Premature ovarian insufficiency(POI)refers to a condition in women where ovarian function declines prematurely before the age of 40,leading to disruptions in the menstrual cycle and impaired fertility.Professor He Chengyao,based on the theory of yin and yang,formulates the theory of nourishing essence and fostering ovarian function,and accordingly invented a distinctive gynecological formula for menstrual regulation.This formula is designed to modulate the menstrual cycle and augment the pregnancy rate.Professor He is adept at treating female reproductive system disorders from the perspective of fundamental physiology and also attaches significant importance to syndrome differentiation of the internal organs.Based on Professor He's clinical syndrome differentiation and treatment methodology,this article explored the pathogenic mechanism of premature ovarian insufficiency and accomplished flexible syndrome differentiation and treatment for this disorder.

OBJECTIVE: To evaluate the therapeutic effects of Chinese materia medica in treating patients with different syndromes by tongue image analysis software 1.0 based on tongue colors, and to discuss the feasibility of applying this computer science-based techniques into drug evaluation. METHODS: The tongue colors and the areas of tongue fur were examined and analyzed by the tongue image analysis software 1.0 in healthy persons and the patients with different syndromes before and after treatment. The parameters of tongue colors consisted of the followings: the hue (H), the lightness (L), the saturation (S), and the values of red (R), green (G) and blue (B). RESULTS: Obvious differences could be revealed in tongue color index between the healthy persons and the patients in five groups of different syndromes. There also existed some significant differences in those index between patients before and after treatment. CONCLUSION: The tongue image analysis software 1.0 based on tongue colors is helpful to evaluate the therapeutic effects of Chinese materia medica.
