【摘要】:目的:探讨慢性阻塞性肺疾病(慢阻肺)急性加重期患者治疗前后血清4-HNE水平变化的临床意义。方法:收集2013年1月-2015年5月在山西医科大学附属大医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,平均年龄在(67±9)岁;健康对照者50例,与慢阻肺急性加重期组患者性别、年龄相匹配。分组方法:1.慢阻肺急性加重期组和健康对照组;2.慢阻肺急性加重期患者分组如下:(1)肺功能Ⅰ-Ⅱ级组和肺功能Ⅲ-Ⅳ级组;(2)B组(低风险多症状组)和D组(高风险多症状组);(3)合并心血管疾病组和无心血管疾病组;(4)嗜酸性粒细胞≤2%组和嗜酸性粒细胞2%组。采用酶联免疫吸附试验法测定各组患者血清4-HNE水平。结果:1.与健康对照组(9.38±3.0)mg/l比较,慢阻肺急性加重期患者治疗前(18.5±5.2)mg/l,治疗后(19.0±5.1)mg/l,血清4-HNE水平均明显增高,差异均有统计学意义(P0.05)。2.慢阻肺急性加重期各组治疗前后及各组间治疗前比较血清4-HNE水平差异均无统计学意义(P0.05)。3.肺功能Ⅰ-Ⅱ级组和肺功能Ⅲ-Ⅳ级组及B组和D组,治疗后血清4-HNE水平下降的比例分别为43.8%和50.0%及46.7%和54.5%,差异均无统计学意义(P0.05)。4.合并心血管疾病组和无心血管疾病组及嗜酸性粒细胞≤2%组和嗜酸性粒细胞2%组,治疗后血清4-HNE水平下降的比例分别为25.0%和66.7%及73.3%和32.0%,差异均有统计学意义(P0.05)。5.慢阻肺急性加重期患者治疗前和治疗后血清4-HNE水平与FEV1占预计值百分比(FEV1%pred)均无相关性(P0.05)。结论:慢阻肺慢阻肺急性加重期患者全身系统性氧化应激反应及炎症反应增强,合并心血管疾病及外周血嗜酸性粒细胞2%的慢阻肺急性加重期患者在治疗后仍持续存在较高的系统性氧化应激反应;4-HNE可能成为慢阻肺患者急性加重期的生物标志物,特别是合并心血管疾病或嗜酸性粒细胞增高的患者。
[Abstract]:Objective: to investigate the clinical significance of serum 4-HNE levels in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) before and after treatment. 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 卤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,
