Clinical effect of full endoscopic lumbar annulus fibrosus suture.

Purpose: The aim of this study was to investigate the clinical efficacy of full endoscopic lumbar annulus fibrosus suture in the treatment of single-segment lumbar disc herniation (LDH).

Methods: The clinical data of patients with single-segment LDH who underwent full endoscopic lumbar discectomy from January 2017 to January 2019 in our hospital were retrospectively analysed. Patients with full endoscopic lumbar discectomy combined with annulus fibrosus suture were divided into group A, and those with simple full endoscopic lumbar discectomy were divided into group B.

Management of floating hip injury: a review of the literature.

Aim: The aim of this study was to provide a comprehensive overview of floating hip injury and attempt to provide a management algorithm.

Methods: PubMed was searched using the terms 'Floating hip' or 'acetabular fracture' and 'Ipsilateral femoral fracture' or 'pelvic fracture' and 'Ipsilateral femoral fracture'. One author performed a preliminary review of the abstracts and references of the retrieved articles.

Poly-l-lactide-co-ε-caprolactone (PLCL) and poly-l-lactic acid (PLLA)/gelatin electrospun subacromial spacer improves extracellular matrix (ECM) deposition for the potential treatment of irreparable rotator cuff tears.

Biodegradable subacromial spacer implantation has become practicable for the treatment of irreparable rotator cuff tears (IRCT). However, the relative high degradation rate and inferior tissue regeneration properties of current subacromial spacer may lead to failure regards to long-term survival. It is reported that satisfactory clinical results lie in the surrounding extracellular matrix (ECM) deposition after implantation.

Hidden blood loss and its risk factors in percutaneous vertebroplasty surgery for osteoporotic vertebral compression fractures.

Objectives: Percutaneous vertebroplasty (PVP) is a percutaneous interventional procedure for osteoporotic vertebral compression fractures (OVCFs). However, hidden blood loss (HBL) during the surgery is easily disregarded. This study aimed to evaluate HBL and its possible risk factors in the patients following PVP for OVCFs.

EMT-related gene expression is positively correlated with immunity and may be derived from stromal cells in osteosarcoma.

Background: Osteosarcoma is the most common type of bone cancer in children and young adults. Recent studies have shown a correlation between epithelial-mesenchymal transition (EMT)-related gene expression and immunity in human cancers. Here, we investigated the relationship among EMT, immune activity, stromal activity and tumor purity in osteosarcoma.

Expression of the interleukin-21 and phosphorylated extracellular signal regulated kinase 1/2 in Kimura disease.

Objective: To investigate the expressions of interleukin (IL)-21 and phosphorylated extracellular signal regulated kinase 1/2 (pERK1/2) in Kimura disease (KD) and to correlate the findings with clinical and prognostic variables.

Methods: Immunohistochemical analysis of IL-21 and pERK1/2 was performed in 18 cases of KD and five gender- and age-matched control samples. Clinical data were extracted and patients followed up for a mean period of 32.
