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.
