GRASSLAND AGRICULTURE IN CHINA—A REVIEW

《农业科学与工程前沿（英文）》 2021年第8卷第1期页码 35-44

摘要：

• Grassland-based livestock production systems cover large areas in China.

• China is facing degradation of rangeland and has great shortage of forage.

• Five types of mixed crop-livestock systems in China described.

• Improving crop–livestock integration requires S&T and policy supports.

Interactions between crops and livestock have been at the core of the evolution of many agricultural systems. In this paper, we review the development and characteristics of mixed crop-livestock systems, with a focus on grassland-based systems, as these cover large areas in China, and face several challenges. Following the transition from the original hunting and foraging systems to a sedentary lifestyle with integrated crop-livestock production systems some 8000 years ago, a range of different mixed systems have developed, depending on rainfall, solar radiation and temperature, culture and markets. We describe 5 main types of integrated systems, (1) livestock and rangeland, (2) livestock and grain production, (3) livestock and crop – grassland rotations, (4) livestock, crops and forest (silvo-pasture), and (5) livestock, crops and fish ponds. Next, two of these mixed systems are described in greater detail, i.e., the mountain-oasis-desert system and its modifications in arid and semi-arid regions, and the integrated crop-livestock production systems on the Loess Plateau. In general, crop-livestock interactions in integrated systems have significant positive effects on crop production, livestock production, energy use efficiency and economic profitability. We conclude that improved integration of crop-livestock production systems is one of the most important ways for achieving a more sustainable development of animal agriculture in China.

Status of hyperhomocysteinemia in China: results from the China Stroke High-risk Population Screening

《医学前沿（英文）》 2021年第15卷第6期页码 903-912 doi: 10.1007/s11684-021-0871-4

摘要： A nationwide survey was conducted from October 2018 to September 2019 to assess the prevalence of hyperhomocysteinemia (Hhcy) and its influencing factors in China. A standardized questionnaire was used to collect information. Hhcy was defined as the level of serum homocysteine (HCY)

≥

15.0 µmol/L. The H-type hypertension (HHYP) was defined as hypertension with an elevated serum HCY (

≥

15.0 µmol/L). Finally, 110 551 residents

≥

40 years of age from 31 provinces in the mainland of China were included. Overall, the median serum HCY level was 10.9 µmol/L (interquartile range 7.9–15.1). A total of 28 633 participants (25.9%) were defined as Hhcy. The Hhcy prevalence ranged from 7.9% in Shanghai to 56.8% in Tianjin. The data showed that serum HCY levels were associated with age, male gender, cigarette smoking, hypertension, diabetes, ethnicity, endurance in exercise (inverse), and fruit and vegetable intake (inverse). In addition, 15 486 participants were defined as HHYP, and the rate was 14.0%. HHYP was an independent predictor of stroke with an adjusted odds ratio of 1.752 (95% CI 1.338–2.105). The geographical distribution pattern of the Hhcy epidemic reflects dynamic differences, and national strategies should be carried out to further improve the care of patients with Hhcy across China.

EGG PRODUCTION IN CHINA: CURRENT STATUS AND OUTLOOK

Ning YANG

《农业科学与工程前沿（英文）》 2021年第8卷第1期页码 25-34 doi: 10.15302/J-FASE-2020363

摘要： Eggs are one of the most nutritious and affordable animal products worldwide. From 1985, egg production in China has retained the leading place in the world. A total of 33 Mt of eggs were produced in 2019 representing ˃ 40% of the world total production. Egg production in China is characterized by diversity in several aspects, including layer breeds, products and production systems. New breeds and synthetic lines are developed to improve the genetic potentials of egg production and feed efficiency of layers. In the past, layer farms were run mostly by small households with 100 to 1000 layers per farm. Over the past decades, egg production in China has developed toward standardization and expansion of production systems, and many of these modern intensive farms raise millions of layers. Although the Chinese egg products maintain strong competitiveness over other animal products and imported egg products, the egg industry will grow at a slower pace compared to the past. Chinese consumers are more concerned about the quality and safety of eggs and egg products, as well as the environmental issues related to animal production, which presents challenges for the Chinese egg industry.

Achievements of the national malaria control and elimination program in the People’s Republic of China

《医学前沿（英文）》 2023年第17卷第1期页码 85-92 doi: 10.1007/s11684-021-0917-7

摘要： In 2017, China achieved the target of zero indigenous malaria case for the first time, and has been certified as malaria free by World Health Organization in 2021. To further summarize the historical achievements and technical experiences of the elimination program, a project on the Roadmap Analysis and Verification for Malaria Elimination in China was carried out. Results of the project were compiled and published as the Atlas of Malaria Transmission in China (The Atlas). The Atlas using modern digital information technologies, has been supported by various data from 24 malaria endemic provinces of China since 1950, to assess the changes in malaria epidemic patterns from 1950 to 2019 at national and provincial levels. The Atlas is designed as two volumes, including a total of 1850 thematic maps and more than 130 charts, consisting of introductory maps, thematic maps of malaria epidemic and control at national and provincial levels. It objectively and directly shows the epidemic history, evolution process, and great achievements of the national malaria control and elimination program in China. The Atlas has important reference value for summing up historical experience in the national malaria elimination program of China, and malaria control and elimination in other endemic countries in the world.

Laboratory diagnosis for malaria in the elimination phase in China: efforts and challenges

《医学前沿（英文）》 2022年第16卷第1期页码 10-16 doi: 10.1007/s11684-021-0889-7

摘要： Malaria remains a global health challenge, although an increasing number of countries will enter pre-elimination and elimination stages. The prompt and precise diagnosis of symptomatic and asymptomatic carriers of Plasmodium parasites is the key aspect of malaria elimination. Since the launch of the China Malaria Elimination Action Plan in 2010, China has formulated clear goals for malaria diagnosis and has established a network of malaria diagnostic laboratories within medical and health institutions at all levels. Various external quality assessments were implemented, and a national malaria diagnosis reference laboratory network was established to strengthen the quality assurance in malaria diagnosis. Notably, no indigenous malaria cases have been reported since 2017, but the risk of re-establishment of malaria transmission cannot be ignored. This review summarizes the lessons about malaria diagnosis in the elimination phase, primarily including the establishments of laboratory networks and quality control in China, to better improve malaria diagnosis and maintain a malaria-free status. A reference is also provided for countries experiencing malaria elimination.

Deepwater Hydrocarbon Exploration in China Seas: Yesterday, Today and Tomorrow

Zhi-gang Zhao,Hai-zhang Yang,Wu Tang,Shi-xiang Liu

《工程管理前沿（英文）》 2016年第3卷第4期页码 390-395 doi: 10.15302/J-FEM-2016059

摘要： Deepwater area has been one of the hottest areas in the global hydrocarbon exploration. However, deepwater hydrocarbon exploration in China started late and mainly concentrated in the South China Sea (SCS) with low level of researches. Although there are some achievements, there are even more challenges. For this reason, this paper reviewed the history of deepwater exploration in China Seas and summarized the current exploration situation. The future directions of deepwater hydrocarbon exploration mainly consist of five aspects: establishing key technology system of complex structure and reservoir seismic acquisition and processing in deepwater areas of SCS, clarifying the development mechanism of high quality source rock and establishing matching assessment technology, studying the formation conditions of favorable reservoir and creating reservoir identification technology, improving accumulation theory of large and medium-sized oil and gas field of deepwater, deepening the researches of petroleum geology conditions of middle and south part of SCS. Simultaneously, the concept of portfolio should be utilized in the exploration process, with economic benefits considered. These understandings will help guiding the future deepwater hydrocarbon exploration in China Seas.
