DNA aneuploid analysis of patients of preoperative and postoperative treatment. The oral cells before and after treatment of YSGG-PDT were analyzed by TCT, and cytological classification and diagnosis were performed. DNA ploidy was used to analyze the changes in the number of DNA ploidy in oral cells before and after YSGG-PDT treatment. (a) The staining quality of cell smear preparation (Staining Feulgen, lens 100×); (b) The morphology of normal cells (Staining Feulgen, lens 100×); (c) The morphology of abnormal oral cells (Staining Feulgen, lens 400×); (d) Other abnormal cells, including pathogenic microorganisms (fungi, trichomonas, parasites, etc.) (Staining Feulgen, lens 400×); (e) The histogram shows the distribution of cells of different volumes and abnormal cell peaks (double peaks, three peaks, multiple peaks, abnormal peaks, etc.); (f) The scatter diagram shows the number of cells of different DNA ploidy.
