Comparison of the therapeutic efficacy of hip arthroplasty and proximal femoral nail antirotation internal fixation for unstable intertrochanteric femur fractures.

Objective: To compare the therapeutic efficacy of total hip arthroplasty (THA) versus proximal femoral nail antirotation (PFNA) internal fixation for treating unstable intertrochanteric femur fractures (UIFF).

Methods: In this retrospective study, the clinical data of 86 patients with intertrochanteric femur fractures (IFF) treated in Hangzhou Fuyang Hospital of Orthopedics of Traditional Chinese Medicine from January 2022 to December 2023 were collected and analyzed. Patients were categorized into two groups based on their treatment modality: the THA group (n=45, treated with THA) and the PFNA group (n=41, treated with PFNA internal fixation).

Ceramifiable Silicone Rubber Composites with Enhanced Self-Supporting and Ceramifiable Properties.

Ceramifiable silicone rubber (SR) composites with excellent self-supporting properties and ceramifiable properties were prepared by incorporating silicate glass frits (SGFs) and sodium tripolyphosphate (STPP) into the SR. Ceramic residues were obtained by firing ceramifiable SR composites at 700, 850, and 1000 °C for 30 min. The bending angles of the composites were tested for evaluating the self-supporting property.

[Effect and mechanism of total flavone of epimedium on primary callus formation in ovariectomized rats with fractures].

Objective: To explore the effects and related mechanisms of total flavone of epimedium treatment(TFE)on primary callus for mation in ovariectomized rats.

Methods: Forty male SD rats weighted from 209 to 246 g and aged 6 to 8 weeks were selected. Six weeks after ovariectomy a femur fracture model with middiaphyseal segment fracture was established, estimated and randomly divided into TFE group (150 mg·kg⁻¹·d⁻¹) and control group(received saline).

Intravenous Zoledronic Acid 5 mg on Bone Turnover Markers and Bone Mineral Density in East China Subjects with Newly Diagnosed Osteoporosis: A 24-month Clinical Study.

Objective: This randomized, double-blind, placebo-controlled study assessed the necessity of early intervention, safety and efficacy of intravenous zoledronic acid 5 mg/year in East China women with newly diagnosed osteoporosis at high risk of fracture during a 24-month treatment period.

Methods: Subjects (57 [52-62] years old) were randomized 3:2 to zoledronic acid versus placebo (randomized at baseline, zoledronic acid [175 cases], placebo-zoledronic acid [110 cases]). The bone mineral density of the lumbar spine and total hip was measured every 6 months with the use of dual-energy X-ray absorptiometry.

Identification of human serum protein targets of Qianggu Decoction () in primary type I osteoporosis based on tandem mass tag labeling and liquid chromatography-tandem mass spectrometry technology.

Objective: To investigate the serum protein targets of Qianggu Decoction (, QGD) on treating osteoporosis by the proteomics analysis using tandem mass tag (TMT) and liquid chromatographytandem mass spectrometry (LC-MS/MS).

Methods: Twenty serum protein samples were recruited (10 patients with primary type I osteoporosis before and after QGD treatment) and the high abundance ratios protein was removed, two serum samples were extracted and labeled with TMT reagent. Then, mass spectrometric detection, identification of differentially expressed proteins and bioinformatics analysis of differentially expressed proteins were carried out.
