摘要:本实验采用内毒素所致家兔弥漫性血管内凝血(DIC)模型,测定外周血白介素8(IL-8)、亚硝酸根/硝酸离子(NO-2/NO-3)水平,补体C5a活性及中性粒细胞(PMN)趋化指数,并观察MEBO对上述指标的影响。结果表明:模型组血浆IL-8、NO-2/NO-3水平及C5a活性和PMN超化指数均显著升高,其升高水平和组织、器官的损害程度相一致。MEBO及地塞米松治疗组上述指标均显著降低(P<0.01),病理组织学改变亦轻。提示:IL—8、-氧化氮(NO)参与DIC发病过程,MEBO抑制炎症反应,防止DIC的作用机理部分是通过调控细胞因子网络而实现的。
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.
