【摘要】:目的:探討慢性阻塞性肺疾病(慢阻肺)急性加重期患者治療前后血清4-HNE水平變化的臨床意義。方法:收集2013年1月-2015年5月在山西醫(yī)科大學(xué)附屬大醫(yī)院呼吸科住院的慢阻肺急性加重期患者40例,其中有男性36例,女性4例,平均年齡在(67±9)歲;健康對照者50例,與慢阻肺急性加重期組患者性別、年齡相匹配。分組方法:1.慢阻肺急性加重期組和健康對照組;2.慢阻肺急性加重期患者分組如下:(1)肺功能Ⅰ-Ⅱ級組和肺功能Ⅲ-Ⅳ級組;(2)B組(低風(fēng)險多癥狀組)和D組(高風(fēng)險多癥狀組);(3)合并心血管疾病組和無心血管疾病組;(4)嗜酸性粒細(xì)胞≤2%組和嗜酸性粒細(xì)胞2%組。采用酶聯(lián)免疫吸附試驗(yàn)法測定各組患者血清4-HNE水平。結(jié)果:1.與健康對照組(9.38±3.0)mg/l比較,慢阻肺急性加重期患者治療前(18.5±5.2)mg/l,治療后(19.0±5.1)mg/l,血清4-HNE水平均明顯增高,差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。2.慢阻肺急性加重期各組治療前后及各組間治療前比較血清4-HNE水平差異均無統(tǒng)計(jì)學(xué)意義(P0.05)。3.肺功能Ⅰ-Ⅱ級組和肺功能Ⅲ-Ⅳ級組及B組和D組,治療后血清4-HNE水平下降的比例分別為43.8%和50.0%及46.7%和54.5%,差異均無統(tǒng)計(jì)學(xué)意義(P0.05)。4.合并心血管疾病組和無心血管疾病組及嗜酸性粒細(xì)胞≤2%組和嗜酸性粒細(xì)胞2%組,治療后血清4-HNE水平下降的比例分別為25.0%和66.7%及73.3%和32.0%,差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。5.慢阻肺急性加重期患者治療前和治療后血清4-HNE水平與FEV1占預(yù)計(jì)值百分比(FEV1%pred)均無相關(guān)性(P0.05)。結(jié)論:慢阻肺慢阻肺急性加重期患者全身系統(tǒng)性氧化應(yīng)激反應(yīng)及炎癥反應(yīng)增強(qiáng),合并心血管疾病及外周血嗜酸性粒細(xì)胞2%的慢阻肺急性加重期患者在治療后仍持續(xù)存在較高的系統(tǒng)性氧化應(yīng)激反應(yīng);4-HNE可能成為慢阻肺患者急性加重期的生物標(biāo)志物,特別是合并心血管疾病或嗜酸性粒細(xì)胞增高的患者。

Methods: from January 2013 to May 2015, 40 patients with acute exacerbation of COPD, including 36 males and 4 females, with an average age of (67 鹵9) years, were collected from the Department of Respiratory Medicine, affiliated Hospital of Shanxi Medical University, and 50 healthy controls. Gender and age matched with patients with acute exacerbation of COPD. The method of grouping is 1: 1. Chronic obstructive pulmonary disease in acute exacerbation group and healthy control group 2. The groups of patients with acute exacerbation of COPD are as follows: (1) pulmonary function 鈪,
