Objective To evaluate the effectiveness of preemptive multimodal analgesiain elderly patients undergoing laparoscopic colorectal surgery. Methods A prospective randomized controlled study was conducted in the Department of Gastrointestinal Surgery of the Second Hospital of Hebei Medical University from January 2022 to December 2022. A total of 133 patients were included according to the criteria and randomly divided into preemptive analgesia (PRA) group (test group, 67patients) and postoperative analgesia (POA) group (control group, 66patients).

USP22 Protects Against Myocardial Ischemia-Reperfusion Injury via the SIRT1-p53/SLC7A11-Dependent Inhibition of Ferroptosis-Induced Cardiomyocyte Death.

Myocardial ischemia-reperfusion (MI/R) injury is characterized by iron deposition and reactive oxygen species production, which can induce ferroptosis. Ferroptosis has also been proposed to promote cardiomyocyte death. The current study sought to define the mechanism governing cardiomyocyte death in MI/R injury.
