The role of joint entity and relation extraction is to identify entities and their corresponding relations from specific texts, and it is also the basis for constructing and updating knowledge graph. Currently, joint extraction methods ignore information redundancy in the extraction process while pursuing performance. To address this issue, a model based on latent relations for joint entity and relation extraction is proposed. This paper designs a new decoding method to reduce the redundant information of relationships, entities and triples in the prediction process, and it is divided into two steps: extracting potential entity pairs and decoding relationships to complete the extraction of triples. Firstly, the potential entity pair extractor is used to predict whether there is potential relationship between entities, and at the same time, the entity pairs with high confidence are selected as the final potential entity pairs. Secondly, the relational decoding is regarded as a multi-label binary classification task, and the confidence of all relationships between each potential entity pair is predicted by the relational decoder. Finally, the number and type of relationships are determined by confidence to complete the task of extracting triples. Experimental results on two general datasets show that the proposed model is better than the baseline models in terms of accuracy and F1 indicators, which verifies the effectiveness of the proposed model. The ablation experiment also proves the effectiveness of the internal parts of the model.

FKBP4, a member of the FK506-binding protein (FKBP) family, is a promising target for a variety of disorders, including cancer. However, its underlying molecular mechanism and potential function in hepatocellular carcinoma (HCC) are largely elusive. Therefore, we aimed to investigate the expression status, functional implications and underlying mechanisms of FKBP4 in HCC. Our bioinformatics analysis of TCGA LIHC datasets, ICGC LIRI-JP datasets and GEO datasets results showed FKBP4 was upregulated in HCC tissues. We also confirmed the elevated FKBP4 in clinical HCC samples. Additionally, quantitative RT-PCR results revealed FKBP4 was highly expressed in all five tested HCC cell lines. We also observed a correlation between elevated FKBP4 expression and poor prognosis in HCC patients. Loss of FKBP4 can inhibit the proliferation and migration in HCC cells. Furthermore, we found that silencing FKBP4 suppressed glucose uptake, lactic acid production and
18 F-FDG uptake compared with the control group. Mechanistically, our funding indicated that FKBP4 participates in glycolysis through p53 mediated HK2 signaling pathway, specially, FKBP4 knockdown promotes the expression and stability of p53 protein rather than affecting the transcription level. Finally, rescue experiments revealed that simultaneous knockdown of both FKBP4 and p53 partially reversed the inhibitory effects on HK2 protein levels and18 F-FDG uptake. Our study elucidates a novel role of FKBP4 in promoting HCC development and glycolysis by modulating the p53/HK2 signaling pathway. Given the critical role of aerobic glycolysis in the progression of HCC, targeting FKBP4 may offer a new therapeutic strategy for treating this malignancy. [ABSTRACT FROM AUTHOR]- Published

High-k oxide dielectric films are indispensable for low-power-consumption oxide thin-film transistors (TFTs) applied in advanced and portable electronics. However, high-quality oxide dielectric films prepared by solution process typically require sophisticated processes and long thermal annealing time, severely limiting both the throughput manufacturing and cost-effectiveness. In this study, the influence of different heating-up methods on the surface morphology and dielectric properties was systematically investigated. Gradient heating-up method could not only substantially improve the surface morphology and quality of high-k ZrO
2 films but also efficiently shorten the annealing time. The gradient heating-up process was further designed on the basis of thermal behavior of the xerogel-like precursor, which successfully realize the preparation of high-quality ZrO2 films with an annealing time of 5 min (i.e. the efficiency of thermal treatment increased by about 89%). The ZrO2 film presented excellent dielectric properties, including a low leakage current density of ∼10−8 A cm−2 (at 2 MV cm−1 ), a large areal capacitance of 169 nF cm−2 and a high dielectric constant of 20.41 (1 MHz). Furthermore, InSnZnO TFT based on the ZrO2 gate dielectrics shows an acceptable device performances, such as a high carrier mobility of 2.82 cm2 V−1 s, a high on/off current ratio of ∼105 and a low subthreshold swing of 0.19 V decade−1 at a low operation voltage of 5 V. This work provide a highly promising approach to fabricate high-quality solution-processed high-k oxide dielectric films employed for large-scale and low-power-consumption electronics.

