[Research progress in polysaccharide-modified lipid nanoparticles for drug delivery].

Lipid nanoparticles serve as a promising drug delivery system due to the good biocompatibility, non-immunogenicity, and high drug loading efficiency. However, unmodified lipid nanoparticles have limitations such as poor stability, easy hydrolysis, and rapid removal. To overcome these shortcomings, researchers have developed peptide modification, antibody modification, ligand modification, nucleic acid aptamer modification, and polysaccharide modification for lipid nanoparticles.

Design, Synthesis, and Biological Evaluation of 3,4-Dihydroisoquinolin-1()-one Derivatives as Protein Arginine Methyltransferase 5 Inhibitors for the Treatment of Non-Hodgkin's Lymphoma.

Through catalyzing the transfer of methyl groups onto the guanidinium of arginine, protein arginine methyltransferase 5 (PRMT5) was essential to the cell growth of cancer cells. By utilizing a scaffold hopping strategy, a novel series of 3,4-dihydroisoquinolin-1()-one derivatives were designed and synthesized. Through a systematic SAR study, demonstrated excellent PRMT5 inhibitory activity, potent antiproliferative activity against Z-138, favorable pharmacokinetic profiles, and low hERG toxicity.

Expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Quercetin Promote the Chemosensitivity in Organoids Derived from Patients with Breast Cancer.

Aim: The study aimed to culture organoids from tissues of patients with breast cancer (BC) and use the organoids to measure the sensitivity to quercetin and its combination with chemotherapeutic agents.

Methods: Four patient-derived organoids (PDOs) of BC were cultured. The proliferative activity and morphology of PDOs were evaluated on different generations and after resuscitation.

Expression of lipid metabolism and cartilage degeneration-related factors in lumbar vertebral endplate Modic changes.

Objectives: This study aims to investigate the relationship between the expression of lipid metabolism and cartilage degeneration-related factors and Modic changes (MCs) of lumbar vertebral.

Patients And Methods: This prospective study included a total of 10 patients (6 males, 4 females; mean age: 60.4±8.
