用深度学习分析全血凝固情况,对比新型抗凝剂效果

Deep Learning-Enhanced Analysis for Delineating Anticoagulant Essay Efficacy Using Phase Microscopy

  • 结合数字全息显微镜与深度学习,无标记检测血细胞形态
  • 6小时内EDTA改变红细胞形态,而KFeOx-NPs无影响
  • 适合血液检测、抗凝剂研发人员快速评估凝固抑制效果

采血后血液凝固严重影响血液学分析,可能导致结果偏差和细胞特征改变。本文提出一种基于数字全息显微镜(DHM)的深度学习增强框架,用于体外评估抗凝剂效能。该方法无需标记、非侵入式,可准确计数血细胞并估计形态变化。构建了自动化图像处理与深度学习流程,分析两种抗凝剂(传统EDTA与新型铁酸钾草酸盐纳米颗粒KFeOx-NPs)处理下的血细胞形态。结果表明,KFeOx-NPs在6小时内有效防止人类血液凝固且不改变红细胞形态,而EDTA处理导致显著形态变化。系统通过评估细胞聚集度和形态随时间变化,实现凝固动力学的定量分析,为体外抗凝剂比较提供新方法。

原文摘要 · Abstract (English)

The coagulation of blood after it is drawn from the body poses a significant challenge for hematological analysis, potentially leading to inaccurate test results and altered cellular characteristics, compromising diagnostic reliability. This paper presents a deep learning-enhanced framework for delineating anticoagulant efficacy ex vivo using Digital Holographic Microscopy (DHM). We demonstrate a label-free, non-invasive approach for analyzing human blood samples, capable of accurate cell counting and morphological estimation. A DHM with an automated image processing and deep learning pipeline is built for morphological analysis of the blood cells under two different anti-coagulation agents, e.g. conventional EDTA and novel potassium ferric oxalate nanoparticles (KFeOx-NPs). This enables automated high-throughput screening of cells and estimation of blood coagulation rates when samples are treated with different anticoagulants. Results indicated that KFeOx-NPs prevented human blood coagulation without altering the cellular morphology of red blood cells (RBCs), whereas EDTA incubation caused notable changes within 6 hours of incubation. The system allows for quantitative analysis of coagulation dynamics by assessing parameters like cell clustering and morphology over time in these prepared samples, offering insights into the comparative efficacy and effects of anticoagulants outside the body.
