Exploration of evaluation criteria based on the biological variation in the external quality assessment for basic semen analysis in China.

This study explores whether the current external quality assessment (EQA) level and acceptable bias for basic semen analysis in China are clinically useful. We collected data of semen EQA from Andrology laboratories in the Hunan Province (China) in 2022 and searched for data in the published literature from January 2000 to December 2023 in China. On the basis of these data, we analyzed the coefficients of variation and acceptable biases of different quality control materials for basic semen analysis through robust statistics.

Clinical Outcome of UCBT for Children with CAEBV: A Retrospective Analysis of a Single Center.

Background: Chronic active Epstein-Barr virus (CAEBV) infection is a severe, life-threatening condition characterized by persistent Epstein-Barr virus (EBV) infection and the clonal expansion of infected T or NK cells, leading to systemic inflammation, organ damage, and complications such as hemophagocytic lymphohistiocytosis and lymphoma. Allogeneic hematopoietic stem cell transplantation (HSCT) is the only effective treatment for eradicating EBV-infected cells; however, donor availability is limited. Umbilical cord blood stem cell transplantation (UCBT) is a promising alternative owing to its rapid availability and lower complication risk.

Spatiotemporal transcriptomics elucidates the pathogenesis of fulminant viral myocarditis.

Fulminant myocarditis (FM) is a severe inflammatory condition of the myocardium that often results in sudden death, particularly in young individuals. In this study, we employed single-nucleus and spatial transcriptomics to perform a comprehensive analysis of coxsackievirus B3 (CVB3)-induced FM in A/J mice, spanning seven distinct time points pre- and post-treatment. Our findings reveal that mesothelial cells play a critical role in the early stage of myocarditis by acting as primary targets for CVB3 infection.

ABCA1-Super Enhancer RNA Promotes Cholesterol Efflux, Reduces Macrophage-Mediated Inflammation and Atherosclerosis.

We describe a previously uncharacterized ATP-binding cassette A1 super enhancer RNA (ABCA1-seRNA)-mediated cholesterol efflux. In addition, it promoted macrophage inflammatory cytokine release, and was causally correlated with coronary artery disease severity. Mechanistically, ABCA1-seRNA upregulated cholesterol efflux by interacting with mediator complex subunit 23 and recruiting retinoid X receptor-alpha and liver X receptor-alpha to promote ABCA1 transcription in a manner.

Methods: Adults aged 20-59 years from Shanghai, China, were included.

Clinical characteristics and risk factors for in-hospital mortality of COVID-19 patients in Hubei Province: A multicenter retrospective study.

Background: Coronavirus disease (COVID-19) remains one of the most significant factors threatening public health security worldwide. The COVID-19 pandemic has been ongoing for more than 3 years; however, there are few studies on the clinical characteristics and mortality risk factors in patients with COVID-19 based on comprehensive data from multiple centers.

Methods: A total of 53,030 patients with confirmed COVID-19 from 138 hospitals in Hubei Province were included in this study.

Subcellular mass spectrometric detection unveils hyperglycemic memory in the diabetic heart.

Background: Intensive glycemic control is insufficient to reduce the risk of heart failure in patients with diabetes mellitus. While the hyperglycemic memory in the diabetic cardiomyopathy has been well documented, its underlying mechanisms are not fully understood. The present study tried to investigate whether the dysregulated proteins/biological pathways, which persistently altered in diabetic hearts during normoglycemia, participate in the hyperglycemic memory.

Nafamostat mesylate sensitizes ovarian cancer cells to carboplatin by promoting the ZNF24-mediated inhibition of WNT2B.

Resistance to chemotherapeutic medicines complicates and eventually kills people with ovarian cancer. Nafamostat mesylate (NM) has been used as an adjuvant therapy to enhance chemotherapy sensitivity in several cancers. This study aimed to evaluate the effect of NM on ovarian cancer cells susceptible to carboplatin (CBP) and to determine the underlying mechanism involved.

Immunoglobin attenuates fulminant myocarditis by inhibiting overactivated innate immune response.

Background And Purpose: Fulminant myocarditis (FM) is a myocardial inflammatory disease that can result from either viral diseases or autoimmune diseases. In this study, we have determined the treatment effects of immunomodulatory drugs on FM.

Experimental Approach: FM was induced in A/JGpt mice by intraperitoneal administration of coxsackievirus B3, after which immunoglobins were administered daily by intraperitoneal injection.

Carnitine is a friend in HFpEF and foe in HFrEF.

Heart failure (HF) is a global concern, particularly HF with preserved ejection fraction (HFpEF), lacking effective treatments. Understanding the differences of metabolic profiles between HFpEF and HFrEF (heart failure with reduced ejection fraction) patients is crucial for therapeutic advancements. In this study, pseudotargeted metabolomics was employed to analyze for disparities of plasma metabolic profiles between HFpEF and HFrEF in two cohorts: discovery ( = 514) and validation ( = 3368).

Insights into the post-translational modifications in heart failure.

Heart failure (HF), as the terminal manifestation of multiple cardiovascular diseases, causes a huge socioeconomic burden worldwide. Despite the advances in drugs and medical-assisted devices, the prognosis of HF remains poor. HF is well-accepted as a myriad of subcellular dys-synchrony related to detrimental structural and functional remodelling of cardiac components, including cardiomyocytes, fibroblasts, endothelial cells and macrophages.

Regulatory effect of rapamycin on recruitment and function of myeloid-derived suppressor cells in heart failure.

Background: Immune response and inflammation play important roles in the physiological and pathophysiological processes of heart failure (HF). In our previous study, myeloid-derived suppressor cells (MDSCs), a heterogeneous group of immature myeloid cells with anti-inflammatory and immunosuppressive functions, were shown to exert cardioprotective effects in HF. The pharmacological targeting of MDSCs using rapamycin may emerge as a promising strategy for the prevention and treatment of HF.
