High-frequency Oscillations and the Seizure Onset Zones in Neocortical Epilepsy.

Background: To study the characters of high-frequency oscillations (HFOs) in the seizure onset zones (SOZ) and the nonseizure onset zones (NSOZ) in the electrocorticography (ECoG) of patients with neocortical epilepsy.

Methods: Only patients with neocortical epilepsy who were seizure-free after surgery as determined with ECoG were included. We selected patients with normal magnetic resonance imaging before surgery in order to avoid the influence of HFOs by other lesions.

[Effects of electroacupuncture on the expression of nestin in endogenous neural stem cell in hippocampus in rats with focal cerebral ischemia-reperfusion].

Objective: To explore the mechanism of electroacupuncture for treating focal cerebral ischemia-reperfusion injury.

Methods: Seventy-five Wistar rats were randomly divided into a control group, a model group and an electroacupuncture group, 25 cases in each group. The model of focal cerebral ischemia-reperfusion was established by inserting nylon thread into the internal carotid artery except the control group which was only separated of the carotid artery without occlusion.

Effects of acupuncturing Tsusanli (ST36) on expression of nitric oxide synthase in hypothalamus and adrenal gland in rats with cold stress ulcer.

Aim: To study the protective effect of acupuncturing Tsusanli (S(T)36) on cold stress ulcer, and the expression of nitric oxide synthase (NOS) in hypothalamus and adrenal gland.

Methods: Ulcer index in rats and RT-PCR were used to study the protective effect of acupuncture on cold stress ulcer, and the expression of NOS in hypothalamus and adrenal gland. Images were analyzed with semi-quantitative method.
