This paper expounds some new progresses of the research on the life science and related subjects, which including the development of the 3G artificial blood, the study on the new drug based on biological response modifier, the study on slowing down the ageing process of human body, and the study on biological nitrogen fixation, etc.

Structure analysis of different textile-based artificial vascular;

The application and performance requirements of artificial vascular using in the endovascular exclusion (EVE) is described in this paper.

This paper reported the evolution of textile structure and mechanical properties of vascular prosthesis in the level of the whole prosthesis and its monofilaments in terms of the manufacturing process.

The development and status of vascular prosthesis were introduced briefly in the article.

The Course and Direction of Development in the Field of Vascular Prostheses;

The Testing Instruments Design and Experimental Research of Vascular Prostheses Mechanical Properties in Vitro;

The geometric configuration of the vascular prostheses was characterization with the relaxed inner di- ameter and the wall thickness.

It is an important way to change the type of blood and synthesize man-made blood for improving the supply of blood.

This review is a summary of some useful methods and advances about improving clinical applications to small-diameter vascular grafts in recent years,and it points out the developing orientation of small-diameter vascular grafts in the future.
