AlM:To investigate the visual function in myopia and hyperopia amblyopia whose corrected visual acuity have recovered to normal.METHODS: The visual function of children ( 50 cases ) with amblyopia eyes by binocular vision correction after treatment above 0. 9 was checked. The simultaneous perception, fusion range and distance stereopsis were measured. According to the refractive condition of the children who were divided into group A ( myopia, 20 cases ) and group B ( hyperopia, 30 cases ) . The statistically difference of simultaneous perception, fusion function and stereopsis in two groups was analyzed. RESULTS: Fifteen ( 75%) and twenty - six ( 87%) children got the simultaneous perception in group A and group B respectively, and the differences between two groups were not significant (χ2=0. 454,P>0. 05). Group A had six children ( 30%) and group B had only seven children (23%) with the normal aggregative fusion range, two groups did not show any difference (χ2 =0. 565, P>0. 05). Respectively sixteen (80%),and twenty children ( 67%) had the normal divided fusion range in group A and group B, the recovery rate did not show any significant difference (χ2=0. 740, P>0. 05). Fifteen (50%) and seven ( 35%) patients acquired the far stereoscopic vision in group B and group A respectively, the recovery rate also did not show any significant difference. Normal distance stereopsis of 50 cases had 22 cases ( 44%) , and normal near stereopsis of 50 cases had 13cases ( 26%) Seven (23%) and 6 (30%) children got the normal near stereoscopic vision in group B and group A respectively, and the recovery rate did not show any significant difference (χ2=0. 195, P>0. 05;χ2=0. 295, P>0. 05).CONCLUSlON:After amblyopia treatment, although the children got the normal visual acuity, the binocular vision still can not completely normal in the short term. Myopia and hyperopia factor will not produce significant effect on binocular vision development.

Objective To study the principle of chemokine stromal-dirived factors-1(SDF-1)in acute rejection,we test the expression of CXCR4 which is the receptor of SDF-1 in acute rejection following liver transplantation. Methods needle-biopsy specimens after liver transplantation were divided into four groups according to Banff schema.We analyzed the mRNA level of CXCR4 in each group by RT-PCR.Results In non-rejection group and control group,all samples expressed CXCR4 in small and medium dose.In rejection group,high level expression of CXCR4 related to high degree of acute rejection were found.Conclusion The CXCR4 plays an important role in acute allograft rejection of human liver after transplantation.To restrain the expression of CXCR4 may be au effective method of anti-acute rejection.

Objective To detect Ureaplasma urealyticum (Uu) and Mycoplasma hominis (Mh) in urogenital tract of healthy elementary and high school students,and to determine the biovars and serotypes of Uu isolates.Methods Urine specimens were collected from 957 healthy school children,including 404 elementary school students,260 junior high school students and 293 senior high school students,and submitted for Uu and Mh culture in selective liquid medium.Thc specimens positive for Uu and (or) Mh culture were subsequently subjected to PCR.The biovars and serotypes of Uu were determined.Results Uu was detected in 4.81％ (46/957) of the school children.Among the 46 Uu positive specimens,32 (69.57％) harbored Ureaplasma Parvum (biovar 1 ),14 (30.43％) Ureaplasma urealytieum (biovar 2); 12 (2.97％) were from elementary school students,including 9(75.00％) cases of Ureaplasma Parvum and 3(25.00％) Ureaplasma urealytieum,8(3.08％) were from junior high school students,including 5 cases of Ureaplasma Parvum and 3 Ureaplasma urealytieum,26 (8.87％) were from senior high school students,including 18 (69.23％) cases of Ureaplasma Parvum and 8 (30.77％)Ureaplasma urealytieum.Mh was positive in 9 (0.94％) school students,including 1 elementary school student,1 junior school student and 7 senior high school students.The detection rate of Uu was significantly higher in females than in males in all the 3 groups (elementary school,junior and senior high school) of students.Conclusions Mh and Uu are commensals in urogenital tract of elementary and high school students without symptoms.Ureaplasma Parvum is the predominant biovar in this population,though Ureaplasma urealytieum accounts for a significant proportion,which implies that Uu is commensal in healthy elementary and high school students,and females are more liable to be colonized than males.

The experiment contents were integrated into three parts such as basic skills and verification experiment, systematic experiment and designing experiment. Basic skills and confirmato-ry experiments were performed alone with theory teaching by combination of modern teaching methods and traditional teaching methods, which consisted of “speaking”(experimental principles, methods and main technical points using multimedia), “looking”(demonstrating related operation on teaching website), teachers' demonstration, students' doing experiment independently and summarizing. In this part, the experimental operation skills such as the sterile operation technology, staining technology, microscopy technology and pure culture were emphasized. Systemic experiments would be carried out after completion of the most theory, the experiment time could be adjusted according to the experiment content, and the PBL teaching method was taken in this stage. After the theory teaching of Medical Microbiology was finished, students voluntarily participated in design experiments in the last stage, which were the fusion of scientific research subject and the experimental teaching. From the preview experiment, experiment operation, experiment report, to the final test, the multi-dimensional evalua-tion was implemented throughout the course of experiment teaching.

This study examined the cytotoxicity of a new implant material modified by microarc oxidation technique. Cells on different surfaces of the implant were evaluated 2, 4 and 6 days after treatment. The results showed that cell attachment, cell morphology, and cell proliferation were influenced by the different surface treatments, and a significant increase in the osteoblast cell activity was observed on the porous MAO-Ti coating. Our results suggest that the porous MAO-Ti surface has a better biocompatibility and electrochemical performance than pure titanium surface.

