[Explanation and interpretation of the compilation of neonatal blood transfusion in the national health standard "Guideline for pediatric transfusion"].

In order to guide clinical blood transfusion practices for pediatric patients, the National Health Commission has released the health standard "Guideline for pediatric transfusion" (WS/T 795-2022). Considering the physiological particularities of the neonatal period, blood transfusion practices for neonates are more complex than those for other children, the guidelines include a separate chapter dedicated to neonatal blood transfusion. This paper interprets the background and evidence for the compilation of the neonatal blood transfusion provisions, hoping to aid in the understanding and implementation of the neonatal blood transfusion section of the guidelines.

Untargeted screening and differential analysis of bioactive compounds in male and female silkworm (Bombyx mori) pupae through Orbitrap Exploris mass spectrometry.

Silkworm pupae are highly valuable as edible insects due to their nutritional and bioactive properties. Investigating the bioactive compounds within silkworm pupae can provide useful information for advanced processing and utilization of this resource. In this study, untargeted metabolomics analysis was employed to characterize the bioactive compounds present in silkworm pupae (Bombyx mori).

CARM1-mediated OGT arginine methylation promotes non-small cell lung cancer glycolysis by stabilizing OGT.

O-GlcNAcylation catalyzed by O-GlcNAc transferase (OGT) plays an important role in the regulation of tumor glycolysis. However, the mechanism underlying OGT regulation remains largely unknown. Here, we showed that coactivator associated arginine methyltransferase 1 (CARM1) sensed changes of extracellular glucose levels in non-small cell lung cancer (NSCLC) cells.

Alteration of skin fibroblast steady state contributes to healing outcomes.

Fibroblasts display complex functions associated with distinct gene expression profiles that influence matrix production and cell communications and the autonomy of tissue development and repair. Thrombospondin-2 (TSP-2), produced by fibroblasts, is a potent angiogenesis inhibitor and negatively associated with tissue repair. Single-cell (sc) sequencing analysis on WT and TSP2KO skin fibroblasts demonstrate distinct cell heterogeneity.

Systolic blood pressure modifies the effect of endovascular thrombectomy in acute ischemic stroke: a mediation analysis.

Background: Systolic blood pressure (BP) is a key factor in the outcomes of patients with acute ischemic stroke (AIS) receiving endovascular thrombectomy (EVT). However, the factors that mediate the association between BP and clinical outcome are unclear.

Methods: Consecutive patients with AIS in the anterior circulation underwent continuous blood pressure monitoring for 24 hours.

Voltage-Induced Bromide Redox Enables Capacity Restoration of Fast-Charging Batteries.

Fast-charging lithium-ion batteries (LIBs) are essential for electric vehicles (EVs) to compete with conventional gasoline ones in terms of charging viability, yet the aggressive capacity drop in fast-charging scenarios gives rise to concerns regarding durability and sustainability. Herein, it is clarified that for fast-charging batteries, the excessive lithium (Li) plating on graphite anode inevitably brings capacity fading, and the concurrent accumulation of LiO-dominant passivation species that form dead Li is the main reason for their poor rechargeability. To refresh the passivated graphite, a voltage-induced activation mechanism is developed to leverage bromide (Br/Br ) redox couple for LiO and isolated Li activation in situ.

Bright, circularly polarized black-body radiation from twisted nanocarbon filaments.

Planck's law ignores but does not prohibit black-body radiation (BBR) from being circularly polarized. BBR from nanostructured filaments with twisted geometry from nanocarbon or metal has strong ellipticity from 500 to 3000 nanometers. The submicrometer-scale chirality of these filaments satisfies the dimensionality requirements imposed by fluctuation-dissipation theorem and requires symmetry breaking in absorptivity and emissivity according to Kirchhoff's law.

Assessing the effectiveness of measurement scales in evaluating the health-related quality of life in rare disease patients after treatment: a systematic review.

Background: Rare diseases often entail significant challenges in clinical management and health-related quality of life (HRQoL) assessment. HRQoL assessment tools for rare diseases show substantial variability in outcomes, influenced by disease heterogeneity, intervention types, and scale characteristics. The variability in reported quality of life (QoL) improvements following interventions reflects a need to evaluate the effectiveness of HRQoL assessment tools and understand their suitability across diverse contexts.

Post-transplant complications revealed by mycophenolate mofetil related transporters and metabolic enzymes gene polymorphisms in pediatric patients with hematological disorders.

Background: Haploidentical hematopoietic stem cell transplantation (Haplo-HSCT) serves as an important option for patients without an HLA matched donor in treating hematological disorders, while patients may experience various complications after transplantation. Mycophenolate mofetil (MMF), a cornerstone drug for graft-versus-host disease (GvHD) prophylaxis, effectively reduces the incidence of acute GvHD, and the efficacy of MMF varies among individuals associated with MMF-related transporters and metabolic enzymes single nucleotide polymorphisms (SNPs). However, limited studies have systematically reported the correlations between the MMF-related SNPs and post-transplant complications.

Blockage of polycystin-2 alleviates myocardial ischemia/reperfusion injury by inhibiting autophagy through the Ca/Akt/Beclin 1 pathway.

