling under information management. There is also an uneven distribution of the specialty settings of medical informatics at the various academic levels (bachelor's, master's, and doctoral). In addition, the objectives and curriculum design of medical informatics education differ from one university to another and also from those of foreign universities or colleges. It is recommended that China (1) treat medical informatics as a priority "must-have" discipline to build in China, (2) establish its own independent, balanced degree programs, (3) set up a specialty of "medical informatics" under the "medicine" category, (4) explore curriculum integration with international medical informatics education, and (5) establish and improve medical informatics education system.

Antithyroid drug (ATD)-induced agranulocytosis is a rare but life-threatening disease. Clinical features of ATD-induced agranulocytosis and outcomes remain incompletely understood. Patients with clinically diagnosed ATD-induced agranulocytosis were retrospectively studied, involving 9690 patients who were referred for radioiodine treatment during a 15-year period (2000-2015) in China. There were 114 cases of agranulocytosis attributable to ATD included, and their clinical characteristics and therapy outcomes were analyzed. The female-to-male ratio of ATD-induced agranulocytosis was 10.4:1. The mean age (±standard deviation) of the patients with ATD-induced agranulocytosis was 41.7 ± 12.3 years. The methimazole and propylthiouracil doses given at the onset were 22.9 ± 8.0 mg/day and 253.6 ± 177.5 mg/day, respectively. ATD-induced agranulocytosis occurred in 45.1%, 74.3%, and 88.5% of patients within 4, 8, and 12 weeks of the onset of ATD therapy, respectively. Fever (78.9%) and sore throat (72.8%) were the most common symptoms when agranulocytosis was diagnosed. The mean recovery time of agranulocytosis was 13.41 ± 7.14 days. Recovery time in the granulocyte colony-stimulating factor (G-CSF)-treated group (12.7 ± 6.0 days) did not differ from that in the group not treated with G-CSF (16.4 ± 10.6 days; p = 0.144). Treatment with (131)I was successful in 87/98 patients (88.8%). The success rate of (131)I was equivalent (p = 1.000) between the groups receiving methimazole (88.2%, 75/85) and propylthiouracil (92.3%, 12/13). This largest single-institution study in China shows that ATD-induced agranulocytosis tends to occur within the first 12 weeks after the onset of ATD therapy. For patients with ATD-induced agranulocytosis, G-CSF does not improve the recovery time of agranulocytosis, and (131)I is an optimal treatment approach.

Nine organophosphate esters (OPEs) in airborne particles were measured during a cruise campaign over the northern South China Sea (SCS) from September to October 2013. The concentration of the total OPEs (∑OPEs) was 47.1-160.9 pg m(-3), which are lower than previous measurements in marine atmosphere environments. Higher OPE concentrations were observed in terrestrially influenced samples, suggesting that OPE concentrations were significantly influenced by air mass transport. Chlorinated OPEs were the dominant OPEs, accounting for 65.8-83.7% of the ∑OPEs. Tris-(2-chloroethyl) phosphate (TCEP) was the predominant OPE compound in the samples (45.0±12.1%), followed by tris-(1-chloro-2-propyl) phosphates (TCPPs) (28.8±8.9%). Dry particle-bound deposition fluxes ranged from 8.2 to 27.8 ng m(-2) d(-1) for the ∑OPEs. Moreover, the dry deposition input of the ∑OPEs was estimated to be 4.98 ton y(-1) in 2013 in a vast area of northern SCS. About half of the input was found to relate to air masses originating from China. Copyright © 2015 Elsevier Ltd. All rights reserved.

Constant surveillance of live poultry markets (LPMs) is currently the best way to predict and identify emerging avian influenza viruses (AIVs) that pose a potential threat to public health. Through surveillance of LPMs from 16 provinces and municipalities in China during 2014-2016, we identified 3,174 AIV-positive samples and isolated and sequenced 1,135 AIVs covering 31 subtypes. Our analysis shows that H5N6 has replaced H5N1 as one of the dominant AIV subtypes in southern China, especially in ducks. Phylogenetic analysis reveals that H5N6 arose from reassortments of H5 and H6N6 viruses, with the hemagglutinin and neuraminidase combinations being strongly lineage specific. H5N6 viruses constitute at least 34 distinct genotypes derived from various evolutionary pathways. Notably, genotype G1.2 virus, with internal genes from the chicken H9N2/H7N9 gene pool, was responsible for at least five human H5N6 infections. Our findings highlight H5N6 AIVs as potential threats to public health and agriculture. Copyright © 2016. Published by Elsevier Inc.

Influenza H9N2 subtype viruses and their reassortants (such as H7N9) are posing increasing threats to birds and humans in China. During 2009–2013, multiple novel subtype viruses with H9N2 original genes emerged in China. Yet, the genetic evolution of H9N2 viruses in various host organisms in China has not been systematically investigated since 2009. In the present study, we performed large-scale sequence analysis of H9N2 viral genomes from public databases, representing the spectrum of viruses isolated from birds, mammals and humans in China from 1994 to 2013, and updated the clade classification for each segment. We identified 117 distinct genotypes in 730 H9N2 viruses. We analyzed the sequences of all eight segments in each virus and found three important time points: the years 2000, 2006 and 2010. In the periods divided by these years, genotypic diversity, geographic distribution and host range changed considerably. Genotypic diversity fluctuated greatly in 2000 and 2006. Since 2010, a single genotype became predominant in poultry throughout China, and the eastern coastal region became the newly identified epidemic center. Throughout their 20-year prevalence in China, H9N2 influenza viruses have emerged and adapted from aquatic birds to chickens. The minor avian species and wild birds exacerbated H9N2 genotypes by providing diversified genes, and chickens were the most prevalent vector in which the viruses evolved and expanded their prevalence. It is the necessity for surveillance and disease control on live-bird markets, poultry farms and wild-bird habitats in China. PMID:29184157

A comparison of efficiency of birth control input between China and India.

