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 expression of neive growth factor (NGF) in the ectopic endometrium in adenomyosis patients,and explore the relationship between NGF expression and innervation or pain scales.Methods From Mar.2009 to Oct.2009,45 adenomyosis patients undergoing hysterectomy in Obstetrics and Gynecology Hospital of Fudan University were enrolled in this study,which were classified into 33 cases in pain group and 12 cases in non-pain group based on symptom.The degree of dysmenoreal,chronic pelvic pain and dyspareunia was evaluated by visual analogue scale,including no pain,mild to moderate pain and severe pain group.In the mean time,26 patients with leiomyoma or cervical intraepithelial neoplasia Ⅲ (CIN Ⅲ)undergoing hysterectomy were defined as control group.Ectopic endometrium from experimental group and eutopic endometrium from control group were collected in the surgery.The expression of NGF was examined by immunohistochemistry.The density of protein gene product (PGP)9.5 positive nerve fibers was detected by immuno-fluorescence.Results The NGF level and the density of PGP 9.5 positive nerve fibers in adenomyosis pain group (0.25 ± 0.08,16 ± 8) were higher than adenomyosis painless (0.19 ± 0.05,P =0.007 ; 11 ± 5,P =0.018) and control group (0.18 ± 0.05,P =0.000;9 ± 4,P =0.000).The NGF level and the density of PGP9.5 positive nerve fibers in severe dysmenorrheal group(0.29 ± 0.07,19 ± 10) were higher than mild to moderate dysmenorrheal (0.22 ± 0.07,P =0.018 ; 13 ± 4,P =0.035) and painless group (0.18 ± 0.05,P =0.000 ; 11 ± 5,P =0.006) of adenomyosis patients.There was no difference of NGF level and the density of PGP 9.5 positive nerve fibers in chronic pelvic pain group and no chronic pelvic pain group of adenomyosis patients,so was dyspareunia group and no dyspareunia group.Conclusion The increased NGF level of adenomyosis nodules and improving innervation might be involved in the mechanism of adenomyosis related pain.

Objective To investigate the ultrasonographie characteristics of basal cell adenoma in salivary gland and to improve the coincidence of ultrasound diagnosis for the tumor. Methods The ultrasonographic characteristics for 31 cases of basal cell adenoma which were pathologically confirmed were analyzed and summarized combining with its pathological characteristics retrospectively. A differential diagnosis between basal cell adenoma and pleomorphic adenoma was also made. Results Basal cell adenomas of salivary gland showed low and equivalent internal echoes,sometimes with colliquation in their substantial component. They showed enhanced posterior echo,middle hardness, clear boundary and regular shape. Color Doppler flow signals were also found in the center or periphery of the tumors. Conclusions The ultrasonic manifestation of the basal cell adenoma has its own characteristics,which is complied with its pathological basis. The combination of ultrasonography and clinical information is conducive to differentiate basal cell adenoma and pleomorphic adenoma of salivary gland.

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.

AIM: To construct a recombinant adenovirus vector which regulated expression of mouse transforming growth factor beta (TGF-?1). METHODS: Total RNA was extracted from Balb/c mice spleen pre-treated with Con A to clone TGF-?1. pTRE-shuttle vector was used as mediator to ligate TGF-?1 gene and the backbone of the replication-incompetent adenoviral vector. The constructed recombinant adenovirus contains tetracycline-responsive element which can regulate the expression of inserted genes. Identifying the desired recombinant adenovirus, it was packaged in HEK 293 cells. Supernatant of high titer adenovirus was collected to detect the TGF-?1 gene expression by ELISA kit. RESULTS: The constructed recombinant adenovirus had been identified by restriction endonucleases cutting, sequencing and PCR. In the supernatant of infected cells, it expressed the mice TGF-?1 in high concentration to 91.16 ng/L. CONCLUSION: The mice TGF-?1 recombinant adenovirus has been built which make a basis for further research and use in gene therapy.
