Objective To compare the biocompatible and osteconduetian behavior of the high-density porous polyethylene and hydroxyapatite/ultra-high molecular weight polyethylene. Methods Osteoectomy of the upper orbital rim was performed on 60 adult Japan rabbits. The animals were randomly divided into 3 groups with 20 of each. The hydroxyapatite/ultra-high molecular weight polyethylene, high-density porous polyethylene was implanted to the upper orbital defect of the animals in respective group. Animals were sacrificed at the 1st, 2nd, 4th and 8th weeks. Alkaline phosphatase (ALP) and Osteocalcin (OC)in the HDPE and hydroxyapatite/ultra-high molecular weight polyethylene was also detected. Result During the experimental period of 8 weeks, there was no implants extrusion or displacement. Fibrous tissue and new vessels grew into HDPE were obviously elder than those grew into hydroxyapatite/ultra high molecular weight polyethy-lene. Alkaline phosphatase and osteocalcin contents has great difference, HDPE group is the best, followed by HA combination artificial group (P<0.05). Conclusions High-density porous polyethylene and hydroxyapatite/ultra-high molecular weight polyethylene are both good orbital reconstruction materials, they all have good biocompatiblity and osteoconductian, but high-density porous polyethylene is better than hydroxyapatite/ultra-high molecular weight polyethylene in osteoconductian.

The investigations on the interactive relationships of DNA replication, damage repair and recombination have been locating in the frontline and becoming one of the hotspots in today's life science research. More and more studies show that the processes of DNA replication, damage repair and recombination are both independent and interdependent in the molecular level. These pathways coordinate and conform each other through interactions of many critical proteins in the pathways, by which DNA molecules, known as genetical materials, can be well maintained in cell and faithfully transferred through cellular generations. By using E. coli as a model system, the recent progresses and the possible rules underlying E. coli DNA replication, repair and recombination have been analyzed. As it is believed that the researches on E. coli DNA replication, repair and recombination may be capable of providing clues to the eukaryotic research based on the universal conservations of the critical proteins in the pathways.

The aim of this study is to investigate the effect of fluoxetine (FLX) on the expressions of BDNF and Bcl-2 in the hippocampus, the amygdala and the prefrontal cortex of conditioned fear (CF) model mice. Forty eight mice were randomly divided into three groups, normal control group, CF stress group and FLX-pretreated CF group. The FLX-pretreated CF group was given FLX (10 mg x kg(-1) x d(-1)) for 7 days before CF stress. After CF stress model was established, all mice were given behavioral experiments to test whether FLX impaired or improved the auditory and contextual fear conditioning. Then mice were sacrificed. The expressions of BDNF and Bcl-2 were detected by Western blotting. The results showed that the freezing time of FLX-pretreated CF group was significantly lower than that of CF group; FLX pretreatment up-regulated the expression of Bcl-2 in the hippocampus at 1 d after CF stress (P < 0.001), but no significant differences was observed at 7 d; BDNF significantly increased in the hippocampus at 7 d (P < 0.001), but no differences at 1 d; the expressions of BDNF and Bcl-2 in the amygdala and the prefrontal cortex were of no obvious differences between CF group and FLX-pretreated CF group at 1 d or 7 d after CF stress. Parallel to these changes, pretreatment with FLX could affect histopathologic changes induced by CF stress. Furthermore, the results indicated that FLX pretreatment could protect against CF stress-induced neurological damage via the activation of BDNF and Bcl-2 in hippocampus.

Objective To investigate the effective administration model for gestational diabetes mellitus (GDM) in the community. Methods In a prospective study, the 75 g oral glucose tolerance test (OGTT) was performed in 4 713 resident pregnant women over 20 years old who received antenatal care in a general hospital or a special hospital from Sep. 2011 to Aug. 2012. Five hundred and thirty-three pregnant women were diagnosed as GDM, 198 patients who labored in a general hospital were enrolled in thegroup A , and the rest who labored in a special hospital were enrolled in the group B. 198 cases with non-GDM were enrolled in the group C. Results The incidence of GDM during this study period was 11.3%. The maternal age , gestationl weeks and OGTT results of patients in the three groups were significantly different (P < 0.05). With the increase of maternal age of pregnant women, the blood glucose increased while the gestationl weeks descreased. No significant differencees were shown in prevalence of polyhydramnios, hypertensive disorder complicating pregnancy, premature labor, macrosomia , fetal growth restriction and neonatal asphyxia among the three groups (P > 0.05). However, significant differences were found in the incidence of postpartum hemorrhage and cesarean section. The incidence of postpartum hemorrhage increased significantly in the patients of group B (χ2= 7.156, v = 2, P = 0.028). The incidence of cesarean section increased significantly in the patients of group A (χ2= 63.592, v = 2, P = 0.000). Conclusion Establishing an effective administration model for gestational diabetes mellitus in the community could control the incidence of GDM associated complications.

Objective To investigate the relationship between the changes of portal pressure gradient after selective devascularization with postoperative complications and recurrent bleeding of gastroesophageal varix in patients of portal hypertension. Methods The clinical data of 135 cases of portal hypertension undergoing selective devascularization was collected. Portal pressure gradient was measured before splenectomy and after selective devascularization, and was analyzed against postoperative complications and recurrent bleeding. Results In this study, 135 patients of portal hypertension underwent selective devascularization, two cases died during perioperative period ( 1.5% ). Postoperatively patients were divided into three groups based on PPG ＜ 12 mm Hg after selective devascularization (62 cases), HVPG ≥ 12 mm Hg but a more than 20% of decrease off the pre-splenectomy baseline (41 cases) and HVPG ≥12 mm Hg with less than 20% of decrease from the baseline (32 cases). The postoperative complications between the three groups were of no significant difference ( P ＞ 0. 05 ). The 1,2,3 year cumulative rate of no variceal rebleeding of the three groups were 100% vs. 100% vs. 95%; 100%vs. 97% vs. 90%; and 100% vs. 93% vs. 87% (x2 =6. 859, P = 0. 032). COX regression analysis indicated portal vein pressure gradient was an independent prognostic factor of variceal bleeding recurrence (P=0.002). 1,2,3 year cumulative survival rates of the three groups were 100% vs. 100% vs. 94%; 98% vs. 95% vs. 92%; 97% vs. 93% vs. 88%, there were no significant difference among the three groups ( x2 = 2. 917, P = 0. 233 ). Conclusions The decrease in the PPG after selective devascularization is a predictor for the risk of rebleeding but not for survival after selective devascularization.
