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.

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.

Objective: Determining the content of five flavonoids in Artemisia frigida by high performance capillary electrophoresis (HPCE) method to provide reference data for the evaluation of processing products of A. frigida. Methods: Treated by different processing technologies, the content of five flavonoids compounds can be determined and compared by HPCE. Results: Regression equations were 5,7,3′-triterhydroxy-4′-methoxyflavone Y = 0.114 3 X + 0.032 7, r = 0.999 8; 5,3′-dihydroxy-6,7,4′-tritermethoxyflavone Y = 0.100 9 X + 0.048 5, r = 0.999 6; quercetin Y = 0.055 5 X + 0.026 8, r = 0.999 6; 5,7,3′-triterhydroxy-6,4′-dimethoxyflavone Y= 0.113 2X-0.016 1, r = 0.999 3; luteolin Y = 0.097 9X-0.029 5, r = 0.999 4. Five kinds of flavonoids were good linear relationship at 1.00-40.00, 10.00-200.00, 5.00-100.00, 1.00-40.00, 1.00-40.00 μg/mL. The average recoveries were 98.44%, 97.75%, 97.73%, 97.98%, and 98.07%. And RSD were 1.60%, 1.03%, 1.57%, 0.94%, and 1.20%. Conclusion: The results reveal that the different processing technologies have different effects on the content determination of five flavonoids compounds in A. frigida. Using the five flavonoids as testing indexes, the best processing technology of A. frigida is heating and drying to constant weight at 60 °C.

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.
