          摘   要  目的  探究蛇床子素(OST)通过超音刺猬(SHH)信号通路对大鼠皮肤创面愈合和血管生成的影响。方法  构建全层皮肤
          缺损伤口模型大鼠,然后随机分为模型组(Model组),低、中、高剂量OST组(OST-L、OST-M、OST-H组,20、30、40 mg/kg OST),高
          剂量OST+SHH抑制剂环巴胺组(OST-H+环巴胺组,40 mg/kg OST+10 mg/kg环巴胺),每组12只;另选取12只不造模大鼠作为对
          照组。在给药第1、7、14天时观察大鼠创面愈合情况,并计算创面愈合率;观察大鼠创面组织的病理学变化和胶原蛋白沉积情况;
          检测大鼠创面组织中血管生成素 1(Ang-1)、碱性成纤维细胞生长因子(bFGF)水平;检测大鼠创面组织中血管内皮生长因子 A
         (VEGFA)、血管内皮生长因子受体2(VEGFR-2)mRNA相对表达量;检测大鼠创面组织中VEGFA、VEGFR-2、SHH、神经胶质瘤相
          关癌基因同源蛋白1(GLI1)蛋白的表达水平。结果  与Model组大鼠相比,OST-M、OST-H组大鼠皮肤创面愈合率(给药第7天和
          第14天),胶原蛋白相对表达量,创面组织中Ang-1、bFGF水平,VEGFA、VEGFR-2 mRNA和蛋白表达水平以及SHH、GLI1蛋白表
          达水平均显著升高(P<0.05);创面组织再上皮化明显,炎症细胞浸润和肉芽组织水肿减轻,新生血管数增多。SHH抑制剂环巴胺
          减弱了OST对大鼠皮肤创面愈合和血管生成的促进作用。结论  OST可能通过激活SHH信号通路促进大鼠皮肤创面愈合和血管
          生成。

          ABSTRACT    OBJECTIVE  To  investigate  the  effects  of  osthole (OST)  on  skin  wound  healing  and  angiogenesis  in  rats  by
          regulating the sonic hedgehog (SHH) signaling pathway. METHODS Full-layer skin defect wound model rats were established and
          then  randomly  separated  into  Model  group,  OST  low-dose,  medium-dose  and  high-dose  groups (OST-L  group,  OST-M  group,
          OST-H group, 20, 30, 40 mg/kg OST), high-dose OST+SHH inhibitor cyclopamide group (OST-H+cyclopamide group, 40 mg/kg
          OST+10  mg/kg  cyclopamide),  with  12  rats  in  each  group. Another  12  rats  were  selected  as  the  control  group. The  wound  healing
          of rats on 1, 7 and 14 days of administration was observed, and the wound healing rate of rats in each group was measured. The
          pathological  changes  and  collagen  deposition  in  rat  wound  tissue  were  observed;  the  levels  of  angiopoietin-1 (Ang-1)  and  basic
          fibroblast growth factor (bFGF) in wound tissue of rats were detected; the relative expressions of vascular endothelial growth factor
          A (VEGFA) and vascular endothelial growth factor receptor-2 (VEGFR-2) mRNA were also detected in wound tissue of rats; the
          protein  expressions  of  VEGFA,  VEGFR-2,  SHH  and  glioma-associated  oncogene  homolog-1 (GLI1)  were  determined  in  wound
          tissue of rats. RESULTS Compared with Model group, the healing rate of skin wound, relative expression of collagen protein, the
          levels of Ang-1 and bFGF, the mRNA and protein expressions of VEGFA and VEGFR-2, and the protein expressions of SHH and
          GLI1  were  all  significantly  increased  in  OST-M  and  OST-H  groups (P<0.05).  The  wound  tissue  underwent  significant  re-
          epithelialization,  with  reduced  inflammatory  cell  infiltration  and  granulation  tissue  edema,  and  an  increase  in  the  number  of  new
          blood vessels. SHH inhibitor cycloparamide weakened the promoting effects of OST on skin wound healing and angiogenesis in rats.
          CONCLUSIONS OST may promote skin wound healing and angiogenesis in rats by activating the SHH signaling pathway.
