Methods The Epidermal stem cell were isolated by adhering to collagen type IV after obtained by digesting human foreskin with Dispase Ⅱ and Tryp and culture in vitro in K-SFM. The expressions of β1-integrin and keratin 19 (K19) in epidermal stem cell were detected with immunocytochemical methods,and the colony forming efficiency was also studied .

At the super-low permeable reservior sandstone of Fu and Yang in Daqing Oilfield, many pore throats exist a lot in the types of compacted and restored flakes and curved lamellas while the pore volume of micropore and the thin, compacted and shrunken throat that contribute little to flow take large scale in the total pore space. Thereof high filtrational resistance is caused by much trouble including high content of reservoir shale, serious sensibility to pressure at waterflooding, remarkable effects of undersaturation and water blocks in micropore. A method with laboratory experiment, theoretical confirmation and field application included was adopted to analyze the non-linear flow characteristics, to reveal the deep mechanism of pinhole enveloping macropore and to provide a new technology of improving the development effect. The outcomes aquired are as follows: Multiple cores with different low and super-low permeability were selected to perform seepage experiments by gas, water and oil. Three fields of flow were observed in the reservoir at different low and super-low core permeability. They are pseudo- elastic flow, transition flow and plastic creep flow. So the concept that there was no correlation of rocky absolute permeability with fluid properties that pasted itself was broken up. Two-phase seepage of water displacing oil in uniform super-low permeability shows that the two-phase seepage zone is narrow.

针对大庆油田扶、杨特低渗透油层砂岩孔隙喉道的大小和形态以压实再生型片状、弯片状喉道分布较广，压实、缩小型细喉道型，微孔不可流动的孔隙体积所占总孔隙体积的比例较大的特点；及储层泥质含量高，注水开发中压力敏感性强、微孔隙欠饱和及水锁效应显著，导致流体渗流阻力增大的问题，本文采用室内实验、理论推证和矿场应用相结合的方法，研究、分析了流体非线性渗流特征，更深刻地揭示出小孔包围大孔的机理及产生原因，并提供了改善开发效果的新的技术方法，取得如下成果：选择不同渗透率的低渗透、特低渗透岩心，进行了气、水和油单相渗流实验，揭示出当岩心渗透率不同时，油层内的流体呈现出拟弹性流变、过渡流变、塑性蠕变三种流变区，从而打破了岩心的绝对渗透率与通过岩心流体性质无关的观点；同类特低渗透岩心的水驱油两相渗流实验表明，两相渗流区较窄。

The woman protection occupied the main cases; the children protection was at the second group. We shall also watch the victims of children, teens, old ages; thoughs the percentages are lower. These three groups belong to the weakish parts of society, though they under the umbrella of the law of domestic violence prevention still.

暴力种类仍以妇女保护为主，儿童少年保护居次，其中需正视之问题为儿童、少年及老年虽然所占之比率较低，但这三者系属社会的弱势族群，社会层出不穷发生老人弃养及青少年儿童虐待事件，但在家庭暴力防治之保护伞下，该族群仍是弱势之一方，这与此两种年龄层谁去举发？
