Introduction: Impairment of learning and memory caused by sleep deprivation is a common symptom that significantly affects quality of life. Repetitive transcranial magnetic stimulation (rTMS) is a promising approach to exert a positive effect on cognitive impairment. However, there is less known about the mechanism of rTMS for learning and memory induced by chronic REM sleep deprivation (CRSD).

Methods: Hepatic apex resection was performed under propofol-based total intravenous anesthesia. Male Sprague-Dawley rats were subjected to EA treatment or EA + mitochondrial division inhibitor-1 (mdivi-1) treatment once a day for three consecutive days after surgery.
Unlabelled: The authors present the clinical case of a 67-year-old man with severe insomnia for 5 years with an exacerbation about 1 year before consultation. He did not have enough concentration and energy for his daily work and developed depression and anxiety because of his excessive daytime sleepiness. During his insomniac state, a drug treatment provided partial relief, but the effects were not long-lasting.

Based on the principles of PCA, we developed Patient-Controlled Sleep (PCSL) for chronic intractable insomnia where the traditional analgesics in PCA were replaced with dexmedetomidine (Dex), an alpha-2 agonist widely used for premedication, sedation, anxiolysis and analgesia. The purpose of this study was to assess the feasibility of the new method for the treatment of chronic intractable insomnia.

This study evaluated the efficacy and safety of nalbuphine for the treatment of postoperative pain after ambulatory surgery, relative to tramadol.
Methods: This multi-center, randomized, double blind, and controlled study was conducted at 10 centers.
Background: Thalamic pain is a neuropathic pain syndrome that occurs as a result of thalamic damage. It is difficult to develop therapeutic interventions for thalamic pain because its mechanism is unclear. To better understand the pathophysiological basis of thalamic pain, we developed and characterized a new rat model of thalamic pain using a technique of microinjecting cobra venom into the ventral posterolateral nucleus (VPL) of the thalamus.

Here we tested the molecular mechanisms of memory loss in hippocampus of rat POCD model. We found that high-dose propofol anesthesia significantly alleviated spatial memory loss.

We conducted this study to assess the antiemetic properties of propofol for the prevention and immediate treatment of post-delivery nausea and vomiting during cesarean section under combined spinal-epidural anesthesia.
Methods: Eighty women undergoing elective cesarean delivery under combined spinal-epidural anesthesia were randomized to receive either propofol at a plasma concentration of 1000 ng/mL or normal saline immediately after clamping of the umbilical cord.
Inflammatory and neurotrophic factors are involved in postherpetic neuralgia (PHN), but the association of these factors in the cerebrospinal fluid (CSF) with the level of pain is poorly known. The present study aimed to examine the changes in neurotrophic and inflammatory factors in the CSF of patients with PHN and to study the correlation between these factors and the degree of pain. Fifty patients with PHN and 28 patients with hemifacial spasm (as controls) were recruited between May 2015 and March 2016.

We tested and extended the model by observing the ultrastructural alterations of neurons and ameliorative effect of pregabalin in cobra venom-induced pain behaviors of rats.
Objectives: The goal of this study was to prove the feasibility of the cobra venom-induced model of trigeminal neuralgia and to demonstrate the demyelination change of ION and medulla oblongata is the major pathological change of trigeminal neuralgia.
Objectives: Electroconvulsive therapy (ECT) has dramatically reduced musculoskeletal complications when carried out with muscle relaxants under general anesthesia. However, seizure quality can be affected by the depth of anesthesia and choice of anesthetic agent. The purpose of this study was to describe a general anesthetic technique for ECT by using laryngeal mask, bispectral index (BIS), and muscle relaxant monitoring.

Methods: Fifty-eight adult male Sprague-Dawley rats were randomly divided into 5 groups. Under pentobarbital sodium anesthesia, cobra venom was injected into the lower trunk or sham operation was performed in the animals.
Background: A few studies on the depth from the skin to the cervical epidural space (DSES) have been reported from the United States, South Korea, Japan, and Taiwan. There are no published reports from mainland China.
Objectives: The goal of this study was to collect standard data on Chinese adults from mainland China in a large medical center with a wide geographical range of patients.

Objective: To investigate the effects of intravenous administration of dexamethasone on early postoperative cognitive dysfunction (POCD).
Methods: In this prospective randomized trial, 1000 patients with facial spasm undergoing microvascular decompression (MVD) were randomly assigned to receive normal sodium (Dex-0 group, n=333), dexamethasone 0.1 mg/kg (Dex-1 group, n=333), or dexamethasone 0.

Background: Spinal epidural hematoma (SEH) is a rare but acute and possibly devastating clinical event. The purpose of this study is to assess the multiple etiologies of SEH seen in an academic medical center over a 15-year span. We have examined the etiologies of SEH occurring in a single institution, the University of Pittsburgh Medical Center (UPMC) over the last fifteen years using an electronic record keeping system and database: the Medical Archive Retrieval System (MARS).

Methods: Ninety-six patients with facial spasm who were scheduled to receive microvascular decompression were randomly divided into 2 groups: deeper anesthesia (n = 50) and lighter anesthesia (n = 46). Exclusion criteria included: a history of neurologic or mental disease, serum creatinine in excess of 177 μmol/L, active liver disease, cardiac dysfunction, pulmonary dysfunction, endocrine disease, metabolic disease, a history of surgery, fewer than 6 years of school, inability to complete neuropsychologic testing, vision dysfunction, and auditory dysfunction.
