| Abstract
|
| [Objective] Comparison and analysis of pulse diagnosis information characteristics of individuals with yin deficiency constitution and balanced constitution in healthy populations in Beijing-Tianjin-Hebei and other cities，studying the differences in pulse diagnosis information characteristics between the two groups. [Methods] Using the three-probe traditional Chinese pulse diagnosis instrument，pulse diagnosis information from the cun，guan and chi pulses of 133 individuals with yin deficiency constitution and 153 individuals with balanced constitution were collected，totaling 286 participants. After filtering and noise reduction，12 harmonic fitting models were established for the information，and 193 characteristic parameters were extracted from the pulse diagnosis information of each subject. Unsupervised and supervised learning methods such as principal component analysis，least square estimation，and least absolute shrinkage and selection operator were employed for data feature analysis，improving the decision model for pulse diagnosis information of individuals with yin deficiency constitution in Beijing-Tianjin-Hebei and other cities. [Results] There were significant differences in pulse diagnosis information between the yin deficiency group and the balanced group. The data of the two groups showed significant differences in the first and second principal components in PCA. The accuracy of distinguishing between the two groups using LS and Lasso reached 71% to 75%. The pulse characteristics of individuals with yin deficiency constitution manifested as a decrease in h1 values in all positions except the left chi and right cun，a decrease in s in the right Cuan，and an increase in w values in all positions except the left Cuan. Significant changes in pulse were observed in the frequency domain parameters of both guan and bilateral chi. [Conclusion] There are significant differences in pulse diagnosis information between individuals with yin deficiency constitution and balanced constitution in Beijing-Tianjin-Hebei and other cities，mainly reflected in characteristic parameters such as pulse force（h1），pulse pressure（w），and pulse area（s） at the guan and chi positions. This is consistent with the clinical phenomena of fine pulse in yin deficiency syndrome and string-like pulse in hypertension yin deficiency syndrome. It also provides data support for traditional Chinese medicine（TCM） theories such as “liver and kidney homologous” and “generation between the metal and water”. This also provides objective references for the objective identification of constitution through TCM pulse diagnosis. |
