Therapeutic effect of autologous concentrated growth factor on lower-extremity chronic refractory wounds:A case report

BACKGROUND Management of chronic refractory wounds is one of the toughest clinical challenges for surgeons.Because of poor blood supply,less tissue coverage,and easy exposure,the lower leg is a common site for chronic refractory wounds.The current therapeutic regimens often lead to prolonged hospital stay and higher healthcare costs.Concentrated growth factor(CGF)is a novel blood extract that contains various growth factors,platelets,and fibrins to promote wound healing process.However,there has been little research reported on the treatment of lower extremity wounds with CGF.CASE SUMMARY A 37-year-old man,without any past medical history,presented an ulcerated chronic wound on his right lower leg.The skin defect exhibited clear boundaries,with a size of 2.0 cm×3.5 cm.The depth of wound was up to the layer of deep fascia.Staphylococcus aureus was detected by bacterial culture.The final diagnosis was right lower extremity ulcers with infection.Cefathiamidine,silver sulfadiazine,and mupirocin cream were applied to control the infection.CGF gel was prepared from the patient’s blood sample,and was used to cover the wound after thorough debridement.The skin wound was successfully healed after three times of CGF treatment.CONCLUSION CGF displays an excellent wound healing promoting effect in patients with lowerextremity chronic refractory wounds.

专职吞噬细胞胞葬功能在慢性创面修复中的作用机制及应用

慢性创面作为一种长期消耗性疾病,是临床上长期难以解决的难题。胞葬作用功能障碍使创面凋亡细胞不能被及时清除,继而发生细胞坏死和促炎细胞因子释放,使创面难以由炎症期向增殖期过渡。巨噬细胞和树突状细胞作为专职的吞噬细胞,是胞葬作用的主要承担者,本文通过对两种专职吞噬细胞参与创面愈合过程的作用机理进行综述,发现除胞葬相关作用受体外,巨噬细胞和树突状细胞还分别通过作用于ICAM‑1、NK‑4,MIR‑21、CD36等信号分子发挥胞葬作用,加速慢性创面的愈合。此外,树突状细胞的胞葬功能可能会受到SLC7A11的限制,去除或抑制SLC7A11可以显著增强树突状细胞的胞葬作用促进慢性创面愈合,本研究对进一步阐明慢性创面的愈合过程和创新治疗措施具有重要意义。

MEBT/MEBO治疗慢性难愈合创面作用机制研究进展

慢性难愈合创面具有高致残率、高致死率等特点,给患者造成了极大的痛苦。近年来,创疡再生医疗技术(MEBT/MEBO)因能够通过调控创面再生修复过程中的炎症反应、细胞增殖和组织重塑等阶段促进肉芽组织生长、血管生成、上皮组织移行等而加快创面愈合,被广泛应用于慢性难愈合创面的临床治疗。基于此,本文主要对MEBT/MEBO调控炎症反应、细胞增殖和组织重塑3个阶段促进慢性难愈合创面修复的相关机制予以综述,以期为MEBT/MEBO的进一步临床应用提供理论依据及思路。
