An Analysis on the Differential Expressing Characters of Metastasis-Relating Genes in the Nasopharyngeal Primary Cancerous Tissues of Untreated NPC Cases with Different Patterns / 中国中医药信息杂志

ABSTRACT

Objective To investigate the relationship between the differential expressing characters of metastasis-relating genes in the nasopharyngeal primary cancerous tissues of untreated nasopharyngeal carcinoma (NPC) cases and the patterns in the terms of Traditional Chinese Medicine (TCM) manifested by these patients. Methods Forty one untreated NPC cases included were differentiated for their own patterns respectively at first and biopsys were made to take tissue samples from the nasopharyngeal mass of them for histopathological diagnosis. Furthermore, expressing level determination of metastasis-relating genes nm23-H1 and VEGF165 was carried out among these samples to analyze the correlation of expressing activity of these genes with their firstly differentiated patterns respectively. Results The expressing level of nm23-H1 was significantly lower in the biopsied tissue samples of nasopharyngeal primary focus among the untreated NPC cases with a pattern of dual deficiency of Qi and Yin than those with the other two kinds of pattern, while the expressing level of VEGF165 was in a reverse way to that of nm23-H1 in its activity expression among these cases with the same kind of pattern (P
