How does the position of the pelvis and femur influence the selection of prosthesis size during 2D preoperative planning for total hip arthroplasty?

Purpose: Total Hip Arthroplasty (THA) is the primary treatment for hip diseases today. Nevertheless, total hip arthroplasty has its challenges, and one of these challenges is the potential for incorrect execution of the preoperative planning process. Such errors can lead to complications such as loosening and instability of the prosthesis and leg length discrepancy.

Omega-3 polyunsaturated fatty acids alleviate endoplasmic reticulum stress-induced neuroinflammation by protecting against traumatic spinal cord injury through the histone deacetylase 3/ peroxisome proliferator-activated receptor-γ coactivator pathway.

Omega-3 polyunsaturated fatty acids (ω-3 PUFAs) attenuate inflammatory responses in the central nervous system, leading to neuroprotective effects. Inhibition of histone deacetylase 3 (HDAC3) has neuroprotective effects after spinal cord injury (SCI) through the SIRT1 pathway, but the pathophysiological mechanisms of SCI are complex and the interactions between ω-3 PUFAs and organelles remain largely unknown. This study aimed to investigate the effect of ω-3 PUFAs on endoplasmic reticulum (ER) stress-induced neuroinflammation through the HDAC3/peroxisome proliferator-activated receptor-γ coactivator (PGC)-1ɑ pathway after SCI.

Does the use of intraoperative measurement reduce limb length discrepancies after total hip arthroplasty?

Purpose: Postoperative limb length discrepancy (LLD) is a common complication of total hip arthroplasty, and several methods exist to prevent LLD, but each has its benefits and drawbacks. The study investigates the application of intraoperative lower limb length measurement in preventing postoperative LLD.

Methods: This study retrospectively analyzed 70 patients who underwent total hip arthroplasty from October 2018 to July 2022.

FNDC3B circular RNA promotes the migration and invasion of gastric cancer cells via the regulation of E-cadherin and CD44 expression.

Circular RNAs (circRNAs) are a new class of RNAs, and many studies have identified thousands of circRNAs in tumor cells. Fibronectin type III domain-containing protein 3B (FNDC3B) circular RNA (circFNDC3B, circBase ID: hsa_circ_0006156) circularizes with exons 5 and 6. Gibson Assembly DNA technology was used to construct a circFNDC3B expression vector without a splice site and restriction enzyme site.

[Case-control study on suture-assisted locking plate for the treatment of proximal humeral fractures in elderly].

Objective: To explore clinical effects of suturing-assisted locking plate in treating elderly proximal humeral fractures.

Methods: From January 2005 to January 2013, 55 elderly patients with three- and four-part fractures of proximal humeral fractures were divided into treatment group and control group. In treatment group, there were 31 patients including 12 males, and 19 females aged from 65 to 85 with an average of (74.
