Obesity is a chronic low-grade inflammation and a risk factor for diseases such as diabetes, hypertension, dyslipidemia, and malignant tumors, demonstrating an increasingly grim development situation. The nuclear factor-kappa B (NF-κB) signaling pathway is a key signaling pathway involved in the immune response and inflammatory response. In obese individuals, the expression of NF-κB is overactivated, which leads to abnormal inflammatory responses in the body. Therefore, it is expected to alleviate inflammation and treat obesity by regulating the NF-κB signaling pathway, which has been proven effective by a large number of studies. The available studies on the NF-κB signaling pathway mostly focus on tumors, and there is no systematic review of the mechanism of this pathway in mediating obesity and the traditional Chinese medicine (TCM) treatment. We reviewed the research progress in the pathological and physiological processes of obesity mediated by NF-κB signaling pathway and TCM treatment, aiming to give insights into the clinical treatment of obesity with TCM and provide reference targets and research directions for exploring the biological foundations and the development of new TCM preparations.

The safety, economic benefit, and psychological satisfaction of day surgery was analyzed. Results A total of 42 women with breast cancer were included in the retrospective study and 39 women with breast cancer were included in the prospective study. In both prospective and retrospective studies, the mean age of patients in both groups were <50 years. There were only statistical differences between the two groups in the aspects of hypertension (P=0.022), neoadjuvant chemotherapy (P=0.037) and postoperative pathological estrogen receptor (P=0.033) in the prospective study. In postoperative complications, there were no statistical differences in the surgical-related complications or anesthesia-related complications between the two groups in either the prospective study or the retrospective study (P>0.05). In terms of the overall cost, we found that the day surgery group was more economical than the ward surgery group in the prospective study (P=0.002). There were no statistical differences in postoperative psychosocical well-being, sexual well-being, satisfaction with breasts or chest condition between the two groups (P>0.05). Conclusion It is safe and reliable to carry out breast conserving surgery in day surgery center under strict management standards, which can save medical costs and will not cause great psychological burden to patients.

ObjectiveTo explore the mechanism by which Ruyan Neixiao cream (RUC) induces ferroptosis in breast precancerous lesion (BPL) cells, and to enrich the theoretical foundation for its use in the treatment of BPL. MethodsThe inhibition of cell proliferation by 1%, 2%, and 4% concentrations of Ruyanneixiao Cream transdermal solution (RUT) was assessed using cell counting kit-8 (CCK-8) and a colony formation assay. Reactive oxygen species (ROS) were measured using the DCFH-DA probe, and the levels of ferrous ions (Fe2+), glutathione (GSH), and malondialdehyde (MDA) were determined using appropriate kits. Lipid peroxidation was detected with the C11-BODIPY581/591 fluorescent probe. The expression of nuclear factor E2-related factor 2 (Nrf2), solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) proteins was analyzed by Western blot. The BPL rat model was constructed using 2,2′-bis(hydroxymethyl)butyric acid (DMBA) combined with estrogen and progesterone, and the rats were treated with RUC for external application. After the 12th cycle, the rats were euthanized, and histopathological changes in breast tissue were observed by hematoxylin-eosin (HE) staining. Fe2+ and MDA levels in breast tissue were measured using corresponding kits. The expression of Nrf2, SLC7A11, and GPX4 proteins in BPL rat breast tissue was detected by immunohistochemistry (IHC) and Western blot. ResultsCompared with the matrix group, the cell viability of MCF-10AT cells in the 1%, 2%, and 4% RUT groups was significantly reduced (P<0.05) in a concentration-dependent manner, with the 24-hour half inhibitory concentration (IC50) being 2.23%. Compared with the 4% RUT group, cell viability in the RUT + Fer-1 group was significantly increased (P<0.05). Compared with the matrix group, the colony formation rates of MCF-10AT cells in the 1%, 2%, and 4% RUT groups were significantly decreased (P<0.05). Compared with the 4% RUT group, the cell colony formation rate of the RUT + Fer-1 group was significantly increased (P<0.05). Compared with the matrix group, the levels of ROS and Fe2+ in the 1%, 2%, and 4% RUT groups were significantly increased (P<0.05), while GSH levels were significantly decreased (P<0.05), and MDA and lipid peroxidation levels were significantly increased (P<0.05). Compared with the 4% RUT group, ROS and Fe2+ levels in the RUT + Fer-1 group were significantly reduced (P<0.05), while GSH levels were significantly increased (P<0.05), and MDA and lipid peroxidation levels were significantly reduced (P<0.05). Compared with the matrix group, the protein expression levels of Nrf2, SLC7A11, and GPX4 in the 1%, 2%, and 4% RUT groups were significantly decreased (P<0.05). Compared with the 4% RUT group, the protein expression levels of Nrf2, SLC7A11, and GPX4 in the RUT + Fer-1 group were significantly increased (P<0.05). In the in vivo experiment, compared with the matrix group, the breast tissue histopathological status of the BPL rats in the RUC group was effectively improved, with less dilatation of the mammary ducts and more orderly duct arrangement. No pathological morphology indicative of invasive cancer was observed. Compared with the matrix group, Fe2+ and MDA levels in the mammary tissue of the RUC group were significantly increased (P<0.05). Compared with the matrix group, the protein expression levels of Nrf2, SLC7A11, and GPX4 in the mammary tissue of the RUC group were significantly reduced (P<0.05). ConclusionRUC may induce ferroptosis in BPL cells by inhibiting the Nrf2/SLC7A11/GPX4 signaling pathway, increasing Fe2+ accumulation, and promoting lipid peroxidation.
