目的测定白细胞介素-8(IL-8)、白细胞介素-6(IL-6)和C反应蛋白(CRP)在慢性阻塞性肺疾病(COPD)平稳期患者血清中的浓度,探讨炎性介质对病程的影响. 方法 26例老年平稳期、病情严重度为Ⅱ级的慢性阻塞性肺疾病患者与31例对照组;采集外周血5ml离心,采用生物芯片技术测定(IL-8)、(IL-6)和散射浊度测定法CRP. 结果慢性阻塞性肺疾病组的IL-8明显高于正常对照组,差异有显著性;IL-6和C-反应蛋白较正常对照组比较差异无显著性. 结论白细胞介素-8在慢性阻塞性肺疾病平稳期的患者中有明显增高,提示它参与了COPD病程的进展,是气道炎症不可逆转的原因之一;白细胞介素-6、C-反应蛋白与对照组比较差异无显著性意义,表明白细胞介素-6、C-反应蛋白在COPD平稳期的病程中可能没有重要意义.
OBJECTIVE To investigate the implication of interleukin-8(IL-8), interleukin-6(IL-6) and C-reactive protein(CRP) in the stable period of elderly patients of chronic obstructive pulmonary disease(COPD). METHODS Twenty six elderly patients in the stable period of COPD ( grade Ⅱ) and 31 normal controls were selected. Levels of IL-8, IL-6 and CRP in serum were detected by bio-chip and nephelometry, respectively. RESULTS The level of serum in COPD patients was higher than control group( P<0.05). And the levels of serum IL-6 and CPR were not significantly high in COPD group than those in control one. CONCLUSIONS In the stable period of COPD, the level of serum IL-8 is increased and it is possible involved the processes of chronic airway inflammation. IL-8 may be one of important cytokines in chronic airway inflammation in COPD. However the levels of serum IL-6 and CRP have no significant difference in COPD group than in control group that means they may not play an important role in the stable period of COPD.
