摘要
目的观察多发伤病人外周血多形核中性粒细胞(PMNs)ICAM-1、LFA-1表达变化。方法使用流式细胞术分别检测37例多发伤病人入院时、伤后1、3、7天外周静脉血PMNsICAM-1、LFA-1的平均荧光通道(MFC)变化,13例健康志愿者作为对照组。结果多发伤病人PMNsICAM-1、LFA-1表达在创伤后各时相点上与对照组比较有显著差异(P<0.001)。在伤后最初3天内,ISS≥16分组较ISS<16分组明显增高(P<0.01)。在伤后并发MODS、创伤性失血性休克的病人中,PMNsICAM-1、LFA-1表达较非MODS、创伤性失血性休克病人显著增高(P<0.001)。结论严重创伤后细胞粘附分子I-CAM-1,LFA-1的上调表达与损伤严重程度相平行。其动态变化监测对伤情预后的判断可能具有重要的临床意义。
