ABSTRACT
Albendazole (ABZ) is an antihelminthic drug used for the treatment of several parasitic infestations. In addition to this, there are reports on the anticancer activity of ABZ against a wide range of cancer types. However, its effect on glioma has not yet been reported. In the present study, cytotoxicity of ABZ and ABZ loaded solid lipid nanoparticles (ASLNs) was tested in human glioma/astrocytoma cell line (U-87 MG). Using glyceryl trimyristate as lipid carrier and tween 80 as surfactant spherical ASLNs with an average size of 218.4 ± 5.1 nm were prepared by a combination of high shear homogenization and probe sonication methods. A biphasic in vitro release pattern of ABZ from ASLNs was observed, where 82% of ABZ was released in 24 h. In vitro cell line studies have shown that ABZ in the form of ASLNs was more cytotoxic (IC50 = 4.90 µg/mL) to U-87 MG cells compared to ABZ in the free form (IC50 = 13.30 µg/mL) due to the efficient uptake of the former by these cells.

After more than3 years of pilot (since 2010), standardized training of resident physicians in Shanghai has made great progress, however, it still needs to be improved. Cerebral and spinal vascular diseases are main types of neurological diseases and they seriously influence people's life and health. Interventional neuroradiology plays an important role in the diagnosis and treatment of cerebral and spinal vascular diseases. However, in the current residency training system in Shanghai or other provinces of China, the training of interventional neuroradiology is not included. In this paper, the authors analyzed the important role of interventional neuroradiology in diagnosis and treatment of cerebral and spinal vascular disorders and discussed the feasibility, method, and time arrangement of including interventional neuroradiology curriculum into the schedule of neurology standardizedresidency training and hoped to provide reference for the relevant departments to formulate a future policy.
