OBJECTIVETo establish a zebrafish model of liver fibrosis via diethylnitrosamine (DEN)-induced liver injury.
METHODSA total of 120 wild-type 3-month-old zebrafish were randomly divided into DEN-treated group and control group. The survival rate and behavioral changes of each group were observed. After treatment with DEN for 2, 4, and 6 weeks, liver index was measured, and liver fibrosis was evaluated with HE staining, Gomori staining and Sirius red staining.
RESULTSNo obvious behavioral change was observed in DEN-treated group during the experiment. Compared with that in control group, the liver index of zebrafish in DEN-treated group showed no significantly changes at the time points of observation. Proliferation of reticulate fibers was found in 30% of zebrafish treated with DEN for 4 weeks, and the rate increased to 80% at 6 weeks when reticulate fibers and collagen fibers actively proliferated to result in fiber collapse and formation of fibrotic nodules.
CONCLUSIONA stable zebrafish liver fibrosis model was successfully established by inducing liver damage to facilitate studies of the pathogenesis of liver fibrosis and screening therapeutic drugs.

OBJECTIVETo establish a diet-induced obesity model in zebrafish larvae.
METHODSAt 7 days post-fertilization (dpf), 200 zebrafish larvae with normal development were randomly allocated to two groups with the feeding quantity of 30 mg per day (normal feeding group) or 180 mg per day (overfed group) for 20 days. The weight, length, BMI, triglyceride (TG) and total cholesterol (TCH) of each group were measured. Whole-mount Oil Red O staining, frozen Oil Red O staining and hematoxylin-eosin (HE) staining were used to estimate the rate of hepatic steatosis and liver histology of the zebrafish. The dynamic change of hepatic lipid droplets and distribution of adipose tissue were observed with Nile Red staining in overfed zebrafish in vivo.
RESULTSThe weight, length, BMI and TG of overfed zebrafish were significantly increased compared with those in normal feeding group. Whole-mount Oil Red O staining showed that the percent of hepatic steatosis in overfed group (89.4%) was markedly higher than that in normal feeding group (20.7%). Macrovesicular steatosis was observed in the liver of the overfed larvae. Nile Red staining visualized hepatic lipid droplets and the distribution of larval adipose tissue, which increased with feeding time in the overfed zebrafish. Starving larvae showed depletion of fat and hepatic lipid, and adipose tissue was induced after refeeding.
CONCLUSIONSWe successfully established an diet-induced obesity model in zebrafish larva, in which Nile Red staining allows in vivo observation of the adipocytes and hepatic lipid droplets.

ObjectiveTo investigate the preventive and therapeutic effects of Tiaogan Huaxian pills combined with entecavir on hepatic fibrosis in chronic hepatitis B with liver Qi stagnation, spleen deficiency, and blood stasis syndrome and its effect on diffusion-weighted imaging (DWI). MethodClinical data of 117 patients with liver disease who visited the Department of Hepatology at the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2021 to April 2022 were retrospectively analyzed. According to different treatment plans, they were divided into a control group (59 cases) and a treatment group (58 cases). Both groups of patients received entecavir-based etiology treatment, and the treatment group added Tiaogan Huaxian pills on the basis of basic treatment. Both groups were treated for 24 weeks. Before and after treatment, the two groups were compared in terms of alanine aminotransferase (ALT), advanced surgical technologies (AST), total bilirubin (TBil), hepatitis B virus (HBV)-DNA conversion rate, liver stiffness measurement (LSM), four items of liver fibrosis (hyaluronidase, type Ⅲ pro-collagen, type Ⅳ collagen, and laminin), the fibrosis index based on four factors (FIB-4), the aspartate aminotransferase to platelet ratio index (APRI), the apparent diffusion coefficient (ADC) value in magnetic resonance imaging (MRI), and traditional Chinese medicine symptom scores, so as to analyze the efficacy of the two groups. ResultBefore treatment, there was no significant difference in ALT, AST, TBil, LSM, four items of liver fibrosis, FIB-4, APRI, HBV-DNA conversion rate, ADC value, and traditional Chinese medicine symptom scores between the two groups. After treatment, both groups of patients showed significant reductions in ALT, AST, TBil, LSM, hyaluronidase, type Ⅲ pro-collagen, type Ⅳ collagen, laminin, FIB-4, and APRI (P<0.05) and a significant increase in ADC value (P<0.05) and HBV-DNA conversion rate (P<0.01). The traditional Chinese medicine symptom score of the treatment group decreased significantly (P<0.05). Compared with the control group after treatment, the effective rate of clinical traditional Chinese medicine in the treatment group was 91.38% (53/58), which was significantly higher than that of the control group (54.23%, 32/59) (Z=-4.325, P<0.01). In the treatment group, ALT, AST, TBil, LSM, hyaluronidase, type Ⅲ pro-collagen, type Ⅳ collagen, laminin, FIB-4, APRI, and traditional Chinese medicine symptom scores all decreased significantly (P<0.05), and the increase in ADC values was more significant (P<0.05), while the difference in HBV-DNA conversion rate was not statistically significant. There were no serious adverse reactions or events in either group. ConclusionTiaogan Huaxian pills combined with entecavir have significant clinical efficacy in the treatment of hepatic fibrosis in chronic hepatitis B, which can reduce liver inflammation activity, delay hepatic fibrosis progression, and reduce traditional Chinese medicine symptom scores. It is worthy of clinical promotion and application.

