| Objective: To analyze and summarize the common risk factors of lumbar disc herniation.To establishment the discrimination regression equation for L4/5 disc herniation diagnosis.Based on the theory about image-based nodal classification method of disc herniation from Hu Yougu that to establishment the discrimination regression equation for discriminanting common Hu yougu herniation area of L4/5 disc herniation.Not only to observe occurrence regularity of lumbar disc herniation but also to find out a discrimination method that is non-invasive,fast,safety,reality and reliable which convenient for clinical expansion.Methods: Selecting 63 patients which had been clear diagnosis L4/5discherniation according to Lumbar CT or MRI image by theirselves and 30 healthy from The First Affiliated Hospital of Guangxi University of traditional Chinese Medicine,Ruikang Affiliated Hospital of Guangxi University of traditional Chinese medicine,Guangxi Zhuang autonomous region national hospital,The people's hospital of guangxi zhuang autonomous region.Questionnaire survey use the some questionnaire.Using correlation regression analysis method to analyze and summarize the common risk factors of lumbar disc herniation.Using Fisher discriminant analysis method to establishment the discrimination regression equation for L4/5 disc herniation diagnosis.Based on the theory about image-based nodal classification method of disc herniation from Hu Yougu that to establishment the discrimination regression equation for discriminanting common Hu yougu herniation area of L4/5 disc herniation.Results: 1.The correlation analysis revealed that age,professional nature,cultural level,the history of waist injury,the history of chronic illness are significant correlation with L4/5 disc herniation on the 0.01 level.The positive correlation between L4/5 disc herniation and age,cultural level,the history of waist injury,the history of chronic illness.The negative correlation between L4/5 disc herniation and professional nature.2.Establishment the discrimination regression equation for L4/5 disc herniation diagnosis:(1)Y0=6.722x5+23.033x20+28.125x24+2.48x25-8.283x26+10.17x27+65.757x28-5.673x29+20.574x31-7.428x51-68.016(2)Y1=-15.004x5+123.927x20+91.337x24+94.474x25-62.633x26-2.705x27+195.484x28-79.311x29+79.629x31-50.312x51-320.47Substitute the factor x into two models and calculate,if Y0>Y1,then this patient belongs to no L4/5 disc herniation.If not,this patient belongs to L4/5 disc herniation.3.Establishment the discrimination regression equation for discriminanting common Hu yougu herniation area of L4/5 disc herniation:(1)Y1=0.849x2+8.709x4+1.426x6+1.289x7+19.196x8+14.794x9-22.264x10+15.134x12+10.739x14+11.184x17+24.003x18-30.402x20+17.5x24-3.25x26-5.352x27-17.996x29+15.941x32+22.249x42+23.103x47+14.184x52-212.847(2)Y2=0.946x2+3.784x4+2.715x6+1.098x7+19.996x8+14.474x9-20.313x10+16.206x12+4.861x14+13.09x17+22.564x18-30.989x20+13.041x24-2.272x26-1.988x27-14.541x29+10.591x32+23.734x42+23.606x47+11.316x52-209.593(3)Y3=1.061x2+3.443x4+2.415x6+1.064x7+19.958x8+12.454x9-18.64x10+17.314x12+2.939x14+16.374x17+22.091x18-27.526x20+13.725x24-1.884x26-4.276x27-15.853x29+7.469x32+26.342x42+22.903x47+13.945x52-206.834(4)Y4=1.153x2+3.674x4+2.686x6+1.134x7+24.858x8+13.939x9-26.254x10+16.41x12+4.322x14+15.407x17+22.024x18-30.273x20+14.759x24-2.934x26-4.631x27-15.477x29+7.425x32+27.273x42+25.951x47+14.122x52-228.857(5)Y5=1.025x2+5.022x4+2.811x6+0.978x7+23.851x8+12.735x9-26.235x10+17.478x12+5.569x14+12.859x17+23.651x18-28.943x20+16.857x24-2.896x26-4.739x27-16.931x29+8.302x32+26.466x42+26.871x47+12.188x52-214.161Substitute the factor x into five models and calculate,and then comparing the result of Y1,Y2,Y3,Y4,Y5,the max one belongs to which the type of Hu yougu herniation area is Y expression.Conclusions:1.L4/5 disc herniation's common risks are age,professional nature,cultural level,the history of waist injury and the history of chronic illness.2.The result of discrimination regression equation for L4/5 disc herniation diagnosis support discrimination L4/5 disc herniation diagnosis.The test result of function model is satisfactory.It is one of important reference in discriminant L4/5 disc herniation.3.The accuracy of the discrimination regression equation for L4/5disc herniation diagnosis is low.The reasons may correlate with the different pathological nature of sequestrated tissue or the different compensatory capacity of spinal canal or the different ability of nerve root compressed what makes degree of nerve root compressed no equivalence with degree of clinical symptoms and signs.It remains to further investigation. |
