1Prevalence of Atrial Fibrillation in China and Its Risk Factors显示文摘Objective To study the prevalence of atrial fibrillation(AF)and the relation with its risk factors in China.Methods A total of 19 363 participants(8635 males and 10 728 females) aged ≥35 years in geographically dispersed urban and rural regions of China were included in this cross-sectional survey.All participants received questionnaire,physical and blood examination.Echocardiography were performed for AF patients found in the survey.Results Of the 19 363 participants,199 were diagnosed with AF.The estimated age-standardized prevalence of AF was 0.78% in men and 0.76% in women.The prevalence of AF in participants aged <60 years was 0.41% in men and 0.43% in women,and was 1.83% in both men and women aged ≥60 years.About 19.0% of males and 30.9% of females with AF were diagnosed with valve disease.Age-and sex-adjusted multivariable logistic regression analysis revealed that myocardial infarction,left ventricular hypertrophy(LVH),obesity,and alcohol consumption were associated with a increased risk of AF(P<0.05).Conclusion The age standardized prevalence of AF is 0.77% in the participants enrolled in the present study.The number of AF cases aged ≥35 years is 5.26 million according to 2010 Chinese Census.Most risk factors for AF,identified mainly in Western countries,are also detected in China.LI Ying WU Yang Feng CHEN Ke Ping LI Xian ZHANG Xing XIE Gao Qiang WANG Fang Zheng ZHANG Shu 2013Biomedical and Environmental Sciences2013,26,9:48
2A scientometric review of biochar research in the past 20 years(1998-2018)显示文摘Biochar is the carbon-rich product obtained from the thermochemical conversion of biomass under oxygen-limited conditions.Biochar has attained extensive attention due to its agronomical and environmental benefits in agro-ecosystems.This work adopts the scientometric analysis method to assess the development trends of biochar research based on the literature data retrieved from the Web of Science over the period of 1998-2018.By analysing the basic characteristics of 6934 publications,we found that the number of publications grew rapidly since 2010.Based on a keyword analysis,it is concluded that scholars have had a fundamental recognition of biochar and preliminarily found that biochar application had agronomic and environmental benefits during the period of 1998-2010.The clustering results of keywords in documents published during 2011-2015 showed that the main research hotspots were“biochar production”,“biochar and global climate change”,“soil quality and plant growth”,“organic pollutants removal”,and“heavy metals immobilization”.While in 2016-2018,beside these five main research hotspots,“biochar and composting”topic had also received greater attention,indicating that biochar utilization in organic solid waste composting is the current research hotspot.Moreover,updated reactors(e.g.,microwave reactor,fixed-bed reactor,screw-feeding reactor,bubbling fluidized bed reactor,etc.)or technologies(e.g.,solar pyrolysis,Thermo-Catalytic Reforming process,liquefaction technology,etc.)applied for efficient energy production and modified biochar for environmental remediation have been extensively studied recently.The findings may help the new researchers to seize the research frontier in the biochar field.Ping Wu Syed Tahir Ata-Ul-Karim Bhupinder Pal Singh Hailong Wang Tongliang Wu Cun Liu Guodong Fang Dongmei Zhou Yujun Wang Wenfu Chen 2019Biochar2019,1,1:36
3Loess in the Tian Shan and its implications for the development of the Gurbantunggut Desert and drying of northern Xinjiang显示文摘Eolian loess is widely distributed on the various geomorphic surfaces between 700-2400 m a.s.l. on the northern slope of the Tian Shan. It is formed in a synchronous manner with dust transported from the Gurbantunggut Desert in the Junggar Basin. The thickest section of loess was found in the Shawan and Shihezi regions. Paleomagnetic and climatic proxy analyses of over 71 m of a loess-paleosol sequence on the highest terrace of the Qingshui He (River) in the Shawan show that the paleomagnetic Bruhues/Matuy-ama (B/M) boundary lies at the bottom of paleosol S8, at a depth of 69.5 m, and the bottom of the sequence was estimated to be -0.8 Ma. This implies that the extremely dry climatic conditions in the Junggar Basin and the initial Gurbantunggut Desert were present at least by 0.8 Ma. High-resolution grain size series demonstrate that this area and desert expansion experienced two dramatic periods of desert expansions that occurred at -0.65 Ma and 0.5 Ma, respectively; and the subsequent continuousFANG Xiaomin SHI Zhentao YANG Shengli YAN Maodu LI Jijun JIANG Ping’an 2002Chinese Science Bulletin2002,47,16:33
