Methods: The author chose randomly sixty healthy children as the control group and one hundred and sixty children with asthma in acute period before ICS therapy as the experimental group. The experimental group were treated with ICS therapy and then eighty-nine children of this group were followed up for 3 months ,sixty-eight for 6 months and sixty for 12 months. The ICS in the study was budesonide with the trade name as Pulmicort.
