Clinical knowledge-based ECG abnormalities detection using dual-view CNN-Transformer and external attention mechanism.

Background: Automatic abnormalities detection based on Electrocardiogram (ECG) contributes greatly to early prevention, computer aided diagnosis, and dynamic analysis of cardiovascular diseases. In order to achieve cardiologist-level performance, deep neural networks have been widely utilized to extract abstract feature representations. However, the mechanical stacking of numerous computationally intensive operations makes traditional deep neural networks suffer from inadequate learning, poor interpretability, and high complexity.

Supermolecules as a quality markers of herbal medicinal products.

Herbal medicines have greatly contributed to human health worldwide for thousands of years. In particular, traditional Chinese medicine plays an essential role in the prevention and treatment of COVID-19. With the exponentially increasing use and global attention to herbal medicinal products (HMPs), efficacy and safety have become major public concerns in many countries.

Berberine Suppresses Mice Depression Behaviors and Promotes Hippocampal Neurons Growth Through Regulating the miR-34b-5p/miR-470-5p/BDNF Axis.

Background: Berberine has been found to inhibit the progression of depression disorder, but its specific mechanism is still unclear. MicroRNA (miRNA) is considered to play an important role in the progression of depression. However, it is unclear whether Berberine is involved in the regulation of depression progression through miRNA.

The physical microenvironment of hematopoietic stem cells and its emerging roles in engineering applications.

Stem cells are considered the fundamental underpinnings of tissue biology. The stem cell microenvironment provides factors and elements that play significant roles in controlling the cell fate direction. The bone marrow is an important environment for functional hematopoietic stem cells in adults.

Quantitative and Qualitative Analyses of Psychological Experience and Adjustment of In Vitro Fertilization-Embryo Transfer Patients.

BACKGROUND The aim of this study was to quantitatively analyze the psychosocial characteristics of in vitro fertilization-embryo transfer (IVF-ET) couples and normal couples, and to identify the influencing factors of psychological characteristics and pregnancy outcomes. MATERIAL AND METHODS There were 260 infertile couples undergoing IVF-ET and 277 healthy couples of childbearing age in Shengjing Hospital of China Medical University recruited into 2 groups. Psychosocial characteristics were compared to analyze the influencing factors of pregnancy outcomes after IVF-ET.

Potential link between genetic polymorphisms of and dopamine receptors and treatment efficacy of risperidone on schizophrenia.

Objective: The current study aimed to explore the association of single nucleotide polymorphisms (SNPs) within () and dopamine receptors with schizophrenia and genetic association with risperidone treatment response.

Methods: A total of 690 schizophrenic patients (case group) were selected and 430 healthy people were included as the controls. All patients received risperidone treatment continuously for 8 weeks.

Potassium Supplementation Prevents Sodium Chloride Cotransporter Stimulation During Angiotensin II Hypertension.

Angiotensin II (AngII) hypertension increases distal tubule Na-Cl cotransporter (NCC) abundance and phosphorylation (NCCp), as well as epithelial Na(+) channel abundance and activating cleavage. Acutely raising plasma [K(+)] by infusion or ingestion provokes a rapid decrease in NCCp that drives a compensatory kaliuresis. The first aim tested whether acutely raising plasma [K(+)] with a single 3-hour 2% potassium meal would lower NCCp in Sprague-Dawley rats after 14 days of AngII (400 ng/kg per minute).

A peer victimisation scale based on a behavioural consequences measurement strategy.

Introduction: An accurate assessment of peer victimisation (i.e. bullying) is a necessary precondition for research and intervention.

Short-term nonpressor angiotensin II infusion stimulates sodium transporters in proximal tubule and distal nephron.

In Sprague Dawley rats, 2-week angiotensin II (AngII) infusion increases Na(+) transporter abundance and activation from cortical thick ascending loop of Henle (TALH) to medullary collecting duct (CD) and raises blood pressure associated with a pressure natriuresis, accompanied by depressed Na(+) transporter abundance and activation from proximal tubule (PT) through medullary TALH. This study tests the hypothesis that early during AngII infusion, before blood pressure raises, Na(+) transporters' abundance and activation increase all along the nephron. Male Sprague Dawley rats were infused via osmotic minipumps with a subpressor dose of AngII (200 ng/kg/min) or vehicle for 3 days.

Salt Sensitivity in Response to Renal Injury Requires Renal Angiotensin-Converting Enzyme.

Recent evidence indicates that salt-sensitive hypertension can result from a subclinical injury that impairs the kidneys' capacity to properly respond to a high-salt diet. However, how this occurs is not well understood. Here, we showed that although previously salt-resistant wild-type mice became salt sensitive after the induction of renal injury with the nitric oxide synthase inhibitor Nω-nitro-l-arginine methyl ester hydrochloride; mice lacking renal angiotensin-converting enzyme, exposed to the same insult, did not become hypertensive when faced with a sodium load.

D-cycloserine augmentation in behavioral therapy for obsessive-compulsive disorder: a meta-analysis.

Objective: To evaluate the overall effect of D-cycloserine (DCS) augmentation on exposure and response prevention (ERP) therapy for obsessive-compulsive disorder (OCD).

Methods: Clinical studies on the effect of DCS augmentation on ERP therapy for OCD compared to placebo were included for meta analysis. The primary outcome was the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).

Clinical predictors of familial depression in Han Chinese women.

Background: A number of clinical features potentially reflect an individual's familial vulnerability to major depression (MD), including early age at onset, recurrence, impairment, episode duration, and the number and pattern of depressive symptoms. However, these results are drawn from studies that have exclusively examined individuals from a European ethnic background. We investigated which clinical features of depressive illness index familial vulnerability in Han Chinese females with MD.
