临床科研是在临床医学领域里探索未知的过程。其基本要素是“实践与结合实践的理论思维”。糖尿病和汞剂利尿药的发现,就是医护人员在临床实践中注意到病人某一特殊征象,追究其原因而取得的研究成果。这些事实说明了“实践与理论”,“临床与科研”的关系是相辅相成的,不可分割的。一个好的科研课题必须有合理的科研设计。所获资料必须严密、精确、可靠。据报道十几年来国内治疗冠心病的药物达六、七十种,几乎每篇报道都说疗效达70％或80％以上,但大多数未提出可令人信服的资料,即所用方法不科学,如分组不随机,缺乏对照 Clinical research is exploring unknown processes in the field of clinical medicine. The basic element is “practical and practical theoretical thinking.” The discovery of diabetes and amalgam diuretics is a result of research that has been made by medical personnel in clinical practice to take note of a patient’s specific signs and pursue the causes. These facts demonstrate that the relationship between “practice and theory” and “clinical and scientific research” are complementary and inseparable. A good scientific research project must have a reasonable research design. The information obtained must be rigorous, accurate, and reliable. According to reports, there are six to seventy kinds of drugs used to treat coronary heart disease in China for more than ten years, and almost every report says that the efficacy is 70% or more, but most of them have not provided convincing data, that is, the methods used are not scientific. , such as grouping is not random, lack of control
