Case Report: Left ventricular assist device implantation combined with cryoballoon ablation for ventricular tachycardia.

We report a case of a patient with dilated cardiomyopathy who experienced recurrent ventricular tachycardia (VT) and multiple defibrillations following CRT-D implantation. Due to worsening cardiac function, the patient required surgical implantation of a left ventricular assist device (LVAD) as a bridge to heart transplantation. During the procedure, we used the Ensite three-dimensional mapping system to perform activation and substrate mapping of the VT targets, followed by endocardial and epicardial cryoballoon ablation of clinical VT.

Circulating levels of adiponectin and AdipoR expression in peripheral blood mononuclear cells are associated with lower respiratory tract Infection.

Objective: The role of adiponectin (APN) in regulating inflammation is well recognized in metabolic disease, but the dysregulation of APN in lower respiratory tract infection (LRTI) remains controversial. We aimed to measure APN and its signaling receptors, adiponectin receptor (AdipoR), in peripheral blood mononuclear cells (PBMCs) from LRTI patients to explore their potential roles in the LRTI process.

Methods: A total of 99 LRTI patients from the Second Xiangya Hospital of Central South University were categorized into acute (n=35) and non-acute (n=64), and non-severe (n=62) and severe (n=37) groups.

C-X-C chemokine receptor type 5CD8 T cells as immune regulators in hepatitis Be antigen-positive chronic hepatitis B under interferon-alpha treatment.

Background: C-X-C chemokine receptor type 5 (CXCR5)CD8 T cells represent a unique immune subset with dual roles, functioning as cytotoxic cells in persistent viral infections while promoting B cell responses. Despite their importance, the specific role of CXCR5CD8 T cells in chronic hepatitis B (CHB), particularly during interferon-alpha (IFN-α) treatment, is not fully understood. This study aims to elucidate the relationship between CXCR5CD8 T cells and sustained serologic response (SR) in patients undergoing 48 weeks of pegylated IFN-α (peg-IFN-α) treatment for CHB.

Enhanced hydrogel loading of quercetin-loaded hollow mesoporous cerium dioxide nanoparticles for skin flap survival.

Flap techniques are indispensable in modern surgery because of their role in repairing tissue defects and restoring function. Ischemia-reperfusion and oxidative stress-induced injuries are the main causes of flap failure. Oxidative stress exacerbates cell damage through the accumulation of reactive oxygen species (ROS), thereby affecting flap function and survival.

Single-cell RNA Sequencing Revealed the Immunophenotypic Features of Macrophages in Cardiac Transplants and Uncovered Lgals9 Promoted Their Polarization towards The M2b Subtype.

Macrophages play a crucial role in the immune response during allograft rejection in organ transplantation. Therefore, our study aimed to explore the genomic features of macrophages in mouse heart transplants and use single-cell RNA sequencing to investigate Galectin-9 (Gal-9, Lgals9), a lectin that can mediate the activation and differentiation of immune cells through ligand-receptor interactions, and the effects of its regulation in transplantation. We discovered a new subset of macrophages called "Myoz2+ macrophages", which specifically expressed genes related to myocardial contraction.

Aberrant STING activation promotes macrophage senescence by suppressing autophagy in vascular aging from diabetes.

Diabetic vascular aging is driven by macrophage senescence, which propagates senescence-associated secretory phenotypes (SASP), exacerbating vascular dysfunction. This study utilized a type 2 diabetes mellitus (T2DM) mouse model induced by streptozotocin injection and a high-fat diet to investigate the role of STING in macrophage senescence. Vascular aging markers and senescent macrophages were assessed , while , high glucose treatment induced macrophage senescence, enhancing senescence in co-cultured vascular smooth muscle cells.
