[Analysis on pulse diagram characteristics of subjects with subhealth state].
OBJECTIVE
To study the pulse diagram parameters of subjects with subhealth state and to find the pulse parameters for subhealth state evaluation.


METHODS
A total of 1 275 subjects without diagnosed diseases were recruited and their health conditions were assessed with Health Evaluating Questionnaire H20 V2009. The subjects were assigned to health group or subhealth group according to the scale score. Subjects' syndrome in the subhealth group was differentiated using score of "subhealth state of syndrome differentiation V2010". Another 121 patients with cardiovascular diseases were enrolled as a control. The pulse information was collected with YJJ-101 subhealth pulse monitoring system and the parameters include amplitude of main wave (h₁), amplitude of repeat wave (h₅) and its front wave (h₃), 1/3 or 1/5 width of main wave (w₁) or (w₂), time of rapid ejection phase (t₂), period of pulse (t), pulse pressure (Pp), square (S), area in systole (As) and area in diastole (Ad) of pulse diagram and ratios of h₃/h₁, h₅/h₁, w₁/t, w₂/t and h₁/t₁.


RESULTS
Pulse diagram analysis showed significant differences among health, subhealth and disease group in Pp, h₁, S and As and ratios of h₅/h₁ and w₂/t. Compared with the health group, the values of w₁/t and w₂/t of the subhealth group increased (P<0.05), and Pp, h₁, h₅, h₅/h₁, S, As and Ad decreased (P<0.05). Compared with health group, the parameters of pulse of the subhealth group were increased in Pp and h₅/h₁ (P<0.05) and decreased in h1, w₂/t, S and As (P<0.05). Compared with health group, pulse parameters h₃/h₁, w₁, w₁/t, w₂/t of excess and deficiency syndrome group increased, and h₁, h₅, h₁/t ₁and h₅/h₁ decreased. Among different syndromes of subhealth state, pulse diagram parameters h₁, h₅, h₃/h₁, h₅/h₁ and w₁/t of yin deficiency, qi deficiency, liver stagnation and excess heat group were significantly different (P<0.05) from the health group, for example, pulse parameters h₁ and h₅ of stagnation, yin deficiency, qi deficiency and excess heat group declined in order, and pulse parameters h₃/h₁ and w₁/t of liver stagnation, excess heat, yin deficiency and qi deficiency group increased in order. Pulse index h₁ in the kidney deficiency group was higher than that in the health group and the other syndrome groups.


CONCLUSIONS
Results of analyzing sphygmogram parameters showed different characteristics among different health status and the subhealth state due to different syndromes. Sphygmogram parameters may be used for objective evaluation of health status or subhealth syndrome differentiation.
