Metrorrhagia and metrostaxis are the most serious menstrual disorders in gynecology of Chinese medicine. XIA Guicheng constantly innovates on the basis of medical thoughts of ancient physicians

forming the theory of pathogenesis of metrorrhagia and metrostaxis with disharmony between heart and kidney as body

and involving the liver and spleen above the structure of "heart（brain）-kidney-uterus axis "and "major governance of the heart（brain） ". The treatment focuses on joint regulation of the heart and kidney

and forms the metrorrhagia and metrostaxis theory of "regulating cycles"and "regulating axis"

which is in line with the theory of "menstrual cycle rhythm".The system remains consistent in the treatment of metrorrhagia and metrostaxis in all ages

and its theory of metrorrhagia and metrostaxis is highly compatible with modern medical research.
