Objective We detected the changes of Airway remodeling,lung function and peripheral blood concentrations of TGF-β in asthmatic children before and after inhaled budesonide, and explored the role of budesonide in airway remodeling before early intervention in asthmatic children. Methods 32 cases of children were diagnosed asthma in our hospital,and given treatment of inhaled budesonide for 6 months, and to detect lung function,pheral blood TGF-β concentration as well as measuring the bronchial wall thickness (T) and calculate the wall area (WA), the outer diameter of the trachea and bronchial wall thickness ratio (WT%), the cross-sectional area of the airway wall accounted for airway percentage (WA%) of the total cross-sectional area by high-resolution CT (HRCT) before and after treatment. Results After treatment with inhaled budesonide in six months, the asthma WT%, WA%, lung function, and TGF-β concentrations were significantly improved, the differences compared with that before treatment were statistically significant(P<0.05). Conclusion The treatment of inhaled budesonide can alleviate asthmatic airway remodeling in early, improve lung function,possibly related to down the expression TGF-β.
