4Prediction and systematic study of protein-protein interaction networks of Leptospira interrogans显示文摘Leptospira interrogans serovar Lai is a pathogenic bacterium that causes a spirochetal zoonosis in humans and some animals. With its complete genome sequence available, it is possible to analyze protein-protein interactions from a whole- genome standpoint. Here we combine four recently developed computational approaches (gene fusion method, gene neighbor method, phylogenetic profiles method, and operon method) to predict protein-pro- tein interaction networks of Leptospira interrogans strain Lai. Through comprehensive analysis on in- teractions among proteins of motility and chemotaxis system, signal transduction, lipopolysaccaride bio- synthesis and a series of proteins related to adhesion and invasion, we provided information for further studying on its pathogenic mechanism. In addition, we also assigned 203 previously uncharacterized proteins with possible functions based on the known functions of its interacting partners. This work is helpful for further investigating L. interrogans strain Lai.SUN Jingchun XU Jinlin CAO Jianping LIU Qi GUO Xiaokui SHI Tieliu LI Yixue 2006Chinese Science Bulletin2006,51,11:3

6High prevalence of pathogenic Leptospira in wild and domesticated animals in an endemic area of China显示文摘Objective:To assess the prevalence of Leptospira detected in wildlife and domesticated animals in Jiangxi Province,China,in 2009.Methods:Urine samples from 28 buffaloes and kidney samples from 50 pigs,50 dogs and 38 rats were collected from Fuliang and Shangrao County,Jiangxi Province,China,in October 2009.Polymerase chain reaction(PCR) and culture analyses were used to detect Leptospira.The cultured isolates were typed using the microscopic agglutination lest(MAT).Results:The results showed that rats potentially serve as the main reservoir of leptospiral infection,followed by dogs.Although 16%of rats(6/38) were positive using culture analysis,PCR analysis using the diagnostic primers G1/G2 and B64Ⅰ/B64Ⅱor lipLS2 showed identification as 50%and 24%,respectively,of the rat samples as positive for the presence of leptospiral DNA.Conclusions:PCR-based detection of leptospiral DNA in infected kidney tissues of reservoirs is more efficient when using G1/G2 primers than lipL32 primers. However,the latter primers have a potential application for detection in urine samples.The alarmingly high prevalence of leptospiral DMA in the wild rat population near human habitation underscores the utility of routine Leptospira surveillance,preferably using PCR methods,which are more sensitive than traditional culture-based methods.Wang Yalin Zeng Lingbing Yang Hongliang Xu Jianmin Zhang Xiangyan Guo Xiaokui Pal Utpal Qin Jinhong 2011Asian Pacific Journal of Tropical Medicine2011,4,11:2
7Global antimicrobial resistance:a system-wide comprehensive investigation using the Global One Health Index显示文摘Background:Antimicrobial resistance(AMR)is one of the top ten global public health challenges.However,given the lack of a comprehensive assessment of worldwide AMR status,our objective is to develop a One Health-based system-wide evaluation tool on global AMR.Methods:We have further developed the three-hierarchical Global One Health Index(GOHI)-AMR indicator scheme,which consists of five key indicators,17 indicators,and 49 sub-indicators,by incorporating 146 countries'data from diverse authoritative databases,including WHO's Global Antimicrobial Resistance and Use Surveillance System(GLASS)and the European CDC.We investigated the overall-or sub-rankings of GOHI-AMR at the international/regional/national levels for data preprocessing and score calculation utilizing the existing GOHI methodology.Additionally,a correlation analysis was conducted between the GOHI-AMR and other socioeconomic factors.Results:The average GOHI-AMR score for 146 countries is 38.45.As expected,high-income countries(HICs)outperform the other three income groups on overall rankings and all five key indicators of GOHI-AMR,whereas lowincome countries unexpectedly outperform upper-middle-income countries and lower-middle-income countries on the antibiotics-resistant key indicator(ARR)and ARR-subordinate indicators,including carbapenem-,β-lactam-,and quinolone resistance,and even HICs on aminoglycoside resistance.There were no significant differences among the four groups on the environmental-monitoring indicator(P>0.05).GOHI-AMR was positively correlated with gross domestic product,life expectancy,and AMR-related publications,but negatively with natural growth rate and chronic respiratory disease.In contrast to Cyprus,the remarkably lower prevalence of'ESKAPE pathogens'in high-scoring Sweden and Denmark highlights Europe's huge gaps.China and Russia outperformed the other three BRICS countries on all key indicators,particularly India's ARR and Brazil's AMR laboratory network and coordination capacity.Furthermore,significant internal disparities in carbapenem-resistant Klebsiella pneumoniae(CRKP)and methicillin-resistant Staphylococcus aureus(MRSA)prevalence were observed between China and the USA,with MRSA prevalence both gradually declining,whereas CRKP prevalence has been declining in the USA but increasing in China,consistent with higher carbapenems-related indicator'performance in USA.Conclusions:GOHI-AMR is the most comprehensive tool currently available for the assessment of AMR status worldwide.We discovered unique features impacting AMR in each country and offered precise recommendations to improve the capacity to tackle AMR in low-ranking countries.Nan Zhou Zile Cheng Xiaoxi Zhang Chao Lv Chaoyi Guo Haodong Liu Ke Dong Yan Zhang Chang Liu Yunfu Chang Sheng Chen Xiaokui Guo Xiao-Nong Zhou Min Li Yongzhang Zhu 2022Infectious Diseases of Poverty2022,11,4:2

