          摘   要  目的  探讨肾必宁颗粒通过调控 CXC 型趋化因子配体 12(CXCL12)/CXC 型趋化因子受体 4(CXCR4)/信号转导与转录
          激活因子3(STAT3)信号通路对免疫球蛋白A肾病(IgAN)大鼠的肾脏保护作用及机制。方法  将60只大鼠随机分为空白组(n=
          12)与造模组(n=48)。造模组大鼠采用牛血清白蛋白、四氯化碳联合脂多糖诱导IgAN模型并进行模型验证。最终共55只大鼠
         (空白组9只、造模组46只)纳入后续研究。将造模组大鼠随机分为模型组(n=10)、醋酸泼尼松组[阳性对照组,6.25 mg/(kg·d),
          n=12]和肾必宁颗粒低、高剂量组[4.17、8.33 g/(kg·d),n=12],每日灌胃给药/蒸馏水1次,连续4周。末次给药后,检测大鼠尿液
          及血清中生化指标,观察大鼠肾组织病理形态学改变,检测大鼠肾组织中 IgA 沉积以及 CXCL12、CXCR4、STAT3 mRNA 和
          CXCL12、CXCR4、STAT3、磷酸化STAT3(p-STAT3)蛋白表达情况,并检测肾组织中白细胞介素6(IL-6)水平。结果  与模型组比
          较,肾必宁颗粒低、高剂量组大鼠尿红细胞计数、24 h尿蛋白总量以及血尿素氮、血肌酐、丙氨酸氨基转移酶水平均显著降低(P<
          0.05),白蛋白水平均显著升高(P<0.05);肾组织病理损伤减轻,系膜区 IgA 沉积减少(P<0.05);肾组织中 CXCL12、CXCR4、
          STAT3 mRNA及其蛋白表达水平,STAT3蛋白的磷酸化水平以及IL-6水平均显著降低(P<0.05)。结论  肾必宁颗粒可能通过抑
          制CXCL12/CXCR4/STAT3信号通路活化,下调炎症因子IL-6表达,减轻肾脏炎症反应,进而改善肾组织病理损伤,发挥对IgAN大
          鼠的肾脏保护作用。

          ABSTRACT    OBJECTIVE  To  investigate  the  renal  protective  effect  and  mechanism  of  Shenbining  granule  on  IgA  nephropathy
         (IgAN) rats by regulating the CXC chemokine motif ligand 12 (CXCL12)/CXC chemokine receptor 4 (CXCR4)/signal transducer
          and  activator  of  transcription  3 (STAT3)  signaling  pathway.  METHODS  A  total  of  60  rats  were  randomly  assigned  into  blank
          group (n=12) and modeling group (n=48). IgAN model of modeling group was induced by using bovine serum albumin, carbon
          tetrachloride and lipopolysaccharide, followed by model validation. Ultimately, a total of 55 rats (9 in the blank group, 46 in the
          modeling  group)  were  included  in  the  subsequent  study.  The  rats  in  the  modeling  group  were  randomly  divided  into  model  group
         (n=10),  prednisone  acetate  group  [positive  control  group,  6.25  mg/(kg·d),  n=12],  Shenbining  granule  low-  and  high-dose
          groups  [4.17,  8.33  g/(kg·d),  n=12].  They  were  given  relevant  medicine/distilled  water  intragastrically,  once  a  day,  for  4
          consecutive weeks. After the last medication, biochemical indicators in the urine and serum of rats were measured, and pathological
          morphological  changes  in  the  renal  tissues  of  rats  were  observed.  IgA  deposition  in  the  renal  tissues,  as  well  as  the  mRNA
