Risk factors and etiology for ischemic stroke in young adults / 国际脑血管病杂志

Ischemic stroke is a catastrophic event in young adults. It may cause death,disability, incapacity and decline in the quality of life. When the neurologists are facing the suspected ischemic stroke in young adults, the greatest challenge of diagnosis is to identify the causes. This article reviews the risk factors, etiological diagnosis as well as its associated disorders and dysfunction in young adults.

The protective effect of Vaccinium Bracteatum Thunb leaves and the extract against light injury of retina / 西安交通大学学报(医学版)

Objective To investigate the protective effect of the extract of Vaccinium Bracteatum Thunb(VBT) leaves against light injury of retina.Methods 20 Newzealand rabbits were divided into 4 groups: the normal control group,modelⅠgroup,modelⅡ group,and model Ⅲ group.The normal control group ate and drank freely.modelⅠgroup ate and drank freely but took in 50g/(kg?d) fresh VBT leaves daily for 4 weeks.model Ⅱgroup ate and drank freely,but took in 50g/(kg?d) old VBT leaves daily for 4 weeks.model Ⅲ group ate freely,but took in 50mg/(kg?d) extract of VBT leaves(resolved in water) daily for 4 weeks.All rabbits were exposed to strong light,meanwhile, the retinas were analyzed by electroretinogram(ERG) every week.Finally,all the rabbits were killed and the content of MDA and SOD in the retina were detected.Results In the control group,the latency time of the B wave increased and the amplitude of the B wave shortened,while in the model Ⅰ,Ⅱ and Ⅲ groups,the changes of B wave just opposite.The content of MDA in the model Ⅰ,Ⅱ,and Ⅲ groups was lower than that in the control group(P
