Here, we report on the first systematic long-term study of fibroblast therapy in a mouse model for recessive dystrophic epidermolysis bullosa, a severe skin-blistering disorder caused by loss-of-function of collagen VII.

我们报道了第一例长期性系统性的关于成纤维细胞治疗隐性营养不良性大疱性表皮松解症小鼠模型的研究。隐性营养不良性大疱性表皮松解症是一种严重的由于VII-胶原蛋白功能丧失引起的出疱性皮肤病。

The results indicate that the larger the concentration of chitosan in the capsules is the slower the release rate of capsule. The biocompatibility tests of the three heparin microcapcules/PLA composite materials show that all materials are negative and have no obvious toxicity. There is no potential hypersusceptibility substance in materials, and the content of pyrogen is conforming to the requirement of organisms.

三种微囊与PLA的复合材料经皮肤刺激试验、皮内刺激试验、热原试验、全身急性毒性试验和细胞培养试验，结果表明，所制备的复合材料在生物学评价试验中均呈阴性反应，材料无明显毒性，材料中不存在潜在致敏性物质，所含热原含量符合生物体的要求。

Results Valvular interstitial fibroblasts were most often spindle-shaped in collagen lattice and there was no difference between normal and rheumatic mitral valve tissues.

结果 正常及病变二尖瓣组织来源的成纤维细胞在胶原凝胶中的形态改变差异无显著性，在胶原凝胶内呈长梭形。

The microscopical observation showed that embryonal suspensor masses developed firstly into early stage proembryos,then into late stage proembryos.

显微观察表明，来自原生质体的胚性胚柄细胞团(ESM：embryogenic suspensor mass)，经早期原胚(ESP：early stage proembryos)阶段形成了后期原胚(LSP：late stage proembryos)。

Can be solid or cystic, have low T2 signal intensity (due to areas composed of interlacing bundles of spindle cells or collagenous septations), which is considered to be a suggestive feature of the diagnosis.

可以是实性或囊性，T2低信号（由于病变由交错的梭形细胞纤维束或胶原分隔组成），这被认为是有助于诊断的特征性改变。

Lavement of pulmonary alveolus of right lung bronchus, undertake left lung of; of cellular classification, computation organizes divide evenly oar to determine group of immunity of collagen content; changes a law to determine sex of STAT1, plaque source grows factor the expression of albumen of 1(PAI-1 of depressor of content of activation of PDGF and fine dissolve zymogen.

右肺支气管肺泡灌洗，进行细胞分类、计数；左肺组织匀浆测定胶原含量；免疫组化法测定STAT1、血小板源性生长因子和纤溶酶原激活物抑制剂1(PAI-1)蛋白的表达。

3 Can partially prevent excess collagen deposition in pulmonary arteries, attenuate hypoxia and MCT-induced pulmonary hypertension and reduce the percentage of nonmuscular intra-acinar arteries.

但对缺氧性肺动脉高压肺动脉壁胶原的抑制以及逆转右室肥厚的作用弱于BAPN.3.764-3很可能通过逆转中膜平滑肌细胞表型的改变而抑制肺动脉壁胶原的过度沉积。4。

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。

A multi-epitope antigen gene pcx was assembled by five highly conserved B-and/or T-cell epitopes, which were selected from C (1-16aa, 132-141aa), E1 (126-135aa), NS3 (139-147aa) and NS5B (768-775aa) protein, as well as a T-cell epitope of tetanus toxin, which was added to enhance T-cell immunity.

针对HCV的高度变异性及免疫特点，在HCV基因产物中优选了5个具有良好免疫原性的高度保守B／T细胞表位，组合成一个多表位抗原基因pcx，这些表位分别来自核心蛋白(1～16aa，132～141aa)，E1(126～135aa)，NS3(139～147aa)及NS5B(768～775aa)，以及破伤风毒素的T细胞表位用以增强T细胞免疫。

Collagen has many useful features such as low antigenicity, controllable biodegradation, biological absorbable properties, haemostatic properties, ability to promote cellular growth and attachment.,which make it an excellent naturally occurring biomaterial, it has a wide application in medicinal industry and clinical medicine.

胶原蛋白是一种天然存在的具有很高利用价值的生物物质，其特有的极低的抗原性、可生物降解性、生物吸收性、止血性能和促进细胞生长的功能，使得近年来在医药工业和医学临床的研究和应用日益广泛。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。

The factory affiliated to the Group primarily manufactures multiple-purpose pincers, baking kits, knives, scissors, kitchenware, gardening tools and beauty care kits as well as other hardware tools, the annual production value of which reaches US$ 30 million dollars.

集团所属工厂主要生产多用钳、烤具、刀具、剪刀、厨具、花园工具、美容套等五金产品，年生产总值3000万美元，产品价廉物美、选料上乘、质量保证，深受国内外客户的青睐
