Rock pulverization is recommended when converting boreal forests to agricultural land use to facilitate tillage operations. Resulting rock dust incorporation might alter physical, chemical, and biological properties of soils. We assessed soil nematode trophic group abundances and indices, basal and burst respiration, and phosphorus extractability after land use conversion (LUC) and recent pulverization (<1 year) on three soil types in eastern Newfoundland, Canada. Nine treatments representing varied pulverization statuses (managed pulverized, managed unpulverized, natural) were nested in soil type (Podzol, Luvisol, and Organic). Conversion to agriculture impacted soil quality more than the recent rock pulverization. Nonetheless, nematode indices (fungivore/bacterivore, fungivore/fungivore+bacterivore, fungivore + bacterivore/herbivore) suggested no significant functional differences with either LUC or pulverization. Soil organic matter (SOM) and pH were substantial direct and indirect drivers of nematode community composition and soil respiration, mainly by altering availability of aluminium and iron. The functional parameters diverged between Organic and mineral soils. For all soils, most respiration parameters were significantly related to SOM, pH, available iron and aluminium. For nematodes, significant relationships were identified in the Organic soil: bacterivores and fungivores abundances were inversely related to SOM, and bacterivore abundance was positively related to pH. While for the mineral soils, citric acid extracted more phosphorus than the Mehlich-3 or water methods, Mehlich-3 was most effective for the Organic soil. Pulverization did not affect phosphorus extractability. The distinct relationships between soil quality properties and functional parameters between mineral and Organic soils are of interest for further investigations into the concepts of soil quality and soil health.

Authors: Zhang Ruijun , Zhang Hao , Yang Zhe
Published: July 2022

To reduce the aerodynamic load of super high-speed elevators, in this paper, the coefficient of drag [Formula: see text] and the coefficient of yawing moment [Formula: see text] of the elevator are selected as optimization objectives for the optimization of the air rectification cover (ARC) shape. The elliptic curve method was used to build the parametric model of the ARCs, six design variables were selected, and the design space of the ARC was determined. With the optimal Latin hypercube design method, the training points were selected, and the computational fluid dynamics numerical simulation was conducted to calculate the corresponding responses. Then, the relationship between the design variables and the responses was analyzed. The radial basis function (RBF) surrogate model of the relationship between the design variables and responses was constructed. Finally, the non-dominated sorting genetic algorithm-II (NSGA-II) was employed to optimize the shape of the ARC. The results show that the [Formula: see text] and [Formula: see text] decrease by 16.51% and 60.92%, respectively, compared with the unoptimized ARC, indicating that the ARC designed in this paper is optimized and can effectively reduce the aerodynamic load. Furthermore, among all the design variables, the bluntness of the ARC in the [Formula: see text]-direction has the most significant effect on the aerodynamic load, and the height of the ARC ([Formula: see text] and [Formula: see text]) has the second most significant effect on the aerodynamic load of elevators.
Effective Inertia Coefficients Prediction and Cell Size Effects in Thickness Direction of Periodic Composite Plates
Authors: Huang Zhiwei , Xing Yufeng , Gao Yahe
Published: July 2022

This paper develops a new homogenization method for free vibration problems of periodic composite plates. In this new method, three-dimensional (3D) periodic plates are equivalent to Reissner–Mindlin plates with both effective stiffnesses and effective inertia coefficients. The effective stiffnesses for the dynamic problems are the same as those for the static problems, and they can be achieved by the equivalence principle of macro- and microscopic internal virtual work. To fully take the inertia effects into account, the effective inertia coefficients including the effective translational, translational–rotational and rotational inertias are determined by the two-scale equivalence principle of kinetic energies under three rigid modes. In addition, cell size effects in the thickness direction of composite plates are investigated by using the proposed method and the asymptotic homogenization method (AHM). Numerical experiments validate the effectiveness of the proposed equivalent method for different scale factors, and show that the rotational inertia cannot be ignored for out-of-plane deformations, especially for higher-order modes. Besides, numerical comparisons show that the cell size effects are not negligible when using the AHM to analyze the out-of-plane deformations, and three or more repeated unit cells in the thickness direction are required to ensure accuracy.
Vibration Reduction Mechanism of a Novel Enhanced Particle Inerter Device
Authors: Lu Zheng , Zhou Chaojie , Rong Kunjie , Zhang Jiawei , Du Jiang
Published: July 2022

