目的 利用人工神经网络对新疆维吾尔族癫痫患儿奥卡西平稳态血清药物浓度进行预测,为临床奥卡西平个体化给药提供理论依据。 方法 测定270例新疆维吾尔自治区人民医院维吾尔族癫痫患儿奥卡西平稳态血清药物浓度,提取相关数据,采用Matlab(R2018a) 编程软件,结合深度学习网络构建奥卡西平血药浓度预测模型。 结果 模型建立的网络参数为:初始学习率为0.001,最终学习率为0.000 1,动量系数为0.90,最大训练次数为1 000,遗传代数为6 000,其他参数为默认值。模型验证结果显示,45例维吾尔族癫痫患儿奥卡西平血清谷浓度中,45个浓度预测误差均小于10%,误差小于15%的比率是100.00%,平均预测误差(MPE)为0.01%,平均预测绝对误差(MAE)为1.21%。预测的血药浓度和实际测定浓度之间的相关系数为0.997,预测结果较理想。结论 应用人工神经网络预测新疆地区维吾尔族癫痫患儿奥卡西平血清药物浓度是可行的,可将其用于奥卡西平个体化给药的研究,促进临床合理用药。
Abstract
OBJECTIVE To predict the steady-state serum concentration of oxcarbazepine in Uygur children with epilepsy in Xinjiang by artificial neural network, thus to provide a theoretical basis for individualized administration of oxcarbazepine. METHODS The steady-state serum concentration of oxcarbazepine was measured in 270 Uygur children with epilepsy in the People's Hospital of Xinjiang Uygur Autonomous Region, and the relevant data was extracted. The prediction model of plasma concentration of oxcarbazepine was constructed by using Matlab (R2018a) programming software and deep learning network. RESULTS The network parameters of the model were as follows: the initial learning rate was 0.001, the final learning rate was 0.000 1, the momentum coefficient was 0.90, the maximum training times was 1 000, the genetic algebra was 6 000, and the other parameters were default values. The results of model verification showed that among the 45 Uygur children with epilepsy, the prediction errors of 45 oxcarbazepine serum trough concentrations were all less than 10%, and the rate of error of less than 15% was 100.00%. The mean prediction error(MPE) was 0.01% and the mean absolute prediction error(MAE) was 1.21%. The correlation coefficient between the predicted blood concentration and the actual determined concentration was 0.997, and the predicted result was ideal. CONCLUSION It is feasible to use artificial neural network to predict the serum concentration of oxcarbazepine in Uygur children with epilepsy in Xinjiang. It can be used in the study of individual administration of oxcarbazepine to promote the rational use of oxcarbazepine in clinic.
