Developing wound dressings with excellent mechanical properties, wound protection, comfort, angiogenic capacity and therapeutic effects is significant for effective treatments, yet remains challenging. Herein, we have designed a novel HAP-Alg composite dressing comprising a complementary ultralong hydroxyapatite (HAP) nanowire bio-paper and calcium alginate hydrogel.

Sports training improves motor function after spinal cord injury by regulating microtubule dynamics.

Spinal cord injury (SCI) often results in persistent disabilities, primarily due to deficient axon regeneration and irreversible neuronal loss. Sports training is a widely adopted intervention in clinical practice and research to promote axonal sprouting and synaptic plasticity, thereby improving motor function after SCI. However, the precise mechanisms by which sports training improves motor function after SCI remain incompletely understood.

Development and validation of a one-step assay for genetic testing in spinal muscular atrophy MALDI-TOF MS.

Spinal muscular atrophy (SMA) is a fatal neuromuscular disorder primarily attributed to the homozygous deletion of the survival motor neuron 1 () gene, with disease severity closely correlated to the copy number variations (CNV) of . Conventional methodologies, however, fail to provide a comprehensive gene overview of and are often both time-intensive and costly. In this study, we present a novel one-step MALDI-TOF MS assay for SMA gene testing.

Background:  Hemimasticatory spasm (HMS) is an uncommon movement disorder of the trigeminal motor rootlet characterized by unilateral, involuntary, and paroxysmal contractions of the muscles of mastication. The mechanisms for HMS are still unclear, and an efficient treatment strategy still needs to be developed. This study aims to investigate the clinical features and surgical treatment of HMS.

Effectiveness of low-load resistance training with blood flow restriction vs. conventional high-intensity resistance training in older people diagnosed with sarcopenia: a randomized controlled trial.

Low-load resistance training with blood flow restriction (LRT-BFR) has shown potential to improve muscle strength and mass in different populations; however, there remains limited evidence in sarcopenic people diagnosed with sarcopenia criteria. This study systematically compared the effectiveness of LRT-BFR and conventional high-intensity resistance training (CRT) on clinical muscle outcomes (muscle mass, strength and performance), cardiovascular disease (CVD) risk factors and sarcopenia-related biomarkers of older people with sarcopenia. Twenty-one older individuals (aged 65 years and older) diagnosed with sarcopenia were randomly assigned to the LRT-BFR (20%-30% one-repetition maximum (1RM), n = 10) or CRT (60%-70% 1RM, n = 11) group.

A clinicopathological and molecular series of five TFEB-altered renal cell carcinoma (RCC) cases: highlighting an aggressive subset of TFEB-rearranged RCC concomitant with TFEB amplification/gene copy number gains.

The classification of TFEB-altered renal cell carcinoma (RCC) has been revised to include TFEB-rearranged RCC and TFEB-amplified RCC in the 2022 World Health Organization (WHO) Classification of Tumors of the Urinary System. Given the wide spectrum of TFEB-altered RCC in terms of morphology and clinical behavior, an accurate diagnosis is challenging yet crucial, particularly in aggressive cases. Moreover, the concurrence of TFEB gene rearrangement and amplification/gene copy number (GCN) gains was also observed, but there was limited knowledge of these cases.

Knowledge, attitude and practice towards arthroscopic shoulder surgery in patients with rotator cuff tear: cross-sectional study.

Objectives: This cross-sectional study aimed to explore the knowledge, attitude and practice (KAP) of patients with rotator cuff tears towards arthroscopic shoulder surgery (ASS), based on the hypothesis that the knowledge of the procedure among patients would be sufficient, which in turn might influence their practice and attitude.

Design: Cross-sectional study.

Setting: Patients were recruited from Tong Ren Hospital between September and October 2022.

Chinese expert consensus on allergen component resolved diagnosis.

Background: Allergen component resolved diagnosis (CRD) is a method for identifying specific protein molecules that cause hypersensitivity. Unlike traditional methods that use crude allergen extracts containing multiple component species, CRD focuses on individual allergen protein molecules for more precise diagnosis. The World Allergy Organization (WAO) recommends CRD as a supplement to clinical history and allergen extract testing, and in some cases, it can replace crude extract tests.

Global, regional, and national burden of soft tissue and extraosseous sarcomas from 1990 to 2021.

Objective: To conduct a comprehensive global epidemiological investigation of soft tissue and extraosseous sarcomas from 1990 to 2021 and uncover the demographic and geographical variations.

Methods: Incidence and death data of soft tissue and extraosseous sarcomas between 1990 and 2021 were derived from the Global Burden of Disease 2021. The estimated annual percentage change was calculated.

3D printed cell-free bilayer porous scaffold based on alginate with biomimetic microenvironment for osteochondral defect repair.

Despite significant progress in repairing osteochondral injuries using 3D printing technology, most cartilage layer scaffolds are made of degradable materials, making it difficult to simultaneously provide extracellular matrix functionality while replicating the mechanical properties of natural cartilage layers. Additionally, their degradation rate is challenging to align with cartilage regeneration. Furthermore, double-layer scaffolds commonly used for repairing osteochondral often exhibit inadequate bonding between the cartilage layer scaffolds and bone layer scaffolds.

Machine learning-guided synthesis of nanomaterials for breast cancer therapy.

Breast cancer is a common malignant tumor, which mostly occurs in female population and is caused by excessive proliferation of breast epithelial cells. Breast cancer can cause nipple discharge, breast lumps and other symptoms, but these symptoms lack certain specificity and are easily confused with other diseases, thus affecting the early treatment of the disease. Once the tumor progresses to the advanced stage, distant metastasis can occur, leading to dysfunction of the affected organs, and even threatening the patients' lives.

Nanozyme-enhanced injectable hyaluronic acid-based hydrogel for the treatment of osteoarthritis.

The progression of osteoarthritis (OA) is dramatically accelerated by excessive reactive oxygen species (ROS)-induced apoptosis of chondrocytes and the inflammatory response of synovial macrophages. In this study, we developed an injectable hydrogel with a catalase-mimicking nanozyme activity as a therapeutic agent for OA. In vitro experiments confirmed that the HA and peroxide-mimetic nanoenzyme-enhanced hydrogel, containing ε-polylysine/MnCoO (ε-PLE/MnCoO) nanoparticles, continuously eliminated ROS and inflammatory cytokines while promoting the polarization of inflammatory macrophages (M1 phenotype) towards anti-inflammatory macrophages (M2 phenotype) in dysfunctional microenvironments.
