Evaluation of the health status of six volunteers from the Mars 500 project using pulse analysis / 中国结合医学杂志

<p><b>OBJECTIVE</b>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.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>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.</p>

Comparative research on pulse graph and hemorheology of pregnant and pathological slippery pulse / 中华中医药杂志

Objective: To observe the relations between the parameters of pulse graph of pregnant and pathological slippery pulse and the indexes of hemorheology.Methods: The pusle diagram parameters(MSAB,MSBC,HFF',HE/HB and TW) of left guan pulse were extracted by the best extraction method,and the indexes of hemorheology(low shear ?b,high shear ?b,?p,Lb and Hct) were tested.Results: Compared with the control group,MSBC and HFF'of the two slippery pulse groups increased,but HE/HB and TW decreased significantly(P