This work proposes an enhanced particle inerter device (EPID) capable of significantly enhancing the vibration control effect (VCE) of a conventional particle tuned mass damper (PTMD). EPID, an inerter is coupled to the PTMD device, that is, the inerter is attached to the damper cavity on one end and to the ground on the other, mainly using its mass amplification effect. To accomplish the goal, the EPID’s mechanical model is established first. Then, the system’s governing equation is derived based on the single degree of freedom (SDOF) system, and the EPID’s effectiveness is verified via inputting seismic excitation. Finally, the parameter analysis and multi-objective optimization design are carried out for EPID, and the superiority of the proposed multi-objective optimization design method compared with the traditional design method is verified. The results indicate that EPID can effectively minimize the main structure’s displacement and acceleration response. In particular, under the El Centro wave’s excitation, the vibration reduction rate of the dynamic responses (peak response and root mean square response) is close to 50%, which is over 35% increasing compared to PTMD, and its VCE is better for excitation band changes. At the same time, it is found that the lower the damper’s auxiliary mass ratio, the more obvious the enhancement of the inerter system’s VCE is, which brings about the lightweight design of the high-control effect of PTMD.

The structural formation, morphological and chemical composition of as-prepared MnO2 cube/r-GO nanocomposite were characterized by powder X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The FE-SEM and TEM images were revealed that the MnO2 cubes are homogeneously distributed on the surface of r-GO nanosheets. The electrochemical results showed that the high specific capacitance of MnO2 cube/r-GO nanocomposite was 1570 F g−1 at a current density of 2 A g−1 in 1 M Na2SO4 electrolyte solution. The long life-term cycling performance of MnO2 cube/r-GO nanocomposite were delivered at outstanding capacitance retention of 99.3% subsequently 10,000 charge-discharge cycles at 8 A g−1. Moreover, we construct the asymmetric supercapacitor (ASC) of MnO2/r-GO//r-GO for practical application. Herein, MnO2/r-GO act as an anode material and r-GO as a cathode material.

Published: July 2022

Exploring the improvement of classroom teaching effect under the background of sports education integration in China has important practical significance and theoretical value. Integration of yard sports education and classroom course education in the school is a novel concept put forward by China’s sports and education circles to deepen the combination of sports and education. Although it is only a word different from the combination of sports and education to integrating sports and course education in the school, it is a groundbreaking theoretical and practical innovation for China in terms of changing the competitive sports development model and cultivating exceptional athletes. It is a new way to promote the sustainable development of sports and education according to the scientific outlook on development. Its fundamental significance is to change the closed state of sports and education departments, put sports and education in the background of economic and social development in a certain region, and fundamentally reform the content and mode of education. Therefore, this paper proposes a comprehensive rating model of classroom teaching effects based on deep learning (DL) and machine learning (ML) techniques. In this paper, the Jaffe expression dataset is used to train and test the utilized ML and DL models such as ResNet50, random forest (RF), logistic regression (LR), K‐nearest neighbor (k‐NN), and decision tree (DT). Further, with the help of artificial intelligence (AI) techniques, the algorithms can objectively evaluate the classroom teaching effect after the integration of physical education with classroom education and provide important guidance for the modernization and intellectualization of China’s educational methods in the future.

