Abstract: 目的:探讨丹参(danshen)、美托洛尔(metoprolol)药物干预对异丙肾上腺素诱导大鼠心缺血坏死区干细胞修复的影响.方法:健康SD大鼠40只,按4mg/kg的剂量连续腹腔注射盐酸异丙肾上腺素(ISO)7 d制备大鼠心肌缺血模型,将造模成功的32只大鼠随机分为4组,异丙肾上腺素对照组(ISO组),丹参干预组(Danshen组),美托洛尔干预组(Meto组),丹参+美托洛尔联合干预组(Danshen+-Meto组).H-E染色比较各组心室肌缺血坏死区大小、免疫荧光观察缺血坏死区c-kit、CD34干细胞标记物及心肌早期转录因子GATA-4和心肌缝隙连接蛋白connexin 43的表达情况.结果:与ISO组比较,其他3组大鼠心肌组织H-E染色心室内膜下缺血面积减小,免疫荧光观察显示缺血区及缺血周边表面标记物c-kit、CD34阳性干细胞增多,缺血区可观察到GATA-4及connexin 43的表达.结论:丹参、美托洛尔能促进心肌缺血坏死区干细胞的迁移和增殖,并最终形成具心肌细胞特征的“心肌样细胞”.
