1Entropy method for determination of weight of evaluating indicators in fuzzy synthetic evaluation for water quality assessment显示文摘Considering the difficulty of fuzzy synthetic evaluation method in calculation of the multiple factors and ignorance of the relationship among evaluating objects, a new weight evaluation process using entropy method was introduced. This improved method for determination of weight of the evaluating indicators was applied in water quality assessment of the Three Gorges reservoir area. The results showed that this method was favorable for fuzzy synthetic evaluation when there were more than one evaluating objects. One calculation was enough for calculating every monitoring point. Compared with the original evaluation method, the method predigested the fuzzy synthetic evaluation process greatly and the evaluation results are more reasonable.ZOU Zhi-hong YUN Yi SUN Jing-nan 2006Journal of Environmental Sciences2006,18,5:203

3Annual report on status of cancer in China,2010显示文摘Objective:Population-based cancer registration data in 2010 were collected,evaluated and analyzed by the National Central Cancer Registry(NCCR) of China.Cancer incident new cases and cancer deaths were estimated.Methods:There were 219 cancer registries submitted cancer incidence and death data in 2010.All data were checked and evaluated on basis of the criteria of data quality from NCCR.Total 145 registries' data were qualified and accepted for cancer statistics in 2010.Pooled data were stratified by urban/rural,area,sex,age group and cancer site.Cancer incident cases and deaths were estimated using age-specific rates and national population.The top ten common cancers in different groups,proportion and cumulative rate were also calculated.Chinese census in 2000 and Segi's population were used for age-standardized incidence/ mortality rates.Results:All 145 cancer registries(63 in urban and 82 in rural) covered a total of 158,403,248 population(92,433,739 in urban and 65,969,509 in rural areas).The estimates of new cancer incident cases and cancer deaths were 3,093,039 and 1,956,622 in 2010,respectively.The morphology verified cases(MV%) accounted for 67.11% and 2.99% of incident cases were identified through death certifications only(DCO%) with mortality to incidence ratio(M/I) of 0.61.The crude incidence rate was 235.23/100,000(268.65/100,000 in males,200.21/100,000 in females),age-standardized incidence rates by Chinese standard population(ASIRC,2000) and by world standard population(ASIRW) were 184.58/100,000 and 181.49/100,000 with the cumulative incidence rate(0-74 years old) of 21.11%.The cancer incidence and ASIRC were 256.41/100,000 and 187.53/100,000 in urban areas whereas in rural areas,they were 213.71/100,000 and 181.10/100,000,respectively.The crude cancer mortality in China was 148.81/100,000(186.37/100,000 in males and 109.42/100,000 in females),age-standardized incidence rates by Chinese standard population(ASMRC,2000) and by world standard population(ASMRW) were 113.92/100,000 and 112.86/100,000,and the cumulative incidence rate(0-74 years old) was 12.78%.The cancer mortality and ASMRC were 156.14/100,000 and 109.21/100,000 in urban areas,whereas in rural areas,they were 141.35/100,000 and 119.00/100,000 respectively.Lung cancer,gastric cancer,colorectal cancer,liver cancer,esophageal cancer,pancreas cancer,encephaloma,lymphoma,female breast cancer and cervical cancer,were the most common cancers,accounting for 75% of all cancer cases in urban and rural areas.Lung cancer,gastric cancer,liver cancer,esophageal cancer,colorectal cancer,pancreatic cancer,breast cancer,encephaloma,leukemia and lymphoma accounted for 80% of all cancer deaths.Conclusions:The coverage of cancer registration population had a rapid increase and could reflect cancer burden in each area and population.As the basis of cancer control program,cancer registry plays an irreplaceable role in cancer epidemic surveillance,evaluation of cancer control programs and making anticancer strategy.China is facing serious cancer burden and prevention and control should be enhanced.Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Hongmei Zeng Xiaonong Zou Jie He 2014Chinese Journal of Cancer Research2014,26,1:198
