扫描

Our experimental research was composed of three parts including five experiments, all of which were aimed to explore whether and how the visual properties, as a pre-imaging factors, affected the processing of image, such as maintaining, scanning and rotating of image.

前三个实验主要验证视角大小是否对表象的短时保持和心理扫描、心理旋转等加工过程存在影响；实验四运用回归分析进一步探讨视角大小如何影响心理扫描这种表象加工过程；实验五探讨视角大小对不同难度的心理旋转任务的影响方式是否相同。

To investigate the effect of p38MAPK signal conducting pathway on livercancinoma cell's malignant phenotype induced by VEGF,we take theexperiment with cell growth test,scanning microscope and laser scanningconfocal microscope so that observe effect of p38MAPK signal conductingpathway on liver cancinoma cell growth,pseudopodium formation andframework of cytoskeleton induced by VEGF.results indicate that the cellbecame ellipse and there were more and thick pseudopodium in the cell'ssurface after being treated by VEGF,and destroyed framework ofcytoskeleton,which can be blocked by pretreated with a special inhibitor ofp38MAPK SB203580 so that VEGF promote metastasis by enhancing livercell migration and movement via p38MAPK signal conducting pathway,butVEGF promote cell growth without p38MAPK signal conducting pathway.

为进一步探讨VEGF通过p38信号传导通路诱导肝癌细胞转移时，对肝癌细胞恶性表型的影响，采用细胞增殖实验、扫描电子显微镜、激光扫描共聚焦显微镜观察VEGF对肝癌细胞增殖作用、细胞伪足形成、细胞骨架微丝结构的影响以及p38MAPK信号通路调控作用。结果显示，VEGF能够不通过p38信号通路促进肝癌细胞增殖；VEGF诱导肝癌细胞丝状伪足增多、增长，使细胞骨架微丝结构破坏、甚至消失。阻断p38MAPK信号通路，可以抑制VEGF诱导的肝癌细胞伪足形成，细胞骨架丝状结构呈束状，排列较规整。上述结果表明，VEGF可以通过p38信号传导通路诱导肝癌细胞伪足增多、增长，促使细胞骨架微丝结构破坏，使肝癌细胞迁移、运动能力增加，促进肿瘤转移。VEGF并不通过p38信号通路诱导肝癌细胞增殖作用。
