近年来,血友病甲的诊治取得显著成就,使用因子Ⅷ制剂和其他方法明显降低儿童死亡率,并延长患者的生存期。患者的寿命几乎同正常人相等,结婚和生育子女,故在人群中造成病理性基因的积累.从医学遗传和社会的观点看,对血友病基因预防具有特殊的意义。 In recent years, the diagnosis and treatment of hemophilia A has made remarkable achievements, the use of factor Ⅷ preparations and other methods significantly reduce child mortality and extend patient survival. Patients have almost the same life expectancy as their normal counterparts, marry and have their children, and thus cause the accumulation of pathological genes in the population, which is of special significance for the prevention of hemophilia genes from the point of view of medical genetics and society.
