AIM: To investigate the effect of binocular vision training on stereopsis establish and visual function in child concomitant strabismus after surgery
METHODS:Ninety-three cases of strabismus children were randomly divided into two groups, making it comparable. The control group (n=46) were treated with conventional surgery and care;the observation group ( n=47) on the basis of routine care as control group, were given binocular vision training. Synoptophore and Titmus stereoscopic view were used to check the function of stereoscopic.
RESULTS:After treatment, simultaneous perception, visual fusion and stereopsis of trail patient were 77%, 62% and 40%, respectively, those of control group were 48%, 35% and 18%, the difference was statistically significant (P<0. 05). After treatment, fovea stereopsis and macular stereopsis children in observation group were accounted for 32% and 26%, respectively, in the control group those were accounted for 18% and 11%, respectively. Those in the observation group were significantly more than the control group. No stereoscopic patients in observation group were 23%, and that was 54% in the control group. That in the observation group was significantly less than the control group. The difference comparison between the two groups was statistically significant (P<0. 05).
CONCLUSION: Binocular vision training can effectively help children to build concomitant strabismus after surgery, for children with strabismus should be treated with conventional visual training to improve visual function and improve the life quality.

Objective To investigate the induction of specific anti-tumor immune response by transfected dendritic cells (DCs) with survivin mRNA of human pancreatic cancer, and to provide the experimental evidences for the treatment of human pancreatic cancer with DCs vaccine. Methods DCs were isolated and cultured from peripheral blood mononuclear cells (PBMCs). After being transcripted and amplified, survivin mRNA was transfected into DCs by electroporation. The expression of survivin in DCs at different time points was detected by quantitative real-time PCR. The survival rate of DCs before and after transfection was determined by MTT method. The induction of specific cytotoxic T lymphocyte (CTL) response by survivin mRNA transfected DCs was measured by 51Cr standard cytotoxicity test. The induction of specific CTL activation by survivin mRNA transfected DCs was evaluated through testing released IFN-γ by ELISA method. Results After survivin mRNA transfection for 48h, the expression of survivin mRNA in DCs reached the highest point (46.09±6.57). After transfection, the survival rate of DCs was stabilized around 80%. The DCs transfected with survivin mRNA could effectively induce HLA-A2+ / survivin+ specific CTL immune responses. Stimulated with pancreatic cancer cell line Capan-2 cells or SCL-1 cells as control group, the IFN-γ released in 24 hours by survivin specific CTL were (28.79±5.70) U/ml and (25.12±2.13) U/ml respectively, there was no significant difference (P=0.761). Conclusion The induction of CTLs by DCs transfected with human pancreatic cancer survivin mRNA could produce specific anti-tumor immunity.

Objective To investigate the best method of transfecting total RNA extracted from pancreatic cancer MiaPaCa-2 cells into dendrtic cells (DCs). Methods DCs were cultured from peripheral blood mononuclear cells induced by rhGM-CSF, rhIL-4 and TNF-α. Morphology of DCs was observed. Flow cytometry was used to detect the mature DCs specific surface markers:CD40, HLA-DR, CD83, CD86. Mixed lymphocyte (MLR) was used to determine the ability of DCs to stimulate allogeneic T cell proliferation.Liposomal transfection, electroporation method and passive transfection was used to transfect MiaPaCa-2 cell total RNA into DCs, Real time RT-PCR and MTT assay was used to determine the expression of MUC1 mRNA and the survival rate of the RNA transfected DCs. Results The cells acquired showed typical DCs morphology, the positive rate of CD40, HLA DR, CD83 and CD86 were 34.3% ,50.2% ,89.2% and 73.6%,and they showed a strong ability to stimulate allogeneic T cell proliferation. 48 h after transfection with MiaPaCa-2 cells total RNA by using electroporation, the MUC1 mRNA amount (45.39 ± 9.33) in DCs was higher than that of liposomes method (3 1. 68 ± 7.25) and passive transfection method (18.53 ± 3.26) . DCs survival rate was (80.36 ± 2.43)% by using electroporation, which was relatively lower than (91.48 ±5.42) % by using passive transfection method, but higher than (67.44 ± 2.51) % by using liposomes method,and it was stabilized around 80%. Conclusions Transfecting total RNA extracted from pancreatic cancer MiaPaCa-2 cells into DCs with electroporation is efficient and safe.

