[Follicular Helper T Cells and Expression of PD-1 in Mice with Myelodysplastic Syndrome].

Objective: To investigate the complete blood count, morphological changes, follicular T helper (Tfh) cells and expression of PD-1 in bone marrow and spleen of mice with myelodysplastic syndrome(MDS) and to explore their significance in pathogenesis of MDS.

Methods: The 10 male NUP98-HOXD13 transgenic mice and 10 male homologous wild-type C57BL/6J mice were used for experments. The complete blood count, morphological change of NUP98-HOXD13 transgenic mice and wild-type C57BL/6J were detected by routine methods.

The effect of GJB2 and SLC26A4 gene mutations on rehabilitative outcomes in pediatric cochlear implant patients.

To analyze the treatment outcomes in pediatric cochlear implant patients with mutations in GJB2 or SLC26A4 and to determine these mutations' impact on rehabilitative outcomes. The study included 41 children who received unilateral cochlear implantations. Fifteen of these children had GJB2-related deafness, 10 had SLC26A4-related deafness, and 16 had deafness of unknown etiology.
