摘　　要：目的探索电针调节人体节律的相位反应规律。方法通过监测人体体核温度,在低体温点前后不同时刻点电针、光照肌部位,用放免法检测血浆可的松激素含量并进行节律统计分析。结果(1)军人血浆可的松表现出明显的近似昼夜节律;(2)在低体温点前3时行电针、光照,可引起可的松节律相位滞后;在低体温点后3时行电针、光照引起可的松节律相位超前;其他时刻点刺激,可的松节律的相位无显著性改变。结论电针、光照肌可调节对军人血浆中的可的松激素节律相位,但具有明显的依时相性,其相位反应曲线呈光性模式。Objective To observe the effects of electric stimulation on the circadian rhythm of plasma cortisone in soldiers. Methods Electric stimulation or phototherapy was respectively performed in the popliteal region (behind the knee) of the sol-diers at different time points and radio immunal assay was utilized to examine the plasma cortisone concentration. Results The plasma cortisone concentration exhibited obvious circadian rhythmicity. At the 3 time points before the lowest core tem-perature occurred, treatments with electric stimulation or phototherapy resulted in delayed phase of circadian cortisone rhythm, while the same treatments given at the 3 time points after the lowest core temperature caused earlier arrival of the phase. No changes in the rhythm phase in response to treatments at other time points. Conclusion Both of electric stimulation and phototherapy can adjust the phase of the cortisol circadian rhythmicity, and the phase curve displayed photic response to the treatments.
