In four patients with bilateral total corneal stem-cell deficiencies, 3-by-3-mm specimens of oral mucosal tissue were harvested, and the harvested cells were cultured for two weeks with 3T3 feeder cells that had been treated with mitomycin C. Conjunctival fibrovascular tissue was surgically excised from the ocular surface, and sheets of cultured autologous cells were transplanted directly to denuded corneal surface of one eye of each patient, without using sutures.

The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.

皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变，通过岩性地层及年代的推断，兰州地区的风尘序列堆积发育的年代至少为7 Ma，与黄土高原风尘序列堆积底界8～7 Ma基本一致，说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

At the fifth passage, two cell strains were made into cell suspension at l×10^9L^(-1). 0.5 mL was subcutaneously incubated at the inguina of each rat for 8 weeks. Amplified cells were cultured in PGC culture medium and non-adherence culture flask till idiosome formed, adhered and differeotiated.

体内实验取连续传5代的2个细胞株，分别制备浓度为l×10^9L^(-1)的细胞悬液，于每只小鼠两侧腹股沟处皮下各接种0.5 mL，培养8周体外分化采用无私附特性的培养瓶和除去白血病抑制因子的原始生殖细胞培养液，以脱饲养层法悬浮培养扩增的细胞，直到拟胚体形成及贴壁分化。

Methods A wet hip joint's sample from corpse was scaned by CT and all images of every cross-section hip joint's layer was obtained, and an hip joint's model was contructed with Unigraphics NX 2.0 and Solid Works 2006 SP 0.0 software. The models were assembled when simulated total hip arthroplasty after total hip joint prosthetic and ischiofemoral ligament model had been constructured. Analysis was done on von Mises stress distribution and amount of total hip component when simulated seated leg-crossing manuver. The bone and metal components were meshed as rigid bodies, composed of three-dimensional, all-quadrilateral rigid body elements, and hip joint capsule ligament was fully three-dimensional, hexahedral continuum elements representations. Results The current form of this ischiofemoral ligament's reconstruction finite element model provided for multi-body contact, large displacement interfacial sliding, large deformation capsule ligament representation, and clearly reflected the real ischiofemoral ligansent's anatomy and biomechanical behavior. The maximum on Mises stresses at the joint interface was more than that fur an otherwise identical hardware-only construct.

选择成人尸体髋关节行CT成像得到髋关节每层横截面图像，提取边界坐标，利用有限元分析软件Unigraphics NX 2.0和Solid-Works 2006 SP0.0构建出髋关节三维有限元模型及人工髋关节假体，并模拟全髋置换术进行装配，将坐股韧带按其术中重建位置进行构建骨骼与金属模型采用三维十节点四面体实体单元进行网格划分，关节囊六面体连接单元划分，模拟坐位腿交叉动作载荷获取假体撞击过程的角活动度和相应的von Mises应力分布情况结果所构建的多体连接、大界面划移、大变形的坐股韧带重建有限元模型，客观反映坐股韧带真实解剖形态及生物力学行为，增加坐股韧带重建的模型其关节面的最大主应力值大于仅有金属的模型。

Human basic fibroblast growth factor is a single-chain heparin-binding polypeptide. It is a general regulatory mediator for different cells such as endothelial cells and for other cells of mesodermal and neuroectodermal origin, it stimulates cells proliferation, inducing or delaying differentiation.
