Model group,Buyanghuanwu decoction group,G. biloba group were prepared to be intracerebral hemorrhage rat models by referring to Rosenberg law. While the expression of " polarity" of aquaporin AQP4 was detected by immunofluorescence labeling method,the Evans blue( Evans Blue,EB) content of brain tissue was determined by Spectrophotometry. In addition,the water content of brain tissue was detected by wet and dry weight method. [Results] When compared to the model group,the Buyang Huanwu decoction group,G. biloba group of PI3K and AKT proteins expression increased significantly( P < 0. 05) and AQP4 in Astrocyte end feet membrane concentrated expression significantly increased( P < 0. 05),EB content and water content of brain tissue significantly reduced( P <0. 05).[Conclusions]The protective mechanisms of Buyanghuanwu decoction on cerebral hemorrhage can work might because it can activate PI3K/AKT signaling pathway,regulate AQP4 " polar" expression,and reduce the permeability of the blood brain barrier and cerebral edema.展开更多

Methods: CNKI, Wanfang knowledge service platform, VIP journal database, Chinese biomedical literature database (CBM), Pubmed, the Cochrane Library, Science Citation Index (SCI) and Elsevier SD databases were searched from the origin time to May 2018. Cochrane recommended bias risk assessment method was used to evaluate the bias risk. Review Manager 5.3 was used to perform meta-analysis. Results: A total of 12 studies with a 1246 cases were included in the study. The results of the analysis showed that the efficacy of BYHW decoction combined with western medicine treatment was better than that of control group (OR = 2.88, 95% CI (2.10,3.95), P < 0.001)]. The neurological deficit score in the treatment group was lower than that in the control group, and the difference was statistically significant [MD =-2.84, 95% CI (-3.22,-2.45), P < 0.001]. The scores of daily living ability in the treatment group were higher than those in the control group, and the difference was statistically significant [MD = 8.89, 95% CI (7.61, 10.16), P <0.00001]. In the safety aspect, the results of the study are different, and there was a lack of quantitative indicators to evaluate the objectivity of adverse reactions. Conclusion: BYHW decoction combined with the Western medicine is an effective treatment for the recovery period of cerebral infarction, which can significantly improve the clinical efficacy, improve patients' neurological symptoms and their quality of life.展开更多
