NCT04909489

Brief Summary

Clinical epidemiological investigation and modern statistics will be used. Syndrome was quantified by TCM syndrome score scale. Metabonomics, proteomics, transcriptomics, enzyme-linked immunosorbent assay, xanthine oxidation method and thiobarbital method will be used to detect the relevant indicators in serum, urine and tongue coating, and "disease syndrome cell model" will be constructed to detect the relevant indicators. Objective to clarify the epigenetic basis, molecular biological regulation mechanism and core function characteristics of phgdh expression decline caused by PDR and SKYD of dyslipidemia, analyze the correlation between phgdh, serine metabolic pathway product concentration and oxidative stress level, and reveal the scientific connotation of the disease syndrome.
