Objective: To study the effect of of percutaneous para-toluenesulfonamide (PTS) injection on transplanted hepatocarcinoma in nude mice.
Methods: Sixty nude mice with subcutaneous transplanted hepatocarcinoma were randomized into 6 groups, namely PTS, chemotherapy, radiotherapy, PTS+chemotherapy, PTS+radiotherapy and control groups. PTS were injected into the tumor in the nude mouse models as indicated, and the tumor growth rate and survival time of the mice were recorded.
Results: All the treatments resulted in effective arrest of the tumor growth, but the effects of PTS+chemotherapy and PTS+radiotherapy were more obvious. No significant difference in the survival time of the mice were noted between the groups.
Conclusion: PTS+chemotherapy and PTS+radiotherapy are safe and reliable, and produces better effects than either radiotherapy or chemotherapy alone.

Objectives: Liver transplant (LT) is an effective treatment for hepatocellular carcinoma (HCC) in appropriately selected patients. Locoregional therapy (LRT) is often performed to extend a patient's eligibility for LT. Imaging has a modest sensitivity of approximately 40-77% for detecting pathologically viable HCC in post-LRT patients.

Introduction: Resistance to lenvatinib limits the effectiveness of the targeted treatments for HCC. However, the exact mechanism behind this resistance remains elusive. Current research suggests that circular RNA (circRNA) is pivotal in mediating drug resistance during targeted treatments.

Hepatitis C virus (HCV) infects both pediatric and adult populations and is an important cause of chronic liver disease worldwide. There are differences in the screening and management of HCV between pediatric and adult patients, which have been highlighted in this review. Direct-acting antiviral agents (DAA) have made the cure of HCV possible, and fortunately, these medications are approved down to three years of age.

Liver tumors represent a serious clinical health problem that threatens human life. Previous studies have demonstrated that the pathogenesis of liver tumors is complex and influenced by various factors, highlighting limitations in both basic pathological research and clinical treatment. Traditional research methods often begin with the discovery of phenomena and gradually progress to the development of animal models and human trials.
