Abstract
OBJECTIVE Some studies have reported that the prognosis of total laparoscopic hysterectomy (TLH) for early-stage cervical cancer (CC) is worse than that of open surgery. And this was associated with the use of uterine manipulator or not. Therefore, this study retrospectively analyzes the efficacy and safety of TLH without uterine manipulator combined with pelvic lymphadenectomy for early-stage CC. METHODS Fifty-eight patients with CC (stage IB1-IIA1) who received radical hysterectomy from September 2019 to January 2020 were divided into no uterine manipulator (n = 26) and uterine manipulator group (n = 32). Then, clinical characteristics were collected and intraoperative/postoperative related indicators were compared. RESULTS Patients in the no uterine manipulator group had significantly higher operation time and blood loss than in the uterine manipulator group. Notably, there was no significant difference in hemoglobin change, blood transfusion rate, number of pelvic nodules, anal exhaust time, complications and recurrence rate between the two groups. Additionally, patients in the uterine manipulator group were prone to urinary retention (15.6%) and lymphocyst (12.5%), while the no uterine manipulator group exhibited high probability of bladder dysfunction (23.1%) and urinary retention (15.4%). Furthermore, the 1-year disease-free survival rate and the 1-year overall survival rate were not significantly different between the two groups. CONCLUSION There was no significant difference in the efficacy and safety of TLH with or without uterine manipulator combined with pelvic lymphadenectomy in the treatment of patients with early-stage CC. However, the latter requires consideration of the negative effects of high operation time and blood loss.

Abstract
Background China has low human papillomavirus(HPV) vaccination rate due to lack of public funding and mistrust in domestic vaccines. This pilot study evaluated the feasibility and preliminary effectiveness of an innovative pay-it-forward strategy, which has a participant receive a subsidized vaccine and offers her an opportunity to donate to support other girls, in improving HPV vaccine uptake among 15-18-year-old adolescent girls. Methods A two-arm randomized controlled pilot trial was performed in one vaccination clinic in Western China. Adolescent girls (via caregivers) were invited to participate the study via online dissemination of the pilot study. Eligible ones were then randomly allocated using a sealed envelope method into standard-of-care or pay-it-forward arm in a 1:1 ratio. Pay-it-forward participants received hand-written postcard messages, a subsidized vaccine, and an opportunity to donate and (or) write postcards for future recipient girls. Standard-of-care participants self-paid for vaccines. The primary outcome was the first-dose HPV vaccine uptake, which was calculated using multivariable logistic regression, presented as crude/adjusted odds ratios (cORs/aORs) and 95% con dence intervals (CIs). Standard scales were used to assess the feasibility of the program. Results A total of 100 participants (50 in each arm) were recruited from Jan 4, 2022 to Feb 18, 2022. The HPV vaccine uptake rate was 98% (49/50) in the pay-it-forward arm and 82% (41/50) in the standard-of-care arm (cOR = 10.76, 95% CI: 1.31-88.47, P = 0.027; aOR = 12.12, 95% CI: 1.37-107.29, P = 0.025). The completion rate of full schedule of HPV vaccination in the two arms was 100% (49/49) and 95.1% (39/41), respectively. Of all 49 vaccinated girls in the pay-it-forward arm, 38 (77.6%) donated to support future participants, and the total donation accounted for 33.3% of prepaid subsidization. Among caregivers in the pay-it-forward arm, 97.6% (41/42) believed that this strategy was feasible. Conclusions The pilot showed feasibility and preliminary effectiveness of a pay-it-forward strategy to increase HPV vaccination rate. The high uptake rate in the standard-of-care arm is likely caused by the selection bias associated with the online dissemination approach and secured vaccine supply through the program. Further adaption of the intervention package and a population-based recruitment pathway are needed to better reflect local contexts and enhance the generalizability of the subsequent formal trial.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:15429. [PMID: 36497504 PMCID: PMC9735526 DOI: 10.3390/ijerph192315429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 11/17/2022] [Accepted: 11/17/2022] [Indexed: 06/17/2023]
Abstract
(1) Background: although mumps vaccines have been introduced in most countries around the world in recent years, mumps outbreaks have occurred in countries with high vaccination rates. At present, China remains the focus of the global fight against mumps. This study aims to observe the epidemic characteristics and spatial clustering patterns of mumps and to investigate the potential factors affecting the disease incidence, which could provide novel ideas and avenues for future research as well as the prevention and control of mumps. (2) Methods: we used ArcGIS software to visualize the spatial distribution and variation of mumps. Spatial autocorrelation analysis was applied to detect the spatial dependence and clustering patterns of the incidence. We applied the Spatial Durbin Panel Model (SDPM) to explore the spatial associations of ecological environmental factors with mumps. (3) Results: overall, the incidence rate showed a significant upward trend from 2014 to 2018, with the highest number of cases in the 10-15-year age group and from May to June. Geographically, the high incidence clusters were concentrated in southern regions, including Hunan, Hubei, Chongqing, Guizhou, Guangdong, and Guangxi. This study also found that mumps has a positive spatial spillover effect in the study area. The average temperature and GDP of the local and adjacent areas have a significant impact on mumps. The increase in PM2.5 contributes to the rise in the incidence of mumps in this region. (4) Conclusions: these results can offer some novel ideas for policymakers and researchers. Local meteorological conditions and economic levels can extend to surrounding areas to affect the occurrence of mumps, so regional cooperation becomes particularly important. We recommend investment of public health funds in areas with a high incidence of mumps and developing economies to reduce and control the incidence of mumps.

