METHODS: A total of 131 patients with salt-sensitive hypertension were included in the study. Factor analysis and cluster analysis were used to study the characteristics of TCM viscera, syndrome elements and syndrome differentiation. Furthermore, the following parameters were observed and corresponding differences were analyzed, including BMI, waist circumference, abdominal circumference, neck circumference and insulin sensitivity index among group s of different TCM syndrome types. RESULTS: There were 131 cases of saltsensitive hypertension. The results of factor analysis showed that the total variance contribution of F1-5 common factors was 75.8%. According to the pattern differentiation of zang-fu organs, a basic theory of traditional Chinese medicine(TCM), the main zang-fu organs involved in the five common factors are: liver, spleen, and kidney.The main syndrome factors that had been extracted include yin de?ciency, ?re, qi stagnation, yang hyperactivity,dampness, phlegm, qi reversal, heat, retained fluid, essence deficiency, qi descending, qi deficiency, and yang deficiency. Among them, factor 1 accounted for 18.32%, factor 2 accounted for 21.37%, factor 3 accounted for20.43%, factor 4 accounted for 20.61%, and factor 5 accounted for 22.14%. The proportion of zang-fu organs involvement was: 21.37% of the spleen, 17.56% of the kidney, 18.32% of the liver and spleen, and 42.75% of the spleen and kidney. Syndrome elements: yin de?ciency 18.32%, phlegm-dampness 21.37%, qi stagnation 39.69%, qi de?ciency 42.75%, retained ?uid 20.61%, yang de?ciency 60.31%, essence de?ciency 17.56%, qi sinking 17.56%,heat 21.37%, qi reversal 21.37%. Results of cluster analysis: there were 3 categories when the distance variance was 20-Category 1: Factor 1; Category 2: Factor 2; Category 3: Factor 3, Factor 4, Factor 5. Combined with the clinical practice of TCM, the classi?cation based on TCM syndromes was:Category 1, yin de?ciency and yang hyperactivity pattern(accounting for 18.32%); Category 2, excessive accumulation of phlegm-dampness(accounting for 21.37%); Category 3, spleen-kidney yang de?ciency and pattern of water-rheum collecting internally(accounting for 60.31%), including 24 cases of yin-de?ciency and yang-hyperactivity(YDYH), 28 cases of excessive phlegmdampness syndrome(EPDS), 79 cases of spleen and kidney yang-de?ciency and ?uid retention stagnating in the interior(SKFR). There was no difference in the distribution of age and sex among groups. In addition, no signi?cant difference was found regarding BMI, waist circumference, abdominal circumference, neck circumference among groups of salt-sensitive hypertension of different TCM syndrome types. Meanwhile, ISI was signi?cantly lower in cases of spleen and kidney yang-de?ciency and ?uid retention stagnating in the interior than in the other 2 groups,with statistical difference. CONCLUSION: Insulin resistance is the most serious in salt-sensitive hypertension patients with spleen and kidney yang-de?ciency and ?uid retention stagnating in the interior. Besides, obesity is not a critical factor in determining the distribution of TCM syndrome types in patients with salt-sensitive hypertension.展开更多
