Authors: Zhao Yanhong , Wang Chenmei , Dai Hong
Published: September 2022

Objective. The current study aimed to explore the effects of rapid rehabilitation nursing based on the syndrome differentiation and treatment theory of Traditional Chinese medicine (TCM) on the sleep and life quality of patients undergoing multi-endoscope gallbladder-preserving cholecystolithotomy (MEGPCL). Methods. 112 patients who underwent MEGPCL were chosen as subjects for this study. These 112 subjects were randomly divided into observational and control groups, with 56 cases in each group. The control group was treated with conventional western medicine rapid rehabilitation nursing intervention, and the observation group was treated with TCM treatment theory of syndrome differentiation rapid rehabilitation nursing intervention. The recovery rates of gastrointestinal function of the two groups werecompared and evaluated. The psychological resilience, pain degree, treatment compliance, self-care ability, sleep quality, and patient’s life quality prior to and following the interventive therapy were determined by the CD-RISC, SF-MPQ, Kolcaba score, BMQ, ESCA, PSQI, and GLQI, respectively. The prevalence of postoperative complications such as different infections and lower limb venous thrombosis during hospitalization were statistically analyzed in the two designed groups. Results. It was revealed that in the observation group, the time span for anus exhaust and anus defecation, bowel sound recovery, feeding, and hospital stay was less than in the control group (all

P
<
0.05

). After the intervention, Kolcaba and CD-RISC scores were higher in the observation group as compared to control group, while SF-MPQ scores were less than the control group (all

P
<
0.05

). BMQ, ESCA, and GLQI scores were also higher in the observation group, and PSQI score was less than the control group (all

P
<
0.05

). It was also observed that the incidence of postoperative complications was lower in the observation group (all

P
<
0.05

). Conclusion. The application of TCM syndrome differentiation theory in the rehabilitation nursing of patients undergoing MEGPCL can improve treatment compliance, relieve postoperative pain, promote postoperative gastrointestinal function recovery, restores sleep quality, and improve patients’ life quality.

Authors: Zuo Leibin , Li Qinfeng , Ma Cunming , Yadong Li , Hu Chuanchuan
Published: September 2022

A long-span natural gas pipeline suspension bridge is prone to buffeting under the action of a turbulent wind field. In order to accurately calculate the buffeting response of the structure under a turbulent wind field, the 1 : 15 segment model wind tunnel test is used to obtain the aerodynamic coefficient and flutter derivative of the bridge deck structure. According to the test results, the buffeting force coherence functions under five different span-directional spacing are fitted. The results show that the buffeting force coherence function corresponding to different wind attack angles has a peak at the corresponding wing grid vibration frequency in the low-frequency region; when the spacing increases to

r
=
0.51
 
m

or above, the amplitude of coherence function decreases significantly; for the spacing of

r
=
0.17
 
m

, the buffeting force coherence functions in different directions are obviously different but the corresponding coherence functions of resistance, lift, and torque show a similar curve trend between different wind attack angles. Based on the Scanlan buffeting force correction model, the buffeting response under the reference wind speed of 30.1 m/s is analyzed in the frequency domain and compared with the wind tunnel test results of the whole bridge. The results show that the buffeting response calculated in this paper is in good agreement with the wind tunnel test results of the whole bridge and the buffeting response law is consistent. The maximum value of vertical buffeting response is located near the 1/4 span, and the maximum values of lateral and torsional response are located in the middle of the span. The lateral buffeting displacement response is significantly greater than the vertical buffeting displacement response. Under different wind attack angles, the vertical, lateral, and torsional buffeting displacement responses of the bridge deck structure increase nonlinearly with the increase of wind speed.

