At the beginning, an engineering method called semi-empirical reliability estimation method is introduced. Then, a detailed introduction of the bootstrap method, which has been widely applied to small sample reliability assessing since it was proposed in 1979, is made immediately. At last, a promoted virtual sample expanding method, that the reliability test sample size is expanded from 2-3 to 10, is proposed on the basis of predecessors research results. And the new method associated with bootstrap method is used to assess the test life lower limit in the case of logarithmic normal distribution.

The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.

首先利用几何开球原理建立当前样本点的球状邻域，将包含在球状邻域内的所有样本点作为候选近邻点，不但能够保持在数据集稀疏情况下的降维性能的有效性，而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵，用来对球状邻域内的候选近邻点进行更新，优化当前样本点的规则邻域空间，改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。

First, this thesis introduces basic theory of CBR , and studies many aspects of typical part design case , such as case representation, case retrieval, retain etc. Second, regards design code as case code in order to integrate the case with geometrical and non- geometrical information, and realizes the parametric modifying function for 3D solid model in the condition of Pro/E. Third, for the purpose of making true of system's aided design requirement, this thesis brings forward to create part design knowledge base with AI language CLIPS, and integrates the rule based KB into the system; finally, collects and summarizes the knowledge of shaft,gear,sleave, and a sample with ladder—shaft is shown in order to verify the correction of theory research.

PPAR γ agonist displayed obvious renoprotective action,the mechanism was complicated, it could improve the metabolism of glucose ang lipid, depress blood preasure, protect small vessels endothelium,improve the system activity of blood clotting and fibronolysis, antiinflammation, otherwise the action was more obvious with the time passed, at the early stage the effective was better,so encourage the patients to take the medicine earily; when the patients with the mediate reanl function failure, Avandia did not display significantly renoprotective action, side reaction had no difference compared to the control group,was not necessary to regulate the dose of Avandia.But because of the sample size was small, we needed a biger sample to confirm the results. We confirmed that Prol2Ala had no difference in control case,diabetic nephropathy group and diabete group,In diabetic group and diabetic nephropathy group, Ala carriers compared to noncarrier all kinds of biochemical indicators were not different,Prol2Ala did not have association with diabete and diabetic nephropathy. But because of the sample size was small, weneeded a biger sample to confirm the results.

PPARγ激动剂对糖尿病肾病具有明显的保护作用，保护作用的机制是多方面的，除了改善糖脂代谢，降低血压外，还具有保护小血管内皮，改善凝血和纤溶系统活性，抗炎症等多方面的作用，且作用随着用药时间的延长而日趋明显，在疾病的早期应用效果更佳，故提倡早期用药；对伴有慢性肾功不全的患者，罗格列酮对肾脏靶器官的保护作用显现的并不明显，但副作用与对照组无明显差异，不用根据肾功情况调整用药，但由于样本量较小，上述结论尚需大样本进行进一步证实；本实验研究得出Prol2Ala变异在健康对照组、糖尿病组及糖尿病肾病组均无显著差异，糖尿病组及糖尿病肾病组临床各生化指标与Prol2Ala变异亦无相关性，Prol2Ala与糖尿病及糖尿病肾病不相关。