Abstract
Background Cancer is one of the major causes of death and the projection of cancer incidences is essential for future healthcare resources planning. Joinpoint regression and average annual percentage change (AAPC) are common approaches for cancer projection, while time series models, traditional ways of trend analysis in statistics, were considered less popular. This study aims to compare these projection methods on seven types of cancers in 31 geographical jurisdictions. Methods Using data from 66 cancer registries in the World Health Organization, projection models by joinpoint regression, AAPC, and autoregressive integrated moving average with exogenous variables (ARIMAX) were constructed based on 20 years of cancer incidences. The rest of the data upon 20-years of record were used to validate the primary outcomes, namely, 3, 5, and 10-year projections. Weighted averages of mean-square-errors and of percentage errors on predictions were used to quantify the accuracy of the projection results. Results Among 66 jurisdictions and seven selected cancers, ARIMAX gave the best 5 and 10-year projections for most of the scenarios. When the ten-year projection was concerned, ARIMAX resulted in a mean-square-error (or percentage error) of 2.7% (or 7.2%), compared with 3.3% (or 15.2%) by joinpoint regression and 7.8% (or 15.0%) by AAPC. All the three methods were unable to give reasonable projections for prostate cancer incidence in the US. Conclusion ARIMAX outperformed the joinpoint regression and AAPC approaches by showing promising accuracy and robustness in projecting cancer incidence rates. In the future, developments in projection models and better applications could promise to improve our ability to understand the trend of disease development, design the intervention strategies, and build proactive public health system.

Abstract
The goal of this research was to find noval transcription factors (TFs) that are involved in cervical carcinogenesis. The Gene Expression Omnibus (GEO) database was utilized to analyze ten cervical cancer datasets using the Robust Rank Aggregation (RRA) technique. Survival and differential expression were validated using GEPIA (Gene Expression Profiling Interactive Analysis). The transcriptional regulatory network and putative targets were built using Cytoscape. A real-time PCR (quantitative real-time polymerase chain reaction) experiment was used to confirm the mRNA expression. Using public cervical cancer single-cell RNA-sequencing (scRNA-seq), bulk TCGA-CESC RNA-seq, and microarray datasets, coexpression correlations between putative targets and TFs were confirmed. After combining the results of 10 datasets, 8 TFs, including EMX2 (Empty Spiracles Homeobox 2), were chosen among 385 robust DEGs. In the normal female reproductive tract, EMX2 is extensively expressed, but it is reduced in cervical cancer. Overexpression EMX2 suppresses the proliferation of HeLa cells. 12 potential targets of EMX2 were selected. Our research has revealed evidence that EMX2 acted as a tumor suppressor in cervical cancer and PDZRN3 might be possible target of EMX2 in cervical cancer. It might be a therapeutic target in the future.

Abstract
BACKGROUND DNA damage is a fundamental process that plays a considerable role in generating protein diversity. FANCI, loaded on the altered chromatin, plays a vital role in DNA damage. Abnormal FANCI expression is potentially associated with carcinogenesis.However, the biological role of FANCI in cervical cancer is yet to be determined. METHODS We analyzed FANCI expression via multiple gene expression databases. Genes co-expressed with FANCI and its regulators were identified using LinkedOmics. The correlations between FANCI and cancer immune infiltrates were investigated via Tumor Immune Estimation Resource (TIMER). RESULTS FANCI was found upregulated with amplification in tumor tissues of multiple cervical cancer cohorts. High FANCI expression was associated with poorer overall survival (OS). Functional network analysis suggested that FANCI regulates spliceosome, DNA replication, and cell cycle signaling via pathways involving several cancer-related kinases and the E2F family. In additional, FANCI expression was positively correlated with infiltrating levels of CD4+ T and CD8+ T cells, and neutrophils. FANCI expression also showed strong correlations with diverse immune marker sets in cervical cancer. CONCLUSION These findings suggested that FANCI is correlated with prognosis of and immune infiltration in cervical cancer, laying a foundation for further study of the immune regulatory role of FANCI in cervical cancer.

