METHODS: Peripheral nerve injury models of New Zealand rabbits were established. The immediate repairing group received suture immediately after injury; For the other three groups, the two broken ends of their nerves were fixed on sarcolemmas temporarily and their wounds were sutured layer by layer. Then they were opened respectively at week 2, week 4 and month 3 after injury, to receive epineural suture with non traumatic 10-0 nylon suture under operating microscope, after which wounds were sutured again.

Analysis of nuclear extracts of human cells has indicated a similar excision repair mechanism for nick-directed mismatch correction in higher cells, and several reconstituted systems that rely on purified human proteins have been described, such as hMutSα、hMutSβ、hMutLα. Recently, scientists discovered that nickel could be inhibitors of DNA repair. Nickel can greatly enhance the mutagenicity and genotoxicity of compounds in cigarette by inhibiting the nucleotide excision repair pathway in human cells. We have confirmed that nickel could inhibit MMR of E. coli and human and presumed that nickel inhibited repair before MutH incision of the MMR in E. coli. However, there is no evidence of mechanism of nickel inhibiting MMR in human cells.

镍是存在於香菸中的微量金属，近年来有学者发现镍是DNA修复反应的抑制剂，长期抽烟的人会容易因为香菸中化合物攻击DNA而引起突变，进而引起肺癌，而镍会抑制核苷酸移除修复系统（nucleotide excision repair；NER），所以使得体内的DNA损伤无法修复；过去实验室已经证实大肠杆菌的核酸配对错误修复系统会受到镍等重金属的抑制，并且推测出镍的抑制反应是抑制在修复反应的上游nicking的步骤；另外，也证实了人类的核酸配对错误修复系统也会受到镍的抑制，然而还没研究证实会抑制在核酸配对错误修复反应的哪个步骤。

Cavitations in foreign hydraulic turbines appear in clear water condition, so its destructive extent is not far more serious than in Yellow River hi our country. Stronger stiffness and more agility are required for Special-purpose robot for hydraulic turbine repair used in our country. Foreign robot for hydraulic turbine repair could not satisfy our working require, so we develop special-purpose robot system that is used to polish and weld repair cavitate flow path surfaces of hydraulic turbines on all location.

The fifth chapter has studied the ways to deal with the different kind historic furniture in its conservation and restoration, mainly discussed its deteriorated factors, common flaws, corresponding restorable methods, the technological procedures of its restoration, the key technology for the excavated furniture, the traditional technology used in restoration, the reproduction of antique furniture and its maintenance and protection.

第五章探讨了明清古旧家具修复和保养方式及常见的工艺流程，主要从损坏的因素、常见的缺陷及相应的修复方式、修复的工艺流程、出土文物家具的修复和保护的关键处理技术、修复中的传统工艺、文物家具复制及古旧家具维护和保养等多层面展开讨论。

RESULTS: During 10 - 12 weeks, in cuntrol group: The defect area was repaired by white and soft tissue that had no resistance to press. The repaired tissue was still lower than the surrounding articular surface with clear boundary. By histological observation, it was found that the defect was repaired by the mechanism similar to inflammatory reaction and the defect is ultimately filled by the hyperplasia of hyaline degenerative fibrous tissues. In filling group: the defect was repaired by semi-transparent, smooth, textured tissues with polish that had resistance to press as well as elasticity. The repaired tissue was almost similar to the shape of the surrounding cartilage,difficult to be distinguished. After histological observation, it was found that there was no inflammatory reaction, but active hyperplasia of inner bonetissue and cartilage tissues; a lot of osteoid tissues and trabeculation were found. Newlborn cartilage was fused with surrounding cartilage tissue and connected with surrounding tissues.

结果：10～12周，对照组：缺损区由白色、质软、按压无阻抗的组织修复，修复组织仍低于周围关节面，边界仍清晰可辨，组织学以类似炎症反应的机制修复缺损，最终以透明变性的纤维组织的增生来填补缺损部位；填充组：缺损区由半透明状、质韧光滑有光泽，按压有阻抗并有弹性的组织修复，修复组织与周围软骨外形上已基本相似，不易区分，组织学未见有炎症反应的过程，内骨组织和软骨组织增生活跃，并可见大量类骨组织和骨小梁形成，新生软骨和周围软骨组织融合，并与周围组织连接。

The artifical fillers are hung under the plant floating bed then the remedial system combined by plant and microorganism came into being. The remedial effectiveness of the system was visibly better than that of the phytoremediation alone. So when the temperature is higher the remedial system combined by plant and microorganism is the preferable remedial technique to remedy contaminated water. In autumnal end and winterly outset, the temperature is lower, the plants begin to fade and die, and the plant must be harvested lest the relict of plant should contaminate water again. At the same time the technique combined by immobilized nitrogen cycling bacteria and microorganism which already existed in the water was used to remedy contaminated water.

将人工填料悬挂于植物浮床下，形成植物和微生物相结合的修复系统，其修复效果明显好于单独植物修复技术，因此温度较高时用植物和微生物共同结合的生物修复技术修复水体污染；秋末冬初温度较低时，植物开始死亡，必须将植物收割，以免植物残体造成二次污染，此时用固定化氮循环细菌和水体中原有微生物相结合的技术来修复水体的污染。

Foreign robot for hydraulic turbine repair could not satisfy our working require, so we develop special-purpose robot system that is used to polish and weld repair cavitated flow path surfaces of hydraulic turbines on all locations.

For maintain the genome integrity and fidelity. DNA repair processes are classified into pathways responsible for repairing specific classes of DNA damage, although recent data indicated that some proteins function in multiple pathways. Base excision repair occurs through excision of a damaged region, followed by fill-in repair synthesis using the opposite strand as a template. Mismatch repair operates on base mismatched and small loop-outs that arising during replication by misincorporation or slippage on the template strand. Nucleotide excision repair removes photoproducts from u.v. radiaton and bulky adducts from a multiple of chemicals. DNA double-strand breaks may be rectified by either homologous recombination repair and nonhomologous end joining pathways where both strands of the DNA duplex are damaged.

DNA修补基因可藉由不同的机制对不同程度的DNA损害进行修复，虽然近来已有文献指出，一些DNA修复蛋白可能参与多种DNA修复机制，不过一般可分为下列四种DNA修复机制：碱基删除修复(Base Excision Repair； BER)，即对较小的DNA损伤，进行修复；核苷酸错误配对删除修复，即对复制时所产生的核苷酸配对错误或模板滑动造成的DNA损害进行修复；核苷酸删除修复(Nucleotide Excision Repair； NER)，即对因紫外线或有机化合物所造成的较大损伤进行修复；以及双股DNA断裂修复(Double-Strand Breaks； DSBs)，即对双股DNA断裂进行修复，此机制又可分为同源染色体的重组与末端接合两种主要路径，对受损的DNA进行修复。
