《医学前沿（英文）》 2011年第5卷第2期页码 123-126 doi: 10.1007/s11684-011-0124-z

摘要： Traditional Chinese medicine (TCM) has become widely used in the treatment of acquired immune deficiency syndrome (AIDS) in China in recent years. In this article, we summarize the recent major developments in human immunodeficiency virus/AIDS (HIV/AIDS) treatment with TCM. The use of TCM is associated with preventing or alleviating HIV-related symptoms, reducing treatment side effects, and improving the quality of life. The potential beneficial effects of TCM should be confirmed through extensive and rigorous trials.

Low-dose CT for lung cancer screening: opportunities and challenges

null

《医学前沿（英文）》 2018年第12卷第1期页码 116-121 doi: 10.1007/s11684-017-0600-1

摘要：

Lung cancer is among the most frequently diagnosed cancers worldwide and the leading cause of cancer death in both males and females. Screening for lung cancer coupled with earlier intervention has long been studied as an approach to mortality reduction. However, minimal progress was achieved until recently, when low-dose spiral computed tomography (LDCT) screening demonstrated a 20% reduction in mortality from lung cancer in a randomized controlled trial (RCT), the National Lung Screening Trial, from the United States. On the basis of this finding, LDCT has been recommended for lung cancer screening in high-risk populations by several clinical guidelines. However, results from the following independent RCTs in Europe failed to show consistent conclusions. In addition, intractable problems gradually emerged with the progress of LDCT screening. This paper summarizes and discusses the main observations and challenges of LDCT screening for lung cancer. Before spreading implementation of LDCT screening, challenges, including high false-positive rates, overdiagnosis, enormous costs, and radiation risk, must be addressed. Complementary biomarkers and technical improvement are expected in the field of lung cancer screening in the near future.

Opportunities and challenges for a Golden Age of chemical engineering

Phillip R. WESTMORELAND

《化学科学与工程前沿（英文）》 2014年第8卷第1期页码 1-7 doi: 10.1007/s11705-014-1416-z

摘要： Chemical engineering is entering a new Golden Age of practice, thought, and impact, accompanied by great new opportunities and challenges. Five aspects mark this development: a new abundance of hydrocarbons; the evolution of biology into a molecular science; the ubiquity of powerful computational tools; the trend in manufacturing to be more process-oriented; and the systems approach that is part of ChE education from its first stages. There are important technical challenges, including technology creation and environmental impact, but just as important are new appreciation for and attention to challenges that require societal dialogues about complexity, uncertainty, and evolving and sometimes contradictory requirements. Crucial to all these impacts is enhancing the identity of what the profession is. That must be based on recognizing that the core of chemical engineering is applying molecular sciences to create value and advance the quality of life.

BIOINSECTICIDES AS FUTURE MAINSTREAM PEST CONTROL AGENTS: OPPORTUNITIES AND CHALLENGES

《农业科学与工程前沿（英文）》 2022年第9卷第1期页码 82-97 doi: 10.15302/J-FASE-2021404

摘要：

Bioinsecticides are naturally-occurring substances from different sources that control insect pests. Ideal bioinsecticides should have low toxicity to non-target organisms. They should also be easily degraded in sewage treatment works and natural environments, highly effective in small quantities and affect target pests only. Public concerns about possible side-effects of synthetic pesticides have accelerated bioinsecticide research and development. However, to develop bioinsecticides into mainstream products, their high production costs, short shelf-life and often uncertain modes of action need to be considered. This review summarizes current progress on bioinsecticides which are categorized as biochemical insecticides and their derivatives, plant-incorporated protectants, and microbial bioinsecticides. The current constraints that prevent bioinsecticides from being widely used are discussed and future research directions are proposed.

