Ginkgetin attenuates bone loss in OVX mice by inhibiting the NF-κB/IκBα signaling pathway.

Background: Osteoporosis is a disease associated with bone resorption, characterized primarily by the excessive activation of osteoclasts. Ginkgetin is a compound purified from natural ginkgo leaves which has various biological properties, including anti-inflammation, antioxidant, and anti-tumor effects. This study investigated the bone-protective effects of ginkgetin in ovariectomized (OVX) mice and explored their potential signaling pathway in inhibiting osteoclastogenesis in a mouse model of osteoporosis.

TREATMENT OF THORACOLUMBAR FRACTURES BY CLOSED REDUCTION VIA A PERCUTANEOUS SOLID PEDICLE SCREW.

Objectives: Investigate the effect of closed reduction and per- cutaneous pedicle screw fixation in treating thoracolumbar fractures.

Methods: This retrospective study analyzed 12 cases of single-segment thoracolumbar spine fractures without spinal cord and nerve injury at our department from March 2016 to September 2017. Patients were treated with closed reduction, percutaneous reduction, and internal fixation with solid pedicle screws.

Comparison of the technique of anterior cervical distraction and screw elevating-pulling reduction and conventional anterior cervical reduction technique for traumatic cervical spine fractures and dislocations.

Introduction: To analyze and confirm the advantages of anterior cervical distraction and screw elevating-pulling reduction which are absent in conventional anterior cervical reduction for traumatic cervical spine fractures and dislocations.

Materials And Methods: A retrospective study was conducted on 86 patients with traumatic cervical spine fractures and dislocations who received one-stage anterior approach treatment for a distraction-flexion injury with bilateral locked facet joints between January 2010 and June 2015. They were 54 males and 32 females with an age ranging from 20 to 73 years (average age, 40.

[The causes of death and risk factors in patients of war wound and trauma of extremities by logistic regression model].

Objective: To explore the causes of death and risk factors in patients of war wound and trauma of extremities.

Methods: This retrospective study involved 352 patients of war wound and trauma of extremities admitted to 303rd Hospital of People's Liberation Army during the period between 1968 to 2002. All the data were reviewed and the causes of death of 15 patients were analyzed by autopsy, and a computer's logistic regression model analysis was performed to approach the risk factors of death.

[Serial thin cross-sectional anatomy and computerized three-dimensional reconstruction of metacarpal fascial spaces of hand].

Objective: To build three-dimensional (3-D) visible model for surgical treatment of infection of fascial spaces of hand.

Methods: Serial thin cross-sections (0.2 mm) of hand were made by cryomicrotome, and the thin cross-sections of metacarpal parts were observed.