PubMed

Liang, J; Wang, H

1994-01-01

Global world population in mid-1991 would have been 6.9% higher (an additional 366 million births) without the effective birth control programs in India and China. 260 million births in China and 110 million births in India were averted. These averted births relieved population pressure on the food supply. Without birth control, output would have decreased by 20% in China to 302 kg in 1991 and by 12% in India to 189 kg in 1991. Both India and China have between 1000 and 2000 married and fertile women per birth control worker. The manpower-input efficiency is higher by 2 times in China than in India, but the gap is closing. In China, public expenses for birth control include family planning operating expenses, family planning workers, and bonuses for single child families. World Bank estimation has determined the ratio of government to grassroots investment to be 1:2. Total investment in 1980 was RMB 1.4596 billion or about $10.00 per person. In 1980 the allowance was RMB 60.00 per year per single child family, and in 1989 the allowance should have been RMB 120.00 per year per family but was actually RMB 48.00 due to local poverty areas and low economic performance. Data were provided annually between 1971 and 1991 on total revenue, grassroots revenue, bonuses, foreign aid, and expenses per person. The expenses per person increased from RMB 2.46 in 1971 to 5.23 in 1991 or US $6.53 in 1990. Investment in birth control totaled over 21 years RMB 50.10186 billion (US $16.6557 billion), which included RMB 49.9696 from China and $40 million in foreign aid. The cost of preventing 259.585 births over this period was RMB 193.01 or US $64.16 per birth. Savings would also accrue from child rearing costs. Government savings would have amounted to RMB 3,461 billion in rural and urban areas, or 2 times China's gross national product in 1988. State costs amount to 36.5% and family costs amount to 63.5% of child rearing until 16 years of age in urban areas; the proportion in rural areas would be 20.03% and 79.97%. The prevention of 260 million births would have saved RMB 932.1 billion for the state and collectives and RMB 2,528.9 billion for families. Over 21 years, savings were RMB 50.1 billion by the state and RMB 932.1 billion by collectives. The efficiency yield would be 1:18.60 and including family savings 1:69.08. The ratio was computed for shadow prices and with a discount factor. For India, the efficiency yield was 1:57.37.

Based on the cancer registry data to analyze the mortality and survival of liver cancer in China. Liver cancer data of 2011 were retrieved from the National Cancer Registry Database.Liver cancer deaths were estimated using age-specific rate by areas and gender according to the national population in 2011. Mortality data from 22 cancer registries during 2000-2011 were used to analyze the mortality trend, and data from 17 cancer registries during 2003-2005 were used for survival analysis. The estimates of liver cancer deaths were about 322 thousand in 2011 with a crude mortality rate of 23.93/10(5).There was an increasing trend of crude mortality rate of liver cancer during 2000-2011 in 22 Chinese cancer registries with an average annual percentage change of 0.7% (95%CI: 0.2%-1.2%), 1.1% in urban and 0.4% in rural areas. After age standardization with Segi's population, the mortality rate was significantly decreased, with an APC of -2.3%, -1.9% in urban and -2.2% in rural populations. The 5-year age standardized relative survival was 10.1% (95%CI: 9.5% to 10.7%), and the 1-, 3- and the 5-year observed survival rates were 27.2%, 12.7%, and 8.9%, respectively. Liver cancer is a major cancer threatening people's lives and health in China, and the liver cancer burden is still high.

To provide up-to-date pubertal characteristics in a representative population of boys from both urban and rural areas of China. The China Puberty Research Collaboration enrolled 15 011 boys of Chinese Han ethnicity aged 6.0-18.9 years in eight regions including both urban and rural areas. Stages of genital and pubic hair development were assessed by trained physicians according to the Tanner method. Testicular volume was evaluated with a Prader orchidometer. Median age for onset of testicular volume of 4 mL or greater was 11.02 years. Median age for onset of genital (G2), pubic hair development (PH2) and spermarche was 11.24 years, 12.67 years and 14.32 years, respectively. Boys with BMI ≥ 85th percentile reached the onset of TV ≥ 4 ml (11.09 years), G2 (11.34 years) and G3 (13.01 years) later than boys with a normal BMI (10.95 years, 11.1 years and 12.88 years, respectively). Urban boys achieved pubertal milestones at an earlier age than rural peers except for G5 (13.4 vs 13.76 years) and PH5 (12.86 years vs 13.14 years). There is an asynchronous pattern in the onset of puberty among Chinese boys. Higher BMI is related to early pubertal onset but fast pubertal progression. Urban boys achieved onset of puberty earlier than rural boys in China.

Co-sleeping is associated with disturbance of the natural sleep pattern, including sleep fragmentation and daytime sleepiness. Nocturnal enuresis (NE) or bed-wetting, although benign, is a significant cause of distress to affected children and their caregiver(s). This study investigated the relationship between co-sleeping and NE in primary school children from China. Data from a previous sleep study of primary school children from 8 cities across China were analyzed. Multivariable regression analysis was performed to assess the relationship between co-sleeping and NE while controlling for a number of confounding factors. The prevalence of NE in co-sleeping and non-co-sleeping children in different age groups was evaluated. The prevalence of co-sleeping and NE in children aged 5 to 12 years was 22.8% and 4.6%, respectively. Co-sleeping was associated with a higher prevalence of NE in primary school age children (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.27-1.77; p < .001) after adjusting for confounding factors. The differences in the prevalence of NE between co-sleepers and non-co-sleepers were significant in the 9-year age group (OR, 1.49; 95% CI, 1.06-2.11; p = .025) and 11- to 12-year age group (OR, 3.16; 95% CI, 2.19-4.57; p < .001). Co-sleeping may increase the risk of NE in primary school children, particularly in those aged 11 to 12 years.

