恢复三级侧支循环、促进血管新生是脑梗死防治的重要切入点。在前期理论研究基础上结合血管新生中血管内皮细胞增殖、迁移、分化的微观现象,提出荣气虚滞是脑梗死后血管新生不足的理论基础。荣气气化的"精化气-气生变-变成形"过程能针对性启动或促进脑梗死内源性血管新生,在荣气理论指导下的活血荣络方能促进血管新生,从而具有较好的防治脑梗死作用。

A SOTER management system was developed by analyzing, designing, programming, testing, repeated proceeding and progressing based on the object-oriented method. The function of the attribute database management is inherited and expanded in the new system. The integrity and security of the SOTER database are enhanced. The attribute database management, the spatial database management and the model base are integrated into SOTER based on the component object model (COM), and the graphical user interface (GUI) for Windows is used to interact with clients, thus being easy to create and maintain the SOTER, and convenient to promote the quantification and automation of soil information application.
