Objective: To analyze the distribution characteristics of hirsutism and the law of meridian differentiation in polycystic ovarian syndrome (PCOS).
Methods: For the patients of PCOS, the modified Ferriman-Gallwey score (mF-G score) was adopted to evaluate the hirsutism distribution. The clementine data mining software was used to analyze the distribution region of hirsutism and the correlation with meridian.
Results: A total of 141 patients of PCOS participated in the study. The most common regions of hirsutism were in the upper lip (50.35%) and the lower abdomen (34.04%). The higher frequencies of hirsutism at two regions were at the upper lip and lower abdomen (24.82%), the upper lip and chest (12.06%) and the upper lip and thigh (11.35%). In the analysis on the correlation of the upper lip, lower abdomen and chest with other regions, hirsutism was more common in the nearby regions. In reference to the running course of meridian, the frequencies of hirsutism from high to low were the conception vessel (63.12%), the thoroughfare vessel (61.70%), the liver meridian of foot-jueyin (58.16%) and the stomach meridian of foot-yangming (57.45%). According to Miraculous Pivot: Yinyang Twenty-Five Persons, the high incidence of hirsutism (59.57%） resulted from the change of qi and blood in yangming meridian. .
Conclusion: Blood plays the important role in the growth of body hair. Regarding the yinyang attribution, the incidence of hirsutism at the yin regions is higher than the yang regions. The occurrence of hirsutism is closely related to qi and blood changes in meridians. The conception vessel, the thoroughfare vessel, the liver meridian of foot-jueyin and yangming meridian act highly on the disease.
