1.CLINICAL OBSERVATION ON AHALYSANTINFARC-TASE TREATMENT FOR SCLERODERMA
Journal of Chongqing Medical University 1986;0(04):-
Ahalysantinfarctasum treatment for scleroderma has not been reported in the literature.This paper reports 10 cases treated with ahalysantinfarctase.7 cases were systematic scleroderma and the other 3 localized type.The result of analysis showed that this drug has certain effect for scleroderma

Objective To prepare the flurbiprofen orally disintegrating tablets and establish the procedures of controlling the quality.Methods Flurbiprofen orally disintegrating tablets was prepared by wet granulation and it content was determined by HPLC.Results The obtained tablets were fine in the shape and smooth in the surface.Their hardness was 2 kg,the disintegrating time was about 30 s.The linear correlation was in a range of 1.0-10.0 ?g/ml,r=0.999 9.The average recovery was 99.32%,RSD=1.09%(n=7).Conclusion Our methods of flurbiprofen orally disintegrating tablets are simple and feasible in preparation and quality control.

Objective To establish the A549 cell line with stable expression of HIF1α by using lentiviral vector system.Methods Primers were designed and synthesized with human HIF1α gene coding sequence by the National Center of Biotechnogical Information(NCBI) as the template.HIF1α was amplified by PCR.The HIF1α fragment recycled by enzyme digestion was recombined with prepared lentiviral vector HBLV-RFP-Puro.The recombinant plasmid was identified by PCR and gene sequencing.The recombinant plasmid and the auxiliary plasmid were co-transfect into 293T cell.After filtration and concentration of packaged virus,the viral titer was detected by using the dilution counting method.The prepared lentivirus was infected A549 cells.The drug screening was adopted to stabilize the transfected cell line.The transfection effect was detected and observed by fluorescence microscope and Western blotting.Results The HIF1α fragment amplified by PCR was successfully verified and the recombinant plasmid was successfully constructed by PCR and gene sequencing identification.High-titer LV-HIF1α was obtained by successful package.After LV-HIF1α infecting A549 cells,the cells showed the red fluorescence by fluorescence microscope.The expression level of HIF1α in the LV-HIF1α group was significant higher than that in the control group by Western blot.Conclusion The 549 cell line with HIF1α stable expression mediated by lentivirus is constructed successfully.
