Malignant glioma by surgery is difficult to completely remove, the recurrence rate is high, the survival period is short and the prognosis is poor, which poses a great threat to human health. This article mainly studies the related process that curcumin induces human glioma cell apoptosis by promoting reactive oxygen species production. In the experiment, glioma cells were processed and Uppsala 87 malignant glioma cells of human were cultured in vitro. 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide assay was used to detect the effect of curcumin on the proliferation of Uppsala 87 malignant glioma cells. The cells in each reagent group and control group treated with curcumin were treated with 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide colorimetric treatment at 24 h. Use flow cytometry to detect cell apoptosis. Cellular immunofluorescence was used to detect the effect of oxidase inhibitors on nuclear factor activation. Experimental data showed that the apoptotic rate of 0, 2.5, 5 mg/l, diallyl disulphide treatment groups were 12.3 %, 19.75 % and 26.44 %, respectively, indicating that diallyl disulphide caused an increase in the apoptotic rate of human promyelocytic leukemia cell line cells and the difference was statistically significant (p<0.05). The results show that curcumin can inhibit the proliferation of Uppsala 87 malignant glioma cells cultured in vitro, induce the differential expression of apoptosis-related genes and thus have a significant effect of promoting cell apoptosiss.
