The styrene-acrylate spheres were coated with the TiO2 colloidal particles via electrostatic effect and hydrogen bond interactions with the increase of aging time, thus the film-forming capability of the solution was changed. The poor film-forming capability results in the formation of the porous structure with dense, homogeneous island morphology. Then the TiO2 porous films with dense pores can be obtained after two coating-dissolving cycles.

结果表明，TiO2溶胶与苯丙乳液混合后，陈化时间的延长有利于TiO2胶粒通过静电、氢键作用在苯丙乳液粒子表面形成吸附层，从而改变涂膜液的成膜性，形成较为密集、且均匀分布的岛状多孔结构，在此基础上经两次涂膜，即可获得具有致密孔洞的TiO2多孔薄膜。

Thermal discomposing temperature was determined by DTA, and the change of structure and element composition of surface film with inhibitor after high temperature tests were studied by means of IR and XPS etc.

用DTA研究了OM-2的热分解温度。用IR和XPS等方法研究了高温试验后产物的结构变化以及成膜试片表面的元素组成。

Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.

资料与方法RA模型组：早期RA家兔模型15只，品种及体重接近。对照组：正常家兔10只，品种及体重接近。RA家兔模型制作方法：选取15只成年家兔，体重、品种接近，将卵蛋白溶解于生理盐水，配成浓度为20mg/ml的溶液，与等量完全弗氏佐剂混匀，注入家兔肩胛区皮下致敏，每只家兔每次注射1ml，于肩胛区5个不同区域注射，每周一次，连续注射3周而致敏，第4周向膝关节腔注射卵蛋白生理盐水溶液，每只关节腔注射5mg卵蛋白，15只家兔膝关节全部注射，24h内此关节直径和表面温度大幅度上升，以后缓慢下降，至14～21d达到平台期，发病率达100%。造模成功后第1～4周为早期改变，第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组，其股骨髁软骨的厚度与对照组相比无明显差异，其软骨下骨皮质与对照组相比无明显改变。

Serofluid production is simple, general selection of fresh endive, alfalfa, water chestnut, such as shepherd's purse wild fermentation introduction, in the Ci Guan Sheng cover within three days later serofluid mold.

浆水制作很简单，一般选用鲜嫩的苦苣、苜蓿、荠荠菜等野酵引子，盛在瓷罐内盖好，三天后即成浆水。

The method of embryonic body formation was used for endoderm/mesoderm commitment before the following pax4 gene transfection.

首先使胚胎干细胞形成embryonic body，四天后将EB打成单颗细胞。

The size of the epicondyles in Chinese is significantly smaller than that of the Westerns. The ratio between anterior posterior width of the medial epicondyle and the width of the STEA is 0.84, and is 0.87 between anterior posterior width of the lateral epicondyle and the width of the STEA. The distance from the epicondyles to the joint line is helpful to locate the STEA. The reliability is poor to locate the STEA by touch or PCL.

国人股骨远端上髁解剖大小明显小于欧美国家人群，股骨远端内外上髁的前后径与STEA宽度成一定比例，STEA的骨性标志与膝关节后侧及远端关节线的距离可为定位STEA提供一定帮助，通过术中触摸或PCL定位STEA的可靠性差。

Report from our correspondent (photography reports reporter Deng Yu) by April, a few 80 epigenesis lad founds commonweal website " achieve enjoy "(Www.chxcity.com), the commonweal on intercurrent hauling acts -- for size alley child, the 9 big Chengdu such as the railroad that become fill " ground mark " the building adds a brick, for blessing of disaster area pray, cheer for Chengdu.

本报讯四月底，几名80后成都小伙儿创建公益网站"创享之都"(www.chxcity.com)，并发起网上公益行动——为宽窄巷子、成灌铁路等9大成都"地标"建筑添砖，为灾区祈福，为成都加油。

Results In control group,three weeks after the epithelization of the wound,the thickness of the hypertrophic tissue was 3-4 times of ventro ear skin. Under microscope,the dermis was hyperplasia and got thicker,consisted with amount of fibroblast cells,collagen and vessels,the collagen was untidy,nodule or vortex,and the cartilage could be observed in some region.

结果：对照组兔耳创面上皮化后3周时，增生厚度为兔耳腹侧皮肤全层厚度的3～4倍，镜下可见真皮组织明显增生、变厚，由大量成纤维细胞、胶原组织及血管组成，胶原排列不整齐，呈结节或旋涡状分布，部分可见对应处软骨细胞增生。

If non-absorbent cotton wrapped with gauze sewn into the intestine-shaped instead of gauze, better. 24 hours after the gauze out slowly, out should be preceded by intramuscular injection of oxytocin, ergometrine agents such as uterine contractions.

若能用纱布包裹不脱脂棉缝制成肠形代替纱布条，效果更好。24小时后缓慢抽出纱布条，抽出前应先肌肉注射催产素、麦角新碱等宫缩剂。
