糖尿病伤口愈合困难的血管病变机制及治疗药物研究进展

Angiopathic Mechanisms on Diabetic Delayed Healing Wounds:Impact and Advances in Therapeutic Agents

近年来,国内糖尿病患病率逐年攀升,糖尿病性皮肤溃疡是长期糖尿病的严重并发症之一,常见于患者四肢。由于其发病机制复杂多样,导致临床治疗效果不佳,愈合困难,患者往往面临截肢和死亡风险。因此,针对糖尿病性延迟愈合伤口的血管病变机制探索以及靶向筛选治疗药物成为当前研究热点。该文就血管新生障碍和血管功能性病变在糖尿病皮肤溃疡中的作用进行简要综述,并初步总结经典降糖药物和天然化合物在抗血管病变方面的研究进展,以期为有效的临床治疗提供理论依据。

The prevalence of diabetes mellitus in China has recently been increasing year by year,and spontaneous skin ulcers in diabetic patients,as one of the most serious complications,often develop on the patient's extremities represented by foot ulcers.Due to the complexity and variety of its pathogenesis,it leads to poor clinical outcomes and difficulty in healing.Thus,patients often face the risk of amputation and death.Therefore,the exploration of mechanisms of the vascular pathogenesis of diabetic delayed-healing wounds and targeted screening of therapeutic agents has become a current research hotspot.Herein,in this paper,we briefly review the role of impaired angiogenesis and vascular dysfunction in diabetic skin ulcers,and the research progress of classical hypoglycemic and natural compounds against vascular lesions is preliminarily summarized to provide a theoretical basis for effective clinical treatment.