14Consensus on potential biomarkers developed for use in clinical tests for schizophrenia显示文摘Background Schizophrenia is a serious mental illness affecting approximately 20 million individuals globally.Both genetic and environmental factors contribute to the illness.If left undiagnosed and untreated,schizophrenia results in impaired social function,repeated hospital admissions,reduced quality of life and decreased life expectancy.Clinical diagnosis largely relies on subjective evidence,including self-reported experiences,and reported behavioural abnormalities followed by psychiatric evaluation.In addition,psychoses may occur along with other conditions,and the symptoms are often episodic and transient,posing a significant challenge to the precision of diagnosis.Therefore,objective,specific tests using biomarkers are urgently needed for differential diagnosis of schizophrenia in clinical practice.Aims We aimed to provide evidence-based and consensus-based recommendations,with a summary of laboratory measurements that could potentially be used as biomarkers for schizophrenia,and to discuss directions for future research.Methods We searched publications within the last 10 years with the following keywords:‘schizophrenia’,‘gene’,‘inflammation’,‘neurotransmitter’,‘protein marker’,‘gut microbiota’,‘pharmacogenomics’and‘biomarker’.A draft of the consensus was discussed and agreed on by all authors at a round table session.Results We summarised the characteristics of candidate diagnostic markers for schizophrenia,including genetic,inflammatory,neurotransmitter,peripheral protein,pharmacogenomic and gut microbiota markers.We also proposed a novel laboratory process for diagnosing schizophrenia in clinical practice based on the evidence summarised in this paper.Conclusions Further efforts are needed to identify schizophrenia-specific genetic and epigenetic markers for precise diagnosis,differential diagnosis and ethnicity-specific markers for the Chinese population.The development of novel laboratory techniques is making it possible to use these biomarkers clinically to diagnose disease.Ping Lin Junyu Sun Xiaoyan Lou Dan Li Yun Shi Zhenhua Li Peijun Ma Ping Li Shuzi Chen Weifeng Jin Shuai Liu Qing Chen Qiong Gao Lili Zhu Jie Xu Mengyuan Zhu Mengxia Wang Kangyi Liang Ling Zhao Huabin Xu Ke Dong Qingtian Li Xunjia Cheng Jinghong Chen Xiaokui Guo 2022General Psychiatry2022,35,1:1

16Dynamic antimicrobial resistant patterns of Escherichia coli from healthy poultry and swine over 10 years in Chongming Island,Shanghai显示文摘Background:Antimicrobial resistance(AMR)is one of the greatest threats to animal and public health.Here,we conducted a dynamic surveillance of Escherichia coli on Chongming Island in Shanghai during 2009-2021 to identify the characteristics and trends of Chongming’s AMR pandemic.Methods:Rectal(cloaca)swabs from four poultry and nine swine farms(Chongming Island,2009-2021)were collected for E.coli strains acquisition.The micro-broth dilution method was used to test antimicrobial susceptibility of E.coli isolates against 10 antimicrobial classes including 15 antimicrobials.Utilizing generalized linear mixed models(GLMMs)and co-occurrence analyses,we further explored the multiple-drug-resistance(MDR)combinations and dynamic patterns of E.coli over 10 years in two food animals.Results:Total of 863 MDR isolates were found among 945 collected E.coli isolates,337 from poultry and 608 from swine.Both isolates exhibited high resistant rates(>70%)to tetracyclines,phenicols,sulfonamides,penicillins,and aminoglycosides(only in swine).The resistant rates of swine isolates to penicillins,aminoglycosides,tetracyclines,phenicols,and polymyxins were significantly higher than those of poultry isolates,whereas resistance to fluoroquinolones was reversed.Resistance to polymyxins decreased similarly in swine(42.4%in 2009 to 0.0%in 2021)and poultry isolates(from 16.5%to 0.0%).However,resistance to other seven antimicrobial classes(excluding carbapenems and penicillins)declined dramatically in swine isolates,particularly fluoroquinolones(from 80.5%to 14.4%),and tendencies of resistance to the seven classes showed markedly divergent patterns in poultry isolates.Using Poisson GLMMs,the AMR carriage since 2016 was significantly lower than that of 2009(odds ratio<1),indicating a decline in the risk of MDR emergence.Furthermore,despite the highly diverse MDR profiles,co-occurrence analysis identified two prominent MDR clusters of penicillins-phenicols-fluoroquinolones in poultry and aminoglycosides-tetracyclines-sulfonamides-phenicols in swine.Conclusions:Our study uncovered vastly distinct AMR patterns and dynamic tendencies of poultry and swine E.coli isolates from Chongming.Meanwhile,Chongming’s AMR status has ameliorated,as indicated by the decline in antimicrobials prevalence(particularly in swine),lower likelihood of MDR emergence and low carbapenem-,cephalosporin-,and polymyxin resistance.Importantly,this surveillance results are the vital basis for future policy development in Chongming and Shanghai.Chao Lv Jun Shang Wengang Zhang Bingqing Sun Min Li Chaoyi Guo Nan Zhou Xiaokui Guo Shixin Huang Yongzhang Zhu 2022Infectious Diseases of Poverty2022,11,5:0
