Abstract:
OBJECTIVE To discuss the relationship between the main concentration of air-borne pollen and the number of visits for allergic diseases in Chengde City. METHODS The daily airborne pollen concentration and species in Chengde City,Hebei Province were monitored by gravity sedimentation method from March 1 to October 15,in 2020-2022. The number of visits of patients with allergic rhinitis,asthma and conjunctivitis in department of otorhinolaryngology,respiratory and ophthalmology were counted by HIS system in the hospital computer center,furthermore,the correlation between pollen concentration and the number of visits of the above diagnosed patients was analyzed. RESULTS The pollen concentration in Chengde showed two peaks each year,which were in May in spring and August in autumn. The main pollen sources in spring were Pinaceae,ash,birch,ulmaceae,Cupressaceae,Moraceae and Rosaceaceae,accounting for 82.6％ of the total annual pollen(78.2％,83.5％,and 86.1％ in 2020-2022,respectively). In autumn,artemisia and humulus were the main sources of pollen,accounting for 9.94％ of the total annual pollen(11.4％,6.3％,12.11％,in 2020-2022,respectively). The number of outpatient visits patients with allergic rhinitis,asthma and conjunctivitis were higher in May and August than in other months,and the number of patients with allergic rhinitis in August was significantly increased compared with other months(P<0.05). The total monthly visits of the three departments and the visits of the three allergic diseases were positively correlated with pollen concentration. CONCLUSION The pollen concentration in the spring and autumn seasons of Chengde City has a direct impact on allergic diseases. Monitoring and broadcasting pollen concentration can provide early warning for doctors and patients,and provide effective information for early intervention,protection,and reasonable treatment of diseases.
