Non-small cell lung cancer(NSCLC)is one of the malignant tumors with high morbidity and mortality worldwide.Ferroptosis is a new type of programmed cell death caused by abnormal accumulation of iron-dependent reactive oxygen species(ROS)leading to lipid peroxidation.It involves the balance between iron metabolism,lipid metabolism,oxy-gen free radical reaction and lipid peroxidation.Recent studies have found that ferroptosis is closely related to the occurrence and development of NSCLC.Due to the emergence of chemotherapy resistance and radiotherapy resistance in the treatment of NSCLC,there is an urgent need to develop new effective drugs and treatment strategies.Traditional Chinese medicine has unique advantages in the prevention and treatment of NSCLC due to its multi-targets and minimal side effects.In this review,we summarize the mechanism of ferroptosis in NSCLC,and discuss the research status of active ingredients of traditional Chinese medicine,single-herb traditional Chinese medicine and Chinese herbal compounds in the intervention of NSCLC through ferroptosis,in order to provide a new theoretical basis for the research of ferroptosis pathway and the prevention and treatment of NSCLC by targeted ferroptosis of traditional Chinese medicine.

Curriculum ideological and political is an important measure to realize fundamental task of"cultivating people by virtue".In recent years,our course team has carried out ideological and political education exploration and practice of course of Micro-biology and Immunology based on blended online and offline teaching model.From course objectives,teachers'teaching ability,all aspects of online and offline teaching,ideological and political education is organically integrated into whole process,aiming to culti-vate medical talents with"both ability and morality".

This paper compared the differences between two kinds of Bufonis Venenum produced by Bufo gargarizans gargarizans and B. gararizans andrewsi, and verified the rationality of the market value orientation of Bufonis Venenum based on the zebrafish mo-del. Twenty batches of Bufonis Venenum from Jiangsu province, Hebei province, Liaoning province, Jilin province, and Liangshan, Sichuan province, including B. gargarizans gargarizans and B. gararizans andrewsi, were collected. The UHPLC-LTQ-Orbitrap-MS combined with principal component analysis was used to compare the differences between two kinds of Bufonis Venenum. According to the limiting conditions of VIP>1, FC<0.5 or FC>2.0, and peak total area ratio>1%, 9 differential markers were determined, which were cinobufagin, cinobufotalin, arenobufagin, resibufogenin, scillaredin A, resibufagin, 3-(N-suberoylargininyl)-arenobufagin, 3-(N-suberoylargininyl)-marinobufagin, and 3-(N-suberoylargininyl)-resibufogenin. The content of 20 batches of Bufonis Venenum was determined according to the Chinese Pharmacopoeia(2020 edition) by high-performance liquid chromatography, and the 2 batches of Bufonis Venenum, CS7(8.99% of total content) and CS9(5.03% of total content), with the largest difference in the total content of the three quality control indexes of the Chinese Pharmacopoeia(bufalin, cinobufagin, and resibufogenin) were selected to evaluate their anti-liver tumor activity based on the zebrafish model. The tumor inhibition rates of the 2 batches were 38.06% and 45.29%, respectively, proving that only using the quality control indexes of the Chinese Pharmacopoeia as the value orientation of Bufonis Venenum market circulation was unreasonable. This research provides data support for the effective utilization of Bufonis Venenum resources and the establishment of a rational quality evaluation system of Bufonis Venenum.
