Interferon plus Chinese herbs are associated with higher sustained virological response than interferon alone in chronic Hepatitis C: a meta-analysis of randomised trials.

BACKGROUND/AIMS: Traditional Chinese herbal therapies are widely used for the treatment of chronic hepatitis C (CHC) in Asia. The aim of this study was to perform a meta-analysis of randomised controlled trials (RCTs) comparing interferon therapies with Chinese herbal therapies and/or interferon plus Chinese herb therapies for the treatment of CHC. METHODS: The Cochrane Central Register of Controlled Trials, Medline, Science Citation Index, EMBASE, China National Knowledge Infrastructure, Wanfang Database and China Biomedical Database were searched to identify RCTs that evaluated the virological response to interferon therapies, Chinese herbal therapies and interferon plus Chinese herb therapies in CHC patients. We statistically combined data using a random-effect meta-analysis according to the intention-to-treat principle. RESULTS: The literature search yielded 770 studies, and 26 RCTs comprising 1905 patients matched the selection criteria. Overall, the sustained virological response (SVR) was significantly higher in patients treated with interferon plus Chinese herbs than in patients treated with interferon alone (49% vs 33%, relative risk, 1.52; 95% confidence interval: 1.23-1.89; p<0.05). Combined therapies of interferon plus Chinese herb therapies were also superior to interferon therapies alone in achieving the end-of-treatment viral response (ETVR), and resulted in fewer relapses, fewer adverse events and more rapid alanine transaminase normalisation. Interferon therapies achieved higher ETVR than Chinese herbal therapies, but they yielded a similar SVR. CONCLUSIONS: The current evidence suggests that combined therapies of interferon plus Chinese herbs yielded a higher SVR, and resulted in fewer relapses and fewer adverse events than interferon therapies.

[Meta analysis on acupuncture treatment of aphasia].

OBJECTIVE: To evaluate the therapeutic effect of acupuncture for the aphasia. METHODS: 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. RESULTS: 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). CONCLUSION: The effect of acupuncture with language training plus drugs for the treatment of aphasia is better than that of language training plus drugs only.
