摘要
目的探讨慢性阻塞性肺疾病(COPD)患者血清Clara细胞分泌蛋白(CC16)、转化生长因子-β1(TGF-β1)水平与肺功能的相关性。方法选择2018年5月至2019年7月新乡医学院第一附属医院呼吸内科收治的COPD患者100例为观察对象(COPD组),并按照气流受限程度的肺功能分级将COPD组患者分为轻中度组(n=39)、重度组(n=40)和极重度组(n=21);另选择同期体检健康者50例为对照组。所有受试者于入组当天抽取空腹肘静脉血,检测血清CC16、TGF-β1水平,并采用肺功能检测仪检测肺功能。采用Spearman相关分析COPD患者血清CC16、TGF-β1与第1秒用力呼气容积占预计值百分比(FEV1%pred)、第1秒用力呼气容积与用力肺活量比值(FEV1/FVC)的相关性,采用受试者工作特征(ROC)曲线分析血清CC16、TGF-β1在COPD中的诊断价值。结果COPD组患者的FEV1%pred、FEV1/FVC显著低于对照组(Z=-8.813、-9.967,P<0.05)。COPD组患者血清CC16水平低于对照组,血清TGF-β1水平高于对照组(Z=-7.288、-7.144,P<0.05)。COPD重度组和极重度组患者血清CC16水平低于COPD轻中度组(P<0.05),COPD极重度组患者血清CC16水平低于COPD重度组(P<0.05);COPD重度组和极重度组患者血清TGF-β1水平高于COPD轻中度组(P<0.05),COPD极重度组患者血清TGF-β1水平高于COPD重度组(P<0.05)。COPD患者血清CC16水平与FEV1%pred、FEV1/FVC%呈正相关(r=0.819、0.684,P<0.01),血清TGF-β1水平与FEV1%pred、FEV 1/FVC%呈负相关(r=-0.821、-0.761,P<0.01)。CC16诊断COPD的ROC曲线下面积为0.866(P<0.05),临界值为98.13μg·L^-1,灵敏度为72.0%,特异度为98.0%,约登指数为0.72;TGF-β1诊断COPD的ROC曲线下面积为0.858(P<0.05),临界值为688.20 ng·L^-1,灵敏度为74.0%,特异度为96.0%,约登指数为0.70。结论血清CC16、TGF-β1水平与COPD患者肺功能有相关性,对COPD具有一定的诊断价值,可用于COPD患者气流受限程度的评估,有望成为辅助COPD临床诊断的新型生物标志物。
Objective To investigate the correlation between serum clara cell secretory protein(CC16),transforming growth factor-β1(TGF-β1)levels and pulmonary function in patients with chronic obstructive pulmonary disease(COPD).Methods One hundred patients with COPD admitted to Department of Respiratory,the First Affiliated Hospital of Xinxiang Medical University were selected as subjects.According to the lung function classification of the airflow limitation,the patients were divided into mild-moderate group(n=39),severe group(n=40)and extremely severe group(n=21);and 50 healthy persons in the same period were selected as control group.The fasting elbow venous blood of all subjects was extracted on the day of enrollment,and the serum CC16 and TGF-β1 levels were detected.The lung function was detected by lung function tester.The correlation between serum CC16,TGF-β1 and one second forced expiratory volume as a percentage of the expected value(FEV1%pred),ratio of forced expiratory volume in one second to forced vital capacity(FEV1/FVC)in patients with COPD was analyzed by Spearman correlation.Receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of serum CC16 and TGF-β1 in COPD.Results The FEV1%pred and FEV1/FVC in the COPD group were significantly lower than those in the control group(Z=-8.813,-9.967;P<0.05).The serum CC16 level in the COPD group was lower than that in the control group,and the serum TGF-β1 level was higher than that in the control group(Z=-7.288,-7.144;P<0.05).The serum CC16 level in the severe and extremely severe groups was lower than that in the mild-moderate group(P<0.05),and the serum CC16 level in the extremely severe group was lower than that in the severe group(P<0.05).The serum TGF-β1 level of COPD patients in the severe and extremely severe groups was higher than that in the mild-moderate group(P<0.05),and the serum TGF-β1 level of COPD patients in the extremely severe group was higher than that in the severe group(P<0.05).The serum CC16 level was positivel
