摘要 目的探讨Tei指数、caspase-3 mRNA及bcl-2 mRNA表达与心肌缺血再灌注(IR)损伤的关系。方法将新西兰大耳白兔16只随机均分为假手术组和IR组。IR 180 min后,检测其左心室Tei指数及心功能指标;并用原位末端标记法检测心肌细胞凋亡灰度,半定量RT-PCR法检测caspase-3 mRNA、bcl-2 mRNA表达。结果与假手术组比较,IR组Tei指数升高,左室射血分数降低,细胞凋亡灰度值、caspase-3 mRNA表达升高,bcl-2 mRNA表达降低(P均<0.05)。结论 Tei指数、caspase-3 mRNA、bcl-2 mRNA与心肌细胞凋亡的相关性良好,可作为判定心肌IR损伤的有效指标。
