尿酸是人体嘌呤代谢的终产物,主要经肝尿酸盐氧化酶(尿酸酶)分解形成尿囊素由尿中排出,其产生过多或排除减少均可导致血尿酸水平升高。随着人们生活水平的提高及饮食结构的改变,人群尿酸水平逐渐升高,高尿酸血症的患病率也因此逐年上升。近年来,越来越多的研究表明,高尿酸血症可能是很多血管疾病的危险因素之一,因此了解高尿酸血症的诊断标准、流行特征、 Uric acid is the end product of purine metabolism, mainly by the decomposition of hepatic urate oxidase (uricase) to form allantoin excreted by the urine, its excessive production or reduce the elimination can lead to elevated serum uric acid levels. With the improvement of people’s living standards and changes in diet, people’s uric acid levels gradually increased, the prevalence of hyperuricemia and therefore increased year by year. In recent years, more and more studies have shown that hyperuricemia may be one of the risk factors of many vascular diseases, so to understand the diagnostic criteria of hyperuricemia, epidemiological characteristics,
