The characteristics of the tumor microenvironment (TME) of pancreatic cancer include an abundant stroma, hypoxia, insufficient blood supply and high degree of immunosuppression. Therefore, overcoming the TME conditions to reach a hypermetabolic state is a concern for the treatment of pancreatic cancer. Previous studies have demonstrated that tumor cells adapt to the TME by activating or increasing the expression level of ACSS2 under metabolic stress.

Through a genetic screen in Drosophila, we identify the phosphatase Pp1-87B as an essential regulator of JNK signaling crucial for eliminating scrib-deficient precancerous cells during tumor-suppressive cell competition. Mechanistically, impaired Pp1-87B activates JNK signaling via the Moe-Rho1 axis.

Introduction: Diabetic Foot (DF), as a serious complication of diabetes, is closely related to major adverse cardiovascular events (MACE) and mortality. However, research on predictive models for the MACE risk in DF patients is not sufficient. The purpose of this study is to construct a prognostic model for the MACE risk in patients with diabetic foot ulcers and provide a reference tool for clinical individualized management.

This study aims to assess the long-term pancreatic metabolic outcomes and QoL in patients following MIEN involving MPD ERR.

Objective: Treatment options for intestinal Behçet's disease (BD) are limited. Despite the proven efficacy of infliximab and adalimumab, there is an urgent need to identify predictive factors for inadequate response or non-response to anti-TNF agents.
Methods: We conducted a retrospective cohort study involving 71 patients diagnosed with intestinal BD and treated with anti-TNF across four hospitals from August 2018 to December 2024.

Objective: To investigate the short-term efficacy and safety of low-dose venetoclax combined with CHG (cytarabine+homoharringtonine+G-CSF) priming regimen in patients with acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS) ineligible for intensive chemotherapy.
Methods: The data of 14 patients with AML or high-risk MDS admitted to the department of hematology/oncology of the First Hospital of Tsinghua University and 2 cooperative institutions from July 2022 to August 2023 were retrospectively analyzed. All the patients were treated with low-dose venetoclax combined with CHG priming regimen and the early induction (one course) efficacy and adverse reactions were observed.
Interorgan communication is vital for tissue homeostasis and health in multicellular organisms, and its disruption can lead to diseases such as cancer. Adipose tissue acts as a key endocrine center, secreting cytokines that influence remote organs. Despite clear links between obesity and increased cancer risk, the underlying mechanisms are unclear.

Aim: To investigate the components for lipid metabolism of and its hypoglycemic effects, providing a basis for its broader application.
Methods: The lipid metabolism of under different growth conditions was analyzed using lipidomics.
Programmed cell death protein 1 (PD-1) expression on T cells has been implicated in the pathogenesis of autoimmune diseases; however, the functional role of programmed death-ligand 1 (PD-L1) expression on B cells remains insufficiently characterized, particularly in the context of CD4 T cell-mediated regulation in systemic lupus erythematosus (SLE). Flow cytometric analysis revealed that PD-L1 B cells exhibited upregulated surface expression of the co-stimulatory molecules CD80 and CD86, alongside a concomitant downregulation in the expression of the antigen-presenting molecule human leukocyte antigen DR (HLA-DR). Furthermore, an elevated frequency of class-switched PD-L1 B cells was observed in the peripheral blood of patients with SLE.

Purpose: This study aims to explore the impact of wearing peripheral defocus spectacle lenses (PDSL) on cylindrical refractive error (CYL) in myopic children.
Methods: This study included 1057 myopic children and divided the participants into three groups: the HAL group (spectacle lens with highly aspherical lenslets), the MPV group (spectacle lens based on manipulating peripheral vision), and a control group (without myopia control interventions). The study analyzed the effect of wearing PDSL on changes in spherical equivalent refraction, CYL, and corneal astigmatism (CA).
A green, efficient, and environmentally friendly electrochemical strategy was developed for synthesizing a series of selenoheterocyclic compounds. The antitumor activities of these compounds were evaluated, revealing that compounds , , and demonstrated remarkable antitumor efficacy. These compounds effectively inhibited lung cancer by inducing cell apoptosis, causing DNA damage, and suppressing the progression of epithelial-mesenchymal transition.

Background: The oncological efficacy of laparoscopic distal pancreatectomy in left-sided pancreatic cancer remains controversial.

Clathrin-mediated endocytosis (CME) plays a key role in the internalization of plasma membrane-localized proteins, lipids and extracellular substances; however, the regulatory mechanism of CME in plants is unclear. In this work, we demonstrated that molecular chaperon HSP70-9 is required for CME in Arabidopsis thaliana. Knocking out the HSP70-9 gene led to auxin-related phenotypes and the accumulation of auxin efflux carrier PINs in root cells, indicating that HSP70-9 is involved in the PIN trafficking process.

Background: The role of diet in aging is crucial, yet research findings on how specific diets influence human aging remain inconsistent. Understanding the relationship between dietary factors and aging could inform interventions to promote healthier aging outcomes.
Methods: We analyzed data from the UK Biobank baseline survey and a 24-hour dietary assessment survey to investigate the association between diet and aging.
Background: Skin wounds are highly common in diabetic patients, and with increasing types of pathogenic bacteria and antibiotic resistance, wounds and infections in diabetic patients are difficult to treat and heal.
Aim: To explore the effects of betaine ointment (BO) in promoting the healing of skin wounds and reducing the inflammation and apoptosis of skin cells in microbially infected diabetic mice.
Methods: By detecting the minimum inhibitory concentrations (MICs) of betaine and plant monomer components such as psoralen, we prepared BO with betaine as the main ingredient, blended it with traditional Chinese medicines such as gromwell root and psoralen, and evaluated its antibacterial effects and safety and .
Objective: The objective of the study is to analyze and explore the characteristics of the video head impulse test (vHIT) for light cupula in the idiopathic horizontal semicircular canal and compare them with those of horizontal semicircular canal cupulolithiasis (HC-cu) in order to investigate the potential mechanism involved.
Methods: Data from 51 cases of idiopathic light cupula and 42 cases of horizontal semicircular canal cupulolithiasis were retrospectively analyzed. The positional nystagmus features, vHIT anomaly rate, gain value, saccades, and other indicators were compared.
Mitochondrial DNA (mtDNA) is indispensable for mitochondrial function and is maintained by DNA repair, turnover, mitochondrial dynamics and mitophagy, along with the inherent redundancy of mtDNA. Base excision repair (BER) is a major DNA repair mechanism in mammalian mitochondria. Mitochondrial BER enzymes are implicated in mtDNA-mediated immune response and inflammation.

Axonemal dynein, the macromolecular machine that powers ciliary motility, assembles in the cytosol with the help of dynein axonemal assembly factors (DNAAFs). These DNAAFs localize in cytosolic foci thought to form via liquid-liquid phase separation. However, the functional significance of DNAAF foci formation and how the production and assembly of multiple components are so efficiently coordinated, at such enormous scale, remain unclear.

However, the mechanisms underlying the induction of tumor malignancy upon inhibition of steroid hormone signaling remain poorly understood. Here, we demonstrate that Drosophila malignant epithelial tumors show a similar reduction in ecdysone signaling, the main steroid hormone pathway.

Creating an ecological security pattern is crucial for balancing the sustainable development of areas where human activities and the natural environment intersect. Using Hefei, an internationally recognized Wetland City, as a case study, we extracted ecological sources through ecological service function (ESF) analysis and morphological spatial pattern analysis (MSPA) core area connectivity analysis. Based on these ecological sources, we developed an ecological resistance surface system and identified ecological corridors and nodes using circuit theory.
