The experimental results show that: DNA of normal gastric mucosa has stable phosphate backbone; Since the peak intensity at 1090 cm^(-1) is lower than that at 1050 cm^(-1), phosphate backbone in DNA of intestinal metaplasia becomes unstable, while the rest spectra peaks are similar to those in normal gastric mucosa; In terms of adenocarcinoma DNA, double peaks at 1090 cm^(-1) whose intensity are higher than 1050 cm^(-1), are observed, which indicates that DNA chain is broken and re-forms a double stabilized phosphate backbones. In addition, peaks at 950 cm^(-1), 1010 cm^(-1), 1100~1600 cm^(-1) also exhibit obvious difference compared with normal gastric mucosa, which shows that deoxyribose and bases are changed due to broken of DNA.
