    Abstract The recurring outbreaks of Drupella snails are a significant threat to coral reef ecosystems on a global scale. However, research on Drupella snails is currently very fragmentary. This article explores the ecological impacts and mitigation methods of Drupella snails and its outbreaks, and draws the following main conclusions. 1) Drupella snails inhabit the tropical oceans of the Indo-Pacific, utilizing their specialized radula to feed on coral polyps, and they predominantly spawn during summer, attaching egg capsules onto coral skeletons. 2) An outbreak of Drupella snails is defined by a density of > 2 ind/m2, but large aggregations alone do not necessarily indicate an outbreak. 3) The damage of coral reef ecosystem is the primary cause of Drupella snail outbreaks, with the hypotheses of “terrestrial nutrient input” and “overfishing of predator” being widely accepted but not fully explaining all outbreak events. 4) Countering Drupella snail outbreaks involves improving the health of coral reef ecosystems, protected areas, biological control and manual removal, though manual removal is the most direct and effective in short-term. 5) The understanding of the physiological and ecological characteristics of Drupella snails is inadequate at present, with larval development and population ecology being areas of particular under-investigation. 6) Studies of Drupella snail outbreaks have focused mainly on mid-outbreak stages, with little attention to early warnings beforehand or adverse outcomes afterwards. Despite significant challenges, addressing knowledge gaps in the biology of Drupella snails is crucial to determine the true causes of their outbreaks and identify corresponding solutions.

    Abstract The role of tourism in social and economic development and stabilizing the Olympic legacy has been widely discussed. Beijing is the first “Dual-Olympic City”. For the first time, the Beijing Winter Olympics has adopted a model of three competition areas, which has attracted much attention to the study of its tourism legacy. In the legacy plan, the construction of the “Beijing-Zhangjiakou Sports Culture and Tourism Belt” was proposed. The development of ice and snow tourism and the cultivation of the ice and snow tourism market is also reflected in many policy documents and government actions. The scientific planning before the competition laid a good foundation for the sustainable development of its ice and snow tourism heritage. This research combines Olympic legacy research with tourism destination theory, and focuses on ice and snow tourism directly related to the Winter Olympics and the significance of pre-event planning for legacy protection. At the same time, the improvement of the quality of ice and snow tourism destinations is embedded in the pre-Olympic legacy, and opinions and suggestions on how to ensure the stability of the legacy after the games are given. This study uses the literature review method and the second-hand materials survey research method, then through establishing a tourism legacy pre-game evaluation model and the use of geographic information, government reports, policies, publicly released statistics and news reports, etc.. It explores the legacy of the Beijing 2022 Winter Olympics and Paralympics, aiming to lay the foundation for preserving the continuous value of the ice and snow tourism legacy during and after the Olympics. The results indicate that the Beijing Winter Olympics has made relatively complete plans and reliable progress in both tangible and intangible legacy. Complete tourism infrastructure, an optimistic sport and cultural atmosphere, and the improvement of residents' health concept and sports awareness have become boosters for the development of ice and snow tourism in the Beijing-Zhangjiakou region.

    Abstract Chongli is one of the venues for the Beijing 2022 Winter Olympics. Since 2009, the government of Chongli has emphasized the development of a tourism strategy, which gradually contributed to alleviating regional poverty. With data collected from 2009 to 2019, ski tourism and the regional economy in Chongli were analyzed using the Coupling Coordination Degree (CCD) Model. This analysis indicated, first, there were three stages in the relationship between ski tourism and the regional economy in Chongli, including weak coordination (2009–2011), starting coordination (2012–2015), and strong coordination (2016–2019). Second, sport tourism, such as ski tourism, is likely to contribute to the regional economy and alleviate poverty. Third, the case of Chongli illustrates that policy and sports events are significant for helping a place to develop sports tourism, in addition to making full use of local resources. Finally, the development of skiing tourism has had a positive impact on citizens' and farmers' incomes, though it may have impacted citizens more. This research suggests that regional resources are essential for the development of sport tourism and the promotion of regional economies. Developing regions should seize the bonus period of sports events and policies. More attention should be paid to the differences between urban citizens and farmers in order to establish a better redistribution system. Considering the climatic factors, more studies need to analyze the sustainability of ski tourism in developing regions.

    Abstract This study uses geographic information systems (GIS) and geographical detector techniques to explore the national and regional pattern of the spatial distribution of China’s ski resorts, and quantitatively identifies the main factors that influence their location. Results show that although China’s ski areas are geographically clustered, ski resorts are more likely to be located at high latitudes (northeast and northwest China) than at low latitudes (central and south China). Among the most influential factors are the winter sporting mega-events that explain 70% of the location of China’s ski areas; the 2022 Winter Olympics accounted for 14%. The main factors that contribute to the distribution of ski areas depend on the regions and types of ski resorts. Implications for the ski resorts industry, such as the different practice for hot and cold spot areas of China’s ski resorts, and the future development direction of ski industry, are discussed.

