Methods Patients with clinically suspected endometrial cancer were prospectively enrolled and underwent MRI before the operation,which mainly included APTw and T2 mapping.Two radiologists independently performed regions of interest and measured the quantitative parameters.The intraclass correlation coefficients were used to assess the interobserver agreement,the independent samples t-test and Mann-Whitney U test were applied to compare quantitative variables between the MSI and microsatellite stable(MSS)groups,the receiver operator characteristic(ROC)curve was conducted to evaluate the predictive performances of different parameters,the Delong test was implemented to compare the area under the curve(AUC)between single parameters and their combination. Results Twenty-one patients in the MSI group and 37 patients in the MSS group were finally enrolled in this study.The results showed excellent observer agreements between two observers in assessing MRI parameters.APTw values[(2.72±0.52)% vs.(2.08±0.39)%,P<0.001]in the MSI group were significantly higher than those in the MSS group, T2 values [92.25(90.82, 99.91) ms vs.101.80(96.15, 112.13)ms, P<0.001]were significantly lower in the MSI group than those in the MSS group.The ROC curves showed that the AUCs of APTw and T2 values were 0.821 and 0.793,respectively,and no significant difference was observed between the two sequences(P＞0.05).The combination of APTw and T2 mapping yielded the highest AUC of 0.897,which was significantly higher than APTw and T2 mapping alone(both P＜0.05).

This study examines tissue-specific bioaccumulation and antioxidant responses in <em>Procambarus clarkii</em> following exposure to environmentally relevant Gd concentrations (0.1, 1, 10, and 100 μg/L) over 14 days. Bioaccumulation was evident in the gills and hepatopancreas at higher exposure levels (10 and 100 μg/L), whereas muscle concentrations remained below the limit of quantification. Oxidative stress responses varied by tissue, with no clear trend revealed by the non-metric multidimensional scaling (NMDs), suggesting limited antioxidant activation likely due to low Gd accumulation and short exposure duration. However, superoxide dismutase (SOD) activity significantly increased in the gills and hepatopancreas at higher Gd concentrations. In contrast, glutathione peroxidase (GPx) activity showed inconsistent trends, while glutathione S-transferase (GST) activity was elevated in hepatppancreas and muscle only at 0.1 μg/L. Lipid peroxidation was most pronounced in the gills. The Integrative Biomarker Response-Threshold (IBR-T) index revealed low-dose effects consistent with hormetic responses, highlighting biologically relevant alterations observed at the lowest Gd concentrations. These findings suggest that <em>P. clarkii</em> exhibits tissue-specific Gd bioaccumulation and oxidative stress responses, albeit with variable biomarker activation.

To solve this problem, a vehicle dispatching plan selecting method based on fault-tolerance analysis is proposed, which considers the bounded rationality of emergency decision-makers. The method improves the capability of responding to unexpected scenarios by increasing backup resources. First, under the expected scenarios, a bi-level programming model for arranging the quantities of each type of vehicle and their routes is established, with the goal of minimizing the expected total evacuation time. A corresponding solving algorithm is designed. Second, possible unexpected scenarios are preset by integrating local and non-local historical experiences, and the scenario influences on vehicle dispatching constraints are analyzed. Third, under unexpected scenarios, a fault-tolerance plan set is established considering the failure risk of vehicle dispatching and fault-tolerant cost. The optimal plan is selected by calculating and ranking fault-tolerant rates. Finally, a case study in Shenzhen, China is provided to verify the reasonability and effectiveness of the method. The results show that the proposed method can help discover and address the ‘fault’ of vehicle dispatching plans during emergency preparedness and thus improve evacuation capabilities in emergency response.

By utilizing data from a wastewater plant in Shenyang City and referring to the IPCC 2006 Guidelines for National Greenhouse Gas Inventories 2019 Revision and the Technical Guidelines for Carbon Accounting and Emission Reduction Pathways in Urban Water Systems， this study accounts for the carbon emissions from three segments： wastewater conveyance， wastewater treatment， and sludge disposal. Additionally， it analyzes the influencing factors of carbon emissions at this particular plant， which will aid in implementing region-specific measures to reduce carbon emissions. The results showed that the annual carbon emission of a wastewater treatment plant in Shenyang City was 52 450 t. The main factors contributing to this emission were power consumption （39.2%）， the use of polymeric aluminum chloride （18.7%）， and N₂O emissions caused by the wastewater treatment （14.5%）. By using Sumo software package to analyze the key parameters for reducing carbon emissions in the wastewater treatment plant， it was concluded that dissolved oxygen levels could be reduced from the original 6.51 mg·L^-1 to 1-2 mg·L^-1. Additionally， by reducing the dosage of polymeric aluminum chloride to 76% of its original amount， it was possible to reduce the water plant's carbon emissions by 2 230 t. The annual consumption of sodium acetate could be reduced from 3 710 t to 2 672 t， and the carbon emissions were reduced by 28.14% compared to the original levels. Based on the carbon emission accounting results of the plant， the following feasible paths for emission reduction were proposed： optimizing aeration equipment and pumping units to reduce power consumption； introducing precise dosing equipment to minimize pharmaceutical usage； reducing stockpiling time for residual sludge in the plant； employing appropriate methods for recovering phosphorus， macromolecules， and other resources from wastewater and sludge； and utilizing water source heat pump technology for exchanging heat energy in wastewater treatment plant effluent.