Abstract
BACKGROUND Globally, about 570,000 cases and 311,000 deaths of cervical cancer occurred in 2018. It was the leading cause of cancer-related deaths among women in Africa. The global mean age at death of cervical cancer was about 59 years. This study aimed to assess the determinants of cervical cancer mortality among cervical cancer patients attending in Tikur Anbessa Specialized Hospital (TASH). METHODS Institutional-based retrospective cohort study was conducted in the oncology center of TASH, Ethiopia, from March to April 2019. Data were extracted from patients' chart using structured checklist and analyzed using Stata 14.2. Cox regression was used to identify variables that affect the outcome variable. RESULT From the total of 2045 reviewed medical records of cervical cancer patients, 1057 medical records were found to be complete and included in this study. The incidence of mortality among cervical cancer patients was 15.6/100/years. Mortality was significantly increased with advanced age (adjusted hazard ratio (AHR) = 1.02, 95% CI (1.01-1.03)), comorbidity (AHR = 1.8, 95% CI (1.39-1.89)), being anemic (AHR = 1.42, 95% CI (1.07-1.89)), advanced stage (AHR = 1.63, 95% CI (1.24-2.13)), and being substance user (AHR = 2.71, 95% CI (2.08-3.53)). CONCLUSION The study revealed that the incidence of mortality within the cohort was 15.6/100/years. Mortality was significantly increased with advanced age, anemia, advanced stage, comorbidity, and using substances. It is better to give special attention to patients with anemia, advanced age, advanced stage, comorbidity, and substance usage. In addition, expanding cervical cancer early screening will decrease the mortality of patients.

Abstract
BACKGROUND Women's cancers, represented by breast and gynecologic cancers, are emerging as a significant threat to women's health, while previous studies paid little attention to the spatial distribution of women's cancers. This study aims to conduct a spatio-temporal epidemiology analysis on breast, cervical and ovarian cancers in China, thus visualizing and comparing their epidemiologic trends and spatio-temporal changing patterns. METHODS Data on the incidence and mortality of women's cancers between January 2010 and December 2015 were obtained from the National Cancer Registry Annual Report. Linear tests and bar charts were used to visualize and compare the epidemiologic trends. Two complementary spatial statistics (Moran's I statistics and Kulldorff's space-time scan statistics) were adopted to identify the spatial-temporal clusters. RESULTS The results showed that the incidence and mortality of breast cancer displayed slow upward trends, while that of cervical cancer increase dramatically, and the mortality of ovarian cancer also showed a fast increasing trend. Significant differences were detected in incidence and mortality of breast, cervical and ovarian cancer across east, central and west China. The average incidence of breast cancer displayed a high-high cluster feature in part of north and east China, and the opposite traits occurred in southwest China. In the meantime, the average incidence and mortality of cervical cancer in central China revealed a high-high cluster feature, and that of ovarian cancer in northern China displayed a high-high cluster feature. Besides, the anomalous clusters were also detected based on the space-time scan statistics. CONCLUSION Regional differences were detected in the distribution of women's cancers in China. An effective response requires a package of coordinated actions that vary across localities regarding the spatio-temporal epidemics and local conditions.

Abstract
High-risk human papillomavirus strains are widely known to be the causative agents responsible for cervical cancer development. Aggregated damage caused by papillomaviruses solely is estimated in at least 5% of all malignancies of the human body and 16% in cancers that affect the female genital area. Enhanced understanding of the complex issue on how the high extent of carcinogenicity is eventually formed due to the infection by the Papoviridae family would contribute to enhancing current prevention strategies not only towards cervical cancer, but also other HPV associated cancers. This review article is aimed at presenting the key points in two directions: the current cervical cancer prevention and related aspects of HPV behavior. Virtually all applied technologies related to HPV diagnostics and screening programs, such as HPV tests, colposcopy-based tests (VIA/VILI), conventional and liquid-based cytology, currently available are presented. Issues of availability, advantages, and drawbacks of the screening programs, as well as vaccination strategies, are also reviewed in the article based on the analyzed sources. The current point of view regarding HPV is discussed with emphasis on the most problematic aspect of the HPV family concerning the observed increasing number of highly carcinogenic types. Present trends in HPV infection diagnostics throughout the human fluids and tissues are also reported, including the latest novelties in this field, such as HPV assay/self-sample device combinations. Besides, a brief outline of the related prevention issues in Kazakhstan, the leading country of Central Asia, is presented. Kazakhstan, as one of the post-soviet middle-income countries, may serve as an example of the current situation in those terrains, concerning the implementation of globally accepted cervical cancer prevention strategies. Along with positive achievements, such as the development of a nationwide screening program, a range of drawbacks is also analyzed and discussed.

