Abstract
Alcoholic liver disease (ALD) is a liver disease caused by heavy drinking. Porphyromonas gingivalis (P.g), a major cause of periodontitis, whose antibodies are elevated in severe ALD patients in the plasma. The purpose of this study is to further study the role and the molecular mechanism of P.g in the progress of ALD. In this study, saliva of patients with ALD was collected. Then, an animal model of ALD with oral P.g administration was established, pathology of liver and spleen, intestinal microorganisms and metabolites were analyzed. The molecular mechanism of P.g on ALD was analyzed in vitro. ALD and intestinal microflora and metabolite changes were observed more serious in the alcohol and P.g groups than the alcohol group. Moreover, ferroptosis was aggravated by P.g in the liver. Meanwhile, P.g promoted ferroptosis accomplication with alcohol in vitro, which can be reversed by ferroptosis inhibitors. In conclusion, P.g aggravates ALD through exacerbation gut microbial metabolic disorder in mice with alcohol, which maybe depend on ferroptosis activation in hepatocytes. The study provides a new strategy for prevention and treatment of ALD by improving the oral micro-environment.

Abstract
A low-carbohydrate high-fat (LCHF) dietary pattern has been reported to improve chronic metabolic diseases. However, whether and how the LCHF diet affects the pathological progression in patients with alcohol-related liver diseases (ALD) is largely unknown. This study was conducted to evaluate the effect of the LCHF diet on ALD and clarify its potential mechanism(s). The ALD model was established by feeding C57BL/6N mice with a Lieber-DeCarli liquid alcohol diet with a modified carbohydrate/fat ratio under an isoenergetic pattern. After an eight-week intervention, we observed that the LCHF diet significantly reduced alcohol-induced hepatic steatosis and liver injury, along with improved lipid metabolic-related gene disorders and redox imbalance. The alcohol-stimulated increase in pro-inflammatory cytokine cytokines expression, including TNF-α, IL-1β, and IL-6, was markedly reversed by the LCHF diet. Liver transcriptome sequencing and qPCR validation showed that twenty-four alcohol-disturbed genes were significantly reversed by LCHF-diet intervention. The top differentially expressed genes were selected for further investigation. Among them, 6-phosphogluconate dehydrogenase (6PGD) was significantly up-regulated by alcohol treatment in both the liver and cultured hepatocytes. Spearman correlation analysis revealed that 6PGD was positively associated with hepatic steatosis, liver injury, and oxidative stress indexes. In vitro, the 6PGD knockdown ameliorated alcohol-induced hepatotoxicity and intracellular lipid accumulation, as well as lipid metabolic-related gene disorders, implying the involvement of 6PGD in LCHF-protected ALD. In conclusion, LCHF diet intervention alleviated chronic alcohol consumption-induced liver dysfunction in mice. 6PGD is a potential novel target for ALD prevention that contributes to LCHF-improved ALD. A LCHF diet might be a promising choice for ALD management.

Abstract
Epimedium sagittatum (Sieb. et Zucc.) Maxim., a traditional medicinal plant in Asia, is widely used in clinical settings but its safety in vivo is unclear. This study investigated the sub-chronic toxicity of E. sagittatum aqueous extract to rats with a 13-week daily intragastric administration of 7.5, 15, or 30 g/kg. Nine constituents of the aqueous extract were identified by ultra-performance liquid chromatography (UPLC). Organ weights, organ coefficients, serum biochemistry parameters, histopathology, and metabolomic analysis were performed. In female rats, treatment increased the liver, thymus, and adrenal gland coefficients (p < 0.05). Liver, pancreas, and adrenal gland injury were observed. The levels of six metabolites were altered by the treatment (p < 0.05). In male rats, treatment altered liver, heart, and thymus coefficients (p < 0.05) and liver, adrenal gland, and heart injury were observed. The levels of 11 metabolites were altered (p < 0.05). The no-observed-adverse-effect level was not determined but would be below 7.5 g/kg in rats treated for 13 weeks. In female rats, E. sagittatum may injure the liver and pancreas and dysregulate the biosynthesis of phenylalanine, tyrosine, tryptophan, valine, leucine, and isoleucine and the metabolism of phenylalanine. In male rats, the extract may injure the liver and adrenal gland and dysregulate the biosynthesis of valine, leucine, and isoleucine and the metabolism of pyruvate.

Abstract
Despite the high prevalence of alcoholic liver disease, its identification and characterization remain poor, especially in early stages such as alcoholic fatty liver disease and alcoholic steatohepatitis. This latter implies diagnostic difficulties, few therapeutic options and unclear mechanisms of action. To elucidate the metabolic alterations and pinpoint affected biochemical pathways, alcoholic steatohepatitis was simulated in vitro by exposing HepaRG cells to ethanol (IC10, 368 mM) and tumor necrosis factor alpha (TNF-α, 50 ng/mL) for 24 h. This combined exposure was compared to solely ethanol-exposed as well as -nonexposed cells. Four different metabolomics platforms were used combining liquid chromatography, high-resolution mass spectrometry and drift tube ion mobility to elucidate both intracellular and extracellular metabolic alterations. Some of the key findings include the influence of TNF-α in the upregulation of hepatic triglycerides and the downregulation of hepatic phosphatidylethanolamines and phosphatidylcholines. S-Adenosylmethionine showed to play a central role in the progression of alcoholic steatohepatitis. In addition, fatty acyl esters of hydroxy fatty acid (FAHFA)-containing triglycerides were detected for the first time in human hepatocytes and their alterations showed a potentially important role during the progression of alcoholic steatohepatitis. Ethoxylated phosphorylcholine was identified as a potential new biomarker of ethanol exposure.

