摘要: 皮肤自体荧光是由组织内多种内源性荧光物质在被激发后所产生的相互叠加的荧光, 可预示相关疾病的发生。然而, 内源性荧光团之间的光谱重叠会对目标检测造成干扰, 因此选择合适的检测光波长有助于提高识别效果。本研究选取晚期糖基化终末产物(AGEs)、还原型烟酰胺腺嘌呤二核苷酸(NADH)、黄素腺嘌呤二核苷酸(FAD)以及胶原蛋白(COL)作为实验对象, 首先构建了三维荧光光谱数据库。随后, 通过区域积分法提取了四种荧光物质的特征区域, 并结合无信息变量消除法进一步筛选出178个特征波长。最后, 基于多元线性回归建立校正曲线, 计算了各荧光物质的回收率。结果表明, AGEs、NADH、FAD和COL的回收率范围分别为70%~110%、80%~110%、70%~130%和50%~190%, 基于178个特征波长建立的模型对AGEs、NADH和FAD的预测效果较好, 实现了对重叠光谱中此三种荧光物质的高选择性波长筛选。

Abstract: Skin autofluorescence arises from the superposition of various endogenous fluorophores in tissues upon excitation, serving as an indicator of related disease states. However, spectral overlap among endogenous fluorophores complicates the detection of specific targets, so selecting optimal detection wavelengths can enhance the identification effectiveness of these targets. Advanced glycation end products (AGEs), reduced niacinamide adenine dinucleotide (NADH), flavin adenine dinucleotide (FAD) and collagen (COL) were selected as experimental subjects in this work. Firstly, a database of overlapping three-dimensional fluorescence spectra of the four fluorescent substances were constructed. Then, the characteristic regions of the four fluorescent substances were identified using the region integration method, and 178 characteristic wavelengths were selected through the elimination of uninformative variables. Finally, a calibration curve was established based on multiple linear regression, and the recovery rates of each fluorescent substance were calculated. The results showed that the recovery rates of AGEs, NADH, FAD, and COL were 70%–110%, 80%–110%, 70%–130%, and 50%–190%, respectively, and the predictive accuracy for AGEs, NADH, and FAD of the model based on 178 characteristic wavelengths was acceptable, achieving highly selective screening of detection wavelengths for the three fluorescent substances in overlapping spectra.
