    Effect of Electroacupuncture on Hippocampal Functional Activity and Molecular Expression Profile in Rats with Vascular Cognitive Impairment by WANG Zeyu, DING Yanyi, DAI Yaling, YANG Minguang, HUANG Jia, ZHANG Shenghang

    Published 2021-12-01
    “…Barnes maze test was used to evaluate the spatial learning and memory ability of rats; Y maze test was used to evaluate the spatial working memory ability of rats; small animal 7.0 T magnetic resonance resting brain functional imaging was used to analyze the changes of regional homogeneity (ReHo) of hippocampal functional activity; Agilent mRNA expression microarray was used to analyze the differential gene expression of the whole hippocampus genome.Results① Behavioral analysis results: compared with the sham operation group, the Barnes maze escape latency of the model group increased significantly (<italic>P</italic>&lt;0.05), the target quadrant duration percentage decreased significantly (<italic>P</italic>&lt;0.05), and the Y maze alternation rate decreased significantly (<italic>P</italic>&lt;0.05); compared with the model group, the Barnes maze escape latency of the electroacupuncture group decreased significantly (<italic>P</italic>&lt;0.05), the target quadrant duration percentage and the Y maze alternation rate increased significantly (<italic>P</italic>&lt;0.05). ② ReHo changes results: compared with the sham operation group, the ReHo of functional activitives of the bilateral prefrontal lobes, hippocampus and other brain regions in the model group decreased significantly (<italic>P</italic>&lt;0.005); compared with the model group, the ReHo of functional activities of the bilateral hippocampus, prefrontal lobes and piriform cortex in the model group increased significantly (<italic>P</italic>&lt;0.005). ③ Genomics results: a total of 705 genes with 2-fold differential expression of hippocampal mRNA between the model group and the sham operation group (<italic>P</italic>&lt;0.05), of which 195 genes (such as Sytl1, Trpv6, Klhl14, Npsr1, Myh3, Galnt3, Nr4a1, Bmp3, Egr2, etc.) were down-regulated, of which 510 genes (such as Insl6, Efcab1, Akr1b1, Tagln, Glrb, Akr1c13, Kcne1L, Ubap1, etc.) were up-regulated. …”
