         (VEGFR2)信号通路对肛瘘术后大鼠创面愈合的影响及潜在机制。方法  以SD大鼠为对象,采用大肠埃希菌液感染创面的方法
          复制肛瘘术后大鼠模型,并将其随机分为模型组,PNS低、高剂量组(15、30 mg/cm),PNS高剂量+2-甲氧基雌二醇(2ME2)组(PNS

          30 mg/cm +HIF-1α抑制剂2ME2 4 mg/kg),每组10只;另选10只正常大鼠,仅进行背部脱毛处理,作为对照组。各药物组大鼠肌

         (MVD)和胶原蛋白Ⅰ(collagen Ⅰ)、纤维连接蛋白(FN)阳性表达情况,血清中血管生成相关因子[VEGF、血管生成素Ⅰ(Ang-
          Ⅰ)、Ang-Ⅱ]水平和血清、创面组织中炎症因子[白细胞介素6(IL-6)、IL-2]水平,以及创面组织中HIF-1α/VEGF/VEGFR2信号通路
          相关蛋白的表达情况。结果  模型组大鼠创面组织MVD及collagen Ⅰ、FN表达水平,血清及创面组织中IL-6、IL-2水平均较对照
          组显著升高(P<0.05),血清中VEGF、Ang-Ⅰ、Ang-Ⅱ水平均较对照组显著降低(P<0.05)。PNS低、高剂量组大鼠创面愈合率,创

          平均较模型组显著升高(P<0.05),血清及创面组织中IL-6、IL-2水平均较模型组显著降低(P<0.05),且高剂量PNS的作用更强
         (P<0.05);2ME2可减弱PNS对肛瘘术后大鼠上述指标的改善作用(P<0.05)。结论  PNS可促进血管生成相关因子产生并抑制
          促炎因子生成,从而促进肛瘘术后大鼠创面的愈合,上述作用与激活HIF-1α/VEGF/VEGFR2信号通路有关。

          ABSTRACT   OBJECTIVE  To  investigate  the  effect  and  mechanism  of  Panax  notoginseng  saponins (PNS)  on  wound  healing
          after anal fistula surgery in rats by regulating the hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF)/
          vascular  endothelial  growth  factor  receptor-2 (VEGFR2)  signaling  pathway.  METHODS  SD  rats  were  selected  to  establish  a
          postoperative rat model of anal fistula by infecting wound with Escherichia coli. The model rats were randomly grouped into model
          group,  PNS  low-dose  and  high-dose  groups (15,  30  mg/cm),  high-dose  of  PNS+2-methoxyestradiol (2ME2)  group (PNS  30
