International Circulation:  Okay how about for you personally， which ones interested you the most?  Which one did you like the best?
　　Dr Morgenstern:  So I pretty much enjoyed a session on how aggressive we should be in caring for patients with intracerebral hemorrhage.  There was a lively debate about whether we are able to make good prognostic judgement in patients with intracerebral hemorrhage and whether it was appropriate to do so and what and how much we should value and include the feelings of family and preferences， values， and religious perspectives of family members.  I thought that was really excellent.  There was an important session for nurses about evidenced based nursing and working within a hospital system to apply evidence based nursing.  I thought that was very good so that was a couple of things I enjoyed.
　　International Circulation:  Can you define evidence based nursing?
　　Dr Morgenstern: Using scientific literature and guideline statements to determine how to care for patients.
　　International Circulation:  Recently you published an article that suggested CT scanning for intracerebral hemorrhaging may not be necessary in all patients with symptoms of dizziness.  What is your opinion about CT scans being used as a valuable tool in the emergency room for patients who are presenting with dizziness?
　　Dr Morgenstern: Our paper was looking at the behavior of physicians when patients present with dizziness which is a very unusual， very isolated symptom for stroke.  So CT scans are absolutely necessary and mandatory in all paitnets who present with stroke symptoms in the emergency department.
　　Internatioanl Circulation:  Stroke is the leading cause of death in China so Chinese doctors do need to possess the most complete understanding of the disease and cure.  Please introduce our readers to the latest cutting edge diagnosis and rehabilitation devices and the techniques for treating stroke patients.
　　Dr Morgenstern: Well there are a lot of new technologies out there but they need to be tested and I think that one of the things that we discussed at a lot of the meeting is whether the use of these technologies really improved patient care.  And I think we do not know the answer to that yet.  So there were several presentations about using MRI machines to look at diffusion and perfusion mismatch in ischemic stroke.  There remains a lot of debate about the value of that and there is a need for a lot further study to determine that.  The same is true of CT applications and CT perfusion so I take that that is important.
