摘要
目的 探讨慢性阻塞性肺疾病 (COPD)患者肺通气功能改变与炎症因子变化之间的关系。方法 稳定期COPD和慢性支气管炎 (简称慢支 )患者各 8例 ,,另有 8名健康者作为对照 ,进行肺功能检查 ,并经支气管肺泡灌洗获取肺泡巨噬细胞进行培养 ,采用酶联免疫吸附 (ELISA)方法测定大肠杆菌内毒素 (LPS)刺激后上清液中白细胞介素 8(IL 8)、IL 1β、IL 6和肿瘤坏死因子α(TNF α)的浓度 ,细胞因子之间相关性采用Pearson相关阵分析 ,肺功能值与细胞因子相关性采用多元后退回归法分析。结果  (1)肺泡巨噬细胞释放IL 8:加入LPS后COPD组为 [(43± 2 7) μg/L和 (5 7± 41) μg/L],与正常对照组 [(13± 10 ) μg/L和 (2 0± 13 ) μg/L) ]比较差异有显著性 (P <0 .0 5 ) ;与慢支组 [(2 9± 2 1)μg/L和 (3 2± 2 3 ) μg/L]比较差异有显著性 (P >0 .0 5 )。 (2 )加入LPS前、后 ,COPD组、慢支组和正常对照组肺泡巨噬细胞释放IL 1β分别为 [(5 0± 41)ng/L、(94± 5 9)ng/L、(3 7± 3 2 )ng/L、(2 2 5± 10 8)ng/L、(15 3± 175 )ng/L、(70± 3 7)ng/L],与IL 8的释放呈正相关 (P <0 .0 5 ) ;三组肺泡巨噬细胞在LPS刺激后释放TNF α分别为 [(12 3 8± 679)ng/L、(3 0 88± 2 879)ng/L、(13 3 2± 1846)ng/L],与IL 1β呈正相
