研究目的: |
(1)通过对老年重症肺炎患者有无并发急性呼吸窘迫综合征(ARDS)的不同组别与疾病严重程度及治疗方式和死亡关联的研究,使临床医生能更准确地掌握其对预后的影响因素,以此指导临床抢救和治疗工作,进一步完善对ARDS患者的治疗及治疗策略,为提高抢救成功率、降低死亡率开辟新的思路和平台。 (2)基于GEO数据库及临床样本验证miR-202-5p在ARDS患者外泌体中的差异表达情况,并分析其与临床表型以及预后的相关性。通过体内外实验验证外泌体miR-202-5p通过调控内皮细胞通透性,促进ARDS损伤的生物学功能; (3)探讨miR-202-5p调控内皮细胞通透性的下游靶通路,揭示miR-202-5p通过靶基因MARCH6调控内皮细胞通透性,进而影响ARDS的炎症损伤的分子机制。 (4)进一步分析miR-202-5p/ MARCH6与炎症反应指标(Ang-2、sICAM-1、VEGF、vWF)在ARDS中的可能相关性及是否为独立危险因素。 (5)本研究想进一步阐述证明ARDS患者中血清外泌体源性miR-202-5p减少,下调了对靶基因MARCH6的抑制作用,进而促进了内皮细胞通透性,促进ARDS的炎症损伤,与炎症因子有关联,为ARDS的临床基础研究寻找潜在的靶点(如miR-202-5p作为早期诊断靶点,而MARCH6可作为治疗靶点研制抑制剂等),提供新的理论依据。 |

Objectives of Study: |
(1) By studying the association between different groups of elderly patients with severe pneumonia and acute respiratory distress syndrome (ARDS), disease severity, treatment methods, and mortality, clinical doctors can more accurately grasp the factors that affect prognosis, guide clinical rescue and treatment work, further improve the treatment and treatment strategies for ARDS patients, and open up new ideas and platforms for improving rescue success rates and reducing mortality rates. (2) Verify the differential expression of miR-202-5p in extracellular vesicles of ARDS patients based on GEO database and clinical samples, and analyze its correlation with clinical phenotype and prognosis. Verify the biological function of extracellular vesicle miR-202-5p in promoting ARDS injury by regulating endothelial cell permeability through in vitro and in vivo experiments; (3) Exploring the downstream target pathways of miR-202-5p in regulating endothelial cell permeability, revealing the molecular mechanism by which miR-202-5p regulates endothelial cell permeability through the target gene MARCH6, thereby affecting inflammatory damage in ARDS. (4) Further analyze the possible correlation between miR-202-5p/MARCH6 and inflammatory response markers (Ang-2, sICAM-1, VEGF, vWF) in ARDS and whether they are independent risk factors. (5) This study aims to further elucidate the evidence that serum exosome derived miR-202-5p is reduced in ARDS patients, downregulating the inhibitory effect on the target gene MARCH6, thereby promoting endothelial cell permeability and facilitating inflammatory damage in ARDS. It is associated with inflammatory factors and provides new theoretical basis for the clinical basic research of ARDS to find potential targets (such as miR-202-5p as an early diagnostic target, while MARCH6 can be used as a therapeutic target to develop inhibitors, etc.). |