Abstract
Background Clonorchiasis is an important foodborne parasitic disease. The omics-based-techniques could illuminate parasite biology and further make innovations in the research for parasitic diseases. However, knowledge about the serum metabolic profiles and related metabolic pathways in clonorchiasis is very limited. Methods A untargeted ultra-high performance liquid tandem chromatography quadrupole time of flight mass spectrometry (UHPLC-QTOF-MS) was used to profile the serum metabolites of rats at both 4 and 8 weeks post infection (wpi) with Clonorchis sinensis (C. sinensis). Additionally, multivariate statistical analysis methods were employed to identify differential metabolites. Next, serum amino acids and phosphatidylcholines (PCs) levels were determined by targeted metabolomics analysis. Result A total of 10530 and 6560 ions were identified in ESI+ and ESI- modes. The levels of phosphatidylcholines, glycerophosphocholine and choline were significantly changed, with the shift in lipid metabolism. Significant changes were also observed in amino acids (isoleucine, valine, leucine, threonine, glutamate and glutamine). Targeted analysis showed that BCAAs (isoleucine, valine, leucine) levels significantly increased at 4 wpi and decreased at 8 wpi; threonine was increased at 8 wpi, whereas glutamate and glutamine showed a decreasing trend at 8 wpi. Additionally, the level of 17 PCs were significantly changed in infected rats. Marked metabolic pathways were involved in clonorchiasis, including glycerophospholipid metabolism, alanine, aspartate and glutamate metabolism, histidine metabolism and pyrimidine metabolism. Conclusion These results show that C. sinensis infection can cause significant changes in the rat serum metabolism, especially in amino acids and lipids. The metabolic signature together with perturbations in metabolic pathways could provide more in depth understanding of clonorchiasis and further make potential therapeutic interventions.

Abstract
Background As a nutritive feed additive, guanidine acetic acid (GAA) participates in the metabolism of energy and proteins. This study aimed to investigate the effects of GAA on growth performance, organ index, plasma and tissue free amino acid profiles, and related metabolites in finishing pigs. A total of 72 crossbred pigs (body weight 86.59 ± 1.16 kg) were randomly assigned to 1 of 4 dietary treatments (GAA0, GAA500, GAA1000, and GAA1500). They were fed the basal diets supplemented with 0, 500, 1000, or 1500 mg/kg GAA for 42 days, respectively. The growth performance and organ weight were evaluated, and the contents of crude protein, free amino acids, and metabolites in plasma and tissues were determined. Spearman correlation between plasma and tissue free amino acids and related metabolites was also analyzed. Results Growth performance in pigs was not altered by GAA (P > 0.05). The absolute and relative weight of kidneys increased (quadratic, P < 0.05). As dietary GAA concentration was increased, the contents of plasma glycine, serine, leucine, ornithine, and ratio of ornithine/arginine decreased (linear or quadratic, P < 0.05), but the contents of plasma isoleucine and taurine and the ratios of alanine/branched-chain amino acids and proline/ornithine increased quadratically (P < 0.05). The hepatic γ-amino-n-butyric acid content increased linearly and quadratically (P < 0.001), while the carnosine content decreased (quadratic, P = 0.004). The contents of renal arginine, proline, cystine, glutamate, and total amino acids (TAA) decreased quadratically (P < 0.05), but the contents of glycine (quadratic, P = 0.015) and γ-amino-n-butyric acid (linear, P = 0.008) increased. The pancreatic tryptophan content (quadratic, P = 0.024) increased, while the contents of pancreatic proline (linear, P = 0.005) and hydroxyproline (quadratic, P = 0.032) decreased in response to GAA supplementation. The contents of cardiac essential amino acids (EAA), nonessential amino acids (NEAA), and TAA in GAA1000 were higher than those in GAA1500 (P < 0.05). Supplementing with GAA linearly increased the contents of methionine, threonine, valine, isoleucine, leucine, phenylalanine, tryptophan, lysine, histidine, arginine, serine, alanine, glutamine, asparagine, tyrosine, proline, taurine, cystathionine, α-aminoadipic acid, β-aminoisobutyric acid, EAA, NEAA, and TAA in the spleen (P < 0.05). A strong Spearman correlation existed between plasma and tissue free amino acids and related metabolites. Conclusion GAA supplementation did not altered pig growth performance, but it altered plasma and tissue free amino acid profiles and the contents of related metabolites in pigs in a tissue-dependent manner.
