RESULTS: (1) The times of writhing body (9.43 +/- 3.87 and 10.28 +/- 4.23) were significantly lower and the latency period of writhing body (12.43 +/- 3.46, 11.00 +/- 3.65) were longer in the group A and the group A+IC as compared with (15.43 +/- 5.13, 17.00 +/- 3.87) and (7.57 +/- 1.99, 8.43 +/- 2.57) in the group M and group A+I (P < 0.05), respectively. (2) The levels of Cx43 mR NA level and protein expression of acupoint in the group A+I were significantly lower than those of the group N (P < 0.05). (3) OTR and VPR mRNA in the uterus in the group A and the group A+IC were significantly lower than those in the group M and the group A+I (P < 0.05), with no significant difference between the group M and the group A+I (P > 0.05). (4) As compared with the group M, PGE2 level increased and PGF2alpha level decreased in the group A and the group A+IC (P < 0.05).
