Single-Nucleus RNA Sequencing Reveals That Gabra6 Neurons in Prefrontal Cortex Promote the Progression of PTSD After Shockwave-Induced TBI.

Shockwave-induced traumatic brain injury (TBI) results in the onset of post-traumatic stress disorder (PTSD), triggered either by the TBI itself or other stressors. However, the interplay and underlying mechanisms of how these factors synergistically induce PTSD remain inadequately elucidated. Here, mice in the TBI (induced by biological shock tube blast injury) and PTSD (induced by single prolonged stress method) groups both displayed symptoms of PTSD behaviors, with the TBI+PTSD (composite model) group exhibiting more severe manifestations.

Background: Some patients treated with ursodeoxycholic acid (UDCA) or combined fenofibrate had well-controlled biochemical parameters but high liver stiffness, and the prognosis as well as therapeutic options for these patients may be an area worthy of further exploration.

Aims: To explore the prognosis and treatment of patients with low-risk and high liver stiffness.

Methods: A retrospective study included 424 cases of UDCA monotherapy and 102 cases of combined fenofibrate treatment.

The relationship between spiritual climate and secondary traumatic stress in ICU nurses: The mediating role of moral resilience.

Background: Secondary traumatic stress is acknowledged as a substantial psychological risk factor in nursing practice with the potential to negatively impact nurses' mental health. However, little is known about the mechanisms underlying the spiritual climate and secondary traumatic stress among ICU nurses.

Objectives: This study aimed to assess the spiritual climate, moral resilience, and secondary traumatic stress in Chinese ICU nurses and to investigate whether moral resilience mediates the relationship between spiritual climate and secondary traumatic stress.

Impaired Basal Forebrain Cholinergic Neuron GDNF Signaling Contributes to Perioperative Sleep Deprivation-Induced Chronicity of Postsurgical Pain in Mice Through Regulating Cholinergic Neuronal Activity, Apoptosis, and Autophagy.

Aims: This study investigated the roles of lateral basal forebrain glial cell line-derived neurotrophic factor (GDNF) signaling and cholinergic neuron activity, apoptosis, and autophagy dysfunction in sleep deprivation-induced increased risk of chronic postsurgical pain (CPSP) in mice.

Methods: Sleep deprivation (6 h per day from -1 to 3 days postoperatively) was administered to mice receiving skin/muscle incision and retraction (SMIR) to determine whether perioperative sleep deprivation induces mechanical and thermal pain hypersensitivity, increases the risk of chronic pain, and causes changes of basal forebrain neurons activity (c-Fos immunostaining), apoptosis (cleaved Caspase-3 expression), autophagy (LC3 and p62 expression) and GDNF expression. Adeno-associated virus (AAV)-GDNF was microinjected into the basal forebrain to see whether increased GDNF expression could reverse sleep deprivation-induced changes in pain duration and cholinergic neuron apoptosis and autophagy.

Previous research has shown that perceived organizational support and compassion fatigue are linked to nurses' caring behaviors.

The Potential Therapeutic Targets of Anlotinib in Osteosarcoma: Characterization Based on Patient-Derived Xenografts and Next-Generation Sequencing.

Background: The aim of this study was to analyze the potential therapeutic targets of anlotinib using the patient-derived xenografts (PDX) and evaluate the efficacy of the combination of chemotherapy and anlotinib in osteosarcoma patients before surgery.

Methods: Forty-three osteosarcoma specimens were used to establish the PDX model in mice, resulting in Twenty-one PDX successful models. Eventually, six models were randomly selected for the pharmacodynamic experiment.

An in-depth analysis of the personal factors and their pathways in shaping self-directed learning abilities among undergraduate nursing students.

Background: Developing self-directed learning in undergraduate nursing students affects not only their learning and their lives, but also their future professional development and the quality of their future practice in clinical nursing. Hence, it is paramount to prioritize and cultivate self-directed learning capabilities among undergraduate nursing students, as this not only enhances their academic pursuits but also equips them with essential lifelong learning skills crucial for the dynamic healthcare landscape.

Objective: To delve into the intricate relationship between metacognitive abilities and self-directed learning practices among nursing students, while concurrently examining the mediating roles of psychological capital and interpersonal communication in this interconnected framework.

[Analysis of hearing effects of three ossicular reconstruction methods in 123 cases of atticotomy surgery].

Retrospective analysis of clinical data of 123 patients with atticotomy, exploring the clinical characteristics of patients undergoing atticotomy and the efficacy of hearing reconstruction methods. 123 patients with atticotomy were divided into three groups according to the ossicular chain treatment method: preservation of the ossicular chain group（37 cases）, cartilage elevation of stapes group（49 cases）, and PORP group（37 cases）.

Research on evaluation of fetal right ventricular function in normal and diabetic pregnant women during mid to late pregnancy using automated MPI ultrasound detection technology.

fetal circulatory characteristics differ from those after birth; the right ventricle assumes more than 60% of the workload in the systemic circulation before birth. The right ventricle automated myocardial performance index (AM+MPI) is a simple, time-efficient, and stable assessment method used to evaluate overall cardiac function. This study aimed to apply the right ventricle AM+MPI technique to explore its role in normal mid-to-late pregnancy fetal cardiac function and compare the AM+MPI differences between diabetic and normal fetuses.

PD-1CD8 T Cell-Mediated Hepatocyte Pyroptosis Promotes Progression of Murine Autoimmune Liver Disease.

The specific mechanisms underlying effector pathways in autoimmune liver disease remain enigmatic and therefore constructing appropriate murine models to investigate disease pathogenesis becomes critical. A spontaneous severe murine model of autoimmune liver disease has been previously established in dnTGFβRII Aire mice, exhibiting disease phenotypes that resemble both human primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH). The data suggests that auto-reactive liver-specific CD8 T cells are the primary pathogenic cells in liver injury.
