Objective To investigate G protein-coupled estrogen receptor(GPER)mediated neuroprotective effect and mechanism in an ischemic stroke model. Methods Bilateral ovariectomy (OVX)was used to establish a castrated model of adult SPF grade female SD rats. Enzyme-linked immunosorbent assay was used to detect serum estrogen level at 4 weeks after procedure.Middle cerebral artery occlusion(MCAO)was use to prepare a stroke model.The rats were randomly divided into sham operation(n=6),MCAO(n=7),MCAO+estrogen(MCAO+E2,n=8),MCAO+agonist(MCAO+G1,n=8)and MCAO +antagonist G15(MCAO +G15,n =7)groups. The neurological severity score (NSS),2,3,5-triphenyltetrazolium chloride(TTC)staining were used to measure the volume of cerebral infarction in order to assess the effects of different interventions.Western blot was used to detect the protein expression of hypoxia inducible factor-1α(HIF-1α),c-Jun N-terminal kinase(JNK),and Caspase-3 in the ischemic penumbra. Results (1)Estrogen level:after OVX,The level of serum estrogen in rats was significantly lower than that before castration(20 ± 9 ng/L vs. 73 ± 21 ng/L,P <0. 01).(2)NSS score:the NSS score of MCAO in each group was significant higher than that in the sham operation group (P<0.01);The NSS score of the MCAO+G1 group was significantly lower than that of the MCAO group and the MCAO+G15 group(6.0 ±1.8 vs.11.9 ±2.0 and 10.0 ±2.1).The difference was statistically significant (all P<0.05).(3)Cerebral infarct volume:there was significant difference in infarcted volume between the sham operation group and all other groups(all P<0.01);Compared with the MCAO group and the MCAO+G15 group,the infarct volume of the MCAO+E2 group and MCAO+G1 group was significantly reduced(19.8 ± 4.0%,14.0 ± 2.9%)vs.29.7 ± 5.8% and 27.6 ± 3.6%).The difference was statistically significant (all P<0.05).(4)Results of Western blot:the relative optical density values of HIF-1α,JNK,and Caspase-3 of the MCAO group were higher than those of the MCAO + G1 group(all P <0.01). Conclusions GPER mediates the neuroprotective effect of estrogen in the ischemic stroke model.This protective effect is associated with the regulation of the expression levels of HIF-1α,JNK,and Caspase-3.

Objective To assess the psychometric potential of the Montreal Cognitive Assessment Scale-Beijing (MoCA-BJ) as a screening instrument for mild cognitive impairment (MCI) in older adults in Wuhan communities of central China. Methods MoCA-BJ and Mini-Mental State Examination (MMSE) were adopted to assess the MCI of 381 older adults from 13 communities in Wuhan in 2015. Confirmatory factor analysis was conducted to evaluate the construct validity of MoCA-BJ, and the relationship between all aspects of cognitive function and MoCA different dimensions. Results MoCA-BJ had acceptable reliability (w=0.76), and MoCA-BJ and MMSE estimation results were highly correlated (r=0.73, P<0.01). By comparing three measurement models through confirmatory factor analysis, we found that the MoCA-BJ scale had two factors (F1: visual space executive function, F2: memory-based other cognitive functions) in model 3, fit degree of which was higher than model 1 by one factor, and there was a statistically significant difference in the number of factors between model 1 and model 3 (χ2dif=8.73,P<0.01). Conclusions The MoCA-BJ has two underlying factors that respectively represent two highly correlated but distinct factors, cognition and visual-spatial. Uninformative items should be revised with culturally sensitive items and the cut-off point for mild impairment should also be altered.
