概括
人工智能 (AI) 光方法在检测精子DNA碎片化指数 (DFI) 方面具有较高的特异性,与流细胞计相比,在寡精子症 (OS) 患者中. 当精子度低于10×106/ml时,AI更适合用于OS检测.
科学领域:
- 生殖生物学 生殖生物学
- 医疗技术 医疗技术 医学技术
- 精子分析 精子分析
背景情况:
- 寡精症 (OS) 是一种以低精子度为特征的疾病,可能会影响男性生育能力.
- 精子DNA碎片化指数 (DFI) 是精子DNA完整性的标志物,对于评估男性生殖健康至关重要.
- 精确检测DFI对于诊断和管理男性不孕症至关重要.
研究的目的:
- 评估人工智能 (AI) 光方法用于检测精子DNA碎片化指数 (DFI) 在患有小精子症 (OS) 的男性中的有效性.
- 在各种精子度组中,将AI光方法与传统的流动细胞计 (精子染色体结构测定 - SCSA) 进行比较.
主要方法:
- 从201名男性收集的精液样本:50名阿佐精子 (AS),90名OS和61名正常对照.
- 将OS患者分为轻度,中度和重度/极度重度的组 (30个).
- 将AI光和流细胞计之间的DFI检测结果进行比较.
主要成果:
- 人工智能光法显示,与AS,中度OS和严重/极度严重OS组的流动细胞计相比,DFI检测具有统计学意义的差异 (P<0.01).
- 人工智能光方法在AS患者中产生较低的DFI值和较低的非0结果率 (8%vs100%).
- 在正常和轻度OS组 (R2=0.7470,R2=0.7180) 中观察到AI和DFI流细胞计之间的良好线性相关性,但在中度和重度OS组 (R2<0.36) 中的相关性较差.
结论:
- 与流细胞计相比,AI光法在寡精子症患者中对DFI检测具有更高的特异性和适用性.
- 当精子度≥10×106/ml时,观察到方法之间的DFI值的一致性.
- 当精子度在>0×106/ml和<10×106/ml之间时,检测准确度可能会受到影响.

Flow Cytometry

The development of flow cytometry techniques began in 1934 with initial attempts by Andrew Moldavan, a bacteriologist who counted the cells in a flowing capillary system. Moldavan pumped cells through a capillary tube focused under a microscope for visualization. The invention of photometry allowed the measurement of differentially-stained cells, and Louis Kamentsky developed the first multiparameter flow cytometer in 1965 to identify and count the cancer cells in cervical tissue specimens.

Immunofluorescence Microscopy
11.3K
A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.
