RESUMEN

Background and Aim: Xuefu Zhuyu decoction (XZD), a traditional Chinese medicinal formula, was firstly recorded in the Qing dynasty of ancient China and previously demonstrated to ameliorate hepatic steatosis. In the present study, the effects of XZD on non-alcoholic fatty liver disease (NAFLD) induced by high-fat diet (HFD) were evaluated in mice and the hepatic transcriptome was detected to disclose the potential mechanisms of XZD. Experimental procedure: The effects of XZD (low- and high-dosage) on NAFLD induced by HFD for 16 weeks were evaluated. Obeticholic acid was used as control drug. Body weight, food intake and index of homeostatic model assessment for insulin resistance (HOMA-IR) were analyzed. Hepatic histology were observed in haematoxylin and eosin stained sections and quantified with NAFLD activity score (NAS). Lipid in hepatocytes was visualized by Oil red staining. Alanine aminotransferase (ALT) and hepatic triglyceride (TG) was measured. The hepatic transcriptom was detected with RNA-sequencing and validated with real-time polymerase chain reaction, western-blotting and hepatic quantitative metabolomics. Results: XZD ameliorated hepatic histology of NAFLD mice, accompanied with decreasing fasting insulin, HOMA-IR, NAS, ALT and hepatic TG. The hepatic transcriptom of NAFLD was significantly reversed by XZD treatment, especially the genes enriched in the pathways of arachidonic acid metabolism, fatty acid degradation, cytokine-cytokine receptor interaction and extracellular matrix (ECM) -receptor interaction. The hepatic quantitative metabolomics analysis confirmed fatty acid degradation as the key targeting pathway of XZD. Conclusions: XZD ameliorated NAFLD induced by HFD, which probably correlated closely to the pathways of fatty acid degradation.

RESUMEN

Theaflavins are the characteristic polyphenols in black tea which can be enzymatically synthesized. In this review, the effects and molecular mechanisms of theaflavins on obesity and its comorbidities, including dyslipidemia, insulin resistance, hepatic steatosis, and atherosclerosis, were summarized. Theaflavins ameliorate obesity potentially via reducing food intake, inhibiting pancreatic lipase to reduce lipid absorption, activating the adenosine monophosphate-activated protein kinase (AMPK), and regulating the gut microbiota. As to the comorbidities, theaflavins ameliorate hypercholesterolemia by inhibiting micelle formation to reduce cholesterol absorption. Theaflavins improve insulin sensitivity by increasing the signaling of protein kinase B, eliminating glucose toxicity, and inhibiting inflammation. Theaflavins ameliorate hepatic steatosis via activating AMPK. Theaflavins reduce atherosclerosis by upregulating nuclear factor erythropoietin-2-related factor 2 signaling and inhibiting plasminogen activator inhibitor 1. In randomized controlled trails, black tea extracts containing theaflavins reduced body weight in overweight people and improved glucose tolerance in healthy adults. The amelioration on the hyperlipidemia and the prevention of coronary artery disease by black tea extracts were supported by meta-analysis.

