Abstract:

目的 通过观察 S100A8/A9 在不同分期慢性阻塞性肺疾病(简称慢阻肺)患者血浆和诱导痰中的水平及其与患者肺功能和血浆中炎症介质的相关性分析,探讨 S100A8/A9 在慢阻肺发病机制中的作用。 方法 收集 2013 年 8 月至 2014 年 1 月于川北医学院附属医院门诊就诊的稳定期和住院的急性加重期慢阻肺患者以及门诊健康体检者各 30 例。采用 ELISA 法检测三组研究对象血浆和诱导痰中 S100A8/A9 及血浆白细胞介素(IL)-1β、IL-8 和肿瘤坏死因子-ɑ (TNF-ɑ)的浓度。应用相关分析法对慢阻肺患者血浆、诱导痰中 S100A8/A9 与肺功能及血浆中炎症介质的相关性进行分析。 结果 慢阻肺急性加重期和稳定期组患者血浆及诱导痰中 S100A8/A9、血浆 IL-1β、IL-8、TNF-ɑ 的浓度均较健康对照组显著增高( P<0.01),而慢阻肺急性加重期组患者血浆及诱导痰中 S100A8/A9、血浆 IL-1β、IL-8、TNF-ɑ的浓度又较慢阻肺稳定期组显著增高( P<0.01)。慢阻肺患者血浆和诱导痰中 S100A8/A9 水平与 FEV 1%pred 呈负相关。慢阻肺患者血浆和诱导痰中 S100A8/A9 水平与血浆中 IL-1β、IL-8、TNF-α 的水平均呈正相关。 结论 慢阻肺患者体内 S100A8/A9 合成和释放显著增多,其 S100A8/A9 水平与气流受限严重程度和血浆炎症介质水平相关。提示 S100A8/A9 参与了慢阻肺的发生发展,可能主要参与慢阻肺的炎症机制
