[Establishment of 3D finite element model of meniscus and its mechanical analysis].

Objective: To establish a 3D finite element model of normal knee joint involved its meniscus, which can be used to simulate the anatomical morphology and characteristics of human knee joint, to verify the validity of the model by preliminary FEA mechanical analysis, and explain partially biomechanical mechanisms of meniscus.

Methods: CT and MRI data were harvested by scanning the knee joint of a healthy male volunteer, and then these data were imported into Mimics 10.01 software and Geomagic Studio software to constructed the 3D models of tissue structures of knee joint.

[Progress in finite element analysis of meniscus].

The meniscus biomechanics is one of the hottest areas in medical research. Finite element analysis(FEA) provides a new method for biomechanical studies. Using the FEA, the stress force and strain distribution characteristics of the normal meniscus can be analysed by establishing the finite element model of the meniscus and utilizing finite element softwares.

[Comparison of long Gamma 3 nail and proximal femur locking plate for the treatment of femoral subtrochanteric fractures].

Objective: To compare clinical efficacy of long Gamma 3 nail and proximal femur locking plate (PFLP) in treating femoral subtrochanteric fractures.

Methods: From January 2010 to January 2017, clinical data of 58 patients with subtrochanteric fractures followed more than 12 months were retrospective analyzed. Among them, 35 patients were treated with long Gamma 3 nail including 18 males and 17 females aged from 25 to 78 years old with an average of(66.

[Advanced progress on the treatment of anterior approach to the thoracolumbar vertebral fractures].

Thoracolumbar fractures are common and severe traumas. Anterior approaches can achieve adirect spinal cord decompression and reconstruct anterior column height what load bearing the major load distribution of the spine. Therefore, anterior approach is an important method in the treatment of thoracolumbar fractures.

Controlled study on Gamma nail and proximal femoral locking plate for unstable intertrochanteric femoral fractures with broken lateral wall.

The gamma nail and proximal femoral locking plate (PFLP) are both used for fractures. A controlled study was performed to determine the optimal implant. To assess and analyze the clinical effects of gamma nails and PFLPs for patients with unstable intertrochanteric femoral fractures, specifically with broken lateral walls.

[Inversive LISS plate in treating intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures].

Objective: To study clinical effects of inversive LISS(less invasive stabilization system, LISS) plate for the treatment of intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures.

Methods: From January 2012 to January 2015, 24 patients with intertrochanteric and subtrochanteric fractures combined with femoral shaft fractures were treated with inversive LISS plate, included 16 males and 8 females with an average age of 62.5 years old ranged from 35 to 81 years old.

[A medium term therapeutic effects of anatomic locking plate for femoral intertrochanteric with lateral femoral wall fractures].

Objective: To retrospectively study medium term follow-up outcomes of the femoral intertrochanteric with lateral femoral wall fractures using anatomic locking plate fixation.

Methods: From June 2010 to January 2013, 18 cases of the unstable femoral intertrochanteric with lateral femoral wall fractures were treated with the anatomic locking plate, included 8 males and 10 females with an average age of 75.5 years ranging from 19 to 83 years old.

Mechanisms underlying the antiapoptotic and anti-inflammatory effects of monotropein in hydrogen peroxide-treated osteoblasts.

Monotropein, the primary iridoid glycoside isolated from Morindacitrifolia, has been previously reported to possess potent antioxidant and antiosteoporotic properties. However, there is no direct evidence correlating the antiosteoporotic effect of monotropein with its observed antioxidant capacity, and the molecular mechanisms involved in mediating these processes remain unclear. Therefore, the aim of the present study was to investigate the protective effects of monotropein against oxidative stress in osteoblasts and the mechanisms involved in mediating this process.

[Comparison of anatomical locking plate and Gamma nail for the treatment of intertrochanteric fracture with external wall fractures].

Objective: To compare clinical efficacy of anatomic locking plate and Gamma nail in treating unstable femoral intertrochanteric fractures with external wall fractures.

Methods: From June 2010 to June 2014,clinical data of 44 patients with intertroehanteric fractures associated with lateral wall fractures (type 31A2.2-3.

Curculigoside regulates proliferation, differentiation, and pro-inflammatory cytokines levels in dexamethasone-induced rat calvarial osteoblasts.

Background: Curculigoside (CCG), one of the main bioactive phenolic compounds isolated from the rhizome of Curculigo orchioides Gaertn., is reported to prevent bone loss in ovariectomized rats. However, the underlying molecular mechanisms are largely unknown.
