To investigate the metabolic characteristics of alzheimer's disease (AD) rat model with abnormal savda syndrome, an abnormal savda rat model with multiple factors is established according to the theory of Uighur traditional medicine, and Aβ1-40 ventricle injection is carried out to establish the alzheimer's disease rat model with abnormal savda syndrome. Then, serum samples from all group rats are analyzed by nuclear magnetic resonance (1H-NMR) spectroscopy (600 MHz), and their spectral profiles are projected by orthogonal projections to latent structures (OPLS-DA) for multivariate statistics. The OPLS-DA analysis shows that compared to the normal group, the pure AD group serum has higher levels of lactic acid, glycoproteins, acetone, VLDL, formic acid and unsaturated lipids, yet a lower level of malonic acid. The abnormal savda syndrome group serum has higher levels of glycoproteins and β-glucose, but lower levels of valine, tyrosine, phenylalanin, and 1-methyl-histidine. The anormal savda syndrome AD group serum has a higher level of unsaturated lipids, but lower levels of glycine, phenylalanine, 1-methyl-histidine, methionine, malonic acid, α-glucose and β-glucose (P<0.05). Compared to the pure AD group, the abnormal savda syndrome group serum has lower levels of leucine, valine, alanine, tyrosine, α-glucose, β-glucose, carnitine, citric acid and unsaturated lipids. The abnormal savda syndrome AD group serum has lower levels of alanine and acetone, but higher levels of β-glucose and creatine (P<0.05). Compared with the abnormal savda syndrome group, the abnormal Savda syndrome AD group serum has higher levels of α-glucose, β-glucose, carnitine and citric acid (P<0.05). It is concluded that the abnormal savda syndrome has certain relevance to the development of alzheimer's disease; compared with the abnormal savda syndrome group and pure AD group, the alerted metabolits and metabolic pathway related with disordered glucose metabolism and energy dysmetabolism have variations during the pathological changing process of disease, and the variation of metabolism in the body of abnormal savda syndrome AD rat is more complex.
