BACKGROUND: Vascular endothelial growth factor (VEGF) can promote angiogenesis, and has been extensively used in treatment of bone defect. However, few studies have addressed its isomer VEGF121. OBJECTIVE: To construct adenovirus vector carrying VEGF121-FLAG and humanized Renilla reniformis green fluorescent protein 1(hrGFP-1) and observe its expression in bone marrow stromal stem cells (BMSCs). METHODS: Using polymerase chain reaction technique, VEGF121 gene contained in the plasmid of pTG19T-VEGF121 was used to remove termination codon. NotI and Xho I restriction sites were added before and after gene sequence. Obtained gene subclone was moved onto pMD19-T plasmid. The pMD19-T-VEGF121 and pShuttle-CMV-IRES-hrGFP-1 plasmids underwent double enzymatic digestion. Small fragment and big fragment were retrieved utilizing gel. Subsequently, coupled reaction was conducted to complete the construction of shuttle plasmid. After measuring virus titer, BMSCs were transfected and the fluorescence intensity was observed under fluorescence microscope.RESULTS AND CONCLUSION: Recombinant adenovirus plasmid was successfully constructed by enzymatic digestion determination and gene sequence. Fluorescence microscope has shown that BMSCs transfected with recombinant adenovirus presented significantly green fluorescence expression. Thus, adenovirus vector carrying VEGF121-FLAG and hrGFP-1 gene can express in eukaryotic cells, which can be used for gene therapy for ischemic disease.

BACKGROUND: Hypoxia-inducible factor-1 (HIF-1) can regulate the co-expression of various genes, and can induce angiogenesis with integrated physiological function.OBJECTIVE: To construct a novel adenoviral eukaryotic expression vector that can co-express mutant hypoxia-inducible factor-1 alpha (HIF-1a) target protein and humanized Renilla reniformis green fluorescent protein (hrGFP) reporter molecule under normoxic conditions.METHODS: The human HIF-1α gene carried by target gene donor plasmid pCMV6-XL5-HIF1α was sequenced and the site of restriction enzyme in above gene was analyzed. Site-directed mutagenesis of three amino acids including the 402 location, the 564 location, and the 803 location in gene coding region in HIF-1α were performed by polymerase chain reaction and sequencing was also done for monitoring mutation. The HIF-1α gene mutated correctly (HIF-1αmu) was coupled to adenoviral shuttle vector pShuttle-CMV-IRES- hrGFP-1. The recombinant adenovirus shuttle vector carrying HIF-1αmu gene was transferred to BJ5183-AD-1 electroporation competent cells after sequencing identification and Pme I restriction enzyme linearization.HIF-1αmu and hrGFP gene as well as hemeo-expression elements of hrGFP gene were reconstructed into adenoviral genome plasmids using homologous recombination mechanism in bacterium. Recombinants were obtained by Pac I restriction enzyme digestion and sequencing identification.RESULTS AND CONCLUSION: Amino acids including the 402 location, the 564 location and the 803 location in gene coding region in HIF-1α had become alanine after site-directed mutagenesis. Recombinant adenoviral expressing vector was successful as confirmed by restriction enzyme digestion and sequencing. These findings demonstrate that a novel recombinant adenoviral mutant eukaryotic expression vector pAd-HIF1αmu-IRES-hrGFP-1 was successfully constructed.

OBJECTIVE:To explore the effects and safety of Hedan tablets on the levels of blood lipid,inflammatory factors and oxidative stress in coronary heart disease(CHD)patients with type 2 diabetes mellitus(DM2). METHODS:A total of 118 pa-tients diagnosed as CHD with DM2 were collected from our hospital during Jul. 2013-Nov. 2015,and then divided into observation group(63 cases)and control group(55 cases)according to random number table. Control group received conventional treatment such as controlling blood glucose,regulating blood lipid,vasodilator,anticoagulant. Observation group additionally received He-dan tablets 1.46 g before meal,tid,on the basis of control group. Both groups received treatment for 6 months. The levels of blood lipid (TC,TG,LDL-C,HDL-C),serum inflammatory factors (TNF-α ,IL-10,IL-6,hs-CRP) and oxidative stress indexes (MDA,SOD,NO)before and after treatment as well as the occurrence of ADR were compared in 2 groups. RESULTS:Before treatment,there was no statistical significance in levels of blood lipid,serum inflammatory factors or oxidative stress indexes be-tween 2 groups(P>0.05). After treatment,the serum levels of TC,TG,LDL-C,TNF-α,IL-6,hs-CRP and MDA in 2 groups were decreased significantly,while those of IL-10,SOD and NO were increased significantly;the observation group was signifi-cantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Hedan tablets can effectively improve the level of blood lipid,reduce the lev-el of inflammatory factors,relieve inflammatory injury,reduce the level of oxygen free radical,strengthen antioxidant capacity and lighten oxidative stress injury with good safety.
