目的 分析过敏性鼻炎患者血清吸人性过敏原总IgE和血清特异性IgE浓度,为临床预防和诊治提供科学依据。方法 采用过敏原特异性抗体IgE检测试剂盒和酶标仪，对吸人性过敏原进行检测。结果 785例过敏性鼻炎患者血清过 敏原总IgE皆为阳性（100% )，血清特异性IgE阳性率以户尘螨为最高（94. 27% ),其次为:春季花粉组合(60. 64% )、夏秋季花粉组合(53.50% )、短豚草（35. 29% )、霉菌组合(30.45% )、狗毛皮屑（6. 75% )。结论 承德地区过敏性鼻炎患 者应加强对户尘螨、春季花粉组合、夏秋季花粉组合等吸人性过敏原的防护，居室环境保持清洁、最大限度减少与过敏原的接触。

Objective To analyze the specific IgE antibodies of the inhalant allergens in the sera of patients with allergic rhinitis and provide a scientific basis for the clinical prevention，diagnosis and treatment of the disease. Methods The inhalant allergens in 785 patients with allergic rhinitis were detected by the specific allergenic antibody IgE test kit and enzyme- labeled instrument. Results The positive rates of the total IgE in 785 patients with allergic rhinitis were 100% . The positive rates of dermatophagoides pteronyssinus were the highest percentage (94. 27% ) among the inhaled allergens， and the orders of positive rates for other inhaled allergens were spring pollen assemblages (60. 64%)， summer and autumn pollen assemblages (53. 50%)， short ragweed (35. 29% )，fungal combination (30. 45% )，and dog dander (6. 75% ) . Conclusion The climate in Chengde area had its own special features. The dermatophagoides pteronyssinus，spring pollen assemblage and summer & autumn pollen assemblages are the most common inhalant allergens of allergic rhinitis in Chengde area. The patients with allergic rhinitis should try in particular to avoid them in their daily life.
