摘要 将雄性Wistar大鼠50只随机分为移植组及对照1、2、3组。用结扎冠状动脉左前降支的方法建立大鼠急性心肌梗死(AMI)模型。对照1组单纯开胸但不结扎冠状动脉;对照2组仅建立AMI模型;对照3组将培养基经心外膜下植入梗死心肌周围;移植组将制备好的同种异体骨髓单个核细胞(BM-MNCs)悬液经心外膜下植入梗死心肌周围。移植术后4周末,超声心动图及心导管检查评价左室形态及功能,并观察梗死区及其周边区心肌内移植BM-MNCs组织形态学特点。结果与对照1组相比,对照2、3组及移植组左室收缩末期内径(LVEDs)、左室舒张末期内径(LVEDd)和左室舒张末压(LVEDP)均显著升高(P<均0.05),左室射血分数(LVEF)、左室短轴缩短率(LVFS)、左室收缩压(LVSP)、左室压最大上升速率(+dp/dtmax)和左室压最大下降速率(-dp/dtmax)均显著降低(P均<0.05);移植组LVEDs、LVEDd和LVEDP显著低于对照2、3组(P均<0.05),LVEF、LVFS、+dp/dtmax和-dp/dtmax显著高于对照2、3组(P均<0.05);免疫组织化学检查发现移植组AMI区内有存活的BrdU标记阳性的BM-MNCs。证实同种异体大鼠BM-MNCs移植可减轻急性AMI后的左心室扩大,抑制左室重构,改善AMI后的心脏功能。
