The Outline of Pathology for International Students (Minimal Requirements) February 2014 1 四川大学全英语授课专业课程大纲 Syllabus of English-Teaching Program at SCU Course Code: 50200960 Total Class Hours: 108 Course Name: Pathology IV Credit: 6 Textbook/Teaching Material: Robbins Basic Pathology. 9th edition, Kumar V, Abbas AK, Fausto N, Mitchel R, eds, 2007, Elsevier Sauders Course Objective: Pathology is a scientific study of disease. It is a bridging discipline involving both basic science and clinical practice and is devoted to the study of the structural and functional changes in cells, tissues, and organs that underlie diseases. By the use of molecular, microbiologic, immunologic, and morphologic techniques, pathology attempts to explain the pathogenesis, etiology, signs and symptoms manifested by patients while providing a sound foundation for rational clinical care and therapy. Pathology is also one of the most important methods to diagnose disease in clinical practice. By studying pathology, the medical students should not only understand the basic pathologic knowledge and master the skills, but also prepare themselves for bigger clinical courses ahead. Traditionally, the study of pathology is divided into general pathology and systemic, pathology. The former is concerned with the basic reactions of cells and tissues to abnormal stimuli that underlie all diseases. The latter examines the specific responses of specialized organs and tissues to more or less well-defined stimuli. The teaching contents include lectures, laboratory practice, autopsy demonstration and clinicopathologic conference (CPC). For medical students, the goal of learning pathology is able to analyze the relationship between pathologic changes and clinical manifestations and to understand a pathologic diagnosis correctly.
