2Effects of process parameters on pore structure of semi-coke prepared by solid heat carrier with dry distillation显示文摘The semi-coke was prepared by solid heat carrier with dry distillation in single factor method. The pore structures of raw coal and semi-coke were characterized by Brunauer-Emmett-Teller (BET) and scanning electron microscope (SEM). The results show that the adsorption and desorption isotherm of semi-coke are not coincident. There was a wide pore distribution on the semi-coke, in which mesopores and micropores account for a considerable proportion. Also there are many more secondary pores. With the increase of the final temperature of heat carrier and constant temperature, as well as the decrease of volume ratio of coal and hot carrier reactor, specific surface area and pore volume of semi-coke increased rapidly first and then decreased and finally increased, along with the rapidly reduction of average pore size. SEM photos show that the surface of semi-coke becomes increasingly rough and glossy.Zhou, Guoli Wu, Jianjun Miao, Zhenyong Hu, Xuelian Li, Xia Shi, Xin Cai, Zhidan Shang, Yukun 2013International Journal of Mining Science and Technology2013,23,3:20
3Association between Ambient Air Pollution and Hospital Emergency Admissions for Respiratory and Cardiovascular Diseases in Beijing: a Time Series Study显示文摘Objective To investigate the association between ambient air pollution and hospital emergency admissions in Beijing. Methods In this study, a semi-parametric generalized additive model(GAM) was used to evaluate the specific influences of air pollutants(PM10, SO2, and NO2) on hospital emergency admissions with different lag structures from 2009 to 2011, the sex and age specific influences of air pollution and the modifying effect of seasons on air pollution to analyze the possible interaction. Results It was found that a 10 μg/m3 increase in concentration of PM10 at lag 03 day, SO2 and NO2 at lag 0 day were associated with an increase of 0.88%, 0.76%, and 1.82% respectively in overall emergency admissions. A 10 μg/m3 increase in concentration of PM10, SO2 and NO2 at lag 5 day were associated with an increase of 1.39%, 1.56%, and 1.18% respectively in cardiovascular disease emergency admissions. For lag 02, a 10 μg/m3 increase in concentration of PM10, SO2 and NO2 were associated with 1.72%, 1.34%, and 2.57% increases respectively in respiratory disease emergency admissions. Conclusion This study further confirmed that short-term exposure to ambient air pollution was associated with increased risk of hospital emergency admissions in Beijing.ZHANG Ying WANG Shi Gong MA Yu Xia SHANG Ke Zheng CHENG Yi Fan LI Xu NING Gui Cai ZHAO Wen Jing LI Nai Rong 2015Biomedical and Environmental Sciences2015,28,5:18

7Grape Seed Proanthocyanidin Extract Alleviates Arsenic-induced Oxidative Reproductive Toxicity in Male Mice显示文摘Objective To determine the ability of grape seed proanthocyanidin extract(GSPE) in alleviating arsenic-induced reproductive toxicity. Methods Sixty male Kunming mice received the following treatments by gavage: normal saline solution(control); arsenic trioxide(ATO; 4 mg/kg); GSPE(400 mg/kg); ATO+GSPE(100 mg/kg); ATO+GSPE(200 mg/kg) and ATO+GSPE(400 mg/kg). Thereafter, the mice were sacrificed and weighed, and the testis was examined for pathological changes. Nuclear factor(erythroid-derived 2)-like 2(Nrf2), heme oxygenase 1(HO1), glutathione S-transferase(GST), NAD(P)H dehydrogenase, and quinone 1(NQO1) expression in the testis was detected by real-time PCR. Superoxide dismutase(SOD), glutathione(GSH), total antioxidative capability(T-AOC), malondialdehyde(MDA), 8-hydroxydeoxyguanosine(8-OHd G), and reproductive indexes were analyzed. Results ATO-treated mice showed a significantly decreased sperm count and testis somatic index and activity levels of SOD, GSH, and T-AOC than control group. Compared to the ATO-treated group, ATO +GSPE group showed recovery of the measured parameters. Mice treated with ATO+high-dose GSPE showed the highest level of m RNA expression of Nrf2, HO, NQO1, and GST. Conclusion GSPE alleviates oxidative stress damage in mouse testis by activating Nrf2 signaling, thus counteracting arsenic-induced reproductive toxicity.LI Shu Gang DING Yu Song NIU Qiang XU Shang Zhi PANG Li Juan MA Ru Lin JING Ming Xia FENG Gang Ling LIU Jia Ming GUO Shu Xia 2015Biomedical and Environmental Sciences2015,28,4:14

