[Objective]To study the clinical result of Endo-Model rotating-hinge prosthesis in the treatment of severe knee deformity. [Method]Twenty-two patients(10 males and 12 females;12 right knees,8 left knees,and 2 bilateral knees) were selected for total knee arthorplasty using Endo-Model rotating-hinge prosthesis.The average age was 56.2 years.All the patients were evaluated by HSS score system.[Result]All incisions healed at one-stage and all malformations were corrected.The functional result was good.Mile deep vein thrombosis was found in one case after operation.All the patients were followed up for 6-55 months.No infection or prosthetic loosening was developed.[Conclusion]Endo-Model rotating-hinge prosthesis is an effective and reliable prosthesis for severe knee deformity.

Objective To evaluate the therapeutic efficacy of agitating thrombolysis technique for Budd-Chiari syndrome complicated with inferior vena cava (IVC) fresh thrombus. Methods From August 2004 to March 2009, 5 patients of Budd-Chiari syndrome (four males and one female, aged 36-48 years) with IVC fresh thrombus were treated with agitating thrombolysis technique. After anpography of IVC the recanalization of IVC was performed, which was followed by agitating thrombolytic therapy. Finally,IVC was dilated with percutaneous transluminal balloon angioplasty. Clinical follow-up of IVC patency was conducted by color Doppler sonography. Results After agitating thrombolysis. The thrombi were completely disappeared in all 5 patients without single occurrence of pulmonary embolism. In all patients, IVC remained patency on color Doppler ultrasonograph after following up for a mean period of 23.8 months. Conclusion Agitating thrombolysis technique is a safe and effective treatment for Budd-Chiari syndrome complicated with IVC fresh thrombus.

Objective Posterior reversible encephalopathy syndrome (PRES) is a rapidly evolving neurologic syndrome with characteristic clinical and radiographic features. To define the clinical characteristics of PRES in patients with eoneomitant systemic lupus erythematosus (SLE) by analyzing their clinical manif-estations and reviewing the literature. Methods The details of 4 cases and a review of the literature relevant to the development of PRES in association with SLE are presented. We described the clinical and imaging characteristics and associated risk factors of posterior roversible PRES in patients with SLE. Results Inclu-ding our cases, we reviewed a total of 48 patients with SLE and PRES. Hypertension was observed in 42 cases (88%), renal failure in 30 cases (63%), 39 recent onset cases were treated with immunosuppressive drugs and/or steroids recently (81%). Headache was observed in 46 cases (96%), Corffusion/coma in 20 cases (42%), seizures in 43 cases (90%), visual disturbances in 28 cases (58%). Neuroimaging demonstrated posterior white matter edema involving the parietal-occipital, temporal, frontal lobes, and cerebellum. The hypertension and other worsening factors should be treated. Conclusion PRES is a central nervous system syndrome that is observed in SLE patients. It is associated mainly to acute hypertension, renal failure, and immunosuppressive drugs. Although reversibility is common, residual neurological damage may be observed. Complete clinical and radiographic recovery oeeurrs with prompt antihypertensive treatment and supportive care.

Objective To isolate and purify pancreatic ductal epithelial cells in adult rats,and induce differentiation of pancreatic ductal epithelial cells to islets in vitro.Methods By retrograde in- jection of collagenase into biliary-pancreatic tract,pancreatic tissues were digested and different types of pancreatic cells including islets,duct and degranulated aicni cells were separated by means of density gradient centrifugation.Ductal cells were purified by adhering method and identified by immunocyto- chemistry stain of ductal epithelial cells maker antigen(Cytokeratin 19,CK-19).Ductal cells were ex- panded in RMPI 1640 with 10% FBS.About one week when most adherent ceils were of monolayer, the medium was changed to serum-free DMEM/F12 supplemented with keratinocyte growth factor (KGF)to further expand ductal epithelial cells.When ceils reached 80% confluence,nicotinamide and high concentration of glucose were added to promote differentiation of pancreatic ductal epithelial cells.Islets like-structure was stained by Dithizone.Results Irnmunocytochemistry stain of CK-19 re- vealed that most isolated ceils were ductal epithelial ceils.The cultured ductal epithelial cells began to adhere at day 1,reached 80% confluence and cell clones were formed at day 14-21.At day 28,islets- like-structure appeared and was positive for Dithizone staining.Conclusions Ductal epithelial cells of rats can be isolated by means of density gradient centrifugation and purified by adhering method.Duc- tal epithelial cells can differentiate into islets-like-structure in vitro.

0.1).One(1.3%) of them suffered from intracranial hemorrhage.Conclusions 1.(L-ASP) may affect the function of coagulation system,such as prolonged APTT and hypofibrinogenemia.2.There was no statistical difference in side effects of coagulation,in use of domestic L-ASP and foreign L-ASP,intravenous dosing and intramuscular dosing.

Objective To investigate the effect of fluvastatin on activation of nuclear factor kappa B (NF-κB)induced by angiotensin Ⅱ (Ang Ⅱ ) in rat kidney tubular epithelial cells (NRK-52E). Methods NRK-52E cells were divided into (1)control group ; (2)Ang Ⅱ groups with different concentration and time; (3)Ang Ⅱ (10-6 mol/L)+SB203580 ( 10 μmol/L)group; (4) Ang Ⅱ (10-6mol/L) +different fluvastatin concentration (10-7, 10-6, 10-5 mol/L)groups;(5)Ang Ⅱ (10-6mol/L) +fluvastatin (10-5 mol/L) +mevalonate (10-4 mol/L)groap. Electrophoretic mobility shift assays (EMSA) was used to detect NF-κB activation. Phosphorylation of cellular p38 mitogen-activated protein kinase (p38MAPK) was determined by Western blot. Monocyte chemoattractant protein (MCP)-1 mRNA was determined by RT-PCR. Results Ang Ⅱ stimulated the DNA-binding activity of NF-κB,phosphorylation of p38MAPK and up-regulated the expression of MCP-1mRNA in cultured NRK-52E cells in a dose-dependent manner (P<0.01). Ang Ⅱ (10-6 mol/L) induced a rapid (5 minutes) elevation of the p38MAPK phosphorylation. NF-κB DNA binding activity was increased at as early as 30 minutes(P<0.01), peaked at 2 hours after AngⅡ treatment (P<0.01). This stimulatory effect of Ang Ⅱ on NF-κB was blocked by SB203580 (a specific inhibitor of p38MAPK) (P<0.01). Incubation of cells with fluvastatin significantly inhibited the Ang Ⅱ-induced NF-κB activation and expression of MCP-1 mRNA in dose-dependent manner (P< 0.05). Exogenous mevalonate (10-4 mol/L) prevented the effect of fluvastatin on NF-κB activation (P <0.05). Conclusions Fluvastatin reduces Ang Ⅱ-induced NF-κB activation via the p38MAPK pathway in NRK-52E cells. Such effect of flurastatin is partly through blocked by mevalonate.

Follicle-stimulating hormone (FSH) is synthesized and secreted by the anterior pituitary, which binds to its receptors expressed on the membrane of Sertoli cells in the testis to bring about spermatogenesis. With the development of DNA sequencing technology, FSH SNPs rs10835638 and FSHR SNPs rs6165, rs6166, and rs1394205 were detected, which might directly affect the expression of FSH and activity of FSHR, resulting in male spermatogenic dysfunction. This review focuses on the relationship of FSH and FSHR gene polymorphisms with male infertility.
