Effect of Perioperative Dexmedetomidine Infusion on Postoperative Delirium in Elderly Patients Undergoing Oral and Maxillofacial Surgery: A Randomized Controlled Clinical Trial.

Purpose: The aim of the study was to determine whether perioperative dexmedetomidine administration can improve postoperative delirium in elderly patients undergoing oral and maxillofacial surgery.

Patients And Methods: This was a prospective double-blind randomized controlled clinical trial conducted in Cangzhou Central Hospital from December 2021 to March 2022. Patients aged 65 and older underwent oral and maxillofacial surgery under general anesthesia.

Effects of Abdominal Wall Blocks on Postoperative Delirium in Elderly Patients Undergoing Laparoscopic Surgery: A Randomized Controlled Study.

BACKGROUND Postoperative delirium (POD) seriously affects the rapid postoperative recovery of elderly patients. We investigated the effect of abdominal wall blocks on POD in elderly patients undergoing laparoscopic radical resection of colon cancer and underlying mechanisms. MATERIAL AND METHODS A total of 100 patients undergoing laparoscopic radical resection of colon cancer were randomly assigned to group C (control) and group R (regional nerve blocks).

The Protective Activity of Penehyclidine Hydrochloride against Renal Ischemia/Reperfusion-Mediated NLRP3 Inflammasome Activation is Induced by SIRT1.

The activation of alveolar macrophages (AMs) modulated via leucine-rich repeat (NLR) pyrin domain containing 3 (NLRP3) inflammasome activation is key to the progression of renal ischemia/reperfusion (rI/R)-mediated acute lung injury (ALI). Sirtuin-1 (SIRT1) can attenuate NLRP3 inflammasome activation during I/R stress and may be an important mechanism underlying ALI pathogenesis. Penehyclidine hydrochloride (PHC), an anticholinergic drug, exerts protective effects against rI/R-mediated ALI.

Propofol ameliorates renal ischemia/reperfusion injury by enhancing macrophage M2 polarization through PPARγ/STAT3 signaling.

Propofol (Pro) confers protection against renal ischemia/reperfusion (rI/R) injury through incompletely characterized mechanisms. Since Pro has shown net anti-inflammatory properties as part of its beneficial effects, we examined the potential role of Pro in the modulation of macrophage polarization status during both rI/R injury and exposure of cultured peritoneal macrophages (PMs) to hypoxia/reoxygenation (H/R). Rats were subjected to 45-min r/IR surgery or a sham procedure and administered PBS (vehicle) or Pro during the ischemia stage.

Efficacy of Electroacupuncture Combined with Tropisetron in Treating Carboprost Tromethamine-Induced Nausea and Vomiting during Cesarean Section under Lumbar Anesthesia.

Objective: We evaluated the efficacy of electroacupuncture combined with tropisetron in treating carboprost tromethamine-induced nausea and vomiting during cesarean section under lumbar anesthesia.

Methods: A total of 264 patients aged 22-40 years were enrolled, who received carboprost tromethamine and suffered nausea and vomiting during cesarean section under lumbar anesthesia. The patients were divided randomly into the control group, electroacupuncture group, tropisetron group, and electroacupuncture + tropisetron group.

Propofol can suppress renal ischemia-reperfusion injury through the activation of PI3K/AKT/mTOR signal pathway.

Introduction: Renal ischemia/reperfusion injury (IRI) remains one of the most diseases in clinic. The purpose of this study was to investigate the potential role and mechanism of propofol in protecting mice kidney from IRI.

Methods: Renal I/R model was established in C57/BL6 mice by clamping bilateral renal pedicles for 35 min.

The protective effect of miR-377 inhibitor against renal ischemia-reperfusion injury through inhibition of inflammation and oxidative stress via a VEGF-dependent mechanism in mice.

MicroRNAs (miRNAs) play important roles in kidney development and maintenance of kidney physiological functions. MiR-377 has been reported to regulate inflammation in cardiac and cerebral ischemia. However, it remains unclear whether it has a similar function in renal ischemia/reperfusion (I/R).

Penehyclidine hydrochloride inhibits the release of high-mobility group box 1 in lipopolysaccharide-activated RAW264.7 cells and cecal ligation and puncture-induced septic mice.

Background: High-mobility group box 1 (HMGB1) is a critical mediator in the pathogenesis of many inflammatory diseases. Penehyclidine hydrochloride (PHC) has been proven to reduce sepsis-related mortality and sepsis-induced pathological complications. These effects are because of the reduced expression and release of many inflammatory mediators, although it is not clear whether PHC affects the expression and release of HMGB1.