Abstract
To investigate the mechanism of small nucleolar RNA host gene 1 (SNHG1) in cervical cancer (CC). Methods: The expression of SNHG1, miR-194 and human cervical cancer oncogene (HCCR) in CC tissues and cells was detected using qRT-PCR and western blot. The interaction among the three molecules was measured using dual-luciferase reporter assay and RNA immunoprecipitation assay. The function of SNHG1 in CC cells was detected by CKK-8 assay and flow cytometry analysis. Results: SNHG1 was highly expressed in CC tissues and CC cell lines. Knockdown of SNHG1 inhibited CC cell proliferation and enhanced the ability of cell apoptosis. Mechanism investigation revealed that SNHG1 modulated HCCR expression via acting as a competing endogenous RNA of miR-194. Moreover, miR-194 inhibitor changed the effects of si-SNHG1 on CC cells growth. In vivo experiment, silencing of SNHG1 suppressed CC tumor growth by modulating miR-194/HCCR axis. Conclusion: Knockdown of SNHG1 inhibited CC progression by targeting HCCR via sponging with miR-194.

Abstract
Background Alternative splicing (AS) is a key factor in protein-coding gene diversity, and is associated with the development and progression of malignant tumours. However, the role of AS in cervical cancer is unclear. Methods The AS data for cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC) were downloaded from The Cancer Genome Atlas (TCGA) SpliceSeq website. Few prognostic AS events were identified through univariate Cox analysis. We further identified the prognostic prediction models of the seven subtypes of AS events and assessed their predictive power. We constructed a clinical prediction model through global analysis of prognostic AS events and established a nomogram using the risk score calculated from the prognostic model and relevant clinical information. Unsupervised cluster analysis was used to explore the relationship between prognostic AS events in the model and clinical features. Results A total of 2860 prognostic AS events in cervical cancer were identified. The best predictive effect was shown by a single alternate acceptor subtype with an area under the curve of 0.96. Our clinical prognostic model included a nine-AS event signature, and the c-index of the predicted nomogram model was 0.764. SNRPA and CCDC12 were hub genes for prognosis-associated splicing factors. Unsupervised cluster analysis through the nine prognostic AS events revealed three clusters with different survival patterns. Conclusions AS events affect the prognosis and biological progression of cervical cancer. The identified prognostic AS events and splicing regulatory networks can increase our understanding of the underlying mechanisms of cervical cancer, providing new therapeutic strategies.

Abstract
Background Despite the considerable efforts made to address the issue of brucellosis worldwide, its prevalence in dairy products continues to be difficult to estimate and represents a key public health issue around the world today. The aim of the present study was to better understand the epidemiology of this disease in mainland China. We set out to investigate the yearly spatial distribution and possible hotspots of the disease. Methods Human brucellosis data from mainland China between 2007 and 2016 were collected from the China Information System for Disease Control and Prevention. A geographic information system ArcGIS10.3 (ESRI, Redlands) was used to identify potential changes in the spatial and temporal distribution of human brucellosis in mainland China during the study period. These distributions were evaluated using three-dimensional trend analysis and spatial autocorrelation analyse. A gravity-center was used to analyse the migration track of human brucellosis. Results A total of 399,578 cases of human brucellosis were reported during the 10-year study period. The monthly incidence of brucellosis in China demonstrates clear seasonality. Spring and summer are the peak seasons, while May is the peak month for brucellosis. Three-dimensional trend analysis suggests that brucellosis is on the rise from south to north, and that the epidemic situation in northern China is more severe. Between 2007 and 2016, the overall migration distance of the brucellosis incidence gravity-center was 906.43 km, and the direction was southwest. However, the overall gravity center of brucellosis was still in the northern part of China. In the global autocorrelation analysis, brucellosis in China demonstrated a non-random distribution between 2013 and 2014, with spatial autocorrelation (Z > 1.96, P < 0.05) and a clustering trend, while no clustering trend was found from 2007 to 2012 or from 2015 to 2016. In the local autocorrelation analysis, a Low-Low cluster phenomenon was found in the south of China in 2013 and 2014. Conclusion Human brucellosis remains a widespread challenge, particularly in northern China. The hotspots highlight potential high-risk areas which may require special plans and resources for monitoring and controlling the disease.

Abstract
Effects and significance of formononetin on the expression levels of hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) in mouse cervical cancer tissue were investigated. The animal models of Balb/c nude mice with cervical cancer were established by the inoculation of HeLa cells, and randomly divided into positive control (n=10), cisplatin (n=15) and formononetin group (n=15). Mice were all sacrificed on the 31st day after administration, and their tumors were excised and weighed to calculate tumor inhibition rate. At the same time, their cancer tissues were obtained. RT-qPCR was used for detecting the mRNA expression levels of HIF-1α and VEGF, and western blotting for detecting the protein expression levels. During the medication intervention, mice in the formononetin group had no obvious adverse reactions, and were in good condition, whereas mice in the cisplatin group had poor appetite, drooping spirits and decreased activity. Mice in the cisplatin and the formononetin groups had significantly lower tumor mass and volume than those in the positive control group (P<0.05). The tumor inhibition rate of mice was 56.24% in the cisplatin group, and 50.17% in the formononetin group. Cervical cancer mice in the formononetin and the cisplatin groups had significantly lower mRNA and protein expression levels of HIF-1α and VEGF in tissues than those in the positive control group (P<0.05). Formononetin can inhibit the growth of cervical cancer and reduce the mRNA and protein expression levels of HIF-1α and VEGF in mouse cervical cancer. Formononetin has an inhibitory effect on cervical cancer tumors similar to that of cisplatin, but the former has smaller side effects, providing data for the clinical use in cervical cancer.