9Application of community-based and integrated strategy to reduce malaria disease burden in southern Tanzania:the study protocol of China-UK-Tanzania pilot project on malaria control显示文摘Background:During the past six decades,remarkable success on malaria control has been made in China.The major experience could be shared with other malaria endemic countries including Tanzania with high malaria burden.Especially,China’s 1-3-7 model for malaria elimination is one of the most important refined experiences from many years’efforts and key innovation measures for malaria elimination in China.Methods:The China-UK-Tanzania pilot project on malaria control was implemented from April,2015 to June,2018,which was an operational research with two communities receiving the proposed interventions and two comparable communities serving as control sites.The World Health Organization'Test,Treat,Track'(WHO-T3)Initiative,which calls for every suspected case to receive a diagnostic test,every confirmed case to be treated,and for the disease to be tracked,was integrated with Chinese experiences on malaria control and elimination for exploration of a proper model tailored to the local settings.Application of China’s 1-3-7 model integrating with WHO-T3 initiative and local resources aiming at reducing the burden of malaria in terms of morbidity and mortality by 30%in the intervention communities in comparison with that at the baseline survey.Discussion:The China-UK-Tanzania pilot project on malaria control was that at China’s first pilot project on malaria control in Africa,exploring the feasibility of Chinese experiences by China-Africa collaboration,which is expected that the strategies and approaches used in this project could be potential for scaling up in Tanzania and African countries,and contribute to the acceleration of malaria control and elimination in Africa.Duoquan Wang Prosper Chaki Yeromin Mlacha Tegemeo Gavana Mihayo Gabriel Michael Rashid Khatibu Jun Feng Zheng-Bin Zhou Kang-Ming Lin Shang Xia He Yan Deus Ishengoma Susan Rumisha Sigbert Mkude Renata Mandike Frank Chacky Charles Dismasi Salim Abdulla Honorati Masanja Ning Xiao Xiao-Nong Zhou 2019Infectious Diseases of Poverty2019,8,1:12
10Inferring the potential risks of H7N9 infection by spatiotemporally characterizing bird migration and poultry distribution in eastern China显示文摘Background:In view of the rapid geographic spread and the increasing number of confirmed cases of novel influenza A(H7N9)virus infections in eastern China,we developed a diffusion model to spatiotemporally characterize the impacts of bird migration and poultry distribution on the geographic spread of H7N9 infection.Methods:Three types of infection risks were estimated for 12 weeks,from February 4 to April 28,2013,including(i)the risk caused by bird migration,(ii)the risk caused by poultry distribution,and(iii)the integrated risk caused by both bird migration and poultry distribution.To achieve this,we first developed a method for estimating the likelihood of bird migration based on available environmental and meteorological data.Then,we adopted a computational mobility model to estimate poultry distribution based on annual poultry production and consumption of each province/municipality.Finally,the spatiotemporal risk maps were created based on the integrated impacts of both bird migration and poultry distribution.Results:In the study of risk estimation caused by bird migration,the likelihood matrix was estimated based on the 7-day temperature,from February 4 to April 28,2013.It was found the estimated migrant birds mainly appear in the southeastern provinces of Zhejiang,Shanghai and Jiangsu during Weeks 1 to 4,and Week 6,followed by appearing in central eastern provinces of Shandong,Hebei,Beijing,and Tianjin during Weeks 7 to 9,and finally in northeastern provinces of Liaoning,Jilin,and Heilongjiang during Weeks 10 to 12.In the study of risk caused by poultry distribution,poultry