Objective To investigate the distribution and effect of class Ⅰ integron in 40 strains of clinical multi-resistant Enterobacter cloacae. Methods Kirby-Bauer method was used to analyze the drug resistance of 40 strains of multi-resistant Enterobacter cloacae and the drug resistance gene was analyzed by polymerase chain reaction (PCR). Results 28 strains (70.0%) of 40 clinical isolates were observed to contain class Ⅰ integron. Drug resistance test showed their resistance rate to 10 kind of an-tibaeterials as follow: 7.5% to imipenem, 5.0% to meropenem, 75.0% to piperacillin-tazobactam,55.0% to amikacin, 12.5% to cefepime, 52.5% to ceftazidime, 55.0% to cefotaxime, 90.0% to ceftriaxone;81.8% to ticarcillin-clavutanic acid, and 85.0% to ciprofloxacin. Conclusion This study shows that the resistance situation of Enterobacter cloacae isolates is very serious, and class Ⅰ integron may play an important role in the muhidrug resistant mechanism.

Teaching Inspection is the important part of the Inspective system for teaching quality in medical universities and colleges,which acts on inspection,instruction and consultation for teaching.Teaching Inspection system has been set up in medical universities and colleges.

In order to investigate the effects of hyperbaric oxygen (HBO) on the proliferation and differentiation of human osteoblasts isolated from alveolar bone under various pressure and exposure time, osteoblasts from human alveolar bone were seeded in 24 well plates at a cell density of 2 500 cells per well. There are four treatment groups which were 2.4ATA for 90 min, 2.4ATA for 30 min, 1.5ATA for 90 min and 1.5ATA for 30 min. Osteoblasts culture were treated one time everyday for up to 10 days in a temperature and humidity controlled custom-made seven-litre hyperbaric unit. Control samples were incubated in a standard humidified incubator at 37℃ containing 5% CO2 and 95% atmospheric air. Proliferation of osteoblasts were evaluated by WST-1 assay before and 16 h after HBO on day 1,2,3,4,6,8,10. The cytotoxic effect of HBO on osteoblasts was assessed by a toxicology assay kit. For differentiation study, osteoblasts were seeded in 96 well plates at a cell density of 10 000 cells per well. After 3 days normal culture, medium was changed to osteogenic medium. Subsequently, cultures were exposed daily to HBO of 2.4ATA for 90 min and 1.5ATA for 90 min up to 13 days. Mineralization was evaluated by calcium deposition assay, alkaline phosphatase (ALP) activity and von Kossa staining. To assess the effect of pressure on cell proliferation and differentiation, hyperbaric air treatment was observed in this study. It showed that HBO treatment promotes proliferation of osteoblast in the presence of 10% foetal calf serum (FCS). No significant change in extracellular LDH activity before and after HBO treatment. The study of differentiation demonstrated that HBO enhanced differentiation associated with increased bone nodule formation, calcium deposition and alkaline phosphatase activity. These result suggests that HBO treatment significantly stimulated osteogentic differentiation, which implies a potential application of HBO in bone tissue engineering.

Medical science is a practical subject.It is the basic characteristic of the medical education to combine the theoretical knowledge with practice,therefore to emphasize and construct and bring into effect effectively the experimental and practical teaching system is very important and significant for the cultivation of medical professionals.

0.05).In the treat groups seralbumin and plasma osmotic pressure showed significant difference before and after treatment(P0.05).CONCLUSION: There were some adverse effects in the rhGH treatment for malnutritional COPD patients,but they won't influence the treatment.

Objective To construct shRNA expression vector of SURVIVIN for RNAi-mediated therapy of lung cancer.Methods DNA templates of SURVIVIN shRNA were designed,synthesized and cloned into the shuttle vector to get recombinant plasmids.After plasmids were transfected into A549 cells,the one with the most repression was screened by means of RT-PCR.Then MTT and Western blot were done to ascertain whether the proliferation of A549 cells were inhibited and SURVIVIN was down-regulated.Results The recombinants were constructed and screened successfully.The proliferation of A549 cells and SURVIVIN expression were repressed.Conclusion Mediated by RNAi,SURVIVIN expression was down-regulated,which suggested a potential gene therapy of huaman lung cancer.

