Objective To explore the effect of Xiaoyao pill combined with low-dose corticosteroid on serum estrogens levels in the treatment of patients with menopause syndrome and its clinical efficacy.Methods 96 patients with menopause syndrome from April 2013 to February 2015 in department of obstetrics and gynecology of Lishui second people’s hospital were selected and divided into 2 groups according to a random number table, the control group (48 cases) were treated with small dose of hormone therapy, the treatment group (48 cases) were treated with Xiaoyao pill combined with small dose of hormone therapy.The serum estrogens levels, Kupperman score, endometrial thickness and clinical efficacy were compared. Results The total effective rate of control group(79.17%) was lower than that of treatment group(93.75%)(P<0.05).Compared with control group post-treatment, the serum follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were lower, estradiol (E2) level was higher, the Kupperman score was lower, the endometrial thickness was higher than those of control group, there were significant differences ( P <0.05 ) . Conclusion Xiaoyao pill combined with small dose of hormone could improve serum E2, FSH and LH levels in the treatment of patients with menopause syndrome with high security.

Objective:To establish an ultra performance liquid chromatography-tandem quadruple mass spectrometry ( UPLC-MS/MS) method to determine CYP2C9 activity in vitro. Methods:An ACQUITY UPLC? BEH C18 (100 mm × 2. 1 mm, 1. 7 μm) column was used as the stationary phase at 30℃. The mobile phase consisted of acetonitrile-water ( containing 0. 1% formic acid and 0. 5%ammonia water) (40∶60, v/v). The flow rate was 0. 2 ml·min-1. Chlorpropamide was used as the internal standard. The MS condi-tions were as follows:ESI with positive ion detection mode. Self-prepared CYP2C9?1, ?2, ?3 and ?13 protein were incubated with tolbutamide at 37℃ and 800μl ethyl acetate was added to stop the reaction. After centrifuged at 10 000g, the organic layer was then dried using nitrogen, the residue was re-dissolved in 200μl mobile phase and determined by UPLC-MS/MS. Results: The reten-tion time of 4-hydroxytolbutamide was 1. 21 min. An excellent linear calibration curve of 4-hydroxytolbutamide was obtained within the concentration range of 0. 05-5 ng·μl-1(r=0. 999 8). The lower limit of quantification of 4-hydroxytolbutamide was 0. 01 ng·μl-1 with the average recovery of 99. 3%-100. 3%. The intra- and inter-day RSDs were all less than 5%. There was no interference from the endogenous substances existing in the incubation system. The catalytic activity of the variants CYP2C9?2,?3 and?13 after tol-butamide was incubated with CYP2C9?1,?2,?3 and?13 was 47. 3%, 11% and 0. 3% of wild type CYP2C9?1. Conclusion:The method is simple and stable, and suitable for the fast evaluation of cytochrome CYP2C9 activity in vitro and relevant studies on the inhibitors.
