Methods investigate the possible relationship between the analgesic effect of acupuncture Connexin 43 gene knock-out mice were randomly divided into 4 groups： a wide type （WT） control group, a WT acupuncture group, a heterozygous （HT） control group and HT acupuncture group. Hot-plate test and writhing response induced by acetic acid were used for investigating the different analgesic effect of acupuncture on HT and WT mice. Results There was no significant difference in the basic pain threshold value between HT and WT mice （P 〉0.05）. Acupuncture could significantly increase the pain threshold value, prolong the latency period of writhing body and decrease the number of writhing body as compared with pre-acupuncture in WT and HT mice （P 〈 0.01 or P 〈 0.05）. The pain threshold, latency period of writhing and number of writhing body in HT mice were less than WT mice post-acupuncture （P〈0.05）. Conclusion Connexin 43 gene knock-out might partially inhibit the analgesic effect of acupuncture, suggesting that connexin 43 is possibly related with meridians and the effect of acupuncture.展开更多
