| Objectives:to study the syndromes of yang deficiency and yin deficiency, and the constitutions of yang deficiency and yin deficiency in Chinese medicine, summarize the research progress and achievements, and further enrich the relationship between constitutions and syndromes; to compare the characteristics between syndromes of spleen and stomach yang deficiency and stomach yin deficiency, and the metabonomics of the constitutions of yang deficiency and yin deficiency, to explore the evidence of the classification of syndromes and constitutions and its mechanism; to provide the molecular biological evidence for the relationship between constitutions and syndromes.Methods:The theory of both the syndromes and constitutions of yang deficiency were studied via methods of literature searching and modern literature analysis. In order to find the biomarker, the characteristics of the metabonomics of the blood and urine in the syndromes of spleen and stomach yang deficiency and stomach yin deficiency and the constitutions of yang deficiency and yin deficiency were compared and analyzed by the technique of 1H-NMR and the Superconducting NMR spectrometer of INOVA 600 MHz (Varian,Inc.)Results:The characteristics of the metabonomics in the syndromes of spleen and stomach yang deficiency and stomach yin deficiency and the constitutions of yang deficiency and yin deficiency were studied.

The discovery of the potential biomarkers of the constitutions of yang deficiency and yin deficiency and the syndromes of spleen and stomach yang deficiency and stomach yin deficiency provides the objective evidence for the relationship between constitutions and syndromes from the aspect of metabonomics. The differences of energy metabolism, lipid metabolism, glycometabolism, and amino acid metabolism between the constitutions of yang deficiency and yin deficiency and the syndromes of spleen and stomach yang deficiency and stomach yin deficiency were discovered with the changes of neurotransmitters and viscera function. |
