Based on the limitations of certain conditions in the traditional clinical pathology teaching, this paper puts forward the "quaternity" hybrid digital teaching reform practice of clinical medicine, imaging, anatomy and pathology content. This teaching method can optimize the teaching process and improve the teaching efficiency. The specific advantages of this teaching method are as follows: the digital materials of different modules of clinical practice, imaging, anatomy and pathology are integrated to make the teaching content more perfect; it is helpful to improve the cognition of resident doctors on the pathological characteristics and the overall characteristics of the disease, and promote their thinking ability of clinicopathological integration; the combination of hybrid digital teaching and various teaching methods, including clinical pathology discussion, makes teaching more free and is conducive to classroom learning and self-learning. This paper discussed the construction and application of the "quaternity " hybrid digital teaching mode, and provided new ideas and methods for clinical pathology teaching and talent training.