4ShRNA-mediated gene silencing of β-catenin inhibits growth of human colon cancer cells显示文摘AIM: To observe the gene silencing mediated by the specific shRNA targeted against β-catenin and its effect on cell proliferation and cycle distribution in the human colon cancer cell line Colo205. METHODS: Two shRNA plasmid vectors against β-catenin were constructed and transfected into Colo205 cells with LipofectamineTM2000. The down-regulations of β-catenin, c-myc and cyclinD1 expressions were detected by RT-PCR and western blot analysis. The cell proliferation inhibitions were determined by MTT assay and soft agar colony formation assay. The effect of these two β-catenin shRNAs on cell cycle distribution and apoptosis was examined by flow cytometry. RESULTS: These two shRNA vectors targeted against β-catenin efficiently suppressed the expression of β-catenin and its down stream genes, c-myc and cyclinD1. The expression inhibition rates were around 40%-50% either at the mRNA or at the protein level. The shRNA-mediated gene silencing of β-catenin resulted in significant inhibition of cell growth both on the culture plates and in the soft agar. Moreover, the cancer cells showed significant G0/G1 arrest and increased apoptosis at 72 h post transfection due to gene silencing. CONCLUSION: These specific shRNAs targeted against β-catenin could have a gene silencing effect and block the WNT signaling pathway. They could inhibit cell growth, increase apoptosis, and induce cell cycle arrest in Colo205 cells. ShRNA interference against β-catenin is of potential value in gene therapy of colon cancer.Wen-Sheng Huang Jian-Ping Wang Ting Wang Jie-Yu Fang Ping Lan Jin-Ping Ma 2007World Journal of Gastroenterology2007,13,48:33
5Efficacy and safety of Xinfeng capsule in patients with rheumatoid arthritis:a multi-center parallel-group double-blind randomized controlled trial显示文摘OBJECTIVE:To evaluate the efficacy and safety of Xinfeng capsule in patients suffering rheumatoid arthritis(RA).METHODS:A multi-center parallel-group designed,double-blind,randomized,controlled trial was conducted.Totally 304 RA patients were assigned to two groups:one group was administered Xinfeng capsule(XFC) plus the placebo of leflunomide and the other given leflunomide(LEF) plus the placebo of XFC for twelve weeks.The clinical and laboratory parameters were compared at baseline and fourth,eighth,and twelfth weeks.RESULTS:After twelve-week treatment,patients in two groups all showed some trend of effectiveness when compared in terms of American Rheumatism Association(ACR) recommended 20%,50%,70%improvement criteria,but it was insignificant.The validity in ameliorate modified disease activity score(DAS28) and laboratory indexes as erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),rheumatoid factor(RF) were also found no difference.The score of health assessment questionnaire(HAQ),self-rating anxiety scale(SAS),self-rating depression scale(SDS) and quality of life questionnaire with rheumatoid arthritis(RAQOL)both lower than the first week and the changes showed no difference.However,the score of SDS dropped more in XFC group than in the other.A total of 147 adverse reaction cases were reported,which shows no difference between the two groups.The most common adverse reactions were hepatic impairment,anemia,leukocytopenia,epigastric discomfort and phalacrosis.CONCLUSION:XFC demonstrated better improvement in the scores of SDS and compared with those of LEF group.Liu Jian Wang Yuan Huang Chuanbing Xu Jianhua Li Zhijun Xu Liang He Liyun Sun Yue Wang Yali Xu Shengqian Zhao Ping Mao Tongjun Tan Bin Zhu Fubing Zhang Pingheng Fang Li 2015Journal of Traditional Chinese Medicine2015,35,5:27
