目的:对比多重连接探针扩增(multiplex ligation-dependent probe amplification,MLPA)与染色体核型分析技术,明确两种技术在流产绒毛样本检测中的效能,以期建立最优化的实验室检测方案。方法采集189例稽留流产绒毛样本,同步行 MLPA (SALSA P290-B1)和常规染色体核型分析检测,并对检测结果进行统计分析。结果两种方法综合分析成功187例,占98.94%。其中核型分析成功117例,占61.90%;MLPA 能够检测185例,占97.88%。核型分析与 MLPA 结论一致70例,占37.04%;42例多倍体或非探针目标区染色体异常,MLPA未能检出,占其独立检测样本的22.70%(42/185);72例因培养失败等因素未能成功核型分析,占38.10%。结论①独立采用核型分析或 MLPA技术均不能有效实现流产绒毛染色体异常的检测分析。②综合考虑检测成本和效能,先行染色体核型分析并同时留取流产绒毛样本,应用 MLPA作为核型分析失败的补充方案具有临床可行性。
目的:對比多重連接探針擴增(multiplex ligation-dependent probe amplification,MLPA)與染色體覈型分析技術,明確兩種技術在流產絨毛樣本檢測中的效能,以期建立最優化的實驗室檢測方案。方法採集189例稽留流產絨毛樣本,同步行 MLPA (SALSA P290-B1)和常規染色體覈型分析檢測,併對檢測結果進行統計分析。結果兩種方法綜閤分析成功187例,佔98.94%。其中覈型分析成功117例,佔61.90%;MLPA 能夠檢測185例,佔97.88%。覈型分析與 MLPA 結論一緻70例,佔37.04%;42例多倍體或非探針目標區染色體異常,MLPA未能檢齣,佔其獨立檢測樣本的22.70%(42/185);72例因培養失敗等因素未能成功覈型分析,佔38.10%。結論①獨立採用覈型分析或 MLPA技術均不能有效實現流產絨毛染色體異常的檢測分析。②綜閤攷慮檢測成本和效能,先行染色體覈型分析併同時留取流產絨毛樣本,應用 MLPA作為覈型分析失敗的補充方案具有臨床可行性。

Objective To establish optimized laboratory testing proposal through comparison of multi-plex ligation-dependent probe amplification (MLPA)and conventional karyotyping for the diagnosis of pregnancy loss.Method A cohort of 189 patients underwent side-by-side analysis of chorionic villi sam-ples by both conventional karyotyping and MLPA (SALSA P290-B1 )with direct comparison of results. Results 187 samples (98.94%)were analyzed successfully by conventional karyotyping and MLPA.117 samples (61.90%)were analyzed successfully only by karyotyping and 185 samples (97.88%)were ana-lyzed only by MLPA.70 samples (37.03%)yielded the same findings with both MLPA and cytogenetic results.42 samples (22.70% in the MLPA alone samples)were not detected because of inability to char-acterize structural rearrangements or ploidy changes.72 samples (38.10%)had no cytogenetic results due to culture failures where MLPA results were available.Conclusions ①Chromosomal abnormalities can’t be detected effectively in single method whether MLPA or conventional karyotyping.②Considering the cost and efficiency,the optimal situation would be to have MLPA available in the laboratory as the comple-mentary examination of the conventional karyotyping.
