Non-Hodgkin lymphoma (NHL) is a common lymphoid hematological malignancy, the treatment and prognosis of NHL have always been the focus of clinical attention. Chemotherapy is the main first-line treatment, but there is still no effective treatment for patients with poor response to chemotherapy, recurrence or progression within a short period of time after treatment, and new and effective drugs need to be developed clinically. As the only clinically validated oral selective inhibitor of nuclear export (SINE), Selinexor has been approved for the treatment of relapsed/refractory diffuse large B-cell lymphoma and multiple myeloma, clinical attempts are being made to apply it to the treatment of other hematological malignancies.This article reviews the anti-tumor mechanism of Selinexor and the latest research progress in its application in NHL, and provides ideas for a more diverse, standardized and effective applications of Selinexor in NHL.

AIMTo evaluate the antioxidant capacity and quality of traditional Chinese medicines using TLC-bioautography.

METHODSTwo chromatograms of each crude drug sample were obtained, after developing, by spraying with 1,1-diphenyl-2-picrylhydrazyl (DPPH) solution in ethanol and classical stained reagents, separately. The images sprayed with DPPH solution were captured under light after the plates were heated at 40 degrees C for 30 min, and scanned using video scan software to get peak areas of active compounds.

RESULTSTotal peak areas of the spots on TLC were calculated to evaluate the antioxidant capacity of the tested crude drugs from different habitats and sources. The results indicated that Radix Linderae cultivated in Tiantai (Zhejiang province), Cortex Magnoliae Officinalis cultivated in Liangshan (Sichuan province), and Fructus Perillae acquired in Shanghai have the highest scavenging properties towards DPPH in their respective TLC-autographic assays. Norisoboldine, magnolol and honokiol, luteolin, apigenin and an unknown compound "U" proved to be the major antioxidant components in the corresponding crude drugs as they contribute the dominating peak areas to the total ones.

CONCLUSIONTLC-bioautography can not only be used for screening of the components with antioxidant potency but also for the purpose of quality evaluation of traditional Chinese medicines at the same time, and the method proved to be selective, simple and reproducible.

OBJECTIVETo elvaulate the antioxidant activity of the pigment of Lycium ruthenicum.

METHODThe antioxidant activities were measured by the effects of the reducing ability, scavenging DPPH. H2O2-induced hemolysis of mice erythrocyte, serum resistance of reactive oxygen species, content of MDA in liver tissue, and swelling effect of mitochondria in liver tissue.

RESULTThe pigment of L. ruthenicum could scaveng DPPH* remarkably with IC50 0.164 mg x mL(-1), inhibitte hemolysis of mice erythrocyte evidently with IC50 0.112 mg x mL(-1). The resistant of reactive oxygen species was enhanced by the tested substances, simultanously. The concentration of MDA of peroxidation of lipid in mice liver could be reduced, and the swelling of mice liver mitochondria alse be restrained.

CONCLUSIONThe pigment of L. ruthenicum has antioxidant activity in tested concentration.
