To investigate the function of Nogo-A in neurons, human embryonic kidney cell line 293FT was used as a model, along with the pathway profiling reporter system to check the involvement of Nogo-A in regulating the intracellular signaling pathway. It was found that over-expression of Nogo-A could activate NF-κB signaling specifically, then followed by using different Nogo-A alternative splicing isoforms and a serial of truncations, it was confirmed that the activation of NF-κB by Nogo-A relied on its N-terminal proline rich domain. Furthermore, by co-expressing the dominant negative mutants of some NF-κB pathway associated proteins, it revealed that the IκBα,TRAF6, Rac/Cdc42 were involved in Nogo-A inducing activation of NF-κB.

为探讨神经元内Nogo-A的功能，以HEK293FT细胞为模型，利用信号途径报告基因系统筛选过表达Nogo-A对多种信号途径的调控作用，发现过表达Nogo-A能特异激活NF-κB信号，利用不同的Nogo-A剪接体和截断体形式研究，证明Nogo-A激活NF-κB信号依赖于其氨基端的proline rich结构域，进一步使用NF-κB信号途径相关分子显性突变体揭示IκBα、TRAF6、 Rac/Cdc42 参与Nogo-A激活NF-κB信号。

It was found that over-expression of Nogo-A could activate NF-KB signaling specifically, then followed by using different Nogo-A alternative splicing isoforms and a serial of truncations, it was confirmed that the activation of NF-kB by Nogo-A relied on its N-terminal proline rich domain. Furthermore, by co-expressing the dominant negative mutants of some NF-kB pathway associated proteins, it revealed that the IkBα,TRAF6, Rac/Cdc42 were involved in Nogo-A inducing activation of NF-kB.

The mechanism of PPS accelerating IEC-6 cells migration was also researched with gene-chip technique. The Altas Clontech Rat cDNA Chip which consisted of 1176 spots representing different functional categories such as heat shock/stress, cell cycle, transcription factors, hormones, metabolism, etc was used. Result showed in cell migration model of IEC-6 cell line, compared with control group, expression of 38 genes in total 1176 genes varied in cells treated by PPS, including 21 genes up-regulated and 17 genes down-regulated. Date analyze showed the mechanism of PPS accelerating IEC-6 cells migration mainly related with promoting the numbers and activity of cellular ion channel, especially 〓 channel.

从以上实验结果中我们可以得出以下结论：四君子汤总多糖具有促进IEC-6细胞增殖、迁移、粘附的作用；四君子汤总多糖无论是对IEC-6细胞增殖、或者迁移的作用均优于各单味药多糖，可能是各种单味药多糖综合作用的结果；多糖可能是四君子汤"益气健脾"药效的主要成分；小肠上皮细胞可能是四君子汤总多糖的作用靶点之一，提示临床采用四君子汤及"益气健脾"法治疗"脾虚证"的疗效机制可能与增强机体的整体免疫和肠道粘膜免疫功能有关。

Traditional theory of self-digestion of amylopsin can not explain the etiology, recently Rindernecht et al brought forward "The theory of excessive activation in white blood cell" to deal with the problem, the theory thinks when the AP occurs, white blood cell releases a lot of cell factors, such as TNF-α、IL-1、PAF、PG、LT et al.