4Cancer incidence and mortality in China, 2014显示文摘Background: National Central Cancer Registry of China(NCCRC) updated nationwide cancer statistics using population-based cancer registry data in 2014 collected from all available cancer registries.Methods: In 2017, 449 cancer registries submitted cancer registry data in 2014, among which 339 registries' data met the criteria of quality control and were included in analysis. These cancer registries covered 288,243,347 population, accounting for about 21.07% of the national population in 2014. Numbers of nationwide new cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by area, sex, age group and cancer type. The world Segi's population was applied for agestandardized rates.Results: A total of 3,804,000 new cancer cases were diagnosed, the crude incidence rate was 278.07/100,000(301.67/100,000 in males, 253.29/100,000 in females) and the age-standardized incidence rate by world standard population(ASIRW) was 186.53/100,000. Calculated age-standardized incidence rate was higher in urban areas than in rural areas(191.6/100,000 vs. 179.2/100,000). South China had the highest cancer incidence rate while Southwest China had the lowest incidence rate. Cancer incidence rate was higher in female for population between20 to 54 years but was higher in male for population younger than 20 years or over 54 years. A total of 2,296,000 cancer deaths were reported, the crude mortality rate was 167.89/100,000(207.24/100,000 in males,126.54/100,000 in females) and the age-standardized mortality rate by world standard population(ASMRW) was106.09/100,000. Calculated age-standardized mortality rate was higher in rural areas than in urban areas(110.3/100,000 vs. 102.5/100,000). East China had the highest cancer mortality rate while North China had the lowest mortality rate. The mortality rate in male was higher than that in female. Common cancer types and major causes of cancer death differed between age group and sex.Conclusions: Heavy cancer burden and its disparities between area, sex and age group pose a major challenge to public health in China. Nationwide cancer registry plays a crucial role in cancer prevention and control.Wanqing Chen Kexin Sun Rongshou Zheng Hongmei Zeng Siwei Zhang Changfa Xia Zhixun Yang He Li Xiaonong Zou Jie He 2018Chinese Journal of Cancer Research2018,30,1:832
5Single-cell RNA-seq data analysis on the receptor ACE2 expression reveals the potential risk of different human organs vulnerable to 2019-nCoV infection显示文摘It has been known that,the novel coronavirus,2019-nCoV,which is considered similar to SARS-CoV,invades human cells via the receptor angiotensin converting enzyme II(ACE2).Moreover,lung cells that have ACE2 expression may be the main target cells during 2019-nCoV infection.However,some patients also exhibit non-respiratory symptoms,such as kidney failure,implying that 2019-nCoV could also invade other organs.To construct a risk map of different human organs,we analyzed the single-cell RNA sequencing(scRNA-seq)datasets derived from major human physiological systems,including the respiratory,cardiovascular,digestive,and urinary systems.Through scRNA-seq data analyses,we identified the organs at risk,such as lung,heart,esophagus,kidney,bladder,and ileum,and located specific cell types(i.e.,type II alveolar cells(AT2),myocardial cells,proximal tubule cells of the kidney,ileum and esophagus epithelial cells,and bladder urothelial cells),which are vulnerable to 2019-nCoV infection.Based on the findings,we constructed a risk map indicating the vulnerability of different organs to 2019-nCoV infection.This study may provide potential clues for further investigation of the pathogenesis and route of 2019-nCoV infection.Xin Zou Ke Chen Jiawei Zou Peiyi Han Jie Hao Zeguang Han 2020Frontiers of Medicine2020,14,2:193
6Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children.Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team 2020Neuroscience Bulletin2020,36,9:158