RESUMEN

Importance: Ginkgo diterpene lactone meglumine (GDLM) has attracted much attention because of its potential neuroprotective properties in ischemic stroke. The efficacy of GDLM in patients with acute ischemic stroke (AIS) needs to be verified by well-designed randomized clinical trials. Objective: To assess the efficacy and safety of GDLM in patients with AIS. Design, Setting, and Participants: This multicenter, randomized, double-blind, placebo-controlled, parallel-group trial involved 3448 patients who had AIS, were aged 18 to 80 years, had a clinically diagnosed AIS symptom within 48 hours of onset, had a modified Rankin Scale (mRS) score of 0 or 1 prior to onset, and had a National Institutes of Health Stroke Scale score ranging from 4 to 24. The trial took place at 100 centers in China from February 1, 2016, to May 1, 2018. The mRS is a global stroke disability scale with scores ranging from 0 (no symptoms or completely recovered) to 6 (death). The National Institutes of Health Stroke Scale is a tool used by clinicians to quantify impairment caused by stroke (range, 0-42, with higher scores indicating greater severity). Data were analyzed from January 2019 to December 2022. Interventions: Patients were randomized to receive GDLM or placebo once daily via intravenous infusion in a 1:1 ratio. The treatment was dispensed within 48 hours after symptoms and continued for 14 days. Interventions of thrombolysis and thrombectomy were not permitted during the treatment. Main Outcomes and Measures: The primary outcome was the proportion of patients with an mRS of 0 or 1 on day 90 after randomization. Safety outcomes included adverse events and serious adverse events. Results: A total of 3448 patients were randomized, with 1725 patients assigned to the GDLM group and 1723 patients assigned to the placebo group. The median (IQR) age of the patients was 63 (55-71) years, and 1232 (35.7%) were women. The primary outcome on day 90 occurred in 877 patients (50.8%) in the GDLM group, and 759 patients (44.1%) in the placebo group (risk difference, 6.79%; 95% CI, 3.46%-10.10%; odds ratio, 1.31; 95% CI, 1.15-1.50; relative risk, 1.15; 95% CI, 1.08-1.24; P < .001). Adverse events occurred relatively equally between the 2 groups (303 [17.6%] vs 298 [17.3%]; risk difference, 0.27%; 95% CI, -2.26% to 2.80%; odds ratio, 1.02; 95% CI, 0.85-1.21; relative risk, 1.02; 95% CI, 0.88-1.17; P = .83). Conclusions and Relevance: Among patients with AIS in this randomized clinical trial, GDLM improved the proportion of patients achieving favorable clinical outcomes at 90 days compared with placebo. Trial Registration: ClinicalTrials.gov Identifier: NCT02526225.

RESUMEN

Far-western blotting, derived from the western blot, has been used to detect interactions between proteins in vitro, such as receptor-ligand interactions. The insulin signaling pathway plays a critical role in the regulation of both metabolism and cell growth. The binding of the insulin receptor substrate (IRS) to the insulin receptor is essential for the propagation of downstream signaling after the activation of the insulin receptor by insulin. Here, we describe a step-by-step far-western blotting protocol for determining the binding of IRS to the insulin receptor.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Qushi Huayu Decoction (QHD) is a traditional Chinese medicine formula consisting of five herbs, which has been used for non-alcoholic fatty liver disease (NAFLD) treatment in clinic for decades in China and validated in several NAFLD animal models. The hepatic de novo lipogenesis (DNL) is enhanced greatly to contribute to steatosis in NAFLD. The spliced form of X-box binding protein 1 (XBP1s) initiates DNL independently of sterol regulatory element-binding protein (SREBP) and carbohydrate-responsive element-binding protein (ChREBP). AIM OF THE STUDY: To disclose the mechanism of inhibition on hepatic DNL by QHD and the responsible compounds. METHODS: The effects of QHD on hepatic DNL were evaluated in mice induced by high-fructose diet (HFru). The effects of the serum-absorbed compounds of QHD on XBP1s were evaluated in HepG2 cells induced by tunicamycin. Hepatic histology, triglyceride (TG) and nonesterified fatty acids were observed. Hepatic apolipoprotein B100 and very low-density lipoprotein were measured to reflect lipid out-transport. The mRNA expression of XBP1s and its target genes were detected by real-time polymerase chain reaction. The protein expression of TG synthetases and DNL enzymes, and inositol requirement enzyme 1 alpha (IRE1α), phosphorylated IRE1α and XBP1s were detected in liver tissue and HepG2 cells by western-blot. The binding activity of SREBP1, protein expression of ChREBP and XBP1s were detected in the nuclear extracts of liver tissue. RESULTS: Dynamical observing suggested feeding with HFru for 2 weeks was sufficient to induce hepatic lipogenesis and XBP1s. QHD ameliorated liver steatosis without enhancing out-transport of lipids, accompanied with more inhibitory effects on DNL enzymes than TG synthetases. QHD inhibits the nuclear XBP1s without affecting ChREBP and SREBP1. In QHD, chlorogenic acid, geniposide and polydatin inhibit lipogenesis initiated by XPB1s. CONCLUSION: QHD probably decreases hepatic DNL by inhibiting XBP1s independent of SREBP1 and ChREBP. Chlorogenic acid, geniposide and polydatin are the potential responsible compounds.

