Abstract
目的 探讨脓毒症继发急性肺损伤患者肺组织髓过氧化物酶(myeloperoxidase,MPO)和超氧化物歧化酶(superoxide dismutase,SOD)活性、细胞间黏附分子-1(intercellular adhesion molecule-1,ICAM-1)和血管细胞黏附分子-1(vascular cell adhesion molecule-1,VCAM-1)表达及血清肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)和核因子-κB(nuclcar factor-κB,NF-κB)水平变化及临床意义.方法 60例脓毒症患者,根据脓毒症3.0标准分为2组,30例单纯脓毒症患者为脓毒症组,30例脓毒症继发急性肺损伤患者为急性肺损伤组.采用比色法检测患者肺组织MPO和SOD活性,采用免疫组织化学法检测肺组织ICAM-1和VCAM-1表达,采用ELISA法检测血清TNF-α水平,采用单克隆抗体法检测血清NF-κB水平,并进行2组间比较.结果 急性肺损伤组肺组织MPO活性[(29.21±4.28)u/g]高于脓毒症组[(21.11±3.55) u/g] (P<0.05),SOD活性[(101.18±14.18)u/mg prot)]低于脓毒症组[(165.83±15.08)u/mg prot](P<0.05);急性肺损伤组肺组织ICAM-1[(37.93±4.05)个/视野]和VCAM-1[(33.07±4.18)个/视野]表达高于脓毒症组[(25.83±3.39)、(17.22±3.08)个/视野](P<0.05);急性肺损伤组血清TNF-α[(407.21±41.28)pg/L]、NF-κB[(34.22±3.26)mg/L]水平高于脓毒症组[(218.11±29.55) pg/L、(16.07±2.03) mg/L] (P<0.05).结论 血清TNF-α、NF-κB,肺组织MPO活性和ICAM-1、VCAM-1表达水平增高、SOD活性降低提示有可能发生脓毒症继发急性肺损伤.