distribution matrix was created to show the probability of poultry distribution.In spite of the fact that the majority of the initial infections were reported in Shanghai and Jiangsu,the relative risk of H7N9 infection estimated based on the poultry distribution model predicted that Jiangsu may have a slightly higher likelihood of H7N9 infection than those in Zhejiang and Shanghai,if we only take the probability of poultry distribution into consideration.In the study of integrated risk caused by both bird migration and poultry distribution,the higher risk in southeastern provinces occurred during the first 8 weeks,and that in central eastern provinces appeared during Weeks 8 to 12,and that in northeastern provinces since Week 12.Therefore,it is necessary to regulate the poultry markets as long as the poultry-to-poultry transmission is not so well understood.Conclusion:With reference to the reported infection cases,the demonstrated risk mapping results will provide guidance in active surveillance and control of human H7N9 infections by taking intensive intervention in poultry markets.Benyun Shi Shang Xia Guo-Jing Yang Xiao-Nong Zhou Jiming Liu 2013Infectious Diseases of Poverty2013,2,1:8

12Antibiotic resistance and molecular characterization of diarrheagenic Escherichia coli and non-typhoidal Salmonella strains isolated from infections in Southwest China显示文摘Background:Bacterial diarrhea is one of the most common causes for medical consultations,mortality and morbidity in the world.Diarrheagenic Escherichia coli(DEC)and non-typhoidal Salmonella(NTS)are major intestinal pathogens in developing countries,and the indiscriminate use of antibiotics has greatly contributed to resistant strains.Hence,the aim of the present study is to identify the antimicrobial resistance patterns and the molecular characteristics of DEC and NTS in southwest,China.Methods:1121 diarrheal patients and 319 non-diarrheal subjects across all age groups were recruited from four sentinel hospitals from June 2014 to July 2015 in Kunming City,Yunnan Province.Each stool specimen was collected to detect DEC and NTS with standard microbiological and molecular methods.Antimicrobial resistance testing was performed with the Kirby-Bauer disk diffusion method,and the standards for antimicrobial susceptibility testing complied with the Clinical and Laboratory Standards Institute(CLSI).Molecular characterization of strains was carried out using pulsed-field gel electrophoresis(PFGE).A structured questionnaire was used to record basic epidemiological data(e.g.sex,age,residence,season,etc.).Data were analyzed using Chi-square or Fisher’s exact test.Results:DEC was detected in 127(11.33%)diarrhea cases and 9(2.82%)non-diarrheal cases(χ^(2)=20.69,P<0.001,OR=4.36,95%CI:2.19-8.65),and the prevalence of NTS isolated from diarrhea cases was higher than that of non-diarrheal cases across all age groups(n=42,3.75%,n=1,0.31%,χ^(2)=10.10,P=0.002,OR=12.38,95%CI:1.70-90.29).The rates of resistance to ten antibiotics of DEC and NTS showed significant differences(χ^(2)=386.77,P<0.001;χ^(2)=191.16,P<0.001).The rates of resistance to Amoxicillin and Clavulafiate(AMC),Cephalothin(CEP),Gentamicin(GEN)and Sulfamethoxazole-Trimethoprim(SXT)of DEC isolated from diarrhea cases were higher than those of NTS isolated from diarrhea patients(37.01%vs 14.29%,χ^(2)=7.57,P=0.006;29.92%vs 11.90%,χ^(2)=5.40,P=0.02;37.01%vs 11.90%,χ^(2)=5.80,P=0.016;62.20%vs 26.19%,χ^(2)=16.44,P<0.001;respectively).Ciprofloxacin(CIP)was the most sensitive antibiotic for DEC and NTS strains isolated from diarrhea cases.Resistance rates of DEC isolates from cases and controls to more than three kinds antimicrobials(multidrug resistance,MDR)showed no significant differences(81.10%vs 88.89%,P=0.33).Pulsotype patterns of DEC strains were highly diverse;however,the pulsotype pattern of NTS strains was closely related to the serotype.The pattern of S.enteritidis was highly similar,but the S.enterica Typhimurium strain was discrete.Conclusions:Antibiotic resistance of Enterobacteriaceae is of great concern.The societal effects of antibiotic use justify strict monitoring to combat increases in antimicrobial resistance.Molecular epidemiology and systematic epidemiological investigation can provide accurate evidence for tracking the infection source.Shun-Xian Zhang Yong-Ming Zhou Li-Guang Tian Jia-Xu Chen Rita Tinoco-Torres Emmanuel Serrano Shi-Zhu Li Shao-Hong Chen Lin Ai Jun-Hu Chen Shang Xia Yan Lu Shan Lv Xue-Jiao Teng Wen Xu Wen-Peng Gu Si-Tang Gong Xiao-Nong Zhou Lan-Lan Geng Wei Hu 2018Infectious Diseases of Poverty2018,7,1:7
