Based on a lot of experiments, it shows the distinct error between classical theory curve which express the relation of cell diameter, cell density and foam tensile strength , tensibility tensile product and re-spring degree and experiment curve. It also can＇t explain the relation of hole degree , area of cell wall with above four mechanics parameter. But the sub-cluster scale theory was demonstrated successfully to explain the relation of cell structure and foam mechanics property on different mold temperature, mold pressure, mold period and different chemical blowing agent, blowing activator content.

通过大量的实验结果理论分析表明：以往的经典理论存在着很多不足之处，它不能有效地解释孔径、泡孔密度与抗拉强度、断裂伸长率、断裂功、及回弹率之间的理论曲线与实验曲线之间的偏差，也不能解释空隙度、泡孔壁厚与上面四者之间的关系，而群子标度理论则成功地论证了在不同模压温度、模压压力、模压时间及不同用量发泡剂、发泡促进剂条件下泡体力学性能与结构之间的相关性。

In this thesis, we find that dlg is indispensible in the establishment of anterior-posterior and dorsal-ventral polarity of drosophila oocyte. Removal of Dlg function from the posterior follicle cells using the FLP/FRT system leads to disruption of oocyte skeleton reconstruction that is elicited by the failure of those posterior cells to differentiate normally in mid-oogenesis. We demonstrate that abnormity of Notch, JAK-STAT and EGFR signal pathway in dlg mutants contributes to this aberrant differentiation. dlg null mutant also blocks the normal differentiation of two groups of anterior follicle cell-stretched cell and centripetal cell, but not border cell, with a lower penetrance. However unlike the result in posterior follicle cells, Notch and JAK-STAT signaling are both undisrupted in all mutant anterior follicle cells, implying other fate determinants may be involved.

我们的研究发现，后端滤泡细胞中的Dlg在果蝇卵子发生中期卵母细胞前后轴和背腹轴建立过程中也是必须的，PFC中dlg完全缺失型突变引起PFC的分化异常，导致卵子发生中期卵母细胞骨架重组异常，Stau、Grk等极性决定蛋白定位错误。dlg突变阻碍了Notch、JAK-STAT、EGFR等调节PFC分化的信号通路的激活。dlg突变的PFC也没有获得前端滤泡细胞命运。dlg突变不影响前端滤泡细胞群中边界细胞的分化，但是在一定程度上影响伸展细胞和向心细胞的分化，并且这种影响不依赖于前端滤泡细胞Notch或JAK-STAT信号激活的异常。

2.3 体外NKG2D结合实验和细胞因子分泌实验间接ELISA检测结果显示：原核表达复性后的ULBP4能与人NKG2D结合，而带His标签的无关蛋白则不能与之结合，说明复性后的ULBP4仍能维持正确的天然构像。

Results Using different concentrations of 5fluorouracil to deal with A549 cells, with the increase in drug concentration and treatment time,cell survival rate decreased significantly;and low concentration of 5fluorouracil induced the cell spread and increased vacuolization within the cytoplasm, acridine orange staining showed an increase in acidic vesicles,high concentration made the cell round and cell apoptosis.

RESULTS:Our results indicate that the chemokine CCL5 can induce migration in humanbreast carcinoma cell line MCF-7 in vitro and suggest a potential role for Ezrin in theprocesses of breast cancer cell migration,invasion and possibly metastasis responsed toCCL5.We demonstrate that Ezrin siRNA specifically inhibits Ezrin expression of MCF-7cells and deregulates several functions such as cell motility and cell invasion,indicatingthat Ezrin plays a key role in the development of human breast cancer cells.It\'s suggestedthat Ezrin may act as a new anti-invasion therapeutic target for human breast cancer.
