Objective To explore the adequacy of maintenance hemodialysis by using the Healthcare Failure Modes and Effects Analysis (HFMEA) method, so as to improve the dialysis quality and prognosis of hemodialysis patients. Methods A total of 78 patients who underwent maintenance hemodialysis in Zhongshan Hospital Fudan University (Xiamen Branch) from January 2021 to December 2021 were enrolled. The adequacy of hemodialysis was measured by using single-pool urea clearance (spKt/V). Patients were divided into the standard group (spKt/V≥1. 2) and the non-standard group (spKt/V

Objective To investigate the psychological stress and experience of elderly patients under the COVID-19 epidemic, and to provide reference for establishment of targeted interventions. Methods The phenomenological methodology was used in the study. An Semi-structure interview was conducted with 8 elderly patients with COVID-19, and the theme was extracted by Colaizzi’s 7-step analysis method. Results Four themes were extracted: emotional reaction of elderly patients after COVID-19 diagnosis, cognitive reaction of elderly patients after COVID-19 diagnosis, behavior reaction of elderly patients after COVID-19 diagnosis, and physiological reaction elderly patients after COVID-19 diagnosis. Conclusion There were multiple needs among elderly patients under the COVID-19 epidemic, and their reaction to psychological stress should be taken into consideration. Well-designed and individualized health education and psychological support should be provided by online and offline services, in order to relieve the anxiety level and enhance the confidence of elderly patients.

The Scotia Sea is the most densely distributed area of Antarctic krill (Euphausia superba) resources, and is also the traditional fishing ground for krill fishery, but population structure of krill is complex and varies widely in this region. It plays the key role of females in the population for stabling structure and maintaining size of population. In order to understand the population dynamics of krill in this region, the temporal and spatial variability in female stock of krill resource in this region was analyzed using samples randomly collected by fishery surveys from January to September, 2016 to 2022. The results showed that there were significant differences in the development stages of krill annually. During 2016-2022, female krill stock was mainly dominated by subadults, followed by adults, and the proportion of juveniles was low. For the perspective of the annual variation of sexual maturity, the proportions of subadults (stages 2FC and 2FD) were generally higher than that of stage 2FB individuals. In terms of seasons, the female stock structure was relatively simple in winter and spring, while that was very complex in summer and autumn, the subadults was predominant in the stock. In addition, the structure of female krill stock was different between regions, the proportion of adults in the South Orkney Islands was the highest (65. 4%), while the subadults was predominant in the stock (89. 9%) and no juveniles occurred at South Georgia.

Atherosclerosis (As) is the pathological basis of various vascular diseases, which affects the function of important organs. Recent studies have found that N 6 -methyladenosine (m6 A) modification plays a vital role in As. This paper summarizes the regulatory effects of m6 A modification on vascular endothelial cell (VEC) injury, vascular smooth muscle cell (VSMC) transformation, macrophage (Mø) differentiation, foam cell (FC) formation, pyroptosis, and lipid regulation, and summarizes the regulation function of some m6 A regulatory proteins in As.

Atomic structure, a fundamental topic and teaching difficulty in inorganic chemistry, poses significant challenges for educators. Overcoming these obstacles has remained a constant concern for teachers, necessitating urgent solutions. In this study, we explore the teaching process of atomic structure by employing a meticulously crafted classroom approach, centered around the principles of quantum mechanics, and interweaving the entire curriculum. Emphasizing the importance of active student engagement, we encourage thorough preparation, leverage problemoriented teaching methods, and harness the power of multimedia tools to transform dry and monotonous content into vivid and captivating lessons. By instilling an appreciation for the historical context and development of atomic structure, we aim to nurture students' scientific spirit and foster their innovative abilities. Ultimately, our approach strives to enhance students' learning, comprehension, and mastery of the subject matter, resulting in improved classroom teaching quality and heightened learning efficiency of students.

The concrete inside the embedded rock-socketed steel pipe pile is prefabricated on land. After embedding the steel pipe piles, grouting for pile's sidewalls is carried out, and the grout material generates buoyancy on pile, leading to a risk of floating during the grouting process. Existing preventive measures are high in risk and low in efficiency. To address the issue of grout-induced floating in embedded rock-socketed steel pipe piles, a solution is proposed. It involves analyzing the forces during the grouting process, adding a certain amount of quick-setting agent to the grout material, optimizing the layout of the prefabricated grout pipeline, altering the grouting construction process, and rigorously controlling the construction procedures. This approach enables continuous one-time grouting for the segments along the rock wall and steel casing of the embedded rock-socketed steel pipe piles. Through on-site comparisons and verification of grouting process, as well as engineering applications, this method effectively resolves the problem of floating during grouting for embedded rock-socketed steel pipe piles. It ensures construction quality and enhances construction efficiency. [ABSTRACT FROM AUTHOR]

Single-atom catalysts (SACs) have attracted much attention due to their unique structure and properties, especially in terms of maximizing the utilization of atoms and improving the intrinsic catalytic activity. In recent years, SAC-based advanced oxidation processes (AOPs) have become a new field in the environmental field, and have been widely used in the removal of various refractory organic pollutants. In this paper, the synthesis and characterization methods of SACs are analyzed, and the catalytic performance of SACs in different Fenton-like catalytic reactions is emphasized. In addition, tests of the continuous flow of SACs fixed on membrane or columnar filters are presented to explore the potential of SACs for practical applications in Fenton-like reactions. Finally, we prospect the future rational SACs design and the exploration direction of the Fenton-like reaction mechanism, aiming to improve the application potential of Fenton-like reaction in practical wastewater.

Different membership degrees in the probabilistic hesitant fuzzy element entrust decisionmaking experts with comprehensive weights, thereby constructing a probabilistic hesitant fuzzy set with more information and more in line with the needs of decision problems - weighted probabilistic hesitant fuzzy set （WPHFS）, which is described by three-dimensional vector. On this basis, the threedimensional vector score function model, three-dimensional vector deviation function model of weighted probabilistic hesitant fuzzy element（WPHFE）and two weighted probabilistic hesitant fuzzy element size criteria are established. Firstly, weighted probabilistic hesitant fuzzy element's threedimensional vector score function value and three-dimensional vector deviation function value are used to calculate the external weight and internal weight of attributes respectively, and then to calculate the comprehensive weight of attributes. Secondly, based on the idea of maximum deviation, a method for calculating the comprehensive weight of decision experts is presented with the combination with the comprehensive weight of decision experts and the comprehensive weight of attributes. Again, the 0-1 priority relationship matrix is used to intuitively obtain the total attribute weight advantage value and total attribute weight disadvantage value of two alternatives. The goal of sorting scheme is achieved according to the size between the two. Finally, the practical value of the theory and method are finally illustrated by an application example.
