OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.

A new method for simultaneous determination of six benzoic acid esters and their metabolite p-hydroxybenzoic acid (p-HB) in sediments was developed.The samples were extracted with methanol and water,and then the extraction was purified by Oasis MCX solid phase column.The separation of targets was conducted by passing through a UPLC?HSS T3 column with a methanol-0.1% acid aqueous solution as the mobile phase under gradient elution.The qualitative analysis of the analytes was measured by Ultra performance liquid chromatography-Triple quadrupole tandem mass under multiple reaction monitoring mode (MRM) and the internal standard method was applied for quantitative analysis.The results indicated that seven target substances had a good linear relationship in the range of 0.1-500 μg/L with correlation coefficients above 0.9995 and the detection limits of 0.75-1.23 ng/g.The recoveries ranged from 65.5% to 88.3% and the relative standard deviation was 7.4%-13.6%.This method was suitable for the measurement of benzoic acid esters with the advantages such as simple processing,good selectivity and high sensitivity.

Objective To explore the relationship between gene polymorphism of neuropeptide Y (NPY) promoter and cerebral stroke subtypes according to TOAST (Trail of ORG 10172 in Acute Stroke Treatment) criteria in Chinese Han population. Methods The gene polymorphisms at position of-399T/C, -883Tgins/del and -602G/T in NPY promoter were detected by PCR method and gene sequencing in 190 cases of large-artery atherosclerosis stroke (LAA), 260 cases of small-artery occlusion (SAO), 60 cases of cardioembolism stroke (CE), 29 cases of stroke of other demonstrated etiology (ODE),10 cases of stroke of other undemonstrated etiology (UE) and 423 healthy control subjects. The PCR products were directly sequenced. Multivariate logistic regression was performed to analyze the relationship between gene polymorphism of NPY promoter and cerebral stroke subtypes according to TOAST by removing the confounding variables. Results Significant differences in the frequency of genotype CC and allele C at position of-399T/C were noted between the patients with SAO and controls (P=0.046, P=0.010). Compared with the control group, patients with LAA and SAO were more likely having high level of uric acid, hypertension, diabetes mellitus and heard disease (P＜0.05). No statistic differences in the frequency of genotype DD and allele D at position of-883Tgins/del were noted between patients with SAO and controls (P=0.0605, P=0.155). Gene polymorphisms of-399T/C,-883Tgins/del and -602G/T did not associate with an increased risk of having LAA, CE, ODE and UE.Conclusions The gene polymorphisms of promoter in position of-399T/C gene maybe associate with the happening of SAO; allele C at the position of-399T/C may raise the risk of the disease. There is no relationship between the gene polymorphisms of promoter at position of-399T/C, -883Tgins/del, -602G/T and the patients with LAA, CE, ODE and UE. High level of uric acid, hypertension, diabetes mellitus and heard disease history are the risk factors of LAA and SAO.

OBJECTIVETo explore the potential molecular mechanisms for Bushen Tiaojing Recipe (BTR) improving the endocrine function of ovarian granular cells by observing the effect of BTR containing serum on follicle stimulating hormone/cyclic adenosine monophosphate-protein kinase A (FSH/ cAMP-PKA) pathway in in vitro cultured human ovarian granular cells.

METHODSThe primary ovarian granular cells collected from in vitro fertilization-embryo transfer patients were cultured for 24 h. The human and rat serum containing different concentrations of BTR (low, medium, high dose), and their normal serums were co-incubated with ovarian granular cells for 48 h respectively, and then they were divided into the low, medium, high dose BTR groups and the control group. The levels of estradiol (E2), progesterone (P), and cyclic adenosine monophosphate (cAMP) in the culture medium were measured by radioimmunoassay. The protein expression of FSHR in ovarian granular cells was detected by Western Blot. The mRNA expression of follicle stimulating hormone receptor (FSHR) and P450 aromatase (P450arom) in ovarian granular cells were detected by Real-time PCR.

RESULTSIn human BTR containing serum groups: Compared with control group, the levels of E2 and cAMP in the culture medium were higher (both P < 0.05) in the medium and high dose BTR groups; the levels of P in the culture medium decreased in the medium dose BTR group (P < 0.01). The protein and mRNA expression of FSHR in ovarian granular cells increased (all P < 0.01), the mRNA expressions of P450arom in ovarian granular cells were higher (P < 0.05, P< 0.01) in the medium and high dose BTR groups. In rat BTR containing serum groups: Compared with the control group, the levels of E2 in the culture medium were higher (all P < 0.01), cAMP in the culture medium were higher (P < 0.05, P < 0.01) in the medium and high dose BTR group; the levels of P in the culture medium decreased in the medium dose BTR group (P < 0.01). The protein and mRNA expression of FSHR in ovarian granular cells were higher (all P < 0.01), the mRNA expression of P450arom in ovarian granular cells increased in the medium and high dose BTR groups (P < 0.05, P < 0.01).

CONCLUSIONBTR could possibly improve the endocrine function of ovarian granular cells by regulating main effector molecules FSHR, cAMP, P450arom, and E2 in FSH/cAMP-PKA pathway of ovarian granular cells.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the expressions of drosophila mothers against decapentaplegic protein (Smadl), Smad5, Smad8, and Smad4 on human mural granulosa cells.

METHODSSixty-six patients undergoing in vitro fertilization-embryo transfer (IVF-ET) were randomly assigned to two groups in the ratio of 1:2, the treatment group and the control group. Twenty-three patients in the treatment group were treated with BTR and GnRHa/FSH/hCG, while forty-three patients in the control group were treated with GnRHa/FSH/hCG. The mRNA expressions of Smad1, Smad5, Smad8, and Smad4 on mural granulosa cells of the mature follicle were detected by real-time PCR on the ovum retrieval day. The expressions of Smad1, Smad5, Smad8, and Smad4 at the protein level were observed using cell immunofluorescence method.

RESULTSThe mRNA and protein expressions of Smadl in the granulosa cells were significantly higher in the treatment group than in the control group (P <0.05). There was no statistical difference in the mRNA and protein expressions of Smad5, Smad8, and Smad4 between the two groups.

CONCLUSIONThe mechanisms of BTR for improving the pregnancy rate and the ovarian functions might be correlated with up-regulating mRNA and protein expressions of Smadl of human mural granulosa cells.
