摘　　要：OBJECTIVE:To investigated the effects of suspended moxibustion stimulating Shenshu(BL23)and Guanyuan(CV4)acupoints on the amygdala and HPA axis in our rat model and elucidated the possible molecular mechanisms of moxibustion on kidney-Yang deficiency symptom pattern(KYDS).METHODS:Sixty male Sprague Dawley rats were randomly divided into a control group(n=12)and an experimental group(n=48).Rats in the experimental group were given intramuscular injections of hydrocortisone to establish a KYDS model.The 48 rats successfully modeled were then randomly divided into a model group(model,n=12),a carbenoxolone intraperitoneal injection group(CBX,n=12),a moxibustion group(moxi,n=12),and a moxi+CBX group(n=12).In the moxi,the Shenshu(BL23)and Guanyuan(CV 4)acupoints were treated with moxibustion for 14 d.After treatment,measures were taken of serum levels of corticosterone(CORT),adrenocorticotropic hormone(ACTH),and corticotropinreleasing hormone(CRH).The expression of mineralocorticoid receptors(MRs),glucocorticoid receptors(GRs),11beta-hydroxysteroid dehydrogenase type 1(11β-HSD1),CRH,and ACTH in the rats’amygdala,hypothalamus,or pituitary(as appropriate)was detected.Data were analyzed using one-way analysis of variance.RESULTS:Compared with those of the control group,the serum levels of CRH,ACTH,and CORT;the mRNA and protein expressions of MR,GR,and 11β-HSD1 in the amygdala;the mRNA and protein expressions of 11β-HSD1 in the hypothalamus;the CRH mRNA expression in the amygdala and hypothalamus;and the ACTH mRNA expression in the pituitary of the rats in the model group were all significantly decreased(P<0.05 or 0.01).After treatment with moxibustion,all the aforementioned observation indices except for 11β-HSD1 m RNA expression were ameliorated compared with those in the model group(P<0.05 or 0.01).CONCLUSIONS:Suspended moxibustion can effectively improve the serum levels of ACTH,CRH,and CORT and can up-regulate the mRNA and protein expressions of MR,GR,11β-HSD1,CRH,and ACTH in the amygdala and hypothalamus of KY
