[Study on synergic or antagonistic effects of different acupoint groups on vertebro-basilar insufficiency].
OBJECTIVE
To observe the synergic or antagonistic effect of needling acupoints Fengchi (GB 20) and Tianzhu (BL 10), and Jiaji C4-C6 (EX-B2) on vertebro-basilar insufficiency (VBI).


METHODS
Self-control method was used and 20 cases of VBI were respectively treated with acupuncture at Fengchi (GB 20) and Tianzhu (BL 10), Jiaji (EX-B2). Their combination and the changes of vertebro-basilar artery's (VBA) systolic velocity of blood flow was detected.


RESULTS
The VBA's systolic velocity of blood flow after acupuncture were increased in all the 3 groups (P < 0.05 or P < 0.01), with no significant difference among the 3 groups (P > 0.05).


CONCLUSIONS
Acupuncture at Fengchi (GB 20) and Tianzhu (BL 10) or Jiaji (C4-C6 ) or their combination can increase VBA's systolic velocity of blood flow, improving blood supply of vertebro-basilar artery, but they have no synergic or antagonistic effects.
