研究目的:

肾脏微循环由动脉微血管、静脉微血管和毛细血管网组成,主要负责代谢废物清除、血压调节和电解质平衡维持,但其结构和功能易受缺血、缺氧等病理条件影响,导致功能障碍 。在糖尿病肾病(DKD)中,肾微循环的病理变化包括微血管结构重塑、内皮功能障碍及血流动力学失衡,这些变化加速了疾病进展 。此外,肾移植后慢性肾小球滤过功能不全时,移植肾皮质微循环血流灌注特征可直接反映肾小球血流灌注的病理变化,实时监测其微循环灌注特征具有重要临床价值 。 近年来,多种先进技术如超声定位显微技术、功能磁共振成像(如动脉自旋标记灌注成像和血氧水平依赖成像)以及多光子显微镜技术,已被用于肾脏血流动力学和氧代谢的定量评估 。然而,现有技术仍面临分辨率不足、造影剂限制等问题,构建“多组学-空间活体成像-人工智能”一体化诊疗平台成为未来发展的关键。 2021年国际管理指南同样建议将感染性休克患者MAP提高到65毫米汞柱以上,且大量RCT实验说明更高的MAP并不能提高脓毒症患者生存率。[6]2000年一项研究表明用去甲肾上腺素将MAP从65毫米汞柱增加到75毫米汞柱显示尿量是增加的。2007年发表在ICM上一篇文献表明随着目标MAP增加至75mmHg,肾脏阻力指数显著下降,尿量有所提升,说明一定程度提高MAP对肾脏是有益的。[8]但是增加MAP对肾脏血流动力学、肾脏微循环影响的相关研究是很少的。因此,成为此次研究主要目的。  

Objectives of Study:

The microcirculation of the kidneys is composed of arterial microvessels, venous microvessels and a capillary network. It is mainly responsible for the clearance of metabolic wastes, blood pressure regulation and the maintenance of electrolyte balance. However, its structure and function are easily affected by pathological conditions such as ischemia and hypoxia, leading to functional disorders. In diabetic nephropathy (DKD), the pathological changes of renal microcirculation include microvascular structure remodeling, endothelial dysfunction and hemodynamic imbalance, which accelerate the progression of the disease. In addition, when there is chronic glomerular filtration insufficiency after kidney transplantation, the microcirculation blood perfusion characteristics of the transplanted renal cortex can directly reflect the pathological changes of glomerular blood perfusion. Real-time monitoring of its microcirculation perfusion characteristics has important clinical value. In recent years, a variety of advanced techniques such as ultrasound localization microscopy, functional magnetic resonance imaging (such as arterial spin-labeled perfusion imaging and blood oxygen level-dependent imaging), and multi-photon microscopy have been applied to the quantitative assessment of renal hemodynamics and oxygen metabolism. However, the existing technology still faces problems such as insufficient resolution and contrast agent limitations. Building an integrated diagnosis
