研究目的:

本课题拟在提出“湿热蕴结证大肠癌存在特异基因的甲基化,‘湿热’之邪可能激活相关信号通路,促进其癌变进程”的假说和已发现大肠癌的癌前病变相关蛋白如CDX2、hMLH1、p16在湿热证及虚证大肠腺瘤中多有差异表达的前期工作基础上,检测早期结直肠癌关键基因SPG20,SFRP2甲基化水平,探究外周血ctDNA 与中医湿热蕴结证的关联,以期通过检测血液ctDNA联合中医辨证提高肠癌早期筛查率,为结直肠癌二级预防提供新思路。

Objectives of Study:

Based on the hypothesis that there is methylation of specific genes in colorectal cancer in damp-heat syndrome, the pathogenic factor of damp-heat may activate relevant signaling pathways and promote the carcinogenesis process, and previous work that has found that precancerous proteins related to colorectal cancer, such as CDX2, hMLH1 and p16, are differentlyexpressed in colorectal adenomas in damp-heat syndrome and deficiency syndrome, The methylation levels of key genes SPG20 and SFRP2 in early colorectal cancer were detected, and the correlation between peripheral blood ctDNA and TCM damp-heat accumulation syndrome was explored, with a view to improving the early screening rate of colorectal cancer by detecting blood ctDNA combined with TCM syndrome differentiation, and providing new ideas for secondary prevention of colorectal cancer.
