Abstract
Gamma-glutamyl transferase (GGT) is a marker of oxidative stress and cholestasis. Because of its low specificity, clinicians usually ignore its diagnostic value.To compare and analyze the clinical features of GGT in primary biliary cholangitis (PBC), drug-induced liver injury (DILI), alcoholic liver disease (ALD), and non-alcoholic fatty liver disease (NAFLD) from the perspective of different causes instead of the severity of the disease.We observed the distribution characteristics and the rate of abnormality of GGT in the above 4 diseases. The relationship between GGT and alanine aminotransferase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), total serum bilirubin, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol, high-density lipoprotein cholesterol was analyzed using Spearman correlation.The highest level of GGT was up to 1000.00 to 2000.00 U/L in PBC and DILI, and the highest level of GGT was more than 2000.00 U/L in ALD, yet the difference was not statistically significant (P > .05). The highest level of GGT was only about 200.00 U/L in NAFLD and was the lowest in 4 liver diseases. Also, GGT was positively correlated with ALP, TC in PBC and DILI. Also, in ALD, GGT was positively correlated with ALT, AST, ALP, TG, and TC. In NAFLD, GGT was positively correlated with ALT, AST, and TG.The abnormal GGT in PBC and cholestasis DILI was associated with cholestasis; in ALD, it was associated with oxidative stress and cholestasis, and in NAFLD, it was associated with oxidative stress. GGT levels had different characteristics in different liver diseases, which were closely related to the pathogenesis of liver diseases.

Abstract
The purpose of this study was to investigate the beneficial effects of synbiotics on liver damage, intestinal health, and muscle loss, and their relevance in rats with chronic ethanol feeding. Thirty Wistar rats fed with a control liquid diet were divided into control and synbiotics groups, which were respectively provided with water or synbiotics solution (1.5 g/kg body weight/day) for 2 weeks. From the 3rd to 8th week, the control group was divided into a C group (control liquid diet + water) and an E group (ethanol liquid diet + water). The synbiotics group was separated in to three groups, SC, ASE, and PSE. The SC group was given a control liquid diet with synbiotics solution; the ASE group was given ethanol liquid diet with synbiotics solution, and the PSE group was given ethanol liquid diet and water. As the results, the E group exhibited liver damage, including increased AST and ALT activities, hepatic fatty changes, and higher CYP2E1 expression. Intestinal mRNA expressions of occludin and claudin-1 were significantly decreased and the plasma endotoxin level was significantly higher in the E group. In muscles, beclin-1 was significantly increased in the E group. Compared to the E group, the PSE and ASE groups had lower plasma ALT activities, hepatic fatty changes, and CYP2E1 expression. The PSE and ASE groups had significantly higher intestinal occludin and claudin-1 mRNA expressions and lower muscular beclin-1 expression when compared to the E group. In conclusion, synbiotics supplementation might reduce protein expression of muscle protein degradation biomarkers such as beclin-1 in rats with chronic ethanol feeding, which is speculated to be linked to the improvement of intestinal tight junction and the reduction of liver damage.

Abstract
BACKGROUND Human epididymis protein 4 (HE4) has been identified as marker for renal fibrosis. Present study aimed to investigate the clinical significance of serum HE4 in liver fibrosis. METHODS Serum from 65 liver fibrosis patients, 68 hepatic patients without fibrosis, and 50 controls was collected respectively. Serum HE4 levels were measured by chemiluminescence immunoassay and compared among the groups. The relationships between serum HE4 levels and the clinical characteristics of liver fibrosis were also analyzed. A receiver operator characteristic curve was plotted to investigate the diagnostic efficacy of serum HE4 for liver fibrosis. Child-Pugh (C-P) score and liver fibrosis score were also evaluated. Data were analyzed by statistical software 13.0. RESULTS Serum HE4 levels were significantly higher in liver fibrosis than that of controls [105.35 (82.64, 164.18) vs 46.2 (39.9, 58.9) pmol L, P = .00] and hepatic patients without liver fibrosis [105.35 (82.64, 164.18) vs 51.00 (44.02, 65.65) pmol L, P < .01]; Serum HE4 levels in liver fibrosis patients with C-P class C were significantly higher than those with C-P class A [143.75 (106.50, 186.08) vs 81.42 (69.73, 99.26) pmol L, P = .005] and C-P class B [143.75 (106.50, 186.08) vs 113.10 (88.92, 169.50) pmol L, P = .01]; the diagnostic sensitivity and specificity of serum HE4 levels for liver fibrosis detection were 87.5% and 81.1%, at a cutoff value of 69 pmol L; Serum HE4 levels in alcoholic liver fibrosis were higher than that of liver fibrosis with hepatitis B virus infection [131.30 (100.67, 228.35) vs 89.46 (73.74, 116.45) pmol L, P < .01]. CONCLUSION Serum HE4 was closely correlated with C-P class and might be a potential marker for liver fibrosis.

Abstract
Ethanol increases iron absorption. Therefore, increased amount of iron reaches the liver, and exerts pro-oxidant effects and stimulates ferritin synthesis and hepatic stellate cell activation, promoting fibrosis and inflammation. These mechanisms would theoretically support a role of ferritin as a marker of the transition to liver cirrhosis, and, consequently, as a prognostic factor, but there is controversy regarding its behavior in alcoholics. We analyzed among 238 severe alcoholics the prognostic value of iron, ferritin, transferrin, transferrin saturation index (TSI) and total iron binding capacity (TIBC), and the relationships of these variables with liver function, proinflammatory markers (C-reactive protein (CRP), interleukin (IL)-6, IL-8, and tumor necrosis factor α), and the presence of cirrhosis. Patients showed higher serum ferritin (Z = 2.50, p = 0.031) but lower transferrin (t(264) = 4.81, p < 0.001), TIBC (t(262) = 4.44, p < 0.001), and iron (Z = 3.19, p = 0.001) values compared with 32 age- and sex-matched controls. Ferritin was related to inflammatory cytokines such as IL-8 (ρ = 0.18, p = 0.012) and to IL-6 (ρ = 0.16, p = 0.016), but not to liver function. On the contrary, cirrhotics showed lower transferrin (t(234) = 4.77, p < 0.001) and TIBC (t(232) = 4.67, p < 0.001), but higher TSI (Z = 3.35, p < 0.001) than non-cirrhotics. Transferrin, TSI, and TIBC were related to liver function impairment (marked differences among the Child's groups regarding transferrin (KW (2) = 22.83, p < 0.001), TSI (KW (2) = 15.81, p < 0.001), and TIBC (KW (2) = 21.38, p < 0.001) but only weakly to inflammation (inverse relationships between IL-6 and total iron (ρ = - 0.16, p = 0.017), TIBC (ρ = - 0.20, p = 0.002), and transferrin (ρ = - 0.20, p = 0.003). In accordance, albumin, IL-6, alcohol quitting, and TSI, in this order, were independently related to mortality, but not ferritin or iron.

Abstract
This study examined the effects of defatted mealworm fermentation extract (MWF) on alcoholic liver injury in rats. The rats were fed either a Lieber-DeCarli control (Con) or alcohol liquid diet (EtOH). The alcohol-fed rats were administered MWF (50, 100, or 200 mg/kg/day) and silymarin (200 mg/kg/day) orally for eight weeks. MWF prevented alcohol-induced hepatocellular damage by decreasing their serum aspartate transaminase, alanine transaminase, and gamma-glutamyl transpeptidase levels significantly compared to the EtOH group. MWF effectively reduced the relative hepatic weight, lipid contents, and fat deposition, along with the down-regulation of transcriptional factors and genes involved in lipogenesis compared to the EtOH group. It also enhanced the antioxidant defense system by elevating the glutathione level and glutathione reductase activity. MWF attenuated the alcohol-induced inflammatory response by down-regulating hepatic inflammation-associated proteins expression, such as phosphorylated-inhibitor of nuclear factor-kappa B-alpha and tumor necrosis factor-alpha, in chronic alcohol-fed rats. Furthermore, sequencing analysis in the colonic microbiota showed that MWF tended to increase Lactobacillus johnsonii reduced by chronic alcohol consumption. These findings suggest that MWF can attenuate alcoholic liver injury by regulating the lipogenic and inflammatory pathway and antioxidant defense system, as well as by partially altering the microbial composition.

