               摘 要 以脂多糖诱导的小鼠脓毒症相关肾损伤(sepsis-associated kidney injury,S-AKI)模型,探究医用臭氧对 S-AKI 的治
               疗作用及机制。利用酶联免疫吸附试验、肾脏组织病理学评估、肾功能生化指标检测、免疫荧光染色及 Western blot 蛋白印迹
               分析等方法,系统检测腹腔注射臭氧对小鼠炎症,凝血和肾组织的影响。结果显示,臭氧治疗可降低                                 S-AKI 小鼠循环系统中
               的中性粒细胞胞外诱捕网(NETs)的特异性标志物(瓜氨酸化组蛋白                      H3 和髓过氧化物酶-DNA      复合物)水平,同时抑制肾
               脏组织中炎症因子及组织因子的表达。此外,臭氧还能有效改善肾脏微循环障碍,减轻肾小管损伤和间质炎症浸润,从而缓
               解  S-AKI 的病理进程。机制研究表明,臭氧通过激活              5'-一磷酸腺苷活化的蛋白激酶(AMPK)/A1 类清道夫受体(SR-
               A1)信号通路,增强巨噬细胞对组织因子富集微粒(TF-MPs)的吞噬清除能力。在                        Sr-a1 基因敲除小鼠中,臭氧的肾脏保护
               作用被完全消除,证实了        SR-A1 在该保护机制中的关键作用。综上,医用臭氧通过                 AMPK/SR-A1 信号轴促进巨噬细胞清除
               TF-NETs 复合物,发挥抗炎和改善微循环的双重保护效应,本研究为                  S-AKI 的治疗提供了新的干预靶点和治疗策略。

               Abstract    This study investigated the therapeutic effects and mechanisms of medical ozone on sepsis- associated
               kidney injury (S-AKI) induced by lipopolysaccharide in mice. Using enzyme-linked immunosorbent assay, renal
               histopathological  evaluation,  detection  of  renal  function  biochemical  indicators,  immunofluorescence  staining,
               and  Western  blot  analysis,  the  effects  of  intraperitoneal  injection  of  ozone  on  inflammation,  coagulation,  and
               renal  tissue  in  mice  were  systematically  detected.The  results  demonstrated  that  ozone  treatment  significantly
               reduced  circulating  levels  of  the  specific  markers  (citrullinated  histone  H3  and  myeloperoxidase-DNA
               complexes) from neutrophil extracellular traps (NETs) in S-AKI mice, with a suppression on inflammatory and
               tissue factor expression in renal tissue. Furthermore, ozone effectively improved microcirculation dysfunction,
               reduced  tubular  damage  and  interstitial  inflammatory  infiltration,  thereby  alleviating  pathological  changes  of
               kidneys of S-AKI mice. Mechanistic studies revealed that ozone enhances phagocytic clearance of tissue factor-
               rich microparticles (TF-MPs) by activating the 5'-monophosphate-activated protein kinase (AMPK) / scavenger
