BACKGROUND:Dysregulated microbiota is a hallmark of end-stage liver disease (ESLD). This study aimed to elucidate the intrahepatic microbiome in hepatitis B virus (HBV)-related ESLD. METHODS:We collected liver tissue samples from patients undergoing liver transplantation due to decompensated cirrhosis (DC) (n = 20) or acute-on-chronic liver failure (ACLF) (n = 24), as well as 18 samples from donors. Metatranscriptomic sequencing was performed to profile liver microbiome and transcriptome. RESULTS:2208 bacterial species were detected across 13 phyla and 165 genera. Metatranscriptomic profiling revealed that Proteobacteria and Actinobacteria dominated the intrahepatic microbiome, with Escherichia coli and Pseudomonas most prevalent across groups. Principal coordinate analysis showed distinct microbial community structures among donors, DC, and ACLF patients. Compared with donors, both groups exhibited increased abundance of Bacteroides heparinolyticus, Moraxella osloensis, and Gardnerella vaginalis, while ACLF patients were further enriched with Alcaligenes faecalis and Burkholderia insecticola, and DC patients had higher B. heparinolyticus. Most taxa originated from the gut, with additional oral- and respiratory-derived species. Despite similar abundance between groups, E. coli in ESLD displayed marked functional activation, including nutrient acquisition systems and virulence factors linked to adhesion, invasion, and toxin production. Integrated host - microbiome analysis revealed taxa-specific associations with impaired hepatic metabolic, immune, and structural integrity. CONCLUSION:This study delineates the compositional and functional reprogramming of the intrahepatic microbiome in patients with ESLD and its coupling with liver metabolic, immune, and structural pathways. These findings suggest the intrahepatic microbiome as a promising therapeutic target for ESLD.
BACKGROUND:Metabolic-associated fatty liver disease (MAFLD) is a prevalent chronic liver condition globally, characterized by suboptimal treatment outcomes. Traditional therapies often fail to address the multifaceted pathogenesis of MAFLD, which involves lipid metabolism, inflammation, and gut-liver axis dysregulation. JiGuCao Capsule formula (JCF), a patented Chinese medicine, has demonstrated clinical efficacy in liver disease treatment, indicating its potential as a new therapeutic option for MAFLD. PURPOSE:This study aimed to investigate the therapeutic effects and underlying mechanisms of JCF in treating MAFLD, particularly focusing on its impact on liver pathology, intestinal health, and gut microbiota composition. METHODS:A MAFLD mouse model was developed by administering a high-fat diet and 5% fructose water for 16 weeks. At week 8, mice exhibited significant steatosis, inflammation, and insulin resistance. Fifty mice were allocated into two groups: the normal diet (ND) group with 19 mice and the high-fat feed diet (HFD) group with 31 mice. Seven mice from each group were sacrificed at week 8 for serological and histopathological assessments. The remaining mice were allocated into ND (n = 6), HFD (n = 6), HFD + JCFL (human equivalent dose,780 mg/kg, n = 6), HFD + JCFH (threefold the human equivalent dose, 2340 mg/kg, n = 6), HFD + Polyene Phosphatidylcholine (PPC) (human equivalent dose,177.84 mg/kg, n = 6) and ND+ JCF (human equivalent dose,780 mg/kg, n = 6) groups. Daily gavage started at week 9. At week 16, after fasting, body weight and liver condition were recorded, and mice were euthanized with pentobarbital sodium. Mouse tissues and feces were collected for histopathological, molecular biological, and multi-omics analyses. RESULTS:JCF effectively slowed MAFLD progression in mice by decreasing hepatic lipid accumulation and inflammation. Treatment with JCF significantly reduced hepatic triglycerides and inflammatory markers, including TNF-α and IL-6. JCF enhanced lipid metabolism, repaired the intestinal barrier, and lowered inflammatory cytokines in the intestines, as indicated by reduced serum LPS and restored tight junction proteins expression, such as claudin-1 and occludin. Fecal microbiota analysis indicated that JCF treatment elevated Lactobacillus levels and reduced Colidextribacter levels, correlating with enhanced metabolic profiles. The primary bioactive compounds identified in JCF responsible for these therapeutic effects were betulinic acid, cholic acid, deoxycholic acid, oleanolic acid, and pectolinarigenin. Transcriptomic analysis showed that JCF regulated key pathways involved in lipid metabolism, including the pparγ-cd36 axis and modulation of ox-LDL levels. The results indicate that JCF effectively mitigates MAFLD by influencing the gut-liver axis and lipid metabolism. CONCLUSION:JCF alleviates MAFLD by modulating the gut-liver axis and lipid metabolism. Its effects involve improving gut barrier function, regulating microbiota, and targeting the pparγ-cd36 axis. Active compounds like betulinic acid support its therapeutic potential. JCF shows promise as a novel treatment for MAFLD, with further clinical studies needed.
