Alzheimer's disease (AD) is a neurodegenerative disorder characterized by memory loss and cognitive decline. The pathological eatures of Alzheimer's disease are abnormal deposition of amyloid beta-peptides (Aβ), neurofibrillary tangles, cholinergic deficits, and loss of synaptic processes and dendritic spines. Senescence accelerated mouse prone 8 exhibits age-related deficits of learning and memory from an early age, tau protein phosphorylation, neurotransmitter changes, synaptic structure and function disorders, circadian rhythm disorders,as well as gene expression and many other characteristic changes, which are consistent with Alzheimer's disease pathological changes，and can be used as an ideal animal model for Alzheimer's disease prevention drugs development.

ObjectiveTo observe the easing pain effect of being used Guishen Pain-Killer, a Chinese medicine, for improving the anaesthesia project which was used in using micro-wave heating among tissue to treat hemorrhoid.MethodsOn the basic of the original anaesthesia project, patients drunk the Chinese medicine Guishen Pain-Killer 50ml which was heated to 40℃ by microwave stove for pre-anaesthesia drug 10 minutes before the operation. The effect of adding drinking Guishen Pain-Killer and of merely using the original anaesthesia project were estimated with the McGill Questionnaire and stated the data with u test.ResultsThe pain estimation of those patients who drunk Guishen Pain-Killer before operation was (1.71±1.05) and (1.32±0.83), in operation and just after operation,while that of patients who didn't drink Guishen Pain-Killer before operation was (2.58±1.03) and (1.93±1.11),P<0.01.ConclusionGuishen Pain-Killer can be used as the pre-anaesthesia drug in micro-wave heating among tissue to treat hemorrhoids.

Objective To evaluate the effects of exogenous adenovirus-mediated gene transfer of human apM1 gene (Ad-apM1) on malonaldehyde (MAD) and superoxide dismutase (SOD) levels in human umbilical vein endothelial cells (HUVEC). Methods HUVEC proliferation was measured by MTT after infection by AdapM1. Adiponetin protein level in cell culture medium of HUVEC cells infected with Ad-apM1 was detected by double antibody sandwich ELISA. The levels of MAD and SOD were measured by chromatometry. Results MTT assay showed that Ad-apMl had no effect on HUVEC proliferation. Human adiponectin protein levels in cell culture medium significantly increased after HUVEC was infected with Ad-apM1 for 24, 48, and 72 h, along with decreased MAD and increased SOD ( all P<0.05 ). MAD levels markedly increased and SOD levels decreased after HUVEC were incubated with 100 μmol/L H2O2 for 6, 12, and 24 h, and these reactions were reversed by AdapM1 transfection (all P<0.05 ). Conclusions HUVEC infected with Ad-apM1 effectively secrete human adiponectin. Ad-apM1 exerts antioxidation effect and antagonizes H2O2 -induced endothelial injury.

Objective To compare the results of three kinds of heart preservative fluids,namely histidine-tryptophan-ketoglutarate(HTK)solution,Fuwai modified solution(FWM)and St.Thomas' Hospital cardioplegic solution number 2(St.Thomas-Ⅱ)for the preservation of isolated rat hearts under low temperature.Methods Fifty-four male SD rats were randomly divided into HTK,FWM and ST-Ⅱ groups(18 each),and each group was divided into three subgroups(6 each)according to different duration of preservation under low temperature(4,6 and 8 hours).The hearts were harvested and then mounted on the Langendorff apparatus and perfused with K-H buffer solution for determination of the baseline hemodynamic values(HR,LVSP,?dp/dtmax and CF).The isolated hearts were then arrested and stored in different preservative solution as mentioned at 4℃ for 4,6 or 8 hours.The hemodynamic values were measured before cardiac arrest and after cardiac reperfusion in Langendoff model,and the recovery rates of the values were calculated.The hearts were finally sectioned after reperfusion for the observation of morphological changes with light microscope.Results With the same hypothermic preservation time,the recovery rates of hemodynamic values were significantly higher,and the changes in myocardial structures were obviously less in HTK and FWM groups than in ST-Ⅱ group(P0.05).Conclusions HTK and FWM solutions are more effective than St.Thomas-Ⅱsolution in preservation of isolated heart under low temperature with the same storage duration.The effect of HTK solution for preservation of isolated heart descended with the prolongation of preservation time,especially so after 8 hours.

