摘 要 目的 探究三七总皂苷(PNS)调节缺氧诱导因子 1α(HIF-1α)/血管内皮生长因子(VEGF)/血管内皮生长因子受体 2
(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

内或(和)腹腔注射相应药液,每天1次,持续3周。末次给药后,检测各组大鼠的创面愈合率(对照组除外),创面组织微血管密度
(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
面组织MVD,血清中VEGF、Ang-Ⅰ、Ang-Ⅱ水平,创面组织中collagen Ⅰ、FN表达水平和HIF-1α、VEGF、VEGFR2蛋白的表达水
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
2
mg/cm +HIF-1α inhibitor 2ME2 4 mg/kg), with 10 rats in each group. Another 10 normal rats were selected for back hair removal

treatment as the control group. Each drug group was injected with the corresponding drug solution intramuscularly or (and)
intraperitoneally, once a day, for 3 weeks. After the last administration, the wound healing rate (excluding the control group),
microvascular density (MVD), the expression of collagen Ⅰ
