Abstract：Objective：To observe the clinical effect of modified Banxia Houpu tang and Sanzi Yangqin tang combined with western medicine for community-acquired pneumonia. Methods：A total of 86 cases of patients with community-acquired pneumonia were selected and divided into the control group and the observation group according to the random number table method，43 cases in each group. The control group was given routine treatment of western medicine，and the observation group was additionally given modified Banxia Houpu tang and Sanzi Yangqin tang based on the treatment of the control group. Both groups were continuously treated for ten days. The disappearance time of symptoms and signs，white blood cell count and neutrophil count， Clinical Pulmonary Infection Score(CPIS)， and the clinical effect were compared between the two groups. Results：The disappearance time of fever，cough，and the lung rale in the observation group was earlier than that in the control group， differences being significant(P＜0.05). Before treatment， when compared white blood cell count， neutrophil count，and CPIS between the two groups，there was no significance being found in differences(P＞0.05). After treatment， white blood cell count， neutrophil count， and CPIS in the two groups were decreased when compared with those before treatment(P＜0.05)，and the three indexes above in the observation group were lower than those in the control group(P＜0.05). The total effective rate was 95.35% in the observation group， higher than that of 76.74% in the control group， the difference being significant(P＜0.05). Conclusion： In the treatment of community- acquired pneumonia， the therapy of modified Banxia Houpu tang and Sanzi Yangqin tang combined with western medicine has significant curative effect，which can shorten recovery time of clinical symptoms，and reduce inflammatory response.