The loess-paleosol sequences in Shandong Province, East China, is an important aeolian archive, which can provide information for aeolian activity, palaeoclimatic change and sea level change in eastern coast of China since the last interglacial period. However, for so long, most of the studies about loess have been focused on the Chinese Loess Plateau, remaining many questions and disputes about the loess in East China. The Xianjingyuan (XJY) section on the TIA, Bohai Sea, is a representative aeolian section for islands off the eastern coast of China. In this study, optically stimulated luminescence (OSL) dating, particle size and magnetic susceptibility were applied to date and analysis the loess-paleosol sequences in this section. The results show that: (1) The OSL ages at the depths of 0.8 m, 2.5 m, and 3.9 m are 12.6 ± 1.0 ka, 19.2 ± 1.1 ka and 56.9 ± 2.6 ka, respectively, and the loess started to accumulate at ca. 86.5 ka according to the depositional rates (2) The loess accumulated mainly during the Marine Isotope Stage (MIS) 2, i.e., Last glacial maximum and deglaciation, MIS4 and MIS3b with higher depositional rate, coarser grain size, and higher magnetic susceptibility; while paleosol mainly developed during MIS3a, MIS3c and MIS5 with lower depositional rate, finer grain size and lower magnetic susceptibility. (3) The palaeoclimatic changes and aeolian sediments evolution were mainly controlled by the changes of East Asian summer monsoon and sea levels.

This study was conducted to estimate the prevalence of Toxoplasma gondii, Dirofilaria immitis, feline immunodeficiency virus (FIV), and feline leukemia virus (FeLV) infections among stray and pet cats in Lanzhou, northwest China, and to identify the influence of age, gender, and regions on seropositivity. T. gondii antibodies were examined in cat sera by the modified agglutination test (MAT). The circulating antigens of D. immitis and FeLV and specific antibodies to FIV were examined using kits commercially available. The overall prevalence of T. gondii, FIV, FeLV, and D. immitis was 19.34, 9.12, 11.33, and 3.04 %, respectively. For the genetic characterization of T. gondii genotypes in cats, genomic DNA was extracted from the seropositive cats and the T. gondii B1 gene was amplified using a semi-nested PCR. DNA samples giving positive B1 amplification were then genotyped using multilocus PCR-RFLP. Two T. gondii genotypes (ToxoDB#9 and ToxoDB#1) were identified. Results of the multivariate logistic regression analysis showed that older cats are more likely to be seropositive than juveniles for T. gondii, FIV, FeLV, and D. immitis. This is the first report of T. gondii genotypes in cats in northwest China. Moreover, the present study is the first study of retrovirus and D. immitis seroprevalence in cats in China. The results revealed that T. gondii, FIV, and FeLV infections are common in stray and pet cats in northwest China.

Alzheimer disease (AD) is the most frequent cause of dementia. AD diagnosis, progression, and treatment have not been analyzed nationwide in China. The primary aim of this study was to analyze demographic and clinical characteristics related to cognitive decline in AD patients treated at outpatient clinics in China.We performed a retrospective study of 1993 AD patients at 10 cognitive centers across 8 cities in China from March 2011 to October 2014. Of these, 891 patients were followed for more than 1 year.The mean age at diagnosis was 72.0 ± 10.0 years (range 38-96 years), and the mean age at onset of AD was 69.8 ± 9.5 years. Most patients (65.1%) had moderate to severe symptoms at the time of diagnosis, and mean Mini-Mental State Examination at diagnosis was 15.7 ± 7.7. AD patients showed significant cognitive decline at 12 months after diagnosis. Having more than 9 years of formal education was an independent risk factor related to rapid cognitive decline [odds ratio (OR) = 1.80; 95% confidence interval (95% CI): 1.11-2.91]. Early-onset AD patients experienced more rapid cognitive decline than late-onset patients (OR = 1.83; 95% CI: 1.09-3.06).Most AD patients in China had moderate to severe symptoms at the time of diagnosis and experienced significant cognitive decline within 1 year. Rapid cognitive decline in AD was related to having a higher educational level and younger age of onset.

Congenital uterine anomalies are associated with the highest incidence of reproductive failure and obstetric complications. This study aimed to summarize the clinical characteristics and prenatal outcome of pregnancy in women with congenital uterine malformations. This retrospective study evaluated the fertility and obstetric outcome of 116 inpatients with uterine malformations with pregnancy in Peking University Third Hospital from June 1998 to June 2009. A total of 270 randomly selected pregnant women with a previously confirmed normally shaped uterus as a control group. Student's t test and analysis of variance (ANOVA) were used to compare means for normally distributed variables. The analysis was carried out using the SPSS. Among 21 961 deliveries in Peking University Third Hospital, 116 (0.45%) were in women with uterine anomalies. A septate uterus was present in 43 (37.1%) and the uterus didelphys in 28 (24.2%) of the 116 women identified. Bicornuate uterus, arcuate and unicomate uterus were observed in 12 (10.3%), 18 (15.5%) and 15 (12.9%) patients, respectively. Patients with uterine anomalies had significantly higher rates of malpresentation (38.8%), preterm delivery (19.8%), and cesarean section (78.5%) compared with the group of women with a normal uterus. Patients with uterine anomalies had significantly lower mean birth-weight neonates and a significantly higher incidence of small for gestationalage (SGA) neonates; women with uterus didelphys more frequently required infertility treatment than patients with other uterine anomalies (P < 0.001). The rate of malpresentation was significantly higher in patients with septated uterus in comparison with patients with uterus unicorns (P < 0.05). Women with congenital uterinemal formation usually have higher incidence of complications during pregnancy and delivery. A septate uterus appears to be associated with poorer obstetric outcomes.

