The optimized cultural medium of fermentation for Candida sp.mutant strain YQ5 to produce S-adenosylmethionine was studied.The results of single factor experiment showed that the most favorable pH value,carbon source,nitrogen source organic nutrient is 6.0,8% sucrose,1.5% tryptone and 2% yeast extract,respectively.As to inorganic salts,MgSO4?7H2O,CaCl2,FeSO4?7H2O,CoCl2,CuSO4?5H2O,H3BO3 could improve accumulation of the intercellular SAM.The ingredients of the culture medium are also opti-mized by the orthogonal experiment.Fermentation for 48 h under the optimal condition resulted in AdoMet production at 1740.0 mg/L.

An HPLC method for the determination of geniposide concentration in mouse plasma was developed and the pharmacokinetics after intranasal administration of Xingnaojing microemulsion (XNJ-M) and mPEG2000-PLA modified Xingnaojing microemulsion (XNJ-MM) were investigated. Eighty mice were treated by XNJ-M and XNJ-MM nasally. The plasma samples were collected at different times and the drug in samples was detected by HPLC. The pharmacokinetic parameters were calculated by the software of Kinetica. The pharmacokinetic parameters of geniposide of XNJ-M were C(max) (4.36 +/- 2.69) mg x L(-1), t(max) 1 min, MRT (29.73 +/- 4.54) min, AUC (53.63 +/- 14.03) mg x L(-1) x min. The pharmacokinetic parameters of geniposide of XNJ-MM were C(max) (9.75 +/- 4.14) mg x L(-1), t(max) 1 min, MRT(22.34 +/- 2.90) min, AUC (131.87 +/- 40.13) mg x L(-1) x min. Geniposide can be absorbed into blood in a higher degree after intranasal administration with XNJ-MM compared to XNJ-M, which maybe caused by its less irritating and more absorption.

OBJECTIVETo observe the effect of Cangfu Congxian Decoction (CCD) on oxidative stress in granulosa cells of polycystic ovary syndrome (PCOS) patients.

METHODSForty PCOS patients underwent in vitro fertilization-embryo transfer (IVF-ET) were assigned to the treatment group and the control group 1 according to random digit table, 20 in each group. Patients in the treatment group took CCD (200 mL, once in the morning and once in the afternoon) 2 months before IVF-ET, while those in the control group 1 took no Chinese medical decoction. Recruited were another 20 patients undergoing IVF-ET for tubal factors (as the control group 2). The clinical effect of IVF-ET were observed, including oocyte retrieval number, 2 pronuclear (2PN) fertilization rate, good quality embryo rate, clinical pregnancy rate, and ovarian hyperstimulation syndrome (OHSS) induced transplantation cancel rate. The expression of relative oxygen species (ROS) in granulosa cells was detected using cell immunofluorescence combined with confocal microscopy and FCM.

RESULTSCompared with the control group 1, occyte retrieval number, 2PN fertilization rate, and good quality embryo rate increased in the control group 2 and the treatment group (P <0. 05). OHSS induced transplantation cancel rate decreased in the control group 2 (P < 0.05). Fluorescence intensity of ROS decreased in the treatment group and the control group 2, as compared with the control group 1 (P < 0.01).

CONCLUSIONCCD increased good quality embryo rate by down-regulating the expression of ROS protein in ovarian granulosa cells, and correcting in vivo oxidative stress.

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.

Background Eicosapentaenoic acid(EPA)function as the critical lipid mediators involved in several biological events in human body and play important role in suppressing the genesis of vascular endothelial growth factor (VEGF),migration and proliferation of vascular endothelial cells.Many ocular diseases were proved to be associated with neovascularization.Objecfive The purpose of this study was to investigate the inhibitory effect of EPA on the proliferation of human umbilical vein endothelial cells (HUVEC) indueed by VEGF. Methods HUVEC strain was cultured and passaged,and difierent concentrations of EPA were added to the medium with and without VEGF.The cultured cells were identified by antiofactor Ⅷ polyclonal antibody.The suppressing role of different concentrations of EPA on the proliferation of VEGF-induced or-uninduced HUVEC was assessed by MTT method.The influence of difierent concentrations of EPA on the cellular cycle of VEGF-induced HUVEC was assayed using flow eytometry.The expression of Flk-1,a receptor of VEGF,in the HUVEC Was detected by immunohistochemistry. Results Cultured HUVEC showed the ftlsiform in shape and presented with the cobblestone-like arrangement with the positive response for Ⅷ factor-related antigen.Various concentrations of EPA showed obviously inhibitory effect on VEGF-induced or-unindueed HUVEC at a dose-dependent manner (F=23.072.P=0.000).The inhibitory ability of EPA on VEGF-induced HUVEC was stronger than VEGF-uninduced HUVEC(F=41.417,P=0.000).In 24,48 and 72 hours,the action of EPA on the proliferation of HUVEC was gradually enhanced with the prolong of time(F=1.495,P=0.236).Cell cycle analysis indicated that EPA arrested VEGF-induced HUVEC in G0/G1 phase.The ratio of HUVEC in G0/G1 phase in EPA group was(75.83±1.56)%,and that in control groups was(68.62±1.44)%,showing a significant difference between them(t=-5.88,P=0.00),and no apoptosis of HUVEC was found in both groups.Flk-1 was strongly expressed in the cellular nucleus and cytoplasm in control group.However,the positive expressing intensity of Flk-1 in the HUVEC weakened,and the positive cell number was evidently less in EPA group. Conclusion EPA can inhibit the proliferation of VEGF induced HUVEC through arresting the synthesis of DNA of HUVEC and downregulate the expression of Flk-1 in HUVEC.These results suggest that EPA might exert an antiangiogenic effect.

OBJECTIVETo observe the efficacy of treatment of acute leukemia by Shengfu Injection (SFI) in combination with chemotherapy and the effect of treatment on T-lymphocyte subsets (CD4, CD8, CD4/CD8), serum interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha).

METHODSSixty-one patients with acute leukemia of initiatory treating were randomly divided into two groups, the 31 patients in the treated group were treated with SFI plus chemotherapy and the 30 patients in the control group treated with chemotherapy alone. The remission rate, changes of absolute number of peripheral mature neutrophils, T-lymphocyte subsets, serum levels of IL-6 and TNF-alpha before and after treatment were observed.

RESULTSThe remission rate was higher in the treated group than that in the control group but the difference was insignificant (P > 0.05). The restoring of peripheral mature neutrophils in the treated group was higher than that in the control group, from the 3rd week of treatment, the difference was significant (all P < 0.05). CD4 and CD4/CD8 ratio after treatment increased in both groups, the increment was more obvious in the treated group than that in the control group significantly (P < 0.05). Serum levels of IL-6 and TNF-alpha lowered in both groups after treatment significantly(all P < 0.01), but the decrement was greater in the treated group with significant difference to the control group (P < 0.05).

CONCLUSIONSFI could improve and regulate the immune function in acute leukemia patients undergoing chemotherapy and enhance the therapeutic effect.