RESUMEN

Gut-derived lipopolysaccharide (LPS) leaking through the dysfunctional intestinal barrier contributes to the onset of non-alcoholic steatohepatitis (NASH) by triggering inflammation in the liver. In the present study, a combination consisting of Atractylodes macrocephala polysaccharide (A), chlorogenic acid (C), and geniposide (G) (together, ACG), was shown to ameliorate NASH in mice and reduce hepatic LPS signaling and endotoxemia without decreasing the abundance of identified Gram-negative bacteria through restoring the intestinal tight junctions. Our data indicated that inhibition of LPS gut leakage by the ACG combination contributed to its amelioration of NASH.

RESUMEN

Knockout of the transcription factor X-box binding protein (XBP1) is known to decrease liver glucose production and lipogenesis. However, whether insulin can regulate gluconeogenesis and lipogenesis through XBP1 and how insulin activates the inositol-requiring enzyme-XBP1 ER stress pathway remains unexplored. Here, we report that in the fed state, insulin-activated kinase AKT directly phosphorylates inositol-requiring enzyme 1 at S724, which in turn mediates the splicing of XBP1u mRNA, thus favoring the generation of the spliced form, XBP1s, in the liver of mice. Subsequently, XBP1s stimulate the expression of lipogenic genes and upregulates liver lipogenesis as previously reported. Intriguingly, we find that fasting leads to an increase in XBP1u along with a drastic decrease in XBP1s in the liver of mice, and XBP1u, not XBP1s, significantly increases PKA-stimulated CRE reporter activity in cultured hepatocytes. Furthermore, we demonstrate that overexpression of XBP1u significantly increases cAMP-stimulated expression of rate-limiting gluconeogenic genes, G6pc and Pck1, and glucose production in primary hepatocytes. Reexpression of XBP1u in the liver of mice with XBP1 depletion significantly increases fasting blood glucose levels and gluconeogenic gene expression. These data support an important role of XBP1u in upregulating gluconeogenesis in the fasted state. Taken together, we reveal that insulin signaling via AKT controls the expression of XBP1 isoforms and that XBP1u and XBP1s function in different nutritional states to regulate liver gluconeogenesis and lipogenesis, respectively.

RESUMEN

Inhibition of P300 acetyltransferase activity by specific inhibitor C646 has been shown to improve insulin signaling. However, the underlying molecular mechanism of this improvement remains unclear. In this study, we analyzed P300 levels of obese patients and found that they were significantly increased in liver hepatocytes. In addition, large amounts of P300 appeared in the cytoplasm. Inhibition of P300 acetyltransferase activity by C646 drastically increased tyrosine phosphorylation of the insulin receptor protein substrates (IRS1/2) without affecting the tyrosine phosphorylation of the beta subunit of the insulin receptor (IRß) in hepatocytes in the absence of insulin. Since IRS1/2 requires membrane translocation and binding to inositol compounds for normal functions, we also examined the role of acetylation on binding to phosphatidylinositol(4,5)P2 and found that IRS1/2 acetylation by P300 reduced this binding. In contrast, we show that inhibition of IRS1/2 acetylation by C646 facilitates IRS1/2 membrane translocation. Intriguingly, we demonstrate that C646 activates IRß's tyrosine kinase activity and directly promotes IRß interaction with IRS1/2, leading to the tyrosine phosphorylation of IRS1/2 and subsequent activation of insulin signaling even in the absence of insulin. In conclusion, these data reveal the unique effects of C646 in activating insulin signaling in patients with obesity and diabetes.