13Risk assessment of malaria transmission at the border area of China and Myanmar显示文摘Background:In order to achieve the goal of malaria elimination,the Chinese government launched the National Malaria Elimination Programme in 2010.However,as a result of increasing cross-border population movements,the risk of imported malaria cases still exists at the border areas of China,resulting in a potential threat of local transmission.The focus of this paper is to assess the Plasmodium vivax incidences in Tengchong,Yunnan Province,at the border areas of China and Myanmar.Methods:Time series of P.vivax incidences in Tengchong from 2006 to 2010 are collected from the web-based China Information System for Disease Control and Prevention,which are further separated into time series of imported and local cases.First,the seasonal and trend decomposition are performed on time series of imported cases using Loess method.Then,the impact of climatic factors on the local transmission of P.vivax is assessed using both linear regression models(LRM)and generalized additive models(GAM).Specifically,the notion of vectorial capacity(VCAP)is used to estimate the transmission potential of P.vivax at different locations,which is calculated based on temperature and rainfall collected from China Meteorological Administration.Results:Comparing with Ruili County,the seasonal pattern of imported cases in Tengchong is different:Tengchong has only one peak,while Ruili has two peaks during each year.This may be due to the different cross-border behaviors of peoples in two locations.The vectorial capacity together with the imported cases and the average humidity,can well explain the local incidences of P.vivax through both LRM and GAM methods.Moreover,the maximum daily temperature is verified to be more suitable to calculate VCAP than the minimal and average temperature in Tengchong County.Conclusion:To achieve malaria elimination in China,the assessment results in this paper will provide further guidance in active surveillance and control of malaria at the border areas of China and Myanmar.Benyun Shi Jinxin Zheng Hongjun Qiu Guo-Jing Yang Shang Xia Xiao-Nong Zhou 2017Infectious Diseases of Poverty2017,6,1:6
14Infective viruses produced from full-length complementary DNA of swine vesicular disease viruses HK/70 strain显示文摘The full-length cDNA clone of swine vesicular disease virus HK/70 strain named pSVOK12 was constructed in order to study the antigenicity, replication, maturation and pathogenicity of swine vesicular disease virus. In vitro transcription RNA from pSVOK12 transfected IBRS-2 cells and the re- covered virus RNA were isolated and sequenced, then indirect hemagglutination test, indirect im- munofluorescence assays, eleectron microscope test, 50% tissue culture infecting dose (TCID50) assays and mouse virulence studies were performed to study the antigenicity and virulence of the recovered virus. The result showed that the infectious clones we ob- tained and the virus derived from pSVOK12 had the same biological properties as the parental strain HK/70. The full-length infectious cDNA clone, pSVOK12, will be very useful in studies of the anti- genicity, virulence, pathogenesis, maturation and replication of SVDV.ZHENG Haixue LIU Xiangtao SHANG Youiun WU Jinyan BAI Xingwen JIN Ye SUN Shiqi GUO Huichen TIAN Hong FENG Xia YIN Shuanghui GUO Jianhong CONG Guozheng LIU Zaixin CHANG Huiyun MA Junwu XIE Qingge 2006Chinese Science Bulletin2006,51,17:6
