Analysis of Changes of Ang-2 and TNF-α Levels in Patients with AMI Complicated with Pulmonary Infection and Drug Resistance of Infectious Pathogens.

Objective: This study aimed to investigate the changes in angiopoietin-2 and tumor necrosis factor α levels in patients with acute myocardial infarction complicated with pulmonary infection.

Methods: Retrospective selection was conducted on 61 patients with acute myocardial infarction complicated with pulmonary infection and 122 patients with simple acute myocardial infarction. A comparison was made between the two groups regarding general information and serum myocs.

PI3K/Akt/uncoupling protein 2 signaling pathway may be involved in cell senescence and apoptosis induced by angiotensin II in human vascular endothelial cells.

Oxidative DNA damage contributes to replicative senescence. We explored the mechanism by which angiotensin II (Ang II) induces senescence in human vascular endothelial cells (HUVECs). Following weeklong incubation with Ang II, cell senescence, apoptosis, reactive oxygen species (ROS) content and mitochondrial membrane potential (MMP) were measured by β-galactosidase, annexin V/propidium iodide, DCFH-DA and rhodamine 123 staining, respectively.
