1、对过敏性疾病发病机制的几点新认识对过敏性疾病发病机制的几点新认识New understanding of the pathogenesis of allergic disease南京医科大学第一附属医院南京医科大学第一附属医院何韶衡何韶衡：过敏的发病率过敏的发病率1、占世界人口的、占世界人口的10%30%，而且正以每年大于，而且正以每年大于1%的速度的速度 增加，以儿童患者的发病率上升最为明显；增加，以儿童患者的发病率上升最为明显；2、发达国家比发展中国家多，城市比农村地区多，如、发达国家比发展中国家多，城市比农村地区多，如 1994年到年到2000年间，在意大利一家医院接受治疗的非年间，在意

2、大利一家医院接受治疗的非 欧洲人移民中，有欧洲人移民中，有84%在到欧洲前从没有过过敏症状；在到欧洲前从没有过过敏症状；3、随着生活水平的提高和环境的改善，我国近年来过敏性、随着生活水平的提高和环境的改善，我国近年来过敏性 疾病的发生率也有明显上升趋势；与城市化有关？疾病的发生率也有明显上升趋势；与城市化有关？4、我国儿童哮喘发病率比、我国儿童哮喘发病率比10年前明显增加，仅小儿哮喘患年前明显增加，仅小儿哮喘患 者达者达1000万之多，其中过敏为主要诱因。万之多，其中过敏为主要诱因。过敏反应发生过程示意图过敏反应发生过程示意图 第一部分第一部分:对肥大细胞在过敏性疾病对肥大细胞在过敏性疾病发病
