Objective:
To investigate the ferroptosis induced by sesamin in triple-negative breast cancer ( TNBC) 4T1 cells and its underlying mechanism .
Methods:
The binding energy of sesamin with glutathione peroxidase 4 (GPX4) , solute carrier family 7 member 11 ( SLC7A11) , and P53 was analyzed by molecular docking. Mouse TNBC cell line 4T1 was used as a model . Different concentrations of sesamin were administered to 4T1 cells . The effect of sesamin on cell viability was assessed using the cell counting kit 8 (CCK-8) . Transwell assay was used to evaluate the effect of sesamin on cell migration and invasion . The contents of Fe2 + , malondialdehyde (MDA) , and reduced glutathione (GSH) in the cells were measured using kits . 2 ′,7 ′-dichlorofluorescein diacetate (DCFH-DA) probe was employed to detect the content of reactive oxygen species (ROS) in cells . Real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) and Western blot were performed to evaluate the expression of GPX4 , SLC7A11 , and P53 at mRNA and protein levels .
Results:
The binding energies of sesamin with GPX4 , SLC7A11 and P53 were - 21 . 46 , - 21 . 67 , and - 27 . 03 kJ/mol , respectively . Compared with the control group , the viability of 4T1 cells in different concentrations of sesamin groups decreased gradually ( P < 0. 001) , and the migration and invasion ability of 4T1 cells in 20 , 40 , and 80 μmol/L sesamin groups decreased gradually (all P < 0. 001) . Compared with the control group , the contents of Fe2 + , MDA , and ROS in 4T1 cells of 20 , 40 , and 80 μmol/L sesamin groups increased , and the content of GSH decreased . Compared with the control group , the mRNA and protein expression of GPX4 and SLC7A11 in 4T1 cells in the sesamin treatment group decreased , and the mRNA and protein expression of P53 increased ( all P < 0. 001) .
Conclusion
Sesamin may induce the ferroptosis in 4T1 cells through P53/SLC7A11 /GPX4 pathway .

Objective: To investigate the efficacy, nursing characteristics, and management of different desensitization strategies before allogeneic hematopoietic stem cell transplantation (allo-HSCT) among patients with high level of human leukocyte antigen (HLA) antibodies. Methods: A retrospective analysis was conducted on 82 patients with high levels of HLA antibodies who underwent allo-HSCT at the First Affiliated Hospital of Soochow University and Suzhou Hopes Hematonosis Hospital between January 2020 to November 2023. Patients were divided into two groups based on the desensitization strategy they received: the anti-CD20 monoclonal antibody combined with therapeutic plasma exchange (TPE) group (n=50) and the anti-CD20 monoclonal antibody combined with Protein A immunoabsorption group (n=32). The differences of efficacy between the desensitization strategies were analyzed. The safety of both desensitization strategies were assessed by close monitoring of adverse events throughout the treatment. The nursing characteristics and interventions specific to these strategies were comprehensively summarized. Results: There were no significant differences in age, gender, and diagnosis between the two groups of patients receiving different desensitization strategies (P>0.05). Following desensitization in the immunoadsorption group, the mean fluorescence intensity (MFI) levels of anti-HLA Class I antibody decreased significantly compared to initial screening (P=0.048), while the decrease in MFI values of anti-HLA Class II antibody was not statistically significant (P=0.173). In the TPE group, the MFI levels for both anti-HLA Class I and II antibodies after desensitization decreased significantly compared to initial screening (P=0.025 and 0.028, respectively). Monitoring of adverse events during desensitization treatment, found that patients in the immunoadsorption group experienced mild decreases in blood pressure during the process, with two patients developing severe hypotension. No allergic reactions occurred, and no damage of liver or kidney function was observed after the immunoadsorption. In the immunoadsorption group, a total of 19 patients underwent sera immunoglobulin assays before and after immunoadsorption. Compared to the initial screening, the immunoglobulin G (IgG) levels significantly decreased after immunoadsorption (P<0.001). In TPE group, 12 patients experienced mild hypotension during the plasma exchange process, but no severe hypotension was observed. One patient developed an allergic reaction. After the TPE treatment, no damage of liver or kidney function was observed, nor any decrease of IgG levels. In terms of safety of intravenous access, neither group experienced severe complications such as catheter-related bloodstream infections or deep vein thrombosis. In the TPE group, catheter occlusion occurred during the process of plasma exchange in 2 patients, while no such incident was observed in the immunoadsorption group. Patients of both groups exhibited anxiety and depression before treatment. After psychological care, the scores for anxiety and depression significantly decreased (P<0.001). Conclusion: Both desensitization strategies significantly decreased the HLA antibodies in highly sensitized patients with high level of HLA antibodies undergoing allo-HSCT. For patients receiving immunoabsorption, nursing care should focus on preventing and managing hypotension and implementing infection-prevention measures due to IgG depletion. In contrast, for those undergoing TPE, vigilant monitoring and prompt management of potential allergic reactions are essential components of nursing practice.

