The levels of women's awareness, experience, acceptability and preference for Vaginal Human Papillomavirus (HPV) self-sampling in three provinces of China: a cross-sectional study.

BACKGROUND: The primary screening technique for precancerous lesions and cervical cancer is human papillomavirus (HPV) testing, and HPV self-sampling has been shown to be consistent with clinician sampling in terms of the accuracy of the results and may improve cervical cancer screening rates. The aim of this study was to understand the level of awareness, experience, acceptability, and preference for vaginal HPV self-sampling among women in Jiangsu, Zhejiang, and Shanghai, China, and to analyze the possible influencing factors to determine the feasibility of implementing self-sampling. METHODS: Overall, 1793 women were included in the data analysis. A self-administered questionnaire was utilized. In addition to descriptive analysis, univariate and multivariate analyses were used to explore the associations between sociodemographic features, history of cervical cancer screening, and the level of awareness, experience, acceptability, and preference for HPV self-samples. RESULTS: The participants' level of awareness of and experience with HPV self-sampling were moderate. A total of 88.8% of participants rated the acceptability as "high", and self-sampling was preferred by 64.2% of them for cervical cancer screening. People aged 45 to 54 years showed a preference for both clinician sampling(OR = 1.762 (1.116-2.163)) and self-sampling (OR = 1.823 (1.233-2.697)). Those who had graduated from high school or above (OR = 2.305 (1.517-3.503), OR = 2.432 (1.570-3.768), OR = 3.258 (2.024-5.244)) preferred clinician-sampling, and those with a bachelor's degree or above (OR = 1.664 (1.042-2.657)) preferred self-sampling. Middle- and high-income individuals showed no preference for either sampling method (OR < 1). CONCLUSIONS: HPV self-sampling is widely accepted, but awareness, experience and preferences need to be improved. These results may help to adjust public health strategies for the early inclusion of HPV self-sampling as a screening method in national initiatives to prevent cervical cancer.

Experience and acceptability for HPV self-sampling among women in Jiangsu province, China: a cross-sectional survey.

This aim of this study was to investigate women's knowledge about HPV along with their experience and acceptability of self-sampling in Jiangsu province, China. A total of 862 women aged 25-63 years old from Jiangsu province who purchased an HPV self-sampling test kit were invited to complete a questionnaire designed by the authors. Participants had high acceptability for HPV self-sampling with a mean score of 4.2 (95% [CI], 4.1-4.22) out of 5 points. 27% of participants preferred clinician-sampling, 33% preferred self-sampling, other 40% expressed no preference. Women with good knowledge about HPV and with a good experience with HPV self-sampling were more acceptable for self-sampling (P < 0.05). The biggest concern about HPV self-sampling of the participants includes 'specimens' spoilage', 'incorrect sampling', 'can't get results in time', and so on. HPV self-sampling can be used to improve cervical cancer screening coverage and participation rates in China.

Cancer screening and can be an alternative primary screening for cervical cancer.•What the results of this study add? This study adds new findings about Chinese women's experience and acceptability of HPV self-sampling. We found that most women had high acceptability for HPV self-sampling in Jiangsu province, China, and high knowledge about HPV as well as good•What is already known on this subject? HPV self-sampling testing was proven to be useful for improving the uptake rate of cervical experience of self-sampling can improve the acceptability for self-sampling in women.•What the implications are of these findings for clinical practice and/or further research? Further research should assess the acceptability of women with less education or who never screened.

Systematic elucidation of the mechanism of geraniol via network pharmacology.

BACKGROUND: Geraniol is an acyclic monoterpene alcohol, which is extracted from the ethereal oils of aromatic plants. A systematic analysis of its mechanism of action has not yet been carried out. METHODS: In this study, the druggability of geraniol was assessed via Traditional Chinese Medicine Systems Pharmacology Database (TCMSP), and the potential targets of geraniol were identified using the Comparative Toxicogenomics Database (CTD). Additionally, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed using WebGestalt. Drug-target-pathway networks were constructed using Cytoscape to give a visual view. RESULTS: Our findings showed that geraniol has superb druggability with 38 putative identified target genes. GO, KEGG, and network analyses revealed that these targets were associated with cancer, inflammatory immunoreactions, and other physiological processes. CONCLUSION: Geraniol is predicted to target multiple proteins and pathways that shape a network which can exert systematic pharmacological effects.

Geraniol suppresses proinflammatory mediators in phorbol 12-myristate 13-acetate with A23187-induced HMC-1 cells.

BACKGROUND: Geraniol is a monoterpene alcohol that has anti-fungal, anti-cancer and anti-nociceptive properties, but its anti-allergic rhinitis (AR) property is unclear. METHODS: In this study, the anti-inflammatory role and its possible mechanisms of geraniol in human mast cell line (HMC-1) cells stimulated by inflammatory trigger phorbol 12-myristate 13-acetate plus A23187 (PMACI), as well as in ovalbumin (OVA)-induced AR mice models were investigated. RESULTS: PMACI results in a significant increase in the production of proinflammatory cytokines, such as TNF-α, IL-1ß, MCP-1, IL-6 and as well as histamine. Geraniol was found to inhibit both TNF-α, IL-1ß and IL-6 protein and mRNA expressions at concentrations of 40, 80, 160 µM. In OVA-induced AR models, geraniol treatment was able to suppress AR biomarkers (OVA-specific IgE and IL-1ß as well as histamine) and nasal rub scores. Interestingly, p38, a member of the mitogen-activated protein kinase (MAPK) signaling family, was found to be increasingly hypophosphorylated as geraniol dose was increased. Similar decreases in the nuclear level of p65, a member of the nuclear factor kappa B (NF-κB) signaling pathway, were also observed. CONCLUSION: Our data highlights that the anti-inflammatory properties of geraniol on AR-related markers in activated HCM-1 cells and OVA-induced AR models may be mediated through the regulation of the MAPK/NF-κB signaling pathway.
