Application of PBL teaching model in experimental teaching of clinical hematologic laboratory / 中华医学教育探索杂志

We use PBL teaching mode in experimental teaching of clinical hematologic laboratory.By this method,the knowledge can be mastered by the students more efficiently and the analyzing ability was also improved.We hope that these experiences can be useful in our country's clinical laboratory teaching.

Cloning of CGI-100 gene and reconstruction of its eukaryotic expressive vector / 重庆医科大学学报

Objective:To clone human CGI-100 gene and reconstruct its eukaryotic expressive vector for further investigation.Methods:The full coding domain sequence of human CGI-100 gene was cloned from human leukemic K562 cells with RT-PCR and was sub-cloned into pMD18-T Simple vector.After confirmed by DNA sequencing,the targeted DNA fragment,digested with BamHⅠand PstⅠ,was directionally cloned into eukaryotic expressive plasmid pIRES2-EGFP,then,the reconstructed plasmid was identified with enzyme digestion,PCR and sequencing.Results:It was demonstrated that the full coding domain sequence of human CGI-100 gene was accurately cloned into digestion sites between BamHⅠand PstⅠin pIRES2-EGFP without mutation and transposition.Conclusion:The reconstruction and verifying of eukaryotic expressive plasmid containing CGI-100 gene are successful,which establishes the foundation of further investigation.