Summary: Salinity, as one of the most challenging environmental factors restraining crop growth and yield, poses a severe threat to global food security. To address the rising food demand, it is urgent to develop crop varieties with enhanced yield and greater salt tolerance by delving into genes associated with salt tolerance and high‐yield traits. MiR396b/GRF6 module has previously been demonstrated to increase rice yield by shaping the inflorescence architecture. In this study, we revealed that miR396b/GRF6 module can significantly improve salt tolerance of rice. In comparison with the wild type, the survival rate of MIM396 and OE‐GRF6 transgenic lines increased by 48.0% and 74.4%, respectively. Concurrent with the increased salt tolerance, the transgenic plants exhibited reduced H2O2 accumulation and elevated activities of ROS‐scavenging enzymes (CAT, SOD and POD). Furthermore, we identified ZNF9, a negative regulator of rice salt tolerance, as directly binding to the promoter of miR396b to modulate the expression of miR396b/GRF6. Combined transcriptome and ChIP‐seq analysis showed that MYB3R serves as the downstream target of miR396b/GRF6 in response to salt tolerance, and overexpression of MYB3R significantly enhanced salt tolerance. In conclusion, this study elucidated the potential mechanism underlying the response of the miR396b/GRF6 network to salt stress in rice. These findings offer a valuable genetic resource for the molecular breeding of high‐yield rice varieties endowed with stronger salt tolerance. [ABSTRACT FROM AUTHOR]

Employing deep learning techniques for the semantic segmentation of remote sensing images has emerged as a prevalent approach for acquiring information about water bodies. Yet, current models frequently fall short in accurately extracting water bodies from high-resolution remote sensing images, as these images often present intricate details of terrestrial objects and complex backgrounds. Vegetation, shadows, and other objects close to water boundaries have increased similarity to water bodies. Moreover, water bodies in high-resolution images have different boundary complexities, shapes, and sizes. This situation makes it somewhat challenging to accurately distinguish water bodies in high-resolution images. To overcome these difficulties, this paper presents a novel network model named EU-Net, specifically designed to extract water bodies from high-resolution remote sensing images. The proposed EU-Net model, with U-net as the backbone network, incorporates improved residual connections and attention mechanisms, and designs multi-scale dilated convolution and multi-scale feature fusion modules to enhance water body extraction performance in complex scenarios. Specifically, in the proposed model, improved residual connections are introduced to enable the learning of more complex features; the attention mechanism is employed to improve the model's discriminative ability by focusing on important channels and spatial areas. The implemented multi-scale dilated convolution technique enhances the model's receptive field while maintaining the same number of parameters. The designed multi-scale feature fusion module is capable of processing both small-scale details and large-scale structures in images, while simultaneously modeling the spatial context relationships of features at different scales. Experimental results validate the superior performance of EU-Net in accurately identifying water bodies from high-resolution remote sensing images, outperforming current models in terms of water extraction accuracy.

Introduction: The popular traditional Chinese medicine (TCM) compound FYTF-919 (Zhong Feng Xing Nao prescription) may improve outcome from acute intracerebral hemorrhage (ICH) through effects on brain edema, hematoma absorption, and the immune system. This study is to assess whether FYTF-919 is safe and effective as compared to matching placebo treatment in patients with acute ICH. Methods: The ongoing Chinese Herbal medicine in patients with Acute INtracerebral hemorrhage (CHAIN) is a multicenter, prospective, randomized, double-blind placebo-controlled trial of FYTF-919 in patients with acute ICH at 20–30 hospital sites in China. Eligible ICH patients presenting within 48 h after symptom onset are randomly allocated to receive either FYTF-919 (100 mL per day × 28 d, oral) or matching placebo. A sample size of 1,504 patients is estimated to provide 90% power (α 0.05) to detect a ≥20% improvement in average utility-weight scores on the modified Rankin scale (UW-mRS) assessed at 90 days, with 6% non-adherence and 10% lost to follow-up. The primary efficacy outcome is UW-mRS at 90 days. Secondary outcomes include binary measures of the mRS, neurological impairment on the National Institute of Health Stroke Scale, and health-related quality of life on the EuroQol EQ-5D-5L scale at different time points over 6 months of follow-up. The key safety measure is serious adverse events. Conclusion: CHAIN is on schedule to provide reliable evidence over the benefits of a popular herbal TCM for the treatment of acute ICH.

