Objective: To find out the serum metabolic markers of Youguiwan (YGP) in the treatment of kidney-Yang deficiency syndrome (KYDS)
and to further explore the regulatory role of medicinal herbs (the Yang-tonifying herbs
the Yin-tonifying herbs and the blood-tonifying herbs) with different properties in YGP on the metabolic markers. Method: We used proton hydrogen nuclear magnetic resonance spectroscopy (1H-NMR) to study on the serum metabonomics of KYDS rats treated by YGP
and combined with pattern recognition to analyze the changes of serum metabolites
thereby finding the metabolic markers of YGP in the treatment of KYDS. At the same time
a mathematical model was established by support vector regression (SVR) to analyze and predict the influence of dose changes of medicinal herbs with different properties in YGP on the metabolic markers.Further exploration of which metabolites were regulated by medicinal herbs with different properties in YGP
and the mechanism of action of YGP was preliminary investigated. Result: Twenty-two metabolic markers were identified
including amino acid metabolism (leucine
valine
arginine
alanine
methionine
glutamate
glutamine
threonine
tyrosine and taurine)
glucose metabolism (lactate
acetate and β-glucose)
energy metabolism (glycerol
creatine and myo-inositol)
gut metabolism[betaine/trimetlylamine oxide (TMAO)]
lipid metabolism[very-low density lipoprotein (VLDL)
low-density lipoprotein (LDL) and high-density lipoprotein (HDL)] and glycoprotein[N-acetyl glucoside (NAG)].Furthermore
using SVR analysis and prediction
we found that the Yang-tonifying herbs mainly acted on HDL and betaine/TMAO;the Yin-tonifying herbs primarily acted on LDL/VLDL
NAG and leucine;while the blood-tonifying herbs chiefly played a role in creatine
glutamate
lactic acid
methionine
myo-inositol and glycerol. Conclusion: The serum metabonomics based on 1H-NMR can find metabolic markers of KYDS
and the mechanism of action of KYDS regulated by medicinal herbs with different properties in YGP can be further revealed by integrating with SVR.
