Objective: To analyze backShufinger-pressure therapy in treating the patients with outlet obstruction constipation(OOC), the skin temperature changes of conception meridian and governor meridian acupoints in the patients of different patterns before and after treating, and explore the relativity between them. Methods: All 82 patients were divided to heat accumulation of bowel and stomach pattern,Qidepression pattern,Qi deficiency of spleen and stomach pattern, kidney-Yangdeficiency pattern and intestinal dryness due toYin deficiency pattern. The skin temperature of conception meridian and governor meridian acupoints were compared among the normal and the patients of different patterns. Results: Skin temperature of the patients of different patterns changed differently: ①heat accumulation of bowel and stomach pattern: skin temperature of main acupoints distributed on conception meridian in 14 days after treating was decreased compared with before treating significantly (P<0.05); the temperature of main acupoints distributed on governor meridian raised slightly. ②Qidepression pattern: the temperature of main acupoints distributed on conception meridian and governor meridian in seven days after treating was lower compared with before treating evidently(P<0.05), the difference was significant when the temperature in 14 days after treating was compared with before treating(P<0.01). ③Qideficiency of spleen and stomach pattern: skin temperature of main acupoints distributed on conception meridian and governor meridian was changed indistinctly when it was compared among before treating, in seven days and 14 days after treating(P>0.05), but after treating, tracks of both meridians could be seen. ④kidney-Yangdeficiency pattern: compared with before treating, skin temperature of both meridians in seven days after treating was raised significantly(P<0.05), the difference was significant when the temperature in 14 days after treating was compared with before treating (P<0.01). ⑤intestinal dryness due toYindeficiency pattern: compared with before treating, skin temperature of both meridians in seven days after treating was decreased significantly(P<0.05), it was decreased notably in 14 days after treating when it was compared with before treating(P<0.01). Conclusion: ①BackShufinger-pressure therapy could regulate skin temperature of both meridians bidirectionally, it was could lower skin temperature by clearing heat when there is pathogenic heat; it could raise skin temperature by warmingYangand dispelling the cold to stimulate meridianQi when there isYanginsufficiency and cold accumulation in the meridians; it could make nocturnal radiation track more continuous and clear when skin temperature of acupoints is changed indistinctly; it could arouse nocturnal radiation track along the meridian when there is no radiation track. ②BackShufinger-pressure therapy could arouse meridianQiof the bladder, to affect the intersection of meridianQiof conception meridian and governor meridian, therefore to regulate the junctions of lung exterior connected with large intestine, of liver ascending and lung descending, and of spleen ascending and stomach descending, finally, it could achieve the effects of“acupoint-meridian-the improvement of visceral function”.%目的：分析背俞指针疗法治疗出口梗阻型便秘(outlet obstruction constipation，OOC)不同证型患者治疗前后任督二脉主要穴位皮温的变化特点，探讨二者的相关性。方法：将OOC患者82例分为肠胃积热证、气机郁滞证、脾胃气虚证、肾阳虚证、阴虚肠燥证，分析比较各证型及正常人任督二脉穴位皮温情况。结果：不同证型患者任督二脉皮温变化不同：①胃肠积热证：任脉主要穴位皮温治疗第14天与治疗前比较下降明显(P＜0.05)；而督脉主要穴位皮温略微升高。②气机郁滞证：任、督二脉主要穴位皮温治疗第7天与治疗前比较下降明显(P＜0.05)，治疗第14天与治疗前比较差异显著(P＜0.01)。③脾胃气虚证：任督二脉主要穴位皮温治疗前与治疗第7天及第14天比较变化不明显(P＞0.05)，但经治疗后任督二脉经络轨迹明显。④肾阳虚证：任、督二脉主要穴位皮温治疗第7天与治疗前比较升高明显(P＜0.05)，治疗第14天与治疗前比较差异显著(P＜0.01)。⑤阴虚肠燥证：任、督二脉主要穴位皮温治疗第7天与治疗前比较下降明显(P＜0.05)，治疗第14天与治疗前比较下降显著(P＜0.01)。结论：①背俞指针疗法可双向调节任督二脉穴位皮温，在热邪或虚火情况下，可通过泻火或降火的作用，使穴位皮温降低；在阳虚及寒凝经脉时，可通过温阳散寒而激发经络经气，使穴位皮温升高；任督二脉穴位皮温变化不明显者，经治疗后任督二脉红外辐射轨迹变得更加连续、清晰；亦可使没有显示任督经脉红外辐射轨迹者激发出沿该经脉的循经红外辐射轨迹。②通过背俞指针疗法激发膀胱经经气，进而影响任督二脉经气交会，达到调节肺与大肠表里之枢、肝肺升降之枢及脾胃升降之枢的作用，从而起到“穴位-经络-脏腑功能改善”的治疗效应。
