[Investigation into the serum uric acid level of the residents in Henglan town of Zhongshan city].

OBJECTIVE: To investigate the relationship between cardiac Cerebrovascular disease and serum uric acid(SUA) in the coastal inhabitant, and try to provide base for prevention of the local metabolic disease and cardiac Cerebrovascular disease. METHOD: We got 3111 local people who had participated in the annual physical examination in the perch hospital for the research on the level of SUA and the relative risk factor. According to SUA level we divided the cases into two groups. One is hyperuricemia group and the other is control group. RESULTS: (1)The average SUA level was (380.2-/+62.58) micromol/L in the males, while (290.82-/+60.32) micromlo/L in the female. The sick rate of hyperuricaemia rate, was 21.8% for male, and the 17.6% of female. This disease affected more men than women. It has significant difference (P<0.01); (2)The SUA level of the showed a positive correlation with the indexes of the total cholesterol, the triglyceride, the blood pressure and the body weight index. The SUA level in overweight/obesity people was obviously higher than that of the normal weight people. CONCLUSIONS: (1)The sick rate of hyperuricaemia is high in Zhongshan coastal area, which due to many related factors. As far as, few people know it, so we should adopt the synthesis measure to prevent and control it to reduce the sick rate; (2)the rise of The SUA level possibly becomes one of the independent dangerous and predictive factor for the heart cerebral von disease.

[Emergence of 16S rRNA methylase gene rmtB in Klebsiella pneumoniae isolates from the inpatients in Zhejiang Province, China].

OBJECTIVE: To investigate the presence and genetic background of 16S rRNA methylase gene and Aminoglycoside modifying enzymes (AMEs) genes in Klebsiella pneumoniae isolated from the People's Liberation Army 98th Hospital, Huzhou district, Zhejiang province, China. METHODS: 25 strains of Klebsiella pneumoniae were isolated from the inpatients between September, 2005 and April, 2006. 6 kinds of 16S rRNA methylase gene (including armA, rmtA, rmtB, rmtC, rmtD and npmA), 6 kinds of AMEs genes [including aac (3)-I, aac (3)-II, aac (6')-I, aac (6')-II, ant (3")-I and ant (2")-I], intI1, intI2, intI3, mercuric reductase gene merA (merA gene were the collective genetic markers of transposons of Tn21 and Tn501) and tnpA (tnpA gene were the collective genetic markers of transposons of Tn1, Tn2,Tn3 and Tn1000) were analyzed by PCR and verificated by DNA sequencing. RESULTS: In 25 strains of Klebsiella pneumoniae, the positive rate of genes of rmtB, aac (3)-II, aac (6')-I, ant (3")-I and intI1 were 60.0% (15/25), 4.0% (1/25), 48.0% (12/25), 60.0% (15/25) and 96.0% (24/25), respectively. The rest 12 kinds of genes were all tested negative. The total positive rate of 6 kinds of AMEs gene was 84.0% (21/25). CONCLUSION: There were very high positive rate on both genes of rmtB and AMEs genotypes in Klebsiella pneumoniae isolated from inpatients, and this was the first report of the emergence of 16S rRNA methylase gene rmtB in Klebsiella pneumoniae identified in Zhejiang province, China.
