目的,2,验证芪珀生脉颗粒通过调节PI3K/SGK1信号通路改善心房颤动(简称“房颤”)大鼠心房肌纤维化的机制。,方法,2,采用尾静脉注射乙酰胆碱-氯化钙(Ach-CaCl,2,)建立房颤大鼠模型,随机分为正常对照组、模型组、维拉帕米组、芪珀生脉大剂量组、芪珀生脉中剂量组、芪珀生脉小剂量组,共6组。用药干预4周后,比较各组大鼠房颤持续时间、心房肌组织病理改变,运用Western Blot法检测PI3K/SGK1信号通路蛋白的表达水平。,结果,2,与模型组相比,芪珀生脉颗粒各剂量组大鼠房颤持续时间显著缩短,大鼠心房肌PI3K、CTGF蛋白表达明显下调,SGK1蛋白的磷酸化明显减轻,差异有统计学意义(,P,<, 0.05)。,结论,2,芪珀生脉颗粒可有效改善房颤过程中的心房纤维化、缩短房颤持续时间,其机制可能与其调节PI3K/SGK1信号通路,包括下调PI3K、CTGF蛋白的表达,减少SGK1蛋白的磷酸化有关。
