Anatomy and clinical application of suprascapular nerve to accessory nerve transfer.

Background: Loss of motor function in the trapezius muscle is one complication of radical neck dissection after cutting the accessory nerve (AN) during surgery. Nerve repair is an effective method to restore trapezius muscle function, and includes neurolysis, direct suture, and nerve grafting. The suprascapular nerve (SCN) and AN are next to each other in position.

Evolution of transmaxillary approach to tumors in pterygopalatine fossa and infratemporal fossa: anatomic simulation and clinical practice.

Background: The endoscopic transnasal approach has been proven to have advantages on the removal of the tumors in pterygopalatine fossa (PPF) and infratemporal fossa (ITF). Herein, this study aimed to describe a modified approach for resection of the tumors in these areas, both in cadaveric specimen and clinical patients.

Methods: The 20 adult cadaveric specimens and five patients with tumors in PPF and ITF were enrolled in this study.

I interstitial brachytherapy in management of pediatric skull base tumors.

Background: The purpose of this study was to present our preliminary assessment of the safety and efficacy of I interstitial brachytherapy (IBT) in the management of pediatric skull base tumors.

Methods: Thirty pediatric patients with skull base tumors treated with I IBT from April 2007 to May 2017 were included in this study. The probabilities of local control (LC) and overall survival (OS) were calculated by the Kaplan-Meier method.

[Application of superficial temporal artery to middle cerebral artery bypass in treatment of cerebral artery steno-occlusive disease].

Objective: To explore the effect of superficial temporal artery to middle cerebral artery(STA-MCA) bypass in treatment of cerebrovascular disease.

Methods: Fifty-two patients with atherosclerotic carotid artery occlusion or middle cerebral artery occlusion or moyamoya disease were included in this study. There were both clinical ischemic manifestation and hemodynamic dysfunction detected by perfusion CT in all the patients.

Virtual reality system for diagnosis and therapeutic planning of cerebral aneurysms.

Background: The virtual reality (VR) system can provide the neurosurgeon to intuitively interact with and manipulate the three dimensional (3-D) image similarly to manipulate a real object. It was seldom reported that the system was used in diagnosis and treatment of cerebral aneurysms. This study aimed to investigate the application of VR system in diagnosis and therapeutic planning of cerebral aneurysms.

[HIV-1 molecular epidemiological survey of drug users in Jiangxi province].

Objective: To investigate HIV-1 molecular epidemiology of drug users in Jiangxi Province to analyze epidemic situation, subtype, origin of strain, and variation, and to provide information for prevention and control of AIDS.

Methods: Combining principles of traditional epidemiology and molecular epidemiology, the authors analyzed the epidemiologically related factors, the gene sequences and systematic mutation of HIV-1 gene in nine drug users in Jiangxi province.

Results: The HIV spread through the drug users in Jiangxi not only by injection but also by sexual contacts.
