摘要：目的 通过网络药理学浅究湿润烧伤膏（MEBO）治疗糖尿病足（DF）的作用机制。方法 通过中药系统药理学分析平台（TCMSP）数据库获取MEBO的活性化学成分及有效成分靶点信息，将获得靶点通过UniProt数据库统一基因名称；通过人类基因综合数据库（GeneCards）查询DF的相关靶标基因，利用Venny2.1将MEBO药物活性成分靶点与DF靶点相映射，获得潜在作用靶点。将交集靶点导入STRING网站进行分析，并使用Cytoscape3.10.0构建蛋白质-蛋白质相互作用（PPI）网络图，选出关键靶点基因。将交集靶点导入Metascape进行GO和KEGG通路富集分析，并通过Cytoscape软件构建“药物-成分-靶点”网络图。结果MEBO治疗DF的主要化学成分是小檗碱、汉黄芩素、黄麻苷A、黄连碱、黄柏酮等；关键作用靶点为表皮生长因子受体（EGFR）、一氧化氮合酶3(NOS3)、蛋白激酶B1(AKT1)、白细胞介素-1B(IL-1B)、白细胞介素-6(IL-6)、肿瘤坏死因子（TNF）等；关键作用通路为AGE-RAGE、HIF-1、VEGF、NF-κB等信号通路。结论 本研究初步揭示了MEBO的有效成分可以从多靶点、多通路治疗DF，发挥着改善微环境、抑制创面感染及促进组织修复再生等作用。

摘要：Ethnopharmacological relevance The diabetic wound is one of the common chronic complications of diabetes, which seriously affects patients’ quality of life and even causes disability and death. Traditional Chinese medicine (TCM) is a unique and precious resource in China, which has a good curative effect and safety. At present, it has been found that Chinese herbal compounds and effective active ingredients can effectively promote diabetic wound healing, and its mechanism needs to be further studied. Signaling pathways are involved in the pathogenesis and progression of diabetic wounds, which is one of the main targets for the pathologic mechanism of diabetic wounds and the pharmacological research of therapeutic drugs. Aim of the review This study has been carried out to reveal the classical signaling pathways and potential targets by the action of TCM on diabetic wound healing and provides evidence for its clinical efficacy. Materials and methods “diabetic wound”, “diabetic foot ulcer”, “traditional Chinese medicine”, “natural plant” and “medicinal plant”, were selected as the main keywords, and various online search engines, such as PubMed, Web of Science, CNKI and other publication resources, were used for searching literature. Results The results showed that TCM could regulate the signaling pathways to promote diabetic wound healing, such as Wnt, Nrf2/ARE, MAPK, PI3K/Akt, NF-κB, Notch, TGF-β/Smad, HIF-1α/VEGF, which maintaining inflammatory interaction balance, inhibiting oxidative stress and regulating abnormal glucose metabolism. Conclusion The effect of TCM on diabetic wound healing was reflected in multiple levels and multiple pathways. It is envisaged to carry out further research from precision-targeted therapy, provide ideas for screening the core target of TCM in treating diabetic wounds and create modern innovative drugs based on this target.

摘要：糖尿病性溃疡的临床发病率较高,且发病机制较为复杂、愈合过程较为缓慢,已成为临床上需要迫切解决的难题。近年来,烧伤创疡再生医疗技术(MEBT/MEBO)等中医疗法在提高糖尿病性溃疡治疗效果、降低患者截肢率方面取得了较为显著的临床疗效。但相关研究资料显示,中医药作为我国传统的治疗方式虽具有其独特的优势,可临床上仅13%的患者会在治疗过程中联合应用。为提高中医药的关注度以及指导糖尿病性溃疡的临床治疗、为MEBT/MEBO治疗糖尿病性溃疡提供理论支持,笔者通过查阅大量基础研究资料,对MEBT/MEBO通过调节PI3K/Akt信号通路、 MAPK信号通路、 Wnt/β-catenin信号通路、 TGF-β1/Smad信号通路、 NF-κB信号通路和PI3K/Akt/mTOR信号通路的转导而参与糖尿病性溃疡修复的作用机制进行了综述。

摘要：目的:探讨皮肤医疗再生技术对慢性难愈合创面组织中核因子κB(NF-κB)、NF-κB抑制蛋白(IκB)、IκB激酶(IKK)及其磷酸化蛋白表达水平的影响,来探究湿润暴露疗法/湿润烧伤膏影响慢性难愈合创面进程中是否涉及到NF-κB p65、IKK、IκBα蛋白以及磷酸化蛋白p-NF-κB p65、p-IKK、p-IκBα表达的相互作用,探讨MEBT/MEBO的部分作用机制,为临床应用MEBT/MEBO治疗慢性难愈合创面提供理论依据与技术壁垒。方法:(1)方法:选取SPF级别健康2月龄Wistar雄性大鼠,90只,体重范围235±15g,适应性喂养一周。用随机数法将90只大鼠分为5组,每组18只,分别是:空白组、对照组(急性全层皮肤缺损组)、模型组、MEBO组、贝复新组。慢性难愈合创面组包括模型组、MEBO组和贝复新组。空白组大鼠不作任何有损伤性处理;对照组大鼠行全层皮肤切除,但不注射氢化可的松;慢性难愈合创面组大鼠根据付小兵教授制备全层皮肤缺损模型结合沈氏改良塑料环肉芽肿定量法,经改进,建立大鼠慢性难愈合创面模型。所有组别除空白组外在造模后立刻用药处理。换药前,每组每天用1/5000呋西林溶液清洗两次。(2)在建立模型后的第3天、第7天、第14天分别每组麻醉6只大鼠取单侧标本,继续观察大鼠创面达到完全愈合时间,观察各组大鼠的创面情况、愈合时间及愈合率,通过HE染色观察大鼠模型创面内的炎症细胞变化及数量和Masson染色观察大鼠模型创面肉芽组织病理形态学变化、胶原蛋白的生成、组织中纤维以及炎性因子。(3)采用Western Blot检测细胞外基质成分中的NF-κB p65、IKK、IκBα蛋白以及磷酸化蛋白p-NF-κB p65、p-IKK、p-IκBα蛋白表达变化差异,观察各组受干预后对创面中NF-κB p65、IKK、IκBα蛋白以及磷酸化蛋白p-NF-κB p65、p-IKK、p-IκBα的表达的影响。(4)采用免疫荧光测定NF-κB p65入核荧光强度,间接性半定量观察炎症因子的表达趋势。结果:(1)干预第3、7天,各组大鼠创面愈合率均无明显差异(P>0.05);干预第14天,模型组大鼠创面愈合率明显低于对照组、MEBO组(P<0.05),其余各组间创面愈合率均无明显差异(P>0.05)。MEBO与对照组和贝复新组对比,创面愈合时间无明显差别(P>0.05),与模型组相比,MEBO组愈合时间明显短于模型组(P...