Published: September 2022

Ewing sarcoma is a rare poorly differentiated and highly malignant tumor primarily affecting the skeletal system. It most commonly presents during the first two decades of life and rarely might it be of extraskeletal origin. Majority of extraskeletal cases are reported in the paravertebral and lower limb, with very few cases reported in the cervical spine region. We report a case of extraskeletal Ewing sarcoma in a 42-year-old man who presented with a 1-year history of neck swelling associated with neck pain, diagnosed by computed tomography and magnetic resonance imaging scans, in conjunction with histological analysis. Very few cases of cervical EES presenting as dumbbell tumors have been documented in the literature especially in this age group.

Published: September 2022

The application of computer vision technology in the medical field provides more accurate technical support for oral disease detection. The research proposes the CT image denoising algorithm based on wavelet and bilateral filtering. Through the study of the imaging principle of CT image and the CT image acquisition scene, the CT image data is filtered by wavelet and bilateral filtering algorithm, and the algorithm is proposed from the peak signal-to-noise ratio, structural similarity, and the effective detection of three-dimensional image construction of the image. The test results show that the proposed algorithm has excellent performance in the aspects of peak signal-to-noise ratio, structural similarity, and error of mean square. When the proportions of Gaussian noise are 10%, 20%, 30%, 40%, and 50%, the MSE error values of the proposed algorithm are 0.002, 0.004, 0.006, and 0.007, respectively, and the performance is the best in the comparison of multiple algorithms. The contents of the research provide an important theoretical reference for the treatment of clinical oral diseases.

Published: September 2022

Dorsal cheilectomy is often used as a first-line surgical treatment for hallux rigidus; however, revision surgery is needed in nearly 9% of cases. One option for revision surgery is interpositional arthroplasty, which is designed to preserve joint motion and is favorable in young, active populations. This case discusses a young female patient with persistent, painful hallux rigidus and a large osteochondral defect despite prior dorsal cheilectomy. We performed an interpositional arthroplasty of the first metatarsophalangeal joint using an osteochondral allograft from the talus. At three-year follow-up, she had greatly improved function and was able to run without pain. To our knowledge, this is the first documented use of an osteochondral allograft from the talus in conjunction with metatarsophalangeal joint interpositional arthroplasty for treatment of hallux rigidus and a severe osteochondral defect. This technique introduces osseous subchondral scaffolding as well as mature hyaline cartilage into an osteochondral lesion, thereby reestablishing proper joint architecture and congruent articulation and ultimately improving range of motion and reducing pain. We present this technique as an experimental treatment option for restoring both the integrity and function of the metatarsophalangeal joint following trauma, osteochondritis dissecans, or prior operative failure in patients who wish to delay metatarsophalangeal joint fusion.

Published: September 2022

In this article, the effect of electromagnetic force with the chemical and thermal radiation effect on the Oldroyd-B fluid past an exponentially stretched sheet with a heat sink and porous medium was studied. The governing system of nonlinear partial differential equations has transformed into a system of ordinary differential equations using similarity transformations. The system is then solved numerically using a successive linearization method. The numerical results of velocity, temperature, and concentration profiles are represented graphically. Several parameters’ effects are investigated and examined. Local Nusselt number, skin friction coefficient, porosity, Deborah numbers, and local Sherwood number numerical values are listed and analyzed. The results reveal that many parameters have a significant impact on the fluid flow profiles. The concentration profiles were considerably affected by the reaction rate parameter, and the concentration thickness of the boundary layer decreased as the reaction rate parameter increased. The results of the analysis were compared to the results of existing works and found to be in excellent agreement.

