Objective To observe the effect of febuxostat on IL-1β, TNF-αand COX-2 in gout patients.Methods 82 patients with gout in our hospital from August 2015 to August 2016 were divided into the groups of 40 mg/day of febuxostat and 80 mg/day of febuxostat randomly, 41 cases respectively.Select the same period in our hospital health examination of 41 cases.The levels of serum uric acid were measured before and after one week, two weeks and four weeks after treatment.Serum levels of IL-1β, TNF-αand IL-1βin serum were measured by enzyme-linked immunosorbent assay (ELISA) COX-2 levels.Results The levels of serum uric acid in the group of 40 mg/day vs 80 mg/day of febuxostat were (570.4 ±70.5) μmol/L and (572.8 ±71.2) μmol/L, significantly higher than the normal group (296.5 ±9.7) μmol/L (P<0.05), serum uric acid level decreased gradually with the time of administration, and the serum uric acid levels of the two dosages of fosobutamol at one,two,four weeks were significantly lower than before treatment (P<0.05), but not to below the normal level.The IL-1βof 40 mg/day and 80 mg/day of febuxostat was (40.5 ±6.8) pg/mL and (41.7 ±7.2) pg/mL, COX-2 were (15.5 ±1.7) pg/mL and (15.8 ±1.8) pg/mL respectively, significantly higher than the normal group (8.8 ± 1.7) pg/mL (P<0.05), The expression of IL-1βwas significantly decreased at the second week of IL-1βdecreasing as the time of IL-1βdecreased gradually (P<0.05); TNF-αin 40 mg/day group and 80 mg/day group was significantly lower than that before treatrment (P<0.05), but not to below the normal level.Conclusion Febuxostat can significantly reduce serum uric acid levels in patients with gout, and may reduce IL-1β, TNF-αand COX-2 and other cytokine levels.

Objective To evaluate the effectiveness and safety of transcatheter closure of membranous ventricular septal defect (MVSD) using Amplatzer membranous VSD occluder (AMVSO). Methods The patients, who were clinically diagnosed with VSD were recommended for further transthoracic echocardiographic assessment using multiple standard views. If there were left to right shunts across ventricular septum, the margin of defects to the aortic valve was more than 1mm and that to tricuspid valve was more than 3 mm. If there was an aneurysm, it should not interfere with the function of outlet of right ventricule. Finally, if the diameter of VSDs wasless than 14mm, catheter closure of VSDs was suggested in these patients. The patients, having residual shunt after surgical closure of VSD, were included. All procedures were performed under local or general anesthesia. Transthorac echocardiography and X ray were used continuously to monitor the procedure. Transthoracic echocardiography was performed immediately after the release of devices, 24 hours, and 3 months after the procedure, respectively.Results From June 2002 to March 2003, 32 consecutive patients (15 females), underwent transcatheter closure of MVSD. The mean diameters of VSDs measured by echocardiography was 5.1 mm (3～8 mm) and, while that by angiography was 4.4 mm (3～8 mm). The mean size of the occluder was 7.6 mm(4～12 mm). The successful rate of device implantation was 100% (32/32). The residual shunt immediately after the closure was 11.5%, whereas after 24 hours it was only 7.7%, which was not serious. After 3 months′ follow-up, only 3.8% trivial residual shunt existed. No death occurred during and after the procedure. Atrial tachycardia, ventricular tachycardia, and bundle (right and left bundle) branch block, which was considered to relate to catheter manipulation inside the chamber of ventricle, were common and transient. One aortic regurgitation and tricuspid insufficiency became severe after the procedure, but they were not serious. One patient developed III degree A-V block 24 hours after the procedure, and EKG became LBBB 3 days after the temporary pace making. Hemolysis was observed in one patient, and he recovered 7days after the medication therapy. Conclusion Transthoracic echocardiography was very much effective in catheter closure of MVSD. The asymmetric self-expanding nitinol double-disc Amplatzer device designed for the transcatheter closure of MVSD is implanted easily and stably. Due to low ratio of residual shunt and few serious complications, the Amplatzer device is a good choice for the transcatheter closure of MVSD.

Objective To discuss the hemodynamics and treatment of silent patent ductus arteriosus (PDA) Methods The heart catheterizations were performed in seven silent PDA patients Results The mean pulmonary artery pressure of seven patients was (16?2 4) mm?Hg The mean Qp/Qs was 1 08?0 02 The mean size of the left right shunt was (0 32?0 08) L/min The proportion of left right shunt size in pulmonary blood flow was 0 098?0 024 on average The mean PDA at its narrowest segment was (0 9?0 2) mm We performed neither surgery nor interventional treatment in all patients In 9 5 months follow up (clinical findings, electrocardiography, echocardiography), no atrioventricular chambers enlargement, pulmonary hypertension, infective endoarteritis and infective endocarditis happened Conclusion In silent PDA patients, there is less size of left right shunt and smaller effect on hemodynamics Its treatment with surgical and interventional closure is under discussion

Objective To investigate the isolation and antimicrobial resistance of hypermutable Pseudomonas aeruginosa strains.Methods The cultured bacteria were identified by API 20NE system.The susceptibilities of bacteria were detected by disk diffusion method and the results were confirmed with the rules of NCCLS/CLSI.The hypermutable strains were identified byhigh concentration of rifampin-resistant growth assay.Results Among analyzed 100 strains,37 strains(37.0%) were hypermutable.The resistant rates of hypermutable strains to imipenem,meropenem,cefoperazone/sulbactam,piperacillin/tazobactam,ceftazidime,cephfime,aztreonam,amikacin and ciprofloxacin were significantly higher than those of non-hypermutable strains.The multidrug resistance rates of hypermutable strains were also higher than those of non-hypermutable strains.Conclusion The hypermutable strains of Pseudomonas aeruginosa sourced from chronic respiratory tract infections dominantly.The hypermutable strains were hyper-resistant and multidrug resistant to many antibiotics,so strengthened monitoring should be encouraged to control the prevalence of hypermutable Pseudomonas aeruginosa strains.
