In criminal investigations, postmortem interval (PMI) is important information to be inferred in homicide investigations, as well as the focus and the difficulty in forensic pathology research. Because the DNA content in different tissues is relatively constant and shows changes regularly with the extension of PMI, it has become a research hotspot of PMI estimation. This paper reviews the recent progress of PMI estimation technologies including DNA-based single cell gel electrophoresis, image analysis, flow cytometry, real-time fluorescence quantitative PCR and high-throughput sequencing, hoping to provide references for forensic medicine practice and scientific research.

Scotland has a different legal system to that of England. This paper introduces a brief description of the legal system concerning the practice of forensic pathology and forensic medicine in Scotland. To aid understanding of forensic pathologic practice, the statistical analysis of post-mortem examinations at Glasgow, in 1998 is shown.

As times go by, the objects and subjects of researches have changed. Forensic medicine and science can not be escaped. To overview the international changes and trend of forensic medicine and science, we gathered abstracts of 3,354 articles from 5 outstanding international journals, those are (1) Forensic Science International, (2) Journal of Forensic Science, (3) American Journal of Forensic Medicine and Pathology, (4) Medicine, Science and the Law, (5) International Journal of Legal Medicine. There were 1,226 articles (36.6%) on forensic pathology, followed by forensic genetics (902 articles, 26.9%), toxicology (549 articles, 16.4%), forensic sciences (445 articles, 13.3%) and medical law & criminal psychology (232 articles, 6.9%). Corresponding authors from 4 countries (USA, Great Britain, Germany and Japan) took more than half of total corresponding authors. And there were 27 articles (0.8%) from Korea. This article will introduce us an overview of international trend of forensic researches.

Estimation of postmortem interval （PMI） is very important for judging the nature of cases, restricting the scope of investigation and suspect, which is always the emphasis and difficulty for forensic pathology. Early postmortem interval is the time between 0 and 24 hours after death. Due to the shorter time after the case occurred, precisely estimating early postmortem interval can help solve crimes, which has important significance in forensic medicine. In recent years, series of advanced methods and technologies are used to estimate the early PMI by the internal and overseas scholars who work in the forensic area. This paper reviews the research progress on fluids biochemistry, supravital reactions, metabolomics, imageology and the degradation rule of genetic material to provide a new idea to the study and application for estimation of early PMI.

OBJECTIVES: To survey the development status and actual needs of virtual autopsy technology in China and to clarify the applicability of forensic virtual autopsy laboratory accreditation. METHODS: The questionnaire was set up included three aspects：(1) the current status of virtual autopsy technology development; (2) the accreditation elements such as personnel, equipment, entrustment and acceptance, methods, environmental facilities; (3) the needs and suggestions of practicing institutions. A total of 130 forensic pathology institutions were surveyed by online participation through the Questionnaire Star platform. RESULTS: Among the 130 institutions, 43.08% were familiar with the characteristics of virtual autopsy technology, 35.38% conducted or received training in virtual autopsy, and 70.77% have establishment needs (including maintenance). Relevant elements were suitable for laboratory accreditation. CONCLUSIONS Virtual autopsy identification has gained social recognition. There is a demand for accreditation of forensic virtual autopsy laboratory. After the preliminary assessment, considering the characteristics and current situation of this technology, China National Accreditation Service for Conformity Assessment (CNAS) can first carry out the accreditation pilot of virtual autopsy project at large comprehensive forensic institutions with higher identification capability, and then CNAS can popularize the accreditation in a wide range when the conditions are suitable.

Investigation of the cause of death during diving is one of the contents of forensic pathology. In this article, relevant foreign literature is reviewed to summarize the techniques and methods used in the identification of diving deaths, such as accident reconstruction, diving monitoring data, postmortem CT examination and gas analysis (location and quantity) in the body of the corpse, in order to provide a reference for forensic identification of such cases.

In recent years, postmortem biochemistry analysis has gradually been applied to forensic practice, providing objective evidence for health conditions before death, disease pathophysiological processes and forensic diagnosis of postmortem interval and cause of death. It is of great significance to understand the change patterns of postmortem biochemical indicators and their applications in forensic medicine. This article reviews the research progress of postmortem biochemistry and its application in forensic medicine, it summarizes the existing problems of postmortem biochemistry analysis in forensic medicine of China and discusses the application prospect of postmortem biochemistry analysis in forensic medicine. This review is expected to provide references for forensic practitioners.

The Korean Society for Legal Medicine (KSLM) was founded in 1976 and launched its official journal, the Korean Journal of Legal Medicine (KJLM), in 1977. They have played an important role in Korea's forensic medicine and science, the demand for which has increased in Korean society over the years. A historical review is important and has a significant value in the advancement of forensic medicine and science in Korea. Accordingly, this study reviews and analyzes all papers published in KJLM for 39 years, from Volume 1, Issue No. 1 in 1977 to Volume 39, Issue No. 4 in 2015. There are 891 published papers, which are categorized into 318 review articles, 339 original articles, and 234 case reports. Of the total 891 papers, 377 (42.3%) are related to forensic pathology, whereas 111 (12.5%) concern forensic genetics. The major submitting institutes are forensic medicine departments of universities and the National Forensic Service. KJLM's history can be divided into two phases. The first phase is from the 1970s to the 1990s, and the second, from the 2000s to the present. Many review articles were published in the first phase; approximately 10% of these articles concern clinical forensic medicine and law. Articles on forensic genetics, identification, and entomology also started to be published in the first phase. In the next phase, many case reports from the National Forensic Service were published, and the number of articles on forensic pathology and forensic genetics multiplied. The results of this study provide KSLM and KJLM with direction toward sustainable development. This study is part of the organization's 40th anniversary celebration, and in commemoration of its contribution to advancing human rights and social stability in Korea.

OBJECTIVE: To evaluate the diversity of combined paternity index (CPI) of multiple STR loci when different population allele frequencies was used to calculate the paternity index. METHODS: CPI of 13 CODIS (combined DNA index system) loci for 108 trio cases and 108 duo cases selected randomly were calculated by using five Chinese Han population allele frequencies, respectively. RESULTS: The CPI range for trio cases and duo cases were 2077.63-50897711626.46 and 25.12-2998685141, respectively. When different population allele frequencies were applied to the same case, the ratio of maximum CPI and minimum CPI, which was more than 100, for trio cases and duo cases were 20 cases (19.52%) and 13 cases (12.04%), respectively. CONCLUSION The variation of CPI value of the CODIS loci was obvious with different allele frequencies. To prevent the error causing by uncertain allele frequencies, a conservative CPI value should be calculated in paternity testing.
