病理学是用自然科学的方法研究疾病的病因、发病机理以及疾病时细胞、组织和器官的结构和功能变化及其演变规律，从而阐明疾病本质的一门学科。它既是一门基础学科，同时又是一门实践性很强的具有临床性质的学科，长期以来成为基础医学和临床医学之间的“桥梁”课程，为认识疾病和防治疾病提供理论基础。病理学通过尸体解剖和活组织检查为临床各科对疾病的诊断提供重要依据，病理诊断被认为是带有宣判性质的、权威性的诊断，所以美国著名医生和医学史专家William Osler称“病理学为医学之本”，病理医生被认为是“医生的医生”。病理学课程包括理论课及实验课，二者相互联系，加深对病理学理论知识的理解和掌握，加强知识运用能力的培养。 病理学课程内容分为病理学总论（又称普通病理学）及病理学各论（又称系统病理学）两部分。总论所研究和阐述的是细胞和组织的适应和损伤、损伤的修复、局部血液循环障碍、炎症和肿瘤等基本病理变化，是各种不同疾病发生发展的共同规律。而各论是在总论学习的基础上，研究和阐述各种不同疾病的特殊规律。 “病理为医学之本”（William Osler）。我们坚信优秀的临床医师一定具有坚实的病理学知识。我们面向未来，努力探索新的教学模式，不断提高病理学教学质量。 Pathology is a discipline that uses natural science methods to study the etiology, pathogenesis, and structural and functional changes of cells, tissues, and organs and their evolution during disease, thereby elucidating the nature of the disease. It is not only a basic subject, but also a highly practical subject with clinical characteristics. It has long been a "bridge" course between basic medicine and clinical medicine, providing a theoretical basis for understanding and preventing and treating diseases. Pathology provides an important basis for clinical diagnosis of diseases through autopsy and biopsy. Pathological diagnosis is considered to be a definitive and authoritative diagnosis, so William Osler, a well-known American doctor and medical history expert said Physiology is the foundation of medicine ", and pathologists are considered" doctors' doctors. " The course content of pathology is divided into two parts: general theory of pathology (also called general pathology) and monograph of pathology (also called systemic pathology). The research and elaboration of the general theory are the basic pathological changes of cell and tissue adaptation and injury, injury repair, local blood circulation disorders, inflammation and tumor, which are the common laws of the occurrence and development of various diseases. On the basis of general studies, monographs study and elaborate the special laws of various diseases.Pathology courses include theoretical and experimental courses. The two are interconnected to deepen the understanding and mastery of pathological theoretical knowledge and strengthen the cultivation of knowledge utilization capabilities. "Pathology is the foundation of medicine" (William Osler). We firmly believe that good clinicians must have a solid knowledge of pathology. Facing the future, we strive to explore new teaching modes and continuously improve the quality of pathology teaching.