6Fast-track rehabilitation vs conventional care in laparoscopic colorectal resection for colorectal malignancy: A meta-analysis显示文摘AIM:To evaluate the fast-track rehabilitation protocol and laparoscopic surgery(LFT)vs conventional care strategies and laparoscopic surgery(LCC).METHODS:Studies and relevant literature comparing the effects of LFT and LCC for colorectal malignancy were identified in MEDLINE,the Cochrane Central Register of Controlled Trials and EMBASE.The complications and re-admission after approximately 1 mo were assessed.RESULTS:Six recent randomized controlled trials(RCTs)were included in this meta-analysis,which related to 655 enrolled patients.These studies demonstrated that compared with LCC,LFT has fewer complications and a similar incidence of re-admission after approximately 1 mo.LFT had a pooled RR of 0.60(95%CI:0.46-0.79,P<0.001)compared with a pooled RR of 0.69(95%CI:0.34-1.40,P>0.5)for LCC.CONCLUSION:LFT for colorectal malignancy is safe and efficacious.Larger prospective RCTs should be conducted to further compare the efficacy and safety of this approach.Ping Li Fang Fang Jia-Xun Cai Dong Tang Qing-Guo Li Dao-Rong Wang 2013World Journal of Gastroenterology2013,19,47:26
7Antisense telomerase RNA induced human gastric cancer cell apoptosis显示文摘INTRODUCTION Human tissue homeostasis is precisely regulated bycellular division,differentiation and death.Normalhuman somatic cells progressively lose telomererestriction fragment(TRF)length with eachsuccessive cell division,eventually leading tocellular quiescence,chromosomal end-degradationand apoptosis.On the contrary,stabilization oftelomere lengths by expressing telomerase,an RNA-dependent DNA polymerase,may be involved incellular immortality and carcinogenesis.Fang Xin Zhang Xue Yong Zhang Dai Ming Fan Zi Yun Deng Yan Yan Han Ping Wu Jun Jie Fan 2000World Journal of Gastroenterology2000,6,3:24

9Charlson comorbidity index helps predict the risk of mortality for patients with type 2 diabetic nephropathy显示文摘研究目的:探讨Charlson合并症指数(CCI)对2型糖尿病肾病死亡率的预测作用。研究方法:建立2型糖尿病肾病研究队列,根据CCI评分将患者合并症的严重程度分为三度:轻度(CCI1–2分)、中度(CCI 3–4分)、重度(CCI≥5分)。将影响死亡率的因素及按CCI分层后的组间差异指标进行Logistic回归分析及方差分析(ANOVA)。Kaplan-Meier生存曲线分析CCI指数对生存时间及死亡率的影响。重要结论:533例2型糖尿病肾病患者纳入研究。所有患者的CCI评分均大于1,44.7%(238/533)的患者死亡。患者的死亡率随CCI评分增加而增加,CCI 1–2分患者的死亡率为21.0%(50/238),CCI 3–4分患者的死亡率为56.7%(135/238),CCI≥5分患者的死亡率为22.3%(53/238)。Logistic回归分析显示CCI评分、血红蛋白和血浆白蛋白水平是患者死亡率的预测因子(P<0.05)。方差分析结果显示,与CCI评分相对较低的患者相比,CCI评分越高的患者其血红蛋白水平较低,而血清肌酐较高,死亡率也更高。Kaplan-Meier生存曲线显示CCI评分越高的患者生存时间越短。CCI评分是一种简单易行且实用的评估疾病合并症的方法,可用于预测2型糖尿病肾病患者的死亡率。关注2型糖尿病肾病患者的合并症将有利于早期、有效治疗及改善预后。You-qun HUANG Rong GOU Yong-shu DIAO Qing-hua YIN Wen-xing FAN Ya-ping LIANG Yi CHEN Min WU Li ZANG Ling LI Jing ZANG Lu CHENG Ping FU Fang LIU 2014Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014,15,1:23
10Phosphorus recovery from biogas fermentation liquid by Ca-Mg loaded biochar显示文摘Shortage in phosphorus(P) resources and P wastewater pollution is considered as a serious problem worldwide. The application of modified biochar for P recovery from wastewater and reuse of recovered P as agricultural fertilizer is a preferred process. This work aims to develop a calcium and magnesium loaded biochar(Ca–Mg/biochar) application for P recovery from biogas fermentation liquid. The physico-chemical characterization, adsorption efficiency, adsorption selectivity, and postsorption availability of Ca-Mg/biochar were investigated. The synthesized Ca–Mg/biochar was rich in organic functional groups and in Ca O and Mg O nanoparticles. With the increase in synthesis temperature, the yield decreased, C content increased, H content decreased, N content remained the same basically, and BET surface area increased. The P adsorption of Ca–Mg/biochar could be accelerated by nano-Ca O and nano-Mg O particles and reached equilibrium after 360 min.The process was endothermic, spontaneous, and showed an increase in the disorder of the solid–liquid interface. Moreover, it could be fitted by the Freundlich model. The maximum P adsorption amounts were 294.22, 315.33, and 326.63 mg/g. The P adsorption selectivity of Ca–Mg/biochar could not be significantly influenced by the typical p H level of biogas fermentation liquid. The nano-Ca O and nano-Mg O particles of Ca–Mg/biochar could reduce the negative interaction effects of coexisting ions. The P releasing amounts of postsorption Ca–Mg/biochar were in the order of Ca–Mg/B600 > Ca–Mg/B450 > Ca–Mg/B300. Results revealed that postsorption Ca–Mg/biochar can continually release P and is more suitable for an acid environment.Ci Fang Tao Zhang Ping Li Rongfeng Jiang Shubiao Wu Haiyu Nie Yingcai Wang 2015Journal of Environmental Sciences2015,27,3:21
11Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration.Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen 2019National Science Review2019,6,4:21

These endocrine cells were scattered in gastrointestinal mucosa, intermuscular nerve plexus, gland body, pancreatic gland and islands under APUD system. CAL- and GH-IRE cells in the pancreatic islands of fishes showed functional diversity for these two hormones. Their morphological feature provides evidence of endocrine-paracrine and endocrine-exocrine acting mode. This research can morphologically prove that the GEP endocrine system of fish ( the lowest vertebrate) is almost the same as of mammal and human.Qian Sheng Pan Zhi Ping Fang Feng Jie Huang 2000World Journal of Gastroenterology2000,6,6:20

14Effect of domperidone therapy on nocturnal dyspeptic symptoms of functional dyspepsia patients显示文摘AIM:To investigate the incidence of nocturnal dyspeptic symptoms in patients with functional dyspepsia(FD) and whether prokinetic drugs can alleviate them. METHODS:Eighty-five consecutive Chinese patients with FD were included in this study.One week after single-blinded placebo run-in treatment,baseline nocturnal intragastric pH,bile reflux and nocturnal dyspeptic symptoms of eligible patients,including epigastric pain or discomfort,abdominal distention and belching, were investigated with questionnaires.Patients exhibiting nocturnal dyspeptic symptoms were randomly and double-blindly assigned to domperidone group or placebo group.Nocturnal intragastric pH and percentage of duodenogastric bile reflux time were determined after treatment. RESULTS:Of the 85 FD patients,2 females withoutnocturnal symptoms,who responded to placebo run-in treatment,were excluded from the study,30(36.1%) exhibited nocturnal dyspeptic symptoms with increased duodenogastric bile reflux time(intragastric bilirubin absorbance>0.14)and mean gastric pH(confirming the existence of bile reflux)(P=0.021,0.023) at night were included in the study.Of these 30 patients,21(70%)had overt nocturnal duodenogastric bile reflux,which was significantly higher than that of those without nocturnal symptoms(P=0.026).The 30 patients were allocated to domperidone group or placebo group(n=15).The nocturnal duodenogastric bile reflux and gastric pH were significantly decreased after domperidone treatment(P=0.015,0.021).The severity score of nocturnal dyspeptic symptoms was also significantly decreased after domperidone treatment (P=0.010,0.015,0.026),which was positively correlated with the reduced nocturnal bile reflux or gastric pH(r=0.736,0.784,0.753 or r=0.679,0.715,0.697, P=0.039,0.036,0.037 or P=0.043,0.039,0.040). CONCLUSION:A subgroup of Chinese FD patients show overt nocturnal dyspeptic symptoms,which may be correlated with the excessive nocturnal duodenogastric bile reflux.Domperidone therapy can alleviate these symptoms.Chen, Sheng-Liang Ji, Jie-Ru Xu, Ping Cao, Zhi-Jun Mo, Jian-Zhong Fang, Jing-Yuan Xiao, Shu-Dong 2010World Journal of Gastroenterology2010,16,5:18
