Abstract： 目的探讨β2-肾上腺素能受体(β2- AR)基因16、27位点多态性与支气管哮喘的相关性.方法采用等位基因特异性聚合酶链反应方法,对74例支气管哮喘者进行β2-AR基因多态性分析,并与43例肺炎患者、39名健康者对照.结果①两对照组β2-AR基因16、27位点多态性分布无差异性;②支气管哮喘组β2-AR基因16位点分布频率:精氨酸/甘氨酸占47.2%,甘氨酸/甘氨酸占35.2%,与两对照组比较(p<0.05);27位点分布频率:谷氨酰胺/谷氨酰胺占33.7%,谷氨酰胺/谷氨酸占52.7%,谷氨酸/谷氨酸占13.6 %,与两对照组比较(p>0.05).结论支气管哮喘的发生与β2-AR基因16位点多态性相关联,与27位点多态性不相关.
