Reteplase fusion protein：expression, purification and the effect of chaperones on its renaturation / 安徽医科大学学报

Objective To construct the prokaryotic expression system of reteplase fusion protein and research the effect of chaperones on its renaturation. Methods Inserted the reteplase gene into the prokaryotie expression vector PET32a and then expressed it by the induction of IPTG in E. coli BL21. Researched the effect of chaperones on the renaturation of fusion protein by adding different chaperones. Results The analysis of SDS-PAGE and Western blot indicated that reteplase fusion protein was expressed correctly. Chaperones DsbA,pKJE7,pTf16 had the conspicu-ous effect on the renaturation of fusion protein. The result of activity assay indicated that the refolded reteplase fu-sion protein had fibrinolytic activity. Conclusion Chaperones can promote renaturation of reteplase fusion protein.

Necessity of Increasing the Teaching Hours of Anesthesiology Course for Clinical Medicine Undergraduate / 中华医学教育探索杂志

The present higher education curriculum gets adrift from the present modern anesthesiology development seriously.Clinical young doctors generally lack anaesthesia knowledge and first aid skill.It's impossible for them to gain anesthesiology knowledge and the skill through continuing medical education.We should adjust education curriculum to increase the teaching hours of anesthesiology course for clinical medicine undergraduate.
