Cestode larvae spend one phase of their two-phase life cycle in the viscera of rodents, but cases of cestodes infecting subterranean rodents have only been rarely observed. To experimentally gain some insight into this phenomenon, we captured approximately 300 plateau zokors(Eospalax baileyi), a typical subterranean rodent inhabiting the Qinghai-Tibet Plateau, and examined their livers for the presence of cysts. Totally, we collected five cysts, and using a mitochondrial gene(cox1) and two nuclear genes(pepck and pold) as genetic markers, we were able to analyze the taxonomy of the cysts. Both the maximum likelihood and Bayesian methods showed that the cysts share a monophyly with Taenia mustelae, while Kimura 2-parameter distances and number of different sites between our sequences and T. mustelae were far less than those found between the examined sequences and other Taeniidae species. These results, alongside supporting paraffin section histology, imply that the cysts found in plateau zokors can be regarded as larvae of T. mustelae, illustrating that zokors are a newly discovered intermediate host record of this parasite.

Excited states in the odd-proton nucleus 125Cs were investigated by means of in-beam β-ray spectroscopy. The πg7/2 band is observed to fork into a △I = 1 coupled band and a △I = 2 decoupled band at high spins. To assign the possible configurations of these two bands, experimental B（M1）/B（E2） ratios and signature splittings have been evaluated for the △I = 1 band, and calculations based on the geometrical model, cranked shell model and total Routhian surfaces model have been performed. They are suggested to be a near-oblate band built on the （πg7/2/d5/2）（vh11/2）2 configuration and a prolate band built on the πg7/2 （πh11/2）2 configuration, respectively.
