Exploration and reflection on theeffect of formative assessment in medical immunology teaching / 中华医学教育探索杂志

To achieve better results of the goal of training students' abilities in medical education,formative assessment has been implemented in medical immunology teaching for grade 2014 clinical medicine students.The evaluation indexes of medical immunology teaching have been constructed.Formative assessment has been implemented in classroom teaching,self-learning and group discussion,experimental teaching and network exams by following the principles of feedback,guidance and encouragement.Compared with summative assessment,formative assessment can dynamically reflect the learning progress of immunology and improve the learning effect.The deficiencies andpuzzlesin implementing the formative assessment have also been rethought and discussed deeply.

Expressions of Let-7 in Normal Breast Tissue and Breast Cancer Tissue / 昆明医科大学学报

Objective To study the expression characteristics of Let-7 genes in breast cancer.Methods Twenty-eight patients with breast cancer were randomly selected,and their cancer tissue and adjacent normal tissue were collected.TRIzol was used to extract the total RNA and real-time quantitative PCR was used to detect the relative gene expression levels.Results The expression of precursor Let-7 in cancer tissue was (9.65 ± 2.31),which was lower than that in normal tissue (10.05 ± 2.81),P =0.048.Precursor Let-7 had dependence relationship with the long menstruation (b =0.816,P =0.029).The menarche age showed a positive correlation with precursor Let-7 in normal tissue (r =0.502,P =0.048) and a negative correlation in cancer tissue (r =-0.484,P =0.049) Conclusions The expression of precursor Let-7 in cancer tissue is lower than that in normal tissue.The period of menstruation is a protective factor to breast cancer.

Study of Medical Immunological Bilingual Teaching / 中华医学教育探索杂志

The appliance of bilingual teaching of Medical Immunology offers an effective means of mastery and communication of the medical essential subject.This study has tried the bilingual teaching of medical immunology for clinical,dentistry and phylaxiology specialty students,discussed the model of bilingual teaching,investigated the teaching effect,analyzed and summarized the teaching experience.After the practice of bilingual teaching,we found that the feasible method of bilingual teaching to apply Chinese as the primary language and pervade English into the medical immunology course.
