Automatic and accurate reconstruction of long-range axonal projections of single-neuron in mouse brain.

Single-neuron axonal projections reveal the route map of neuron output and provide a key cue for understanding how information flows across the brain. Reconstruction of single-neuron axonal projections requires intensive manual operations in tens of terabytes of brain imaging data and is highly time-consuming and labor-intensive. The main issue lies in the need for precise reconstruction algorithms to avoid reconstruction errors, yet current methods struggle with densely distributed axons, focusing mainly on skeleton extraction.

Myostatin induces subchondral bone destruction and cartilage matrix degradation through upregulation of the Wnt/β-catenin pathway during patellofemoral osteoarthritis.

Background: The pathogenesis of patellofemoral osteoarthritis (PFOA) is not fully understood. The aim of this project was to investigate the role and mechanism of myostatin (MSTN) in PFOA pathogenesis.

Methods: Fifteen New Zealand white rabbits were divided into the following three groups: the control group, the model group and the MSTN-induced group.

Prognosis after autologous peripheral blood stem cell transplantation for osteonecrosis of the femoral head in the pre-collapse stage: a retrospective cohort study.

Objectives: Autologous peripheral blood stem cell (auto-PBSC) transplantation is an effective therapeutic for the osteonecrosis of the femoral head (ONFH) but without prognosis estimation. This study mainly aimed to (1) determine whether auto-PBSC transplantation is a promising option, (2) assess the risk of hip-preservation failure, (3) achieve a predictive model of femoral head survival after the intervention, and (4) eventually identify clinical indications for auto-PBSC transplantation in future.

Methods: After reviewing the in-patient database of the First Affiliated Hospital of Zhejiang Chinese Medicine University from June 2012 to June 2014, 37 eligible patients with Association Research Circulation Osseous stage I or II ONFH who were receiving intra-arterial infusion of auto-PBSCs were recruited.

Bone turnover markers may predict the progression of osteonecrosis of the femoral head in aged males.

Background: Recent studies suggest that the imbalance of bone metabolism is associated with the pathogenesis of osteonecrosis of the femoral head (ONFH). However, limited data exist on the bone turnover markers (BTMs) in these patients compared with the healthy control (HC) comprehensively.

Methods: In total, 196 participants aged 29-83 [53 patients were excluded, 70 nontraumatic ONFH (mean age 57.

Peripheral Blood Stem Cell Therapy Does Not Improve Outcomes of Femoral Head Osteonecrosis With Cap-Shaped Separated Cartilage Defect.

A combination treatment with porous tantalum rod implantation and intra-arterial infusion of peripheral blood stem cells (PBSCs) provides a promise for treating early and intermediate stages of osteonecrosis of the femoral head (ONFH). However, its clinical indications and application restrictions remain unclear. This study aims to determine the clinical, histological, and radiological outcomes of a combination treatment using mechanical support and a targeted intra-arterial infusion of PBSCs for painful ONFH with a cap-shaped separation (CSS) cartilage defect.

[Research progress on clinical diagnosis and treatment for external snapping hip].

External snapping hip(ESH) is a vague term used to describe palpable or auditory snapping with hip movements with or without pain. The pathogenesis of ESH is related to the specific anatomical structure and friction factor. The clinical symptom is auditory snapping during activities, physical examination, X-ray, magnetic resonance imaging(MRI), dynamic ultrasound and other imaging techniques can be used to diagnose.
