Objective To assess the effect of IL 1Ra gene transfer on amelioration of symptoms and cartilage injury of osteoarthritis (OA) in rabbit. Methods Thirty New Zealand rabbits were divided into 3 groups. Synovial membrane was harvested from the left knee, and synovial fibroblasts were isolated and cultured. Fibroblasts from each rabbit were traanfected using the retrovirus with either IL 1Ra gene (group 3) or marker gene (group 2) in vitro . OA was induced in the right knee of all rabbits by anterior cruciate ligament transection (ACLT). The autologous cells tranfected with IL 1Ra gene or marker gene were respectively injected into the right knee of group 3 and 2. At the end of 2nd and 4th week, IL 1Ra level in synonival fluid (SF) of the right knee were determined by ELISA. The results were evaluated by grading local pain stimulating response, change of gait, joint swelling, and range of joint motion. The degree of injury to the cartilage was graded by the staining of India ink and pathological examination. Results The IL 1Ra level in the right knee SF of group 3 were 20 16?1 8 ng/ml and 4 82?0 52 ng/ml at the end of 2 and 4 weeks after gene delivery, respectively, while that in the group 2 and group 1 was very low. In IL 1Ra gene transfection group, the symptoms of the joint injury and the degree of cartilage lesion were less severe compared with control group. Conclusion This study showed that IL Ra transfer could raise IL 1Ra level in knee joints, thereby alleviate the symptoms and cartilage injury in experimental osteoarthritis

To explore the effects of artisense IRAK-2 oligonucleotide on the prostacyclin (PGI2) synthesis in human umbilicalvein endothelial cells (HUVEC) induced by interleukin-1 (IL-1) and tumor necrosis factor (TNF).Methods:The HUVECs were transfectedwith antisense interleulkin-1 receptor associated kinase-2 oligonucleotide (IRAK-20DN) and stimulated with IL-1 and TNF. The levels of PGI2release were analyzed by competitive ELISA. Results: Pre-transfection with antisense IRAK-20DN could remarkably decrease the levels ofPGI2 synthesis induced by IL-1 in time- and dose-dependent manner, whereas it could not attenuate the one stimulated by TNF. Conclusion:The response of antisense IRAK-2 ODN to IL-1 and TNF-stimulated PGI2 release were different. IRAK-2 plays a key role in the IL-1 signalingevents leading to PGI2 release.

BACKGROUND: Electrostatic layer-by-layer (LbL) self-assembly is a simple, effective and novel approach to carrying macromolecules into microcapsule carriers.OBJECTIVE: To prepare chitosan (CS) microcapsules to control the releasing of heparin (Hep) by LbL.METHODS: CS microspheres were fabricated by a sodium sulfate-based precipitation process and then used as positively charged templates for polyelectrolyte multilayer coatings to carry heparin by the LbL self-assembly technique. The polycation was CS and the polyanion was Hep. The microcapsule was formed via coating {CS/Hep}3 on CS hydrogel template. The microcapsules composed of {CS/ Hep}3 on CS hydrogel templates were confirmed by fluorescence inverted microscopy, confocal laser scanning microscopy and laser particle size analysis. The assembly of polyelectrolyte layers on CS hydrogel microspheres was monitored by Zeta Potential Analyzer.RESULTS AND CONCLUSION: The resulting microcapsules were about 1 μm in average diameter, and allowed spontaneous loading of heparin through electrostatic interaction, with the encapsulation efficiency and carrying capacity of 83.8% and 3.05%, respectively.

Objective To investigate two techniques and outcome in repairing facial concave deficits.Methods Eleven patients with facial concave deformity were included in this study:nine were treated with autologous fat granule injection,1,3 and 5 patients were given fat granules injection fourth,twice and once,respectivly.The other 2 patients were repaired with homolateral temporal fascia flap.Results The implantation by using autologous fat granules in all 9 patients showed excellent results.Homolateral temporal fascia flaps were used in 2 cases,one of which was formed hematoma after operation and scavenged thereafter.All the patients had satisfactory results.Conclusion Both approaches well rehabilitate patients' facial contour,and thus are capable of repairing moderate or minimal facial concave deficit and worth recommendation.

Objective To compare the clinical effect of radionuclide myocardial perfusion imaging(SPECT)and multilayer spiral CT coronary artery imaging(MSCT) in the diagnosis of coronsry artery disease(CHD).Methods The clinical data of 36 patients suspected with CHD and routine inspection of SPECT and MSCT were retrospectively analyzed.The diagnostic effects of two methods were compared.Results The sensitivity,specificity and the rate of accuracy of SPECT was 89.47％,94.12％,and 91.67％,respectively,while the sensitivity,specificity and the rate of accuracy of MSCT was 84.21％,94.12％,and 88.89％,respectively.There were no obvious difference in two groups (x2 =1.265,1.668,2.005,1.526,1.889,all P ＞ 0.05 ).Conclusion There was a high degree consistency on the diagnosis of CHD between SPECT and MSCT.In the application,combined with the two methods could improve the diagnosis of CHD.
