MicroRNA(miRNA)is a small non-coding RNA that contains 21 to 23 nucleotides and can down-regulate gene expression by translational repression.Recent studies found that some miRNAs might function both as oncogenes and tumor suppressors;its role in the tumorigenesis may complement and enrich the mechanisms of tumorigenesis.Liver cancer is a great threat to human health,whose pathogenesis is still not completely understood.MiRNAs can influence the tumorigenesis,differ- entiation and treatment of liver cancer.Here we summarizes the related progression in research of miRNA and liver cancer.

Objective To investigate effects of ginkgo biloba extract(GBE) and tanshinoneⅡ A preventative administration against cerebral ischemia and reperfusion injury in gerbils.Methods Cerebral iscthemia and reperfu- sion injury were made by 10 minutes'occlusion of bilateral carotid arteries followed by 24 hours' reperfusion in ger- bils.GBE,tanshinone Ⅱ A,nimodipine or GBE plus tanshinone Ⅱ A were administrated intragastrically 3 days prior to and at the day of ischemia and reperfusion.Effects of experimental agents on mortality,stroke index,brain body index,water content in brain hemisphere,level of SOD activity and MDA in cerebral tissue were measured,and pathological changes of cortex and hippoearnpal CA1 sector were observed.Results GBE 48 mg/kg and tanshinone Ⅱ A 25mg/kg preventive administration could significantly reduce the stroke index,brain body index,and water in brain hemisphere,together with a reduced mortality of cerebral ischemia and reperfusion injuried gerbils.The two a- gents could also significantly improve the activity of SOD,reduce the level of MDA in cerebral tissue and the injury in cortex and hippocampal CA1 sector.Moreover,combined treatment of these two agents demonstrated more signifi- cant effects.Conclusion GBE,tanshinone Ⅱ A and combined therapy of these two agents may protect cerebral func- tion from ischemia and reperfusion injury through reducing the cerebral edema and attenuating the injury of oxygen free radicals.

Objective To investigate the effect of astilbin on expression of CTLA-4 in activated T cells of mouse heart transplantation model with acute rejection.Methods Cardiomyocytes of BALB/ c mouse and spleen cells of C57BL/6 mouse were separated.The cardiomyocytes(2?10~5/ml)as irri- tation cells and spleen cells(1?10~6/ml)as responsers were mixed and cultured.The model of mouse heart transplantation with acute rejection in vitro was established.Three groups were set up:control group,Astilbin(15/?g/ml) group,Astilbin+anti-CTLA-4 mAb 9H10 (30?g/ml)group.Apoptosis of T cells was observed by TUNEL.The expression of CTLA-4 in activated T cells was detected by RT-PCR and Western blot.Results Apoptosis indexes of activated T cells in Astilbin group were sig- nificantly higher than those in the control group(73.4%?12.5% vs 35.1%?9.2%,P＜0.01). The expression of CTLA-4 in Astilbin group was significantly higher than control group(P＜0.01), but there was no apparently difference between control group and Astilbin+CTLA-4 mAb group(P＞0.05).Conclusion Astilbin induces apoptosis of activated T cells in heart transplantation,which may be partially related to its enhanced expression of CTLA-4.

12.Meanwhile 10 healthy elderly subjects of similar age and gender ratio were matched as controls.There was no significant difference of age,gender,education,onset duration and MMSE.Attention task was carded out with silent color-word task:all participants pressed the left or right button to select the answer of congruence or incongruence when color nouns in red,green,blue or yellow ink appearing on the left part of screen and a target color appearing on the right part of the screen by.During the tasks,reaction time,false ratio,missing ratio and fMRI image acquisition was respectively recorded,which were later analyzed on SPSS 11.0 statistical parametric mapping software 2 (SPM2) respectively.Results The reaction time in dAD,AD and control group were (2214.4?1071),(2020.6?558.3) and (840.0?254.5) ms respectively.The false ratio were 8.3%,6.9% and 0.7% respectively,and the omit ratio were 3.6%, 2.9% and 0 respectively.Either AD with or without depression was slower than the controls in reaction time (P

The effects of an aqueous extract of Dracocephalum tanguticum Maxim. (DtM ) on p, b.b-1/ H. Hct. ESR. ESR-kand EPT of rats were studied by ip route. The animals were divided into three groups: normal pressure control group (NCG ). iowpressure treatment group (LTG )and lowpressure control group (LCG ). A11 p,b. Het. ESR-k increased stignificantly in rats exposed to stimulated altitude of 6500m for 10 days (8h/day),and the platelet and the ratio of left to ri1ght ventricle weights were obviously decreased in comparison with NPG. The above parameters of LTG .except Het.have noobvious difference as compared with NCG, Het in LTG increased obviously but lower than LCG. These results suggested that DtM may be used as an inhibitory agent against the changes of induced-hypoxia blood rheology, decreased platelet and hypertrophic right ventricle. In addition,the observation of tissue morphology showed that DtM possesses sometherapeutic effects to injuries of lung. liver and kidney of hypoxia rats.
