Clinical outcomes of an olive wire and external fixator versus a metallic screw in the treatment of inferior tibiofibular syndesmosis injuries in ankle fractures.

Background: Metal screws are the most widely used in treating syndesmotic injuries, but failure and the rigidity of the screws can threaten the success of the treatment and increase the cost of care. We have provided an alternative with an olive wire and external fixator(OWEF) used for syndesmotic fixation.

Methods: A retrospective longitudinal follow-up study was conducted.

Association between XRCC1 Arg399Gln polymorphism and glioma risk in a Chinese population: a case-control study.

Aim: In China, the incidence rates of glioma tend to be increased, however, the genetic contribution to its etiology is not well-understood. The aim of this study is to evaluate the association of XRCC1 Arg399Gln polymorphism with glioma risk in a Chinese population.

Materials And Methods: We conducted a case-control study on 387 patients with glioma and 400 cancer-free controls between 2004 and 2014.

Clinical characteristics and neurologic recovery of patients with cervical spinal tuberculosis: should conservative treatment be preferred? A retrospective follow-up study of 115 cases.

Objective: To present the clinical characteristics and prognostic factors of neurologic recovery in patients with cervical spinal tuberculosis (CST).

Methods: General description and multivariate analysis were used to detect possible predictors of the outcome of patients with neurologic deficit. Follow-up data were used to generate a Kaplan-Meier curve of neurologic recovery.

[Neuroendoscope-assisted surgical treatment of spinal dural arteriovenous fistulas].

Objective: To study the utility of neuroendoscope-assisted surgery in the treatment of spinal dural arteriovenous fistulas.

Methods: From November 2008 to November 2010, 8 cases of spinal dural arteriovenous fistulas underwent neuroendoscope-assisted surgical treatment by a hemilaminectomy approach. Retrospective analyses were performed for their clinical manifestations, imaging findings, surgical approaches, postoperative recovery and follow-up profiles.

[The methylation analysis of EMP3 and PCDH-gamma-A11 gene in human glioma].

Objectives: To study the relationship between promoter methylation and mRNA expressions of EMP3 and PCDH-gamma-A11 genes in human glioma, and to analyze the regulation mechanism of promoter methylation in the progression of glioma.

Methods: The promoter methylation of EMP3 and PCDH-gamma-A11 was studied by a methylation specific PCR in 88 primary astrocytoma, 10 normal brain tissues and 2 glioma cell lines. The mRNA expressions were detected by real-time PCR in 30 primary glioma and 10 normal brain tissues.

Number concentration and size distributions of submicron particles in jinan urban area: characteristics in summer and winter.

The aerosol number concentration and size distribution were measured with the newly developed Wide-range Particle Spectrometer in summer and winter of 2006 at the urban site of Jinan City. Here reported the characteristics of fine particles of the different observation seasons. Relative high number concentrations for the particles in the diameter range of 10-500 nm were observed in both seasons.

[The methylation and mRNA expression of SLC5A8 and TMS1/ASC genes in human glioma].

Objective: To study the methylation status of the SLC5A8 and TMS1/ASC genes, candidate tumor-inhibiting genes closely related to the central nervous system, in the promoter regions, the mRNA expression of these 2 genes, and their correlation with the clinical characteristics in human glioma.

Methods: The methylation status of SLC5A8 and TMS1/ASC genes in the promoter regions was studied by methylation specific PCR (MSP) in the specimens of primary astrocytoma from 88 patients, 55 males and 33 females, aged 12 - 81, and 10 specimens of normal brain tissue, all obtained during operation, and in the human glioma cells of the lines U251 and SHG-44. The mRNA expression levels of SLC5A8 and TMS1/ASC genes in 30 specimens of primary glioma and 10 specimens of normal brain tissue were determined by conventional RT-PCR and real-time PCR.

Traumatic subdural hydroma developing into chronic subdural hematoma.

Objective: To probe the incidence, pathogenesis and clinical characteristics of traumatic subdural hydroma (TSH) developing into chronic subdural hematoma (CSDH).

Methods: We retrospectively analyzed the clinical data of 32 patients with TSH developing into CSDH and reviewed related literature.

Results: 16.