The Campylobacter species usually causes infection between humans and livestock interaction via livestock breeding. The studies of the Campylobacter species thus far in all clinical isolates were to show the many kinds of antibiotic phenomenon that were produced. Their integrons cause the induction of antibiotic resistance between bacterial species in the Campylobacter species. The bacterial strains from the diarrhea of pediatric patient which isolated by China Medical University Hospital storage bank. These isolates were identified by MALDI-TOF mass spectrometry. The anti-microbial susceptibility test showed that Campylobacter species resistant to cefepime, streptomycin, tobramycin and trimethoprim/sulfamethoxazole (all C. jejuni and C. coli isolates), ampicillin (89% of C. jejuni ; 75% of C. coli ), cefotaxime (78% of C. jejuni ; 100% of C. coli ), nalidixic acid (78% of C. jejuni ; 100% of C. coli ), tetracycline (89% of C. jejuni ; 25% C. coli ), ciprofloxacin (67% of C. jejuni ; 50% C. coli ), kanamycin (33% of C. jejuni ; 75% C. coli ) and the C. fetus isolate resisted to ampicillin, cefotaxime, nalidixic acid, tetracycline, ciprofloxacin, kanamycin by disc-diffusion method. The effect for ciprofloxacin and tetracycline of the Campylobacter species was tested using an E-test. The tet, erm , and integron genes were detected by PCR assay. According to the sequencing analysis (type I: dfr12 - gcuF - aadA2 genes and type II: dfrA7 gene), the cassette type was identified. The most common gene cassette type (type I: 9 C. jejuni and 2 C. coli isolates; type II: 1 C. coli isolates) was found in 12 class I integrase-positive isolates. Our results suggested an important information in the latency of Campylobacter species with resistance genes, and irrational antimicrobial use should be concerned.

Men who have sex with men (MSM) have become a high-risk group of HIV infection in China. To date, little is known regarding the psychological characteristics in Chinese MSM, especially the prevalence of suicidal ideation and attempts. A questionnaire survey was conducted on 2,250 MSM recruited from gay bars in 9 large cities in mainland China. Data on the prevalence of suicidal ideation and attempts as well as the underlying causes in the respondents were analyzed. A total of 1530 MSM responded to the question regarding previous suicidal ideation and attempts. Of these respondents, 26.01% had ever considered suicide and 12.55% actually attempted suicide at least once. Romantic gay relationship breakup was the number one cause of suicide behaviors, followed by self-objection to homosexuality, difficulties in finding gay partners or in getting used to heterosexual marriage life, sudden emotional hurts from unexpected events, illegal status of gay marriage in China and disclosure of homosexuality. The survey study has led to a better understanding of the factors contributing to suicide behaviors of MSM in China, which may have significant implications in developing preventive strategies against suicide behaviors in this unique group of individuals.

The heavy metal contents (Co, Cu, Fe, Mn, Ni, and Zn) of eight species of wild edible mushrooms from China were determined. The analyses were performed using inductively coupled plasma atomic emission spectrophotometry after microwave digestion. The contents of Co, Cu, Fe, Mn, Ni, and Zn in caps of mushroom samples were 0.7-7.2, 16.2-70.4, 371-1315, 12.5-29.8, 7.1-58.5, and 77.8-187.4 mg kg -1 dry matter (dm), respectively, while considerable differences were found to be 1.8-25.9, 9.8-36.3, 288-6762, 13.3-103.9, 5.9-78.7, and 38.7-118 mg kg -1 dm for stipes. The results indicated that higher levels of Co, Fe, and Ni were found in the mushrooms samples analyzed. Zinc and manganese levels were similar to previous reports, whereas Cu was lower than literature values. Correlation analysis suggested that significant correlations were found between the minerals determined and the greatest amount of contamination is associated with Co, Mn, Ni, and Fe. The results of this study indicate that heavy metal contents in mushroom species are mainly related to the mineral resources of sampling sites.

Lack of access to basic education leads to diminished individual and national capabilities, therewith furthering cycles of poverty. An equitable education system meeting basic learning needs represents not only a human right, but also a means for reducing poverty, promoting productivity, and sustaining development. The Government of China - the most populous developing nation, the majority of whose citizens live in rural areas - has been committed to universalizing nine-year compulsory education among school-aged children and eliminating illiteracy among youths and adults aged 15-45. This study examines lessons learned from China's efforts in these areas. It also reports on current challenges and trends in a new national initiative for achieving high-quality universal basic education by the year 2007.

Variability in drug response could result from a variety of genetic and environmental factors that are often hard to define or quantify. A number of studies demonstrated regional geographic variations in potency of neuromuscular blocking agents (NMBAs). The aim of our study was to compare dose-response and time-course-of-action of cisatracurium besylate, an NMBA eliminated via the Hoffman degradation, in two countries with different life habits, diet, and ambient conditions; being Han Chinese in China and Caucasians in Bosnia. Neuromuscular block of cisatracurium 20 µg kg(-1), followed by four incremental 10 µg kg(-1) doses, and the remainder of 100 µg kg(-1) was evaluated using the Relaxometer mechanomyograph (Groningen University, Groningen, The Netherlands). Dose-response curves were created using log-dose-probit-response transformation. There were no significant differences in cisatracurium mean (95% confidence intervals) ED(50), ED(90), and ED(95) (effective doses for 50%, 90%, and 95% first twitch depression) in Caucasian [39.1 (35.7-42.3), 50.6 (45.5-54.3), and 54.4 (49.8-58.9) µg kg(-1)] compared with Chinese patients [39.2 (35.1-43.1), 52.4 (47.9-56.8), and 56.9 (52.8-61.9) µg kg(-1)], respectively. There were no significant differences in mean (sd) Dur(25) and Dur(0.9) (time until 25% first twitch and 0.9 train-of-four ratio recoveries) in Caucasian [47.1 (6.4) and 77.5 (9.1) min)] compared with Chinese patients [(45.9 (4.7) and 72.3 (9.1) min)], respectively. Cisatracurium dose-response relationship and time-course-of-action were not influenced by geographic location. Thus, cisatracurium would not require dose adjustments between patients living in the two geographic locations.

