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.

Integrins are a family of cell surface glycoproteins that contribute to a variety of biological functions, including cell growth, migration, proliferation and morphology. In addition, integrins also play the important roles in pathological process. Several viruses have been showed to use integrins as receptors or co-receptors to infect host cells.This article mainly reviews the progress on integrins and their roles in FMDV infection.

Receptors are primary determinant of viral tropism and disease pathogenesis.Heparan sulfates (HS)are ubiquitous,polyanionic carbohydrate chains linked to core proteins in cell membranes and ex- tracellular matrices of all eukaryotes.HS have also been demonstrated to function as receptors or co-receptors for a number of different viruses.To date,HS and four RGD-dependent integrins,?v?3,?v?6, ?v?1,and?v?8 have been reported to serve as receptors for Foot-and-mouth disease virus(FMDV).Different receptors may be used to interact with host cells during FMDV infection.Studies on the structure and function of receptors are very important for understanding the interaction between host cells and FMDV. Here,We mainly reviews the progress on the biological characteristics of HS and its roles in FMDV infection.

Objective To explore the correlation between serum hepatitis B virus (HBV) X antigen/antibody (HBxAg-wild/HBxAb-wild,and HBxAg-mutant/HBxAb-mutant) and the disease progression in patients with chronic HBV infection.Methods A direct enzyme immunosorbent asssay (ELISA) was performed to detect HBxAb using recombinant antigen,and a double antibody sandwich ELISA assay to detect HBxAg using monoclonal antibody and specific rabbit polyclonal antibody.HBxAg-wild/HBxAb-wild and HBxAg-mutant/HBxAb-mutant were tested in sera from cases at different stages of chronic HBV infection.A chi-square test was employed to examine statistical significance.Results The positive rates of HBxAg-wild and HBxAg-mutant in the chronic asymptomatic HBV carriers,chronic hepatitis,hepatitis B-related cirrhosis and liver cancer were 6.2％ (2/32),10.7％ (3/28),28.6％ (6/21),43.6％ (17/39) and 3.1％ (1/32),10.7％ (3/28),33.3％ (7/21),48.7％ (19/39),respectively.The positive rates of HBxAb-wild and HBxAb-mutant in the above mentioned groups were 6.2％ (2/32),21.4％ (6/28),38.1％ (8/21),53.8％ (21/39)and 6.2％ (2/32),25.0％ (7/28),42.9％ (9/21),61.5％ (24/39) respectively.The positive rates of HBxAg-wild and HBxAg-mutant were not significantly different among the above groups (x2 =0.871,0.780,0.565 and 0.317,respectively; all P＞0.05) ; The positive rates of HBxAb-wild and HBxAb-mutant were also similar among all the groups (x2 =0.780,0.709,0.580 and 0.210,respectively; all P＞0.05).The positive rates of HBxAg-wild,HBxAb-wild,HBxAg-mutant,HBxAb-mutant in patients with low viral loads (HBV DNA＜1 × 104 copy/mL) were 36.5％ (23/63),44.4％ (28/63),42.9％ (27/63) and 54.0％ (34/63),respectively,those in patients with high viral loads (HBVDNA≥1×104 copy/mL) were 8.8％ (5/57),15.8％ (9/57),5.3％ (3/57) and 14.0％ (8/57),respectively.The positive rates of HBxAg and HBxAb were significantly higher in cases with low viral loads than those with high viral loads (x2 =12.869,11.522,22.556 and 20.976,respectively; all P＜0.05).The positive rates of HBxAg-wild,HBxAb-wild,HBxAg-mutant,HBxAb-mutant in the HBeAg positive group were 21.7％ (18/83),30.1％ (25/83),22.9％ (19/83) and 32.5％ (27/83),respectively,while those in the HBeAg negative group were 27.0％ (10/37),32.4％ (12/37),29.7％ (11/37) and 40.5％ (15/37),respectively.No significant difference of HBxAg/HBxAb positive rates between HBeAg positive group and HBeAg negative group was noticed (x2 =0.408,0.064,0.638 and 0.722,respectively; all P＞0.05).Conclusions The antigenicity and specificity of HBV X protein remains similar after the occurrence of A1762T/G1764A double mutant in X gene.It is also found that the positive rates of HBxAg and HBxAb increase with disease progression.HBxAg/HBxAb might be promoting factors for tumorigenesis in chronic HBV infection.HBxAg and HBxAb might have negative influence on HBV replication.

The stability of melittin in different solvents (water, deoxygenated water, physiological saline, PBS, 50% ethanol, ethanol, glycerol)was studied and the results showed that the stability of melittin is not influenced by light, temperature and pH in 50% ethanol, which melittin can be completed dissolved when compared with ethanol and glycerol, in such, 50% ethanol was chosen as solvent storage when measured content of melittin. Then the effect of different concentrations of PBS, the pH of PBS and rat skin ho- mogenates were tested, and the results showed that melittin was degraded rapidly at low concentration solution and low ionic strength. Increasing pH of PBS and rat skin homogenate can accelerate the degradation of melittin. These researches provide an experimental ba- sis for further study of melittin.

OBJECTIVETo study the effect and mechanism of Bushen Tiaojing Recipe on improving oocyte and embryo qualities in patients undergoing in vitro fertilization-embryo transfer (IVF-ET) at the super-ovulatory cycle.

METHODSFifty-eight tubal infertility patients undergoing IVF-ET were randomly assigned to two groups. Thirty patients in the treatment group were treated with Bushen Tiaojing Recipe and GnRHa/FSH/hCG, and twenty-eight patients in the control group were treated with GnRHa/FSH/hCG. Contents of GDF-9 in the mature follicular fluid were detected by Western blot. The expressions of GDF-9 in granulose cells were detected by Real-time PCR. The dose of gonadotropin (Gn), the number of oocytes obtained, the fertilization rate, the oocyte cleavage rate, the high quality embryo rate, and the pregnancy rate were compared.

RESULTSThe contents of GDF-9 in the follicular fluid and its expression in granulosa cells were significantly higher in the treatment group than in the control group (P<0.05). The number of oocytes obtained, the fertilization rate, the high quality embryo rate, and the pregnancy rate were significantly higher in the treatment group than in the control group. There was no significant difference in the dose of Gn or the oocyte cleavage rate.

CONCLUSIONSBushen Tiaojing Recipe could improve the pregnancy rate of IVF-ET. Its mechanism might be possibly through regulating the GDF-9 contents in the follicular fluid and granulosa cells.
