Abstract:
Objective To explore the effect of Jiawei Wendan decoction on whole regulating function of CaMK/MAPK signal pathway in hippocampus of depression model rats.Methods Isolated depression model rats as research object were living unpredictable chronic stress.Based on the examination of mRNA/protein expression which was the key factor of the signal pathway of CaMK/MAPK and the intersection CREB1 mRNA expression,the relationship between CaMK Ⅱ/RSK protein expression and the CREB1 mRNA expression were analyzed with relation analysis method.Results ① Bidirectional correlation analysis:the respective coefficient (r value) of CaMK Ⅱ protein expression and the CREB1mRNA expression in hippocampus of the model group,Chinese medicine treatment group and western medicine treatnent group were-0.502 (P ＜ 0.01),-0.643 (P ＜ 0.01),-0.408 (P＜ 0.05) ;the respective coefficient(r value) of RSK protein expression and the CREB1 mRNA expression in hippocampus of the model group,Chinese medicine treatment group and western medicine treatment group were 0.550 (P ＜ 0.01),0.687 (P ＜ 0.0 l),0.407 (P ＜ 0.01).②Regression analysis:the respective regression coefficient of CaMK Ⅱ protein (positive direction),RSK protein (negative direction) and CREB1 mRNA expression in the model group,Chinese nedicine treatment group and western medicine treatment group were R 2 =0.472,F =12.983(P＜0.01),R2=0.666,F=28.961(P＜0.01),R2=0.356,F=8.004(P＜0.01).Conclusion The anti-depressant effect mechanism of Jiawei Wendan decoction is to regulate the whole function of the CaMK and MAPK signal pathway and then further up-regulate CREB1 mRNA expression.