Published: July 2022

In recent years, the visual analysis of human motion has become a frontier direction in the field of computer vision. It recognizes, identifies, and tracks people in image sequences, as well as understands and describes their actions. Using computer vision technology to study the field of image processing and pattern recognition, as well as extracting and effectively identifying human motion features from video images, has become a hot topic of concern with the rapid development and popularization of information technology. This study presents a method for analyzing the characteristics of moving human bodies based on image recognition, introduces the extraction function method, and analyzes the characteristics of the extraction function to improve the ability to analyze the characteristics of moving human bodies. To achieve fine segmentation, the hierarchical clustering algorithm is used to segment the periodic motion in each motion. Different benchmark databases and self-built data were used in the experiments. Experiments show that the algorithm can achieve good classification and recognition results while maintaining low computational complexity and extracting less feature data. It can also organically integrate the static and dynamic features of human walking.

Energy waste altogether adds to expanded expenses in the car fabricating industry, which is liable to energy use limitations and tax assessment from national and global strategy creators and confinements and charges from national energy suppliers. This checking is essential for energy sparing since it empowers organizations to roll out operational improvements to diminish energy utilization and expenses. The primary test to energy observation is the need to incorporate assembling and energy checking and control gadgets that help diverse correspondence conventions and are generally dispersed over a wide region. One of the most significant challenges in the advancement of the Internet of Things (IoT) has been the powering of billions of connected devices. Evaluation of digital services considering an energy impression of the Internet normally requires models of the energy intensity of the Internet. A typical way to deal with the display of the energy intensity is to consolidate assessments of market studies of introduced gadgets on a national or worldwide scale and their related power utilization with the aggregate information volume transported at a similar scale. Energy sources are a fundamental part of society development, and a steady power supply is essential for today’s progress. End-use energy is transferred to various consumers via power transmission and circulation networks after being transformed to optional energy as electricity by various power facilities. The power grid serves as the physical stage for both wide-area electric power sharing and display exchanges, and it is at the heart of auxiliary energy sources. In this manner, it attempts to connect the part of a center point between essential energy and end-use energy. With the bidirectional power stream given by the Energy Internet, different techniques are elevated to enhance and increase the energy usage between Energy Internet and Main-Grid. Energy proficiency and, in addition, quick information transmission are fundamental to green correspondences-based applications for IoT. Here, we are trying to provide a state-of-the-art survey over various Internet of Energy techniques along with IoT.
Organizational Justice and Health: Reviewing Two Decades of Studies
Authors: Cachón-Alonso Laura , Elovainio Marko
Published: July 2022

Organizational justice refers to employees’ perceptions of the fairness of decision-making rules and policies in the workplace. Lack of justice is suggested to be a significant psychosocial risk factor that affects employees’ attitudes and health. The aim of this narrative review was to compile the evidence available about the effects of organizational justice on health. To this end, a literature search was carried out using the Web of Science, PubMed, and PsycINFO databases. The final sample consisted of 103 articles that studied the effects of justice on mental health (40 results), job stress (26), sickness absence (15), physical health (14), absenteeism/presenteeism (3), safety at work (3), and health of third parties (2). The results show that perceptions of workplace justice predict employees’ mental health, stress-related health problems, and lower levels of sickness absence were relatively compelling. Future studies should focus on less-researched outcomes and on how these associations are modified by other variables for a better understanding of how justice affects health, with a view to being able to carry out preventive measures more efficiently.
Time-Domain Characteristics of Residential Parking and SEM-BL Integration Model of Parking Method Choice Behaviour
Authors: Chao Zeng , Zihao Cui , Hao Qiao
Published: July 2022

