研究目的:

我们研究的主要目的是探索哮喘患儿支气管肺泡灌洗液柱状上皮计数、粘液量等指标的特点,明确其在哮喘诊断中的辅助价值,从而判断BALF是否能成为哮喘的一种辅助检查方式。同时我们还希望探索支气管肺泡灌洗液柱状上皮计数与其他指标之间的相关性,从而了解哮喘发病机制中上皮损伤的上下游机制。 我们的此项研究将会为难以配合进行诱导痰等辅助检查的哮喘患儿提供一种可选的气道炎症检查方法,对这类群体的哮喘明确诊断和治疗评估有所帮助。此外,此研究还能填补当前对BALF柱状上皮比例特征和不同指标之间联系的研究空缺,帮助我们了解柱状上皮和粘液在哮喘发生和发展中所起的作用,为以后更加深入的研究打下基础。  

Objectives of Study:

The main purpose of our study was to explore the characteristics of bronchoalveolar lavage fluid columnar epithelial count and mucus volume in children with asthma, and to clarify their auxiliary value in asthma diagnosis, so as to determine whether BALF can be used as an auxiliary examination for asthma. At the same time, we also hope to explore the correlation between bronchoalveolar lavage fluid columnar epithelial count and other indicators, so as to understand the upstream and downstream mechanisms of epithelial damage in the pathogenesis of asthma. Our study will provide an alternative airway inflammation test for children with asthma who are difficult to cooperate with auxiliary tests such as sputum induction, which will be helpful for the diagnosis and treatment evaluation of asthma in this group. In addition, this study can fill the gap in the current research on the relationship between the proportion characteristics of columnar epithelium and different indicators of BALF, help us understand the role of columnar epithelium and mucus in the occurrence and progression of asthma, and lay a foundation for further research in the future.