伊朗铁路建设市场需求、机遇及挑战评估：基于中资企业视角

雷洋,黄承锋,张学进

《中国工程科学》 2019年第21卷第4期页码 124-130 doi: 10.15302/J-SSCAE-2019.04.021

摘要：

伊朗铁路经过百年发展，在伊朗综合运输体系中占据重要地位。为满足伊朗国内经济社会发展需要，发挥国际交通枢纽的区位优势，伊朗制定了为期10 年的铁路发展规划，计划到2025 年，铁路网络既有线路全部实现电气化改造，复线率提升至100%，并且实现铁路里程翻番目标。伊朗铁路提升计划为中资企业进入伊朗工程建设市场提供了利好和机遇，中资企业参与伊朗铁路提升计划也面临“伊核协议”不确定性、营商环境不佳、铁路建设领域大国“角逐”，以及技术标准选择偏好等四方面的挑战。研究建议，中资企业参与伊朗铁路建设市场，不仅需要敏锐捕捉机会，也需要谨慎评估存在的风险；结合国际政治经济形势，综合权衡成本和收益，进行理性决策，在响应“一带一路”倡议过程中，稳健地实施“走出去”战略。

Progress of forest certification in China

Wenming LU, Maharaj MUTHOO

《农业科学与工程前沿（英文）》 2017年第4卷第4期页码 414-420 doi: 10.15302/J-FASE-2017185

摘要： The Chinese Government is committed to forest certification as a market-based instrument to promote sustainable forest management. Forest certification includes a number of regulations, rules and policy paradigms related to certification and there are numerous challenges facing the uptake of forest certification in China. In particular, the ban on commercial logging in natural forests implemented by the Natural Forest Protection Program has resulted in little demand for forest certification of natural forest management units. However, there are also certification opportunities, such as the certification of non-timber forest products that benefit local communities who depend on forests for the goods and services they provide. This paper provides an overview of progress in forest certification in China, including its development history, organizational structure, scheme documents, certification scopes and standards, accreditation, certification bodies and auditors, and certification logos. The paper also focuses on government support for the supervision and management of forest certification through policy incentives, including the potential government procurement and subsidy policies for certified forest products. Finally, the paper analyzes certified non-timber forest products as an example of the value of certification to promote sustainable forest management and how the concept of forest certification can be used to add value to forests and ensure they are responsibly and sustainably managed. In general, forest certification in China has a clear role in sustainable forest management, both for timber and non-timber forest products.

Challenges and opportunities in improving left ventricular remodelling and clinical outcome following

《医学前沿（英文）》 2021年第15卷第3期页码 416-437 doi: 10.1007/s11684-021-0852-7

摘要： Over the last half century, surgical aortic valve replacement (SAVR) has evolved to offer a durable and efficient valve haemodynamically, with low procedural complications that allows favourable remodelling of left ventricular (LV) structure and function. The latter has become more challenging among elderly patients, particularly following trans-catheter aortic valve implantation (TAVI). Precise understanding of myocardial adaptation to pressure and volume overloading and its responses to valve surgery requires comprehensive assessments from aortic valve energy loss, valvular-vascular impedance to myocardial activation, force-velocity relationship, and myocardial strain. LV hypertrophy and myocardial fibrosis remains as the structural and morphological focus in this endeavour. Early intervention in asymptomatic aortic stenosis or regurgitation along with individualised management of hypertension and atrial fibrillation is likely to improve patient outcome. Physiological pacing via the His-Purkinje system for conduction abnormalities, further reduction in para-valvular aortic regurgitation along with therapy of angiotensin receptor blockade will improve patient outcome by facilitating hypertrophy regression, LV coordinate contraction, and global vascular function. TAVI leaflet thromboses require anticoagulation while impaired access to coronary ostia risks future TAVI-in-TAVI or coronary interventions. Until comparable long-term durability and the resolution of TAVI related complications become available, SAVR remains the first choice for lower risk younger patients.

从资源共享到服务共享：透明计算的机遇与挑战

张尧学,周悦芝

《中国工程科学》 2009年第11卷第8期页码 10-17

摘要：

随着计算机和网络技术以及应用的不断快速发展，计算模式从最初的以主机计算为主，发展到以桌面(PC)计算为主，再发展到现在的以网络计算为主，乃至普适计算。然而，迄今为止的计算模式还是遵循以单机或单机联合为基础的单机思维模式，因此，目前的计算模式还是一种以“资源共享”为主要特征的计算。在网络和普适计算的新时代，用户关心的主要是服务和服务共享，计算机也将从以“资源共享”为特征的计算过渡到以“服务共享”为特征的计算。笔者提出一种适应于“服务共享”的计算模式——透明计算，并对其概念、体系结构及相关关键技术进行介绍。此外，还对透明计算的未来发展及影响进行展望。