Published: September 2022

Invasive fungal infection is a major threat to chronic granulomatous disease (CGD) patients. We present a rare case of invasive mycosis in a CGD boy. An 11-year-old preadolescent boy presented with fever, hypoxia, and dyspnea. Physical examination revealed left neck enlarged lymph nodes with healed scars. The chest revealed bilateral diminished air entry with bilateral coarse crackles. Peripheral blood leukocyte count was 28.260/μL with 84% neutrophil, 11% lymphocyte, and 4.4% monocyte. The patient’s condition deteriorated regardless of the empirical antibacterial against MRSA and suspected tuberculosis. A sputum sample was submitted for mycological investigation, and budding yeasts with pseudohyphae were detected in the direct smear and were isolated in pure culture using Sabouraud agar. Candida tropicalis was identified from cultural and microscopic features and confirmed by the Vitek 2 automated system. This result confirmed the invasive mycosis, obviously due to the underlying primary immunodeficiency, chronic granulomatous disease (CGD). Amphotericin was added, and he also received IV methylprednisolone for seven days. The patient improved and was weaned off oxygen with no fever. However, the patient was referred to a higher center for further workup, which confirmed CGD’s diagnosis. He is on the list for HLA-identical bone marrow transplantation (BMT).

The pressure relief gas drainage in goaf is the main control method of mine gas. This paper has been designed to study how to analyze and study the gas drainage of goaf pressure relief based on the perception layer of the Internet of Things. The intelligent evaluation of pressure relief gas drainage in goaf is described. This paper has raised the problem of gas extraction, which is based on the Internet of Things, so it has elaborated on the data-level fusion-related algorithms for sensing coal mine safety, and the case design and analysis of the prediction model and intelligent evaluation have been carried out. Aiming at the problem of intelligent grading of gas drainage evaluation in goaf, data preprocessing is performed on the drainage metering data. Using a deep learning evaluation method based on a convolutional neural network (CNN), an intelligent evaluation model is constructed for gas extraction. Compared with the classification model of the shallow neural network, the CNN classification model is more suitable for gas intelligence evaluation and has higher accuracy due to the good learning ability and accuracy of the deep neural network. When the learning rate is 0.1 and the batch is 256, the prediction effect of the CNN pressure relief gas intelligent classification model is the best, which can effectively provide classification results.

Published: September 2022

Computer searches of the PubMed, Cochrane Library, and Embase databases for randomized controlled studies on the effects of intensive nutrition on clinical outcomes in patients with severe craniocerebral injury were conducted from the time of database creation to June 11, 2022, along with manual searches of the relevant literature. Two investigators independently screened the literature, extracted data, and evaluated the risk of bias of the included studies before the effect sizes were combined using RevMan 5.3 statistical software provided by the Cochrane Collaboration Network, and publication bias was detected using Stata 12.0 software. Meta‐analysis showed that total protein levels were higher in the intensive nutrition group than in the regular nutrition group (WMD = 4.96 g/L (1.57‐8.34), P < 0.001); IgA levels were significantly higher in the intensive nutrition group than in the regular nutrition group (SMD = 0.79 (0.51‐1.07), P < 0.001; SMD = 0.98 (0.58‐1.38), P < 0.001); IgG levels were significantly higher in the fortified group than in the regular group (SMD = 0.98 (0.58‐1.38), P < 0.001); CD4/CD8 was significantly higher in the fortified patients than in the regular patients with a combined effect size of WMD = 0.33 (0.18‐0.48) (P < RR = 0.45 (0.27‐0.75), P = 0.002). The results show that effective support of early enteral nutrition can reduce the occurrence of gastrointestinal complications in patients, give them a better adaptation process to the gastrointestinal tract, and ensure the degree of tolerance of their gastric mucosa, thus absorbing more nutrition. Fortification significantly reduced the incidence of gastric retention in patients with craniocerebral injury (RR = 0.19 (0.07‐0.49), P < 0.001). In the subgroup analysis of the three groups, it was shown that, depending on the starting time, the total protein level and IgG level were better in the early nutrition at 24 h than in the late nutrition above 24h and that, depending on the starting dose, the total protein level, IgA, IgG, and CD4/CD8 were better in the intervention at doses above 30 mL/h, using the starting dose of 30 mL/h as the cut‐off point. In the subgroup analysis based on different nutrition methods (enteral and parenteral nutrition), IgA levels and the incidence of bloating and diarrhea were better than those of parenteral nutrition in the indicators of enteral nutrition.