Background: The aim of the present study was to evaluate the impact of intratumoral metabolic heterogeneity and quantitative 18F‐FDG PET/CT imaging parameters in predicting patient outcomes in thymic epithelial tumors (TETs). Methods: This retrospective study included 100 patients diagnosed with TETs who underwent pretreatment 18F‐FDG PET/CT. The maximum and mean standardized uptake values (SUVmax and SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) on PET/CT were measured. Heterogeneity index‐1 (HI‐1; standard deviation [SD] divided by SUVmean) and heterogeneity index‐2 (HI‐2; linear regression slopes of the MTV according with different SUV thresholds), were evaluated as heterogeneity indices. Associations between these parameters and patient survival outcomes were analyzed. Results: The univariate analysis showed that Masaoka stage, TNM stage, WHO classification, SUVmax, SUVmean, TLG, and HI‐1 were significant prognostic factors for progression‐free survival (PFS), while MTV, HI‐2, age, gender, presence of myasthenia gravis, and maximum tumor diameter were not. Subsequently, multivariate analyses showed that HI‐1 (p < 0.001) and TNM stage (p = 0.002) were independent prognostic factors for PFS. For the overall survival analysis, TNM stage, WHO classification, SUVmax, and HI‐1 were significant prognostic factors in the univariate analysis, while TNM stage remained an independent prognostic factor in multivariate analyses (p = 0.024). The Kaplan Meier survival analyses showed worse prognoses for patients with TNM stages III and IV and HI‐1 ≥ 0.16 compared to those with stages I and II and HI‐1 < 0.16 (log‐rank p < 0.001). Conclusion: HI‐1 and TNM stage were independent prognostic factors for progression‐free survival in TETs. HI‐1 generated from baseline 18F‐FDG PET/CT might be promising to identify patients with poor prognosis. [ABSTRACT FROM AUTHOR]

- Abstract
Many current fault diagnosis methods tend to ignore the temporal correlation in signals, leading to a loss of critical fault information. Additionally, traditional diagnostic models often face challenges in terms of noise immunity, generalization, and handling non-Euclidean structured data. To address these issues, we propose a novel fault diagnosis approach that combines graph neural networks (GNNs) with the Markov transform field (MTF). We first use the MTF to convert vibration signals into 2-D images, preserving temporal correlation and preventing the loss of crucial fault information. Next, we use a graph convolutional neural network (GCN) to process graph-structured data, capturing global structural information. Finally, we introduce the graph attention network (GAT) to dynamically adjust node weights based on their relative importance, enhancing the overall model performance. In this article, we introduce a new fault diagnosis model, GCN-GAT, and evaluate it using the CWRU bearing dataset and a custom-built planetary gearbox dataset. The results show that our model maintains high fault detection accuracy even in the presence of significant noise and variable load conditions. This indicates that our approach demonstrates strong robustness and generalization, providing an effective solution for complex fault diagnosis tasks.

There is little research on the relationship between phthalates exposure and sleep problems in adult females, with existing studies only assessing the association between exposure to individual phthalates with sleep problems. We aimed to analyse the relationship between phthalates and sleep problems in 1366 US females aged 20 years and older from the 2011-2014 National Health and Nutrition Examination Survey (NHANES) by age stratification. Multivariate logistic regression showed that the fourth quartile of MECPP increased the risk of sleep problems in females aged 20–39 compared with the reference quartile (OR: 1.87, 95% CI: 1.14, 3.08). The WQS index was significantly associated with the sleep problems in females aged 20–39. In the BKMR, a positive overall trend between the mixture and sleep problems in females aged 20–39. In this study, we concluded that phthalates might increase the risk of sleep problems in females aged 20–39. [ABSTRACT FROM AUTHOR]

This article explores the dissipative control of two‐dimensional (2‐D) discrete‐time switched Fornasini–Marchesini local state‐space systems under dwell‐time switching. It introduces a new point‐dependent convex storage function to establish the criteria for the asymptotic stability and strict (Q,S,R)$$ \left(Q,S,R\right) $$‐β$$ \beta $$‐dissipativity of the 2‐D switched Fornasini–Marchesini local state‐space model based on LMIs. From these established findings, special cases of dissipative control such as strict passivity and H∞$$ {H}_{\infty } $$ performance can be derived. The article also presents the design of a state feedback point‐dependent convex controller using the proposed storage function approach, along with a sufficient condition for the dissipativity of the closed‐loop system. Finally, several examples are presented to corroborate the effectiveness and superiority of the proposed method. [ABSTRACT FROM AUTHOR]

