Firstly an engine helical intake port 3D model is built by CATIA V5R14. Then the flow numerical simulation of the port is done with Ricardo's CFD software VECTIS. In addition, the port is tested on the steady flow test rig. The calculation result agrees with the test result well.

The surprising excess death rate in patients randomized to tenecteplase plus angioplasty led to premature termination of the trial; less than half of the planned 4,000 patients were enrolled, said Frans Van de Werf, MD, chairman of the cardiology department of the University Hospital Gasthuisberg in Leuven, Belgium. Dr. Van de Werf told Medscape that an increased rate of major bleeding and strokes in the thrombolytics group cannot fully explain the difference in mortality."We're not sure what is going on," he said."Had we selected more experienced cardiologists or more experienced centers for one group?"

在随机分配下，接受tenecteplase加上血管修复术治疗的患者，因为产生令人震惊的超高致死率，这项试验於是提前终止；在比利时鲁汶盖斯堡教学医院心脏病学部的院长Frans Van de Werf医学博士向Medscape表示，原先预期的试验参与者有4千名，只有不到不到一半愿意接受这项试验；溶解血栓剂组有著偏高的大量出血与中风现象，但这并无法解释这一组患者的高死亡率；Van de Werf表示，我们无法确定到底发生了什麼事，难道另外一组的医师与临床中心较有经验？
