Abstract
AIM: To observe the effect of cake-separated moxibustion on the expression of mineralocorticoid receptor (MR), glucocorticoid receptor (GR) and 5-hydroxytryptamine receptor 1A (5-HTR1A) in the hippocampus of rats with functional dyspepsia (FD), and to explore the possible mechanism underlying the therapeutic effect of cake-separated moxibustion on FD.
METHODS: Fifty SD rats were randomly divided into five groups: a blank group (A), a model group (B), a cake-separated moxibustion group (C), a Xiaoyaosan group (D) and a domperidone group (E), with 10 rats in each group. Except group A, the other four groups received chronic restraint stress + excessive fatigue + irregular food for 3 wk. After molding, group C received herbal cake-separated moxibustion for 2 wk, and groups D and E were given Xiaoyaosan and domperidone by gavage for the same duration, respectively. At the end of the experiment, gastric emptying was observed and the expression of MR, GR and 5-HTR1A in the hippocampus was measured by real-time fluorescence quantitative PCR (RT-PCT).
RESULTS: The rate of gastric emptying in model rats was significantly lower than that of group A (P < 0.01), while the rates of gastric emptying in the three treatment groups were significantly higher than that in group B (P < 0.01 for all), although there were no significant differences among the three treatment groups (P > 0.05). The expression of MR in the hippocampus in group B was statistically alike to that in group A (P > 0.05), while the expression of GR and 5-HTR1A was significantly lower than that in group A (P < 0.05 for both). Compared with group B, the expression of MR in the hippocampus in groups C, D and E was statistically similar (P > 0.05), but the expression of GR and 5-HTR1A was significantly higher (P < 0.05 for all). There were no significant differences in the expression of GR or 5-HTR1A among the three treatment groups (P > 0.05).
CONCLUSION: Cake-separated moxibustion can regulate the expression of GR and 5-HTR1A in the hippocampus to accommodate the function of the limbic-hypothalamic-pituitary-adrenal axis to increase the gastric emptying rate of FD rats, and to improve the gastrointestinal motility as Xiaoyaosan and domperidone. This might be one of the mechanisms underlying the therapeutic effect of cake-separated moxibustion on FD.
