    Abstract: The aim of the present work was to observe the activation/deactivation of cerebral functional regions after electroacupuncture (EA) at Yintang (EX-HN3) and GV20 by functional MRI (fMRI). Design A total of 12 healthy volunteers were stimulated by EA at Yintang and GV20 for 30 min. Resting-state fMRI scans were performed before EA, and at 5 and 15 min after needle removal. Statistical parametric mapping was used to preprocess initial data, and regional homogeneity (ReHo) and amplitude of low-frequency fluctuation (ALFF) were analysed. Results ReHo at 5 min post stimulation showed increases in the left temporal lobe and cerebellum and decreases in the left parietal lobe, occipital lobe and right precuneus. At 15 min post stimulation, ReHo showed increases in the left fusiform gyrus; lingual gyrus; middle temporal gyrus; postcentral gyrus; limbic lobe; cingulate gyrus; paracentral lobule; cerebellum, posterior lobe, declive; right cuneus and cerebellum, anterior lobe, culmen. It also showed decreases in the left frontal lobe, parietal lobe, right temporal lobe, frontal lobe, parietal lobe and right cingulate gyrus. ALFF at 5 min post stimulation showed increases in the right temporal lobe, but decreases in the right limbic lobe and posterior cingulate gyrus. At 15 min post stimulation ALFF showed increases in the left frontal lobe, parietal lobe, occipital lobe, right temporal lobe, parietal lobe, occipital lobe and cerebellum, but decreases in the left frontal lobe, anterior cingulate gyrus, right frontal lobe and posterior cingulate gyrus. Conclusions After EA stimulation at Yintang and GV20, which are associated with psychiatric disorder treatments, changes were localised in the frontal lobe, cingulate gyrus and cerebellum. Changes were higher in number and intensity at 15 min than at 5 min after needle removal, demonstrating lasting and strong after-effects of EA on cerebral functional regions.

    Abstract: This study aims to explore the effects of the social-emotional classroom climate on academic achievement in mathematics and literature for elementary students in grades 3 through 6. The research specifically focuses on the indirect role of creative thinking (convergent and divergent thinking). Structural equation modeling techniques were used to examine data collected from 1365 Chinese elementary students. The results indicate that in mathematics and literature classrooms, (1) the social-emotional climate had a positive effect on school achievement, and (2) divergent and convergent thinking play indirect roles between social-emotional climate and academic achievement. The findings suggest that elementary students’ positive perception of social-emotional classroom climate, including the perceptions of teacher support and student cohesiveness, can promote divergent and convergent thinking and ultimately contribute to the output of academic achievement in mathematics and literature.

    Abstract: This 5-year follow-up of the CCgenos cross-sectional study aimed to observe real-life outcomes in a cohort of 997 Han Chinese patients with chronic HCV infection and to explore the impacts of HCV genotype, patient characteristics and treatment status. Methods Clinical information and centralized HCV RNA measures were collected every 6/3 months for untreated/treated patients. Overall disease progression was defined as ≥1 of: de novo development of cirrhosis, Child-Turcotte-Pugh score increased by ≥2 points (if cirrhosis at baseline), progression to decompensated cirrhosis, hepatocellular carcinoma (HCC), liver transplant or death. Cox regression assessed risk factors for the time from estimated infection to cirrhosis or HCC. Logistic regression assessed risk factors for incidence rates of cirrhosis and overall disease progression. Results 281 of 514 patients enrolled across China completed 5 years of follow-up. Overall disease progression occurred in 36/364 (9.9%) treated patients and 35/148 (23.6%) untreated patients (odds ratio = 0.35; 95% CI 0.21, 0.59; P 〈 0.0001). Overall disease progression occurred in 6/231 (2.6%) patients achieving sustained virological response at 24 weeks (SVR24) versus 11/82 (13.4%) who did not ( P=0.0002). Cirrhosis development was significantly associated with abnormal aspartate aminotransferase (AST), age ≥40 years, body mass index ≥28 kg/m 2 , HCV GT1, platelet count 〈 100x10 9 /l, and AST to platelet ratio index (APRI) ≥2 (multivariate Cox regression, P 〈 0.05). HCC was significantly associated with HCV GT1 and platelet count 〈 100x10 9 /l (multivariate Cox regression, P 〈 0.05). Conclusions Achieving SVR24 significantly reduced the probability of overall disease progression but no significant difference was seen for both cirrhosis and HCC during 5 years of follow-up.

