          摘   要  目的  探究穿心莲内酯(Andro)对糖尿病足大鼠血管生成的影响,并基于Hippo-Yes相关蛋白(YAP)信号通路探索其作用
          机制。方法  采用小剂量链脲佐菌素联合高脂高糖饮食复制2型糖尿病大鼠模型,在其建模成功的基础上,用烫伤法建立糖尿病
          足大鼠模型。将造模成功的大鼠随机分为 5 组,每组 12 只:Model 组,Andro 低、中、高剂量组(1、10、20 mg/kg)和抑制剂组
         (20 mg/kg Andro+100 mg/kg的Hippo-YAP信号通路特异性抑制剂维替泊芬)。另外取12只健康大鼠作为Control组。各组大鼠
          灌胃和腹腔注射溶剂或相应药物,每日 1 次,连续 2 周。给药结束后,检测大鼠创面愈合情况、空腹血糖(FBG)和空腹胰岛素
         (FINS)含量;以HE染色法观察大鼠创面组织损伤及毛细血管数;采用流式细胞仪进行大鼠外周血内皮祖细胞(EPCs)计数;采用
          全自动生化分析仪检测大鼠血清总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)含
          量;采用Western blot法检测各组大鼠创面组织中缺氧诱导因子1α(HIF-1α)、血管内皮生长因子(VEGF)及Hippo-YAP信号通路
          相关蛋白的表达情况。结果  与Control组比较,Model组大鼠创面愈合率,毛细血管数,EPCs比例,HDL-C含量,HIF-1α、VEGF蛋
          白表达水平及哺乳动物Ste20样激酶1、大肿瘤抑制基因1、YAP蛋白的磷酸化水平均显著降低,FBG、FINS水平及TC、TG、LDL-C
          含量均显著升高(P<0.05)。与Model组比较,Andro低、中、高剂量组大鼠上述指标均显著逆转,且呈剂量依赖性(P<0.05);维替
          泊芬减弱了Andro的上述逆转作用(P<0.05)。结论  Andro具有降低糖尿病足大鼠血糖、血脂,促进糖尿病足大鼠血管生成及创
          面愈合的作用,其作用机制可能与激活Hippo-YAP信号通路有关。

          ABSTRACT    OBJECTIVE  To  investigate  the  effects  of  andrographolide (Andro)  on  angiogenesis  in  rats  with  diabetic  foot  and
          to explore its mechanism of action based on the Hippo-Yes-associated protein (YAP) signaling pathway. METHODS The rat model
          of  type  2  diabetes  was  established  by  using  low-dose  streptozotocin  combined  with  high-fat  and  high-glucose  diet.  On  the  basis  of
          successful  modeling,  the  rat  model  of  diabetes  foot  was  established  by  scalding.  Model  rats  were  randomly  divided  into  5  groups
          with 12 rats in each group: model group, Andro low-dose, medium-dose, and high-dose groups (1, 10, and 20 mg/kg), as well
          as  inhibitor  group (20  mg/kg Andro+100  mg/kg  of  verteporfin,  an  specific  inhibitor  of  Hippo-YAP  signaling  pathway);  other  12
          healthy rats were included in the Control group. Rats in each group were intragastrically and intraperitoneally injected with solvents
          or corresponding drugs, once a day, for 2 consecutive weeks. The wound healing, fasting blood glucose (FBG) and fasting insulin
         (FINS) were detected in rats after medication. HE staining was performed to observe the tissue damage and capillary number of rat
          trauma;  the  number  of  endothelial  progenitor  cells (EPCs)  in  peripheral  blood  of  rats  was  counted  by  using  flow  cytometry;  the
          contents  of  serum  total  cholesterol (TC),  triglyceride (TG),  high-density  lipoprotein  cholesterol (HDL-C)  and  low-density
          lipoprotein  cholesterol (LDL-C)  in  rats  were  determined  by  fully  automatic  biochemical  analyzer;  the  expressions  of  hypoxia-
                                                              inducible  factor  1α (HIF-1α),  vascular  endothelial  growth