RESUMEN

Mitochondria are highly dynamic organelles of bacterial origin in eukaryotic cells. These play a central role in metabolism and adenosine triphosphate (ATP) synthesis and in the production and regulation of reactive oxygen species (ROS). In addition to the generation of energy, mitochondria perform numerous other functions to support key developmental events such as fertilization during reproduction, oocyte maturation, and the development of the embryo. During embryonic and neonatal development, mitochondria may have important effects on metabolic, energetic, and epigenetic regulation, which may have significant short- and long-term effects on embryonic and offspring health. Hence, the environment, epigenome, and early-life regulation are all linked by mitochondrial integrity, communication, and metabolism.

RESUMEN

In the past decade, G protein-coupled receptors have emerged as drug targets, and their physiological and pathological effects have been extensively studied. Among these receptors, GPR119 is expressed in multiple organs, including the liver. It can be activated by a variety of endogenous and exogenous ligands. After GPR119 is activated, the cell secretes a variety of incretins, including glucagon-like peptide-1 and glucagon-like peptide-2, which may attenuate the metabolic dysfunction associated with fatty liver disease, including improving glucose and lipid metabolism, inhibiting inflammation, reducing appetite, and regulating the intestinal microbial system. GPR119 has been a potential therapeutic target for diabetes mellitus type 2 for many years, but its role in metabolic dysfunction associated fatty liver disease deserves further attention. In this review, we discuss relevant research and current progress in the physiology and pharmacology of the GPR119/incretin axis and speculate on the potential therapeutic role of this axis in metabolic dysfunction associated with fatty liver disease, which provides guidance for transforming experimental research into clinical applications.

RESUMEN

Most currently recommended therapies for metabolic dysfunction-associated fatty liver disease (MAFLD) involve diet control and exercise therapy. We searched PubMed and compiled the most recent research into possible forms of programmed cell death in MAFLD, including apoptosis, necroptosis, autophagy, pyroptosis and ferroptosis. Here, we summarize the state of knowledge on the signaling mechanisms for each type and, based on their characteristics, discuss how they might be relevant in MAFLD-related pathological mechanisms. Although significant challenges exist in the translation of fundamental science into clinical therapy, this review should provide a theoretical basis for innovative MAFLD clinical treatment plans that target programmed cell death.

RESUMEN

Background: Non-alcoholic fatty liver disease (NAFLD), characterized by the excessive accumulation of hepatic triglycerides (TGs), has become a worldwide chronic liver disease. But efficient therapy keeps unsettled. Our previous works show that geniposide and chlorogenic acid combination (namely the GC combination), two active chemical components combined with a unique ratio (67.16:1), presents beneficial effects on high-fat diet-induced NAFLD rodent models. Notably, microarray highlighted the more than 5-fold down-regulated SCD-1 gene in the GC combination group. SCD-1 is an essential lipogenic protein for monounsaturated fatty acids' biosynthesis and serves as a key regulatory enzyme in the last stage of hepatic de novo lipogenesis (DNL). Methods: NAFLD mice model was fed with 16 weeks high-fat diet (HFD). The pharmacological effects, primarily on hepatic TG, TC, FFA, and liver enzymes, et al. of the GC combination and two individual components were evaluated. Furthermore, hepatic SCD-1 expression was quantified with qRT-PCR, immunoblotting, and immunohistochemistry. Finally, the lentivirus-mediated over-expressed cell was carried out to confirm the GC combination's influence on SCD-1. Results: The GC combination could significantly reduce hepatic TG, TC, and FFA in NAFLD rodents. Notably, the GC combination presented synergetic therapeutic effects, compared with two components, on normalizing murine hepatic lipid deposition and disordered liver enzymes (ALT and AST). Meanwhile, the robust SCD-1 induction induced by HFD and FFA in rodents and ALM-12 cells was profoundly blunted, and this potent suppression was recapitulated in lentivirus-mediated SCD-1 over-expressed cells. Conclusion: Taken together, our data prove that the GC combination shows a substantial and synergetic anti-lipogenesis effect in treating NAFLD, and these amelioration effects are highly associated with the potent suppressed hepatic SCD-1 and a blunted DNL process.

