Objective To observe some current situation in elderly Diabetes Mellitus with ethics in China,and to explore the method to solve the problems.Methods To analyze the problems with ethics.Results To advance some methods for solving the ethical problems associated with doctors and nurses,family and society.Conclusions Only by improving the minds of medical ethics of doctors and nurses,contributing infinite patience,attention and care,offering elderly diabetes mellitus patients much more help and ethical care with their family and society,they can get better clinical diagnosis and treatment,spiritual consolation,life care and economic support.

Objective To investigate the clinical characteristics,distribution and drug sensitivity of pathogens causing intravenous catheter-related bloodstream infections (CRBSIs) in pediatric intensive care unit (PICU) so as to use antibiotics reasonably.Methods All patients with CRBSIs in PICU of Guangdong General Hospital from September 2009 to September 2014 were investigated and the drug resistance profiles of pathogens causing CRBSIs were also analyzed retrospectively.Results Between 2009 and 2014,there were totally 10 834 catheter days and 23 episodes of CRBSIs with an incidence of 2.1 infections per 1 000 catheter days.Catheter indwell time ＜ 7 days in 9 cases (39.1％),8 to 14 days in 10 cases (43.5％),14 to 21 days in 4 cases (17.4％).There were 13 strains (56.6％) of gram-positive bacteria,5 strains (21.7％) of gram-negative bacteria and 5 strains (21.7％) of fungi.The main pathogens causing CRBSIs were coagulase negative Staphylococci (7 strains,30.4％),Staphylococcus aureus (3 strains,13.0％),Candida albicans(3 strains,13.0％),Candida parapsilosis(2 strains,8.7％),and Enterobacter cloacae (2 strains,8.7 ％).The susceptibility to Vancomycin,Linezolid and Teicoplanin of coagulase negative Staphylococ cus such as S.epidermidis and to Imipenem,Piperacillin/Tazobactam,Cefoperazone/ Sulbactam and Amikacin of gram-positive bacteria arrived at 100.0％,respectively.The candida were 100％ susceptible to Amphotericin B,5-Flucytosine,Fluconazole and Voriconazole.Twenty-one cases (91.3％) received antibiotic treatment versus no antibiotic in 2 cases (8.7％).The average number of antibiotic kinds administered on the patients with fungal infection was 4.4,bacteria were 1.4.Ten cases (43.5％) treatment with 1 kind of antibiotic,4 cases (17.4％) with 2,4 cases (17.4％) with 3,5 cases (21.7％) with more than 3.Twenty-two cases (95.7％) cured and 1 case died (4.3％).Conclusions The major species of pathogen causing CRBSIs was coagulase negative staphylococci in PICU.It is critical for clinicians to guard against fungal infection because of prolonged catheter indwelling time and more antibiotics administered before indwelling catheter.It is effective way to prevent the CRBSIs by reasonably using antibiotics and shortening the time of catheter indwelling.Monitoring CRBSIs pathogenic bacteria distribution and drug susceptibility helps reasonable administration of antibiotics in the earlier time.
