    Abstract:
    OBJECTIVE: To observe the mechanism of the optimized traditional acupuncture prescription for accouchement on cervical ripening based on the molecular biology by observing related indices of cervical ripening in late-stage pregnant rats. METHODS: Twenty initial pregnant Wistar rats were randomly divided into an electroacupuncture (EA) group (n = 10) and a model group (n = 10), and other 10 non-pregnancy female rats with same lot were selected as a blank control group. EA group was treated with the optimized traditional acupuncture prescription for accouchement on the 20th day of pregnant, which performed EA at bilateral "Hegu" (LI 4) for 20 min and then at bilateral "Sanyinjiao" (SP 6) for 5 min with 2 Hz/50 Hz sparse-dense wave, while the other groups without acupuncture intervention. The contents of matrix metalloproteinase 9 (MMP-9) and interleukin 8 (IL-8) in cervix tissue were detected by ELISA method. RESULTS: Compared with the blank control group, the contents of MMP-9 and IL-8 in the model group were increased significantly (both P < 0.01). Compared with the model group, the contents of MMP-9 and IL-8 in the EA group were increased significantly (P < or = 0.05). CONCLUSION: Optimized traditional acupuncture prescription for accouchement can increase the contents of MMP-9 and IL-8 in cervix tissue of late-stage pregnant rats so as to promote cervical ripening, and the mechanism of EA in promoting cervical ripening is explained from the perspective of molecular biology.
