In the course of our doctors’ life practice, we have to use hormones more or less to treat patients with cranio-cerebral injuries, various toxic reactions, anti-allergy, serious infections, antipyretic treatment of fever, treatment of rheumatism, treatment of nephritis, and so on. The application of hormones may produce osteoporosis, femoral head necrosis, diabetes, infections, and centripetal obesity, which makes the people talk about hormones and reject them very much. In fact, if applied properly, hormone is a good medicine. We clinicians carefully grasp the application indications, do a good job in the prevention and treatment of side effects, and do a good job in patient education and guidance, and hormones successfully cooperate with us to save patients. Reasonable application, attention to prevention and regular follow-up.
