Geometrically virtual models of three-dimensional blood flow field and eight types of mesh stent (different porosity and different stent shape) were constructed using SoildWorks software, and simulation of stented models were performed respectively using finite element software ANSYS11.0 according to computation fluid dynamics method. The flow resistance of the semi-circular section stent model of blood flow from the semi-circular planar surface was greater than the reverse in a certain range of permeability. However, the result was the opposite when the porosity increased to a specific value. For both grid-stent model and sine-stent model, flow resistance of blood that flowed from the stent in both directions increased with the porosity reduction. Under the same porosity and the direction of blood flow from the same stent, the flow resistance of the grid stent model was 1.5 times greater than the sine-stent model. Results showed that there are different effects on the flow resistance in blood flow in different directions from the semi-circular section stent model.

The ubiquitin-like modifier bISG15 is an antiviral protein found in fetal bovine lung (FBL) cells.Bovine Herpesvirus 1(BHV-1),which is a viral pathogen of cattle,can infect FBL cells and induce cytopathic effects.Real-time PCR assays showed that BHV- 1 's infection could repress the basal or inducible transcription of bISG15 in FBL cells.It demonstrates that this repression effect depends on BHV-1 viral infection and new protein synthesis.Our previous work showed that bIRF-3 was the key factor in the stimulation of bISG 15 in FBL cells,so the effect of BHV-1 viral protein on bIRF-3 activating the promoter of bISG15 was confirmed.The luciferase assay showed the BHV-1 viral protein bICP0 inhibited the activation of bISG15 promoter stimulated by bIRF-3.Taken together,our work suggested that BHV-I had some molecular mechanism to resist the cellular bISG15'santiviral functions.

BACKGROUND:Sodium hyaluronate is a polysaccharide polymer biomaterial, which is considered to have a certain effect to repair the cartilage surface, reduce the release of inflammatory mediators, and promote meniscal repair. OBJECTIVE:To observe the therapeutic effect of Fast-Fix combined with sodium hyaluronate in meniscal repair under arthroscope. METHODS:Eighty-six patients with meniscus injury admitted at the Department of Orthopedics, CNPC Central Hospital, from March 2008 to March 2014 were enrol ed in the study. The average age was 25.5 years, and the average duration of disease was 1.5 months. The main clinical manifestations included knee joint pain and swel ing after exercise and positive McMurray signs. The MRI results showed meniscus tear or degeneration. Arthroscopic repairing surgeries were performed with Fast-Fix combined with sodium hyaluronate injection (2.5 mL at the end of surgery), and then sodium hyaluronate was injected intraarticularly at 1, 2, 3 weeks after surgery. Each patient was assessed with Lysholm knee joint score system before and after operation. RESULTS AND CONCLUSION:Eighty-one patients were fol owed up for an average of 1.5 years and five patients were lost to fol ow-up. Joint locking, significant tenderness and movement disorder symptoms disappeared in 79 of 81 patients, and meniscal healing was shown on MRI review within 1 year after surgery;the Lysholm score was higher than 75 points, and the excel ent rate was 98%. Only the remained two patients felt swel ing and tenderness and the movement was slightly restricted when going down or standing up. The Fast-Fix combined with sodium hyaluronate in meniscal repair under arthroscope has good effect and good function of knee joint.
