[Clinical features and scalp video electroencephalogram analysis of patients with insular epilepsy].

Objective: To explore the clinical and scalp video electroencephalographic(EEG) characteristics of insula lobe epilepsy identified by intracranial electrode, and to provide some references for early diagnosis and clinical evaluation in patients with insula lobe epilepsy. Methods: A total of 12 patients diagnosed with insula lobe epilepsy identified by intracranial electrode were included from Xuanwu Hospital of Capital Medical University from January 2013 to December 2015.Their clinical and EEG data were analyzed. Results: 91.7% of patients had sensory aura before seizure, and had clear consciousness at onset initial time.Visceral motor and visceral sensation were the most common symptoms, and the epilepsy was always ended with somatic movement.There was no prominent characteristic changes in scalp EEG. Conclusions: Clinical features are important for insula lobe epilepsy diagnosis.When patients present symtoms aforementioned, insula lobe epilepsy should be considered.

[Effect of aloe-emodin on c-myc gene expression of cultured vascular smooth muscle cells of injured artery].

OBJECTIVE: To study the molecular mechanism of aloe-emodin (AE) in inhibiting smooth muscle cells' (SMC) proliferation. METHODS: Deendothelialization was performed in abdominal aorta of Japanese white ear rabbits by using 3F Fogarty arterial embolectomy catheter. The media of abdominal aorta was isolated 48 hrs later for performing primary SMC culture. Cells were synchronized with G0/G1 phase by serum starvation, the AE was then added to the culture medium of experimental group, at a concentration of 20 micrograms/ml, and to the control group, equal volume of culture solution was added instead. The c-myc mRNA and protein expressions were examined 3 hrs later by using techniques of Northern blotting, Western blotting and immunocytochemistry respectively. RESULTS: In comparing with the control group, neither the expression of c-myc mRNA nor the expression of c-myc protein was changed after addition of AE. CONCLUSION: The inhibition of AE on SMC might not be due to influencing c-myc expression, but via other pathway.