BACKGROUND:Our previous studies have shown that mesenchymal stem cells play an immunomodulatory role in Th17 cells, but the mechanism of action remains to be elucidated, therefore, to explore the role of Tol-like receptor 1 in which wil provide possible experimental basis for the future potential of celltherapy strategies.
OBJECTIVE:To investigate the role of Tol-like receptor 1 in the immunoregulatory function of mesenchymal stem cells on Th17 cells.
METHODS:Separation of adherent bone marrow-derived human embryonic sources of mesenchymal stem cells, immunomagnetic separation of normal CD4+T cells. CD4+T cells were cultured alone or in combination with mesenchymal stem cells co-cultured 4d. Real-time quantitative polymerase chain reaction assay interleukin-17, Tol-like receptor 1 expression levels related genes;number of Th17 cells by flow cytometry. Bone marrow mesenchymal stem cells from human embryos were separated using adherence method, and co-cultured with human CD4+T cells from healthy donors using immunomagnetic separation method for 4 days. The expression of interleukin-17 and Tol-like receptor 1 mRNA was detected by real-time PCR, and the number of Th17 cells was observed by flow cytometry.
RESULTS AND CONCLUSION:Tol-like receptor 1 mRNA was expressed in both CD4+T cells and mesenchymal stem cells. Level of interleukin-17 mRNA was significantly higher in mesenchymal stem cells co-cultured with CD4+T cells than in CD4+T cells cultured alone (relative value 3.59±0.11 vs. 1.14±0.08, P<0.01). Consistent with the expression of interleukin-17 mRNA, increased level of Tol-like receptor 1 mRNA was detected in mesenchymal stem cells co-cultured with CD4+T cells compared with CD4+T cells cultured alone (relative value 6.07±1.79 vs. 1.53±0.63, P<0.01). Furthermore, Flow cytometry analysis showed that the percentage of Th17 cells in the mesenchymal stem cells co-cultured with CD4+T cells was significantly higher than that in CD4+T cells cultured alone, (4.53±1.27)%vs. (2.39±0.80)%(P<0.01). Tol-like receptor 1 might be involved in the immunoregulatory regulation of Th17 cells by mesenchymal stem cells.

Objective To investigate the clinical efifcacy of Tiotropium Bromide inhaler on patients with stable chronic obstructive pulmonary disease(COPD). Methods 134 cases with stable COPD were equally randomized into three groups. The conventional treatment group(n=46) were 40 male and 6 femal, aged (63.20±9.3)years old and treated with sustained-release theophylline 0.1 g orally. Observation group with 18μg Tiotropium Bromide(n=45) were 40 male and 5 femal, aged (63.4±85)years old, and given inhaled Tiotropium Bromide 18μg. Observation group with 32μg Tiotropium Bromide(n=43) were 39 male and 4 femal, aged (63.2±9.0)years old, and given inhaled Tiotropium Bromide 32 μg. All patients received same routine therapy, and lasted for 4 weeks. improvement Pre-and post-treatment Lung function and quality of life were compared among those groups. Results In observation group, the results of St George respiratory questionnaire decreased signiifcantly after treatment, which was signiifcantly lower than those of the routine-treatment group (P<0.05). FEV 1/FVC, FEV 1/Pred, FEV 1 were signiifcantly higher than those before treatment (P<0.05). However, the control group showed no signiifcant difference. Conclusion Inhaled Tiotropium Bromide can improve lung function and life quality of paitents with stable COPD, the dose with 32μg per day, which was signiifcantly lower than 18μg per day.