- Abstract
This paper proposes a synthetical multi-degree-of-freedom mathematical modelling for analyzing the dynamic characteristics of angular contact ball bearing with waviness subjected to the external load working conditions. The above multi-degree-of-freedom mathematical modelling is established based on nonlinear elastic Hertz contact theory and inner raceway control theory by employing improved Newton–Raphson iteration method; the validation of the established mathematical modelling is verified by comparing the presented results with the existing literature results. The above mathematical modelling has considered raceway waviness, ball waviness, bearing clearance, centrifugal force, gyroscopic moment, external loads, and rotating speed comprehensively. Firstly, the effects of waviness order and waviness amplitude on time-varying contact and stiffness characteristics of angular contact ball bearing are investigated systematically. Then, the influences of bearing clearance, rotating speed, axial force, radial force, and torque on the dynamic contact and stiffness characteristics of angular contact ball bearing with waviness are analyzed thoroughly. The main results show that the solution results of mathematical modelling have converged, respectively, when raceway waviness order increases to 25 and ball waviness order increases to 5; The variation tendencies of time-varying contact angle, contact force, and stiffness of angular contact ball bearing with waviness are aperiodic; The amplitudes of time-varying contact angle, contact force, and stiffness of angular contact ball bearing increase evidently with waviness amplitude increased; The bearing clearance has important influence on the contact angle and contact force of outer raceway and inner raceway, respectively; The effects of radial force and torque on contact and stiffness characteristics are consistent basically in the corresponding direction; The influences of axial force and rotating speed on the contact and stiffness characteristics are more remarkable compared with other factors. The investigations of contact and stiffness characteristics of angular contact ball bearing with waviness are helpful for the designation and manufacture of high precision angular contact ball bearing.

- Abstract
High-voltage circuit breakers are the core equipment in power networks, and to a certain extent, are related to the safe and reliable operation of power systems. However, their core components are prone to mechanical faults. This study proposes a component separation method to detect multiple mechanical faults in circuit breakers that can achieve online real-time monitoring. First, a model and strategy are presented for obtaining mechanical voiceprint signals from circuit breakers. Subsequently, the component separation method was used to decompose the voiceprint signals of multiple faults into individual component signals. Based on this, the recognition of the features of a single-fault voiceprint signal can be achieved. Finally, multiple faults in high-voltage circuit breakers were identified through an experimental simulation and verification of the circuit breaker voiceprint signals collected from the substation site. The research results indicate that the proposed method exhibits excellent performance for multiple mechanical faults, such as spring structures and loose internal components of circuit breakers. In addition, it provides a reference method for the real-time online monitoring of high-voltage circuit breakers.

Background A paucity of evidence exists regarding the optimal management for abdominal aortic graft infection. The aim of this paper was to assess short- and long-term outcomes following different surgical options in aortic graft infection patients. Methods Medline, Embase and the Cochrane Library were searched from inception to February 2023. Network meta-analysis was performed using a frequentist method. Patients were divided into four treatment groups: complete graft removal with in situ repair, complete graft removal with extra-anatomic repair, partial graft removal with in situ repair and partial graft removal with extra-anatomic repair. The mortality rate at 30-days and 1-year was the primary outcome. Secondary outcomes were longer-term mortality rate, primary patency and reinfections. For included RCTs, the Cochrane risk-of-bias tool was utilized to assess the risk of bias. The methodological quality of cohort studies was evaluated using the Newcastle–Ottawa scale. Results Among 4559 retrieved studies, 22 studies with 1118 patients (11 multi-arm and 11 single-arm studies) were included. Patients received complete graft removal with in situ repair (N = 852), partial graft removal with in situ repair (N = 36), complete graft removal with extra-anatomic repair (N = 228) and partial graft removal with extra-anatomic repair (N = 2). Both network meta-analysis results and pooled results of multi- and single-arm cohorts indicated that partial graft removal with in situ repair has the lowest 30-day and 1-year mortality rates (0% and 6.1% respectively), followed by complete graft removal with in situ repair (11.9% and 23.8% respectively) and complete graft removal with extra-anatomic repair (16.6% and 41.4% respectively). In addition, complete graft removal with in situ repair had a lower 3-year (complete graft removal with in situ repair versus complete graft removal with extra-anatomic repair: 32.1% versus 90%) and 5-year (complete graft removal with in situ repair versus complete graft removal with extra-anatomic repair: 45.6% versus 67.9%) mortality rate when compared with complete graft removal with extra-anatomic repair. Patients in the complete graft removal with in situ repair group had the lowest reinfections (8%), followed by partial graft removal with in situ repair (9.3%) and complete graft removal with extra-anatomic repair (22.4%). Conclusion Partial graft removal with in situ repair was associated with lower 30-day and 1-year mortality rates when compared with complete graft removal with in situ repair and complete graft removal with extra-anatomic repair. Partial graft removal with in situ repair might be a feasible treatment for specific aortic graft infection patients. [ABSTRACT FROM AUTHOR]

