基于Scopus的生物可降解金属材料文献调研与分析

Investigation and Analysis on the Literatures of Biodegradable Metal MaterialsBased on Scopus

利用文献计量学方法和可视化分析工具,介绍生物可降解金属材料的研究概况和现状,为生物可降解金属材料的发展提供参考。基于Scopus数据库,检索时间截止到2018年:首先从宏观的角度统计分析学术产出情况、发展变化趋势,以及文献类型分布;其次选取2014—2018年的相关文献,分析被引用次数TOP10国家、TOP10机构和TOP10学者情况;然后利用CiteSpace.5.5.R2对2014—2018年发表的相关文献进行作者合作网、机构合作网分析;最后使用Scival对2014—2018年发表的相关文献进行关键词分析。结果发现,近五年(2014—2018年)相关文献被引用次数最多的国家是中国,被引用次数最多的机构是北京大学,被引用次数最多的学者是北京大学的郑玉峰。以北京大学郑玉峰等学者为核心的科研团队构成了最大的作者合作子网;以北京大学为核心的科研团队和中国科学院为核心的科研团队构成了相对较大的两个机构合作子网。目前研究较多的生物可降解金属材料有镁、镁合金、钛、钛合金等;研究生物可降解金属材料的三种性能:生物相容性、可降解性/耐腐蚀性、力学性能/机械性能;生物可降解金属材料主要应用于医学方面,比如骨修复、牙修复、支架等。作为一个发展阶段的研究领域,生物相容性、可降解性/耐腐蚀性、力学性能/机械性能的最佳状态是研究的重点和方向,是判断生物可降解金属材料是否适合植入人体的标准。

By using bibliometrics and visual analysis tools,this paper introduces the research situation of biodegradable metal materials,and provides reference for the development of biodegradable metal materials.Based on the Scopus database,the retrieval time is up to 2018:firstly,from a macro perspective,statistical analysis of academic outputs and development trends,as well as the distribution of literature types;secondly,relevant literatures from 2014 to 2018 were selected to analyze the citation times of top 10 countries,top 10 institutions and top 10 scholars;then,CiteSpace.5.5.R2 was used to analyze the authors’and institutions’cooperation networks on the relevant literatures published in 2014—2018;finally,Scival was used to analyze the key words of relevant literatures published in 2014—2018.In the past five years(2014—2018),the most cited country is China,the most cited institution is Peking University,and the most cited scholars is Zheng Yufeng of Peking University.The research team with Zheng Yufeng from Peking University and other scholars as the core constitutes the largest author cooperation subnet;the research team with Peking University as the core and the research team with Chinese Academy of Sciences as the core constitute two relatively large institution cooperation subnets.At present,many biodegradable metal materials are studied,such as magnesium,magnesium alloy,titanium,titanium alloy,etc.;three properties of biodegradable metal materials are studied:biocompatibility,degradability/corrosion resistance,mechanical properties;biodegradable metal materials are mainly used in medical aspects,such as bone repair,tooth repair,stent,etc.As a research field in the development stage,the best state of biocompatibility,degradability/corrosion resistance,mechanical properties is the focus and direction of the research,which is the judgment standard of whether biodegradable metal materials are suitable for implantation into human body.
