Abstract Objectives We aimed to explore the heterogeneity and differentiation trajectories of epithelial cells and NK/T-cells in Laryngeal Squamous Cell Carcinoma (LSCC). Methods We downloaded the GSE150321 data set containing LSCC01 and LSCC02 samples single cell RNA data from Gene Expression Omnibus. The UMAP analysis was performed to identify the cell subpopulations and cell locations of subpopulations. Seurat package was used to analyze the differential expression of genes. The function of differential expression genes was analyzed using DAVID database. The monocle2 package was used to analyze differentiation trajectories. We used the CellChat package to observe the signaling pathways and ligand-receptor pairs for epithelial cells and NK/T-cells. Results All the LSCC cells were divided into 16 subpopulation that included 7 epithelial cell subsets, 3 T-cell subsets. The function analysis indicated that epithelial cells and NK/T-cells mainly participated in different process, such as cell cycle, immune response, and cell migration. Then, the results of differentiation trajectory indicated that the ability of migration, and the activation of the immune system increases, while the ability of apoptosis, and glucose metabolic process decreases as pseudotime. Migration-related epithelial cells act on all T-cells via the CNTN2-CNTN2 ligand-receptor pair, which suggested that CNTN2 might be an important biomarker for regulating migration of epithelial cells. Conclusions Our study characterized the heterogeneity of LSCC, which provided novel insights into LSCC and identified a new mechanism and target for clinical LSCC threapies. Evidence IV.

SUMMARY: The myodural bridge is a dense connective tissue connecting muscles and ligaments to the spinal dura mater in the atlanto-occipital interspace. Some researchers believe that the myodural bridge may play a vital physiological role. It is possible, for instance, that the prevention of spinal dura mater infoldings might be involved in regulated cerebrospinal fluid circulation. For instance, it is possible to prevent spinal dura mater infoldings, regulating cerebrospinal circulation. Bats are nocturnal and the only mammals that can perform a genuine and sustained flight, whereas tree shrews are arboreal mammals that often climb to a high altitude of about 10,000 feet. Both animals have lifestyles that are different from other previously studied mammals. The study of these two animals will shed further light on the existence of the myodural bridge in mammals. Gross anatomical dissection was used to observe the connections between the deep muscles of the neck and the dura mater at the level of the atlanto-occipital interspace. The existing structures were analyzed using conventional and special histological staining techniques. The suboccipital regions in bats and tree shrews contained the rectus capitis dorsal major (RCDma), rectus capitis dorsal minor (RCDmi), oblique capitis anterior (OCA), and oblique capitis posterior (OCP). Dense connective tissue connects the RCDmi to the posterior atlanto-occipital membrane (PAOM) and the latter to the spinal dura mater. The myodural bridge in these mammals shares a similar structure to the myodural bridge in humans. Histological analyses confirmed that the connective fibers of the myodural bridge were primarily type I collagen fibers. In this study, it is supplemented by the existence of the myodural bridge in mammals. This further demonstrates that myodural bridge widely exists in the normal anatomy of mammals. This provides morphological support for a comparative anatomical study of the physiological function of the myodural bridge.

RESUMEN: El puente miodural es un tejido conjuntivo denso que conecta los músculos y los ligamentos a la duramadre espinal en el espacio atlanto-occipital. Algunos investigadores creen que el puente miodural puede desempeñar un papel fisiológico vital. Es posible, por ejemplo, que la prevención de los pliegues de la duramadre espinal pueda estar involucrada en la circulación regulada del líquido cefalorraquídeo. En esta instancia, es posible prevenir los pliegues de la duramadre espinal, regulando la circulación cerebro espinal. Los murciélagos son animales nocturnos y los únicos mamíferos que pueden realizar un vuelo real y sostenido, mientras que las musarañas arborícolas son mamíferos arbóreos que a menudo ascienden a una gran altura de unos 10 000 pies. Ambos animales tienen estilos de vida diferentes a los de otros mamíferos previamente estudiados. El estudio de estos dos animales ofrecerá más información sobre la existencia del puente miodural en los mamíferos. Se realizó una disección anatómica macroscópica para observar las conexiones entre los músculos profundos del cuello y la duramadre a nivel del espacio atlanto-occipital. Las estructuras existentes se analizaron mediante técnicas de tinción histológica convencionales y especiales. Las regiones suboccipitales en murciélagos y musarañas arbóreas presentaban el músculo recto dorsal mayor de la cabeza (RCDma), el recto dorsal menor de la cabeza (RCDmi), el oblicuo anterior de la cabeza (OCA) y el oblicuo posterior de la cabeza (OCP). El tejido conjuntivo denso conecta el RCDmi con la membrana atlanto- occipital posterior (PAOM) y esta última con la duramadre espinal. El puente miodural en estos mamíferos comparte una estructura similar al puente miodural en humanos. Los análisis histológicos confirmaron que las fibras conectivas del puente miodural son principalmente fibras de colágeno tipo I. Esto demuestra además que el puente miodural existe ampliamente en la anatomía normal de los mamíferos. Esta investigación proporciona apoyo morfológico para un estudio anatómico comparativo de la función fisiológica del puente miodural.

