疾病的过程尽管有千差万别的形式,但本质上都是损害与抗损害的矛盾斗争;损害,虽然对人体不利,但也是人体在一定的条件下的不平衡运动。致病因素虽然是造成损害的重要条件,但损害终究是人体的自身运动变化。而抗损害是机体对损害因素作用的能力,包括人体的防御功能和代偿功能两个方面。 The disease process, despite the vastly different forms, is essentially a contradiction between the damage and the fight against damage. Damage, although unfavorable to the human body, is also an unbalanced movement of the human body under certain conditions. Although the pathogenic factors are important conditions that cause damage, but the damage is after all, the body’s own movement changes. The anti-damage is the body’s ability to damage the role of factors, including the body’s defensive function and compensatory function in two aspects.
