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.

OBJECTIVEBone-marrow derived mesenchymal stem cells (BMSC) have the potential to differentiate into endothelial cells. The aim of the study was to investigate the induction process of BMSC by B16 melanoma cells in vitro and to analyze the role of VEGF-a in the process.

METHODSA co-culture system containing BMSC and B16 melanoma cells based on transwell indirect model was established, and the induction process of BMSC by B16 melanoma cells was studied in vitro.

RESULTSBMSC were isolated from the bone marrow of C57 mice. BMSC expressed CD105, CD90, CD73, CD44 and CD166, and acquired expressin of endothelial phenotype markers including VEGFR-1, VEGFR-2 and Factor VIII after co-culture with B16 melanoma cells for 48 hours. The expression level of VEGFR-2 would be double and Factor VIII threefold more by extending the co-culture time to 72 hours. In the co-culture system, B16 melanoma cells also up-regulated the expression of VEGF-a.

CONCLUSIONSVEGF-a plays a significant role in the differentiation of BMSC into cells of endothelial phenotype, therefore, is important to tumor angiogenesis.

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.

OBJECTIVETo investigate the effect of Inonotus obliquus polysaccharides on testicular injury induced by exposure to high power microwave (HPM) in rats.

METHODSA total of 30 male Wistar rats were randomly divided into 5 groups, i.e., the normal control group, the microwave radiation model group, the treatment group, the new microwave radiation model group, and the prevention group, 6 in each group. All rats, except those in the normal control group, were exposed to microwave at an average power density of 200 mW/cm2 for 6 min. Rats in the control group and the model group were administered with normal saline by gastrogavage, once a day. Rats in the treatment group and the prevention group were given with Inonotus obliquus polysaccharides by gastrogavage, 2 mL each time (400 mg/kg body weight), once a day. All rats were sacrificed on the 11th day.The sperm density and the rate of sperm deformity were determined. Pathological changes of testis were observed by light microscope and transmission electron microscope.

RESULTSShort-term HPM irradiation could significantly reduce the sperm density and increase the sperm deformity rate (P < 0.05). Meanwhile, obvious pathological changes of testes occurred. Compared with the two model groups, the sperm density increased and the sperm deformity rate decreased in the treatment group and the prevention group (P < 0.05). Under the light microscope, injuries of spermatogenic cells and stromal cells, as well as vascular dilatation and congestion were obviously alleviated in the treatment group and the prevention group. Mitochondrial swelling and endoplasmic reticulum expansion shown by ultrastructural observation were also significantly alleviated. Of them, injuries of spermatogenic cells and inflammation response were milder in the treatment group than in the prevention group.

CONCLUSIONSInonotus obliquus polysaccharides had significant protective effect on microwave radiation induced testicular injury. Better effect was obtained by therapeutic medication than preventive medication.

Objective To investigate the change of the basic fibroblast growth factor(bFGF) leve in human detrusor muscle(DM)in bladder outlet obstruction(BOO)due to benign prostatic hyperplasia(BPH)and its implication.Methods Fifty-four patients with BPH were divided into two groups:the obstructive DM stability and instability groups;and 15 men with bladder tumor who underwent operation in the same period were enrolled in the control group.The bFGF mRNA level in DM was measured by reverse transcription and polymerase chain reaction(RT-PCR)and the bFGF protein level was measured by immunohistochemical staining method.Results The bFGF-mRNA expression level of bladder smooth muscle cells was significantly lower in the control group than that in the obstructive DM stability and instability groups(all P＜0.05),but there was no significant difference between the obstructive DM stability and instability groups(P＞0.05). Conclusions The expression level of bFGF mRNA in bladder DM is elevated in BOO due to BPH,but there is little or no correlation between the increased expression of bFGF mRNA and detrusor muscle instability.

OBJECTIVETo explore the existence of vasculogenic mimicry (VM) in ovarian carcinoma and its correlationship with the clinicopathologic features and prognosis of the tumor.

METHODSA total of 84 ovarian carcinoma cases were collected with complete clinical and prognostic data. CD31 immunohistochemistry and PAS special stain were used to investigate VM in the tumor tissue. Immunohistochemical staining of VEGF, MMP-2, MMP-9, E-cadherin, beta-catenin, and Vimentin were used to explore the pathogenesis of VM.

RESULTSTotally 36 of 84 cases exhibited evidence of VM. FIGO classification, pathologic grades and histological types were significantly different between the VM and non-VM groups. Expression of VEGF, MMP-2, MMP-9, E-cadherin and beta-catenin were higher in the VM group than in the non-VM group. Kaplan-Meier survival curve analysis showed that cases of the VM group had a lower survival rate than that of the non-VM group (P = 0.04).

CONCLUSIONSVasculogenic mimicry exists in ovarian carcinoma. Ovarian carcinomas with a high grade malignancy have a high incidence of VM formation, a higher incidence of metastases and a lower survival rate. High expression of MMP-2 and MMP-9 may contribute to the formation of VM in the ovarian cancer.

To study the preparation, activity and targeting ability evaluation in vitro on epigallocatechin-3-gallate (EGCG) bovine serum albumin nanoparticles targeting to PC-3 cells, the folate mediated EGCG bovine serum albumin nanoparticles (FA-EGCG-BSANP) were prepared by desolvation process. The morphology and particle size of the nanoparticles were determined by atomic force microscope (AFM). HPLC was used to analyse the entrapment efficiency and drug loading rate of EGCG The amount of folate conjugation on the BSANP was determined by quantitative ultraviolet (UV) spectrophotometer analysis. The targeting ability to PC-3 was observed using laser scanning confocal microscope (LSCM) and fluorophotometer microscope. And the activity of FA-EGCG-BSANP was mensurated by MTT method. The morphology and particle size distribution of FA-EGCG-BSANP were uniform and even with the mean particle size of 200 nm. The entrapment efficiency and loading rate of EGCG were (81.5 +/- 1.8) % and (29.3 +/- 0.6) %, respectively, and the amount of folate conjugation was 18.363 microg x mg(-1) BSA. The FA-EGCG-BSANP uptakes by cultured PC-3 cells were 23.65 times the amount of EGCG-BSANP in a concentration dependant manner. The lethality of PC-3 cells treated with FA-EGCG-BSA was 82.8%, while those treated with EGCG and EGCG-BSANP were 58.6% and 55.1%, respectively. And lethality of PC-3 cells was positively correlated with the nanoparticles uptake amount. FA-EGCG-BSANP can significantly promote EGCG to PC-3 cells sites and improve their efficacy, which is considered to an experimental foundation for further research on its activity, targeting ability and metabolism in vivo.
