Objective To analyze the effect of PDCA cycle quality management model on multi-drug resistant organism (MDROs) infec-tion control in a tertiary rehabilitation hospital. Methods From March, 2013 to December, 2015, targeted surveillance of MDROs infection control was performed with PDCA cycle quality control. The MDROs detection rate, the awareness rate of MDROs prevention and control, the rate of doctor issuing isolation orders and execution rate of medical sanitation disinfection and isolation were analyzed. Results The de-tection rates of methicillin-resistant staphylococcus aureus and Carbapenem-resistant Pseudomonas aeruginosa decreased (χ2>3.922, P<0.05), while no significant difference was found in the detection rate of multidrug-resistance Acinetobacter baumanii (χ2=8.775, P=0.071). The awareness rate of MDROs prevention and control, the rate of doctor issuing isolation orders and execution rate of medical sanitation dis-infection and isolation significantly improved (χ2>399.17, P<0.001). Conclusion PDCA cycle quality management model played an impor-tant role in the prevention and control of MDROs in rehabilitation hospital.

Retrospectively from February, 2006 to June, 2009 the clinical characteristics of 14 misdiagnosed cases of insulinoma in the First Affiliated Hospital of Zhengzhou University were analysed. The rate of misdiagnosis was 38% ( 14/37). The rate of IRI/G≤0. 3 was 33%. Insulinoma has often been misdiagnosised when IRI/G≤0. 3. Hence a diagnosis of insulinoma can not be excluded with this IRI/G rate.

Objective To construct the teaching model of medical statistics in universities of TCM through the questionnaire of knowledge,attitude and practice structure.Methods Medical statistics KAP questionnaire survey was conducted among postgraduates using proportional stratified sampling according to the grade.It describes the present situation and calculates the knowledge loss coefficient,knowledge demand index and behavioral application intensity of medical statistics.The Chi-square test was used to analyze the differences among different grades.Results 109 questionnaires were withdrawn.The recovery was 83.84％.45 cases (41.3％) were first year postgraduate,33 cases (30.3％) were 2nd year postgraduate,and 31 cases (28.4％) were 3rd year postgraduate.At the knowledge level,the knowledge loss coefficient of the second year postgraduates was 0.635,and there was no statistical difference (P=-0.651) vs the first year postgraduate (0.638).At the attitude level,Knowledge demand index had no statistical significance difference (P=0.213)between postgraduates in grade two (96.87％) and grade three (75.00％).Most medical postgraduates held positive attitudes toward medical statistics,hoping to strengthen the training of their application ability such as medical statistics in design and research thinking (29.18％),the statistical methods selection and the interpretation of the results (31.53％) and the statistical software operation (36.07％).At the practice level,the percentage of application intensity with statistical methods of third-year postgraduates (100.00％) was higher than the second-year postgraduates (37.50％),and the second-year postgraduates higher than the first-year postgraduates (20.45％).And with the growth of year,the percentage of application intensity was gradually increasing (P=O.O03).Among them,published scientific papers accounted for 16.5％,and 58.6％ paper grade concentrated in the core journals.Conclusion Application development should be enhanced by modularization teaching with practical issues.
