项目摘要

Measurement of sleep-wake rhythm was carried out in the surgical patients by actigraphy.Mean sleep time (22:00 to 6:00) of 12 patients was following; 400 min at preoperative day 3(POD 3), 400min at POD 2 and 395 min at preoperative, 367 min at operative day, 307 min at post operative day 1 (POD 1), 284 min at POD2, 290 min at POD 3, 263 min at POD 4, and 282 min at POD 5.Bright light exposure during daytime increases parasympathetic nerve activity during the nighttime.A spectral analysis of heart rate was carried out on 11 young female adults in order to evaluate the effects of bright light exposure on autonomic nervous activity. Bright light was provided by fluorescent lamps during the daytime on day 1. Dim light was given on day 2. The average value during the sleep period was compared following diurnal exposure to bright or dim light. HF component was significantly greater from 23:30 h to 02:00 h after diumal exposure of bright light, being accompanied by lower heart rate during these periods. The results indicate that bright light exposure during the daytime could enhance parasympathetic activity around midnight.Effects of dim or bright-light exposure during the daytime on human gastrointestinal activity.We measured gastrointestinal activity using a breath hydrogen (indicative of carbohydrate malabsorption) and an electrogastrography (EGG, indicative of gastric myoelectric activity) test. Postprandial breath hydrogen excretion during the following nighttime period after daytime exposure to the dim-light condition was significantly higher than under the bright-light condition. The spectrum total power of the EGG recorded after taking the evening meal was significantly lower for the dim than bright-light condition. These results indicate that dim-light exposure during the daytime suppresses the digestion of the evening meal, resulting in malabsorption of dietary carbohydrates in it.
采用体动仪测量手术患者的睡眠-觉醒节律。平均睡眠时间22:00 ~ 6:00随访12例;术前第3天(POD 3)400 min,POD 2 400 min,术前395 min,手术当天367 min,术后第1天(POD 1)307 min,POD 2 284 min,POD 3 290 min,采用心率谱分析方法,研究了白天强光照射对11只成年雌性幼鸟自主神经活动的影响。在第1天的白天,通过荧光灯提供明亮的光。在第2天给予昏暗的光。在睡眠期间的平均值进行比较后,白天暴露于明亮或昏暗的光。白天强光照射后23:30 ~ 02:00 h HF分量显著增加,并伴有心率降低。结果表明,白天明亮的光线照射可以增强午夜前后的副交感神经活动。白天昏暗或明亮的光线照射对人体胃肠活动的影响我们使用呼吸氢(表明碳水化合物吸收不良)和胃电图(EGG,表明胃肌电活动)测试来测量胃肠活动。餐后呼吸氢排泄在接下来的夜间期间白天暴露于昏暗的光条件下显着高于在明亮的光条件下。吃晚饭后记录的EGG的光谱总功率在昏暗的光线条件下显著低于在明亮的光线条件下。这些结果表明,在白天昏暗的光线照射抑制消化的晚餐,导致吸收不良的膳食碳水化合物在它。
