Objective:To explore the role of lectin-like oxidized low density lipoprotein (ox-LDL) receptor(LOX1) in ox-LDL stimulating endothelial nitric oxide(NO) production. Methods: LOX1 mRNA expression was detected by reverse transcription-polymerase chain reaction(RT-PCR). The quantity of NO was detected by Enzyme-method. Results: Incubation of ox-LDL increased endothelial NO production and LOX1 mRNA expression. When HUVECs were incubated with ox-LDL as well as the inhibitor of LOX1, polyinosinic acid,the increase of NO production and LOX1mRNA expression were attenuated. Conclusion: Ox-LDL enhanced endothelial NO production in a concentration-dependent manner, and the effect of ox-LDL on endothelial NO was mediated by LOX1.

Objective To evaluate the effects of the short-term intervention lifestyle intervention on metabolic measurements of community patients with impaired glucose regulation (IGR). Methods A total of 90 IGR participants were randomly assigned to the control group (n=45) or the intervention group (n= 45). The subjects in the control group received routine diet and physical exercise advice once a month. The subjects in the intervention group received additional individualized diet counseling and circuit-type resistance training. Metabolic parameters were compared before or after the intervention between the two groups. Results In oral glucose tolerance test (OGTT),2-h plasma glucose (PG) and homeostasis model of insulin resistance index (HOMA-IR) were significantly decreased in the intervention group at 3 months(F= 13.47 or 82.25 ,both P < 0.05). Body mass index (t=-2.44, P<0.05), systolic blood pressure (t= -3.39, P<0.05), diastolic blood pressure (t=-3.97, P<0.05), fasting plasma glucose (t=-3.89, P<0.05),2-h PG (t=-7.22,P <0.05) ,total cholesterol (t=-2.72,P<0.05),low-density lipoprotein cholesterol (t=-2.74, P<0.05), and glycosylated hemoglobin A1 C (t=-3.73, P<0.05) were significantly declined in the intervention group compared to the control group (all P<0.05). Conclusions Intensive lifestyle intervention can significantly improve the metabolic markers of IGR subjects and should be used to prevent type 2 diabetes.

Objective To investigate the value of mesenteric vascular CTA in the diagnosis of small intestinal neoplasms.Methods A retrospective analysis of mesenteric CTA from January 2008 to April 2013 was conducted in 51 patients with pathologically proven small intestinal neoplasms.Features of intestinal neoplasms CTA signs including neoplasm feeding artery,draining vein,mesangial side vasa recta and the formed neoplasm vessels,were observed.Two radiologists individually used two methods,namely intestinal tumor feeding artery positioning method and Cole fractionation method,for diagnosis and localization diagnosis of tumor,and also for comparing the results with those of surgical pathology.McNemar Chi-square test was adopted to evaluate the diagnosis differences between the two physicians and between the two methods by the same physician.Kappa value was used to assess the consistency of the results.Results Features of intestinal tumors CTA signs:12 cases of enlarged neoplasm feeding artery,9 cases of early displayed draining vein,22 cases of enlarged mesangial side vasa recta,and 11 cases of vessels formed inside and around the neoplasm,single lesion for all and the largest lesion diameter≥ 5 cm for 37 cases.The accuracy of Cole fractionation method positioning and the feeding artery positioning were 84.31％(43/51) and 98.03％(50/51) respectively.Moderate consistency(Kappa=0.49,P＜0.01) was seen with Cole fractionation method by the two physicians and high consistency(Kappa=1.00,P＜0.01) with feeding artery positioning method.McNemar Chi-square test showed no significant difference between the two methods by the same physician and the consistency of the results from the two methods was passable(P were 0.062 and 0.125).Conclusion Mesenteric CTA can display the intestinal tumor feeding arteries and draining veins,and is helpful in identification of the relationship between the tumor and its surrounding blood vessels,which can improve the accuracy of pre-operative localization and qualitative diagnosis for small intestinal tumor.
