Qian Yi is the first famous pediatrician in the medical history of China, and the first extant pediatric monograph in China. This paper systematically summarizes the methods of syndrome differentiation and treatment for children for the first time, which makes pediatrics develop into an independent discipline. Later generations regarded it as a classic of pediatrics, and called it Qian Yi, the sage of pediatrics, the founder of a young family. Qian Yi, the word Zhongyang. His ancestral home was Qiantang, Zhejiang, and his grandfather moved north, so he was born in Yunzhou, Dongping. Born in Song and Yuan Dynasties, he died in Zheng He for three years. Qian Yi's life, the most prominent academic place, is devoted to industry. He has been dead for forty years. Practitioners all know that ancient doctors called pediatrics dumb and thought it was the most difficult pediatric disease to treat. Because the child's pulse is a little unclear, he cried badly during the examination, and it is difficult to distinguish symptoms through pulse diagnosis. This is one; The child's spine is immature, his shape and voice are not correct, he cries sadly, laughs happily and is abnormal, and it is difficult to understand his illness when he sees a doctor. This is the second; Children don't have to be able to talk, and talking without practice is not enough to win trust. It is more difficult to understand the illness by asking questions. This is three; Children's viscera are weak, easy to be deficient and easy to be solid, easy to be cold and easy to be hot, and a little improper medication is enough to complicate the condition. This is four. Therefore, in the process of practicing medicine, Qian Yi also deeply felt that pediatric diseases were difficult to treat. It is difficult to get information about the pulse, but the evidence cannot be confused by words, he said. This is especially true for babies or children. It took him nearly forty years to overcome this difficulty. Word: good things are much ground. Sure enough, his success laid a solid foundation for the development of pediatric medicine in China. Qian Yi asked the doctor in Lv Jun since he was a child; Diligent and studious, seriously study Neijing, Treatise on Febrile Diseases, Shennong Herbal Classic, etc. Especially Shennong's Herbal Classic, he clearly distinguishes right from wrong and has profound skill. Someone asked him with different medicines, and he always asked; At the end of the birth, find out the name differences and answer them in detail. I checked a cursive script, and it's all there. In addition, he also collected and studied ancient and modern pediatric materials one by one. Before Qian Yi, there was not much information about children's treatment of diseases. According to historical records, Bian Que used to be a pediatrician, and Wei Xun wrote Cranial Classics in the Eastern Han Dynasty. Unfortunately, it has been lost. Sun Simiao's Thousand Golden Prescriptions also recorded pediatric diseases. Wu Zhu, an ancient teacher in the early Song Dynasty, has two volumes: Pulse Diagnosis in Children, Diagnosis of Disease Syndrome and Treatment of Asthma, Dysentery, Fire Pills and Miscellaneous Diseases. Repeated study of Qian Yi's book is very enlightening, and it has been used in clinic, and it has received curative effect. Qian Yi also relies on cranial meridians; Children's pure yang summed up Zhang Zhongjing's syndrome differentiation and treatment, and explored a set suitable for children. Syndrome differentiation of five internal organs; Law. Therefore, Yan Jizhong should be complacent about his way of treating children in ancient and modern times. When studying in Qian Yi, it is not the teacher who is good at saying goodbye to the old and welcoming the new. For example, his Liuwei Dihuang Pill. It consists of Radix Rehmanniae Preparata, Rhizoma Dioscoreae, Fructus Corni, Poria, Alismatis Rhizoma and Cortex Moutan. It turned out to be Zhang Zhongjing's synopsis of the golden chamber, which is to improve Bawei Shenqi pill and make Liuwei Dihuang pill as a tonic for teenagers. This has played a certain role in enlightening people who advocate nourishing yin in later generations. For example, Qiwan Dabuyin Pill, one of the four famous doctors in Li Dongyuan Jin and Yuan Dynasties. This is carbon monoxide

Therefore, to overcome the difficulties of pediatric diseases, we must have a correct and comprehensive understanding of children's physiology and pathology. On the basis of years of clinical practice, he gradually explored a set of diagnosis and treatment methods. In diagnosis, he advocated examining children's five internal organs from face and eyes, such as left cheek liver fever, right cheek lung, kidney deficiency and blindness. In the aspect of prescription medication, we should strictly refrain from rash advance, false supplement and strict supplement, and advocate the principle of operation. A man named Zhu has a five-year-old son. He has a fever at night and has nothing to do during the day. Some doctors treat typhoid fever, others treat fever, and use cold medicine to relieve his exterior syndrome, but they can't be cured. Symptoms of illness are: salivation and drowsiness. Other doctors used iron powder pills to swallow saliva, but their condition worsened. On the fifth day, they were thirsty and drank. Qian Yi said: You can't use the rule of law. So he took a drop or two of Atractylodes macrocephala powder and boiled three liters of water for the sick children to drink during the day. Zhu asked: Don't you have diarrhea after drinking too much? Qian Yi replied: Only when raw water seeps in, will you have diarrhea. Even diarrhea is not surprising, but you can't use the rule of law; People surnamed Zhu asked again: What disease should be treated first? Qian Yi said: This medicine is used to quench thirst, resolve phlegm, reduce fever and clear heart. In the evening, it is estimated that