Abstract:

目的探讨宁夏人群环氧化酶-2(COX-2)基因-1195位点基因型和等位基因频率在汉、回民族和男、女性别间的分布特点。方法通过聚合酶链反应-限制性片段长度多态性(PCR-RFLP)技术对398例汉族和370例回族健康人群COX-2基因-1195G>A单核苷酸多态性位点进行检测。结果COX-2-1195G>A基因型GG、GA、AA和等位基因G、A的分布频率在宁夏汉族人群中是14.57%、69.35%、16.08%和49.25%、50.75%,在回族人群中是9.73%、77.84%、12.43%和48.65%、51.35%,宁夏回族人群COX-2-1195GA基因型频率高于汉族(P=0.025);在宁夏男性人群中是10.76%、74.02%、15.22%和47.77%、52.23%,在女性人群中是13.70%、72.87%、13.43%和50.13%、49.87%,男、女性别间基因型和等位基因频率分布差异无统计学意义(P>0.05)。结论宁夏回族人群携带COX-2-1195GA基因型频率多于汉族;COX-2-1195G>A基因型和等位基因频率在宁夏男、女性别间分布无统计学意义。
