Objective To investigate the drug sensitivity and distribution of main pathogenic pathogens in hospitalized patients with respiratory hospital diabetes bacteria and provide reference for the prevention and treatment of diabetes mellitus in experimental infection in patients with respiratory hospital.Methods 69 cases of diabetes mellitus complicated with respiratory infection were selected, their clinical data ( laboratory, imaging and etiological examination data) were complete,and their intact specimens for testing and identificated were throat swabs, sputum smear, sputum culture, protected specimen brush sampling, pathogens culture, and drug susceptibility test of pathogenic bacteria were isolated from the statistical data of 69 patients and prognosis.Results 69 strains of pathogenic bacteria were isolated, identified and isolated from the specimens of all the patients in the study.Among them, there were a total of 86 strains of pathogenic bacteria, including gram positive bacteria (46 strains), gram negative bacteria (27 strains) and fungi (13 strains) .Staphylococcus aureus, Streptococcus pneumoniae, Staphylococcus epidermidis to teicoplanin, clindamycin, amoxicillin and levofloxacin sensitive rate is less than 50%, while to oxacillin, vancomycin, linezolid, ampicillin, imipenem, moxifloxacin susceptibility rate >50%.Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae to ceftriaxone, ceftazidime, amoxicillin, amikacin drug sensitivity of less than 50% of cefoxitin, piperacillin/tazobactam, cotrimoxazole, imipenem, meropenem, netilmicin susceptibility rate >50%.69 patients were diagnosed before treatment with antiviral drugs, antibiotics, antibiotics adjusted according to the etiology and drug sensitivity test results and antiviral drugs, improved in 49 cases of patients to the hospital treatment of 14 cases, 6 cases were converted to sepsis after rescue invalid death.Conclusion The diabetic patients hospitalized in respiratory pathogens of nosocomial infection in a wide range of pathogen susceptibility differences , understand the distribution of pathogens in patients with regular and drug resistance, provide guidance for the prevention and treatment experience, reduce the infection rate of patients with respiratory infection in patients with hospital provided treatment of high pertinence has important significance.

Objective To investigate the incidence of sharp injury (SI)among health care workers(HCWs)in dif-ferent levels of hospitals in Gansu Province,so as to improve HCWs’precaution awareness,standardize behavior, and provide guide for making occupational precaution measures.Methods From January to December 2012,HCWs in 38 medical institutes in Gansu Province were selected with stratified random sampling,HCWs were surveyed through questionnaires and interview.Results A total of 11 358 questionnaires were received,the incidence of SI was 9.87%(n=1 121),case rate was 12.60%(n=1 431),the frequency of SI was 1.05 times/(person·month).SI rates of different genders,positions and years of working were statistically different (all P <0.05).The main medical devices cau-sing SI were syringe needle,venous transfusion scalp needle and surgical suture .SI caused by known sources were 1 099 times (76.80%);980 times (68.48%)of SI were induced by contaminated sources,474 (48.37%)of which were blood-borne diseases,bloodborne disease exposure accounted for 33.12%.Among bloodborne disease exposure,hepatitis B virus accounted for 74.25%,Treponema pallidun 13.10%,hepatitis C virus 12.01% ,and human immunodeficiency virus 0.64%.Conclusion There is a high incidence rate of SI among HCWs in Gansu Province,it is a very important public health problem which needs to be solved.

Objective To evaluate the application value with Energy Spectrum CT multi -parameter quanti-tative value in differentiating pulmonary occupying lesions (>0.5cm in diameter).Methods Those were retrospec-tively analyzed on 58 cases in pulmonary occupying lesions performed spectrum dual -phase enhanced CT scan and confirmed by pathology,including malignant group 48 cases;10 cases of benign group.Iodine content(IC)was meas-ured in arterial phase(AP)and venous phase (VP)in iodine based on the image and the level of the aorta,and nor-malized iodine concentrations were calculated in the two phases lesions compared with aorta,and the difference between the two normalized iodine concentrations ICD (ICD =NICvp -NICap).To measure the CT value of lesions on 50keV and 100keV energy image,and calculate the energy attenuation curve slope,namely |Hu (100 kev -50kev)/Hu50 |.The differences of NIC,curve slope,and ICD were compared between benign and malignant pulmonary occupying lesions using independent sample t test method.Results In two phase scan,NIC,curve slope of the venous phase and ICD in malignant group were significantly higher than the benign group,(NIC,curve slope of the venous phase and ICD of the malignant group:NICap:0.180 ±0.051,NICvp:0.463 ±0.086,1.696 ±0.475,ICD:0.284 ± 0.071;NIC,curve slope of the venous phase and ICD of the benign group:NICap:0.123 ±0.062,NICvp:0.290 ± 0.119,1.169 ±0.582,ICD:0.166 ±0.073,),but there was no significant difference between the patients with benign and malignant lesions in curve slope of the arterial phase.Conclusion Energy spectrum CT dual -phase enhanced scan can differentiate the nature of benign and malignant pulmonary occupying lesions,and has certain clinical application value.

Objective To investigate source and solution of junior college nursing students' negative emotions during clinical practice in pediatric department and provide evidences for promoting clinical nursing education.Methods Phenomenological research from qualitative study was performed on 10 nursing students in pediatric department via depth interview. Negative emotions and its source during clinical practice were analyzed.Results There were five themes of negative emotions of nursing students in pediatric department as following: numerous simple labors, less opportunities for technical operations, no confidence of patients, hard communication with family members and lack of ability in psychological adjustment. Several solutions were used by nursing students.Conclusions It is important to care the emotional experience of pediatric nursing students. Timely attention and psychological counseling, reformation and innovation of teaching model, improving learning motivation, cultivating professional interests, ameliorating learning outcomes and quality are necessary.

CD4+CD25+ regulatory T cells (CD4+CD25+ Tregs) have been shown to play a regulatory or suppressive role in the immune response and are possibly relevant to the pathogenesis of autoimmune diseases. In the present study, we attempted to investigate the frequency of CD4+CD25+ Tregs in peripheral blood (PB) of collagen-induced arthritis (CIA) rats during the development of arthritis, to determine whether their frequency is involved in the immunoregulation of this disease. The results showed that normal rats had similar frequencies of CD4+CD25+ Tregs in PB during the experiment time, expressed as a percentage of CD4+CD25+Foxp3+ T cells among the CD4+ T lymphocyte population. In contrast, the frequency of CD4+CD25+Foxp3+ T cells in CIA rats was found to change during the development of arthritis. In CIA rats, there is a significant negative correlation between the frequency of CD4+CD25+Foxp3+ T cells and paw swelling (r=-0.786, p< 0.01). The relationship between the frequency of CD4+CD25+Foxp3+ T and immune activation was not found in normal rats. During the time course, the frequency of CD4+CD25+Foxp3+ T was lower in CIA rats than in normal ones. The data suggest that the frequency of PB CD4+CD25+ Tregs may be a promising marker for arthritis activity.
