[Antineutrophil cytoplasmic antibody associated vasculitis induced by antithyroid agents].
To investigate the significance of antineutrophil cytoplasmic antibody (ANCA) in hyperthyroidism at different stages and treated with different drugs and to investigate the relationship between the ANCA specific target antigens and the clinical manifestations of vasculitis. ⋯ PTU is associated with the production of ANCA in patients with hyperthyroidism. PTU induced ANCA is caused by polyclonal activation of B cells. Anti-MPO antibody may be related to the occurrence of clinical vasculitis.

[Application of diffusion-weighted and perfusion magnetic resonance imaging in definition of the ischemic penumbra in hyperacute cerebral infarction].
To investigate the value of diffusion-weighted imaging (DWI) and perfusion imaging (PI) in definition of the ischemic penumbra in hyperacute cerebral infarction. ⋯ Combination of DWI and PI clearly defines the ischemic penumbra in hyperacute stroke patient, thus laying, thus laying a basis for therapeutic intervention plan for stroke patients.
