摘要
目的探讨过敏毒素C3a及白细胞介素-32(IL-32)在慢性阻塞性肺疾病(COPD)气道炎症中的作用。方法纳入COPD稳定期患者30例,COPD急性加重期(AECOPD)患者30例,健康对照者10例。收集受试者痰液及静脉血,应用实时荧光定量逆转录-聚合酶链式反应(RT-PCR)检测痰细胞裂解液及静脉血细胞裂解液中C3和IL-32 mRNA的表达,应用酶联免疫吸附试验(ELISA)检测痰上清液及静脉血清中C3a和IL-32蛋白的表达,分析C3a与IL-32、IL-32与COPD患者肺功能损伤的相关性。结果 AECOPD患者痰细胞裂解液及静脉血细胞裂解液中C3和IL-32 mRNA水平显著升高,痰上清液及静脉血清中C3a和IL-32蛋白水平显著升高。AECOPD患者静脉血清中IL-32蛋白浓度与C3a蛋白浓度呈显著正相关,IL-32蛋白浓度与1 s用力呼气容积(FEV1)占预计值百分比(FEV1%预计值)及FEV1/用力肺活量(FVC)呈显著负相关。结论 C3a通过诱导IL-32促进COPD气道炎症,加重肺功能损害,这将为COPD的诊断和治疗提供有效的靶位。
