应用MRI测量针刺缺盆穴安全深度研究

Using MRI to Measure the Safety Depth of Quepen Acupoint

目的：应用磁共振成像（MRI）技术分别测量男性组与女性组针刺缺盆穴的危险深度及安全深度,为临床针灸医师提供数据参考,减少针刺意外发生,提高针刺安全性。方法：选取身体健康BMI指数在18～24之间的在读研究生志愿者40名,其中男性和女性志愿者各20人。使用鱼肝油胶囊标记缺盆穴在体表的位置,并进行MRI扫描,在所获得图像上测量直刺缺盆穴至脏层胸膜深度,以此深度乘以75%为安全深度,对获得的数据应用SPSS17.0进行统计学处理。结果：男性组左侧缺盆穴危险深度为（40.54±5.43）mm,安全深度为（30.41±4.07）mm;右侧缺盆穴危险深度为（41.13±4.98）mm,安全深度为（30.85±3.74）mm。女性组左侧缺盆穴危险深度为（35.18±4.54）mm,安全深度为（26.39±3.41）mm;右侧缺盆穴危险深度为（34.89±4.29）mm,安全深度为（26.17±3.22）mm。左右侧危险深度及安全深度差异性比较P〉0.05。针刺危险深度及安全深度性别差异性比较P〈0.05。表明男性组与女性组各自的左右两侧缺盆穴危险深度、安全深度均无明显差异;男性组与女性组相比危险深度及安全深度存在差异。结论：MRI技术为活体针刺穴位安全深度研究提供了安全、可靠、精确的数据,为临床针刺危险穴位应用提供参考。

Objective： Use Magnetic Resonance Imaging to measure the safety and danger depth of Quepen acupoint from male group and female group,to provide reference data for clinical acupuncturist;to reduce acupuncture accidents and improve acupuncture safety.Methods： Forty healthy volunteer subjects（ 20 men,20 women;the BMI index between 18 ～ 24） participated in this study.Use cod liver oil capsules marked the surface location of Quepen acupoint,and conduct MRI scan,measure the depth from obtaining images of vertical acupuncturing at Quepen acupoint to the visceral pleura,multiplied by 75% as a safety depth.All preprocessing steps were carried out by using SPSS17.0 software.Results： The male group＇s left side danger depth of Quepen acupiont was（ 40.54 ± 5.43） mm and the safety depth was（ 30.41 ± 4.07） mm;the right side danger depth of Quepen acupiont was（ 41.13 ± 4.98） mm and the safety depth was（ 30.85 ± 3.74） mm.The female group＇s left side danger depth of Quepen acupiont was（ 35.18 ± 4.54） mm and the safety depth was（ 26.39 ± 3.41） mm;the right side danger depth of Quepen acupiont was（ 34.89 ± 4.29） mm and the safety depth was（ 26.17 ± 3.22） mm.Both sides of safety and danger depth had difference（ P〈0.05）.Safety and danger depth of different sexes had a significance（ P〈0.05）.In both sides safety depth and danger depth of male group had no significant difference;in both sides safety depth and danger depth of female group had no significant difference;there is a difference of depth and safety depth between male group and female group.Conclusion： MRI technology provides safe,reliable and accurate data of the safety depth for living acupuncture study,providing a reference to clinical application of dangerous points.
