[Correlation between Serum Interleukin-33, β-Microglobulin Levels and DS Stage in Patients with Multiple Myeloma].

Objective: To investigate the correlation between serum interleukin-33 (IL-33), βmicroglobulin (β-MG) levels and Durie-Salmon (DS) stage in patients with multiple myeloma (MM).

Methods: 100 MM patients admitted to the First Affiliated Hospital of Fujian Medical University from March 2019 to January 2021 were selected and divided into stage I, stage II and stage III groups according to the DS staging system. A baseline data questionnaire of patients was designed, then the relevant baseline data and laboratory test results of patients were recorded.

[Advances in the studies of spermatogonial stem cells in primate mammals].

Spermatogonial stem cells(SSCs) are a type of spermatogonial cells that play an important role in the spermatogenesis of males. SSCs not only possess the properties of stem cells but also differentiate into sperm. They are the unique adult stem cells that transmit genetic information to subsequent generations.
