[Early effect of induced membrane technique for the reconstruction of chronic osteomyelitis defects in limbs of adult patients].

Objective: To investigate the early clinical efficacy of induced membrane technique for reconstruction of large bone defects after debridement in adults with chronic osteomyelitis of limbs.

Methods: From March 2010 to March 2012,a total of 23 adult patients with chronic osteomyelitis of limbs were treated in our department. There were 15 males and 8 females, with a mean age 35.

A modified technique for fixation of chronic instability of the distal tibiofibular syndesmosis using a wire and button.

Distal tibiofibular syndesmosis injury accounts for 1% to 11% of soft tissue injuries of the ankle. Some acute syndesmotic injuries will fail to heal effectively owing to inadequate treatment or misdiagnosis, eventually resulting in chronic instability, which can destroy the stability of the ankle joint. Various surgical techniques have been described for fixation of the syndesmosis.

[Acutrak headless compression screw fixation for the treatment of scaphoid non-union].

Objective: To evaluate the early clinical and radiographic outcome of scaphoid non-unions treated with Acutrak headless compression screw.

Methods: From January 2008 to July 2011,21 patients with scaphoid non-union were treated in our department. There were 18 males and 3 females with a mean age of (23.

Use of pro-/synbiotics as prophylaxis in patients undergoing colorectal resection for cancer: a meta-analysis of randomized controlled trials.

Aims: To estimate the efficacy of pro-/synbiotics treatment in patients undergoing colorectal resection, a meta-analysis of randomized controlled trials was conducted.

Methods: An electronic search of PubMed, MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Academic Search Premier, and China National Knowledge Infrastructure was performed, and RevMan 5.0 was used for statistical analysis.

[Expression of cyclooxygenase-2 and vascular endothelial growth factor in human prostate cancer and its significance].

Objective: To evaluate expressions of cyclooxygenase-2 (COX-2) and vascular endothelial growth factor (VEGF) in primary prostate cancer and its clinical significance.

Methods: Expressions of COX-2 and VEGF were detected by immunohistochemical assay in tissues of 40 prostate cancer and 10 benign prostatic hyperplasia samples.

Results: COX-2 and VEGF levels in prostate cancer were much higher than those in BPH.
