We developed a special methylene blue solution for staining of cervix shedding cells based on catalytic oxidizing chromogenic reaction, which shows a potential for cervical cancer cytology screening. We screened a total of 1 922 women for cervical cancer with the special methylene blue staining method and a conventional Pap smear method using cervix shedding cells. Then, the patients with positive indicators of the Pap smear or this special solution staining method were examined by the electron colposcopy and histopathological examination. Staining of cervical exfoliated cells with this reactive oxygen-based special solution showed that the number of positive cases was 140 (7.28%). Among them, 21 cases showed dark green (1.09%), and 119 cases showed purple black (6.19%). The results of the Pap smear method showed that the num-ber of positive cases was 123 (6.40%), of which ASCUS was 105 (5.46%), ASC-H was 5 (0.26%), and LSIL was 9 (0.47%), and HSIL was 4 (0.21%). For cervical exfoliated cell special staining solution for screening cervical intraepithelial neoplasia (CIN-Ⅱ, CIN-Ⅲ) and cervical cancer, sensitivity was 83.33%, specificity was 65.52%, accuracy was 74.29%, missed diagnosis rate was 13.33%, positive coincidence rate was 51.43%, and the negative coincidence rate is 86.67%. Our results proved the value of this method for early screening of cervical cancer through clinical practice in China.
