Purpose To analyze the correlation of right subclavian artery ultrasound and individual blood lipid level with coronary atherosclerosis (CA) using carotid ultrasound as control so as to explore the clinical value of them in predicting CA.Materials and Methods Coronary CT angiography (CCTA) and right subclavian artery/neck vessel ultrasound in 55 patients were retrospectively analyzed.Gensini score was used to calculate the degree of coronary artery lesions.According to the result of CCTA,patients were divided into normal group,mild coronary atherosclerosis group,severe coronary artery stenosis group.The intina-media thickness (IMT) at the origin of right subclavian artery and carotid artery bifurcation on ultrasound was measured to evaluate carotid lesions.The correlation between the IMT and Gensini score of coronary artery was analyzed.The blood lipid levels of the 3 groups were analyzed,and the efficacy of right subclavian artery,carotid artery ultrasound and blood lipid in predicting CA was evaluated.Results ① The IMT at right subclavian artery and carotid artery bifurcation were positively correlated with Gensini score,and the former had higher correlation than the latter (r=0.636,r=0.462,P<0.01);the prediction efficacy of the IMT at right subclavian artery was slightly higher than that at carotid artery bifurcation (with sensitivity and specificity of 78.3%,64.5%,and 77.5%,60.0% respectively).② Compared with normal control group,the levels of low-density lipoprotein cholesterol,triglycerides,total cholesterol were higher,but the level of highdensity lipoprotein cholesterol (HDL-C) was lower in mild coronary atherosclerosis and severe coronary artery stenosis group,and the difference between the severe coronary artery stenosis group and normal groups was bigger,among which the level of triglycerides had the largest difference among the three groups with no statistical significance (P>0.05).The HDL-C had a more significant correlation with Gensini score than other index of blood lipid (r=-0.151).③ The combination of IMT and HDL-C had a sensitivity of 81.0% and specificity of 66.7% in predicting CA,which were higher than that of each individual index (with sensitivity of 78.3%,64.5% and specificity of 64.3%,55.5%respectively).Conclusion The IMT at right subclavian artery has a better predictive value in determining the degree of coronary artery lesions than that at carotid artery bifurcation.The combined application of blood lipid levels and the IMT at right subclavian artery can improve the sensitivity and specificity of predicting CA.

Objective To determine the correlation between mouse maerophage metalloelastase (MME)and vascular endothelial growth factor(VEGF)expression involved in angiogenesis of colon cancer.Methods A eDNA fragment coding for domainsⅠandⅡof MME was transfected into murine CT-26 colon cancer cells that were MME deficient.The enzymatic activity of recombinant MME was confirmed by cleavage of native substrate in vitro.An orthotopic implantation model was established by using MME-transfected cells and control cells.Tumor samples were subjected to in situ hybridization (ISH)and immunohistochemical staining(IHC)to detect expressions of MME and VEGF.The microvessel counting was used to assess angiogenesis of murine colon tumors.Results It was demon- strated that the tumor growth was significantly inhibited in MME-transfected group compared with pcDNA3.1 transfected and nontransfected groups(P<0.001).It was also found that,compared with pcDNA3.1-transfected and nontransfected groups,the microvessel formation in MME transfected group was significantly reduced(P<0.001).The expression of VEGF mRNA and protein was significantly lower in MME-transfected group than those in the controls,as demonstrated by ISH(MME-transfected group versus pcDNAa.1-transfected group,P=0.028;and versus nontransfected group,P=0.003) and by IHC(MME-transfected group versus pcDNA3.1-transfected group,P=0.025;and versus non- transfected group,P=0.008).Conclusions The MME gene transfected into murine colon cancer cells can effectively suppress the growth of orthotopic tumors by inhibition of vaseularity.Both MME and VEGF gene expression is highly associated with the vascularity of tumors,which may depend on a hal- ance between MME and VEGF expression.

In order to construct a prokaryotic expression vector of human receptor syt II N-fragment and to express recombinant MBP-Syt fusion protein in E.coli and to purify and identify its activity. According to codon preference of E.coli, a DNA fragment encoding human syt II N-fragment was synthesized, and then cloned into prokaryotic vector pMAL-c2x for sequencing. Then the recombinant plasmid pMAL-Syt was introduced into E.coli ER2566 by transformation for expression and the obtained engineered bacteria were induced by IPTG. The fusion protein was purified by amylose resin affinity chromatography and identified by SDS-PAGE and Western blot. The binding activity of the protein was determined by ELISA. It is concluded that MBP-Syt protein is of good binding activity.
