Optic nerve is composed by the axonal of retinal ganglion cells,there are no Schwann cells around it,and optic nerve belongs to the central nervous,so it cannot regenerate when injuried. In 1985 So and Aguayo have made a success in peripheral nerve retinal transplant,which completely changes the concept that optic nerve injury cannot regenarate. Currently nerve injury recovry has following several methods: use of neurotrophic factor,such as nerve growth factor,ciliary neurotrophic factor and brain-derived neurotrophic factor,etc. These factors could promote the regeneration and repair of retinal ganglion cells; treatment of gene correction and gene regulation,by changing the expression of host gene,reduce the effect due to the disease,slow the progress of the disease course or provide protection against the disease; neural stem cell transplantatin and tissue-engineered Schwann cell transplantion. But these treatments are still at the stage of animal experiment,how timely and effctively reduce the apoptosis and increase the survival rate of ganglion cells,even further promote nerve regeneration and recovery,there is still not a perfect method so far.

The structure, properties and bioactivity of the ceramic coating are also introduced.

Objective To construct a eukaryotic expression vector in Pichia pastoris containing human tissue factor( hTF) gene,in order to achieve high level secretory expression in extracellular.Methods Expression plasmid, pGAPZaA-hTF, was constructed by inserting the synthesized sequence encoding human extracellular tissue factor into yeast expression vector pGAPZaA and transformed into Pichia pastoris SMD1168H with electroporation.Having been selected by Zeocin, transformants containing hTF cDNA were expressed in YPD, extracellular proteins were detected by SDS-PAGE and confirmed by Western bolt.Results Successfully constructed the recombinant pGAPZaA-hTF expression system in Pichia pastoris.SDS-PAGE showed that the molecular weight of the expression product was about 37 -40 kDa.Western-blot indicated that it was human extracellular tissue factor.The crude yield of total protein in medium was up to 1 g/L, more than 80% of which was hTF.Conclusion Truncated rTF gene is expressed in Pichia pastoris and the active products are secreted into the medium which have the same activation as the native TF.

AIM: To investigate the regulatory effects of salusins on tensility of microvessle in rats. METHODS: Wistar rats were randomly distributed into six experimental groups as follows: (1) normal saline injection-treated control; (2) salusin ?; (3) salusin ?; (4) noradrenaline; (5) noradrenaline+salusin ?; and (6) noradrenaline+Salusin ?. For recording the microcirculation images in the mesentery, the intestinal loop was mounted on the stage of an intravital microscope equipped with a TV camera. Temporal changes in internal diameter of arterioles and venules were measured by computer using the Image-Pro software. RESULTS: Salusin ? (10 -5mol/L) dilated arterioles directly and the dilation up to the peak at 3 min [(25.56?4.30) vs (24.49?4.27)?m, P0.05). Salusin ? has no effects on internal diameter directly and NA-induced contraction of microvessles. CONCLUSION: Salusin ? dilated mesenteric arterioles and inhibited NA-induced contraction of microvessles in rats.

Objective To explore the optimal time for clinical interventions on full-term or nearterm pregnant women with premature rupture of membranes(PROM). Methods A retrospective study was conducted on clinical data of 903 healthy, full-term or near-term (gestational age ≥ 35 weeks), singleton pregnant women with PROM, who admitted to our hospital from January 1, 2005 to December 31, 2009. All subjects were divided into 6 groups: women in group 1 were those fell into spontaneous labor within 6 h after PROM (n=269, 29.8%); women in group 2 were in spontaneous labor between 6 to 12 h after PROM (n= 161, 17.8%) ; women in group 3 were in spontaneous labor at 12 to 24 h after PROM (n = 75, 8. 3%); In group 4 oxytocin was administered for induction for women not in labor at 6 to 12 h after PROM (n= 124, 13.7%) ; Group 5 included those women who were not in labor at 12 to 24 h after PROM and oxytocin induction was offered (n=98, 10. 9%);Group 6 consisted of those women who were not in labor over 24 h after PROM and oxytocin induction was offered (n = 176, 19. 5%). The maternal and neonatal complications and outcomes of all pregnancies were reviewed and compared. Results Among the 903 cases, the total number of women without any medical interventions was 681, among which 505 (74.2%) fell into spontaneous labor, including 430 (63.2%) within 12 h with a cesarean section rate(CSR) of 20.7%(89/430), 75 (11.0%) at 12-24 h after PROM with the CSR of 50.7% (38/75), and 176 (25.8%) did not go into labor spontaneously (group 6) with a CSR of 70. 5% (124/176). (2) Among the 930 women, 398were induced at 6, 12 and 24 h after PROM. The CSR, incidence of intrauterine infection, puerperal morbidity and perinatal mortality rate in group 5 were significantly lower than those of group 6 [CSR:52.0%(51/98) vs 70. 5%(124/176); intrauterine infection: 6. 1%(6/98) vs 22. 7%(40/176);puerperal morbidity: 6. 1% (6/98) vs 19.9% (35/176); perinatal mortality: 7. 1% (7/98) vs 20.5%(36/176),all P＜0. 01], but no difference was found in the incidence of postpartum hemorrhage [1.0%(1/98) vs 4.0%(7/176), P＞0.05]. Conclusions Intervention is not recommended within 12 h after PROM in full term or near term gravidas. However, induction of labor should be offered thereafter. However, the CSR and incidence of maternal and neonatal complications rise up if induction of labor postponed to 24 h after PROM.
