慢性支气管炎患者支气管肺灌洗液中IL-6分析(英文)

Interleukin-6 in bronchoalveolar lavage fluid from patients with COPD

目的 本研究通过检测支气管肺灌洗液 (BALF)中及肺泡巨噬细胞 (AM)产生的IL 6 ,揭示IL 6与慢性支气管炎(COPD)肺气肿发生的关系 ,为IL 6提供新的研究领域。方法 检测 6名正常无吸烟人及 2 1名COPD患者BALF中及AM释放的IL 6 ,根据正常人组BALF中IL 6的 95 %正常值可信区限 ,将COPD患者分为二组 ,在正常值可信区限内为第一组 ,在正常值可信区限外为第二组。结果 表明 2组中AM产生的IL 6第二组明显高于第一组 ,且 2组患者肺功能 (Dlco ,FEV1,FEV1/FVC和RV/TLC)有明显差异结论 AM产生的IL 6可能与COPD患者肺功能变化有关 。

Objective To obtain new insights into the behavior of Interleukin-6(IL-6)in bronchoalveolar lavage fluid (BALF)and released from alveolar macrophages(AM)in chronic obstructive pulmonary diseases (COPD),and reveal the relationship between IL-6 and the development of emphysema in COPD.Methods IL-6 in BALF and released by AM in BALF were examined in 7 non-smoking subjects and 21 patients with COPD.According to the 95% confidence limits of IL-6 in BALF from non-smoking subjects,the patients were divided into two groups:those who were within the limits were assigned to the first group,and those who were above the limits were assigned to the second group.Results The concentration of IL-6 released by AM was much higher in the second group than in the first one.Between the two groups,significant differences were found in pulmonary function.Conclusion Our results suggest that the concentration of IL-6 released by AM may be related with pulmonary function,and IL-6 may play a role in the development of emphysema in patients with COPD.
