ABSTRACT
Objective To analyze the serotype distribution and antibiotic resistance characteristics of food-borne Salmonella strains isolated from food and patients with gastroenteritis in Guizhou Province from 2016 to 2018. Methods Serotypes of the strains were characterised using slid agglutination method with Salmonella antisera. Minimal inhibitory concentrations (MIC) of antibiotics were determined by the broth microdilution method. Microsoft Excel 2007 and SPSS18. 0 were used for statistical analysis. Results A to-tal of 170 strains of food-borne Salmonella were detected in food and patients with gastroenteritis in Guizhou Province from 2016 to 2018. Thirty-five serotypes were identified and 6 were found in both food and pa-tients. The main serotypes in food were Salmonella Typhimurium ( 16. 67％ ) and Salmonella Stanley (8. 33％ ), and the predominant serotypes in patients were Salmonella Typhimurium (41. 79％ ), Salmonel-la Enteritidis (16. 42％ ) and Salmonella London (8. 96％ ). The rate of resistance to ampicillin, chloram-phenicol, tetracycline, ciprofloxacin, nalidixic and trimeth-sulfame were 27. 78％ -33. 33％ among the iso-lates from food, and 22. 22％ -25. 00％ to gentamicin, cefocime and ampicillin/ sulbatan. Among the isolates from patients, the highest resistance was to ampicillin ( 55. 97％ ), followed by that to tetracycline (49. 25％ ), ampicillin/ sulbatan (44. 03％ ), nalidixic acid (41. 04％ ) and cefazolin (37. 31％ ), and 20. 90％ -30. 60％ strains were resistant to chloramphenicol, ciprofloxacin, gentamicin, cefotaxime and am-picillin/ sulbatan. There were 25. 00％ isolates from food and 25. 37％ isolates from patients resistant to at least 6 antibiotics, and the main multi-resistant pattern was ampicillin-tetracyline-nalidixic-cephalosporin an-tibiotics (partial). Conclusions There were many kinds of serotypes of food-borne Salmonella in Guizhou Province from 2016 to 2018 and the predominant types were Salmonella Typhimurium, Salmonella Enteritidis and Salmonella London. Drug resistance was common in the strars and some multidrug resistant strains were detected.

ABSTRACT
Objective To evaluate the relationship between hypertension and triglyceride(TG)increase.Methods Among the population aged 20 to 69 years old who joined the healthy physical examination,170412 persons,who had no disease history of diahetes mellitus(DM)and nephropathy and is not the clear hypertension family history,first accord- ing to whether possibly is accompanied by high hody mass index(BMI),total cholesterol(TC)and/ or glucose (Glu)increase divides into two great groups,were second chosen anti divided into groups with age and the levels of ser- um TG.Then counted the numbers of normal people and hypertension ones in every groups.Results 1.In possible accompanied high BMI,total cholesterol(TC)and/or glucose(Glu)increase group,the overall detection rate of hy- pertension and TG increate has a remarkable correlation(P