Published: September 2022

Chronic obstructive pulmonary disease (COPD) is a respiratory disease that can be treated and prevented. The purpose of this paper is to conduct a meta-analysis of clinical rehabilitation nursing of COPD patients based on intelligent medical care by constructing a suitable model so as to make the research on clinical nursing of COPD patients more effective. This paper first introduced the intelligent medical system, analyzed the clinical rehabilitation nursing of COPD patients, established the SCNet model suitable for this paper, and then used statistical algorithms to carry out the meta dynamic analysis of the clinical rehabilitation nursing for COPD patients. Through the analysis of the current situation of medical equipment and the comparison of models and statistical analysis, the experimental results showed that the pulmonary function indexes of the pulmonary rehabilitation treatment group and the conventional treatment group were improved after treatment compared with before treatment. Although on specificity metrics SCNet did not perform the best, it was about 1% lower than the best baseline model. However, the comprehensive performance of the SCNet model on Acc, Sen, F1-Score, and AP indicators showed that the model SCNet proposed in this paper had certain advantages, which was helpful for the clinical rehabilitation care of patients with COPD and could better assist doctors in treatment.

Authors: Ding Song , Jiang Donglin , Zhou Hongyan
Published: September 2022

With the rapid development of industry, the production and demand of automobiles have increased significantly. The generation of cars often requires tens of thousands of processes, consisting of hundreds of assembly lines to complete. Chain conveyors are widely used in the transportation of automobile assembly lines. The existing conveyor chains are roller chains. With the improvement of the requirements for conveyor reliability, synchronization, and environmental friendliness, the characteristics of roller conveyor chains restrict the further development of chain conveyors. It is urgent to study a new conveyor chain system to improve the synchronization, reliability, and environmental friendliness of chain conveyors on hundreds of assembly lines. In this paper, the mathematical modeling, meshing analysis, reliability, and environmental friendliness of the parameters of the components of the double pitch time-sharing meshing toothed conveyor chain system are studied. In addition, a novel fault diagnosis method of double pitch time-sharing meshing toothed conveyor chain transmission system based on neural network model is proposed in this paper.

Published: September 2022

This study reports the effect of roasted pretreatment combined with screw press, hydraulic press, and Soxhlet extraction methods on various quality indexes of rapeseed and flaxseed oils, including the oil yield, sensory indexes (color, smell, clarity, viscosity, and colligation score), physicochemical properties (acid value, peroxide value, saponification value, moisture and volatiles), major components (fatty acid composition and triglyceride composition), and minor components (volatile compounds, total phenols, and vitamin E contents). The results indicated that the oil yield, sensory indexes, physicochemical properties, fatty acid composition, volatile compounds, total phenol, and vitamin E contents in vegetable oils have been significantly affected by different extraction methods. The yields of rapeseed and flaxseed oils of Soxhlet extraction method were increased by 30.10%–73.90% and 6.30%–54.40%, respectively, compared with other treatment groups. In addition, roasted pretreatment significantly increased the yields of oils by 4.10%–25.00% and 6.70%–23.15%, respectively, compared with the untreated group. The contents of linolenic acid and vitamin E in rapeseed and flaxseed oils extracted from screw press method were higher. In particular, the linolenic acid content of cold-pressed rapeseed oil extracted by screw press increased by 1.50%–23.80% compared with other treatment groups. In addition, the contents of vitamin E in cold-pressed rapeseed oil and flaxseed oil obtained by screw press increased by 1.22%–78.91% and 3.00%–18.80%, respectively. The Soxhlet extraction could improve oil yield and total phenol content, but the quality of the oil was inferior due to high acid values (0.93–3.36 mg KOH/g) and peroxide values (0.70–5.23 meq O2/kg). Furthermore, the hydraulic press method could extract vegetable oils with excellent sensory scores. The roasted pretreatment gives the rapeseed and flaxseed oils a good smell. The major volatile compounds in rapeseed and flaxseed oils were aldehydes, acids, alcohols, heterocycles, and ketones. Different extraction methods and pretreatment had no significant effect on the compositions and contents of triglycerides. This study provides a basic understanding on the selection of appropriate oil extraction techniques for oil extraction at a large scale.

