The concept of"one qi peripheral flow"originates from the ancient Chinese philosophy of"qi monism"and the theory of yin and yang chi chemistry in the Yellow Emperor's Classic of Internal Medicine,and was formally proposed in Huang Yuanyu's The Origin of the Four Sacred Hearts,which elaborates on the theory of one qi circumference in which the earth pivots on four signs and the left rises and the right descends.Based on this theory,this paper discusses the diagnosis and treatment of thyroid nodules,believes that the development of thyroid nodules is closely related to the deficiency of the earth and qi,and the disorder of the liver and lungs,and combines the evidence of modern research to argue that the deficiency of the earth and qi,and the disorder of the liver and lungs are the important pathomechanisms of the thyroid nodules,proposes to refer to the results of ultrasound elasticity imaging of the thyroid gland for staging and typing treatment of thyroid nodules.It also summarizes the clinical use of medicines in different stages and types,aiming at estoring the"one qi peripheral flow"in the body,and provides a new diagnostic and therapeutic idea for the clinical diagnosis and treatment of thyroid nodules.
