OBJECTIVE: To evaluate systematically the clinical efficacy and safety of Qingkailing(QKL) injection in the treatment of acute ***: Searches for randomized controlled trials into acute stroke treated with QKL injection were performed in the China National Knowledge Infrastructure Database, China Science and Technology Journal Database, Wan fang Database,Chinese Biomedical Literature Database, PubMed and Cochrane Library, from January 1979 to March2013. Two reviewers independently retrieved the RCTs and extracted the information. The Cochrane risk of bias method was used to assess the quality of the included studies, and a Meta-analysis was conducted with Review Manager 5.2 ***: A total of 13 studies with 1110participants were included. The quality of the studies was generally low. The Meta-analysis indicated that the combined use of QKL and Western Medicine was significantly superior to control group therapy in terms of the total effective rate. The relative risk(RR) in the acute cerebral hemorrhage(ACH) sub-group was 1.17 [95%confidence interval(CI)(1.08, 1.26), P=0.0001]. In the acute cerebral infarction(ACI) sub-group, RR was 1.27 [95% CI(1.14, 1.42), P<0.0001], and in the ACH and ACI mixed sub-group, RR was 1.34 [95% CI(1.20,1.50),P<0.00001]. Additionally, QKL promoted the absorption of hematoma [mean difference(MD)=﹣3.73, 95%CI(﹣4.48, ﹣2.98), P<0.000 01],decreased neurological damage in ACI [MD=﹣5.60, 95% CI(﹣8.50, ﹣2.70), P=0.0002] and ACH[MD= ﹣ 4.08, 95% CI( ﹣ 8.00, ﹣ 0.16), P=0.04],promoted the recovery of awareness [RR=1.56, 95%CI(1.09, 2.21), P=0.01] and reduced the whole blood viscosity coefficient [MD=﹣ 0.75, 95% CI( ﹣1.47, ﹣0.03), P=0.04]. There were no adverse drug reactions reported in the included ***: Based on this systematic review,QKL combined with conventional therapy was effective compared with control ***, because the articles used in the study were not of high quality, further studies should

Insights into complex processes of animal development

引用

Journal of Molecular Cell Biology 2014年第4期8卷 271-271页

作者： jiaruiwu Institute of Biochemistry and Cell Biology Shanghai Institutes for Biological Sciences Chinese Academy of Sciences Shanghai 200031 China

Life is very complicated. Recently, a group of review papers on the complexity of various biological behaviors were published by Cell to celebrate its 40th anniversary. The developmental process must be one of the most complex events in multi-cellular organisms. JMCB has published several research papers in the previous Collection 'Understanding and Mani-pulating Developmental Complexity' (Wu, 2013). This issue publishes more articles focusing on the molecular mechanisms that regulate animal developmental processes, which should provide evidences for a better understanding of the developmental complexity.
