Generally, the figure of the one in the cave is smaller, the growing speed is very slow and the season growing is not obvious, mainly because of lack of food and the low temperature (around 15℃) in the karst cave water. In the numerable characters, the anal fin, scale of encircle tail and gill raker of the one in the cave are in the tendency of increasing so as to adapt to the narrow water passage in the karst cave, while the length of the cave Cyprinus carpio is lengthening comparing with the one on the surface.

结果表明：从总体看洞穴鲤鱼的体形比地表鲤鱼小，生长速度缓慢，季节生长不明显，主要影响因子是洞穴内食物贫乏和水温较低（15℃左右）；在可数性状中，洞穴鲤鱼的臀鳍条、围尾柄鳞和鳃耙有增多趋势，即增加了感觉细胞的附着基底；为适应洞穴水流域的狭窄通道，洞穴鲤鱼的体长相对地表鲤鱼而言有延长现象。

石02具有介于钦和HAp之间的热膨胀系数，起到过渡层的作用，从而可降低烧结后涂层和基底之间的残余应力，减少 HAp涂层裂纹的发生，进一步改善了涂层的结合性能。

Acellular Extracellular Matrixis three dimensional mesh stent which mainly composed by vessel of basilar membrane and coated by epineurium. As a bioactive nerve graft,it own natural construction,lower immunogenicity.

脱细胞神经细胞外基质材料是以SC基底膜管为主、以神经外膜为外套的完整的三维网状支架；它作为有生物活性的神经替代物，具有良好的仿生性，较低的免疫原性。

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

Objective:to primarily find out the effect about luteolin rivalizing ototoxicity of gentamicin.methods: in this experimental study,gentamicin group was compared to the group of gentamicin with different dose of luteolin (10 mg,20 mg).the changes in hearing and vestibule function were discovered by measuring the threshold of abr and the frequency of eng.the method of cochlear preparation stained with sdh was used to observe morphological changes in cochleas.results: the auditory examination results showed that the thresholds of the group of gentamicin with different dose of luteolin were higher than the one of the gentamicin group,and the difference was significant in statistics.the morphology analysis result was consistent with auditory examination.

目的：初步了解木樨草素对庆大霉素耳毒性的影响。方法：设庆大霉素组与庆大霉素加不同剂量木樨草素（10 mg、20 mg）两组，并进行组间比较，观察听性脑干反应阈值、眼震电图的频率，了解其听功能及前庭功能的变化。结合耳蜗基底膜铺片琥珀酸脱氢酶染色方法观察耳蜗形态学变化。结果：听功能检查结果显示，庆大霉素加不同剂量木樨草素组的abr阈值明显低于庆大霉素组，经统计学处理，差异有显著性。形态学检查结果与听功能检查结果一致。

And in combination with the project practice the paper approaches to the arrangement of the prospecting option and compares the common option of the foundation pit enclosure of tunnel and the anti-floating design of foundation bottom.

本文对上海地区城市下立交工程的勘察设计进行了分析总结，并结合工程实践对勘察方案的布置进行了探讨，对地道基坑围护、基底抗浮设计的常用方案进行归纳比较，为今后下立交工程的勘察设计工作提出建议和参考。

The odontoid vertebra space in the model was divided into lattices and the stress area of the odontoid vertebra was identified by force loading and analyses. It was found that the structure of the stress concentration area was closely related to the development of split sections. Therefore,when the odontoid process is attacked by the external force along its vertical plane,its waist is likely to break and type II fracture occurs. And the break also possibly appears in its base,in this way,type HI fracture occurs.

确定其材料性质、单元类型并控制好网格划分精度后，通过力的加载与分析，找出枢椎的结构应力区，根据结构的应力集中区与其断裂时断裂面走向的密切关系，从而判断出当外部载荷沿齿突中性矢状面不同角度作用，即齿突受到来自其矢状面的外部冲击时，容易在齿突腰部发生断裂，形成枢椎齿突Ⅱ型骨折，也可能在基底部发生断裂，形成枢椎齿突Ⅲ型骨折。
