In clinical practice, the minimally invasive approach combined with an anatomical locking plate has been used to treat scapular body fractures. In addition, we have made minor modifications to the minimally invasive approach.

This study aimed to compare the stability of the new titanium anatomic and traditional titanium reconstructive plates for extra-articular scapular fractures through finite element analysis.
Methods: Two models of scapular assembly were constructed, including one anatomic plate (AP model) and one reconstructive plate (RP model).
Hepatocellular carcinoma (HCC) is a malignant tumor with a highly aggressive and metastatic nature. Ultrasound remains a routine monitoring tool for screening, treatment and post-treatment recheck of HCC. Therefore, it is of great significance to explore the role of ultrasound therapy and related genes in prognosis prediction and clinical diagnosis and treatment of HCC.

This study aimed to compare the therapeutic efficacy of titanium anatomic and reconstructive plates for extra-articular fractures of the scapula (Miller types IIb, IIc, and IV).
Methods: A retrospective study of 41 patients who underwent treatment for extra-articular fractures of the scapula between March 2017 and March 2020 was conducted.
Background: Mesoporous Bioactive Glass (MBG) has been widely studied because of its excellent histocompatibility and degradability. However, due to the lack of good osteoinductive activity, the pure MBG scaffold is not effective in repairing large-scale bone defects.
Objective: To observe the repair effect of MBG scaffolds delivering Salvianolic acid B (SB) on critical bone defects in rats.
The treatment goal for spinal cord injury (SCI) is to repair neurites and suppress cellular apoptosis. This study is to investigate the effects of nuclear heme oxidase-1 (HO-1) on the acute spinal cord injury and the related mechanisms. The rat model of the SCI was established.

Objective To detect the effects of microRNA 125a-5p (miR-125a-5p) in heme oxygenase 1 (HO-1) truncation (HO-1Cδ23) regulating the blood-spinal barrier (BSCB) after hypoxic injury. Methods HCMEC/D3 and astrocytes were co-cultured in Transwell chamber to establish BSCB model in vitro, and then prepared with cobalt chloride to establish BSCB hypoxic injury model. The experiment was divided into blank group, non-virus loading group, HO-1Cδ23 group (Lv-HO-1Cδ23), miRNA negative control group (Lv-HO-1Cδ23 combined with miR-NC treatment), miRNA mimic group (Lv-HO-1Cδ23 combined with miR-125a-5p mimics treatment) and miRNA inhibitor group (Lv-HO-1Cδ23 combined with miR-125a-5p inhibitor treatment).

MicroRNA-429(miR-429) plays an important role in mesenchymal stem cells. Hypoxia-inducible factor 1α (HIF-1α) is a nuclear transcription factor that regulates the proliferation, apoptosis and tolerance to hypoxia of mesenchymal stem cells. HIF-1α is also a target gene of miR-429.

After injury, BSCB damage results in increasing capillary permeability and release of inflammatory factors. Recent studies have reported that haem oxygenase-1 (HO-1) fragments lacking 23 amino acids at the C-terminus (HO-1C[INCREMENT]23) exert novel anti-inflammatory and antioxidative effects in vitro.

However, the underlying mechanisms were not elucidated. The purpose of this study was to investigate the underlying mechanisms by which Netrin-1 promotes autophagy and improves functional recovery after SCI.
