ABSTRACT
Objective:To investigate the possible role of non-invasive fibrosis scoring systems for detecting high-risk plaque among patients with non-alcoholic fatty liver disease (NAFLD).Methods:A total of 477 consecutive asymptomatic subjects underwent a health checkup including coronary computed tomography angiography (CTA) and abdominal ultrasonography. Fatty liver was evaluated using ultrasonography, and the NAFLD fibrosis score (NFS) was calculated. Coronary stenosis and plaque were evaluated using coronary CTA.Results:Of the study population, 223 had NAFLD. Among the NAFLD patients, high-risk coronary plaque was more frequent in patients with high or intermediate NFS than those with low NFS (62.5% versus 24.0%, P<0.001). The adjusted odds ratio with 95% confidence interval of high-risk plaque was 3.24 (1.11-9.40) for the highest versus lowest quartile of NFS ( P=0.016). Among those without NAFLD, NFS was not associated with high-risk coronary plaque (C-statistic with NFS versus without NFS, 0.766 versus 0.764, P=0.715). Adding NFS to the traditional cardiovascular disease (CVD) risk model increased the C-statistics by 0.679 to 0.739 ( P=0.031). Conclusions:There was an independent association of NFS with high-risk coronary plaque in patients with NAFLD, suggesting its potential use to optimize management of patients with NAFLD.
ABSTRACT
AIM:This study was to investigate the expression and significance of Bmi-1 in colorectal carcinoma (CRC),and to explore the effect of Bmi-1 on Ki67 expression in human CRC.METHODS:The samples from sixty CRC,thirty adenomas and twenty normal colorectal mucosal tissues were used in this study. The expression of Bmi-1 protein was detected by immunohistochemistry. The clinicopathological features and survival rate of patients were also analyzed.RESULTS:The overexpression of Bmi-1 was respectively 25.0%,6.7%and 0% in CRC and adenomas as well as normal colorectal mucosal tissues. The results showed that the expression of Bim-1 was significantly higher in CRC,compared with that in adenomas and normal colorectal mucosal tissues (P0.05). Kaplan-Meier survival analysis showed that the overexpression of Bmi-1 reduced significantly survival of CRC patients (P
