基于磁共振成像观察穴位埋线对单纯性肥胖患者经穴刺激效应的时效特点
MRI-based observation of the time-effect features of the stimulating effect of cat-gut embedding on meridian points in patients with simple obesity
摘要
Abstract
Objective To observe the time-effect features of the stimulating effect of cat-gut embedding on topical meridian points[Tianshu(ST25),Pishu(BL20),and Fenglong(ST40)]in patients with simple obesity using magnetic resonance imaging(MRI).Method T2-mapping technique was used to collect fat-suppression T2WI images and T2-mapping 8 echo image sequences from 15 subjects with simple obesity at different time points before and after cat-gut embedding at the left Tianshu,Pishu,and Fenglong.The images were sent to a post-processing workstation to generate artificial color maps.Three consecutive levels with the strongest signals were selected to obtain the mean T2 value of their region of interest(ROI).The changing tendencies of the signal intensity and T2 value of Tianshu,Pishu,and Fenglong on fat-suppression T2WI image sequence were analyzed.Result On days 1 and 4 after cat-gut embedding,the T2 value of ROI at Tianshu increased significantly compared with that before embedding(P＜0.05),and high-intensity signals were found;compared with day 4 after cat-gut embedding;the T2 value of ROI dropped notably at weeks 1,2,3,4,and 5 after cat-gut embedding(P＜0.05),and the signal intensity at these time points approached that before embedding.The T2 value of ROI at Pishu on days 1 and 4 and at week 1 after cat-gut embedding was significantly higher than that before embedding(P＜0.05),and high-intensity signals were found;the T2 value of ROI dropped at weeks 2,3,4,and 5 after cat-gut embedding compared with that at week 1 after embedding(P＜0.05),and the signal intensity at these time points approached that before embedding.The T2 value of ROI at Fenglong on days 1 and 4 and at weeks 1 and 2 after cat-gut embedding was significantly higher than that before embedding(P＜0.05),and high-intensity signals were found;the T2 value of ROI dropped at weeks 3,4,and 5 after cat-gut embedding compared with that at weeks 1 and 2 after embedding(P＜0.05),and the signal intensity at these time points approached that before embedding.Conclusion The stimulating effect of cat-gut embedding at different points shows various time-effect features in simple obesity patients;the effect lasts about 1 week at Tianshu,2 weeks at Pishu,and 3 weeks at Fenglong.Hence,a periodic treatment plan can be established when using cat-gut embedding to treat simple obesity:1 weeks for the abdomen region,2 weeks for the back,and 3 weeks for the lower limbs.关键词
