研究目的:

本研究围绕肺炎支原体肺炎(MPP)患儿气道高反应的临床问题,结合miRNA调控免疫炎症通路的研究背景,旨在达成以下核心目的: 1.?明确表达关联:通过临床样本检测,量化MPP患儿(试验组)与支气管异物患儿(对照组)支气管肺泡灌洗液(BALF)及外周血中miR-21、IL-2/STAT5通路关键因子(IL-2、STAT5、IL-6、IL-10、IL-17、TGF-β)的表达水平,验证miR-21与IL-2、STAT5表达的相关性,为通路调控关系提供临床数据支撑。 2.?解析机制作用: 借助SPF级BALB/c小鼠构建MPP模型,通过分组干预(正常组、模型组、miR-21模拟物组、miR-21抑制剂组、miR-21模拟物+IL-2/STAT5抑制剂组),结合气道高反应性测定、肺组织病理观察、炎性因子检测(ELISA)、基因表达分析(qPCR)及蛋白检测(WB),明确miR-21是否通过调控IL-2/STAT5通路影响免疫炎症反应(如Th17/Treg平衡),进而诱发或加重MPP患儿气道高反应。 3.?提供临床与研发依据: 基于上述机制研究结果,为MPP患儿气道高反应的预后评估提供潜在生物学标志物(如miR-21、STAT5),同时为开发针对miR-21或IL-2/STAT5通路的MPP气道高反应靶向治疗药物(如miR-21抑制剂)提供理论基础,填补当前MPP气道高反应分子机制研究的空白。  

Objectives of Study:

1.?Clarify the expression correlation Quantify the expression levels of miR-21 and key factors of the IL-2/STAT5 pathway (IL-2, STAT5, IL-6, IL-10, IL-17, TGF-β) in bronchoalveolar lavage fluid (BALF) and peripheral blood of children with Mycoplasma pneumoniae pneumonia (MPP, experimental group) and children with bronchial foreign bodies (control group) through clinical sample detection. Verify the correlation between miR-21 and the expression of IL-2/STAT5, so as to provide clinical data support for the regulatory relationship of the pathway. 2.?Analyze the mechanism of action Construct an MPP model using SPF-grade BALB/c mice, and conduct grouped interventions (normal group, model group, miR-21 mimic group, miR-21 inhibitor group, miR-21 mimic + IL-2/STAT5 inhibitor group). Combine airway hyperresponsiveness measurement, lung tissue pathological observation, inflammatory factor detection (ELISA), gene expression analysis (qPCR) and protein detection (WB) to clarify whether miR-21 affects immune-inflammatory responses (such as Th17/Treg balance) by regulating the IL-2/STAT5 pathway, thereby inducing or aggravating airway hyperresponsiveness in children with MPP. 3.?Provide clinical and research and development basis Based on the research results of the aforementioned mechanisms, this study provides potential biomarkers (such as miR-21 and STAT5) for the prognostic assessment of airway hyperresponsiveness in children with MPP, and lays a theoretical foundation for the development of targeted therapeutic drugs (such as miR-21 inhibitors) for airway hyperresponsiveness in MPP targeting the miR-21 or IL-2/STAT5 pathway, filling the current gap in the molecular mechanism research of airway hyperresponsiveness in MPP.
