Fibrillar collagen(Collagen typeⅠand Ⅲ) in sinusoids of normal liver was successfully observed through second harmonic generation microscopy.

分别用前向二次谐波及背向双光子荧光对肝脏标本的成纤维胶原和肝细胞浆进行成像，将结果与传统的Masson's三染色法进行比较。

The management under the modernity make the chair in university become a quantitative posatition,the posation generate power through symbol,the formulable academic posation generate strong discipline power.Academic creation become a plan project,individuals face a giant engineering structure,the individual moral sensitivity ebbed away. Bestir excessively make arousal become chastisement.Academic activity is making difference and competition in the control of currency, and academic activity become monetization. Academic estimation become a shortterm action.

现代性之下大学的管理使得大学的学术职位演变为一个数量化的位置，这一位置利用符号产生力量，&公式化&的学术位置制造了强大的规训力量；学术创造变成规划性工程，个人时刻面临着非个人的巨型工程结构，个体的道德敏感性泯灭其中；激励与惩罚在现代性之下分界线模糊，对学术激励的过分使用使学术激励其演化成了学术惩罚；大学内学术在货币指挥下正不断地制造差异与竞争，学术货币化；学术考核则演变成一种短期行为。

The batch seeded isothermal desupersaturation experiments of SPM in aqueous solution were carried out and the overall crystal growth kinetics parameters were determined by the nonlinear optimization techniques. Assuming that the volume diffusion rate at growth is equal to the mass transfer rate at dissolution under the same conditions, the two-step crystal growth rate parameters can be determined. At the fow supersaturation, the surface integration rate is proportional to relative surface supersaturation.

通过测量螺旋霉素均相成核动力学，获得了表面能的值，估算出表面熵因子的值在1.41～1.56之间，从而可以推断出螺旋霉素晶体生长的表面反应速率同表面相对过饱和度成线性关系，这种生长机理同第四章得到的结果是相吻合的；利用估算的表面熵因子的值，把螺旋霉素晶体看作为简单的立方科瑟尔晶体，根据能量最低原理，对螺旋霉素的晶体生长进行了模拟。

OBJECTIVE: To compare the differences of gene expression and the response to bFGF of human umbilical cord CD34+ and CD133+ cells, and to explore gene expression changes of bFGF-induced umbilical cord CD34+ and CD133+ hematopotic stem cells/hemapoietic progenitor cells in vitro.

目的：利用基因芯片比较脐血CD34+和CD133+细胞基因表达的差异，并探讨碱性成纤维细胞生长因子体外诱导脐血CD34+和CD133+造血干/祖细胞分化的基因表达变化，及其对碱性成纤维细胞生长因子反应性差异。

Fibroblasts have the ability to secret many kinds of extracellular matrix and cytokines relevant to hepatogenic differentiation. So, we investigate whether coculture of hADSCs with fibroblasts without cell-cell contact play a role in hepatic differentiation of hADSCs by RT-PCR analysis of hepatic specific gene expression and real-time PCR analysis of Alb expression.

成纤维细胞能够分泌很多利于干细胞向肝细胞分化的细胞外基质和细胞因子，我们采用非接触共培养的方式对成纤维细胞与人脂肪干细胞共培养能否引发其向肝细胞的分化进行了研究。

The heterogonous nucleation of nano - CaCO3, PP - g - MA and PP - g - AA increases the crystallization temperature and melting point of PP.

纳米CaCO3和增容剂对PP／PS共混物中PP结晶存在异相成核作用，提高PP结晶温度和熔点，PP—g—MA和PP—g—AA的异相成核作用比CaCO3的大。

Diffusion tensor imaging is a kind of new technique after diffusion weighted imaging.DTI can reflect anisotropy hydrone molecular diffusion features of damaged myeloid tissue through measuring apparent diffusion coefficient and fractional anisotropy.Accordingly,we can make more precise and allround estimate about spinal compression on microscopic scale.

磁共振扩散张量成像是继扩散加权成像后发展起来的一种新技术，它通过测量表观扩散系数及部分各向异性值来反映损伤脊髓组织的各向异性水分子扩散特征，从而在微观水平对脊髓压迫症做出更精确和全面的评价。

Detect that whether the ADSCs were differentiated inducedly into osteoblasts or adipogenic cells by Alkaline phosphatase staining、Von kossa staining and Oil red "O"staining after the ADSCs were cultured in inductive basic medium containing osteogenic induction agent and adipogenic inducers for four weeks.②.

①。采用密度梯度离心法加贴壁培养法对兔脂肪组织进行了分离纯化，CD44免疫组化法分析ADSCs表面标志；用含成骨、成脂诱导培养基培养4周后，行碱性磷酸酶染色、Von kossa染色及油红&O&染色检查ADSCs是否向成骨、成脂细胞定向分化。②。

In this study, poly (PA12T), poly (PA12I) and PA(12T-co -121) were synthesized using terephthalic acid, isophthalic acid with dodecamethylene diamines.
