Sufentanil, a commonly used opioid analgesic, could mimic ischemia postconditioning to attenuate ischemia reperfusion injury, but this effect might be hindered in diabetic animals by inhibition of glycogen synthase kinase-3β phosphorylation. Also, diabetes can abrogate the cardioprotection of sevoflurane (an inhaled anesthetic) against ischemia reperfusion(More)
The output of the neuronal digital spikes is fulfilled by axonal propagation and synaptic transmission to influence postsynaptic cells. Similar to synaptic transmission, spike propagation on the axon is not secure, especially in cerebellar Purkinje cells whose spiking rate is high. The characteristics, mechanisms and physiological impacts of propagation(More)
BACKGROUND Opioid-induced cough during induction of general anesthesia is a common phenomenon. Dezocine, a partial μ-receptors agonist and κ-receptors antagonist, has been documented effectively suppressing fentanyl-induced cough in general anesthesia induction. However, the effect of dezocine on sufentanil-induced cough is still unknown. METHODS A total(More)
OBJECTIVE The aim of this study was to compare the effects of anesthesia by dexmedetomidine and propofol on the hemodynamics and oxygen balance in children with complex congenital heart disease who were undergoing cardiac surgery. METHODS Fifty-seven children were randomized to receive either a continuous infusion of propofol (6-8 mg/kg/h) or(More)
The cellular mechanisms underlying amnesia produced by the analgesic ketamine are not clear. The current study examined the effects of ketamine on memory consolidation in rats trained in a Morris water maze task, and further tested whether the glycogen synthase kinase (GSK)3β/β-catenin signaling pathway was involved in mediating the effects of posttraining(More)
BACKGROUND Remote precoditioning of trauma (RPCT) confers cardioprotective effects against myocardial ischemia/reperfusion injury, which are mediated by spinal opioid receptors. The aim of this study was to identify the roles of opioid receptor subtypes in the cardioprotective effect of RPCT and possible mechanisms. METHODS In this study, 192(More)
The possible adverse effects of engineered nanomaterials on human health raise increasing concern as our research on nanosafety intensifies. Upon entry into a human body, whether intended for a theranostic purpose or through unintended exposure, nanomaterials tend to accumulate in the liver, leading to hepatic damage. A variety of nanoparticles, including(More)
BACKGROUND/OBJECTIVE Inadvertent intraoperative hypothermia (core temperature <36°C) is a frequently preventable complication with several adverse consequences. Our study aimed to determine the overall incidence of inadvertent intraoperative hypothermia and its risk factors associated with clinical outcomes in this national survey in China. METHODS We(More)
OBJECTIVE This study investigated the effects of aortic root infusion of sufentanil on myocardial ischemia/reperfusion injury in patients undergoing elective mitral valve replacement (MVR) with cardiopulmonary bypass (CPB). DESIGN A prospective, randomized, clinical study. SETTING A university-affiliated teaching hospital. PARTICIPANTS Fifty-three(More)
