Rats with experimental myocardial infarction demonstrated decrease in the activity of superoxide dismutase and catalase and increase in the content of lipid peroxidation (LPO) products and Schiff bases both in and outside the area of necrosis. The combined ischemic damage and hyperbaric oxygenation resulted in the over additive effect of accumulation of LPO products in and outside the area of infarction. The data suggest that it is desirable to use antioxidants during hyperbaric oxygenation.

Aims: Nanoplastics (NPs) are emerging organic pollutants generated by plastic degradation and are ubiquitous in the environment. They can be accumulated through the food webs and enter the human body through dietary intake, posing health risks. The main target organs of NP accumulation are the lungs, liver, heart, and kidneys.

Myocarditis, a leading cause of sudden cardiac death and heart transplantation, poses significant treatment challenges. The study of clinical samples from myocarditis patients reveals a correlation between the pathogenesis of myocarditis and cardiomyocyte mitochondrial DNA (mtDNA). During inflammation, the concentration of mtDNA in cardiomyocytes increases.

Background: Cardioimmunology is an emerging branch of medicine whose development has been facilitated by more sophisticated diagnostic procedures. Recent studies have mainly focused on the immune response during myocardial infarction (MI), and there is evidence that both resident and external immune cells participate in acute inflammatory disease, as well as tissue remodeling. Cardiac Innate Immune Cells: Following MI, macrophages, dendritic cells (DCs) and mast cells (MCs) are the main players in the heart.

Introduction: Qilong capsule (QC) has been used clinically to treat ischemic stroke in China. This study evaluated the therapeutic effects of QC on myocardial ischemia-reperfusion injury (MIRI) and its potential mechanisms.
Method: The components and candidate targets of QC against MIRI were predicted by network pharmacology via relevant databases such as TCMSP, BATMAN-TCM, GeneCards.
