4

6 of seizure period after treatment

the rhinoconjunctivitis quality of life questionnaire（RQLQ） score and total nasal symptom score（TNSS） were observed in the two groups; the rescue medication score（RMS） was recorded on week 1-6 of seizure period in the two groups. Results The seizure rate of the observation group was 84.0%（42/50）

which was lower than 100.0%（48/48） in the control group（P<0.05）. After treatment

the scores of RQLQ and TNSS at each time point of seizure period were decreased compared with before treatment in the observation group（P<0.01）

which were lower than the control group（P<0.01）. The RMS score at each time point of seizure period in the observation group was lower than the control group（P<0.05

P<0.01）. Conclusion Acupuncture can reduce the incidence of moderate to severe seasonal allergic rhinitis

relieve the symptoms
