摘要 目的检测急性创伤患者应激早期各时段中性粒细胞中热休克蛋白72(HSP72)的表达水平,并探讨其与患者存活率及预后的关系。方法随机选取收入重症监护治疗病房的急性生理学与慢性健康状况Ⅲ(APACHEⅢ)评分≥18分的患者30例,抽取静脉抗凝血,分离创伤后0~1d,2~6d,7~14d(分别定义为Ⅰ期、Ⅱ期和Ⅲ期)的中性粒细胞,分别应用流式细胞术(FCM)及酶联免疫吸附法(ELISA)检测HSP72表达水平,并记录患者2个月存活率。同时选取10例正常人作为对照。结果急性创伤患者HSP72水平随病程有所变化,Ⅱ期患者HSP72表达水平明显高于Ⅰ期和Ⅲ期患者,且3个时期HSP72水平均高于健康对照组,存活组HSP72水平较死亡组明显增高。结论急性创伤患者在整个观察期间均可检测到HSP72表达,HSP72水平的高峰期出现在创伤后2~6d,存活组HSP72水平较死亡组明显增高,急性创伤后HSP72表达的增强,预示患者存活的可能性大,预后亦较好。