Objective To explore the value of temporary cardiac pacemaker therapy on children with Adam-Stoke syndrome(ASS).Methods Nine children with ASS was implanted the emporary cardiac pacemaker under X-ray or blinding inserted beside bed.Results Seven children was successfully implanted the temporary cardiac pacemaker within 1-2 d of ASS attack,and two children was successfully implanted at 10 d and 20 d after ASS attack, respectively. Five patients was cured, two children was died, and two children was implanted the permanent cardiac pacemaker. During pacing, two patients had the electrode shifted,and one patient had the cardiac murmur,and one patient had the local skin infected.Conclusion Temporary cardiac pacemaker can successfully treat children with ASS attack;the earlier the implantation,the better the prognosis.

Objective:To study the clinical efficacy of acupuncture for ischemic stroke and its effect on ET-1 levels in IS cases.Method:The 63 cases were randomized into a treatment group (31 cases),receiving acupuncture and routine method,and control group (32 cases),receiving routine method alone.Seven days constitute a course of treatment,a 2-day interval between two courses.The clinical efficacy and ET-1 level in two groups were compared after four weeks.Result:The total effective rate in the treatment group and control group were 96.8% and 75% respectively,with a statistical significance (P＜0.05);the ET-1 level in blood plasma also with a statistical significance after the treatment (P＜0.05);the pre-treatment and post-treatment ET-1 level in the treatment group showed a statistical significance (P＜0.01),whereas the control group didn't.Conclusion:Acupuncture is effective for ischemic stroke and can lower the ET-1 level in ischemic stroke cases.

[Objective]To evaluate the incidence of chromosomal abnormalities and associated abnormalities in prenatally diag?nosed clubfoot,and to determine the prognostic factors as well.[Methods]A total of 89 fetuses with clubfoot diagnosed during Janu?ary 2010 to October 2015 in prenatal ultrasound scan and confirmed postnatally or by autopsy,were selected,within which 16 (18.0%)cases were without other abnormalities and 73(82.0%)cases were with other abnormalities. The associated abnormalities were identified ,the correlation with chromosomal abnormalities were analyzed with Fisher analysis and the factors affecting the outcomes were determined with Logistic regression analysis.[Results]Among associated abnormalities ,the skeletal abnormalities besides the clubfoot were the most frequently associated anomalies (35 ,47.9%),and the central nervous abnormalities followed secondly(30,41.1%). A chromosomal abnormality,with trisomy 18 being the most frequently detected,was identified in 34%(17/49)of the clubfoot fetuses with other anomalies ,whereas none of chromosomal abnormality was identified in 11 fetuses without other anomalies,a significant different rate of aberrant chromosome noted(P < 0.001). The survival rate of clubfoot fetuses without other anomalies was higher than that of clubfoot fetuses with other anomalies(50.0%vs 1.3%,P=0.03). The conditions of with or without associated anomalies were the independent prognostic factors (P = 0.01),the clubfoot fetuses associated with other anomalies had poor outcomes[OR=11.9(95%CI:1.8,80.1)].[Conclusion]Skeletal abnormalities besides the clubfoot were the most frequently associated anomalies. The condition of with or without associated anomalies is the independent prognostic index for fetuses with clubfoot. Aneuploidy were more commonly in clubfoot fetuses with associated abnormalities than in those without other abnormalities. No indication for karyotyping suggests for the clubfoot fetuses without other abnormalities due to the low incidence of associate chromo?somal anomalies.
