研究目的: |
高血压肾病是导致终末期肾病的重要诱因,对患者健康和公共卫生构成了重大威胁。然而,其具体发病机制尚未完全阐明,代谢物在高血压肾病进展中的作用仍不清晰。在此前研究中,本团队基于单中心临床样本建立了尿液代谢组学高通量质谱平台,初步验证了代谢组在高血压肾病诊断中的优异表现,为本研究的多中心扩展奠定了基础。在本研究中,我们将进一步开展多中心大样本量横断面研究,通过尿液代谢组学构建高血压肾病的特征代谢指纹,并结合AI算法筛选关键代谢标志物。接下来,我们将利用肾脏组织的空间代谢组学技术和细胞实验,验证筛选标志物的空间分布及其功能,进一步探究其在高血压肾病中的调控机制。本研究旨在揭示高血压肾病的代谢标志物代谢图谱,为后续的临床转化和早期诊断方法的开发奠定科学基础。 |

Objectives of Study: |
Hypertensive nephropathy is an important cause of end-stage renal disease, posing a significant threat to the health of patients and public health. However, its specific pathogenesis has not been fully elucidated, and the role of metabolites in the progression of hypertensive nephropathy is still unclear. In previous studies, our team established a high-throughput mass spectrometry platform for urine metabolomics based on single center clinical samples, which preliminarily verified the excellent performance of metabolomics in the diagnosis of hypertensive nephropathy, laying the foundation for the multi center expansion of this study. In this study, we will further conduct a multi center large sample cross-sectional study, construct characteristic metabolic fingerprints of hypertensive nephropathy through urine metabolomics, and screen key metabolic markers using AI algorithms. Next, we will use spatial metabolomics techniques and cellular experiments of kidney tissue to verify the spatial distribution and function of screening biomarkers, and further explore their regulatory mechanisms in hypertensive nephropathy. The aim of this study is to reveal the metabolic profile of metabolic markers in hypertensive nephropathy, laying a scientific foundation for subsequent clinical translation and the development of early diagnostic methods. |
