炎症性肠病(IBD)作为一种慢性、易复发的炎症性疾病,被世界卫生组织归类为现代医疗领域的难治性疾病之一。其确切发病机制尚不清晰,目前主要认为与肠菌失衡触发宿主过度的肠黏膜免疫反应,进而在遗传易感性的个体中引发肠黏膜的损伤有关。目前,尚无特效的靶点能治愈IBD。过氧化物酶体增殖物激活受体(PPARs)作为核受体超家族的一员,在机体的生长发育、炎症调控以及代谢过程中扮演着重要角色,且被视为治疗包括IBD在内的多种疾病的重要潜在靶点,并被认为与肠道菌群关系密切。文章旨在探讨PPARs与肠道菌群的关系在IBD中的作用,从而挖掘IBD新的潜在诊疗靶点,开发新的治疗策略,为临床上IBD的诊断和治疗提供新的思路和方法。
Inflammatory bowel disease(IBD),characterized as a chronic and recurrent inflammatory condition,is classified by the World Health Organization as one of the intractable diseases in modern medicine.The precise pathogenesis of IBD remains unclear,but current research widely believes that it is closely related to dysbiosis of the gut microbiota.Imbalance in the gut flora triggers an excessive immune response in the host’s intestinal mucosa,leading to mucosal damage in genetically susceptible individuals.To date,no specific targets have been identified that can cure IBD.Peroxisome proliferator-activated receptors(PPARs),as members of the nuclear receptor superfamily,play significant roles in growth and development,inflammation regulation,and metabolic processes.They are regarded as potential effective targets for treating various diseases,including IBD,and are closely related to the gut microbiota.This review aims to discuss the progress in understanding the role of the relationship between PPARs and gut microbiota in IBD,so as to find new potential targets for the diagnosis and treatment of IBD,develop new treatment strategies,provide new ideas and methods for the diagnosis and treatment of IBD in clinical practice.

严重烧伤后患者免疫功能的失调,易导致创面感染、全身炎症反应综合征、脓毒症、感染性休克等并发症,增加患者病死率。免疫细胞功能适度的活化将有助于烧伤患者抵御外界病原体的侵袭、促进创面的愈合,但功能过度激活或者功能低下,则会引发一系列严重的后果。本文旨在归纳严重烧伤后中性粒细胞、单核/巨噬细胞、肥大细胞、NK细胞及T淋巴细胞等免疫细胞的功能变化与炎症反应之间的关系,为完善烧伤患者诊疗、减少并发症、改善预后提供新的思路。
The imbalance of immune function in severely burned patients can easily lead to wound infection,systemic inflammatory response syndrome,sepsis,septic shock and other complications,which increase the mortality of patients. Moderate activation of immune cell function will help burned patients to resist the invasion of external pathogens and promote wound healing,but excessive activation or low function can lead to a series of serious consequences. The purpose of this paper is to summarize the relationship between the functional changes of immune cells such as neutrophils,monocytes/macrophages,mast cells,NK cells,T lymphocytes and inflammatory reaction after severe burns,and to provide new ideas for improving the diagnosis and treatment of burned patients,reducing complications and improving the prognosis.
