Therapeutic Effect of Different Treatment Course With Inhaled Corticosteroids in Eosinophilic Bronchitis Patients

Summary

This study aims to observe the therapeutic effect of different treatment course with inhaled corticosteroids in eosinophilic bronchitis patients. The investigators hypothesize: 1. Cough score will be improved after treatment with longer treatment course with inhaled corticosteroids in EB patients. 2. The sputum eosinophil percentage will be decreased and recovered to normal level (Eos%\<2.5%) with longer treatment course with inhaled corticosteroids in EB patients. 3. The rate of recurrence after treatment will be decrease with longer treatment course with inhaled corticosteroids in EB patients