11The incidences and mortalities of major cancers in China, 2010显示文摘To estimate the cancer incidences and mortalities in China in 2010, the National Central Cancer Registry(NCCR) of China evaluated data for the year of 2010 from 145 qualified cancer registries covering 158,403,248 people(92,433,739 in urban areas and 65,969,509 in rural areas). The estimates of new cancer cases and cancer deaths were 3,093,039 and 1,956,622 in 2010, respectively. The percentage of morphologically verified cases were 67.11%; 2.99% of incident cases were identified through death certification only, with the mortality to incidence ratio of 0.61. The crude incidence was 235.23/100,000(268.65/100,000 in males and 200.21/100,000 in females). The age-standardized rates by Chinese standard population(ASR China) and by world standard population(ASR world) were 184.58/100,000 and 181.49/100,000, respectively, with a cumulative incidence(0-74 years old) of 21.11%. The crude cancer mortality was 148.81/100,000(186.37/100,000 in males and 109.42/100,000 in females). The ASR China and ASR world were 113.92/100,000 and 112.86/100,000, respectively, with a cumulative mortality of 12.78%. Lung, breast, gastric, liver, esophageal, colorectal, and cervical cancers were the most common cancers. Lung, liver, gastric, esophageal, colorectal, breast, and pancreatic cancers were the leading causes of cancer deaths. The coverage of cancer registration has rapidly increased in China in recent years and may reflect more accurate cancer burdens among populations living in different areas. Given the increasing cancer burden in the past decades, China should strengthen its cancer prevention and control.Wan-Qing Chen Rong-Shou Zheng Si-Wei Zhang Hong-Mei Zeng Xiao-Nong Zou 2014Chinese Journal of Cancer2014,33,8:62

13Generalized non-linear strength theory and transformed stress space显示文摘Based on the test data of frictional materials and previous research achievements in this field, a generalized non-linear strength theory (GNST) is proposed. It describes non-linear strength properties on the π-plane and the meridian plane using a unified formula, and it includes almost all the present non-linear strength theories, which can be used in just one material. The shape of failure function of the GNST is a smooth curve between the SMP criterion and the Mises criterion on the π-plane, and an exponential curve on the meridian plane. Through the transformed stress space based on the GNST, the combination of the GNST and various constitutive models using p and q as stress parameters can be realized simply and rationally in three-dimensional stress state.YAO Yangping LU Dechun ZHOU Annan ZOU Bo 2004Science China(Technological Sciences)2004,47,6:57

15Paracrine and endocrine actions of bone——the functions of secretory proteins from osteoblasts, osteocytes, and osteoclasts显示文摘The skeleton is a dynamic organ that is constantly remodeled. Proteins secreted from bone cells, namely osteoblasts, osteocytes,and osteoclasts exert regulation on osteoblastogenesis, osteclastogenesis, and angiogenesis in a paracrine manner. Osteoblasts secrete a range of different molecules including RANKL/OPG, M-CSF, SEMA3A, WNT5A, and WNT16 that regulate osteoclastogenesis. Osteoblasts also produce VEGFA that stimulates osteoblastogenesis and angiogenesis. Osteocytes produce sclerostin(SOST) that inhibits osteoblast differentiation and promotes osteoclast differentiation. Osteoclasts secrete factors including BMP6, CTHRC1, EFNB2, S1P, WNT10B, SEMA4D, and CT-1 that act on osteoblasts and osteocytes, and thereby influencea A osteogenesis. Osteoclast precursors produce the angiogenic factor PDGF-BB to promote the formation of Type H vessels, which then stimulate osteoblastogenesis. Besides, the evidences over the past decades show that at least three hormones or 'osteokines'from bone cells have endocrine functions. FGF23 is produced by osteoblasts and osteocytes and can regulate phosphate metabolism. Osteocalcin(OCN) secreted by osteoblasts regulates systemic glucose and energy metabolism, reproduction, and cognition. Lipocalin-2(LCN2) is secreted by osteoblasts and can influence energy metabolism by suppressing appetite in the brain.We review the recent progresses in the paracrine and endocrine functions of the secretory proteins of osteoblasts, osteocytes, and osteoclasts, revealing connections of the skeleton with other tissues and providing added insights into the pathogenesis of degenerative diseases affecting multiple organs and the drug discovery process.Yujiao Han Xiuling You Wenhui Xing Zhong Zhang Weiguo Zou 2018Bone Research2018,6,2:52