Autophagy is a well-conserved self-protection process that plays an important role in cardiovascular diseases. Excessive autophagy during myocardial ischemia/reperfusion injury (MIRI) induces calcium overload and the overactivation of an autophagic response, thereby aggravating cardiomyocyte damage. Polycystin-2 (PC2) is a Ca-permeable nonselective cation channel implicated in the regulation of autophagy.

Real-world studies of crizotinib in patients with ROS1-positive non-small-cell lung cancer: experience from China.

The treatment of non-small-cell lung cancer (NSCLC) has progressed from histology-oriented cytotoxic therapy to the era of molecular biology-oriented targeted therapy and immunotherapy. As the first tyrosine kinase inhibitor (TKI) targeting the pathway, crizotinib is widely used as a first-line regimen for -rearranged NSCLC. However, due to the paucity of solid data from randomized, controlled phase III clinical studies, clinicians often require more systematic, real-world data-based guidance for its optimal clinical use.

High-Throughput Quantification of miRNA-3'-Untranslated-Region Regulatory Effects.

MicroRNAs (miRNAs) regulate gene expression post-transcriptionally, primarily through binding sites in 3' untranslated regions (3' UTRs). While computational and biochemical approaches have been developed to predict miRNA binding sites on target messenger RNAs, reliable and high-throughput assessment of the regulatory effects of miRNAs on full-length 3' UTRs can still be challenging. Utilizing a miniaturized and high-throughput reporter assay, we present a 'pilot miRNA-targeting map', containing 4,994 successfully measured miRNA:3' UTR regulatory outputs by pairwise assays between 461 miRNAs and eleven 3' UTRs.

Autocatalytic Nucleation and Self-Assembly of Inorganic Nanoparticles into Complex Biosimilar Networks.

Self-replication of  molecules and microdroplets have been explored as models in prebiotic chemistry. An analogous process for inorganic nanomaterials would involve the autocatalytic nucleation of  nanoparticles-an area that remains largely uncharted. Demonstrating such systems would be both fundamentally intriguing and practically relevant, especially if the resulting particles self-assemble.

Analysis of therapeutic effect of cell reduction combined with intraperitoneal thermoperfusion chemotherapy in treatment of peritoneal pseudomyxoma.

Background: Pseudomyxoma peritonei is a rare tumor that can produce a biological behavior similar to that of a malignant tumor. Surgical resection combined with chemotherapy is the traditional treatment method, but the effect is not good. Cell reduction (CRS) combined with intraperitoneal thermoperfusion chemotherapy (HIPEC) has become a new method for the treatment of peritoneal pseudomyxoma (PMP).

Copper Ion-Chelated and Polydopamine-Modified Hydroxypropyl Methylcellulose Nanoparticles with Multiple Responses for Intelligent Pesticide Release and Improved Foliar Deposition.

Intelligent controlled-release nanopesticides have been a crucial tactic in advanced precision agriculture during the past few years, which can improve pesticide utilization and reduce environmental pollution. Herein, a novel hydroxypropyl methylcellulose-based nanopesticide carrier (PCH) with pH-/enzyme-/near-infrared multiple responses was constructed by the initial cross-linking with dimethyl diallyl ammonium chloride and the subsequent copper ion chelation and polydopamine coating. Avermectin (Av) was further loaded to create the intelligent pesticide release system (APCH) by antisolvent precipitation.

Maternal obesity may disrupt offspring metabolism by inducing oocyte genome hyper-methylation via increased DNMTs.

Maternal obesity has deleterious effects on the process of establishing oocyte DNA methylation; yet the underlying mechanisms remain unclear. Here, we found that maternal obesity disrupted the genomic methylation of oocytes using a high-fat diet (HFD) induced mouse model, at least a part of which was transmitted to the F2 oocytes and livers via females. We further examined the metabolome of serum and found that the serum concentration of melatonin was reduced.

Developing a framework for community childcare doctors to support community-based parental health education in preventing unintentional injuries among children aged below 6 years: a grounded theory exploration in eastern China.

Objective: Unintentional injuries are a major threat to children's health. Community-based health management services, which include the prevention of unintentional injuries among children aged 0-6 years, are important basic national public health services. However, deficiencies exist at this stage, such as community childcare doctors not being motivated to provide guidance.

Fast-speed and low-power-consumption optical phased array based on lithium niobate waveguides.

Fast scanning speed and low-power consumption are becoming progressively more and more important in realizing high-performance chiplet optical phased arrays (OPAs). Here, we successfully demonstrated integrated OPAs with multiple waveguides channels based on thin-film lithium niobate-on-insulator (LNOI) platform. Specifically, two lithium niobate (LN) OPA chips have been implemented with 32 and 48 channels LN waveguides, respectively, enabled by electro-optic modulations, which showcases the low power consumption (1.

Dysregulation in keratinocytes drives systemic lupus erythematosus onset.

Systemic lupus erythematosus (SLE) is a complex, multiorgan autoimmune disorder. Although it is widely believed that SLE originates from immune cell dysregulation, the etiology of SLE is not yet clear. Here, we propose a new theory in which SLE can be directly initiated by molecular alterations in keratinocytes rather than immune cells.
