近红外光谱和聚类分析法快速鉴别神经束性质的初步研究

Preliminary research of indentifying the property of nerve fiber by near-infrared spectroscopy and cluster analysis

目的:初步研究近红外光谱分析法在鉴别周围神经运动束和感觉束的应用,探讨建立一种快速鉴别周围神经束性质的方法。方法:取Beagle犬的脊神经前根和后根(前根为运动神经,后根为感觉神经),利用近红外漫透射方式进行快速采样,并以它们的近红外吸收图谱用光谱模式识别法中的聚类分析法进行定性分类鉴别。结果:脊神经的前根和后根其一二阶导数光谱较为相近,不能直观进行鉴别;经聚类分析可以将前根和后根归为两类,达到直观鉴别的目的。结论:近红外光谱分析技术有可能成为一种快速鉴别周围神经束性质的方法。

Objective：To provide a rapid method for identifying motor and sensory fiber. Methods： Near-infrared spectroscopy （NIRS）was used for rapid collection of numerical data about the anterior and posterior nerve roots of the Beagles, then cluster analysis of the pattern recognition was adopted. Results： The results showed that the anterior and posterior roots had quite similar firstderivative and second-derivative spectra of the near-infrared spectroscopy and were unable to be distinguished. Different Spinal nerve roots of the Beagles could be distinguished by cluster analysis. Conclusion： The near-infrared spectroscopy and cluster analysis may be a good methods to quickly identify the property of nerve fiber.
