Objective To investigate complications in patients after noncardiac thoracotomy in hypothyroidism with ST changes. Methods Sixty one patients with hypothyroidism undergoing noncardiac thoracotomy were divided into ST segment change group(28 patients having ST segment depression≥0.05 mV) and controls(33 patients) according to the results of Holter. All patients were added with thyroid hormone, until the function of thyroid gland was normal before thoracotomy. The myocardial ischemia was measured by Holter within 48 hours after thoracotomy. Serum thyroid hormones was examined by radioimmunoassay during, before and after thoracotomy. And cardiovascular events were foliowed-up to hospital. Results Before and after thoracotomy serum TT3 in ST segment change group was (1.30±0.41), (2.09±0.45)nmol/L, TT4 was (80.56±30.28), (84.55±33.57) nmol/L, respectively; compared with the control group[TT3: (1.43±0.52), (2.38±0.51)nmol/L, TT4:(82.70± 29.43), (93.47±35.02)nmol/L], no significant differences were found(all P>0.05). After thoracotomy, 24 patients occurred myocardial ischemia, 10 patients occurred cardiovascular events in ST segment change group; 8 patients occurred myocardial ischemia, a patient occurred cardiovascular events in control group, there were significant differences between two groups(χ2=22.95,10.95, all P<0.05). The positive predictive value of ST segment change in Holter detection was 36% (10/28) recording in cardiovascular events of patients with cardiovascular disease undergoing noncardiac thoracotomy and hypothyroidism, negative predictive value was 97%(32/33). Conclusions Myocardial ischemia and other cardiovascular events tend to occur in hypothyroidism patients with ST segment change after noncardiac thoracotomy. ST segment change of preoperative Hoher detection recording cardiovascular events of hypothyroidism patients undergoing noncardiac thoracotomy has certain predictive value.

Objective To investigate genotypes and antimicrobial susceptibility of Rhizobium radiobacter (R.radiobact-er)isolated from pediatric patients with bacteremia.Methods R.radiobacter strains from blood cultures of pediatric pa-tients with bacteremia from February 2013 through February 2014 were collected.16S rDNA fragment was amplified by polymerase chain reaction(PCR),bacterial genotypes were identified by pulsed-field gel electrophoresis (PFGE),antimi-crobial susceptibility testing were performed by Kirby-Bauer disk diffusion method.Results 13 isolates of R.radiobacter were isolated from 12 children with positive blood culture,which including 3 genotypes,the homology of 16S rDNA fragment and R.radiobacter IFM 10623 was up to 99%.According to CLSI 2003 standard,these 13 R.radiobacter were resistant to ceftazidime,piperacillin,ticarcillin,piperacillin/tazobactam,ticarcillin/clavulanic acid,aztreo-nam and polymyxin B,but sensitive to cefepime,doripenem,imipenem,meropenem,tobramycin,netilmicin,cip-rofloxacin,levofloxacin,and norfloxacin.In addition,cefotaxime and ceftriaxone showed larger inhibition zone. Conclusion Therapy of R.radiobacter infection should be based on antimicrobial susceptibility testing results;cefo-taxime and ceftriaxone are better selection for the therapy of R.radiobacter infection in pediatric patients.

Objective To investigate the effect of batroxobin on the blood-retinal barrier (BRB) and vascular endothelial growth factors (VEGF) in diabetic rats. Methods Sixty Sprague-Dawley rats were used to establish diabetic models by intraperitoneal injecting with streptozotocin (60 mg/kg), and were divided into 3 groups: diabetic group (n=20), batroxobin (40 mg/kg) group (n=20) and batroxobin (20 mg/kg) group (n=20). Twenty-five else rats were in control group. All of the rats were executed 7 days later. The function of BRB was observed by Evans blue method. Results concentration of VEGF protein was detected by enzyme-linked immunoabsorbert assay (ELISA). The results of each group were compared. Results The content of BRB leaked into retina was obvious lower in the control group than which in the other 3 diabetic groups(P0.05). The content of Evans blue was lower in the 2 diabetic groups with different dosage of batroxobin than which in the control group (P

Objective To investigate the effects of controlled hypotension induced with sodium nitroprusside (SNP) or nicardipine on hemodynamics during hip operation and postoperative hepatic and renal function.Methods Twenty ASA Ⅰ or Ⅱ patients aged 20-70 yrs weighing 50-80 kg scheduled for total hip replacement or open reduction and internal fixation of fracture of acetabulum were randomized to receive either SNP (group Ⅰ ) or nicardipine (group Ⅱ ) for induced hypotension during operation. Each group included 10 patients. Radial artery and right internal jugular vein were cannulated for BP and CVP monitoring. The probe of Hemo-Sonic ?100 esophageal supersonic hemodynamic monitor (Arrow U.S.A) was placed in the esophagus and fixed when best signal was obtained. ECG, hemodynamics including MAP, HR, CVP, CO and other parameters, SpO2 and PetCO2 were continuously monitored. Anesthesia was induced with propofol 2 mg?kg-1 , fentanyl 2-3 ?g? kg-1 and vecuronium 0.1 mg?kg-1 and maintained with 1.5% isoflurane and continuous infusion of propofol ( at 4-6 mg?kg-1 ?h-1 ) and intermittent i.v. boluses of vecuronium after tracheal intubation. MAP was reduced to 55-65 mm Hg with SNP (at a rate of 0.5-8.0 ?g?kg-1?min-1 ) or nicardipine (at 1.0-8.0 ?g?kg-1 ?min-1 ) . Intraoperative blood loss and blood transfusion and postoperative drainage from the wound were measured and recorded.Hemodynamic parameters were recorded before hypotension and 15, 30 and 60 min after start of induced hypotension and 15 and 30 min after recovery from hypotension. Hepatic and renal functions were measured before and after operation using total bilirubin, AST, ALT, BUN and creatinine. Results The two groups were comparable with respect to sex ratio (M/F) , age, height, body weight, duration of induced hypotension and operation. MAP and systemic vascular resistance (SVR) were significantly reduced and tachycardia developed during hypotension in both groups. The left ventricular ejection time was significantly prolonged and aortic blood flow (ABF) and cardiac output (CO) were significantly increased and CVP was lowered during hypotension as compared to the baseline values in SNP group. BUN was significantly reduced after operation ( P
