Abstract： 目的:本实验通过对冠心病急性心肌梗死(AMI)患者及AMI溶栓治疗前后白细胞介素8(IL-8)变化的研究,为AMI的早期诊断及溶栓治疗提供可供参考的依据.方法:AMI患者,依据治疗情况分为:(1)溶栓组,于溶栓即刻、溶栓后2、4、6、8、10、12h测定血清中IL-8浓度,并依据溶栓结果分为:溶栓再通组(A组)、溶栓未通组(B组).(2)未溶栓组,于症状出现后2、4、6、8、10、12、14h测定血清中IL-8浓度.IL-8浓度应用酶联免疫吸附(ELISA)法测定.同时测定血清心肌酶CK-MB的浓度.结果:(1)IL-8在AMI患者症状出现后4.47±1.50h升高,水平明显高于正常对照组,时间早于CK-MB升高的时间(P＜0.01),并可在9.69±3.54h时达到高峰;(2)A组IL-8浓度在溶栓后4、6、8h显著高于B组(P＜0.01、P＜0.01、P＜0.05),B组IL-8浓度与未溶栓组之间无显著区别.(3)正常对照组IL-8浓度＜10pg/ml.结论:(1)AMI患者血清中很早即可测得IL-8浓度,水平明显高于正常对照组,时间早于CK-MB升高的时间,故认为IL-8可作为AMI早期诊断的参考指标之一;(2)溶栓再通组可于溶栓后4、6、8h检测到明显升高的IL-8浓度,故认为IL-8可以作为判定AMI溶栓治疗是否再通的指标之一.
