As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

Background: The global rise in visual impairment, driven by population aging, the increasing prevalence of lifestyle-related chronic diseases, and environmental factors, has made it a critical public health concern, highlighting the urgent need for effective preventive strategies and eye health maintenance. Cuscutae Semen (CS), a traditional Chinese herbal medicine long regarded for its vision-enhancing properties, has been widely used to support ocular health. However, its underlying molecular mechanisms and bioactive constituents remain poorly understood, limiting its modernization and broader clinical application. Objective: This study aims to investigate the restorative effects of CS on visual impairment, elucidate its underlying mechanisms, and identify potential active components. Methods: A zebrafish model of visual impairment was established using mepanipyrim to simulate retinal structural damage and visual dysfunction. The therapeutic effects of CS were systematically evaluated through behavioral analyses and histomorphological observations. To elucidate the underlying mechanisms, an integrated approach was employed, combining transcriptome sequencing (RNA-seq), reverse transcription quantitative polymerase chain reaction validation, and immunofluorescence staining to identify critical genes and pathways involved. Furthermore, macroporous resin column chromatography was employed for the fractionation and screening of potential active components. Results: CS treatment significantly alleviated mepanipyrim-induced ocular abnormalities in zebrafish, restoring approximately 82% of the observed morphological defects. Behavioral assessments revealed that CS-treated zebrafish exhibited markedly increased swimming speed and distance, indicating enhanced visual light sensitivity. Histopathological analysis demonstrated that CS effectively repaired the structure of retinal cell layers. RNA-seq revealed that CS broadly reversed mepanipyrim-induced gene expression disturbances, suggesting a restorative effect on transcriptomic homeostasis. Gene Ontology enrichment analysis identified the phototransduction pathway as a key mediator of CS’s therapeutic effects. This was further supported by reverse transcription quantitative polymerase chain reaction validation of critical genes and immunofluorescence staining, which confirmed the restored expression of Pde6a and Gnat2, key proteins involved in photic signal transmission. Active component screening indicated that high-polar constituents, including chlorogenic acid, may constitute one of the major bioactive fractions responsible for the observed therapeutic effects. Conclusion: This study provides evidence of the vision-protective effects of CS in a zebrafish model, demonstrating that its therapeutic mechanism involves modulation of the phototransduction pathway. Chlorogenic acid was identified as one of the key bioactive constituents contributing to this effect. These findings not only provide scientific validation for the traditional use of CS in ocular protection but also present promising therapeutic prospects for the prevention and treatment of visual impairment.

Objective To construct a recombinant adenovirus vector expressing mouse SPINK5 gene,and observe its curative effect on the skin lesions in atopic dermatitis mice model. Methods By recombining DNA technology,the sequence of mouse SPINK5 gene was cloned into adeno?virus shuttle plasmid. Then it was transformed into HEK 293 cells with the adenoviral backbone plasmid to obtain the recombinant adenovirus. A mouse model of atopic dermatitis was established by system and local sensitization of Balb/c mice with ovalbumin . The effect of recombinant adeno?virus on the lesions of atopic dermatitis mice model was observed. Results The SPINK5 over?expressing adenovirus vector and atopic dermatitis mice model were successfully constructed. After 2 weeks of adenovirus?mediated SPINK5 gene intracutaneous injection,the redness and edema of lesions of AD model mice were obvious relieved. The pathological detection indicated that epidermal thickness and prickle cell layer ,inflammatory cell infiltration significant decreased accompanied with the model blank control. Conclusion The adenovirus?mediated SPINK5 gene had signifi?cant therapeutic effect to the atopic dermatitis mice model ,which provided a laboratory basis of application of SPINK5 gene product to therapy atopic dermatitis.

Objective To assess the changes in frequency of peripheral T lymphocytes expressing different cytokines in patients with atopic dermatitis (AD) before and after treatment with BCG-PSN and their relationship with disease severity. Methods A randomized, double blinded and placebo cross-over control study was conducted. A total of 8 patients with AD were recruited in this study. Intramuscular BCG-PSN or placebo was given to patients every other day for 36 days. Flow cytometry was performed to measure the frequency of IL4-, IL5-, IFN-γ- and TNFα-expressing peripheral CD4+ T cells and CD8+ T cells before and after the therapy. Disease severity was evaluated by atopic dermatitis area and severity index score (ADASIS). Results The difference value in IFN-γ+CD8+ T cell frequency before and after therapy was significantly higher in patients treated with BCG-PSN than in those with placebo (8.056 ± 13.962 vs -6.549 ± 10.491, U = 2.26, P< 0.05). There was no statistical difference in the frequency of IL4-, IL5-, TNFa-expressing CD8+ T cells between BCG-PSN- and placebo-treated patients (all P > 0.05). The decrease in ADASIS was 1.56 ± 1.49 in patients treated with BCG-PSN, which was statistically higher than that in placebo-treated patients (-0.05 ± 1.54, U = 2.00, P< 0.05). Conclusion As an immunomodulator, BCG-PSN may control AD by restoring the balance of T-cell subsets.