Endothelial dysfunction is an independent risk factor for stroke. The dysfunction of endothelial cells (EC) is closely concerned with EC senescence. Gastrodin (GAS) is an organic compound extracted from the dried root mass of the Orchidaceae plant Gastrodiae gastrodiae. It is used clinically to treat diseases such as vertebrobasilar insufficiency, vestibular neuronitis and vertigo. In the present study, we used hydrogen peroxide (H2O2)‐induced human umbilical vein endothelial cells (HUVECs) to establish an in vitro EC senescence model and to investigate the role and mechanism of GAS in EC senescence. It's found that H2O2‐treated HUVECs increased the proportion of senescence‐associated β‐galactosidase (SA β‐gal) positive cells and the relative protein expression levels of senescence‐associated cyclin p16 and p21. In addition, GAS reduced the proportion of SA β‐gal positive cells and the relative protein expression levels of p16 and p21, and increased the proliferation and migration ability of HUVECs. Meanwhile, GAS increased the expression of the anti‐oxidative stress protein HO‐1 and its nuclear expression level of Nrf2. The anti‐senescence effect of GAS was blocked when HO‐1 expression was inhibited by SnPPIX. Furthermore, absence of HO‐1 abolished the effect of GAS on HUVEC proliferation and migration. In conclusion, GAS ameliorated H2O2‐induced cellular senescence and enhanced cell proliferation and migration by enhancing Nrf2/HO‐1 signalling in HUVECs. These findings of our study expanded the understanding of GAS pharmacology and suggested that GAS may offer a potential therapeutic agent for stroke. [ABSTRACT FROM AUTHOR]

With the miniaturization and integration of wearable electronics, there are some serious problems such as signal crosstalk and high power consumption that restrict its development. Active‐matrix thin‐film transistors (TFTs) with high permittivity (high‐k) insulator layer provide a promising opportunity for reducing signal crosstalk and power consumption of wearable electronics. Here, we propose a simple and cost‐effective gradient heating‐up strategy to prepare high‐k zirconium dioxide (ZrO 2)‐based dielectric films. Amorphous ZrO 2 films annealed at 400°C exhibits a high transmittance and a high dielectric properties of a relative low leakage current (10‐8 A/cm2) and large capacitance density of 215 nF/cm2. To meet requirements of flexible wearable electronics, ZrO 2‐organic polymer hybrid dielectric film was further developed. A smooth surface morphology (Sa=0.478 nm) and good dielectric performance (~10‐8 A/cm2) of ZrO 2‐based hybrid film was obtained at 250°C, which can promote the development of flexible TFT and extend the application scenarios of wearable electronics.

Wang, Haitao, Li, Mingjun, Liu, Zelin, Dai, Xiyang, Wang, Ruihua, and Shi, Lichen
- Abstract
In recent years, the unsupervised domain adaptation (UDA) technique has achieved remarkable success in cross-domain fault diagnosis of rotating machinery. In UDA, three pivotal pieces of information—namely, class labels, domain labels, and data structures, play a critical role in establishing a connection between labeled samples of the source domain and unlabeled samples of the target domain. Most research methods use only one or two of these types of information, ignoring the importance of data structure. In addition, global domain adaptive techniques are typically used, ignoring the relationships between subdomains. The conventional convolutional neural network (CNN) exhibits limited capability in extracting essential fault-related information, thereby significantly affecting the accuracy of fault identification. To address this problem, we propose the Graph Convolutional Domain Adaptive Adversarial Network (SPGCAN) as a novel approach for the intelligent diagnosis of faults in rotating machinery. A classifier and a domain discriminator are used to extract the first two types of information. Using residual networks with a multichannel split attention mechanism, graph CNNs for the modeling of data structures. We use a combination of local maximum mean discrepancy (LMMD) and adversarial domain adaptation methods to align the subdomain distributions and reduce the distributional differences between the relevant subdomains and the global. Case Western Reserve University (CWRU) bearing dataset and planetary gearbox dataset are used for cross-domain fault diagnosis and are compared with current mainstream UDA methods. Ultimately, SPGCAN demonstrates better fault identification accuracy across 24 cross-domain fault diagnosis tasks on both datasets, thus substantiating the method’s effectiveness and superiority.

