摘 要 目的 探究紫檀芪(PTE)对糖尿病性皮肤溃疡模型大鼠创面愈合的影响及机制。方法 取10只SD大鼠为对照组,其余大
鼠以饲喂高脂高糖饲料+腹腔注射链脲佐菌素+剪去背部标记区域皮肤及皮下组织建立糖尿病性皮肤溃疡模型后,随机分为模型
组、PTE低剂量组(40 mg/kg)、PTE高剂量组(80 mg/kg)和PTE高剂量+PP2组(80 mg/kg的PTE+2 mg/kg的SRC抑制剂PP2),每组
10只。于建模后第2天,各药物组大鼠腹腔注射相应药液,对照组和模型组大鼠腹腔注射生理盐水,每天1次,连续14 d。测算各
组大鼠给药第 7、14 天的创面愈合率,检测血清中白细胞介素 1β(IL-1β)、IL-6、肿瘤坏死因子 α(TNF-α)、血管内皮生长因子
(VEGF)含量,观察创面肉芽组织的病理变化并检测创面肉芽组织中SRC/促分裂原活化的蛋白激酶激酶(MEK)/胞外信号调节激
酶(ERK)信号通路相关蛋白的表达。结果 与对照组比较,模型组大鼠的创面愈合率、血清中VEGF含量和创面肉芽组织中SRC、
MEK1/2、ERK1/2的磷酸化水平均显著降低(P<0.05),血清中IL-1β、IL-6、TNF-α含量均显著升高(P<0.05),创面肉芽组织中有
明显的炎症细胞浸润,新生血管减少;与模型组比较,PTE低、高剂量组大鼠上述指标均显著改善(P<0.05),创面肉芽组织的病理
损伤均明显改善;PP2显著逆转了高剂量PTE对上述指标的改善作用(P<0.05)。结论 PTE能促进糖尿病性皮肤溃疡模型大鼠的
创面愈合,其作用机制可能与激活SRC/MEK/ERK信号通路有关。

ABSTRACT OBJECTIVE To explore the effects of pterostilbene (PTE) on wound healing in diabetic skin ulcer model rats and
its mechanism. METHODS Ten SD rats were grouped into control group; after diabetic skin ulcer model of other rats was induced
by giving high-fat and high-sugar diet+intraperitoneal injection of streptozotocin+cutting off the skin and subcutaneous tissue in the
marked area of the back, model rats were randomly divided into model group, PTE low-dose group (40 mg/kg), PTE high-dose
group (80 mg/kg), PTE high-dose+PP2 group (80 mg/kg PTE+2 mg/kg SRC inhibitor PP2), with 10 rats in each group. On the
second day after modeling, the rats in each drug group were intraperitoneally injected with corresponding drug solutions, while the
rats in control group and model group were intraperitoneally injected with normal saline, once a day, for 14 consecutive days. The
wound healing rate of rats in each group was measured on the 7th and 14th day of administration; the contents of interleukin-1β
(IL-1β), IL-6, tumor necrosis factor- α (TNF- α) and vascular endothelial growth factor (VEGF) in the serum of rats were
detected; the pathological changes of wound granulation tissue were observed, and the expressions of SRC/mitogen-activated
protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway-related proteins in wound granulation
tissue were detected. RESULTS Compared with control group, the wound healing rate, serum content of VEGF, the
phosphorylation levels of SRC, MEK1/2 and ERK1/2 were