RESUMEN

BACKGROUND: Gut microbiota is increasingly recognized as the key participant in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) by translocation of its products, such as lipopolysaccharide (LPS), via the dysfunctional intestinal barrier. Qushi Huayu decoction (QHD), a traditional Chinese medicine, is developed specially for NAFLD and used in clinic in China for more than a decade and previously found to ameliorate non-alcoholic steatohepatitis (NASH) induced by high-fat diet (HFD) in mice accompanied with inhibited metabolic endotoxemia and hepatic LPS signalling. PURPOSE: To investigate the mechanism of LPS gut-leakage inhibition by QHD in NASH. METHODS: Effects of QHD on gut microbioa and intestinal barrier were evaluated in NASH induced by HFD in mice. 16S rRNA sequencing is employed to analyse the gut microbiota composition. To identify the potential signalling pathway responsible for tight junction regulation, the colonic phosphoprotein profile is screened via the Phospho Explorer Antibody Array and verified in NASH, intestinal barrier dysfunctional mouse and Caco-2 cells. RESULTS: QHD ameliorates NASH accompanied with regulating the gut microbiota composition, protecting intestinal tight junctions and inhibiting LPS gut-leakage without decreasing the abundance of identified Gram-negative bacteria. The validated data of phosphorylated proteins suggested that mitogen-activated protein kinase (MAPK) pathway is predominantly responsible for the colonic tight junction regulation by QHD. CONCLUSION: QHD inhibits LPS gut-leakage in NASH, which is associated with downregulation of intestinal MAPK pathway.

RESUMEN

Fuzheng Huayu (FZHY) capsule is a traditional Chinese medicine composed of six Chinese medicinal herbs Tian et al. [1] and approved by China food and drug administration for liver fibrosis treatment [2], [3] Liu et al., 2009 and Liu et al., 2005. CGA formula consisting of Cordyeps sinensis polysaccharide (CS-PS), gypenosides (G), and amygdalin (A), are derived from FZHY formula. It is necessary to identify the chemical profile of FZHY and CGA formula to describe the mechanisms and the corresponding components of anti-fibrosis. It is showed that FZHY contains adenosine (5.21 mg/g), amygdalin (5.31 mg/g), salvianolic acid b (18.22 mg/g) and deoxyschizandrin (2.62 mg/g), respectively. CS-PS contained 60.5 ± 2.2% total carbohydrate, including 14.17% arabinose, 25.35% glucose and 60.48% galactose. Gypenosides contain 10.34% gypenosides XLIX and 16.58% gypenosides A. These data provide the primary chemical profile of FZHY and CGA formula and an example for components analysis of traditional Chinese medicine.

RESUMEN

The ventriculoperitoneal (VP) shunt is a gold standard procedure to treat hydrocephalus. However, shunt malfunction is the common complications after surgery. In this study, we utilize phase-contrast cine magnetic resonance imaging (PC cine MRI) to improve the diagnosis of VP shunt malfunction. In in vitro and in vivo experiment results demonstrate the cerebrospinal fluid (CSF) flow velocities in the shunt tube are significantly decreased in the shunt malfunction group, which indicated PC cine MRI could evaluate the CSF flow dynamics of VP shunt effectively. This method is noninvasive and simple, also can improve the diagnosis of shunt malfunction.

