In February 2025， the American Association for the Study of Liver Diseases （AASLD） published online “Critical Update： AASLD Practice Guidance on Prevention， Diagnosis， and Treatment of Hepatocellular Carcinoma”. This update mainly focuses on the latest analysis results of the IMbrave050 study and performs corresponding updates and adjustments to recommendations based on the issues in clinical practice. As for the postoperative adjuvant therapeutic strategies for hepatocellular carcinoma （HCC） based on immune checkpoint inhibitors， the AASLD has re-evaluated and updated the practice guidance. The update revises related texts and recommendations for adjuvant therapy and the management algorithms for HCC recurrence during or after adjuvant therapy. Furthermore， the AASLD emphasizes that even for HCC patients at a high risk of recurrence after resection or local ablation， close monitoring for recurrence remains the current standard treatment regimen. Our team makes an excerpt of the update， systematically introduces the background and specific contents of the update， and discuss the adjuvant therapy for HCC， in order to provide a reference for readers.

Hepatocellular carcinoma(HCC)is one of the most common malignancies with high morbidity and mortality rates worldwide.With the advances in molecular biology and tumor immunology,molecular-targeted agents represented by tyrosine kinase inhibitors(such as sorafenib and lenvatinib)and immunotherapy represented by PD-1/PD-L1 monoclonal antibodies have brought hope for patients with advanced HCC.The combination of immunotherapy and anti-angiogenic therapy can further improve the treatment outcome of patients.In addition,the optimization and integration of stereotactic body radiotherapy,local treatment,and systemic treatment may maximize the benefits of patients.In the future,through a deep understanding of the heterogeneity of HCC,the development of precision molecular subtyping and individualized treatment,and the establishment of a multidisciplinary collaborative diagnosis and treatment system,systemic therapy is expected to achieve long-term management of advanced HCC.This article reviews the current status and advances in systemic therapy for advanced HCC.

Objective To investigate the genetic characteristics and recombination of human-infected sapoviruses(SaVs)worldwide using bioinformatics.Methods The complete genome sequences of SaVs were downloaded from the National Center for Biotechnology Information(NCBI)while high-quality complete genomes were retained for analysis.Molecular phylogenetic trees of SaVs were constructed to analyze their genetic characteristics,followed by recombination analysis of human-infected SaV strains genetype Ⅰ,Ⅱ,Ⅳ,and V(G Ⅰ,G Ⅱ,GⅣ,and GⅤ)with recombination analysis software.Results SaVs exhibited substantial genetic diversity worldwide and infected a wide range of hosts.Human-associated SaVs included G Ⅰ,G Ⅱ,GⅣ,and GⅤ,with GⅤ shared between human and swine hosts.Genetype recombination analysis of SaVs revealed a high frequency of recombination in SaV G Ⅱ strains that involved diverse hosts in the field of SaV G V strains.Recombination breakpoints of the virus were concentrated in the major viral proteins 1(VP1)and minor viral proteins 2(VP2).Conclusion Based on systematic analysis of the genetic characteristics of human-infected SaVs,the genotype distribution and prevalence of SaVs are investigated,the recombination patterns of SaV revealed,and its genetic dynamics highlighted.These findings can offer insights into epidemiological trends of viruses and help devise effective prevention and control strategies.

Biliary tract carcinoma （BTC） is a type of gastrointestinal tumor with a low incidence rate and a strong invasive ability， mainly including intrahepatic cholangiocarcinoma （ICC）， extrahepatic cholangiocarcinoma （ECC）， and gallbladder carcinoma （GC）， often accompanied by local progression or distant metastasis. Surgery is often the preferred treatment method for patients with local resectable tumor； however， there is still a high risk of recurrence after radical surgery. Therefore， multiple treatment modalities are often required for BTC patients， including surgical resection， systemic treatment （such as targeted therapy， chemotherapy， and immunotherapy）， and/or a combination of local treatment methods. With the development of the field of BTC， it is critical for surgical oncologists to understand and master the latest surgical strategies and the best patient selection and management systems. In view of the complexity of treatment and the continuous development of diagnosis and treatment techniques， Annals of Surgical Oncology， an authoritative American journal of cancer surgery， recently published the practical diagnosis and treatment guidelines for hepatobiliary tumors， including hepatocellular carcinoma （HCC）， ICC， ECC， and GC， aiming to provide more evidence-based evidence for the clinical management and decision-making of patients with hepatobiliary tumors. Due to the limitations of length and different emphases， this article mainly introduces the recommendations for the evaluation points and clinical treatment of ECC and GC in the guidelines， so as to provide a reference for clinical practice.

In recent years， transcatheter arterial chemoembolization （TACE） has emerged as a common treatment modality for the treatment of hepatocellular carcinoma （HCC）. However， with the ongoing development of embolic agent techniques， the new advances in microspheres and nanoparticles have brought new hope for improving the efficacy and safety of TACE. This article reviews the latest advances and applications of microspheres and nanoparticles in TACE for HCC. First， this article introduces the background of TACE as a therapeutic approach and the emergence of microsphere and nanoparticle techniques， and then it describes the application of various types of microspheres and nanoparticles in TACE and discusses the requisite attributes of an ideal embolic agents. The article focuses on the advances in material science and engineering， as well as the clinical efficacy of drug-eluting microspheres and nanoparticles versus conventional TACE. Furthermore， it discusses the importance of radiological examination in TACE and summarizes the research advances in the radiopaque and magnetic resonance-visible embolic agents. This article also explores the future development directions and challenges of TACE. It also points out the combination of microspheres and nanoparticles with other treatment modalities， the application of personalized and precision medicine in TACE， and the potential regimen of TACE in clinical translation， and meanwhile， it raises the issues of ethics and regulation that need to be further discussed. It is believed that microspheres and nanoparticles have a potential effect in TACE， which provides a theoretical basis and technical support for innovating HCC treatment regimens and improving the prognosis of patients through TACE interventions.

