Clinical value of LP-PLA2 and serum resistin in predicting the prognosis of atherosclerotic cerebral infarction / 医学研究生学报

Objective Few studies are reported about the values of the levels of plasma lipoprotein related phospholipase A2 (LP-PLA2) and serum resistin in predicting the prognosis of atherosclerotic cerebral infarction (ACI).This article aims to evaluate the predictive values of LP-PLA2 and serum resistin in the prognosis of ACI.Methods This study included 136 cases of ACI diagnosed and treated in Huaihe Hosptial from September 2013 to September 2014.The patients were followed up for 2 years,during which 48 were found with adverse outcomes (the poor prognosis group) 76 without disease progression (the good prognosis group).We analyzed the influencing factors on prognosis using the Cox proportional hazard model and evaluated the sensitivity and specificity of these factors in predicting the prognostic risks of the patients by ROC curve analysis.Results The rate of poor prognosis was 38.71％ among the included patients.Analysis with the Cox proportional hazard model showed significant impacts of LP-PLA2 (OR =2.105,95％ CI:1.878-2.413) and serum resistin (OR=1.784,95％ CI:1.509-2.213) on the prognosis of the patients.Compared with the good prognosis group,the poor prognosis group exhibited markedly higher levels of LP-PLA2 ([128.78±76.22] vs [268.65±89.02] mg/L,P＜0.01)and serum resistin ([20.71±6.15] vs [24.36±4.87] mg/L,P＜0.01).The sensitivity and specificity of LP-PLA2 combined with serum resistin were 81.35％ and 78.26％,respectively.Conclusion The combination of LP-PLA2 with serum resistin has a good predictive value for the prognosis of atherosclerotic cerebral infarction and is expected to be widely applied as a routine index in clinical practice.

Effects of different statin regimens on lipid profile and serum metalloproteinases in patients with coronary heart disease / 中华心血管病杂志

<p><b>OBJECTIVE</b>Patients with coronary artery disease (CAD, stenosis between 50% - 70% evidenced by coronary angiography) were treated with atorvastatin 40 mg (n = 19) or atorvastatin 10 mg in combination with ezetimibe 10 mg (n = 23). Blood lipid profile and metalloproteinases were monitored up to 3 months.</p><p><b>METHODS</b>Cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), liver function, renal function, creatine kinase, MMP-2, MMP-9, TIMP-1 were measured at baseline and at 1 month and 3 months post therapy.</p><p><b>RESULTS</b>(1) At 3 months, LDL-C was similarly reduced in monotherapy group [(1.94 +/- 0.49) mmol/L, 37.82% reduction compared to baseline] and in combined therapy group [(1.92 +/- 0.54) mmol/L, 38.26% reduction compared to baseline]. (2) AST, ALT, renal function and creatine kinase remained unchanged post various therapy (all P > 0.05). (3) MMP-2, MMP-9 significantly decreased and TIMP-1 significantly increased at 3 months compared to baseline in monotherapy group but these parameters remained unchanged in combined therapy group.</p><p><b>CONCLUSION</b>Both therapy regimens were well tolerated and similarly effectively reduced blood lipids and 40 mg atorvastatin monotherapy regimen is superior to atorvastatin 10 mg plus ezetimibe 10 mg regimen in improving metalloproteinases parameters.</p>

Homocysteine-induced apoptosis of endothelial cells and roles of caspase3 / 上海第二医科大学学报

Objective To investigate whether homocysteine(Hcy) induces apoptosis of endothelial cells via a pathway involving caspases3 and whether simvastatin antagonizes the proapoptotic effects of Hcy by regulating c-IAP. Methods Human umbilical vein endothelial cells(HUVEC) were treated with Hcy,with or without simvastatin,for 24 h.Cell apoptosis was evaluated by Annexin V staining and flow cytometery,as well as TUNEL.The mRNA and protein levels of caspase3,c-IAP-1 and c-IAP-2 were analyzed by RT-PCR and Western blot,respectively. Results Treatment with both low(0.5 mmol/L) and high(3.0 mmol/L) concentrations of Hcy-induced HUVEC apoptosis was accompanied by an increased level of caspase3 expression and activation,together with decreased c-IAP-1 and c-IAP-2 level.Simvastatin upregulated c-IAP-1 and c-IAP-2 expression while attenuated Hcy-induced apoptosis and caspase3 activation. Conclusion Hcy may induce HUVEC apoptosis via a pathway involving caspase3,which can be partially antagonized by simvastatin,possibly through upregulated c-IAP-1 and c-IAP-2 expression.

Effects of atorvastatin on liver cystathionine-?-synthase of apoE~(-/-) mice / 上海第二医科大学学报

Objective To explore the influence of homocysteine(Hcy)on liver cystathionine-?-synthase(CBS)and methylenetetrahydrofolate reductase(MTHFR)system in apoE-/- mice,and determine the effects of atorvastatin and/or folate/vitamin B12 on liver CBS and MTHFR system.Methods Eighty male 6-week-old apoE-/- mice were randomly divided into two groups:65 mice were fed with a chow diet containing 2%(wt/vol)L-methionine(homomethionine group)and 15 mice were fed with normal saline(control group).Two months later,the 60 mice survived in homomethionine group were subdivided into four groups:group Ⅰ(untreated),Ⅱ(3 mg/kg atorvastatin),Ⅲ(3 mg/kg atorvastatin+2 mg/kg folate+30 ?g/kg vitamin B12)and Ⅳ(2 mg/kg folate+30 ?g/kg vitamin B12).After one month,Western blotting was performed to detect the liver CBS and MTHFR system protein expression in each group.Results The relative expression of liver CBS and MTHFR was significantly lower in group Ⅰ than in control group(P

Clinical Significance of Plasma Homocysteine Level in Congestive Heart Failure / 上海第二医科大学学报

Objective To examine the relationship between plasma homocysteine level and status of congestive heart failure. Methods Plasma homocysteine level was determined in 106 patients with congestive heart failure(CHF).Among them,40 patients were diagnosed as having recent onset of CHF(group 1) and the remaining 66 were receiving conventional treatment(group 2).Thirty healthy subjects were served as a control group. Results(The plasma) homocysteine levels in group 1,group 2 and the control group were(14.87?5.22),(13.25?5.45) and((7.52)?1.73) ?mol/L,respectively.The plasma homocysteine level was significantly higher in group 1 and group 2 than in the control group(P

Role of Nuclear Factor kappa B in Neointima Formation after Balloon-Injured Rat Artery / 上海第二医科大学学报

Objective We examined the in vivo effect of the antisense or/and decoy oligonucleotide of nuclear factor-?appa B (NF-?B) on balloon-injured smooth muscle cell proliferation and MMP-9 in the carotid artery of rats. Methods Sprague-Dawley rats underwent balloon-dilation injury of the left carotid artery. Rats were divided into 7 groups(n=18) and each group included 6 time points (6 h and 1,3,5,7,14 d)(n=3). Results The mean intima/media ratio increased significantly in sense group、scramble group and model group and reached the maximum at 7 d after rat injured carotid artery, compared with normal group, antisense group, decoy group and decoy plus antisense group(P
