Although human being do not clear the underlying mechanism of human common diseases such as cardiovascular disease, diabetes and osteoporosis, we try to model these disease based on the current physiology or pathophysiology knowledge by using quantitative methods. How to efficiently model human common diseases by using mathematical models, which can be used to prevention, diagnosis, treatment and prognosis of human common diseases if we create mathematical models of diseases successfully. Mathematical models in diseases is the foundation of precision medicine. This is because mathematics is the only science to handle precision questions or problems...
