摘　　要：精阴混合斑是性侵案件的重要检材,也是法医物证学检验的重点。分离提取到精子细胞DNA并与犯罪嫌疑人进行检验鉴定,对认定或排除犯罪嫌疑人以及案件侦破起着关键作用。为满足DNA检验需要、解决实际案件中的具体问题和困难,多年来国内外法医工作者尝试建立了多种精阴混合斑的分离检验方法。本文从细胞和DNA两个层面对有关方法就其核心内容和优缺点以及适用性等进行综述,着重阐述近年来国内外新的研究进展,并结合实际应用价值和前景做总结与展望。The mixed stain of seminal and vaginal fl uid is one of the important evidential materials in sexual assault cases,a crucial item in forensic biological examination, too. The vital role will be played when the sperm cell DNA is separated and extracted from the mixed stain and matched to the criminal suspect, resulting in the identifi cation or exclusion of criminal suspects and successful unravelment of the involving case. Forensic scientists have until present established a variety of methods for separating sperm DNA from the mixed stains in their endeavor to meet the requirements of DNA detection and solve the specifi c problems and diffi culties from actual cases. This review summarizes the relevant methods at the two levels of cell and DNA about their core gists, advantages, disadvantages and applicability, focusing on the new research progress home and abroad in recent years and carrying out overview and prospect with combination into the practical forensic applicability and developability.