Abstract
BACKGROUND Although the FibroTest has been validated as a biomarker to determine the stage of fibrosis in non-alcoholic fatty liver disease (NAFLD) with results similar to those in chronic hepatitis C (CHC), B (CHB), and alcoholic liver disease (ALD), it has not yet been confirmed for the prediction of liver-related death. AIM To validate the 10-year prognostic value of FibroTest in NAFLD for the prediction of liver-related death. METHOD Patients in the prospective FibroFrance cohort who underwent a FibroTest between 1997 and 2012 were pre-included. Mortality status was obtained from physicians, hospitals or the national register. Survival analyses were based on univariate (Kaplan-Meier, log rank, AUROC) and multivariate Cox risk ratio taking into account age, sex and response to anti-viral treatment as covariates. The comparator was the performance of the FibroTest in CHC, the most validated population. RESULTS 7082 patients were included; 1079, 3449, 2051, and 503 with NAFLD, CHC, CHB, and ALD, respectively. Median (range) follow-up was 6.0 years (0.1-19.3). Ten year survival (95% CI) without liver-related death in patients with NAFLD was 0.956 (0.940-0.971; 38 events) and 0.832 (0.818-0.847; 226 events; P = 0.004) in CHC. The prognostic value (AUROC / Cox risk ratio) of FibroTest in patients with NAFLD was 0.941 (0.905-0.978)/1638 (342-7839) and even higher than in patients with CHC 0.875 (0.849-0.901; P = 0.01)/2657 (993-6586). CONCLUSIONS The FibroTest has a high prognostic value in NAFLD for the prediction of liver-related death. (ClinicalTrials.gov number, NCT01927133).

Abstract
OBJECTIVE To determine the influence of isoforms of transferrin (Tf) on the detection of serum carbohydrate-deficient transferrin (CDT) by capillary electrophoresis (CE). METHODS A total of 51,17,and 65 serum samples were collected from the healthy participants,the patients with non-alcoholic liver diseases,and the patients with alcoholic liver diseases,respectively. Serum CDT was measured by CE. The genotype ofTf of the samples without a good separation was further analyzed using high resolution melting (HRM) methods. Those with suspected mutation were confirmed by sequencing. RESULTS Six samples showed incomplete separation (2 from the healthy participants,3 from the patients with non-alcoholic liver diseases,1 from the patient with alcoholic liver diseases). Of the 133 serum samples,2.3% (3/133) were detected withTf-Dchi heterozygote. But noTf-D1 andTf-B2 heterozygote were identified. CONCLUSION Tf-Dchi variant influences the measurement of carbohydrate deficientTf by CE,leading to unreliable results.

Abstract
Mild, asymptomatic elevations (less than five times the upper limit of normal) of alanine transaminase and aspartate transaminase levels are common in primary care. It is estimated that approximately 10% of the U.S. population has elevated transaminase levels. An approach based on the prevalence of diseases that cause asymptomatic transaminase elevations can help clinicians efficiently identify common and serious liver disease. The most common causes of elevated transaminase levels are nonalcoholic fatty liver disease and alcoholic liver disease. Uncommon causes include drug-induced liver injury, hepatitis B and C, and hereditary hemochromatosis. Rare causes include alpha1-antitrypsin deficiency, autoimmune hepatitis, and Wilson disease. Extrahepatic sources, such as thyroid disorders, celiac sprue, hemolysis, and muscle disorders, are also associated with mildly elevated transaminase levels. The initial evaluation should include an assessment for metabolic syndrome and insulin resistance (i.e., waist circumference, blood pressure, fasting lipid level, and fasting glucose or A1C level); a complete blood count with platelets; measurement of serum albumin, iron, total iron-binding capacity, and ferritin; and hepatitis C antibody and hepatitis B surface antigen testing. The nonalcoholic fatty liver disease fibrosis score and the alcoholic liver disease/nonalcoholic fatty liver disease index can be helpful in the evaluation of mildly elevated transaminase levels. If testing for common causes is consistent with nonalcoholic fatty liver disease and is otherwise unremarkable, a trial of lifestyle modification is appropriate. If the elevation persists, hepatic ultrasonography and further testing for uncommon causes should be considered.

Abstract
The liver disease related to chronic alcohol consumption is one of the leading causes of death for alcoholics. The efficient drug to ameliorate the alcoholic liver injury was needed urgently. The present study was performed to investigate whether artemisinin possessed the protective effect against chronic alcohol consumption. 50 male Kunming mice were divided into 5 groups: control group (C): 10ml/kg saline+10ml/kg saline, alcohol group (A): 10ml/kg 56%(v/v) alcohol+10ml/kg saline, low dose group of artemisinin (L): 10ml/kg 56%(v/v) alcohol+30mg/kg/day artemisinin, medium dose group of artemisinin (M): 10ml/kg 56%(v/v) alcohol+60mg/kg/day artemisinin, high dose group of artemisinin (H): 10ml/kg 56%(v/v) alcohol+120mg/kg/day artemisinin. Drugs were given orally every day. The general state of mice was observed and the levels of serum activities of AST and ALT were detected after treatment with drugs for 30days. Besides, the liver weight index was calculated and histopathological analysis was performed. We successfully demonstrated that treatment with high dose of artemisinin significantly decreased the elevated levels of AST (p<0.05) and ALT (p<0.01) in plasma, as well as the liver weight index (p<0.01). The loss of body weight, tissue injury, oedema and inflammatory cell infiltration in the hepatocytes were found in the A group. These symptoms were remarkably alleviated in animals treated with artemisinin. Artemisinin can inhibit the activation of NF-кB and the expression of inflammatory cytokines inducible nitric oxide synthase. Besides, it can also enhance the stability of liver cell membrane, and reduce the damage of liver cell membrane and liver cell. Artemisinin showed a protective effect against chronic alcohol poisoning and it has a great potential for the clinical application to treat the liver injury induced by alcohol.

Abstract
AIM To assess liver fibrosis (LF) in hepatitis C virus (HCV) and alcoholic liver disease (ALD), estimate health outcomes and costs of new noninvasive testing strategies
METHODS A Markov model was developed to simulate LF progression in HCV and ALD for a cohort of 40-year-old men with abnormal levels of transaminases. Three different testing alternatives were studied: a single liver biopsy; annual Enhanced liver fibrosis (ELF™) followed by liver stiffness measurement (LSM) imaging as a confirmation test if the ELF test is positive; and annual ELF test without LSM. The analysis was performed from the perspective of a university hospital in Spain. Clinical data were obtained from published literature. Costs were sourced from administrative databases of the hospital. Deterministic and probabilistic sensitivity analyses were performed.
RESULTS In HCV patients, annual sequential ELF test/LSM and annual ELF test alone prevented respectively 12.9 and 13.3 liver fibrosis-related deaths per 100 persons tested, compared to biopsy. The incremental cost-effectiveness ratios (ICERs) were respectively €13400 and €11500 per quality-adjusted life year (QALY). In ALD, fibrosis-related deaths decreased by 11.7 and 22.1 per 100 persons tested respectively with sequential ELF test/LSM and annual ELF test alone. ICERs were €280 and €190 per QALY, respectively.
CONCLUSION The use of the ELF test with or without a confirmation LSM are cost-effective options compared to a single liver biopsy for testing liver fibrosis in HCV and ALD patients in Spain.

Abstract
AIMS To document risk factors of all-cause mortality in a cohort of indigenous Australians from 23 communities of North Queensland during 1998-2006. METHODS Among 2787 indigenous adults, baseline weight, waist circumference, blood pressure, fasting glucose, lipids, gamma-glutamyl transferase, urine albumin creatinine ratio, smoking, alcohol intake and physical activity were measured in 1998-2000. Deaths were ascertained from State Registry of Deaths, hospitalization and clinical records till 2006. Mortality risk factors were assessed using a Cox proportional-hazards model. RESULTS The standardized all-cause mortality rate was 23.2/1000 person-years (95% CI 20.3-26.3/1000 pys). After adjusting for age, sex, and ethnicity, baseline plasm fasting glucose >=5.5mmol/L was associated with a 50% increased risk of death (HR 1.5, 95% CI 1.2-2.0). Albuminuria was associated with all-cause mortality with a hazards ratio of 1.4 for microalbuminuria (95% CI 1.0-1.9) and 2.6 (95% CI 1.8-3.7) for macroalbuminuria. Gamma-glutamyl transferase >=50IU was associated with an increased risk of all-cause mortality by 40% (95% CI 1.04-1.8). CONCLUSIONS Fasting glycaemia, albuminuria, and gamma-glutamyl transferase, may be a marker for all-cause mortality within this cohort.

