Objective To investigate whether sulfonylurea ( SU) increases the risk of stroke in patients with type 2 diabetes mellitus(T2DM). Methods A systemic meta-analysis including 17 random control trails(RCT) was performed to compare the risk of stroke between type 2 diabetic patients treated with SUs and comparators. Results 1 612 articles were retrieved, and finally 17 articles were included. Patients receiving SUs treatment had a higher relative risk of stroke (RR 1. 35, 95% CI 1. 13-1. 60) than those who received comparators. The I2 statistic for heterogeneity between 17 trails was 0. 0%(P=0. 687). No major asymmetry appeared in the funnel plot and Begg′adjusted rank correlation test(kendall′s score=22, P=0. 387). Conclusion The use of SUs may raise the risk of stroke which is already high in patients with T2DM.

Objective To investigate effects of total flavonoids of litchi (TFL) on the proliferation of rat hepatic stellate cells (HSC-T6) in comparison with western medicine rosiglitazone, and to explore the mechanism of anti hepatic fibrosis of TFL. Methods Effect of TFL on proliferation of HSC-T6 was examined by MTT. The expression of peroxisome proliferator-activated receptor-γ (PPAR-γ) mRNA, connective tissue growth factor (CTGF) mRNA in HSC-T6 cells exposured were examined by real-time quantitative PCR. Effects on HSC-T6 CTGF protein from TFL and rosiglitazone were detected by Western bloting. Results The expression of PPAR-γ mRNA was upregulated and the expression of CTGF mRNA and protein was downregulated after exposure to TFL and rosiglitazone for 72 hours. And the effect of TFL increased with the increase of concentration. Conclusion TFL can inhibit the proliferation of HSC-T6 and antagonizing liver fibrosis. This mechanism may be associated with the upregulation of PPAR-γ expression and the downregulation of CTGF expression.
