The number of articles on the relationships between the intestinal microbiota and liver diseases has continued to increase. The aim of this study was to assess publications on this topic, identify research hotspots, and predict trends of future research. Articles on this topic published from 2001 to 2021 were obtained from the Web of Science Core Collection. Bibliometric analysis and visualization were performed to identify research hotspots and trends with the use of the online bibliometric analysis platform, VOSviewer, and CiteSpace. In total, 4415 articles were included for bibliometric analysis. The annual output of research on this topic gradually increased over the past 21 years. China contributed the most publications (1254), while the United States was the core (centrality = 0.35) of the country-cooperation network and Schnabl B published the most articles (n = 80). High-frequency keywords included "gut microbiota", "inflammation", "obesity", "insulin resistance", "disease", "fatty liver disease", "metabolism", and "probiotics". The keywords that have burst in recent years include "intestinal microbiota", "dysbiosis", and "gut-liver axis". The relationships between dysbiosis of the intestinal microbiota and liver diseases, such as nonalcoholic fatty liver disease (NAFLD), cirrhosis, and hepatocellular carcinoma (HCC), are current research hotspots. Treatment for NAFLD, nonalcoholic steatohepatitis, cirrhosis, and HCC via regulation of the intestinal microbiota is predicted as a research hotspot in the following years, especially immunotherapy for HCC. These findings should prove helpful to scholars to direct future research on the relationships between the intestinal microbiota and liver diseases.

Aim: We sought to investigate the impact of CpG oligodeoxynucleotides (CpG-ODN) administration on the lung and gut microbiota in asthmatic mice, specifically focusing on changes in composition, diversity, and abundance, and to elucidate the microbial mechanisms underlying the therapeutic effects of CpG-ODN and identify potential beneficial bacteria indicative of its efficacy.
Methods: HE staining were used to analyze inflammation in lung, colon and small intestine tissues. High-throughput sequencing technology targeting 16S rRNA was employed to analyze the composition, diversity, and correlation of microbiome in the lung, colon and small intestine of control, model and CpG-ODN administration groups.

Intestinal helminths have evolved an abundance of immunomodulatory mechanisms to ensure long-lived infections in mammalian hosts. To manipulate mammalian immune responses helminths can directly produce immunomodulatory molecules, but helminth infection can also elicit functional changes in the intestinal microbiome which can impact immune functioning. Here we examined how bile acids (BA)s, a group of host-produced, microbiota-modified immunomodulatory metabolites, were altered in abundance and composition during a murine small intestinal helminth infection.

Advancing microbiome-gut-brain axis science requires systematic, rational and translational approaches to bridge the critical knowledge gaps currently preventing full exploitation of the gut microbiome as a tractable therapeutic target for gastrointestinal, mental and brain health. Current research is still marked by many open questions that undermine widespread application to humans. For example, the lack of mechanistic understanding of probiotic effects means it remains unclear why even apparently closely related strains exhibit different effects in vivo.
