Genetic association of CHEK2, GSTP1, and ERCC1 with glioblastoma in the Han Chinese population.

Glioblastoma (GBM), a deadly brain tumor, is the most malignant glioma. It mainly occurs in adults and occurs significantly more in males than in females. We genotyped 19 tag single nucleotide polymorphisms (tSNPs) from 13 genes in a case-control study of the Han Chinese population to identify genetic factors contributing to the risk of GBM.

Protective effect of quercetin against oxidative stress and brain edema in an experimental rat model of subarachnoid hemorrhage.

Quercetin has been demonstrated to play an important role in altering the progression of ischemic brain injuries and neurodegenerative diseases by protecting against oxidative stress. The effects of quercetin on brain damage after subarachnoid hemorrhage (SAH), however, have not been investigated. This study was designed to explore the effects of quercetin on oxidative stress and brain edema after experimental SAH using four equal groups (n = 16) of adult male Sprague-Dawley (SD) rats, including a sham group, an SAH + vehicle group, an SAH + quercetin10 group, and an SAH + quercetin50 group.

[Stereotactic multi-target operation for patients with affective disorder].

Objective: To explore the efficacy and complication of bilateral multi-target radiofrequency lesion operation in patients with affective disorder.

Methods: One hundred and eighty-two cases with affective disorder were treated with unstaged bilateral multi-target radiofrequency thermocoagulation. The efficacy was evaluated with the method established in 1990 by the National Psychosurgery Cooperative Group.
