Background and objective China carries a heavy burden of cervical cancer and has an alarmingly low cervical cancer screening rate. In order to achieve the goal of cervical cancer elimination, there is an urgent need for suitable methods and strategies in China. Materials and methods A total 9972 woman who received cervical cancer screening services of National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in 8 project counties participated in this study. TruScreen, HPV test and LBC test were performed in all participants. A total of 1945women had one or more than one positive or abnormal screening results of the above three screening tests subsequently received colposcopy. The detection rate of CIN2+ between the three tests were compared. Results No matter what kind of screening method is used, the CIN2+ detection rate in the eastern regions was much higher than that in the central and western regions. The total detection rate of CIN2+ in HPV group was highest (0.73%), following in LBC group (0.44%) and TS group (0.31%). There was statistically significant difference in the total detection rate of CIN2+ between TS and HPV groups, LBC and HPV groups, respectively. There was no statistical difference in the total detection rate of CIN2+ between TS and LBC screening groups. Moreover, except for the eastern regions, there was no statistical difference in the detection rate of CIN2+ between TS group and the other two groups in central and western regions. Conclusion If it can meet the requirements of the laboratory and personnel, HPV test seems to be the preferred method for cervical cancer screening in rural areas of China. The characteristics of minimal training requirements, simple operation, real-time results obtained without the collection of cervical cell samples and the help of laboratory equipment and cytologists of TS make it ideal for cervical cancer screening in low-resource regions.

Objective. We investigated the characteristics of vaginal microbiome in reproductive-age females with HPV infection in Xinjiang, China. Methods. A total of 135 females of reproductive age were enrolled. There were 43 healthy HPV-negative females in control group (N group), 58 HPV-positive females in nonlesion group (P1 group), and 34 HPV-positive females in low-grade squamous intraepithelial lesion group (P2 group). DNA was extracted from the vaginal secretions, and V3–V4 regions of bacterial 16S rDNA were amplified and sequenced by NovaSeq. QIIME2 and R software were used to perform diversity analysis of bacteria. PICRUSt2 was used to predict the function of the vaginal microbiota. Results. Lactobacillus was the main genus of vaginal microbiota in asymptomatic reproductive-age females with or without HPV in Xinjiang. The diversity of vaginal microbiota in the P1 group was significantly higher than that in the N group, and the proportion of Gardnerella increased significantly. The vaginal microbiota structure of the P2 group was different from the N group, characterized by the decrease of Lactobacillus crispatus and the increase of Shuttleworthia. The function of the inordinate microbiome may play a role in accelerating HPV replication and integration. Conclusion. The structure of vaginal microbiota alters under persistent HPV infection in asymptomatic females of reproductive age in Xinjiang. The Gardnerella increase is associated with increased susceptibility to HPV infection, and Lactobacillus iners predominance and Shuttleworthia presence may be a signature of HPV infection with low-grade squamous intraepithelial lesion.
