| Object:Based on infrared thermal imaging technology,research on Diabetic peripheral neuropathy(Diabetic peripheral neuropathy,DPN)in patients with infrared thermal images,and explore the different TCM syndrome types DPN patients in different areas,the average temperature of the infrared thermal image of acupoints,so as to the diagnosis and differential diagnosis of DPN provide visualization of the objective basis of TCM syndrome differentiation.Methods:A total of 100 DPN patients who met the inclusion criteria(the observation group)were collected for TCM syndrome differentiation,and 100 healthy subjects(the control group)were collected.Both groups underwent infrared thermal imaging examination.In the collected infrared thermal map,the infrared thermal image characteristics of the two groups of subjects were firstly observed and summarized,and then the infrared average temperature value of the observation site was derived.All the data were input into Excel,and the statistical software SPSS 26.0 was used for statistical analysis.Results:1.Infrared thermal imaging of the limbs between the two groups:In the observation group,there were many abnormal thermal structures of limbs,which showed as follows :(1)cold deviation of limbs;(2)All limbs showed thermal deviation;(3)the palm is often heat deviation.The heat source distribution on the left and right sides is symmetrical,accompanied by discontinuous heat source,thermal structure disorder,spotty,agglomerate high temperature area.In the control group,the temperature of each limb region was uniform and consistent,and the transition between high temperature zone and low temperature zone was natural.There was no obvious point-like,lumpy high temperature zone,no obvious cold-heat staggered structure,and the thermal structure on the left and right sides was basically symmetrical.2.Comparison of infrared average temperature values between the two groups:(1)Extremities: the palm temperature of observation group was higher than that of control group(P < 0.05);(2)Liver and kidney area: the temperature of both kidney area in the observation group was lower than that in the control group(P < 0.05),and there was no statistical difference in the temperature of liver area;(3)meridians and acupoints: the temperatures of left Shenshu and right Shenshu in the observation group were lower than those in the control group(P<0.05).3.Comparison of infrared average temperature values among syndromes in the observation group:3.1 Comparison of average infrared temperature of DPN in Yang-deficiency and cold-condense type:(1)Limbs: the temperature in front of upper arm,back of upper arm,front of forearm,front of thigh,back of thigh and dorsum of foot on both sides was lower than that in the control group(P < 0.05);(2)Liver and kidney area: the temperature of bilateral kidney area was lower than that of control group(P < 0.05),and there was no statistical difference in the temperature of liver area;(3)meridians and acupoints: Du vein,Ren vein,bilateral Ganshu,bilateral Pishu and bilateral Shenshu were lower than those in the control group(P < 0.05).3.2 Comparison of average infrared temperature of DPN in liver and kidney deficiency type:(1)Temperatures of limbs: palms were higher than those of control group(P < 0.05);(2)Liver and kidney region: the temperature of liver region was higher than that of control group(P < 0.05),and the temperature of kidney region was lower than that of control group(P < 0.05);(3)meridians and acupoints: the temperature of bilateral Ganshu and Shenshu was lower than that of the control group(P < 0.05).3.3 Comparison of average infrared temperature of DPN with Yin deficiency and blood stasis:(1)Temperatures of limbs: in front of upper arm,front of forearm,palm,front of thigh,back of thigh,front of calf,back of calf and back of foot were all higher than those of control group(P < 0.05);(2)There was no statistical difference in liver and kidney area(P>0.05).(3)meridians and acupoints: the temperature of du mai,ren mai and shuangfei shu was higher than that of the control group(P<0.05).3.4 Comparison of average infrared temperature of DPN in the type of Qi deficiency and blood stasis:(1)There was no statistical difference in limbs(P > 0.05);There was no significant difference in liver and kidney area(P > 0.05).Meridians and acupoints:compared with the control group,the temperature of bilateral Feishu and Pishu were lower(P<0.05).Conclusions:1.The infrared characteristics of the thermal structure of the limbs of diabetic peripheral neuropathy patients and healthy people are different,and the infrared temperature data of the two in different areas and acupoints are statistically different,indicating that the infrared thermal imaging has guiding significance for the diagnosis of DPN.2.The infrared temperature in different areas and acupoints in patients with different TCM syndromes of diabetic peripheral neuropathy has characteristic manifestations,which indicates that infrared thermal imaging technology has guiding significance for TCM syndrome differentiation of DPN and can provide objective basis for syndrome differentiation and classification of DPN. |
