Influence of preoperative simulation on the reduction quality and clinical outcomes of open reduction and internal fixation for complex proximal humerus fractures.

Purpose: Proximal humerus fractures (PHFs) are common. With the development of locking plates, open reduction and internal fixation (ORIF) of the proximal humerus can provide excellent clinical outcomes. The quality of fracture reduction is crucial in the locking plate fixation of proximal humeral fractures.

Circulating microRNA let‑7e is decreased in knee osteoarthritis, accompanied by elevated apoptosis and reduced autophagy.

Knee osteoarthritis (KOA) is a major cause of leg disability in the elderly population. Recently, the expression levels of circulating microRNA (miRNA) let‑7e have been reported to be significantly reduced in KOA. The aims of the present study were to assess the feasibility of let‑7e as a serum marker for detecting KOA and to explore the underlying mechanisms of its involvement.

Gastric foregut cystic developmental malformation: case series and literature review.

Foregut cystic developmental malformation (FCDM) is a very rare lesion of the alimentary tract, especially in the stomach. We discuss the concepts of gastric duplication cyst, bronchogenic cysts, and FCDM. Nomenclature has been inconsistent and confusing, but, by some definitions, gastric duplication cysts involve gastric mucosa and submucosal glands, bronchogenic cysts involve respiratory mucosa with underlying cartilage and glands, and FCDM lacks gastric mucosa or underlying glands or cartilage but has pseudostratified ciliated columnar epithelium (PCCE).

[Effective analysis of continous perfusion with Dandshen and heparin for treatment of femoral head necrosis].

Objective: To investigate the effect of continous perfusion with Danshen and heparin for treatment of femoral head necrosis.

Methods: From April 2004 to June 2007,42 patients of femoral head necrosis were treated by contious perfusing with Dandshen and heparin, included 24 males and 18 females with an average age of 39.2 years ranging from 13 to 61 years.

[Effect of static magnetic field on deep wound healing of SD rats].

Objective: To investigate the effect of static magnetic field on deep wound healing of SD rats and VEGF during the wound healing and different strength static magnetic field on deep wound healing of SD rats.

Methods: Divided forty-eight SD rats into three groups: 0.16 T magnetic disk treatment (0.

[Surgical treatment for the intradural extramedullary tumor in the spinal canal].

Objective: To study the clinical characteristics of the intradural extramedullary tumor in the spinal canal, as well as the application of internal fixation technique to restore the spinal stability in the surgical treatment of intradural extramedullary tumor in the spinal canal through posterior approach.

Methods: Among 24 patients receiving the tumor resection through posterior approach, 14 patients were male and 10 patients were female, ranging in age from 12 to 68 years, with an average of 40 years. Fourteen patients were treated with internal fixation and autogenous bone graft after tumor resection, and other 10 patients without internal fixation and autogenous bone graft.

[Treatment of fracture of the tubiform bone with domestic locking plate through minimal invasive incision and bridging reduction fixation].

Objective: To study the therapeutic method and clinical effect of domestic locking plate for treating fracture of the tubiform bone through a minimal incision and bridging fixation.

Methods: Among 40 patients with fracture of the tubiform bone, 29 patients were male and 11 patients were female, aged from 29 to 69 years, with the average of 38.27 years.
