Unexpected pheochromocytoma leading to cardiac arrest during the perioperative period: a case report and literature review.

Background: Pheochromocytomas (PCCs) are rare neuroendocrine catecholamine (CA)-secreting tumours that originate from chromaffin tissue and can produce and store CAs. Unexpected PCCs pose a serious threat to the perioperative safety of patients and a considerable challenge to anaesthesiologists because of the risks of fatal hypertensive crises and other stresses.

Case Presentation: A 37-year-old woman who was scheduled for tonsillectomy and palatopharyngoplasty under general anaesthesia experienced a malignant cardiovascular event after induction, which was characterized mainly by a sharp increase in heart rate and blood pressure, ultimately leading to cardiac arrest and the occurrence of secondary long QT syndrome.

Remimazolam tosilate compared with propofol for gastrointestinal endoscopy in elderly patients: a prospective, randomized and controlled study.

Background: Remimazolam tosilate (HR7056, RT), a novel ultrashort-acting benzodiazepine, can be used for procedural sedation and general anaesthesia. However, few studies have focused on the sedative effect of RT during gastrointestinal endoscopy in elderly patients. The purpose of this study is to compare the sedative effect of RT and propofol for gastrointestinal endoscopy in elderly patients.

Risk Factors for Outcomes After Microvascular Decompression for Trigeminal Neuralgia.

Background: Microvascular decompression (MVD) has been the most effective long-term surgical treatment of trigeminal neuralgia (TN). However, the risk factors for poor pain control after MVD are not fully understood.

Methods: A total of 184 patients with typical TN who had undergone MVD at our institution from January 3, 2008 to January 3, 2016 were enrolled in the present study.

Abnormal increase of miR-4262 promotes cell proliferation and migration by targeting large tumor suppressor 1 in gliomas.

Background: miRNA was recently detected as tumor suppressor or inducer in various cancers including gliomas. Due to the abnormal expression of miR-4262 in glioma cancer, we supposed that miR-4262 made efforts in proliferation and migration in glioma cancer.

Methods: CCK-8, Transwell migration Assay and Wound-healing assay were appraisal assays for cell proliferation and migration.

Behavioral and neurophysiological abnormalities during cued continuous performance tasks in patients with mild traumatic brain injury.

Objective: This study's aim was to investigate the features and neural mechanisms of sustained attention in patients with mild traumatic brain injury (mTBI) by comparing and analyzing neuropsychological, behavioral, event-related potentials, and event-related desynchronization and synchronization between mTBI patients and healthy controls.

Methods: Twenty mTBI patients with mTBI and 20 healthy controls underwent the Mini-Mental State Examination (MMSE) and a cued continuous performance task (AX-CPT). Neuropsychological, behavioral, and electroencephalogram (EEG) data were collected and analyzed.
