ABSTRACT
Objective: To explore the effects of research-oriented teaching on the basis of team in stem cell-basics and clinics for graduates. Methods: Forty-one graduates in Institute of Basic Medical Sciences, Chinese Academy of Medical Sciences who participated in the study of stem cell-basics and clinics were consecutively selected. Researchoriented teaching was introduced after traditional lecture-based teaching, and the evaluations were taken at the end, including teaching evaluation, student satisfaction with the study, and assessment of creative ability and project design. Results: As shown in the questionnaire survey, the learning interest and the craving for knowledge, the creative ability and the level of project design were effectively improved, the scientific research quality was well trained. Conclusion: The research-oriented teaching method can effectively improve graduates' comprehensive ability of self-learning and the creative ability. It is an effective new approach for teaching which is worthy of promotion in graduates' teaching.
ABSTRACT
Objective To investigate the hepatoprotective effect of silybin-phosphatidylcholine complex(SPC) in sepsis rats.Me-(thods) Fifty Wistar immature rats were randomly divided into 3 groups:normal control(10 cases),septic group(30 cases) and interfe-(rence) group(10 cases).In septic group and interference group,rats were treated by cecal ligation and puncture(CLP).Meanwhile,the interference group was given SPC before 2 hours of CLP and after 2 hours of CLP.Blood of rats was taken from all groups to determine the levels of serum tumor necrosis factor-?(TNF-?),interleukin-1(IL-1),alanine aminotransferase(ALT) and aspartate aminotransferase(AST) at varying intervals.Results The levels of serum TNF-?,IL-1,ALT and AST after CLP were significantly elevated in septic group compared with the normal control group(P
ABSTRACT
We have constituted a mouse model for fetal blood transplantation (FBT) to cross over major histocompatibility complex (MHC) without causing serious GVHD. It seems that full matching at the MHC appears not necessary for FBT, while the nucleated cell dose is critical. Two fetal blood units were combined from different donors to increase the stem/progenitor cell dose so as to explore the possibility of MHC-mismatched allogeneic transplantation. 26 out of 40 mice in mixed FBT group survived in the observation period of 60 days after transplantation without obvious GVHD. Double chimerism was demonstrated by PCR and flow cytometric analysis; and skin transplantation test proved the induction of donor specific immune tolerance. Our data suggest that two MHC-mismatched allogeneic donor fetal blood units could simultaneously engraft and reconstitute immune and hematopoietic system in a mouse model. The result may be beneficial for the expansion of cord blood application and enables more patients to share the advantages of cord blood transplantation.
