To observe the curative effect of Qingjin Huatan tang combined with western medicine on community-acquired pneumonia.Methods：A total of 175 cases of patients with community-acquired pneumonia of phlegm-heat obstructing the lung type were divided into the control group and the observation group according to the random number table method，85 and 90 cases in each group respectively.Both groups were treated with levofloxacin hydrochloride injection combined with amoxicillin and clavulanate potassium for injection，and the observation group was additionally treated with Qingjin Huatan tang.Both groups were treated for one week.Before and after treatment，the scores of symptoms and signs in the two groups were evaluated， and the levels of interleukin-17(IL-17)， white blood cell count(WBC)， tumor necrosis factor-α (TNF-α)and hypersensitive c-reactive protein(hs-CRP)in serum were detected.The extinction time of fever， the stopping time of cough， the extinction time of expectoration， the disappearance time of rales and the hospitalization time were recorded.The clinical effect in the two groups was compared.Results：After treatment，the total effective rate was 78.8%in the control group and 92.2%in the observation group，the difference being significant(P＜0.05).The scores of fever，cough，expectoration and rales in the lung in the two groups were lower than those before treatment(P＜0.01)，and the above scores in the observation group were lower than those in the control group(P＜0.05，P＜0.01).The levels of WBC，TNF-α，hs-CRP and IL-17 in the two groups were decreased when compared with those before treatment(P ＜ 0.01)，and the above four indexes in the observation group were lower than those in the control group，differences being significant(P ＜ 0.01).The extinction time of fever，the stopping time of cough，the extinction time of expectoration，the disappearance time of rales and the hospitalization time in the observation group were shortened when compared with those in the control group，differences being significant(P＜ 0.01).Conclusion：The therapy of Qingjin Huatan tang combined with routine western medicine in treating community-acquired pneumonia has better anti-inflammatory effect，which can improve clinical effect， reduce symptoms more quickly， shorten hospitalization time and save hospitalization expenses.
