        摘   要   目的 探讨金雀花根水提物(WCS)和乙醇提取物(ECS)对小鼠高尿酸血症(HUA)的影响。方法 将昆明种小鼠随机分为
        正常对照组、模型组、别嘌醇组(阳性对照,5 mg/kg)、苯溴马隆组(阳性对照,7.8 mg/kg)和WCS低、中、高剂量组(38、75、150 mg/kg)以
        及ECS低、中、高剂量组(50、100、200 mg/kg),每组10只。除正常对照组外,其余小鼠连续7 d腹腔注射氧嗪酸钾联合灌胃次黄嘌
        呤建立HUA 模型。于建模第3天,各给药组小鼠灌胃相应药物,正常对照组和模型组灌胃等体积生理盐水,每日1次,连续5 d。
        称定给药期间小鼠的体质量;末次给药1 h后,计算肝、肾、脾的脏器指数,测定血清尿酸(SUA)、血尿素氮(BUN)、血肌酐(SCR)含
        量以及血清和肝组织中黄嘌呤氧化酶(XOD)活性;检测肝组织中XOD mRNA和蛋白的相对表达量以及肾组织中葡萄糖转运蛋
        白9(GLUT9)、尿酸转运蛋白1(URAT1)、有机阴离子转运蛋白1(OAT1)的相对表达量;观察肾组织的病理变化。结果 各组小鼠
        肝脏指数和脾脏指数差异无统计学意义(P>0.05)。与正常对照组比较,除别嘌醇组外的各给药组小鼠的体质量和BUN、SCR含
        量差异无统计学意义(P>0.05);模型组和别嘌醇组小鼠的肾脏指数、SUA含量均显著升高(P<0.05);模型组小鼠血清和肝组织
        中XOD活性、肝组织中XOD mRNA和蛋白的相对表达量、肾组织中GLUT9和URAT1蛋白的相对表达量均显著升高(P<0.05),
        肾组织中OAT1蛋白的相对表达量显著降低(P<0.05)。与模型组比较,WCS和ECS各剂量组小鼠的肾脏指数均显著降低(P<
        0.05),肾组织病理损伤明显改善;各给药组小鼠的SUA含量、血清和肝组织中XOD活性、肝组织中XOD mRNA和蛋白的相对表
        达量、肾组织中URAT1蛋白的相对表达量均显著降低(P<0.05);苯溴马隆组和ECS高剂量组小鼠肾组织中GLUT9蛋白的相对
        表达量均显著降低(P<0.05);苯溴马隆组和WCS低、高剂量组以及ECS低剂量组小鼠肾组织中OAT1蛋白的相对表达量均显著
        升高(P<0.05)。结论 WCS和ECS能够显著降低HUA模型小鼠SUA含量,改善其肾脏的病理状态,其作用机制可能与抑制XOD
        活性和尿酸重吸收、下调XOD蛋白和mRNA表达有关。

        ABSTRACT    OBJECTIVE To investigate the effects of water extract (WCS) and ethanol extract (ECS) from the root of
        Caragana sinica on hyperuricemia(HUA)in mice. METHODS Kunming mice were randomly divided into normal control group,
        model group,allopurinol group(positive control,5 mg/kg),benzbromarone group(positive control,7.8 mg/kg),WCS low-dose,
        medium-dose and high-dose groups(38,75,150 mg/kg),ECS low-dose,medium-dose and high-dose groups(50,100,200 mg/kg),
        with 10 mice in each group. Except for the normal control group,the other mice were given potassium oxazinate intraperitoneally
        and hypoxanthine intragastrically for consecutive 7 d to establish HUA model. On the third day of modeling,mice in each
        administration group were given corresponding drugs intragastrically,and normal control group and model group were given equal
        volume of normal saline once a day for 5 consecutive days.The body weight of mice were weighted during administration;one hour
        after the last administration,the organ indexes of liver,kidney and spleen were calculated;the contents of serum uric acid(SUA),
        blood urea nitrogen(BUN)and serum creatinine(SCR);the activity of xanthine oxidase(XOD)in serum and liver tissue were
        determined. Relative mRNA and protein expressions of XOD in liver tissue,relative expressions of GLUT9,URAT1 and OAT1 in
                                                            renal tissue were all detected;and the pathological changes of
