目的通过60 d-6°头低位卧床(HDBR)实验模拟航天飞行环境的失重效应、隔离、限制等应激源,研究人体在长期模拟航天飞行环境下的情绪变化规律以及对抗失重影响的不同生理防护措施对受试者情绪的影响。方法21名男性受试者按照生理防护措施的不同,随机分为单纯卧床组、阻抗振动组和中药防护组,每组7人。在卧床前第7天、卧床中每周以及卧床后第7天和后3个月,对3组受试者重复使用焦虑自评量表(SAS)、抑郁自评量表(SDS)和简式心境状态量表(POMS)进行12次心理测验;并在特定的日期采集晨起静脉血样,检测血中皮质醇等与情绪相关的激素含量。使用SPSS17.0统计学软件进行分析,用线图描述各指标的变化趋势,用重复测量方差分析,配对t检验方法对结果进行显著性检验。结果POMS中疲劳分量表以及皮质醇含量在不同时间差异有统计学意义;POMS中的抑郁、精力和自我分量表,以及SAS得分做峰值和谷值的配对t检验有统计学差异;阻抗振动组在POMS紧张分量表分值高于其它两组;线图可以看出卧床期间负性情绪波动从高-低-高-低的变化趋势,皮质醇波动趋势与情绪变化趋势基本一致。结论在60 d-6°头低位卧床模拟的航天飞行环境中,受试者负性情绪变化呈现高-低-高-低的变化趋势,变化的时间点与当前航天飞行中情绪变化的4阶段模型假设基本一致;皮质醇波动和情绪波动趋势基本一致;在卧床期间,阻抗振动组的POMS紧张分量表得分高于其他两组。
Objective To study the emotional changes of human body under long-term simulated space flight environment and different physiology to resist the effects of weightlessness by simulating the weightlessness effect, isolation and restriction of space flight environment by HDBR experiment at 60 d-6 °. Influence of protective measures on the emotion of subjects. Methods Twenty-one male subjects were randomly divided into a single bed rest group, an impedance vibration group and a Chinese herbal protection group according to the different physiological protective measures, with 7 in each group. On the 7th day before bedtime, weekly in bed and 7th day and 3months after bedtime, the anxiety self-rating scale (SAS), self-rating depression scale (SDS) State of mind state scale (POMS) conducted 12 psychological tests; and on the specific day morning venous blood samples were collected to detect blood levels of cortisol and other emotional-related hormones. SPSS17.0 statistical software was used to analyze the trend of each indicator with a line graph, with repeated measures analysis of variance, paired t test method for significant test results. Results There were significant differences in fatigue subscale and cortisol content in POMS at different time points. There were significant differences in depression, energy and self-subscales in POMS and paired t-test between SAS scores and peak-to-valley values. Impedance vibration group In the POMS tension subscale scores were higher than the other two groups; line graph can be seen during bedridden negative emotional fluctuations from high to low - high - low changes in trends, cortisol fluctuations and emotional trends are basically the same. CONCLUSIONS: During the 60d-6 ° head-on-bed simulated space flight environment, the subjects’ negative emotions showed a trend of high-low-high-low. The changing time points were similar to those of the current 4 stages of aerospace flight The model hypotheses were basically the same; the trends of cortisol fluctuations and mood swings were basically the same; during the ambulatory period, the POMS tension subscale scores of the impedance vibration group were higher than the other two groups.