Authors: Zhu Ailing
Published: September 2022

Since the 20th century, the resources and environment in Northeast China have changed, and it is one of the typical regions that have short‐term or high‐intensity environmental impacts in the world. However, due to the excessive consumption of regional resources and strong environmental pollution to the atmospheric environment, development is being greatly affected. Maintaining the natural ecological environment has become a very urgent task. This paper studies the important ecological environment problems in Northeast China from the perspective of double carbon goals. The study points out that there are ecological problems in Northeast China, such as the lack of forest resources, the aggravation of desertification, the decline of black soil quality, and the shrinkage of wetlands, which are severe urban environmental protection problems. At the same time, affected by the trend of world environmental change, policy drivers in Northeast China, and some relatively new environmental pollution problems, the natural environmental quality of Northeast China will still have a significant decline in the future. The future development of Northeast China will be based on the perspective of double carbon goals, constantly improve the ecological environment monitoring system, strengthen the research of scientific and technological system, strengthen innovation, and vigorously develop circular economy and further improve the construction of basic systems. Through a series of ecological environment governance and the coordinated development of economy and ecological environment, the dual growth of economy and ecological environment in Northeast China will be realized, and the overall revitalization of the old industrial zone in Northeast China will be realized.
[Retracted] Preliminary Evaluation of Artificial Intelligence‐Based Anti‐Hepatocellular Carcinoma Molecular Target Study in Hepatocellular Carcinoma Diagnosis Research
Authors: Wang Yuan , Wei Chao , Deng Xiangui , Gao Shudi , Chen Jing
Published: September 2022

In this paper, in‐depth research analysis of anti‐hepatocellular carcinoma molecular targets for hepatocellular carcinoma diagnosis was conducted using artificial intelligence. Because BRD4 plays an important role in gene transcription for cell cycle regulation and apoptosis, tumor‐targeted therapy by inhibiting the expression or function of BRD4 has received increasing attention in the field of antitumor research. Study subjects in small samples were used as the validation set for validating each diagnostic model constructed based on the training set. The diagnostic effect of each model in the validation set is evaluated by calculating the sensitivity, specificity, and compliance rate, and the model with the best and most stable diagnostic value is selected by combining the results of model construction, validation, and evaluation. The total sample was divided into a training set and test set by using a stratified sampling method in the ratio of 7 : 3. Logistic regression, weighted k‐nearest neighbor, decision tree, and BP artificial neural network were used in the training set to construct diagnostic models for early‐stage liver cancer, respectively, and the optimal parameters of the corresponding models were obtained, and then, the constructed models were validated in the test set. To evaluate the diagnostic efficacy, stability, and generalization ability of the four classification methods more robustly, a 10‐fold crossover test was performed for each classification method. BRD4 is an epigenetic regulator that is associated with the upregulation of expression of various oncogenic drivers in tumors. Targeting BRD4 with pharmacological inhibitors has emerged as a novel approach for tumor treatment. However, before we implemented this topic, there were no detailed studies on whether BRD4 could be used for the treatment of HCC, the role of BRD4 in HCC cell proliferation and apoptosis, and the ability of small molecule BRD4 inhibitors to induce apoptosis in hepatocellular carcinoma cells.
Risk Priority Evaluation for Power Transformer Parts Based on Intuitionistic Fuzzy Preference Selection Index Method
Authors: Minglin Jiang , Ren Haiping
Published: September 2022

