Background. Deqi sensation is a complex but an important component for acupuncture effect. In this study, we tried to observe the relationship between Deqi and skin temperature changes and whether there was some relativity between Deqi and needle stimulations on cold congealing and dysmenorrhea rat model. Thirty-two female Sprague Dawley (SD) rats were randomly divided into four groups (Saline Control Group, Model Group, Group A with strong stimulation, and Group B with small stimulation). Group A and Group B were performed with different stimulations. We found that, compared with saline control group, model group, and Group B, Group A showed that the skin temperature changes on right acupoint SP6 and SP10 increased significantly at 5 min-10 min interval. The skin temperature changes on left SP6 decreased at instant-5 min interval. The skin temperature changes on right SP10 decreased significantly at instant-5 min interval and 10 min-20 min interval. Thermogenic action along Spleen Meridian of Foot Greater Yin was manifested as simultaneous skin temperature increase on right SP6 and SP10 at 5 min-10 min interval after needling SP6, which was helpful to illustrate the relationship between the characteristic of Deqi and needle stimulations.
得气感是针灸疗效的一个重要组成部分，虽然复杂，但却非常关键。在本研究中，我们尝试观察得气感与皮肤温度变化之间的关系，以及得气感与针刺对寒凝血瘀型痛经大鼠模型的刺激之间是否存在一定的相关性。
将 32 只雌性 Sprague Dawley（SD）大鼠随机分为四组（生理盐水对照组、模型组、强刺激组 A 和弱刺激组 B）。对组 A 和组 B 进行不同的刺激。我们发现，与生理盐水对照组、模型组和组 B 相比，组 A 表现出右穴 SP6 和 SP10 的皮肤温度变化在 5-10 分钟间隔内明显增加。左 SP6 的皮肤温度变化在即刻-5 分钟间隔内下降。右 SP10 的皮肤温度变化在即刻-5 分钟间隔和 10-20 分钟间隔内显著下降。足太阴脾经的热敏化作用表现为针刺 SP6 后 5-10 分钟间隔内右 SP6 和 SP10 同时皮肤温度升高，这有助于说明得气感的特征与针刺刺激之间的关系。
得气感与皮肤温度变化之间存在一定的相关性，这可能与针刺刺激的强度和类型有关。
