Mater Today Bio

December 2024

Department of Orthopedics, Shanghai Changhai Hospital, Naval Medical University, Shanghai, 200433, China.

Article Synopsis
  • - Hydrogel microspheres are viewed as effective scaffolds for bone repair due to their biocompatibility and ability to adapt to irregular defect shapes, but improvements in bioactivity are still needed.
  • - The development of multi-bioactive microspheres combines methacrylated silk fibroin with encapsulated magnesium ascorbyl phosphate, promoting angiogenesis and osteogenic differentiation.
  • - A coating of polydopamine adds the ability to conform to bone defect shapes and provides photothermal stimulation, enhancing the overall effectiveness of the scaffold in promoting bone healing.

Caspase family in autoimmune diseases.

Autoimmun Rev

January 2025

Faculty of Anesthesiology, Changhai Hospital, Naval Medical University, Shanghai 200433, China; School of Anesthesiology, Naval Medical University, 168 Changhai Road, Shanghai 200433, China. Electronic address:

Programmed cell death (PCD) plays a crucial role in maintaining tissue homeostasis, with its primary forms including apoptosis, pyroptosis, and necroptosis. The caspase family is central to these processes, and its complex functions across different cell death pathways and other non-cell death roles have been closely linked to the pathogenesis of autoimmune diseases. This article provides a comprehensive review of the role of the caspase family in autoimmune diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), type 1 diabetes (T1D), and multiple sclerosis (MS).

An Auger electron-loaded theranostic biosensor triggered by the ACE2-mediated virus/host endocytosis.

Talanta

April 2025

Department of Nuclear Medicine, Shanghai Pudong Hospital, Fudan University Pudong Medical Center, Shanghai 201399, China. Electronic address:

Accurate diagnosis and effective antiviral strategies are critical to combat acute infection and to avoid damage to the host. Due to their restricted radiation range and energy, Auger electron emitters have shown potential as a RNA-destructing radionuclide therapy in oncology and infection. Focusing on the process of angiotensin-converting enzyme 2 (ACE2)-mediated endocytosis, Technetium-99m-labeled DX600 (Tc-DX600) was synthesized as an Auger electron vector to specifically bind to surface-expressed ACE2 proteins on 293T-hACE2 cells (293T cells stably expressing human ACE2), and Technetium-99m-loaded microvesicles (Tc-MVs) served as an antiviral tracer and effector in pseudovirus infection.

Article Synopsis
  • - The study compares the effectiveness of prostate-specific membrane antigen (PSMA) PET scans and multiparametric MRI (mpMRI) in identifying lymph node metastasis (LNM) in prostate cancer, focusing on existing research up to August 2024.
  • - Results from 23 articles involving 3,041 patients reveal that PSMA PET has higher sensitivity (74%) compared to mpMRI (45%) for detecting LNM, while both methods show similar specificity (96% for PSMA PET and 92% for mpMRI).
  • - The conclusion indicates that PSMA PET is more effective for initial cancer staging, but no significant difference in specificity exists between the two methods, suggesting the need for further research to refine imaging

This study compared Ga-FAPI-46 PET/CT, F-fluorodeoxyglucose (FDG) PET/CT, and contrast-enhanced MRI (CE-MRI) for glioma imaging, classification, and recurrence detection and explored PET parameters and molecular pathological profiles. Between June 2020 and June 2024, we prospectively enrolled patients with space-occupying lesions in the brain or previously treated gliomas. All patients underwent sequential CE-MRI, Ga-FAPI-46, and F-FDG PET/CT.

Roles of macrophages in lupus nephritis.

Front Pharmacol

November 2024

Department of Nephrology, Wenzhou Central Hospital, Wenzhou, China.

LN is a serious complication of systemic lupus erythematosus (SLE), affecting up to 60% of patients with SLE and may lead to end-stage renal disease (ESRD). Macrophages play multifaceted roles in the pathogenesis of LN, including clearance of immune complexes, antigen presentation, regulation of inflammation, and tissue repair. Macrophages are abundant in the glomeruli and tubulointerstitium of LN patients and are positively correlated with serum creatinine levels and the severity of renal pathology.

The interaction of adenosine and dopamine in modulating the consequences of central nervous system oxygen toxicity.

J Appl Physiol (1985)

January 2025

Department of Diving and Hyperbaric Medicine, PLA Naval Medical Center, Naval Medical University, Shanghai, People's Republic of China.

Hyperbaric oxygen (HBO) refers to pure oxygen with a pressure greater than 1 atmospheres absolute (ATA), and when the pressure is too high, it can cause convulsive attacks. Adenosine and dopamine have been shown to be closely associated with HBO-induced convulsion seizures, and their receptors exhibited a coexisting relationship of mutual antagonism on the membrane of nerve cells. We explored the influence of adenosine and dopamine interplay on the occurrence of oxygen convulsion.

Background: Extra-articular distal humerus locking plates (EADHPs) have been widely employed for the treatment of extra-articular fractures of the distal humerus, but interference with the radial nerve and poor fastening of distal fracture fragments by screws remain. The aim of this study is to evaluate the clinical and imaging effects of the anterolateral approach in the treatment of extra-articular fractures of the distal humerus with the upside-down use of proximal humerus internal locking system (PHILOS) plates in front of the humerus.

Method: A retrospective analysis (10/2018-10/2022) was conducted on the clinical data of patients with extra-articular fractures of the distal humerus treated with the upside-down use of the PHILOS via the anterolateral approach.

Article Synopsis
  • Chronic myelomonocytic leukemia (CMML) is a type of blood cancer where allogeneic hematopoietic stem cell transplantation (allo-HSCT) is currently the only curative treatment, although not suitable for all patients, and relapse is a common issue.
  • A nationwide study analyzed data from 238 CMML patients who underwent allo-HSCT across 27 medical centers and 307 patients from a research database to establish a risk scoring system to predict early relapse based on certain prognostic factors.
  • Four key factors were identified that significantly increased the risk of relapse: bone marrow blasts over 10%, age greater than 60 years, low hemoglobin levels, and specific gene mutations, leading to a scoring system that categor
