目的:通过对1995年以来我室诊断为唐氏综合征(D ow n syndrom e D ow n综合征)患儿的细胞遗传学研究,探讨减少D ow n综合征患儿出生的优生对策。方法:外周血淋巴细胞培养,染色体核型分析;进行遗传咨询,确定优生对策。结果:染色体检查55例,43例为D ow n综合征核型。结论:进行细胞遗传学检查对临床确诊D ow n综合征患儿是非常必要的,特别是1岁以内的婴儿;根据发生因素,制定相应的优生对策,避免不良因素侵袭,是减少唐氏综合征患儿出生的必要手段之一。
OBJECTIVE: To investigate the eugenics strategies to reduce the birth of children with D ow n syndrome by analyzing the cytogenetics of children with D ow n syndrom e D ow n syndrome in our hospital since 1995. Methods: Peripheral blood lymphocyte culture, chromosome karyotype analysis; Genetic counseling to determine eugenics. Results: 55 cases of chromosomal examination, 43 cases of D ow n syndrome karyotype. Conclusion: The cytogenetic examination is very necessary for clinical diagnosis of D ow n syndrome in children, especially infants less than 1 year old; according to the occurrence factors, the corresponding eugenics strategies are formulated to avoid the invasion of adverse factors, which is to reduce Down’s syndrome One of the necessary means of giving birth to children.
