孕妇外周血中游离胎儿DNA富集与分离方法及在无创性产前诊断中的应用
Zhongguo shiyan zhenduanxue, 2014 在我国,每年新生儿出生缺陷多达80万至120万,尽早进行产检筛查和诊断是最有效的应对措施,然而目前常规的诊断方法皆为有创性方法,对胎儿和孕妇都有一定的危险性,因此发展新的无创性产前诊断具有重要的临床意义。1997年Lo等[1]发现在孕妇血浆中存在着少量的游离胎儿DNA（Cellfree20fetal20DNA,cffDNA）,为无创性产前诊断方法提供了新的途径。孕妇从怀孕第7周开始即可检测到cffDNA ...

磁性纳米复合粒子富集胎儿细胞在无创性产前诊断22q11.2微缺失综合征中的应用
Zhongguo shiyan zhenduanxue, 2011 目的探讨利用磁性纳米复合粒子富集胎儿细胞进行无创性产前诊断22q11.2微缺失综合征的可行性。方法收集研究对象26例,分别经过磁性纳米粒子富集胎儿有核红细胞（研究组）及羊水穿刺胎儿细胞（对照组）进行荧光原位杂交（FISH）检测确定22q11.2是否存在异常,比较两组之间存在的差异。结果两组在诊断22q11.2微缺失综合征方面一致率为100%（2/2）,证实了利用该方法实现无创性产前诊断22q11.2微缺失综合征的可行性。结论磁性纳米复合粒子富集胎儿细胞诊断22q11.2微缺失综合征为无创性的产前诊断 ...
