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。

The results revealed that a nano-fibrous matrix made of PHA materials had been formed through unique solution process, the nano-fibrous matrix is similar to the structure of collagen, which is the main component of extracellular matrix, and its average diameter of the fiber is ranged 80～350 nm.

同时，通过扫描电镜的检测发现了具有纳米纤维网状结构的PHA新型支架材料，这种通过溶剂处理法获得的PHA纳米纤维支架与细胞外基质的主要成份胶原蛋白的结构非常类似，它的纤维直径平均大小在80-350 nm 之间。

There were more fibroblasts, the collagen increased in model control group. After 30 days, the fibroblasts of model control group were hyperemic, scattered red blood cells could be found, and capillaries were proliferated. Fibrous tissue arranged in rows in the acupotomology intervention group and the blockade control group.

造模后30 d模型对照组成纤维细胞增生，可见红细胞散在分布，有增生的毛细血管；针刀干预组与封闭对照组可见纤维组织排列成行；针刀干预组较其他各组胶原纤维形成减少，瘢痕面积小。

Result The flexibility of the scaffold material was powerful. The load-elongation curve of the mechanical testing was similar to that of ACL, the maximum load, the ultimate stress and the Young's modulus of the scaffold materials were 52.61 N, 14.96 MPa and 202.08 MPa respectively. Human ACL cells displayed the representative characteristercs of the ligamentous fibroblasts, and synthesized extracellular matrix, such as type Ⅰand Ⅲ collagen protein. The scaffold materials had no cytotoxicity. Human ACL cells adhered, grew and proliferated well both on the surface and in the holes of the scaffold materials.

结果］韧带支架材料的柔韧性强，拉力测试的负荷－拉伸曲线与韧带的拉伸曲线相似，其最大负荷、极限应力和弹性模量分别为52.61N、14.96MPa和202.08MPa；体外分离培养的人前交叉韧带细胞呈典型的成纤维细胞特征，能在体外分泌Ⅰ、Ⅲ型胶原等细胞外基质；支架材料无细胞毒性，人前交叉韧带细胞可在支架材料上黏附、生长并分泌细胞外基质。

Finally, we established rat model of PF induced by bleomycetin, and observed the interventional action of phenol total base to model. The analysis of experimental result including pathematologic and tissue biochemical indicator showed phenol total base of plumula nelumbinis have some therapeutic action to rat model of PF induced by BLM.

通过病理学观测及组织生化指标的检测(SOD、MAD、GSH一PX、Hyp)，说明莲子心酚性总碱对博莱霉素致大鼠肺纤维化有一定治疗作用，可能的作用机制：降低肺纤维时胶原含量；抑制肺成纤维细胞的增殖；抗自由基和抗脂质过氧化作用及提高了机体内GSH一Px含量。

In electricity plus thermal group, the pathologic alterations were slighter than model group; there was little crack on the surface of cartilage, with intact collagen fiber structure and less pyknotic chondrocytes. Although some chondrocytes shrank, there were intact cell organs in many chondrocytes even chondrocyte cluster in some regions.

疏密波+热软膜组在病理程度上的改变明显轻于模型对照组，软骨表面裂纹少，胶原纤维结构基本完整，固缩的软骨细胞少，虽可见部分退变的软骨细胞，但部分软骨细胞具有较多的细胞器，某些区域形成软骨细胞簇。

Results:(1) In clinical pathology, swelling, denatured, even necrosis and putrescence could be picked out; Collagen fibers in tendon remarkedly swelled, and tissue structure disarranged, and collagen even ruptured, broken and dissolved; Obvious denature, apoptosis and necrosis could be found in tendon cells. There appeared to be a big accumulation of inflammatory cells.

结果 （1）临床病理组织学观察发现：肌腱组织肿胀、变性、甚者坏死、腐败；肌腱内胶原纤维肿胀明显、组织结构紊乱，失去正常排列，甚者出现胶原断裂、破碎、溶解等现象；腱细胞可见明显的变性、凋亡和坏死；病变部位可见大量炎性细胞聚集。

With the increase of cell density, soma was slenderer and slenderer and like fibroblast.② Growth curves of PDMCs: Growth latency ranged from 2 to 8 days after cell inoculation. During this period, adherence was observed gradually but not obviously amplified. Eight days later, cells entered log growth phase.

结果：①多分化潜能细胞的原代培养情况：胎盘组织消化后获得细胞中仅有少量的贴壁细胞，经两周后逐渐形成扁平单层细胞，呈漩涡状生长或成簇生长，随着细胞密度的增加，胞体变得细长，形态类似成纤维细胞。

The methods of sticking tissues piece to culture primary hFCECs and mouse 3T3 fibroblast conditioned medium to culture passage hFCECs were established;2.The Proliferative capacity of corneal limbus hFCECs is better than central hFCECs.3.3T3 conditioned medium could markedly promote the proliferation of epithelial cells

结论一、组织块贴壁法原代培养人胎儿角膜上皮细胞以及小鼠3T3成纤维细胞条件培养液传代培养方法基本建立；二、人胎儿角膜缘部上皮细胞增殖能力优于中央部；三、3T3细胞条件培养液能促进角膜上皮细胞的增殖。

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。
