ABSTRACT Objectives: The aims of the present study were to compare the long-term outcomes for ascending aortic dilatation and adverse aortic events after isolated aortic valve replacement between patients with bicuspid aortic valve (BAV) and tricuspid aortic valve ( TAV). Methods: This retrospective study included 310 patients who had undergone isolated aortic valve replacement with an ascending aorta diameter ≤ 45 mm between January 2010 and September 2021. The patients were divided into BAV group (n=90) and TAV group (n=220). The differences in the dilation rate of the ascending aorta and long-term outcomes were analyzed. Results: Overall survival was 89 ± 4% in the BAV group vs. 75 ± 6% in the TAV group at 10 years postoperatively (P=0.007), yet this difference disappeared after adjusting exclusively for age (P=0.343). The mean annual growth rate of the ascending aorta was similar between the two groups during follow-up (0.5 ± 0.6 mm/year vs. 0.4 ± 0.5 mm/year; P=0.498). Ten-year freedom from adverse aortic events was 98.1% in the BAV group vs. 95.0% in the TAV group (P=0.636). Multivariable analysis revealed preoperative ascending aorta diameter to be a significant predictor of adverse aortic events (hazard ratio: 1.76; 95% confidence interval: 1.33 to 2.38; P<0.001). Conclusion: Our study revealed that the long-term survival and the risks of adverse aortic events between BAV and TAV patients were similar after isolated aortic valve replacement. BAV was not a risk factor of adverse aortic events. Objectives longterm long term (BAV TAV. .

Abstract Objective: To investigate the clinical implications of Golgi glycoprotein 73 (GP73) and granulocyte colony-stimulating factor (G-CSF) in children with bronchopneumonia (BP). Methods: Seventy-two children with BP (observation group) and 81 healthy children (control group) consecutively brought to the present study's hospital between June 2019 and October 2020 were enrolled. GP73 and G-CSF levels were determined to analyze their diagnostic value for pediatric BP. High-sensitivity C-reactive protein (hs-CRP) was also measured. The clinical implications of GP73 and G-CSF in pediatric BP complicated with respiratory failure and their connections with the inflammatory response were discussed. Results: GP73 and G-CSF levels were remarkably higher in the observation group (p< 0.05). The sensitivity and specificity of combined detection (GP73+G-CSF) in predicting pediatric BP were 72.22% and 86.42%, respectively (p < 0.001 ). GP73 and G-CSF, which are closely related to X-ray classification and complications in the observation group, decreased after treatment and were positively correlated with hs-CRP (p < 0.05), especially in children complicated with respiratory failure. Regression analysis identified the independence of the course of the disease, hs-CRP, X-ray classification, GP73, and G-CSF as influencing factors of respiratory failure in children with BP (p < 0.05). Conclusion: GP73 and G-CSF, with elevated levels in children with BP, are strongly linked to disease progression and are independent influencing factors of respiratory failure, which may be the key to diagnosing and treating pediatric BP in the future.

ABSTRACT >To quantitatively evaluate the effect of stubble height and mulching on soil resistance to wind erosion in protected cultivated chestnut soil farmland under different wind speed conditions, tests were carried out on conservation and conventional tillage in Mongolian Plateau, China, using a mobile wind erosion wind tunnel. Chestnut soils were a soil type in fragile semi-arid ecosystems that were susceptible to desertification following wind erosion and were found mainly in Central Asia and the North American continent. The results show that soil erosion on conservation tillage was lower than conventional tillage at different wind speeds. The resistance of conservation tillage to soil wind erosion increases with increasing stubble height and cover. At a stubble height of 300 mm and 50% cover, conservation tillage's average wind erosion resistance efficiency was 74.82%, effectively preventing wind erosion of agricultural soils.

Resumo Para avaliar quantitativamente o efeito da altura do restolho e da cobertura morta na resistência do solo à erosão do vento em terras cultivadas protegidas de castanheiros sob diferentes condições de velocidade do vento, foram realizados testes de conservação e lavoura convencional no planalto da Mongólia, China, utilizando um túnel móvel de vento de erosão do vento. Os solos de castanha são um tipo de solo em ecossistemas semi-áridos frágeis que são suscetíveis à desertificação após a erosão pelo vento e são encontrados principalmente na Ásia Central e no continente norte-americano. Os resultados mostram que a erosão do solo na lavoura de conservação é menor do que a lavoura convencional em diferentes velocidades de vento. A resistência da lavoura de conservação à erosão do solo pelo vento aumenta com o aumento da altura do restolho e da cobertura. Com uma altura do restolho de 300 mm e uma cobertura de 50%, a eficiência média de resistência da lavoura de conservação à erosão pelo vento é de 74,82%, evitando efetivamente a erosão pelo vento dos solos agrícolas.

