Research progress in Guanxin Tongluo capsule for the treatment of coronary heart disease / 中国基层医药

Guanxin Tongluo capsule is a compound traditional Chinese medicine preparation for the treatment of coronary heart disease. The underlying mechanism may be related to expanding coronary artery, increasing coronary artery blood flow, reducing myocardial oxygen consumption, and decreasing whole blood viscosity, plasma viscosity, and hematocrit. This paper reviews the clinical research progress of Guanxin Tongluo capsule in the treatment of coronary heart disease from the aspects of etiology, pathogenesis, pharmacological research, and clinical research, providing evidence for scientific research and clinical application of Guanxin Tongluo capsule.

Construction and target gene expression of recombinant adenovirus vectors containing vascular endothelial growth factor 165 and angiopoietin-1 / 中国矫形外科杂志

[Objective]To construct the recombinant adenovirus vector co-expressing human vascular endothelial growth factor 165(VEGF165) and angiogenin-1(Ang-1),and to observe the expression of target gene after transfection.[Method]Molecular biologic techniques were used to clone the genes of VEGF165 and Ang-1,and PCR was used to amplify the DNA sequence of IRES(internal ribozyme entry site) from pIRES2-EGFP.The genes of VEGF165,IRES and Ang-1 were subcloned to pTrack-CMV one by one to get the plasmid named pTrack-CMV-VIA,which contained all the three genes.The linearized shuttle plasmid was cotransformed into BJ5183 bacteria with backbone vector AdEasy-1.Further the recombinant plasmid was packaged and amplified in QBI-293A cells after Pac I digestion to get adenovirus vector pAd-VIA.The expression of the gene of interests was evaluated by fluorescence microscopic analysis of GFP expression and enzyme linked immunosorbent assay(ELISA).[Result]The recombinant adenovirus plasmid was consistent with that shown by sequencing and restriction endonucleases digestion.The recombinant pAd-VIA vector was packaged and amplified successfully in QBI-293A cells.The titer was 2?1010 PFU/ml after amplifying.High positive GFP was expressed in the field through fluorescence microscopy after being transfected by recombinant pAd-VIA.ELISA indicated the expression of the target genes.The difference between the tansfected and non-transfected group was significant(P