Objective:To explore the value of the aMAP risk score (age, male, albumin -bilirubin, and platelets) to predict early recurrence within one year after microwave ablation in patients with small hepatocellular carcinoma. Methods:This was a retrospective study that enrolled 142 patients diagnosed with hepatocellular carcinoma who were treated with microwave ablation in the Department of Hepatology Unit of Nanfang Hospital, Southern Medical University from July 2016 to July 2021. The cohort enrolled 121 male and 21 female patients, including 110 patients that were <60 years old. All the patients were followed-up after microwave ablation to evaluate residual tumor and recurrence of tumor by computed tomography or magnetic resonance imaging. The observation indices mainly included general data and imaging data of patients. Using the X-tile tools, patients were divided into two groups: a high aMAP score group and a low aMAP score group. Multivariate Cox regression analysis was conducted for comparison of independent risk factors.Results:Multivariate Cox regression showed that high aMAP score, maximum tumor diameter >20 mm, and high AFP were the independent risk factors of early recurrence (all P<0.05). Kaplan-Meier survival curves showed that the median recurrence-free survival was 25.5 months in the low aMAP score group and 6.1 months in the high aMAP score group ( P=0.001). Conclusions:The aMAP score could predict the early recurrence within 1 year of small hepatocellular carcinoma after microwave ablation. Patients with high aMAP score should undergo rigorous postoperative follow-up evaluations..

Objective To investigate the efficacy of continuous hepatic arterial infusion chemotherapy (HAIC) with the FOLFOX regimen and its multimodality therapeutic regimen in the treatment of patients with advanced hepatocellular carcinoma, as well as the influencing factors for prognosis. Methods A retrospective analysis was performed for the clinical data of 66 patients with advanced hepatocellular carcinoma who received continuous HAIC with FOLFOX regimen in Nanfang Hospital, Southern Medical University, from September 2018 to November 2021. The patients were observed in terms of objective response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), and median overall survival (mOS) after treatment, and treatment-related adverse reactions were recorded. For the patients with portal vein tumor thrombus, the effect of the treatment on portal vein tumor thrombus was assessed. The Kaplan-Meier method was used for survival analysis, and the Cox regression analysis was used to investigate the influencing factors for prognosis. Results According to the RECIST1.1 criteria, FOLFOX-HAIC and its multimodality therapeutic regimen achieved an ORR of 33.3% (22/66) and a DCR of 86.4% (57/66) in the treatment of 66 patients with advanced hepatocellular carcinoma, with an mPFS time of 8.2 months and an mOS time of 22.1 months. Among the 39 patients with portal vein tumor thrombus, 2 achieved complete remission, 8 achieved partial remission, 24 achieved stable disease, and 5 had disease progression, with an ORR of 25.6% (10/39) and a DCR of 87.2% (34/39). The main adverse reactions included gastrointestinal reactions (16.7%, 11/66), pyrexia (12.1%, 8/66), liver area pain (10.6%, 7/66), bone marrow suppression (3.0%, 2/66), and contrast agent allergy (3.0%, 2/66), and there were no grade > Ⅳ toxic or side effects or deaths caused by such complications. The Cox regression analysis showed that extrahepatic metastasis (hazard ratio [ HR ]=2.668, 95% confidence interval [ CI ]: 1.357-5.245, P < 0.05) and prothrombin time (PT) ( HR =1.282, 95% CI : 1.080-1.630, P < 0.05) were independent risk factors for PFS, and aspartate aminotransferase level ( HR =1.008, 95% CI : 1.002-1.013, P < 0.05) and PT ( HR =1.303, 95% CI : 1.046-1.630, P < 0.05) were independent risk factors for OS. Conclusion FOLFOX-HAIC and its multimodality therapeutic regimen has a certain clinical effect with controllable adverse reactions in the treatment of advanced hepatocellular carcinoma.
