Objective:To investigate the plasma samples obtained from tumor patients using ~1H nuclear magnetic resonance(NMR) spectroscopy,and find the biochemical foundation of abnormal Savda described in traditional Uyghur medicine.Methods:A total of 170 tumor patients with abnormal Savda syndrome who were confirmed clinically were enrolled in this study,and 50 healthy volunteers were set up as controls.The plasma ~1H NMR spectra were analyzed using the orthogonal projection to latent structure with discriminant analysis(OPLS-DA) method with unit variance scaling.The discriminative significance of the metabolites was determined using the Pearson’s product-moment correlation coefficient.Results:Compared with the healthy controls,the tumor patients with abnormal Savda syndrome had uniformly correlative low levels of leucine, isoleucine,valine,histidine,tyrosine,alanine,glutamine,creatine,inositol,α-glucose,and B -glucose(P<0.05), but had significantly high levels of formate,malonic acid,acetone,acetate,acetoacetate,pyruvate,B -hydroxy butyrate,carnitine and lipidtemns such as very low density lipoprotein,low density lipoprotein and unsaturated lipids(P<0.05).Conclusion:Tumor patients with abnormal Savda syndrome had similar metabolic changes and characteristics,which indicated a similar pathogenetic process and provides some biochemical basis for traditional Uyghur medicine theory.
