基于红外热像技术观察穴位贴敷对阳虚质人群督脉皮温影响

Infrared Thermography-based Observation of the Effect of Acupoint Application on the Skin Temperature of the Du Meridian in People with Yang Deficiency Constitution

目的观察穴位贴敷对阳虚质人群督脉皮温的影响。方法将78例阳虚质的受试者随机分为治疗组40例和对照组38例。治疗组采用自拟阳虚方贴敷干预,对照组采用自制安慰剂贴敷干预。观察两组干预前后阳虚体质量表积分、督脉腧穴(身柱、至阳、脊中、腰阳关)及督脉平均红外皮温变化,并比较两组的临床疗效。结果治疗组治疗后阳虚体质量表积分较治疗前降低,且下降幅度大于对照组;治疗组各检测穴区督脉腧穴(身柱、至阳、脊中、腰阳关)及督脉平均红外皮温均较治疗前上升,且升高幅度大于对照组;差异有统计学意义(P<0.05)。治疗组体质量表积分总有效率、督脉腧穴及督脉平均红外皮温总有效率优于对照组(P<0.05)。结论穴位贴敷干预可以改善阳虚质,提高督脉区域温度。红外热成像技术能可视化地分析干预前后督脉温度变化,可以作为中医量化评估工具。

Objective To observe the effect of acupoint application on the skin temperature of the Du Meridian in people with yang deficiency constitution.Method Seventy-eight subjects with yang deficiency constitution were randomized to a treatment group(40 cases)and a control group(38 cases).The treatment group received acupoint application of self-made Yang-deficiency prescription and the control group,acupoint application of self-made placebo.The Yang-deficiency constitution scale score was recorded and the infrared skin temperatures of Du Meridian points(Shenzhu,Zhiyang,Jizhong and Yaoyangguan)and the average infrared skin temperature of the Du Meridian was measured in the two groups before and after treatment.The clinical therapeutic effects were compared between the two groups.Result After treatment,the Yang-deficiency constitution scale score decreased in the two groups compared with before and the decline range was larger in the treatment group than in the control group;the infrared skin temperatures of Du Meridian points(Shenzhu,Zhiyang,Jizhong and Yaoyangguan)in the detection areas and the average infrared skin temperature of the Du Meridian increased in the treatment group compared with before and the increase range was larger than in the control group with a statistically significant difference(P<0.05).The total efficacy rates in the Yang-deficiency constitution scale score and in the infrared skin temperatures of Du Meridian points and the average infrared skin temperature of the Du Meridian were better in the treatment group than in the control group(P<0.05).Conclusion Acupoint application can improve yang deficiency constitution and increase the temperature of the Du Meridian area.Infrared thermography can visually analyze pre-/post-intervention change of Du Meridian temperature and be used as a quantitative evaluation tool of traditional Chinese medicine.
