To identify a new drug candidate for treating endometriosis which has fewer side effects, a new polymeric nanoparticle gene delivery system consisting of polyethylenimine-grafted chitosan oligosaccharide (CSO-PEI) with hyaluronic acid (HA) and small interfering RNA (siRNA) was designed. There was no obvious difference in sizes observed between (CSO-PEI/siRNA)HA and CSO-PEI/siRNA, but the fluorescence accumulation in the endometriotic lesion was more significant for (CSO-PEI/siRNA)HA compared with CSO-PEI/siRNA due to the specific binding of HA to CD44. In addition, the (CSO-PEI/siRNA)HA nanoparticle gene therapy significantly decreased the endometriotic lesion sizes with atrophy and degeneration of the ectopic endometrium. The epithelial cells of ectopic endometrium from rat models of endometriosis showed a significantly lower CD44 expression than control after treatment with (CSO-PEI/siRNA)HA. Furthermore, observation under an electron microscope showed no obvious toxic effect on the reproductive organs. Therefore, (CSO-PEI/siRNA)HA gene delivery system can be used as an effective method for the treatment of endometriosis.

Endometriosis and adenomyosis are debilitating gynecological conditions that severely affect the quality of life of women. Traditional diagnostic and treatment methods, including laparoscopic surgery and hormonal therapy, face significant limitations such as incomplete lesion detection, high recurrence rates, and adverse side effects. Emerging bioengineering technologies offer promising solutions for precise diagnosis and therapy of these diseases.

As a chronic gynecological disease, endometriosis is defined as the implantation of endometrial glands as well as stroma outside the uterine cavity. Proliferation is a major pathophysiology in endometriosis. Previous studies demonstrated a hormone named melatonin, which is mainly produced by the pineal gland, exerts a therapeutic impact on endometriosis.

Rationale: Spontaneous uterine rupture, although rare, is a life-threatening obstetric emergency with a high maternal and fetal mortality rate. It can occur without warning, leading to severe complications, including hemorrhage, shock, and fetal demise. The risk factors contributing to uterine rupture are diverse and include a history of uterine surgery (such as cesarean section), trauma to the uterus, abnormal uterine contractions during labor, and underlying conditions like adenomyosis.

Endometriosis is a chronic inflammatory condition characterized by the presence of endometrium-like tissue outside the uterus, primarily affecting pelvic organs and tissues. In this study, we explored platelet activation in endometriosis. We utilized the STRING database to analyze the functional interactions among proteins previously identified in small extracellular vesicles (EVs) isolated from the peritoneal fluid of endometriosis patients and controls.
