摘要:

背景:糖尿病会影响正常创面愈合过程而形成难愈性创面。
目的:观察局部应用小剂量胰岛素对糖尿病难愈性创面愈合的作用。
方法:将大鼠随机分为实验组与对照组,对照组喂予普通饲料,实验组采用高糖高脂饲料结合小剂量链脲佐菌素诱导大鼠糖尿病模型。随后在各组大鼠背部建立创面,对照组大鼠不予处理,实验组随机等分为模型组、凡士林组和胰岛素组,后2组分别以凡士林和小剂量胰岛素涂抹创面。
结果与结论:实验组大鼠糖尿病诱导成功率几乎100%;模型组、凡士林组和胰岛素组大鼠创面完全上皮化时间均较对照组明显延长(P < 0.05);且与模型组和凡士林组相比,胰岛素组大鼠创面愈合率显著升高,上皮化程度高,并且胶原纤维密度增加,排列较为规整,血管化程度增加。说明局部应用小剂量胰岛素可以促进上皮化、纤维化及血管新生,从而加速糖尿病创面的愈合速度。

Abstract:

BACKGROUND: Diabetes can influence the normal course of wound healing, thus leading to refractory wound.
OBJECTIVE: To observe the effects of topical application of low-dose insulin on diabetes refractory wound healing.
METHODS: Rats were randomly divided into experimental group and control group: rats in the control group were fed with regular diet and those in the experimental group were fed with high-carbohydrates-fat diet. Rats in the experimental group received intraperitoneal injection of streptozotocin to induce diabetic models. Wounds were made on the back of the rats. The rats in the control group received no treatment, while rats in the experimental group were divided into model group, Vaseline group and insulin group. Wounds in the Vaseline group and insulin group were treated with Vaseline and a small dose of insulin, respectively.
RESULTS AND CONCLUTION: The success rate of induction for diabetes in the experimental group was almost 100%. Complete epithelialization time of the wounds in the model group, Vaseline group and insulin group was longer that than that in the control group (P < 0.05). Compared with the model group and the Vaseline group, the wound healing rate of rats in the insulin group was increased significantly with higher epithelialization degree, the density of collagen fibers was increased and arranged in regular, and the degree of vascularization was increased. The results indicate that topical application of low dose insulin can promote the epithelialization, collagen deposition and angiogenesis, thus accelerating diabetic wound healing.
