Abstract:
Objective To explore the mechanism of Zibu Piyin Recipe (ZBPYR) on spleen yin deficiency diabetes-associated cognitive disorder (DACD). Methods The rats were randomly divided into control group, diabetes mellitus (DM) group, spleen yin deficiency group, spleen yin deficiency DM group and spleen yin deficiency DM+ZBPYR group (treatment group). Type 2 DM models were established by high-fat food feeding and low dose STZ intraperitoneal injection for 4 weeks. Then the classical compound method was used to construct spleen yin deficiency rat models by improper diet, over exertion and yin fluids exhaustion. The treatment group was given ZBPYR by gavage for 15 days, and the other groups were given the same amount of normal saline. Then cerebral cortex, hippocampus, stomach and liver were obtained and the changes of protein expression of PDHE1α in them were observed by Western Blot. Results The protein expression of PDHE1αin cortex of DM group and spleen yin deficiency DM group were lower than control group (P<0.05). PDHE1α expression of treatment group in cortex and stomach increased more significantly than spleen yin deficiency DM group (P<0.05). The expression of PDHE1α protein showed no significant difference among all groups in hippocampus and liver. Conclusion ZBPYR improved spleen yin deficiency DACD by regulating PDHE1αin cortex and stomach.
