摘要

To comprehensively evaluate the health status of 6 volunteers from the Mars 500 Project through analyzing their pulse graphs and determining the changes in cardiovascular function

degree of fatigue and autonomic nervous function. Six volunteers were recruited; all were male aged 26–38 years (average 31.83±4.96 years). Characteristic parameters reflflecting the status of cardiovascular functions were extracted

which included left ventricular contraction

vascular elasticity and peripheral resistance. The degree of fatigue was determined depending on the difference between the calendar age and biological age

which was calculated through the analysis of blood pressure value and characteristic parameters. Based on the values of pulse height variation and pulse time variation on a 30-s pulse graph

autonomic nervous function was evaluated. All parameters examined were marked on an equilateral polygon to form an irregular polygon of the actual fifigure

then health status was evaluated based on the coverage area of the actual fifigure. The results demonstrated: (1) volunteers developed weakened pulse power

increased vascular tension and peripheral resistance

and slight decreased ventricular systolic function; (2) the degree of fatigue was basically mild or moderate; and (3) autonomic nervous function was excited but generally balanced. These volunteers were in the state of sub-health. According to Chinese medicine theories

such symptoms are mainly caused by the weakening of healthy qi

Gan (Liver) failing in free coursing

and disharmony between Gan and Wei (Stomach)

which manifests as a weak and string-like pulse.
