Objective To explore the correlation between the serum levels of interferon (IFN)-γ,interleukin (IL)-18,IL-10 and recurrent spontaneous abortion (RSA).Methods Enzyme-linked immunosorbent assay was used to detect the serum levels of IFN-γ,IL-18 and IL-10.There were 40 patients with RSA (RSA group) and 40 normal early pregnant women (control group) enrolled in this study.After 2 months,those serum cytokines in two groups of non-pregnant state were detected again.Results Compared to control group,the serum levels of IFN-γ and IL-18 of RSA group were significantly higher (P ＜0.01),the serum level of IL-10 was significantly lower (P ＜ 0.01).Two months after termination of pregnancy,there was no significant difference in the serum levels of IFN-γ and IL-10 between the two groups.The serum level of IL-18 maintained a high level in the RSA group after termination of pregnancy.Conclusions In patients with RSA,the serum levels of IFN-γ and IL-18 were elevated,the serum level of IL-10 was decreased.The serum levels of IFN-γ,IL-18 and IL-10 were closely related with RSA.

Objective To investigate the etiological characteristics of diarrhea patients visiting enteric disease clinics in Beijing .Methods A total of 595 stool samples were collected among outpatients with diarrhea vistiting enteric disease clinics at two sentinel hospitals from July 2013 to June 2014 . Diarrheagenic Escherichia coli (E . coli) , Vibrio parahemolyticus , O1 or O139 Vibrio cholerae , Salmonella and Shigella were isolated according to standard methods . And rotavirus , norovirus , astrovirus and enteric adenovirus were identified by molecular techniques .The characteristics of population and temporal distribution , and serotypes of these pathogens were analyzed using descriptive epidemiological method .Chi‐square test was used for comparison between groups .Results Totally 128 bacterial strains were isolated from 595 samples ,and the detection rate was 21 .5% .Diarrheagenic E .coli was most common pathogenic bacteria (11 .4% ,68/595) ,followed by Vibrio parahemolyticus (6 .9% , 41/595) ,Salmonella (2 .4% ,14/595) and Shigella (2 .2% ,13/595) .No V ibrio cholerae was detected . One hundred and twelve viral strains were detected from all samples ,and the positive rate was 18 .8% . Norovirus was most common viral pathogen (9 .1% ,54/595) ,followed by rotavirus (8 .7% ,52/595) , astrovirus (1 .8% , 11/595 ) and enteric adenovirus (0 .7% , 4/595) . Enteropathogenic E .coli , enterotoxigenic E .coli and enteroadhesive E .coli were the most common types of diarrheagenic E .coli . The most common serotype of Vibrio parahaemolyticus was O4∶K8 .The detection rate of bacterial pathogens reached the peak from June to September ,while the highest detection rate of viral pathogens was found from November to the next March .Conclusion Norovirus and rotavirus are also the main pathogens of the diarnhea patients visiting enteric clinics ,which should be paid enough attention .

Objective To compare the bacteriostasis effect of two disinfectants on frequently touched object sur-faces in laminar flow general intensive care unit (GICU),and investigate bacterial contamination on the object sur-faces,so as to provide reference for proper disinfection method and control of infection.Methods Specimens from surfaces of bed rails and bedside tables were taken for bacterial culture before being disinfected.Then object sur-faces around bed units were disinfected with disinfectant containing 500 mg/L of available chloride (routing group) and GammaTM disinfecting wet wipes (control group)respectively,bacteriostasis rate and qualified rate of bacterial count on object surfaces between two kinds of disinfection methods were compared.Results Before routine disinfec-tion,a total of 87 pathogens were isolated from 200 specimens of object surfaces,bacterial contamination rate was 43.50%. Detection rate of gram-positive bacteria was 78.16%% (n =68),the major were Corynebacterium (26.47%,n = 18), Staphylococcus aureus (23.53%,n=16)and Staphylococcus epidermidis (23.53%,n=16);detection rate of gram-nega-tive bacteria was 21.84%(n=19),the major was Acinetobacter baumannii (63.16%,n=12).After a 10-minute disinfec-tion on surfaces,bacteriostasis rate of routine group and control group was (94.89±7.72)% and(96.33 ±12.88)% re-spectively,there was no significant difference between two groups(P >0.05);qualified rates of bacterial count of object surfaces of two groups were both 100%.Conclusion Regular disinfection of object surfaces around bed units,stand-ardization of the manipulation and hand hygiene compliance of medical personnels are simple and effective method of cutting off bacteria dissemination and preventing healthcare-associated infection.

Objective: To explore the influence of metabolic syndrome on the risks of cardiovascular disease (CVD) events and all-cause mortality. Methods: In this prospective cohort study, urban residents aged 40-79 years in Guiyang were followed-up for three years. The end-points were CVD events and all-cause mortality. COX proportional hazards model were used for the corresponding hazard ratios (HRs) of CVD events and all-cause mortality. Metabolic syndrome was defined according to the 2005 International Diabetes Federation (IDF) criteria. Results: A total of 7 313 subjects were included. 146 cases of CVD events and 80 cases of all-cause mortality were recorded. After adjusting for gender, age, smoking, alcohol consumption, and blood lipid levels, the metabolic syndrome increased the risks of CVD events and all-cause mortality. The HRs were 1.43 (P=0.037) and 1.25 (P=0.418), respectively. As compared metabolic syndrome with non-metabolic syndrome, an increased risk of CVD events was found. The HR was 1.43 (P=0.013). No significantly increased risk of all-cause mortality was found in subjects with metabolic syndrome. Conclusion The metabolic syndrome was associated with increased risk of CVD events and there was no significant increase in all-cause mortality. Metabolic syndrome is an important risk factor for CVD events.

Objective To evaluate the association between site polymorphism of glutathione S-transferase omega1 (GSTO1) gene (rs4925),arsenic (+3) methyhransferase (As3MT) gene (rs11191439) and susceptibility to endemic arsenic poisoning.Methods All related studies in published papers up to March 1,2018 on association between site polymorphism of As3MT gene,GSTO1 gene and susceptibility to endemic arsenic poisoning were collected by searching PubMed,Embase,CNKI,Wanfang and VIP database.The data were screened according to the inclusion and exclusion criteria,and extracted,the quality of included studies was evaluated.The pooled odds ratios (OR) with 95％ confidence intervals (95％CI) were calculated using Review Manager 5.3 software.Publication bias and sensitivity analysis were also assessed.Results A total of 7 case-control studies involving 989 cases and 1 212 controls were included in the Meta-analysis.Individuals carrying at least one allele A at the rs4925 locus of the GSTO1 gene might increase the risk of susceptibility to arsenic poisoning compared with individuals carrying wild homozygous type [AA + CA vs CC,OR (95％CI) =1.37 (1.13,1.65),P ＜ 0.01].There was no statistically significant relationship between susceptibility to arsenic poisoning in individuals with at least one allele C at the rs1 1191439 locus of the As3MT gene compared with individuals carrying wild homozygous type [CC + TC vs TT,OR (95％CI) =1.12 (0.69,1.81),P ＞ 0.05].Conclusions GSTO1 gene rs4925 polymorphism is significantly associated with susceptibility to arsenic poisoning,and the A allele is a risk gene for susceptibility to arsenic poisoning.The As3MT gene rs1 1191439 locus polymorphism is not associated with susceptibility to arsenic poisoning.
