[Biomechanical study on femoroplasty-augmentation for prevention of osteoporotic hip fractures].

Objective: To explore whether femoral plasty can improve the fracture resistance of osteoporotic femoral specimens and prevent hip fracture, and to compare the difference of mechanical strength changes between two different femoral plasty methods in osteoporotic femoral specimens, so as to determine the best strengthening area of the plasty.

Methods: Eighteen pairs of fresh osteoporotic femur specimens were collected and divided into two groups, A and B, 9 pairs in each group. Nine fresh osteoporotic femur specimens in each group were randomly selected for enhancement, and the corresponding contralateral specimens were used as control group.

rhPDGF-BB combined with ADSCs in the treatment of Achilles tendinitis via miR-363/PI3 K/Akt pathway.

To investigate the mechanism of recombinant human platelet-derived growth factor-BB (rhPDGF-BB) and human adipose-derived stem cells (hADSCs) in the treatment of Achilles tendinitis. Biomechanical indices of stiffness, stress, and maximum load-to-failure were detected by biomechanical test. mRNA and protein levels of miR-363, p-PI3K/AKT, tendon-related genes Collagen I, Scleraxis (Scx), and Tenascin C (TNC) were measured by qRT-PCR and western blot.

[Treatment of tibiofibular diastasis without ankle fracture with endobutton device].

Objective: To investigate the clinical effects of Endobutton device in the treatment of tibiofibular diastasis without ankle fracture.

Methods: From January 2009 to January 2011, a total of 8 patients with tibiofibular diastasis without ankle fracture were treated with Endobutton device. There were 6 males and 2 females with an average age of 34 years (ranged, 25 to 44 years).

[Treatment strategy of double disruption of the superior shoulder suspensor complex (SSSC)].

Objective: To discuss efficacy of the surgical treatment strategy of double disruption of the superior shoulder suspensor complex (SSSC).

Methods: The data of 15 patients with double disruption of the SSSC were retrospectively analyzed from January 2008 to December 2009. There were 11 males and 4 females, with an average age of 45.

Phase I clinical trial of nasopharyngeal radiotherapy and concurrent celecoxib for patients with locoregionally advanced nasopharyngeal carcinoma.

We evaluated the incidence of acute toxicity of concurrent cyclooxygenase-2 inhibitor (celecoxib) plus radiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC). Thirty-four patients received an accumulated radiation dose of 72-76Gy in 36-38 fractions to the primary lesion and 60Gy in 30 fractions to cervical lymph-node lesions. Palpable residual nodes were boosted to 70Gy at the 90% isodose level with an electron field.

[Application of elastic intramedullary nail in treating bilateral femoral shaft fractures in children].

Objective: To explore the curative effects and complications of elastic intramedullary nail in treating children's bilateral femoral shaft fractures.

Methods: Form February 2005 to March 2008, 7 patients with bilateral femoral shaft fractures were treated by closed reduction and internal fixation with elastic intramedullary nail. There were 5 males and 2 females.
