Abstract:
Objective:To analyze the hotspots and trends of global researches in the field of hepatitis B from 2016 to 2021.Methods:Based on the Web of Science Core Collection Database, the indexed "article" and "review" related to hepatitis B from January 1, 2016 to November 22, 2021 were collected. Using InCites and VOSviewer 1.6.8 to cluster the published features, highly cited papers, key research directions and subject headings.And combined with the specific content of the literature, a summary of research hotspots was formed and analyzed.Results:As of November 22, 2021, a total of 12 299 articles were retrieved. From 2016 to 2021, the numbers of global hepatitis B-related research publications were 2 045, 1 996, 2 039, 2 118, 2 186 and 1 915, respectively. China′s mainland published the most papers (4 422 pieces, 35.95%), with the average citation frequency of only 7.46, and the United States ranked second in terms of the number of papers published (1 949 pieces, 15.85%), with the average citation frequency of 13.78. The hotspots obtained after the clustering of keyword topics were hepatitis B virus (HBV) infection, coinfections of HBV and hepatitis C virus/human immunodeficiency virus, primary hepatocellular carcinoma, antiviral therapy and hepatitis B cure, HBV virology, HBV and immunology, HBV reactivation, HBV vaccine, etc.Conclusions:In the past six years, global researches in the field of hepatitis B have focused on hepatitis B epidemiology and management, prediction and prevention of hepatitis B-related liver cancer, hepatitis B cure and treatment optimization, HBV virology and host immune mechanism in the development of hepatitis B, etc.The number of published papers in the field of hepatitis B keeps relatively stable. The number of researches in China′s mainland is at the international leading level, but the influence of researches needs to be further improved.
