Objective To strengthen the ability of clinical thinking and the ability to solve practical clinical problems for medical students.Methods Medical undergraduates studying in affiliated hospitals of Tongji university from 2005 to 2010 were enrolled The clinical thinking training and assessment in clinical teaching were enhanced by introducing problem-based learning,case-based learning and by strengthening the role of interns in clinical work and emphasizing clinical thinking ability assessment during various kinds of clinical skills examinations.Meanwhile,the teaching management and supervision were improved.The awareness and ability of clinical teachers to train students′ clinical thinking were aroused and cultivated through teaching staff training so as to ensure that clinical thinking training and assessment were involved in the whole process of clinical teaching.Results The students' abilities of self-study,scientific thinking and oral expression were improved.The passing rates of our graduates in national general medical practitioner test were increasing yearly from 2006 to 2008.Conclusion Strengthening clinical thinking ability training during clinical teaching plays an active role in improving clinical skills in medical students.

In order to train the clinical ophthalmic seven-year students to further comprehend their professional knowledge and further stimulate their imagination and creation ability, we developed several steps to promote these students' patent designing ability. These steps include: trained targets selection, theoretical knowledge training, clinical practice training, comprehensive quality control, et al. In the implementation of the concrete steps, we put emphasis on the elements such as step by step training, the high quality computer assisted mapping and the internationally compatible contents, et al., and encouraged the students to propose the assumption of solving the problems in the clinical and sci-entific research. And the stimulation mechanism and medical humanity were infiltrated all the while.

Post competency-based medical education complies to the development and philosophy of modern medicine. This paper completely illustrates how to construct a scientific and diversified assessment evaluation system guided by post competency for medical students which combines formative assessment and summative assessment. Through the objective measurement and timely feedback of various abilities of medical students, the closed-loop feedback system of assessment and evaluation can be constructed to guide the exploration and practice of teaching process in reverse.

Objective To study the effect of rice oil on secretory immunoglobulin A (sIgA) content in feces and disease outcome in children with acute diarrhea.Methods We selected 180 children with acute diarrhea hospitalized in Tianjin Children's Hospital during the period from January 2013 to October 2014.They were randomly divided with a random number table into rice oil group,montmorillonite powder group and control group (all n =60).The effect of treatment,duration before subsiding of diarrhea and vomit,length of hospital stay and sIgA content in feces before and after treatment were analyzed.Results The total effective rates in the rice oil group and the montmorillonite powder group (93.3％,96.7％) were significantly higher than that in the control group (76.7％,P =0.011,P =0.001).Length of hospital stay,duration before subsiding of diarrhea and vomit in the rice oil group and the montmorillonite powder group were significantly shorter than those in the control group[(5.6±1.4) d,(5.7±1.6) d vs.(6.9±1.8) d;(3.7±0.9) d,(3.5±0.9) d vs.(5.4±1.2) d;(2.8 ± 0.6) d,(3.2 ± 0.8) d vs.(5.1 ± 0.8) d;all P =0.000].The total effective rates,length of hospital stay,duration before subsiding of diarrhea showed no statistically significant differences between the rice oil group and the montmorillonite powder group (P =0.402,0.716,0.226),but the duration before subsiding of vomit in the rice oil group was significantly shorter than that in the montmorillonite powder group (P =0.016).Before treatment,the sIgA contents in feces in the control group,the montmorillonite powder group,the rice oil group were 0.527 ± 0.133,0.487 ± 0.109,0.534 ± 0.150,with no significant difference (P ＞ 0.05).Two days after treatment,sIgA contents in the rice oil group and the montmorillonite powder group (0.669 ±0.176,0.612 ± 0.161) were significantly higher than in the control group (0.541 ±0.149,P =0.000,0.014).There was no significant difference between the montmorillonite powder group and the rice oil group (P =0.067).Four days after treatment,sIgA content in the montmorillonite powder group (1.981 ±0.462) was significantly higher than in the control group (1.762 ±0.378,P =0.005),while sIgA content in the rice oil group (2.331 ± 0.494) was significantly higher than in the other 2 groups (P =0.000).Compared with the levels before treatment,sIgA content 2 days after treatment was not significantly changed in the control group (P =0.295),but was significantly elevated in the montmorillonite powder group and the rice oil group (both P =0.000).sIgA contents of all the three groups 4 days after treatment were significantly higher than the contents 2 days after treatment (all P =0.000).Conclusion The effect of rice oil on acute diarrhea in children is as same as that of montmorillonite powder,and may be better in mitigating vomit and promoting the secretion of intestinal sIgA.
