【摘要】：目的:探讨北京地区树木花粉的致敏特点,并分析其与气传花粉的关系。方法:将2017年1~7月份变态反应科就诊的2 521例过敏性疾病患者纳入研究,均接受8种树木花粉变应原点刺试验(SPT)。结果:(1)树木花粉SPT阳性率为49.3%(1 244/2 521)。男性致敏率高于女性(56.4%vs 45.0%,P0.01)。儿童组花粉致敏阳性率显著高于成人组(55.9%vs 48.6%,P0.05)。树木花粉致敏趋向于多重致敏,≥3种树木花粉阳性率为26.3%,占总阳性人群的53.3%。(2)树木花粉致敏的阳性率呈现典型的季节高峰,3月份阳性率最高(62.2%),其次为5月份(52.1%),最低为1月份(27.9%)。花粉致敏阳性率与空气中花粉总量高度相关(r=0.929,P0.01)。(3)圆柏花粉点刺阳性率最高(34.6%),其次为杨树(21.3%),槐树(13.3%)。不同花粉的致敏率和空气中的含量高度相关(r=0.714,P0.05)。结论:北京地区主要致敏树种为圆柏。春季树木花粉致敏呈现季节性,3月份为致敏高峰期。春季树木花粉致敏率与空气中的播散量有关。

Methods: a total of 2 521 patients with allergic diseases were enrolled in the study in 2017 and July. The results showed that the SPT positive rate of pollen was 49.3% (1 244/2 521). The sensitizing rate of male was higher than that of female (56.4 vs 45.0%). The positive rate of pollen sensitization in children was significantly higher than that in adults (55.9 vs 48.6P0.05). The positive rate of pollen sensitization of trees 鈮，
