Ea Lieque Hole Experimental Study On The Effect Of Pregnancy Rat Uterus Contraction

Lieque(L 7) is Lou-(Connecting) Point of the Lung Channel,one of the Eight Confluent Points,communicating with the Ren Channel. Ren Channel starts from uterus and has the function of "governing pregnancy".When treating the dysmenorrhea of vacuity cold pattern, Lieque can relax the pain quickly.The patients feel warm and comfortable in the abdomen(uterus).To research what function Lieque has to uterus further,we carried on "The research of the influence and the related factors of Lieque point acts on the movement of uterus by electric acupuncture."by the way of comparing Hegu group,normal group and pregnant group.The result shows that: Lieque point can regulate the amplitude,frequency and intensity of uterine contraction of early pregnant rats by electric acupuncture.The results are as follows:1.It shows that there was no significant difference between all the groups before needling and in the early 5min during needling. The amplitude of uterine contraction of Lieque group had tendency in decreasing continuously and there was significant difference between Lieque group and Hegu group after needling for 5min. Except Lieque group,the other three groups' amplitude of uterine contraction increased.It points out that needling Lieque with electric acupuncture can cause the amplitude,frequency and intensity of rats' uterine contraction significantly decreased continuously.2.After needling,before needling and in 1-5min during needling Lieque,the changes of uterine contraction were not significant.After 5-10min during needling,the amplitude,frequency and intensity of rats' uterine contraction decreased significantly(p<0.01).The decreasing situation still continued after needling 15-20min.3.In 5min before needling and in 1-5min during needling,there was no significant difference between all the groups;In 5-10min and 15-20min during needling,the pregnant group was significantly higher than Hegu group(p<0.05);Hegu group and Lieque group had significant difference(p<0.05);Except lieque group,the other three groups' amplitude of uterine contraction increased gradually and the amplitude of uterine contraction of Lieque group had tendency in decreasing continuously during needling and after removing needles.In 5-10min after removing needles,there was significant difference between pregnant group and Lieque group(p<0.01).The research has the view that Lieque has no direct nerve relation.The way of regulating the changes of uterine contraction is mainly through the regulation of central nervous system and humour factors.Needling Lieque with electric acupuncture can regulate the level ofE2,TXB2,6-K-PGF2α,thus regulate T/P.The result shows:4.After needling,E2 level of Hegu group was significantly higher the other three groups(p<0.05);There was no significant difference between Lique group,normal group and pregnant group.5.After needling,the TXB2 level of Hegu group was significantly higher than the other three groups(p<0.05).Lieque group was significantly higher than pregnant group(p<0.05).6. After needling,the 6-K-PGF2αlevel of Hegu group was significantly higher than the other three groups(p<0.05).Lieque group was significantly lower than pregnant group(p<0.05).From above we can conclude that:Needling Lieque with electric acupuncture has significant function to restrain the uterine contraction of early pregnant rats.