The risk assessment of power transformer equipment can not only improve the safety and management level of transformer operation, but also reduce the operation and maintenance costs of the equipment on the basis of ensuring the overall reliable operation of the power system. As a result, it can enhance the rewards of assets investment. The quantitative analysis of power equipment risk often contains qualitative indicators that are difficult to quantify. These indicators have the characteristics of fuzziness. In order to improve the accuracy and reliability of risk assessment results, this paper proposed a new risk evaluation method based on intuitionistic fuzzy set. Firstly, language variables are transformed into corresponding intuitionistic fuzzy numbers. Secondly, a novel entropy of intuitionistic fuzzy set is established. Thirdly, a weighting method for determining each expert’s importance is proposed based on the new propose entropy. Furthermore, an extended preference selection index is put forward under intuitionistic fuzzy environment. Finally, an example of the risk assessment of power transformer components is discussed to illustrate the effectiveness of the new risk evaluation method.

Published: September 2022

Background. Hepatitis B virus (HBV) is still a major health problem worldwide, placing healthcare workers, medical and dental students, and professionals at higher occupational risk. The present study aimed to evaluate the level of knowledge about this virus and relevant safety precautions among dental students in the Kurdistan region of Iraq. Materials and methods. This cross‐sectional study was conducted among the third, fourth, and fifth stage dental students of Hawler Medical, Sulaimani, and Duhok universities. Data on the students’ demographic characteristics and their knowledge about HBV (16 close‐ended questions) and safety precaution measures (10 close‐ended questions) were collected by means of a questionnaire. Analysis of variance was used to compare the mean of knowledge and safety precaution scores. Results. In total, 372 students (mean age 21.77 ± 1.31 years) completed the questionnaires. The mean scores for knowledge and safety precautions were 13.17 ± 2.09 and 8.05 ± 1.61, respectively. Respondents from Hawler Medical University showed statistically significantly higher knowledge levels than their counterparts in Sulaimani and Duhok universities (p = 0.012). Conclusions. The majority of surveyed dental students are aware of HBV, its mode of transmission, infection, complications, vaccination, and safety precautions required to prevent the spreading of the virus. While the levels of knowledge about HBV and safety precautions among the dental students in the Kurdistan region of Iraq were generally acceptable, differences in knowledge level were identified between the universities, and these may be related to their educational and training programs.
[Retracted] Effects of Stress on Osteoblast Proliferation and Differentiation Based on Endoplasmic Reticulum Stress and Wntβ‐Catenin Signaling Pathway
Authors: Zhong Hanming , Yang Xiaoyu , Li Shitie , Lei Xin
Published: September 2022

In order to investigate the effect of fluid shear stress on the proliferation of osteoblasts and the regulatory role of the Wnt/β‐catenin signaling pathway in cell proliferation, a new method based on endoplasmic reticulum stress and Wnt/β‐catenin signaling pathway stress‐mediated was proposed. Taking MG63 osteoblasts as the research object, they were inoculated on glass slides (G group), polished titanium sheets (P group), and sandblasted acid‐base treated pure titanium sheets (S group). In addition, FSS of 0 dunes/cm2 (static group) and 12 dunes/cm2 (stress group) were given, respectively. Then, quantitative reverse transcription‐PCR (RT‐qPCR) and western blot were used to detect the mRNA and protein expressions of low‐density lipoprotein receptor‐related protein 5 (LRP5) and β‐catenin in MG63 cells. The results showed that the expression levels of β‐catenin mRNA and protein in cells in the stress group were significantly increased (P < 0.05), and the protein expression level of LRP5 was significantly decreased (P < 0.05). The expression level of LRP5 in group S was greatly inhibited, while the expression level of β‐catenin was significantly upregulated. Therefore, FSS can stimulate the expression of LRP5 and β‐catenin in osteoblasts. Fluid shear stress can promote osteoblast proliferation in vitro; the Wnt/β‐catenin signaling pathway is involved in regulating fluid shear stress to promote osteoblast proliferation.
Supply Chain Coordination with Capital-Constrained and Loss Aversion Retailer under Stochastic Demand and Supply
Authors: Yueli Lu , Lu Shi , Xueyun Zhao
Published: September 2022

