Objective: Preliminary studies have confirmed that Bushen treatment and Shugan treatment can improved the clinical pregnancy rate, pregnancy outcomes and oocyte quality in patients with IVF-ET(in vitro fertilization-embryo transfer, IVF-ET). This study continued to compare the Bushen with Shugan methods in vitro culture IVF-ET patients ACTA in ovarian granulosa cells and its role in regulating signaling pathways, to explore the similarities and differences in mechanism and detail pathways between the two methods.Methods:1 Preparation of serum containing drugs The serum contained Bushentiaojing recipe and Xiaoyaosan recipe: Female volunteers 10 were chosen at the age of 20-30 years old, in good health, with menstrual regularity, mature follicles showed by B-ultrosound, without organic diseases of, ovaries and uterus respectively, taking the Bushentiaojing recipe and Xiaoyasan recipe orally. Females took 300 ml of Bushentiaojing and Xiaoyaosan recipe each respectively day, in the morning and evening for 3 days. In the fourth day early in the morning on an empty stomach-a day,s dose of the drug(medication before fasting 12h), 1h after the last medication venous blood 5ml, for 2h at room temperature, 10 min for 3000 r per min, supernatant, 56 ℃ water bath for 30 min to inactivate complement, 0.22μm sterile filter filter-sterilized, aliquot preparation Bushentiaojing party Xiaoyaosan serum containing two kinds of people. Normal serum: Five female volunteers were selected, at the age of 20-30 years old, in good health, with menstrual regularity, with mature follicles by B-ultrosound, and without ovarian and uterine organic disease, fasting venous blood 5ml, above normal preparation serum, normal serum control set. Serum were saved at- 20℃ for later using. 2 The culture of granule cells in vitro Put the granulosa cells after centrifugation in 35 mm dish set 2ml nutrient solution, 37 ℃, 5% CO2(V/V), 100% humidity. Change the solution 24 h after the cells attached to the bottom of the dish and put Bushentiaojing Recipe and Xiaoyao san recipe serum. The follicles were divided into 8 groups according to the serum and doses level, named Bushen low,medium and high dose groups,Shugan low, medium and high dose groups, normal group and blank control group. Cultured after 24 h, granulosa cells were collected. The first batch of granulosa cells were collected by mechanical methods, stored at-80℃(for real-time fluorescent quantitative PCR). Using mechanical and enzymatic methods to collect the second batch, and fixed quickly by 2% paraformaldehyde(each for immunohistochemistry and immunofluorescence). Bushen high dose group and Shugan high dose group after 24 h incubation, adding SB431542(concentration of 10μmol/L), incubated for 2h, respectively, Bushen and Shugan Inhibitor group, collection and experimental methods were got as above.
