摘要
Traffic accidents,high-altitude drops,mechani cal shock and other accidents may lead to human spinal cord injury,interrupting the transmission channel of human nerve signals,resulting in loss of some limb function.Since there is no method of spinal cord injury site of nerve cell act ivity,while the conventional testing instruments such as X ray,CT and other tr aditional instruments cannot provide any nerve cell activity,doctors couldn't have a clearer understanding of the patient's condition,which may delay the be s t timing of treatment,thus causing lifelong paralysis.Spectroscopy method can be used in the detection of cell organization change while near infrared spectru m technology is a kind of fast measurement and simple operation of nondestructiv e measuring.Therefore,aiming at the shortcomings of the existing medical testi ng equipment,on the basis of animal experiment,this paper uses near infrared s pectrum technology,based on the absorption characteristics of the material in n ear infrared wave band,and combined with near infrared spectrum analysis techni que of qualitative determination and quantitative analysis of the characteristic s.Using clustering algorithm for spinal cord injury site of neuron-specific nu clear protein and neurotransmitters classify and simulation,partial least squar es (PLS) algorithm is used to calculate the content to achieve a spinal cord acc urate detection of the site of injury nerve cell activity.This method provides theoretical basis for the detection of spinal cord injury,bringing hopes to pat ients with limb function reconstruction and rehabilitation,for clinical provide s a method to detect the activity of nerve cells in the noninvasive.
