Objective:To analyze the correlation among human retinol binding protein 4(RBP4),miR-1-3p,re-combinant human vitamin D binding protein(VDBP)and severity of ST-segment elevation myocardial infarction(STEMI)based on SYNTAX score and their diagnostic value for it.Methods:A total of 162 STEMI patients admit-ted to our hospital for treatment from January 2020 to June 2021 were selected as STEMI group,and another 67 healthy subjects who received physical examination in our hospital simultaneously were selected as healthy control group.According to SYNTAX score,STEMI group was further divided into low risk group(n=68,＜22 points),medium risk group(n=53,23 points≤SYNTAX score≤32 points)and high risk group(n=41,＞33 points).Lev-els of RBP4,VDBP and miR-1-3p expression were compared among above groups.Diagnostic value of single and combined detection of above indexes for severity of STEMI were analyzed.Correlation between SYNTAX score and above indexes were analyzed in STEMI patients.Results:Compared with healthy control group,there were signifi-cant rise in levels of RBP4[(47.18±5.24)μg/L vs.(81.40±6.11)μg/L]and VDBP[(2.36±0.75)μg/ml vs.(3.55±1.04)μg/ml],and significant reduction in miR-1-3p expression[(1.18±0.13)vs.(0.72±0.07)]in STEMI group,P＜0.001 all.Compared with low risk group,there were significant rise in levels of RBP4[(69.97±2.98)μg/L vs.(85.23±3.76)μg/L vs.(95.41±3.16)μg/L]and VDBP[(3.19±0.50)μg/ml vs.(3.55±0.52)μg/ml vs.(4.16±0.64)μg/ml],and significant reduction in miR-1-3p expression[(0.80±0.05)vs.(0.70±0.04)vs.(0.61±0.03)]in medium risk group and high risk group,and levels of RBP4 and VDBP in high risk group were significantly higher than those of medium risk group,miR-1-3p expression in high risk group was significantly lower than that of medium risk group(P＜0.001 all).ROC analysis indicated that area under the curve(AUC)of combined detection of above indexes was 0.892,which was significantly higher than each single detection(Z=4.787,3.078,2.495,P＜0.05 or＜0.01).Spearman correlation analysis indicated that STEMI severity was significant positively correlated with levels of RBP4 and VDBP(r=0.849,0.776,P＜0.001 both),and significant inversely correla-ted with miR-1-3p expression(r=-0.790,P＜0.001).Conclusion:Levels of RBP4 and VDBP,and miR-1-3p ex-pression can reflect severity of STEMI patients.Triple combined detection possesses high diagnostic efficacy for disease se-verity,which can be used as clinical important indexes for assessing patient's condition.
