Objective:To investigate the effect of armadillo repeat containing X-linked 3(ARMCX3)on the proliferation,migration,and invasion of breast cancer cells and its potential molecular mechanism.Methods:Immunohistochemistry was used to measure the expression of ARMCX3 in breast cancer tissue and adjacent tissue,and Western blot was used to measure the expression of ARMCX3 in breast cancer cells.Breast cancer cells were transfected with lentivirus to establish a model of breast cancer cells with low expres-sion of ARMCX3,and flow cytometry,colony formation assay,scratch assay,and Transwell assay were used to observe the effect of ARMCX3 on the proliferation,migration,and invasion of breast cancer cells.TCGA and GTEx databases were used to analyze the ex-pression of SRY-box transcription factor 9(SOX9)in breast cancer tissue,and GEO database was used to analyze the correlation be-tween SOX9 and ARMCX3.Western blot was used to measure the expression levels of E-cadherin,N-cadherin,vimentin,and SOX9 in breast cancer cells.Results:Compared with adjacent tissue and human normal breast epithelial cells,there was a significant in-crease in the expression level of ARMCX3 in breast cancer tissue and most breast cancer cell lines(P<0.05).Compared with the con-trol group,the low expression of ARMCX3 inhibited the prolifera-tion,migration,and invasion of MCF-7 and MDA-MB-231 cells,promoted the expression of E-cadherin,and inhibited the expres-sion of N-cadherin and vimentin(P<0.05).Compared with the nor-mal tissue,there was a significant increase in the expression level of SOX9 in breast cancer tissue(P<0.001),which was correlated with ARMCX3,and the low expression of ARMCX3 also significantly in-hibited the expression of SOX9.Conclusion:ARMCX3 is highly ex-pressed in breast cancer tissue and breast cancer cells,and it may regulate the proliferation,migration,and invasion of breast cancer cells through SOX9.

To summarize the nursing management experience of 9 patients with lung transplantation undergoing extracorporeal membrane oxygenation(ECMO)combined with continuous renal replacement therapy(CRRT)during perioperative period.The key points of nursing include forming a professional team to ensure the whole process management;comprehensive evaluation and pretreatment of adverse events during the operation to maintain the safe operation of the equipment;refined volume management based on the surgical process ensures intraoperative hemodynamic stability;optimization of intraoperative anticoagulation management to reduce the incidence of complications;multi-device safe transport management ensures the continuity of postoperative treatment.Through comprehensive and targeted nursing intervention,9 patients were successfully treated with ECMO combined with CRRT during the operation.The patients were transferred out of ICU 3～12 days after the operation,and were followed up for 3 months.The patient's condition is good.

The endometrial thickness is a crucial indicator for pregnancy success. Thin endometrium is typically related to low clinical pregnancy and live birth rate. Current research indicates that granulocyte colony-stimulating factor (G-CSF) is a glycoprotein that recognized as a cytokine and growth factor, which may support the establishment of endometrial receptivity during embryo implantation through promoting angiogenesis, embryo adhesion, and trophoblast invasion, thus increasing the endometrial thickness and clinical pregnancy rate. However, there are still conflicts about the efficacy of G-CSF. Therefore, identifying the pathological mechanism of thin endometrium and how G-CSF promotes endometrial thickness and receptivity has clinical significance. This article will review the progress on clinical research and molecular mechanism of G-CSF in treating thin endometrium.

With the rapid development of artificial intelligence (AI) technology, its application in embryo evaluation is becoming more and more extensive. This article reviews the main progress of AI in embryo evaluation in recent years, including image recognition, embryo quality evaluation and outcome prediction. AI models can effectively analyze large-scale embryo image data and identify morphological features, thereby improving the accuracy and efficiency of evaluation. In addition, AI can also integrate images and clinical data to provide individualized embryo evaluation strategies. While AI shows promising potential in embryo evaluation, challenges remain in model interpretability and clinical application standardization. Future study needs to explore the application potential of AI in embryo evaluation in depth to promote the development and innovation of reproductive medicine.

Objective To investigate the current status,evolving hotspots,and emerging trends in the field of human re-source allocation research in public hospitals,both domestically and internationally,to provide a reference for future research di-rections in China.Methods CiteSpace was used to conduct a visual analysis of the research literature on human resource alloca-tion in public hospitals based on China National Knowledge Infrastructure(CNKI)and the Web of Science(WOS).The analysis encompassed co-authorship,institutional collaboration,keyword co-occurrence and clustering,and burst detection.Results A total of 1 417 Chinese articles and 981 international articles were included.Domestic research in this field focused more on healthcare reform and management,resource allocation,hierarchical diagnosis,and treatment,and informatization and efficiency improvement.On the contrary,international research primarily centered on the employee satisfaction,healthcare system quality,work environment and medical staff.Future trends in domestic research included cost reduction,efficiency enhancement,and a greater emphasis on public welfare in public hospitals,while international research was beginning to explore the influence of polit-ical concepts in this field.Conclusion Compared to international research,domestic research needs to further improve its theo-retical and localized understanding,broaden its research scope,explore the interdisciplinary collaboration opportunities,and delve into research directions such as the application of artificial intelligence and automation technology in healthcare services,management of a diverse workforce,and innovative management techniques and applications.

Objective:To study the localization value of stereoelectroencephalography (SEEG) in refractory epilepsy associated with tuberous sclerosis complex (TSC), and to analyze the prognosis related factors.Methods:A case control study.Data of 66 patients with TSC-related refractory epilepsy who underwent SEEG placement at the Epilepsy Center of Tsinghua University Yu-Quan Hospital from January 2014 to March 2023 were retrospectively analyzed, including medical history, seizure semiology, scalp electroencephalogram (EEG), imaging, and SEEG findings.Patients were divided into a seizure-free group and a seizure group according to the seizures after surgery. t/ χ2 test was used to compare the relationship between age of onset, age of surgery, duration of epilepsy, genetic findings, seizure symptoms, scalp EEG characteristics, SEEG placement protocol and prognosis. Results:A total of 66 patients met the enrollment criteria, of whom 55 patients were seizure-free after surgery (seizure-free group), and 11 patients still had seizures (seizure group).Among the 66 patients, there were 46 males and 20 females; the age of onset was (21.72±30.01) months; the age of SEEG surgery was (6.79±5.12) years; the duration of epilepsy was (4.98±4.11) years.SEEG results showed that seizures started with a single tuber in 43 patients (64.4%), seizures started with 2 or more tubers in one hemisphere in 16 patients, and 7 patients had bilateral multi-tubers or the pathogenic tuber(s) could not be identified.The following factors were found to be associated with prognosis: early age of surgery ( t=-3.463, P<0.01), ictal scalp EEG with a definite lateralization ( χ2=7.876, P<0.05), and the concordance of interictal and ictal EEG ( χ2=6.821, P<0.05).The age of onset, duration of epilepsy, seizure type and symptom, genetic findings, and SEEG placement protocol were not significantly correlated with prognosis.The results of SEEG identified that onset with a single tuber revealed a better postoperative outcome. Conclusions:This study confirms the safety and efficacy of SEEG in TSC-related refractory epilepsy, and also finds that ictal EEG is uniquely valuable in guiding SEEG placement for TSC-related refractory epilepsy, which can help us better select patients with TSC-related refractory epilepsy who are suitable for SEEG placement.