Abstract
The association between alcoholic liver disease (ALD) and the inflammatory response remains controversial. The aim of this study was to explore this association between ALD and inflammation. We enrolled 214 male participants, who were divided into three age-matched groups: ALD (n = 135), chronic alcohol ingestion without ALD (non-ALD; n = 42), and control (n = 37). The BMI was significantly higher in the ALD group than in the non-ALD and control groups (all P = 0.000). Further, the constituent ratio of the liver inflammatory level was significantly higher in the ALD group than in the non-ALD and control groups (P = 0.002 and P = 0.000, respectively). In addition, the median serum ALT, AST, and GGT levels were significantly higher in the ALD group than in the control group (P = 0.023, P = 0.008, and P = 0.000, respectively); these levels were also significantly higher in the ALD group than in the non-ALD group (P = 0.013, P = 0.010, and P = 0.000, respectively). The median serum CRP level was significantly higher in the ALD group than in the non-ALD and control groups (P = 0.006 and P = 0.000, respectively). Further, the median serum TNF-α level was significantly lower in the ALD group than in the non-ALD and control groups (P = 0.004 and P = 0.000, respectively). The median serum sOX40L and HSP70 levels were significantly lower in the ALD group than in the control group (P = 0.008 and P = 0.018, respectively). In addition, the ALT, AST, and GGT levels were positively correlated with the CRP level (r = 0.211, P = 0.002; r = 0.220, P = 0.001 and r = 0.295, P = 0.000, respectively), and the GGT level was negatively correlated with the TNF-α (r = -0.225, P = 0.001), sOX40L (r = -0.165, P = 0.016), and HSP70 levels (r = -0.178, P = 0.009). Further, the Cr level was negatively correlated with the IL-10 level (r = -0.166, P = 0.015). Logistic regression analysis verified that the BMI (OR = 1.637, 95%CI: 1.374-1.951, P = 0.000) and GGT level were significantly higher (OR = 1.039, 95%CI: 1.020-1.059, P = 0.000) and that the TNF-α (OR = 0.998, 95%CI: 0.996-1.000, P = 0.030) and HSP70 levels were significantly lower (OR = 1.017, 95%CI: 1.003-1.031, P = 0.029) in the ALD group than in the non-ALD group. Further, the moderate-to-severe ALD patients had a significantly higher serum CRP level (Or = 1.349, 95%CI: 1.066-1.702, P = 0.013) and significantly lower HSP60 (OR = 0.965, 95%CI: 0.938-0.993, P = 0.014) and HSP70 levels (OR = 0.978, 95%CI: 0.962-0.995, P = 0.010) than the mild ALD patients. These results suggest that ALD patients may present with obesity, liver damage, and an imbalanced inflammatory immune response, mainly manifesting as decreased levels of immune inflammatory cytokines. In addition, they suggest that certain liver and kidney function parameters and ALD severity are either positively or negatively correlated with certain inflammatory cytokines. Hence, ALD patients may be at increased risks of obesity- and inflammation-related diseases. Accordingly, to control the inflammatory response, preventative measures for patients with this disease should include weight control and protection of liver and kidney function.

Abstract
BACKGROUND/AIMS This study aimed to verify the reliability of the alcoholic liver disease (ALD)/nonalcoholic fatty liver disease (NAFLD) index (ANI) for distinguishing ALD in patients with hepatic steatosis from NAFLD, and to investigate whether ANI combined with γ-glutamyl transferase (GGT) would enhance the accuracy of diagnosis in China. METHODS A hundred thirty-nine cases of fatty liver disease (FLD) were divided into two groups of ALD and NAFLD. The ANI was calculated with an online calculator. All indicators and ANI values were analyzed using statistical methods. RESULTS ANI was significantly higher in patients with ALD than in those with NAFLD (7.11 ± 5.77 vs. -3.09 ± 3.89, p < 0.001). With a cut-off value of -0.22, the sensitivity, specificity, and area under the receiver operating characteristic curve (AUROC) of diagnosed ALD cases was 87.1%, 92.5%, and 0.934 (95% confidence interval [CI], 0.879 to 0.969), respectively. The corresponding values for aspartate aminotransferase (AST)/alanine transaminase (ALT), mean corpuscular volume (MCV), and GGT were 75.29%, 72.94%, and 0.826 (95% CI, 0.752 to 0.885); 94.34%, 83.02%, and 0.814 (95% CI, 0.739 to 0.875) and 80.23%, 79.25%, and 0.815 (95% CI, 0.740 to 0.876), respectively. ANI AUROC was significantly higher than the AST/ALT, MCV, or GGT AUROCs (all p < 0.001), moreover, ANI showed better diagnostic performance. The combination of ANI and GGT showed a better AUROC than ANI alone (0.976 vs. 0.934, p = 0.016). The difference in AUROCs between AST/ALT, MCV, and GGT was not statistically significant (all p > 0.05). CONCLUSIONS ANI can help distinguish ALD from NAFLD with high accuracy; when ANI was combined with GGT, its effectiveness improved further.

Abstract
Proteomic analyses have already been used in a number of hepatological studies and provide important information. However, few reports have focused on changes in the cytoplasmic proteome. The present study therefore aimed to evaluate changes in cytoplasmic proteome of rats in response to alcoholic hepatotoxicity. Rats were fed a Liber-DeCarli liquid diet containing ethanol for four weeks. Cytoplasmic proteins except mitochondrial proteins from the livers of these animals were investigated using two-dimensional gel electrophoresis and mass spectrometry. Alcohol induced a decrease in body weight gain and an increase in alanine transaminase (ALT), cholesterol, and phospholipid levels. Histopathological observations revealed hepatic damage characterized by necrosis and fatty change in alcohol-treated group at week 2, which continues until week 4. Our proteomic analysis revealed that 25 proteins were differentially expressed in the ethanol-fed group. Of these, 12 cytoplasmic proteins are being reported for the first time. Taken together, our results provide further insights into the disease mechanism and therapeutic information of alcoholic liver disease.

Abstract
AIM: To explore the potential of contrast-enhanced computed tomography (CECT) using ExiTron nano6000 for assessment of liver lesions in mouse models.
METHODS: Three mouse models of liver lesions were used: bile duct ligation (BDL), lipopolysaccharide (LPS)/D-galactosamine (D-GalN), and alcohol. After injection with the contrast agent ExiTron nano6000, the mice were scanned with micro-CT. Liver lesions were evaluated using CECT images, hematoxylin and eosin staining, and serum aminotransferase levels. Macrophage distribution in the injury models was shown by immunohistochemical staining of CD68. The in vitro studies measured the densities of RAW264.7 under different conditions by CECT.
RESULTS: In the in vitro studies, CECT provided specific and strong contrast enhancement of liver in mice. CECT could present heterogeneous images and densities of injured livers induced by BDL, LPS/D-GalN, and alcohol. The liver histology and immunochemistry of CD68 demonstrated that both dilated biliary tracts and necrosis in the injured livers could lead to the heterogeneous distribution of macrophages. The in vitro study showed that the RAW264.7 cell masses had higher densities after LPS activation.
CONCLUSION: Micro-CT with the contrast agent ExiTron nano6000 is feasible for detecting various liver lesions by emphasizing the heterogeneous textures and densities of CECT images.

