FedSTS: A Stratified Client Selection Framework for Consistently Fast Federated Learning.

In this article, we investigate random client selection in the context of horizontal federated learning (FL), whereby only a randomly selected subset of clients transmit their model updates to the server instead of yielding all clients involved. Many researchers have demonstrated that clustering-based client selection constitutes a simple yet efficacious approach to the identification of those clients possessing representative gradient information. Despite the extensive body of research on modified selection methodologies, the majority of prior work is predicated upon the assumption of consistently effective clustering.

Learning to Summarize Chinese Radiology Findings With a Pre-Trained Encoder.

Automatic radiology report summarization has been an attractive research problem towards computer-aided diagnosis to alleviate physicians' workload in recent years. However, existing methods for English radiology report summarization using deep learning techniques cannot be directly applied to Chinese radiology reports due to limitations of the related corpus. In response to this, we propose an abstractive summarization approach for Chinese chest radiology report.

BPTF activates the MAPK pathway through coexpression with Raf1 to promote proliferation of T-cell lymphoma.

The aim of the present study was to explore the role and biological function of bromodomain PHD finger transcription factor (BPTF) in T-cell lymphoma. Reverse transcription-quantitative PCR (RT-qPCR), western blotting, immunohistochemistry and bioinformatics analysis were used to determine the expression levels of BPTF and Raf1 in T-cell lymphoma tissues and matched adjacent normal tissues. RT-qPCR and western blot analyses were used to examine the role of BPTF in the activation of MAPK signaling.

Simvastatin potentiates the cell-killing activity of imatinib in imatinib-resistant chronic myeloid leukemia cells mainly through PI3K/AKT pathway attenuation and Myc downregulation.

Constitutively activated BCR-ABL kinase is considered the driver event responsible in the initiation and development of chronic myeloid leukemia (CML). The advent of the first BCR-ABL inhibitor imatinib has significantly improved the clinical outcome of CML cases. However, resistance to imatinib occurs in 25-30% of CML patients.

The efficacy and safety of multiple versus single doses dexamethasone in unicompartmental knee arthroplasty: A protocol of randomized controlled trial.

Background: Concerns exist regarding the analgesia effect and safety of multiple versus single doses dexamethasone in unicompartmental knee arthroplasty. There is an urgent need of studies that efficiently control for confounding, conduct comprehensive and consecutive observation of potential risks of the dexamethasone administration, and investigate its clinical applicability. We thus further designed a randomized controlled study to assess the different dose of dexamethasone on postoperative pain and complications in patients undergoing unicompartmental knee arthroplasty.

Analysis of 4 imaging features in patients with COVID-19.

Background: The aim of this was to analyze 4 chest CT imaging features of patients with coronavirus disease 2019 (COVID-19) in Shenzhen, China so as to improve the diagnosis of COVID-19.

Methods: Chest CT of 34 patients with COVID-19 confirmed by the nucleic acid test (NAT) were retrospectively analyzed. Analyses were performed to investigate the pathological basis of four imaging features("feather sign","dandelion sign","pomegranate sign", and "rime sign") and to summarize the follow-up results.

Isobavachalcone attenuates Sephadex-induced lung injury via activation of A20 and NRF2/HO-1 in rats.

The aim of this study is to investigate the protective effect and underlying molecular mechanisms of isobavachalcone on Sephadex-induced lung injury in rats. The result showed isobavachalcone inhibited massive granulomas, decreased inflammatory cells infiltration and oxidative stress markers level, but it can increase antioxidant enzymes level. The ELISA assay exhibited isobavachalcone decreased TNF-α production in BALF and lung tissue.

Altered Gray Matter Volume in Stable Chronic Obstructive Pulmonary Disease with Subclinical Cognitive Impairment: an Exploratory Study.

Gray matter volume deficits have been identified in cognitively impaired patients with chronic obstructive pulmonary disease (COPD). However, it remains unknown whether the gray matter volume is altered in COPD patients with subclinical cognitive impairment. To determine whether any gray matter abnormalities are present in these patients, neuropsychological tests and structural MRI data were analyzed from 60 patients with COPD and 60 age-, gender-, education-, and handedness-matched normal controls (NCs).

Rheum palmatum L. Attenuates High Fat Diet-Induced Hepatosteatosis by Activating AMP-Activated Protein Kinase.

Nonalcoholic fatty liver disease (NAFLD) is a common metabolic disorder characterized by the accumulation of excess fat in the liver. Rheum palmatumL. (RP) decoctions have been reported to ameliorate NAFLD.

Puerarin suppresses high glucose-induced MCP-1 expression via modulating histone methylation in cultured endothelial cells.

Aims: Hyperglycemia is commonly associated with microcirculation dysfunction. The purpose of the present study was to investigate the epigenetic mechanism involved in the repression of monocyte chemoattractant protein-1 (MCP-1) expression by puerarin under high glucose (25mM) condition.

Main Methods: MCP-1 gene expression was measured by Real-Time quantitative Polymerase Chain Reaction (RT-qPCR), the histone 3 lysine 4 methylation (H3K4me) and lysine 9 methylation (H3K9me) were evaluated using chromatin immunoprecipitation assay.

[CT angiography features of the involved arterial branches of the spontaneous isolated superior mesenteric artery dissection].

Objective: To explore the CT angiography features of the involved arterial branches of the spontaneous isolated superior mesentery artery dissection(SISMAD).

Methods: Clinical and CT angiogram data of 6 patients with SISMAD confirmed by dual source energy CT angiography were analyzed retrospectively. The CT angiography features and prognosis of patients were investigated.

Characterization, pharmacokinetics, and hypoglycemic effect of berberine loaded solid lipid nanoparticles.

The high aqueous solubility, poor permeability, and absorption of berberine (BBR) result in its low plasma level after oral administration, which greatly limits its clinical application. BBR solid lipid nanoparticles (SLNs) were prepared to achieve improved bioavailability and prolonged effect. Developed SLNs showed homogeneous spherical shapes, small size (76.

Meta-analysis of acupuncture for relieving non-organic dyspeptic symptoms suggestive of diabetic gastroparesis.

Background: Acupuncture is widely used to treat diabetic patients with dyspeptic symptoms suggestive of gastroparesis in China. We conducted this systematic review of randomized controlled trials (RCTs) to evaluate the efficacy of acupuncture for diabetic gastroparesis (DGP).

Methods: We searched PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL) and four Chinese databases including China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals, Chinese Biomedical Literature Database (CBM) and WanFang Data up to January 2013 without language restriction.

An Aqueous Extract of Radix Astragali, Angelica sinensis, and Panax notoginseng Is Effective in Preventing Diabetic Retinopathy.

Diabetic retinopathy (DR), in which inflammation has been implicated playing important roles, is one of the most common diabetes complications. Dang Gui Bu Xue Tang (DBT), an aqueous extract of Radix Astragali and Radix Angelica sinensis, is a classical prescription in Traditional Chinese Medicine for treating inflammation and ischemic diseases. Here, we investigated the effects of a modified recipe of DBT, with addition of Panax notoginseng, in treating diabetic retinopathy.

The molecular cloning of glial fibrillary acidic protein in Gekko japonicus and its expression changes after spinal cord transection.

The glial fibrillary acidic protein (GFAP) is an astrocyte-specific member of the class III intermediate filament proteins. It is generally used as a specific marker of astrocytes in the central nervous system (CNS). We isolated a GFAP cDNA from the brain and spinal cord cDNA library of Gekko japonicus, and prepared polyclonal antibodies against gecko GFAP to provide useful tools for further immunochemistry studies.
