Article Synopsis
  • - The study compared robotic-assisted laparoscopic vaginectomy (RALV) and conventional laparoscopic vaginectomy (CLV) for patients with vaginal high-grade squamous intraepithelial lesions (HSIL), finding RALV to have less blood loss, fewer complications, and shorter recovery times.
  • - Both surgical methods showed similar high rates of HPV infection regression and vaginal HSIL regression after treatment, indicating effectiveness for managing the condition.
  • - RALV was associated with significantly higher hospital costs compared to CLV, suggesting that while RALV may offer some operational advantages, it may not be the most cost-effective option.

Background: To summarise the application of minimally invasive surgery for female primary pelvic retroperitoneal tumours (PPRTs).

Methods: The clinical data of PPRT in a hospital between January 2017 and August 2022 were retrospectively collected. Surgical outcomes for cystic and solid tumours and two minimally invasive techniques were compared.

Article Synopsis
  • * We identified 22 prognostic stemness-related genes (PSRGs) using methods like edgeR and WGCNA, which helped us develop a prediction model for metastatic ovarian cancer.
  • * Key interactions in a network specific to ovarian cancer metastasis were revealed, including a notable connection between transcription factors NR4A1 and EGR3 and the TNFα signaling pathway, with Thioridazine identified as a potential inhibitor for stemness-related signatures.

Steroid saponins are secondary metabolites with multiple medicinal values that are found in large quantities in natural medicines, especially Vernonia amygdalina, a famous nature medicine for the treatment of tonsillitis, diabetes, pneumonia. The current study was designed to combine molecular networking (MN) with diagnostic ions for rapid identification of Δ stigmastane-type saponins which were the α-glucosidase inhibitory active substances in V. amygdalina.

Vernoramyosides A-F (1-6), six new Δ stigmastane-type steroid saponins, along with four known analogues (7-10) were isolated from the leaves of Vernonia amygdalina Delile (Compositae). Their structures were determined by the combination of NMR, ECD and HR-ESI-MS data. These compounds all possessed highly oxidized side chain and a γ-lactam or α,β-unsaturated five-membered lactone ring.

Six undescribed 1,8,9-phragmalin limonoid orthoesters (chukorthoesters A-F, 1-6) and two undescribed mexicanolide-type limonoids (ivorenoids H and I, 7 and 8), together with ten known limonoids, were isolated from the seeds of common wood-source and greening plants Chukrasia tabularis A. Juss. Their chemical structures were elucidated using HR-ESI-MS, 1D and 2D NMR spectroscopic analysis, and that of 1 along with absolute configuration was confirmed by X-ray diffraction experiment with Cu Kα radiation.

Background: Previous studies have suggested that metformin may be useful for preventing and treating endometrial cancer (EC), while the results have been inconsistent. This systematic review and meta-analysis aimed to investigate the association between metformin use and risk and prognosis of patients with EC.

Methods: PubMed, Embase, and the Cochrane Library databases were searched for observational studies evaluating the effect of metformin on EC prevention or treatment.
