基于红外热成像技术的哮喘慢性持续期患者相关背俞穴体表温度特异性研究

The specificity of body surface temperature of relevant back-shu points in patients with chronic persistent asthma based on infrared thermal imaging technology

目的:通过红外热成像技术检测哮喘慢性持续期患者相关背俞穴的体表温度,观察肺脏病变状态下,相关背俞穴体表温度的特异性变化.方法:选取哮喘慢性持续期患者和健康受试者各45例,分别为观察组和对照组.采用BK-MT02A医用红外热像仪检测两组受试者双侧肺俞、膈俞、脾俞及肾俞穴体表温度.结果:观察组患者双侧肺俞、膈俞、脾俞及肾俞穴体表温度较对照组同侧腧穴体表温度升高(P<0.01,P<0.05);两组受试者双侧肺俞、膈俞穴体表温度高于同侧脾俞、肾俞穴(P<0.01,P<0.05),同侧肺俞与膈俞、脾俞与肾俞之间体表温度比较差异无统计学意义(P>0.05).结论:哮喘慢性持续期患者肺俞、膈俞、脾俞及肾俞穴体表温度病理性升高,说明以上背俞穴具有反映肺脏疾患的特异性;体表温度显著升高的肺俞、膈俞穴,不仅为哮喘慢性持续期患者"本虚标实"的病机提供了客观依据,也体现了相同经络不同腧穴对肺脏疾患反映的差异性.

Objective To detect the body surface temperature of the relevant back-shu points in patients with chronic persistent asthma by infrared thermal imaging technology,and observe the specific changes of the body surface temperature of the relevant back-shu points under the condition of lung disease.Methods Forty-five patients with chronic persistent asthma(observation group)and 45 healthy subjects(control group)were selected.The body surface temperature of bilateral Feishu(BL 13),Geshu(BL 17),Pishu(BL 20)and Shenshu(BL 23)were measured by BK-MT02A medical infrared thermography.Results The body surface temperature of bilateral Feishu(BL 13),Geshu(BL 17),Pishu(BL 20)and Shenshu(BL 23)in the observation group was higher than that in the control group(P<0.01,P<0.05).The body surface temperature of bilateral Feishu(BL 13)and Geshu(BL 17)was higher than that of ipsilateral Pishu(BL 20)and Shenshu(BL 23)in the two groups(P<0.01,P<0.05).There was no statistically significant difference in body surface temperature between ipsilateral Feishu(BL 13)and Geshu(BL 17),between ipsilateral Pishu(BL 20)and Shenshu(BL 23)(P>0.05).Conclusion The pathological increase of body surface temperature of Feishu(BL 13),Geshu(BL 17),Pishu(BL 20)and Shenshu(BL 23)in patients with chronic persistent asthma indicates that above acupoints have specificity in reflecting lung diseases.The Feishu(BL 13)and Geshu(BL 17),which have significantly increased body surface temperature,not only provide objective basis for the pathological pathogenesis of"deficiency in origin and excess in symptom"in patients with chronic persistent asthma,but also reflect the different expressions of different acupoints on the same meridian for the lung diseases.
