摘要(Abstract)：

目的研究7-二氟亚甲基-5,4'-二甲氧基染料木黄酮(DFMG)对压力性尿失禁(SUI)Wistar大鼠模型肛提肌细胞增殖与凋亡的影响。方法采用模拟产伤及卵巢切除的方法建立SUI Wistar大鼠模型,检测漏尿点压力和腹部漏尿点压力,HE和Masson染色观察肛提肌组织。分离并培养大鼠肛提肌细胞,实验组分为正常对照组、SUI组、SUI+DFMG(2、4、8μmol·L-1)处理组。MTT和FCM分别检测细胞增殖和凋亡;western blot检测c-myc、Fas、caspase-8、bcl-2、bax、cyto-c和caspase-9。结果与对照组比较,SUI组肛提肌细胞增殖率下降,凋亡率升高,bcl-2表达下调,c-myc、Fas、caspase-8、bax、cyto-c、caspase-9表达上调;用DFMG处理SUI大鼠模型肛提肌细胞后,细胞增殖率升高,凋亡率下降,bcl-2表达升高,c-myc、Fas、caspase-8、bax、cyto-c、caspase-9表达减少。结论 DFMG可抑制SUI大鼠模型肛提肌细胞凋亡,促进细胞增殖,其机制可能与其上调bcl-2、下调c-myc、Fas、caspase-8、bax、cyto-c、caspase-9表达有关。