ABSTRACT Introduction: New-onset postoperative atrial fibrillation (POAF) is a common complication following coronary artery bypass grafting (CABG) surgery. Objective: To explore predictive factors and potential mechanisms of new-onset POAF in isolated off-pump CABG patients. Methods: Retrospective observational case-control study of 233 patients undergoing isolated off-pump CABG surgery between August 2018 and July 2020 at the Department of Thoracic and Cardiovascular Surgery, the Affiliated Drum Tower Hospital of Nanjing University Medical School. Associations between predictor variables and new-onset POAF were identified. The main outcome was new-onset POAF after CABG surgery. Results: A total of 75 (32.19%) patients developed new-onset POAF after CABG surgery. The new-onset POAF patients had advanced age, higher baseline systolic blood pressure, more preoperative use of diuretic drug, more transfusion of blood products, atrial dilation and postoperative positive inotropic drug treatment. Nineteen variates entered the multivariable logistic regression model with a Hosmer-Lemeshow test score of 7.565 (P=0.477). Postoperative left atrial enlargement, postoperative drainage in the first 24 hours and total length of hospital stay were statistically significant, while postoperative right atrial enlargement (OR and 95% CI, 7.797 [0.200, 304.294], P=0.272) and left atrial enlargement (3.524 [1.141, 10.886], P=0.029) assessed by echocardiography had the largest OR value. Conclusion: Atrial enlargement is strongly associated with new-onset POAF in patients with isolated off-pump CABG, thus it highlights the advantage of echocardiography as a useful tool for predicting new-onset POAF. Careful monitoring and timely intervention should be considered for these patients.

Abstract Exogenous additives applied for cigar tobacco leaves fermentation played an important role in sensory quality of cigar. In this study, effects of additives including coffee and cocoa on the quality of cigar tobacco leaves were explored. The changes of sensory quality, conventional chemical components, nonvolatile organic acids, and aroma compositions in tobacco leaves were studied. Results showed that the richness, mellowness and matureness of aroma, as well as the fluentness and sweetness of smoke in cigar were improved with the introduction of coffee or cocoa. According to chemical composition analysis, fermentation with coffee or cocoa increased the contents of alkaloids and sugar in tobacco leaves, which endowed the tobacco a relatively good performance on the sweetness and aroma richness. Besides, the decrease of citric acid, as well as the increase of saturated fatty acid and aroma components were found with additives, which was beneficial to improve the mellowness and aroma richness of cigar. It was suggested that coffee and cocoa exhibited positive effects on the chemical composition, especially increased the contents of sugar, saturated fatty acids and aromatic components, thus improving the sensory quality of tobacco leaves.

Abstract Wheat is the most widely cultivated food crop on the planet, and it feeds the majority of the world's population. The field experiment was performed from 2019 to 2021 in the eastern part of Loess Plateau, China Nitrogen (N) fertilizer application improves winter wheat yield. It was necessary to analyze the nitrogen utilization of different varieties and screen varieties with high yield and high nitrogen utilization. Six dryland wheat varieties YH-20410, YH-618, YH-805, JM-92, C-6359, and LH-6 were selected to compare the differences in nitrogen uptake and utilization yield, and quality. The aim was to provide theoretical basis for high yield, and high-efficiency wheat production in dryland of southeast loess Plateau. The results showed that the rainfall during the fallow period from 2019 to 2021 was 245.5 mm and 288.9 mm, respectively, and the nitrogen application rate was 180 kg ha-1.The highest transshipment amount, and transshipment rate of nitrogen before anther were found in YH-618, which reached 79.4 kg ha-1 and 58.6%, respectively. The yield of wheat cultivar YH-20410 was the highest, reaching 4890 kg ha-1, which was significantly higher than that of YH-805, JM-92, C-6359 and LH-6, but there was no significant difference of YH-618. The grain protein content of YH-618 was the highest (15.2%), which was not significantly different from that of JM-92, YH-805 and LH-6, but significantly higher than that of YH-20410, and C-6359, respectively. Therefore, in high-yield years, fallow cultivation can help adjust the relationship among the components, promote a reasonable distribution, and improve yield.

