摘要:

文题释义:

文献计量学:是以文献体系和文献计量特征为研究对象,采用数学、统计学等计量研究方法,研究文献情报的分布结构、数量关系、变化规律和定量管理,进而探讨科学技术的某些结构、特征和规律的一门学科。主要应用于科学出版物评价、科研工作评价、学科发展评价、机构评价等。

CiteScore(CS):即Scopus数据库的核心指标,CS被定义为某期刊前3年发表的文献在统计当年被引用次数除以该刊前3年发表的文献数。CS和JCR中的核心指标影响因子(IF)是同类指标,都是某期刊一定引证时间窗口内论文的篇均被引频次。二者的主要区别有3个方面:①引证时间窗口不同:IF的引证时间窗口为2年,而CS为3年;②IF和CS的分子和分母所包含的文献类型不同:IF分子为期刊所有类型文献被引频次,分母仅计数可被引文献(论文和综述),而CS分母为期刊所有类型文献;③引证数据来源不同:计算IF所用的被引频次来源于WoS,而计算CS所用被引频次来源于Scopus。

背景:多能干细胞为许多疾病治疗带来了新的曙光,各国对该领域的投入和重视都在加强。

目的:为从事多能干细胞研究的中国机构或作者提供参考,促进该研究领域的质量提升与国际竞争力。

方法:利用Elsevier公司出版的Scopus数据库,使用关键词“pluripotent stem cell”OR“pluripotential stem cell”OR“multipotent stem cell”OR“multipotential stem cell”对2014至2018年发表的多能干细胞研究领域的文献进行了回顾性检索,并将检索得到的文献利用分析工具SciVaL和微软软件Excel2007做统计分析,揭示了全球文献产出学者、机构、高影响力论文以及中国的研究现状。

结果与结论:①2014至2018年Scopus数据库共收录多能干细胞研究领域文献18 508篇,领域加权影响因子为1.43,其中医学学科产出6 398篇,领域加权影响因子为1.38,27.7%的文章处于高被引地位,48.4%的文章发表在高影响力期刊上,27%的文献是国际合作完成;②发文量最多的机构是哈佛大学805篇,共有1 732位作者,总被引21 654次。中国科学院发文量排在第4位,一共发表394篇,1 139位作者,总被引5 313次;③发文量最多的个人是来自斯坦福大学的JOSEPH教授117篇,总被引2 878次,H指数74;④5篇被引大于500的论文中,有2篇是综述文献,3篇研究论文;日本有6个机构进入亚洲机构前10位,中国紧随其后有3个,印度1个;中国发文最多的作者是裴端卿教授45篇,总被引864次;⑤结果表明,2014至2018年美国哈佛大学处于领先地位,其产出和影响力都显著,在全球发文最多的10名学者中美国和日本各占3席,德国占据2席,中国在该领域有影响力的学者或机构还有待努力。通过综合分析高影响力研究机构、研究作者、研究文章,为多能干细胞领域的科学研究提供前瞻性思考。

Abstract:

BACKGROUND: Pluripotent stem cells have brought a new light for treating many diseases, and countries are increasing their investment and attention in this field.

OBJECTIVE: To provide reference for Chinese institutions or authors engaged in pluripotent stem cells, so as to promote the quality and international competitiveness in this research field.

METHODS: A retrospective retrieval was performed using the keywords “pluripotent stem cell” OR “pluripotential stem cell” OR “multipotent stem cell” OR “multipotential stem cell” for the articles concerning pluripotent stem cells published from 2014 to 2018 in the Scopus database published by Elsevier. The retrieved articles were analyzed by using SciVaL and Microsoft Excel 2007. It revealed the scholars and institutions of the articles, high-impact papers and research status in China.

RESULTS AND CONCLUSION: (1) From 2014 to 2018, the Scopus database contains a total of 18 508 articles addressing pluripotent stem cells. Its Field-Weighted Impact Factor is 1.43, its medical discipline output is 6 398, and its Field-Weighted Citation Impact is 1.38. 27.7% of the articles are highly cited, 48.4% of the articles are published in highly influential journals, and 27% of the articles are completed by international cooperation. (2) The institution with the largest number of publications is 805 articles at Harvard University, with a total of 1 732 authors and a total of 21 654 citations. The Chinese Academy of Sciences ranks fourth in terms of volume, publishing 394 articles and 1 139 authors, with a total of 5 313 citations. (3) The most published individual was Professor JOSEPH from Stanford University, 117 articles, total cited 2 878 times, H-index 74. (4) Of the 5 papers cited greater than 500 times, 2 are reviews and 3 original researches. Six Japanese institutions are in the top 10 in Asia, followed by three in China and one in India. The author of the most published articles in China is Professor Pei Duanqing, who has published 45 articles with a total of 864 citations. (5) In summary, in 2014-2018, Harvard University in the United States takes the lead, with evident output and influence. The United States and Japan each account for 3 of the top 10 scholars and Germany holds two, while Chinese influential scholars or institutions in the field have yet to work. Comprehensive analysis of high-impact research institutions, research authors, and research articles provides forward-looking thinking for scientific research in the field of pluripotent stem cells.
