          摘  要  目的  基于肿瘤蛋白p53/微RNA-214(miR-214)/UNC-51样激酶1(ULK1)轴探讨雷公藤多苷(TWM)对糖尿病肾病(DN)
          大鼠肾损伤的影响。方法  将雄性SD大鼠分为正常组(6只)和造模组(28只),造模组大鼠以高脂高糖饲料喂养+链脲佐菌素腹腔
          注射法建立DN模型。将造模成功的大鼠分为模型组、缬沙坦组[8.33 mg/(kg·d)]、TWM组[6.25 mg/(kg·d)],每组8只。各组大鼠
          灌胃相应药液或生理盐水,每天 1 次,连续 6 周。末次给药后,检测各组大鼠尿液/血液中肝肾功能指标[24 h 尿蛋白定量(24 h-
          UTP)、血尿素氮(BUN)、血肌酐(SCr)、白蛋白(ALB)、丙氨酸转氨酶(ALT)]、血脂指标(甘油三酯、总胆固醇)、血糖指标(空腹血
          糖)水平,观察其肾组织病理改变,并检测其肾组织中p53、ULK1、Beclin-1、微管相关蛋白1轻链3(LC3)蛋白及mRNA和miR-214
          的表达情况。结果  与正常组比较,模型组大鼠肾小管上皮水肿明显,细胞肿胀,伴有淋巴细胞浸润;模型组和各药物组大鼠24 h-
          UTP、BUN、SCr、ALT 和糖脂指标水平,p53 蛋白及 mRNA 和 miR-214 的表达均显著升高或上调,而 ALB 水平、LC3-Ⅱ/LC3-Ⅰ、
          LC3 mRNA、ULK1、Beclin-1蛋白及mRNA的表达均显著降低或下调(P<0.01)。与模型组比较,各药物组大鼠肾组织病理学损伤
          均有所好转;其24 h-UTP、BUN、SCr、ALT和糖脂指标水平,p53蛋白及mRNA和miR-214的表达均显著降低或下调,而ALB水平、
          LC3-Ⅱ/LC3-Ⅰ、LC3 mRNA、ULK1、Beclin-1蛋白及mRNA的表达均显著升高或上调(P<0.01)。结论  TWM能减轻DN大鼠的
          肾损伤,改善其肝肾功能和糖脂水平,上述作用可能与调控p53/miR-214/ULK1轴、恢复细胞自噬有关。

          ABSTRACT   OBJECTIVE To investigate the effects of Tripterygium wilfordii multiglycoside (TWM) on renal injury in diabetic
          nephropathy (DN)  rats  through  tumor  protein  p53/microRNA-214 (miR-214)/UNC-51-like  kinase  1 (ULK1)  axis.  METHODS
          Male  SD  rats  were  randomly  divided  into  normal  group (n=6)  and  modeling  group (n=28);  the  modeling  group  was  fed  with
          high  fat  and  high  glucose  plus  intraperitoneal  injection  of  streptozotocin  to  establish  DN  model.  The  modeled  rats  were  randomly
          divided into model group, valsartan group [8.33 mg/(kg·d)] and TWM group[6.25 mg/(kg·d)], with 8 rats in each group. Rats in
          each group were gavaged with the corresponding medication or normal saline, once a day, for 6 consecutive weeks. After the last
          medication, liver and renal function indexes [24 h urinary total protein (24 h-UTP), blood urea nitrogen (BUN), serum creatinine
         (SCr),  albumin (ALB),  alanine  transaminase (ALT)],  blood  lipid  indexes (triglycerides,  total  cholesterol)  and  blood  glucose
          index (fasting  blood  glucose)  in  urine/blood  sample  of  rats  were  detected  in  each  group.  Renal  pathologic  change  was  observed,
          protein and mRNA expressions of p53, ULK1, Beclin-1 and microtubule-associated protein 1 light chain 3 (LC3), and expression
          of miR-214 in renal tissue were also determined. RESULTS Compared with the normal group, the renal tubular epithelium of rats
                                                             in  the  model  group  showed  obvious  edema,  cell  swelling,
