摘要
目的:考察拔罐时压力因素、时间因素及双因素的交互作用对罐斑颜色变化的影响,为拔罐参数及效应研究提供依据。方法:采用正交试验设计,时间3水平,压力4水平,共12个刺激参数,在同一健康受试者背部12个部位进行拔罐,一共完成34人次的试验。应用制作的罐斑颜色图谱,对拔罐24h后的罐斑颜色进行评分,分析罐斑的变化规律。结果:用正交试验设计的方差分析,不同参数的整体差异有统计学意义(P<0.01)。时间因素对罐斑颜色的影响有统计学意义(P<0.05),呈现10min>30min>20min。压力因素对罐斑颜色的影响差异有统计学意义(P<0.01),呈现-0.07MPa>-0.06MPa>-0.05MPa>-0.04MPa。结论:10min×-0.04MPa即能使拔罐部位产生明显瘀斑,随着刺激量增强罐斑越来越重;压力因素对罐斑的影响最大,呈线性关系,可表达为:Y(罐斑颜色)=2.025+0.902×100×负压绝对值(-MPa);时间因素对罐斑的影响较为复杂,可能与拔罐部位有关。
Objective To investigate the effects of the factors of time and pressure during cupping treatment on the cupping mark color, so as to provide scientific data and evidence for study on parameters and effect of cupping treatment. Methods Orthogonal experimental design was used with 12 stimulating parameters on 3 time levels and 4 pressure levels, cupping was given at 12 sites on the back of a same healthy subject, and 34 persons/times were completed in the experiment. The cupping mark color at each site was assessed 24 hours after cupping with a cupping mark color atlas, and the change law of cupping mark color was analyzed. Results There was a significant difference for the different parameters （P〈0.01）. The time factor had statistically significant effect on cupping mark color （P〈0. 05）, showing 10 min2〉30 min〉20 min. The effect of pressure factor on cupping mark color was sig nificant （P〈0.01）, showing -0.07 MPa〉-0.06 MPa〉-0.05 MPa〉 -0.04 MPa. Conclusion The stimulation of 10 minutes and the pressure of -0.04 MPa produces a marked ecchymosis on the cupping site, getting dar ker and darker along with increase of the stimulation intensity; the effect of pressure factor on cupping mark color is the largest with a linear relationship, which can be expressed as Y （cupping skin color）= 2. 025＋0. 902 × 100 × negative pressure absolute value （- MPa）; while the effect of time factor on cupping mark color is more complicated, which is possibly related with the cupping site.
