    Abstract
  •   Objective  To investigate the protective effect of fecal microbiota transplantation (FMT) on mice with acute-on-chronic liver failure (ACLF) and its effect on intestinal flora.  Methods  A total of 40 mice were randomly divided into control group (CON group), model group (MOD group), FMT group (feces of the mice in the CON group were used as fecal microbiota donor), and FMT model group (ANFMT group, with feces of the mice in the MOD group as fecal microbiota donor), with 10 mice in each group. All mice were observed in terms of body weight, death, liver histopathology, and changes in aspartate aminotransferase (AST), alanine aminotransferase (ALT), and intestinal flora. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the SNK-q test was used for further comparison between two groups.  Results  Compared with the CON group, the MOD group had a significant reduction in body weight and significant increases in AST and ALT (all P < 0.05), as well as large patchy necrosis of hepatocytes, significant increases in Verrucomicrobia, Akkermansia, and Erysipelatoclostridium, and significant reductions in Dubosiella and Duncaniella (all P < 0.05). Compared with the CON group, the ANFMT group had a significant increase in AST (P < 0.05), hepatocyte swelling and mild ballooning degeneration, significant increases in Unclassified and Faecalibaculum, and significant reductions in Patescibacteria, Deferribacteres, Muribaculum, Candidatus_Saccharimonas, Rikenella, Odoribacter, Mucispirillum, and Lachnospiraceae_unclassified (all P < 0.05). Compared with the MOD group, the FMT group had significant reductions in AST and ALT (both P < 0.05), mild hepatocellular necrosis and marked ballooning degeneration, significant increases in Paramuribaculum and Bilophila, and significant reductions in Firmicutes, Rikenella, and Absiella (all P < 0.05).  Conclusion  Intestinal flora disturbance is observed in ACLF mice, and dysbacteriosis may lead to liver injury. FMT can alleviate liver inflammation in ACLF mice and thus exert a protective effect.
