Objective: The aim of the present study is to explore the mechanism of action of several proteins, including Epstein-Barr virus (EBV), B-cell lymphoma (Bcl)-2, p53, c-Myc and retinoblastoma (Rb), in Non-Hodgkin's lymphoma (NHL).
Patients And Methods: Between July 2010 and July 2015, samples of 142 patients with pathologically confirmed NHL which presented at our institution were included in the observation group. In addition, samples from 55 patients with hyperplastic lymphadenitis presented during the same period were enrolled as control group. The expressions of EBV (+), p53(+), Bcl-2(+), Rb(-) and c-Myc(+) were determined and compared
Patients And Methods: Between July 2010 and July 2015, samples of 142 patients with pathologically confirmed NHL which presented at our institution were included in the observation group. In addition, samples from 55 patients with hyperplastic lymphadenitis presented during the same period were enrolled as control group. The expressions of EBV (+), p53(+), Bcl-2(+), Rb(-) and c-Myc(+) were determined and compared among different subtypes and stages of NHLs of observation group. Besides, the correlation of EBV with p53, Bcl-2, Rb and c-Myc were investigated in NHLs of observation group.
Results: In the observation group, the expression rates of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) were significantly higher than those, respectively, in the control group (p < 0.05). No significant correlation was observed between EBV expression and the expressions of p53, Bcl-2, Rb and c-Myc in the observation group (p > 0.05). The expression rates of p53(+) and Bcl-2(+) were significantly higher in aggressive and highly-aggressive NHLs than in indolent NHLs of the observation group (p < 0.05). The expressions of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) were significantly higher in stage III-IV NHLs than in stage I-II NHLs (p < 0.05).
Conclusions: The expressions of EBV(+), p53(+), Bcl-2(+), Rb(-), and c-Myc(+) are closely associated with NHL pathogenesis. Expressions of these proteins are higher in later stages of NHLs, and expressions of p53(+) and Bcl-2(+) are higher in more aggressive NHLs.

Donafenib is an improved version of sorafenib in which deuterium is substituted into the drug's chemical structure, enhancing its stability and antitumor activity. Donafenib exhibits enhanced antitumor activity and better tolerance than sorafenib in preclinical and clinical studies. However, the specific mechanism of its effect on hepatocellular carcinoma has not been reported.

The present study aims to explore the anticancer efficacy of Diosmin by inducing mitochondrial-mediated apoptosis in human epidermoid carcinoma cells (Hep-2). This is done by cell line assays and studying crucial inflammatory and apoptotic signaling molecules. The cytotoxicity property of Diosmin was evaluated by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay.

Objective: To investigate the clinical features, gene mutation profile, efficacy and prognostic factors of primary extranodal diffuse large B-cell lymphoma(EN-DLBCL).
Methods: A retrospective analysis was performed for 382 patients with primary EN-DLBCL with complete clinical data who were treated in West China Hospital from January 2013 to January 2023, and their clinical characteristics,gene mutation profile, efficacy and prognostic factors were analyzed.
Results: The median age of the 382 patients with EN-DLBCL was 56(18-89) years old.
