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。

Three components of peroxide in the activator amongwhich have the different decomposed temperatures made the Vinyl-ester resinsolidified heat discharge increased that gained a bigger solidified degree. Theactivator-adopted quantity can dramatically affect the casting samples performance:eg. When use 1.0-1.4 portions of activator, the casing sample can reach its maximumTensile strength and Bend strength; when use more activator, the polymeric meshworkcontracted which embrittle the casing sample and reduce the dynamic performance; Inthe Pultrusion processing, when CF composed of about 60vo1%, more demould agentcan bring the better processing but degrade the CFRP, normally use around 1.2 portion.

采用具有不同分解温度的三组分有机过氧化物引发剂，乙烯基酯树脂的固化反应放热量增加，固化程度提高；引发剂用量对浇注体的性能影响很大，在用量为 1.0~1.4 份时，浇注体拉伸强度剂弯曲强度达到最高，过多的引发剂使聚合网络减小，浇注体变脆，力学性能降低；在拉挤成型工艺中，碳纤维的体积含量一般为 60%左右，脱模剂增加使加工性能好转但会使复合材料性能下降，一般用量为 1.2 份。

A clear cause-and-effect relationship between excessive myocardial MMP-1 activity, increased mysial collagen degradation, and progression to systolic HF has been shown experimentally through the use of transgenic models and the use of pharmacological MMP activators.53,54 In addition, experimental evidence has been provided showing that following chronic neurohormonal activation, increased synthesis and release of MMPs into the local extracellular matrix of the cardiomyocyte occurs,55 which in turn could contribute to endomysial and perimysial collagen degradation and disruption.

Subsequently,enol methylation of P in basic condition completed the synthesis of malyngamide O.Applied this route to the synthesis of malyngamides Q and R,the chiral unsaturated acid was connected with the vinyl chloride part by amidation,then the resulting product was converted into the corresponding aldehyde,followed by aldol condensation of the aldehyde with the chlorotitanium enolate of pyrrolidone to complete the skeleton of malyngamides Q and R,then the synthesis of them was completed via enol methylation in acid condition.
