We therefore investigated the associations between serum potassium and sodium and risk of incident hypertension in a Chinese community-based population. Methods A total of 839 normotensive individuals without cardiovascular disease from the Chinese Multi-Provincial Cohort Study who took part in the baseline examination in 2007-2008 and the follow-up survey in 2012-2013 were included in this study. Odds ratios （OR） and 95% confidence intervals （95%CI） for baseline serum potassium and sodium in relation to the risk of new-onset hypertension were evaluated using multivari- ate logistic regression models. Results During five years of follow-up, 218 （26.0%） individuals progressed to hypertension. Logistic re- gression adjusting for multiple confounders showed that every 1 mEq/L increment in baseline serum potassium level was associated with a 75% increased risk of hypertension （OR： 1.75; 95%CI： 1.01-3.04; P = 0.04）. Compared with adults with serum potassium level of 4.20-4.79 mEq/L, adults with level 〉 4.80 mEq/L had an 84% increased risk of hypertension （OR： 1.84; 95%CI： 1.14-2.96; P = 0.01）. There was no significant association between serum sodium and risk of hypertension （OR： 0.96; 95%CI： 0.89-1.04; P = 0.33）. Conclusions Base- line serum potassium level, but not baseline serum sodium level, was positively related to the risk of incident hypertension in the Chinese population.展开更多

The aim of this study is to evaluate prediction value of cancer on repeat biopsy in patients with high-grade prostatic intraepithelial neoplasia, using multivariate analysis. Methods: Thirty-eight men with a diagnosis of isolated high-grade prostatic intraepithelial neo-plasia in initial needle biopsy were studies, in the Fist Affiliated Hospital of Medical School of Xi'an Jiaotong University, from January 2003 to March 2009. These samples were using immunostaining of p63 and 34βE12 and P504s, with a median fol-low-up of 525 (range, 7 to 1650) days, and to researched the incidence of subsequent prostate cancer, and to predicted the risk of prostate cancer in clinicopathological parameters of isolated high-grade prostatic intraepithelial neoplasia on repeat biopsies by logistic regression analysis. Results: There were 10 of 38 (26.3%) men with prostate cancer on repeat biopsies after diagnosis isolated high-grade prostatic intraepithelial neoplasia in initial biopsy, of the rates of prostate cancer were 80% for micropapillary and 75% for cribriform high-grade prostatic intraepithelial neoplasia (P < 0.05), respectively. The positive cores of isolated high-grade prostatic intraepithelial neoplasia was the important for the risk of prostate cancer using Multi-factor logistic regression analysis. The time range in 30 to 690 days was stronger risk for prostate cancer detection after diagnosis isolated HGPIN in initial biopsy. p63 and 34βE12 were disrupted positive expression, and P504S was weak posi-tive expression in the 61% isolated high-grade prostatic intraepithelial neoplasia. Conclusion: Isolated high-grade prostatic intraepithelial neoplasia on repeat biopsy conferred a 26.3% risk of prostate cancer, and this risk level is lower than the previ-ously reported risk of 24% to 58%. The number of positive cores and the histopathological pattern with high-grade prostatic intraepithelial neoplasia on initial biopsy was significantly associated with the risk of cancer.展开更多
