摘要
目的 探讨 3种细胞因子和炎症细胞在慢性阻塞性肺疾病 (COPD)发病机制中的作用。方法 收集 2 0例稳定期COPD患者、10名健康吸烟者 (HS)和 10名健康不吸烟者 (HNS)的痰液。对痰液进行炎症细胞计数与分类检查 ,并用放射免疫法测定痰液中白细胞介素 8(IL 8)、白细胞介素 6(IL 6 )与肿瘤坏死因子α(TNF α)水平。结果 COPD组痰液IL 8、TNF α水平及中性粒细胞分类 (PMN)明显高于HS组和HNS组 (P <0 0 1)。HS组痰液IL 8水平及PMN明显高于HNS组 (P <0 0 5 )。痰液IL 6水平在 3组之间差异无显著性 (P >0 0 5 )。COPD组痰液IL 8水平与TNF α水平及PNM呈显著正相关 (r′s=0 5 999、0 6 737) ,HS组痰液IL 8水平与PMN也呈显著正相关 (rs=0 842 4)。在COPD组 ,痰液IL 8、TNF α水平及PMN与一秒钟用力呼气容积占预计值百分比 (FEV1占预计值 % )、一秒钟用力呼气容积 /用力肺活量 (FEV1/FVC)呈显著负相关 (r′s=- 0 6 45 3、- 0 734 1、- 0 734 1、- 0 76 2 4、- 0 5 2 6 2、- 0 735 3)。结论 IL 8、TNF α和中性粒细胞共同参与了COPD气道炎症反应并导致气流阻塞的形成。
