[To investigate the correlation of nasal secretions of eosinophils and lung function after the treatment of budesonide in the allergic rhinitis patients].

Objective:To identify the relationship between nasal secretion eosinophilia and pulmonary function of patients with AR after treatment of intranasal budesonide.Method:Fifty patients with moderate to severe AR were selected, and compared to 50 normals, all had pulmonary function and nasal secretion of eosinophil number check, experimental group of AR received budesonide+loratadine treatment for 3 months, and then had lung function and nasal secretion eosinophil again, analysised the trends of change between two. Result:Eosinophils of AR patients was higher than its of control group (P<0.05), lung function index MMEF and nasal secretion eosinophilia of 50 AR patients had a negative relationship(r=-0.945，P<0.05).Treated with eosinophils the number of nasal secretion eosinophilia of AR decreased 10 + 5.6, the difference compared to the before of the treatment was statistically significant(P<0.05), compared to the normal control group was significant(P<0.05). After the treatment of budesonide, the trends of change between nasal secretion eosinophils and pulmonary function was a positive correlation(r=0.803,P<0.01). Conclusion:The higher the number of eosinophils in nasal secretions of patients with AR, the more obvious the decline of lung function. After the treatment with budesonide, the more eosinophils decreased in patients with AR, the more obvious the improvement of pulmonary function.