Correct understanding of the residential parking characteristics and parking behavioral regularities is important to the planning of parking facilities, the selection of parking equipment, and the formulation of parking management measures in residential areas. There are few in-depth reports on the time domain characteristics of the residential parking and the parking choice behavior of developers and drivers. Besides, the influence of developers’ potential demands and drivers’ mental latent variables on the results of parking choice has been ignored. To address the gap, in this paper, we propose the concept of latent variables for parking choice based on the analysis of the time domain characteristics of residential parking in different cities and areas. We construct the SEM-BL integrated model for developers and drivers that considers the combined effect of both manifest and latent variables for the actual residential situation and analyze the factors influencing the choice of stereoscopic parking facilities from the perspective of developers and drivers in residential areas. The results show that the type of residential area, floor space, and plot ratio have a critical impact on parking choice. Residential drivers are most concerned about factors such as walking distance after parking, access convenience, pick-up time, pedestrian access, and environment, while developers choose a stereoscopic parking garage with more concern for economy, ignoring the consideration of drivers for walking distance after parking and convenience of accessing the car. Therefore, the mismatch between the needs of both sides is one of the important factors that make it difficult to solve the problem of parking in residential areas. Based on these results, we put forward a proposal for residential parking planning and equipment selection that takes into account the common needs of both developers and drivers.

Darier disease (DD) is a rare genodermatoses characterized by greasy hyperkeratotic papules in seborrheic regions and nail and oral changes. Histologically, it presents as suprabasal clefts with acantholytic and dyskeratotic cells. Acrokertasosis verruciformis of Hopf (AKVH) is considered an allelic variant with clinical overlap where Church spires are seen histologically without dyskeratoses. Patients are susceptible to various viral and bacterial skin infections requiring prevention and treatment of infection. Nonspecific treatment includes patient counseling on exacerbating factors. Although there are no curative treatments for DD, topical corticosteroids and systemic retinoids may be used to control inflammation and hyperkeratosis. We are reporting a rare case with clinical and histological findings of DD with AKVH in a 17-year-old boy with keratotic papules, presented on the hands and feet, nose, and ears without mucosal involvement.

Published: July 2022

Background. Financial crises become more probable and severe when debt levels exceed specific thresholds. This finding strongly indicates that debt can become excessive in some circumstances. All the above are from previous studies that mentioned the statistics of debts, financial crises, and defaults in countries without mentioning the reasons that led to the debts. Objective. The aim of this study is to identify the causes that led to the accumulation of debts by individuals. Methods and Materials. A cross-sectional survey was administered to the common populace in KSA, utilizing Google shapes to gather information. The target group comprised 143 males (34.5%) and 272 females (65.5%) responders. Statistical analysis methods were based on factor analysis and regression analysis of fractional factorials. Results. The results of the analysis were summarized by the factors for the first stage: the reasons that led to the debt crisis for individuals were S1, S2, and S5–S13. The results of the second method, regression analysis, show that the reasons that led to the debt crisis for individuals are S4 and S11. Conclusion. Referring to the results of the analysis of the two methods, it was found that there is a common factor between them, S11, and thus, S11 (poor management and inefficiency) becomes the actual cause that led to the debt crisis for individuals.

Authors: Fu Qijun
Published: July 2022

This paper studies and analyzes three aspects: DL model, English talent training, and quality evaluation analysis, so as to get more rigorous and accurate quality evaluation results, and make relevant plans for future research directions. This paper focuses on model and method analysis to carry out experiments and analysis on three aspects: DL, personnel training, and quality evaluation. The experiment and inquiry of deep learning are divided into correct rate and loss. In 0-70 epoch, the highest training correct rate is 0.975, and with the increase of training times, the training correct rate is also increasing. According to the statistical investigation, 42.91% of English teachers are satisfied with their academic level, 38.48% with their oral English level, 38.89% with their teaching quality, 41.02% with their teaching methods, 40.29% with their teaching spirit, and 39.88% with their knowledge structure. At the same time, according to the statistics of students, graduates and teachers’ problems in English talent training, the largest proportion is the poor level of teaching resources, so we should improve the efficiency from the level of teaching resources. In order to improve the efficiency of quality evaluation method, this paper combines AF algorithm and BQ algorithm under deep learning. The error rate of algebraic algorithm is compared. Through six groups of sample data, it can be seen that the highest error rate of AF algorithm is 5.86% and the lowest is 0.92%, the highest error rate of BQ algorithm is 10.70% and the lowest is 1.10%, and the highest error rate of algebraic algorithm is 10.70% and the lowest error rate is 5%. In contrast, the error rate of AF algorithm is lower and more stable. Next, this paper compares and analyzes the performance of the AF algorithm, BQ algorithm, and algebraic algorithm. According to the experimental results, it can be seen that the AF algorithm is more accurate than the BQ algorithm and algebraic algorithm in accuracy, recall rate,

