Natural Growth Dynamics of Untreated Skull Base Chordomas In Vivo.

Objective: To study the natural growth dynamics of skull base chordomas.

Methods: A retrospective study of skull base chordomas was performed. Patients with ≥2 preoperative magnetic resonance (MR) images and with pathologically confirmed chordomas were enrolled.

Efficacy of Acupuncture Combined with Local Anesthesia in Ischemic Stroke Patients with Carotid Artery Stenting: A Prospective Randomized Trial.

Objective: To evaluate the efficacy of electro-acupuncture (EA) or transcutaneous electrical acupoint stimulation (TEAS) on perioperative cerebral blood flow (CBF) and neurological function in ischemic stroke (IS) patients undergoing carotid artery stenting (CAS).

Methods: In total, 124 consecutive IS patients were randomly allocated to the EA, TEAS, and sham groups (groups A, T, and S; 41, 42, and 41 cases, respectively) by software-derived random-number sequence. Groups A and T received EA and TEAS, respectively, at the Shuigou (GV 26) and Baihui (GV 20), Hegu (LI4) and Waiguan (TE 5) acupoints.

Intratumoral Hemorrhage as an Unusual Manifestation of Intracranial Subependymoma.

Background: Subependymoma is rare, and little is known about subependymoma with intratumoral hemorrhage.

Methods: A retrospective study of subependymoma was performed. Among 61 subependymomas, 4 cases of intratumoral hemorrhage were collected.

Sevoflurane neurotoxicity in neonatal rats is related to an increase in the GABA R α1/GABA R α2 ratio.

Exposure of neonatal rat to sevoflurane leads to neurodegeneration and deficits of spatial learning and memory in adulthood. However, the underlying mechanisms remain unclear. The type A γ-aminobutyric acid receptor (GABA R) is a target receptor for sevoflurane.