METHODS: Male Wistar rats weighing 200-230 g were subjected to a 70% partial hepatectomy (PH); they were then divided into three groups (groups 1-3). During the experiment, animals in group 1 drank only water. The other two groups (2-3) drank an aqueous solution of EtOH (40%, v/v). Additionally, rats in group 3 received a Gs extract daily at a dose of 300 mg/kg body weight intragastically. Subsequently, to identify markers of liver damage in serum, alanine aminotransferase, aspartate aminotransferase, albumin and bilirubin were measured by colorimetric methods. Glucose, triglyceride and cholesterol concentrations were also determined. In addition, oxidative damage was estimated by measuring lipid peroxidation [using thiobarbituric-acid reactive substances (TBARS)] in both plasma and the liver and by measuring the total concentration of antioxidants in serum and the total antioxidant capacity in the liver. In addition, a liver mass gain assessment, total DNA analysis and a morpho-histological analysis of the liver from animals in all three groups were performed and compared. Finally, the number of deaths observed in the three groups was analyzed.
RESULTS: Administration of the Geranium shiedeanum extract significantly reduced the unfavorable effect of ethanol on liver regeneration (restitution liver mass: PH-EtOH group 60.68% vs PH-Gs-EtOH group 69.22%). This finding was congruent with the reduced levels of hepatic enzymes and the sustained or increased levels of albumin and decreased bilirubin in serum. The extract also modified the metabolic processes that regulate glucose and lipid levels, as observed from the serum measurements. Lower antioxidant levels and the liver damage induced by EtOH administration appeared to be mitigated by the extract, as observed from the TBARs (PH-EtOH group 200.14 mmol/mg vs PH-Gs-EtOH group 54.20 mmol/mg; P < 0.05), total status of antioxidants (PH-EtOH group 1.43 mmol/L vs PH-Gs-EtOH group 1.99 mmol/L; P < 0.05), total antioxidant capacity values, liver mass gain and total DNA determination (PH-EtOH group 4.80 mg/g vs PH-Gs-EtOH 9.10 mg/g; P < 0.05). Overall, these processes could be related to decreased mortality in these treated animals.
CONCLUSION: The administered extract showed a hepatoprotective effect, limiting the EtOH-induced hepatotoxic effects. This effect can be related to modulating oxido-reduction processes.

Abstract
Several studies have reported the relationship between alcoholic liver disease (ALD) and carotid intima-media thickness (CIMT). Few studies, however, have investigated the causes of CIMT thickening in patients with ALD. The authors explored the causes of CIMT thickening in patients with ALD. The authors enrolled 152 patients who were stratified into groups: nonthickening CIMT with ALD (group A); thickening CIMT with ALD (group B); nonthickening CIMT without ALD (group C); and thickening CIMT without ALD (group D). The CIMT was significantly different between patients with and without ALD (χ 2= 3.875, P = 0.049). The patients in groups A, B, and C were significantly younger than group D (P = 0.001, 0.036, and 0.001, respectively). The body mass indexes (BMI) in groups A and B were significantly higher than in group C (P = 0.000 and 0.007, respectively). The blood glucose levels in groups B and D were significantly higher than in group C (P = 0.016 and 0.018, respectively). The blood uric acid levels in group B were significantly higher than in groups A, C, and D (P = 0.009, 0.000, and 0.003, respectively). The blood uric acid in group A was significantly higher than in group C (P = 0.002). The serum total cholesterol (TC) levels of patients in group B were significantly higher than in groups A and C (P = 0.027 and 0.000, respectively) and the serum TC level in group A was significantly higher than in group C (P = 0.048). The serum triglyceride (TG) levels in groups A and B were significantly higher than in group C (P = 0.027 and 0.000, respectively). The serum of very low-density lipoprotein (VLDL) levels in group B were significantly higher than in group C (P = 0.000). Although a comparison of the low-density lipoprotein (LDL) and high-density lipoprotein (HDL) serum levels among the 4 groups indicated no changes. The serum LDL levels in group B were significantly higher than in group A (P = 0.008). No significant differences were observed among the groups with respect to serum homocysteine, C-reactive protein (CRP), interleukin-6 (IL-6), malondialdehyde (MDA), superoxide dismutase (SOD), soluble OX40 ligand (sOX40L), or heat shock protein (HSP) 60 or 70. Alcoholic liver disease may result in CIMT thickening. Carotid intima-media thickness is associated with age and metabolic factors in patients with ALD. In addition, ALD might promote the premature occurrence of CIMT thickening. The thickening of carotid artery intima thickness, however, is not associated with cytokine profiles, oxidative balance, or immune responses in patients with ALD.

Abstract
Objectives Mechanisms of immune regulation in alcoholic liver disease (ALD) are still unclear. The aim of our study was to determine an impact of Th17 / regulatory T (Treg) cells balance and its corresponding cytokine profile on the ALD outcome. Possible gender-related differences in the alcohol-induced inflammatory response were also assessed. Materials and Methods 147 patients with ALD were prospectively recruited, assigned to subgroups based on their gender, severity of liver dysfunction and presence of ALD complications at admission, and followed for 90 days. Peripheral blood frequencies of Th17 and Treg cells together with IL-1beta, IL-6, IL-17A, IL-23, and TGF-beta1 levels were investigated. Flow cytometry was used to identify T cell phenotype and immunoenzymatic ELISAs for the corresponding cytokine concentrations assessment. Multivariable logistic regression was applied in order to select independent predictors of advanced liver dysfunction and the disease complications. Results IL-17A, IL-1beta, IL-6 levels were significantly increased, while TGF-beta1 decreased in ALD patients. The imbalance with significantly higher Th17 and lower Treg frequencies was observed in non-survivors. IL-6 and TGF-beta1 levels differed in relation to patient gender in ALD group. Concentrations of IL-6 were associated with the severity of liver dysfunction, development of ALD complications, and turned out to be the only independent immune predictor of 90-day survival in the study cohort. Conclusions We conclude that IL-6 revealed the highest diagnostic and prognostic potential among studied biomarkers and was related to the fatal ALD course. Gender-related differences in immune regulation might influence the susceptibility to alcohol-associated liver injury.

Abstract
Inflammation and intestinal permeability are believed to be paramount features in the development of alcohol-related liver damage. We aimed to assess the impact of 3 surrogate markers of inflammation (anemia, fibrinogen, and ferritin levels) on mid-term mortality of patients with alcohol dependence. This longitudinal study included patients with alcohol dependence admitted for hospital detoxification between 2000 and 2010. Mortality was ascertained from clinical charts and the mortality register. Associations between markers of inflammation and all-cause mortality were analyzed with mortality rates and Cox proportional hazards regression models. We also performed a subgroup analysis of mortality rates in patients with anemia, based on their mean corpuscular volume (MCV). We included 909 consecutive patients with alcohol dependence. Patients were mostly male (80.3%), had a median age of 44 years (interquartile range [IQR]: 38-50), and upon admission, their median alcohol consumption was 192 g/day (IQR: 120-265). At admission, 182 (20.5%) patients had anemia; 210 (25.9%) had fibrinogen levels >4.5 mg/dL; and 365 (49.5%) had ferritin levels >200 ng/mL. At the end of follow-up (median 3.8 years [IQR: 1.8-6.5], and a total of 3861.07 person-years), 118 patients had died (12.9% of the study population). Cox regression models showed that the presence of anemia at baseline was associated with mortality (hazard ratio [HR]: 1.67, 95% confidence interval [CI]: 1.11-2.52, P < 0.01); no associations were found between mortality and high fibrinogen or high ferritin levels. A subgroup of patients with anemia was analyzed and compared to a control group of patients without anemia and a normal MCV. The mortality ratios of patients with normocytic and macrocytic anemia were 3.25 (95% CI: 1.41-7.26; P < 0.01) and 3.39 (95% CI: 1.86-6.43; P < 0.01), respectively. Patients with alcohol dependence admitted for detoxification had an increased risk of death when anemia was present at admission. More accurate markers of systemic inflammation are needed to serve as prognostic factors for poor outcomes in this subset of patients.