ABSTRACT In order to make full use of aged asphalt, a light oil regenerant for cold mixing was prepared in this paper, and the ratio of regenerant and regeneration effect was studied through the performance test of recycled asphalt. The ratio of regenerant was determined by 60 °C kinematic viscosity, mass loss before and after aging, and asphalt three indicators. The thermogravimetric analysis determined the four-component ratio of recycled asphalt, and the mechanical properties of the recycled asphalt mixture were determined by the 15 °C splitting and 20 °C compression tests. Finally, the road performance of the recycled asphalt mixture was analyzed by rutting, low-temperature bending, and dry-wet splitting tests. When the mass ratio of light base oil: plasticizer: stable equilibrium agent: penetrant: the anti-aging agent is 80:20:25:8:5, it has a good regeneration effect. After adding 8% regenerant, the regenerated asphalt is compared with the recycled asphalt. The content of saturates and aromatics increases, and the content of resins and asphaltenes decreases. The four-component content of recycled asphalt is close to that of new asphalt. The mechanical properties test shows that the optimum content of the regenerant is 0.9%. With increased RAP content, the water stability and low-temperature crack resistance are also improved, and the high-temperature stability is reduced. However, it still meets the requirements of the regeneration specification.

Abstract Objective To develop a health education mode based on the theory of planned behavior (TPB), and to explore the influence of this mode on the postoperative lifestyle of patients with cervical cancer. Methods A total of 122 patients diagnosed from January 2019 to June 2020 were divided into control and education groups (n=61) using a random number table. Control group received traditional health education after operation, while education group was given TPB-based health education after operation. Their general data, medication compliance, dietary compliance, discharge time, incidence of complications, lifestyle, quality of life (QOL) and mental state before and after operation were compared. Results No significant differences were found in general data, preoperative lifestyle score, QOL score and mental state score between the two groups (P>0.05). In education group, the medication compliance and dietary compliance scores were significantly higher than those in control group, while the discharge time and the total incidence of complications were earlier and lower than those in control group (P<0.05). After operation, the scores of self-realization, interpersonal relationship, nutrition, physical activity, health responsibility, stress management, physical dimension, social/family dimension, emotional dimension and functional dimension significantly rose, while the distress thermometer and problem list scores declined in both groups, and education group had better improvement in scores than control group (P<0.05). Conclusion Theory of planned behavior health education mode can improve the postoperative treatment compliance, reduce postoperative complications, and ameliorate the lifestyle, quality of life and mental state of patients with cervical cancer.

Abstract Motor bearings are prone to different degrees of performance degradation, fatigue damage and failure undergoing complex and harsh environments. Vibration signal analysis is a mature method for diagnosing motor bearing faults, while it is not applicable for installing additional vibration sensors on many occasions. Practically, the fault of motor bearings changes the air gap flux between the rotor and stator, which leads to harmonic fluctuations in the stator current. The current signals can be used to diagnose the motor bearing faults without additional sensors. Inevitably the harmonics caused by the motor bearing faults will be coupled with the original signals. This paper combines bi-spectrum and Convolution Neural Network (CNN) to analyze the current signals of motor bearing faults. The CNN diagnosis model is trained based on the local bi-spectrum of current, and the CNN parameters are optimized. Diagnose and analyze motor bearing faults with different fault implantation methods, working conditions, fault degrees and fault locations. The diagnostic accuracy reaches more than 80%.

