Multidimensional Refinement Graph Convolutional Network With Robust Decouple Loss for Fine-Grained Skeleton-Based Action Recognition.

Graph convolutional networks (GCNs) have been widely used in skeleton-based action recognition. However, existing approaches are limited in fine-grained action recognition due to the similarity of interclass data. Moreover, the noisy data from pose extraction increase the challenge of fine-grained recognition.

Factoring and correlation in sleep, fatigue and mental workload of clinical first-line nurses in the post-pandemic era of COVID-19: A multi-center cross-sectional study.

Background: A better understanding of the factors and their correlation with clinical first-line nurses' sleep, fatigue and mental workload is of great significance to personnel scheduling strategies and rapid responses to anti-pandemic tasks in the post-COVID-19 pandemic era.

Objective: This multicenter and cross-sectional study aimed to investigate the nurses' sleep, fatigue and mental workload and contributing factors to each, and to determine the correlation among them.

Methods: A total of 1,004 eligible nurses (46 males, 958 females) from three tertiary hospitals participated in this cluster sampling survey.

High brightness silicon nanocrystal white light-emitting diode with luminance of 2060 cd/m.

High brightness Si nanocrystal white light-emitting diodes (WLED) based on differentially passivated silicon nanocrystals (SiNCs) are reported. The active layer was made by mixing freestanding SiNCs with hydrogen silsesquioxane, followed by annealing at moderately high temperatures, which finally led to a continuous spectral light emission covering red, green and blue regimes. The photoluminescence quantum yield (PLQY) of the active layer was 11.

Identifying critically ill patients at risk of death from coronavirus disease.

Background: A pandemic of coronavirus disease (COVID-19) has been declared by the World Health Organization (WHO) and caring for critically ill patients is expected to be at the core of battling this disease. However, little is known regarding an early detection of patients at high risk of fatality.

Methods: This retrospective cohort study recruited consecutive adult patients admitted between February 8 and February 29, 2020, to the three intensive care units (ICUs) in a designated hospital for treating COVID-19 in Wuhan.

Genome-wide identification, evolution of DNA methyltransferases and their expression during gonadal development in Nile tilapia.

DNA methyltransferases (dnmts) are responsible for DNA methylation and play important roles in organism development. In this study, seven dnmts genes (dnmt1, dnmt2, dnmt3aa, dnmt3ab, dnmt3ba, dnmt3bb.1, dnmt3bb.

Circulating osteogenic endothelial progenitor cell counts: new biomarker for the severity of coronary artery disease.

Background: There is increasing evidence implying that the early and functionally highly active circulating endothelial progenitor cell (CEPC) phenotype (CD34-/CD133+/KDR+) with osteogenic potential (OCN+) might link between vascular atherosclerotic calcification and mechanisms of bone metabolism. We sought to evaluate the early OCN+ CEPC counts as an independent biomarker for the severity of coronary artery disease (CAD).

Methods: Peripheral blood samples were drawn from 593 patients undergoing clinically indicated coronary angiography.

Comparison of Therapeutic Effect of Recombinant Tissue Plasminogen Activator by Treatment Time after Onset of Acute Ischemic Stroke.

We aimed to compare the therapeutic effect of recombinant tissue plasminogen activator (rt-PA) administered at different time windows within the first 6 hours after onset of acute ischemic stroke (AIS). A retrospective analysis was performed of data collected from 194 patients who received rt-PA thrombolysis within 4.5 hours after AIS onset and from 29 patients who received rt-PA thrombolysis between 4.

Increased plasma BMP-2 levels are associated with atherosclerosis burden and coronary calcification in type 2 diabetic patients.

Background: Although Bone morphogenetic protein-2 (BMP-2) is a known mediator of bone regeneration and vascular calcification, to date no study has investigated the relationship between BMP-2 and type 2 diabetes mellitus (T2DM) and its possible role in coronary artery disease (CAD). The purpose of this study is to evaluate the relationship of BMP-2 with atherosclerosis and calcification in patients with T2DM.

Methods: 124 subjects were enrolled in this study: 29 patients with T2DM and CAD; 26 patients with T2DM and without CAD; 36 patients with CAD and without T2DMand 34 without T2DM or CAD (control group).

Plasma levels of tissue inhibitor of matrix metalloproteinase-1 correlate with diagnosis and prognosis of glioma patients.

Background: There is no validated blood biomarker available for glioma management. Invasive growth is the key feature of glioma. We assessed the clinical usefulness of plasma tissue inhibitor of metalloproteinase 1 (TIMP-1), which has less molecular weight than metalloproteinases, as a potential blood biomarker for glioma.

Salvianolate inhibits reactive oxygen species production in H(2)O(2)-treated mouse cardiomyocytes in vitro via the TGFβ pathway.

Aim: To investigate the effects of salvianolate, a water-soluble active compound from Salvia miltiorrhiza Bunge, on reactive oxygen species (ROS) production in mouse cardiomyocytes in vitro.

Methods: Primary ventricular cardiomyocytes were prepared from neonatal mouse. The cell viability was determined using MTT assay.

Anti-CHMP5 single chain variable fragment antibody retrovirus infection induces programmed cell death of AML leukemic cells in vitro.

Aim: Over-expressed CHMP5 was found to act as oncogene that probably participated in leukemogenesis. In this study, we constructed the CHMP5 single chain variable fragment antibody (CHMP5-scFv) retrovirus and studied the changes of programmed cell death (PCD) of AML leukemic cells after infection by the retrovirus.

Methods: The anti-CHMP5 KC14 hybridoma cell line was constructed to generate monoclonal antibody of CHMP5.

Central venous access sites for the prevention of venous thrombosis, stenosis and infection.

Background: Central venous access (CVA) is widely used. However, its thrombotic, stenotic and infectious complications can be life-threatening and involve high-cost therapy. Research revealed that the risk of catheter-related complications varied according to the site of CVA.

[Delayed operation on treatment of high-energy distal tibia Pilon fracture].

Objective: To investigate the selection of operative methods,timing of operation and the effect of hige-energy distal tibia Pilon fracture.

Methods: From July 2006 to December 2009, 29 patients with hige-energy distal tibia Pilon fractures were treated, including 23 males and 6 females with an average age of 36.8 years old ranging from 21 to 54 years.
