Logistic regression analysis of drug compliance and influencing factors in elderly osteoporosis patients.

A cross-sectional study was conducted to understand the medication compliance of elderly osteoporosis patients and to further analyze the influencing factors of drug compliance. The elderly osteoporosis patients who were admitted to the First People's Hospital of Huzhou, Zhejiang from March 2015 to January 2017 were selected as the research subjects. Subsequently, the three months, six months and 12 months of follow-up were performed from the group of subjects who prescribe anti-osteoporosis drugs to determine the patient's medication status.

[Intercondylar fossa screw with plate fixation for Letenneur type III Hoffa fractures].

Objective: To investigate clinical effect of intercondylar fossa screw with plate fixation in treating Letenneur type III Hoffa fractures.

Methods: From March 2005 to December 2014, 7 patients with Letenneur type III Hoffa fracture were treated by intercondylar fossa screw with plate fixation, including 5 males and 2 females aged from 27 to 68 years old with an average of 42.6 years old.

A comparison of the clinical effect of two fixation methods on Hoffa fractures.

Introduction: Hoffa fractures are rare and difficult to treat for orthopaedic surgeons. The mechanism of injury of Hoffa fracture is still unknown and the operation approch and fixation method are still controversial. The aim of this study is to compare the clinical effect between two fixation methods on Hoffa fractures.

Levels of metalloproteinase (MMP-3, MMP-9), NF-kappaB ligand (RANKL), and nitric oxide (NO) in peripheral blood of osteoarthritis (OA) patients.

Background: The aim of this study was to judge whether there is a correlation between some biochemical features of knee osteoarthritic blood and clinical characteristics and to evaluate the potential relationship between osteoarthitis (OA) severity and putative biomarkers for the disease.

Methods: 105 patients suffering from knee OA were analyzed clinically (Lequesne's index) and radiographically (Kellgren and Lawrence, K&L). Plasma and peripheral blood mononuclear cells (PBMC) were harvested separately.
