Objective: To screen the best genetic engineering bacterium for the production of peptide antibiotic hPAB-? and evaluate its fermentation level in bottle. Methods:After analysis of the interest fusion protein expression levels of 8 recombinant bacteria containing 1-8 copies of human peptide antibiotic hPAB-? expressing plasmid respectively,2-5 copies expressing bacteria were chosen for the further study of their bacteria yield,expression forms of the target protein, dissolution of the inclusion bodies and the efficiency of fusion protein purification by affinity chromatography, then the best engineering bacterium with the certain copies of interest peptide expressing plasmid was screened out and its optimal fermentation parameters in bottle were also studied. Results:The recombinant bacterium transformed by 3 copies of interest peptide expressing plasmid was the best candidate for its bacteria yield (3.153 g/L) and fusion protein expression level (27.7%) were the highest among 1-8 copies candidates. The inclusion bodies of 3 copies target fusion protein could be easily dissolved by 8 mol/L urea and captured by Ni-NTA column. The elution of the fusion protein could be directly cleaved to monomer by adding 2 mol/L hydroxylamine, adjusting pH to 9.0 and incubating at 45℃ for 2 h. The optimal fermentation conditions of the selected recombinant bacteria were: culture the organisms with modified M9-CAA media at 37℃ and 160 r/min to (A 600 )≈2.5, then add IPTG to the final concentration 100 ?mol/L to induce the expression of target fusion protein for 5 h. Conclusion:The engineering bacterium containing 3 copies interest peptide recombinant expressing plasmid is the best candidate for the production of peptide antibiotic hPAB-?,and its fermentation parameters are confirmed.

AIM: To explore the probable mechanisms of diabetes-induced arrhythmias. METHODS: Diabetes was induced in male SD rats,using a single injection of alloxan into tail vein. Untreated age-matched animals were used as controls. All animals were observed by 2,4,6 and 8 weeks,respectively. Transmembrane potentials were recorded with conventional glass microelectrodes. RESULTS: Action potential duration(APD) at all level (APD10,APD20,APD30,APD50,APD70,APD90) was significantly lengthened in right ventricular papillary muscle from week 2 of diabetes. At week 8,APD was more lengthened at any level of repolarization than that at week 2. No differences were observed in the maximum rate of depolarization(V_ max ),overshoot(OS) and action potential amplitude(APA) as well as the resting membrane potential(RP) from the 2th to 8th week of diabetes. CONCLUSION: The results indicate that prolongation of APD may be prominently responsible for the increased incidence of cardiac re-entry-arrhythmias and sudden death,especially at late stages of diabetes.

Objective To observe the extent of bone coagulation and the thermal field distribution created in ablating the swine vertebral bodies in vitro with multi-polar radiofrequency and to discuss the correlation between the electrode position in the vertebral body and the safety of the spinal cord as well as the soft tissue injury around the vertebral body. Methods Thirty fresh adult porcine vertebrae, were randomly and equally divided into two groups. The depth of the electrode needle was 10 mm or 20 mm. When the ablation process reached to a stable state, the temperature at the scheduled spots was estimated. Twenty minutes after ablation, the vertebral body was cut along the electrode needle plane and also along the plane perpendicular to the electrode needle to observe the extent of bone coagulation. Results The temperature at the scheduled spots reached to a stable state in 3.5 minutes. The more close to the electrode the spot was,the more quickly the temperature rose. No soft tissue injury around the vertebral body was observed in both groups and no spinal cord injury occurred when the electrode needle was 10 mm or 20 mm deep in the vertebral body. Conclusion In treating vertebral metastases, the radiofrequency ablation is safe and reliable if the posterior wall of the vertebral body remains intact.

Objective To investigate the etiological and antibiotic resistance profile in the old patients with bloodstream infection (BSI).Methods Microbiological and clinical data were collected and reviewed retrospectively for the patients with confirmed bloodstream infection and at least 65 years of age who were treated as inpatients in Tongling People′s Hospital from January to December 2015.Results A total of 107 strains of pathogen were isolated from the blood samples of 107 patients with bloodstream infections, of which community-acquired BSI accounted for 57.9 % (62/107), and hospital-acquired BSI 42.1 % (45/107). Gram negative bacilli accounted for 67.7 % in the pathogens of community-acquired BSI and gram positive cocci accounted for 55.5 % in the pathogens of hospital-acquired BSI. More male BSI patients were secondary to respiratory tract infection than female patients (P<0.001), while more female BSI patients were secondary to urinary tract infection than male patients (P<0.001). Of the 107 isolates, gram negative bacilli, gram positive cocci and fungi accounted for 55.1 % (59/107), 42.1 % (45/107) and 2.8 % (3/107), respectively. The top six pathogens were E. coli (30.9 %), coagulase negativeStaphylococcus (CNS) (20.6 %), S. aureus (10.3 %),K. pneumoniae (6.5 %),Enterococcusspp. (6.5 %) and Acinetobacter spp. (4.7 %). About 51.5 % of the E. coli isolates and 28.6 % of the K. pneumoniae isolates produced extended-spectrum β-lactamases (ESBLs).E. coli isolates showed low resistance rate (< 10 %) to amikacin,cefoxitin and piperacillin-tazobactam. No E. coli isolate was found resistant to carbapenem. About 14.3 % to 28.6 % of K. pneumoniae isolates were resistant to carbapenems. No tigecycline-resistant K. pneumoniae was found. The prevalence of MRSA and MRCNS was 36.4 % and 72.7 %, respectively. No staphylococcal isolates were found resistant to vancomycin, teicoplanin or linezolid. One strain of E. faecium was identified as resistant to vancomycin (VRE).Conclusions This surveillance data indicate that gram negative bacilli play an important role in the BSI of old patients. E. coli and CNS are the most common pathogens. We should pay more attention to the effect of gender and site of infection on the BSI in old patients.
