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 clinical significance of the changes of electrocardiogram (ECG) and cardiac markers for myocardial damage after on-pump coronary artery bypass grafting (CABG) and off-pump coronary artery bypass grafting (OPCABG). Method Monitoring 25 patients of OPCABG (OPCABG group) and 25 patients of CABG (CABG group) R wave amplitude of V4 and V5 on antorior electrocardiographic lead and simultaneously determining cardiac markers for myocardial damage creatine phosphokinase isoenzyme MB (CPK-MB), tropenin I (cTnI) and heat-shock protein 70 (HSPT0) on different lime. Results R wave amplitude of V4 and V5 on anterior electrocardiographic lead had no significant changes on 0, 6, 18 and 24 hours after OPCABG. On the contrary, R wave amplitude of V4 and V5 on anterior electrocardiographic lead decreased significantly on 0, 6 and 18 hours after CABG (P<0.01), and came back to preoperative values 24 hours after operation. The levels of CPK-MB and cTnI reached its peak and higher significantly for CABG than those for OPCABG on 24 hours after operation, 29.29 μg/L vs 5.98 μg/L and 6.74 μg/L vs 1.91 μg/L respectively. HSP70 increased significantly on 6 hours after operation in two groups, but median of HSP70 was higher significantly in CABG group (11044.5 pmol/L vs1702.0 pmol/L). In the first day after operation the HSP70 peak was correlated significantly with the level of CPK-MB(r=0.370, P<0.01) and cTnI (r=0.458,P<0.01). Conclusions Myocardial damage is significantly alleviated for patients of OPCABG comparing with those of CABG. The HSF70 in circulation may indicate the degree of myocardial damage.
