ReviewSystematic reviews on reports of hip fractures in Web of Science: a bibliometric analysis of publication activity.
The objective of this study was to analyze the trend in the publication of systematic reviews on hip fractures through a bibliometric approach. ⋯ The best evidence in the field of hip fractures has attracted increasing attention. Systematic reviews on hip fractures from China have been increasingly more frequent during the past 6 years, particularly in 2012.

Case ReportsComparisons in finite element analysis of minimally invasive, locking, and non-locking plates systems used in treating calcaneal fractures of Sanders type II and type III.
Calcaneal fractures are relatively common but complex, while the treatment of these fractures is still controversial. The objective of this study was to compare the biomechanical stability of minimally invasive, locking, and non-locking plating systems used for fixing Sanders type II and type III calcaneal fractures. Finite element analysis was used for comparing the three types of plating systems. This study helped in guiding the clinical management of calcaneal fractures. ⋯ The minimally invasive plating method could be a better alternative method in treating Sanders type II and type III calcaneal fractures. The observed stiffness of locking plate was not obviously stronger than unlocked plate.

Protectin D1 promotes resolution of inflammation in a murine model of lipopolysaccharide-induced acute lung injury via enhancing neutrophil apoptosis.
Protectin D1 (PD1), derived from docosahexaenoic acid, has been shown to control and resolve inflammation in some experimental models of inflammatory disorders. We investigated the protective roles of protectin D1 in pulmonary inflammation and lung injury induced by lipopolysaccharide (LPS). ⋯ Posttreatment with PD1 enhances resolution of lung inflammation during LPS-induced acute lung injury by enhancing apoptosis in emigrated neutrophils, which is, at least in part, caspase-dependent.

Local treatment of osteoporosis with alendronate-loaded calcium phosphate cement.
A new treatment strategy is to target specific areas of the skeletal system that are prone to clinically significant osteoporotic fractures. We term this strategy as the "local treatment of osteoporosis". The study was performed to investigate the effect of alendronate-loaded calcium phosphate cement (CPC) as a novel drug delivery system for local treatment of osteoorosis. ⋯ The ALE-loaded CPC displayed satisfactory properties in vitro, which can reverse the OVX rat vertebral trabecular bone microarchitecture and biomechanical properties in vivo.
