Purpose: Postoperative anxiety is common in surgical patients and may impair recovery, especially in the patients with preoperative anxiety. However, effective strategies for treating postoperative anxiety remain limited. We hypothesized that esketamine could reduce postoperative anxiety in patients with preoperative anxiety undergoing major abdominal tumor surgery. Patients and Methods: 180...
Nitrous oxide (N2O), commonly known as laughing gas, is widely used for its anesthetic and analgesic properties in medical settings. However, its recreational abuse has escalated, leading to severe neurological complications including cognitive impairment, yet the underlying mechanisms remain poorly understood. In this study, male C57BL/6 J mice were exposed to either normal air inhalation or...
Background: Nitrous oxide (N2O) is increasingly used as a recreational drug, leading to neurological and systemic toxicities. However, due to the rapid elimination and minimal alteration of nitrogen oxides, the short direct detection window complicates the assessment of N2O exposure. Method: In this study, we investigated the effects of chronic N2O exposure on plasma metabolites using an...
Recent clinical breakthroughs hold great promise for the application of psilocybin in the treatments of psychological disorders, such as depression, addiction, and obsessive-compulsive disorder. Psilocybin is a psychedelic whose metabolite, psilocin, is a 5-HT2A receptor agonist. Nevertheless, the underlying mechanisms for the effects of psilocybin on the brain are not fully illustrated, and...