Wang, Ruihua and Sun, Wenxu
- Abstract
This paper mainly investigates the finite-time rate anti-bump switching (RABS) control problem for switched systems. A novel multiple convex Lyapunov function is first proposed by constructing a convex combination of positive definite matrices for the RABS control problem of switched systems. By imposing a prespecified dwell time on state-dependent switching, a combined switching law is devised based on the new Lyapunov function to ensure that Zeno phenomenon is prevented. Then, a bumpless control scheme is proposed to reduce the big and undesired jump in the rate of system at switching instants while achieving the disturbance suppression in finite time. In the end, through an ingenious Simulink model to characterize the combined switching law and finite-time
H ∞ rate anti-bump controller, an actual engine model is used to demonstrate the validity of the proposed approach. [ABSTRACT FROM AUTHOR]- Published

- Abstract
As a major crop in the world, the sustainable development of rice is often severely restricted by bacterial blight. Breeding crops with resistance is an efficient way to control bacterial blight. However, enhancing resistance often incurs a fitness penalty, making it challenging to simultaneously increase bacterial blight resistance and yield potential. In this study, it is found that OsGRF6, besides being a high-yield gene, can significantly improve rice bacterial blight resistance. Compared with wild-type, the lesion lengths of transgenic material overexpressing OsGRF6 are significantly reduced after inoculation with Xanthomonas oryzae pv. oryzae (Xoo). Furthermore, OsGRF6 can directly bind to the promoters of OsYUCCA1 and OsWRKY82, upregulating their transcription and thereby increasing rice bacterial blight resistance and yield. Haplotypic analysis based on the promoter and genome sequence combined with evolutionary analysis revealed that OsGRF6 is mainly comprised by the OsGRF6
XI and OsGRF6GJ subtypes. The superior haplotype OsGRF6Hap4 increased its transcriptional activity and contributed to bacterial blight resistance and rice yield. Together, this study provides theoretical support for further revealing the synergistic regulatory mechanism and genetic improvement of rice high yield and bacterial blight resistance, offering a new strategy for developing disease-resistant cultivars., (© 2024 The Author(s).

- Abstract
The effective iodine-131 (I-131) half-life (EHL) plays an important role in the evaluation of radioactive iodine therapy for Graves' disease (GD) patients. It has been observed that the EHL of GD patients varies after taking lithium carbonate. The purpose of this study is to investigate whether EHL can be extended and to identify the predictive factors associated with this outcome. The clinical data of 225 GD patients were retrospectively reviewed. Patients were divided into two groups based on whether the ΔEHL was ≥ 0.5 days. EHL tested after lithium carbonate was defined as Li-EHL. In the univariate analysis, age, sex, thyrotropin receptor antibody (TRAb), thyroglobulin antibody (TgAb), thyroid peroxidase antibody (TPOAb), and baseline-EHL exhibited significant differences between the two groups (P < 0.05). Cutoff values of age and baseline-EHL to predict significant EHL extension were 40.5 years and 4.85 days, respectively, as determined by receiver operating characteristic (ROC) curve analysis. Multiple linear regression analysis further revealed that the regression equation, which included age, sex, baseline-EHL, and the FT3, free triiodothyronine (FT4)/free thyroxine(FT3) ratio, was statistically significant (P < 0.05). Li-EHL positively correlated with baseline-EHL and the FT4/FT3 ratio, but negatively correlated with age. Li-EHL was also increased in female individuals. In conclusion, age, sex, baseline-EHL and the FT4/FT3 ratio were associated with Li-EHL in GD patients.

- Abstract
Background: This study aims to identify a morphological indicator of aortic dissection (AD) based on the geometrical characteristics of the thoracic aorta., Methods: We evaluated computed tomographic angiograms of 63 samples with AD (22 with type A AD, 41 with type B AD) and 71 healthy samples. Via centerline extraction and spatial transformation, the spatial entanglement of the aorta was minimized, and the expanded 2D aortic morphology was obtained. The 2D morphology of the thoracic aorta was fit to a circle. The applicability of the fitting circle method for identifying aortic dissection was verified by multivariable logistic regression analysis., Results: Via the 3D coordinate transformation algorithm, the optimal aortic view was obtained. On this view, the geometrical characteristics of the thoracic aortas of the healthy controls were similar to a portion of a circle (sum of residuals: 3502.45 ± 2566.71, variance: 86.23 ± 56.60), while that of AD samples had poorer similarity to the circle (sum of residuals: 5404.78 ± 3891.69, variance: 129.90 ± 90.09). This difference was significant (p < 0.001). A logistic regression model showed that increased deformation of the thoracic aorta was a significant indicator of aortic dissection (odds ratio: 1.35, p = 0.034)., Conclusions: The morphology of the healthy thoracic aorta could be fit to a circle, while that of the dissected aorta had poorer similarity to the circle. The statistics of the circle are an effective indicator of aortic deformation in AD., Trial Registration: This study is registered in the Chinese Clinical Trial Registry (ChiCTR2000029219)., (© 2024.

