摘要: 目的 探讨慢性阻塞性肺疾病(COPD)稳定期患者血清α1-抗胰蛋白酶(α1-AT)质量浓度与气道炎症及肺功能的相关性.方法 入选60例稳定期COPD患者及30例健康对照者,检测了入选对象的血清α1-AT、白介素-6(IL-6)、白介素-8(IL-8)、中性粒细胞弹性蛋白酶(NE)水平,并对60例COPD患者进行了肺功能检测.结果 COPD患者血清α1-AT、IL-6、IL-8、NE水平均明显高于对照组,α1-AT质量浓度与NE水平正相关;COPD患者血清α1-AT质量浓度与肺功能残气量/肺总量(RV/TLC)明显负相关.结论 稳定期COPD患者慢性气道炎症持续存在,血清α1-AT质量浓度与气道炎症程度正相关,与肺气肿程度负相关.

Abstract: Objective To investigate the co-relations between serum α1-antitrypsin level and airway inflammation,and pulmonary function in stable COPD patients.Methods 60 stable COPD patients and 30 healthy controls were recruited.Their serums level of α1-antitrypsin,interleukin-6,interleukin-8 and neutrophil elastase,and the patients pulmonary function as well were detected.Results The findings show that the serum levels of α1-AT,IL-6,IL-8 and NE in COPD patients are much higher than those of the controls;there exist positive correlations between serum levels of α1-AT and NE and negative correlations between serum level of α1-AT and RV/TLC of pulmonary function.Conclusion This indicates that airway inflammation continues during the stationary phases in COPD patients,that the serum α1-AT level are positive with the degree of airway inflammation,and negative with the degree of emphysema.

Key words: chronic obstructive pulmonary diseases, α1-antitrypsin, neutrophil elastase, pulmonary function
