ABSTRACT
Objective To study the plasma metabolomics features of SD rats with wei-qi deficiency respectively in spring, summer, autumn and winter; To seek the potential markers related to wei-qi deficiency; To discuss the essence of wei-qi deficiency.MethodsTwenty male SD rats were adaptively fed 7 days before Chinese Vernal Equinox Day, Summer Solstice, Autumn Equinox and Winter Solstice, synchronous controled with temporal condition. The rats were randomly divided into experimental and control groups according to random number method. Rats in the experimental groupwere made into wei-qi deficiency models through fatigue stimulation alternately with cold and heat stimulation. Blood was collected at 12:00 each solar term. High performance liquid chromatography- mass spectrometry instrument was used to detect plasma metabolites. Partial least squates-discriminant analysis was used to process statistical analysis of the data to compared the original data of plasma metabolomics between the two groups of each season, and explore the difference metabolic markers between each two groups, then speculate the potential biomakers of wei-qi differency.ResultsWith the changes of spring, summer, autumn and winter, significant differences were showed in metabolic profile between the experimental and control groups. Homocysteine showed a significant difference in spring, summer and autumn; Ceramide showed a significant difference in summer and winter; Testosterone showed a significant difference in spring and summer; Cyclic guanosine monophosphate showed a significant difference in autumn and winter; Sarcosine showed a significant difference in spring, summer and winter. The physiological functions of these substances related to lipid metabolism, amino acid metabolism, neurotransmitter and hormone regulation.ConclusionPotential biomakers of wei-qi deficiency changed along with the seasonal variation, which mainly reflected in lipid metabolism, amino acid metabolism, neurotransmitter and hormone regulation.
