1、1房顫病人心房肌漿網 RyR2 受體 mRNA 表達變化的研究作者：周炯峰 夏小杰 陳怡粵【摘要】 目的：研究心房顫動（房顫）患者肌漿網鈣釋放通道ryanodine 受體（ryanodine receptor type2, RyR2）mRNA 表達的改變，探討房顫電重構與結構重構的發生機制。方法：38 例風心病二尖瓣狹窄接受外科手術者，手術時取右心房及右心耳各約 100 mg，通過逆轉錄 - 聚合酶鏈反應技術， 以 GAPDH 為內參照， 測量肌漿網 RyR2受體的 mRNA 的變化。結果：房顫者肌漿網 RyR2 受體 mRNA 較竇性心律者上調，心房不同部位無差別。結論：房顫患者 RyR2 2、受體 mRNA上調，說明肌漿網 Ca2+ 超負荷與肌漿網鈣庫的釋放增加有關。【關鍵詞】 心房顫動；鈣調蛋白；肌漿網Abstract Objective To investigate the change of RyR2receptor mRNA expression in sarcoplamicreticular and to explorethereasonsforcalciumoverloadingininitiatingandmaintaining atrial fibrillation (AF).Methods 38 patients withmitral stenosis under3、going open heart surgery were studied. 100mg tissuewas obtained from the right appendage and the rightatrium respectively. The messenger ribonucleic acid(mRNA)2amount of intracellular stored calcium releasing genes ofsarcoplamicreticularwasmeasuredbyreversetranscription-polymerasechainreaction(RT-PCR)andnormalized to the mRNA levels of glyceraldehydes 3-phosphatedehydrogenase (GAPDH).
