SUMMARY OF LEARNING IN JAPAN
　 It’s a great honor for me to be subsidized by the Japanese Urological Association and studied in the department of urology, Okayama University for a month, between January 21th and February 20 th.
　During this precious period, I visited many urological operations, including laparoscopic surgery, da vinci Robert-assisted surgery as well as the first case of REIC gene therapy. My specific impression on surgery-visiting will be detailed as follows:

REIC gene therapy
　I remembered clearly that it was January 25th, a Tuesday, when I stepped into the operating room in Okayama University Hospital and met Professor Kumon, who looked excited and said “It’s a big day for us today!” I knew from him that the first case of REIC gene therapy agent would be applied for a prostate cancer patient after a while. When I entered the operating room, many people had been waiting there, including doctors, nurses and journalists. Professor Kumon and Professor Nasu injected REIC gene agent into the local lesion of a 70yr old prostate cancer patient smoothly under the guidance of ultrasound. This was the first time to exert the gene therapy drug into the body of a patient, which indicated that REIC gene therapy drug, produced and developed in Okayama University, had stepped into clinical trial phase!

Da vinci Robert-assisted surgery
　Many times heard but never seen! It was really impressing when I first saw the da vinci Robert-assisted system in Okayama university hospital. In the radical prostatectomy surgery, many advantages had been displayed by Robert-assisted system: clear vision of the surgical field, better stability for mechanical arms, small amount of bleeding and so on. However, it is not easy to manipulate the Robert-assisted system skillfully and the cost of money is huge both for patients and for the government, which limited its utilization in China.

Laparoscopic surgery
　Laparoscopic surgery is popular in the field of urology and it is replacing open surgeries gradually. In developed regions of China, such as Beijing, Shanghai and Guangzhou, the use of laparoscopic surgery is similar with that in Japan. But one difference impressed me during my visit in Okayama University Hospital was that: young surgeons were given much more chance to operate independently and the older experienced surgeons showed great deal of patience in directing them.
　Besides visiting of surgery operations, I also participated in two important meetings during my stay in Okayama:

Asian cooperative research meeting
　On February 17th, “An Asia-wide translational research on high-risk group detection based on ms-SNP and IL-12 gene therapy for prostate cancer” research meeting was hold. Researchers from Japan, China, Korea and Singapore presented their research results respectively. On behalf of Professor Na in Peking University, China, I presented our results on SNP research and our application work for IL-12 gene therapy in China.

Asian Study Okayama’11
　The symposium “Asian Study Okayama’11, from Asian to the World” was held on February 18th .  Professor Kumon organized the meeting and delivered keynote lecture”Five Years of Asian Study Okayama Symposia”.  The topic was gene therapy in Asian and many knowledgeable reports had been given by speakers from different countries. Through the symposium, I got an in-depth understanding on current situation and future directions of gene therapy.
　At last, I would like to thank the Japanese Urological Association and Okayama University, for giving me such a great chance to study in Japan. Hope our exchanges and cooperation will be strengthened in the future!
