The mechanical property testing shows that the seamless PLLA tubes perform excellent radial strength,which indicates that the mechanical properties of biodegradable stents made of these tubes was supposed to be excellent.PLLA and its composites were first used in preparing seamless tubes as antecedency of laser-cut biodegradable coronary stents in china.Finite element analyses of the biodegradable coronary stent model indicate the explorative design basically meets the requirement of reasonable and applicable stents.There is not such kind of research yet in domestic.Optimum laser-cuttting parameters of CO2 laser was cauculated based on experiential formula,within it,biodegradable coronary stents,especially those with complex structure would be manufacutured from seamless tubes quickly by laser microprocessing with high consistency to the design model.The processing efficiency of the CO2 laser demonstrated in experiential formula by us will play an important guiding role in manufacturing biodegradable stents by laser-processing.Our stents that ascribed to laser-cutted,slotted tube stent are proved to be biodegradable, self-expandable and good biocompatible,basically reach the international level on the aspest of manufacturing procedures and design.

Specifically, itcontains 8 chapters.In chapter 1, the formation, structures, properties and the futureprospect of liposome were thoroughly reviewed;In chapter 2, the stibility and permeability of phopholipid -eleostericacid liposome were studied together with the effect of polymerizationof eleostearic acid. This membrane system was very sensitive to 〓,the effect of 〓 was clarified to increase the aggregation/fusion ofliposomes and made the permeability of mixed liposomes much higher;In chapter 3, two polymerizable conjugated diyne bolaamphiphiles were synthesized. They could form very stable mixed liposome, andthe diyne could be polymerized by UV light in bilayer liposomes, as aresult, the stability of mixed liposome against solvent or surfactantafter polymerization were enhanced. In chapter 4, two kinds of amphiphilic amino acids were synthesized andstable liposomes were formed therefrom After the condensationpolymerization of amino acid in bilayer liposomes, stable polypeptide liposomes were obtained, which had lower phase transition temperatureand higher permeability.In chapter 5, four kinds of glycolipids were synthesized and theiraggregation behavior in water was comparied. When incorporated intophospholipid bilayer membranes, they could increase the phase transitiontemperatures and inhibit the aggregation and fusion of mixedliposomesat lower temperature.In chapter 6 and 7, three kinds of steroidal bolaamphiphiles withdifferent chain lengths were synthesized. Incorporation of steroidalmoiety to the center of lipid bilayer membrane obviously increased themobility of lipid membrane and shifted Tc to lower temperature side incomparasion with cholesterol. The bolaamphiphile which was shorter thanthe hosted lipid bilayer membrane thickness influenced the lipid packingmore obviously.

全文共分8章：第一章对脂质体的形成、结构、性质及展望进行了较为详细的文献综述；第二章研究了磷脂-桐酸脂质体的稳定性，通透能力及桐酸的聚合对这些性质的影响；磷脂-桐酸混合脂质体为一类对〓灵敏的脂质体，〓的作用首先是使脂质体集聚然后使脂质体融合，并加速内包荧光物的释放；第三章通过合成两种可聚合共轭双炔双极性双亲分子DDCA，DDOL，研究了共双炔分子在双分子层脂质体膜上的聚合及对脂质体性质的影响，聚合可以提高脂质体相对于溶剂及表面活性剂的稳定性；第四章合成了两类氨基酸为极性基团的双亲分子，它们均可以在超声下形成稳定的脂质体结构；氨基酸基团可以在脂质体上进行缩聚反应，若聚合后脂质体表面仍有足够的亲水能力，则可得到稳定的多肽型脂质体；聚合后脂质体的相变温度降低，通透能力增加；第五章合成了四种亲水基团为单糖基的双亲分子GL-l，GL-2，GL-3， GL-4，研究了它们在水中的分散情况、集合体形态与分子结构的关系；在DMPC双分子层膜中加入糖脂分子可以使脂质体的相变温度提高，阻止脂质体在低温放置时的集聚与融合；第六章-第七章合成了三种不同碳链长度的双极性含胆甾环双亲分子 CL-1，CL-2，CL-3；它们可以象胆固醇一样与磷脂混合形成稳定脂质体，胆甾环基团位于脂质体双分子层膜的中间；与胆固醇的作用相反，它们可以增加磷脂双分子层膜的流动性，降低混合脂质体的相变温度；三种分子的作用与其碳链长度和磷脂双分子层膜的厚度有关，比膜厚度短的分子影响最大。

Gucci (in 1921, Italy) recent years\' Gucci wielded nimbly the brand classics\' element arrives the acme, in piece of logo wind full outstanding, liked expending logo the Taiwan to have 70% sales commodity to have logo to add the body, this sold the travel bag, harness leather product brand most early primarily, in 1947 had the bamboo node handle bamboo node package to be published, the same time had GG logo from the foundation member Guccio Gucci name, in 1952 had the Moccasins shoes which the horse recompensed, in 1966 designed the flowers and plants design silk handkerchief for Moroccan Princess Ge Lisi Kelly, all was classics, until now sees here and there in the Gucci new productIn the detail, in 1990 designer Tom Ford joined, was the Gucci female attire pours into the brand-new spirit.

近年的 Gucci 把品牌经典的元素灵活挥洒到极致，在一片 logo 风中十足抢眼，喜好消费 logo 的台湾更有 7 成销售商品都有 logo 加身，这个最早以贩售旅行袋、马具为主的皮革制品品牌， 1947 年有竹节提把的竹节包问世，同时期从创办人 Guccio Gucci 的名字而有 GG logo ， 1952 年有马衔环的 Moccasins 鞋， 1966 年又为摩洛哥王妃葛丽丝凯莉设计花卉图案丝巾，无一不是经典，至今散见於 Gucci 新品的细节中， 1990 年设计师 Tom Ford 加入则为 Gucci 女装注入全新的精神。

The results showed that the m-PUE had better heat-resistant properties, lower glass transition temperature, higher thermal decomposition temperature and better damping property. The internal friction peak was changed from 10 ℃ to -10 ℃, while the tan δ was changed from 0.28 to 0.46. The hardness, tensile strength and tear strength of m-PUE decreased with the increase of the THEIC content. However, the swelling ratio of PUE was increased meaning a deteriorated solvent resistance property.

结果表明，引入IS环后，PUE的耐热性能有提高；IS改性的PUE的内耗峰比未改性的窄，峰位由10℃移到-10℃，且内耗峰值增大（tanδ由0.28增大到0.46），玻璃化温度降低，而阻尼性能得到提高；引入IS环的PUE的硬度和其它力学性能比未改性的PUE有所降低；随着固化剂中THEIC用量的增加，PUE的溶胀率增大，即IS改性PUE的耐溶剂性变差。