Objective:To explore the clinical and genetic characteristics of dyskeratosis congenita (DC).Methods:A retrospective analysis was conducted on the clinical, laboratory, imaging, pathological, genetic, and treatment data of 6 DC patients diagnosed at the Children′s Hospital of Zhejiang University School of Medicine from January 2010 to June 2025.Results:Among the 6 DC patients, 1 case was of Hoyeraal-Hreidarsson syndrome, 4 were male, and 2 were female. The diagnosis age 0.9-6.1 years. All 6 cases presented with bone marrow failure; 5 cases had a classic triad of skin and mucous membrane (mucosal leukoplakia, abnormal skin pigmentation, nail dystrophy); 5 cases had growth retardation, among which 2 cases had intrauterine growth retardation. Two cases had diarrhea and 1 case had abnormal liver function; 1 case had stiff and deformed limbs, accompanied by limited mobility, and dry and obstructive balanitis; 1 case had recurrent eyelid inflammation, middle ear inflammation, and nasal inflammation. All 6 cases had decreased B cell numbers, and 4 cases also had decreased natural killer cell numbers. There were 3 cases of children with cytomegalovirus (CMV) infection, of which 1 case of CMV infection led to retinal frosted branch angiitis and subsequent intracranial CMV infection resulting in death, and 1 case had CMV enteritis and died of hemophagocytic syndrome. Among 4 cases of boys, 3 cases had DKC1 gene variations and 1 case had an unknown variation gene; 2 cases of girls had TINF2 gene variations. The TINF2 c.860T>A (p.L287Q) variation site was a new mutation. Among 6 patients with DC, 2 cases died, 3 cases survived and 1 case was lost to follow-up.Conclusions:The DKC1 and TINF2 genes are common pathogenic genes in patients with DC. Bone marrow failure is a clue for the early identification of DC. The triad of skin and mucous membrane is its typical clinical manifestation. Children with DC generally have reduced B cells and natural killer killer cells, and have a high risk of fatal CMV infection. The overall prognosis is poor.

Fetal sacrococcygeal teratoma(SCT)is a rare condition,but the prognosis of fetuses diagnosed with SCT prenatally is generally poor,with a mortality rate of 13% to 50%. The primary causes of death include fetal hydrops and high?output heart failure,while other causes include tumor rupture,hemorrhage,preterm labor,dystocia,or malignant teratoma invasion of surrounding tissues. For large tumors,especially those with rich blood supply or rapid growth,intrauterine treatment should be considered to prevent arteriovenous shunting,reduce tumor size,and reverse fetal heart failure and hydrops. This approach aims to allow the fetus to grow safely to a viable gestational age,after which the tumor can be completely removed by secondary surgery following cesarean delivery or natural childbirth. Currently,there are five main intrauterine treatment strategies:①Ultrasound?guided cystic teratoma aspiration:single or multiple aspirations,intrauterine continuous drainage,or prenatal aspiration;②Ultrasound?guided alcohol sclerotherapy;③Open fetal surgery;④Laser ablation:fetoscopic?guided ablation of feeding vessels of the teratoma,or ultrasound?guided laser ablation;⑤ Ultrasound?guided radiofrequency ablation(RFA).According to the literature,the latter two minimally invasive intrauterine treatment methods show better outcomes for teratomas containing solid components and are gradually becoming the mainstream treatment options.

To study the prevalence of depression, anxiety, and insomnia among social workers during the prolonged battle against the COVID-19 pandemic and explore the associated risk factors. Using a stratified cluster sampling method, we selected all social workers in the five streets of Chaoyang District, Beijing(Jiuxianqiao, Wangjing, Taiyanggong, Shibalidian, Sunhe) from November 2021 to March 2022 as the study population(social worker group), and the frontline medical staffs(medical professional group) of the same age range of the corresponding community hospitals of the same five streets, and the community residents(resident group) as the control population. The ratio of the social worker group, medical professional group, and resident group was 1∶1∶1. The Sojump platform was used to send electronic questionnaires to the wechat groups of social workers, healthcare workers, and community residents to carry out the survey. The screen positive rates for anxiety, depression, and sleep disorders were compared among the 3 groups. Multifactorial Logistic regression and decision tree were used to analyze the influencing factors of anxiety, depression, and sleep disorders among social workers. A total of 954 questionnaires were collected, of which 62 were disqualified and excluded. Finally, 892 valid questionnaires(93.5%) were included for data analysis. Among them, there were 372 questionnaires(41.7%) from the social worker group, 262(29.4%) from the medical professional group, and 258(28.9%) from the resident group. The prevalences of anxiety, depression, and sleep disorders among social workers group were found to be 15.3%, 22.0%, and 48.1%, respectively, which were significantly higher than those in the medical professional group(7.6%, 10.3%, and 30.5%) and the resident group(7.0%, 8.5%, and 29.5%), all Social workers exhibited significant levels of anxiety, depression, and sleep disorders during the long-term pandemic prevention, with CPSS being the most significant influencing factor.

Cryptogenic multifocal ulcerous stenosing enteritis(CMUSE) is a rare and difficult disease characte-rized by chronic recurrent intestinal obstruction and gastrointestinal bleeding caused by multiple ulcers and strictures of the small intestine. There is still a lack of mature and systematic guidance for the treatment of the disease. This paper reported a case of CMUSE mainly manifested as fatigue, abdominal distention, and edema of both lower limbs , who is treated by integrated traditional Chinese and western medicine. In western medicine treatment, hormone and symptomatic treatment are mainly used. In traditional Chinese medicine treatment, the method of fortifying spleen and reinforcing healthy qi is taken as the basis; during the active stage of the disease, the method of moving qi and removing stagnation, clearing and removing dampness and heat, astringing and engendering flesh should be combined with, while during the remission stage, it is advised to unite with the method of diffusing lung and moving water, regulating and harmonizing zang-fu (脏腑) organs; simultaneously, replenishing qi and invigorating blood can be used throughout the treatment, and attach importance to the maintenance therapy of the traditional Chinese medicine immunomo-dulatory agent Tripterygium glycosides. After more than 2 years of treatment, the patient's clinical symptoms were significantly relieved, and all indicators basically restored to normal, having a stable condition.
