近年来随着医学遗传学的发展,了解到先天畸形、单基因遗传病和染色体异常是新生儿死亡和疾患的重要原因,也是儿童和青少年疾病和死亡的因素。同时这种患儿给家庭和社会,不论在经济上、精神上都带来沉重的负担。开展遗传咨询,产前诊断和选择性流产的新优生学是预防遗传性疾病的有效方法。近十年来国内、外都开展了羊水内胎儿脱落细胞的培养,进行产前诊断,以了解胎儿的染色体核型分析和生化测定,发现异常及时引产,这样就可以减少遗传病和先天畸形儿的出生。开展此项工作的关键在于羊水细
In recent years, with the development of medical genetics, it is understood that congenital malformations, single-gene inherited diseases and chromosomal abnormalities are important causes of neonatal death and illness, and are also factors of diseases and deaths of children and adolescents. At the same time, this type of childbirth imposes a heavy burden on families and society, both financially and mentally. New eugenics for genetic counseling, prenatal diagnosis and selective abortion are effective methods of preventing genetic diseases. Nearly a decade, both at home and abroad were carried out amniotic fluid cells within the fetal cells for prenatal diagnosis to understand the fetal chromosomal karyotype analysis and biochemical determination of abnormal and timely induction of labor, so that genetic diseases and congenital malformations can be reduced children Born The key to carry out this work is fine amniotic fluid