    Abstract BACKGROUND: High‐quality eggs in unified packaging are desired by egg production enterprises. Automatic orientation apparatus is frequently used to orient eggs uniformly to pointed‐end‐down position for packaging. However, such apparatus may not work accordingly if the eggs are stored under improper methods or for excessive storage time. To study the effect of egg freshness on the efficiency of automatic orientation process, the relationship between egg freshness and its orientation motions was investigated under different storage conditions. RESULTS: The results showed that as the storage time increased, centroid position and pointed‐end‐down turnover ratio decreased; other parameters such as eggs' obliquity at stationary state, horizontal deflection angle, speed, acceleration of axial motion, side‐slip angle and rolling distance increased. However, the effects of storage time on the guiding distance of the guide rod were not apparent. In addition, the higher the storage temperature, the greater the changes of the final orientation states of eggs on the conveyor line. If the eggs were to be oriented uniformly, they should be stored for less than 25, 16, 10 and 7 days at 10 °C, 18 °C, 26 °C and 34 °C, respectively, under a relative humidity of 75%. CONCLUSION: The experimental results presented in this paper are very useful for quality control and quality assurance in egg production enterprises. © 2017 Society of Chemical Industry

    Abstract Mutation of CFTR (cystic fibrosis transmembrane conductance regulator) leads to cystic fibrosis (CF). Patients with CF develop abnormalities of blood platelets and recurrent lung inflammation. However, whether CFTR-mutated platelets play a role in the development of lung inflammation is elusive. Therefore, we intratracheally challenged wildtype and F508del (a common type of CFTR mutation) mice with LPS to observe changes of F508del platelets in the peripheral blood and indexes of lung inflammation (BAL neutrophils and protein levels). Furthermore, we investigated whether or not and how F508del platelets modulate the LPS-induced acute lung inflammation by targeting anti-platelet aggregation, depletion of neutrophils, reconstitution of bone marrow or neutrophils, blockade of P-selectin glycoprotein ligand-1 (PSGL-1), platelet activating factor (PAF), and correction of mutated CFTR trafficking. We found that LPS-challenged F508del mice developed severe thrombocytopenia and had higher levels of plasma TXB2 coincided with neutrophilic lung inflammation relative to wildtype control. Inhibition of F508del platelet aggregation or depletion of F508del neutrophils diminished the LPS-induced lung inflammation in the F508del mice. Moreover, wildtype mice reconstituted with either F508del bone marrow or neutrophils developed worse thrombocytopenia. Blocking PSGL-1, platelet activating factor (PAF), or rectifying trafficking of mutated CFTR in F508del mice diminished and alveolar neutrophil transmigration in the LPS-challenged F508del mice. These findings suggest that F508del platelets and their interaction with neutrophils are requisite for the development of LPS-induced lung inflammation and injury. As such, targeting platelets might be an emerging strategy for dampening recurrent lung inflammation in cystic fibrosis patients.

    Abstract CFTR (cystic fibrosis transmembrane conductance regulator) is expressed by both neutrophils and platelets. Lack of functional CFTR could lead to severe lung infection and inflammation. Here, we found that mutation of CFTR (F508del) or inhibition of CFTR in mice led to more severe thrombocytopenia, alveolar neutrocytosis and bacteriosis, and lower lipoxin A4/MIP-2 (macrophage inhibitory protein-2) or lipoxin A4/neutrophil ratios in the BAL (bronchoalveolar lavage) during acute E. coli pneumonia. In vitro, inhibition of CFTR promotes MIP-2 production in LPS-stimulated neutrophils; however, lipoxin A4 could dose-dependently suppress this effect. In LPS-induced acute lung inflammation, blockade of PSGL-1 (P-selectin glycoprotein ligand-1) or P-selectin, antagonism of PAF by WEB2086, or correction of mutated CFTR trafficking by KM11060 could significantly increase plasma lipoxin A4 levels in F508del relevant to wildtype mice. Concurrently, F508del mice had higher plasma platelet activating factor (PAF) levels and PAF-AH activity compared to wildtype under LPS challenge. Inhibiting hydrolysis of PAF by a specific PAF-AH (PAF-acetylhydrolase) inhibitor, MAFP, could worsen LPS-induced lung inflammation in F508del mice compared to vehicle treated F508del group. Particularly, depletion of platelets in F508del mice could significantly decrease plasma lipoxin A4 and PAF-AH activity and deteriorate LPS-induced lung inflammation compared to control F508del mice. Taken together, lipoxin A4 and PAF are involved in E. coli or LPS-induced lung inflammation in CFTR-deficient mice, suggesting that lipoxin A4 and PAF might be therapeutic targets for ameliorating CFTR-deficiency deteriorated lung inflammation.
