Objective To explore the effect of azelastine hydrochloride nasal spray combined with desloratadine to inflammatory factors, cell function and IgE of patients with allergic rhinitis.Methods 92 cases of allergic rhinitis patients treated in the first affiliated hospital of wenzhou medical college hospital from June 2014 to December 2015 were divided into experimental group(n=46) and control group(n=46) according to the random number table method.The control group was given oral loratadine tablets, one piece per time, one time per day, while the experimental group was given azelastine hydrochloride nasal spray on the basis of the control group,each nostril one spray, one time in the morning and night.The clinical efficacy of two groups of patients would be observed after 4 weeks,ELISA would be used to detect serum levels of IFN-γ, IL-4, IL-8 and IgE level, and IFN-γ/IL-4 was the value of Thl/Th2,flow cytometry instrument was used to the determination of T cell subgroup CD4 +,CD8 + cells.Results 4 weeks after treatment,stuffy nose, nasal itching, runny nose, sneezing and nasal cavity change points are lower than before the treatment in both the two groups.Experimental group obviously lower than the control group, the difference was statistically significant ( P <0.05 ).The total effective rate of treatment group is higher than the control group,the difference was statistically significant(χ2 =4.389,P=0.036).The serum level of IFN-γis higher than before treatment in both the two groups.IL-4, IL-8 inflammatory factor levels were lower than before treatment,the experimental group was better than control group,the difference was statistically significant(P<0.05).CD4 +,CD8 +of T cells and Thl/Th2 values are higher than before the treatment in both the two groups,the experimental group was higher than control group, the difference was statistically significant ( P<0.05 ).Serum IgE levels were lower than before the treatment in both the two groups,the experimental group was lower than control group,the difference was statistically significant (P<0.05).Conclusion The therapy of azelastine hydrochloride nasal spray combined with desloratadine can improve the clinical effect of the treatment of allergic rhinitis,reduce inflammation,strengthen the body's immune function, improve thelevel of serum IgE.
