Background: Participants with prediabetes are at a high risk of developing type 2 diabetes (T2D). Recent studies have suggested that blocking the receptor activator of nuclear factor-κB ligand (RANKL) may improve glucose metabolism and delay the development of T2D. However, the effect of denosumab, a fully human monoclonal antibody that inhibits RANKL, on glycemic parameters in the prediabetes population is uncertain.

Background: The prognostic nutritional index (PNI) has been proposed as a useful prognostic tool in multiple populations. However, its prognostic value has not been fully evaluated in the hip fracture population. We aimed to assess the relationship between PNI and postoperative complications as well as 2-year all-cause mortality in the hip fracture population.

Purpose: To evaluate the impact of preoperative anemia on postoperative complications after hip fracture surgery.

Patients And Methods: We conducted a retrospective study including hip fracture patients at a teaching hospital between 2005 and 2022. We defined preoperative anemia as the last hemoglobin measurement level before surgery < 130 g/L for men and < 120 g/L for women.

Background: At present, there are several diagnostic criteria of sarcopenia were used in China, and the diagnostic criteria were not unified. This study aims to investigate the consistency between the latest sarcopenia diagnostic criteria Asian Working Group for Sarcopenia(AWGS 2019) and other common diagnostic criteria. The changes of muscle mass, muscle strength and physical function with age and their effects on the diagnosis of sarcopenia were also analyzed.

Background: Chronic gastritis (CG) is a common digestive disease with the highest morbidity among multiple digestive diseases, which seriously lowers the life quality of patients. The pathological alternations of gastric mucosa, and its possible mechanisms have been the focus of CG-related researches. Accumulative basic and clinical evidence has confirmed that ultraviolet C (UVC) is effective in relieving superficial acute infective inflammation, skin and mucous membrane injuries, and ulcers, and promoting wound healing.

When congenital melanocytic nevus (CMN) is in the maxillofacial region, a safer, more effective and fewer side-effects treatment is needed for patients with high requirement for appearance. The objective of this study was to investigate the effectiveness of radiofrequency thermal ablation (RFA) for CMN in the maxillofacial region. We reviewed 21 patients treated with RFA for CMN followed by a blinded retrospective analysis of serial photographs taken during the course of their therapy.

Confusion persists over pathogenesis of spondylolysis. To confirm pathogenicity of the previously identified causative mutation of spondylolysis and investigate the genetic etiology, we generate a new mouse line harboring D673V mutation in the Slc26a2 gene. D673V mutation induces delayed endochondral ossification characterized by transiently reduced chondrocyte proliferation in mice at the early postnatal stage.

Background: Mutations in the SLC26A2 gene cause a spectrum of currently incurable human chondrodysplasias. However, genotype-phenotype relationships of SLC26A2-deficient chondrodysplasias are still perplexing and thus stunt therapeutic development.

Methods: To investigate the causative role of SLC26A2 deficiency in chondrodysplasias and confirm its skeleton-specific pathology, we generated and analyzed slc26a2 and Col2a1-Cre; slc26a2 mice.

A fracture is the most dangerous complication of osteoporosis in patients because the associated disability and mortality rates are high. Osteoporosis impairs fracture healing and prognosis, but how intramembranous ossification (IO) or endochondral ossification (EO) during fracture healing are affected and whether these two kinds of ossification are different between glucocorticoid-induced osteoporosis (GIOP) and estrogen deficiency-induced osteoporosis (EDOP) are poorly understood. In this study, we established two bone repair models that exhibited repair via IO or EO and compared the pathological progress of each under GIOP and EDOP.

Aging drives the accumulation of senescent cells (SnCs) including stem/progenitor cells in bone marrow, which contributes to aging-related bone degenerative pathologies. Local elimination of SnCs has been shown as potential treatment for degenerative diseases. As LepR mesenchymal stem/progenitor cells (MSPCs) in bone marrow are the major population for forming bone/cartilage and maintaining HSCs niche, whether local elimination of senescent LepR MSPCs delays aging-related pathologies and improves local microenvironment need to be well defined.

Postmenopausal osteoporosis is one of the most prominent worldwide public health problems and the morbidity is increasing with the aging population. It has been demonstrated that early diagnosis and intervention delay the disease progression and improve the outcome. Therefore, searching for biomarkers that are able to identify postmenopausal women at high risk for developing osteoporosis is an effective way to improve the quality of life of patients, and alleviate social and economic burdens.