ABSTRACT Aims The TiaoGanXiaoZhi formula (TGXZ), a traditional Chinese medicine, has been shown to alleviate the progression of metabolic‐associated fatty liver disease (MAFLD) clinically. However, its underlying mechanism remains unclear. This study aimed to investigate the effects and mechanisms of TGXZ in treating MAFLD in mouse models. Methods The MAFLD mouse model was established using a high‐fat diet and 5% fructose water over 16 weeks. At Week 8, mice exhibited significant steatosis, inflammation, and insulin resistance. A total of 42 mice were divided into the normal feed diet (NFD) group (n = 18) and the high‐fat feed diet (HFD) group (n = 24). Six mice from each group were killed at Week 8 for serological and histopathological assessments. The remaining mice were allocated into NFD (n = 6), HFD (n = 6), HFD + TGXZ (n = 6), NFD + TGXZ (n = 6), and HFD + Placebo (n = 6) groups. TGXZ (or placebo) was administered at a clinical equivalent dose of 7.699 g/(kg·d) to the respective groups, while NFD and HFD groups received distilled water. Daily gavage started in Week 9. At Week 16, after fasting, body weight and liver condition were recorded, and mice were euthanized with pentobarbital sodium. Liver tissue was collected for further analysis, and the remaining tissue and feces were stored at −80°C. Data were graphed using GraphPad Prism 8.0.0 and analyzed with SPSS Statistics 25.0. Results are expressed as mean ± standard deviation. Statistical comparisons were made using Student's t‐test for two groups and one‐way ANOVA for more than two groups, with significance set at p < 0.05. Results Compared to the MAFLD mouse model group, TGXZ treatment significantly downregulated the weight of white adipose tissue (1.61 ± 0.66 vs. 3.06 ± 0.34 g, p < 0.0010), liver weight (1.22 ± 0.16 vs. 1.98 ± 0.39 g, p = 0.0031), and the levels of alanine aminotransferase (20.6 ± 3.4 vs. 46.1 ± 12.3 U/L, p < 0.0010), aspartate aminotransferase (99.9 ± 19.1 vs. 168.4 ± 34.3 U/L, p = 0.0014), cholesterol (2.95 ± 0.56 vs. 4.38 ± 0.34 mmol/L, p = 0.0053), triglycerides (2.25 ± 0.41 vs. 4.18 ± 0.67 mmol/L, p < 0.0010), low‐density lipoprotein (0.66 ± 0.11 vs. 1.41 ± 0.52 mmol/L, p = 0.0073), and total bile acid (0.71 ± 0.41 vs. 2.18 ± 0.61 mmol/L, p = 0.0017), except for high‐density lipoprotein (2.41 ± 0.81 vs. 2.55 ± 0.31 mmol/L, p = 0.5655). The liver transcriptome, fecal microbiota sequencing, and fecal lipidomics analysis demonstrated that TGXZ treatment improved the expression of genes related to lipid metabolism, alleviated intestinal microbiota disorders, and mitigated lipid disturbances caused by MAFLD. Conclusions Our study demonstrated that TGXZ treatment effectively alleviated the progression of MAFLD. The inhibitory effects of TGXZ on MAFLD may be attributed to its regulation of gut microbiota, lipid metabolism, and hepatic inflammation.

The JiGuCao capsule formula (JCF) has demonstrated promising curative effects in treating chronic hepatitis B (CHB) in clinical trials. Here, we aimed to investigate JCF's function and mechanism in diseases related to the hepatitis B virus (HBV). We used mass spectrometry (MS) to identify the active metabolites of JCF and established the HBV replication mouse model by hydrodynamically injecting HBV replication plasmids into the mice's tail vein. Liposomes were used to transfect the plasmids into the cells. The CCK-8 kit identified cell viability. We detected the levels of HBV s antigen (HBsAg) and HBV e antigen (HBeAg) by the quantitative determination kits. qRT-PCR and Western blot were used to detect the genes' expression. The key pathways and key genes related to JCF on CHB treatment were obtained by network pharmacological analysis. Our results showed that JCF accelerated the elimination of HBsAg in mice. JCF and its medicated serum inhibited HBV replication and proliferation of HBV-replicating hepatoma cells in vitro. And the key targets of JCF in treating CHB were CASP3, CXCL8, EGFR, HSPA8, IL6, MDM2, MMP9, NR3C1, PTGS2, and VEGFA. Furthermore, these key targets were related to pathways in cancer, hepatitis B, microRNAs in cancer, PI3K-Akt signaling, and proteoglycans in cancer pathways. Finally, Cholic Acid, Deoxycholic Acid, and 3', 4', 7-Trihydroxyflavone were the main active metabolites of JCF that we obtained. JCF employed its active metabolites to perform an anti-HBV effect and prevent the development of HBV-related diseases.