15The first year follow-up after colorectal adenoma polypectomyis important: A multiple-center study in symptomatichospital-based individuals in China显示文摘The recurrence of colorectal adenoma(CRA)is high.Although there are guidelines for colonoscopy surveillance after polypectomy in other countries,little is known about its recurrence rate and recurrence peak,especially in China.The aim of the present research is to investigate how long after polypectomy follow-up should take and to analyze risk factors of recurrence.1208 patients who received polypectomies fromfive clinical research centers in four regions of China(Shanghai,Guangzhou,Nanjing and Beijing)were included.They were divided into 4 groups:group A(follow-up≤1 year after poly-pectomy),group B(follow-up 2–3 years after polypect-omy),group C(follow-up 4–5 years after polypectomy),and group D(follow-up>5 years after polypectomy).The sex,age,adenoma location,size,number,and pathological characteristics were compared.On the whole,the recur-rence rate was 59.46%in group A,61.09%in group B,78.07%in group C,and 87.12%in group D,which indicated an increased tendency with a prolonged follow-up duration.There was a significant difference between group A and C or D,and between group B and C or D(P<0.01),but there was no statistical difference between group A and B.Additionally,the recurrent patients in thefirst year had a recurrence rate of 97.33%in thefirst three years(59.46/61.09),which means that the peak of recurrence was almost entirely concentrated in thefirst year.The recurrence rate was higher in males and the elder.The risk factors included multiple numbers,villous feature,high-grade dysplasia of medium or smaller size and location in the distal colon.In conclusion,the peak of recurrence was almost totally concentrated in thefirst year;meanwhile,thefirst year follow-up is of critical importance in China.It may not be necessary to do the follow-up examination during the second and third years,but after three years,another colonoscopy should be undertaken.Qin-Yan GAO Hui-Min CHEN Jian-Qiu SHENG Ping ZHENG Cheng-Gong YU Bo JIANG Jing-Yuan FANG 2010Frontiers of Medicine2010,4,4:17
16Effcts of Irrigation Patterns and Nitrogen Fertilization on Rice Yield and Microbial Community Structure in Paddy Soil显示文摘Water and nitrogen (N) are considered the most important factors affecting rice production and play vital roles in regulating soil microbial biomass, activity, and community. The effects of irrigation patterns and N fertilizer levels on the soil microbial community structure and yield of paddy rice were investigated in a pot experiment. The experiment was designed with four N levels of 0 (N0), 126 (N1), 157.5 (N2), and 210 kg N ha-1 (N3) under two irrigation patterns of continuous water-logging irrigation (WLI) and water-controlled irrigation (WCI). Phospholipid fatty acid (PLFA) analysis was conducted to track the dynamics of soil microbial communities at tillering, grain-filling, and maturity stages. The results showed that the maximums of grain yield, above-ground biomass, and total N uptake were all obtained in the N2 treatment under WCI. Similar variations in total PLFAs, as well as bacterial and fungal PLFAs, were found, with an increase from the tillering to the grain-filling stage and a decrease at the maturity stage except for actinomycetic PLFAs, which decreased continuously from the tillering to the maturity stage. A shift in composition of the microbial community at different stages of the plant growth was indicated by principal component analysis (PCA), in which the samples at the vegetative stage (tillering stage) were separated from those at the reproductive stage (grain-filling and maturity stages). Soil microbial biomass, measured as total PLFAs, was significantly higher under WCI than that under WLI mainly at the grain-filling stage, whereas the fungal PLFAs detected under WCI were significantly higher than those under WLI at the tillering, grain-filling, and maturity stages. The application of N fertilizer also significantly increased soil microbial biomass and the main microbial groups both under WLI and WCI conditions. The proper combination of irrigation management and N fertilizer level in this study was the N2 (157.5 kg N ha-1) treatment under the water-controlled irrigation pattern.LI Ya-Juan CHEN Xing I.H.SHAMSI FANG Ping LIN Xian-Yong 2012Pedosphere2012,22,5:17
