摘要: 目的 观察基于转速、时间、震动等因素的多种电动砭术干预方案对机体皮肤红外热成像及血流量的影响,探索电动砭术取效的最佳方案。方法 设计三因素两水平的正交表L8(27),招募80例健康受试者随机分为8组,每组10例,签署知情同意书。受试者进入实验室后,静坐5 min,以适应室内环境,并保持室内温度恒定。在受试者左侧前臂手厥阴心包经的循行路线上标记内关穴、郗门穴。用仪器检测受试者干预前内关穴和郗门穴之间区域的红外热像图及皮肤血流量,并做记录。操作者手持砭钻,沿心包经在左侧前臂循行部位曲泽穴到大陵穴的方向和部位均匀移动,操作过程中给予适度垂直于皮肤的压力,严格按照每组的治疗方案(不同的转速、时间及震动的大小)进行。检测受试者干预后即刻内关穴和郗门穴之间区域的红外热像图及皮肤血流量,并做记录。并记录5 min后、10 min后、15 min后的数据。最后进行统计学处理。结果 ①各组干预后即刻与干预前相比差异显著。红外热像各组均有显著统计学意义(P<0.05),呈现显著变化。血流量变化除第5组、第6组外干预后即刻与干预前相比,均具有显著统计学意义(P<0.05)。②各组在干预后与干预前相比未呈现显著后效应。红外热成像与血流量变化在干预后5 min, 10 min, 15 min与干预前相比均无统计学意义(P>0.05)。③通过正交试验分析,可见各因素对红外热成像的影响程度为因素B(时间)>因素A(转速)>因素C(震动),对血流量的影响程度为因素A(转速)>因素B(时间)>因素C(震动)。方差分析结果显示:因素A(转速)、因素B(时间)是影响红外热成像和血流量的显著性因素,具有统计学差异(P<0.05),其中红外热成像结果显示因素A(转速)(因素B(时间)两水平具有统计学差异(P<0.05)。结论 ①电动砭术对机体红外热成像及皮肤血流量影响的即刻效果显著;②因素A(转速)、因素B(时间)是影响机体温度及皮肤血流量的显著因素;③影响机体温度及皮肤血流量的最佳砭术方案均为高转速(1 800转/min)、长时间(持续2 min)、小震动(震幅约为0.3 cm)。

Abstract: Objective To observe the effects of various electric stone needle intervention programs based on factors such as rotation speed, time, and vibration on the body’s skin infrared thermal imaging and blood flow, and to explore the best solution for electric stone needling. Methods A three-factor two-level orthogonal table L8 (27) was designed, and 80 healthy subjects were randomly assigned to 8 groups, each with informed consent.After the subjects entered the laboratory, they sat quietly for 5 minutes to adapt to the indoor environment and keep the indoor temperature constant.Neiguan(PC6) and Ximen(PC4) points on the route of the pericardium meridian of Hand-jueyin in the left forearm of the subject were marked.An instrument was used to detect the infrared thermal image and skin blood flow of the area between Neiguan(PC6) and Ximen(PC4) points before the intervention of the subjects, and the results were recorded. The operator held the Bianstone drill and moved evenly along the pericardium meridian in the direction and part of the left forearm from Quze(PC3) to Daling(PC7). During the operation, a moderate pressure perpendicular to the skin was applied, and the treatment plan of each group was strictly followed (different rotationspeed, time and vibration).The infrared thermal image and skin blood flow of the area between Neiguan(PC6) and Ximen(PC4) were immediately detected and recorded after the subject’s intervention. And the data were recorded 5 minutes, 10 minutes, and 15 minutes later. Finally, statistical processing was performed. Results ① There were significant differences between groups immediately after intervention and before intervention. All groups of infrared thermal imaging had significant statistical significances (P<0.05). Except for the 5th and 6th groups, the blood flow changes immediately after the intervention were compared with those before the intervention, which were all statistically significant (P<0.05). ② Each group showed no significant after-effects after the intervention, as compared with those before the intervention. Infrared thermal imaging and blood flow changes at 5 minutes, 10 minutes, and 15 minutes after the intervention were not statistically significant, as compared with those before the intervention (P>0.05).③ Through the analysis of the orthogonal experiment, it could be seen that the degree of influence of various factors on infrared thermal imaging was factor B(time)>factor A(rotation speed)>factor C(vibration), and the degree of influence on blood flow was factor A(rotation speed)>factor B(time)>factor C(vibration). The results of analysis of variance showed that factor A (rotation speed) and factor B (time) were significant factors affecting infrared thermal imaging and blood flow, with statistical differences (P<0.05), among which the infrared thermal imaging results showed two levels of factor A(rotation speed)(factor B(time), with statistical differences (P<0.05). Conclusions ① Electric stone needling has a significant immediate effect on the body’s infrared thermal imaging and skin blood flow;② Factor A (rotation speed) and factor B (time) are significant factors affecting the body temperature and skin blood flow;③ The best tone needle programs that affect body temperature and skin blood flow are high speed (1800 rpm), long time (lasting 2 minutes), and small vibration (shock amplitude is about 0.3 cm).