Abstract
Liverubin™ is an available drug in the Indian market that contains silymarin, the major active complex extracted from the medicinal plant milk thistle (Silybum marianum L.). The study retrospectively tracked and analyzed the data of 602 patients, out of which 230 were alcohol induced; 131 with alcohol-induced liver damage (ALD), 13 with liver cirrhosis, and 86 with fatty liver; to assess the effects of water soluble Silymarin (Liverubin™) on important hepatic biochemical parameters. The data was collected from 32 major cities treated by 72 physicians across India who were observed for the specified treatment duration of 11 months. Data was analyzed by using descriptive statistics. At the end of the treatment the hepatic biochemical profile was appreciably improved: the mean % of change in the levels of important hepatic biochemical parameters was observed as follows: total bilirubin 63.48% (direct bilirubin: 64.96%; indirect bilirubin: 61.63%). The serum SGOT and SGPT changed at a mean % of 65.43 and 69.31 respectively while serum alkaline phosphatase was changed at a mean % rate of 39.81. Liverubin™ proved to be safe & well-tolerated among the studied population and no significant treatment related adverse events were reported during the study. Liverubin™ treatment is found to bring about effective lowering of abnormally elevated hepatic biochemical parameters. Liverubin™, water soluble active Silymarin, in the popularly prescribed doses of 140-mg tid is observed to be a promising safe and effective drug in cases of alcoholic liver disease.

Abstract
AIM: To evaluate protective effects of Chunggan extract (CGX), a traditional herbal formula, under 4 wk of alcohol consumption-induced liver injury.
METHODS: Male Sprague-Dawley Rats were orally administered 30% ethanol daily for 4 wk with or without CGX. The pharmaceutical properties were assessed through liver enzymes, histopathology, fibrogenic cytokines, and alcohol metabolism in hepatic tissues as well as by in vitro experiment using HSC-T6 cells.
RESULTS: Four weeks of alcohol consumption notably increased liver enzymes and malondialdehyde levels in serum and hepatic tissue. CGX not only prevented the collagen deposition determined by histopathology and hydroxyproline content, but also normalized transforming growth factor-beta, platelet-derived growth factor-beta and connective tissue growth factor at the gene expression and protein levels in liver tissue. Moreover, CGX treatment also significantly normalized the abnormal changes in gene expression profiles of extracellular matrix proteins, matrix metalloproteinase and their inhibitors, alcohol metabolism, and inflammatory reactions. In the acetaldehyde-stimulated HSC-T6 cells, CGX considerably inhibited collagen production and normalized fibrogenic cytokines in both gene expression and protein levels.
CONCLUSION: The present study evidenced that CGX has hepatoprotective properties via modulation of fibrogenic cytokines and alcohol metabolism in alcoholic liver injury.

Abstract
Alcoholic liver disease (ALD) is the most common liver disease in the Western world. For many reasons, it is underestimated and underdiagnosed. An early diagnosis is absolutely essential since it (1) helps to identify patients at genetic risk for ALD; (2) can trigger efficient abstinence namely in non-addicted patients; and (3) initiate screening programs to prevent life-threatening complications such as bleeding from varices, spontaneous bacterial peritonitis or hepatocellular cancer. The two major end points of ALD are alcoholic liver cirrhosis and the rare and clinically-defined alcoholic hepatitis (AH). The prediction and early diagnosis of both entities is still insufficiently solved and usually relies on a combination of laboratory, clinical and imaging findings. It is not widely conceived that conventional screening tools for ALD such as ultrasound imaging or routine laboratory testing can easily overlook ca. 40% of manifest alcoholic liver cirrhosis. Non-invasive methods such as transient elastography (Fibroscan), acoustic radiation force impulse imaging or shear wave elastography have significantly improved the early diagnosis of alcoholic cirrhosis. Present algorithms allow either the exclusion or the exact definition of advanced fibrosis stages in ca. 95% of patients. The correct interpretation of liver stiffness requires a timely abdominal ultrasound and actual transaminase levels. Other non-invasive methods such as controlled attenuation parameter, serum levels of M30 or M65, susceptometry or breath tests are under current evaluation to assess the degree of steatosis, apoptosis and iron overload in these patients. Liver biopsy still remains an important option to rule out comorbidities and to confirm the prognosis namely for patients with AH.

Abstract
Alcohol is a hepatotoxin that is commonly consumed worldwide and is associated with a spectrum of liver injury including simple steatosis or fatty liver, alcoholic hepatitis, fibrosis, and cirrhosis. Alcoholic liver disease (ALD) is a general term used to refer to this spectrum of alcohol-related liver injuries. Excessive or harmful alcohol use is ranked as one of the top five risk factors for death and disability globally and results in 2.5 million deaths and 69.4 million annual disability adjusted life years. All patients who present with clinical features of hepatitis or chronic liver disease or who have elevated serum elevated transaminase levels should be screened for an alcohol use disorder. The diagnosis of ALD can generally be made based on history, clinical and laboratory findings. However, the diagnosis of ALD can be clinically challenging as there is no single diagnostic test that confirms the diagnosis and patients may not be forthcoming about their degree of alcohol consumption. In addition, clinical findings may be absent or minimal in early ALD characterized by hepatic steatosis. Typical laboratory findings in ALD include transaminase levels with aspartate aminotransferase greater than alanine aminotransferase as well as increased mean corpuscular volume, gamma-glutamyltranspeptidase, and IgA to IgG ratio. In unclear cases, the diagnosis can be supported by imaging and liver biopsy. The histological features of ALD can ultimately define the diagnosis according to the typical presence and distribution of hepatic steatosis, inflammation, and Mallory-Denk bodies. Because of the potential reversible nature of ALD with sobriety, regular screening of the general population and early diagnosis are essential.

Abstract
Alcohol use disorders represent a heterogeneous spectrum of clinical manifestations that have been defined by the Diagnostic and Statistical Manual of Mental Disorders-5. Excessive alcohol intake can lead to damage of various organs, including the liver. Alcoholic liver disease includes different injuries ranging from steatosis to cirrhosis and implicates a diagnostic assessment of the liver disease and of its possible complications. There is growing interest in the possible different tools for assessing previous alcohol consumption and for establishing the severity of liver injury, especially by non-invasive methods.

Abstract
Alcohol-related disorders are one of the challenging current health problems with medical, social, and economic consequences. Endotoxemia, oxidative stress, and release of a variety of inflammatory molecules are established mediators in alcoholic liver injury (ALD). Probiotics like L. plantarum though were reported to attenuate ALD, their in vivo health benefits are limited by their survival and sustenance in the adverse gut conditions. Therefore, to enhance their in vivo performance, chitosan coated alginate beads entrapping L. plantarum were prepared, characterized, and evaluated for their efficacy against ALD in rats. Following chronic alcohol exposure, rats developed endotoxemia, showed enhanced levels of liver enzyme markers, NF-κB levels, and increased cytokines such as TNF- α and IL12/p40 subunit, and reflected significant histological changes in the intestine and liver. However, cosupplementation with double layered microencapsulated probiotic significantly (P < 0.05) reduced the levels of endotoxemia, serum transaminases, NF-κB, and cytokines complemented with restoration of normal histoarchitecture of the intestine and liver. It is being documented here for the first time that the probiotics have the potential to inhibit IL-12/p40 subunit which is a recently explored potential marker for developing novel therapeutic agents. This study reveals that microencapsulation of probiotics may offer a biopharmacological basis for effective management of ALD.

Abstract
BACKGROUND Plasma and hepatic lipid abnormalities are frequent in hepatitis C infected individuals. METHODS Plasma lipid and medical records profiles were prospectively obtained in 130 consecutive individuals seen by a single hepatologist in a university liver disease clinic. The relationships between viral load, genotype, plasma lipid fractions, HDL, LDL particle number and particle size were examined. RESULTS Of 130 individuals studied, 74 had hepatitis C while 15 had NAFLD/NASH and 30 had alcohol related liver disease. The LDL particle number and LDL-C levels did not differ between those with and without hepatitis C although the number of small LDL particles was greater in those with hepatitis C infection. The HDL-C and total cholesterol levels were greater in those without hepatitis C than those with hepatitis C (P = 0.009). In contrast, the serum triglyceride level was greater in the hepatitis C viral group (P = 0.013). Importantly, the hepatitis C viral load regardless of the genotype correlated directly with the triglyceride and VLDL levels with r values of 0.73 and 0.84, respectively. CONCLUSIONS There are: (1) important differences in lipid classes, number and the size of lipid particles exist between hepatitis C virus infected and noninfected liver disease groups, (2) the serum total triglyceride and the LDL levels correlate significantly with the hepatitis C viral load and, (3) Serum triglyceride level may play an important role in viral replication. These data further suggest that therapies directed at lowering plasma triglyceride levels may enhance the efficacy of current antiviral treatment regimens.

