Experimental study on Fenton oxidation regeneration of adsorbed toluene saturated activated carbon.

In this study, Fenton reagent has been adopted to oxidize and regenerate the resin based spherical activated carbon (SAC) adsorbed with toluene saturation. The effects of the mole ratio of Fe and HO, the dosage of HO, pH value, temperature, regeneration time and the like on the regeneration rate of activated carbon have been exploited, the adsorbent used in the experiment is spherical activated carbon with a maximum adsorption capacity of 512.25 mg/g produced by Cui hong Taiyuan Science and Technology Co.

Self-designed femoral neck guide pin locator for femoral neck fractures.

Closed reduction and fixation with 3 cannulated screws is a widely accepted surgery for the treatment of femoral neck fractures. However, how to obtain optimal screw placement remains unclear. In the current study, the authors designed a guide pin positioning system for femoral neck fracture cannulated screw fixation and examined its application value by comparing it with freehand guide needle positioning and with general guide pin locator positioning provided by equipment manufacturers.

Open reduction and internal fixation with conventional plate via L-shaped lateral approach versus internal fixation with percutaneous plate via a sinus tarsi approach for calcaneal fractures - a randomized controlled trial.

Objective: We aimed to compare the clinical outcomes of intra-articular calcaneus fractures treated with open reduction and internal fixation with conventional plate via L-shaped lateral approach (routine treatment) versus those with percutaneous plate via a sinus tarsi approach (minimally invasive treatment).

Methods: One hundred and seventeen displaced intra-articular calcaneal fractures in 108 patients from January 2007 and September 2010 were randomly allocated to receive routine treatment (49 patients) or minimally invasive treatment (59 patients). Operative time, preoperative and postoperative calcaneal height, width, length, Böhlers angle, Gissanes angle, and incision healing were recorded.

A minimally invasive sinus tarsi approach with percutaneous plate and screw fixation for intra-articular calcaneal fractures.

According to characteristic of anatomical structure of calcaneus and sinus tarsi approach, the minimally invasive plate for treatment of displaced intra-articular calcaneal fractures had been designed. Here we aimed to review the effect of this treatment. Forty intra-articular calcaneal fractures in 38 patients from September 2006 to September 2008 were treated with percutaneous plate via sinus tarsi approach under the monitoring of C-shaped arms.
