Please help me correct a closing speech? I was asked to write a closing speech for my supervisor in the dissertation defense. Please help me make it sound beautiful. Thank you so much! Ladies and Gentlemen, Thank you so much for taking time out to attend the dissertation defense for doctoral students of 2010. I also appreciate the presence of the dissertation committee and their invaluable comments. I remember Da vinci once said “Poor is the pupil who does not surpass his master”. I am just so glad that I did not see that happen here. All 4 of the doctoral students have done a great job in their study. I truly understand how much effort they have made and how much hardship they have been through. So they all deserve to be awarded a doctoral degree. Congratulations! Today is the day for them to enter into a real world and start a new career. I hope they can keep making progress and do their best to serve the patients. Once again, thank you all for coming. Good luck!

Please help me with an opening speech! I am going to give an opening speech for a academic conference soon. Here is the draft of my speech. This is my first time to do this. Please help me pecfect the speech. Thank you so much! Professor Zhao, professor Gross, dear fellows, ladies and gentlemen, good morning. On behalf of the cardiovascular department of our hospital, we are greatly honored and pleased to welcome you all to the Conference on Contrast Induced Nephropathy (CIN). As we know, CIN is the third most common cause of in-hospital acute renal failure, and is associated with long-term mortality rates, major adverse cardiac events, and the risk of undergoing renal dialysis. With rapid increases in the number of diagnostic imaging and interventional therapies, CIN has become a healthcare burden for governments and a challenge for interventionists. However, plenty of doctors practicing in intervention and imaging are not aware of the importance of CIN, and many issues concerning CIN still remain unclear and need to be solved. To raise awareness of CIN, this conference offers you a unique opportunity to gather here to share experiences and discuss evolving strategies for CIN, which definitely will result in the improved outcomes for our patients. It is our great pleasure and privilege to have Professor David Zhao from the United States and Professor Peter Gross from Germany to join us for this conference. Professor David Zhao is the director of the Cardiac Cath Lab and interventional cardiology in Vanderbilt Heart Institute. He is one of the pioneering cardiologists in the field of percutaneous circulatory devices. Today he will give us a lecture on ‘State of Art Interventional Cardiology: 2010 and Beyond’. Professor Peter Gross is the chairman of nephrology section at the Universitätsklinikum. He has served in leadership roles in many professional societies and scholarly journals. Today he will give us a lecture on ‘New Advances in CIN’. There is no doubt that their lectures will bring us latest progress both in interventional cardiology and CIN. With a large number of participants, we are sure that this conference will be a memorable, highly educational, and “not-to-be-missed” event. We hope that this conference will help you better understand the CIN and obtain the knowledge on the prevention and treatment of it. We truly value your participation and support for this conference. Thank you so much for coming and for your attention. Thank you!

Please help me correct the following questions? I am going to interview a famous cardiologist next week. Here are the questions i am going to ask him. Are there any grammatic errors or incorrect use of words? Any ideas about what can be asked in the interview? Thank you! 1.As the idea of evidence-based medicine has been accepted, we follow guidelines to make clinical decisions. However, there are many guidelines from different organizations in Europe, America, or Asia. Considering the differences in the quality of health care, patients, and economic conditions in those places, is it appropriate to apply European or American guidelines to daily practice in China? 2.You are the former president of ACC and the first interventionist to hold that position. You have also served in leadership roles in many professional societies and scholarly journals. What kind of advice would you give to Chinese doctors on researching and writing? 3.You are one of the best interventionists in the world and have trained a lot of doctors in interventional cardiology for the past decades. What do you think is the best way for young doctors to become fully qualified interventionists? 4. What do you think is going to be the biggest breakthrough in the field of interventional cardiology in the near future?
