Abstract: Daytime frequent urination syndrome is one of the common diseases in children，which is characterized by a significant increase in the requency of urination during the day，without fever，pain or other discomfort.Modern medicine believes that the occurrence of the disease may be related to the immature development of the central nervous system in children.Mental tension is an important inducing factor.The main treatment is to alleviate the frequency of urination，and cholinergic receptor antagonists are often used.Relapse often occurs after drug withdrawal and there are many side effects.In addition，daytime frequent urination syndrome is often misdiagnosed as urinary tract infection，resulting in the abuse of antibiotics.Traditional Chinese medicine is effective in the treatment of the disease.Huang Yuanyu was one of the famous doctors in Qing dynasty，whose main academic thought is "circulation of one qi".The theory emphasizes that the rise and fall of middle qi is in the core position of the human body，and in physiology，spleen ascending and stomach falling results in wood fire rising and floating，gold water converging and falling，water and fire intersecting and yin and yang harmonizing;pathologically，if qi is in disorder，diseases will arise.Based on this theory，the incidence of daytime frequent urination syndrome is related to earth deficiency，wood depression and water coldness.The movement of body fluid is weak due to the deficiency of middle earth;the body fluid doesn′t circulate actively because of wood depression in the left side;the body fluid can′t be transformed due to water coldness in the right side;the deficiency and decline of middle yang is the main pathogenesis.Therefore，the principles of treatment are to warm middle earth，regulate liver，and warm Kidney to recover the circulation of one qi so that the body fluid moves in harmony and frequent urination is cured.
