摘要:

目的 探索慢性阻塞性肺疾病(COPD)患者稳定期与急性加重期气道内 SLPI 表达水平差 异,明确 COPD 患者肺功能与气道内 SLPI 表达水平相关性。方法 纳入 40 COPD 患者及 40 例健康成人为研究对象,检测健康成人痰液中的 SLPI 浓度及 COPD 患者稳定期和急性加重期痰液中的 SLPI 浓度和肺功能(FEV1%pred,FEV1/FVC),比较 COPD 患者气道内 SLPI 水平与健康成人差异及稳定期与急性加重期差异,并分析 SLPI 表达水平与肺功能相关性。结果 稳定期 COPD 患者与健康志愿者气道内 SLPI 表达水平差异无统计学意义[(46.74 ± 2.30)μg/L vs.(47.60 ± 2.50)μg/L,t=1.321,P=0.190]。COPD 患者急性加重期较稳定期气道内 SLPI 水平明显降低[(38.148 ± 3.59)μg/L vs.(46.74 ± 2.30)μg/L,t=35.707,P 0.01]。COPD 患者稳定期气道内 SLPI 表达水平与 FEV1/FVC 没有明显相关性(r=0.215,P=0.183),但与 FEV1 呈正相关(r=0.466,P=0.002);COPD 患者急性加重期气道内 SLPI 表达水平与 FEV1/FVC 没有明显 相关性(r=0.088,P=0.589),但与 FEV1%Pred 呈正相关(r=0.369,P=0.019)。结论 COPD 患者急性加重期较稳定期气道内SLPI 水平明显降低,气道内SLPI 表水平与FEV1%Pred 呈正相关。

Abstract:

Objective To explore the difference of secretory leukocyte proteinase inhibitor(SLPI)expres⁃ sion in airway between stable and acute exacerbation chronic obstructive pulmonary disease(COPD)patients,and to clarify the correlation between pulmonary function and the expression of SLPI in airway. Methods A total of 40 COPD patients and 40 healthy adults were included as the objects. SLPI concentration in the sputum of healthy adults and COPD patients and lung function were measured. The difference of SLPI level between COPD patients and healthy adults,and between stable and acute exacerbation COPD was compared. The correlation between SLPI expression and lung function was analyzed. Results There was no significant difference in the expression of SLPI in airway between COPD patients and healthy adults[(46.74 ± 2.30)μg/L vs.(47.60 ± 2.50)μg/L,t=1.321,P 0.190]. The level of SLPI in acute exacerbation COPD patients was significantly lower than that in stable COPD pa⁃ tients[(38.15 ± 3.59)μg/L vs.(46.74 ± 2.30)μg/L,t=35.707,P=0.01]. There was no significant correlation be⁃ tween SLPI and FEV1/FVC(r=0.215,P=0.183),but SLPI was positively correlated with FEV1% Pred(r 0.466,P=0.002)in stable COPD patients. There was no significant correlation between SLPI and FEV1/FVC(r 0.088,P=0.589),but SLPI was positively correlated with FEV1%Pred(r=0.369,P=0.019)in acute exacerba⁃ tion COPD patients. Conclusions SLPI in airway of acute exacerbation COPD patients was significantly lower than that of stable COPD patients. SLPI in airway is positively correlated with FEV1% Pred in COPD patients.
