摘要： 目的探讨电针对先天性脑损伤仔鼠脑组织脑源性神经生长因子（BDNF）表达的影响和机制。
方法给孕17 d的脂多糖组孕鼠腹腔注射脂多糖450 μg/（kg·d），制备脑损伤模型；对照组孕鼠腹腔注射等量生理盐水。脂多糖组仔鼠随机分为非干预组和电针组，电针组于7日龄开始干预，每日1次，干预至28日龄。选取百会、曲池及足三里为干预穴位。对照组、非干预组仔鼠均常规饲养。采用免疫组织化学方法检测1、14、21、28日龄仔鼠脑组织BDNF表达情况。
结果1日龄非干预组脑组织BDNF阳性细胞计数高于对照组，差异有统计学意义（P<0.01），此后两组间比较差异无统计学意义（P>0.05）；电针组各日龄仔鼠脑组织BDNF阳性细胞计数高于非干预组和对照组，差异有统计学意义（P<0.01）。
结论宫内感染可引起脑损伤仔鼠脑组织BDNF阳性表达增强；电针能持续上调脑损伤仔鼠脑组织BDNF阳性表达。

Abstract: ObjectiveTo investigate the effects of electroacupuncture on the expression of brainderived neuotrophic factor(BDNF) in the brain tissues of the young offspring of rats with congenital brain damage.
MethodsPrepare the brain damage models by injecting LPS 450 μg/(kg·d）into abdominal cavity of pregnant rats on d17 and d18;injecting equally sterile NS into abdominal cavity of contrasting pregnant rats.The LPS young offspring of rats were randomly divided into the nonintervention group and the electroacupuncture group.The electroacupuncture group began intervention from d7 until d28,once a day.Select Baihui,Quchi and Zusanli as intervention points.The control group and the nonintervention group were given regular feeding.Immunohistochemistry was used to detect the expression of BDNF in d1,d14,d21 and d28.
ResultsThe expression of BDNF of the nonintervention group was higher than the control group（P<0.01）in d1,and there was significant difference between the two groups.Compared with the nonintervention group and the control group,the expression of BDNF of the electroacupuncture group was higher（P<0.05）in each period and the difference was significant (P<0.01).
ConclusionsIntrauterine infection can cause the increase of the expression of BDNF in neonatal rats with brain damage.Electroacupuncture can persistently increase the expression of BDNF in neonatal rats with brain damage.