RESUMEN

ETHNOPHARMACOLOGICAL RELEVANCE: Fuzheng-Huayu formula (FZHY) is traditionally used to treat liver fibrosis in clinic. The study was conducted to investigate the metabolic mechanisms of FZHY against liver fibrosis in rats. MATERIALS AND METHODS: Rats with CCl4 -induced liver fibrosis were treated with FZHY and its components, including amygdalin, cordyceps polysaccharide and gypenoside, respecitively. Liver fibrosis and function were assesed by histopathological examination, Western blot and serum biochemical detection. Metabolic profiling of liver tissue, serum and urine in each group were detected by gas chromatography-mass spectrometry (GC-MS) and transcriptomic changes were tested by gene chip. RT-qPCR was used to validate levels of different expressed genes (DEGs) with statistical significance. Metabolic network together with DEGs was constructed based on KEGG database. RESULTS: FZHY effectively improved liver fibrosis better than the mixture or single use of gypenoside, cordyceps sinensis mycelia and amygdalin. FZHY treatment widely modulated the metabolic profiles perturbed by liver fibrosis, involving several important metabolic pathways, including glycolysis/gluconeogenesis, glucose-alanine cycle, citrate cycle, galactose metabolism, tryptophan metabolism, urea cycle, etc. It also increased alanine and decreased glucose levels in liver tissue and decreased both of them in serum and urine, which were dysregulated by CCl4 treatment. Additionally, FZHY also upregulated expression of metabolic enzymes including Hk2, Adh1 and Gpt increased, and downregulated Gs and Acss2. CONCLUSION: FZHY improved liver fibrosis in rats via altering the metabolic pathways and regulating gene expression of involved metabolic enzymes.

RESUMEN

Nonalcoholic fatty liver disease (NAFLD) is becoming a worldwide health problem, but no approved medical treatment exists so far. Nuclear receptors are one of the drug targets for nonalcoholic steatohepatitis (NASH). Among them, liver X receptor (LXR) has been studied in recent years in tumors, metabolic diseases and inflammatory diseases, but its physiological and pharmacological effects in the treatment of NASH are controversial. Activation of LXR has the potential to modulate cholesterol homeostasis, induce anti-inflammatory effects and increase insulin sensitivity, but liver lipid deposition and hypertriglyceridemia are also increased. Inhibition of liver LXR transcriptional activity in the context of NAFLD can effectively alleviate hepatic steatosis, inflammation, and fibrosis but elevates the risk of potential cardiovascular disease. The contradictory pharmacodynamic effects of LXR in the treatment of NASH increase the difficulty of developing targeted drugs. Moreover, natural compounds play an important part in drug development, and in recent years, some natural compounds have been reported to treat NAFLD by acting on LXR or LXR pathways with fewer adverse reactions, presenting a promising therapeutic prospect. In this review, we discuss the mechanisms of LXR in NASH and summarize the natural products reported to modulate NAFLD via LXR or the LXR pathway, offering an alternative approach for LXR-related drug development in NAFLD.

