Functional properties of silk fibroin were measured. The results showed that its emulsion capacity and emulsion stability were good at wide pH range from 3 to 10.Sodium chloride decreased EC and ES to some extent. EC and ES improved as the concentration of silk fibroin increased, until reaching its critical micelle concentration 0.5%. Foam capacity of fibroin was lower than that of caseinate, while its foam stability was markedly better than that of caseinate.

对丝素的功能性质进行了研究，结果表明，丝素在pH3～10范围内具有较好的乳化能力和优良的乳化稳定性；氯化钠的添加使丝素乳化能力和乳化稳定性略微下降；随着丝素浓度增加，丝素乳化能力和乳化稳定性均提高，当丝素浓度高于丝素临界胶束浓度0.5％时，乳化能力增幅变缓。

复合纳米纤维长丝束制备装置及其制备方法是一种简单、高效电纺制备纳米纤维长丝束的方法，其步骤为将料液输送给支架(3)上的电纺喷头对(1)；喷口相向的电纺喷头对(1)的每个喷头分别施加相反极性的直流高电压；每对相向喷口喷出分别带相反电荷的纳米纤维，并在空中相互吸引、碰撞形成复合纳米纤维，经牵引、拉伸后形成复合纳米纤维长丝束；第一对相向放置的电纺喷头纺丝形成的复合纳米纤维长丝束向下拉伸，并作为接受体与第二对电纺喷头喷出的分别带相反电荷并相互吸引的纳米纤维在空中相遇，被第二对电纺喷头喷出的纳米纤维包裹，经牵引、拉伸后形成两层复合纳米纤维长丝束；依次类推，最后经导丝辊对(2)牵引、拉伸后得到多层复合纳米纤维长丝束。

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。

一般而言，长纤维是指纤维之长度/厚度之比率大于10%者称之。而在化学纤维当中，所有可纺丝之原料，皆可制成长纤维。长纤维因其每束丝中各单纤维根数与细度又可分为复丝与单丝，通常用于衣着类长纤维大都为复丝，而单丝则大都在非衣着用途，如钓鱼线等，其单纤维直径为60μ以上，甚至可达5 mm。

The morphology and structure of reconstructed tissue was detected by microscope and scanning electron microscope.Results:(1) Compared with the control group, the cellular proportion of laminin group increased in 62 ~M phase, and decreased in Go~Gi phase significantly. As shown by the microscope, the cells of control group were in low density. The cells in mass connected tightly. The microfilament appeared reticular formation. The nucleus were the same in size. The cells of laminin group were in high density and put out so many lamellipodia, filopodia, which connected with the surrounding cells. The microfilament increased, elongated, and changed from reticulodromous to sarciniform, which reached to the pseudopods. The nucleus were different in size .(2) As shown by the inverted microscope and the cell growth curve, comparing with the controlgroup, cells of each test group increased evidently. The cellular proportion of each test group increased in S phase and G2 ~M phase, and decreased in Go~Gi phase significantly, but there was no considerable interations between LN and EGF;(3) As shown by the morphological observations, the cultured cat corneal endothelial cells formed an integrated membrane, and attached to the Descemets membrane closely, which was similar to the natural tissue. The cells connected tightly to each other, and some of them arranged in hexagon approximately.

结果：(1)层粘连蛋白组处于G_2～M期细胞比例较对照组显著提高，Go～G_1期细胞比例显著下降，提示层粘连蛋白促进内皮细胞DNA合成，及细胞分裂增殖；光镜下，对照组细胞分布成团状，细胞密度较低，细胞间连接紧密，细胞内微丝结成网状，细胞核大小一致；与对照组相比，层粘连蛋白组细胞生长旺盛，细胞密度高，向周边伸出大量板状及丝状伪足，细胞内微丝增多、拉长、集结成束，伸入伪足中，细胞核形状大小不一致；(2)倒置显微镜观察及细胞生长曲线显示，各组细胞数目随时间增加而明显增多，各实验组较对照组增生显著，EGF和LN联合应用组各时间点细胞数目最高；实验组处于S期和G_2～M期细胞数目增加，Go～G_1期细胞数目减少；提示EGF、LN单独及联合应用均可促进细胞增殖，但尚不能认为二者有交互作用；(3)倒置显微镜下，组织培养的猫角膜内皮细胞排列成密集的单层，细胞间连接紧密；组织学观察发现，培养的猫角膜内皮细胞形成完整的内皮层，贴附于脱水基质的后弹力膜上，与正常的角膜内皮组织结构相似；扫描电镜下，组织培养的猫角膜内皮细胞间紧密镶嵌排列，可见某些细胞呈近似六边形排列，细胞大小不甚一致，胞核清晰。
