Exploring the clinical value of procalcitonin, c-reactive protein, white blood cell count, and neutrophil-to-lymphocyte ratio in the early diagnosis of bloodstream infections in children.

Backgroud: In the diagnosis of bloodstream infections (BSI) in children, compared to the gold standard of blood culture, markers in the blood offer advantages such as rapid results and cost-effectiveness. Therefore, we investigated the clinical value of procalcitonin (PCT), C-reactive protein (CRP), white blood cell count (WBC), and neutrophil-to-lymphocyte ratio (NLR) in the early diagnosis of BSI in children.

Methods: This study included a retrospective analysis of 309 suspected BSI cases and patients were categorized into 2 groups based on blood culture results: blood culture-positive group, and blood culture-negative group.

Effects of Chemical Composition and Cross-Linking Degree on the Thermo-Mechanical Properties of Bio-Based Thermosetting Resins: A Molecular Dynamics Simulation Study.

Bio-based epoxy resins have received significant attention in terms of concerns regarding carbon emission. Epoxidized soybean oil (ESO) derived from sustainable feedstock has been widely used to blend with traditional diglycidyl ether of bisphenol-A (DGEBA) to replace some of the petroleum-based components. In this work, molecular dynamics (MD) simulations were applied to track the network formation and predict the performance of methyl hexahydrophthalic anhydride (MHHPA)-cured ESO/DGEBA blend systems.

Using targeted second-generation sequencing technique to guide clinical diagnosis and the effect of medication on the therapeutic effect and prognosis of respiratory tract infection in children: An observational study.

To explore the effect of targeted second-generation sequencing technique to guide clinical diagnosis and medication on the therapeutic effect and prognosis of respiratory tract infection (RTI) in children. During January 2021 to June 2022, 320 children with RTI cured were selected in our hospital as the object of this retrospective study. The control group accepted empirical broad-spectrum antibacterial therapy and the observation group accepted targeted second-generation sequencing technique to guide diagnosis and medication.

Machine Learning Analysis Classifies Patients with Primary Angle-Closure Glaucoma Using Abnormal Brain White Matter Function.

Objective: Primary angle-closure glaucoma (PACG) is a globally prevalent, irreversible eye disease leading to blindness. Previous neuroimaging studies demonstrated that PACG patients were associated with gray matter function changes. However, whether the white matter(WM) function changes in PACG patients remains unknown.

Altered functional connectivity between the default mode network in primary angle-closure glaucoma patients.

Previous studies have recognized glaucoma as a neurodegenerative disease that causes extensive brain damage and is closely associated with cognitive function. In this study, we employed functional MRI to examine the intrinsic functional connectivity patterns of the default mode network (DMN) in patients diagnosed with primary angle-closure glaucoma (PACG), exploring its association with cognitive dysfunction. A total of 34 patients diagnosed with PACG and 34 healthy controls (HC), who were matched in terms of sex, age, and education, were included in the control group.

Allergic diseases aggravate the symptoms of SARS-CoV-2 infection in China.

Background: The relationship between allergic diseases and the adverse outcomes of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been a subject of controversy. This study aimed to investigate the association between allergic diseases and the incidence and severity of symptoms in SARS-CoV-2 infection.

Methods: Clinical data of individuals, including children and their parents, infected with SARS-CoV-2 from December 2022 to January 2023 in China were retrospectively analyzed.

Parathyroid hormone enhances the therapeutic effect of mesenchymal stem cells on temporomandibular joint osteoarthritis in rats.

Objectives: Temporomandibular joint osteoarthritis (TMJOA) is a degenerative disease affecting the joint, which is characterized by injury to the articular cartilage, as well as changes in the synovial and subchondral bone. TMJOA has a high incidence rate, without any effective treatment. Despite the therapeutic potential of mesenchymal stem cells (MSCs) in various diseases, their efficacy in treating TMJOA is constrained by the local hypoxic conditions and elevated reactive oxygen species (ROS) environment within the damaged temporomandibular joint.

FOXF1 attenuates TGF‑β1‑induced bronchial epithelial cell injury by inhibiting CDH11‑mediated Wnt/β‑catenin signaling.

Forkhead box F1 (FOXF1) has been reported to be associated with lung development. However, the role of FOXF1 in asthma is still not fully understood. In the present study, the biological role and the potential mechanism of FOXF1 was explored in transforming growth factor β1 (TGF-β1)-induced bronchial epithelial cell injury.

Huashi baidu granule in the treatment of pediatric patients with mild coronavirus disease 2019: A single-center, open-label, parallel-group randomized controlled clinical trial.

Since late February 2022, a wave of coronavirus disease 2019 (COVID-19) mainly caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant rapidly appeared in Shanghai, China. Traditional Chinese medicine treatment is recommended for pediatric patients; however, the safety and efficacy remain to be confirmed. We conducted a single-center, open-label, parallel-group randomized controlled trial to assess the efficacy and safety of a Chinese herb compound, Huashi Baidu granule (HSBDG) in pediatric patients with laboratory-confirmed mild COVID-19.

Bivalirudin exerts antiviral activity against respiratory syncytial virus-induced lung infections in neonatal mice.

Respiratory syncytial virus (RSV) is the most common cause of small airways inflammation in the lungs (bronchiolitis) in neonates and immunocompromised adults. The deregulation of cellular and plasma components leads to increased morbidity and mortality. The activation of the clotting cascade plays a key role in the progression of disease severity during viral infection.

Facile Synthesis of Thermoplastic Polyamide Elastomers Based on Amorphous Polyetheramine with Damping Performance.

Novel thermoplastic polyamide elastomers (TPAEs) consisting of long-chain semicrystalline polyamide 1212 (PA1212) and amorphous polyetheramine were synthesized via one-pot melt polycondensation. The method provides accessible routes to prepare TPAEs with a high tolerance of compatibility between polyamide and polyether oligomers compared with the traditional two-step method. These TPAEs with 10 wt % to 76 wt % of soft content were obtained by reaction of dodecanedioic acid, 1,12-dodecanediamine, and poly(propylene glycol) (PPG) diamine.

Age-specific risk factors of severe pneumonia among pediatric patients hospitalized with community-acquired pneumonia.

Background: Risk factors that predispose the development of severe community-acquired pneumonia (CAP) among pediatric CAP patients of different age ranges are yet to be identified.

Methods: We retrospectively analyzed pediatric in-patients (< 6 years old) diagnosed with CAP in our hospital. We subdivided patients into four age groups (< 6 months, 6 months-1 year, 1-2 years, and 2-6 years).

Boron Quantum Dots for Photoacoustic Imaging-Guided Photothermal Therapy.

Photothermal therapy is a new type of tumor therapy with great potential. An ideal photothermal therapy agent should have high photothermal conversion effect, low biological toxicity, and degradability. The development of novel photothermal therapy agents with these properties is of great demand.

Nucleoporin 107 facilitates the nuclear export of Scn5a mRNA to regulate cardiac bioelectricity.

Nucleoporins (Nups) are known to be functional in nucleo-cytoplasmic transport, but the roles of nucleoporins in nonproliferating cells, such as cardiac myocytes, are still poorly understood. In this study, we report that Nup107 regulates cardiac bioelectricity by controlling the nucleo-cytoplasmic trafficking of Scn5a mRNA. Overexpression of Nup107 induced the protein expression of Scn5a rather than that of other ion channels, with no effects of their mRNA levels.
