Analysis on Construction of Moisten Pulse Images Based on Wave Intensity Technology
摘要
Abstract
Objective To enrich the objective study of TCM pulse through constructing preliminary moisten pulse images by wave intensity (WI) technology.Methods The study subjects were divided into moisten pulse group (28 cases) and normal pulse group (30 cases). The cunkou pulse conditions were examined by color Doppler ultrasonic diagnostic equipment (ALOKA Prosoundα 10) and wave intensity (WI) pulse images and data were recorded and collected. WI pulse image of moisten pulse and normal pulse were constructed and compared by three-dimensional levels of pressure wave (P wave), blood-flow-velocity wave (U wave), WI wave [the product of blood pressure changes (dP/dt) and blood-flow-velocity changes (dU/dt)], and time. ResultsThe U wave of cunkou moisten pulse based on WI was characterized by a more flat curve, a smaller amplitude and a wider wave than the wave of normal pulse. The slopes of both ascending and descending branches of U wave were lower than those of normal pulse. Dicrotic wavefront (tide wave, h3) of P wave was closed to the main wave (h1) or arrives earlier to make it integrates with the main peak into a large round blunt flat top. Even more h3 was higher than h1, which come into being a notch in the declined branch. Comparing with cunkou pulse, forward compression wave of moisten pulse (W1) was reduced,and its forward expansion wave (W2) increased, and W2 wave appeared at the far from the W1 wave. WI wave displayed an angle-like-shape and its descending branch concave was upward. W1, pre-ejection period (R-1st), ejection time (1st-2nd) and augmentation index (AI) decreased compared with normal pulse (P<0.05), while W2 and pulse wave velocity by WI value deduced (PWV-WI) of moisten pulse increased (P<0.05). After adjusting confounding factors, the mean difference of W1, W2, R-1st, 1st-2nd, AI, and PWV-WI between two groups was still significance (P<0.05).Conclusion Moisten pulse WI pulse image constructed from three-dimensional levels of P wave, U wave, and WI wave can more accurately reflect characteristics of moisten pulse wave and guide TCM clinical pulse diagnosis better.关键词
