研究目的: |
探讨肥胖与哮喘之间的临床关联,并进一步评估肺组织中VNN1与HIF-1表达升高在肥胖相关哮喘中的作用,结合临床病例分析与肺组织样本验证,从流行病学关联和组织分子机制两个层面,为肥胖哮喘的发生发展机制提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study explores the clinical correlation between obesity and asthma, and further assesses the role of increased expression of VNN1 and HIF-1 in lung tissue in obesity-related asthma. By combining clinical case analysis and lung tissue sample verification, it provides evidence from both epidemiological association and tissue molecular mechanism perspectives to elucidate the pathogenesis of obesity-related asthma. |

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC: |
数据采集:临床回顾性研究,收集2010–2026年广州中医药大学第一附属医院住院哮喘患者病史资料包括收集年龄、分期、治疗方案等。数据来自电子病历系统,双人录入Excel。 在同院同期接受肺切除手术的患者中,收集非哮喘对照、单纯肥胖、单纯哮喘及肥胖合并哮喘患者的肺组织样本及临床资料。采用免疫组化、qPCR 或 Western blot 等方法检测肺组织中 VNN1 和 HIF-1α表达水平,比较四组间差异,并分析其与 BMI、哮喘病史、影像学特征及炎症指标之间的关系,以验证第一部分临床研究发现并探讨潜在机制。 数据管理:原始数据双人录入Excel,进行范围检查和逻辑核查;保存为加密文件,仅授权人员访问;患者信息去标识化处理。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection: This was a retrospective clinical study that collected medical records of inpatients with asthma at the First Affiliated Hospital of Guangzhou University of Chinese Medicine between 2010 and 2026, including data on age, disease stage, and treatment regimens. Data were retrieved from the electronic medical records system and entered into Excel by two researchers. Among patients who underwent lung resection at the same hospital during the same period, lung tissue samples and clinical data were collected from non-asthmatic controls, patients with obesity alone, patients with asthma alone, and patients with obesity and asthma. Methods such as immunohistochemistry, qPCR, and Western blot were employed to detect the expression levels of VNN1 and HIF-1α in lung tissue. Differences between the four groups were compared, and their relationships with BMI, asthma history, radiological features, and inflammatory markers were analysed to validate the findings from the first part of the clinical study and explore potential mechanisms. Data management: Raw data were entered into Excel by two independent operators, followed by range checks and logical verification; data were saved as encrypted files accessible only to authorised personnel; patient information was de-identified. |
