Objective To investigate whether grain-sized moxibustion at Xinshu(BL15)and Shenshu(BL23)can alleviate cognitive decline and other pathologic features in early-stage Alzheimer disease(AD)using transgenic mice with 5 familial AD mutations(5XFAD).Methods The genotype of transgenic mice was detected by polymerase chain reaction.A total of 40 transgenic mice(1.5 months old)were randomly and equally allocated to an AD model group(5XFAD group)or a grain-sized moxibustion group(5XFAD+GM group),with 20 wild-type(WT)mice(C57BL/6J)serving as the normal control group(WT group).Mice in the 5XFAD+GM group were treated by grain-sized moxibustion at bilateral Xinshu(BL15)and Shenshu(BL23).Mice in the WT group and 5XFAD group received no treatment but were restrained to ensure exposure to a similar experimental *** function and memory were assessed with the Morris water maze and Y-maze *** amyloidβ40(Aβ40)and amyloidβ42(Aβ42)levels in the brain were evaluated by enzyme-linked immunosorbent assay;amyloid plaque deposition in brain tissue sections was detected by thioflavin-S staining;the expression of glial fibrillary acidic protein(GFAP),cluster of differentiation 11b(CD11b),brain-derived neurotrophic factor(BDNF),and choline acetyltransferase(ChAT)in the hippocampus and prefrontal cortex was analyzed by *** In the Morris water maze test,compared with the 5XFAD group,mice in the 5XFAD+GM group had a shorter escape latency and more target area crossings and spent more time in the target quadrant(P<0.05).In the Y-maze test,compared with the 5XFAD group,the number of training times of the 5XFAD+GM group was significantly decreased(P<0.05),together with more correct responses(P<0.05).Compared with the 5XFAD group,the levels of Aβ40 and Aβ42 in the brain tissue of the 5XFAD+GM group were significantly lower(P<0.05);in the hippocampus and prefrontal cortex,the total number of amyloidβplaque deposition were significantly lower(P<0.05);the exp