17Epigastric pain syndrome: What can traditional Chinese medicine do? A randomized controlled trial of Biling Weitong Granules显示文摘BACKGROUND Recent research suggests that although prokinetic agents,acid suppressors,and radical treatment for Helicobacter pylori infection may be effective in patients with functional dyspepsia(FD),a large proportion of patients still fail to respond to these treatments or may suffer from severe adverse reactions.Many traditional Chinese medicinal herbs can regulate the status of the entire body and have special advantages in the treatment of functional diseases.The present study was designed to verify the efficacy of Biling Weitong Granules(BLWTG),a traditional Chinese medicinal herbal compound formula,in alleviating epigastric pain syndrome(EPS)in FD patients,in an attempt to provide an effective prescription for the clinical treatment of this disease.AIM To evaluate the clinical efficacy and safety of BLWTG in treating EPS in patients with FD.METHODS In this multicenter,stratified,randomized,double-blind,placebo-controlled,parallel group clinical trial,eligible patients were randomized into the BLWTG and placebo groups who were treated for 6 wk.Efficacy indicators including the severity and frequency of EPS and the time to pain resolution and safety indicators including adverse events were observed and compared.RESULTS The baseline demographic data and clinical characteristics,such as epigastric pain symptoms,pain intensity,and frequency of attacks,were matched between the two groups before randomization.After 6 wk of treatment and after the center effect was eliminated,the epigastric pain was significantly improved in 28.33%and 85.59%of the patients in the placebo and BLWTG groups,respectively(P<0.05).At 6 wk,the resolution rate of epigastric pain was 15%and 69.49%in the placebo and BLWTG groups,respectively(P<0.05).The differences of total FD clinical score between these two groups were significant(P<0.05)at 2,4,and 6 wk(P<0.05).The scores of each item and the total score in the Functional Digestive Disorders Quality of Life Questionnaire showed significant differences between the two groups at 6 wk after both the center and interaction effects were eliminated(P<0.05).There was no significant difference in the incidence of adverse events between the two groups,and no serious adverse event was noted during the observation.CONCLUSION Compared with placebo,BLWTG markedly improved EPS in FD patients without causing serious adverse reactions.Yan-Dong Wen Fang Lu Ying-Pan Zhao Ping Wang Qian Yang Jun-Xiang Li Hui-Zhen Li Li-Li Chi Zheng-Hua Zhou Yan-Ping Tang Jin-Kang Xu Yang Zhao Xu-Dong Tang 2020World Journal of Gastroenterology2020,26,28:16
18Report on Childhood Obesity in China (10): Association of Sleep Duration with Obesity显示文摘Objectives To explore the association of sleep duration with obesity among children in urban areas of China.Methods A total of 6 576 children(3 293 boys and 3 283 girls) aged 7-11 years were randomly selected from 36 primary schools in 6 metropolitan cities in China.A 7-day Physical Activity Recall was used to assess the sleep duration and physical activity level.The height,weight,waist circumference(WC) and percentage of body fat(%BF,as determined by bioelectrical impedance analysis technique) were measured by following the standardized operation procedures.The information on demography,lifestyle and eating habits was collected with a self-administered questionnaire from participants and their parents.Results The average sleep duration per night in the children was 9.7 h with the decreasing trends along with the increase of age(P<0.05).The sleep duration was negatively associated with body mass index(BMI) and WC in both boys and girls after adjustment for confounders(β value-0.23 and-0.82 for boys,-0.24 and-0.91 for girls,respectively,P<0.01).However,no significant association of sleep duration with %BF was found.Children who slept less than 9.0 h per night had a higher risk for overweight and obesity(OR=1.29,95% CI:1.01,1.64) and abdominal obesity(OR=1.38,95% CI:1.04,1.83) as compared with those who slept for 10.0-10.9 h.Conclusions Short sleep duration is associated with obesity.It is important to ensure adequate sleep duration of children and foster their healthy lifestyle at an early stage of life.MENG Li Ping LIUAi Ling HU Xiao Qi ZHANG Qian DU Song Ming FANG Hong Yun MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin MA Guan Sheng 2012Biomedical and Environmental Sciences2012,25,2:16
