  • Objectives : This study investigated the liver-protective effects of MJY2018, a Herbal formula, against alcoholic fatty liver disease and anti-oxidative effects. Methods : Its effects were investigated in an alcoholic fatty liver disease model in male C57BL/6 mice, which were fed Lieber-DeCarli liquid diet containing ethanol. MJY2018 (100 and 200 mg/kg bw/day) or silymarin (50 mg/kg bw/day) were orally administered daily in the alcoholic fatty liver disease mice for 16 days. Results : The results indicate that MJY2018 promotes hepatoprotection by significantly reducing aspartate transaminase (AST) and alanine transaminase (ALT) levels as indicators of liver damage in the serum. Furthermore, MJY2018 reduced accumulation of triglyceride and total cholesterol, increased levels of superoxide dismutase (SOD) and glutathione (GSH) in the livers of the alcoholic fatty liver disease mice model. Additionally, it improved the serum alcohol dehydrogenase (ADH) activity. Conclusions : These results indicate that MJY2018 were effective in improving and protecting oxidative stress and alcoholic liver disease.

  • Chronic liver disease progresses through several stages, fatty liver, steatohepatitis, cirrhosis, and eventually, it leads to hepatocellular carcinoma (HCC) over a long period of time. Since a large proportion of patients with HCC are accompanied by cirrhosis, it is considered to be an important factor in the diagnosis of liver cancer. This is because cirrhosis leads to an irreversible harmful effect, but the early stages of chronic liver disease could be reversed to a healthy state. Therefore, the discovery of biomarkers that could identify the early stages of chronic liver disease is important to prevent serious liver damage. Biomarker discovery at liver cancer and cirrhosis has enhanced the development of sequencing technology. Next generation sequencing (NGS) is one of the representative technical innovations in the biological field in the recent decades and it is the most important thing to design for research on what type of sequencing methods are suitable and how to handle the analysis steps for data integration. In this review, we comprehensively summarized NGS techniques for identifying genome, transcriptome, DNA methylome and 3D/4D chromatin structure, and introduced framework of processing data set and integrating multi-omics data for uncovering biomarkers.

  • Recently, the incidence of metabolic dysfunction-associated steatotic liver disease (MASLD) is increasing due to the high prevalence of metabolic conditions, such as obesity and type 2 diabetes mellitus. Steatotic liver is a hotspot for cancer metastasis in MASLD. Altered lipid metabolism, a hallmark of MASLD, remodels the tissue microenvironment, making it conducive to the growth of metastatic liver cancer. Tumors exacerbate the dysregulation of hepatic metabolism by releasing extracellular vesicles and particles into the liver. Altered lipid metabolism influences the proliferation, differentiation, and functions of immune cells, contributing to the formation of an immunosuppressive and metastasis-prone liver microenvironment in MASLD. This review discusses the mechanisms by which the steatotic liver promotes liver metastasis progression, focusing on its role in fostering an immunosuppressive microenvironment in MASLD. Furthermore, this review highlights lipid metabolism manipulation strategies for the therapeutic management of metastatic liver cancer.

  • Ferroptosis is a type of regulated cell death recently discovered, characterized by the accumulation of iron-dependent lipid peroxides in the cell membrane, and it involves a complex network of signaling pathways, including iron metabolism, lipid peroxidation, and redox regulation. The dysregulation of these pathways can lead to the induction of ferroptosis and the development of liver diseases, such as alcoholic liver disease, non-alcoholic fatty liver disease, viral hepatitis, and liver cancer. Studies have demonstrated that targeting key molecules involved in iron metabolism, lipid peroxidation, and redox regulation can reduce liver injury and improve liver function in different liver diseases by inhibiting ferroptosis. Thus, modulation of ferroptosis presents a promising therapeutic target for treating liver diseases. However, further research is required to gain a more comprehensive understanding of the mechanisms underlying the role of ferroptosis in liver diseases and to develop more effective and targeted treatments.

