BACKGROUND: Nestin is a specific antigen of neural stem cells which widely expressed in lesion of nervous system and brain regeneration.Thus,nestin expression is commonly used to assess whether lesion or damage of the nervous system can promote neural regeneration.OBJECTIVE: To investigate the effects of erythropoietin(EPO)on nestin expression in neural stem cells after hypoxia-ischemia brain damage(HIBD)in neonatal rats from the angles of neural regeneration and activation of neural stem cells.METHODS: HIBD model was established by ligation of the right common carotid artery along with 2-hour 8% hypoxia exposure in neonatal rats.The control group was not subjected to hypoxia-ischemia,and the right common carotid artery was dissociated.The treatment group received an intraperitoneal injection of recombinant human erythropoietin(rh-Epo,5 000 IU/kg)once a day for three days after hypoxia/ischemia,while the two other groups intraperitoneally received normal saline at the same time.In each group,rats were randomly executed immediately,at 4,7,14 days after operation(n = 8).The nestin expression in hippocampal dentate gyrus region was examined by immunohistochemical staining and image quantitative analysis respectively.RESULTS AND CONCLUSION: The number of nestin-positive cells was significantly increased in HIBD group compared to control group at all time points(P < 0.05),and it was also significantly increased in treatment group than the other two groups at all time points(P < 0.05).The numbers of nestin-positive cells in hippocampal dentate gyrus region were significantly increased,and peaked on day 7 after operation in the three groups.The results showed that exogenous rh-Epo could enhance the expression of nestin in hippocampal dentate gyrus region of neonatal rats with HIBD,and promote the proliferation of neural stem cells,rh-Epo plays an important role in the regeneration and repair of neurocytes damaged by hypoxia-ischemia.

Objective To investigate the remineralization effects of the Aominqing dental desensitizer and the fluoride dentifrice on the demineralized enamels. Methods Sixty-three teeth were randomly divided into three groups after demineralization , then was remineralized for eight days by using Aominqing dental desensitizer, fluoride dentifrice (1.1 g/L), and deionized water, respectively. The thin sections of teeth were analyzed under the con-focal laser scanning microscope (CLSM). The morphology of the surface of teeth was observed under the scanning electron microscope (SEM). Results Under CLSM, the evaluation parameter area of the fluorescent lesion (A,μm2) processed by Aominqing and by fluoride was (3.19 ± 0.19) × 104, (3.61 ± 0.26) × 104 μm2, respectively. The total fluorescence (TF) was (0.61 ± 0.09) × 106, (0.89 ± 0.15) × 106, average fluorescent of the lesion(AF) was (18.98 ± 1.56), (24.65 ± 2.39), and the above parameters were all less than those in the blank control group [A=(4.89 ± 0.24) × 104 μm2,TF=(1.78 ± 0.21) × 106, AF = 36.29 ± 2.57] (P < 0.01). The evaluation parameters in the Aominqing group were less than those in the fluoride dentifrice group(P < 0.05). Under SEM, the surface of the group processed by Aominqing was the smoothest, compared to the fluoride dentifrice group and the blank control group. Conclusions Both Aominqing dental desensitizer and fluoride dentifrice (1.1 g/L) have the remineralization effects on the demineralized enamels, and the former has a stronger effect.

ObjectiveTo investigate the rule of changes of the soleus mass and expression of myosin heavy chain (MHC) isoforms mRNA.Methods40 female Wistar rats were divided randomly into the control group and three spinal cord transection (ST) groups, ST7, ST15, and ST30 with 10 animals in each group. Rats in ST groups were subjected to a complete ST between T8 and T10 levels. The right soleus was dissected and weighed at 7, 15, 30 days after ST, and the expression of MHC mRNA isoforms was measured by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR).ResultsThe Absolute and relative soleus masses in three ST groups were lower significantly than those of control group (P<0.05). The soleus mass in ST15 and ST30 groups were lower than that of ST7 group (P<0.05). The soleus of control group predominantly expressed MHC-I and some MHC-IIa, whereas the soleus began to express MHC-IIx and MHC-IIb after ST, except for MHC-I and MHC-IIa. ST induced consistently down-regulation of MHC-I mRNA and up-regulation of MHC-IIx and MHC-IIa at three time points after ST. The level of MHC-IIb mRNA expression was very low at three time points after ST.ConclusionST can influence the soleus mass at early stage after ST. ST induces a shift toward a faster muscle phenotype from slow to fast MHC isoform. MHC demonstrates plasticity in response to decrease neuromuscular activation.

