摘要
目的:探讨间歇运动对心肌梗死(myocardial infarction,MI)大鼠心肌细胞凋亡和心肌白血病抑制因子(Leukemia inhibitory factor,LIF)及其受体LIFR表征的影响。方法:3月龄SD雄性大鼠,随机分为假手术组(Sham)、心梗安静组(MI)、心梗+间歇运动组(ME),每组12只。左冠状动脉前降支(Left anterior descending coronary artery,LAD)结扎建立MI模型,ME组采用小动物跑台进行8周间歇训练。训练结束后次日腹腔麻醉,血流动力学方法评定心功能,Masson染色观察分析心肌胶原容积(Collagen volume fraction,CVF)百分比,TUNEL法检测细胞凋亡,Western Blot检测心肌Bcl-2、Bax、LIF、LIFR、p-STAT 3和STAT 3蛋白表达,RT-qPCR检测心肌lif和lifr mRNA表达。结果:心梗大鼠心功能显著降低,心肌纤维化水平和细胞凋亡显著增加。间歇运动可有效改善心梗大鼠心功能,降低心肌纤维化水平,升高Bcl-2/Bax比值,减少TUNEL阳性颗粒,上调心肌LIF及LIFR蛋白与基因的表达和STAT 3磷酸化水平。结论:间歇运动可显著促进心梗大鼠心肌LIF蛋白表达,激活LIF/LIFR/STAT 3通路,抑制心肌细胞凋亡,改善心梗心脏病理重塑和心功能。开展运动干预缺血心脏LIF表征研究与心脏的保护效应,将为心梗患者运动康复手段筛选提供新思路。
