Abstract:
Objective:Bone morphogenetic protein-4(BMP4)has been proved to be an important regulatory factor for the pathological process of atherosclerosis(AS).However,there are few related clinical studies.This study aims to investigate the levels of plasma BMP4 in patients suffering from the arterial occlusive diseases(ACD)characterized by AS,and further to test the relationship between BMP4 and inflammation and vascular injury. Methods:A total of 38 ACD patients(the ACD group)and 38 healthy people for the physical examination(the control group)were enrolled.The plasma in each subject from both groups was obtained to test the levels of BMP4,tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-10,and vascular endothelial cadherin(VE-cadherin),and the relationship between BMP4 and the detected indicators above were further analyzed. Results:Compared with the control group,the patients in the ACD group displayed significant elevations in the neutrophil to lymphocyte ratio[NLR,1.63(1.26,1.91)vs 3.43(2.16,6.61)]and platelet to lymphocyte ratio[PLR,6.37(5.26,7.74)vs 15.79(7.97,20.53)],while decrease in the lymphocyte to monocyte ratio[LMR,5.67(4.41,7.14)vs 3.43(2.07,3.74)](all P<0.05).Besides,the ACD patients displayed significant elevations in plasma BMP4[581.26(389.85,735.64)pg/mL vs 653.97(510.95,890.43)pg/mL],TNF-α[254.16(182.96,340.70)pg/mL vs 293.29(238.90,383.44)pg/mL],and VE-cadherin[1.54(1.08,2.13)ng/mL vs 1.85(1.30,2.54)ng/mL],and decrease in IL-10[175.89(118.39,219.25)pg/mL vs 135.92(95.80,178.04)pg/mL](all P<0.05).While the levels of IL-1β remained statistically comparable between the 2 groups(P=0.09).Furthermore,the plasma BMP4 levels were further revealed to be positively correlated with the levels of IL-1β(r=0.35),TNF-α(r=0.31)and VE-cadherin(r=0.47),while they were negatively correlated with the levels of IL-10(r=-0.37;all P<0.01). Conclusion:After ACD occurrence,the patients'plasma concentrations of BMP4 would be upregulated,which may serve as a candidate to indicate the levels of inflammation and vascular injury.
