基于Web of Science对运动干预肠道菌群研究的可视化分析

Visualization Analysis of Exercise Interventions in Gut Microbiota Based on Web of Science

目的:分析运动干预肠道菌群的研究现状、研究主题及前沿热点,以期为该领域的科研人员提供研究方向和思路。方法:采用文献分析软件Cite Space,对Web of Science核心合集数据库收录的以"肠道菌群"、"运动"为关键词的1258篇文献进行知识图谱分析。结果:研究力量以美国、中国为主,但中国的中心性较小,国际间影响力相对较低;国内外相关文献最早开始出现于1994年,发表量自2000年起基本呈现逐年增多的趋势,2017~2020年增长幅度较大;目前该领域已形成核心团队,O’Sullivan O和Huang CC分别发表了15、13篇文献;出现频率较高的关键词为肥胖、饮食、炎症;Harvard University是发表相关研究最多的机构;NUTRIENTS是发表相关研究最多的期刊,PLOS ONE发文量位居第二但被引频次最高,达852次;主要研究资金来源于美国,中国位居第二。结论:基于肠道菌群的运动干预研究属于新兴话题,该领域目前研究方向虽多,但各方向文献量较少,表现出研究力量分散的特点。另外,我国在该领域文献发表量多但影响力较小,尚缺乏国际间合作。

Objective: To analyze the research status, research topics and frontier hot spots of exercise intervention gut microbiota, with a view to providing research directions and ideas for researchers in this field. Methods: The bibliometric analysis software Cite Space was used to analyze the knowledge graph of 1258 literatures with "gut microbiota" and "exercise" as the key words in the Science Citation Index Expanded(SCI-E) of Web of Science. Results: The research power is dominated by the United States and China, but China is less central and has relatively low international influence. Relevant literatures at home and abroad first appeared in 1994, and the number of publications has basically increased year by year since2000, with a large increase from 2017 to 2020. At present, several core teams have been formed in this field and O’Sullivan O and Huang CC have published 15 and 13 literatures respectively. The most frequent keywords were obesity, diet, and inflammation. Harvard University published the most related research institutions. NUTRIENTS is the journal with the most published research, while PLOS ONE is the second journal with the highest citation frequency(852 times). The main funding comes from the United States, with China ranking second. Conclusion: Research on exercise intervention based on gut microbiota is an emerging topic. Although there are many research directions in this field at present, the literature in each direction is small, showing the characteristics of scattered research forces. In addition, China has published large number of literatures in this field, but its influence is small, and there is still a lack of international cooperation.
