Comparison between ixazomib+cyclophosphamide+dexamethasone regimen and ixazomib+dexamethasone regimen for elderly and frail patients having newly diagnosed multiple myeloma.

Aims: The purpose of this prospective, randomized study was to investigate the effectiveness and safety of the ixazomib+cyclophosphamide+dexamethasone (ICd) and ixazomib+dexamethasone (Id) regimens in newly diagnosed multiple myeloma (NDMM) who were elderly and frail and to compare the two regimens.

Methods: Patients were randomly grouped into ICd and Id group. The primary end point was ORR, and patients who received at least two cycles were analyzed.

Association between interleukin gene polymorphisms and multiple myeloma susceptibility.

The present study performed a retrospective observational study in order to investigate the relationship between the interleukin family gene polymorphisms and risk of multiple myeloma (MM), based on sixteen case-control studies that contained 2,597 patients with MM and 3,851 controls. The results demonstrated that the genotypes IL-6 and IL-1 GG increased the risk of MM by approximately 40.8 and 80.

[Effect of Shh and BM-MSC Synergism on the Proliferation of Hematopoietic Stem Cells].

Objective: To study the effect and mechanism of shh and mesenchymal stem cell（MSC）synergism on the proliferation of hematopoietic stem cells in noninvasive co-culture system in vitro.

Methods: The mesenchymal stem cells were cultured in vitro，CD34 cells were sorted by mini MACS magnetic bead separator，flow cytometry was used to identify the purity of 2 cells. CD34 cells and MSCs were seeded to upper and low of transwell respecibely for non-contact coculture，and add exogenous shh protein for intervenece.

[Influencing Factors of Nosocomial Infection after Chemotherapy in Adult Patients with Acute Myeloid Leukemia and Its Control Strategy].

Objective: To investigate the influencing factors of nosocomial infection in adult patients with acute myeloid leukemia (AML) and its control strategies.

Methods: The clinical data of 109 patients with AML treated in our hospital from June 2014 to June 2017 were retrospectively analyzed. The clinical factors were analyzed retrospectively, and the influencing factors of infection after chemotherapy were explored.
