摘 要: | 目的:建立金黄色葡萄球菌联合大肠埃希菌混合感染的糖尿病溃疡大鼠模型,为糖尿病溃疡实验研究提供合适的动物模型。方法:将40只SD雄性大鼠随机分为5组,普通溃疡组、糖尿病溃疡组、糖尿病溃疡治疗组、模型组、模型治疗组。造模后取局部皮肤组织行HE染色;采用酶联免疫吸附(ELISA)检测大鼠血清中高敏C反应蛋白(H-CRP)、成纤维细胞生长因子(bFGF)、肿瘤坏死因子-α(TNF-α)、糖基化终末产物(AGEs)、白细胞介素-1β(IL-1β)、白细胞介素-6(IL-6)、一氧化氮(NO)含量水平,并记录创面愈合时间,对该模型的稳定性、实用性进行评估。结果:模型组溃疡愈合时间较其他组明显延迟(P<0.001);模型组及模型治疗组血清中H-CRP水平高于普通溃疡组、糖尿病溃疡组、糖尿病溃疡治疗组(P<0.05);溃疡愈合后糖尿病溃疡组血清中H-CRP、bFGF、AGEs、TNF-α、IL-1β、IL-6、NO水平均高于普通溃疡组(P<0.05);模型组血清中H-CRP、AGEs、TNF-α、IL-1β、IL-6、NO水平均高于其他组(P<0.05);模型治疗组血清中的H-CRP、AGEs、TNF-α、IL-1β、IL-6、NO水平均高于糖尿病溃疡治疗组(P<0.05)。结论:该模型符合混合感染性糖尿病溃疡局部环境,为相关研究提供了新的选择。
