Under the background of the era of rapid development of artificial intelligence, great changes have occurred in the field of accounting, and the education of accounting majors in colleges and universities is facing new challenges and opportunities. This paper analyzes the situation of colleges and universities in cultivating accounting students' ability to count business, including the use of case study and literature combination, and discusses the changes in the industry demand, the current situation of education reform in colleges and universities, and the corresponding strategy suggestions. The study finds that although colleges and universities have taken a variety of reform measures, there is still the problem of mismatch with the speed of change in the industry. Colleges and universities should make efforts in updating education concepts, optimizing curriculum, strengthening faculty development and innovating teaching methods in order to cultivate accounting professionals who meet the needs of the times and promote economic and social development.
This study aimed to investigate the polymorphism of porcine-origin Ral guanine nucleotide dissociation stimulator (RalGDS) in LLC-PK1 cells using RT-PCR and sequencing. Our results revealed seven polymorphisms in the RalGDS gene, including insertions, deletions, and frameshift mutations. These variations may significantly alter the protein structure and function of RalGDS, potentially influencing its role in Ral GTPase-mediated signaling pathways. This work provides foundational insights into the genetic diversity of porcine RalGDS and its implications for pig physiology and economically important traits.
Dry reforming of methane (DRM) process under photo-thermal catalysis attracts more and more attentions due to its fast reaction rate and higher conversion compared with traditional thermal catalysis techniques. However, most of current researches were mainly focused on the development of new photo-thermal catalysts, while the kinetic characteristics of DRM reaction under photo-thermal conditions was seldomly studied and discussed. Aiming this point, the performances of a Pt/mesoporous-TiO2 catalyst were investigated under different reaction conditions (reaction temperature, light irradiation intensity and molar ratio of feed gases) in this paper. It was found that (1) Increasing the light intensity and reaction temperature would have a positive effect on the DRM reaction, increasing the formation rates of two products and H2/CO ratio; (2) The intensification ratio of formation rates of light/dark condition would decrease when temperature gets higher; (3) Under dark conditions, increasing the partial pressure of CO2 was not conducive to the progress of the DRM reaction; (4) With light conditions, an appropriate increase in the partial pressure of CO2 would be beneficial to the progress of the DRM reaction and to improve the yield of the product. To explain the variations of light-enhanced intensification ratios and values at different temperatures, a simple model of possible light-enhanced reaction mechanism was proposed, with which the contribution of light to the DRM reaction was deeply discussed. Meanwhile, combined with in situ DRIFTS characterization, the effects of operating conditions on specific micro-steps of the reaction were determined carefully. The obtained conclusions are of great practical significance for the design, development and process parameter optimization of photo-thermal DRM reaction process.
The present quality control method of Chinese medicinal materials (CMM) has obvious deficiency, which cannot be compatible with the multi-target and multi-component characteristics and production process of CMM. Plant metabolomics with a huge impetus to comprehensively characterize the metabolites and clarify the complexity and integrity of CMM, has been widely used in the research of CMM. This article comprehensively reviewed the application of plant metabolomics in the quality control of CMM. It introduced the concept, technique, and application examples, discussed the prospects, limitations, improvements of plant metabolomics. MS and NMR, as important techniques for plant metabolomics, are mainly highlighted in the case references. The purpose of this article is to clarify the advantage of plants metabolomics for promoting the optimization of the CMM quality control system and proposing a system approach to realize the overall quality control of CMM based on plant metabolomics combined with multidisciplinary method.
Abstract Background: Grazing and house feeding methods have been studied on yak, but there is no relevant research on grazing and indoor feeding of Jersey cattle on the Qinghai-Tibet Plateau. Results: In this study, the differences in metabolites in the serum and rumen of Tibet Plateau Jersey cattle in total mixed ration house feeding and grazing supplementary feeding were assessed. The rumen fermentation parameters, bacterial community, serum antioxidant indices, immune indices and metabolites of total mixed rations house-feeding Jersey cattle (Group B, n =6) and grazing supplementary-feeding Jersey cattle (Group G, n =6) were evaluated. The rumen fermentation parameters results showed that the acetic acid and propionic acid concentrations and the ammonia nitrogen concentration in Group B were significantly higher than those in Group G (P < 0.05). The rumen bacterial community 16S rDNA gene results showed that The Chao1 index was significantly higher in Group G than in Group B (P < 0.05), and the observed_species, Shannon and Simpson indices were not significantly different between the two groups (P > 0.05). The distance between the two groups by principal component analysis was not significant, and adnoism analysis showed that there was no significant difference in rumen flora between Group G and Group B (R=0.55, P=0.08). Antioxidant and immune indices analysis of serum results showed that there was no significant difference in total antioxidant capacity between Group G and Group B (P > 0.05), while IL-6, Ig-M and TNF-α were significantly higher in Group G than in Group B (P < 0.05). LC‒MS metabolomics analysis of serum results showed that, A total of 149 major serum differential metabolites were identified between Group G and Group B. The differential metabolites were mainly enriched in the metabolic pathways of biosynthesis of amino acids, protein digestion and absorption, ABC transporters, aminoacyl-tRNA biosynthesis, mineral absorption and biosynthesis of unsaturated fatty acids and other metabolic pathways. Conclusions : The results of this study revealed the differences in rumen fermentation and serum metabolism of Jersey cattle under different feeding methods, providing a theoretical basis for the scientific feeding of Tibetan Plateau Jersey cattle.
