Protection of Icariin Against Hydrogen Peroxide-Induced MC3T3-E1 Cell Oxidative Damage.

Objective: The aim of the present study was to evaluate the potential protective mechanism of icariin against oxidative damage caused by hydrogen peroxide in MC3T3-E1 cells.

Methods: MC3T3-E1 cells were treated with different concentrations of icariin to explore the optimal dose of icariin. MC3T3-E1 cells were divided into groups treated with various concentrations of hydrogen peroxide (H O ; 0, 0.

[Comparative study on the treatment of acromioclavicular joint dislocation: coracoclavicular ligament reconstruction combined with hook plate fixation or suture-anchor fixation].

Objective: To investigate the clinical outcomes of acromioclavicula (AC) joint dislocation treated with coracoclavicular (CC) ligament reconstruction and hook plate fixation/suture-anchor fixation.

Methods: There were 105 patients with Rockwood type III or severer AC joint dislocations were randomly divided into two groups from February 2007 to April 2010. They were treated with CC ligament reconstruction using double bundle of Palmaris longus (hook plate fixation group, 54 cases), and subsequently fixed with hook plates or suture-anchors (suture-anchors group, 51 cases).
