高血压与肠道菌群相关性研究文献计量学分析

Bibliometric Analysis of the Correlation between Hypertension and Gut Microbiota

目的分析评价2008—2017年SCI收录的高血压与肠道菌群相关性研究的文献情况,为进一步开展该领域的研究提供参考。方法以Web of Science核心合集数据库为资料来源,选用Web of Science核心合集数据库中的高级检索,分别对高血压(hypertension)和肠道菌群(gut microbiota)的同义词、上下位类主题词采用布尔运算符"OR"组配,组间采用"AND"组配,字段标识符选择主题(TS);检索年限:2008—2017年;检索日期:2017-11-01;对高血压与肠道菌群相关性研究文献资料进行描述性统计分析。结果共纳入62篇文献。发文量从2015年开始逐年增多;Current Hypertension Reports发文最多(5篇);Circulation的影响因子最高(19.309);高被引文献(被引量≥9.02)有14篇;文献合作度7.29,文献合作率91.94%;发文量≥2篇的作者主要来自美国;有科研基金资助的文献48篇(77.42%);本研究共涉及88个关键词,研究方向以心血管系统与心脏病学为主,研究内容主要集中于肠道菌群失调与高血压的相关性。结论高血压与肠道菌群的相关性研究目前尚处于起步阶段,存在发文期刊分散、学术影响力小等不足,需对二者的因果关系、作用机制等关键问题继续探索、验证,在研究内容和研究质量上不断丰富和优化。

Objective To analyze and evaluate the literature on the correlation between hypertension and gut microbiota collected in SCI from 2008 to 2017,and to provide a reference for further research in this field.Methods The Web of Science Core Collection Databases were used as the data source,and the"Advanced Search"feature was used to retrieve the related literature.The synonym and hyponym or hypernym keywords related to"hypertension"and"gut microbiota"combined with the Boolean operator"OR",or the Boolean operator"AND"were used in the search,and"Topic"(TS)was chosen as the field tag.The searching period was 2008-2017,and the searching date was 2017-11-01.A descriptive statistical analysis was conducted on the literature on the correlation between hypertension and gut microbiota.Results A total of 62 papers were included.The number of published papers increased from 2015;the journal Current Hypertension Reports published the highest number(five papers),and Circulation had the highest impact index(19.309).There were 14 highly cited papers(cited≥9.02).The degree of literature cooperation was 7.29,and the rate of literature cooperation was 91.94%.Authors who had two or more papers were mainly from the United States.There were 48 papers sponsored by funds(77.42%).The present study used 88 keywords.The research fields were primarily the cardiovascular system and cardiology,and the research content mainly focused on the relationship between intestinal dysbacteriosis and hypertension.Conclusion Research on the correlation between hypertension and gut microbiota is still in an early stage.There are some shortages,for example,academic influence is not strong.It is necessary to continue exploring and verifying key issues such as the causality and mechanisms underlying connections between hypertension and the gut microbiota.Research scope and quality must also expand and improve.
