摘　　要：Background:Polycystic ovary syndrome(PCOS)is an endocrine disorder that occurs in women of child-bearing age.Moreover,PCOS patients have decreased pregnancy rates and clomiphene citrate resistance.The traditional Chinese medicine formula Kun-Tai-1S(KT1S),consisting of the seahorse species hippocampus,has been reported to elicit therapeutic effects in patients with PCOS.However,given the limited resources and global demand for wild hippocampus,whether KT1S with or without hippocampus can elicit similar therapeutic effects has not been confirmed.Methods:KT1S and Kun-Tai-1A(KT1A,KT1S without dry hippocampus)were used to treat a letrozole-induced rat model of PCOS with an established disease.The serum levels of testosterone,luteinizing hormone,anti-Müllerian hormone,and estradiol were determined,the luteinizing hormone/follicle-stimulating hormone ratio was determined,and the ovarian pathology was evaluated.Results:Similar to the therapeutic effects of cyproterone acetate,both the KT1S and KT1A treatments reduced the body weight and ovarian and uterine indices in the rats with PCOS.The serum levels of testosterone,anti-Müllerian hormone,and luteinizing hormone and the luteinizing hormone/follicle-stimulating hormone ratio were significantly lower in the KT1S and KT1A treatment groups compared to the model group(P<0.01 and P<0.05,respectively).Moreover,the histopathological assessment results suggested that both the KT1S and KT1A treatments significantly ameliorated the PCOS pathology in the rats with an established disease,with a reduced number of cystic and atretic follicles and an increased number of corpora lutea being observed in the ovaries.Notably,there was no obvious difference in the disease outcomes between the KT1S and KT1A-treated groups.Network pharmacology analysis revealed that 4’,7-dihydroxyflavanone,sinpemine A,quercetin,8-isopentenyl-kaempferol,and luteolin in KT1A may promote estrogen signaling;furthermore,the nitric oxide regulation pathway is also closely involved.Conclusion:KT1A and KT1S trea
