[Correlation between Serum miR-34a Level and Thrombocytopenia after Chemotherapy in Patients with Diffuse Large B-Cell Lymphoma].

Objective: To analyze the relationship between serum miR-34a level and thrombocytopenia after chemotherapy in patients with diffuse large B-cell lymphoma (DLBCL).

Methods: A total of 69 eligible DLBCL patients who received chemotherapy in our hospital from January 2018 to January 2020 were prospectively included as the research subjects, all patients received R-CHOP 21 regimen (rituximab + cyclophosphamide + adriamycin + vincristine + prednisone) for chemotherapy, 3 weeks was 1 cycle, and 2 cycles of chemotherapy were used. The patients were divided into a reduction group and a non reduction group according to whether there was thrombocytopenia after chemotherapy, the general data and laboratory indexes of the two groups were investigated and compared, the relationship between serum miR-34a before chemotherapy and thrombocytopenia after chemotherapy in patients was analyzed.

[Effect of MiR-142-3p Targeting HOXA5 on Proliferation, Cycle Arrest and Apoptosis of Acute B Lymphocytic Leukemia Cells].

Objective: To investigate the effect and molecular mechanism of miR-142-3p to the proliferation, cycle and apoptosis of acute B lymphocytic leukemia (B-ALL) cells by regulating the homeobox gene 5 (HOXA5) expression.

Methods: Real-time fluorescence quantitative PCR was used to detect the expression levels of miR-142-3p and HOXA5 in human B-ALL cell Nalm6 cell line and human B lymphoblast Hmy2-cir cells. Nalm6 was transfected by using liposome transfection technology, miR-142-3p mimic, pcDNA-HOXA5 overexpression plasmid, miR-142-3p mimic+pcDNA-HOXA5 overexpression plasmid, and control.

Polymorphic variation of inflammation-related genes and risk of non-Hodgkin lymphoma for Uygur and Han Chinese in Xinjiang.

Polymorphisms of inflammation-related genes have been found to be associated with non-Hodgkin lymphoma (NHL) or some of its subtypes, but only a few relevant data have been reported in China. In this study, the Snapshot method was used to assess genetic variation; a total of 14 single nucleotide polymorphisms (SNPs) for 6 inflammatory factors in 157 NHL cases (64 Uygur ethnic subjects, 93 Han Chinese) and 435 controls (231 Uygur and 204 Han Chinese) were studied from the Xinjiang province of China. Haplotype distribution was estimated using PHASE 2.
