Objective To study the effect of binocular vision function training for fusion in the eye position and three levels of eye function in adult patients after concomitant strabismus surgery. Methods 56 cases with postoperative concomitant strabismus were randomly divided into training group and control group . In the training group, patients were trained with software to enhance the fusion. After training for 7, 30, 180 and 365 days, the eye position, the fusion and the stereoesthesia were observed and analyzed. Results After training for 365 days, the deteriorative ratio in the training group is 3%, which is significantly lower than control group (23%)(P<0.05). The correction ratio in eye position is 20%, which is significantly higher than control group (4%)(P<0.05). The recovery ratio in binocular vision function is 53%, which is significantly higher than control group (15%)(P<0.05). The recovery ratio in stereaeuity is 46%, which is significantly higher than control group (11%)(P<0.05). Conclusions Fusion training can enhance the recovery of fusion and stereaeuity, decrease the deteriorative ratio, and correct the eye position after surgery in concomitant strabismus patients.

Objective:To investigate the difference of biological characteristics and responses to PDGF-BB between human ovarian carcinoma-derived microvascular endothelial cells and human umbilical vein endothelial cells.Methods:The ovarian carcinoma-derived microvascular endothelial cells were isolated and purifed from ovarian carcinoma tissues.Compared to the human umbilical vein endothelial cells,the biological characteristics and responses to PDGF-BB were observed in OdMEC for the changes of growth,PCNA and VEGF expression.Results:20ng/ml PDGF-BB could enhance both kinds of endothelial cells to proliferate,express PCNA and VEGF.The proliferation and PCNA protein expression in HUVEC were augmented more significantly than those in OdMEC,the protein and mRNA of VEGF expression were augmented more significantly than those in HUVEC.Conclusion:The responses of OdMEC to PDGF-BB were significantly different from those of HUVEC,which provides experiment basis for research on ovarian carcinoma vascularization and antiangiogenesis therapy.

The paper introduces using MedlineR to carry out data mining from Medline, for observing the gene relation, and using Pajek to realize the visualization of the results. Practice proofs that MedlineR could help researchers come up with assumptions in the field that they are interested in, and get a visual fingerprint. These results are the bases to go to more complex literature data mining and an important supplementary to experimental methods.

Objective To investigate the influence of surface grafting density of polyethylene glycol (PEG) molecules on the interactions of nanoparticle with the biomembrane.Methods The dynamics of polymer as well as its shielding effect on the wrap of the membrane were investigated using coarse-grained (CG) molecular dynamics simulations.A coarse grained model force field,MARTINI,was employed for its ability to reproduce experimental properties of various lipid dynamics and some kinds of polymer as well.Results As a result,structural variations and energy changes of grafted PEG molecules on the nanoparticles,adsorbing dynamics of PEGs on the membrane as well as the wrap rates of the membrane were obtained to shed light on the PEGylation-mediated shielding mechanism in the adsorption of PEGylated nanoparticles on the membrane.Conclusions The surface grafting density of PEGylated nanoparicles has been found to play a crucial role in the stealth shielding behavior of PEGylated nanocarriers.These studies are consistent with experimental observations and to some extent give a molecular level interpretation of the macroscale observations of prolonged circulation half-life of stealth nanocarriers.

For a valid control of the finance management, the management system is developed again aiming at finance related control links and key control points. In this way, the control is rigorous and integral with simple procedures for check and examination. The key control point is set oriented to note management. Real-time operation is controlled. Post output processing is controlled. With business income and business expenditure as the main line, the control process of the related links are built up. Computer maintenance system is controlled.

BACKGROUND:The molecule mechanism underlying endothelial progenitor cells(EPCs) differentiation into mature endothelial cells remains poorly understood.It requires for the regulation of the expression of various genes inside cells by various signal pathways,PI3K/Akt maybe included.OBJECTIVE:To investigate the role of PI3K/Akt in EPCs differentiation.DESIGN,TIME AND SETTING:A group control in vitro experiment was performed at the Pathology Laboratory in Shengjing Hospital of China Medical University from September 2007 to March 2008.MATERIALS:Wistar rats aged 4-6 weeks,of either gender.METHODS:EPCs were isolated from rat bone marrow with density gradient centrifugation.Then difference-speed adherence screening method was used to obtain the second time adherent cells,which then were inoculated in culture flask.After 5 days of culture,cells were collected to be indentified with laser confocal microscopy.The differentiating EPCs were those that have positive results of both AC133 and vWF stainings.MAIN OUTCOME MEASURES:The mRNA and the protein expression of AC133,vWF,PI3K and Akt in EPCs were detected with Western blot and reverse transcription-polymerase chain reaction(RT-PCR) after 0,3,7,10 and 14 days of inoculation respectively.RESULTS:According to the RT-PCR and Western blot detection,AC133 showed the strongest expression at day 0,the weaker at day 3 and none at day 7,10 and 14(P

The accessibility of drugs is the fundamental condition for achieving the universal health care, and price is the important factor of accessibility.It is essential to have a national price negotiations mechanism for the patented drugs and for exclusive production of drugs.As for the regular works, the national price negotiations mechanism should be ruled by law, while rules and regulations should be formulated accordingly.This paper discusses the specific content and the clarification of the legislative principle of legal framework for the negotiations, main roles, and selection of objects, procedure, results and application of the negotiations.It also analyses the existing problems are analyzed, and put forward the future legislation and corresponding rules.
