ABSTRACT: The results of several new clinical trials that compared the effectiveness of entecavir (ETV) treatment with that of adefovir (ADV) treatment in patients with chronic hepatitis B (CHB) were published in recent years. However, the numbers of patients included in these clinical trials were too small to draw a clear conclusion as to whether ETV is more effective than ADV. Therefore, a new meta-analysis was needed to compare ETV with ADV for the treatment of CHB. A search of the Cochrane Central Register of Controlled Trials (CCTR), MEDLINE, the Science Citation Index, Embase, the China National Knowledge Infrastructure (CNKI), and the Wanfang Database for relevant studies published between 1966 and 2010 was performed. Trials comparing the use of ETV and ADV for the treatment of CHB were assessed. Of the 2,358 studies screened, 13 randomized controlled clinical trials comprising 1,230 patients (ETV therapy, 621; ADV therapy, 609) were analyzed. The serum hepatitis B virus (HBV) DNA clearance rate obtained in patients treated with ETV was significantly higher than that in patients treated with ADV at the 24th and 48th weeks of treatment (24 weeks: 59.6% vs. 31.8%, relative risk [RR], 1.82, 95% CI: 1.49-2.23; 48 weeks: 78.3% vs. 50.4%, RR, 1.61, 95% CI: 1.32-1.96). The serum HBeAg clearance rate, the HBeAg seroconversion rate, and the ALT normalization rate obtained for patients treated with ETV were also higher than the corresponding values for patients treated with ADV at the 48th week of treatment. The safety profiles were similar between patients treated with ETV and those treated with ADV. The evidence reviewed in this meta-analysis suggests that patients with hepatitis B have a greater likelihood of achieving a viral response and a biomedical response when treated with ETV than when treated with ADV.

ABSTRACT: To assess whether the TaqIB polymorphism of cholesteryl ester transfer protein (CETP) is associated with coronary artery disease (CAD) in Chinese population, we performed a meta-analysis in this paper.
We searched PubMed, Embase, the Science Citation Index (SCI), the China Biological Medicine database (CBM), the China National Knowledge Infrastructure (CNKI), and the Wanfang database for relevant articles. Data were extracted, and pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated.
The literature search yielded 448 studies, in which 10 case-control studies including 1694 cases and 1456 controls matched the selection criteria. The combined B1 and B2 allele frequencies were 0.587 and 0.413, respectively. The pooled OR was 1.10 (95% CI, 0.89-1.34) for comparing the B1B1 or B1B2 carriers with B2B2 carriers, and was 1.27 (95% CI, 1.09-1.49) in the B1B1 carriers versus B2B2 or B1B2 carriers.
In the present study, the TaqIB polymorphism of CETP was found to be associated with CAD in the Chinese population.

ABSTRACT: Cyclooxygenase-2 (COX-2) and CCAAT/enhancer binding protein β (C/EBPβ) have been shown to be involved in inflammation and carcinogenesis, and our previous study revealed that they were co-overexpressed in human hepatocellular carcinoma (HCC) tissue and a positive correlation was found. Saikosaponin-d (SSD), a triterpene saponin extracted from Bupleurum falcatum L. (Umbelliferae), is known to exert inhibitory effects on COX-2 expression, together with inflammation and hepatic fibrosis. These findings prompted us to investigate the chemopreventive potential of SSD against hepatocarcinogenesis and its possible molecular mechanism in vivo. An experimental model with diethylinitrosamine (DEN)-treated Sprague Dawley rats was used in the present study. DEN (50 mg/kg body weight) and SSD (2 mg/kg body weight) were intraperitoneally injected weekly and daily, respectively. Administration of SSD alone had no side effects. The liver nodule formation, tumorous invasion to surrounding organs and increased cellular atypia induced by DEN were markedly reduced by SSD in the SSD + DEN group compared with the DEN group. On the other hand, immunohistochemical staining demonstrated that the expression of COX-2 and C/EBPβ proteins was significantly increased in tumor cells and macrophages of liver tissue from DEN-treated rats, whereas the expression of the two proteins was markedly lowered in the SSD + DEN group. Overall, our results suggest that SSD prevents DEN-induced hepatocarcinogenesis in rats through inhibition of C/EBPβ and COX-2, providing indispensable experimental evidence for the clinical application of SSD as a novel chemopreventive agent against HCC in the future.

ABSTRACT: To evaluate the therapeutic effect of acupuncture for the aphasia.
The publications of acupuncture for the treatment of aphasia are comprehensively searched from relevant domestic medical literature databases, China National Knowledge Infrastructure and Chinese BioMedical Literature Database. Meta analysis was conducted by using the publications.
Twenty six trials of 338 matched the selection criteria and their data were suitable for Meta analysis. The total aphasia patients were 1749. The total odds ratio (OR) of the improvement with acupuncture plus language training and drugs compared with language training plus drug intervention was 3.66 (95% confidence interval, 2.81, 4.76), and the funnel plot was approximately symmetry. It is indicated that the curative effect of the acupuncture group is better than that of the control group (Z = 9.60, P < 0.001).
The effect of acupuncture with language training plus drugs for the treatment of aphasia is better than that of language training plus drugs only.

ABSTRACT: To study the effects of extract from Ginkgo biloba (EGb) containing 22% flavonoid and 5% terpenoid on chronic liver injury and liver fibrosis of rats induced by carbon tetrachloride (CCl(4)).
All rats were randomly divided into control group, CCl(4)-treated group, colchicine-treated group and EGb-protected group. Chronic liver injury was induced in experimental groups by subcutaneous injection of CCl(4) and fed with chows premixed with 79.5% corn powder, 20% lard and 0.5% cholesterol (v/v). EGb-protected group was treated with EGb (0.5 g/kg body weight per day) for 7 wk. At the end of wk 8, all the rats were killed. Liver function, liver fibrosis, oxidative stress and expression of transforming growth factor beta1 (TGF-beta1), a-smooth muscle actin (alpha-SMA) and type I collagens in liver were determined. In addition, pathology changes of liver tissue were observed under light microscope.
The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and albumin (Alb) in EGb-protected group were notably improved as compared with the CCl(4)-treated group (P < 0.01). The contents of serum hyaluronic acid (HA), type III procollagen (PCIII), type IV collagen (CIV) and the expression of hepatic tissue TGF-beta1, alpha-SMA and type I collagen in EGb-protected group were significantly lower than those in CCl(4)-treated groups (P < 0.05, P < 0.01). The degrees of liver fibrosis in EGb-protected groups were lower than those in CCl(4)-treated groups (6.58 +/- 1.25 vs 9.52 +/- 2.06, P < 0.05). Compared to the CCl(4)-treated group, the levels of plasma glutathoine peroxidase (Se-GSH-Px), superoxide dismutase (SOD) and malondialdehyde (MDA) were strikingly improved also in EGb-protected group (P < 0.05, P < 0.01).
EGb resists oxidative stress and thereby reduces chronic liver injury and liver fibrosis in rats with liver injury induced by CCl(4).