RESUMEN

ETHNOPHARMACOLOGICAL REVELVANCE: CGA consisting of Cordyceps sinensis mycelia polysaccharide, gypenosides and amygdalin, was demonstrated to be the effective components formula in Fuzheng Huayu (FZHY) capsule, a traditional Chinese medicine approved by China food and drug administration for treatment of liver fibrosis and to inhibit transforming growth factor-ß1 (TGF-ß1) signaling, previously. AIM OF THE STUDY: To evaluate the effects of CGA on hepatic apoptosis in liver fibrosis induced by carbon tetrachloride (CCl4). MATERIALS AND METHODS: The hepatic injury and histology was detected by serum biomarker assay and hematoxylin-eosin staining. The hepatic collagen was illustrated by Sirius red staining and hydroxyproline (Hyp) concentration. The hepatic stellate cells (HSCs) activation and hepatic apoptosis was visualized by immunohistochemical analysis of α-smooth muscle actin (α-SMA) and terminal deoxynucleotidyl transferase-mediated dUPT nick-end labeling (TUNEL) assay respectively. The protein expression of collagen type I (Col-I), α-SMA, TGF-ß1, Fas, tumor necrosis factor receptor 1 (TNF-R1), cleaved-caspase-8, cleaved-caspase-10, cleaved-caspase-9, cleaved-caspase-3, mitochondrial Bcl-2, Bcl-2 associated X protein (Bax), Bcl-2 homologous antagonist/killer (Bak), cytochrome C and cytoplasmic cytochrome C was detected by western-blot. RESULTS: CGA or FZHY ameliorated liver histological changes, decreasing serum alanine aminotransferase, aspartate aminotransferase, hepatic Hyp, TUNEL positive-stained area, and down-regulated the protein expression of α-SMA, TGF-ß1, Col-I, Fas, TNF-R1, cleaved-caspase-8, cleaved-caspase-10, cleaved-caspase-9, and cleaved-caspase-3, mitochondrial Bax, Bak, and cytoplasmic cytochrome C, while restored the expression of mitochondrial Bcl-2 and cytochrome C. CONCLUSION: CGA formula ameliorates liver fibrosis induced by CCl4, which is correlated to its inhibition on hepatic apoptosis.

RESUMEN

AIM: To elucidate tongue coating microbiota and metabolic differences in chronic hepatitis B (CHB) patients with yellow or white tongue coatings. METHODS: Tongue coating samples were collected from 53 CHB patients (28 CHB yellow tongue coating patients and 25 CHB white tongue coating patients) and 22 healthy controls. Microbial DNA was extracted from the tongue samples, and the bacterial 16S ribosomal RNA gene V3 region was amplified from all samples and sequenced with the Ion Torrent PGM™ sequencing platform according to the standard protocols. The metabolites in the tongue coatings were evaluated using a liquid chromatography-mass spectrometry (LC-MS) platform. Statistical analyses were then performed. RESULTS: The relative compositions of the tongue coating microbiotas and metabolites in the CHB patients were significantly different from those of the healthy controls, but the tongue coating microbiota abundances and diversity levels were not significantly different. Compared with the CHB white tongue coating patients, the CHB yellow tongue coating patients had higher hepatitis B viral DNA (HBV-DNA) titers (median 21210 vs 500, respectively, P = 0.03) and a significantly lower level of Bacteroidetes (20.14% vs 27.93%, respectively, P = 0.013) and higher level of Proteobacteria (25.99% vs 18.17%, respectively, P = 0.045) in the microbial compositions at the phylum level. The inferred metagenomic pathways enriched in the CHB yellow tongue coating patients were mainly those involved in amino acid metabolism, which was consistent with the metabolic disorder. The abundances of bacteria from Bacteroidales at the order level were higher in the CHB white tongue coating patients (19.2% vs 27.22%, respectively, P = 0.011), whereas Neisseriales were enriched in the yellow tongue coating patients (21.85% vs 13.83%, respectively, P = 0.029). At the family level, the abundance of Neisseriaceae in the yellow tongue patients was positively correlated with the HBV-DNA level but negatively correlated with the S-adenosyl-L-methionine level. CONCLUSION: This research illustrates specific clinical features and bacterial structures in CHB patients with different tongue coatings, which facilitates understanding of the traditional tongue diagnosis.

RESUMEN

Inflammation contributes heavily to the pathogenesis of liver fibrosis, cirrhosis, and even hepatocellular carcinoma. Inflammation is probably a promising target for treatment of liver diseases. The natural products are considered as the potential source of new drug discovery and their pharmacological effects on hepatic inflammation have been widely reported. In this review, the natural products with anti-hepatic inflammatory properties are summarized based on their pharmacological effects and mechanisms, which are related to the suppression on the inflammation mediators including cytokines and chemokines, pattern recognition receptors, the activated transcriptional factors, and the potential regulatory factors. The clinical evidence is also summarized.
