Objective To investigate the effects and the possible mechanism of insulin like growth factor-1 ( IGF1 ) on proliferation and migration of human umbilical vein endothelial cells ( HUVEC) in high glucose. Methods Cultured HUVEC were divided into 5 groups( control group, high glucose group, hypertonic group, high glucose+IGF 1 group, high glucose+IGF1+ AZD5363 group) . The proliferation was detected by methyl thiazolyl tetrazolium ( MTT) , the migration was detected by transwellchamber. The mRNA expressions of serine/threonine kinase( Akt) and FoxO1 were detected by real-time PCR. The protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were detec-ted by immunohistochemisty. Results Compared with the control group, the rate of cell survival in high glucose group decreased significantly(P<0. 05), the transitional was decreased significantly(P<0. 05), the mRNA ex-pression of FoxO1 was increased significantly( P<0. 05 ) , the protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were increased. Compared with high glucose group, the cell survival rate and migration rate in high glucose+IGF1 group were increased significantly, the mRNA expression of FoxO1 was decreased significantly(P<0. 05), the protein expressions of FoxO1/p-FoxO1 and Akt/p-Akt were decreased. Compared with high glucose group, the cell survival rate and migration rate in high glucose+IGF1+AZD5363 group had no significant difference, the mR-NA expression of FoxO1 was decreased significantly ( P<0. 05 ) , the protein expressions of FoxO1/p-FoxO1 had no significant difference. The mRNA expression of Akt in five groups had no significant difference. Conclusion IGF1 can improve the proliferation and migration of endothelial cell in high glucose. It shows that IGF1 acts through Akt to promote FoxO1 phosphorylation.

Objective To investigate the correlation of the single nucleotide polymorphism (SNP) of PON1 (Paraoxonase-1) gene rs854572 to the occurrence of clopidogrel resistance (CR). Methods A case-control method was employed in present study. A total of 850 hospitalized patients with coronary artery diseases (CAD) in General Hospital of Shenyang Command were enrolled. The residual platelet aggregation rate (RPA) induced by 20μmol/L of adenosine diphosphate (ADP) was detected by optical nephelometry, and RPA≥70% was defined as CR. Accordingly, all the enrolled 850 patients were then divided into CR group (n=215) and non-CR (NCR) group (n=635). Polymerase chain reaction (PCR) and pyrophosphate sequencing were executed to determine the genotypes and the allele frequencies of PON1 gene rs854572. Results The genotype frequencies in rs854572 of PON1 gene conformed well to the Hardy-Weinberg equilibrium in both CR group and NCR group. Three frequencies of genotype CC, CG and GG were 23.7%, 49.3%, 27.0% in CR group, and 24.1%, 50.2%, 25.7% in NCR groups, respectively. No significant difference in genotype and allele frequency existed between CR group and NCR group (P=0.93 and 0.76, respectively). Logistic regression analysis revealed that no correlation between rs854572 SNP of PON1 gene and the formation of CR in patients with CAD after adjustment of correspondent factors including age, gender, body mess index, smoking, hypertension, diabetes mellitus and hyperlipidemia. Conclusions It is considered that no correlation exists between PON1 gene rs854572 polymorphism and clopidogrel resistance in patients with coronary heart disease.

BACKGROUND:Studies have confirmed that nicotine affects the activity of osteoblasts, osteoclasts, fibroblasts and erythrocytes.
OBJECTIVE:To study the nicotine effects on osseointegration and the expression of osteoprotegerin and bone morphogenetic protein 2 after implantation of dental implants with surface treatment by sandblasting or acid etching.
METHODS:Twenty-four Sprague-Dawley rats were randomly assigned to two groups and received daily injections for 2 weeks as folows: Nicotine 2 mg/kg twice for experimental group, saline solution for control group. Then the titanium implants with surface sandblasting or acid etching were implanted into the tibiae folowed by continuous nicotine or normal saline injection. At weeks 2 and 4 after implantation, the implants and surrounding bone tissue were prepared for CT, X-ray and hematoxylin-eosin staining examinations to evaluate bone healing and expression levels of bone-related genes were measured by quantitative RT-PCR.
RESULTS AND CONCLUSION: Compared with the control groups, the degree of osseointegration and the expression of osteoprotegerin and bone morphogenetic protein 2 in the experimental groups were decreased significantly (P < 0.05), except that the expression of bone morphogenetic protein 2 in the experimental group with acid etching was not significantly reduced. In addition, the expression of bone morphogenetic protein 2 in the experimental group with acid etching was higher than that in the experimental group with sandblasting at 2 weeks after implantation (P < 0.05). The X-ray and CT show that the quantities of new generation bone and the degree of bone mineralization of the sandblasting group were significant lower than those of the acid etching group under the intervention of nicotine. Hematoxylin-eosin staining showed that the activity and quantity of osteoblasts around the implants down-regulated significantly, but acid etching-treated implants showed better outcomes than sandblasting-treated implants.

Objective To explore the association between the polymorphism in IL-28B gene and the interferon virological response in HBeAg-posi-tive chronic hepatitis B patients. Methods A literature search was performed on PubMed,web of Science,China Bio Medicine(CBM)and wan-Fang database. The references was screened with the inclusion and exclusion criteria,and then data were extracted and methodological quality of the studies was judged. Statistical analysis was carried out with RevMan 5.3 and STATA 11.0. Results Totally 7 publications were recruited for the study,including 1 345 patients. The meta-analysis showed that there was no significant difference of interferon response between HBeAg-positive chronic hepatitis B patients with rs8099917TG/GG alleles and rs8099917TT alleles (P= 0.20). There was no statistical difference between Rs12979860CC and CT/TT allele for the sustained virological response(P=0.75). Conclusion Our current meta-analysis suggests that there was no correlation of rs8099917,rs12979860 polymorphism in IL-28B with the sustained virological response to interferon in HBeAg-positive chronic hepatitis b.

Objective To observe the characteristics of hemorheologic changes of hyperlipidemia rats at an early stage and to explore the mechanism of myocardial ischemic injury.Methods Seventy-two SD rats which were fed with high cholesterol diet(cholesterol+lard+pig bile salt) to result in hyperlipidemia model fell into HC group.Thirty-six SD rats which were fed with common diet fell into control group.The rats were fed for 10 to 90 d.At an interval of 10 d,9 time points were set.Therefore the 2 groups were randomly divided into 9 subgroups.At each time point,the changes of plasma lipids,cTnI,hemorheologic parameters,and pathological change of the rats’ myocardium and coronary vessel were assayed.Results The main characteristic of our models was hypercholesterolemia and high low-density-lipoproteins(LDL).With the extension of feeding time,plasma viscosity of HC group increased significantly,and erythrocyte deformability decreased.After fed with cholesterol for 50 d,myocardial ischemic injury occurred in the HC group.Correlation analysis revealed that the incidence of myocardial ischemic injury in hyperlipidemia rats was closely related with hypercholesterolemia and high low-density-lipoproteins.Conclusion The abnormal change of hemorheologic characteristics of hypercholesterolemia is a cause of myocardial ischemic injury.
