Objective To gain insights into the biological characteristics of different populations of Culex tritaeniorhynchus within and around the Yellow Sea wetland from the perspective of the occurrence of resistance, we investigated the levels of resistance to deltamethrin and kdr gene mutation in the wetland and its peripheral areas. Methods Specimens were collected from Cx. tritaeniorhynchus populations at two monitoring sites in the Rare Bird National Nature Reserve and Tiaozi Ni Wetland Scenic Area, and also from two populations in Yancheng City and the Liuhe District of Nanjing, and the resistance of these mosquitoes to deltamethrin was determined using the CDC biotest bottle method. For each concentration of deltamethrin assessed, a random subset of exposed specimens was selected for amplification of the kdr gene fragment, followed by Sanger sequencing to identify and analyze resistance-associated mutations. Results The LC50 levels of deltamethrin among mosquitoes from the four populations in Luhe, Yancheng, the Rare Bird National Nature Reserve and the Tiaozi Ni Wetland Scenic Area were 2.048 5, 7.798 2, 3.473 3, and 17.695 5 mg/mL, respectively, with corresponding concentrations of deltamethrin ranging from 0.005 to 5.000,0.050 to 50.000,0.050 to 25.000 and 0.050 to 50.000 mg/mL, respectively. Furthermore, the ranges of the KT50 values were 11.76-107.43, 67.05-216.30,29.77-107.43 and 28.40-329.51 min; the 1-h knockdown rates were 34.58%-99.15%, 9.52%-43.80%, 55.09%-73.01%, and 10.09%-68.07%; and the 24-h mortality rates were 12.15%-67.52%,9.52%-79.56%,13.17%-82.21%, and 11.01%-78.99%, respectively. With respect to kdr gene mutation, we assayed a total of 63,70,59, and 57 mosquitoes for the four populations, for which we detected L1014F mutation frequencies of 14.29%, 35.00%, 20.34%, and 31.58%, respectively, with a majority of these mutations being heterozygous for resistance. In addition, five adult mosquitoes were identified has having synonymous mutations at site 1011[i. e. , AAT(asparagine)mutation to AAC(asparagine)]. Conclusions Our findings revealed the clear resistance of Cx. tritaeniorhynchus to deltamethrin in the Yancheng region of the Yellow Sea wetland, and the resistance phenotype and kdr frequency of Cx. tritaeniorhynchus in the wetland environment were comparable to those of Cx. tritaeniorhynchus in the wetland environment, thereby indicating that the resistance of different populations of Cx. tritaeniorhynchus was homogeneous under the pressure of different insecticide selection within and around the wetland. However, the underlying mechanisms need to be further studied.

Objective:To develop a culturally adapted Advance Care Planning (ACP) Decision Balance Scale for Family Members of Patients with Advanced Cancer in China, and to test its reliability and validity.Methods:Based on the transtheoretical model-decisional balance framework, the item pool was established through literature analysis, qualitative interviews, and research team discussions. After expert panel meetings and semantic debugging pre-surveys among family members of patients with advanced cancer, item screening was conducted to form the pilot scale. From October to December 2024, the scale was administered to 310 family members of inpatients with advanced cancer in five Class Ⅲ Grade A hospitals in Chongqing. SPSS and AMOS software were used for item analysis and reliability and validity testing, and the final formal scale was developed.Results:The ACP Decision Balance Scale for Family Members of Patients with Advanced Cancer consisted of 2 dimensions, perceived cost of choice and perceived benefit of choice, with a total of 12 items. The Cronbach's α coefficient of the scale was 0.875, the split-half reliability was 0.905, and the test-retest reliability was 0.856. The item-level content validity index ranged from 0.880 to 1.000, and the scale-level content validity index was 0.980. Exploratory factor analysis extracted 2 common factors, with a cumulative variance contribution rate of 65.365%. Confirmatory factor analysis showed χ 2/ df=1.743, and the model fit indices met the requirements. The scale also demonstrated good convergent validity and discriminant validity. Conclusions:The ACP Decision Balance Scale for Family Members of Patients with Advanced Cancer developed in this study demonstrated good reliability and validity. It can be used as a tool to assess the level of ACP decision-making participation of family members of patients with advanced cancer, and to systematically, comprehensively, and effectively evaluate, collect, and analyze their behavioral intentions and barriers regarding ACP decision-making.

Objective:To organize and interpret the hot topics and development trends in the field of military medical education research over the past decade with the assistance of visualization software, and provide direction and reference for further study.Methods:Visualization software was used to retrieve relevant literature published worldwide from 2014 to 2023. A visualization analysis was performed on annual publication volume, authors, institutions, and keyword clustering.Results:The numbers of domestic and foreign articles were 452 and 121, respectively. Domestic research reached a peak in 2014 and increased again in 2019 and 2020. Foreign research remained stable from 2014 to 2018 and increased significantly in 2019 and 2020. There were 28 domestic authors and 5 foreign authors who published more than two papers. Domestic research was primarily led by Naval Medical University (47 papers) and Air Force Medical University (21 papers). Internationally, the United States (10 institutions) and Israel (2 institutions) were at the forefront of research in this field. Keyword cluster and label analysis identified 11 cluster labels for domestic research, revealing research hotspots such as curriculum content reform in military medical universities, ideological and political education, practical training for general military doctors, and the improvement of military-civilian integrated medical service capabilities. Foreign research yielded 10 cluster labels, highlighting research hotspots such as emergency medical simulation training, health care, and psychological therapy intervention. Nine burst keywords were identified in both domestic and foreign literatures, indicating a recent domestic focus on job competency and a foreign emphasis on psychological impacts.Conclusions:Over the past decade, domestic research primarily focused on military medical school education reform and grassroots military medical officer education. In the last three years, the emphasis shifted towards the post competency of military medical staff. In contrast, international research centered on public health emergency medicine and health service management, with a shift in the past three years toward addressing both physiological and psychological issues.
