呼吸康复对慢性阻塞性肺疾病患者血清炎症因子的影响

Effect of pulmonary rehabilitation on inflammatory factors in serum of chronic obstructive pulmonary disease

目的 观察呼吸康复对稳定期慢性阻塞性肺疾病(COPD)患者低度系统炎症相关炎症因子的下调作用.方法 将本院呼吸科47例稳定期慢性阻塞性肺疾病患者随机分为COPD对照组(23例)和COPD呼吸康复组(24例),同时选取本院内科体检的20名健康对照者.COPD对照组和COPD呼吸康复组分别用常规治疗和常规治疗辅以24周的呼吸康复后,比较两组的肺功能指标、健康相关生存质量(HRQoF)以及血气分析.免疫比浊法检测COPD两组治疗前后以及健康对照组的血清C-反应蛋白(CRP),酶联免疫吸附试验(ELISA)检测血清白细胞介素-6(IL-6)和肿瘤坏死因子-α(TNF-α),并比较健康对照组和COPD两组的炎症因子.结果 治疗后COPD呼吸康复组的肺功能、HRQoF以及血气分析均较COPD对照组好转(P<0.05). COPD两组患者在治疗前后血清CRP、IL-6、TNF-α水平均比健康对照组高(P<0.05),治疗后COPD呼吸康复组的CRP[(16.4±3.1)mg/L]比治疗前[(14.6±2.9)mg/L]下降(P=0.048),其他均无明显变化(P>0.05).结论 呼吸康复有助于稳定期COPD患者呼吸功能的恢复,但对低度系统炎症相关因子的影响还不完全明确.

Objective To explore the value of pulmonary rehabilitation contributed to down-regulate the serum C-reactive protein (CRP),interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) in chronic obstructive pulmonary(COPD). Methods Forty-seven patients with stable COPD and 20 age-and sex-matched health subjects with normal pulmonary function were admitted to the study.Forty-seven patients were randomly divided into the COPD control group(n=23) treated on regular therapy and the COPD intervention group (n=24) treated on both regular one and pulmonary rehabilitation, for 24 weeks. pulmonary function, Health-related quality of life(HRQoF) and blood gas analysis were compared between the COPD control group and the COPD intervention group then. Whilst Serum CRP level was measured with the immune-turbidimetric method, while IL-6 and TNF-α concentrations were measured with ELISA among the health and the two COPD patients.Results The COPD intervention group showed better therapy in pulmonary function, HRQoF and blood gas analysis than the COPD control group(P<0.05). Serum CRP, IL-6 and TNF-α were significantly higher before and after treatment in two COPD groups than in control subjects(P<0.05). Serum CRP was down- regulated [(16.4±3.1)mg/L vs (14.6±2.9)mg/L, P=0.048]in the COPD intervention group after therapy than that in COPD control group, but there was no significant different change for IL-6 and TNF-α(P>0.05). Conclusions Pulmonary rehabilitation may have beneficial effects on pulmonary function in stable COPD patients,but still indefinite effect on inflammatory markers in low-grade systemic inflammation.
