Objective: Although benzene is a confirmed environmental carcinogen, the mechanism of its carcinogenicity remains largely unclear. The suggested oncogene, miR-221, is elevated and plays important roles in various tumors, but its role in benzene-induced carcinogenesis remains unknown.
Methods: In the present study, we constructed hydroquinone (HQ, a representative metabolite of benzene with biological activity)-transformed malignant cell line (16HBE-t) and analyzed the level of miR-221 in it with qRT-PCR.
Purpose: We aimed to determine the global effects of the Chêneau brace combined with Schroth exercises on adolescent idiopathic scoliosis (AIS).
Methods: We analyzed 192 patients with AIS who underwent the Chêneau brace treatment alone or combined with Schroth best practice (SBP) from June 2013 to October 2019. There were 138 patients in the Brace group and 54 patients in the Brace + SBP group.
Purpose: To establish a classification system for the different types of posterior tibial plateau fractures (PTPF), and to explore the fracture patterns and early results of treatment.
Methods: 39 PTPFs patients who received surgeries through posteromedial or (and) posterolateral knee approaches were analyzed retrospectively.
Results: There were 5 types of PTPFs identified in the new classification system: posteromedial split fracture (type I, 7 patients), posterolateral split fracture (type II, 5 patients), posterolateral depression fracture (type III, 11 patients), posterolateral split and depression fracture (type IV, 2 patients), and posteromedial split combined with posterolateral depression fracture (type V, 14 patients).
Objective: To compare clinical effects between Pavlik harness and Bryant traction in treating femoral shaft fractures in infants,including the time of hospitalization, expense of treatment, complications,time of bone union.
Methods: From May 2005 to August 2010,the clinical data of 42 infants with femoral shaft fractures were retrospectively analyzed. Among the patients, 23 cases were treated with Pavlik harness(Pavlik harness group),there were 14 males and 9 females,ranging in age from 1 to 12 months with an average of (5.
A biomechanical study on the interosseous membrane and radial head in cadaveric forearms.
Acta Orthop Traumatol Turc
October 2013
Objective: Our aim was to evaluate the biomechanical properties of the interosseous membrane (IOM) and radial head and investigate the pathomechanics of the Essex-Lopresti injury.
Methods: Twelve adult fresh frozen upper limbs of human cadavers were chosen for test. First, the 12 intact specimens were mounted onto a materials testing machine to carry out biomechanical tests in pronation, supination and neutral positions, respectively.
Objective: The aim of this study is to compare the clinical effects of percutaneous reconstruction plate and percutaneous sacroiliac screws in treatment of unstable posterior pelvic ring fracture.
Methods: Fifty-eight patients with unstable posterior pelvic ring fracture treated with two methods from March 2002 to October 2007 were enrolled in the study and divided into two groups according to two kinds of internal fixation: percutaneous reconstruction plate (20 males and 9 females, at mean age 37.3 ± 11.
Objective: To study the anatomical and biomechanical features of the interosseous membrane (IOM) of the cadaveric forearm.
Methods: Ten radius-IOM-ulna structures were harvested from fresh-frozen cadavers to measure the length, width and thickness of the tendinous portion of IOM. Then, the tendinous portion was isolated along with the ulnar and radial ends to which the tendon attached after measurement.
