Traditional SILS instruments are adult-sized, single -use and costly. The new technique involves crossing two straight conventional laparoscopic instruments through a single-incision. Since October 2009, over 30 children aged three to 15 have successfully undergone SILS, from simple procedures such as appendectomy to complex ones like splenectomy and nephrectomy. In May 2010, the division successfully performed the world’s first single-incision laparoscopic heminephroureterectomy on a child, which is unprecedented in medical literature. Advanced Eco School System Developed A research team lead by Prof. Zhu Jingxiang of the School of Architecture developed an advanced architectural system for the construction of the New Bud Study Hall in Sichuan in the summer of 2010. The light structure has an earthquake resistance reaching Mercalli Intensity Scale X and an expected life span of over 20 years. The vents are well-positioned and the stack effect is manipulated carefully to keep indoor space cool in summer and warm in winter. A wind turbine is used to provide clean energy to power LED lights, keeping the total energy consumed for lighting to as low as 1.2 KW. The three classrooms and one reading space compactly housed in the structure are divided by translucent partition walls which can block noise without hindering light penetration. Over 90% of the components of the 260 m 2 single-storey building are prefabricated in factories, reducing the time taken to assemble the structure to only 14 days. The system is an ideal option for buildings in areas threatened by natural disasters or stricken areas needing reconstruction.
