Objective:
To explore the association between uric acid and the prevalence of hyperlipidemia via the NHANES database, a combined hyperuricemia-hyperlipidemia (HUA-HLP) quail model was subsequently established to investigate the pathological characteristics of the model.
Methods:
In the NHANES database, information on patients with hyperuricemia is collected, and the association between serum uric acid levels and the prevalence of hyperlipidemia is analyzed by adjusting for confounding variables. A high-purine and high-fat diet was prepared with a ratio of regular feed-yeast extract powder-lard = 15:2:3. By measuring uric acid and blood lipid levels, and observing the activities of uric acid-producing enzymes and enzymes related to lipid metabolism synthesis and decomposition, the metabolic disorder and pathological characteristics of the model were evaluated.
Results:
By adjusting for confounding variables, it is found that as serum uric acid levels increase, the prevalence of hyperlipidemia rises significantly. The high-purine and high-fat diet successfully induced a quail model of hyperuricemia combined with hyperlipidemia. During the first week, serum uric acid, triglyceride, total cholesterol, and low-density lipoprotein cholesterol levels were significantly elevated and remained high until the end of the experiment. Serum free fatty acid levels were significantly increased from the second week and remained at a high level. Serum high-density lipoprotein cholesterol levels were significantly reduced from the third week and remained stable thereafter. In addition, the enzymes involved in uric acid synthesis as well as those related to lipid metabolism (including synthesis and decomposition) also exhibited significant abnormalities.
Conclusions:
In the human body, uric acid and lipid metabolism interact with each other and exacerbate one another's abnormalities. A high-purine and high-fat diet can induce a quail model of hyperuricemia combined with hyperlipidemia. Uric acid and lipid metabolism are simultaneously disturbed, and the activities of uric acid-producing enzymes as well as enzymes related to lipid metabolism synthesis and decomposition are also altered.
