To explore the effects of Yiqi Wenyang Prescription on the airway function and inflammatory factor level of patients with allergic rhinitis.Methods:A total of 88 cases patients with allergic rhinitis admitted in Sanya Hospital of Chinese Medicine from January to December 2017 were selected and randomly divided into a control group (n=44) and an observation group (n=44) according to order of admission.Patients in the control group were treated with menglusite sodium chewing tablets,bryderonide spray,while patients in the observation group were treated with Yiqi Wenyang Prescription on the basis of the control group.The efficacy in the 2 groups was evaluated after treating continuously for 3 weeks and regularly followed-up for 6 months.The clinical efficacy in the 2 groups was evaluated after treatment.The main symptoms and signs improvement,airway function indexes and serum inflammatory factors levels before and after treatment were detected and compared.The recurrence and the occurrence of adverse reactions in the 2 groups during followed-up period were recorded and compared.Results:The clinical total effective rate in the observation group after treatment was 9318%,which was higher than 7727% in control group (P<005); Compared with before treatment,the scores of nasal itching,nasal congestion,runny nose,sneezing,turbinate enlargement and serum IL-6,IL-8 levels in the 2 groups after treatment decreased,and the observation group was lower than that of the control group (P<001); The FCV,FEV1/FVC,PEF and serum IL-10 levels in the 2 groups and the FEV1 in the observation group after treatment increased (P<001),and the observation group was higher than that of the control group (P<001); There was no significant difference in the recurrence rate 3 months after treatment between the 2 groups (P>005),while the recurrence rate 6 months after treatment in the observation group was lower than that in control group significantly (P<005).No serious adverse reaction occurred in the 2 groups during the followed-up period.Conclusion:Yiqi Wenyang Prescription can improve the clinical symptoms of patients with allergic rhinitis effectively,inhibit the body's inflammatory response and enhance the airway function,prevent the recurrence of patients with good security.The clinical efficacy is better than conventional western medicine treatment significantly.
