Hyperuricemia

Brief summary

This study aims to explore the changes in metabolic-related indicators in patients with hyperuricemia under the intervention of barley green, reveal the clinical effect of barley green in regulating uric acid metabolism, and preliminarily clarify the mechanism of barley green influencing uric acid metabolism through in vitro experiments related to xanthine oxidase. This study plans to recruit patients with hyperuricemia who visit the clinical nutrition department and rheumatology and immunology department of Peking University People's Hospital, randomly dividing them into an intervention group and a control group. The intervention group will take barley green plus a balanced diet plan, while the control group will only be given a balanced diet plan. General clinical data will be collected, and nutritional measurements will be conducted. Venous blood will be drawn for the determination of uric acid metabolism-related indicators, xanthine oxidase activity, and inflammatory factor levels. The differences in uric acid and related metabolic indicators, as well as xanthine oxidase activity, between the two groups will be observed and compared to provide a scientific basis for the clinical application of barley green in non-pharmacological intervention and medical nutrition therapy for hyperuricemia.
