Female triad is the general name of female thyroid nodule, hyperplasia of mammary gland and hysteromyoma.Professor TONG Xiaolin first proposed this concept because he found that clinically women always suffer from these three diseases at the same time or in succession.Thyroid nodule, hyperplasia of mammary glands and uterine leiomyoma often occur successively or jointly.Therefore, the concept of "female triad" is first put forward, and it is believed that the three diseases are inextricably linked in terms of pathogenic factors and pathogenesis.Western medicine holds that the thyroid, breast and uterus are regulated by the hypothalamus and pituitary gland.Diseases of the three parts are due to endocrine disorders.Therefore, the treatment is to start with the regulation of endocrine hormones and surgical treatment afterward.Chinese medicine believes that the etiology, pathogenesis and pathogenesis of the three diseases are similar, so the three diseases can be treated in the same way.Seven emotions disorder is the main cause of illness.Qi stagnation is the main pathogenic factor, while phlegm coagulation, Qi stagnation and blood stasis are the common pathological products.According to the clinical symptoms of "triad sign" , Professor TONG Xiaolin divided the diseases into stagnation and deficiency according to the difference of deficiency and excess.He puts forward the treatment method of "relieving stagnation and tonifying the deficiency" .The treatment is based on the principle of removing phlegm, dispersing and clearing collaterals.It is a unique way to apply target medicine to treat diseases and guide clinical practice.
