摘要 目的应用荧光原位杂交(FISH)技术检测早期自然流产胚胎染色体数目异常,以期发现经典的细胞遗传学方法可能遗漏的信息,探讨荧光原位杂交(FISH)技术用于诊断绒毛间期细胞染色体数目异常的临床应用价值。方法采用FISH技术对我院200例50-84天的自然流产胚胎的绒毛进行7条染色体数目(13、16、18、21、22、X和Y)的快速检测。同时,将绒毛接种、培养,进行常规细胞染色体核型分析,作为FISH检测结果的对照。结果被检测的200例样本中,用FISH检测,均获得诊断结果,检测成功率为100%,而常规细胞染色体核型分析,则只有169例获得诊断结果,检测成功率为84.5%。除一例染色体结构异常的标本FISH未检测出来外,余下标本,FISH检测结果与常规细胞染色体核型分析结果均相符合。结论 FISH技术与传统的绒毛细胞培养染色体核型分析相比,过程迅速,方法简单,提高了诊断的成功率,但无法完全取代传统的染色体核型分析,应将两者结合应用于临床。
