Human intestinal absorption (HIA) is a crucial indicator for measuring the oral bioavailability of drugs.This study aims to use artificial intelligence methods to predict and evaluate the HIA of drugs in the early stages of drug discovery, thus accelerating the drug discovery process and reducing costs.This study used MOE''s 2D, 3D descriptors, and ECFP4 (extended connectivity fingerprints) to characterize the molecules and established eight models, including support vector machine (SVM), random forest (RF), and deep neural network (DNN).The results showed that the SVM model constructed using a combination of 2D, 3D descriptors and ECFP4 fingerprints was the optimal model according to comprehensive evaluation of various evaluation indicators.The area under the receiver operating characteristic curve (AUC), Matthews correlation coefficient, and Kappa coefficient of the optimal model were 0.94, 0.75, and 0.74, respectively.In conclusion, this study established a robust and generalizable machine learning model for predicting HIA properties, which can provide guidance for early molecular screening and the study of pharmacokinetic properties of drugs.

The construction of "New Medicine" is the leader of the innovative development of medical education in China in the new era. Strengthening the cross-integration of medicine and science is helpful to promote the training of top-notch interdisciplinary innovative talents under the multidisciplinary background of "Medicine + X". The applied psychology major in medical colleges has unique advantages in education and teaching resources. How to combine the advantages to construct the education model of the integration of medicine and science is still in the exploration stage. This paper analyzes the current situation of talent training of the applied psychology major in medical colleges and the new requirements for discipline-major construction under the background of "New Medicine" construction, demonstrates the measures to strengthen the deep integration of medicine and science from the aspects of curriculum system setting, teacher team construction, practice teaching, and teaching method reform, and puts forward the innovative education model of the integration of medicine and science in applied psychology-medicine interdisciplinary training.
