摘　　要：Objective:To observe the effects of moxibustion at different temperatures(38℃,46℃)on blood lipids,endothelial morphology of the thoracic aorta,serum endothelin-1(ET-1),calcitonin gene-related peptide(CGRP),nitric oxide(NO),and endothelial NO synthase(eNOS)in hyperlipidemic rats.Methods:Using the random number table method,60 Sprague Dawley rats were randomly and evenly divided into blank,model,38℃-moxibustion,and 46℃-moxibustion groups.Rats in the 3 experimental groups were fed a high-fat feed to model hyperlipidemia in rats.Rats in the 38℃-moxibustion and 46℃-moxibustion groups were moxibustion on the Shenque and bilateral Zusanli acupoints for 10 minutes each,once every other day for 4 weeks,at temperatures of 38±1℃ and 46±1℃.After that,rat blood samples were collected to detect blood lipids and ET-1,CGRP,eNOS and NO.Take the endotheal tissue of the thoracic aorta to do HE staining.Results:(1)The serum total cholesterol,triglycerides,and low-density lipoprotein cholesterol of rats in the 46℃-moxibustion group were significantly lower than those in the model and 38℃-moxibustion groups.(2)Revealed by hematoxylin and eosin staining,showed necrosis in the local vascular endothelial cells and mild inflammatory cell infiltration in the tunica adventitia of the hyperlipidemic rats.These endothelial morphologies did not improve significantly after moxibustion at 38℃ but did improve at 46℃.(3)Compared with the blank group,serum ET-1 was significantly higher and serum CGRP,NO,eNOS were significantly lower in the model group.Compared with the model and the 38℃-moxibustion groups,serum ET-1 was significantly lower and serum CGRP,NO,eNOS were significantly higher in 46℃-moxibustion groups.Conclusion:Moxibustion at 46℃ effectively regulated blood lipids,improved the morphology of the vascular endothelium,and protected vascular endothelial function.
