Positron emission tomography （PET）/computed tomography （CT） demonstrated a primary tumor on the pancreatic tail with multifocal liver metastases. Pathological and immunohistochemistry staining revealed the lesion to be a pancreatic neuroendocrine tumor （pNET）. According to the latest World Health Organization （WHO, 2013） classification, the tumor was classified as stage IV fimctional G1 pNET. After referral to the multidisciplinary treatment board （MDT）, the patient was started on periodic dose of omeprazole, somatostatin analogues and Interferon α （IFNα） and had scanning follow-ups. Based upon the imaging results, CT-guided radioactive iodine-125 （1251） seeds implantation therapy, radiofrequency ablation therapy （RFA） or microwave ablation technique were chosen for the treatment of the primary tumor. Transarterial chemoembolization （TACE）, RFA and microwave ablation techniques were decided upon for liver metastases. The patient showed beneficial response to the treatment with clinically manageable low-grade side effects and attained partial remission （RECIST criteria） with a good quality of life.展开更多

It is the causative agent of Japanese encephalitis with approximately 50,000 infection cases and 10,000 fatal cases annually in Asia （Erlanger et al., 2009）. Although liveattenuated JEV vaccine has been developed and used for human and pig vaccination, JE occurs epidemically or sporadically in some developing countries or even in vaccinated areas （Solomon, 2006）. Host resistance factors play an important role in the outcome of viral infection.展开更多

Preoperative functional MRI was performed to locate Broca＇s or Wernicke＇s area, and the cortex that was essential for language function was determined by electrocortical mapping. A site-by-site comparison between functional MRI and electrocortical mapping was performed with the aid of a neuronavigation device. Results showed that the sensitivity and specificity of preoperative functional MRI were 80.0% and 85.0% in Broca＇s area and 66.6% and 85.2% in Wemicke＇s area, respectively. These experimental findings indicate that functional MRI is an accurate, reliable technique with which to identify the location of Wernicke＇s area or Broca＇s area in patients with brain tumors.展开更多
