摘要: 目的: 探讨中药制剂土茯苓、泽泻以及车前子是否调节高尿酸大鼠肾脏尿酸转运蛋白-1(uric acid transporters1,URAT1)mRNA表达。方法: 将48只雄性Wistar大鼠随机分为正常对照组、模型组、苯溴马隆组、土茯苓组、泽泻组以及车前子组,每组8只。用氧嗪酸钾盐建立高尿酸血症大鼠模型。采用实时荧光定量PCR检测土茯苓、泽泻以及车前子对高尿酸大鼠肾脏URAT1基因的mRNA相对表达量。结果: 苯溴马隆组、泽泻组、车前子组以及土茯苓组血尿酸值明显低于模型组(均P<0.01)。土茯苓、车前子与苯溴马隆组的URAT1 mRNA表达均低于模型组。结论: 土茯苓、车前子促进尿酸排泄机制可能与通过下调大鼠肾脏URAT1基因的mRNA表达有关。

Abstract: AIM: To explore whether Chinese Traditional Medicine such as alismatales, plantaginaceae and smilax glabra can regulate the hyperuricemia mice uric anionic exchanger 1(URAT1) mRNA expression of rats. METHODS: The 48 Wistar rats were randomly divided into control group, model group, benzbromarone group, alismatales group, plantaginaceae group and smilax glabra group. There were 8 rats every group. Alismatales, plantaginaceae,smilax glabra and benzbromarone were given to rats with hyperuricemia model established with potassium oxonate. The quantitative Real-time PCR method was used for detection of URAT1 mRNA gene expression. RESULTS: The blood uric acid level of benzbromarone group, alismatales group, plantaginaceae group and smilax glabra group were significantly lower than those in the model group (P<0.01). The expression of URAT1 mRNA in benzbromarone group, plantaginaceae group, benzbromarone group were lower than those in model group. CONCLUSION: The mechanism for plantaginaceae and smilax glabra may be relevant in inhibiting URAT1 gene mRNA expression of rats, thus accelerating the excretion of uric acid.
