OBJECTIVETo study the phytoestrogenic effects and their possible mechanisms of Jiaoai tang and Shenqi Jiaoai tang through the tests in mice and ER (+) MCF7 cells.
METHODSixty kunming mice weighing 9-12 g were randomly divided into 6 groups: solvent control group (administrated equal dose of diswater), diethylstilbestrol control group (administrated diethylstilbestrol at a dose of 0.35 mg x kg(-1) x d(-1) and 4 Chinese medicine treated groups (administrated low or high doses of Jiaoai tang and Shenqi Jiaoai tang at 2.5 g x kg(-1) x d(-1) or 5.0 g x kg(-1) x d(-1) respectively). After administration for 4 days, the mice were sacrificed; uterus was removed and weighed, uterus rate was calculated. The blood serum was also separated. The proliferation rate of MCF7 cells influenced by Jiaoai tang and Shenqi Jiaoai tang was determined by MIT assay. PS2, ERalpha and ERbeta mRNA expression was quantified by Real-time PCR assay. Estrogen receptor antagonist ICI182, 780 was employed as a tool.
RESULTAdministration of Jiaoai tang and Shenqi Jiaoai tang at high dose significantly increased uterus rate in mice (P < 0. 05). The pharmacological serum from two high-dosage groups of Chinese herbal medicine decoction significantly enhanced proliferation rate of MCF7 cells (P < 0.05 or 0.01), while their effects were blocked by ICI182, 780 (P < 0.05 or 0.01). The pharmacological serum could cause elevation of pS2 level (P < 0.01) which would be obviously inhibited by ICI182, 780 (P < 0.01). ERalpha and ERbeta mRNA levels were also elevated significantly (P < 0.05 and P < 0.01 respectively).
CONCLUSIONJiaoai tang and Shenqi Jiaoai tang have phytoestrogenic effects, which were attained via ER pathway. They can also increase the mRNA levels of estrogen receptor subtypes, especially ERbeta.

Postmenopausal osteoporosis is one of the commonest systemic bone metabolism diseases among menopausal women, mainly caused by lowering internal estrogen. Although Hormone Replacement Therapy (HRT) is an effective method in clinical practice for years, it shows side-effect in increasing gynecological carcinoma. It has already been proved by clinical tests that multiple traditional Chinese medicine formulas and their monomer ingredients and phytoestrogen-like active constituents contained in traditional Chinese medicines are effective on treating osteoporosis with relatively less side-effects comparing with HRT. They show protective and therapeutic effects by acting on estrogen receptors of targeted tissues and targeted cells and then affecting expressions of bone metabolism-related regulatory proteins and factors in downstream signal conduct paths. Recent studies on estrogen related receptor (ERR) provide new possibilities and pathways for mechanism of traditional Chinese medicine and their active constituents in osteoporosis.