With the increased interest in internationalization, many western universities have been working to attract students from China and other Asian countries. Texas A&M University has had a collaborative Ph.D. program with Ocean University, Qingdao, China since 2008. Chinese students spend their first one or two years in Qingdao, then transfer to TAMU to complete their coursework and carry out research. The program has so far produced 6 PhDs and one MS degree, and another 14 students are registered through the program. We anticipate sending U.S. students to China on a reciprocal basis, although the lack of Chinese-speaking U.S. students is an issue. Additionally, the Memorandum of Understanding has led to joint research projects between the two universities, with publications in top journals. Novel aspects of the program include joint funding by the U.S. and China, co-chairing graduate committees by both university faculties, interviewing students in Qingdao before they are accepted by TAMU, and initial studies in one country and then transfer to the other. Such programs require 'heroes' on each side to set up and continue the program who trust each other, as well as support from the upper administration. Even with such support, outside influences and different cultures can affect the effectiveness of the program.

To report 12 cases of pregnancy-associated fulminant type 1 diabetes mellitus (PF) found in China from 2003 to 2010. The clinical and biochemical characteristics of these cases with PF were compared with a group of cases of child-bearing age with fulminant type 1 diabetes that was not associated with pregnancy (NPF). The clinical and biochemical characteristics of 12 PF cases were analyzed retrospectively and then compared with those characteristics of 20 NPF cases in China. The difference between Chinese and Japanese PF cases was investigated. The mean values of the characteristics from PF and NPF cases in China, including postprandial serum C-peptide concentration, plasma glucose concentration, and serum chloride were different. Compared to the 22 PF cases in Japan, the mean age of these 12 PF cases was much younger. The mean fasting and postprandial serum C-peptide concentration level were lower, and the mean HbA1c levels was higher in 12 PF cases in China. Eight of 12 PF cases in China developed the disease during pregnancy. Other four PF case developed the disease within 2 weeks after delivery. 12 PF cases in China showed more severe beta-cell destruction, the prognosis of their fetuses was extremely poor.

Spatial and temporal variation of emission inventories for historical anthropogenic NMVOCs in China

Bo, Y.; Cai, H.; Xie, S. D.

2008-06-01

Multiyear emission inventories of anthropogenic NMVOCs in China for 1980-2005 were compiled based on time-varying statistical data, literature surveyed and model calculated emission factors, and were gridded at a high spatial resolution of 40 km×40 km using the GIS methodology. Chinese NMVOCs emissions had increased by 4.3 times at an annual average rate of 10.7% from 3.92 Tg in 1980 to 16.5 Tg in 2005. Vehicles, biomass burning, industrial processes, fossil fuel combustion, solvent utilization, and storage and transport generated 5.49 Tg, 3.91 Tg, 2.76 Tg, 1.98 Tg, 1.87 Tg, and 0.55 Tg of NMVOCs, respectively. Motorcycles, biofuel burning, heavy-duty vehicles, synthetic fibre production, biomass open burning, and industrial and commercial consumption were primary emission sources. Besides, from 1980 to 2005, vehicle emission increased notably from 6% to 33%, along with a slight increase for fossil fuel combustion from 9% to 12% and for industrial processes from 11% to 17%. Meanwhile, biomass burning emission decreased from 41% to 23%, along with the decrease of storage and transport and solvent utilization from 9% to 3% and from 28% to 11%, respectively. Varieties of NMVOCs emissions coincided well with China's economic growth. Conversions in economic structure and adjustment of fuel consumption structure in China during the period were the reasons for conspicuous variation of source contributions. The developed eastern and coastal regions produced more emissions than the relatively underdeveloped western and inland regions. Particularly, southeastern, northern, and central China covering 35% of China's territory, generated 59% of the total emissions, while the populous capital cities covering merely 4.5% of China's territory, accounted for 25% of the national emissions. Moreover, rural areas also experienced emission growth during the past two and a half decades, the reason of which was transfer of emission-intensive plants from city to county, inefficient fuel utilization, and biomass burning.

The characteristics of patients with acute ischaemic stroke (AIS) and their management vary across regions, which may influence outcomes. We examined for differential patterns of outcome between China and non-China participants of the ENhanced Control of Hypertension And Thrombolysis strokE stuDy (ENCHANTED), which tested different alteplase doses in AIS. ENCHANTED was an international, multicentre, open, blinded-endpoint trial of the effects of low-dose (0.6 mg/kg) versus standard-dose (0.9 mg/kg) intravenous alteplase on 90-day disability outcomes and symptomatic intracerebral haemorrhage (sICH) in 3310 patients with AIS. Participants (n=1419, 48%) in China were younger, and more often male, hypertensive and with prior stroke and coronary artery disease, but less likely to have atrial fibrillation and use antihypertensive, antithrombotic and lipid-lowering agents, compared with non-China patients with AIS. Although China participants had more AIS due to large artery occlusion, were treated later and had differing ancillary management, there was no significant difference in 90-day modified Rankin scale scores 2-6 (55.6% vs 47.8%; OR, adjusted for baseline and management factors 0.87 (95% CI 0.71 to 1.07; p=0.20)) and risk of sICH (Safe Implementation of Thrombolysis in Stroke-Monitoring Study criteria: 1.4% vs 1.8%; p=0.12) compared with non-China participants. There was no heterogeneity in the treatment effects of low-dose versus standard-dose alteplase between China and non-China participants. Patients with AIS recruited to the ENCHANTED trial in China had similar outcomes in response to thrombolysis treatment despite significantly differing demographic, clinical and management factors to patients with AIS in other regions.

