Abstract | OBJECTIVE: To study the development mechanism of kidney- Yang deficiency through the establishment of support vector machine models of relevant hormones of the pituitary-target gland axes in rats with kidney- Yang deficiency syndrome. METHODS: RESULTS: The feedback control action of the pituitary-adrenal axis began to lose efficacy from the middle stage of kidney- Yang deficiency. The contents all hormones of the three pituitary-target gland axes decreased in the advanced stage. Relative errors of the jackknife test of the SVR models all were less than 10%. CONCLUSION: Imbalances in mutual regulation among the hormones of the pituitary-target gland axes, especially loss of effectiveness of the pituitary-adrenal axis, is one pathogenesis of kidney- Yang deficiency. The SVR model can accurately reflect the complicated non-linear relationships among pituitary-target gland axes in rats with of kidney- Yang deficiency.
