To investigate the blood coagulation function in COVID-19 patients, and the correlation between coagulopathy and disease severity. We retrospectively collected 147 clinically diagnosed COVID-19 patients at Wuhan Leishenshan Hospital of Hubei, China. We analyzed the coagulation function in COVID-19 patients through the data including thrombin-antithrombin complex (TAT), α2-plasmininhibitor-plasmin Complex (PIC), thrombomodulin (TM), t-PA/PAI-1 Complex (t-PAIC), prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (FIB), thrombin time (TT), D-Dimer (DD), and platelet (PLT). The levels of TAT, PIC, TM, t-PAIC, PT, INR, FIB, and DD in COVID-19 patients were higher than health controls (p<0.05), and also higher in the patients with thrombotic disease than without thrombotic disease (p<0.05). What's more, the patients with thrombotic disease had a higher case-fatality (p<0.05). TAT, PIC, TM, t-PAIC, PT, INR, APTT, FIB, DD, and PLT were also found correlated with disease severity. Meanwhile, we found that there were significant difference in TAT, TM, t-PAIC, PT, INR, APTT, DD, and PLT in the death and survival group. Further using univariate and multivariate logistic regression analysis also found that t-PAIC and DD were independent risk factors for death in patients and are excellent predicting the mortality risk of COVID-19. Most COVID-19 patients with inordinate coagulation systems, dynamic monitoring of coagulation parameters might be a key in the control of COVID-19 death.

Eye movements are one of the most fundamental behaviors during reading. A growing number of Chinese reading studies have used eye-tracking techniques in the last two decades. The accumulated data provide a rich resource that can reflect the complex cognitive mechanisms underlying Chinese reading. This article reports a database of eye-movement measures of words during Chinese sentence reading. The database contains nine eye-movement measures of 8,551 Chinese words obtained from 1,718 participants across 57 Chinese sentence reading experiments. All data were collected in the same experimental environment and from homogenous participants, using the same protocols and parameters. This database enables researchers to test their theoretical or computational hypotheses concerning Chinese reading efficiently using a large number of words. The database can also indicate the processing difficulty of Chinese words during text reading, thus providing a way to control or manipulate the difficulty level of Chinese texts.Measurement(s)eye movementTechnology Type(s)eye trackingFactor Type(s)word frequency • word lengthSample Characteristic - OrganismHumanSample Characteristic - Environmentlaboratory environment

Given the lack of spaces between words in Chinese text, Chinese readers must parse these characters into words using their word knowledge. In this situation, are the characters belonging to a single word or to different words understood via different character-order encoding processes? In this study, we explored the effects of word boundaries in Chinese text on character-order encoding. We used four-character words (the one-word condition) and two two-character words (the two-word condition) as our targets. We embedded the target words into sentences and then manipulated the previews of the words using the boundary paradigm. The preview was identical to the target word (identity condition), had the two middle characters of the target word transposed (TC condition), or had two middle characters that were different from those in the target word (SC condition). Fixation durations on the target word in the TC condition were much longer than those in the identity condition for the two-word condition, but they were not significantly different for the one-word condition. Furthermore, for the one-word condition, gaze durations were longer in the SC than in the TC condition, whereas for the two-word condition, the difference between the TC and SC conditions was not significant. Word boundaries were found to affect the character-order encoding in Chinese reading, further suggesting the early occurrence of word segmentation.

As a comprehensive utilization of pipeline resources, communication intelligent manhole cover (CIMC) can effectively real-time monitor communication manhole cover and protect the safety of communication pipeline. Due to the complex working environment of manhole cover and the random error of sensor, the traditional monitoring method usual leads to frequent false alarm in actual applications. In order to ensure the monitoring service quality and improve the service efficiency, a new alarm method of CIMC with multiple event fusion in this paper via jointing analysis of multi-sensor status signals is proposed based on the equipment status signals generated by the CIMC terminal and abnormal alarm events definition. The experimental result shows that the proposed CIMC alarm method by means of multiple sensor signals in this paper can not only make up for the defect of a single sensor, but also reduces the false alarm rate caused by the random error of sensor and CIMC system. It can promote the intelligent monitoring efficiency of the manhole cover and be conducive to the construction of intelligent transportation and smart city.

