Article Synopsis
- The study investigated how the vaginal microenvironment affects HPV infection and the role of vitamin D in this context, using data from 512 participants categorized into HPV positive and negative groups.
- It was found that the high-risk HPV (HR-HPV) group had higher abnormal rates of certain microbial and biochemical markers compared to the HPV negative group, indicating a link between these factors and HPV infection.
- Vitamin D supplementation showed promise in reducing the persistence of HR-HPV after treatment, while also improving overall nutritional and metabolic health by lowering inflammation and other risk factors.
Article Synopsis
- Endometrial cancer (EC) is a growing global health issue, and long noncoding RNA NEAT1 has been identified as an oncogene linked to various cancers, including EC.
- In the study, NEAT1 was found to be upregulated, while microRNA (miR)-202-3p was downregulated in EC cells, indicating that NEAT1 may promote cell growth and invasiveness in EC.
- The findings suggest that NEAT1 enhances EC progression by sponging miR-202-3p to boost TIMD4 expression, indicating a potential new avenue for treatment strategies targeting this pathway.
Identifying the transformations of heavy metal in different media is a scientific issue, and geographical detector is applied to evaluate the spatiotemporal stratified heterogeneity mechanisms for heavy metals in the Yangtze River Estuary. Heavy metal concentrations in water and sediment were consistent with lognormal distributions. Their concentrations were organized into four classes.

Aim: The aim of our study was to estimate the prevalence and risk factors of common female lower genital tract infections (LGTIs) among married women in Beijing.
Material & Methods: A community-based, cross-sectional survey was conducted among married women aged 25-54years. All subjects were interviewed, followed by gynecological examination and laboratory tests.
The purpose of this study is to examine knowledge of cervical cancer and the relationship between knowledge of human papillomavirus (HPV) infection and cervical disease in a largely representative Beijing population. A questionnaire-based survey was conducted in a Beijing population sample of married women ages 25 to 54 years (n = 6,339), evaluating knowledge and relevant factors with regard to cervical cancer. Knowledge levels were low; only 52.

Article Synopsis
- A study was conducted to assess the prevalence and risk factors for common lower reproductive tract infections (RTIs) among women aged 25 - 54 in Beijing, focusing on bacterial vaginosis, trichomoniasis, and vulvovaginal candidiasis.
- Out of 6,339 women, the overall RTI prevalence was found to be 11.4%, with bacterial vaginosis being the most common at 8.7%, and factors significantly linked to infections included age, profession, income, number of sex partners, and condom use.
- The findings indicated that the prevalence of these infections in Beijing was lower compared to other regions in China, with specific demographics at higher risk, particularly women aged 30