ABSTRACT To provide an efficient and reliable calibration method with reduced time cost and increased accuracy, the angle of repose (AoR) in the simulation is batch-processed based on Python and the GA-BP neural network is used to improve the prediction accuracy of the DEM parameters of coated fertilizer particles. The single-factor test data were firstly interpolated to obtain sufficient training samples, thus avoiding the drawback that the BP network tends to fall into the local minimum during the training process. Then the GA-BP neural network was trained in combination with the orthogonal combination test, and the fitted correlation coefficients were all greater than 0.975, indicating that the algorithm has strong generalization performance and good stability. The predicted values matched the expected output values, indicating that the GA-BP neural network can accurately predict the nonlinear function output, and the network predicted output can be approximated as the actual output of the function. With the actual AoR as the output value, the simulation value of the AoR was obtained as 24.457° when the coefficient of restitution (CoR), coefficient of static friction (CoSF), and coefficient of rolling friction (CoRF) were 0.509, 0.176, and 0.0332, respectively, and the relative error with the actual value was 0.068%, indicating that the well-fitted GA-BP neural network could accurately predict the DEM parameters of fertilizer particles.

Abstract The conversion of sesamin to asarinin is a promising route for the production of asarinin. This work reports the affection of acid type and strength of the catalyst on the conversion of sesamin to asarinin and the effect of various reaction conditions in anhydrous ethanol using phosphotungstic acid (HPW) as catalyst. The experimental results indicate that the activity of sesamin conversion is determined by strong B acids. L acids are not active for the reaction, and do not show synergy with B acids for the formation of asarinin. Reaction time, HPW dosage and temperature have significant effects on sesamin conversion. A maximum asarinin yield of 57.93% was achieved. The reaction kinetics in the temperature range 55-75 °C were studied. The kinetic curves can be successfully fitted with an opposing first-order reaction model. The activation energy (Ea) for this reaction is found to be 105.2 ± 0.4 kJ/mol.

RESUMO Para construir um modelo de simulação acoplada da erosão eólica do solo e fluxo bifásico em regiões áridas e semi-áridas, os parâmetros de contato apropriados do modelo de simulação de elementos discretos do solo são obtidos com base no teste de calibração do ângulo de repouso (AoR). O modelo de simulação acoplado foi estabelecido através da combinação da dinâmica computacional dos fluidos. O valor de resposta da velocidade do vento de iniciação da areia foi usado para verificar a precisão do modelo. Devido às características dos solos áridos e semi-áridos, este trabalho usa o modelo de contato Hertz-Mindlin com JKR no software EDEM para calibrar os parâmetros do solo com base nos testes físicos do solo, e projeta o Plackett-Burman, a subida mais íngreme, e os testes Box-Behnken de acordo com o software Design-Expert para obter a regressão de segunda ordem do AoR do solo. Com o AoR 33,52° como alvo, obtém-se a melhor combinação de parâmetros: recuperação de colisão solo-solo 0,64, coeficiente de atrito estático solo-aço 0,31, energia de superfície JKR 3,302 J m-2. Finalmente, usando parâmetros calibrados e a velocidade do vento inicial como valor de resposta, o teste de fluxo de ar e vento sólido de duas fases foi conduzido em ANSYS Fluent e EDEM, com o erro relativo entre a velocidade do vento inicial registrada pela câmera de alta velocidade no teste de túnel de vento e a velocidade do vento inicial mostrada no modelo de simulação calculada em 8,7%, e os parâmetros calibrados do solo atenderam aos requisitos da simulação acoplada. Os resultados da simulação indicam que os parâmetros de calibração do solo podem ser utilizados para modelar a erosão do vento em duas fases do solo em ambientes semi-áridos.

