【摘要】 目的 探討慢性阻塞性肺疾病(COPD)患者血清中白細胞介素-21(IL-21)表達水平及其與
肺功能、生活質量的相關性。方法 30例COPD急性加重期患者作為急性加重期COPD組, 30例COPD穩定期患者作為穩定期COPD組, 30例健康體檢者作為對照組, 采用Th1/Th2/Th17定量抗體芯片檢測各組IL-21水平, 采用意大利科時邁肺功能儀檢查各組肺功能, 采用COPD評估測試量表(CAT)評定各組生活質量, 并分析IL-21水平與肺功能、生活質量的相關性。結果 急性加重期COPD組IL-21水
平、CAT評分均高于穩定期COPD組和對照組, 一秒鐘用力呼氣容積占預計值百分比(FEV1%)、一秒鐘用力呼氣容積占用力肺活量百分比(FEV1/FVC)均低于穩定期COPD組和對照組, 差異均具有統計學意義(P<0.05);穩定期COPD組IL-21水平、CAT評分均高于對照組, FEV1%、FEV1/FVC均低于對照組, 差異均具有統計學意義(P<0.05)。相關性分析顯示, 穩定期COPD患者血清IL-21水平與一秒鐘用力呼氣容積(FEV1)、FEV1/FVC、用力肺活量(FVC)呈負相關(r=-0.315、-0.198、-0.593, P<0.05), 穩定期COPD患者血清IL-21水平與CAT評分呈正相關(r=0.382, P<0.05);急性加重期COPD患者血清IL-21水平與FEV1、FEV1/FVC、FVC呈負相關(r=-0.693、-0.485、-0.149, P<0.05), 急性加重期COPD患者血清IL-21水平與CAT評分呈正相關(r=0.682, P<0.05)。結論 COPD患者血清中IL-21呈高表達, 且與肺功能、生活質量存在緊密聯系。

【Abstract】 Objective To discuss the expression of interleukin -21 (IL-21) in serum of chronic obstructive pulmonary disease (COPD) patients and its correlation with lung function and quality of life.
Methods There were 30 patients with acute exacerbation of COPD as acute exacerbation COPD group,
30 stable COPD patients as stable COPD group, and 30 physical examination people as control group. Th1/Th2/Th17 quantitative antibody chip was used to detect IL-21 levels in each group. Lung function in each group was examined by Italy Keshimai lung function instrument. COPD assessment test (CAT) was used to assess the quality of life in each group, and the correlation between IL-21 level and lung function and quality of life was analyzed. Results Acute exacerbation COPD group had higher IL-21 level and CAT score than stable COPD group and control group, and lower forced expiratory volume in 1 second percentage of expected value (FEV1%) and forced expiratory volume in 1 second percentage of forced vital capacity (FEV1/FVC) than stable COPD group and control group. Their difference was statistically significant (P<0.05). Stable COPD group had higher IL-21 level and CAT score than control group, and lower FEV1% and FEV1/FVC than the control group. Their difference was statistically significant (P<0.05). The correlation analysis showed that the level of serum IL-21 was negatively correlated with forced expiratory volume in 1 second (FEV1), FEV1/FVC, and forced vital capacity (FVC) in patients with stable COPD (r=-0.315, -0.198, -0.593, P<0.05), and the level of serum IL-21 was positively correlated with the CAT score in patients with stable COPD (r=0.382, P<0.05). The level of serum IL-21 in patients with acute exacerbation of COPD was negatively correlated with FEV1, FEV1/FVC and FVC (r=-0.693, -0.485, -0.149, P<0.05), and the level of serum IL-21 was positively correlated with the CAT score in patients with acute exacerbation of COPD (r=0.682, P<0.05). Conclusion The level of IL-21 in serum of patients with COPD is high, and it is closely related to lung function and quality of life.endprint

COPD是目前人們生活中一種可以預防和治療的常見病、多發病, 它是以持續存在的氣流受限為特征的呼吸道疾病, 本病的發生、發展與肺部對吸入有害氣體(如煙草霧等)或顆粒引起的異常炎癥反應有關, 患者發病后常伴有炎性因子的失衡[1]。文獻報道顯示[2]:COPD屬于一種相對獨立的疾病, 常規方法以肺功能診斷為主, 但是該方法并不能評價患者的生活質量情況。IL-21參與多種自身免疫性疾病的發生、發展, 其在炎性環境中起著相對重要的作用。因此, 加強IL-21在COPD患者中的表達及與肺功能、生活質量的相關性研究, 對改善患者預后具有重要的意義, 本文即對此進行研究, 具體報告如下。