15Cloning and expression analysis of a dirigent protein gene from the resurrection plant Boea hygrometrica显示文摘Resurrection plants are tolerant to extreme dehydration and are useful model systems to study genes that play a role in drought tolerance. A gene fragment encoding a dirigent protein that is predicted to function in lignin biosynthesis was identified from leaves of the resurrection plant Boea hygrometrica via cDNA microarray screening. A cDNA, designated BhDIR1, containing the complete predicted open reading frame, was obtained by 50-RACE. BhDIR1 transcripts were found to be accumulated in response to changes in plant dehydration status, exogenously applied phytohormones and signaling molecules, and temperature stresses. BhDIR1 encodes a protein of 199 amino acids, which shows 20-40% similarity to dirigent proteins reported from other plants. BhDIR1 is predicted to contain a cleavable signal peptide at the N-terminal, and its plasma membrane/cell wall localization was confirmed using a GFP fusion protein assay. Consistent with this discovery, the acid-soluble lignin content decreased in dehydrated B. hygrometrica leaves. Taken together, our results indicate a protective role for a dirigent protein in response to drought stress by changing the physical characters of lignin which in turn is predicted to affect the mechanical strength and flexibility of the plant cell wall.Renhua Wu, Lili Wang, Zhi Wang, Haihong Shang, Xia Liu, Yan Zhu, Dongdong Qi, Xin Deng * Key Laboratory of Photosynthesis and Environmental Molecular Physiology, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China 2009Progress in Natural Science:Materials International2009,19,3:6
16Infestation risk of the intermediate snail host of Schistosomajaponicum in the Yangtze River Basin: improved results by spatial reassessment and a random forest approach显示文摘Background:Oncomelania hupensis is only intermediate snail host of Schistosomajaponicum,and distribution of 0.hupensis is an important indicator for the surveillance of schistosomiasis.This study explored the feasibility of a random forest algorithm weighted by spatial distance for risk prediction of schistosomiasis distribution in the Yangtze River Basin in China,with the aim to produce an improved precision reference for the national schistosomiasis control programme by reducing the number of snail survey sites without losing predictive accuracy.Methods:The snail presence and absence records were collected from Anhui,Hunan,Hubei,Jiangxi and Jiangsu provinces in 2018.A machine learning of random forest algorithm based on a set of environmental and climatic variables was developed to predict the breeding sites of the 0.hupensis intermediated snail host of S.japonicum.Different spatial sizes of a hexagonal grid system were compared to estimate the need for required snail sampling sites.The predictive accuracy related to geographic distances between snail sampling sites was estimated by calculating Kappa and the area under the curve(AUC).Results:The highest accuracy(AUC=0.889 and Kappa=0.618)was achieved at the 5 km distance weight.The five factors with the strongest correlation to 0.hupensis infestation probability were:(1)distance to lake(48.9%),(2)distance to river(36.6%),(3)isothermality(29.5%),(4)mean daily difference in temperature(28.1%),and(5)altitude(26.0%).The risk map showed that areas characterized by snail infestation were mainly located along the Yangtze River,with the highest probability in the dividing,slow-flowing river arms in the middle and lower reaches of the Yangtze River in Anhui,followed by areas near the shores of China's two main lakes,the Dongting Lake in Hunan and Hubei and the Poyang Lake in Jiangxi.Conelusions:Applying the machine learning of random forest algorithm made it feasible to precisely predict snail infestation probability,an approach that could improve the sensitivity of the Chinese schistosome surveillance.system.Redesign of the snail surveillance system by spatial bias correction of 0.hupensis infestation in the Yangtze River Basin to reduce the number of sites required to investigate from 2369 to 1747.Jin-Xin Zheng Shang Xia Shan Lv Yi Zhang Robert Bergquist Xiao-Nong Zhou 2021Infectious Diseases of Poverty2021,10,3:6

