...实验中发现,治疗量的raloxifene具有一定的保护心脏的作用,而在高于治疗浓度时能阻断hERG钾通道以及缓慢激活延迟整流钾通道(IKs),但在心脏离体灌流装置中并未发现QRS和QT间期的延长。目前,对于发生这种现象的具体机制尚需进一步研究探讨。

Methods: According to the recent datum on potassium channels physiological character and disease were reviewed focuses.
And actually, a question that might come up, I just explained, the sodium channel, you might say, well, how do potassium channels work then, because I can understand how you can filter something big out, but how do you filter out something small.
实际上,可能大家会问一个问题,我刚解释过,钠离子通道,你可以说,好吧,那么钾离子通道该如何起作用呢,因为我可以理解你是如何把大东西过滤掉的,但是你如何把小东西过滤掉呢?
The ones that are most important in physiology are ones that only allow ions to go through: sodium, potassium, chloride, calcium, bicarbonate.
在生理学上这种,只能允许某种离子通过的通道十分重要,这些离子包括钠离子,钾离子,氯离子,钙离子和碳酸氢根离子
And that's all that's big enough to pass through or small enough to pass through. And if we go up even just one row on the periodic table to potassium, what we actually see is now that it's going to be too large, and, in fact, a potassium solvated with one water molecule won't go through our channel.
就是这样刚好大到它通过,或者说刚好小到它通过,即使我们再沿着周期表往下走仅仅一行到钾离子,我们看到的就将是它的个头太大了,实际上,溶解于一个水分子的单个钾离子,不能穿过我们的通道。
