          摘  要  目的  研究关黄柏多糖(PAP)对大鼠痛风性肾病(GN)的改善作用,并通过丝裂原激活蛋白激酶p38(p38 MAPK)/核因子
          κB(NF-κB)/肿瘤坏死因子α(TNF-α)信号通路初步探讨其作用机制。方法  将60只大鼠按体重分层后随机分为正常组(水)、模
          型组(水)、别嘌醇组(阳性对照,20 mg/kg)和PAP高、中、低剂量组(100、50、25 mg/kg,以生药量计),每组10只。除正常组外,其余
          各组大鼠均采取1 500 mg/kg氧嗪酸钾和100 mg/kg腺嘌呤联合灌胃14 d构建GN模型。造模成功后,各组大鼠灌胃相应药物/水,
          每天1次,连续28 d。末次给药后,检测大鼠肾功能相关生化指标[尿酸、肌酐(Cr)、血尿素氮(BUN)、黄嘌呤氧化酶(XOD)],观察
          大鼠肾组织病理形态学变化,检测大鼠肾组织中单核细胞趋化蛋白1(MCP-1)、TNF-α、白细胞介素6(IL-6)蛋白表达水平和p38
          MAPK、NF-κB p65蛋白的磷酸化水平。结果  与正常组比较,模型组大鼠肾小管扩张,肾小球结构损坏,并伴有炎症浸润与纤维
          化;尿酸、Cr、BUN、XOD 含量以及 MCP-1、TNF-α、IL-6 蛋白表达水平和 p38 MAPK、NF-κB p65 蛋白的磷酸化水平均显著升高
         (P<0.05或P<0.01)。与模型组比较,PAP各剂量组大鼠的肾组织病理症状均有不同程度改善;PAP高、中剂量组大鼠尿酸、Cr、
          BUN、XOD含量以及MCP-1、TNF-α、IL-6蛋白表达水平和p38 MAPK、NF-κB p65蛋白的磷酸化水平均显著降低(P<0.05或P<
          0.01)。结论  PAP具有抗GN的作用,其机制可能与抑制p38 MAPK/NF-κB/TNF-α信号通路的激活有关。

          ABSTRACT   OBJECTIVE  To  study  the  effects  of  Phellodendron  amurense  polysaccharides (PAP)  on  improving  gouty
          nephropathy (GN) in rats, and to investigate its mechanism primarily by interfering the p38 mitogen-activated protein kinase (p38
          MAPK)/nuclear  factor-κB(NF-κB)/tumor  necrosis  factor-α(TNF-α).  METHODS  Sixty  rats  were  randomly  divided  into  normal
          group (water), model group (water), allopurinol group (positive control, 20 mg/kg), PAP high-dose, medium-dose and low-dose
          groups (100,  50,  25  mg/kg,  by  raw  material)  after  being  stratified  by  body  weight,  with  10  rats  in  each  group.  Except  for  the
          normal  group,  the  other  groups  were  induced  to  construct  GN  model  by  giving  1  500  mg/kg  potassium  oxazinate  and  100  mg/kg
          adenine  intragastrically  for  14  days.  After  modeling,  the  rats  in  each  group  were  given  relevant  medicine/water  intragastrically,
          once a day, for consecutive 28 days. After the last medication, the levels of biochemical parameters related to renal function [uric
          acid,  creatinine (Cr),  blood  urea  nitrogen (BUN),  xanthine  oxidase (XOD)]  were  detected  in  rats,  and  the  histopathological
                                                             changes  in  the  rat  kidney  were  observed.  The  protein
