The aim of the present study was to compare the efficacy and complications of two fixation techniques, namely dynamic hip screw (DHS) and proximal femoral nail antirotation (PFNA), in the treatment of osteoporotic femoral intertrochanteric fracture in elderly patients, and to detect changes in transforming growth factor β2 (TGF-β2) expression in the two groups. A total of 100 elderly patients with femoral intertrochanteric fracture were randomly divided into two groups that were treated with either DHS or PFNA. Peri-operative complications were observed in the patients and ELISA was used to detect TGF-β2 expression levels at 1, 7, 15 and 30 days after surgical treatment. The clinical efficacy and the incidence rate of complications at 3 months after the operation were compared. In comparison with the DHS group, the PFNA group had a shorter operation time, a lower bleeding volume and a shorter post-operative weight-bearing time. The contents of TGF-β2 in the two groups at 7 days after the operation were higher than those at 1 day, reached a peak at 15 days and had gradually decreased again at 30 days after the operation. The contents of TGF-β2 at 1, 7 and 15 days in the PFNA group were higher than those at the identical time-points in the DHS group (P<0.01). Regarding the clinical efficacy in the two groups at 3 months of post-surgery, the rate of excellent/good efficacy in the PFNA fixation group (90.0%) was higher than that in the DHS fixation group (74.0%). Of note, PFNA fixation had a higher clinical efficacy, a shorter operation time, less intra-operative trauma, a relatively faster fracture healing process and fewer complications in comparison with DHS fixation, and is therefore more suitable for treating osteoporotic femoral intertrochanteric fracture in the elderly. PFNA fixation is superior to DHS fixation, which may be associated with the higher level of TGF-β2 expression in comparison with that in the DHS group.

Background: Neuronal cholesterol deficiency may contribute to the synaptopathy observed in Alzheimer's disease (AD). However, the underlying mechanisms remain poorly understood. Intact synaptic vesicle (SV) mobility is crucial for normal synaptic function, whereas disrupted SV mobility can trigger the synaptopathy associated with AD.

Background: It has been reported the therapeutic effects of mesenchymal stem cells (MSCs) on hearing loss. This study explored the therapeutic effects of growth differentiation factor 6 (GDF6) overexpression-induced MSCs (MSCs-GDF6) on age-related hearing loss (ARHL) and its underlying mechanisms.
Methods: Reverse transcription-quantitative PCR and western blotting were used to evaluate gene expression.

Department of Cardiothoracic Surgery, The Affiliated Jiangyin Hospital of Nantong University, 214400 Jiangyin, Jiangsu, China.
Background: This study investigates the role of small ubiquitin-like modifier (SUMO)-specific peptidase 5 (SENP5), a key regulator of SUMOylation, in esophageal squamous cell carcinoma (ESCC), a lethal disease, and its underlying molecular mechanisms.
Methods: Differentially expressed genes between ESCC mouse oesophageal cancer tissues and normal tissues were analysed via RNA-seq; among them, SENP5 expression was upregulated, and this gene was selected for further analysis. Immunohistochemistry and western blotting were then used to validate the increased protein level of SENP5 in both mouse and human ESCC samples.

Background: Thyroid Hormones (THs) critically impact human cancer. Although endowed with both tumor-promoting and inhibiting effects in different cancer types, excess of THs has been linked to enhanced tumor growth and progression. Breast cancer depends on the interaction between bulk tumor cells and the surrounding microenvironment in which mesenchymal stem cells (MSCs) exert powerful pro-tumorigenic activities.

Background: Diabetes mellitus is associated with morphological and functional impairment of the heart primarily due to lipid toxicity caused by increased fatty acid metabolism. Extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) have been implicated in the metabolism of fatty acids in the liver and skeletal muscles. However, their role in the heart in diabetes remains unclear.
