OBJECTIVE: Approximately 20% of adenomyosis cases occur in women under 40 years of age [1]. Although LNG-IUD is the first-line medical therapy, its treatment failure is closely associated with uterine volume [2] with expulsion rates reporte…

Despite ongoing challenges in developing effective non-surgical and non-hormonal treatments for endometriosis, the psychological manifestations of the disease-particularly anxiety-remain comparatively underexplored. In this study, a hydroge…

BACKGROUND: Endometriosis severely affects women's physical and mental health; it is particularly important to find targets for the treatment and diagnosis of endometriosis. METHOD: This research aimed to investigate the circRNA expression…

BackgroundRetroperitoneal ectopic pregnancy (REP) is a rare form of ectopic pregnancy, in which fertilised eggs are implanted in the retroperitoneal cavity. Due to its atypical location and non-specific symptoms, REP is often misdiagnosed, …

BackgroundGenome instability plays a crucial role in promoting tumor development. Germline mutations in genes responsible for DNA repair are often associated with familial cancer syndromes. A noticeable exception is the CHEK1 gene. Despite …

Early pregnancy loss (EPL) is a common event in human reproduction and is classified into histological subtypes such as hydropic abortion (HA) and hydatidiform moles, including complete hydatidiform moles (CHMs) and partial hydatidiform mol…

BACKGROUND: Primary vaginal cancer is a rare condition. Some studies have revealed an increased risk of vaginal cancer among patients who have undergone hysterectomy for premalignant and malignant cervical disease. However, there is limited…

Ovarian cancer is one of the most lethal malignant tumors, characterized by high incidence and poor prognosis. Patients relapse occurred in 65-80% after initial treatment. To date, no effective treatment has been established for these patie…

Study questionWhat are the dynamic expression features of plasma microRNAs (miRNAs) during the peri-implantation period in women with successful pregnancy via single frozen-thawed blastocyst transfer?Summary answerThere is a significant cha…

Stem cells have shown great potential functions for tissue regeneration and repair because of their unlimited self-renewal and differentiation. Stem cells reside in their niches, making them a hotspot for the development and diagnosis of di…

BackgroundHigh-grade serous tubo-ovarian cancer (HGSTOC) is characterised by extensive inter- and intratumour heterogeneity, resulting in persistent therapeutic resistance and poor disease outcome. Molecular subtype classification based on …

Many gene products exhibit great structural heterogeneity because of an array of modifications. These modifications are not directly encoded in the genomic template but often affect the functionality of proteins. Protein glycosylation plays…

BackgroundThe ovary is an important organ of the female reproductive system, which produces oocytes and secretes reproductive hormones. Ovaries have complex dual blood supplies with their blood supply being the core component to protect and…

Objective: To investigate the MRI manifestations of congenital vaginal atresia, analyze its imaging features, and improve the understanding of the disease. Methods: MRI findings and clinical data of 12 patients with congenital vaginal atres…

SUMMARY The human uterus is a highly dynamic tissue that undergoes repeated damage repair and regeneration during the menstrual cycle, which make it ideal model to study tissue regeneration and pathological process. Stem/progenitors were sp…

To mine possibly hidden causal single-nucleotide polymorphisms (SNPs) of melanoma, we investigated the association of SNPs in 76 M/G1 transition genes with melanoma risk using our published genome-wide association study (GWAS) data set with…

OBJECTIVE: To study the impact of bcl-2 and p53 protein expressions on the malignant transformation of ovarian endometriosis. METHODS: Immunohistochemical technique was used to detect the bcl-2 and p53 protein expressions in: endometriosis …

OBJECTIVE: To study clinicopathologic characteristics, treatment and prognostic factors of malignant transformation of endometriosis of the ovary. METHODS: From 1981 to 1999, a total of 25 patients with malignant transformation of endometri…
