Current trends and research hotspots in the study of flavonoids for ulcerative colitis: A bibliometric study.

Abstract

Background and study aims: Flavonoids have been shown to exhibit significant potential in treating ulcerative colitis (UC), and their mechanism of action is receiving increasing attention. This study was devoted to the bibliometric analysis of articles and review articles in flavonoid therapy for UC research between 2011 and 2022 to show publication trends and research hotspots.

Material and methods: The literature search data for the bibliometric analysis were obtained from the Web of Science Core Collection by searching for the terms "Flavonoids" and "Ulcerative colitis or Idiopathic Proctocolitis or colitis gravis or Inflammatory Bowel Disease, Ulcerative Colitis Type." Three software programs, Bibliometrix, CiteSpace, and VOSviewer, were used to perform a bibliometric analysis of the retrieved literature data.

Results: There were 181 publications on flavonoids for UC during the 12 years, with an upward trend in annual publications and an annual growth rate of 27.11 %. China had the highest cumulative number of publications, and Kyung Hee University was the academic institution with the most publications in this research area. In recent years, intestinal flora, intestinal barrier, apoptosis, tight protein junctions, and TLR4/ NF-κB pathway have become hot spots for research on flavonoids for UC. Grape seed analogs have been extensively investigated for treating UC in the past three years.

Conclusion: The results of this bibliometric study demonstrate the current status and trends of research on flavonoids for the treatment of UC and provide relevant researchers with hot topics and the latest research directions.
