The most devastating and catastrophic deterioration of myocardial ischemia-reperfusion injury (MIRI) is cardiomyocyte death. Here we aimed to evaluate the role of lncRNA-ZFAS1 in MIRI and delineate its mechanism of action. The level of lncRNA-ZFAS1 was elevated in MIRI hearts, and artificial knockdown of lncRNA-ZFAS1 in mice improved cardiac function. Notch1 is a potential target of lncRNA-ZFAS1, and lncRNA-ZFAS1 could bind to the promoter region of Notch1 and recruit DNMT3b to induce Notch1 methylation. Nicotinamide mononucleotide could promote the expression of Notch1 by competitively inhibiting the expression of DNMT3b and improving the apoptosis of cardiomyocytes and cardiac function.

Objective: miRNA, circRNA, and lncRNA play crucial roles in the pathogenesis and progression of myocardial ischemia-reperfusion injury (MI/RI). This study aims to provide valuable insights into miRNA, circRNA, lncRNA, and MI/RI from a bibliometric standpoint, with the goal of fostering further advancements in this area.
Methods: The relevant literature in the field of miRNA, circRNA, lncRNA, and MI/RI was retrieved from the Science Citation Index Expanded (SCI-E) database within Web of Science.

Background: This article aims to use high-throughput sequencing to identify miRNAs associated with ferroptosis in myocardial ischemia-reperfusion injury, select a target miRNA, and investigate its role in H9C2 cells hypoxia-reoxygenation injury.
Methods: SD rats and H9C2 cells were used as subjects. ELISA kits quantified MDA, SOD, GSH, LDH, and ferritin levels.

Neutrophil elastase (NE), a major protease in neutrophils, is important in promoting inflammation and multiple pathological processes. While NE is released abundantly in ischemiareperfusion (I/R) injury, the intricate relationship between NE and I/R injury remains unclear. We examine several aspects of how NE is involved in I/R injury.

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.

This article explored the specific mechanism by which ginsenoside Rg_1 regulates cellular autophagy to attenuate hypoxia/reoxygenation(H/R) injury in HL-1 cardiomyocytes through the microRNA155(miR-155)/neurogenic gene Notch homologous protein 1(Notch1)/hairy and enhancer of split 1(Hes1) pathway. An HL-1 cell model with H/R injury was constructed, and ginsenoside Rg_1 and/or Notch1 inhibitor DAPT and miR-155 mimics were used to treat cells. Cell counting kit(CCK)-8 was used to detect the relative viability of HL-1 cells with H/R injury.
