Liver fibrosis is a chronic liver injury caused by various etiologies and a complex pathological change with the activation of hepatic stellate cells as the central link, and various signaling pathways are involved in the regulation of such complex lesions. It has the dual nature of repair and damage and may eventually progress to liver cirrhosis, liver failure, and even liver cancer. In recent years, rapid progress has been made in the basic research on the cell signal transduction pathways associated with liver fibrosis, and some achievements have been made in the research on the treatment strategy of liver fibrosis. This article briefly reviews the cell signaling pathways associated with the development of liver fibrosis, including the JAK/STAT signaling pathway, the NF-κB signaling pathway, the MAPK signaling pathway, the TGF-signaling 1/Smad signaling pathway, the Wnt signaling pathway, the Hedgehog signaling pathway, and the Notch signaling pathway, and also introduces the potential therapeutic strategies for liver fibrosis at present.

Objective To explore the influence factors on hepatitis B virus (HBV) relapse after nucleos(t)ide analogues (NA) withdrawal in the chronic hepatitis B (CHB) patients who met NA cessation criteria. Methods Eighty-one consecutive CHB patients were treated with NA, 38 with lamivudine (LAM), 25 with adefovir dipivoxil (ADV), 12 with entecavir (ETV), 6 with LAM +ADV. Among recruited patients, 40 were hepatitis B virus e antigen (HBeAg) positive, 41 were HBeAg negative, 67 of them were initial treatment, 14 were retreatment due to resistance to NA at baseline. The treatment was discontinued after meeting China therapeutic end-point criteria. HBV DNA, HBV serological markers, alanine aminotransferase (ALT) were measured respectively at baseline, every month before virological response, every 3 months after virological response, every month within first 6 months and every 2 months over 6 months after drugs withdrawal. Twelve probable influence factors on relapse which were sex, age, HBV family history, baseline HBV DNA,baseline HBeAg status, baseline ALT, virological response time, total duration of treatment, duration of additional treatment, the level of hepatitis B virus surface antigen (HBsAg) at cessation therapy,initial treatment or retreatment, drug category were analyzed with univariate, multivariate Cox regression modle and stratified analysis. The cumulative relapse was calculated by the Kaplan-Meier method. Results A total of 36 patients (44. 4%) relapsed within 1 year. Initial treatment or retreatment, HBV family history, virological response time, the level of HBsAg at cessation therapy were independent risk factors. The relapse rate of retreatment was higher than that of initial treatment (78.6% vs 37. 3% , χ2 = 7. 983, P = 0. 005) , those of patients with HBV family history higher than without family history (64. 5% vs 15.0%, χ2 =12. 096,P = 0.002), those of patients obtained virological response within 3 months lower than after 3 months(34. 0% vs 64. 3% , χ2 =6. 823,P=0. 009) , those of patients with HBsAg≤150 μg/L at cessation therapy lower than >150 μg/L(27. 6% vs 53. 8%, χ2=5. 199,P=0. 023). Conclusions Retreatment, HBV family history, later virological response and higher HBsAg level at cessation therapy are risk factors of relapse after NA withdrawal. Such patients should be treated with prolonged duration after meeting end-point criteria to strengthen the efficacy.

Objective To evaluate the clinical efficacy and safety of ritonavir-boosted danoprevir (DNVr) combined with daclatasvir (DCV) in the treatment of patients with genotype 1b chronic hepatitis C (CHC).Methods Thirty-three patients with genotype 1b CHC admitted in the Department of Infectious Diseases of the First Affiliated Hospital of Nanchang University from August 2018 to February 2019 were enrolled.All the patients received DNVr +DCV antiviral treatment.HCV RNA levels were detected before and 2, 4, 12 weeks after treatment, and after drug withdrawal , respectively.Indicators of liver and kidney function and adverse events were observed.ANOVAV of repeated measurement was used to analyze the data. Results The baseline viral loads of 33 patients ranged from 1.12×104 to 1.76×107 IU／mL.Two weeks after treatment the viral loads of all patients were down to the lowest limit of detection (＜500 IU／mL). Serum ALT, AST and TBil levels returned to norml ( F＝58.26, 14.49 and 20.16, all P＜0.05) and sustained virologic response reached 100%12 weeks after drug withdrawal.Three cases had minor adverse reactions during the treatment.Conclusion DNVr combined with DCV can achieve a rapid and strong virological response in the treatment of patients with genotype 1b CHC with good safety.

