Objective To explore the impact factors for post-thaw embryo survival rate and clinical pregnancy rate in frozen-thawed embryo transfer program. Methods The clinical data of 573 cycles of frozen-thawed embryo transfers were retrospectively analysed. Groups were divided according to the pre-freeze embryo quality, pre-freeze embryonic developmental stage, frozen-thawed embryo quality and cryopreservation technique, respectively, and post-thaw embryo survival rates and/or clinical pregnancy rates were compared among groups. Results The clinical pregnancy rate of high quality pre-freeze embryo was significantly higher than that of low quality pre-freeze embryo (31.8% vs 20.0%) (P< 0.05). There was no significant difference in the post-thaw survival rates and clinical pregnancy rates between embryos frozen at day 2 of ferrtilization and those frozen at day 3 of ferrtilization(79. 1% vs 82.9% and 25.5% vs 31.2%, respectively) (P>0.05). The clinical pregnancy rates of the transfer cycles only with fully intact embryos and with mixed embryos were significantly higher than that only with partially damaged embryos(36.7% vs 24.1% and 29.2% vs 24.1%, respectively)(P<0.05). The post-thaw survival rate and post-thaw high-quality embryo rate were significantly higher in those processed with modified cryopreservation technique than in those processed with original cryopreservation technique (82.0% vs 66.3% and 50.0% vs 27.5%, respectively)(P<0.05). Conclusion Pre-freeze embryo quality, post-thaw embryo survival rate and post-thaw embryo quality have a positive correlation to subsequent clinical pregnancy rate. Favorable cryopreservation technique may ensure the success of post-thaw embryo recovery and transfer.

BackgroundHuman retinal gliocytes play an important role in proliferative diseases,which are the basis of in vitro studies.Researchers have cultured human retinal gliocytes in the past.In our study,we found that the cells we cultured presented a unique shape different from those by other researchers.ObjectiveThis study was to design to produce a new culture and purification method for retinal gliocyte in vitro.Methods Retinal tissue was isolated from human eyeballs and digested using the two-step digestion method (2% pancreatin and 0.133%collagenase Ⅵ) to harvest the retinal glio cytes.The cells were collected and cultured in endothelial cell-targeted nutrient culture containing 10% fetal calf serum and supplemented with β-endothelial cell growth factor (ECGF) and sodium heparin,and the culture dishes were coated with fibronectin(FN) to promote the attachment of retinal gliocyte.During the culturing process,the gliocytes were identified by the observation of morphological characteristic and regular histological examination.The identification of the cells also was performed by immunochemistry targeting glial fibrillary acidic protein (GFAP),Vimentin,neuron specific enolase ( NSE ),S-100,CD34,and Ⅷ factor.Results Retinal gliocytes were isolated successfully from the human retina by the two-step digestion method.Primary cultured cells attached after 72 hours and achieved confluency between day 9 and 10 that were aligned petaliform in shape.Regular histological examination after H&E staining showed blue cell nuclei and light red cytoplasm.The target cells presented with strong responses for GFAP and Vimentin and no response for NSE,S-100,CD34 and Ⅷ factor.ConclusionsLarge amount of purified human retinal gliocytes can be obtained by two-step digestion and cultured in endothelial cells-targeted culture medium supplemented with β-ECGF and sodium heparin in plates coated with FN.The cultured cells expressed markers for retinal gliocytes.However,specific features of these cells remain to be further elucidated.