  • Objectives : This study was done to evaluate the effect of stopping drinking, using alcoholic liver disease questionnaire, Diagnosis System of Oriental Medicine (DSOM) and Health Related Quality of Life (HRQOL). Methods : 49 men who satisfied the requirement participated in this trial. They stopped drinking for 6 weeks. They were analyzed using DSOM, alcoholic liver disease questionnaire and SF-36. The data were classified by age (<47,$\geq$48) and alcoholic intake per day (<100g,$\geq$100g). For HRQOL, the SF-36v2 Health Survey was used and Quality Metric Health Outcomes Scoring Software 2.0 (QualityMetric, Lincoln, RI, USA) was applied for the analysis. Results : The alcoholic liver disease questionnaire had a partial correlation with DSOM. Generally stopping drinking decreased Heat (熱). Especially in the group drinking over 100g per day, the correlation was high. In the group over 48 years old, spleen (脾) was improved comparatively. In the group with low HRQOL (PCS<31.43, MCS<23.33) deficiency (虛) was improved. Conclusions : We found that stopping drinking can improve pathogenic factors of alcoholic liver disease and the alcoholic liver disease questionnaire be a useful diagnostic method on alcoholic liver disease by comparison with DSOM.

  • Purpose: Non-alcoholic fatty liver disease (NAFLD) ranges in severity from simple steatosis to steatohepatitis. Early detection of NAFLD is important for preventing the disease from progressing to become an irreversible end-stage liver disease. We developed a nomogram that allows for non-invasive screening for NAFLD in obese children. Methods: Anthropometric and laboratory data of 180 patients from our pediatric obesity clinic were collected. Diagnoses of NAFLD were based on abdominal ultrasonographic findings. The nomogram was constructed using predictors from a multivariate analysis of NAFLD risk factors. Results: The subjects were divided into non-NAFLD (n=67) and NAFLD groups (n=113). Factors, including sex, body mass index, abdominal circumference, blood pressure, insulin resistance, and levels of aspartate aminotransferase, alanine aminotransferase (ALT), γ-glutamyl transpeptidase (γGT), uric acid, triglycerides, and insulin, were significantly different between the two groups (all p<0.05) as determined using homeostatis model assessment of insulin resistance (HOMA-IR). In our multivariate logistic regression analysis, elevated serum ALT, γGT, and triglyceride levels were significantly related to NAFLD development. The nomogram was established using γGT, uric acid, triglycerides, HOMA-IR, and ALT as predictors of NAFLD probability. Conclusion: The newly developed nomogram may help predict NAFLD risk in obese children. The nomogram may also allow for early NAFLD diagnosis without the need for invasive liver biopsy or expensive liver imaging, and may also allow clinicians to intervene early to prevent the progression of NAFLD to become a more advanced liver disease.

  • Cirrhosis is a consequence of chronic liver disease characterized by replacement of liver tissue by fibrosis, scar tissue and regenerative nodules leading to loss of liver function. Liver Cirrhosis is most commonly caused by alcoholism, hepatitis B and C, and fatty liver disease, but has many other possible causes. Some cases are idiopathic disease from unknown cause. Abdomen of liver Computed tomography(CT) is one of the primary imaging procedures for evaluating liver disease such as liver cirrhosis, Alcoholic liver disease(ALD), cancer, and interval changes because it is economical and easy to use. The purpose of this study is to detect technique for computer-aided diagnosis(CAD) to identify liver cirrhosis in abdomen CT. We experimented on the principal components analysis(PCA) algorithm in the other method and suggested texture information analysis(TIA). Forty clinical cases involving a total of 634 CT sectional images were used in this study. Liver cirrhosis was detected by PCA method(detection rate of 35%), and by TIA methods(detection rate of 100%-AGI, TM, MU, EN). Our present results show that our method can be regarded as a technique for CAD systems to detect liver cirrhosis in CT liver images.