- Abstract
Immunotherapy shows great therapeutic potential for long-term protection against tumor relapse and metastasis. Innate immune sensors, such as cyclic GMP-AMP synthase (cGAS) and stimulator of interferon genes (STING), dissolve DNA and induce type I interferon. Through activation of the cGAS/STING pathway, chemotherapy drugs and reversine (REV) may provide synergetic anti-tumor effects. Here, we prepared drug-loaded cell membrane hybrid lipid nanovesicles (LEVs) (designated LEV@DOX@REV) by fusion of cell membranes, phospholipids, doxorubicin (DOX), and REV, to realize accurate delivery to tumors and chemo-immunotherapy. The cell membranes of LEVs confer "homing" abilities. DOX can induce immunogenic cell death as a result of its specific immunomodulatory effects, which promotes the maturation of immune cells and improves the microenvironment of the immune system. REV is proven to efficiently activate cGAS/STING signaling, thereby enhancing the immune system. The antitumor efficacy of LEV@DOX@REV was evaluated in a 4T1 subcutaneous tumor xenograft model, a distant metastatic tumor model, and a liver metastatic tumor model. LEV@DOX@REV facilitated the infiltration of cytotoxic T lymphocytes within tumors, increased the secretion of proinflammatory cytokines, and modified the tumor microenvironment. In conclusion, LEV@DOX@REV displayed favorable antitumor effects and extended the survival of tumor-bearing mice. We therefore successfully developed nanoparticles capable of enhancing immune activation that have potential therapeutic applications for cancer immunotherapy., Competing Interests: Competing interests: The authors declare that they have no competing interests., (Copyright © 2024 Ruijie Qian et al.)

- Abstract
Background: The aim of the present study was to evaluate the impact of intratumoral metabolic heterogeneity and quantitative
18 F-FDG PET/CT imaging parameters in predicting patient outcomes in thymic epithelial tumors (TETs)., Methods: This retrospective study included 100 patients diagnosed with TETs who underwent pretreatment18 F-FDG PET/CT. The maximum and mean standardized uptake values (SUVmax and SUVmean), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) on PET/CT were measured. Heterogeneity index-1 (HI-1; standard deviation [SD] divided by SUVmean) and heterogeneity index-2 (HI-2; linear regression slopes of the MTV according with different SUV thresholds), were evaluated as heterogeneity indices. Associations between these parameters and patient survival outcomes were analyzed., Results: The univariate analysis showed that Masaoka stage, TNM stage, WHO classification, SUVmax, SUVmean, TLG, and HI-1 were significant prognostic factors for progression-free survival (PFS), while MTV, HI-2, age, gender, presence of myasthenia gravis, and maximum tumor diameter were not. Subsequently, multivariate analyses showed that HI-1 (p < 0.001) and TNM stage (p = 0.002) were independent prognostic factors for PFS. For the overall survival analysis, TNM stage, WHO classification, SUVmax, and HI-1 were significant prognostic factors in the univariate analysis, while TNM stage remained an independent prognostic factor in multivariate analyses (p = 0.024). The Kaplan Meier survival analyses showed worse prognoses for patients with TNM stages III and IV and HI-1 ≥ 0.16 compared to those with stages I and II and HI-1 < 0.16 (log-rank p < 0.001)., Conclusion: HI-1 and TNM stage were independent prognostic factors for progression-free survival in TETs. HI-1 generated from baseline18 F-FDG PET/CT might be promising to identify patients with poor prognosis., (© 2024 The Author(s).