Objective To study the damage of rat articular cartilage induced by different doses of T-2 toxin, and to explore the relationship between mini-dose T-2 toxin and articular cartilage damage. Methods A total of 120 Wistar rats, weighing 50 - 70 g, were randomly divided into four groups according to their body weights: T-2 toxin group 0(control), 100, 200, 300 μg/kg, 30 rats in each group. Animals in the control group were fed standard rat chow, and animals in the three T-2 toxin groups were fed T-2-toxin-contaminated chow (the dose was 100, 200, 300 μg/kg, respectively). After 6 months, rats were euthanized by ether asphyxiation. The bilateral knee joints were collected and section prepared. The articular cartilage was examined by light and electronic microscope. Results Light microscope showed, the rat articular chondrocytes were clear and arranged orderliness in the control group. The rat articular chondrocytes were disarranged in 100 μg/kg T-2 toxin group.Degeneration and necrosis were found in 200 μg/kg group. Chondrocytes were shrunken with hypereosinophilia cytoplasm and fragmented pyknotic nuclei, extensive areas of chondrocyte loss and chondrocyte clones were visible in 300 μg/kg group. Scanning electronic micrograph(SEM) showed, the rat articular chondrocytes were clear, well formed and arranged tidy in the control group. The surface of articular cartilage was rough in 100 μg/kg group.Collagen fasciculi ruptured and stacked up in 200 μg/kg group. Presented a typical articular dryness phenomenon,the cartilage surface collapsed and many pits appeared in 300 μg/kg group. Transmission electronic microscope (TEM) showed that chondrocytes were abundant with cytoplasm, well-developed rough endoplasmic reticulum in the control group; agglomerate chromatin scattered along the karyotheca, nuclear membrane was thickening, with vacuolar degeneration of the endoplasmic reticulum in the 100 μg/kg group; endoplasmic reticulum expended, with protein retention and organelles breaks in the 200 μg/kg group. A large number of chondrocytes lost organdles, the membrane structures disrupted and the cartilage matrix stromatolyzed in the 300 μg/kg group. Conclusions Within the range of 100 - 300 μg/kg, T-2 toxin induces dose-related articular cartilage injury, the greater the dose, the more serious damage.

Objective To investigate the biological function of NS5ABP37 and to look for proteins interacting with NS5ABP37 protein in hepatocytes. Methods We constructed bait plasmid expressing NS5ABP37 protein of hepatitis C virus (HCV) by cloning the gene of NS5ABP37 protein into pGBKT7, then the recombinant plasmid DNA was transformed into yeast AH109 (α type). The transformed yeast AH109 was mated with yeast Y187 (α type) containing liver cDNA library plasmid in 2×YPDA medium. Diploid yeast was plated on synthetic dropout nutrient medium (SD/-Trp-Leu-His-Ade) containing X-α-gal for selection and screening. After extracting and sequencing of plasmids from positive (blue) colonies, we made a sequence analysis by bioinformatics. Results We screened twenty-five proteins binding to NS5ABP37, including Homo sapiens cyclin Ⅰ (CCNI) gene, Homo sapiens matrix metallopeptidase 25 (MMP25) and Homo sapiens talin 1. Conclusion The yeast-two hybrid system is an effective method for identifying hepatocyte proteins interacting with NS5ABP37 of HCV. And the biological function of NS5ABP37 may be associated with glycometabolism, lipid metabolism and apoptosis.

Objective To compare the early renal function recovery after kidney transplant from donation after cardiac death (DCD) and brain death (DBD).Methods The Medline (1950-2011),Embase and Cochrane library database were searched and supplemented by review of conference proceedings and publication bibliographies.All original single institution studies reporting outcomes for DCD and DBD kidney transplant recipients were considered.Odds ratios (OR) and 95％ confidence intervals (CI) based on random effects models were calculated.Results Nine publications,all cohort studies,involving 2049 DCD and 5498 DBD recipients,were included.DCD recipients had 7.24 times increased odds of DGF (OR=7.24,95％ CI =3.86-13.58),and 4.97 times increased odds of PNF (95％ CI =3.77-6.55).Conclusion DCD renal transplantation is associated with higher risks of DGF and PNF.

Objective To investigate the effect of noninvasive ventilator therapy on serum C-reactive protein (CRP), endothelin-1 (ET-1) and tumor necrosis factor-α (TNF-α) levels in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and its clinical significance. Methods One hundred cases of moder-ate and severe OSAHS patients were selected by the method of parallel opening. All of the patients were given health education requirement , quitting smoking and wine , low fat diet and exercise to lose weight and other con-ventional treatment. The patients were randomly divided into the treatment group of 42 cases with noninvasive ventilator treatment , 44 cases treated with conventional treatment , to observe the changes of serum CRP , ET-1 and TNF-α levels and PSG parameters after 12 weeks in two groups. Results Apnea hypopnea index (AHI), oxygen desaturation index (ODI), the lowest oxygen saturation (LSpO2), and the average oxygen saturation MSpO2 in OSAHS patients were significantly improved after treatment (P < 0.01), but the degree of improvement in the two groups after treatment was significantly higher than the control group (P < 0.01). Plasma CRP, ET-1 and TNF-α levels in the two groups after treatment were lower than before treatment (P < 0.05 or P < 0.01), but the treatment group was significantly higher than that of the control group ( P < 0 . 05 or P < 0 . 01 ) . Conclusion Noninvasive ventilator therapy in improving the OSAHS monitoring data of patients with PSG can effectively reduce the serum CRP, TNF-α, ET-1 level, reduce the body′s inflammatory reaction.
