DATA SYNTHESIS: Il-17 exerted the biological function after combines with its receptor maybe induced the occurrence and the development of the osteoarthritis by the way of increasing the chondrocyte, expression of inducible nitricoxide synthase and nitrogen monoxide, boosting up the tbe chondrocyte and the expression of MMP-1/3/13, boosting up the activation of the aggrecanase and the collagenase, boosting the decompose of the cartilage proteoglycan and collagen, boosting up the monocyte evocable breakage of the cartilaginous matrix.

资料综合：白细胞介素17通过与其受体结合发挥生物学作用，其可能通过增加关节软骨细胞诱导性一氧化氮合酶表达和一氧化氮产量，增强软骨细胞基质金属蛋白酶（MMP-1／3／13）的表达，增强蛋白聚糖酶和胶原酶活性，促进软骨蛋白多糖及胶原降解，并增强单核细胞对软骨基质的破坏，从而诱导和加速骨关节炎的发生和发展。

He type of ossein in group B was mainly type Ⅰ collagen while that in group A type Ⅱ and it exhibited as a process of fiber formation in group C. The reason for why TGF-β〓 can promote ossification induced by BMP is that can promote the differentiation and proliferation of mesenchymal cells to supply more target cells for BMP, promote the differentiation and proliferation of mature osteocytes and chondrocytes, inhibit metalloproteinase to decrease the destruction of bone tissue and promote calcification of bone matrix.

GF-〓能促进BMP骨诱导作用主要因其能促进间充质细胞的分裂增殖为BMP提供丰富的靶细胞、促进成熟骨及软骨细胞的分裂增殖、促进骨细胞产生Ⅰ型胶原而抑制软骨细胞产生Ⅱ型胶原，抑制金属蛋白酶的活性以减少组织破坏、促进基质钙化等作用而使骨生成能力增加，提示它和BMP具有协同作用。

METHODS: Fresh bovine tendo calcaneus collagen was dispersed in 0.5 mol/L acetic acid, co-precipitated with chitosan and lyophilized. Dry membranes were cross-linked in 0.05% glutaraldehyde for 24 hours. In vitro its degrading rate was measured by use of collagenase degrading test. The chitosan-collagen membrane was implanted to subcutaneous dorsal sites of SD rats. After implantation, histocompatibility, vascularity and degradation were observed in vivo.

Methods Human PDLC cultured in vitro was collected and seeded on Col, HA, HA/Col scaffolds crosslinked by carbodiimide. The influences of scaffolds on cell adhesion and growth were observed by MTT assay. The growth of human PDLC on scaffolds was observed through inverted phase contrast microscope and scanning electron microscope.

Some evidence indicates that the combination of extrinsic, intrinsic and genetic factors all play a role to cause the disc degeneration, with a progressive decrease in proteoglycan content leading to dehydration of the nucleus pulposus, and Type Ⅰ collagen begins to appear in the matrix, the ratio between Type Ⅰ and Type Ⅱ increases. All these cause the swelling pressure, disc height and the disc load bearing ability decrease. The disc progressively herniate and cause radiculopathy and myelopathy.

内因、外因及遗传方面的诸多因素导致椎间盘逐步退变后，其实质就是基质中蛋白多糖的减少，含水量降低，Ⅰ型胶原出现在基质中，Ⅰ、Ⅱ型胶原的比例明显上升，髓核呈纤维样改变，导致椎间盘的膨胀压降低，承重能力下降，椎间高度降低，椎间盘承受的重力不能平均地向各方向传递，致使纤维环疲劳、破裂、髓核突出，造成脊髓或马尾神经受压，引起严重后果。

The results are unsure for experimental use;The rabbit's corneas that were removed with upper-half of corneal limbal epithelium lamella and erased the center corneal epitheliums were transparent with intact corneal epithelium;In the approach,the corneal and limbal epitheliums were burned with a cotton swab socked in 1 mol/L NaOH,there were 4 rabbits' corneal stroma happened perforation or ulcer and symblepharon,and the other one presented corneal epithelium phenotype.This is an applicable method to create the pathological model of corneal limbal stem cell total deficiency.