In the face of increasingly complex market environment, supply chain members pay attention to the possibility of obtaining expected profits and various risks while considering profit maximization. The behaviors of decision makers are often influenced by their psychological preferences, and loss aversion is one of the basic characteristics of human economic behavior. We research the supply chain coordination problem with capital constraint and loss-averse retailer in the case of stochastic production and demand. In order to address the loss aversion, a novel utility function is structured according to the theory of mental account. Under wholesale price contract, the optimal expected utility of supply chain under decentralized decision is smaller than that under centralized decision due to the retailer’s constrained capital. Based on that, a model is constructed by making revenue sharing contract act as the dual role of supply chain coordination and delayed payment strategy without seeking external financing or internal financing, and the contract conditions and optimal decisions of the coordinated supply chain are solved. Theoretical analysis indicates that when the contract parameters are properly selected, even though the retailer’s capital is constrained, the revenue sharing contract can not only coordinate the supply chain but also realize the arbitrary distribution of supply chain profits within a certain range. Finally, the change of decision variables and expected utility or profit with contract parameters is analyzed by several numerical examples.

In order to improve the matching effect of environmental art color automatic matching, a model of environmental art color automatic matching based on visual matching is designed. Firstly, it preprocesses the color matching of environmental art, then extracts the color space and its main color, and analyzes the color deviation. At the same time, the color model is established and the color quantization is processed, and finally the color matching is realized. The experimental results show that the matching time of the proposed model is less than that of the traditional model, and the wrong contour is less. Research Objective. A model of environmental art color-automated matching based on visual matching is developed in order to improve the matching effect of environmental art color matching. Current Challenges. Because of time constraints, the matching model still has certain drawbacks, necessitating more optimization research in the subsequent study. The main steps in the research are pretreatment before color matching of environmental art, color space and main color extraction, color deviation analysis, color modeling, color quantization processing, implementation of color matching, and experimental comparison.

Published: September 2022

Introduction. Calcium silicate-based cements (CSCs) are frequently used in various endodontic procedures such as perforation repair, vital pulp therapy, regenerative treatments, or apexification. One of their areas of use, treatment of perforations, can be challenging in clinical practice. Selection of stable, durable, and compatible material with structural and biological alterations is a must in such situations. Aim. This study aimed to compare the dislocation resistance of various calcium-silicate-containing materials used in endodontic treatment exposed to various environmental conditions in a push-out study model. Methods. Selected ninety-six human mandibular premolars with single root canals were cut from the middle portion to obtain dentin slices of 2 mm thickness (n = 192). Then, the canal lumen was enlarged by using #4Gates-Glidden drills. Specimens for each repair material (MTA, Angelus, Endosequence RRM (ERRM), Biodentine, BioMTA) were placed in shaped lumens, wrapped in pieces of gauze, and randomly divided into four groups (n = 48) according to the storage time and media: group A: 4 days in phosphate-buffered saline (PBS), group B: 4 days in acetic acid (pH = 4.4), group C: 34 days in PBS, and group D: 4 days in acetic acid (pH = 4.4) followed by exposure to PBS for 30 days. A universal testing machine measured the dislodgement resistance followed by scanning electron microscopy imaging to evaluate the material-dentin interface. Results. ERRM showed the highest dislocation resistance in all test groups (

). The greatest bonding strength was observed (13,54 ± 5,56 MPa) after exposure to 34 days in PBS (pH = 7.2). The values for ERRM decreased in contact with acetic acid (pH = 4.4) and increased when placed in PBS (

