    摘要:

    目的 观察电针百会、印堂对抑郁样小鼠社交与空间记忆能力的影响。方法 将48只SPF级雄性C57/BL6小鼠随机分为对照组、模型组、电针组、氟西汀组各12只,采用慢性不可预见性温和性应激制备抑郁样小鼠模型,电针组给予电针百会穴、印堂穴(连续波,2 Hz,1 mA,30 min/d),氟西汀组给予10 mg/kg氟西汀,每日干预1次,连续干预10 d。使用糖水偏好实验、强迫游泳实验、悬尾实验、三箱社交实验、Y迷宫实验评估各组小鼠抑郁行为、社交能力及空间记忆,使用离体电生理技术记录小鼠海马场电位,评估各组小鼠突触可塑性。结果 与对照组比较,模型组小鼠糖水消耗、社交时间、Y迷宫新奇臂进入次数与探索时间、fEPSP斜率均明显降低(P<0.01),强迫游泳与悬尾实验不动时间均显著增加(P<0.01)。与模型组比较,电针组、氟西汀组小鼠糖水消耗、社交时间和Y迷宫新奇臂进入次数及探索时间、fEPSP斜率均明显增加(P<0.05或P<0.01),强迫游泳与悬尾实验不动时间均显著减少(P<0.05或P<0.01)。与氟西汀组比较,电针组小鼠糖水消耗、悬尾实验不动时间、fEPSP斜率均明显降低(P<0.05),强迫游泳不动时间、社交时间和Y迷宫新奇臂进入次数及探索时间均无明显改变(P>0.05)。结论 电针能够改善小鼠抑郁样行为,并且可以改善海马突触可塑性,改善小鼠社交能力与空间学习记忆。
