目的:研究参附汤血中移行成分对血管紧张素Ⅱ(AngⅡ)所致心肌细胞凋亡及自噬的影响. 方法:采用原代培养乳鼠心肌细胞,随机分为空白组、AngⅡ组、移行成分组.运用MTT比色实试验法测定心肌细胞存活率,采用实时定量PCR检测凋亡相关基因Caspase-3和自噬相关基因Beclin1、Atg5mRNA水平在不同组中的表达. 结果:与正常组比较,血中移行成分组细胞存活率无明显变化(P>0.05),与模型组比较血中移行成分组明显能够提高AngⅡ致肥大细胞的存活率(P<0.01);在凋亡及自噬相关基因的表达上与模型组比较,血中移行成分组明显能够降低肥大心肌Caspase-3、Beclin1、Atg5mRNA的表达(P<0.05). 结论:参附汤对AngⅡ所致肥大心肌细胞的凋亡及自噬均有保护作用.
