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)。

Collagen Ⅱ immunohistochemistry and toluidine blue staining had a weak expression on primary and subcultured cells.

原代和传代后细胞Ⅱ型胶原免疫组织化学和甲苯胺蓝异染反应均较弱。

To examine the expression of MMP-9 and TIMP-1 in villus by using in situ hybridization in patients of asymptomatic infection of CT and Uu.

采用原位杂交法从RNA水平检测无症状沙眼衣原体和解脲支原体感染患者早孕绒毛滋养细胞MMP-9和TIMP-1的表达。

The up-regulation of the expression of MMP-9 perhaps takes part in the accrementition and reconstitution of mesenchymal fibers (Ⅰ-type collagen dominates in mesenchymal, IOD ratio ofⅠ/Ⅲchanged). MMP-9 can facilitate inflammatory cell infiltration, aggravate the development of CAM.

2MMP-9的增高可能参与了骨骼肌间质纤维增生及其构成的改变(Ⅰ和Ⅲ型增多，Ⅰ型胶原与Ⅲ型胶原比值增高)，诱导炎性细胞浸润，加重慢性酒精中毒性肌病的发生发展。

Antibodies against col Ⅲ reacted strongly in the entire pterygial stroma. Conclusions Components of ECM are changed in the pterygium: the sub-epithelial connective tissues and vessels are more prominent in the pterygia than in normal conjunctiva tissues, and abnormal fibers are visible only in the deeper subepithelial connective tissues. This study documents the overexpression of LN and col Ⅲ. They may play roles in cellular adherency, migration and angiogenesis. Also this study documents the overexpression of MMP3 which may degrade ECM in the pathogenesis of the pterygium.

结论翼状胬肉组织中ECM的成分较正常球结膜发生改变，有大量的弹性纤维变性、胶原纤维增生及新生血管形成；col Ⅲ在翼状胬肉组织中表达增加，LN及胶原纤维可能对翼状胬肉中血管形成、细胞粘附和迁移及ECM重建起作用；MMP-3在翼状胬肉组织中表达增加，其对ECM成分的降解作用可能有助于翼状胬肉的形成和向角膜中央侵袭。

The proliferation of medial smooth muscle cells and collagenous fibers of pulmonary arteriole in patients with PH were observed by electron microscopy.

电镜下，中重度PH组肺细小动脉中膜平滑肌增生，外膜胶原纤维密集；轻度PH组肺细小动脉中膜平滑肌细胞和外膜胶原纤维增生轻于中重度PH组；无PH组肺细小动脉结构改变不明显。

DESPRIPTION】 This product adopts natural activated Collagen Peptide as its ingredient, and combines the SAYF(skin activate and youthful factor) and micro spinning technology of elastic fiber to make the eye pact perfectly fit around the eye contour, It can quickly supplement skin moisture and provide quick penetration of nutrient substance to the stratum basale under the guide of the nutrient substance penetrating absorption principle, as well as promote the vitality of skin cells, 95% of which will efficiently absorb and reserve moisture and balance PH value to make the skin elastic and soft, and significantly improve low collagen synthesis which is related to aging. It can also efficiently prevent and reduce eyes' skin wrinkles and cutis laxa to restore the eyes' skin moist and elastic, and implement the nutrition lost because of the fluctuations in temperatures to promote the natural moisture ability of the skin around the eyes to make those skin instantly moisturized, smooth, refresh and outstanding radiant. The wrinkles and fine lines will be reduced at the same time, and the black circles will be no longer apparent.

本品采用天然的活性胶原蛋白多肽为原料，独有的SAYF融合弹性纤维的微纺技术，完美贴合眼部轮廓，可快速补充皮肤在外界所流失的水分，功效营养物质通过透皮吸收原理，快速渗透到皮肤的基底层，并渗提高皮肤细胞活力，其95%有效吸收留住水分，平衡PH值，使皮肤增加弹性和柔软性；明显改善与老化相关的胶原合成低下的现象，有效预防和减少眼部肌肤皱纹及松弛的现象，恢复润泽和弹性，同时补充眼部皮肤在各种温度不定的情况下流失的营养，提升眼周肌肤自然储水力，双眸瞬间滋润、光滑、丰盈，焕然一新，细纹与皱纹减少，黑眼圈变得不再明显。

Transmission electron microscopy examination: epithelium cells degeneration, chromatin margination and collagen arrangement disorder could be observed at early stage after bothsided LASIK.

透射电镜下：BSL术后早期上皮细胞轻微变性，少量纤维细胞核染色质边集，角膜瓣边缘局部胶原排列稍紊乱。1mo时基质胶原纤维排列整齐，直径大小一致。

This investigation include two parts: lThe primary culture, chondroblast induction and evaluation of MSC. 2The chondroblast cultured with compound porous materials PDLLA and PDLLA/chitosan.

第一部分人骨髓基质干细胞的原代分离、体外培养、成软骨诱导及鉴定目的：了解骨髓基质干细胞原代培养的特性及增殖能力，探讨轻度离心和化学限定培养基法诱导骨髓基质干细胞向成软骨方向分化的作用；为软骨组织工程提供足量、合适的种子细胞。
