《工程管理前沿(英文)》 2014年 第1卷 第3期   页码 232-240 doi: 10.15302/J-FEM-2014043

摘要: This paper explores the principal motivations and successful experiences of the rapid development of China’s high speed railway. In the perspective of the engineering management practice, the developers have studied and made prospective mid- and long-term railway network planning, including the four east-west and four north-south corridors as the backbone, the interregional urban passenger traffic corridors and the intercity railways, with a planning scale above 16,000 km. Under the overall coordination of the government, a high speed railway technology system has been formed with the China’s characteristics, by the way of sticking to independent innovation, of combining original innovation, collaborative innovation and integrative innovation, and of attaching importance to experimental verification. The target control system and support-guarantee system were established for the high speed railway project, enacting standardized management, strengthening integration test and commissioning, conducting strict acceptance, and achieving construction management experiences on the high speed railway. Finally, this paper proposes such issues worthy of attention and further study, as the improvement of the engineering decision-making management, the enhancement of investment and financing system reform, and the promotion of professionalization and the specialization of engineering project management.

摘要: As the coal-dominated energy structure will remain unchanged in the short term, the sustainable development of the coal industry is still serving as one of the foundations for the sound development of the national economy. The construction of modernized mines based on "four orientations", that is, orientations of scale production, modern technology and equipment, informationized management and professional working team, has been rapidly enhancing its development in the recent decade. However, in the next decade or an even longer period, the industry, with the energy centre shifting to the West of China, will be exposed to new options and development in the layout, structure, model, technology, etc.

摘要:

Circumcision is probably one of the most ancient surgical operations and has been performed more than any other operation. The aim of this study is to assess the prevalence of circumcision in preschool boys and to present an overview of the current practices and complications in Baghdad, Iraq. A statistical survey was conducted at the Central Teaching Hospital for Children in Baghdad, Iraq during the period April 2003 to October 2004. The survey consisted of structured interviews with the accompanying parents while waiting for their children’s routine appointments. A total of 4000 boys were included. 2 443 (61%) were circumcised and the prevalence of circumcision increased from 18% at 6 months of age to reach 92% at 6 years. Only 180 (7.4%) boys had a medical reason while the rest were circumcised for religious reasons. Parents were the only determinant in deciding the time and place of religious circumcision. Circumcision was performed by a doctor in 732 (30%) boys, by a nurse in 1276 (52%) and by a traditional circumciser in 435 (18%). Post-operative complications were encountered in 209 (8.5%) boys. Circumcision is an important surgical procedure that should be performed by trained medical staff in medical institutions. Circumcision performed by medical professionals caused significantly less complications.

New practice in semaglutide on type-2 diabetes and obesity: clinical evidence and expectation

《医学前沿(英文)》 2022年 第16卷 第1期   页码 17-24 doi: 10.1007/s11684-021-0873-2

摘要: Obesity is an important risk factor of type 2 diabetes (T2D), which has become an important factor threatening human health. However, no perfect drug choice for obesity exists. Semaglutide is a kind of human glucagon-like peptide-1 (GLP-1) analog that promotes insulin secretion while inhibiting glucagon secretion through a glucose concentration-dependent mechanism. GLP-1 can also delay stomach emptying and suppress appetite to help lose weight. This review summarizes clinical evidence of the semaglutide effect on T2D and obesity and establishes expectations on future clinical trials for obesity treatment.

摘要:

Despite the current acceleration and increasing leadership of Chinese genetics research, genetics and its clinical application have largely been imported to China from the Occident. Neither genetics nor the scientific reductionism underpinning its clinical application is integral to the traditional Chinese worldview. Given that disease concepts and their incumbent diagnoses are historically derived and culturally meaningful, we hypothesize that the cultural expectations of genetic diagnoses and medical genetics practice differ between the Occident and China. Specifically, we suggest that an undiagnosed diseases program in China will differ from the recently established Undiagnosed Diseases Program at the United States National Institutes of Health; a culturally sensitive concept will integrate traditional Chinese understanding of disease with the scientific reductionism of Occidental medicine.

