ObjectiveTo investigate the inhibitory effect of Biejiajian Pills （BJJW） on the growth of liver cancer， as well as its potential mechanism in mediating the AMP-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group， BJJW group （2.2 g/kg）， and metformin group （250 mg/kg）， and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment； HE staining was used to observe histopathological changes； the levels of reactive oxygen species （ROS） and adenosine triphosphate （ATP） in tumor tissue were measured； immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Tukey’s test was used for further comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the model group， the BJJW group had a tumor inhibition rate of 45.73%， with significant reductions in both tumor volume and weight （P<0.01）. Pathological examination showed that compared with the model group， the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group， the BJJW group had a significant increase in ROS level （P<0.001） and a significant reduction in ATP level （P<0.001）， as well as significant increases in p-AMPK/AMPK ratio （0.81±0.20 vs 0.13±0.04， P<0.01） and p-ULK1/ULK1 ratio （0.69±0.17 vs 0.18±0.13， P<0.01） and a significant reduction in p-mTOR/mTOR ratio （1.34±0.16 vs 3.20±0.62， P<0.01）. ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction， increasing the level of ROS， reducing the level of ATP， and activating the AMPK/mTOR signaling pathway.

Transjugular intrahepatic portosystemic shunt （TIPS） is currently an effective procedure for the complications of portal hypertension. In recent years， rapid progress has been made in the field of TIPS in terms of technical approaches， prognostic models， and an expanding range of indications. The EASL recently issued the clinical practice guidelines on TIPS to comprehensively address all aspects of TIPS in patients with liver cirrhosis. This article makes an excerpt of the key recommendations in the guidelines.

Pulpotomy, which belongs to vital pulp therapy, has become a strategy for managing pulpitis in recent decades. This minimally invasive treatment reflects the recognition of preserving healthy dental pulp and optimizing long-term patient-centered outcomes. Pulpotomy is categorized into partial pulpotomy (PP), the removal of a partial segment of the coronal pulp tissue, and full pulpotomy (FP), the removal of whole coronal pulp, which is followed by applying the biomaterials onto the remaining pulp tissue and ultimately restoring the tooth. Procedural decisions for the amount of pulp tissue removal or retention depend on the diagnostic of pulp vitality, the overall treatment plan, the patient's general health status, and pulp inflammation reassessment during operation. This statement represents the consensus of an expert committee convened by the Society of Cariology and Endodontics, Chinese Stomatological Association. It addresses the current evidence to support the application of pulpotomy as a potential alternative to root canal treatment (RCT) on mature permanent teeth with pulpitis from a biological basis, the development of capping biomaterial, and the diagnostic considerations to evidence-based medicine. This expert statement intends to provide a clinical protocol of pulpotomy, which facilitates practitioners in choosing the optimal procedure and increasing their confidence in this rapidly evolving field.

Intentional tooth replantation (ITR) is an advanced treatment modality and the procedure of last resort for preserving teeth with inaccessible endodontic or resorptive lesions. ITR is defined as the deliberate extraction of a tooth; evaluation of the root surface, endodontic manipulation, and repair; and placement of the tooth back into its original socket. Case reports, case series, cohort studies, and randomized controlled trials have demonstrated the efficacy of ITR in the retention of natural teeth that are untreatable or difficult to manage with root canal treatment or endodontic microsurgery. However, variations in clinical protocols for ITR exist due to the empirical nature of the original protocols and rapid advancements in the field of oral biology and dental materials. This heterogeneity in protocols may cause confusion among dental practitioners; therefore, guidelines and considerations for ITR should be explicated. This expert consensus discusses the biological foundation of ITR, the available clinical protocols and current status of ITR in treating teeth with refractory apical periodontitis or anatomical aberration, and the main complications of this treatment, aiming to refine the clinical management of ITR in accordance with the progress of basic research and clinical studies; the findings suggest that ITR may become a more consistent evidence-based option in dental treatment.

Tumor immune microenvironment is a local external tumor environment composed of tumor immune cells and the cytokines secreted by these cells， and it plays a regulatory role in the development and progression of tumors. In the treatment of hepatocellular carcinoma， amino acid metabolism and its reprogramming of proliferating cell metabolism have attracted more and more attention， showing potential in regulating the tumor immune microenvironment. Although amino acid metabolic reprogramming is regarded as a novel approach for tumor therapy， its specific mechanism remains unclear in the regulation of tumor immunity in hepatocellular carcinoma. This article discusses the mechanism of action of amino acid metabolism in the tumor immune microenvironment of hepatocellular carcinoma and its application prospect in clinical practice， in order to provide new ideas for immunotherapy for liver cancer.

Intrahepatic cholangiocarcinoma(ICC)is a relatively rare type of primary liver cancer,and its incidence rate has gradually increased in recent years.Due to its insidious onset and atypical clinical symptoms,most patients are already in the advanced stage of the disease at the time of confirmed diagnosis,and therefore,timely diagnosis and treatment are of great importance.Radical surgical resection is the standard treatment regimen for early-stage ICC patients,while systemic chemotherapy is the basic treatment for patients with advanced ICC and is often combined with interventional treatment,targeted therapy,and immunotherapy.This article reviews the advances in the diagnosis and treatment of ICC.

Objective To investigate the efficacy and safety of tyrosine kinase inhibitor(TKI)combined with immune checkpoint inhibitor as the second-line therapy for advanced hepatocellular carcinoma(HCC).Methods A retrospective analysis was performed for the clinical data of 63 patients with advanced HCC who were admitted to Department of Interventional Radiology,The First Affiliated Hospital of Soochow University,from January 2018 to December 2022,and all patients experienced progression/intolerance after transcatheter arterial chemoembolization combined with first-line TKI and were switched to second-line TKI with or without immune checkpoint inhibitor.The 32 patients receiving second-line TKI with immune checkpoint inhibitor were enrolled as combination group,and the 31 patients receiving second-line TKI alone were enrolled as single treatment group.Modified Response Evaluation Criteria in Solid Tumors was used to evaluate tumor response,and Common Terminology Criteria for Adverse Events 5.0 was used to evaluate adverse events.The Kaplan-Meier method was used to calculate median overall survival(mOS)and median progression-free survival(mPFS)for the two groups,and the two groups were compared in terms of objective response rate(ORR)and disease control rate(DCR).The chi-square test was used for comparison of baseline data and follow-up results between groups.Results The median follow-up time was 16.5(3.2-53.4)months for the 63 patients.The combination group had an mOS of 24.3(95%confidence interval[CI]:20.0-28.6)months and an mPFS of 9.8(95%CI:7.5-12.1)months,while the single treatment group had an mOS of 15.8(95%CI:11.4-20.1)months and an mPFS of 4.1(95%CI:3.2-4.9)months,and there were significant differences in mOS and mPFS between the two groups(P=0.029 and 0.038).The combination group had an ORR of 47%and a DCR of 84%,while the single treatment group had an ORR of 19%and a DCR of 65%;there was a significant difference in ORR between the two groups(P=0.021),but with no significant difference in DCR between the two groups(P=0.070).As for adverse events,4 patients(12.5%)in the combination group and 3(10.0%)in the single treatment group experienced grade Ⅲ-Ⅳ serious adverse events,with no fatal drug reactions in either group,and there was no significant difference in the incidence rate of adverse events between the two groups(P=0.783).Conclusion Compared with TKI alone,TKI combined with immune checkpoint inhibitor has a more significant therapeutic effect as the second-line therapy for advanced HCC,without increasing serious adverse reactions.
