心源性猝死的法医鉴定文献计量学分析

Bibliometric Analysis of Medicolegal Identification of Sudden Cardiac Death

目的对近35年来中国知网(CNKI)收录的关于心源性猝死的法医鉴定文献中的研究状况及发展趋势进行分析。方法检索1981～2016年CNKI收录的关于心源性猝死的法医鉴定文献,并对其进行描述性统计分析。结果截止2016年9月,共检索文献559篇,纳入546篇。2000年以后的文献发表数量显著增加;作者所在机构多为国内各大高校及其科研院所,共发表文献520篇;获各级基金资助的文献有100篇,占总文献数的18.32%;以基础研究为主,占58.98%;被引用频次占38.1%,总体偏低;触及高频关键词40个,使用频次居前五位的是"法医病理学""猝死""心源性猝死""心脏""免疫组织化学"。结论自1981年以来,心源性猝死的法医鉴定文献数量呈现逐年增加,但其多为基础研究,研究因子较为受限。建议加强实用性研究,探索更多研究方法来促进心源性猝死的法医鉴定研究。

Objective To analyze the literature about medicolegal identification of sudden cardiac death during 1981 to 2016 from CNKI database,and to explore the trend of relevant researches and development.Methods CNKI database was selected as the data source,and the statistical analysis was carried out from the perspective of bibliometrics.Results As of September 2016,totaling 559 articles were searched and 546 ones were enclosed for this analysis.The number of published articles had been significantly increasing after 2000.The authors of the published literature are mostly from domestic universities and institutes,having published 520 articles.There are 100 articles that were supported by the funds of various levels,accounting for 18.32%of the total enclosed literature.Those articles mainly involving with basic research take up about 58.98%.The collective citation is around 38.1%,with 338 articles cited none.40 frequency-high keywords were hit for 40,693 times,making the top five been as“forensic pathology”,“sudden death”,“sudden cardiac death”,“heart”and“immunohistochemistry”.Conclusion The number of articles about research on medicolegal identification of sudden cardiac death had been yearly increasing since 1981,with more attention being paid into basic research.However,such researches are limited of influential impact.Therefore,the practical researches and methods should be strengthened and explored more.
