目的探讨不良孕产史与细胞遗传学的关系。方法对137对有不良孕产史的夫妇进行外周血淋巴细胞染色体核型分析。结果发现20例异常核型,异常检出率为7.30%。其中结构异常7例,数目异常5例,Y染色体长度变异7例,另有1例性分化异常。结论不良孕产史夫妇染色体核型异常发生率明显偏高,对其行细胞遗传学分析很有必要,可为临床病因诊断提供依据。
Objective To investigate the relationship between poor pregnancy history and cytogenetics. Methods Chromatin karyotypes of peripheral blood lymphocytes were analyzed in 137 pairs of couples with bad history of pregnancy and childbirth. The results showed that 20 cases of abnormal karyotype, the abnormal detection rate was 7.30%. Among them, there were 7 cases of structural abnormalities, 5 cases of abnormal number, 7 cases of Y chromosome length variation, and 1 case of abnormal differentiation. Conclusion The incidence of abnormal karyotype in couples with unhealthy pregnancy is obviously high, which is necessary for cytogenetic analysis. It may provide evidence for the diagnosis of clinical etiology.