An alkaline catalase has been purified and characterized from a slightly halophilic and alkaliphilic bacterium Bacillus sp. F26. The purification was performed with a four step procedure consisting of ammonium sulfate precipitation, ion exchange, gel filtration and hydrophobic interaction chromatography, and finally achieved a 58.5-fold-purifying over the crude extract. The purified catalase was composed of two identical subunits with a native molecular mass of 140 kD. The native enzyme showed the typical Soret band appearing at 408 nm. The pyridine hemochrome spectrum indicated the presence of protoheme IX as the prosthetic group. The apparent Km value for enzyme activity on H2O2 was calculated to be 32.5 mmol/L. The activity of this catalase was not reduced by dithionite but was strongly inhibited by cyanide, azide, and 3-amino-1,2,4-triazole (the specific inhibitor of monofunctional catalase). No peroxidase activity of this enzyme was detected when using o-dianisidine, diaminobenzidine (DAB) and p-phenylenediamine as electron donor. Moreover, the N-terminal sequence of this catalase exhibited substantial similarity to the monofunctional catalase subgroup rather than catalase-peroxidase or Mn-catalase one. Therefore, we characterize the purified catalase as a monofunctional catalase. Besides, this monofunctional catalase was thermosensitive and its activity exhibited pH-independent over pH 5-9 but showed a sharp maximum at pH 11. An activity half-life of approximately 49 h was measured when the enzyme was incubated at 20 degrees C and pH 11. To our knowledge, pH 11 is the most alkaline condition for optimum catalysis and enzyme stability among the catalases reported up to now. Furthermore, this monofunctional catalase also showed excellent halo-alkali-stability with a half-life of approximately 90 h at 0.5 mol/L NaCl and pH 10.5. On the other hand, so far as we know, the characterized catalase is the first dimeric monofunctional catalase from alkaliphiles and is also the first monofunctional catalase derived from a natural soda lake, which could partially reflect the oxidative stress response in the corresponding environment.

The purpose of this study is to evaluate the anti-aging effects and reveal the underlying mechanism of Scutellaria baicalensis Georgi ethanol extract (SBG) in D-galactose-induced rats. Fifty rats were randomly divided into five groups: vehicle control group, D-galactose group, and D-galactose combined with 50, 100, 200 mg x kg(-1) SBG. A rat aging model was induced by injecting subcutaneously D-galactose (100 mg x kg(-1)) for ten weeks. At the tenth week, the locomotor activity (in open-field test) and the learning and memory abilities (in Morris water maze test) were examined respectively. The urine was collected using metabolic cages and analyzed by high-resolution 1H NMR spectroscopy combined with multivariate statistical analyses. The SBG at doses of 50, 100 and 200 mg x kg(-1) treatments groups could significantly ameliorate aging process in rats' cognitive performance. The 50, 100, 200 mg x kg(-1) SBG regulated citrate, pyruvate, lactate, trimethylamine (TMA), pantothenate, β-hydroxybutyrate in urine favorably toward the control group. These biochemical changes are related to the disturbance in energy metabolism, glycometabolism and microbiome metabolism, which is helpful to further understanding the D-galactose induced aging rats and the therapeutic mechanism of SBG.

AIM AND METHODSTo observe the effect of myocardial mitochondrial L-arginine (L-Arg)/nitric oxide (NO) system on mitochondrial Ca2+ transport by using purified rat mitochondria and incubation of them in vitro.
RESULTSCompared with control group, incubation of mitochondria with L-Arg (10(-4) mol/L, NO substrate) or sodium nitroprusside (5 x 10(-7) mol/L, the donor of exogenous NO, SNP) increased significantly mitochondrial NO2- (66% and 89%, P < 0.01), respectively, and decreased the Ca2+ content (40% and 54%, P < 0.01). After L-Arg or SNP treatment, mitochondrial Ca2+ uptake were decreased by 67% and 85%, respectively (P < 0.01), vs control. The rate of mitochondrial Ca2+ release decreased by 11% and 8%, respectively (P < 0.01). When L-NAME (NO synthase inhibitor) was incubated with mitochondria and the L-Arg together, it inhibited the effects of L-Arg, NO2 on the mitochondrial NO2 formation, Ca2+ content descending, and decrease of Ca2+ uptake and release.
CONCLUSIONThe data suggest that myocardial mitochondrial L-Arg /NO systems take part in the regulation of cardiomyocytes Ca2+ transportation.
