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.

AIM To study the protective effect of TFA against cerebral ischemia reperfusion injury. METHORDS The cerebral ischemia model in mice was made by means of ligating bilalateral common carotid arteries.The mice survive rate during 6 h was observed,and malondialdehyde (MDA) in the ischemic cerebral cortex was measured. Using nitrogen anoxia model in mice,the survive time was observed. Ligating bilateral common carotid arteries and descending blood pressure,the cerebral ischemia reperfusion model in rabbits was established. The brain of rabbits was initiated by ischemia for 60 min followed by 30 min of reperfusion. The electroencephalogra phy (EEG) of cerebral ischemia and reperfusion was recorded. Malondialdehyde(MDA) and lactate dehydrogenase(LDH) in the ischemic cerebral cortex were measured. RESULTS TFA(30,60,120 mg?kg -1 ) prolonged the survive time after anoxia in mice,enchanced the survive rate after cerebral ischemia and inhibited the increasing of MDA contents in the cerebral cortex in mice.TFA(12,24,48 mg?kg -1 ) inhibitid the changes of EEG,MDA and LDH induced by cerebral ischemia reperfusion in rabbits. CONCLUSION TFA has protective effects on cerebral ischemia reperfusion injury,the mechanism may relate to attenuating free radical and lipid peroxidation.

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.

Objective To investigate the role of mifepristone in endometriosis after laparoscopic surgery. Methods One hundred and forty-three women diagnosed with endometriosis after laparoscopic surgery were divided into two groups: one group with 78 cases were given mifepristone at 10 mg once daily (mifepristone group),and the other group with 65 cases were given gestrinone at 2.5 mg,twice every week (gestrinone group). All patients were followed-up 1 to 2 years and observed curative effect, compared the therapy effect on endometriosis as well as the side effects of two drugs. Results The clinical symptom and sign were improved at 3, 6, 12 months in two groups (P< 0.01). The rate of efficiency was 85.9%(67/78) in mifepristone group,and 84.6%(55/65) in gestrinone group, there was no significant difference between two groups (P > 0.05). The rates of acne, weight gain, joint ache, aminotransferase increase was lower in mifepristone group than those in gestrinone group (P <0.01 or <0.05). The recovery time of ovulation or menstruation was shorter in mifepristone group [(12.0 ± 2.9), (26.8 ± 3.9) d]than those in gestrinone group [(25.3 ±3.7), (35.0±4.1) d](P<0.05). Conclusions Mifepristone seems to be an effective,safe,and convenient treatment for endometriosis with low-cost and few side effects. Therefore,it can be used as first choice for treatment of endometriosis after laparoscopic surgery.
