ObjectiveTo screen the colonization of multidrug resistant organisms (MDROs) and determine their risk factors in intensive care unit (ICU), so as to provide the basis of prophylaxis and treatment of MDROs colonization.Methods A prospective single-center study was conducted in ICU of China-Japan Friendship Hospital from June 2008 to December 2014. The nostril and anal swabs for each patient who stayed in ICU over 24 hours were collected. Each specimen was cultured and tested for drug sensitivity. Clinical findings and relative risk factors were collected. The risk factors of MDROs colonization were analyzed with univariate analysis. The independent risk factor was selected from the risk factors withP< 0.05 with logistic regression analysis to analyze the related factors of MDROs colonization in ICU.Results 1 672 patients were enrolled. At ICU admission, MDROs colonization was present in 604 cases (36.12%), of whom 62 cases (3.71%) were found to be colonized with methicillin-resistantStaphylococcus aureus (MRSA), 529 (31.64%) were colonized with extended-spectrumβ-lactamase (ESBL) enterobacteria, 7 (0.42%) were colonized with multidrug resistantAcinetobacter baumannii (MDR-AB), and 6 (0.36%) were colonized with multidrug resistantPseudomonas aeruginosa (MDR-PA). ICU acquired MDROs colonization were 197/1 068 (18.45%), among whom 24 patients (1.44%) were colonized with MRSA, 118 (7.06%) were colonized with ESBL enterobacteria, 50 (2.99%) were colonized with MDR-AB, and 5 (0.30%) were colonized with MDR-PA. By multivariable analysis, prior administration of more than two kinds of antibiotics [odds ratio (OR) = 2.352, 95% confidence interval (95%CI)=1.847 - 4.464,P = 0.002], prior use of broad spectrum antibiotics within 3 months (OR = 2.862, 95%CI = 1.458-5.631,P = 0.014), duration of prior antibiotic administration (OR = 1.781, 95%CI = 1.152 - 3.413,P = 0.003) and hospitalization days prior to ICU admission> 9 days (OR = 1.766, 95%CI = 1.235 - 3.986,P = 0.021) were independent risk factors of MDROs colonization on admission to ICU.ConclusionsHigh prevalence of MDROs colonization in ICU patients was found in our hospital, and ESBL enterobacteria was the predominant bacteria. ICU acquired MDROs colonization is also worth considering, especially for MDR-AB. Identification of risk factors for MDROs colonization may help identify and screen patients with high risk, and it is also instructive in prophylaxis of MDROs colonization/infection and restriction of the use of broad spectrum antibiotics.

Chinese Medical Ethics 1995;0(03):-
The construction of medical morality is linked closely with medical management.The foundation of micro-regulating model of medical morality can strengthen the management of medical morality,and make up for the deficiencies of the construction of medical morality;meanwhile,it can also enlarge the connatation of medical morality construction.

Chinese Medical Ethics 1994;0(05):-
On time of judging medical futility in departments of oncology, conflicts of interests exist,so more attention should be paid to the principles of rule,investigation,preaching and being public.Concrete methods are as follows:education for medical staff should be continued to make further progress;the advanced opinions of medical behaviours should be presented to guide clinical practice;the departments of oncology should cooperate positively with the ethics committees of hospitals.

Honest-trust plays an important role in the Chinese outstanding morals and culture, however the credit crisis is an outstanding problem in the professional ethics construction. Honest-trust is the soul of professional ethics construction, which is accountable, self-disciplining, honorable and extensive, therefore it should become the important category of the modern medical theory. And it is an effective way to disclose information and set up the honest-trust file for promoting the professional ethics construction.

Objective To analyze the association of gastrointestinal symptoms and sleep disturbance after Wen-Chuan earthquake. *Methods Using random sampling method, compared with Beijing publics at the same time, within two weeks, questionnaire was performed in the disaster area population.Gastrointestinal symptoms were diagnosed according to the Rome Ⅲ standard, and were analyzed in relation to sleep investigation. Results Among 956 disaster area individuals, 459 (48.0%) have gastrointestinal symptoms. Among 1021 Beijing publics, the corresponding number was 78(7. 6% ) ,which was significantly lower. The main gastrointestinal symptoms included abdominal pain ( 14. 0% ), distension ( 12. 1% ),constipation ( 10. 3 % ), heartburn (8. 6% )and dysporia (8. 3% ). Compared with Beijing publics (24. 4% ),the disaster area publics ( 83.7% ) with gastrointestinal symptoms had significant differences in sleep disturbance (P <0. 05 ). Early awakening with acratia had significant differences in disaster area publics (P < 0. 05). Conclusion There was relatively high incidence of gastrointestinal symptom after Wen-Chuan earthquake. The incidence of gastrointestinal symptom was related to sleep disturbance, and gastrointestinal symptoms were related to early awakening with acratia.
