Objective To study the influence of bFGF gene transfected bone marrow-derived mesenchymal stem cells (BMSCs) on the inflammatory cytokines of COPD rat. Methods The BMSCs were separated from SD rat and cultured and then bFGF gene was imported to BMSCs by liposome transfection method. The samples were prepared into six groups: normal control group, COPD group (A), BMSCs group (B), pcDNA3.1-BMSCs group (C), bFGF-pcDNA3.1-BMSCs group (D), and bFGF group (E). The expressions of TNF-α and IL-1β by QRT-PCR were detected. Results Compared with COPD group, TNF-α and IL-1β genes from groups B to D dropped significantly (P < 0.05). The changes of TNF-α and IL-1β genes among groups B to D showed no significant difference (P > 0.05). Conclusion BFGF transfected BMSCs, sample BMSCs and pcDNA3.1 transfected BMSCs can inhibit the expression of inflammatory cytokines of TNF-α and IL-1β, but there is no obvious advantage in comparison to bFGF transfected BMSCs and sample BMSCs in respect of inhibiting the expression of inflammatory cytokines of TNF-α and IL-1β.

Objective: To study the protective effect of baicalin on myocardial ischemia reperfusion injury and its correlation to myocardial cell autophagy in experimental rats. Methods: The animal models were established by intragastric infusion at 7 days prior operation in different groups.Atotal of 48 rats were divided into 4 groups: Sham operation group, Sham+baicalin group, Ischemia reperfusion (IR) group and Baicalin treatment group. n=12 in each group. Hemodynamics at different time points and myocardial infarction (MI) size at 45 min after reperfusion were recorded; protein expressions of LC3-II and autophagy-related Becl-1 at 30 min after reperfusion were examined by Westernblot analysis; the opening condition of mitochondrial membrane channel transition pore (mPTP) was detected by NAD+ content. Results: The MI sizes in Sham operation group and Sham+baicalin group were too small to compare; MI sizes in IR group and Baicalin treatment group were (41.32±1.85) % vs (23.30±1.60) %, P<0.001. Protein expressions of LC3-II in IR group and Baicalin treatment group were (1.051±0.005) and (0.863±0.009) which were both higher than Sham operation group (0.763±0.007), P<0.01;Becl-1 were (1.169±0.002) and (0.943±0.005) which were both higher than Sham operation group (0.647±0.014),P<0.01; LC3-II and in Becl-1 expressions in Baicalin treatment group were decreased than IR group, P<0.01. NAD+ contents (by nmol/mg) in IR group and Baicalin treatment group were (6.02±0.33) and (9.56±0.53) which were both lower than Sham operation group (11.28±0.37), P<0.001; NAD+ content in Baicalin treatment group was increased than IR group,P<0.01. Conclusion: Baicalin had no autophagy effect in normal myocardial cells, but it may decrease the MI size and reduce excessive autophagy in myocardial cells after IR which might be related to inhibiting mPTP opening.

10.Efficacy of ultra-early endovascular embolization for ruptured intracranial aneurysms:a Meta-analysis
Chinese Journal of Cerebrovascular Diseases 2017;14(2):64-70
Objective To compare the effectiveness and safety of ultra-early (< 24 h)and delayed (≥ 24 h ) endovascular embolization of ruptured intracranial aneurysms with systematic review. Methods PubMed,Embase,the Cochrane Library,VIP,Wanfang Data,and China National Knowledge Internet (CNKI)were retrieved according to inclusion,exclusion criteria and retrieval strategies,and the clinical literature of ultra-early and delayed endovascular embolization for the treatment of ruptured intracranial aneurysms were obtained. The Review Manager 5. 3 software was used to conduct Meta-analysis for good prognosis rate,postoperative mortality,and postoperative rebleeding rate. Results A total of 10 articles were included,9 of them were retrospective control studies and 1 was prospective control study. A total of 2 021 patients were enrolled,including 970 patients treated with ultra-early treatment;1 051 patients treated with delayed treatment. There was significant difference in the good prognosis rate (OR,2. 67,95% CI 2. 07 -3. 44,P < 0. 01)and the postoperative rebleeding rate (OR,0. 23,95% CI 0. 11 -0. 47)between the ultra - early embolization group and the delayed embolization group (all P < 0. 01). There were no significant difference in the mortality between the two groups (OR,0. 76,95% CI 0. 51 -1. 13,P = 0. 17). The subgroup analysis showed that there were significant differences in the good prognosis rate in the ultra-early group compared with the early group (< 3 d,OR,1. 98,95% CI 1. 33 -2. 95)and the middle and late group (≥3 d,OR,4. 66,95% CI 2. 21 -9. 81,all P < 0. 01). Conclusion Compared with the delayed group, ultra-early embolization of ruptured intracranial aneurysms may improve the good prognosis rate,reduce the rebleeding rate,and not increase the mortality after procedure at the same time. However,more high quality and large sample randomized controlled trials are needed to confirm them.
