          摘   要  目的  基于Jagged-1/Notch-1信号通路探讨落新妇苷(AST)对慢性肾功能衰竭(CRF)大鼠肾损伤的影响及潜在机制。方法
          以 5/6 肾切除术法构建 CRF 模型,并将造模成功的大鼠随机分为模型组(Model 组)、AST 低剂量组(AST-L 组)、AST 高剂量组
         (AST-H 组)、AST 高剂量+Notch 通路激活剂(Jagged1/FC 嵌合蛋白,简称“JFC”)组(AST-H+JFC 组),另设开腹不切除的对照组
         (CK 组),每组 10 只。AST-L 组和 AST-H 组大鼠分别灌胃 40、80 mg/kg 的 AST,AST-H+JFC 组大鼠同时灌胃 80 mg/kg 的 AST 和
          0.5 mg/kg 的 JFC,CK 组和 Model 组大鼠灌胃等体积生理盐水,每天 1 次,连续 4 周。末次给药后,检测各组大鼠血清尿素氮
         (BUN)、血清肌酐(SCr)、24 h尿液尿蛋白(UP)水平以及血清乳酸脱氢酶(LDH)、肿瘤坏死因子α(TNF-α)、白细胞介素6(IL-6)、
          IL-10水平;观察其肾组织形态和纤维化情况,检测肾组织线粒体中腺苷三磷酸(ATP)含量和钠钾ATP酶、钙镁ATP酶活性,以及
          肾组织中转化生长因子 β(TGF-β)、低氧诱导因子 1α(HIF-1α)、α-平滑肌肌动蛋白(α-SMA)、切割型胱天蛋白酶 3(cleaved-
          caspase-3)、Jagged-1、Notch-1 蛋白的表达水平。结果  与 CK 组比较,Model 组大鼠肾组织损伤明显,肾组织纤维化严重;其血清
          BUN、SCr和尿液UP水平,血清LDH、TNF-α、IL-6水平,以及肾组织中TGF-β、HIF-1α、α-SMA、cleaved-caspase-3、Jagged-1、Notch-
          1 蛋白的表达水平均显著升高,血清 IL-10 水平以及肾组织线粒体中 ATP 含量和钠钾 ATP 酶、钙镁 ATP 酶活性均显著降低(P<
          0.05)。与Model组比较,AST各剂量组大鼠肾组织损伤和纤维化均有所减轻;其血清BUN、SCr和尿液UP水平,血清LDH、TNF-
          α、IL-6水平,以及肾组织中TGF-β、HIF-1α、α-SMA、cleaved-caspase-3、Jagged-1、Notch-1蛋白的表达水平均显著降低,血清IL-10
          水平以及肾组织线粒体中 ATP 含量和钠钾 ATP 酶、钙镁 ATP 酶活性均显著升高,且 AST-H 组上述指标的变化较 AST-L 组明显
         (P<0.05)。JFC可显著逆转高剂量AST对CRF大鼠肾损伤的改善作用(P<0.05)。结论  AST可减轻CRF大鼠炎症、肾组织损伤
          和纤维化,改善肾组织线粒体能量代谢,上述作用可能与抑制Jagged-1/Notch-1信号通路有关。

          ABSTRACT    OBJECTIVE  To  investigate  the  effect  and  potential  mechanism  of  astilbin (AST)  on  renal  injury  in  chronic  renal
          failure (CRF) rats based on the Jagged-1/Notch-1 signaling pathway. METHODS  CRF model was constructed by 5/6 nephrotomy.
          The  successfully  modeled  rats  were  randomly  separated  into  Model  group, AST  low-dose  group (AST-L  group), AST  high-dose
          group (AST-H group), high-dose of AST+Notch pathway activator (Jagged-1/FC chimerin, referred to as “JFC”) group (AST-H+
          JFC group), and control group (CK group) for open surgery without resection was set up, with 10 rats in each group. The rats in
          the  AST-L  group  and  AST-H  group  were  given  40  and  80  mg/kg  AST,  respectively;  the  rats  in  the  AST-H+JFC  group  were
          simultaneously  given  80  mg/kg  AST  and  0.5  mg/kg  JFC,  and  the  rats  in  the  CK  group  and  Model  group  were  given  an  equal
          volume of normal saline, once a day, for 4 weeks. After the last administration, the serum levels of blood urea nitrogen (BUN),
          serum creatinine (SCr), and the level of 24 h urinary protein (UP) in urine, as well as the serum levels of lactate dehydrogenase
         (LDH),  tumor  necrosis  factor-α (TNF-α),  interleukin-6 (IL-6)  and  IL-10  in  each  group  were  detected.  The  morphology  and
          fibrosis of renal tissue were observed. The content of adenosine triphosphate (ATP) and the activities of sodium-potassium ATPase
          and  calcium-magnesium  ATPase  in  mitochondria  of  renal  tissue  were  detected.  The  protein  expressions  of  transforming  growth
                                                              factor- β (TGF- β),  hypoxia-inducible  factor-1α (HIF-1α),