Abstract
Parameters reflecting oxidative stress (OS) have been studied in 37 patients with alcoholic liver disease (ALD) during admission to the hospital and 2 weeks after the beginning of therapy. The patients were divided into 3 groups: alcoholic hepatitis (AH), alcoholic cirrhosis with hepatic insufficiency (the group C with Child-Paquet) and terminal stage patients (they subsequently died). All patients were characterized by a significant increase in plasma products of lipid peroxidation (conjugated diene and malondialdehyde) and decrease of the ceruloplasmin level. The coefficient K OS significantly exceeded normal values both on admission and after the 2-week course of traditional treatment. This suggests an important role of the OS with ALD.

Abstract
A 74-year-old woman with a past medical history of diabetes, hypertension, and alcohol abuse was brought to the emergency department and subsequently admitted to the intensive care unit with an altered mental status and weakness. Laboratories revealed acute renal failure (BUN 15 mg/dL, creatinine 2.5 mg/dL), elevated serum transaminase (AST of 83 IU/L), hyperammonemia (187 ug/dL), and marked normocytic anemia requiring transfusion of three units of packed red cells (hemoglobin 4.3 g/dL; hematocrit 13.1%). Blood ethanol level at the time of admission was less than 5 mg/dL, and full urine toxicology was negative. Alcohol abuse was reported to consist of, on average, "one pint of gin per day." Her hospital course was nine days and included complete inotropic blood pressure support and intubation. On the ninth day, she was declared dead, and authorization for an unrestricted autopsy was granted by the coroner. At autopsy, two liters of serous ascitic fluid was drained from the peritoneal cavity, and non-ruptured, distended varices were identified at the gastroesophageal junction. Additional findings included changes compatible with hypertensive cardiovascular disease, including hypertrophy of the interventricular cardiac septum and glomerulosclerosis along with renal atrophy. The liver weighed 1,300 grams (normal 1,475 gm±362) and was markedly discolored yellow-tan. Its parenchyma was more firm than usual. Representative microscopic sections from the decedent's liver are shown in the image below.

Abstract
CONTEXT Fatty liver is the first stage of alcoholic damage which is reversible with abstinence from alcohol. Mangiferin (MF) showed potent scavenging activity on diphenyl-1-picrylhydrazyl radicals which stimulate liver regeneration in various liver injuries. OBJECTIVE Although, MF shows hepatoprotection against various liver disorders but due to rapid clearance and limited solubility in lipoid environment, there is problem of its poor absorption from intestine hence poor bioavailability. Owing to which there is a need to develop MF herbosomes to resolve the problem of poor bioavailability to enhance the therapeutic potential. METHODS Successfully prepared MF herbosomes through complexation with phospholipids were characterized by physicochemical, chromatography, spectroscopy (differential scanning calorimetry (DSC), infrared (IR), and nuclear magnetic resonance (NMR)), ex vivo absorption using everted small intestine sac technique and in vivo studies using ethanol inducing hepatotoxicity in albino rats and comparing the results against plain MF. RESULTS Ex vivo study showed significant increased absorption of MF from prepared MF herbosomes as compared to plain MF. The hepatoprotective potential of MF herbosomes evaluated by in vivo study revealed significantly decreased levels of serum glutamate oxaloacetate transminase (SGOT), serum glutamate pyruvate transminase (SGPT), total bilirubin, and alkaline phosphatase (ALP) in MF herbosomes as compared to plain MF. MF herbosomes also showed significantly decreased level of malonyl dehydrogenase along with increased levels of reduced glutathione, superoxide dismutase (SOD) and catalase as compared to plain MF which was also comparable to the standard drug, silymarin (SL). CONCLUSION The above mentioned results showed that hepatoprotective and antioxidant potency of MF enhanced due to the preparation of its herbosomes.

Abstract
Clinical studies have demonstrated that alcoholics have a lower dietary zinc intake compared to health controls. The present study was undertaken to determine the interaction between dietary zinc deficiency and ethanol consumption in the pathogenesis of alcoholic liver disease. C57BL/6N mice were subjected to 8-week feeding of 4 experimental liquid diets: (1) zinc adequate diet, (2) zinc adequate diet plus ethanol, (3) zinc deficient diet, and (4) zinc deficient diet plus ethanol. Ethanol exposure with adequate dietary zinc resulted in liver damage as indicated by elevated plasma alanine aminotransferase level and increased hepatic lipid accumulation and inflammatory cell infiltration. Dietary zinc deficiency alone increased hepatic lipid contents, but did not induce hepatic inflammation. Dietary zinc deficiency showed synergistic effects on ethanol-induced liver damage. Dietary zinc deficiency exaggerated ethanol effects on hepatic genes related to lipid metabolism and inflammatory response. Dietary zinc deficiency worsened ethanol-induced imbalance between hepatic pro-oxidant and antioxidant enzymes and hepatic expression of cell death receptors. Dietary zinc deficiency exaggerated ethanol-induced reduction of plasma leptin, although it did not affect ethanol-induced reduction of white adipose tissue mass. Dietary zinc deficiency also deteriorated ethanol-induced gut permeability increase and plasma endotoxin elevation. These results demonstrate, for the first time, that dietary zinc deficiency is a risk factor in alcoholic liver disease, and multiple intrahepatic and extrahepatic factors may mediate the detrimental effects of zinc deficiency.

Abstract
One of the molecular mechanisms of alcohol induced toxicities is mediated by oxidative stress. Hence our studies were focused on the effect of thiamine (antioxidant) in the reversal of alcohol induced toxicity and comparison of the reversal with abstinence. Administration of ethanol at a dose of 4 g/kg body wt/day for 90 days to Sprague Dawley rats manifested chronic alcohol induced toxicity evidenced by decreased body weight, an increase in liver-body weight ratio, increase in activities of serum and liver aspartate transaminase (AST), alanine transaminase (ALT), gamma-glutamyl transpeptidase (GGT); decrease in the activities of superoxide dismutase, catalase, glutathione peroxidase and glutathione reductase in the liver and brain. The levels of inflammatory markers, fibrosis markers and DNA fragmentation were also elevated in the serum, liver and brain. After ethanol administration for 90 days, the reversal of the alcohol induced toxicity was studied by supplementing thiamine at a dose of 25 mg/100 g body wt/day. Duration of the reversal study was 30 days. The activities of AST, ALT, GGT, scavenging enzymes as well as markers of inflammation and fibrosis in serum, liver and brain were reversed to a certain extent by thiamine. Changes in neurotransmitter levels in brain were also reversed by thiamine supplementation. DNA damage was decreased and DNA content increased in thiamine supplemented group compared to abstinence group showing a faster regeneration. In short, histopathological and biochemical evaluations indicate that thiamine supplemented abstinent rats made a faster recovery of hepatic and neuronal damage than in the abstinence group.

Abstract
Background Chronic ingestion of ethanol increases acetaldehyde and leads to the production of acetaldehyde-derived advanced glycation end-products (AA-AGE). We evaluated the toxicity of AA-AGE on hepatocytes and studied the role of AA-AGE in the pathogenesis of alcoholic liver disease (ALD). Methods Rat hepatocyte cultures were treated with N-ethyllysine (NEL) or AA-AGE and the cell viability was evaluated using MTT assay. Male Wistar rats were fed with liquid diet containing 5% ethanol for 8 weeks following normal diet for another 12 weeks. A group of animals was sacrificed at 4th, 6th, and 8th week and the remaining animals at 12th, 14th, 16th, 18th, and 20th week. The liver sections were stained for AA-AGE and 4-hydroxy-2-nonenal (4-HNE). Liver biopsy obtained from ALD patients was also stained for AA-AGE and 4-HNE. Results Hepatocyte viability was significantly reduced in cultures treated with AA-AGE compared to NEL treated or control cultures. Severe fatty degeneration was observed during chronic administration of ethanol increasing from 4–8 weeks. The staining of AA-AGE and 4-HNE was correlated with the degree of ALD in both rat and human. In rats, hepatic fatty degeneration was completely disappeared and the staining for both AA-AGE and 4-HNE returned to normal at 12th week of abstinence. Staining for AA-AGE and 4-HNE was completely absent in normal human liver. Conclusions The data demonstrated that AA-AGE is toxic to hepatocytes, but not NEL. Chronic ethanol ingestion produces AA-AGE and reactive oxygen species that contribute to the pathogenesis of ALD. Abstinence of alcohol results in complete disappearance of both AA-AGE and 4-HNE along with fatty degeneration suggesting that AA-AGE plays a significant role in the pathogenesis of ALD.