Mesenchymal stem cell (MSC) holds immense potential as candidates for cell therapy in the treatment of tendon injuries due to their remarkable ability for multiple cell differentiation. However, the proliferative and differentiation capacity of MSCs has been limited by cellular senescence during the process of expanding culture. Therefore, in this study, our aim was to maintain the beneficial properties of MSCs. We found that SETD7, a histone methyltransferase, was upregulated during ex vivo expansion of human adipose-derived mesenchymal stem cells (hAD-MSCs). Pharmacological inhibition of SETD7 with PFI-2 in hAD-MSCs cultures delayed their senescence, as evident by the diminished expression of senescent-associated genes and the maintenance of their proliferation and differentiation capacity. Upon transplantation, cell sheets derived from hAD-MSCs expanded with PFI-2 were better able to accelerate tendon repair. Therefore, the present findings reveal that SETD7 is an important target to improve the expansion of hAD-MSCs by delaying senescence, which is importance for the development of efficient stem cell-based therapeutic approaches.

Background To the best of our knowledge, although the Chinese version of the Yale Global Tic Severity Scale (YGTSS) is widely used in child psychiatry departments in China, there is very little evidence focusing on the psychometric characteristics of the Chinese version of YGTSS. In this present study, we aim to re-examine the structure of the Chinese version of YGTSS and investigate its reliability and validity. Methods A total of 367 children and adolescents with tic disorders aged 5–16 years old participated in the study. The Cronbach’s alpha, test-retest reliability and concurrent validity will be calculated. Confirmatory Factor Analysis (CFA) also will be performed to assess the structure of YGTSS. Results The Cronbach’s alpha of the motor tic subscale of YGTSS was 0.84, for the phonic tic subscale of YGTSS, it was 0.90, but for the whole scale, it was 0.58. The test-retest reliability of YGTSS was 0.84. For the results of CFA, the Comparative Fit Index (CFI) of YGTSS based on the Two-Factor Model and Three-Factor Model was 0.97 and 0.96 respectively. The measurement invariance analysis suggested that the Two-Factor model of YGTSS across different age and sex groups was at the accepted level (≥0.90). Conclusion Overall, according to the results of this research, it suggested that the Chinese version of YGTSS showed good psychometric properties. It can be used in the assessment of tic disorders in the Chinese population. In the future, more comprehensive tools for assessing tics need to be further developed, which can cover the symptoms of premonitory urge and tic related obsessive-compulsive symptoms.

Type 1 allergies, involve a complex interaction between dendritic cells and other immune cells, are pathological type 2 inflammatory immune responses against harmless allergens. Activated dendritic cells undergo extensive phenotypic and functional changes to exert their functions. The activation, differentiation, proliferation, migration, and mounting of effector reactions require metabolic reprogramming. Dendritic cells are important upstream mediators of allergic responses and are therefore an important effector of allergies. Hence, a better understanding of the underlying metabolic mechanisms of functional changes that promote allergic responses of dendritic cells could improve the prevention and treatment of allergies. Metabolic changes related to dendritic cell activation have been extensively studied. This review briefly outlines the basis of fatty acid oxidation and its association with dendritic cell immune responses. The relationship between immune metabolism and effector function of dendritic cells related to allergic diseases can better explain the induction and maintenance of allergic responses. Further investigations are warranted to improve our understanding of disease pathology and enable new treatment strategies.

The tendon-bone interface effectively transfers mechanical stress for movement, yet its regeneration presents significant clinical challenges due to its hierarchical structure and composition. Biomimetic strategies that replicate the distinctive characteristics have demonstrated potential for enhancing the healing process. However, there remains a challenge in developing a composite that replicates the nanostructure of the tendon-bone interface and embeds living cells. Here, we engineered a nanoscale biomimetic bilayer hydrogel embedded with tendon stem cells for tendon-bone interface healing. Specifically, the biomimetic hydrogel incorporates intra- and extrafibrillar mineralized collagen fibrils as well as non-mineralized collagen fibrils resembling the tendon-bone interface at the nanoscale. Furthermore, biomimetic mineralization with the presence of cells realizes living tendon-bone-like tissue constructs. In the in vivo patella-patellar tendon-interface injury model, the tendon stem cell-laden biomimetic hydrogel promoted tendon-bone interface regeneration, demonstrated by increased fibrocartilage formation, improved motor function, and enhanced biomechanical outcomes. This study highlights the potential of the stem cell-laden biomimetic hydrogel as an effective strategy for tendon-bone interface regeneration, offering a novel approach to engineering complex tissue interfaces.
