Objective To understand the current situation of medical postgraduates'!honesty edu-cation, find the weak point and explore new ways of the honesty education. Methods The honesty educa-tion survey questionnaire was designed and conducted to the postgraduates of Grade 2014 in Peking University Health Science Center. The research contents included the basic information of postgraduates, honesty cognition, clean and self-discipline, honesty education, the recommendation of honesty education and the application of honesty education carrier. 1 038 questionnaires of a total of 1 142 questionnaires were recovered and the recovery rate was 90.9%. EPIData3.0 software was used for double entry and database establishment, and SPSS 19.0 software for statistical treatment. Results 82.3% (854) of the postgraduates recognized the work of clean government, but only 62.1% (644) of the postgraduates concerned about it. 78.3% (813) of the postgraduates expressed hatred for the dishonest behavior and hoped to eliminate it. 77.6%(806) postgraduates often paid attention to honest education content which was pushed by the new media. 16.5% (171) postgraduates thought that the new media was very important to the honest cognition. Conclusions We should pay more attention to medical postgraduates'!honesty education, find its weak points according to the investigation and make full use of the network and new media. And at the same time we should combine the actual environment to establish a hierarchy of honesty education system, and carry out honesty education through total environment which contains the school administrators, instructors/head teachers and tutors.

Objective The study analyzes the inadequacies of the research integrity educational practice for the medical postgraduate students in the present stage of China.Furthermore,the paper puts forward improvement suggestions and clears the direction for further efforts.Methods From the perspective of the educational law about cognition,emotion,will and behavior,the comparative analysis method is used,based on the rich experience in the United States.Results There are inadequacies of the research integrity educational practice for the medical postgraduate students in China,including that students lack knowledge learning motivation,and the pattern of education is simple.There are not enough emotional experience channels and the participation of students.Students lack honesty will training,and the intensity of supervision and punishment is not strong.The honesty recognition mechanism is weak,and cannot be used to guide practice.Conclusions In order to improve the level of the research integrity for the medical postgraduate students in China,we should optimize the system,follow the law of education,strengthen the transmission of knowledge,put the academic honesty education into normal work,enhance the emotional experience,build a participatory mechanism,highlight the positive guide,and increase the intensity of punishment.

Sequential monitoring of chimerism after hematopoietic stem cell transplantation is important for disease prognosis, improving transplantation success rate, and reducing relapses of the original diseases. The application of molecular genetic markers in combination with quantitative PCR to the assessment of chimerism,in particularly the dynamic quantitative analysis of lineage-specific chimerism, can provide important guidance for clinical practice.

Natural killer (NK) cells are key members of the innate immune system.The capability of NK cells to kill hematological tumor cells mainly depends on the synthesis of stimulatory and inhibitory signals on the cells surface.In recent years,allogeneic haplo-identical NK cells have shown positive effect of hematologic tumor in hematologic stem cell transplantation and adoptive immunotherapy,and the natural killer cell-based immunotherapy would be applied in clinic.

Objective To study the safe drinking duration of purified drinking water of water dispensers, the relationship between the sanitary quality of purified drinking water and the structure of the water dispensers. Methods 30 drinking water dispensers were collected from the market and divided into 3 groups based on the structural types. A following-up experimental observation for the changes of the microbiological indexes of the water samples from the taps of water dispensers with different structures during the different prolongating operating period was carried out. Results The safe drinking duration was ≤ 4 days for the purified drinking water sampled from the taps of the water dispensers with common type at the normal atmospheric temperature and ≤ 14 day for water dispensers with bacterial inhibition type. The sanitary quality of the purified drinking water sampled from the taps of water dispensers was associated with the structural type of water dispensers, but not the brands of water dispensers. Conclusion The experimental results of the water samples collected from the taps of water dispensers with bacterial inbibition type at normal atmospheric temperature was better in quality than those of common type. The water dispensers with bacterial inhibition type provided with hygienic licence should be better recommended to choice.

Objective To gain a better knowledge of the education for masters in clinical medicine (general practice) and provide a reference for the better exploration of the training mode of GP students.Methods 9 colleges and universities enrolling students for this program were selected with stratified sampling.A questionnaire was conducted in terms of admission,curriculum setting,clinical training,guidance and evaluation through officials in charge of graduate affairs from February to July in 2014.Descriptive analysis was performed to the investigation results,using SPSS 20.0 statistical software.Results A full-time undergraduate degree in clinical medicine was explicitly required in 88.9％ (8/9) of colleges and universities.The average total credits of the course were 23.7 and the average clinical training duration was 32.4 months.Tutor group was adopted in all colleges and universities.The assessment and evaluation of the GP masters was mainly composed of multiple forms of process assessment and final evaluation.Conclusion We suggest attaching more importance to the improvements of enrollment policy,curriculum system,clinical training,standardized training base construction,teaching staff,and evaluation system in order to explore GP training mode in accord with the law of general practice and suitable for China's national conditions.