Objective To study the application of 64-slice spiral CT coronary artery angiography in children.Methods 21 pediatric patients were undergone 64-slice spiral CT coronary artery angiography.6 of 21 patients underwent selective coronary artery angiography.All patients underwent echocadiogram.Results 12 patients were showed having abnormal coronary artery,including double openings at right coronary artery in 3,RCA an LCX origin together from right aortic sinus in 2,LAD and right coronary artery trunk origin together from right aortic sinus in 2 and LAD and LCX origin directively from left aortic sinus respectively in 2,left coronary artery trunk origin from pulmonary artery trunk in 1 case,normal origin of coronary artery but their branches to be tortuous and expansive in 1 case,left coronary artery trunk closed up and right coronary artery to be tortuous in 1 case.Coronary artery simple or multiple tumor-like dilation in 6 cases with Kawasaki disease,3 patients with normal CT coronary artery angiography.In comparing with DSA,the accuracy of 64-SCT in diagnosis pediatric coronary artery disease was 100%.Conclusion As a minimally invasive examination,64-SCT coronary angiography is a valuable method to detect and diagnose the pediatric coronary artery diseases.

Obiective To screen serum biomarkers in patients with hepatocellular carcinoma (HCC)by SELDI-TOF-MS technique.Methods SELDI-TOF-MS technique and CM10 Protein Chip were used to detect serum protein patterns of 46 patients with primary hepatic carcinoma and 64 healthy persons.The different proteins were obtained by the Biomarker Wizard software between the patients and healthy persons.The best biomarker of primary hepatic carcinoma was selected by evaluating the sensitivity and specificity of the protein.Results 16 protein peaks were obviously different between the patients and the healthy persons (P ＜0.05).The protein peaks of m/z 6845.70 had the highest diagnosis value with a sensitivity of 89.1％ (41/46)and specificity of 87.5 ％ (56/64).This protein was likely to be a part of the immunoglobulin heavy chain variable region.Conclusion The protein of m/z 6845.70 is potential biomarkers for the diagnosis of HCC.SELDI-TOF-MS technique is a quick,simple,convenient and high through-put technology for diagnosis of hepatocellular carcinoma.

Objective Toinvestigatetheimpactofthedifferentrupturepoints(sac,neck,andtop) of intraoperative aneurysm rupture (IAR)on the prognosis of patients in anterior circulation aneurysm clipping.Methods Theclinicaldataof135consecutivepatients(148aneurysms)acceptedmicrosurgical aneurysm clipping from May 2009 to March 2012 were analyzed retrospectively. The prognostic evaluation of the patients after procedure was assessed by using the Glasgow outcome scale (GOS). The different aneurysm rupture points of IAR were used as influencing factors,and the relationship between the different rupture pointsandtheprognosisofpatientswasanalyzed.Results Duringclippingof148aneurysmsin 135 patients,31 aneurysms in 30 patients had intraoperative rupture (20. 9% of the aneurysms, 22.2% of the patients). Nine rupture points occurred on the top of aneurysms,17 occurred on the sac,and 5 occurred on neck. The Glasgow outcome scale (GOS)scores 5,4,3,2 and 1 were in 17,8,2,1 and 2 patients,respectively. A total of 25 patients had good prognosis and 5 cases had poor prognosis. There were no significant differences in the impact of different rupture points of IAR on the prognosis in patients of IAR (OR,100. 00,95% confidence interval 6. 764-18. 344,P=0. 006). Of the 25 patients with aneurysm sac or top rupture,1 case had poor prognosis. Of the 5 patients with aneurysm neck rupture, 4caseshadpoorprognosis.Conclusion Inanteriorcirculationaneurysmclipping,thedifferent aneurysm rupture points may have significant impact on the prognosis of patients,the aneurysm neck rupture is a main factor for resulting in the poor prognosis of patients.