ABSTRACT To construct a coupled simulation model of soil wind erosion and two-phase flow in arid and semiarid regions, the proper contact parameters of the soil discrete element simulation model are obtained based on the angle of repose (AoR) calibration test. The coupled simulation model is established by combining computational fluid dynamics. The response value of the wind speed of sand initiation is used to verify the model’s accuracy. Due to the characteristics of arid and semiarid soils, this paper uses the Hertz-Mindlin with JKR contact model in EDEM software to calibrate the soil parameters based on soil physical tests and designs the Plackett-Burman, steepest climb, and Box-Behnken tests according to Design-Expert software to obtain the soil AoR second-order regression. With the AoR of 33.52° as the target, the best combination of parameters is obtained: soil-soil collision recovery of 0.64, soil-steel static friction coefficient of 0.31, JKR surface energy of 3.302 J m-2. Finally, by using calibrated parameters and the threshold wind velocity as the response value, the wind-sand air-solid two-phase flow test is conducted in ANSYS Fluent and EDEM, with the relative error between the starting wind speed recorded by the high-speed camera in the wind tunnel test and the threshold wind velocity shown in the simulation model calculated to be 8.7%, and the calibrated soil parameters met the requirements of the coupled simulation.

Abstract Introduction: At present, there are few reports regarding the issue of aortic reoperation due to its complexity and high risk and individual differences among patients. Methods: From November 2016 to December 2017, the data from 35 cases of aortic reoperation at our institution, out of 212 consecutive aortic repairs, were reviewed. We retrospectively summarized and analyzed their surgical indications, operative data, time interval from previous aortic repair, and outcomes. The time intervals until reoperation were analyzed for differences. Results: Patients’ mean age was 40.9±14.5 years, and 25 of them were men (71.4%). The indications for reoperation were aortic valvular problem (14.3%), aneurysmal dilatation (25.7%), pseudoaneurysm formation due to anastomotic leakage (43.2%), and aortic dissection (17.1%). For patients who had underwent primarily emergency operations due to aortic dissection, the time interval until reoperation (4.8±3.2 years) was significantly shorter than that of the whole group (5.5±3.6 years, P<0.01). Among the 35 reoperations, Sun’s procedure was selected for 16 patients (45.7%) with total aortic arch reconstruction. The average follow-up was 12 months (range 9-15 months). Hospital mortality was 5.7% (two patients). Among the hospital survivors there were no cases of death, rupture of residual dissection, paraplegia, or central nervous system complications during the follow-up period. Conclusion: Patients with acute aortic dissection required repeat surgery significantly earlier compared to other diseases. As to reoperation strategy, we recommend Sun’s procedure as the choice for extended arch reconstruction since minimal effect on overall mortality and complication rates were found.

SUMMARY OBJECTIVE: This study aimed to explore the correlation between different body components and bone mineral density in healthy adults. METHODS: A total of 306 non-manual subjects, 161 males and 145 females, were selected from the physical examination center of our hospital from June to September 2019. They were divided into control group, overweight group, and obese group according to body mass index. The muscle mass and fat mass, body fat content, trunk fat mass, upper limb and thigh fat mass, bone density of femoral neck and lumbar vertebra, and bone mineral salt content of the whole body were measured by dual-energy X-ray absorptiometry. RESULTS: Body mass index, systolic blood pressure, diastolic blood pressure, femoral neck bone mineral density, bone mineral salt content, fat mass, muscle mass, upper limb fat mass, thigh fat mass, and trunk fat mass in the overweight group and obese group were all higher than those in the control group (P<0.05). The fat mass, muscle mass, upper limb fat mass, and trunk fat mass were positively correlated with the femoral neck bone mineral density, total lumbar vertebra bone mineral density, and bone mineral salt content (P<0.05). In addition, thigh fat mass was positively correlated with femoral neck bone mineral density and total lumbar spine bone mineral density, whereas body fat content was negatively correlated with bone mineral salt content. CONCLUSION: Body composition was related to bone mineral density and bone mineral salt content, and the correlation between different body composition indexes, and bone mineral density, and bone mineral salt content was different.

A novel recognition method was put forward to identify the producing areas of the flue-cured tobacco leaves rapidly and non-destructively by using a near-infrared (NIR) spectrometer and a multi-layer-extreme learning machine (ML-ELM) algorithm. In contrast to traditional linear discriminant analysis (LDA) and extreme learning machine (ELM) algorithms, the accuracy, sensitivity and specificity were the highest for the proposed ML-ELM algorithm. The ML-ELM models for different producing areas of Yunnan tobacco leaves had the best generalization ability and prediction results. Besides, the above three algorithms were also identified by using the chemical index data. The experimental results indicated that the NIR spectroscopy technology together with ML-ELM algorithm achieved the best prediction performance both using the NIR spectral data and chemical index data. It indicates that the combination of NIR and ML-ELM can recognize different producing areas of Yunnan tobacco leaves rapidly, accurately, and non-destructively.

