Objective : To analyze the distribution characteristics of free water ( FW) and FW-corrected fractional anisotropy (FAt) in the white matter of the brain in patients with anti-N-methyl-D-aspartate receptor ( NMDAR) encephalitis and to explore their correlation with cognitive function． Methods : A total of 38 patients with anti- NMDAR encephalitis and 30 controls were recruited from three hospitals in Hefei．Diffusion tensor imaging data and neuropsychological assessment results were collected．Tract-Based Spatial Statistics was applied to compare group differences in FW and FAt across the whole brain white matter．Correlation analyses were further performed to ex- amine the relationships between FW/ FAt metrics and cognitive function． Results : Compared to the control group， patients with anti-NMDAR encephalitis showed significantly lower scores on the montreal cognitive assessment，im- mediate recall，delayed recall，and the verbal fluency test (all P＜0. 05) ，as well as significantly longer comple- tion times for color naming and word reading tasks in the stroop color word test (all P＜0. 05) ．Diffusion tensor im- aging analysis revealed significantly elevated FW and reduced FAt in widespread white matter regions in the patient group (all P＜0. 000 1) ．Further correlation analysis showed that increased FW was positively associated with the completion time of the color-switching condition in the color digital trail making test (P = 0. 044 ) and with the difference between color-switching and number sequencing conditions ( P = 0. 016 ) ，while negatively correlated with semantic fluency scores (P = 0. 002) ．Additionally，FAt was positively associated with delayed recall perform- ance (P = 0. 012) ，and negatively correlated with the completion times for color naming (P = 0. 018 ) and word reading (P = 0. 046) tasks in the SCWT． Conclusion Patients with anti-NMDAR encephalitis exhibit significantly elevated FW and significantly reduced FAt in white matter tracts，both of which are closely linked to cognitive im- pairment．

Objective: To investigate the inhibitory effect of Elesclomol (ES) + Cu2 + on the proliferation of human hepatoma cell lines PLC/PRF/5 and Huh-7 and its potential to induce Cuproptosis. Methods: Human hepatoma cell lines PLC/PRF/5 and Huh_7 cells were Cultured in vitro. ES solution , Cu2 + solution and copper chelating agent ammonium tetrathiomolybdate VI (ATTM) solution was treated separately or in combination. The effect of ES + Cu2 + on the survival rate of human hepatoma cell lines PLC/PRF/5 and Huh_7 cells and the effect of ES + Cu2 + on the survival rate after pretreatment with copper chelating agent ATTM were evaluated using CCK_8 kit. The cell death induced by ES + Cu2 + was detected by flow cytometry and the changes of ES + Cu2 + after pretreatment with copper chelating agent ATTM. The expression of Cuproptosis related proteins ATPase copper transporting beta (ATP7B) ,ferredoxin 1 (FDX1) , dihydrolipoamide s_acetyltransferase(DLAT) and superoxide dismutase 1 (SOD1) were detected by Western blot. The effect of ES + Cu2 + on cell proliferation and the reverse effect after ATTM pretreatment was detected by cell scratch assay. Results: The toxicity of ES + Cu2 + to human hepatocellular carcinoma cell lines PLC/PRF/5 and Huh_7 was significantly dose_dependent (P < 0. 05) . Compared with the control group , the combined application of ES and Cu2 + had a more significant inhibitory effect on hepatocellular carcinoma cells than ES or Cu2 + alone (P < 0. 05) , and copper chelating agent ATTM could reverse the inhibitory effect of ES + Cu2 + on hepatocellular carcinoma cells (P < 0. 05) . Flow cytometry results showed that compared with the control group , the proportion of cell death in PLC/PRF/5 and Huh_7 cells treated with ES + Cu2 + increased , while the proportion of cell death decreased after ATTM intervention (P < 0. 05) . The results of cell scratch test showed that the migration ability of PLC/PRF/5 and Huh_7 cells was decreased after ES + Cu2 + treatment , however, the addition of ATTM reversed the inhibitory effect of ES + Cu2 + on cell migration (P < 0. 05) . Compared with the control group , the expression levels of copper death related proteins ATP7B , FDX1 , DLAT and SOD1 decreased after ES + Cu2 + treatment , but the addition of ATTM reversed the expression trend of these proteins (P < 0. 05) . Conclusion The combination of ES and Cu2 + can effectively inhibit the proliferation and migration of PLC/PRF/5 and Huh_7 of hepatocellular carcinoma cells , and induce Cuproptosis , which provides a new strategy for the treatment of hepatocellular carcinoma.

Lung cancer is a major cause of cancer-related mortality worldwide. Among patients with non-small cell lung cancer (NSCLC), approximately 3%-7% harbor anaplastic lymphoma kinase (ALK) gene fusions. In recent years, multiple tyrosine kinase inhibitors (TKIs) have significantly improved the survival of patients with metastatic ALK-positive NSCLC. However, disease progression due to resistance remains a challenge. This article retrospectively analyzes a case of advanced lung adenocarcinoma with the echinoderm microtubule associated protein like 4 (EML4)-ALK fusion variant 3 (V3). The patient developed resistance to Lorlatinib treatment accompanied by mesenchymal-epithelial transition factor (MET) amplification. Effective tumor control was achieved with the combined use of Crizotinib and Lorlatinib, providing a valuable reference for further exploration of treatment strategies following resistance to ALK-TKIs in clinical practice.

Objective To explore the effectiveness of Failure Modes and Effects Analysis(FMEA)in emergency man-agement of sudden incidents involving outpatient and emergency patients in general hospitals,to provide references for the optimi-zation of emergency response process for such incidents.Methods Based on FMEA,we identified and evaluated risks in the e-mergency response procedures for sudden incidents involving outpatient and emergency patients in general hospitals.Potential fail-ure modes were analyzed to identify key risks with a Risk Priority Number(RPN)greater than 125.Continuous quality improve-ment measures were implemented to control these risks,and the effectiveness of these controls was evaluated using chi-square tests for statistical analysis.Results A total of 16 risk points in 4 major areas were identified.After implementing continuous quality improvement measures,the RPNs of these high-risk points decreased to below 125,effectively controlling the potential risks.This intervention significantly improved the utilization rate of emergency equipment,the timely reporting rate of sudden in-cidents,the timely feedback rate of emergency response,with statistically significant differences(P＜0.01).Conclusion The application of FMEA to outpatient and emergency management of sudden incidents helps optimize the emergency response process,thus enhancing the emergency response capability of general hospitals and ensuring effective handling of such incidents.

Breast cancer, the most common malignancy in the world, also causes the most death cases of women among malignancies. Breast cancer risk reduction guidelines (version 2023) was updated by National Comprehensive Cancer Network (NCCN). Based on high-level evidences from evidence-based medicine and the latest research progress, the guidelines provided standardized guidance for breast cancer risk assessment and risk reduction strategies for individuals without a history of invasive breast cancer or ductal carcinoma in situ, which has attracted widespread attention from clinicians worldwide. Breast cancer is also the most common malignancy in Chinese women, and the number of newly diagnosed breast cancer cases each year in China ranks first in the world due to the large population, so the breast cancer prevention has become a major public health challenge in China. Aimed to provide reference for breast cancer prevention in China, this article interpreted the guidelines (the new version) based on the characteristics of breast structure in Asian women and the epidemiological characteristics of breast cancer in China.