Burden of non-communicable diseases (NCDs) is increasing rapidly in most of the developing countries including China, even in rural areas. Dearth of representative data called for an investigation to estimate the burden and identify the correlates of NCDs in rural China. A cross-sectional study was conducted involving a representative sample of 6003 consenting randomly selected rural residents aged 15 years or more, from 36 villages of Shijiazhuang in Hebei province of China between July 2010 and June 2011. Information on demographics and behavior were collected, body mass index (BMI) and blood pressure were measured and blood samples were tested to diagnose diabetes and hyperlipidemia. Majority participants were aged < 30 year, married and educated up to junior/senior high school level. Mean age for the 6003 participants was 37.4 ± 14.8. About 55.7% had BMI of 18.6-24.9. In past 12 months: 19.8% smoked daily, 41.6% were exposed to passive smoking, 28.5% drank alcohol, 10.4% skipped breakfasts frequently, 82.8% did never exercise and 25.3% had psychological disturbances. 51.1% were hypertensive, 6.7% were diabetic and 9.2% had hyperlipidemia. Based on self-reports, cardiovascular diseases (4.5%), cerebrovascular diseases (2.3%), cancers (0.2%), chronic obstructive pulmonary diseases (2%), orthopedic problems (12.1%) and gastrointestinal NCDs (7.8%) were identified among the participants, while proportion of subjects with one, two and three or more NCDs were 43%, 14.4% and 5.5% respectively. Higher odds of having more NCDs were associated with higher BMI (Kg/M(2)), family history of NCDs, daily and past history of smoking and drinking, passive smoking, lack of exercise, skipping breakfast and psychological disturbances. Despite limitations associated with cross-sectional design and self-reporting, observation in this large sample of rural residents could develop important insights regarding high burden of NCDs in this population. Based on the identified correlates, targeted intervention strategies seem to be required urgently to control NCDs in rural China.

Self-administered questionnaires were used to investigate mental health, including effort-reward imbalance questionnaire, Minnesota Satisfaction Questionnaire, Center for Epidemiological Survey-Depression Scale, and Psychological Capital Questionnaire. Results: Of all teachers, 58.9% had depressive symptoms. Depressive symptoms in university teachers were negatively correlated with the scores of psychological capital, supervisory commitment, and perceived organizational support ( r =-0.461, -0.306, and -0.366, all P <0.01) and were positively correlated with the score of occupational stress ( r =0.414, P <0.01) . Job satisfaction was positively correlated with psychological capital, perceived organizational support, and supervisory commitment ( r =0.650, 0.715, and 0.636, all P <0.01) and negatively correlated with occupational stress ( r =-0.475, P <0.01) . The direct effects of occupational stress, perceived organizational support, and supervisory commitment on job satisfaction were -0.30, 0.26, and 0.14, respectively, and their indirect effects were -0.0176, 0.0656, and 0.0368, respectively. The direct effects of occupational stress, perceived organizational support, and supervisory commitment on depressive symptoms were 0.20, -0.08, and -0.05, respectively, and their indirect effects was 0.033, -0.123, and -0.069, respectively. Conclusion: Occupational mental health is closely associated with job satisfaction in university teachers in Shenyang, and psychological capital has a mediating effect on perceived organizational support, supervisory commitment, occupational stress, job satisfaction, and depressive symptoms.

Objective: To examine the burden of disease(BOD)attributable to high-sodium diets in China in 2013. Methods: Data were extracted from the 2013 Global Burden of Disease Study for China to examine the BOD attributable to high-sodium diets in 2013, gender, and disease composition. Measurements for attributable BOD were population attributable fraction(PAF), deaths, standardized mortality and disability-adjusted life years(DALY)(not including Taiwan, China). An average world population age-structure for the period 2000-2025 was adopted to calculate age-standardized rates. Results: In 2013, deaths attributable to high-sodium diets accounted for 12.6% of all deaths and 14.5% of chronic disease deaths. Overall, 7.8% of deaths because of neoplasms, 25.2% of cardiovascular disease deaths, and 22.9% of chronic kidney disease deaths were attributable to high-sodium diets. A total of 1 176 553 deaths were attributable to high-sodium diets and the standardized mortality was 91.5/100 000, which was higher in men than in women(121.7/100 000 and 63.0/100 000, respectively). Overall, 22.759 million DALYs were attributable to high-sodium diets. The DALY standardized rate was 1 588.0/100 000, which was higher in men than in women(2 189.7/100 000 and 993.2/100 000, respectively). When compared by province, PAF in Xinjiang(25.0%), Qinghai(23.7%), Shanxi(23.2%), Tibet(22.1%)and Shandong(20.5%)was higher than other provinces. The standardized mortality in Xinjiang(239.4/100 000), Qinghai(238.9/100 000), Tibet(221.7/100 000), Shanxi(166.2/100 000)and Hebei(149.9/100 000)were higher than other provinces. The DALY standardized rate attributable to high-sodium diets was highest in Xinjiang(4 430.8/100 000), Qinghai(4 422.5/100 000), Tibet(4 021.4/100 000), Shanxi(2 816.6/100 000), and Hebei(2 624.9/100 000). Conclusion: The BOD attributable to high-sodium diets is a serious issue in China, particularly in men and in the northern provinces. Effective measures should be taken in northern provinces to reduce sodium intake.

The epidemiological characteristics of transient ischemic attacks (TIAs) in China are unclear. In 2013, we conducted a nationally representative, door-to-door epidemiological survey on TIA in China using a complex, multistage, probability sampling design. Results showed that the weighted prevalence of TIA in China was 103.3 [95% confidence interval (CI): 83.9–127.2] per 100,000 in the population, 92.4 (75.0–113.8) per 100,000 among men, and 114.7 (87.2–151.0) per 100,000 among women. The weighted incidence of TIA was 23.9 (17.8–32.0) per 100,000 in the population, 21.3 (14.3–31.5) per 100,000 among men, and 26.6 (17.0–41.7) per 100,000 among women. No difference in average prognosis was found between TIA and stroke in the population. Weighted risk of stroke among TIA patients was 9.7% (6.5–14.3%), 11.1% (7.5–16.1%), and 12.3% (8.4–17.7%) at 2, 30, and 90 days, respectively. The risk of stroke was higher among male patients with a history of TIA than among female patients with a history of TIA (OR: 2.469; 95% CI: 1.172–5.201; P = 0.018), and higher among TIA patients with hypertension than among TIA patients without hypertension (OR: 2.671; 1.547–4.613; P < 0.001). It can be concluded that there are an estimated 1.35 million TIA patients nationwide, with 0.31 million new cases of TIA annually in China. TIA patients were not better managed prior to a stroke event. Early risk of stroke among TIA patients is high. Sex and hypertension may be stroke-associated prognostic factors among TIA patients. TIA clinics and surveillance should be integrated into the national health-care system. PMID:28713329