Trimethylamine N-Oxide Promotes Cell Proliferation and Angiogenesis in Colorectal Cancer
Authors: Yang Shuyan , Dai Hui , Lu Yimei , Li Rui , Gao Chengjin , Pan Shuming
Published: July 2022

Background. Of all intestinal microbiome-derived metabolites, trimethylamine N-oxide (TMAO) has received increasing attention because of its potent role in colorectal cancer development. Accumulating evidence suggests that TMAO generated by the gut microbiota is a new and important player in the etiological process of colorectal cancer. Nevertheless, the carcinogenic mechanism of TMAO in colorectal cancer remains unclear. In this study, TMAO induced colorectal cancer cell proliferation and produced higher vascular endothelial growth factor A (VEGFA) levels in vitro. In vivo, after long-term choline feeding in tumor-bearing mice, circulating TMAO levels, tumor volume, new blood vessel formation, and VEGFA and CD31 amounts were increased significantly. This study revealed that TMAO exerts oncogenic effects by promoting cell proliferation and angiogenesis in colorectal cancer.

Published: July 2022

Aim. Traditional sedation management consists of doctors adjusting the dosage of sedative drugs or adding other drugs in combination according to the evaluation of nurses; the nurses then execute the orders. The nurses’ passive execution in the process is not the ideal model for continuous evaluation and observation of sedation. This study aims to investigate the application and effects of nurse-provided procedural sedation and analgesia for patients in intensive care unit. Methods. The experimental group consisted of 354 heart surgery patients who received procedural sedation and analgesia from nurses from November 2020 to August 2021. The control group consisted of 301 patients who had had heart surgery and received the traditional sedation management program from January to October 2020. The differences in levels of the sedative effect, delirium, and unplanned extubation of patients between these two groups were compared. Results. There were no significant differences in baseline characteristics between the two groups (

P
>
0.05

). It was found that both insufficient sedation and excessive sedation decreased in the experimental group when compared to the control group, while the appropriate proportion of sedation increased (72.41% versus 37.98%); the difference was statistically significant (

P
<
0.05

). The incidence of delirium was lower for patients in the experimental group than for patients in the control group (37.01% versus 66.45%); the difference was statistically significant (

P
<
0.05

). The incidence of unplanned extubation caused by patient factors was lower for the experimental group than for the control group, but the difference was not statistically significant (

P
>
0.05

). Conclusion. The programmed sedation scheme led by nurses can improve the sedation effect and reduce the incidence of delirium. Implications for Practice. The management team gives the sedative goal and establishes the standard flowchart. The sedation management led by the nurse according to the goal and flowchart is better than the traditional sedation management.

Published: July 2022

It was an important step to understand the evolution of urban forms by clarifying the development process of spatial forms over time. In this step, the application of historical maps with rich spatial and temporal information provided an opportunity to increase the objectivity, accuracy, and repeatability of the research. On the other hand, efficient extraction of spatiotemporal information from historical maps as a basis for subsequent analysis remained a common bottleneck in the current time. What could be done to effectively extract urban spatial elements from historical maps? How could spatial elements be translated to obtain quantified data that could be used for spatiotemporal analysis? In this study, we selected historical maps and archival illustrations of the former British Concession area of Tianjin, China, as research materials to explore the extraction and digital translation methods of urban spatial elements for analyzing the evolution of urban spatial form based on historical maps. This method consisted of loading the map, selecting the registration and calibration point, correcting residual, and saving the path of calibration. The study discussed the specific operation of these steps. In addition, based on this method, this paper analyzed the road network, water area, bridges, and gardens in the former British Concession area of Tianjin, China, to verify the feasibility and accuracy of this method. This method was expected to advance the study of urban spatial morphological evolution and its mechanism with rich data of historical maps.
How to Maintain a Sustainable Doctor-Patient Relationship in Healthcare in China: A Structural Equation Modeling Approach
Authors: Wang Zhan-You , Zhang Xin , Ma Liang
Published: July 2022

