摘要
目的
2
研究补肺活血胶囊对慢性阻塞性肺疾病（简称“慢阻肺”）大鼠模型气道炎症及黏液高分泌的干预作用和机制。
方法
2
采用烟熏并气道内滴注脂多糖的方法制备慢阻肺大鼠模型。40只Wistar大鼠随机分为空白对照组、模型组、补肺活血组和茶碱组，空白对照组及模型组予以生理盐水灌胃，补肺活血组和茶碱组分别予补肺活血胶囊和茶碱缓释片溶液灌胃。使用小动物肺功能仪检测大鼠肺功能，苏木精-伊红染色和阿利新蓝-过碘雪芙染色进行形态学分析，酶联免疫吸附实验检测肺泡灌洗液中IL-1β、IL-6、NE、TGF-β、EGF、IL-13和TNF-α的表达，免疫组化法检测大鼠肺组织中黏蛋白5AC（Muc5ac）的表达，免疫印迹法检测Toll样受体4（TLR4）、髓样分化初级应答基因88（MyD88）、NF-κB、Muc5ac、EGFR/p-EGFR、PI3K/p-PI3K、AKT/p-AKT的蛋白表达。

Abstract
Objective
2
To investigate the intervention effect and mechanism of Bufei Huoxue Capsule on airway inflammation and mucus hypersecretion in rats with chronic obstructive pulmonary disease （COPD） .
Methods
2
The rat model of COPD was established by smoking and intratracheal instillation of lipopolysaccharide . The lung function was measured by small animal lung function meter， and the morphology of airway epithelial cells was detected by hematoxylin-eosinstaining and alicinblue-periodopho staining， the expressions of IL-1β， IL-6， NE， TGF-β， EGF， IL-13 and TNF-α in BALF were detected by enzyme-linked immunosorbent assay ， the protein expressions of TLR4， Myd88， NF-κB， Muc5ac， EGFR/p-EGFR， PI3K/p-PI3K， Akt/p-AKT were detected by Western-blot， and the expression of Muc5ac was detected by immunohistochemistry.

Conclusion
2
Bufei Huoxue Capsule can improve lung injury by inhibiting airway inflammation and mucus hypersecretion in rats with COPD.
