Abstract:
This study was designed to investigate the effect of Sijunzi decoction(SJZD)on the expression of inflammatory factors and autophagic proteins in the hippocampus of senescence-accelerated mouse prone 8(SAMP8)mice and its mechanism.SAMR1 mice were used as control group,and 32 SAMP8 mice were divided into model group,donepezil group,SJZD low and SJZD high dose treatment groups.Y-maze experiment was performed to detect changes in mouse memory function;the expression of NF-κB was detected by immunohistochemistry;the levels of TNF-α,IL-1β,IL-6 were detected by ELISA;the expression of A[3,caspse-1,beclin-1 and LC3-Ⅱproteins in hippocampal tissue were detected by Western blotting.Compared with the control group,the model group mice showed a decrease in total number of entries and alternations,an elevation in the levels of TNF-α,IL-1β,IL-6,Aβ protein and caspse-1 protein,and downregulation in the expression of beclin-1 and LC3-Ⅱ proteins.Both donepezil and SJZD(low-dose group and high-dose group)can reverse these changes in model mice.In conclusion,the mechanism of SJZD in treating Alzheimer's disease may relate to the correction of central hippocampal inflammatory factors and autophagy dysfunction.