It is important to identify means of improving and maintaining a sustainable doctor-patient relationship to address current healthcare issues. Although many studies have made outstanding contributions to the healthcare doctor-patient relationship literature, little work has been done to explore the influencing elements of the doctor-patient relationship in relation to expectation confirmation theory. To fill this gap, this study produced a theoretical framework model of the influencing factors of the doctor-patient relationship according to the expectation confirmation theory. Data from 335 Chinese patients were analyzed using a structural equation modeling method, and the results showed that patient satisfaction and patient trust are the most important factors in building a good relationship between doctor and patient. Furthermore, three components of postdiagnosis patient’s perception, namely, perceived service quality, perceived communication quality, and perceived service attitude, are examined. These have a significant impact on patient confirmation. These three components ultimately affect the doctor-patient relationship. This study will be helpful for doctors to understand patients’ service demands and their future diagnosis behavior. The proposals of this study may lead to optimization of the process of diagnosis and improvements in the quality of clinic services.

Objectives. This study was designed to explore the relationship between Helicobacter pylori (Hp) infection and reflux laryngopharyngitis (RLP) and to evaluate the outcome of anti-Hp therapy in improving RLP symptoms. Methods. A total of 410 patients with RLP were enrolled and tested for Hp infection. The association of Hp infection with reflux symptom index (RSI) and reflux finding score (RFS) was determined. Hp-positive patients received either a proton pump inhibitor (PPI) omeprazole alone (control group) or a combination regimen (experimental group) consisting of omeprazole, mosapride citrate, amoxicillin, and clarithromycin. Therapeutic outcomes were compared 4 weeks later. Results. Of the 410 participants, 290 were Hp-positive and 120 Hp-negative. Both RSI and RFS were significantly higher in Hp-positive patients than in Hp-negative patients. Hp infection status was positively correlated with RSI (

P
<
0.05

) and RFS (

P
<
0.05

). The overall response rate was higher in the experimental group than in the control group. Both the groups had a significant reduction in RSI and RFS after therapy, with a greater improvement in the experimental group (

P
<
0.05

). Conclusion. Our findings establish a link between Hp infection and RLP. Anti-Hp therapy improves RSI and RFS in RLP patients. Therefore, Hp eradication drugs may be added to the PPI-based regimen in the treatment of RLP.

Griseofulvin (GF) is a hydrophobic drug with a low solubility. In order to improve the solubility of GF, which has low water solubility, this report uses the spray-drying technique to prepare complexes with lactose to promote the solubility and oral bioavailability of GF. The solution samples were spray dried using different ratios of ethanol or acetone solutions as dissolution media. By characterization of the obtained spray-dried powders, we found that the solubility of the different groups of samples obtained by spray drying was increased, and similarly, their dissolution rates were also increased to different degrees. By comparison, the greatest increase in solubility was obtained in an aqueous acetone solution, showing the greatest ability and efficiency of acetone in promoting the solubility of GF during the spray-drying process.
Construction of Bilingual Teaching Mode Based on Digital Twinning Technology