when taking medicine, Qian Yi saw the sick child and said, you should drink three liters again. After taking three liters of Baizhu powder, the sick child felt a little better. On the third day, he drank three liters of Bai Shu Sanshui, and the sick child was no longer thirsty or drooling. Then Qian Yi gave him two doses of gelatin powder, which was made of donkey-hide gelatin, burdock, licorice, Aristolochia, almond and glutinous rice, and his illness was completely cured. After 40 years of in-depth research in pediatrics, Qian Yi finally found out the rules of diagnosis and treatment of pediatric diseases and accumulated rich clinical experience. He wrote five volumes of Treatise on Febrile Diseases and hundreds of books about infants, all of which were lost. The existing direct formula of pediatric medical syndromes, or Hou Zhen Fang of pediatric medical syndromes, was compiled by his student Yan Jizhong in119. This book has three volumes, the first volume is evidence, the second volume is case handling, and the second volume is parties. The book records the identification method of measles and the treatment method of whooping cough for the first time; It is also the first to identify smallpox, measles and chickenpox from the characteristics of rash; Describe various neonatal diseases and developmental nutritional disorders in children, as well as various famous and effective prescriptions; It also created the earliest pediatric medical record in China. First, this book has been valued by Chinese medicine practitioners in past dynasties and listed as a must-read bibliography for learning pediatrics. It is not only the first systematic and complete pediatric monograph in China, but also the earliest pediatric monograph in the world. Shu, the originator of the Yang family introduced by later generations, often has the function of rejuvenation; In short, his achievements are positive. He has made great contributions to the formation and development of pediatrics and is an outstanding pediatrician. Qian Yi was born in Dongping in Song Dynasty. He was born between Renzong and Hui Zong in the Northern Song Dynasty. He died in 82. He was a famous pediatrician in Song Dynasty. Qian Xuesen, formerly known as the Catalogue Summary of Sikuquanshu, is a pediatrician. He has cured the pediatric diseases of the royal family and the national health, and has a prominent reputation. He was awarded the Doctor of Medicine of Hanlin. He used to be a doctor in a Thai hospital. During many years of medical practice, Qian Yi accumulated rich clinical experience and became a famous physician at that time. This young family named Qian Yi is the first generation. It's no exaggeration. He wrote many books in his life, including five volumes of Cranial Prescription, one hundred volumes of Sikuquanshu, eight volumes of Treatise on Febrile Diseases and three volumes of Infants. There are only prescriptions for Qian's children, and everything else is available.

It is believed that pediatric diseases should not be misused unless they can be used according to their age, physique, good and evil. In addition, Qian Yi applied the five zang-organs syndrome differentiation method to children on the basis of children's medical syndrome, medicine syndrome, Neijing and Jingui, and put forward the syndrome differentiation method for children's clinical treatment. He believes that the main symptoms are shock, liver controlling wind, spleen depression, asthma and kidney deficiency. Among them, Qian attached great importance to the syndrome differentiation of cold-heat deficiency and excess of viscera, and put forward a series of corresponding treatment methods for different diseases. It can be said to be a systematic system of syndrome differentiation of viscera. Although it is not very comprehensive, it has a preliminary framework, which has contributed to the formation of the theory of syndrome differentiation of viscera in traditional Chinese medicine. Qian Yi emphasized syndrome differentiation of the five zang-organs, and his prescriptions and adjustments were mostly based on the deficiency and excess of the five zang-organs, such as Daochi powder for heart excess heat and Shengxi powder for heart deficiency heat. Xiexin pill is used for liver excess heat syndrome, and Liuwei pill is used for liver deficiency heat syndrome; Yihuang powder for spleen deficiency and Xiehuang powder for spleen dampness and heat; Colla Corii Asini powder is used for lung deficiency and Allium macrostemon powder for lung heat; Kidney deficiency is treated with Liuwei Dihuang Pill. Prescription principle emphasizes soft selection of drugs and opposes excessive use of offensive products. His medication principle is based on the characteristics of children. In addition, when dispensing medicine, Qian Yi flexibly adds and subtracts new prescriptions according to his past experience and his own experience. For example, Dihuang Pill, which he founded, was made from Shenqi Pill by cutting and sticking it in Guangxi. In addition, according to the characteristics of pediatrics, money is often used in the form of pills, powders and ointments in clinical medicine. These finished drugs can be prepared in advance, adapt to the characteristics of acute onset and rapid change of pediatric diseases, facilitate timely administration, and are easily accepted by children. Qian Yi's achievements in pediatrics were praised by later generations, which had a great influence on TCM syndrome differentiation and treatment and prescription science. But limited by the medical level at that time, it is impossible to be perfect. For example, he founded Liuwei Pill to tonify the kidney, focusing only on the aspect of kidney yin deficiency and ignoring the aspect of kidney yang deficiency. Because of this, later generations gradually developed and improved. This also reflects the historical position of Qian Yi in the history of TCM development.
