摘要 目的探讨人心房利钠肽(h ANP)对小鼠机械通气所致肺损伤(VILI)时炎症反应的影响。方法将30只雄性C57 B/6小鼠随机分为空白对照组(C组)、机械通气肺损伤组(MV组)和人心房利钠肽组(MV+h ANP组)。MV+h ANP组腹腔注射h ANP 2μg/kg后行机械通气,通气3 h后取材,处死小鼠。采用流式多重蛋白定量技术(CBA)测定小鼠血浆中炎性细胞因子浓度;分离左肺,计算肺组织湿干比值。结果与C组相比,MV组、HV+h ANP组血浆中巨噬细胞炎性蛋白-1[(461.7±91.97)、(348.0±74.40)pg/ml]、肿瘤坏死因子-α[(59.10±7.94)、(48.40±8.34)pg/ml]和白细胞介素-6[(701.7±88.13)、(607.9±61.67)pg/ml]含量明显上升(P<0.05),肺组织W/D值[(4.74±0.84)、(4.61±0.721)]明显升高(P<0.05);与MV组相比,HV+h ANP组血浆中巨噬细胞炎性蛋白-1、肿瘤坏死因子-α、白细胞介素-6明显降低(P<0.05),肺组织W/D降低(P<0.05)。结论人心房钠尿肽能够减轻机械通气所导致的炎症反应,从而减轻肺损伤。
