ABSTRACT

Objective To observe the clinical effect of modified Zhisou powder and Symbicort Turbuhaler simultaneously on patients with Cough Variant Asthma. Methods 120 patients with Cough Variant Asthma were randomly recurited into two groups. 60 patients in the treatment group were treated with modified Zhisou powder and Symbicort Turbuhaler; 60 patients in the control group were treated with Symbicort Turbuhaler. 4 weeks was a therapeutic course in both group. Results The markedly controlled rate (MCR) (clinical control+excenence)of the treatment group was 83.3%, obviously surpassed the control group (70.0%) (P＜0.05); There was obvious improvement of cough, expectoration, breath lessness and throaty pruritus after the therapy in both groups, but it was much better in the treatment group than the control group(P＜0.05). The pulmonary function was significantly improved after treatment in both groups(FEV1, FEV1% and PEF, P＜0.05). The improvement showed significant difference between the two groups(P＜0.05). There was obvious decrease of EOS, IL-5 and ECP in both groups. The decrease of ECP and IL-5 in the treatment group was greater than the control group(P＜0.01). Conclusion The therapy of modified Zhisou powder and Symbicort Turbuhaler has advantage over pure western therapy.
