Relationship between TRPV1 gene polymorphism and genetic susceptibility to type 2 diabetes mellitus and intraoperative adverse cardiovascular events / 中华麻醉学杂志

ABSTRACT

Objective:To determine the relationship between transient receptor potential vanilloid 1 (TRPV1) gene polymorphism and genetic susceptibility to type 2 diabetes mellitus (DM) and intraoperative adverse cardiovascular events (ACVEs).Methods:Eighty-six DM patients and 78 non-DM patients (nDM) undergoing elective knee replacement or posterior lumbar interbody fusion were selected in this study.Real-time fluorescence quantitative polymerase chain reaction was carried out to genotype the rs222747 variant of TRPV1 gene.The ACVEs occurred were recorded during operation, and the risk factors for ACVE developed during operation were identified.Results:Compared with nDM group, the TRPV1 genotype G/G ratio, allele G frequency, and incidence of intraoperative ACVE were significantly increased in DM group ( P<0.05). Aging and TRPV1 genotype GG combined with DM were the risk factors for intraoperative ACVEs occurred ( P<0.05). Conclusion:TRPV1 gene polymorphism is related to the genetic susceptibility to type 2 DM and occurrence of intraoperative ACVEs.
