Abstract Background Endometriosis is intricately linked to metabolic health. The Cardiometabolic Index (CMI), a novel and readily accessible indicator, is utilized to evaluate metabolic status. This study seeks to investigate the potential correlation between CMI and endometriosis. Methods Data from four consecutive survey cycles of the National Health and Nutrition Examination Survey (NHANES) conducted between 1999 and 2006 were utilized. This included adult females with self-reported diagnoses of endometriosis and complete information required for calculating the CMI. The calculation formula for CMI is Triglycerides(TG) / High-density lipoprotein cholesterol (HDL-C) × WHtR (WHtR = waist circumference / height). A multivariable logistic regression model was employed to investigate the linear association between CMI and endometriosis. Subgroup analyses were performed to explore potential influencing factors. Additionally, the linear relationship was validated using restricted cubic spline (RCS) curve plotting and threshold effect analysis. Results This study, based on the National Health and Nutrition Examination Survey (NHANES), included a cohort of 2,224 adult women. The multivariable logistic regression analysis demonstrated that in the fully adjusted model, individuals with the highest CMI exhibited a 78% elevated likelihood of endometriosis compared to those with the lowest CMI (OR = 1.78; 95% CI, 1.02–3.11, P 0.05), except for the subgroup stratified by stroke status (P 0.67 (OR = 1.20; 95% CI, 1.05–1.37, P

IntroductionPhosphorus (P) fertilizer is critical to maintain a high yield and quality of alfalfa (Medicago sativa L.). There are several fertilizer types and soil types in China, and the application of a single type of P fertilizer may not be suitable for present-day alfalfa production.MethodsIn order to select the optimal combination of alfalfa and soil type and fertilizer type for improving P utilization efficiency. We conducted a greenhouse pot experiment, calcium superphosphate (SSP), diammonium phosphate (DAP), ammonium polyphosphate (APP), potassium dihydrogen phosphate (KP), and no-fertilizer control treatments were applied to alfalfa in sandy and saline-alkali soils. The response of alfalfa root morphology and rhizosphere processes to different P fertilizers was investigated.Results and discussionThe results showed that shoot biomass of alfalfa was slightly higher in sandy soil than in saline–alkali soil. Shoot biomass of alfalfa increased by 223%-354% in sandy soil under P treatments compared with the control, and total root length increased significantly by 74% and 53% in DAP and SSP treatments, respectively. In saline–alkali soil, alfalfa shoot biomass was significantly increased by 229% and 275% in KP and DAP treatments, and total root length was increased by 109% only in DAP treatment. Net P uptake of alfalfa in DAP treatment was the highest in both soils, which were 0.73 and 0.54 mg plant-1, respectively. Alfalfa shoot P concentration was significantly positively correlated with shoot and root biomass (P < 0.05, 0.01 or 0.001) whereas negatively correlated with acid phosphatase concentration (P < 0.05). Improvement of plant growth and P uptake induced by P fertilizer application was greater in sandy soil than in saline–alkali soil. DAP and KP was the most efficient P fertilizers in both sandy soil and saline–alkali soil.

Purpose: To determine the effect of cirsilineol on the proliferation and migration of endometriotic cells. Methods: Human endometriotic epithelial cells 12Z were treated with 5, 10 and 20 μM cirsilineol, respectively. Cell proliferation was evaluated using BrdU incorporation assay whereas wound healing assay was used to investigate cell migration, and cell invasion was assessed by Transwell assay. Cell cycle was investigated using flow cytometry while protein expression and phosphorylation levels of p65 and IκBα were evaluated by Western blot. Results: Treatment with cirsilineol at either 10 μM or 20 μM resulted in a significant reduction in cell proliferation and cell cycle arrest at the G2/M phase (p < 0.05). Moreover, cirsilineol weakened cell migration and invasion in 12Z cells, but did not alter the expression of p65. However, it significantly downregulated the phosphorylation of p65 and increased the expression of IκBα, while attenuating the phosphorylation level of IκBα (p < 0.05). Furthermore, 5 μM cirsilineol did not show any significant effects on these cellular activities, suggesting the activity of cirsilineol in 12Z cells is dose-dependent. Conclusion: Cirsilineol inhibits cell proliferation, induces cell cycle arrest, suppresses migration and invasion of endometriotic epithelial cells by regulating NF-κB pathway. Thus, cirsilineol might be a potential therapeutic candidate for endometriosis treatment. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the effect of a traditional Chinese medicine, Jing Tong Yu Shu (JTYS) on endometriosis in a rat surgical model. Methods: Endometriosis was induced in 40 female rats. The rats were randomly divided into 4 groups: three JTYS groups given different doses of the drug, and a saline group. After four weeks of treatment with JTYS, the volume of the endometriotic explants was measured, and the levels of IL-1β and IL-6 in peritoneal fluid and serum were determined by enzyme-linked immunosorbent assay (ELISA). The production of cytokine IL-1β and IL-6 by peritoneal macrophages was also measured for each group. Results: JTYS treatment brought about regression of implants and inhibition of IL-1β and IL-6 production in a dose-dependent manner, with high-dose JTYS eliciting 66.76 % reduction in mean endometriotic explant volume. Plasma and peritoneal fluid levels of IL-1β and IL-6 were significantly lower in the high-dose JTYS group than in the saline group (p < 0.05). However, JTYS treatment significantly inhibited IL-1β and IL-6 production in peritoneal macrophages (p < 0.05). Conclusion: These results suggest that JTYS treatment leads to regression of endometriotic lesions in rat. Thus, JTYS has the potential to be developed into a new drug for the treatment of endometriosis. [ABSTRACT FROM AUTHOR]
