[Abstract] Objective To explore the mechanism of Siwu Tang and Huoxue， Yangxue drug pairs in airway remodeling and mucosal immunity of rats with chronic obstructive pulmonary disease （COPD）. Methods 50 Wistar male healthy rats of SPF grade aged 8 weeks old were randomly divided into the normal control group， COPD model group， Siwu Tang group， Huoxue drug pair group， Yangxue drug pair group， according to the body weight of rats. The rats model of COPD was induced by smoke and lipopolysaccharide （LPS） infusion. The normal control group was given free drank water. After the model successfully established， the corresponding Chinese medicine 2 mL/（rat·d） was given by gavage in the drug groups for 4 weeks. The model group was given normal saline by the same way. 24 h after last administration， the rats of each group were sacrificed and the specimens were collected. Subsequently the pathological changes of the lung tissue were observed， and the levels of secretory immunoglobinA （SIgA）， secretory component （SC）， transforming growth factor-β1 （TGF-β1）， vascular endothelial growth factor （VEGF） in lung tissue were detected by ELISA. Results The pathology of rats lung tissue showed that airway inflammatory cells infiltrated in airway tissue， vessel stenosis， bronchial smooth muscle increased thickness， alveolar dilation and fusion in COPD model group； the pathology of the lung tissue changed better in Siwu Tang group， Huoxue drug pair group and Yangxue drug pair group. Compared with the normal control group， the levels of SIgA， SC， TGF-β1， VEGF increased in the COPD model group （P < 0.01）； after using corresponding traditional Chinese medicine， compared with the COPD model group， the levels of SIgA， SC， TGF-β1， VEGF decreased significantly （P < 0.01）. Conclusion SIgA， SC， TGF-β1， VEGF involves in the development of COPD. Siwu Tang， Huoxue and Yangxue drug pairs improve the mucosal immune balance and airway remodeling process in COPD by regulating the level of SIgA， SC， TGF-β1， VEGF.