Abstract
Retinoids (vitamin A and its metabolites) are essential micronutrients that regulate many cellular processes. Greater than 70% of the body's retinoid reserves are stored in the liver as retinyl ester (RE). Chronic alcohol consumption induces depletion of hepatic retinoid stores, and the extent of this has been correlated with advancing stages of alcoholic liver disease. The goal of this study was to analyze the mechanisms responsible for depletion of hepatic RE stores by alcohol consumption A change in the fatty-acyl composition of RE in alcohol-fed mice was observed within two weeks after the start of alcohol consumption. Specifically, alcohol-feeding was associated with a significant decline in hepatic retinyl palmitate levels; however, total RE levels were maintained by a compensatory increase in levels of usually minor RE species, particularly retinyl oleate. Our data suggests that alcohol feeding initially stimulates a futile cycle of RE hydrolysis and synthesis, and that the change in RE acyl composition is associated with a change in the acyl composition of hepatic phosphatidylcholine. The alcohol-induced change in RE acyl composition was specific to the liver, and was not seen in lung or white adipose tissue. This shift in hepatic RE fatty acyl composition is a sensitive indicator of alcohol consumption and may be an early biomarker for events associated with the development of alcoholic liver disease.

Abstract
Objective Impaired liver regeneration is associated with a poor outcome in patients with decompensated alcoholic liver disease (ALD). We assessed whether autologous bone marrow mononuclear cell transplantation (BMMCT) improved liver function in decompensated ALD. Design 58 patients (mean age 54 yrs; mean MELD score 19, all with cirrhosis, 81% with alcoholic steatohepatitis at baseline liver biopsy) were randomized early after hospital admission to standard medical therapy (SMT) alone (n = 30), including steroids in patients with a Maddrey’s score ≥32, or combined with G-CSF injections and autologous BMMCT into the hepatic artery (n = 28). Bone marrow cells were harvested, isolated and reinfused the same day. The primary endpoint was a ≥3 points decrease in the MELD score at 3 months, corresponding to a clinically relevant improvement in liver function. Liver biopsy was repeated at week 4 to assess changes in Ki67+/CK7+ hepatic progenitor cells (HPC) compartment. Results Both study groups were comparable at baseline. After 3 months, 2 and 4 patients died in the BMMCT and SMT groups, respectively. Adverse events were equally distributed between groups. Moderate alcohol relapse occurred in 31% of patients. The MELD score improved in parallel in both groups during follow-up with 18 patients (64%) from the BMMCT group and 18 patients (53%) from the SMT group reaching the primary endpoint (p = 0.43 (OR 1.6, CI 0.49–5.4) in an intention to treat analysis. Comparing liver biopsy at 4 weeks to baseline, steatosis improved (p<0.001), and proliferating HPC tended to decrease in both groups (−35 and −33%, respectively). Conclusion Autologous BMMCT, compared to SMT is a safe procedure but did not result in an expanded HPC compartment or improved liver function. These data suggest either insufficient regenerative stimulation after BMMCT or resistance to liver regenerative drive in patients with decompensated alcoholic cirrhosis.

Abstract
Alcoholic liver disease (ALD) is consequence of alcohol addiction, that increase morbidity and mortality of those group of patients. Induction of the inflammatory process in alcohol injured liver is a turning point in ALD, can cause acute liver damage symptoms or cirrhosis with increase of hepatic fibrosis intensity and portal hypertension. Osteopontin (OPN)--a protein associated with early inflammatory process and remodeling of damaged tissues with intensification of hepatic fibrogenesis process, is considered to be a biomarker of hepatic inflammation and fibrosis. A group of 12 patients with mean age--44 years, mean alcohol addiction time--16 years, hospitalized because of alcohol withdrawal symptoms were examined in the preliminary report. ALD was diagnosed in all patients, steatosis--in 4, inflammatory--in 3, cirrhosis--in 5. Control group were 19 healthy patients with no alcohol addiction and liver disease in medical history. Serum OPN level was measured by ELISA method using reagents from Raybiotech. Serum OPN level in control group ranged 0-35,955 pg/ml, in examined group ranged 0-338,280 pg/ml. OPN levels in serum of patients with hepatic steatosis were under limit of detection (< 50 pg/ml). OPN serum level increase was correlated to ALD progression. The highest OPN levels (> 100,000 pg/ml) were observed in patients with symptoms of the liver decompensation due to severe hepatitis and advanced cirrhosis.

Abstract
UNLABELLED MicroRNAs are fine tuners of diverse biological responses and are expressed in various cell types of the liver. Here we hypothesized that circulating microRNAs (miRNAs) may serve as biomarkers of liver damage and inflammation. We studied miRNA-122, which is abundant in hepatocytes, and miR-155, -146a, and -125b, which regulate inflammation in immune cells in mouse models of alcoholic liver disease (ALD), drug (acetaminophen, APAP)-induced liver injury (DILI), and Toll-like receptor (TLR) 9+4 ligand-induced inflammatory cell-mediated liver damage. We found that serum/plasma miR-122 correlated with alanine aminotransferase (ALT) increases in the liver damage caused by alcohol, APAP, and TLR9 (CpG)+4 (LPS) ligands. MiR-155, a regulator of inflammation, was increased in serum/plasma in alcoholic and inflammatory liver injury. Alcohol failed to increase serum miR-122 in TLR4-deficient and p47phox-deficient mice that were protected from ALD. We found the most robust increase in plasma miR-122 in DILI and it correlated with the highest ALT levels. Consistent with the massive inflammatory cell infiltration in the liver, plasma miR-155 and miR-146a were significantly elevated after CpG+LPS administration. We show for the first time that, depending on the type of liver injury, circulating miRNAs are associated either with the exosome-rich or protein-rich compartments. In ALD and in inflammatory liver injury, serum/plasma miR-122 and miR-155 were predominantly associated with the exosome-rich fraction, whereas in DILI/APAP injury these miRNAs were present in the protein-rich fraction. CONCLUSION Our results suggest that circulating miRNAs may serve as biomarkers to differentiate between hepatocyte injury and inflammation and the exosome versus protein association of miRNAs may provide further specificity to mechanisms of liver pathology.

Abstract
Ethanol metabolism is known to induce overwhelming production of reactive oxygen species (ROS) and also to cause associated immune dysfunction. Several interventional agents of plant origin, in particular fruits and vegetables have been used to counteract these alterations induced by ethanol. In this study, we investigated the efficacy of dietary feeding of skin and flesh of grapes (Vitis vinifera L.) on the alterations in immune and vascular functions in mice with liver abnormalities induced by chronic ethanol consumption. Results revealed that feeding of both grape skin and flesh (2.5 g/kg body wt/day) effectively attenuated the oxidative stress and alterations in immune function and angiogenesis induced by chronic ethanol consumption (1.6 g/kg body wt/day for 12 weeks) in mice. The antioxidant actions of the grape skin and flesh as observed in this study might be attributed to the polyphenols present in the grapes.