Objective To investigate the effects on pregnancy outcome and neonate by artificial shrinkage by microsucting the fluid of expanded blastocysts before vitrification using glass micropipette (GMP).Methods From Jan.2006 to Dec.2009, 342 vitrified-thawed blastocyst cycles from patients that performed in vitro fertilization-embryo transfer (IVF-ET) or intracyteplasmic sperm injection ( ICSI ) were enrolled in this study in Reproductive Medicine center, Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region.Three hundred and fourteen cycles of expanded blastocysts were artificially shranked by microsucting blastocoelic fluid with a micro-needle before vitrification as artificial shrinkage group, in the mean time, 28 cycles without artificial shrinkage were chosed as control group.The survival rate, implantation rate, clinical pregnancy rate and transfer canceled rate were compared between artificial shrinkage group and control group.Among pregnant women, the miscarriage rate, live birth rate, congenital birth defect rate, neonatal weight and gestational age were compared with those of fresh embryo transfers in 520 cycles.Results The blastocyst survival rate, implantation rate and clinical pregnancy rate were 95.3%(403/423), 38.0% ( 153/403), 44.6% (140/314) in artificial shrinkage group and 64.3 % (27/42),7.4% (2/27), 7.1% (2/28) in control group, respectively, which reached statistical difference (P＜0.05).The transfer canceled rate was 0 in artificial shrinkage group and 25.0% (7/28) in control group, which also reached statistical difference ( P ＜ 0.05 ).Among pregnant patients, the miscarriage rate of 18.2% (10/55), live birth rate of 80.0% (44/55), gestational age of (38.2 ± 1.3) weeks, congenital birth defect rate of 2.1% (1/47), birth weight of newborns of (2989 ±640) gram in artificial shrinkage group were not significantly different with 17.5% (91/520), 74.0% (385/520), (37.9 ±2.3) weeks,1.7% (8/479) and (2856±640) gramin fresh embryo transfer group (P＞0.05).Conclusion Artificial shrinkage by microsucting blastocoelic fluid with a micro-needle before vitrification significantly improved the vitrification effects of expanded blastocyst and no distinct increasing rate of neonates congenital anomality were observed.

In response to viral infection, RIG-I-like RNA helicases detect viral RNA and signal through the mitochondrial adapter protein VISA. VISA activation leads to rapid activation of transcription factors IRF3 and NF-κB, which collaborate to induce transcription of type I interferon (IFN) genes and cellular antiviral response. It has been demonstrated that VISA is activated by forming prion-like aggregates. However, how this process is regulated remains unknown. Here we show that overexpression of HSC71 resulted in potent inhibition of virus-triggered transcription of IFNB1 gene and cellular antiviral response. Consistently, knockdown of HSC71 had opposite effects. HSC71 interacted with VISA, and negatively regulated virus-triggered VISA aggregation. These findings suggest that HSC71 functions as a check against VISA-mediated antiviral response.

Objective To explore the role of CD4+CD25+regulatory T cells(Treg)in the co-culture svstem consisting of T cells and mouse embryo fibroblasts(MEF)infected with murine cytomegalovirus (MCMV)in vitro.Methods A co-culture system of T cells and MCMV infected MEF(MEFMCMV)was established.The viral load in the supernatants was determined by plaque assay.TH1/TH2 differentiation-specific transcription factors T-bet/GATA-3 were assayed by Western blot.The levels of cytokines IL-4,IL-10and IFN-γ in the co-culture supenatants were measured by double-antibody sandwich ELISA.Results After 3 d incubation,the viral load in the supernatants of TdepTreg-MEFMCMC group,in which the T cells depleted Treg(TdepTreg)were co-cultured together with MEFMVMV,was significantly lower than that in MEFMCMV group.And in the co-cultivation of MEFMCMV and T cells without Treg the expressions of T-bet/GATA-3,IL-4,IL-10 and IFN-γ incteased significantly.Compared with the virus content in the TdepTreg-MEFMCMV group,the MCMV load in the"add-on Treg group"increased and the levels of T-bet/GATA-3 and IFN-γ were lower,and the expression of IL-4 didn't show any significant difference. Compared with the level of IL-10 in the TdepTreg-MEFMCMV group,the IL-10 level in the"add-on TREG group"didn't show any significant differece when the Treg ratio among total T cells was 1%～2%,and increased significantly when the Treg ratio was more than 5%.These eflfects were all correlated with Treg ratios in a dose-dependent manner.Conclusion MCMV infected MEF can induce the proliferation and activation of effector T cells,but Treg can inhibit the T cell-mediated protective effect on MCMV infection.
