Objective To investigate the relationship between twirling reinforcement-reduction method and effect of reinforcement-reduction.Method Wistar male rats(n=50) were randomly divided into group A,B,C,D and E(each n=10).Besides group A the model of stress-induced hypertension was established by foot-shock and noise stimulation is other groups.Group A and B were assigned as the control group,group C was treated with acupuncture only,group D with twirling reinforcement method in left Taichong(LR3),and group E with twirling reduction method in left Taichong(LR3).The discharge of cervical sympathetic nerve in different groups was observed at a moment of needling.Result Before acupuncture the discharge frequency histograms and integrals in group B,C,D and E greatly increased compared with those in group A,which indicated that the discharge of cervical sympathetic nerve and blood pressure increased after the model establishment.After acupuncture there was a significant difference between group D and group B or group C(P0.05),which indicated that at the moment of using twirling reinforcement method the discharge frequency of cervical sympathetic nerve and blood pressure increased.There was a great significant difference between group E and group B or group C(P0.01),which indicated that at the moment of using twirling reduction method the discharge frequency of cervical sympathetic nerve and blood pressure decreased.Conclusion The twirling reinforcement-reduction method is effective and correlated to twirling reinforcement-reduction effect.
