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 efficacy of rhubarb acupoint sticking joint shuganjieyu diet in the treatment of chronic functional constipation patients with depressive anxiety.Methods 120 patients of chronic functional constipation with depression anxiety were selected,they were randomly divided into control group and obser-vation group,60 cases in each group.The patients in the control group were given promoting gastrointestinal motility drugs mosapride capsules,and orally given laxatives rhubarb with sodium bicarbonate.The patients in the observation group were treated with topical rhubarb acupoint,and orally given medicated shuganjieyu diet.7 days for a course of treatment,the patients were treated for four courses.The clinical efficacy of the two groups,defecation interval and fecal nature,SAS,SDS scale score changes and quality of life (PAC -QOL)scale score changes before and after treatment and adverse reactions during treatment were recorded.Results The total effective rate of the observation group was 90.00%,which of the control group was 91.67%,the difference between the two groups was not significant (χ2 =0.32,P >0.05).Before treatment,the bowel movement and stool ratings between the two groups had no statis-tically significant differences (t =0.23,0.33,all P >0.05).After treatment,the two points of the two groups were significantly decreased,but the differences between the two groups were not significant (t =0.18,0.41,all P >0.05).Before treatment,the SAS,SDS scale scores between the two groups had no statistically significant differences (t =0.78,0.69,all P >0.05).After treatment,the SAS,SDS scores of the two groups were significantly decreased, which of the observation group decreased more significantly than those of the control group (t =4.18,4.72,all P <0.05).Before treatment,the PAC -QOL scale scores for each dimension level had no statistically significant differ-ences (t =0.16,0.21,0.42,0.20,all P >0.05).After treatment,the dimensions of the two groups showed a decline trend,and those of the observation group decreased more significantly than the control group (t =2.10,3.56,2.76, 2.34,all P <0.05).In the control group during the treatment,2 cases of diarrhea,three cases of dry mouth,the patients were improved after given symptomatic treatment.No serious adverse event occurred during therapy in the observation group.Conclusion Rhubarb acupoint joint shuganjieyu diet in the treatment of chronic functional constipation patients with depression anxiety has significant clinical effect,which can significantly improve patients'depression and anxiety scores,quality of life,and without significant adverse reactions,it is worthy of clinical applica-tion.

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.

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