The Chinese traditional medicine KangXianYiAi formula (KXYA) is used to treat hepatic disease in the clinic. Here we aim to confirm the therapeutic effects and explore the pharmacological mechanisms of KXYA on hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). We first collected and analyzed clinical data of 40 chronic hepatitis B (CHB) patients with precancerous liver lesions under KXYA treatment. Then, the cell viability, migration, cell cycle, and apoptosis of HepAD38 cells with KXYA treatment were examined. Next, we performed network pharmacological analysis based on database mining to obtain the key target pathways and genes of KXYA treatment on HBV-related HCC. We finally analyzed the expression of the key genes between normal and HBV-related HCC tissues in databases and measured the mRNA expression of the key genes in HepAD38 cells after KXYA treatment. The KXYA treatment could reduce the liver nodule size of CHB patients, suppress the proliferation and migration capabilities, and promote apoptosis of HepAD38 cells. The key pathways of KXYA on HBV-related HCC were Cancer, Hepatitis B, Viral carcinogenesis, Focal adhesion, and PI3K-Akt signaling, and KXYA treatment could regulate the expression of the key genes including HNF4A, MAPK8, NR3C1, PTEN, EGFR, and HDAC1. The KXYA exhibited a curative effect via inhibiting proliferation, migration, and promoting apoptosis of HBV-related HCC and the pharmacological mechanism was related to the regulation of the expression of HNF4A, MAPK8, NR3C1, PTEN, EGFR, and HDAC1.
Background: Xiaoxianxiong decoction is a classic formula in traditional Chinese medicine used to treat type 2 diabetes mellitus and proven to be effective. But the material basis and underlying mechanisms remain unclear. The aim of the present study was to elucidate the potential effective material basis of Xiaoxianxiong decoction and molecular mechanism treating type 2 diabetes mellitus. Methods: The absorbed bioactive components were identified based on serum pharmacochemistry. Network analysis were performed to obtain effect targets for docking verification with the absorbed prototypes to determine the potential effective material basis. On the above basis, network pharmacology was conducted to explore the molecular mechanism. Results: 76 compounds were identified of Xiaoxianxiong decoction and 61 absorbed bioactive compounds were investigated. Serine/threonine kinase 1 and ALB were key targets acquired by network analysis for molecular docking. Subsequently, 5 compounds were considered as the potential effective material basis, namely berberine, berberrubine, lariciresinol and gingerenone A, jatrorrhizine. Further, the mechanism mainly lies in the insulin signaling pathway, HIF-1 signaling pathway, PI3K-Akt signaling pathway, FoxO signaling pathway, AGE-RAGE signaling pathway in diabetic complications, phospholipase D signaling pathway to regulate blood glucose levels on target tissues as well as organs and exhibit anti-inflammatory, promote cell differentiation and cell growth, maintain oxygen homeostasis and affect the enzymes along with key metabolites. Conclusion:This integrated research strategy to investigate the treatment of Xiaoxianxiong decoction on type 2 diabetes mellitus provides valuable insights for further study and clinical practice of Xiaoxianxiong decoction.
Background and Aims: Chronic hepatitis B (CHB) patients with normal alanine aminotransferase (ALT) levels are at risk of disease progression. Currently, liver biopsy is suggested to identify this population. We aimed to establish a non-invasive diagnostic model to identify patients with significant liver inflammation. Method: A total of 504 CHB patients who had undergone liver biopsy with normal ALT levels were randomized into a training set ( n = 310) and a validation set ( n = 194). Independent variables were analyzed by stepwise logistic regression analysis. After the predictive model for diagnosing significant inflammation (Scheuer's system, G ≥ 2) was established, a nomogram was generated. Discrimination and calibration aspects of the model were measured using the area under the receiver operating characteristic curve (AUC) and assessment of a calibration curve. Clinical significance was evaluated by decision curve analysis (DCA). Result: The model was composed of 4 variables: aspartate aminotransferase (AST) levels, γ-glutamyl transpeptidase (GGT) levels, hepatitis B surface antigen (HBsAg) levels, and platelet (PLT) counts. Good discrimination and calibration of the model were observed in the training and validation sets (AUC = 0.87 and 0.86, respectively). The best cutoff point for the model was 0.12, where the specificity was 83.43%, the sensitivity was 77.42%, and the positive likelihood and negative likelihood ratios were 4.67 and 0.27, respectively. The model's predictive capability was superior to that of each single indicator. Conclusion: This study provides a non-invasive approach for predicting significant liver inflammation in CHB patients with normal ALT. Nomograms may help to identify target patients to allow timely initiation of antiviral treatment.
