Abstract: 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.
