Eight-year program of clinical medicine is the necessary trend of economic rapid development.Based on the introduction of research on and practice of eight-year medical education in The Third Military Medical University,the article makes a consideration on pre-school medical education,bilingual teaching,dual-tutorial system and the requirement of thesis.In addition,it puts forward some problems needing further study.

As the understanding of science creativity becomes more profound,people find out that organizational barriers are greatly deterring and discouraging the advent and development of science creativity.Drawing upon the Situation Theory of Creativity and earlier researches,we identified crucial organizational factors that imposed influence on science creativity and considered those factors as gauge to reflect on the current practice of science research management in China.The findings show that science research funding mode,collaboration and communication opportunities and accesses,science researchers' career development and evaluation system,research group leadership,size and diversity of research teams are all key components of the organizational barriers that failed to nurture and spur Chinese researchers to solve long existed and challenging problems with original approaches and creative thinking.Therefore,innovations of science research management are necessary and urgent.

Objective To explore the changes of appendicular skeletal muscle (ASM) in peritoneal dialysis (PD) patients, and to analyze the relationship between ASM changes and dietary intake.Methods One hundred and fourteen PD patients were enrolled in Department of Nephrology, Peking University Third Hospital using convenience sampling.At baseline, and 6 and 12 months after PD, bioelectrical impedance analysis was used to assess the body weight, total muscle mass, and ASM of these patients, and three-day food record was used to assess the dietary intake.Demographics and clinical data were also collected at baseline.Results Compared with baseline, the patients' ASM at 12 months after PD decreased significantly [(19.27 ± 5.59) kg vs.(25.65 ±6.09) kg, P =0.000], the dietary protein intake and energy intake decreased significantly [(0.85 ± 0.21) g/(kg · d) vs.(0.90 ± 0.27) g/(kg · d), P =0.038;(128.37 ± 26.67) kJ/(kg· d)vs.(137.27 ±29.23) kJ/(kg· d), P=0.001].The patients were divided into three groups based on ASM loss, the mean dietary protein intake of the top-loss 1/3 group was statistically lower than that of the bottom-loss 1/3 group [(0.82 ± 0.18) g/(kg · d) vs.(0.91 ± 0.20) g/(kg · d), P =0.021].Conclusions With the continuation of PD, ASM of patients may decrease, which is likely to be mainly related to deficiency in protein and energy intakes.Dietary management should be strengthened in PD patients to alleviate the loss of ASM.

Developing the clinical thinking ability and therefore improving the clinical practice ca-pacity are the core of the quality-oriented education and in the current medical education reforms. The rea-sons for retarding the development of clinical thinking ability in dental clinical probation were herein dis-cussed. According to the similarity between mind mapping and clinical thinking, drawing mind map was used in the creation of the clinical knowledge system; various teaching techniques were used and classical clinical cases were shown; role playing as dentist and patient was used to mimic the clinical circumstance;dentist-patient communication was emphasized and methods to evaluate the clinical thinking ability were also developed. These strategies effectively developed the clinical thinking ability of the dental students.

Medical students face higher levels of stress compared to the general population. Statistical analyses of questionnaire surveys were made to compare the teaching effect between traditional teaching and PBL.The results indicate that the PBL teaching is more conducive to students to relief from the course-related stress in medical colleges.

The Third Military Medical University promotes the scientific research ability of the eight-year clinical medicine students through accurately fixing cultivation objectives,reasonably arranging teaching,implementing supervisor group for many-to-one teaching,carrying out plentiful innovative re-search projects,establishing reading system of scientific research papers,setting up scientific research innovation courses and setting up the credit system for innovative education. Eight-year program is signifi-cantly better than the five-year program in cultivating abilities of problem-discovering,researching and thesis writing.

Objective To explore clinical distribution characteristics of carbapenem-resistant Klebsiella pneumoniae (CRKP), analyze enzyme production of strains and verify the in vitro antimicrobial activity of tigecycline.Methods Antimicrobial susceptibility testing results of 53 strains of CRKP isolated from clinical specimens of patients in a hospital from January to December 2015 were analyzed, carbapenemase production of target strains was detected by modified Hodge test, metallo-β-lactamase was detected by EDTA synergy test, minimum inhibitory concentration(MIC) of tigecycline susceptibility testing result detected by instrument was confirmed by MIC test strip(MTS method).Results 53 CRKP strains were mainly isolated from patients in intensive care unit (n=14, 26.42％) and burn unit(n=13, 24.53％);sputum(n=23, 43.40％) and wound secretion(n=15, 28.30％) were the main specimen sources;isolation rate of CRKB was highest in the elderly≥60 years old, 35 strains(66.04％)of CRKP were isolated.CRKP was most sensitive to tigecycline(96.2％).The modified Hodge test showed that 48 strains(90.6％) produced carbapenemases and 15 strains produced metallo-β-lactamase.MICs of tigecycline-resistant strains detected by instrument were all confirmed as susceptibility by MTS.Conclusion CRKP mainly produce carbapenems in this hospital, some strains can produce two types of different β-lactamases;antimicrobial susceptibility testing showed that tigecycline has good antimicrobial activity against CRKP, tigecycline-resistant strains detected by instrument must be confirmed by MTS method.

Rapid development in medical technology has posed new challenges to higher medical education,especially to education of eight-year program students.How to survive the challenges has thus become a question for medical institutions.By analyzing the features of medical development and the new demand of medical education,we proposed the following innovations for education in eight-year program.It should emphasize combination of different disciplines and construction of integrated medical course system.Research on translational medicine should be conducted,and cooperation between institutions should be promoted.

Objective To evaluate the effect of health belief model combined with PDCA circulation in preventing DVT of patients undergoing total hip replacement and total knee replacement.Methods Patients who met our inclusion criteria were randomly divided into the intervention group and the control group with 45 cases in each group.The patients in the control group received routine health education.In addition,the intervention group received health education based on health belief model combined with PDCA circulation besides the routine.The intervention results were compared between the two groups.Results The patients' mastery of DVT disease related knowledge,health belief and the implementation of preventive measures in the intervention group were significantly better than those of the control group one week after surgery.The score of the health belief,perceived susceptibility,perceived severity,perceived benefits of action and serf-efficacy in the intervention group were significantly superior to those of the control group.1 patient appeared blood stasis in the intervention group.However,in the control group,there were 2 patients with DVT and 6 patients with blood stasis.The effect of preventive measures in the intervention group was better than the control group.Conclusions Health education based on health belief model combined with PDCA circulation could effectively enhanced the patients' DVT disease related knowledge,health belief and the implementation of preventive measures,thereby reduce the risk of DVT and improve the patients' quality of life.
