In China, the incidence rate and mortality rate of gastric cancer are in the second place among all tumors and the pathological type is mainly adenocarcinoma. The higher prevalence rate requires us to do more research. It is of great significance to study the antitumor effect of hydroxysafflor yellow pigment A in gastric adenocarcinoma. The aim of this study was to investigate the inhibitory effect of hydroxysafflor yellow pigment A on human gastric adenocarcinoma BGC-823 xenograft in nude mice. The animal model of human gastric adenocarcinoma BGC-823 was established in nude mice to carry out the experiment and then the transmission electron microscope was used to observe and analyze the experimental data. The results showed that on the 4th d after inoculation, there were more subcutaneous tumor masses in nude mice and on the 7th d, all the nude mice formed tumor blocks with the size of 0.4 cm to 0.8 cm and the tumorigenesis rate was 100 %. With the continuous administration, the tumor weight of the small dose group was only 0.88 g, which was much smaller than that of the model group. The average percentage of early apoptosis in low dose group was 2.48 % and that in model group was 0.44 %. In the low dose group, the volume of tumor cells became smaller and apoptotic bodies appeared. Therefore, it is of great significance to study the inhibitory effect of hydroxysafflor yellow pigment A on human gastric adenocarcinoma BGC- 823 xenograft in nude mice.
