摘要 目的:观察缺血后处理对猪心肌缺血再灌注损伤的保护作用及其对炎性细胞因子的影响,并探讨可能的保护机制。方法:滇南小耳猪15只,随机分为假手术组(S组,n=5)、缺血后处理组(IPC组,n=5)和缺血再灌注组(IR组,n=5)。用球囊封堵冠脉建立猪闭胸式心肌梗死动物模型,监测心电及血压,用ELISA法测定缺血前及再灌注2、24h的肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)和白细胞介素10(IL-10)的浓度,再灌注72h采用2,3,5-氯化三苯基四氮唑(TTC)染色确定心肌梗死面积。结果:再灌注2h和24h,IPC组和IR组的TNF-α、IL-6和IL-10的浓度均明显高于缺血前基础值(P<0.05);组间比较,再灌注后IPC组TNF-α和IL-6水平均较IR组明显降低(P<0.05),而IL-10值明显增高(P<0.05)。经TTC染色测心肌梗死的面积,S组未发生心肌梗死,IPC组为(10.89±2.02)%,IR组为(23.26±3.13)%,IPC组的心肌梗死面积较IR组明显降低(P<0.05)。结论:缺血后处理可能通过调控炎性细胞因子平衡发挥心肌保护作用。
