RESUMEN
Objective:To investigate association between the single nucleotide polymorphisms of endothelial protein C receptor (EPCR) gene and the risk of Kawasaki disease (KD) in a Chinese children.Methods:A total of 103 KD patients including 23 patients with coronary artery lesions (CAL) and 158 controls were recruited.Seven tagging SNPs (rs6088738,rs2069940,rs2069945,rs2069952,rs867186,rs9574,and rs1415774) of EPCR gene were selected for TaqMan allelic discrimination assay.The plasma soluble EPCR (sEPCR) levels of 53 KD and 52 healthy children were detected by ELISA.Results:We found a significant association between rs2069952,rs9574 or rs1415774 and higher probability for the occurrence of KD but not CAL formation.Interestingly,males with these 3 SNPs and rs2069945 SNPs bore a much greater risk of KD than females.The level of plasma sEPCR in children with KD didnot predict the formation of CAL.However,the allele G of rs867186 in EPCR was associated with the increased level of plasma sEPCR in KD patients.Conclusion:The SNPs of EPCR are associated with KD susceptibility in a Chinese Han children.
RESUMEN
Objective To investigate the clinical value of human soluble endothelial protein C receptor (sEPCR) after heart valve replacement.Methods 78 cases of patients with heart valve replacement in the Second Affiliated Hospital of Nantong University from January 2005 to June 2016 were selected as the research objects,who were divided into embolic group and control group,38 cases in embolic group and 40 cases in control group,the index of two groups 1 d preoperative,while dynamic monitoring international standardization ratio (INR) and embolism,were detected,of which INR and sEPCR were examined.The INR and sEPCR oftwo groups was compared with t test.Results The INR and sEPCR of two groups 1 d preoperative had no significant difference (1.24±0.32 vs 1.23±0.19,34.91±9.14 μg/L vs 35.56±10.22 μg/L;t=0.17,P =0.868;t=0.30,P=0.768,respectively).The average value of dynamic monitoring INR in control group had no significant difference when compared with the results of embolism (1.86±0.95 vs 1.93±0.97,t=0.32,P=0.748).But the sEPCR had significant difference (101.33±27.15 μg/L vs 41.67±11.82 μg/L,t=12.69,P=0.000).Conclusion The important indexes of sEPCR could effectively guide the anticoagulant treatment,especially those who with the sEPCR value too high,the embolic threatening should be paid attention to.
RESUMEN
El choque séptico es una de las principales causas de muerte en la unidad de cuidados críticos y es un problema de salud pública. La respuesta inflamatoria sistémica descontrolada desempeña un papel crítico en la patogenia de la sepsis y del choque séptico. El desequilibrio de los mecanismos que controlan la coagulación e inflamación favorecen el desarrollo de coagulación intravascular diseminada. La interacción entre la inflamación y la coagulación es la pieza clave de la patogénesis de la sepsis y el choque séptico. La trombomodulina, proteína C, trombina y el receptor endotelial de la proteína C (TM-PC-T-REPC) forman un complejo en la superficie del endotelio que mantiene el microambiente endotelial en un estado antiinflamatorio y anticoagulante. El objetivo de este trabajo es revisar el papel crítico que tiene el complejo TM-PC-T-REPC en la interacción entre inflamación y coagulación en sepsis y el uso de la trombomodulina recombinante como una nueva alternativa terapéutica para el manejo de la sepsis grave y el choque séptico.
Septic shock is a leading cause of death in intensive care units and a public health problem. Uncontrolled systemic inflammatory response plays a critical role in the pathogenesis of sepsis and septic shock. Alterations in the mechanisms controlling coagulation and inflammation may lead to disseminated intravascular coagulation. The interaction between inflammation and coagulation is central to the pathogenesis of both septic shock and sepsis. Thrombomodulin, protein C, thrombin, and endothelial protein C receptor (T-PC-T-EPCR) bind simultaneously forming a complex on the surface of the endothelium. This complex maintains the endothelial microenviroment in an anti-inflammatory and anticoagulant state. The objective of this paper is to review the critical role that TM-PC-T-EPCR complex plays in the interaction between inflammation and coagulation in sepsis and the use of recombinant thrombomodulin as a new therapeutic alternative in the management of serious sepsis and septic shock.
RESUMEN
Objective:To investigate the clinical significance of soluble thrombomdulin (sTM)、endothelial protein C receptor (sEPCR) and von Willebrand factor (vWF) in patients with renal transplantation and reject reaction.Methods:The plasma levels of sTM, sEPCR and vWF were successively determined by double antibody sandwich enzyme linked immunoadsordent assay (ELISA) in 42 patients with renal transplantation and reject reaction, and were compared with normal groups.Results:The levels of sTM, sEPCR and vWF in postoperative of renal transplantation patients were higher than those in preoperative ( P 0 05). In patients with renal transplantation, the levels of sTM, sEPCR and vWF each have positive correlation(r=0 595 P
