应用热层析技术研究面部腧穴代谢强度值的变化情况(英文)

Study on metabolic intensity value changes of points on the face using thermal chromatography technology

目的:通过观察针刺健康人双侧合谷穴前后面部腧穴代谢强度值的变化情况,为研究合谷穴与面口部之间的联系提供一定的科学依据。方法:通过医学热层析成像技术,应用P ennes生物传热理论与模型,从在校大学生中召集45名健康受试者,分别采集针刺双侧合谷穴前后面部红外热层析的图像,观察针刺前健康人面部腧穴代谢强度值的分布特征,以及针刺双侧合谷穴后健康人面部腧穴代谢强度值的变化情况。结果:针刺前,健康人面部腧穴代谢强度值最高的是攒竹,平均值为(0.71±0.23)W,代谢强度值最低的是颧髎;左右同名腧穴代谢强度差值无统计学意义。针刺双侧合谷穴后,健康人面部腧穴代谢强度值以增加为主,其中口禾髎增加最大,平均增加0.35 W;阳白穴增加最小,平均增加0.08 W。结论:健康人面部左右同名腧穴代谢强度值对称性良好;针刺双侧合谷穴后,健康人面部腧穴的代谢强度值较针刺前有所增加,其中以口唇周围增加明显,这与手阳明大肠经在头面部的走形相吻合,为合谷穴与面口部之间的联系提供了一定的科学依据。

Objective： To observe the changes of metabolic intensity value of points on the face before and after needling bilateral Hegu （LI 4） in healthy people and provide scientific basis for association between Hegu （LI 4） and face/mouth. Methods： A total of 45 healthy college students were selected in this study. Using medical thermography and Pennes bio-heat transfer model, the infrared thermograph images on the face before and after needling bilateral Hegu （LI 4） were collected to observe the distribution of metabolic intensity value on the face before acupuncture and changes in these values after needling bilateral Hegu （LI 4）. Results： Before acupuncture, Cuanzhu （BL 2） had the maximal metabolic intensity value. Its mean value was （0.71±0.23） W. Quanliao （SI 28） had the minimal metabolic intensity value. There were no left-right statistical significances in metabolic intensity values. After needling bilateral Hegu （LI 4）, the metabolic intensity values of most points on the face were increased. Kouheliao （LI 19） obtained the maximal increase： 0.35 W on average; and Yangbai （GB 24） obtained the minimal increase： 0.08 W on average. Conclusion： Points on both sides in healthy people have good symmetry in metabolic intensity value. After needling bilateral Hegu （LI 4）, the metabolic intensity values of points on the face were increased, especially points around the lips, which accords with the pathway of the Large Intestine Meridian on the head and face. This provided some scientific foundation for the association between Hegu （LI 4） and face/mouth.