Objective: To explore the efficacy of glucocorticoid (GC) therapy on hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF), and the effectiveness and safety of voriconazole (VCZ) in preventing pulmonary Aspergillus infection in HBV-ACLF patients treated with GC. Methods: Two hundred and thirty-two patients with HBV-ACLF were enrolled from January 2016 to December 2018 in the First Affiliated Hospital of Nanchang University. They were divided into non-GC group (104 cases), GC group (74 cases), and GC+ VCZ group (54 cases). The observation period was four months. The baseline liver function, the incidence of pulmonary Aspergillus infection, the survival rate during observation period, and the incidence of complications were compared among the three groups. The adverse reactions of VCZ were observed to identify the best dose for prevention. Quantitative data were analyzed by analysis of variance or rank sum test. Count data were analyzed by chi-square test or Fisher exact test. Results: The baseline liver functions were not significantly different among the three groups (all P>0.05). The incidence of pulmonary Aspergillus infection in the GC group (22.97%(17/74)) was both higher than that in the non-GC group (5.77%(6/104)) and GC+ VCZ group (1.85%(1/54)), the differences were both statistically signifrcant (χ²=11.373 and 9.843, respectively, both P<0.01). The overall mortality rate of HBV-ACLF patients with pulmonary Aspergillus infection was 79.2%(19/24). The survival rate in non-GC group (37.5%(39/104)) showed no statistical difference with that in GC group (39.19%(29/74), χ²=0.052, P=0.819). The survival rate of GC+ VCZ group (66.67%(36/54)) was significantly higher than that in GC group and non-GC group (χ² =12.126 and 9.431, respectively, both P<0.01). The blood concentrations of VCZ were randomly measured in 16 patients from the GC+ VCZ group, and the range was 0.82-5.38 mg/L, with no evident adverse reactions. Conclusions The GC treatment is effective in HBV-ACLF patients in early stage. The VCZ treatment effectively reduces the incidence of pulmonary Aspergillus infection in HBV-ACLF patients receiving GC treatment and increases the survival rate. Oral VCZ (200 mg/d) treatment has a stable blood concentration in HBV-ACLF patients, with rare adverse reactions and good safety.

Objective To investigate the influencing factors for low-level viremia (LLV) and their dynamic changes in chronic hepatitis B (CHB) patients treated with nucleos(t)ide analogues (NAs) for the first time. Methods A retrospective analysis was performed for 78 CHB patients who attended Department of Infectious Diseases, The First Affiliated Hospital of Nanchang University, from November 2020 to March 2022 and received antiviral therapy with NAs for at least 12 months, and according to HBV DNA level during treatment, they were divided into sustained virologic response (SVR) group with 58 patients and LLV group with 20 patients. The independent samples t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. The multivariate Logistic regression analysis was used to investigate the independent influencing factors for LLV and establish a predictive model, and the receiver operating characteristic (ROC) curve was used to evaluate the predictive value of this model. The Kaplan-Meier method was used to analyze cumulative HBV DNA negative conversion rate, and the Log-rank test was used for comparison. The analysis of variance with repeated measures was used to analyze the differences in HBV DNA and HBsAg between the two groups or within each group at weeks 0, 12, 24, 36, and 48. Results Compare with the SVR group, the LLV group had significantly higher HBeAg positive rate (90.0% vs 48.3%, χ 2 =10.701, P =0.001), log(HBV DNA) value (7.26±1.46 vs 5.65±1.70, t =-4.178, P < 0.001), and log(HBsAg) value (4.53±0.86 vs 3.44±0.93, t =-4.813, P < 0.001) and significantly lower age [29 (26-34) vs 33 (30-43), Z =-2.751, P =0.009], alanine aminotransferase (ALT) [67.0 (54.0-122.0)U/L vs 111.0 (47.0-406.0)U/L, Z =-2.203, P =0.028], aspartate aminotransferase [43.5 (32.8-62.8) U/L vs 77.5 (35.0-213.0)U/L, Z =-2.466, P =0.014], and liver stiffness measurement [7.7 (6.3-8.5)kPa vs 8.9 (7.2-11.4)kPa, Z =-2.022, P =0.043]. The multivariate logistic regression analysis showed that baseline HBV DNA (odds ratio [ OR ]=2.365, 95% confidence interval [ CI ]: 1.220-4.587, P =0.011), HBsAg ( OR =4.229, 95% CI : 1.098-16.287, P =0.036), and ALT ( OR =0.965, 95% CI : 0.937-0.994, P =0.018) were independent influencing factors for LLV in CHB patients, and the predictive model of Logit(MLLV)=-8.668+1.441×lgHBsAg+0.598×lgHBV DNA-0.016×ALT was established based on these factors, which had a larger area under the ROC curve than HBV DNA, HBsAg, and ALT (0.931 vs 0.774/0.856/0.666), with a sensitivity of 85.00% and a specificity of 93.10% at the optimal cut-off value of 0.44. The CHB patients with baseline HBV DNA > 7.29 lgIU/mL or HBsAg > 4.38 lgIU/mL had a significantly lower DNA negative conversion rate than those with DNA ≤7.29 lgIU/mL or HBsAg ≤4.38 lgIU/mL ( χ 2 =22.52 and 26.35, both P < 0.001). In the CHB patients, the highest reduction rates of HBV DNA and HBsAg were observed at weeks 12 and 24, respectively, and the LLV group had significantly higher levels of HBV DNA and HBsAg than the SVR group at weeks 0, 12, 24, 36, and 48 (HBV DNA: t =-4.084, -4.526, -5.688, -7.123, and -6.266, all P < 0.001; HBsAg: t =-4.652, -4.691, -4.952, -4.804, and -4.407, all P < 0.001). Conclusion For the CHB patients treated with NAs for the first time, those with high HBV DNA load, high HBsAg quantification, and low ALT level at baseline are more likely to develop LLV, and dynamic monitoring of these indices is of great significance to observe the onset of LLV.
