摘要: 死亡时间(postmortem interval,PMI)推断一直是法医学研究的重点与难点。机体死亡后,组织细胞发生自溶,核酸等大分子物质发生降解,其中DNA含量呈逐渐下降趋势,与PMI具有一定的线性关系,管家基因β-actin、GAPDH mRNA具有一定的稳定性,也可作为内参照进行PMI推测。本文综述了目前DNA、RNA以及蛋白质在PMI推断中的研究进展以及存在的问题,以期为法医学PMI的推断提供新的研究方向。

Abstract: Accurate estimation of postmortem interval(PMI) is one of the most important and difficult issues in forensic medicine. After death, the tissues autolyze and biomacromolecules degrade. DNA concentration decreases gradually with linear relationship with PMI. The housekeeping gene mRNA, for example β-actin, GAPDH, has certain stability and can be used to PMI estimation as internal standard. This paper reviews the research progress and problems about DNA, RNA and proteins in the estimation of PMI in order to provide guidance for forensic pathology.
