Research Progress on Age Estimation Based on DNA Methylation / 法医学杂志

Age estimation is of great significance in the fields of criminal investigation and forensic identification. It can provide the age information of individuals to judicial departments to facilitate the development of judicial work. In recent years, age estimation methods expanded from the morphological level to the molecular biology level. With the rapid development of epigenetics represented by DNA methylation, and the advancement of DNA methylation detection technology together with the detection platform, many age estimation methods based on DNA methylation biomarkers, or using several biological fluids, such as blood, blood stains, saliva, semen stains, etc. are developed. Currently, researches related to age estimation based on DNA methylation are relatively widely carried out. This paper summarizes the researches on age estimation based on DNA methylation, in order to provide references for related studies and forensic applications.

Brief discussion on the proof standard of traditional evidence of forensic pathology in murder cases / 复旦学报（医学版）

Objective In the legal proceedings of murder cases,we often encounter the problem of proof standard in traditional forensic pathology in deep research,which is lack of systemic discussion in domestic academic field.This paper aimed to discuss this problem.Methods We compared the relevant characteristics of different legal systems on the standard of proof system,analyzed the elements of the forensic pathology evidence related to murder cases,and discussed the problem with the author's judicial practice experience.Results We believe that the cause of death,death time,injury and injury tools are the three most important forensic pathology evidences in the murder of the standard system as the "three pillars".Conclusions Division of standards in traditional forensic pathology evidence in the murder is of great significance to raise the sense of evidence of forensic medicine,and if it exists major flaws in the evidence of forensic pathology,the evidence can be corrected or the proceedings can be terminated at the very beginning of the litigation phase,which is of great value to the savings of judicial resources.

Costicartilage analysis inspection technology in the application of forensic medicine / 法医学杂志

The traditional costicartilage analysis inspection is limited to morphological inspection. In recent years, with the development of forensic radiology and molecular genetics, the costicartilage analysis inspection technology has been further enriched and developed. At present, the costicartilage analysis inspection technology have been able to be used in the practice of forensic medicine. This paper reviews the research advances about the costicartilage analysis inspection technology in the identification of human gender, age and so on in order to provide the references for forensic appraisers.