Abstract
BACKGROUND Aberrant spliced isoforms are specifically associated with cancer progression and metastasis. The cytoplasmic adaptor CRKL (v-crk avian sarcoma virus CT10 oncogene homolog-like) is a CRK like proto-oncogene, which encodes a SH2 and SH3 (src homology) domain-containing adaptor protein. CRKL is tightly linked to leukemia via its binding partners BCR-ABL and TEL-ABL, upregulated in multiple types of human cancers, and induce cancer cell proliferation and invasion. However, it remains unclear whether signaling adaptors such as CRKL could regulate alternative splicing. METHODS We analyzed the expression level of CRKL in 305 cervical cancer tissue samples available in TCGA database, and then selected two groups of cancer samples with CRKL differentially expressed to analyzed potential CRKL-regulated alternative splicing events (ASEs). CRKL was knocked down by shRNA to further study CRKL-regulated alternative splicing and the activity of SR protein kinases in HeLa cells using RNA-Seq and Western blot techniques. We validated 43 CRKL-regulated ASEs detected by RNA-seq in HeLa cells, using RT-qPCR analysis of HeLa cell samples and using RNA-seq data of the two group of clinical cervical samples. RESULTS The expression of CRKL was mostly up-regulated in stage I cervical cancer samples. Knock-down of CRKL led to a reduced cell proliferation. CRKL-regulated alternative splicing of a large number of genes were enriched in cancer-related functional pathways, among which DNA repair and G2/M mitotic cell cycle, GnRH signaling were shared among the top 10 enriched GO terms and KEGG pathways by results from clinical samples and HeLa cell model. We showed that CRKL-regulated ASEs revealed by computational analysis using ABLas software in HeLa cell were highly validated by RT-qPCR, and also validated by cervical cancer clinical samples. CONCLUSIONS This is the first report of CRKL-regulation of the alternative splicing of a number of genes critical in tumorigenesis and cancer progression, which is consistent with CRKL reported role as a signaling adaptor and a kinase. Our results underline that the signaling adaptor CRKL might integrate the external and intrinsic cellular signals and coordinate the dynamic activation of cellular signaling pathways including alternative splicing regulation.

Abstract
Objective: to detect the HPV types distribution both in general female population and in women with first diagnosed cervical cancer, including viral load in both groups. Methods: Qualitative detection and quantification of HPV was performed by PCR-Real time method based on the Russian equipment and test systems (“DNA-Technology” LLC, Russia). The DNA of low-risk (HPV 6, 11, 44) and possibly / potentially / high carcinogenic risk (HPV 16, 18, 26, 31, 33 , 35, 39, 45, 51, 52, 53, 56, 58, 59, 66, 68, 73, 82), a total of 21 types, were detected. Results: During the period of 2014-2017 total 1,166 clinically healthy women were tested for HPV, as well as 73 women diagnosed with CaCx. Overall prevalence of HPV in female population was determined as 25.0% (95% CI 22.3;27.7, p = 0.05). Top-5 leading HPV types: 16 (26.4%); 31 (10.1%); 51 (9.4%); 52 (9.0%); 6 (7.9%). Average viral load was 5.5±3.8 (CI 95% 5.1;5.9). In women diagnosed with CaCx ranking was as follows – 16 (54.1%), 31 (11.2%), 18 / 58 (5.1% each), 33 / 45 (4.1% each). Type 16 appeared to be one of the most significant risk factors of the CaCx development (p=0.00007, phi 0.35, Pierson’s X 2 15.9). Average viral load in patients with CaCx was 6.9±4.0 (95% CI 6.1;7.7). A reliable relationship between the cancer staging and the viral load was found (p = 0.043, n = 73). Domination of type 16 calls for urgent need the transition to HPV primary screening and resumption of immunization program discontinued in 2014. The study is registered in ISRCTN registry, No. ISRCTN71514910 (01.02.2018).

