As Professor Lang Jinghe wrote in his “Revelation of Medical Practice”, even a young doctor is an elder in the eyes of his patient, who is willing to pour out everything to you; even a doctor who is incompetent is a sage in the eyes of his patient, who thinks you can solve everything. This is where the difficulty of doctors lies. In the face of the patient’s dependence and trust, the doctor’s sense of responsibility and accountability is particularly strong. The doctor is the only person the patient can confide in, or even confide in, in order to relieve him. Regardless of the doctor’s age, gender, experience, experience, or skill, the patient will tell the doctor all his feelings, pains, and problems. So, no matter how personal, embarrassing or even unbelievable the patient’s “story” is, the answer is hidden in the patient’s account. As a doctor, you should listen carefully and seriously, accept it, and give answers and help as much as possible. Young doctors, despite their limited experience, are full of energy, and by taking each patient seriously they are gaining experience for themselves. A young doctor cannot be rash and certainly cannot pretend to be old, but he or she must treat the seeker with an old-fashioned attitude. A young doctor is certainly not an elder, but if the patient sees you that way, you should be self-respecting and respectful. The patient comes to the doctor, of course, to relieve the pain, regardless of how good the doctor is, or whether it can be done as desired. When a doctor sees a patient, of course, he should make a clear diagnosis and solve the problem, whether he can do it or not, he should do his best. Due to the complexity of the disease itself and the limitations of the development of clinical medicine, there are many diseases that we do not know or do not know enough at present, and in addition, the condition and standard of each hospital and each doctor vary, so it is common to have unclear diagnosis and unsatisfactory treatment. However, patients and the public do not understand this, which in a way stimulates the conflict between doctors and patients. According to statistics, even in a comprehensive high-level hospital, only a little more than one-third of patients are completely cured; most of them have their disease under control, in remission, or have a clear diagnosis and find a way to maintain or consolidate their treatment in the future; there is a small percentage that is actually not cured. Whether doctors, patients, or the public, please pay attention to this “actually incurable” small part! Doctors pay attention to it because they want to overcome the difficulties and see it as the focus of research. Patients and the public pay attention to it because they want to understand the limitations of medicine and the helplessness of doctors, and cooperate with them to try to improve the outcome of treatment. Both doctors and the public should deeply understand that the origin of medicine is the respect for human life, the love for human body, and the care and kindness for human nature. This is the professional mission of doctors. For this small group of people, alleviating suffering and improving the quality of life is the mission of medicine, because we can’t completely eradicate the disease now. “We cannot guarantee to treat every patient, but we must guarantee to treat every patient well.”
