ABSTRACT

To explore the pathogenesis of heart and kidney imbalance insomnia and the regulatory effect of Jiaotai Pills, in order to study the changes of central and peripheral neurotransmitters in rat. Insomnia rats with heart and kidney imbalance were induced through intraperitoneal injection with p-chlorophenylalanine(PCPA, 400 mg·kg~(-1)·d~(-1)), and the model rats were intragastrically administrated with Jiaotai Pills(3.3 g·kg~(-1)·d~(-1)) for 7 days. Nine neurotransmitters were determined by UPLC-MS/MS and principal component analysis(PCA) method in serum, urine, brain, heart, liver, kidney and adrenal gland of rats. The results showed that the ratio of 5-HT and 5-HIAA in platelet of insomnia rats was significantly lower than that in the normal group, and Jiaotai Pills had a significant up-regulatory or down-regulatory effect. Compared with the normal group, the changed neurotransmitters in blood of insomnia rats were 5-HIAA, E, NE, DA, Glu and ACH, and except ACH, the changes of 7 kinds of neurotransmitters in urine were more significant, Jiaotai Pills had a significant up-regulatory or down-regulatory effect. Compared with the normal group, all of the 8 neurotransmitters in insomnia rats except HVA were changed. Jiaotai Pills could regulate the neurotransmitters in each tissue of insomnia rats, especially in brain, liver and adrenal gland. In conclusion, insomnia is caused by not only a change of neurotransmitters in brain, but also a series of changes in peripheral tissues. It indicates that insomnia is a systematic imbalance of neurotransmitters. Jiaotai Pills not only regulates the central nervous system, but also has a certain protective effect on other organs, reflecting the multi-target and systematic effect of Jiaotai Pills in the treatment of insomnia.
