METHODS: Kai-pu TM flow-through hybridization technique was used to detective the HPV type in 60 patients who was diagnosed as CIN with vaginoscope detective the HPV and TCT again in 3 months, 6 months and 12 months later. RESULTS: Before LEEP therapy the infection rates in CINⅠ, CINⅡ and CINⅢ were 23.10%, 85.70% and 96.20%.
