研究目的: |
本研究以年龄≥65 岁的老年维持性血液透析患者为研究对象,利用磁共振采集胸部随呼吸运动的动态影像、制作动态电影,随后对磁共振电影图像分割得到动态肺部 Mask 图像,通过计算机深度学习建模,评估老年血液透析患者膈肌结构和功能指标,定量该人群膈肌功能状况。以心血管不良事件和死亡为终点事件构建风险预测模型并进行模型验证。通过体外实验初步探讨 HIF-1α是否通过BNIP3介导线粒体自噬,从而导致膈肌萎缩。该研究为评估老年维持性血液透析人群的膈肌功能提供具体参考,并初步探索其可能的分子机制,便于早期发现高危患者、早期干预,以降低其心血管不良事件的发生率和死亡率,改善患者生活质量,大大减少医疗支出。 |

Objectives of Study: |
In this study, elderly maintenance hemodialysis patients aged >= 65 years were screened as the research objects. Dynamic images of chest movement with breathing were collected by magnetic resonance images and dynamic movies were made. Then dynamic lung Mask images were obtained by segmentation of magnetic resonance images, and the structure and function indexes of diaphragm were evaluated by deep learning. The diaphragm function of the population was quantified. A risk prediction model with cardiovascular adverse events and death as endpoints was constructed and verified. In vitro experiments were conducted to investigate whether HIF-1α leads to diaphragmatic atrophy through mitochondrial autophagy mediated by BNIP3. This study provides specific reference for assessing diaphragm function in elderly maintenance hemodialysis patients and preliminarily explores its possible molecular mechanism, to facilitate early detection and early intervention of high-risk patients of diaphragm dysfunction,to reduce the incidence and mortality of cardiovascular adverse events, and to improve patients' quality of life and reduce medical expenditure. |