16Gallstone recurrence after successful percutaneous cholecystolithotomy:a 10-year follow-up of 439 cases显示文摘BACKGROUND: Stone recurrence is a major problem in the medication of gallstones with gallbladder preservation. The aim of this study was to determine the long-term recurrence rate of gallstones and the clinical outcome after successful percutaneous cholecystolithotomy (PCCL) treatment, and to investigate the possible risk factors for gallstone recurrence. METHODS: After successful PCCL for gallstones, 439 patients were followed up during a 10-year period. The long-term gallstone recurrence rate and clinical outcome were evaluated. Risk factors associated with stone recurrence were identified. RESULTS: Gallstone recurrence was detected in 182 of 439 PCCL patients, giving an overall recurrence rate of 41.46%. The cumulative gallstone recurrence rate for each of the 10 post-operative years was 9.57%, 18.91%, 27.33%, 34.14%, 37.59%, 39.86%, 41.90%, 42.73%, 42.85%, and 43.21%, respectively. Among these recurrent patients, 94 were asymptomatic, 80 suffered from nonspecific upper gastrointestinal symptoms and 8 suffered from abdominal pain or biliary colic. Thirty-eight of the 182 patients were retreated with cholecystectomy. The risk factors for stone recurrence included a family history of gallstones, preference for fatty food, accompanying liver disease, multiple stones and poor gallbladder function pre-PCCL. CONCLUSIONS: In this study, the overall recurrence rate of gallstone was 41.46% during a 10-year period. The highest frequency of gallstone recurrence was during the 5th to 6th postoperative years and then continued to slowly increase. Risk factors for stone recurrence varied.We suggest that the use of PCCL in patients with gallstones should be considered carefully because of stone recurrence.Zou, Yi-Ping Du, Ji-Dong Li, Wei-Min Xiao, Yin-Qi Xu, Hong-Bin Zheng, Fang Huang, Hui Liu, Hao-Run Li, Hu-Cheng 2007Hepatobiliary & Pancreatic Diseases International2007,6,2:43

18PREVALENCE AND RISK FACTORS OF PERIPHERAL ARTERIAL DISEASE IN DIABETIC PATIENTS OVER 50 YEARS OLD IN CHINA显示文摘Objective To investigate the prevalence of peripheral arterial disease (PAD) in China type 2 diabetic patients and to demonstrate the relationships between putative risk factors and PAD. Methods In total 1 397 type 2 diabetic patients aged 50 years and older were enrolled and determined ankle-brachial index (ABI) and brachial-ankle pulse wave velocity (baPWV) in 15 Class III Grade A hospitals in 7 major cities of China. Results Mean patient age was 63.7±8.2 years and mean duration of diabetes mellitus was 9.39±7.4 years. Two hundreds and seventy-two (19.47%) patients were diagnosed as PAD by ABI <0.9, 122 (18.37%) in male and 150 (20.46%) in female. PAD patients had a significantly longer duration of diabetes mellitus, higher hemoglobin Alc, and a significantly lower mean body mass index than non-PAD ones. Aging, smoking, and systolic blood pressure were found to be positively related with the prevalence of PAD. In terms of lipid profiles, no variable was found to relate with PAD. Notably, baPWV showed as the same significant guiding index for PAD, almost matched with ABI. Conclusions PAD is a common complication in China type 2 diabetic patients. Therefore, PAD screening and treatment should be emphasized for diabetic patients with high risk factors.Heng Guan Yong-jun Li Zhang-rong XU Guang-wei Li Xiao-hui Guo Zhi-min Liu Da-jin Zou Hui-li Xing Wei Liu Zheng-yan Sheng Hao-ming Tian Da-long Zhu De-min YU Wei-te Zhuang Lu-lu Chen Jian-ping Weng 2007Chinese Medical Sciences Journal2007,22,2:41
