摘要 目的:观察心房纤颤(AF)对心房κ-阿片肽受体mRNA表达的影响。方法:于心脏外科手术时收集21例窦性心律(SR)及21例持续性AF患者的心房组织,采用RT-PCR方法,研究其心房κ-阿片肽受体mRNA表达量的变化。结果:与SR组相比,AF组κ-阿片肽受体mRNA表达量减弱[(262±20)∶(196±11),P<0.05]。结论:在持续性AF时,κ-阿片肽受体mRNA表达下调,表明AF的心房组织自我保护能力减弱。 Objective: To study the effects of atrial fibrillation on the expression of κ-opioid receptor. Methods: RT--PCR was used to detect and compare the mRNA expression of κ-opioid receptor in human atria tissue of patients with atrial fibrillation (AF) or sinus rhythm (SR). Results: Compared with the group of SR, the κ-opioid receptor mRNA amounts in AF significantly decreased [ (262±20) vs. (196± 11), P〈0. 05]. Conclusion: The decrease of κ-opiold receptor mRNA suggests certain protective capacity decrease in the persistent fibrillating atrial tissue.