Abstract This study looked at the inhibitory effects of Apocynum venetum tea flavonoids extract (AVTFE) on mouse glioma G422 cells. Through the use of high performance liquid chromatography, the flavonoids in AVTFE were examined (HPLC). Meanwhile, mice were injected with glioma G422 cells to create a mouse model of a transplanted tumor. AVTFE might significantly (P < 0.05) lower serum sIL-2R content and raise serum IFN-γ content in tumor-bearing mice, according to an analysis of mouse serum. In addition to reducing the rise in spleen weight and spleen index in mice brought on by transplanted tumors, AVTFE can limit the development of transplanted tumors in G422 cell mice. AVTFE can also boost immunity by encouraging T and B lymphocyte proliferation in tumor-bearing animals. AVTFE was therefore verified to have immunomodulatory properties and to limit the proliferation of glioma G422 cells.

ABSTRACT Soil moisture (SM) plays an important role in regulating the global water cycle, especially in arid areas, and is one of the main indicators of ecological environmental health. Although traditional methods can accurately measure SM at a single sample site, they are limited in large-scale and dynamic SM monitoring. Therefore, we used the Landsat images as the data source and the soil adjusted vegetation index (SAVI) to build the adjusted SAVI (aSAVI) index by modifying the soil adjustment parameter L and introducing the short-wave infrared band. According to the theory of temperature vegetation dryness index (TVDI) and feature space, we introduced a model, combined the measured SM data (Minqin Basin, China) through a comparative analysis of four vegetation indices (NDVI, SAVI, MSAVI, aSAVI) determine the optimal model. Taking the Minqin Basin as the study area, the spatiotemporal variation characteristics of SM in three sub-regions (the entire study area, irrigated region, and periphery of the irrigated regions) were quantitatively analyzed and compared in four different periods: pre-Comprehensive Treatment Program of the Shiyang River Basin (pre-CTSRB) (2000–2005), CTSRB I (2006–2010), CTSRB II (2011–2016), and CTSRB-end (2017–2021) to evaluate the ecological restoration effects of treatment programs from the SM perspective. The results showed that: 1) SM values derived from TVDI inversion and the aSAVI were more accurate, and the model sensitivity decreased with soil depth; 2) the mean value of SM fluctuated across the four periods but decreased slightly over the entire time series. The spatial variations of the SM were characterized by a “descending then ascending” trend. Soil moisture increased in 21.35 % of areas at 0.00-0.10 m in the past 22 years, and 59.66 % at 0.10-0.20 m. There was a negative correlation between the mean variation trend of SM and the percentage of area where SM fell in different periods; 3) the treatment program positively affected the ecological restoration of the Minqin Basin from the SM perspective. The area where SM increased was larger than that of decreasing SM, especially in 0.10-0.20 m soil layer. The increase can promote growth and confer resistance to desertification.

Abstract Objective To explore the molecular mechanism of neuropathologic damage induced by radiofrequency ablation at different temperatures. Methods This is basic research, and 36 SD rats were used to construct the neuropathological injury model. The rats were subjected to radiofrequency stimulation at different temperatures and were divided into 6 groups according to the temperature injury: 42°, 47°, 52°, 57°, 62°, and 67°C groups. Conduction time, conduction distance, and nerve conduction velocity were recorded after temperature injury. HE-staining was used to observe the histopathological morphology of the sciatic nerve. The expression of SCN9A, SCN3B, and NFASC protein in sciatic nerve tissue were detected by western blot. Results With the increase in temperature, nerve conduction velocity gradually decreased, and neurons were damaged when the temperature was 67°C. HE-staining showed that the degrees of degeneration of neurons in rats at 47°, 52°, 57°, 62°, and 67°C were gradually increased. The expression of SCN9A, SCN3B protein in 57°, 62°, 67°C groups were much higher than that of NC, 42°, 47°, 52°C groups. However, the expression of NFASC protein in 57°, 62°, 67°C groups was much lower than that of the NC, 42°, 47°, 52°C groups. Conclusion There was a positive correlation between temperature caused by the radiofrequency stimulation to neuropathological damage. The mechanism is closely related to the expression of SCN9A, SCN3B, and NFASC protein in nerve tissue caused by heat transfer injury.
