Efficacy of quadratus lumborum block in the treatment of acute and chronic pain after cesarean section: A systematic review and meta-analysis based on randomized controlled trials.

Background: This analysis aimed to explore the analgesic effects of quadratus lumborum block on acute and chronic postoperative pain among patients undergoing cesarean section.

Methods: PubMed, Cochrane, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP databases for Randomized Controlled Trials (RCTs) that focused on the use of quadratus lumborum block in cesarean section procedures were searched from the inception of the databases until December 2022. Studies were screened based on inclusion and exclusion criteria, and were then conducted for quality assessment and data extraction.

Propofol inhibits cell apoptosis and inflammatory response in ox-LDL-induced human umbilical vein endothelial cells through the modulation of the circ_0003645/miR-149-3p/TRAF7 axis.

Background: Propofol is an anesthetic agent and can impede the progression of human diseases. Circular RNA (circRNA) circ_0003645 has been identified to promote the development of atherosclerosis (AS). This study aimed at the functional mechanism of propofol and circ_0003645 in AS.