Abstract
Recently, some studies have placed additional research focus on microRNAs (miRNAs) in a bid to discover novel therapeutic approaches for cervical cancer (CC), which is one of the most common female reproductive tract malignancies with high rates of morbidity and mortality. Hence, the aim of the present study was to evaluate the ability of miR-129-5p to influence cell angiogenesis, invasion and migration by targeting ZIC2 through the Hedgehog signaling pathway in CC. Both CC and adjacent normal tissues were extracted from 87 eligible participating patients with CC. Measurements of the levels of miR-129-5p, mRNA and protein levels of ZIC2, sonic Hedgehog (Shh), Gli1, and Gli2 and levels of CXCL1, VEGF and Ang2 were determined accordingly. An angiogenesis assay was performed to evaluate cell angiogenesis in vitro, while a scratch test and transwell assay were adopted for cell invasion and migration determination. Lastly, tumor formation within nude mice was performed in order to analyze angiogenesis and tumor growth among the nude mice in vivo. The findings revealed that upregulation of miR-129-5p resulted in the decrease in the mRNA and protein levels of ZIC2, Shh, Gli1, Gli2, as well as reduced levels of CXCL1, VEGF and Ang2. Moreover, up-regulation of miR-129-5p was determined to inhibit CC cell angiogenesis ability in vitro, in addition to the processes of cell migration, and invasion. Finally, up-regulation of miR-129-5p was observed to inhibit the tumor growth and angiogenesis ability of nude mice in vivo. The results of the present study provided evidence suggesting that overexpressed miR-129-5p prevents angiogenesis and inhibits cell migration and invasion by means of negatively targeting ZIC2 through suppression of the Hedgehog signaling pathway in CC. Thus, highlighting the promise of miR-129-5p as a novel target for treating CC is promising.

Abstract
Cervical cancer remains a serious health problem till now, with nearly 500,000 women cases diagnosed each year around the world. Long noncoding RNA (lncRNA) is a novel class of RNA transcripts (>200 nucleotides in length) participating in gene transcription, cell proliferation, differentiation, and drug resistance. This study aimed to explore the regulatory relationship among lncRNA NCK1-AS1, miR-134-5p, and MutS protein homolog 2 (MSH2), so that the resistance against cisplatin in cervical cancer treatment could be better understood. Comprehensive lncRNA profiling analysis was performed to screen lncRNAs differentially expressed in cervical cancer. The expression patterns of miR-134-5p, NCK1-AS1, and MSH2 were evaluated in cancerous tissues and adjacent normal tissues obtained from 75 cervical cancer patients. Subsequently, anti-NCK1-AS1 small interfering RNA, miR-134-5p mimics, and miR-134-5p inhibitors were transfected into cervical cancer cells, and the effects of these transcripts on cisplatin resistance and cell apoptosis were investigated. The regulatory relationship among NCK1-AS1, miR-134-5p, and MSH2 was identified using a dual-luciferase reporter gene assay, and the results were further validated by RNA pull-down and RNA immunoprecipitation assays. Based on the microarray data of GSE63514 and GSE27678, NCK1-AS1 was upregulated in cervical cancer. Increased expression of NCK1-AS1, MSH2, and decreased expression of miR-134-5p were observed in cervical cancer tissues. In addition, NCK1-AS1 competitively bound to miR-134-5p to regulate MSH2. Therefore, si-NCK1-AS1 and miR-134-5p mimic both reduced MSH2 activity and increased cisplatin-induced apoptosis in cervical cancer cells. Taken together, NCK1-AS1 may become a novel target in improving the chemotherapeutic response and survival of cervical cancer patients.

Cancer Commun (Lond) 2018; 38:44. [PMID: 29970165 PMCID: PMC6029078 DOI: 10.1186/s40880-018-0308-x] [Citation(s) in RCA: 41] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2018] [Accepted: 06/04/2018] [Indexed: 12/17/2022] Open
Abstract
BACKGROUND The relationship between cancer and life expectancy is well established in both developed and developing countries. China is a vast country with significant geographical differences in population structure and healthcare, and thus provides a unique opportunity to analyze the complex relationship between life expectancy and cancer incidence and mortality rates. METHODS Cancer data were extracted for a total of 255 units (cities or counties) from the 2013 National Central Cancer Registry. Life expectancy data at the unit level were obtained from the National Centers for Disease Control and Prevention. Linear regression analysis was used to analyze the relationship between life expectancy and crude incidence and mortality rates of cancer. In a separate analysis, life expectancy was rated as low (< 76.0 years), middle (76-80 years), or high (> 80 years). RESULTS Overall, the cancer incidence and mortality rates positively correlated with life expectancy in both sexes (R at 0.37 and 0.50, P < 0.001). The correlation was significant for the following cancers: lung, colorectal, prostate, bladder and pancreas, as well as for lymphoma in men (R 0.36-0.58, P < 0.001), lung, breast, colorectal, thyroid, uterus, and ovary in women (R 0.18-0.51, P < 0.001). We failed to observe an association between upper gastrointestinal cancer and life expectancy. The number of cities/counties with low, middle and high life expectancy levels were 110, 101 and 44, respectively. The highest age-standardized cancer incidence rate was observed in areas with a high life expectancy level (192.83/100,000). The highest age-standardized mortality rate was in areas with the lowest life expectancy (118.44/100,000). Cancers of the stomach, liver and esophagus are major cancer types in areas with low and middle life expectancy. In contrast, areas with high life expectancy had high incidence and mortality rates of colorectal cancer, breast cancer in women and prostate cancer in men. CONCLUSIONS Longer life expectancy is associated with higher overall cancer incidence and mortality in China. The cancer pattern also varies substantially across areas with different life expectancy levels. Life expectancy levels must be considered when developing strategies to prevent and treat cancers.

