The cactus pear fruits were under the two conditions of normal and low temperature treatment, logistics packaging by foam mesh bag, foam filler, laminated isolation plate, plastic wrap, a total of 8 kinds of treatments. The influence of different logistics packaging on the quality of cactus pear fruit was studied, by measuring fruit firmness, soluble solid, titratable acid, weight loss rate, juice yield, rate of intact fruit, ethyl alcohol, glucose, vitamin C content before and after logistics transportation, in order to select suitable logistics packaging methods for cactus pear fruits. The results showed that low temperature significantly reduced the quality reduction of cactus pear fruit during logistics transportation. Compared with foam filler, foam mesh bag, laminated isolation plate, logistics packaging by plastic wrap can maintain the firmness of fruit, decrease the content of vitamin C, soluble solid, glucose, juice yield, rate of intact fruit, and reduce the increase of ethanol and weight loss rate. There was no significant effect on titratable acid content of cactus pear fruit by different packing treatments. In summary, low temperature and the use of plastic wrap packaging can improve the quality of cactus pear fruit in logistics transportation. [ABSTRACT FROM AUTHOR]

Objective To review and analyze the literature related to public health events in China from 2003 to 2023, so as to provide reference for predicting, preventing, and responding to future public health events, and to enhance China s capacity to deal with sudden public health emergencies. Methods A total of 2 717 articles related to public health field published between 2003 and 2023 and indexed in databases including SCI, CSSCI, CSCD, and PKU core in China National Knowledge Infrastructure (CNKI) were selected as data sources. The CiteSpace software was utilized to explore research hotspots and trends in the evolution of pathways in the field of public health events. Results The study revealed fluctuations in the number of publications on public health events. Author collaboration was relatively stable, while institutional collaboration intensity was low and interdisciplinary collaboration was limited. Research hotspots included emergency management, sudden events, epidemic prevention and control, infectious diseases, and online public opinion. Research content encompassed the epidemic characteristics, influencing factors, emergency response capabilities, and governance responses to public health events. Research topics went through three stages: exploration of public health theories, system construction, and social governance. Conclusion Future research directions will focus mainly on risk communication, public opinion management, and collaborative governance in public health events. [ABSTRACT FROM AUTHOR]

In the age of information technology, the establishment of a virtual teaching and research platform represents a crucial endeavor in reshaping educational organizations. It plays a pivotal role in advancing the development of university-level programs and fostering talent through collaborative resource sharing and multi-university cooperation. This article focuses on the utilization of the virtual teaching and research platform within national colleges and universities offering applied chemistry programs. The aim is to build a top-tier undergraduate applied chemistry program on a national scale and to explore the C4H4 spirit, inspired by the motto of South-Central Minzu University, which stands for "Clean Heart, Cautious Habit, Comparative Haecceity, and Clever Hands". This exploration takes shape through various teaching and research methodologies, including seminars, experiential exchanges, demonstration lessons, project initiations, achievement showcases, and teacher training. Leveraging virtual teaching and research platform apps and online platforms, collaborative efforts are made to create and share resources such as teaching cases, virtual simulation projects, question banks, paper collections, knowledge graphs, teaching videos, electronic course materials, and data repositories. These collective endeavors aim to enhance students' professional literacy, foster effective learning habits, and promote the development of professional thought processes and practical skills. The ultimate goal is to cultivate well-rounded and high-caliber innovative talents characterized by strong professionalism, a disciplined learning approach, a sharp professional mindset, and exceptional practical abilities, particularly suited for the needs of various nationalities.