    Abstract: This study explored and evaluated the dimensions and consequences of esports online spectator demand. In doing so, we identified preliminary dimensions of esports online spectator demand based on semistructured interviews and online open-ended surveys. Findings resulted from the qualitative study were adopted as the foundation to develop the Scale for Esports Spectator Demand (SESD). To validate the SESD and assess the impact of the SESD factors on consumers’ cognitive and behavioral outcomes, a sample of esports online spectators ( N = 1,309) responded to a survey containing the SESD, which was randomly split into two halves, with one half for an exploratory factor analysis and the other half for a confirmatory factor analysis and structural equation modeling analyses. A total of 32 items under eight SESD factors were confirmed. While demand factors including commentary features, player characteristics, event attractiveness, and schedule convenience have been found in traditional sport contexts, chat room, streamer traits, stream quality, and virtual rewards appeared to be unique in esports. All eight SESD factors, excluding schedule convenience, were significantly predictive of one or more of the outcomes associated with esports consumption.

    In: Journal of Industrial Textiles, SAGE Publications, Vol. 52 ( 2022-08), p. 152808372211165-
    Abstract: Tetraethoxysilane (TEOS), γ- (methacryloyloxy) propyltrimethoxysilane (KH570) and ammonium pentaborate (AP, NH 4 B 5 O 8 ) were used as a precursor, silane coupling agent and flame retardant additive to prepare a series of single (SiO 2 ), composite (SiO 2 -KH570) and doped (SiO 2 -KH570-AP) sols via sol-gel processes. The sols were post finished to cotton fabrics through dipping-curing methods. Results show that as-prepared sol-gel systems are successfully deposited on cotton fabrics. SiO 2 -KH570-AP@COT shows the highest initial pyrolysis temperatures (296.4°C), char residue rate (31.5%), LOI (24.0%) and ΔLOI/Δm (4.75%/g), the most beneficial after-flame time (14.1 s) and after-glow time (0.0 s), the most complete char residue (30.0 cm), the second highest maximum pyrolysis temperature (356.6°C) and an effective synergistic effectiveness parameter ( 〉 1.0). Its flame retardancy is mainly promoted by both individually positive and jointly synergistic actions of silica sol (strong physical barrier and structural support effects in enhancing thermal stability and providing char frame), KH570 (strong coupling effect in combining components and reinforcing interface properties between components and cotton fibers) and AP (release of water molecules for cooling burning zone, diluting and isolating oxygen and gaseous products and promoting char formation). The flame-retardant treatment deteriorated the tensile strength of cotton fabrics.

    Abstract: For the purpose of effectively providing protection and utilization of historical earthen sites, the fully-enclosed exhibition halls with electricity driven air-conditioning have been successfully adopted to provide a suitable preservation air environment. However, its electricity consumption and carbon emissions are considerable due to the continuous operation of environmental control, the energy consumption of air cooling in exhibition halls can reach more than 10 times that of office buildings. To further reduce energy consumption, this current study drew on the concept of NBS (Nature Based Solution) and proposed a low-carbon environmental control system for an enclosed exhibition hall for storage of earthen relics by applying natural energy (solar photovoltaic and earth-air-cooling) and space optimization. Firstly, a numerical model was established to simulate the preservation environment in exhibition halls and the electricity consumption of each energy subsystem. Then the model was applied to optimize the design parameters (e.g. earth-air tunnel and airflow pattern) for the environmental control system. Numerical results showed that the electricity consumption was reduced by 58% by applying earth-air-cooling and solar photovoltaic. After optimization of the exhibition hall height, electricity consumption was approximately reduced by 65%. This research is of great value to mitigate energy consumption problems encountered in earthen relics museums and other similar environments.