- Abstract
Background: Endovenous interventions and minimally invasive procedures are effective in the management of varicose veins. However, they can cause postoperative discomfort., Objective: To evaluate the clinical efficacy of sodium aescinate (SA) in improving edema, pain, vein-specific symptoms, and quality of life in patients following endovenous laser ablation (EVLA) for varicose veins., Methods: In this single-center randomized controlled trial (RCT), patients were allocated into two groups: in Group A, 60 mg SA was administered twice daily for 20 days, and in Group B (control), no venoactive drug was prescribed. The Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification system for chronic venous disorders was used to assess the varicose veins. The circumferences of the calf and ankle were recorded for evaluating edema. The 10-point Visual Analog Scale (VAS), Venous Clinical Severity Score (VCSS), and Aberdeen Varicose Veins Questionnaire (AVVQ) were used to measure the pain intensity, overall varicose vein severity, and patient's quality of life, respectively., Results: The study included 87 patients (mean age, 59.9 ± 10.7 years; 54 men) with CEAP class C2-C5 varicose veins who underwent EVLA and phlebectomy or foam sclerotherapy. The calf circumference recovered quicker in Group A than in Group B by days 10, 21, and 30 (difference from baseline was 1.04 ± 0.35 vs 2.39 ± 1.15 [ p < .001], 0.48 ± 0.42 vs1.73 ± 1.00 [ p < .001], and 0.18 ± 0.64 vs 0.82 ± 0.96 [ p < .001], respectively). The ankle circumference recovered quicker in Group A than in Group B by days 10 and 21 (the difference from baseline was 1.37 ± 0.52 vs 2.36 ± 0.93 [ p < .001] and 0.58 ± 0.60 vs 1.14 ± 0.88 [ p = .002], respectively). Pain relief was achieved quicker in Group A than in Group B (0.257 ± 1.097 [ p = .0863] vs 0.506 ± 1.250 [ p = .0168] by day 21). There were no significant differences in the VCSS and AVVQ scores between both groups. There were no drug-related adverse effects., Conclusions: SA, in combination with compression therapy, can relieve edema and alleviate pain in patients following EVLA for varicose veins., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Anticoagulation therapy stands as a key treatment for thrombotic diseases. The consequential bleeding risk tied to existing anticoagulation methods significantly impacts patient prognosis. In the intensive care unit (ICU), patients often necessitate organ support, leading to the inevitable placement of artificial devices in blood vessels, thereby requiring anticoagulation treatment to avert clot formation that might impede organ support. Nevertheless, these patients commonly encounter a heightened risk of bleeding. Hemophilia B, identified in 1953, manifests as a deficiency in coagulation factor XI (FXI), which focused people's perspective on the endogenous coagulation pathway, that is, the contact pathway. Upon interaction between the surface of artificial devices and FXII, FXII activates, subsequently triggering FXI and initiating the "coagulation cascade" within the contact pathway. Inhibitors targeting the contact pathway encompass two primary categories: FXII inhibitors and FXI inhibitors, capable of impeding this process. This article reviews the role of FXII and FXI in activating the contact pathway, seeking to illuminate their contributions to thrombus formation. By listing the relatively mature drugs and their indications, clinicians are familiar with this new anticoagulant.

- Abstract
Background: To investigate the roles of extracellular vesicles (EVs) secreted from bone marrow mesenchymal stem cells (BMSCs) and miR-27 (highly expressed in BMSC EVs) in hepatic ischemia‒ reperfusion injury (HIRI)., Approaches and Results: We constructed a HIRI mouse model and pretreated it with an injection of agomir- miR-27-3p , agomir-NC, BMSC-EVs or control normal PBS into the abdominal cavity. Compared with the HIRI group, HIRI mice preinjected with BMSC-EVs had significantly decreased alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels and alleviated liver necrosis (P<0.05). However, compared with HIRI+NC mice, HIRI+ miR-27b mice had significantly increased ALT and AST levels, aggravated liver necrosis, and increased apoptosis-related protein expression (P<0.05). The proliferation and apoptosis of AML-12 cells transfected with miR-27 were significantly higher than the proliferation and apoptosis of AML-12 cells in the mimic NC group (P<0.01) after hypoxia induction. SMAD4 was proven to be a miR-27 target gene. Furthermore, compared to HIRI+NC mice, HIRI+ miR-27 mice displayed extremely reduced SMAD4 expression and increased levels of wnt1, β-catenin, c-Myc, and Cyclin D1., Conclusion: Our findings reveal the role and mechanism of miR-27 in HIRI and provide novel insights for the prevention and treatment of HIRI; for example, EVs derived from BMSCs transfected with antimiR- 27 might demonstrate better protection against HIRI., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