摘要: The construction industry has long been plagued with a high number of fatalities in the USA. Much safety improvements have been made after the USA Congress passed the Occupational Safety and Health Act in 1970. However, this industry still suffers from a disproportionately high rate of work-related fatalities in comparison to other industries. To provide a holistic view of current construction safety practices and corresponding performance, this paper reviews statistics of construction fatalities and their causes. It then presents efforts led to prevent work-related accidents and injuries by the federal safety agencies and the industry. Additionally, advantages and limitations of current practices in terms of construction safety have been discussed along with promotion of aspects in construction work environment.

摘要:

Grading of Recommendations Assessment, Development, and Evaluation (GRADE) offers a worldwide approach to guideline development for clinical practice. For the clinical practice of acupuncture therapy, 18 evidence-based guidelines have been developed in China using GRADE. In this study, we review the advantages and limitations of the GRADE approach in the guideline development for acupuncture and moxibustion and propose some solutions to these limitations. Scientific advantages of rating the quality of evidence, outcome-centric direction, overall progression to develop recommendations, and strength of recommendations providing specific clinical guidance are the advantages of GRADE. The limitations of GRADE in the development of guidelines for acupuncture and moxibustion include rating the quality of evidence for ancient literature and literature on famous traditional Chinese medicine experts’ experiences and specific guidelines for formulating recommendations from evidence. In the guideline development for clinical practice with acupuncture and moxibustion, we suggest that a specific method should be explored based on the GRADE approach and the characteristics of acupuncture therapy.

Practice and principle of traditional Chinese medicine for the prevention and treatment of COVID-19

《医学前沿(英文)》 doi: 10.1007/s11684-023-1040-8

摘要: Traditional Chinese medicine (TCM) has played an important role in the prevention and treatment of coronavirus disease 2019 (COVID-19) epidemic in China. The integration of Chinese and Western medicine is an important feature of Chinese COVID-19 prevention and treatment. According to a series of evidence-based studies, TCM can reduce the infection rate of severe acute respiratory syndrome coronavirus 2 in high-risk groups. For patients with mild and moderate forms of COVID-19, TCM can relieve the related signs and symptoms, shorten the period of nucleic-acid negative conversion, and reduce conversion rate to the severe form of the disease. For COVID-19 patients with severe and critical illnesses, TCM can improve inflammatory indicators and blood oxygen saturation, shorten the hospital stay, and reduce the mortality rate. During recovery, TCM can improve patients’ symptoms, promote organ function recovery, boost the quality of patients’ life, and reduce the nucleic-acid repositive conversion rate. A series of mechanism research studies revealed that capability of TCM to treat COVID-19 through antiviral and anti-inflammatory effects, immune regulation, and protection of organ function via a multicomponent, multitarget, and multipathway approach.

摘要: This paper introduces the design idea and technique utilized in the Library of Shandong Transportation College, which ranked 1st in the 2nd National Green Buildings Innovation Award in China in March 2007 due to its low cost and climate-oriented green strategy during its design and construction phase, including land saving, energy efficiency, water conservation, and so on. Originally, the place was a landfill site with an odor pool. After reconstruction, it was changed into the construction site of the library with an area of 7000m and a scenery pond. With the integrated use of passive shading, daylighting, ventilation with atriums, high-insulation materials, underground duct ventilation, and the substitution of cooling tower with the pond water, the HVAC load design indexes are 59 W/m and 21.8 W/m for space cooling and heating, respectively, much lower than the newly issued Chinese energy efficient design code for public buildings. Moreover, a set of measures is utilized for water conversation, material saving, and improvement of indoor environmental quality. After three years of operation, the real effect has been validated by electricity meter and field measurement. The total initial cost for the building with the above mentioned integrated technologies was only RMB 2150 per square meter, which was worth spending in China due to the climatic adaptability and the relative low cost.
