中文摘要:

目的：研究人体红外热像随时间变化的现象及该现象与气象因素的关系。方法：在冬、春、夏季分别开展3个随机对照试验，试验组服用中药保健品而对照组服用安慰剂或阳性对照药物。所研究中药保健品包括调节免疫功能的生生胶囊、改善睡眠的生安胶囊以及辅助降血脂的生益胶囊。在试验的前36天每6天采集图像1次，每位受试者图象采集的的日时间范围在2h内。对能反映保健品功能的图像特征值随时间的变化以及与气象因素（包括温度，湿度，气压，冷空气过境，热带气旋登陆等）的相关性进行了研究。结果：不同特征显示出不同的随时间变化规律，但试验组与安慰剂对照组同一特征的规律基本一致，保健品的某些长期效果能够在前36天的个别时间点显示。红外热像特征的特殊变化与气象因素密切相关，同时还有其他的影响因素需进一步研究。结论：红外热像是敏感的人体功能显示技术，可反映中药保健品及气象因素对人体的影响，在健康监测上有重要的应用前景。

English Summary:

To study the time-related changes of the infrared thermal images (ITI) of human body and their correlation with meteorological factors. Methods:Three double-blind randomized trials were carried out with placebo or drug control, in winter, spring and summer respectively. Three researched TCM health foods were Shengsheng Capsule (immunity adjustment), Shengan Capsule (sleep improvement) and Shengyi Capsule (decreasing serum lipid). Images were scanned every 6 days during 36-day trial period, with scanning time variation <2h. We explored the correlation between ITI features (indicator of health care effects) and time, and meteorological factors (e.g. temperature, humidity, air pressure, cold front passage and tropical cyclone landing). Results:Each image features demonstrated a respective tendency of time-related variations. However, the trial group and placebo group shared the same variation tendency for each feature, and some long-term effects of health food were reflected in certain time spots within the first 36 days. Some special ITI changes are closely related to meteorological and other factors, which needs further studying. Conclusions:ITI is a sensitive display technology of human body, and by displaying the body's function change under the impact of TCM health foods and meteorological factors, it will have significant application in health monitoring.
