基于CiteSpace的急性肾损伤的文献计量与可视化分析

Bibliometric and visualization analysis of acute kidney injury based on CiteSpace

目的 对急性肾损伤的研究现状、趋势及热点进行可视化分析。方法 收集中国知网、Web of Science核心合集数据库中关于急性肾损伤的相关文献,搜索时间为2012年1月至2021年12月。使用Cite Space 6.2.R3软件对国家、作者、关键词等进行可视化分析。结果 中文文献发文量处于平稳状态,英文文献发文量急速上升。相关研究主要集中在美国、中国、德国。中文文献发文量前三位的作者为丁小强、梁馨苓、倪兆慧,英文文献发文量前三位的作者为Ronco C、Kellum JA、Bellomo R。中文文献中高频关键词前三位为脓毒症、危险因素、预后,共形成11个聚类,突现词有心力衰竭、线粒体等。英文文献高频关键词前三位为mortality、outcome、disease,共形成8个聚类,突现词有infection、care等。结论 国外急性肾损伤的发展较迅速;急性肾损伤的病因、发病机制、替代治疗、预后为研究热点;研究前沿为保护、预测模型、液体复苏等方面。

Objective To visually analyze the research status,trend,and hotspots of acute kidney injury.Methods The relevant literatures on acute kidney injury from CNKI and Web of Science core collection database were collected,the search was conducted from January 2012 to December 2021.The country,author,and keywords were visually analyzed by CiteSpace 6.2.R3 software.Results The number of published Chinese literature was stable,while the number of published English literature was rising rapidly.Relevant studies were mainly concentrated in the United States,China,and Germany.Ding Xiaoqiang,Liang Xinling,and Ni Zhaohui were the top three authors in Chinese literature,while Ronco C,Kellum JA,and Bellomo R were the top three authors in English literature.The top three high-frequency keywords in Chinese literature were sepsis,risk factors,and prognosis,forming a total of 11 clusters,and the breakout words were heart failure,mitochondria,etc.The top three high-frequency keywords in English literature were mortality,outcome,and disease,which formed a total of 8 clusters,and the emergent words were infection,care and so on.Conclusion Acute kidney injury develops rapidly in foreign countries,the etiology,pathogenesis,alternative therapy,and prognosis of acute kidney injury are the hot spots of research,and the frontiers of research are protection,predictive model,fluid resuscitation and so on.
