Abstract:
Objective :To explore plasma expression levels of human maternal expression gene 3 (MEG3) and urotheli-al carcinoma antigen 1 (UCA1) in patients with acute myocardial infarction (AMI) and their clinical significance . Methods : A total of 90 AMI patients treated in our hospital were enrolled as AMI group ,and 50 healthy subjects un-dergoing physical examination in our hospital simultaneously were treated as healthy control group .Plasma expres-sions of MEG3 and UCA1 ,serum levels of creatine kinase isoenzyme MB (CK-MB) and cardiac troponin I (cTnI) were observed and compared between healthy control group and AMI group on 1h ,3h ,6h and 12h after onset . Spearman correlation analysis was used to analyze their correlation .Results : Compared with healthy control group , there was significant rise in plasma MEG3 expression [ (0-002 ± 0-001) vs .0-017 ± 0-003)] ,and significant reduc-tion in UCA1 expression [ (0-027 ± 0-005) vs .(0-017 ± 0-002)] in AMI group on 1h after onset , P＝0-001 both ;after 3h ,there were significant rise in serum levels of CK-MB [ (20-01 ± 3-05) IU／L vs.( (32-10 ± 4-40) IU／L] and cTnI [ (1-01 ± 0-87) ng／L vs.(2-10 ± 0-91) ng／L] in AMI group , P＝0-001 all.Spearman correlation analy-sis indicated that in plasma MEG3 expression was significant positively correlated with serum CK-MB and cTnI levels ( r＝0-351 ,0-368 , P＜0-05 both) ,and plasma UCA1 expression was significant inversely correlated with serum levels of CK-MB and cTnI (r＝ －0-416 ,－0-425 , P＜0-01 both) AMI patients .Conclusion : Plasma MEG3 level significant rises ,and UCA1 level significantly reduces in AMI patients during early onset period .Both are signifi-cantly correlated with CK-MB and cTnI levels ,which may be used as new markers diagnosing early AMI .
