摘要
目的探讨血浆5-羟色胺(5-TH)与慢性阻塞性肺疾病(COPD)的关系。方法选择COPD患者65例,对照组为同期中老年健康体检者60例,所有研究对象进行常规肺功能测定,采用酶联免疫吸附试验法(ELISA)测定COPD组(包括急性发作期和稳定期)和对照组血浆5HT浓度。结果COPD组(急性加重期、稳定期)血浆5-HT水平较健康对照组显著升高(P〈0.01),而COPD急性加重期较稳定期,及COPD不同严重程度分级间血浆5-HT浓度差异均无统计学意义;〈65岁健康组,吸烟者及戒烟者血浆5-HT浓度显著高于非吸烟者(P〈0.05),≥65岁健康组戒烟者血浆5-HT浓度对比〈65岁健康对照组戒烟者显著降低(P<0.05),COPD组无论是不同年龄段及吸烟状况,各组间5-TH浓度无差异;在有吸烟史的对照组和COPD组中吸烟指数与血浆5-HT浓度无明显相关性,对照组有吸烟史者年龄与血浆5-HT浓度呈负相关(r=-0.391,P=0.007)。结论在COPD炎症状态下,血浆5-HT浓度明显升高,吸烟、年龄等因素可能对其有一定影响,高水平的血浆5HT聚集在肺部血管系统内可能是诱导及加重COPD炎症反应的重要因素。
Objective To explore the role of plasma 5-HT in chronic obstructive pulmonary disease (COPD). Methods Sixty-five COPD patients and sixty elderly healthy controls were collected. All the selected cases routinely measured the pulmonary function parameters, plasma 5-HT levels were detected in healthy control group by ELISA, and also obtained in COPD group respectively on the time of acut6 exacerbation and stable period. Results Plasma 5-HT levels of COPD group on the time of acute exacerbation and stable period were significantly higher than healthy control group (P〈0.01). No significant difference in plasma 5-HT levels between the time of AECOPD and the COPD stable period, or across COPD severity. In healthy group〈65 years old, plasma 5-HT levels were significantly higher in current smokers or ex smokers than in non-smokers( P〈0.05). In healthy group, plasma 5-HT levels were significantly higher in ex-smokers≥65 years old than ex-smokers〈 65 years old ( P 〈0.05). In COPD group across every age and smoking conditions There were no significant differences in plasma 5- HT levels. In ever-smokers (healthy group and COPD group), there were no significant correlation between plasma 5-HT levels and smoking index. There were significant correlation between plasma 5-HT levels and age in healthy ever-smokers ( r =-0. 391, P = 0. 007). Conclusions Plasma 5-HT levels are significantly higher in COPD group, Some factors such as cigarette smoke and age could produce some effects on 5 HT levels, high plasma 5-HT levels which accumulates in the pulmonary vasculature may play important roles in inducing and aggravating inflammatory reaction in COPD.