Published: July 2022

Based on the digital twin technology, a digital twin platform can be built to connect the real teaching space with the virtual teaching space and become the mainstream of online teaching space. All this has determined that the social demand for designers’ education is undergoing fundamental changes. The so-called “scientific and technological progress, education first” bilingual education is undergoing comprehensive and profound changes in the digital age, which has a strong impact on the traditional bilingual teaching mode and concept. Traditional concepts, aging theoretical knowledge, and backward teaching methods will inevitably be eliminated and updated gradually in the contest with digitalization, which makes it necessary to transform traditional bilingual education into digital bilingual education. Through the comparative experimental analysis of the teaching effect, the independent sample t-test shows that the t-statistic is 3.634, and the corresponding significance level is 0.013, which is less than 0.05. It shows that there are significant differences between boys and girls in bilingual teaching in this class of digital twin technology experimental teaching. However, compared with the control class, the results of both boys and girls are higher, so to some extent, it shows that the application of digital twin technology experimental teaching in bilingual teaching will indeed produce certain results.

The number and function of circulating endothelial progenitor cells (EPCs) decreased in stable coronary artery disease. Nevertheless, there were few studies that explored the variation of EPC and the relationship with the severity of coronary artery lesions in unstable angina (UA). Therefore, this leaves an area for the investigation of the difference in the number and activity of circulating EPCs and the relationship with the Gensini score in unstable angina. Fluorescence-activated cell sorter analysis, as well as DiI-acLDL and lectin fluorescent staining measure the number of circulating EPCs. The transwell chamber assay and MTT were evaluated by the migration and proliferation of circulating EPCs. In addition, the flow-mediated dilation (FMD), Gensini score, and IL-6 levels in plasma were determined. We found that UA patients had the higher number and lower function of circulating EPCs. With the increase in severity of coronary artery lesions, the migration and proliferation of EPCs were decreased. Moreover, the function of the circulating EPCs was negatively associated with severity of coronary artery lesions in unstable angina. In addition, UA patients presented elevated IL-6, which was negatively correlated with the function of circulating EPCs and FMD and positively correlated with the severity of coronary artery lesions evaluated by the Gensini score. These findings revealed the decline in the function of circulating EPCs was associated with the severity of coronary artery disease, which may be related to systemic inflammation.

Purpose. To explore the nursing research of prostatic hyperplasia based on continuous nursing and based on the combination of medical care and nursing.Methods. A prospective study of 96 patients with benign prostatic hyperplasia admitted to our hospital from November 2019 to May 2021 was selected. According to the random number table method, they were divided into an observation group and a control group with 48 cases each. The control group used routine nursing and discharge guidance, and the observation group implemented continuous care based on the combination of medical care and nursing on the basis of the control group. The differences in the scores of quality of life, self-care ability, quality of life score, and sleep quality were compared between the two groups. Results. After 3 months of nursing, the quality of life scores (health status, psychology, social relationship, environment, physiology, and quality of life scores) of the observation group was higher than those of the control group (

P
<
0.05

). After 3 months of nursing, the quality of life scores of disease, physiology, society, psychology, and satisfaction of the observation group was significantly higher than those of the control group, which was statistically significant (

P
<
0.05

). After 3 months of nursing, the observation group’s sleep quality scores in all dimensions (time to fall asleep, sleep time, sleep quality, sleep efficiency, hypnotics, sleep disorders, and day disorders) were higher than those of the control group (

P
<
0.05

). After 3 months of nursing, the observation group’s self-care skill score, self-responsibility score, health knowledge score, and self-concept score were better than those of the control group (

P
<
0.05

). Conclusion. Continued nursing care based on the combination of medical and health care for prostate hyperplasia is beneficial to improve sleep quality and improve the patient’s quality of life score and self-care ability and provide certain references for clinical care of patients with benign prostatic hyperplasia.

Studies have shown that oral microbiota dysbiosis affects patients’ lung function, promoting the development and acute exacerbation of chronic obstructive pulmonary disease (COPD). In this paper, we review the mechanisms potentially linking COPD with periodontitis. Oral microbiota enters the respiratory system through clinical microaspiration to aggravate lung microbiota dysbiosis and induce lung injury by entering the respiratory tract directly. Appropriate interventions for dysbiosis such as periodontal therapy or oral microbial transplantation may prevent the progression of COPD.