Abstract
OBJECTIVE To explore attenuation and mechanism of endoplasmic reticulum stress (ERS)-mediated hepatocyte apoptosis in rats with alcohol-induced liver injury by Qinggan Huoxue Recipe (QGHXR) and its disassembled formulas (Qinggan Recipe and Huoxue Recipe respectively). METHODS A rat model of chronic alcoholic liver injury was successfully established using a compound reagent of alcohol, corn oil, and pyrazol. The modeled rats were randomly divided into the model group, the QGHXR group, the Qinggan Recipe (QGR) group, and the Huoxue Recipe group (HXR). The CCl4 control group and the normal control group were also set up. There were ten rats in each group. All rats of modeled groups were gastrogavaged with alcohol compound reagent every morning. Rats in the QGHXR group (at the daily dose of 9. 5 g/kg, QGR group (at the daily dose of 3.0 g/kg), and HXR group (at the daily dose of 6.5 g/kg) were administered with corresponding medicines by gastrogavage every afternoon. Equal volume of normal saline was given to rats of the model group by gastrogavage. CCl4 was intraperitoneally injected at the dose of 0.3 mL/kg to rats in the CCl4 control group, once per week. Normal saline was given to rats in the normal control group by gastrogavage. The treatment was lasted for two weeks. Pathological changes of the liver were observed by histopathology. Serum total homocysteine (tHCY) level was detected by ELISA. The hepatocyte apoptosis rate was detected using flow cytometry. The gene and protein expressions of eukaryotic translation initiation factor 2 alpha (elF-2alpha), phosphorylation elF-2alpha (pelF-2alpha), glucose-regulated protein 78 (GRP78), and Caspase-3 in the liver were examined using Real-time PCR and Westen blot respectively. RESULTS Compared with the normal control group, typical pathological changes of chronic alcoholic liver injury such as steatosis, inflammation, and even fibrosis occurred in model rats. The hepatocyte apoptosis obviously increased, with the apoptosis rate reaching the five-fold of that in normal rats. Besides, early apoptosis dominated. The serum tHCY level significantly increased. The expressions of p-elF-2alpha, GRP78, and Caspase-3 protein obviously increased (P < 0.01). Expressions of GRP78 and Caspase-3 mRNA significantly increased (P < 0.05, P < 0.01). Compared with the model group, the degrees of the liver injury and the hepatocyte apoptosis in the QGHXR group, the QGR group, and the HXR group were significantly alleviated. The serum tHCY level was significantly lowered. The protein expressions of p-elF-2a, GRP78, and Caspase-3 obviously decreased (P < 0.01). mRNA expressions of GRP78 and Caspase-3 obviously decreased in the QGHXR group (P < 0.05, P < 0.01). Only GRP78 mRNA expression obviously decreased in the QGR group (P < 0.05). CONCLUSION QGHXR and its disassembled formulas could attenuate ERS-mediated hepatocyte apoptosis in alcohol-induced liver injury rats by lowering the serum tHCY level and expressions of ERS apoptosis correlated factors.

Abstract
Background Quantification of hepatotocyte death is useful to evaluate the progression of alcoholic liver diseases. Our aims were to quantify and correlate the circulating levels of Cytokeratin 18 (CK18) and its caspases-generated fragment to disease severity in heavy alcoholics. Methodology/Principal Findings CK18 and CK18-fragment were evaluated in the serum of 143 heavy alcoholics. Serum levels of markers of hepatocyte death (CK18), apoptosis (CK18 fragment) and necrosis (CK18 -CK18 fragment) increased in patients with severe fibrosis compared to patients with mild fibrosis. These markers strongly correlated with Mallory-Denk bodies, hepatocyte ballooning, fibrosis and with hepatic TNFα and TGFβ assessed in the liver of 24 patients. Elevated levels of serum hepatocyte death and apoptotic markers were independent risk factors in predicting severe fibrosis in a model combining alkaline phosphatase, bilirubin, prothrombin index, hyaluronate, hepatocyte death and apoptotic markers. The level of markers of hepatocyte death and apoptosis had an area under the receiving operator curve that predicted severe fibrosis of 0.84 and 0.76, respectively. Conclusion/Significance Death of hepatocytes can be easily evaluated with serum markers and correlated with severe fibrosis in heavy alcohol drinkers. These biomarkers could be useful to rapidly evaluate liver injuries and the efficacy of therapies.

Abstract
AIM To study the effect of the drug metadoxin on drug-metabolizing liver function in patients with liver lesions alcoholic etiology (ALD). MATERIALS AND METHODS 36 patients with ALD, of which 16 patients were diagnosed with hepatitis, while 20 - with the liver cirrhosis. All the patients underwent biochemical blood analysis and the study of drug-metabolizing liver function according to the pharmacokinetics of antipyrine in saliva before and after treatment with metadoxin. Metadoxin was administered at a dose of 500 mg once a day for 28 days. Concentrations of antipyrine in saliva samples were determined by HPLC. RESULTS. It was shown that of 36 patients examined in the 28-patients with ALD (group 2) there was a significant decrease in activity of liver enzymes according to the test with antipyrine (T1/2 = 28.7 +/- 3.4, CL = 17,9 +/- 5.2; p < 0,01 vs normal), whereas in 8 patients (group 1) was noted the typical for alcohol inductive influence on the activity of liver monooxygenases (T1/2 = 7.8 +/- 1.5, CL = 39.1 +/- 6.8; p < 0,05 vs normal). As a result of the 28-day therapy with metadoxin was a normalization of the pharmacokinetic parameters of AP in Gr. 1 (12.6 +/- 1.8; p < 0.05; NS vs normal) and a significant improvement of it in patients of Gr. 2 (17.9 +/- 5.2, vs N, p <0.05). Biochemical markers of ALD (AST/ALT, GGT, ALP) also demonstrated a positive dynamics in patients of both study groups. Correlation analysis of changes in CL and GGT (r1) and changes in AST/ALT and T1/2 (r2) showed a fairly high degree of correlation between these parameters (r1 = 0.58, r2 = 0.65). CONCLUSION The results showed marked improvement of drug-metabolizing liver function according to the test with antipyrine in patients with ALD after treatment with metadoxin.

Abstract
CONTEXT Ethnobotanical surveys conducted on Pelargonium reniforme Curtis (Geraniaceae) have shown that the aqueous root extracts are used to treat alcohol-induced liver damage. OBJECTIVE We evaluated the antioxidant properties of the extract and its effects on alcohol-induced hepatotoxicity using Wistar rats. MATERIALS AND METHODS Alcohol-induced hepatotoxicity studies were carried out by observing the effect of the aqueous root extract on some liver marker enzymes, bilirubin, and total protein after liver damage. The levels of some phenolic compounds were determined by standard methods. Also, the reducing power of the plant extract and its ability to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH*) and 2,2'-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS*+) radicals were determined to evaluate its antioxidant activity. RESULTS AND DISCUSSION The results obtained show that the plant extract possessed significant antioxidant activity. It had a significant level of phenolic compounds, scavenged DPPH* and ABTS*+ radicals effectively, and demonstrated good reducing power. This may indicate that the plant contained compounds which can remove toxic metabolites following alcohol abuse. Serum analysis of animals treated with only ethanol showed a significant increase in the levels of liver marker enzymes and total and unconjugated bilirubin, while a significant decrease was observed in the levels of conjugated bilirubin and total proteins. Administration of the plant extract restored the levels of these markers to normal levels, and this indicates the ability of the plant extract to restore normal functioning of a damaged liver. CONCLUSION The study shows that P. reniforme is a potential source of antioxidants and compounds which are useful in treating alcoholic liver damage.

Abstract
The protective effects of Semen Hoveniae extract (SHE) from Hovenia dulcis Thunb. (Rhamnaceae) on acute alcohol-induced liver injury were investigated in vivo using mice as test models. In the present study, SHE (150, 300, 600 mg/kg/day) was given to mice by intragastric administration for 4 days. Mice were gavaged with 60% ethanol 10 mL/kg after the last dose of extract. Six hours after alcohol administration, liver injury was evaluated by biochemical examination. Lipid peroxidation and the activity of antioxidants were measured by spectrophotometric methods. In mice, administration of SHE significantly decreased the activities of alanine aminotransferase (ALT) and aspartate transaminase (AST) in serum. Administration of SHE also protected against alcohol-induced alcohol dehydrogenase (ADH) elevation in mice. Concurrently, there was an augmentation in the activities of antioxidant enzymes such as superoxide dismutase (SOD), glutathione S-transferase (GST), and glutathione (GSH), and it also facilitated alcohol metabolism. Acute toxicity tests showed that a single dose of oral SHE up to 22 g/kg did not result in any death or toxic side effects in mice during 14 days' observation. These results demonstrate that SHE could protect against acute alcohol-induced liver injury without any toxic side effects. Therefore, Semen Hoveniae has potential for the development of a clinically useful agent which could protect the liver from alcohol-induced injury.