Depression is one of the most common mental disorders among elderly subjects. The purpose of this study is to estimate the prevalence of depressive symptoms and the association between soybeans consumption and depressive symptoms among older residents in rural Northeast China. Cross-sectional study. A representative sample of the rural Northeast residents. This survey was conducted from July 2012 to August 2013 which randomly selected and examined a total of 1717 residents aged ≥ 65 years from the rural Northeast China. All participants completed the Patient Health Questionnaire-9 (PHQ-9). Information on demographic and lifestyle characteristics and blood biochemical indexes were collected by well-trained personnel. The prevalence of depressive symptoms in the elderly was 8.9%. Women had significantly higher prevalence of depressive symptoms than men (13.3% vs.4.6%, P<0.001). Individuals consuming soybeans ≥4times/week had statically lower possibility to have depressive symptoms than those rarely consuming (3.6%vs. 12.5%, P<0.05). In addition to some conventional risk factors like sex, annual income, educational status, current smoking and chronic diseases status were associated with depressive symptoms, proper sleep duration (7-8h/d) [OR(95%CI):0.28(0.15,0.53)] and frequently consumption of soybeans or soybean products [OR (95%CI): 0.36 (0.15,0.87) for 2-3times/week and OR (95%CI):0.50 (0.34,0.74) for ≥4times/week] significantly decreased the risk of depressive symptoms among elderly in rural Northeast China. Women had significantly higher prevalence of depressive symptoms than men in rural China. Individuals who rarely consume soybeans or soybean products are more likely to suffer depressive symptoms. Rural elderly residents should be cautiously screened to prevent or treat depression.

Multiferroic materials, showing the coexistence and coupling of ferroelectric and magnetic orders, are of great technological and fundamental importance. However, the limitation of single phase multiferroics with robust magnetization and polarization hinders the magnetoelectric effect from being applied practically. Magnetic frustration, which can induce ferroelectricity, gives rise to multiferroic behavior. In this paper, we attempt to construct an artificial magnetically frustrated structure comprised of manganites to induce ferroelectricity. A disordered stacking of manganites is expected to result in frustration at interfaces. We report here that a tri-color multilayer structure comprised of non-ferroelectric La0.9Ca0.1MnO3(A)/Pr0.85Ca0.15MnO3(B)/Pr0.85Sr0.15MnO3(C) layers with the disordered arrangement of ABC-ACB-CAB-CBA-BAC-BCA is prepared to form magnetoelectric multiferroics. The multilayer film exhibits evidence of ferroelectricity at room temperature, thus presenting a candidate for multiferroics.

To estimate the incidence of Type 2 diabetes mellitus (T2DM) and the number of those with T2DM attributable to overweight and obesity in China. We conducted a prospective cohort study among 15680 participants (46.4%, men) aged 35-74 years. The mean duration of follow-up was 8.0 years. We examined the relationship between overweight, obesity and risk of T2DM by Cox proportional hazards models. Population attributable risk (PAR) of overweight and obesity was also calculated. Moreover, we estimated the number of T2DM events attributed to overweight and obesity using PAR, incidence of T2DM and the population size of China in 2010. During a mean follow-up of 8.0 years, the age-standardized incidence of T2DM was 9.5 per 1000 person-years in men and 9.2 in women. Overweight accounted for 28.3% (95% confidence interval [CI]: 20.1, 36.2) of incident T2DM among men and 31.3% (95% CI: 25.5, 36.9) among women. The corresponding PAR of obesity was 10.1% (95% CI: 6.0, 14.2) among men and 16.8% (95% CI: 12.0, 21.6) among women. Approximately 3.32 million (95% CI: 2.47, 4.24) incident T2DM were attributable to overweight and obesity in Chinese adults who were 35 to 74 years in 2010. Our results indicate that incident T2DM is mainly attributable to overweight and obesity in China. It is extremely important to advocate healthy lifestyle and prevent excessive weight gain for reducing T2DM burden in China. Copyright © 2015. Published by Elsevier Ireland Ltd.

Syndemics of syphilis, HCV infection, and methamphetamine use along the east coast of China

PubMed Central

2014-01-01

Background An upsurge in club drug use has been observed in recent years in some cities of China, especially methamphetamine, which is quickly replacing heroin to become the most widespread drug across the nation. This study investigated the type of drugs used, syphilis and hepatitis C virus (HCV) infection and the correlates for syphilis, HCV and unprotected commercial sex behavior among drug users in two cities along the east coast of China. Methods A cross-sectional survey conducted in 2010 provided demographics, sexual and drug use behaviors, HIV knowledge and the utilization of intervention services among drug users. Blood samples were tested for HIV, syphilis, and HCV infection. Results Of 805 eligible participants, 0.2% were infected with HIV, 3.7% with HCV, and 9.6% with syphilis. Of the participants, 96.6% were methamphetamine users, 11.9% reported ever having used ≥2 types of these drugs, and 11.4% reported ever injecting drugs. In the multivariable logistic regression analysis, participants infected with syphilis were more likely to be female (adjusted odds ratio (AOR)=2.8, 95% confidence interval (CI): 1.2-6.5), have ever had commercial sex in the past 12 months (AOR=2.0, 95% CI: 1.0-3.9), be infected with HCV (AOR=12.1, 95% CI: 4.1-20.3) and less likely to have ever had sex with regular partners in the past 12 months (AOR=0.2, 95% CI: 0.1-0.6). Participants infected with HCV were more likely to have ever injected drugs (AOR=2.7, 95% CI: 1.1-6.5) and be infected with syphilis (AOR=8.0, 95% CI: 3.5-18.0). Participants who had unprotected sex with commercial sex partners in the last sexual encounter were more likely to be female (AOR=2.9, 95% CI:1.7-4.9), have middle school or lower level education (AOR=3.4, 95% CI:2.0-5.5), never have received intervention in the last year (AOR=2.1, 95%CI:1.2-3.6) and be infected with syphilis (AOR=4.2, 95% CI:2.4-7.4). Conclusions Methamphetamine is the predominant drug used among the drug users, the prevalence of syphilis and HCV infection are alarmingly high, and unprotected commercial sex was common among this group. The findings highlight the need for effective, multifaceted interventions addressing sexual and drug use-related risky behaviors among this group. Further research is needed to better understand the causal pathway of the syndemics. PMID:24533587

