Objective: To investigate the clinical effect of ω-3 polyunsaturated fatty acids (ω-3 PUFA) on elder patients after gastric cancer radical operation. Methods: Forty patients were randomly divided into experimental group (EG) and control group(CG). The patients of CG were treated with hypocaloric and lower nitrogen parenteral nutrition, and those in EG received ω-3 PUFA additionally. The nutrition index, immune function, liver function, inflammatory reaction and complications were compared. Results: The rate of complications significantly decreased in the EG (20% vs 5% , χ~2 = 3. 958, P < 0. 05). There were no significant differences in albumn and hemoglobin between the two groups (P > 0. 05). The level of prealbumin was significantly increased in the EG. The humoral immunity and cellular immunity were higher in the EG than those in the CG. IL-6, TNF-α and CRP levels on postoperative d5 were significantly depressed in the EG. Conclusion: Postoperative supplementation of ω-3 PUFA may have a favorable effect on the outcomes in elder gastric cancer patients.

ObjectiveTo explore the influencing factors of anticipatory grief among family caregivers of terminal-stage cancer patients，and provide a reference for formulating intervention programs for anticipatory grief. MethodsAn interview outline was designed，and the descriptive qualitative research method was used.The aim was to select 11 family narrative caregivers of patients in the Department of Medical Oncology，Nanfang Hospital，Southern Medical University for semi-structured in-depth interviews.Based on the social ecology model，using the narrative theory of life and health as the framework，the content analysis method was adopted to analyze the data. ResultsA total of 3 themes and 12 sub-themes were extracted，including the influencing factors at the individual level （narrative literacy，cognitive level towards death，and sense of self-worth），the influencing factors at the interpersonal level （patient’s disease situation，education level，economic status，family narrative connection，peer narrative connection，and narrative connection between doctors and family members），and the influencing factors at the cultural policy level （social culture，physical environment of the ward，and policy level）. ConclusionAnticipatory grief was affected by multiple factors，and multi-dimensional narrative connection should be constructed from individual，interpersonal，family，social，and other levels to prevent caregivers from falling into a narrative lock of single caregiver identity，alleviate the impact of anticipatory grief on caregivers，and improve their quality of life.

Objective:To construct an anticipatory grief intervention scheme for family caregivers of advanced cancer patients based on narrative theory, and to provide reference for anticipatory grief nursing intervention.Methods:From October 2022 to May 2023, through literature research, semi-structured interview and brainstorming method, the first draft of nursing intervention plan was constructed, the Delphi method was used to conduct 2 rounds of correspondence consultation with 15 experts, and the indicators at all levels were modified according to the opinions of experts, and the final draft of intervention plan was formed.Results:The experts were all female, aged (49.67 ± 5.83) years old. The authority coefficient of the two rounds of experts was 0.87. The Kendall coordination coefficients of the first, second, and third level indicators after the first round of expert inquiry were 0.195, 0.113, and 0.093, respectively. The Kendall coordination coefficients of the first, second, and third level indicators after the second round of expert inquiry were 0.200, 0.119, and 0.101, respectively. The differences were statistically significant ( χ2 values were 8.76-107.21, all P<0.05).Finally, a nursing intervention plan based on narrative theory was formed, which included 4 primary indicators, 19 secondary indicators and 72 tertiary indicators. Conclusions:The anticipatory grief intervention scheme for family caregivers of advanced cancer patients is scientific, practical and feasible, and can be used for psychological nursing of family caregivers.
