| 摘 要： | 目的探讨同种异体骨髓单个核细胞（BM—MNCs）对急性心肌梗死后心肌细胞凋亡基因的影响。方法健康雄性Wistar大鼠40只，随机分为对照组（20只）和实验组（20只）。分别将培养基和BM—MNCs悬液经心外膜下种植对照组和实验组梗死心肌周围。结果术后4周，实验组左心室非梗死区心肌细胞凋亡指数、TNF-α含量和PDCD5mRNA均显著低于对照组（P均〈0．05）。Pearson直线回归分析表明，两组左心室非梗死区心肌组织中TNF—α含量、心肌细胞凋亡指数和PDCD5mRNA表达三者之间两两均呈正相关（P均〈0．05）。结论BM—MNCs移植可能通过抑制TNF—α表达而降低PDCD5基因促凋亡作用，从而降低心肌细胞凋亡指数，抑制急性心肌梗死后心肌细胞凋亡。 |

| Abstract: | Objective To observe the effect of allogenic bone marrow mononuclear cells(BM-MNCs) transplantation on myocardial apoptosis after acute myocardial infarction(AMI) in rats.Methods 40 Wistar rats were randomly divided into control group(n=20) and transplantation group(n=20).Myocardium around the infarcted left ventricular area of the rats in transplantation group were injected with BM-MNCs suspension beneath the epicardium.Myocardium the area of control group was injected with culture solution.Results After 4... |
