The Insulated Gate Bipolar Transistor (IGBT) is a crucial power semiconductor device, and the integrity of its internal structure directly influences both its electrical performance and long-term reliability. However, the precise semantic segmentation of IGBT ultrasonic tomographic images poses several challenges, primarily due to high-density noise interference and visual distortion caused by target warping. To address these challenges, this paper constructs a dedicated IGBT ultrasonic tomography (IUT) dataset using Scanning Acoustic Microscopy (SAM) and proposes a lightweight Multi-Scale Fusion Network (LMFNet) aimed at improving segmentation accuracy and processing efficiency in ultrasonic images analysis.

Background: Serum hepatitis B surface antigen (HBsAg) < 100 IU/mL has been recently proposed as one of the key criteria of 'partial cure' in patients with chronic hepatitis B virus (HBV) infection. We analysed the clinical prognosis of hepatitis B e antigen (HBeAg)-negative untreated patients with HBsAg < 100 IU/mL and normal alanine aminotransferase (ALT) levels.

Methods: Five hundred and twenty-one untreated patients with HBeAg negativity, HBsAg < 100 IU/mL and normal ALT levels were included from three hospitals.

Article Synopsis
  • Hepatitis C virus (HCV) is a significant public health issue in China, impacting over 10 million people, prompting the HEAL program, which aimed to improve HCV surveillance and linkage to care in tertiary hospitals.
  • The intervention included education for non-infectious disease physicians and a patient-navigator system to streamline testing and treatment for patients who tested positive for HCV.
  • Following the HEAL program implementation, screening rates and follow-up for HCV increased significantly, leading to a higher number of confirmed active infections and improved patient linkage to care.

Objective: To investigate the clinical value of whole-exome sequencing (WES) in the diagnosis of foetuses with central nervous system (CNS) abnormalities but having a normal karyotyping and chromosomal microarray result.

Method: During the period of 2016-2022, there were a total of 149 foetuses with CNS abnormalities but having negative karyotyping and chromosomal microarray analysis results; WES was performed on these foetuses and their parents. Variants were classified according to ACMG guidelines, and the association of pathogenic variants with specific types of CNS abnormalities was explored.

Article Synopsis
  • * A study of 304 hospitalized SFTS patients from 2010 to 2022 found that those with GI symptoms had different demographic and lab results, such as a lower percentage of males and higher enzyme levels, compared to those without GI symptoms.
  • * Despite the prevalence of GI symptoms, the study concluded that they did not significantly impact mortality rates or the likelihood of ICU admission, indicating they are not an independent risk factor for worse outcomes in SFTS patients.

Background: Open fractures are challenging due to susceptibility to Staphylococcus aureus infections. This study examines the impact of Vancomycin-Loaded Calcium Sulfate (VLCS) and negative pressure wound therapy (NPWT) on macrophage behavior in enhancing healing and infection resistance. Both VLCS and NPWT were evaluated individually and in combination to determine their effects on macrophage polarization and infection resistance in open fractures.

Chronic obstructive pulmonary disease (COPD) is a prevalent lung condition characterized by airflow obstruction, disability, and high mortality rates. Magnolol (MA), known for its anti-inflammatory and antioxidant properties, holds the potential for alleviating COPD symptoms. However, MA faces challenges like poor aqueous solubility and low bioavailability.

Article Synopsis
  • Intensive chemotherapy is the primary treatment for acute myeloid leukemia (AML), but its effectiveness is limited by heart-related side effects, known as cardiotoxicity.
  • Research showed that the angiotensin II receptor type 1 (AGTR1) is connected to both AML and cardiovascular disease, and blocking AGTR1 enhances the effectiveness of chemotherapy while protecting the heart.
  • The study highlighted that AGTR1-Notch1 signaling plays a crucial role in regulating genes related to cancer stemness and chemotherapy resistance in AML, suggesting a potential strategy to improve treatment outcomes for patients.

Introduction: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel bunyavirus infection with a high lethality rate. The purpose of this study was to investigate the changes in coagulation parameters in patients with SFTS, aiming to provide clinical evidence for early diagnosis, treatment, and disease analysis.

Methods: A total of 40 patients with SFTS attended from April 1, 2020 to May 21, 2022 in Nanjing Drum Tower Hospital were selected and grouped according to the duration of the disease, mild and severe disease, cure and death, with 50 healthy physical examiners as controls, and the risk of severe and death disease was predicted using ROC curves.

Article Synopsis
  • Prenatal inflammation due to intrauterine exposure (IUI) is linked to preterm birth (PTB) and increased risk of neurodevelopmental disorders, influencing gut microbiota and metabolite profiles.
  • Research using a mouse model showed that LPS-induced IUI elevated PTB rates and inflammation in placental tissues without major changes in microbial diversity, but significantly affected species abundance and metabolite profiles.
  • Treatment with pyruvic acid improved outcomes by reducing PTB rates and placental inflammation, suggesting that gut microbiota and metabolites may play a role in the mechanisms behind IUI and PTB, warranting further research.

Great effort has been made to encapsulate or coat living mammalian cells for a variety of applications ranging from diabetes treatment to three-dimensional printing. However, no study has reported the synthesis of a biomimetic bacterial capsule to display high-affinity aptamers on the cell surface for enhanced cell recognition. Therefore, we synthesized an ultrathin alginate-polylysine coating to display aptamers on the surface of living cells with natural killer (NK) cells as a model.

Allogeneic hematopoietic stem cell transplantation (alloSCT) is, in many clinical settings, the only curative treatment for acute myeloid leukemia (AML). The clinical benefit of alloSCT greatly relies on the graft-versus-leukemia (GVL) effect. However, AML relapse remains the top cause of posttransplant death; this highlights the urgent need to enhance GVL.

Secondary infection in patients with sepsis triggers a new wave of inflammatory response, which aggravates organ injury and increases mortality. Trained immunity boosts a potent and nonspecific response to the secondary challenge and has been considered beneficial for the host. Here, using a murine model of polymicrobial infection, we find that the primary infection reprograms granulocytes to boost enhanced inflammatory responses to the secondary infection, including the excessive production of inflammatory cytokines, respiratory burst, and augmented phagocytosis capacity.
