Hypertrophic pachymeningitis with co-occurrence of anti-neutrophil cytoplasmic antibodies and immunoglobulin G4 seropositivity: Case report and literature review.

We report an extremely rare case of hypertrophic pachymeningitis in which a 71-year-old man presented with an intractable recurrent headache for >1 year. During this period, he became positive for immunoglobulin G4 and proteinase 3-antineutrophil cytoplasmic antibodies. Contrast-enhanced magnetic resonance imaging showed characteristic diffuse thickening of the dura.

[Establishment of minireplicon system for severe fever with thrombocytopenia syndrome bunyavirus].

Severe fever with thrombocytopenia syndrome bunyavirus is a newly emerging virus in China, enveloped with a tripartite, single-stranded RNA genome of negative polarity. The regulatory elements for viral transcription and replication, as well as encapsidation and packaging signals, are thought to be located within these noncoding regions (NCRs). The terminal nucleotides are genus specific and highly conserved.
