| 1 | Molecular Epidemiological Characteristics of Streptococcus pyogenes Strains Involved in an Outbreak of Scarlet Fever in China,2011显示文摘Objective To investigate molecular characterization of streptococcus pyogenes isolates involved in an outbreak of scarlet fever in China in 2011.Methods 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.Results 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 emml (14.9%) accounted for approximately 94%of all the isolates.The speA gene was all negative in emm12 isolates and positive in emml isolates.All strains were resistant to erythromycin,and 89.4%of them were resistant to erythromycin,tracycline,and clindamycin simultaneously.Conclusion 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. | YOU Yuan Hai SONG Yan Yan YAN Xiao Mei WANG Hai Bin ZHANG Meng Han TAO Xiao Xia Li Lei Lei ZHANG Yu Xin JIANG Xi Hong ZHANG Bing Hua ZHOU Hao XIAO Di JIN Lian Mei FENG Zi Jian LUO Feng Ji ZHANG Jian Zhong | 2013 | Biomedical and Environmental Sciences2013，26，11： | 15 |
| 2 | Association between Low-density Lipoprotein Receptor-related Protein 5 Polymorphisms and Type 2 Diabetes Mellitus in Han Chinese:a Case-control Study显示文摘Objective To investigate the association between low-density lipoprotein receptor-related protein 5(LRP5) variants(rs12363572 and rs4930588) and type 2 diabetes mellitus(T2DM) in Han Chinese. Methods A total of 1842 T2 DM cases(507 newly diagnosed cases and 1335 previously diagnosed cases) and 7777 controls were included in this case-control study. PCR-RFLP was conducted to detect the genotype of the two single nucleotide polymorphisms(SNPs). Odds ratios(ORs) and 95% confidence intervals(95% CIs) were calculated to describe the strength of the association by logistic regression. Results In the study subjects, neither rs12363572 nor rs4930588 was significantly associated with T2 DM, even after adjusting for relevant covariates. When stratified by body mass index(BMI), the two SNPs were also not associated with T2 DM. Among the 3 common haplotypes, only haplotype TT was associated with reduced risk of T2DM(OR 0.820, 95% CI 0.732-0.919). In addition, rs12363572 was associated with BMI(P<0.001) and rs4930588 was associated with triglyceride levels(P=0.043) in 507 newly diagnosed T2 DM cases but not in healthy controls. Conclusion No LRP5 variant was found to be associated with T2 DM in Han Chinese, but haplotype TT was found to be associated with T2 DM. | YOU Hai Fei ZHAO Jing Zhi ZHAI Yu Jia YIN Lei PANG Chao LUO Xin Ping ZHANG Ming WANG Jin Jin LI Lin Lin WANG Yan WANG Qian WANG Bing Yuan REN Yong Cheng HU Dong Sheng | 2015 | Biomedical and Environmental Sciences2015，28，7： | 4 |
| 3 | Molecular Epidemiological Analysis of Group A Streptococci Isolated from Children in Chaoyang District of Beijing, 2011:emm Types, Virulence Factor Genes and Erythromycin Resistant Genes显示文摘Group A streptococcus(GAS)causes a wide range of diseases in the human population.GAS diseases are more common in children than in adults,with clinical manifestations ranging from pharyngitis and impetigo to invasive infections and post streptococcal sequelae,such as acute rheumatic fever and acute post-streptococcal glomerulonephritis[1].GAS harbors a host of virulence factors that contribute to its complex pathogenicity and differences in the disease severity and frequency.M protein,one of the major virulence factors,is encoded by the emm gene induces a type of specific host immune response and confers antiphagocytic properties.Sequence analysis of the emm gene has become an | WANG Hai Bin SONG Yan Yan YOU Yuan Hai WANG Heng Wei HAN Qin Hua ZHAO Jian Hong ZHANG Xiao Xi | 2013 | Biomedical and Environmental Sciences2013，26，9： | 3 |
