Objective:To investigate the effect of paeoniflorin on toll-like receptor 4(TLR4)/nuclear transcription factor(NF-κB) signaling pathway of streptozotocin combined with ovariectomized mice, and to explore whether it can improve the cognitive impairment of ovariectomized diabetic mice.Methods:Ninety female C57BL/6J mice were divided into SHAM group, ovariectomy group, diabetes group(intraperitoneal injection of STZ 50 mg·kg -1·d -1 for 5 consecutive days), dual model group(DM modeling and OVX operation), paeoniflorin low-dose intervention group(OVX+ STZ+ L-PF 50 mg·kg -1·d -1), paeoniflorin high-dose intervention group(OVX+ STZ+ H-PF 100 mg·kg -1·d -1; all groups n=15). After 8 weeks of paeoniflorin intervention, their cognitive function was tested by behavioral experiments(Morris water maze and Y maze). The pathological changes of hippocampal tissue were observed by HE and Nissl staining. The mRNA expressions of TLR4, tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β) and interleukin-6(IL-6) in hippocampal tissues were detected by real-time fluorescence quantitative PCR. The expression of TLR4, NF-κB P65, TNF-α, IL-6, IL-1β, β-amyloid protein(Aβ), tau proteins, and p-tau proteins were detected by Western blot. Results:Compared with SHAM group, the learning and memory ability of ovariectomy group, diabetes group and dual model group decreased, hippocampal cells were damaged, and the expression of related gene mRNA and protein were increased, especially in dual model group; Compared with dual model group, paeoniflorin intervention could delayed the learning and memory impairment, improve cognitive function, reduce the degree of hippocampal injury, and decrease the expression levels of related gene mRNA and protein, The above changes were the most pronounced at paeoniflorin high-dose intervention group.Conclusion:Paeoniflorin improves cognitive dysfunction in ovariectomized diabetic mice by inhibiting TLR4/NF-κB signaling pathway.

Objective:To comparatively study the similarities and differences between the clinical, pathological, and risk factors of advanced fibrosis in men and women with non-alcoholic fatty liver disease (NAFLD).Methods:267 patients with NAFLD diagnosed by liver biopsy were retrospectively included, and were divided into male and female groups. The difference of clinical and pathological indexes were compared between the two groups. The measurement data were in accordance with normal distribution. The comparison between the two groups was performed by independent sample t-test. The non-parametric test was used for non-normal distribution. The classification data were expressed as a percentage, and the chi-square test was used for comparison between groups. Logistic regression analysis was used to analyze the risk factors.Results:The age of onset of NAFLD was significantly lower in male than female patients ( P < 0.01). There was no statistically significant difference between the male and female groups in terms of body mass index and the prevalence of type 2 diabetes ( P > 0.05). Biochemical index: The levels of alanine aminotransferase, albumin, total bilirubin and uric acid were significantly higher in male than female patients ( P < 0.01). Liver pathology: The proportion of ballooning degeneration was significantly lower in male than female patients ( P < 0.01). There was not statistically significant difference between the two groups in the proportion of steatohepatitis score, non-alcoholic steatohepatitis (52.0% vs. 61.5%, P = 0.283) and advanced liver fibrosis (14.3% vs. 17.8%, P = 0.162). Thrombocytopenia was a common independent risk factor for advanced stage liver fibrosis ( OR = 0.984, 0.978~0.989, P < 0.01). Type 2 diabetes was only an independent risk factor for advanced stage liver fibrosis in men ( OR = 6.557, 1.667~25.782), P < 0.01). Elevated AST was only an independent risk factor for advanced stage liver fibrosis in women ( OR = 1.016, 1.003~1.028, P = 0.012). Conclusion:In NAFLD patients, there are some clinical and pathological differences between genders. Platelets are a common predictor of advanced liver fibrosis in men and women. Type 2 diabetes in men and elevated aspartate aminotransferase in women can be regarded as independent risk factors for advanced liver fibrosis.

Objective:This study aims to compare the antiviral treatment similarities and differences in the population covered by the 2024 version of the World Health Organization's (WHO) hepatitis B prevention and treatment guidelines and the current Chinese hepatitis B prevention and treatment guidelines, so as to explore their impact on the indications for antiviral therapy in Chinese patients with chronic hepatitis B (CHB).Methods:The information of patients with chronic hepatitis B virus infection who did not receive antiviral treatment was collected through the registration database of the China Clinical Research Platform for Hepatitis B Elimination. Descriptive statistics were conducted on the demographic, blood, biochemical, and virological levels of patients according to the treatment recommendations of the two versions of the guidelines. The Mann-Whitney U test and χ2 test were used to compare the differences and proportional distribution of the treatment populations covered by the two guidelines. The χ2 test was used to analyze the coverage rate of different antiviral treatment indications.Results:A total of 21,134 CHB patients without antiviral treatment were enrolled. 69.4% of patients met the 2024 versions of the WHO guidelines' recommendations. 85.0% of patients met the current Chinese hepatitis B prevention and treatment guidelines. The WHO guidelines for antiviral therapy indications were met in younger patients with higher levels of ALT, AST, and APRI scores, as well as greater proportion of patients with higher viral loads (P<0.001). The WHO guidelines recommended a cut-off value of APRI>0.5, which raised the proportion of patients on antiviral therapy from 6.6% to 30.9%. 45.7% of patients met the antiviral indications for HBV DNA >2000 IU/ml with abnormal transaminase (ALT>30 U/L for males and ALT>19 U/L for females). The reduced APRI diagnostic cut-off value and ALT treatment threshold had further increased the treatment coverage rate by 91.6% in patients with chronic HBV infection in line with the 2024 versions of WHO guidelines.Conclusion:The reduction of the APRI diagnostic cut-off value and the ALT treatment threshold, based on the current hepatitis B guidelines of China, will further improve the treatment coverage of CHB patients.

