Mitophagy is a selective autophagic process responsible for removing damaged mitochondria. In a recent review, Chinese researchers explored the molecular mechanisms that govern mitophagy and its aberrant role in the onset and progression of breast cancer. It offers a detailed overview of the dual functions of mitophagy in breast cancer advancement, investigates the potential of mitophagy-related genes and proteins as biomarkers and therapeutic targets, and emphasizes the significance of mitophagy regulators in enhancing treatment outcomes.

Acute respiratory distress syndrome (ARDS) is a devastating form of respiratory failure, still marked by high mortality due to the lack of targeted therapies. This new review synthesizes how cytokine storm drives lung injury and multiorgan dysfunction, emphasizing ARDS subphenotypes, particularly the hyperinflammatory profile. By linking mechanistic immunology with organ-specific damage and emerging immunomodulatory treatments, the authors outline a precision medicine roadmap to move ARDS care beyond purely supportive strategies.

The review by Professor Rui-Hua Xu’s team from Sun Yat-Sen University synthesizes pivotal clinical evidence to address a central challenge: while immunotherapy has revolutionized cancer care, its success varies dramatically across different gastrointestinal cancers. The authors introduce a practical "three-strata" framework that categorizes tumors based on their underlying immunobiology—from highly immunogenic to deeply immunosuppressive—and outlines distinct, optimized therapeutic strategies for each group, offering a clear roadmap for clinicians and researchers.

Podocytes are specialized cells in the kidneys that do not renew with age. Researchers from Juntendo University used electron microscopy to show that podocytes in older rats are much larger and have significant structural differences from those in young rats. These findings highlight age-related structural changes and could increase the accuracy of staging the progression of glomerular disorders in kidneys.

Central line-associated bloodstream infection (CLABSI), caused by pathogens entering the bloodstream through central venous catheters, remains a significant threat to patients in intensive care units (ICU). In response to the evolving clinical evidence and antimicrobial resistance trends, the Chinese Society of Critical Care Medicine (CSCCM) has released updated clinical guidelines for CLABSI covering its diagnosis, prevention, and treatment. Based on rigorous research and expert recommendations, the guidelines aim to standardize catheter management—supporting safer ICU care.
