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.

BACKGROUND:Previous studies have found that embryonic bone marrow mesenchymal stem cel s can promote human Th17 cel proliferation, but the inherent regulatory mechanisms stil need to be elucidated. OBJECTIVE:To investigate the role of Tol-like receptor 3 in the immunoregulation of Th17 cel s by mesenchymal stem cel s.
METHODS:Human CD4+T cel s from healthy donors were isolated by immunomagnetic bead method, and then cultured alone or co-cultured with embryonic bone marrow mesenchymal stem cel s for 4 days. The mRNA expression level of interleukin-17, Tol-like receptor 3 and MyD88 was detected by real-time PCR.
RESULTS AND CONCLUSION:Compared with CD4+T cel cultured alone group, the mRNA level of interleukin-17 was significantly higher in the co-culture group (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 3 mRNA was detected in the co-culture group compared with the CD4+T cel cultured alone group (3.10±1.60 vs. 0.94± 0.01, P<0.05). Furthermore, MyD88 in the co-culture group was significantly higher than that in CD4+T cel cultured alone group (2.29±0.05 vs. 1.85±0.31, P<0.01). Tol-like receptor 3 may be involved in the immunoregulation of Th17 cel s by embryonic bone marrow mesenchymal stem cel s, which provides experimental evidence for potential cel therapeutic strategy.

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.

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.

Percutaneous mechanical circulatory support (PMCS) devices are effective in the treatment of patients with cardiogenic shock and acute decompensated heart failure, as a bridge to the recovery of heart function or further treatment. The intra-aortic balloon pump (IABP) is now the most widely used PMCS. New PMCS devices including Transseptal device of Tandem-Heart, transaortic valve device of Impella and extracorporeal membrane oxygenation (ECMO) might provide more effective hemodynamic supports. Doctors should choose appropriate PMCS devices and their working modes, according to patient's clinical conditions, based on the working principles and hemodynamic effects of the devices, in order to achieve the best effects and help patients live through the crisis of diseases.

Ebola virus, the cause of severe and fatal hemorrahagic fever in humans, belongs to filovirus family. This study was designed to establish a cell-based screening and evaluation system in the pharmacological study of antivirus compounds. Three reporter systems were established with recombinant pseudoviral luciferase of HIV core (pNL4-3.Luc.R(-)E(-)) packed with filovirus glycoprotein (EBOV-Zaire GP/HIV-luc, EBOV-Sudan GP/HIV-luc and Marburg GP/HIV-luc), which are required for virus entry of cells. The level of filovirus entry was determined by the expression of luciferase reporter gene in the infected cells. For screening of filovirus entry inhibitors, the vesicular stomatitis G packed pseudovirions (VSVG/HIV-luc) was used to determine the compound specificity. The results of known filovirus entry inhibitors demonstrated successful establishment of the new model systems, which would be useful in high throughput screening of anti-filovirus drugs in the future.