SUMMARY Here, we report the clinical observations of two Chinese fraternal twins who presented with severe dehydration, poor feeding, and absence of stimuli responses within a few days of birth. Trio clinical exome sequencing of the family identified compound heterozygous intronic variants (c.1439+1G>C and c.875+1G>A) in SCNN1A gene in these two patients. Sanger sequencing results showed that the c.1439+1G>C variant was inherited from the mother, and c.875+1G>A from the father, rarely reported in pseudohypoaldosteronism type 1 with sodium epithelial channel destruction (PHA1b) patients. Case 2 received timely symptomatic treatment and management after obtaining these results, which improved the clinical crisis. Our results suggest that the compound heterozygous splicing variants in SCNN1A were responsible for PHA1b in these Chinese fraternal twins. This finding extends the knowledge of the variant spectrum in PHA1b patients and highlights the application of exome sequencing in critically ill newborns. Finally, we discuss supportive case management, particularly in maintaining blood potassium concentration.

ABSTRACT In the process of rice harvesting, the passability of the track combine harvester is often limited by the state of the soil. Meanwhile, wet and soft paddy soil is compacted under the rolling of harvesting machinery, which also affects the soil function and the ecological environment. Therefore, the relationship between the physical and mechanical properties of wet and soft paddy soil was studied in this paper. In addition, compaction from a track combine harvester on field soil with and without rice stubble was studied. The density and gradation of wet and soft paddy soil were positively correlated with cohesion and negatively correlated with the internal friction angle. In paddy soil with a moisture content of 16–36%, the soil moisture content was negatively correlated with cohesion and internal friction angle. Additionally, the plastic deformation of soil with rice stubble under compaction was greater than that without rice stubble, and the plastic deformation of the field with rice stubble mainly occurred in the second rolling stage. Increasing the speed of the track combine harvester effectively reduced the compaction risk of rice stubble soil.

Abstract The higher acidity in fruits compared with grapes was one of the main obstacles to producing high-quality fruit wines. In the present research, the effect of the split batch fermentation pattern on the metabolites of greengage wines was investigated. This fermentation pattern included whole fruit immersion in the sucrose and coculturing Saccharomyces bayanus Y4 with Torulaspora delbrueckii Y7. These results showed that the contents of total acidity and dominant organic acids were significantly reduced among the batches. Aliphatic compounds were decreased with the batches, while aromatic compounds that contributed to flavor improvement were increased oppositely. The acetate esters, ketones, and terpenes contents were significantly increased in the first batch of coculture. In addition, acidic stress largely affected the kinetics characteristics of greengage wine on a pilot scale. Interestingly, the increment of total acidity was closely associated with the rate of total sugar consumption, which was affected by microbial activities. The acidity content was significantly declined and distinct flavour profiles were formed in split batch and coculture fermentation of greengage wines. It provides a new avenue to enhance the flavor and quality of fruit wines. highquality high research investigated Y Y7 batches oppositely esters ketones addition scale Interestingly consumption activities

ABSTRACT To explore the functions of Txnip and its mechanism in adipocyte differentiation, the preadipocytes were isolated from subcutaneous adipose tissue of three-day-old piglets and induced into adipogenic differentiation. The expression of Txnip and ChREBP was silenced, and the Txnip overexpression was achieved in the cells with transfection of the recombinant lentivirus strategies. Txnip silencing promoted the differentiation of porcine preadipocytes and PPARγ expression, and a PPARγ inhibitor reduced this facilitation. Instead, Txnip overexpression exerted a suppressive effect on the cell differentiation and PPARγ expression, and the PPARγ agonist offset this inhibition. High glucose stimulated the preadipocyte differentiation and expressions of ChREBP and Txnip. In contrast, Txnip expression was reduced by ChREBP silencing, suggesting glucose-regulated Txnip expression through the mediation of ChREBP. Moreover, the expressions of ChREBP and Glut4 induced by high glucose and glucose uptake of the cells were reduced by Txnip-overexpression, but increased by Txnip silencing, while these changes of Txnip did not alter their expressions under low glucose. Collectively, Txnip could be an inhibitor of porcine preadipocyte differentiation, which attenuated the adipogenesis through the negative feedback regulation on PPARγ. Txnip impaired the induction of glucose on the preadipocyte differentiation through decreasing Glut4 expression and glucose uptake and subsequent decrease of the expression and transcriptional activity of ChREBP. threedayold three day old silenced strategies facilitation Instead inhibition contrast glucoseregulated regulated Moreover Glut Txnipoverexpression, Txnipoverexpression overexpression, Txnip-overexpression Collectively
