摘要目的 探讨血清胸腺基质淋巴细胞生成素(TSLP)、血清淀粉样蛋白A(SAA)、C反应蛋白(CRP)在慢性阻塞性肺疾病(COPD)患者不同时期中的水平变化.方法 收集慢性阻塞性肺疾病急性加重(AECOPD)患者共33例,以其经治疗后进入稳定期时作为前后对照,健康人16例为正常对照.测定两组血清TSLP、SAA、CRP水平,并分析各指标在COPD不同时期中的变化.结果 COPD组急性期CRP与SAA水平均高于稳定期,TSLP水平低于健康对照组,差异有统计学意义(P＜0.05).COPD患者中CRP与SAA呈正相关(r=0.546,P=0.000).CRP(AUC=0.797)和SAA(AUC =0.815)在确定COPD患者不同分期中有统计学意义(P＜0.05).结论 血清TSLP水平在AECOPD患者下降,CRP和SAA在AECOPD患者增加,其中SAA区分COPD与AECOPD患者的准确性更好.

abstractsObjective To value different stages of chronic obstructive pulmonary disease (COPD) patients with the detection of the levels of serum thymic stromal lymphopoietin (TSLP),serum amyloid A (SAA),and C-reactive protein (CRP).Methods A total of 33 patients with COPD during and after hospitalization and 16 healthy controls were enrolled in the study from the 3rd affiliated hospital of SYSU.Differences and correlations of the level of serum TSLP,SAA and CRP were analyzed to value the veracity of those factors in different stages of COPD.Results The levels of CRP and SAA were higher in acute exacerbation of COPD (AECOPD) group than stable COPD group,TSLP was lower in the AECOPD group than the healthy control group (P ＜ 0.05).CRP had a positive correlation with SAA (correlation r =0.546,P =0.000),CRP [area under curve (AUC) =0.797] and SAA (AUC =0.815),and they were statistically significant in identity of different stages of COPD (P ＜ 0.05).Conclusions Serum TSLP level is decreased in acute exacerbation phase of COPD.CRP and SAA are increased in AECOPD.SAA is more confident in identity of different phases of COPD.
