Objective To study the clinical value of heart‐type fatty acid binding protein(H‐FABP) ,high‐sensitive cTnI(hs‐cT‐nI),homocysteine(Hcy)andcystatinc(Cys‐C)intheearlydiagnosisofacutemyocardialinfarction(AMI).Methods 150casesof AMI patients with coronary arteriography (AMI group) were selected from the cardiovascular department admitted within the first 6hours of chest pain attack .An additional 30 case for control group .The level of four novel cardiac marker were measured in each group of serum .Results The level of serum H‐FABP ,hs‐cTnI ,Hcy and Cys‐C in AMI group were markedly higher than control group(P<0 .05) ,and rose with the increase of coronary artery lesions with statistical difference (P<0 .05) .Each cardiac markers showed high specificity in the diagnosis of AMI ,amongst which H‐FABP and hs‐cTnI ,stood out with sensitivity of 97 .34% and 89 .98% respectively .With Youden index ,positive likelihood ration ,negative likelihood ration ,positive predictive value and negative predictive value ,H‐FABP and hs‐cTnI appeared to have higher diagnostic value than Hcy and Cys‐C in AMI .Conclusion H‐FABP and hs‐cTnI displayed significant clinical value as a most sensitive indicator in the early diagnosis of AMI (within 6 hours of attack) . The level of H‐FABP ,hs‐cTnI ,Hcy and Cys‐C elevated as coronary artery lesions increase .

To evaluate the value of serum human epididymis protein 4(HE4),cancer embryonic antigen(CEA), carbohydrate antigen(CA125,CA19-9,CA153),alpha fetoprotein(AFP) and β-human chorionic gonadotrophin (β-HCG) in ovarian cancer early diagnosis.Methods:Abbott Architect i2000SR was used to detect the levels of preoperative serum tumor markers (n=7) in ovarian cancer group,benign ovarian tumor group and the normal control (each n=60).Results:The levels of serum HE4,CA125, CA199,CEA,CA153,AFP and β-HCG in ovarian cancer group were markedly higher than the benign ovarian tumor group and the control group.There was statistically significant difference ( P<0.05 ).The diagnosis of ovarian cancer tumor markers were high specificity,but sensitivity was not high except HE4 (76.67%) and CA125 (68.33%).With Youden Index,the area under curve of ROC,the HE4 was demonstrated higher specificity ,sensitivity and accuracy.There was also medium diagnostic value of CA 125 ,CA199 and CEA for ovarian cancer.The sensitivity of ovarian cancer diagnosis is raised by combined assay with serum tumor marker ,but the specificity would be reduced accordingly.HE4, CA125, CA199 and CEA combined detection is considered the best.Conclusion:CA153,AFP and β-HCG have lowered diagnosis for ovarian cancer.HE4, CA125, CA199 and CEA combined detection could significantly improve specificity ,sensitivity and accuracy in the early diagnosis of ovarian cancer.