Primary liver cancer is a highly malignant tumor of the digestive tract, charac-terized by an insidious onset and frequently accompanied by local progression or distant metastasis. Although surgical resection is typically the optimal treatment for patients with locally resectable tumors, the major challenge in achieving long-term survival prognosis lies in the high postoperative recurrence rate. Due to the substantial heterogeneity and complexity of primary liver cancer, a multimodal comprehensive treatment approach involving surgical resection, systemic therapy ( e.g., targeted therapy, chemotherapy, immunotherapy), and/or local treatment is commonly employed. As research regarding primary liver cancer continues to progress, it becomes crucial for surgical oncologists to acquire a deep understanding and proficiency in the latest surgical diagnostic and treatment methods, along with optimal patient selection and management strategies. The authors aim to comprehensively elaborate on the latest practice guidelines for surgically treatment of primary liver cancer and systematically outline the key points in evaluating primary liver cancer, primarily focusing on hepatocellular carcinoma and intrahepatic bile duct carcinoma, and offer pertinent recommendations for clinical treatment, thus providing robust evidence in the clinical management and decision-making for patients with primary liver cancer.

Hepatocellular carcinoma (HCC) is the most common primary hepatic malign-ancy in clinic. The prognosis of patients remains extremely poor because of the high malignancy and easy recurrence and metastasis of HCC. In recent years, the roles of platelets in promoting the malignant progression of HCC have increasingly attracted much attention. It is known that platelets could promote HCC cells proliferation and invasion through tumor microenvironment. On the other hand, platelets are capable to promote HCC cells distant metastasis by facilitating tumor cells evasion of immune surveillance. Besides, the platelet-derived growth factors and proangiogenic factors are also involved in the proliferation, invasiveness, and neovascularization of HCC. In addition, patients with HCC normally have a background of cirrhosis, and it is still controversial that whether the thrombocytopenia by portal hypertension and hypersplenism can promote the malignant progress of HCC. In view of this, the diagnostic and prognostic value of platelet levels, as well as platelet-associated scores in HCC have increasingly become research focus. The authors elaborate the detailed mechanisms of platelets in malignant progression of HCC, and discuss the recent research progress of platelets as effective diagnostic or prognostic tools for the assessment of HCC, which is of great importance to optimize the current treatment regimen and explore novel therapeutic strategies against HCC.

In October 2022, the European Society for the Study of the Liver (EASL) publishes officially the EASL Clinical Practice Guidelines on the management of cystic liver diseases, which covers the diagnosis, treatment, and management of hepatic cysts, mucinous cystic neoplasms of the liver, biliary hamartomas, polycystic liver disease, Caroli disease, Caroli syndrome and peribiliary cysts. Combined with the contrast-enhanced imaging examination, the guideline is of great significance for standardized diagnosis and treatment of hepatic cystic lesions. The authors interpret the guideline in detail, and systematically introduce the key points of assessment of various types of cystic liver disease and related recommendations for treatment. Meanwhile, the future applications and research directions are further prospected in order to provide more evidence basis for the clinical manage-ment and decision-making for patients with cystic liver diseases.

Only 9.61%(22/229) of surgeons did not require help. Commercial advertisement was allowed by 40.17%(92/229) of surgeons and forbidden by 59.83%(137/229) of surgeons. In terms of alternative suggestion, 70.74%(162/229) of surgeons believed that it was necessary for the We-Media platforms to involve more doctors of different specialties, but 40.61%(93/229) of surgeons believed that relevant departments or associations should strengthen supervision under the current situation. In addition, 32.75%(75/229) of surgeons believed that the operation of We-Media platform requires more investment. The were 27.95%(64/229) of surgeons giving specific suggestions on running We-Media platforms, 7.81%(5/64) of which did not suggest a blind try.Conclusions:Most surgeons who open and operate We-Media platforms in China are faced with problems such as busy work, limited time and energy, low-income increase, and lack of professional promotion and maintenance teams and external support. Even so, there are still many surgeons who have achieved success through long-term persistence and high-quality content output, thus increasing the number of patient visits, improving their own ability and industry influence, and bringing a greater sense of professional achievement.

MicroRNA-132 (miR-132), a small RNA that regulates gene expression, is known to promote neurogenesis in the embryonic nervous system and adult brain. Although exposure to psychoactive substances can increase miR-132 expression in cultured neural stem cells (NSCs) and the adult brain of rodents, little is known about its role in opioid addiction. So, we set out to determine the effect of miR-132 on differentiation of the NSCs and whether this effect is involved in opioid addiction using the rat morphine self-administration (MSA) model. We found that miR-132 overexpression enhanced the differentiation of NSCs in vivo and in vitro. Similarly, specific overexpression of miR-132 in NSCs of the adult hippocampal dentate gyrus (DG) during the acquisition stage of MSA potentiated morphine-seeking behavior. These findings indicate that miR-132 is involved in opioid addiction, probably by promoting the differentiation of NSCs in the adult DG.
