摘要
目的:基于红外热成像技术探究原发性痛经寒凝血瘀证患者小肠经相关经穴的热学特性,以及艾灸关元穴对其热学特性的影响.方法:选取原发性痛经寒凝血瘀证患者21例(痛经组)及正常女性21名(正常组).在月经来潮的第1～3天,采用红外热成像仪检测两组受试者小肠经相关经穴(腕骨、养老、小海、肩贞、臑俞、关元)的红外辐射温度,比较两组的红外温度变化;痛经组在关元穴进行单次30 min的艾灸治疗,比较艾灸前后痛经组患者小肠经相关经穴的温度变化及腹痛视觉模拟评分法(VAS)评分.结果:与正常组比较,痛经组患者关元、双侧养老、左侧小海、左侧肩贞、双侧臑俞红外温度均降低(P＜0.05);与艾灸前比较,痛经组患者艾灸后腹痛VAS分值降低(P＜0.05),痛经组患者关元、双侧腕骨、养老、小海、肩贞、臑俞红外温度增高(P＜0.05).结论:原发性痛经寒凝血瘀证患者小肠经穴位的红外温度低于正常女性,验证了小肠经与胞宫的特异性联系.原发性痛经寒凝血瘀证患者艾灸后肠经穴位温度显著升高,提示小肠经温度升高可能是艾灸关元穴疗效的经络效应机制之一.
Abstract
Objective:To explore the thermal characteristics of related acupoints of small intestine meridian in patients with primary dysmenorrhea(PD)of cold coagulation and blood stasis syndrome based on infrared thermal imaging technology,and the effect of moxibustion at Guanyuan(RN 4).Methods:A total of 21 patients with primary dysmenorrhea and cold coagulation stasis syndrome(PD group)and 21 normal females(normal group)were selected.On the 1st to 3rd day of menstruation,infrared thermography was used to detect the infrared radiation temperature of the small intestine meridian related acupoints[Wangu(SI 4),Yanglao(SI 6),Xiaohai(SI 8),Jianzhen(SI 9),Naoshu(SI 10),Guanyuan(RN 4)]in two groups of subjects,and the changes in infrared temperature between the two groups were compared.The DP group received a single 30 minute moxibustion treatment at Guanyuan,and the temperature changes and abdominal pain visual analog scale(VAS)scores of the small intestine meridian related acupoints in the dysmenorrhea group before and after moxibustion were compared.Results:Compared with the normal group,the infrared temperature of Guanyuan(RN 4),bilateral Yanglao(SI 6),left Xiaohai(SI 8),left Jianzhen(SI 9)and bilateral Naoshu(SI 10)in the DP group decreased(P＜0.05).Compared with before moxibustion,the VAS score of abdominal pain in the DP group decreased after moxibustion(P＜0.05),and the infrared temperature of Gunyuan(RN 4),bilateral Wangu(SI 4),Yanglao(SI 6),Xiaohai(SI 8),Jianzhen(SI 9)and Naoshu(SI 10)in the DP group increased(P＜0.05).Conclusion:The infrared temperature of acupoints in the small intestine meridian of patients with primary dysmenorrhea of cold coagulation and blood stasis syndrome is lower than that of normal women,which verifies the specific relationship between the small intestine meridian and the uterus.The temperature of intestinal meridian points in patients with primary dysmenorrhea of cold coagulation and blood stasis syndrome increased significantly after moxibustion,suggesting that the increase of intestinal meridian temperature may be one of the meridian effect mechanisms of moxibustion at Guanyuan(RN4).