    Abstract: Reasonable distribution of cooling load between chiller and ice tank is the key to realize the economical and energy-saving operation of ice-storage air-conditioning (ISAC) system. A multi-objective optimization model based on improved firefly algorithm (IFA) was established in this study to fully exploit the energy-saving potential and economic benefit of the ISAC system. The proposed model took the partial load rate of each chiller and the cooling ratio of the ice tank as optimization variables, and the lowest energy consumption loss rate and the lowest operating cost of the ISAC system were calculated. Chaotic logic self-mapping was used to initialize population to avoid falling into local optimum, and Cauchy mutation was used to increase the population’s diversity to improve the algorithm’s global search ability. The experimental results show that compared with the operation strategy based on constant proportion, particle swarm optimization (PSO) algorithm, and firefly algorithm (FA), the optimal operation strategy based on IFA can achieve more significant energy-saving and economic benefits. Meanwhile, the convergence accuracy and stability of the algorithm are significantly improved. Practical application: The optimized operation strategy of the ice-storage air-conditioning system can reduce energy loss and operating costs. The traditional operation strategies have the problems of low optimization precision and poor optimization effect. Therefore, this study presents an optimal operation strategy based on IFA. The convergence accuracy and stability of the algorithm are increased after the algorithm is improved. The operation strategy can get the maximum energy-saving effect and economic benefit of the ISAC system.

    Abstract: Early identification and timely management of septic AKI continue to represent clinical challenges for intensive care. The aim was to evaluate the effect of renal replacement with oXiris filter on clinical outcomes in septic AKI. Methods: This was a single-center randomized controlled trial that enrolled surgical septic shock with AKI patients admitted in the ICU, Renji Hospital, Shanghai Jiao Tong University, School of Medicine from Jan 1, 2021 to Sep 30, 2021, were screened. Results: Sixteen subjects that met the inclusion and exclusion criteria were randomized into CRRT with AN69-oXiris group ( n = 8) and AN69-ST group ( n = 8). The PCT and IL-6 concentration decreased significantly after the first treatment compared to pre-CRRT levels in the oXiris group (PCT: 23.46 [4.18, 84.90] vs 52.79 [9.03, 100.00]  µg/L, p = 0.046; IL-6: 3080.15 [527.62, 9806.61] vs 10,457.17 [8150.00, 15,528.87] pg/mL, p = 0.043). The levels of lactate decreased by 1.70 [1.03, 2.83] mmol/L after the first CRRT in the oXiris group ( p = 0.028). The norepinephrine infusion rate was decreased by 0.06 [0, 0.09] , 0.05 [0, 0.23] and 0.11 [0, 0.23] μg/kg/min at 4, 6, and 8 h in the oXiris group compared to the ST group ( p = 0.005, 0.038, and 0.017). Conclusion: Using the oXiris filter may improve hemodynamic status during initial CRRT in severe surgical septic shock with AKI. Further large multicenter RCTs are needed to determine the effect of the oXiris filter on patient outcomes. ( http://www.chictr.org.cn/index.aspx (ChiCTR2200055732)).

    Abstract: With the development of society, portal frame has been increasingly used in industrial buildings because of light weight, high degree of industrialization, and high economic efficiency. Some existing portal frames need to be reinforced and improved due to the expansion of production and the functional change. As a safe, reliable, and convenient reinforcement method, the external prestressing reinforcement technology is often used to reinforce the portal frame. In this paper, a new type of assembled anchoring joint was designed to connect the steel strand to the steel beam of a portal frame without damaging the original structure. The static loading test was performed by adjusting length of the strut. And the changes of strain and mid-span deflection were investigated. The Midas Gen FEM simulation was used to investigate stress characteristics of the reinforced portal frame, including strain, bending moment, shear force, etc. The experimental results and simulation results were compared to verify effectiveness of the designed joint. The results indicated the new prestressed anchoring joints had the advantages of simple structure, effectiveness, and force transfer path of the joints was clear. Therefore, the new prestressed anchoring joint can be applied to the external prestressing reinforcement of the portal frame.
