ABSTRACT
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.
ABSTRACT
Objective To investigate the relationship between serum resistin,leptin and adiponectin with microangiopathy in the patients with type-2 diabetes mellitus(T2DM).Methods One hundred and twenty patients with T2DM in our hospital were selected and divided into the non-microangiopathy group (NON-MAP,60 cases) and microangiopathy group (MAP,60 cases) according to whether complicating microangiopathy.Other 60 individuals undergoing healthy physical examination were selected as the normal control group(NC).Fasting serum resistin,adiponectin and leptin levels were detected in each group.Fasting blood glucose,insulin and blood lipid levels were also detected.The insulin resistance was evaluated by using insulin resistance index(HOMA-IR).Results The levels of serum resistin,leptin,free fat acid(FFA) and hs-CRP in the NON-MVP group and MVP group were signifi cantly higher than those in the NC group,while the adiponectin level was sigrnificantly lower than that in the NC group,the difference was statistically significant(P＜0.05).The correlation analysis showed that serum resistin and leptin levels had positive correlation with hs-CRP,FFA,HOMA-IR and TG(P＜0.05),and had negative correlation with HDL-C(P＜0.05);the adiponectin level was negatively correlated with hs-CRP,FFA,HOMA-IR and TG,while positively correlated with HDL-C(P＜0.05);serum resistin and leptin levels had positive correlation,both had significantly negative correlation with adiponectin;with serum resistin,leptin and adiponectin as the dependent variables,the multiple stepwise linear regression analysis showed that HOMA-IR and waist to hip ratio had maximal influence on them.Conclusion Serum resistin and leptin levels increase and adiponectin level decrease in T2DM patients suggests that serum resistin,leptin and adiponectin are correlated with T2DM occurrence as well as microangiopathy occurrence.
ABSTRACT
Objective To examine the association between serum resistin levels and the severity of coronary artery lesions and cardiovascular risk factors in postmenopausal women.Methods The study population consisted of 117 postmenopausal women who underwent diagnostic coronary angiography for evaluation for suspected myocardial ischemia.Fasting serum resistin,insulin,blood glucose(BG),high-sensitive C-reactive protein(hs-CRP),fibrinogen(Fib)and lipid profile,including total cholesterol(TC),triglycerides(TG),HDL-cholesterol(HDL-C),LDL-cholesterol(LDL-C),apolipoprotein A1(Apo A1),apolipoprotein B(Apo B)and lipoprotein(a)(Lp(a))were measured in all the patients.Patients were divided into four groups according to the score of their coronary artery lesions:group Ⅰ included patients with coronary artery lesion score 0(no evidence of CAD),while group Ⅱ with score 1(mild lesion),group Ⅲ with score 2(moderate lesion),and group Ⅳ with score 3(severe lesion).Only patients with moderate to severe coronary lesions were diagnosed as coronary artery disease(CAD).Results Among the 117 patients,74 were diagnosed as CAD patients.Patients with CAD had significantly higher levels of resistin compared with controls:[4(1-10)?g/L vs 2(0-4)?g/L,median(interquartile range),P=0.002].In multiple logistic regression analysis,resistin levels were associated with CAD independent of age,BMI,metabolic syndrome,history of hypertension(HTN),diabetes(DM),dyslipidemia,smoking,SBP,DBP,hs-CRP,lipids [TC,TG,HDL-C,Apo A1,Apo B,Lp(a)],Fib,BG and insulin(OR 1.131,95%CI 1.012-1.263,P=0.030).Resistin levels correlated positively with CAD lesion severity in postmenopausal women(r=0.231,P
