In 2007, the findings from clinical trials on stroke treatment have been both encouraging and disappointing. In order to interpret the challenges and opportunity in evidence-based stroke practice, we reviewed several major clinical trials in stroke that were published last year. It revealed that we should strengthen the evidence base for acute stroke care by conducting more high-quality randomized controlled trials and by increasing the energy, resources and manpower available for these trials.
ObjectiveTo systematically review the effects of aminophylline combined with traditional Chinese medicine (TCM) in the treatment of asthma. MethodsDatabases including The Cochrane Library(Issue 1, 2015), PubMed, EMbase, CNKI, VIP and WanFang Data databases were electronically searched from January 2005 to December 2014 to collect randomized controlled trials (RCTs) about the treatment of bronchial asthma combining aminophylline with TCM. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.3 software. ResultsA total of 10 RCTs involving 820 participants were included. The results of meta-analysis showed that: The total clinical effective rate in the aminophylline plus TCM group was higher than that of the aminophylline alone group (RR=1.22, 95%CI 1.11 to 1.33). The FEV1 in the aminophylline plus TCM group was also higher than that of the aminophylline alone group (MD=0.53, 95%CI 0.33 to 0.73). ConclusionCurrent evidence shows, the total clinical effective rate of aminophylline combined with TCM for asthma is better than that of aminophylline alone, and its mechanism may be related to the improvement of FEV1. Due to the limited quantity and quality of included studies, the above conclusion needs to be further verified by more high quality studies.
