Objective To explore an experimental method of transfecting the marrow stromal stem cells with the reconstructed PGL3-transforming growth factor-β1 （TGF-β1） gene and to evaluate the feasibility of self-induction of MSCs to the chondrocytes in vitro so as to provide a scientific and experimental basis for a further ＂gene enhanced tissue engineering＂ research.

目的 探讨将编码细胞转化生长因子β1（transforming growth factorβ1，TGF—β1）的重组PGL3-TGF-β1质粒转染兔骨髓基质干细胞（marrow stromal stemceils，MSCs），体外通过自分泌、诱导作用向软骨细胞方向分化的可行性，为基因加强组织工程学修复软骨损伤提供体外实验依据。

Methods This study consisted of 36 male Wistar rats. A rat model of intestinal adhesions was done as follows: serous membrane of the caecum was scuffed, its raw surface was dropped with absolute alcohol, the mesentric artery of the caecum was then clamped. The rats were divided into three groups. PSS, sodium hyaluronate or normal saline was applied to the scraped cecum before closing the abdomen.

选用雌性Wistar大鼠36只，刮伤其盲肠浆膜，创面滴无水乙醇，钳夹盲肠系膜动脉制造大鼠肠粘连的动物模型，随机将动物分成3组，分别在关腹前于创面涂布藻酸双酯钠、透明质酸钠、生理盐水，术后14 d将大鼠处死，肉眼观察肠粘连程度并对粘连组织的基质金属蛋白酶2和金属蛋白酶组织抑制物2水平进行检测。

In this study, astroglia infected with TS-4 strain T. gondii tachyzoite and to investigate the changes of matrix metalloproteinase-12 (MMP-12) and its substrate elastin in the pathogenesis.

本研究我们利用弓虫速殖子（TS-4 strain）感染星状胶细胞的细胞模式进行研究，探讨基质金属蛋白-12（matrix metalloproteinase-12， MMP-12）和其受质弹性蛋白的变化之致病机转。

Objective To construct genetically modified rat bone marrow stem cells expressing exogenetic glial cell-line derived neurotrophic factor which can be used in gene therapy of spinal cord injury .

目的构建表达外源性胶质细胞源性神经营养因子的转基因大鼠骨髓基质干细胞，拟应用于脊髓损伤的基因治疗研究。

The phase constitutions of Magnesia-based dry vibratable materials is designed by the analysis of phase equilibrium digrams, in which the periclase is host crystalline phase, the Spinel, Forsterite and Monticellite et al are the bonding phase in matrix.

本文通过相图分析设计了镁质干式振动料的物相组成，其主晶相为方镁石，基质为镁橄榄石、尖晶石及少量的钙镁橄榄石等。

Neurovascular unit was an integral one that consisted of neuron,vascular endothelial cells,et al.

神经血管单元是指由神经细胞、血管内皮细胞、星形胶质细胞及其周围的细胞外基质组成的一个整体。

The peridotitic komatiite s in Jifen g area of Daxinganling are with fine microspinifex texture.

大兴安岭吉峰地区的橄榄质科马提岩具有良好的显微鬣刺结构，在橄榄石和辉石晶体间隙中充填有基质物质，说明其为火山岩。

All or part of phanerocrysts seems disequilibrium with the glass or ground mass in which they are contained now,however, traditional realization is that the phanerocryst are grow up from the magmas.

传统上认为是从母岩浆中生长出来的斑晶晶体，现在看来全部或者部分并没有和包含它的玻璃质或者基质达到平衡。

The result indicated that PLA is a material able to be used as a carrier of BMP in inducing osteogenesis, it has a better effect of inducing osteogenesis than xenogenous cancellous bone matrix.

结论PLA可以作为BMP的载体修复骨缺损，它比异种松质骨基质载体的成骨效果更理想。

The results demonstrated that laurocapram disrupts the highly ordered lipid structure of stratum comeum and makes the structurs of SC loose,which causes the outermost cell of SC easy to exfoliate and decreases the barrier function of skin for the transdermal absorption of drug;Meawhile, laurocapram penetrating into the intracellular matrix of SC cells fluidizes the filaggrin matrix protein and swells the dermal SC, which could increase the free volume of drug and water content in the SC.

探讨氧酮促进洛美沙星透皮吸收的作用机理。结果表明，氮酮通过以下途径促进药物透皮吸收：（1）作用于表皮角质层细胞间脂质。使角质层变得疏松。细胞间距增大。外角质层细胞易于脱落。降低了皮肤对药物的屏障作用；（2）氮酮进入角质细胞内。与细胞内基质相作用。引起基底角质层肿胀。
