To study a case of a middle-aged male with a non-tumor-associated Epstein–Barr virus (EBV) infection associated with Anti-N-methyl-D-aspartate receptor encephalitis (NMDARE), to explore the role of EBV in the pathogenesis of anti-NMDARE. The patient was diagnosed with "Anti-NMDARE, EBV infection" by using Cerebrospinal fluid (CSF) autoimmune encephalitis profile, and Metagenomics Next-Generation Sequencing (mNGS) pathogenic microbial assays, we discuss the relationship between EBV and NMDARE by reviewed literature. EBV infection may trigger and enhance anti-NMDARE, and the higher the titer of NMDAR antibody, the more severe the clinical presentation. [ABSTRACT FROM AUTHOR]

The N,N′-bis(ferrocenylmethylene)-1,2-phenylenediamine Schiff base (BFPDA) was synthesized by the condensation of ferrocenylaldehyde with 1,2-phenylenediamine. The complexes of BFPDA with Gd(III), Pr(III), Nd(III), Yb(III), Eu(III) and Er(III) were synthesized by template synthesis. The composition and properties of BFPDA and six rare earth metal complexes were determined by elemental analyses, IR, 1H NMR, UV-Vis spectra and molar conductance. [ABSTRACT FROM AUTHOR]