[PMID: 29479954 PMCID: PMC5980914 DOI: 10.22034/apjcp.2018.19.2.319] [Citation(s) in RCA: 102] [Impact Index Per Article: 17.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/02/2017] [Indexed: 01/01/2023] Open
Abstract
Introduction: Cervical cancer rates vary across the world, being highest in Eastern Africa (including Zimbabwe) and lowest in Western Asia. It is the second most common type of cancer in women in the South East Asia region and a major cause of cancer deaths among women of low and middle income countries (LMICs) like Nepal. This review is an attempt to make a comprehensive report of prevalence, incidence and mortality of cervical cancer in LMICs. Methods: The review was conducted applying a computerized search with the Medical Subject Heading (MeSH) major topics “Cervical Cancer”, “Cervical neoplasm” “Epidemiology”, (“prevalence” OR “incidence” OR “mortality”) and “HPV” OR “Human papillomavirus” as MeSH subheading. The search limits were: language (“English”), LMICs, dates (articles published from “1st January 2000 to 31st December 2015”), and species (“Humans”). The search was supplemented by cross-referencing. Publications that met the inclusion criteria were included in the synthesis. Results: Among the 20 studies reviewed; seven were from Africa, seven from Asia, three from South America, and one each from North America, Europe and Oceania. The review found the highest reported age standardized incidence rate as 17.9/100,000/year in Zimbabwe in 2000 and the lowest as 0.11/100,000/year in China in 2006. One study of Nigeria revealed a cervical cancer prevalence of 5.0 per 1,000 in 2012 in the 25-64 year age group. Further, the highest reported age standardized mortality rate was 16/100,000/year in India in 2015 and the lowest 1.8/100,000/year in Colombia in 2013. In addition, coitarche, tobacco smoking, number of sexual partners and family history of cervical cancer were reported as significant risk factors. Conclusion: The study provides a review of reported prevalence, incidence and mortality of cervical cancer in LMICs from 1st January 2000 to 31st December 2015. The scarcity of information reveals a substantial need for further studies on cervical cancer prevalence, incidence and mortality with associated risk factors in LMICs.

Abstract
BACKGROUND Willingness to be vaccinated with human papillomavirus (HPV) vaccine among junior middle school students in China is not well understood. We conducted a cross-sectional study to assess awareness of HPV and the HPV vaccine and explore the factors associated with willingness to be vaccinated. METHODS First-year students from two junior middle schools in Jinan, China were selected by cluster sampling on December 28, 2015, December 26, 2016, and January 11, 2017, and a self-administered questionnaire was used to collect information. Multivariate logistic regression was conducted to explore the factors associated with willingness to be vaccinated with the HPV vaccine. RESULTS A total of 1021 junior middle school students participated in this survey. Only 15.5% of them had heard of HPV and 18.9% of them had heard of the HPV vaccine. Students who were willing to take the HPV vaccine in the future accounted for 66.9%. Factors associated with the HPV vaccination were: urban junior middle school students (AOR: 1.51, 95% CI: 1.09-2.09), female students (AOR: 1.90, 95% CI: 1.36-2.66), students surveyed in 2015 (AOR: 1.69, 95% CI: 1.26-2.28), regarding menstruation/spermatorrhoea as a normal physiological phenomenon (AOR: 1.64, 95% CI: 1.14-2.36), believing vaccination is an important way to prevent diseases (AOR: 1.36, 95% CI: 1.01-1.83), believing that the first vaccination should be in infancy (AOR: 1.41, 95% CI: 1.04-1.92), believing that cervical cancer is a concern for themselves (AOR: 1.95, 95% CI: 1.28-2.97), and having heard of HPV (AOR: 1.84, 95% CI: 1.13-2.98). CONCLUSIONS Awareness of HPV and the HPV vaccine among junior students was low, however willingness to be vaccinated was high. Education focusing on HPV-related knowledge in addition to sex education is needed to promote the coverage of the HPV vaccine.

