摘要
目的 :比较脓毒症时肝脏与肺脏在细胞因子表达上的差异。方法 :盲肠结扎穿孔 (CL P)造成脓毒症小鼠模型 ,假手术组接受同样手术操作但不行 CL P。用逆转录聚合酶链反应 (RT PCR)的方法检测了脓毒症小鼠肝、肺组织中多种细胞因子〔促炎症细胞因子肿瘤坏死因子α(TNFα)、白介素β(IL 1β)、IL 6 ,抗炎症细胞因子 IL 4〕m RNA的表达。结果 :CL P后 ,肺组织中促炎症细胞因子 TNFα、IL 1β、IL 6的表达明显增高 ,而抗炎症细胞因子 IL 4的表达却无明显改变 ;肝组织中在促炎症细胞因子 TNFα、IL 1β、IL 6表达明显增高的同时 ,抗炎症细胞因子 IL 结论 :脓毒症时肝、肺组织中炎症反应的状况和程度是不同的。其中肝脏在脓毒症早期以促炎症反应占主导地位 ,晚期同时还产生了代偿性的抗炎症反应 ;而肺脏无论在脓毒症早期还是晚期均是以促炎症反应占主导地位
