Vinpocetine improves dyskinesia in Parkinson's disease rats by reducing oxidative stress and activating the Wnt/β-catenin signaling pathway.

Parkinson's disease (PD) is the commonest neurodegenerative disorder. It reduces motor and cognitive function in patients. Vinpocetine (Vinp) has the effects of anti-inflammatory and antioxidant, and could improve cognitive function in patients.

[Correlates of cognitive impairment in patients with leukoaraiosis by magnetic resonance spectroscopy].

Objective: To explore the pathological changes in patients with leukoaraiosis (LA) by magnetic resonance spectroscopy (MRS) and examine its relationship with cognitive function.

Methods: Twenty-three LA patients and 23 age and gender-matched healthy subjects were recruited from the Department of Neurology, Beijing Chaoyang Hospital, Capital Medical University between August 2010 and November 2010. All participants underwent the neuropsychological tests.

Genetic variants on chromosome 9p21 and ischemic stroke in Chinese.

In a hospital based case control study, we investigated the association of cyclin-dependent kinase inhibitor 2A (CDKN2A) gene, cyclin-dependent kinase inhibitor 2B (CDKN2B) gene, and two genetic variants (rs10757274 and rs2383206) on chromosome region 9p21 with ischemic stroke in Chinese Hans. Two polymorphisms in the CDKN2A gene (rs3088440 and rs3731245) and two polymorphisms in the CDKN2B gene (rs3217992 and rs1063192) were selected by using a strategy of tagging single nucleotide polymorphisms (tSNP). We observed significant association of rs2383206 with ischemic stroke.
