[Intra-articular radioulnar ligament reconstruction for chronic instability of distal radioulnar joint].

Objective: To evaluate the effectiveness of intra-articular radioulnar ligament reconstruction in the treatment of chronic instability of the distal radioulnar joint.

Methods: Between January 2006 and June 2012, the intraarticular radioulnar ligament reconstruction was used to treat chronic instability of the distal radioulnar joint in 12 patients. Of 12 cases, 8 were males and 4 were females with an average age of 37.

Giant adenocarcinoma of unknown origin penetrating from the pelvic cavity to subcutaneous tissue: A case report and review of the literature.

In this study, we present a case of a 43-year-old female patient who was admitted to our hospital due to a giant mass on the left buttock. Imaging tests revealed that the mass was a solid-cystic tumor with a large size of 143×430×180 mm, penetrating from the pelvic cavity to the subcutaneous tissue. Pathology tests indicated a metastatic mucinous adenocarcinoma which was most likely of gastrointestinal origin.

[Retrospective study on staged treatment of long bone shaft fractures with severe thoracic trauma].

Objective: To evaluate the feasibility and efficacy of staged treatment of patients with long bone shaft fractures and severe thoracic trauma.

Methods: A retrospective study was performed on 41 patients with long bone shaft fractures and severe thoracic trauma who underwent staged treatment under the guidance of damage control orthopedics from January 2005 to October 2009 in our department. Among the patients,29 patients were male and 12 patients were female,with an average age of (37.

[Inhibitive effects of chitosan on proliferation of fibroblasts in vitro].

Objective: To investigate the effects of chitosan on the cell cycle of the human fibroblasts and on the Ki-67 antigen expression in vitro and to investigate the mechanism of chitosan preventing the postoperative tissue adhesion.

Methods: The cultured fibroblasts were treated for 48 hours with 0, 0.01, 0.

[Changes of neuropeptide Y mRNA expression in the cerebral tissues of rat models of subarachnoid hemorrhage].

Objective: To investigate the changes in the expression of neuropeptide Y mRNA in the cerebral tissues of rat models of subarachnoid hemorrhage (SAH), to shed light on the prevention and treatment of cerebral vasospasm induced by SAH.

Methods: SAH rat models, saline and sham-operation control groups were respectively established, in which the relative abundance of neuropeptide Y mRNA in the corpus striatum, cerebral cortex, hypothalamus were subsequently measured and compared by reverse transcriptase PCR at 15 min, 30 min and 1, 4, 8, 12, 24, 48 h after corresponding treatment.

Results: The abundance of neuropeptide Y mRNA significantly elevated in the cerebral tissues after SAH, and gradually declined with the passage of time, but were still significantly higher than that of saline and sham-operation controls at any of the same time points.
