| 1 | Clinical evaluations of mineralized collagen in the extraction sites preservation显示文摘The purpose of this study was to explore the different effects between biomimetic mineralized collagen(MC)and ordinary physically blended hydroxyapatite/collagen(HA/Col)composite in evaluating new bone formation and regenerated bone height in human extraction sockets.Thirty-four patients who cannot retain teeth caused by trauma or decay were randomly selected from Department of Stomatology of Dongzhimen Hospital from December 2013 to December 2014.The patients were randomly divided into two groups.After the operation of tooth extraction,17 patients were implanted with biomimetic MC(MC group),and other 17 patients were implanted with ordinary physically blended nHA/Col composite(nHA/Col group).X-ray positioning projection by auto-photographing was taken to test the distance between the lowest position and the neighboring CEJm-CEJd immediately,1 month and 3 months after the operation.The height of new bone formation of the MC group was significantly higher than the nHA/Col group.Biomimetic MC showed better clinical outcomes in the bone formation for extraction site preservation and would have broad application prospect in the field of oral and maxillofacial surgeries. | Lu Feng Liang Zhang Yun Cui Tian-Xi Song Zhi-Ye Qiu Xiu-Mei Wang Bao-Sheng Tan | 2016 | Regenerative Biomaterials2016，3，1： | 26 |
| 2 | 同种异体牙源性骨移植材料修复兔颅骨缺损的实验研究显示文摘目的通过组织学检测评估兔同种异体牙源性骨移植材料的成骨作用,为口腔种植区骨量不足的修复提供质优价廉的修复材料。方法将兔同种异体离体牙制备成骨移植材料。选用成年健康日本长耳兔28只,建立颅骨缺损模型(3个直径为8mm的洞形缺损),植入同种异体牙源性骨移植材料作为实验组、人工骨修复材料作为对照组、空白对照组不植入任何材料。取标本前3 d、7 d向兔腹腔注射四环素,分别于术后4、8、12周取标本,进行大体观察、X线检查、制备硬组织切片及HE染色。结果术后4、8和12周的组织形态学分析表明,实验组和对照组的新骨生成量呈递增趋势,且实验组优于对照组,骨小梁结构更为饱满;空白对照组骨小梁结构稀少且变化不明显。结论同种异体牙源性骨移植材料能够很好地促进骨缺损的修复,且成骨效果优于一些人工骨修复材料。 | 王媛 王稚英 王明 | 2016 | 中国医科大学学报2016，45，12： | 7 |

| 4 | Regenerative engineering and bionic limbs显示文摘Amputations of the upper extremity are severely debilitating, current treatments support very basic limb movement, and patients undergo extensive physiotherapy and psychological counseling. There is no prosthesis that allows the amputees near normal function. With increasing number of amputees due to injuries sustained in accidents,natural calamities, and international conflicts, there is a growing requirement for novel strategies and new discoveries. Advances have been made in technological, material,and in prosthesis integration where researchers are now exploring artificial prosthesis that integrate with the residual tissues and function based on signal impulses received from the residual nerves. Efforts are focused on challenging experts in different disciplines to integrate ideas and technologies to allow for the regeneration of injured tissues,recording on tissue signals and feedback to facilitate responsive movements and gradations of muscle force. A fully functional replacement and regenerative or integrated prosthesis will rely on interface of biological process with robotic systems to allow individual control of movement such as at the elbow, forearm, digits, and thumb in the upper extremity. Regenerative engineering focused on the regeneration of complex tissue and organ systems will be realized by the cross-fertilization of advances over the past 30 years in the fields of tissue engineering, nanotechnology, stem cell science, and developmental biology. The convergence of toolboxes crated within each discipline will allow interdisciplinary teams from engineering, science, and medicine to realize new strategies, mergers of disparate technologies,such as biophysics, smart bionics, and the healing power of the mind. Tackling the clinical challenges, interfacing the biological process with bionic technologies, engineering biological control of the electronic systems, and feedback will be the important goals in regenerative engineering over the next two decades. | Roshan James Cato T.Laurencin | 2015 | Rare Metals2015，34，3： | 1 |
