ABSTRACT
Objective To explore the prognostic value of biomarkers in type 2 diabetic patients with acute myocardial infarction (AMI), this study was to investigate the associations between the neutrophil to lymphocyte ratio (NLR), the Global Registry of Acute Coronary Events (GRACE) score and in-hospital mortality. MethodsSeven hundred and seven consecutive AMI patients were divided into diabetic group (DM-AMI group), impaired glucose tolerance group (IGT-AMI group), and normal glycemic group (NGT-AMI group). The laboratory and clinical characteristics were assessed retrospectively from the medical records. The NLR and GRACE score were calculated. Results In AMI patients, the DM-AMI group had significantly higher NLR and GRACE scores compared with those from the IGT-AMI group and NGT-AMI group (P>=Neutrophil to lymphocyte ratio; In-hospital mortality; Acute myocardial infarction; Diabetes mellitus, type 2
ABSTRACT
The effect of atorvastatin on warfarin-induced aortic medial calcification and systolic blood pressure (SBP) of rats induced by warfarin was studied. Thirty healthy and adult rats were randomly divided into Warfarin group (n=10), Atorvastatin group (n=10) and normal control group (n=10). Caudal arterial pressure of rats was measured once a week, and 4 weeks later, aorta was obtained. Elastic fiber, collagen fiber and calcium accumulation in tunica media of cells were measured by Von Kossa staining. The results showed that warfarin treatment led to elevation of systolic blood pressure and aortic medial calcification. The chronic treatment also increased collagen, but decreased elastin in the aorta. However, the atorvastatin treatment had adverse effects. It was concluded that treatment with atorvastatin presented evidence of blood pressure lowing and calcification reducing. These data demonstrate that atorvastatin protected aortic media from warfarin-induced calcification and elevation of systolic blood pressure.

AIM:To study the effect of acyl coenzyme A:cholesteryl acyltransferase 1(ACAT1)antisense oligonucleotides on the formation of foam cells(FC).METHODS:THP-1 cells were cultured and differentiated into macrophages(MP)by phorbol myristate acetate(PMA).Over-expressing ACAT1 gene THP-1 cells were constructed.The ACAT1 antisense and missense oligonucleotides conducted by LipofectamineTM 2000 were incubated with above cells.Ac-LDL was added 6 h later and incubated for 24 h.The expression of ACAT1 protein was detected by Western blotting.The ACAT activity was measured by quantifying the incorporation of 1-14C oleoyl CoA into cholesteryl esters.The formation of foam cells was detected by oil red O staining.RESULTS:The ACAT1 antisense oligonucleotides inhibited the activity of ACAT in macrophages and over-expressing ACAT1 gene THP-1 cells.It also inhibited the formation of foam cell in macrophages and over-expressing ACAT1 gene THP-1 cells with lipid loading.The missense oligonucleotides did not show the inhibitory effects.CONCLUSION:The ACAT1 antisense oligonucleotides inhibit the activity of ACAT and the formation of foam cells.
