Abstract:
Objective To observe the effect of electroacupuncture(EA) on the profiles of hippocampal whole-genome expression in depression rats so as to study its underlying mechanism in relieving depression.Methods Thirty male SD rats were randomized into normal,model and EA groups(n=10/group).Depression model was established by chronic unpredictable stress stimulation(forced ice-water swimming,electric shock,tail-clamping,etc.) and lonely raising for 21 days.EA(2 Hz,1 mA) was applied to "Baihui"(GV 20) and "Yintang"(EX-HN 3) for 15 min,once daily for 7 days.The rats' ethological activities(horizontal and vertical movements) were detected with Open-field test in Morris labyrinth,and 1% sucrose solution consumption was detected.After termination of the treatment,the rats were killed and their hippocampal tissues were taken out for analyzing the whole-genome expression with Roche-NimbleGen chips(Rattus norvegicus 12?135 Karray).Results Compared with normal group,the distance of horizontal movement,rearing times,and sucrose consumption at day 21 and day 28 of model group decreased considerably(P
