Abstract:
This study was aimed to explore the mechanism ofZi-Bu Pi-Yin Recipe (ZBPYR) on autophagy and endoplasmic reticulum stress (ERS) to improve spleen-yin deficiency diabetes-associated cognitive decline (DACD). Rats were randomly divided into the control (cont) group, the diabetes (DM) group, the spleen-yin deficiency (pi) group, the spleen-yin deficiency diabetes (piDM) group, and the spleen-yin deficiency diabetes + ZBPYR treatment (ZBPYR) group. The expression of microtubule-associated protein 1A/1B-light chain 3 (LC3Ⅱ), inositol-requiring enzymeα (IRE1α), c-Jun N-terminal kinase (JNK) were observed by western blot. The results showed that the expression of LC3Ⅱ in the DM group, pi group and piDM group decreased compared with the cont group (P < 0.05); and the expression of LC3Ⅱ of the ZBPYR group increased compared with the DM group and piDM group (P < 0.05). Compared with the cont group, the p-IRE1α of the DM group and piDM group, as well as p-JNK1 in the pi group and piDM group were increased (P < 0.05). The p-IRE1α and p-JNK1 of the ZBPYR group were decreased compared with the DM group and piDM group (P < 0.05). It was concluded that ZBPYR improved spleen-yin deficiency DACD by regulating autophagy and ERS.
