[Mixed craniopharyngioma: long-term results after gamma knife combined with stereotactic brachytherapy].

Objective: To evaluate the long-term results of combination treatment with Gamma Knife radiosurgery and stereotactic intracavitary brachytherapy for mixed cystic and solid craniopharyngiomas.

Methods: Sixty-seven consecutive patients with mixed cystic and solid craniopharyngioma treated by Gamma Knife radiosurgery combined with stereotactic brachytherapy from October 1996 to December 2005 were selected for retrospective analysis. The inclusion criterion was the patients who survived for at least 5 years after combined treatment.

[Controlled clinical trials of cost-effectiveness analysis on poking reduction and open reduction for the treatment of sanders type II calcaneal fractures].

Objective: To evaluate cost-effectiveness of poking reduction and open reduction for the treatment of Sanders type II calcaneal fractures, in order to provide evidence for standard treatment.

Methods: From 2006.10 to 2008.

[Clinical analysis of 1434 cases of frameless stereotactic operation].

Objective: Stereotactic operations were performed using a frameless stereotactic instrument manufactured by CAS-R-2 instead of traditional stereotactic frame. The aim of this study was to assess the clinical usefulness, accuracy and safety of frameless stereotactic instrument.

Methods: The clinical data of 1434 patients was retrospectively reviewed.

[Complications following gamma knife radiosurgery].

Objective: To investigate complication features following gamma knife radiosurgery (GKR), and to assess factors causing complications.

Methods: A retrospective analysis was conducted for 253 patients with intracranial arteriovenous malformation (AVMs), meningiomas, glial neoplasms, germinomas and metastatic cancer, respectively, which were treated with GKR.The incidences of acute, subacute and late complications following GKR were evaluated.