  • The purpose of this study is to evaluate the nutritional status of vitamin and minerals in the patients with alcoholic liver disease and to obtain the materials for nutritional education for alcoholics. The subjects consist of 80 patients with alcoholic liver cirrhosis(ALC) and 12 patients with alcoholic fatty liver(AFL). The control group included 57 alcoholics without liver disease(A), 32 patients with viral liver cirrhosis(VLC) and 194 normal men(NL). Biochemical evaluation of nutritional status was investigated by the analysis of blood samples. The frequency of vitamin B1 deficiency in the ALC, AFL and A groups as indicated by the erythrocyte transketolase activity coefficient were 46.0%, 66.7% and 57.9% respectively. The frequency of vitamin B2 deficiency in the ALC, AFL and A groups as indicated by the erythrocyte glutathione reductase activity coefficient were 9.8%, 8.3% and 38.6% respectively. Vitamin A deficiency was not detected in the alcoholic subjects. The frequency of vi tamin E deficiency in ALC, AFL and A were 96.3%, 66.7% and 86.0% respectively. The levels of plasma lipid peroxidation products were significantly higher in the alcoholic subjects than in the normal subjects. The frequency of subjects below normal range of hemoglobin were 85.0% in ALC, 50.0% in AFL and 31.6% in A. The frequency of copper deficiency in the ALC, AFL and A groups were 48.4%, 16.7% and 17.5% respectively. The frequency of zinc deficiency in the ALC, AFL and A groups were 83.8%, 41.7% and 66.7% respectively. Overall, the vitamin and minerals status of the alcoholic subjects in this study was evaluated to be very poor on the basis of biochemical assessments. The results suggest that alcohol abuse and poor dietary intake could cause malnutrition and may be important risk factors in causing alcoholic liver disease in alcoholics. In addition, vitamin B1, vitamin B2, Cu, Fe and antioxidant supplementation may be effective in nutritional therapy for chronic alcoholics.

  • Interferon-${\gamma}$-inducible protein 10 (IP-10), also known as chemokine C-X-C motif ligand (CXCL) 10, is closely associated with antiviral immunity and the progression of chronic hepatitis B (CHB). However, the value of baseline serological and histological IP-10 expression levels in predicting the efficacy of the antiviral response to nucleoside/nucleotide analogues (NAs) is still unknown. In our research, intrahepatic and peripheral IP-10 expression levels were systemically examined before and after treatment with entecavir (ETV). Baseline serological and histological IP-10 expression levels were significantly increased in patients with CHB, particularly in patients with higher degrees of liver inflammation and liver fibrosis. Moreover, higher baseline intrahepatic IP-10 levels indicated better prognoses in patients with CHB after entecavir therapy. The baseline IP-10 level was also positively associated with several clinical parameters, including baseline levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), hepatitis B virus (HBV) DNA, and hepatitis B surface antigen (HBsAg), and with the decrease in HBsAg levels after treatment. In addition, monocyte-derived IP-10 was expressed at higher levels in patients with CHB than in patients with liver cirrhosis (LC) and healthy controls (HC). According to the results of our in vitro experiments, IP-10 directly promoted hepatocyte apoptosis. Based on these findings, baseline serological and histological IP-10 levels might predict CHB severity and the decrease in HBsAg levels after entecavir therapy.

  • Purpose: The purpose of the study was to examine the related factors of quality of life (QOL) among middle-male with chronic liver disease. Method: The participants in this study were 110 patients with chronic liver disease who were recruited from the outpatient clinic of hospital. Between March and May 2014, data were collected through questionnaires and medical record review. Data analysis was performed using PASW (SPSS) 19.0 program, and one-way ANOVA, Pearson correlation coefficients, and enter multiple regression analysis. Results: The mean QOL of this study was 48.16/100. The significant correlates of QOL were anxiety-depression (${\beta}$=.33, p<.001), symptom experience (${\beta}$=.15, p=.001), health perception(${\beta}$=.31, p<.001), disease status(${\beta}$=.17, p=.022), spouse (${\beta}$=.23, p=.001), and these variables explained 68.6% of variance in QOL. Conclusion: The study suggests that psychological aspects are an important factor in explaining QOL of the middle-male with chronic liver disease. Screening and minimizing anxiety-depression could be effective strategies in enhancing QOL of middle-male with chronic liver disease.
