ABSTRACT
Objective To explore the effect of levetiracetam(LEV)on cognitive function and quality of life of patients with partial seizure.Methods There were two phase for this study.Phase one was a randomized,double-blind,placebo-controlled study for 16 weeks.Phase two was an open label period for 24 weeks.Medicated patients underwent test on the cognitive function and Health Related Quality of Life (HRQOL)at the baseline respectively at the end of 16 weeks and at the end of 40 weeks.Results(1) Compared the result at the end of 16 weeks with the baseline,LEV group used less time to do Wisconsin card sorting test(WCST,reduce scores -110.3),delayed logical memory were improved(reduce scores 3.4,P
ABSTRACT
Objective To reverse P-glycoprotein-mediated muhiple drug resistance using RNA interference(RNAi)in cultured rat astrocytes.Methods Astroeytes overexpressing P-glyeoprotein induced by coriaria lactone were transfected with the short-hairpin RNA expression vector-p-SIREN shuttle designed to target Mdrl mRNA.The mRNA level of Mdrl gene was evaluated by real-time PCR;the P-glycoprotein was examined by immunocytochemistry and image analysis,meanwhile the rhodamine efflux was assessed by flow cytometry.Results The astrocyte model overexpressing P-glycoprotein were established and successfully transfected with the short-hairpin RNA expression vector-p-SIREN shuttle.The mRNA level of Mdrl gene was knocked down by 67.70%(P
