Objective: To clarify the role of LINC00665 in ovarian cancer (OC) progression and the possible mechanism. Methods: LINC00665 levels in OC tissues and cell lines were detected by qRT-PCR. The correlation between LINC00665 and clinicopathologic characteristics of OC patients was assessed. Biological functions of OC cell phenotypes influenced by LINC00665 were examined by CCK-8, colony formation and Transwell assay. Dual-luciferase reporter assay and RIP assay were conducted to verify the interaction between LINC00665 and its downstream target. Results: LINC00665 was upregulated in OC and linked to poor prognosis. Knockdown of LINC00665 blocked malignant proliferative, migratory and invasive functions of OC cells. By competitively binding miRNA-34a-5p, LINC00665 abolished the inhibitory effect of miR-34a-3p on its downstream gene E2F3, thus promoting OC progression. Conclusion: LINC00665/miRNA-34a-5p/E2F3 axis is involved in OC progression, providing novel insights into the clinical treatment of OC.
Background There have been a large number of epidemiologic studies regarding the association between genetic polymorphisms in DNA repair genes and onset of cervical cancer. However, results are inconsistent. Methods Articles published before June 2021 and regarding genetic polymorphisms in DNA repair genes and cervical cancer were searched in following databases: PubMed, Web of Science, Google Scholar, and CNKI. With at least three articles for each polymorphism, we made meta‐analysis to compute multivariate odds ratios (ORs) and their 95% confidence intervals (CIs). Results The present study showed significant associations between XRCC1 Arg399Gln polymorphisms and risk of cervical cancer in Asian, whereas no significant association between them were showed in Caucasian (Asian: GA vs. GG: OR = 1.27, 95%CI 1.06–1.52; AA vs. GG: OR = 1.91, 95%CI 1.29–2.83; GA + AA vs. GG: OR = 1.36, 95%CI 1.12–1.65; AA vs. GG + GA: OR = 1.66, 95%CI 1.17–2.37; Caucasian: GA vs. GG: OR = 1.08, 95%CI 0.83–1.41; AA vs. GG: OR = 2.18, 95%CI 0.75–6.31; GA + AA vs. GG: OR = 1.23, 95%CI 0.85–1.78; AA vs. GG + GA: OR = 1.70, 95%CI 0.69–4.18). In addition, there were significant associations between ERCC2 rs13181 polymorphisms and risk of cervical cancer in Asian (AC vs AA: OR = 0.53, 95%CI 0.37–0.75, I2 = 0.0%, p value of Q test = 0.847; AC + CC vs AA: OR = 0.50, 95%CI 0.36–0.70, I2 = 0.0%, p value of Q test = 0.856). Conclusions The meta‐analysis showed that there were significant associations between XRCC1 Arg399Gln and ERCC2 rs13181 polymorphisms and risk of cervical cancer.
Objective. The aim of the present study is to investigate the rules and characteristics of the clinical administration of traditional Chinese medicine (TCM) in the treatment of polycystic ovary syndrome (PCOS) using data mining methods. Method. Medical cases of well-known contemporary TCM doctors treating PCOS were collected from the China National Knowledge Infrastructure, Chinese Biomedical Literature Service System, Wanfang, Chinese Scientific Journals Database, and PubMed; the data were then characterized, and a standardized database of medical cases was built. This database was used to (1) count the frequency of syndrome types and the herbs used in medical cases by data mining methods and (2) analyze drug association rules and systematic clustering methods. Results. A total of 330 papers were included, involving 382 patients and a total of 1,427 consultations. The most common syndrome type was kidney deficiency; sputum stasis was the core pathological product and causative factor. A total of 364 herbs were used. Among them, 22 herbs were used >300 times, including Danggui (Angelicae Sinensis Radix), Tusizi (Semen Cuscutae), Fuling (Poria), Xiangfu (Nutgrass Galingale Rhizome), and Baizhu (Atractylodis Macrocephalae Rhizoma). Additionally, 22 binomial associations were obtained from the analysis of association rules; five clustering formulae were obtained via the analysis of high-frequency drug clusters; and 27 core combinations were obtained by k-means clustering of formula. Conclusion. In the treatment of PCOS, TCM is primarily employed as a combination approach involving tonifying the kidneys, strengthening the spleen, eliminating damp and dissolving phlegm, activating blood circulation, and resolving blood stasis. The core prescription is primarily a compound intervention based on the Cangfu Daotan pill, Liuwei Dihuang pill, and Taohong Siwu decoction.
Background: Persistent infection with high-risk human papilloma virus (HPV) is the main cause of cervical cancer. Cervical precancerous lesions last for long and are reversible. Thus, the effective way to prevent cervical cancer is to make a timely diagnosis and administer treatment in the precancerous stage. This study sought to explore the evaluation of cervical cytology by a ThinPrep cytologic test (TCT) combined with HPV typing in patients with cervical diseases, and the relationship between HPV typing and the pathological results of patients with atypical squamous cells of undetermined significance (ASCUS). Methods:The medical records of 414 patients who received outpatient treatment at the Suzhou Hospital of Traditional Chinese Medicine from February 2020 to February 2022. The pathological results of all cases were followed-up, and data on patients' age, menopause, pregnancy status, birth status, HPV typing, and HPV infection status were collected and statistically analyzed. The positive predictive value, negative predictive value, sensitivity, and specificity of the 2 detection methods were calculated. The factors associated with ASCUS pathological results were analyzed by logistic regression.Results: Among the 414 patients, 230 had positive vaginal tissue biopsy results, taking this as the gold standard, the diagnostic value of TCT and HPV were examined and compared. HPV typing had a slightly higher sensitivity and positive predictive value than TCT; however, the 2 methods combined had the highest sensitivity and positive predictive value. The univariate analysis showed that the age, HPV infection, and HPV typing in the group of chronic cervicitis differed significantly from the group of cervical intraepithelial neoplasia (CIN) II+/cervical carcinoma (P<0.05). The logistic regression analysis showed that HPV infection, being HPV-16 positive, and being HPV-18 positive were risk factors of ASCUS disease (P<0.05).Conclusions: Compared to individual detection methods, TCT combined with HPV typing had a higher detection rate and screening accuracy for cervical diseases, and had the highest sensitivity and positive predictive value. HPV infection, being HPV-16 positive, and being HPV-18 positive are risk factors for ASCUS lesions. HPV typing detection can improve the accuracy of ASCUS shunt diagnosis and provide a reliable basis for the establishment of ASCUS shunt management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
