Results CVA remission in treatment group was significantly better than that in the control group( P 0. 05). Developed into a typical asthma proportion in the treatment group was significantly lower than that in the control group( P 0. 05). Negative conversion ratio of BPT in treatment group was higher than that in control group( P 0. 05).
