摘要
目的研究组织因子途径抑制物(TFPI)对兔心肌梗死再灌注后无复流的影响,探讨TFPI改善心肌梗死再灌注后无复流的作用机制。方法 30只日本大耳白兔随机分为假手术组、盐水对照组和TFPI组。建立兔急性心肌梗死再灌注后无复流模型。用硫黄素S活体染色,观察兔心肌无复流范围;伊文斯蓝、四氮唑红染色,评估兔心肌缺血及梗死范围。免疫组化法检测心肌组织梗死及周围区组织因子(TF)、白介素6(IL-6)、肿瘤坏死因子α(TNF-α)的表达。结果心肌梗死再灌注后90min,盐水对照组兔IL-6和TF水平明显高于TFPI组和假手术组(P均<0.05)。各组TNF-α的表达无统计学差异(P>0.05)。TFPI组与盐水对照组结扎区心肌范围相似(P>0.05),但无复流范围及坏死心肌范围明显小于盐水对照组(P<0.05,P<0.01)。结论兔心肌梗死缺血60min再灌注90min可发生无复流现象;TFPI可缩小无复流及坏死范围,其机制可能与抑制血栓形成和炎性反应有关。
