Oral-Periodontal Evaluation and Assessment of Oral Fluid Biomarkers in Patients With Hepatitis B+D

Periodontal disease is a chronic inflammatory condition associated with systemic diseases, highlighting the concept of periodontal medicine. This study aims to investigate the relationship between periodontal inflammation, oral lesions, and hepatitis B+D infection, with or without bulevirtide treatment. Oral-periodontal clinical parameters and targeted inflammatory biomarkers in saliva and gingival crevicular fluid will be evaluated in three groups: patients with hepatitis B+D receiving bulevirtide, patients with hepatitis B+D not receiving bulevirtide, and healthy controls.

Effect of Fufang Biejiaruangan Combined With Antiviral Therapy on the Incidence of Hepatocellular Carcinoma in Patients With Hepatitis B-related Cirrhosis: A Multicenter, Randomized, Placebo-controlled Study

This study aims to establish a prospective, multicenter, randomized, double-blind, placebo-controlled parallel-group clinical trial cohort. The cohort will include high-risk populations for hepatitis B cirrhosis-related hepatocellular carcinoma (HCC) from multiple centers nationwide, who meet the criteria of traditional Chinese medicine syndrome differentiation as Qi-zhi-xue\_yu syndrome and have an aMAP score \>60 points. The objective is to evaluate whether combining Bie-jia-ruan-gan with standard anti-hepatitis B virus therapy can further reduce the incidence of HCC in this high-risk population.

Comparison of a Handheld Elastography Device With iLivTouch in Chronic Liver Disease Patients

This single-center cross-sectional study aims to evaluate the agreement between a handheld elastography device and the iLivTouch transient elastography system for the noninvasive assessment of liver fibrosis and steatosis in adults with chronic liver disease. The study compares liver stiffness measurement (LSM) and ultrasound attenuation parameter (UAP) obtained by both devices in the standard supine position, and further explores the feasibility and consistency of measurements performed in the sitting position. All participants will undergo paired examinations using both devices in two body positions (supine and sitting). Agreement between devices and between body positions will be assessed using Bland-Altman analysis, intraclass correlation coefficients, and categorical consistency metrics. The study will also evaluate device performance indicators, including measurement success rate, procedure time, and battery endurance under simulated clinical conditions. This study aims to provide clinical evidence on the accuracy, reliability, and feasibility of a new handheld transient elastography device, and to explore whether sitting-position measurements can serve as an alternative to standard supine assessment in chronic liver disease patients.

Phase 1 Study to Evaluate Safety and Antiviral Activity of PBGENE-HBV in Adult Patients With Chronic Hepatitis B

This is a Phase 1, open-label, dose escalation and dose expansion study to evaluate the safety, tolerability, PK, and antiviral activity of PBGENE-HBV in adult participants with chronic hepatitis B.
