From the outside to the inside , the body skin is divided into the stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm and stratum basale , after through stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm EGF can reach the stratum basale: accelerate the basal cells prpliferation and differentiation , reverse matured cells' differentiation to make stem cells that will form a " stem cells island " with a certain amount , which accelerate the generation of new cellls , make senescent cells keratinize and shed rapidly , make broken and denatured collagen fibers and elastic fibers repaired , so the skin's elasticity increase , and the wrinkles calm down or disappera gradually .

体表皮由外及里共分为角质层、透明层、颗粒层、棘细胞层、基底层，EGF可以通过透明层、颗粒层、棘细胞层深入肌肤基底层，加速基底层细胞增殖分化，将已经分化成熟的细胞逆分化成干细胞，当达到一定量时，便会形成&干细胞岛&，加速新细胞的生成，让衰老细胞快速角化、脱落，已断裂、变性的胶原纤维和弹性纤维得到修复，皮肤弹性增加，皱纹逐渐平复、消失。

In this work, properties of acrylonitrile-co-ammonium of itaconic acid system was studied in detail in order to accumulate foundation for high performance carbon fibers.

本文将衣康酸铵作为第二单体，系统研究了丙烯腈-衣康酸铵二元体系作为炭纤维前驱体的特点，以期为开发适用于高性能炭纤维的二元PAN原丝奠定必要的基础。

The ligamentous scaffold material were made from the PVA fibers by braiding technique. The mechanical properties of the scaffold materials were measured using the electronic materials testing machine. Human ACL cells were isolated and cultured by tissue explant and collagenase digestion methods, the morphous characteristics of cells and the secretion of collagen protein were measured. In order to observe the biocompatibility between the material and cells, ACL cells were in vitro expanded and seeded on the scaffold materials.

方法］用聚乙烯醇纺丝纤维编织构建韧带支架材料，在电子拉力机上测试该支架材料的力学性质；用组织块和胶原酶消化培养法在体外分离培养人前交叉韧带细胞并对细胞的生长形态和分泌胶原蛋白的特征进行检测，细胞经体外扩增后种植于编织构建的聚乙烯醇韧带支架材料上观察。

Methods The active homograft bioprosthetic pediculated conduit preserved in liquid nitrogen were selected as experimental material and decellularized by sodium dodecyl sulplate containing low osmotic Tris buffer.

方法选取经液氮保存、具有活性的同种生物带瓣管道作为实验材料，用含十二烷基硫酸钠的Tris低渗缓冲液脱去同种带瓣管道存在的细胞；固定剂固定后，分别行HE染色、胶原纤维和弹力纤维染色的光镜和扫描电镜观察、摄片。

Photothermic and photochemical action will be triggered by the radiation of IPL. On one hand, IPL will promote collagen reproducing and recombining which makes the skin more flexible and smooth. On the other hand, the light with long wavelength can easily pass through epidermis layer and will be absorbed selectively in priority by pathological pigments which will be destroyed by high heat, and get the effect of remove pigmentations, vascular lesions and unwanted hair.

当强脉冲光照射皮肤时，会产生生物刺激作用和光热解作用，一方面使皮肤中的胶原纤维和弹力纤维再生并重新排列，恢复皮肤弹性，从而减轻皱纹；另一方面，强脉冲光能穿透皮肤，被组织中的病变色素团优先选择性吸收，热能在不破坏正常皮肤组织的前提下，击碎病变色素团，从而达到治疗毛细血管扩张，祛除色斑，和脱除多余毛发的效果。

P＜0.01. 28d, q=4. 0452, p＜0.05 . Corresponding pathologic result shows that the corneal stromal of height edema increase thickness to have infiltration of inflammation cells with hyperplasia of fibroblast cell and large vessel. The collagen fiber in stromatic layer is dissolved and destroyed seriously, suggesting that in addition to HSV-1's direct destructuring effect, inflammatory cells that might play an important role in the pathology of HSK induce the immune-pathological reaction.

相应的组织病理学研究结果显示（UV-B 14天）：病毒对照组角膜基质层高度水肿、增厚，并有大量中性粒细胞等炎性细胞浸润、成纤维细胞和新生血管增生，胶原纤维肿胀、分解等，说明除HSV-1对角膜组织直接破坏外，炎性细胞介导的免疫病理反应在复发性HSK发病机理是重要的因素。

Results The cells were remeved effectively from cusps and roots of porcine aortic valves by Triton X-100 and sodium dedecyl sulfate in 96 h.

TritonX-100较好的保持了主动脉瓣胶原纤维和弹性纤维的原有排列和分布，并有较好的力学性能。

The result demonstrates that the capillaries and fibrils in dermis of PSS have marked changes, but less marked in that of LS.

结果表明，真皮层毛细血管的内皮细胞、基底膜和胶原原纤维及其周围的基质均发生明显的变化。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
