Objective To investigate the effect of rivaroxaban on prevention from deep venous thrombosis after hip replacement surgery .Methods 80 patients with lower limb parallel arthroplasty were randomly divided into observation group and control group from January 2014 to January 2015.40 cases in each group.Control group was given aspirin treatment, observation group was given rivaroxaban treatment, indicators changes were followed up and recorded.Results PT, APTT values of observation group one week after treatment were (35.79 ±2.16),(15.84 ±2.11) s, which were better than control group (45.64 ±2.12),(18.72 ±2.02) s (P<0.05).TT, D-dimer of observation group(13.48 ±2.10)s,(2.34 ±0.33)g/L after a week were better,than control group (16.38 ±1.79)s, (1.42 ±0.21)g/L (P<0.05) respectively.Conclusion Effect of rivaroxaban in prevent deep venous thrombosis after hip replacement surgery is exact without obvious adverses reaction, it is worthy of further research and application.

Objective To prepare monoclonal antibody(mAb) against CUE domain containing 2(CUEDC2) protein and detect the expression level of CUEDC2 in mouse tissues.Methods Fusion protein GST-human CUEDC2(hCUEDC2) was expressed and purified,and mAb against CUEDC2 was prepared by using hybridoma technique.The specificity of the antibody and CUEDC2 expression in mouse tissues were detected by Western blot analysis.Results We obtained mAb against CUEDC2 protein,which recognized specifically both hCUEDC2 and mouse CUEDC2.The mAb could be used to detect expression level of CUEDC2 protein,which was different in various mouse tissues.Conclusion The prepared CUEDC2 has good mAb specificity and can be used to detect expression of CUEDC2 protein in mouse tissue,thus providing a useful tool for further investigation into the functions of CUEDC2.
