Urine sepsis is a complex inflammatory response of the body to infection with a high fatality rate. It is one of the main causes of death in noncardiovascular intensive care units. Nevertheless, in daily clinical practice, early sepsis is often not detected. In this paper, discharged cases of urinary sepsis from the Department of Urology and Critical Care Medicine of a university hospital were collected as the observation group, and common urinary tract infection cases were selected as the control group. We sorted and summarized the discharged case information of the observation group and the control group. The results of the study showed that, after renal pelvis perfusion, the expression of HMGB1 protein and mRNA increased, and the expression of TLR4 increased; inhibiting HMGB1 can reduce the expression of inflammatory factors caused by perfusion and reduce the infiltration of neutrophils and macrophages caused by perfusion. In addition, r HMGB1 treatment can promote the expression of inflammatory factors caused by perfusion and aggravate the infiltration of neutrophils and macrophages caused by perfusion. We found that inhibition of HMGB1 can inhibit the expression of TLR4/My D88 signaling molecules and r HMGB1 treatment can enhance the expression of TLR4/My D88 signaling molecules.
尿脓毒症是机体感染后发生的一种复杂的炎症反应,病死率高。它是非心血管重症监护病房死亡的主要原因之一。然而,在日常临床实践中,早期脓毒症往往无法被检测到。本文收集了某大学医院泌尿科和重症监护医学科的尿脓毒症出院病例作为观察组,并选择常见的尿路感染病例作为对照组。我们对观察组和对照组的出院病例信息进行了分类和总结。研究结果表明,肾盂灌注后,HMGB1 蛋白和 mRNA 的表达增加,TLR4 的表达增加;抑制 HMGB1 可以减少灌注引起的炎症因子的表达,并减少灌注引起的中性粒细胞和巨噬细胞的浸润。此外,rHMGB1 处理可以促进灌注引起的炎症因子的表达,并加重灌注引起的中性粒细胞和巨噬细胞的浸润。我们发现,抑制 HMGB1 可以抑制 TLR4/MyD88 信号分子的表达,而 rHMGB1 处理可以增强 TLR4/MyD88 信号分子的表达。
