摘要

目的:通过观察不同电针参数组合针刺对晚孕大鼠体内相关内分泌激素的影响

探讨不同电针参数组合助产处方促分娩效应的内分泌机制。方法:健康成年雌性Wistar大鼠96只

随机分为7个妊娠组与1个正常对照组

妊娠组大鼠采用观察阴栓法制备妊娠模型。受孕后随机分为15Hz组、30Hz组、50Hz组、2Hz/15Hz组、2Hz/30Hz组、2Hz/50Hz组和1个妊娠对照组。电针组均在电针双侧"合谷"穴20min后加针双侧"三阴交"穴5min

强度0.2～0.3mA

根据组别选取不同电针波形及频率。应用酶联免疫吸附测定法检测血清雌二醇(E2)、孕酮(P)和前列腺素E2(PGE2)

并计算雌孕激素比(E2/P)。结果:与正常对照组比较

妊娠对照组血清E2、P和PGE2含量均显著增高(P<0.01)。与妊娠对照组比较

15Hz组、30Hz组、50Hz组及2Hz/15Hz组、2Hz/50Hz组血清E2含量均显著增高(P<0.01

P<0.05);15Hz组、30Hz组、50Hz组以及2Hz/50Hz组血清P含量均显著下降(P<0.01

P<0.05)

且E2/P比值均显著增高(P<0.01);15Hz组、30Hz组及2Hz/50Hz组血清PGE2含量均显著增高(P<0.05)。2Hz/50Hz组血清E2和PGE2含量高于其它电针组。结论:电针助产处方可通过调节孕鼠血清E2、P和PGE2的含量

以及促进E2、P的失衡

促进子宫收缩

从而达到促分娩的目的。但不同电针参数的调节效应有一定差异。2Hz/50Hz疏密波促进宫缩的效应更为明显

为针刺助产处方的推荐电针参数组合。

Abstract

Objective To observe the influence of electroacupuncture(EA) stimulation of "Hegu"(LI 4) and "Sanyinjiao"(SP 6;a classical delivery-facilitating acupoint recipe) at different parameters on endocrine hormone levels of late-stage pregnant rats

so as to find the better stimulation parameters for delivery facilitation.Methods Ninety-six female Wistar rats were randomly divided into eight groups: normal control(normal)

pregnancy(model)

EA-15 Hz

EA-30 Hz

EA-50 Hz

EA-2 Hz/15 Hz

EA-2 Hz/30 Hz and EA-2 Hz/50 Hz

with 12 rats in each group except EA-30 Hz group(n=10).EA stimulation(0.2 to 0.3 mA) was delivered to bilateral LI 4 for 20 min and then bilateral SP 6 for 5 min(25 min).The contents of serum estradiol(E2)

progesterone(P) and prostaglandin E2(PGE2) were detected by ELISA.Results Compared with the normal group

se-rum E2

P and PGE2 contents were significantly increased in the pregnancy model group(P<0.01)

and E2 / P level was down-regulated mildly(P>0.05).Compared with the model group

the contents of serum E2 in the EA-15 Hz

EA-30 Hz

EA-50 Hz

EA-2 Hz/15 Hz and EA-2 Hz/50 Hz groups

serum PGE2 contents in the EA-15 Hz

EA-30 Hz and EA-2 Hz/50 Hz groups

and E2/P levels in the EA-15 Hz

EA-30 Hz

EA-50 Hz and EA-2 Hz/50 Hz groups were significantly increased(P<0.01

P<0.05)

whereas serum P contents in the EA-15 Hz

EA-30 Hz

EA-50 Hz and EA-2 Hz/50 Hz groups were significantly down-regulated(P<0.01

P<0.05).The effects of EA-2 Hz/50 Hz group were significantly superior to those of EA-2 Hz/15 Hz and EA-2 Hz/30 Hz groups in raising serum E2 and E2/P levels(P<0.05

P<0.01).No significant differences were found among the EA-15 Hz

EA-30 Hz

EA-50 Hz and EA-2 Hz/50 Hz groups in raising serum E2

PGE2 and E2/P levels

and among the EA-30 Hz

EA-50 Hz and EA-2 Hz/50 Hz groups in lowering serum P levels(P>0.05).It displayed that the effects of EA at 15 Hz

30 Hz and 2 Hz/50 Hz on the abovementioned 4 indexes were relatively better.Conclusion EA of LI 4 and SP 6 at 15 Hz

30 Hz and 2 Hz/50 Hz can effectively up-regulate serum E2

PGE2 and E2/P levels and down-regulate serum P content in pregnancy rats

which may contribute to its effect in promoting labor.
