目的:探讨北京城区主要气传花粉的分布与过敏性疾病就诊诊次的关系。方法:应用改良花粉采样器于2015-01-01-2015-12-31期间对北京城区气传花粉浓度进行监测。通过医院计算机中心HIS系统统计同一时段变态反应科、耳鼻咽喉科和呼吸科门诊就诊患者情况。对诊次和花粉数量进行Pearson相关性分析。结果:(1)2015年北京城区的花粉总数为76 164粒。花粉季节约占全年天数的55.6%,全年花粉分布呈现两个高峰,分别为3~4月(29.7%、34.8%)和8~9月(9.9%、10.5%)。春季主要致敏花粉为柏属、悬铃木、杨属等,秋季为蒿属、藜科/苋、葎草/大麻等。(2)变态反应科和耳鼻咽喉科变应性鼻炎就诊高峰期分别出现在3~4月和8~9月。2个科室变应性鼻炎就诊规律高度正相关(r=0.625,P<0.05)。变态反应科过敏性哮喘仅出现秋季就诊高峰,耳鼻咽喉科和呼吸科未见就诊高峰。变态反应科变应性鼻炎与哮喘诊次高度正相关(r=0.902,P<0.01)。(3)全年花粉分布高峰春季高于秋季,但变应性鼻炎及哮喘就诊高峰秋季大于春季,花粉与诊次Pearson相关性分析无显著相关性(P>0.05)。结论:北京城区花粉分布高峰期与变应性鼻炎及哮喘就诊高峰期一致。北京城区春季花粉数量高于秋季,但花粉相关疾病就诊高峰出现在秋季,提示秋季花粉致敏性更强,影响范围更广。
Objective: To investigate the relationship between the distribution of major airborne pollen and the number of visits to allergic diseases in urban areas of Beijing. Methods: The pollen concentration in Beijing city was monitored by modified pollen sampler during 2015-01-01-2015-12-31. Through the hospital computer center HIS system statistics at the same time the Department of allergy, otolaryngology and respiratory outpatient treatment of patients. Pearson correlation analysis was performed on the number of visits and the number of pollen. Results: (1) The total number of pollen in Beijing urban areas in 2015 was 76,164. The pollen season accounted for 55.6% of the annual number of the year. The pollen distribution showed two peaks throughout the year, ranging from March to April (29.7%, 34.8%) and August to September (9.9%, 10.5%) respectively. Primarily the spring prickly ash is cypress, Platanus, Populus and so on, autumn is artemisia, Chenopodiaceae / amaranth, hemp grass / hemp and so on. (2) allergic rhinitis and otolaryngology allergic rhinitis peak at 3 to 4 months and 8 to 9 months. There was a significant positive correlation between the two departments’ treatment of allergic rhinitis (r = 0.625, P <0.05). Allergic Allergy Asthma only appeared in the autumn peak treatment, otolaryngology and respiratory department did not see the peak. Allergic allergic rhinitis and asthma clinically high correlation (r = 0.902, P <0.01). (3) The annual pollen distribution peak was higher in spring than in autumn, but the highest peak of allergic rhinitis and asthma treatment in spring was larger than that in spring, and there was no significant correlation between pollen and clinic Pearson correlation (P> 0.05). Conclusion: The peak pollen distribution in Beijing urban area is consistent with the peak period of allergic rhinitis and asthma. The number of spring pollen in Beijing urban area was higher than that in autumn, but the pollen-related disease peak appeared in autumn, which suggested that pollen allergens in autumn were stronger and affected a wider range.
