4.A preliminary study of improving the System B root canal filling technique
Journal of Practical Stomatology 2001;0(03):-
Objective:To combine the cold lateral condensation with System B root canal filling techniques in order to increase the amount of gutta-percha to fit different canal that could improve percentage of gutta-percha-filled area(PGFA)and decrease the probability of apical extrusion. Methods: Two groups of extracted human canines (total 80) were prepared by modified double-flared technique and filled with gutta-percha by System B technique and the combined technique respectively. The overfilling samples were collected. A horizontal section was cut 1.5 mm from the apical foramen of each tooth. The cross-sectional area of the canal and the gutta-percha was measured using an image-analysis program. The PGFA was then calculated. Results:Overfilling rate in the combined technique group was significantly lower than that of the control group (P
5.Observation the effect of Pre hospital thrombolysis on the emergency treatment measures in treatment of ST segment elevation acute myocardial infarction
Chinese Journal of Primary Medicine and Pharmacy 2014;(24):3730-3731,3732
Objective To explore curative effect of emergency treatment measures on ST segment elevation acute myocardial infarction.Methods A total of 142 cases of acute ST segment elevation myocardial infarction were received the thrombolytic therapy,percutaneous coronary intervention ( PCI) ,emergency coronary artery bypass graft-ing treatment.Results A total of 20 cases were received pre hospital thrombolysis,percutaneous coronary interven-tion ( PCI) therapy in 86 cases,32 cases of pre hospital thrombolysis combined with emergency PCI operation,4 cases of emergency coronary artery bypass graft surgery.The one year survival rates were 94.7%, 98.8%, 96.8%, 100.0%,respectively.Conclusion The prehospital diagnosis of acute myocardial infarction with ST segment eleva-tion is helpful for reducing recanalization time,and initialing the hospital treatment,so as to effectively simprove cardi-ac function and postoperative survival rate,which is worthy of clinical reference.
6.An update of RNA interference in tumor therapy
Journal of Medical Postgraduates 2003;0(08):-
Tumor is a reciprocity result of various genes and factors,and its incidence and mortality remain high.Such traditional strategies as surgery,radiotherapy and chemotherapy cannot completely restrain and reverse the growth of tumor cells.So,new and more effective therapeutic methods are being expected.This article updates the development of RNA interfering(RANi) technique in the targeting therapy of the tumor gene.

Objective:To study characters of the location in cells and binding activity of chicken Ii and B-L gene expressed products.Methods:The cloned gene segments of chicken Ii,B-LA and B-LB were respectively inserted into prokaryotic or eukaryotic expression plasmids,and then these recombinant plasmids were respectively alone transfected or cotransfected into engineering bacteria, Rosetta(DE3) or 293T cells.All of the recombinant bacteria were induced to express and their products then were renatured.The singly expressed products were detected to their immunogenicity with Western blot, and the co-expressed products were tested their binding with pull-down method and ( SDS-) PAGE.Results:First six of prokaryotic and eukaryotic recombinant expression plasmids were con-structed.The eukaryotic expressed products of Ii, B-LA and B-LB genes located in cellular plasma membrane.The single protein molecules were achieved from prokaryotic expressed products, which were renatured and purified with a Ni-column respectively.Secondly the prokaryotic expression Ii,B-LA and B-LB molecules could respectively induce mouse to product specific anti-bodies, which could recognize the corresponding products in eukaryotic expression.This indicated that they retained their antigenicity.Finally with pull-down from the products in co-expression in engineering bacteria and renaturation the Ii/B-LA or Ii/B-LB complexes were purified and the Ii,B-LA or B-LB monomers were dissociated from these complexes after a SDS treatment.Conclusion:The prokaryotic or eukaryotic expressed products of chicken Ii and B-L genes could retain their antigenicity,and chicken Ii could bind B-L molecules after prokaryotic coexpression and renaturation.These results provide a useful method to study the relation between Ii and MHC molecules.
