Relationship Between Syndrome Patterns of Traditional Chinese Medicine and Apoptosis- Related Oncogene mRNA Expressions in Precancerous Lesions of Gastric Cancer / 广州中医药大学学报

ABSTRACT

[Objective] To study the relationship between syndrome patterns of traditional Chinese medicine and bcl- 2 oncogene, p53 suppression gene mRNA expressions in precancerous lesions of gastric cancer (PIGC). [Methods] Forty PLGC cases were endoscopically and pathologically confinned, including 24 cases of moderate dysplasia of gastric mucosa, 9 cases of severe dysplasia, 7 cases of incomplete colonic intestinal metaplasia. Of the 40 cases, 10 were complicated with Qi stagnation, 12 with stomach-heat, and 18 with blood stasis, mRNA expression of bcl- 2 oncogene and p53 suppression gene were detected in situ by molecular hybridization method. [Results] The mRNA overexpression of bcl- 2 oncogene and p53 suppression gene were found in PLGC, and the expression was gradually increased with the progress of lesions. In the complicated cases, the mRNA expression of bcl- 2 oncogene and p53 suppression gene were the least in the cases with Qi stagnation and less in the cases with stomach- heat than in the cases with blood stasis. [Conclusion] Abnormal mRNA expression of bcl- 2 oncogene and p53 suppression gene were found in PLGC cases and related with different complicated cases, indicating the specificity of different syndrome patterns.
