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.

Use the Marxist person harmonizes with nature to develop the thought to re- examine just modern mankind's civilization of be placed in the confused stage, the especially natural ecosystem environment was use by us a kind of way that depends on the excessiveness to consume the natural capital to seek the development, can get: Want the real realization Sustainable Development, can't develop the way to look for and can keep on to develop the mode from the economy alone, but must with the Marxism Sustainable Development thought for leading, carry out to develop completely.

用马克思主义人与自然和谐发展思想来重新审视正处于困惑阶段的现代人类文明，特别是自然生态环境被我们用一种依靠过度消耗自然资本来谋求发展的方式，就可以得出：要真正实现可持续发展，就不能单独从经济发展方式去寻求可持续发展模式，而必须以马克思主义可持续发展思想为指导，实现全面发展。
