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.

Objective To investigate the efficacy of concurrent interventional cisplatin,leucovorin,fluorouracil,hydroxy camptothecin chemotherapy plus radiotherapy in patients with Ⅳ stage middle-lower section esophageal cancer.Methods The subjects were all the patients with Ⅳ stage middle-lower section esophageal cancer.Among of them,42 patients,via artery,had been enrolled for concurrent interventional cisplatin,leucovorin,fluorouracil,hydroxy camptothecin chemotherapy plus radiotherapy.40 patients were given irradiation.Results The incidence rate of Ⅰ grade esophageal X-ray in the former group was 57.1%,and that in the later group was 25.0%,and the parameters had significant difference(?0.05).Conclusion Concurrent interventional cisplatin,leucovorin,fluorouracil,hydroxy camptothecin chemotherapy plus radiotherapy may be attributed to progression of Ⅳ stage middle-lower section esophageal cancer.

Actions of "not None" ,termed as notorious actions,have imposed side effects on society. From the levels of medical management and department directors, the essay analyzed the manifestation, effects and cauls of the actions of "not None". Some suggestions were given to control these actions.

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.

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.

ObjectiveTo establish an accurate method for simultaneous determination of plasma Kyn and Trp by HPLC-UV detection.Methods Kyn and Trp were separated on Agilent Hypersil ODS column using 3-nitrotyrosine as internal standard.The mobile phase consisted of 15 mmol/L sodium acetateacetic acid (pH 5.5):acetonitrile 94∶ 6(v/v) at a rate of 0.8 ml/min.The chromatographic separation was performed at 25 ℃.The eluate was monitored with programmed wavelength setting at 360 nm from 0 to 4 min for Kyn and at 302 nm from 4 to 5 min for Trp.The method was applied to determination of plasma Kyn and Trp in 8 chronic glomerulonephritis,10 idiopathic thrombocytopenic purpura,15 chronic hepatitis B virus patients and 15 healthy controls from September to December in 2010.The differences were compared using ANOVA and SNK methods.Results The retention time of Kyn and Trp were 2.9 min and 4.4 min,respectively.For Kyn,the assay was linear from 0.44 μmol/L to 18.30 μmol/L.For Trp,the linearity was from 3.67 μmol/L to 470.00 μmol/L.The detection limits were 0.014 μmol/L for Kyn and 0.122 μmol/L for Trp,respectively.The within-day CVs were ＜ 3％ and the between-day CVs were ＜ 4％.The mean recoveries yield were in the range of 92.29 to 104.40.The plasma concentrations of Kyn were ( 1.59 ± 0.28),(2.73 ± 0.56),(2.69 ± 0.44) and ( 1.54 ± 0.48 ) μmol/L,the plasma concentrations of Trp were (59.8 ± 10.0),(46.1 ± 11.7),(58.5 ±8.0) and (41.4±13.1) μmol/L,the Kyn/Trp were (0.027 4±0.007 5),(0.061 6 ±0.016 5),(0.046 7 ±0.009 1) and (0.038 3 ±0.007 5)in controls,chronic glomerulonephritis patients,idiopathic thrombocytopenic purpura patients and chronic hepatitis B virus patients,respectively.There were significance difference of Kyn,Trp and Kyn/Trp amony the four groups (F=23.734,8.463,20.921,all P＜0.01).Conclusion The method is simple,fast,and suitable for applicability to clinical measurement.

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.
