[Effect of Wangbuliuxing combined with massage on breastfeeding and lactation function in cesarean section women].

OBJECTIVE: To explore the effect of Wangbuliuxing (semen vaccariae) combined with massage at breast and acupoint on breastfeeding and lactation function in cesarean section women. METHODS: A total of 120 cases of cesarean section women were randomly divided into an observation group and a control group, 60 cases in each group. The control group was treated with routine nursing. On the basis of the control group, the observation group was treated with oral administration of Wangbuliuxing decoction, twice a day for 7 days; in addition, massage at breast and acupoint (Zhongfu [LU 1], Yunmen [LU 2], Danzhong [CV 17], 2 min per acupoint per time) was given, twice a day for 7 days. The onset time of lactation, 48-hour postpartum lactation volume, breast swelling and pain, 42-day postpartum breastfeeding were compared between the two groups; the serum levels of prolactin at 48 and 72 h after delivery were measured, and the body mass of newborns at birth and 42 d after delivery were recorded. RESULTS: The onset time of lactation in the observation group was earlier than that in the control group (P<0.05), the 48-hour postpartum lactation volume was higher than the control group (P<0.05), and the breast swelling pain 48 h after delivery was lighter than the control group (P<0.05). Forty-two days after delivery, the success rate of breastfeeding in the observation group was 91.7% (55/60), which was higher than 76.7% (46/60) in the control group (P<0.05). At 48 and 72 h after delivery, the level of serum prolactin in the observation group was higher than that in the control group (P<0.05). On 42 d after delivery, the body mass of newborns in the two groups was higher than that at birth (P<0.05), and that in the observation group was higher than the control group (P<0.05). CONCLUSION: Wangbuliuxing combined with massage at acupoint and breast could significantly shorten the onset time of lactation, improve the lactation volume, effectively improve breast swelling and pain, increase breastfeeding rate and promote the growth and development of newborns.

Involvement of galanin and galanin receptor 1 in nociceptive modulation in the central nucleus of amygdala in normal and neuropathic rats.

The present study was performed to explore the role of galanin and galanin receptor 1 (GalR 1) in nociceptive modulation in the central nucleus of amygdala (CeA) in normal rats and rats with neuropathy, and the involvement of GalR 1 and PKC was also investigated. The hindpaw withdrawal latencies (HWLs) to thermal and mechanical stimulations were increased in a dose-dependent manner after intra-CeA injection of galanin in both normal rats and rats with neuropathy. The increased HWLs were significantly attenuated by intra-CeA injection of galanin receptor antagonist M40, indicating an involvement of galanin receptor in nociceptive modulation in CeA. Furthermore, intra-CeA administration of the GalR 1 agonist M 617 induced increases in HWLs in normal rats, suggesting that GalR 1 may be involved in galanin-induce antinociception in CeA. Additionally, intra-CeA injection of the PKC inhibitor inhibited galanin-induced antinociception, showing an involvement of PKC in galanin-induced antinociception in CeA of normal rats. Moreover, there was a significant increase in GalR1 content in CeA in rats with neuropathy than that in normal rats. These results illustrated that galanin induced antinociception in CeA in normal rats and rats with neuropathy, and there is an up-regulation of GalR1 expression in rats with neuropathy.
