OBJECTIVES: To understand the legal application and case deposition of assessment opinions of sexual self-defense capability, and to explore the necessity of legal correspondence in the sexual defense capability assessment. METHODS: According to the self-made questionnaire, the cases of sexual self-defense capability assessment completed by the Academy of Forensic Science from January 1, 2012 to December 31, 2018 were statistically analyzed through telephone interviews and referrals. RESULTS: Among the 69 cases, 3 cases (4.3%) had complete sexual self-defense capability, 30 cases (43.5%) had weakened sexual self-defense capability, 32 cases (46.2%) had no sexual self-defense capability, and 4 cases (5.8%) were not suitable for assessment. Among the 30 cases with weakened sexual self-defense ability, 15 cases were filed and investigated by public security authorities for rape and 15 cases were not. The inconsistent rate of disposition was 1∶1. Among the 15 rape cases filed and investigated by the public security authorities, 10 cases were arrested and prosecuted by the procuratorate and sentenced to fixed-term imprisonment by the court, while the other 5 cases were not arrested and prosecuted by the procuratorate, with an inconsistent rate of disposition being 2∶1. CONCLUSIONS The legal application of the assessment opinion on the weakening of sexual self-defense capability is inconsistent, and the judicial disposition is confusing. It is imperative to unify and correspond the classification of sexual self-defense capability with the legal requirements.

OBJECTIVES: To analyze the literature on forensic sciences indexed in Science Citation Index Expanded （SCIE） in recent 10 years, and to understand the research status, characteristics and trends in the field of forensic sciences. METHODS: Literature on forensic sciences from 2008 to 2017 in Web of Science （WoS） was retrieved. The documents number and geographical distribution, document types, source titles, organizations, research areas, authors, funding agencies, and the high cited articles were detected. The impact factors （IF） of journals were retrieved in Journal Citation Reports （JCR）. The data were analyzed with descriptive statistics. RESULTS: From 2008 to 2017, there were 21 001 documents on forensic sciences in SCIE. The main document type was articles, with English as the major language. With regards to research areas, pathology has the largest number of papers worldwide, and genetics and heredity has the largest number of publications in mainland China. Among the 18 journals where the documents was published, Forensic Science International ranks the first on publication count, and Forensic Science International Genetics has the highest IF （5.637） in the JCR 2017. In 2017, the number of papers from mainland China increased by 48.50% compared with 2016, which was higher than the global increase （32.63%） and the top-5 countries in terms of number of publications （the US, Germany, the UK, Australia, Italy）. The average document count per organization is 1.98 worldwide and 1.17 in mainland China, respectively. The publication number per author is 0.53 worldwide and 0.36 in mainland China, respectively. Around 28.17% of the publications were funded, with National Natural Science Foundation of China （NSFC） as the Top 1 funding agency （192 papers）. Among the documents with citations, the most cited publication has been cited for 366 times. CONCLUSIONS The yearly numbers of publications on forensic sciences are increasing during recent 10 years. Focusing on the mainland China, there would be more high-quality papers with the steady funding of NSFC.

Forensic palynology is to apply palynology to the field of forensic science, using pollen and spores to solve issues in juridical practice, such as civil and criminal issues. Sporopollens have a small size, wide distribution, diverse morphology, can be easily transferred, have durability, and is not easily noticed. It can provide strong investigation and related evidence for case detection as good trace evidence. The application of palynology in forensic science has achieved certain success, but it is underutilized in most countries. This paper analyzes the evidence value provided by sporopollen, collection of the sporopollen samples, the progress in detection technology and challenges ahead, based on the biological characteristics of sporopollen, combined with recent successful cases in forensic science, to comprehensively discuss the research progress in forensic palynology and its application prospects in forensic science.

The forensic medicine department of the National Institute of Scientific Investigation (NISI) designed a form of forensic laboratory information sheet for autopsy practice in 2006. The forensic laboratory information sheet consists of three parts of checklist; the first part concerns death circumstance-related investigatory facts, the second part displays a table of checklist regarding types of forensic scientific tests to be done, and the third describes brief presumptive results of forensic autopsy. This laboratory information sheet reminds forensic pathologists and other forensic medicine staffs to perform appropriate tissue sampling, helps reduce the probability of errors during interdepartmental flow of sampled tissues, and contributes to produce better forensic science results on the basis of good communication. We suggest that this communication form between forensic medicine and science departments should be now considered efficient and actuated especially in areas outside NISI.

Objective To analyze the forensic science-related literature included in the Web of Science database in the recent decade through bibliometric methods, to provide reference for relevant research. Methods Literatures were searched in 3 ways： Subject search, Journal search and Institution search. The annual distribution, national （regional） distribution, institution distribution, journal distribution and the research hotspots of the related literatures were analyzed through Thomson Data Analyzer （TDA）, Ucinet, VOSviewer, and so on. Results A total of 49 469 related literatures were included in the recent decade. The number of literatures continued to climb year by year. The top 15 countries （regions） accounted for 78.52% of the total number of published literatures, and China ranked 5th, but ranked 12th in terms of the proportion of high-cited papers; Netherlands, Switzerland, Australia, etc. had high comprehensive influence. The number of countries （regions） that cooperated with China were 129, including the United States, the United Kingdom and Germany. The Institute of Forensic Science of Saint Mary's University, University of Sydney and Netherlands Forensic Institute had high comprehensive influence, and the related literatures were published on 6 357 journals. According to high-frequency co-occurrence network and high-cited papers, brain injury, health policy, assessment scales and models and medical imaging were selected as research hotspots. Conclusion The total number of literatures in forensic science included in international SCI increased significantly, and the influence of China's achievements needs to be greatly enhanced; the research institutions were scattered, and China's research power needs to be continuously condensed; the research hotspots in international fields are extensive, and the international participation of China in top level research needs to be strengthened.
