ABSTRACT
[Absrtact] Objective To investigate the effect of anatomic quantitative target evaluation of class-room teaching on students' professional knowledge learning ability. Methods Twenty-five international students of 6-year program of grade 2013 were chosen as the experimental group, while twenty-seven Chinese students coming from the same class of grade 2013 and fifteen international students of 6-year program of grade 2012 were chosen as two control groups; quantitative and non-quantitative evaluation were imple-mented respectively by classroom questions and answers; teaching effects were evaluated by scales in the separation of teaching and examination, by records of answers for in-class questions and by questionnaire survey; SPSS 20.0 was used to make statistical analysis, one-way ANOVA and Kruskal Wallis test to com-pare the scores of three groups of students, P Quantitative evaluation of teaching objectives in anatomy class can improve the learning attitude of foreign students and enhance their academic ability.
ABSTRACT
Objective To explore suitable anatomy for teaching methods for international medical students from multiple sources. Methods Thirteen international medical students of 6-year-programme (grade 2011) and 19 Chinese medical students of five-year-programme were taught with Chinese system anatomy(module) textbooks and Chinese-English bilingual textbook(as reference) by three-step bilingual anatomy teaching method , which includes previewing anatomical vocabulary , teaching Chinese and foreign students in the same class. Teaching effect was international tested by scale separating teaching and examing and questionnaire survey. SPSS 10.0 was used to do statistical analysis and t test was used to compare the score of Chinese medical students and international med-ical students. P<0.05 students for statistic difference. Results Average test scores of international and Chinese students in the same class were 86.2 and 88.1 respectively, with no significant difference (P﹥0.05). 92.3%(12/13) international students were satisfied with this teaching method and the same class teaching for Chinese and international students . Conclusions Three-step bilingual anatomy teaching method in the same class may be more suitable for international students from multiple sources and this teaching method is worthy of further study and practice.
ABSTRACT
At present, there are 8 sources of neural stem calls (NSCs), such as the early embryo, umbilical cord blood, brain tissue of adults and bone marrow, which are used for experiments. Four methods are also provided to isolate NSCs, for example, the serial passage and the gene transduction. Most of the hotspots at home and abroad are on the modulation of NSC transplantation in vivo, to make it proliferate and differentiate in hand. Most findings are achieved through experiments on rodents, no matter in vitro or vivo, which indicate that the proliferation and differentiation of NSCs can be affected by a variety of biological factors and drugs. Even more, the effects are multiple according to the factors and drugs of different kinds and the same kind of different concentrations, even the same factor would have different roles in different process of the culture of NSCs. The survival of NSCs during transplantation can also be affected by local microenvironment. Neither the NSC endogenous nor exogenous treatment is efficient. Furthermore, the body also rejects the exogenous NSCs. Taken together, it is tough for us to conclude that a factor does have some effects on the NSCs. Moreover, there are still a series of key problems unveiled clinically, such as how to perfect transplantation and whether to choose exogenous or endogenous NSCa for transplantation.