). Conclusion. All repair materials showed a higher dislocation resistance when stored in PBS regardless of storage time. However, the improved pH of the surrounding media was not successful in reversing the deteriorating effect caused by lower pH in relation to dislocation resistance in all tested materials except for ERRM.
Exploration on the Role of Transformational Leadership Linkage Psychological Empowerment in Stimulating Employees’ Innovation Behavior in an Uncertain Environment: Based on Entrepreneurship Perspective
Authors: Wei Xiaoying , He Ying
Published: September 2022

Employee Innovative Behavior (EIB) in a stable environment is often based on the company’s planned policy orientation and has higher innovation performance under the transactional leadership behavior characterized by task orientation. In an uncertain environment, transformational corporate leadership behaviors will stimulate EIB. The essence of entrepreneurship is innovation. Enterprises provide employees with spiritual support through entrepreneurship, which can generate more effective long-term incentives for employees. From the perspective of entrepreneurship, based on the Uncertainty-Identity Theory (UIT), through the analysis of 287 pairs of valid sample data from 7 companies, it is found that Environmental Uncertainty (EU) has a positive moderating effect on the relationship between Transformational Leadership (TL) and Psychological Empowerment (PE). PE positively promotes EIB. The indirect effect size of PE is 0.2221, 0.3495, and 0.4450 from low to high, respectively. It is inferred that the interaction between TL and EU can positively promote EIB through the mediating effect of PE. The research conclusions expand the boundary conditions of the relationship between TL and EIB and innovatively provide theoretical guidance for the management of EIB from the perspective of entrepreneurship in an uncertain environment.

Cracked tooth syndrome is a commonly encountered disease in dentistry, which is often accompanied by dramatic painful responses from occlusion and temperature stimulation. Current clinical diagnostic trials include traditional methods (such as occlusion test, probing, cold stimulation, etc.) and X-rays based medical imaging (periapical radiography (PR), cone-beam computed tomography (CBCT), etc.). However, these methods are strongly dependent on the experience of the clinicians, and some inconspicuous cracks are also extremely easy to be overlooked by visual observation, which will definitely affect the subsequent treatments. Inspired by the achievements of applying deep convolutional neural networks (CNNs) in crack detection in engineering, this article proposes an image-based crack detection method using a deep CNN classifier in combination with a sliding window algorithm. A CNN model is designed by modifying the size of the input layer and adding a fully connected layer with 2 units based on the ResNet50, and then, the proposed CNN is trained and validated with a self-prepared cracked tooth dataset including 20,000 images. By comparing validation accuracy under seven different learning rates,

is chosen as the best learning rate for the following testing process. The trained CNN is tested on 100 images with

-pixel resolutions, which achieves an average accuracy of 90.39%. The results show that the proposed method can effectively detect cracks in images under various conditions (stained, overexplosion, images affected by other diseases). The proposed method in this article provides doctors with a more intelligent diagnostic solution, and it is not only suitable for optical photographs but also for automated diagnosis of other medical imaging images.

T-cell immunotherapy has demonstrated remarkable clinical outcomes in certain hematologic malignancies. However, efficacy in solid tumors has been suboptimal, partially due to the hostile tumor microenvironment composed of immune-inhibitory molecules. One such suppressive agent abundantly expressed in solid tumors is Fas ligand (FasL), which can trigger apoptosis of Fas-expressing effector cells such as T cells and natural killer (NK) cells. To alleviate this FasL-induced suppression of tumor-specific immune cells in solid tumors, we describe here the development of a Fas decoy that is secreted by engineered cells upon activation and sequesters the ligand, preventing it from engaging with Fas on the surface of effector cells. We further improved the immune-stimulatory effects of this approach by creating a Fas decoy and IL15 cytokine fusion protein, which enhanced the persistence and antitumor activity of decoy-engineered as well as bystander chimeric-antigen receptor (CAR) T cells in xenograft models of pancreatic cancer. Our data indicate that secreted Fas decoys can augment the efficacy of both adoptively transferred and endogenous tumor-specific effector cells in FasL-expressing solid tumors.
