摘要
目的基于磁共振成像观察穴位埋线对单纯性肥胖患者局部经穴(天枢、脾俞、丰隆)刺激效应的时效特点。方法应用T2-mapping技术采集15例单纯性肥胖患者左侧天枢、脾俞、丰隆穴埋线前后不同时间段T2WI压脂及T2-mapping 8回波序列图像,传入后处理工作站生成伪彩图,获取信号最强的连续3个层面感兴趣区(region of interest,ROI)的T2值均数,分析天枢、脾俞、丰隆穴局部T2WI压脂序列图像的信号影强弱和T2值随时间变化的特点。结果天枢穴埋线后1、4 d ROI的T2值均较埋线前显著升高(P<0.05),均可见不同高信号影;埋线后1、2、3、4、5周ROI的T2值较埋线后4d显著下降(P<0.05),各时间段信号影接近埋线前。脾俞穴埋线后1、4 d及埋线后1周ROI的T2值均较埋线前显著升高(P<0.05),均可见不同高信号影;埋线后2、3、4、5周ROI的T2值较埋线后1周显著下降(P<0.05),各时间段信号影接近埋线前。丰隆穴埋线后1、4 d及埋线后1、2周ROI的T2值均较埋线前显著升高(P<0.05),均可见不同高信号影;埋线后3、4、5周ROI的T2值较埋线后2周显著下降(P<0.05),各时间段信号影接近埋线前。结论单纯性肥胖患者埋线后穴位刺激效应具有不同的时效特点,天枢约1周,脾俞约2周,丰隆约3周。故单纯性肥胖患者埋线减肥时,建议可参照腹部1周、背部2周、下肢3周的间隔周期治疗。
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.
