Network Meta-analysis of 3 kinds of Chinese medicine injections in treatment of acute exacerbations of chronic obstructive pulmonary disease / 中国中药杂志

To evaluate the efficacy and safety of traditional Chinese medicine injections( CMI) in the treatment of acute exacerbation of chronic obstructive pulmonary disease( AECOPD). PubMed,Cochrane Library,CNKI,CBM,Wan Fang and VIP database( since the date of database establishment to July 2018) were retrieved through computer for controlled randomized trials( CRTs) of 3 kinds of traditional Chinese medicine injections( Chuankezhi Injection,Tanreqing Injection,Xuebijing Injection) for AECOPD. After the methodological quality of included researches were evaluated,and the valid data were extracted,statistical analysis was performed with Stata 14,RevMan 5.3 is used for risk bias map. There were including 4 RCTs and 20 quasi-RCTs,which involving 579 patients.The results of network Meta-analysis showed that: ①there were significant differences in the forced expiratory volume in the first second between the 3 CMI and control groups,and there was no significant difference between CMI; ②3 kinds of CMI adjuvant therapy AECOPD,According to the forced expiratory volume in the first second of the probability ranking results,Tanreqing Injection is more effective,followed by Xuebijing Injection and Chuankezhi Injection. Based on the present evidence,3 kinds of CMI can improve the forced expiratory volume in the first second on the basis of Western medicine routine treatment of AECOPD,having better safty. In addition,the conclusion of this study still needs a large number of RCTs with reasonable design and proper method to confirm it.

P-JAK2 and P-STAT3 protein expression and cell apoptosis following focal cerebral ischemia-reperfusion injury in rats / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the changes in phosphorylated JAK2 and STAT3 protein expression of and cell apoptosis following focal cerebral ischemia-reperfusion injury in rats.</p><p><b>METHODS</b>A rat models of focal cerebral ischemia-reperfusion injury was established by middle cerebral artery occlusion using modified filament method. Immunohistochemistry and Western blot analysis were used to detect the expression of P-JAK2 and P-STAT3 proteins, and TUNEL assay was employed to examine the cell apoptosis.</p><p><b>RESULTS</b>P-JAK2 and P-STAT3 protein expression increased significantly after cerebral ischemia-reperfusion injury in rats. The immunoreactivity was prominent in the peripheral of the ischemic region and reached the peak level at 24 h of reperfusion, followed by slight decrement. The apoptotic cells increased obviously after cerebral ischemia-reperfusion injury, also reaching the peak level at 24 h of reperfusion.</p><p><b>CONCLUSION</b>The expression of phosphorylated JAK2 and STAT3 may be involved in the ischemic cellular events including apoptosis. JAK2/STAT3 signaling pathway plays a role in the pathophysiological process of cerebral ischemia/reperfusion cell injury and repair.</p>
