The histamine in the particles will increase the transmission capacity of capillary and the velocity of the tissue-fluid flow and the superficial shear stress of related mast cell will be increased, which will once again activate mast cells to discharge active substance. Part of the active substance will be absorbed by capillary and the other part will be passed by tissue fluid to a remote place and it will activate the mast cells and the capillaries there. The directional path of the tissue fluid is approximately the same as the meridian, which forms the phenomenon of feeling-along-meridian on macroscale.

脱颗中的组胺等物质会引起毛细血管壁通透性的增加，进而引起组织液流动速度的增加和肥大细胞表面的切应力加大，这样会进一步促进肥大细胞的激活，从而释放更多的活性物质，这些物质一部分被静脉端毛细血管吸收进入血液，另一部分则随着组织液的定向流动向远处，并进一步刺激远处的毛细血管和肥大细胞，而组织液的定向流动途径和传统的经络线走向基本吻合，在宏观上就构成了循经感传现象。

The expression pattern of Triae;CYCD2;1 was analyzed by RNA blot hybridization and in situ hybridization , the results revealed that Triae;CYCD2;1 expression is associated with the proliferation tissues, particularly in meristems and leaf primordia.

组织切片结果显示35S：：Triae；CYCD2；1转基因拟南芥叶片的栅栏组织和海绵组织分化不明显，多数细胞排列已不规则，茎表皮下多层细胞明显变短，苗端分生组织明显增大且具有较多未分化的小细胞。

In order to elucidate the regulation mechanism of RU5 region to BFV gene expression, BFV3026 provirus DNA was used to construct the plasmids containing different deletion of R region, which were cotransfected with luc report gene locatied behind the IP promoter to BL12 cells, and luciferase activities was assayed, confirming that U5 region could repress the initiation function of LTR as well as IP. The BFV structure genes with different deletion of R region were cloned closely behind to heterogenous CMV promoter, then transfected to 293T cells, RT activity was performed, testifying the R region was required for BFV pol gene expression, and also the function domain was identified within the 100n.t. sequence at the 5′end.

以牛泡沫病毒(Bovine foamy virus， BFV)中国株BFV3026原病毒DNA为材料，构建R区系列缺失质粒，通过对其转染细胞中RT水平及对缺失质粒与luc报告质粒共转染细胞中萤火虫荧光素酶活性的测定，确立U5区对于BFV3026两类启动子LTR和IP均具有负调控作用；同时将带有不同R区的BFV3026结构基因片段克隆于异源启动子CMV之下，通过对其转染细胞293T中RT酶活性的测定，确立R区对于病毒结构基因pol的表达具有一定的调节作用，并将其功能区域初步界定在R区5′端100bp内。

Study shows that strengthening body resistance and archaeus herbs have many effects,such as improving and adjusting immunity function,protecting bone marrow,improving haematogenesis function,raising digest and absorb function,improving substance metabolism,preventing gene mutation,inhibiting tumor cell proliferation,inducing tumor cell differentiation or apoptosis,resisting tumor invasion and metastasis,inhibiting formation of tumor vessel and activity of telomerase,etc.It's possibly the result of synergistic effect by multi-pathway and multi-target.
