| Objective:The study group found in a small sample study in the early stage[1]that there are certain differences in the biophysical characteristics of different meridian points in the same spinal cord segment of the viscera.It is presumed that the basis of the acupunctures response function is the same spinal cord segment as the viscera.However,its specific performance should be related to the meridian and attributes of the acupoints.Therefore,based on the previous studies,this topic further uses infrared thermal imaging technology to observe and analyze the performance of different meridians and different types of acupoint thermal characteristics in primary dysmenorrhea with the same or adjacent spinal segments,and summarizes the rules of the response to viscera function.To explore the specificity of primary dysmenorrhea in infrared thermography.It lays the foundation for studying the mechanism of temperature difference response in the acupoints and enriches the function specificity theory of the acupoints in order to provide a scientific and reliable basis for the selection of acupoints for clinical treatment of this disease.Methods:This study calculated the sample size by pre-test and should include 104 subjects.When the ratio of dysmenorrhea subjects（dysmenorrhea group）and normal subjects（normal group）was 1:1,there were 52 cases in each group.Due to taking into account the subject’s loss during the test,estimated 15%of the rate of loss,it was included in the total of 122 subjects,dysmenorrhea group and the normal group of 61 cases,but in the course of the test to remove and suspend 7 cases,Finally,115 subjects were actually included in the study,including 58 cases of dysmenorrhea group and 57 cases of normal group.All subjects were selected strictly in accordance with the inclusion criteria and exclusion criteria,and all were from female students and graduate students of Hebei College of Traditional Chinese Medicine from May2016 to May 2017.Tested at Hebei University of Chinese Medicine Scientific Research Center.The detection points are the same with the uterus or adjacent spinal segments related to uterus meridians:the Taibai points of the Yuan-Source points,the Diji points of the Xi-Cleft,the Sanyinjiao points of the crossing points and the Xuehai points of the non-specific acupoints of spleen channel of the Foot-Taiyin;Zhongdu point;the Taichong points of the Yuan-Source points and the Zhongdu points of the Xi-Cleft of liver channel of the Foot-Jueyin;Taixi points of Yuan-Source points and Shuiquan points of Xi-Cleft of kidney channel of the Foot-Shaoyin;Xuanzhong points of mon-relatedmeridiansaupointsofgallbladderchannelofthe Foot-Shaoyang;Non-acupoints points in the same level ofXuanzhong and Sanyinjiao,between stomach channel of the Foot-Yangming with gallbladder channel of the Foot-Shaoyang.A long-wave non-refrigerated portable thermal imaging camera manufactured in Germany was used.It is applied to two groups of subjects 1 to 3 days before the menstruation（later referred to as before the menstruation）,on the first day of menstruation,and on the third day after the end of menstruation.The subjects were exposed to the test site for 15minutes in a quiet state,and the seat was selected during exploration.Each acupoint was detected for 15 minutes.The temperature difference of the same name points was the main outcome measure of thermal characteristics,and the infrared thermal image was used as an objective picture.The time of three probes per subject remained the same.At the same time,the indoor and outdoor temperature and humidity were recorded and correlated with the body surface temperature difference.Result:1 Baseline informationThere was no significant difference in age,menarche age,menstrual cycle,and body temperature between the dysmenorrhea group and the normal group（P>0.05）.2 Correlation analysis of body surface temperature difference and indoor and outdoor environment at different time in two groups2.1 The analysis of the correlation between body surface temperature difference and indoor and outdoor environments at different points of time in the dysmenorrhea group2.1.1 Indoor temperature:Before the menstruation,the the body surface temperature difference of Xuanzhong points was related to low indoor temperature（r=-0.311,P<0.05）.There was no significant correlation between the remaining points（P>0.05）.2.1.2 Indoor Humidity:Before the menstruation,the the body surface temperature difference of Shuiquan points was related to low indoor humidity（r=-0.385,P<0.05）.There was no significant correlation between the remaining points（P>0.05）.2.1.3 Outdoor temperature:The third day after the menstruation,the body surface temperature difference of the Diji points was related to the low indoor humidity（r=0.306,P<0.05）.There was no significant correlation between the remaining points（P>0.05）.2.1.4 Outdoor humidity:There is no significant correlation between the body surface temperature difference of the same name acupunctures and the outdoor humidity before the menstruation,on the first day of menstruation,and on the third day after menstruation（P>0.05）.2.2 The analysis of the correlation between body surface temperature difference and indoor and outdoor environments at different points of time in the normal group.2.2.1 Indoor temperature:There is no significant correlation between the body surface temperature difference of the same name acupunctures and the indoor temperature before the menstruation,on the first day of menstruation,and on the third day after menstruation（P>0.05）.2.2.2 Indoor Humidity:Before the menstruation,the body surface temperature difference of the Taibai points was related to the low indoor humidity（r=-0.312,P<0.05）.There was no significant correlation between the remaining points（P>0.05）;on the third day after menstruation,the body surface temperature difference of the Diji points was related to the low indoor humidity（r=-0.310;P<0.05）.There was no significant correlation between the remaining points（P>0.05）.2.2.3 Outdoor temperature:There is no significant correlation between the body surface temperature difference of the same name acupunctures and the outdoor temperature before the menstruation,on the first day of menstruation,and on the third day after menstruation（P>0.05）.2.2.4 Outdoor Humidity:on the first day of menstruation,the body surface temperature difference of the Taichong points was related to the low outdoor humidity（r=0.310;P<0.05）.There was no significant correlation between the remaining points（P>0.05）.3 points of surface temperature difference comparison results.3.1 The surface temperature difference
