RESUMO
Objective: To observe the clinical efficacy of modified Xiaofengsan and its effect on cytokines in persistent asthma patients with wind-asthma pattern. Method: The 120 eligible patients with chronic and persistent asthma were randomly divided into control group (60 cases) and treatment group (60 cases). Patients in control group received the budesonide/formoterol (160 μg/4.5 μg, 2 inhales/time, bid). Patients in treatment group additionally received the modified Xiaofengsan combined with budesonide/formoterol (160 μg/4.5 μg). The treatment course was 1 month in both groups. The clinical efficacy of the two groups was observed. Before and 3 months after treatment, asthma control test (ACT) and the average times of acute exacerbation in 6 months before and after treatment between two groups were observed; percentage of forced expiratory volume in first second and its predicted value (FEV1%), variety ratio of Peak expiratory flow (PEF), eosinophilic granulocyte (EOS) count in peripheral blood and the levels of interleukin-4(IL-4), interleukin-6(IL-6) and interleukin-13(IL-13) in serum were measured before and after treatment respectively. In addition, the safety of the two groups was evaluated. Result: The total effective rate of the treatment group was higher than that of the control group (P1% in treatment group were higher(PPConclusion: Modified Xiaofengsan combined with budesonide/formoterol could relieve symptoms of asthma, improve pulmonary function and lower the levels of IL-4, IL-6 and IL-13 in serum.
