According to the book of which was written by Sun Simiao in Tang Dynasty, it says :"The unsmoothness of circling of blood and Qi which blocks the pathways of meridians, is the main factor causing disease,", the therapeutic principle is "Clearing the pathways by using acupuncture, warming the meridians by using moxibustion."

文献研究通过对祖国医学有关头痛的研究现状及现代医学对血管性头痛的研究现状综述，认识到本病的中医病机为本虚标实，风、火、痰、虚、瘀为其主要致病因素，脉络闭阻，神机受累，清窍不利为其基本病机。

Results After six passages in BHK-21 cells, cytopathic effect was observed by microscopy. The rescued virus was rejuvenated once in unweaned mice, and then came back to cell passage. We found that the poly tract of rescued virus was shortened when the virus was passaged twice in BHK-21 cells. Although the data of LD50 in mice and TCID50 in BHK-21 cells showed that the virulence and infectivity of genetic engineering viruses were lower than its parental virus, no significant difference was observed between the genetic engineering viruses with the different length poly tract.

我们发现，基因工程毒在BHK-21上连续传代至第6代时，可见明显的致细胞病变效应(cytopathic effect，CPE)；在经过一代乳鼠接种之后再重新适应到BHK-21细胞的过程中，poly区段出现了缩短现象；乳鼠致病性试验和BHK-21细胞TCID50测定结果表明，尽管基因工程毒与母本毒相比毒力偏低，但含有不同长度poly的基因工程毒之间并无显著差异。