Background/Aims:
Existing hepatocellular carcinoma (HCC) prediction models are derived mainly from pretreatment or early on-treatment parameters. We reassessed the dynamic changes in the performance of 17 HCC models in patients with chronic hepatitis B (CHB) during long-term antiviral therapy (AVT).
Methods:
Among 987 CHB patients administered long-term entecavir therapy, 660 patients had 8 years of follow-up data. Model scores were calculated using on-treatment values at 2.5, 3, 3.5, 4, 4.5, and 5 years of AVT to predict threeyear HCC occurrence. Model performance was assessed with the area under the receiver operating curve (AUROC). The original model cutoffs to distinguish different levels of HCC risk were evaluated by the log-rank test.
Results:
The AUROCs of the 17 HCC models varied from 0.51 to 0.78 when using on-treatment scores from years 2.5 to 5. Models with a cirrhosis variable showed numerically higher AUROCs (pooled at 0.65–0.73 for treated, untreated, or mixed treatment models) than models without (treated or mixed models: 0.61–0.68; untreated models: 0.51–0.59). Stratification into low, intermediate, and high-risk levels using the original cutoff values could no longer reflect the true HCC incidence using scores after 3.5 years of AVT for models without cirrhosis and after 4 years of AVT for models with cirrhosis.
Conclusions
The performance of existing HCC prediction models, especially models without the cirrhosis variable, decreased in CHB patients on long-term AVT. The optimization of existing models or the development of novel models for better HCC prediction during long-term AVT is warranted.

Objective:Our study aims to determine histological regression and clinical improvement after long-term antiviral therapy in hepatitis B virus-related cirrhosis patients.Methods:Treatment-na?ve chronic hepatitis B patients with histologically or clinically diagnosed liver cirrhosis were enrolled. Liver biopsies were performed after 5 years entecavir-based antiviral treatment. Patients were followed up every 6 months. Cirrhosis regression was evaluated based on Metavir system and P-I-R score. Clinical improvement was evaluated before and after the long-term treatment. Kruskal Wallis test and Wilcoxon signed-rank test were used for continuous variables, Fisher's exact test was used for categorical variables and multivariate analysis was performed using logistic regression analysis.Results:Totals of 73 patients with HBV-related liver cirrhosis were enrolled. Among them, 30 (41.1%) patients were biopsy proved liver cirrhosis and the remaining 43 (58.9%) cirrhotic patients were diagnosed by clinical features. Based on Metavir system and P-I-R score, 72.6% (53/73) patients attained histological regression. Furthermore, 30.1% (22/73) were defined as significant regression (Metavir decrease ≥2 stage), 42.5% (31/73) were mild regression (Metavir decrease 1 stage or predominantly regressive by P-I-R system if still cirrhosis after treatment) and 27.4% (20/73) were the non-regression. Compared to levels of clinical characteristics at baseline, HBV DNA, ALT, AST, liver stiffness(decreased from 12.7 to 6.4 kPa in significant regression, from 18.1 to 7.3 kPa in mild regression and from 21.4 to 11.2 kPa in non-regression)and Ishak-HAI score significantly decreased after 5 years of anti-HBV treatment, while serum levels of platelets and albumin improved remarkably ( P<0.05). In multivariate analysis, only the pre-treatment liver stiffness level was associated with significant regression ( OR=0.887, 95% CI: 0.802-0.981, P=0.020). Conclusions:After long-term antiviral therapy, patients with HBV-related cirrhosis are easily to attain improvements in clinical parameters, while a certain percentage of these patients still cannot achieve histological reversal.

Objective:
To investigate the methods for qualitative pathological assessment of dynamic changes in liver fibrosis/cirrhosis after antiviral therapy in patients with chronic hepatitis B (CHB), since antiviral therapy can partially reverse liver fibrosis and cirrhosis caused by hepatitis B and semi-quantitative, rather than qualitative, pathological assessment is often used for the research on liver fibrosis regression.
Methods:
Previously untreated CHB patients with liver fibrosis and cirrhosis were enrolled, and liver biopsy was performed before treatment and at 78 weeks after the antiviral therapy based on entecavir. The follow-up assessment was performed once every half a year. Based on the proportion of different types of fibrous septum, we put forward the new qualitative criteria called P-I-R classification (predominantly progressive, predominantly regressive, and indeterminate) for evaluating dynamic changes in liver fibrosis. This classification or Ishak fibrosis stage was used to evaluate the change in liver fibrosis after treatment and Ishak liver inflammation score was used to evaluate the change in liver inflammation after treatment.
Results:
A total of 112 CHB patients who underwent liver biopsy before and after treatment were enrolled, and among these patients, 71 with an Ishak stage of ≥3 and qualified results of live biopsy were included in the final analysis. Based on the P-I-R classification, 58% (41/71) were classified as predominantly progressive, 29% (21/71) were classified as indeterminate, and 13% (9/71) were classified as predominantly regressive; there were no significant differences between the three groups in alanine aminotransferase, aspartate aminotransferase, albumin, HBeAg positive rate, HBV DNA, and liver stiffness (
