Qian Yi "sought medical advice from Lv Jun" at an early age. He is diligent and studious, and has studied Neijing, Treatise on Febrile Diseases, Shennong Herbal Classic and so on. Especially in Shennong's Classic of Materia Medica, he made great efforts to "correct mistakes". When someone asks him with different medicines, he always gives a detailed answer to the difference between "birth background" and "looking for a name and appearance". I checked this cursive script, and it is "all together". In addition, he also collected and studied all the information about pediatrics in ancient and modern times. Before Qian Yi, there was not much information about the treatment of pediatric diseases. According to Records of the Historian, Bian Que was a pediatrician, and Wei Xun in the Eastern Han Dynasty wrote The Cranial Classics, but it has been lost. There are also records about pediatric diseases in Chao's Theory of Etiology and Sun Simiao's Qian Jin Fang. In the early Song Dynasty, Wu, an ancient famous teacher, was asked to write two volumes of Cranial Classics, which talked about the pulse diagnosis of children, the diagnosis of diseases and the treatment of epilepsy, malnutrition, fire elixir (erysipelas) and miscellaneous diseases. Qian Yi repeatedly studied this book, which was deeply inspired and applied to clinical practice, and achieved good results. On the basis of syndrome differentiation and treatment summarized by Zhang Zhongjing, Qian Yi also explored a set of "five zang-organs syndrome differentiation" methods suitable for children with the help of the enlightenment of "children's pure yang" in the cranial meridian and his own clinical practice. Therefore, Yan Jizhong told him that "treating children should include ancient and modern times, but also be complacent."
Second, advocate maintenance.
Qian Yi's "keeping in good health" method has been proved to be a scientific and effective one by later generations. Qian Yi once said: "If you want your child to be safe, you often need to be hungry and cold." In other words, the child's internal organs are delicate and the digestion and absorption function is not perfect. If they are seven points full, their internal organs are not easily damaged. Children don't want to eat, and they don't have to chase after them. When children are hungry, they naturally have the will to eat. The child's Yuanyang is naturally active. Clothes that are too warm are easy to sweat and catch cold, leading to colds and colds. Therefore, children are kept in a "seven-minute temperature" environment, and it is not easy to cough and asthma.
The above methods are also applicable to adults. Qian Yi advocates eating too much and wearing too much, that is, eating too much and wearing too warm clothes. Exquisite things or favorite foods should not be eaten too much, because partial eclipse makes people lack the intake of various nutrients and makes people thin. At the same time, eating too much will cause patients or obesity.
Third, through facial diagnosis.
Ancient doctors called pediatrics dumb and thought pediatrics was the most difficult disease for children to treat. Because children can't talk, even children who can talk often can't express their ideas. Through more than forty years' medical practice, Qian Yi summarized the physiological characteristics of children and gradually explored a set of diagnosis and treatment methods. Qian Yi realized in practice that children's physiological characteristics are "weakness of viscera" and "insufficiency of five internal organs, both of which are not strong". Its pathological characteristics are: "easy to be deficient, easy to be born, easy to be cold and easy to be hot". Therefore, in order to overcome this difficulty, we must have a correct and comprehensive understanding of children's physiology and pathology.
In diagnosis, he advocated examining children's five zang-organs diseases from the aspects of face and eyes, and added two special observation methods of "exterior syndrome" and "internal syndrome". For example, he thinks that the left cheek is the liver, the right cheek is the lung, the forehead is the heart, the nose is the spleen, and the chin is the kidney. From the color changes of these parts, the child's condition can be judged. And observe the "redness" in the eyes, and the heart is hot. Pale red, hot. Young man, angry. Yellow, spleen heat. Without light, kidney deficiency. "In terms of prescription medication, we should refrain from attacking, making mistakes, and supplementing, and advocate the principle of' softness'.
