让我们先看下面两个片断: 片断一一位病人因为脑血管血栓堵塞以及心脏动脉血管脂肪沉积,导致高位瘫痪。他被抬进高科技医疗室,一位医生给他的动脉血管注入了一种带微小颗粒的注射液(这种小颗粒比粉笔灰尘还小)。通过医疗室的放大透视显示屏幕,只见血管里无数的小颗粒在医师遥控仪的指挥下,四处出击,不一会,就把病人脑部的血栓块“挖”掉了。接着,小颗粒又游到 Let’s look at the following two pieces first: Piece One patient was paralyzed at a high level because of blockage of cerebrovascular thrombus and deposition of fat in the heart artery. He was carried into a high-tech medical room, and a doctor injected his arterial blood with an injection of tiny particles smaller than chalk dust. Through the magnification fluoroscopy display screen in the medical room, I saw innumerable small particles in the blood vessels under the command of a physician’s remote controller. After a long attack, the thrombus in the brain of the patient was “dug up” after a short while. Then, the small particles swim again