The earthworm, which has stasis removal and wound-healing functions, is a widely used Chinese herbal medicine in China. Schwann cell migration is critical for the regeneration of injured nerves. Schwann cells provide an essentially supportive activity for neuron regeneration. However, the molecular migration mechanisms induced by earthworms in Schwann cells remain unclear. Here, we investigate the roles of MAPK (ERK1/2, JNK and p38) pathways for earthworm-induced matrix-degrading proteolytic enzyme (PAs and MMP2/9) production in Schwann cells. Moreover, earthworm induced phosphorylation of ERK1/2 and p38, but not JNK, activate the downstream signaling expression of PAs and MMPs in a time-dependent manner. Earthworm-stimulated ERK1/2 and p38 phosphorylation was attenuated by pretreatment with U0126 and SB203580, resulting in migration and uPA-related signal pathway inhibition. The results were confirmed using small interfering ERK1/2 and p38 RNA. These results demonstrated that earthworms can stimulate Schwann cell migration and up-regulate PAs and MMP2/9 expression mediated through the MAPK pathways, ERK1/2 and p38. Taken together, our data suggests the MAPKs (ERK1/2, p38)-, PAs (uPA, tPA)-, MMP (MMP2, MMP9) signaling pathway of Schwann cells regulated by earthworms might play a major role in Schwann cell migration and nerve regeneration.

Objective: To analyze the rate of prevalence, awareness, treatment and control of hypertension among women at reproductive age (18-49 years old) in China in 2013. Methods: The analysis used data obtained from the China Chronic and non-communicable disease surveillance in 2013.The surveillance included 176 534 adults aging ≥18 years old, who were selected from 302 surveillance points by multi-stage cluster random sampling method. A total of 46 674 women at reproductive age (18-49 years old) were investigated. Blood pressures were measured by electronic blood pressure monitor. After being weighted according to complex sampling scheme and post-stratification, the rate of prevalence, awareness, treatment and control of hypertension were compared by different characteristics such as age, education, urban and rural areas, and geographic locations. Results: The prevalence of hypertension among women at reproductive age (18-49 years old) in China in 2013 was 13.5%. The rate in the rural areas was higher than that in urban areas (χ(2)=46.23, P< 0.05), which were 14.5% and 12.3%, respectively. The prevalence in eastern, central and western geographic locations were separately 13.9%, 13.2% and 13.1%, there was no statistical difference (χ(2)=0.56, P> 0.05). The hypertension prevalence in all age groups (18-24, 25-29, 30-34, 35-39, 40-44, 45-49 years old) were 6.6%, 9.2%, 9.6%, 12.0%, 17.9% and 28.3%, respectively. The prevalence of hypertension showed a rising trend with age increasing ( t= 12.32, P< 0.05). The awareness, treatment and control rates of hypertension were separately 25.8%, 22.7% and 7.4% in women at reproductive age (18-49 years old), which were 31.6%, 28.2% and 9.4%, respectively in urban areas; and 21.3%, 18.5% and 5.9%, respectively in rural areas. The rates in urban areas were all higher than those in rural areas (chi square were separately 18.98, 21.31, and 6.80, P values <0.05). The treatment rate of hypertension was 86.8% among who had been aware of hypertension, and the treatment rate of hypertension was 31.8% among who received control of hypertension. The treatment rate among who had been aware of hypertension in eastern, central and western locations were 89.3%, 88.3% and 79.5%, respectively. The control rates in eastern, central and western locations were 8.5%, 8.1% and 4.7%, respectively. The treatment rate among who had been aware of hypertension and control rate in the eastern and central geographic locations was higher than that in western locations (chi square were separately 10.05 and 7.25, P values <0.05). Conclusion: The prevalence of hypertension in women at reproductive age (18-49 years old) was comparatively high, and the rates of awareness, treatment and control were low. The differences showed statistical significance between urban and rural areas.

Phytosterols are well-known for their cholesterol-lowering effects, and the structures and forms of phytosterols affect their bioactivity. We aimed to illustrate the phytosterol profiles in common foods and estimate their natural intake in five geographical regions and among different age groups in China. In total, 12 phytosterols in free and esterified forms of 119 foods from five regions across China were examined using gas chromatography-mass spectrometry. Then, the dietary intake of phytosterols was calculated combined with the dietary foods intake data of Chinese people. The total phytosterol content was highest in vegetable oils (150.4-1230.9 mg/100 g), followed by legumes (129.6-275.6 mg/100 g), nuts (18.9-255.2 mg/100 g), and cereals (11.9-93.8 mg/100 g). Vegetables and fruits contained lower contents of total phytosterols. Phytosterols were mainly esterified in most common foods except in nuts. The predominant phytosterols were β-sitosterol, campesterol, and stigmasterol, all of which belonged to plant sterols and 4-desmethylsterols. Total phytosterol intake varied across different regions, ranging between 257.7 and 473.7 mg/standard-person (sp)/day, with the highest intake in Beijing, followed by Hangzhou, Wuhan, Chongqing, and Guangzhou. However, phytosterol proportion was similar across regions, with β-sitosterol accounting for 46.5-50.3% of the natural intake. Phytosterol intake was mainly constituted by plant sterols and 4-desmethylsterols in esterified form (61.9-74.6%). At the age of 2-70 years, phytosterol intake ranged from 154.3 mg/day to 348.0 mg/day in the national scale.
