Epstein-Barr virus mRNA vaccine synergizes with NK cells to enhance nasopharyngeal carcinoma eradication in humanized mice.

The close association between nasopharyngeal carcinoma (NPC) and Epstein-Barr virus (EBV) infection highlights the potential of therapeutic vaccination against viral antigens as an attractive immunotherapy for treating EBV NPC. Maximizing vaccine efficacy often requires selecting optimal T cell epitopes and incorporating co-treatment strategies. Here, we analyzed genomic mutations of 283 cancer-associated EBV strains and predicted epitopes with broad human leukocyte antigen (HLA) coverage from high-frequency nonsynonymous mutations.

Trimetallic-doped carbon nitride achieves chondroitin sulfate degradation via a free radical degradation strategy.

Traditional Fenton principles for degrading polysaccharides, including chondroitin sulfate (CS), are fraught with limitations, such as strict pH-dependence, higher temperature requirements, desulfurization, and environmentally perilous. In this study, an effective Fenton-like system comprising trimetallic-doped carbon nitride material (tri-CN) with hydrogen-bonded melamine-cyanuric acid (MCA) supramolecular aggregates as its basic skeleton was engineered to overcome the challenges of traditional methods. Detailed material characterizations revealed that, compared to monometallic-doped or bimetallic-doped counterparts, tri-CN offered a larger surface area, higher porosity, and increased metal loading, thereby enhancing reactant accessibility and polysaccharide degradation efficiency.

Enzyme-mediated green synthesis of glycosaminoglycans and catalytic process intensification.

Glycosaminoglycans (GAGs) are a family of structurally complex heteropolysaccharides that play pivotal roles in biological functions, including the regulation of cell proliferation, enzyme inhibition, and activation of growth factor receptors. Therefore, the synthesis of GAGs is a hot research topic in drug development. The enzymatic synthesis of GAGs has received widespread attention due to their eco-friendly nature, high regioselectivity, and stereoselectivity.

Clinical practice of basin-shaped hepaticojejunostomy following hilar resection of stage III/IV hilar cholangiocarcinoma.

Background: Radical surgery for Bismuth type III/IV hilar cholangiocellular carcinoma, which was usually considered unresectable, seems to improve prognosis by increasing the surgical curability rate. However, the dilemma of multiple billiary stumps and high postoperative complication rate caused by hepato-enteric anastomosis has been the main impediment. Thus, we practiced and introduce a new technique called "basin-shaped" hepaticojejunostomy to improve the treatment.

Background: Patients with intermediate to advanced hepatocellular carcinoma (HCC) are most commonly treated with transarterial chemoembolization (TACE). Previous studies showed that TACE combined with recombinant human adenovirus type 5 (H101) may provide a clinical survival benefit. In the present study, we aimed to determine the survival benefit of TACE with or without H101 for patients with intermediate to advanced HCC and to develop an effective nomogram for predicting individual survival outcomes of these patients.

Inflammation scores predict the survival of patients with hepatocellular carcinoma who were treated with transarterial chemoembolization and recombinant human type-5 adenovirus H101.

Background: The systemic inflammatory response plays an important role in cancer development and progression. An original inflammation-based staging system for predicting survival in patients undergoing transarterial chemoembolization (TACE) combined with recombinant human type-5 adenovirus H101 is not available. This study aimed to validate the prognostic value of inflammation scores for patients with hepatocellular carcinoma (HCC) who were treated with TACE combined with H101.

Changes of HBV DNA After Chemoembolization for Hepatocellular Carcinoma and the Efficacy of Antiviral Treatment.

Unlike systemic chemotherapy for hematological malignancies with hepatitis B virus (HBV) infection, transarterial chemoembolization (TACE) for HBV-related hepatocellular carcinoma (HCC) has only recently been reported to cause HBV reactivation and subsequent hepatitis. Most patients with HBV-related HCC have an underlying disease with liver fibrosis or cirrhosis, and TACE may potentially induce HBV reactivation and liver decompensation. Currently, there are no clinical guidelines for managing TACE-caused HBV reactivation.