Abstract
Numerous reports showed low levels of let-7 family in cervical cancer, acting as tumor suppressors by regulating multiple target genes. Genetic variants in the promoter of miRNA have been reported to influence individuals' susceptibility to human diseases. We aimed to investigate the association of rs10877887 and rs13293512 polymorphisms in the promoters of let-7 with risk of cervical squamous cell carcinoma (CSCC). A total of 331 patients with CSCC and 358 controls were included. Genotyping of rs10877887 was done using polymerase chain reaction-restriction fragment length polymorphism analysis. Genotyping of rs13293512 was performed using Taqman allelic discrimination. Relative expression of let-7 family was determined using quantitative real-time polymerase chain reaction. The rs10877887CC genotype was significantly associated with an increased risk of CSCC compared with the rs10877887TT (adjusted OR=2.11, 95% CI, 1.31-3.40, p-value=0.002) or rs10877887 TT/CT genotypes (adjusted OR=2.11, 95% CI, 1.34-3.31, p-value<0.001). Similarly increased risk of CSCC was observed when compared rs10877887T with rs10877887C allele (adjusted OR=1.35, 95% CI, 1.08-1.69, p-value=0.008). Combined analysis showed that individuals carrying the genotypes of rs10877887CC+rs13293512CC had a 4.78-fold higher risk to develop CSCC compared with those carrying the genotypes of rs10877887CT/TT+rs13293512CT/TT (OR=4.78, 95% CI, 1.78-12.84, p-value=0.001). Additionally, patients harboring rs10877887CC genotype had a lower level of let-7i in CSCC tissues (p-value=0.02). This observation indicates that rs10877887 may be a useful biomarker for the etiology of CSCC.

Abstract
Background: Cervical cancer is a major public health problem worldwide. There have been several studies
indicating that risk is associated with geographic location and that the incidence of cervical cancer has changed over
time. In Thailand, incidence rates have also been found to be different in each region. Methods: Participants were
women living or having lived in upper Northern Thailand and subjected to cervical screening at Maharaj Nakorn
Chiang Mai Hospital between January 2010 and December 2014. Generalized additive models with Loess smooth
curve fitting were applied to estimate the risk of cervical cancer. For the spatial analysis, Google Maps were employed
to find the geographical locations of the participants’ addresses. The Quantum Geographic Information System was
used to make a map of cervical cancer risk. Two univariate smooths: x equal to the residency duration was used in the
temporal analysis of residency duration, and x equal to the calendar year that participants moved to upper Northern
Thailand or birth year for participants already living there, were used in the temporal analysis of the earliest year. The
spatial-temporal analysis was conducted in the same way as the spatial analysis except that the data were split into
overlapping calendar years. Results: In the spatial analysis, the risk of cervical cancer was shown to be highest in
the Eastern sector of upper Northern Thailand (p-value <0.001). In the temporal analysis of residency duration, the
risk was shown to be steadily increasing (p-value =0.008), and in the temporal analysis of the earliest year, the risk
was observed to be steadily decreasing (p-value=0.016). In the spatial-temporal analysis, the risk was stably higher in
Chiang Rai and Nan provinces compared to Chiang Mai province. According to the display movement over time, the
odds of developing cervical cancer declined in all provinces. Conclusions: The risk of cervical cancer has decreased
over time but, in some areas, there is a higher risk than in the major province of Chiang Mai. Therefore, we should
promote cervical cancer screening coverage in all areas, especially where access is difficult and/or to women of lower
socioeconomic status.

Crk-like adapter protein is overexpressed in cervical carcinoma, facilitates proliferation, invasion and chemoresistance, and regulates Src and Akt signaling. Oncol Lett 2016; 12:3811-3817. [PMID: 27895735 PMCID: PMC5104173 DOI: 10.3892/ol.2016.5160] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2015] [Accepted: 07/01/2016] [Indexed: 12/18/2022] Open
Abstract
Overexpression of Crk-like (CrkL) adapter protein has been implicated in a number of types of human cancer. However, its involvement in human cervical carcinoma remains unclear. The present study aimed to explore the clinical significance and biological characteristics of CrkL in human cervical carcinoma. CrkL protein expression was examined in tissue samples from 92 cases of cervical carcinoma using immunohistochemistry, and was found to be overexpressed in 48.9% (45/92 cases). CrkL was transfected into HeLa and CaSki cervical carcinoma cell lines and its effects on biological behavior were examined. CrkL overexpression was revealed to promote cell proliferation, invasion and chemoresistance. In addition, CrkL overexpression increased the level of Src and Akt phosphorylation. Treatment with the Src inhibitor dasatinib eliminated the effect of CrkL on cell invasion. In conclusion, the current results demonstrate that CrkL is an oncoprotein overexpressed in cervical carcinoma which contributes to malignant cell growth and chemoresistance. In addition, the findings indicate that CrkL promotes cervical cancer cell invasion through a Src-dependent pathway.