19The Benefit Risk Assessment of Consumption of Marine Species Based on Benefit-Risk Analysis for Foods(BRAFO)-tiered Approach显示文摘Objective To assess the net health effect caused by the consumption of specific marine species based on Benefit-Risk Analysis for Foods(BRAFO)-tiered approach. Methods Twenty species were collected from the Zhoushan Archipelago, China. Concentrations of n-3 long-chain polyunsaturated fatty acids, methyl mercury(Me Hg), and dioxin-like compounds(DLCs) in the samples were analyzed for benefit risk assessment based on BRAFO-tiered approach. Results Based on the BRAFO-tiered approach, reference scenario(no intake) and alternative scenario(intake of specific species of 200 g/week) were determined. The exposure to Me Hg/DLCs via alternative scenario of all studied species did not exceed provisional tolerable weekly/monthly intake. However, the adult population with high DLCs exposure in China would significantly exceed the upper limit of DLCs via an additional alternative scenario of some species such as Auxis thazard. The results of deterministic computation showed that alternative scenario of all studied species generated clear net beneficial effects on death prevention and child IQ gain. Conclusion The alternative scenario of all studied species could be recommended to population with average DLCs exposure, and the reference scenario of species with relatively high DLCs concentration could be recommended to population exposed to high DLCs.GAO Yi Xiong ZHANG Hong Xia LI Jing Guang ZHANG Lei YU Xin Wei HE Jia Lu SHANG Xiao Hong ZHAO Yun Feng WU Yong Ning 2015Biomedical and Environmental Sciences2015,28,4:5
20Establishment and validation of a computer-assisted colonic polyp localization system based on deep learning显示文摘BACKGROUND Artificial intelligence in colonoscopy is an emerging field,and its application may help colonoscopists improve inspection quality and reduce the rate of missed polyps and adenomas.Several deep learning-based computer-assisted detection(CADe)techniques were established from small single-center datasets,and unrepresentative learning materials might confine their application and generalization in wide practice.Although CADes have been reported to identify polyps in colonoscopic images and videos in real time,their diagnostic performance deserves to be further validated in clinical practice.AIM To train and test a CADe based on multicenter high-quality images of polyps and preliminarily validate it in clinical colonoscopies.METHODS With high-quality screening and labeling from 55 qualified colonoscopists,a dataset consisting of over 71000 images from 20 centers was used to train and test a deep learning-based CADe.In addition,the real-time diagnostic performance of CADe was tested frame by frame in 47 unaltered full-ranged videos that contained 86 histologically confirmed polyps.Finally,we conducted a selfcontrolled observational study to validate the diagnostic performance of CADe in real-world colonoscopy with the main outcome measure of polyps per colonoscopy in Changhai Hospital.RESULTS The CADe was able to identify polyps in the test dataset with 95.0%sensitivity and 99.1%specificity.For colonoscopy videos,all 86 polyps were detected with 92.2%sensitivity and 93.6%specificity in frame-by-frame analysis.In the prospective validation,the sensitivity of CAD in identifying polyps was 98.4%(185/188).Folds,reflections of light and fecal fluid were the main causes of false positives in both the test dataset and clinical colonoscopies.Colonoscopists can detect more polyps(0.90 vs 0.82,P<0.001)and adenomas(0.32 vs 0.30,P=0.045)with the aid of CADe,particularly polyps<5 mm and flat polyps(0.65 vs 0.57,P<0.001;0.74 vs 0.67,P=0.001,respectively).However,high efficacy is not realized in colonoscopies with inadequate bowel preparation and withdrawal time(P=0.32;P=0.16,respectively).CONCLUSION CADe is feasible in the clinical setting and might help endoscopists detect more polyps and adenomas,and further confirmation is warranted.Sheng-Bing Zhao Wei Yang Shu-Ling Wang Peng Pan Run-Dong Wang Xin Chang Zhong-Qian Sun Xing-Hui Fu Hong Shang Jian-Rong Wu Li-Zhu Chen Jia Chang Pu Song Ying-Lei Miao Shui-Xiang He Lin Miao Hui-Qing Jiang Wen Wang Xia Yang Yuan-Hang Dong Han Lin Yan Chen Jie Gao Qian-Qian Meng Zhen-Dong Jin Zhao-Shen Li Yu Bai 2021World Journal of Gastroenterology2021,27,31:5
