1The ReaxFF reactive force-field: development, applications and future directions显示文摘The reactive force-field(ReaxFF)interatomic potential is a powerful computational tool for exploring,developing and optimizing material properties.Methods based on the principles of quantum mechanics(QM),while offering valuable theoretical guidance at the electronic level,are often too computationally intense for simulations that consider the full dynamic evolution of a system.Alternatively,empirical interatomic potentials that are based on classical principles require significantly fewer computational resources,which enables simulations to better describe dynamic processes over longer timeframes and on larger scales.Such methods,however,typically require a predefined connectivity between atoms,precluding simulations that involve reactive events.The ReaxFF method was developed to help bridge this gap.Approaching the gap from the classical side,ReaxFF casts the empirical interatomic potential within a bond-order formalism,thus implicitly describing chemical bonding without expensive QM calculations.This article provides an overview of the development,application,and future directions of the ReaxFF method.Thomas P Senftle Sungwook Hong Md Mahbubul Islam Sudhir B Kylasa Yuanxia Zheng Yun Kyung Shin Chad Junkermeier Roman Engel-Herbert Michael J Janik Hasan Metin Aktulga Toon Verstraelen Ananth Grama Adri CT van Duin 2016npj Computational Materials2016,,1:22
2早产儿视网膜病变早期治疗(ETROP)过程中发生视网膜脱离眼的预后显示文摘研究对象:在早产儿视网膜病变早期治疗(ETROP)研究中因早产儿视网膜病变(ROP)而发生视网膜脱离眼的结构以及功能改变。 研究方法:加入ETROP研究中的新生儿患有双眼高危阈前ROP,随即对其一眼进行早期治疗,另一眼进行传统治疗。只有单眼患病的早产儿。随机对高危阈前ROP眼进行早期治疗或传统治疗。当视网膜脱离被发现时。研究者会继续观察患者病变或对其行视网膜玻璃体手术(如巩膜加压术以肜或者玻璃体切除术)。在矫正9月龄时,对患者视网膜状况进行评估并使用条栅视敏度(grating acuity)对患儿视力进行检测。 研究结果:401例高危阈前ROP患者加入了ETROP研究。63例患者(89只眼)发生了视网膜脱离。对其中56例患者(78只眼)进行了随访。21例患者(38%)的视网膜脱离发生于双眼。其中30只眼分级为4A,14只眼为4B,16只眼为5级。余下的18只视网膜脱离眼未进行分级。对11例患者(12只眼)监控病情变化,52例患者(66只眼)行玻璃体视网膜手术。行玻璃体切除伴或不伴有巩膜加压术的56只眼中有17只(30%)在患者9月龄时保持或达到了黄斑复位;仅行巩膜加压术的10只眼中,6只(60%)达到;未行手术的12只眼中,2只(17%)达到。78只眼中有13只(17%)达到了较好的视力水平(I〉1.85cycles/degree)。达到正常视力水平(≥3.70cycles/degree)的6只眼的视网膜脱离分级均为4A(其分别为6只未行手术眼中的1眼,6只行巩膜加压术眼中的3眼。18只行玻璃体切除术眼中的2眼)。对11只视网膜脱离达5级的患眼行玻璃体视网膜手术。 治疗结果为6只眼无光感,3只眼仅有光感,2只眼只能看清低视力表。结论:在ETROP的研究中,ROP导致视网膜脱离的治疗结果普遍较差。因视网膜脱离行玻璃体视网膜手术的48只眼中,有16只眼黄斑未发生脱离。手术修复4A级视网膜脱离的24只眼中,有5只(21%)在术后达到了正常视力水平。对视网膜脱离5级眼行玻璃体视网膜手术可以使其达到结构复位,但功能恢复不佳。Michael X.

4Outsmarting cancer:an international brainstorm in Guangzhou显示文摘Cancer is the most deadly disease in the United States.In developing countries such as China, cancer is increasingly prevalent as a cause of death.The “war against cancer” that was initially declared in the United States has become a global war that requires an alliance of world-wide cancer researchers.As part of such an effort, the Second Guangzhou International Symposium on Oncology was held on May 20-22, 2011, in Guangzhou, China.Chao-Nan Qian 1,2 and Wei Zhang 31 Laboratory of Cancer and Developmental Cell Biology,Van Andel Research Institute,Grand Rapids,MI 49503,USA 2 State Key Laboratory of Oncology in South China,Sun Yat-sen University Cancer Center,Guangzhou,Guangdong 510060,P.R.China 3 Department of Pathology,University of Texas MD Anderson Cancer Center,Huston,TX 77030,USA. 2011Chinese Journal of Cancer2011,30,8:2
