ABSTRACT
ABSTRACT Objective: Based on the evaluation method with fuzzy integrals, this paper analyzes the results of physical health tests of college students. Methods: Principal component analysis was used to extract the psychological factors. The evaluation model was organized into three levels to evaluate the physical health of college students. Results: The physical health status of University Q students is below average. Most of the students' physical examination results are concentrated in the passing areas, and few students have an excellent to good ratio. Conclusion: The fitness assessment model of university students, based on an assessment with fuzzy integrals, has certain generalizability and applicability. The established index system and the comprehensive evaluation model are suitable for thoroughly evaluating each student and comprehensive fitness evaluation of all boys and girls in a class or college. Level of evidence II; Therapeutic studies - investigation of treatment results.
RESUMO Objetivo: Com base no método de avaliação com integrais fuzzy, este documento analisa os resultados dos testes de saúde física dos estudantes universitários. Métodos: Foi utilizada a análise de componentes principais para extrair os fatores psicológicos. O modelo de avaliação foi organizado em três níveis para avaliar a saúde física dos estudantes universitários. Resultados: O estado de saúde física dos estudantes da Universidade Q está abaixo da média. A maioria dos resultados dos exames físicos dos estudantes está concentrada nas áreas de aprovação, e poucos estudantes têm uma proporção excelente e boa. Conclusão: O modelo de avaliação da aptidão física dos estudantes universitários, baseado em uma avaliação com integrais fuzzy, tem certa generalização e aplicabilidade. O sistema de índice estabelecido e o modelo de avaliação abrangente não só são adequados para avaliação abrangente de cada estudante, mas também para avaliação abrangente da aptidão física de todos os meninos e meninas de uma classe ou faculdade. Nível de evidência II; Estudos terapêuticos - investigação de resultados de tratamento.

La mayoría de los resultados de los exámenes físicos de los estudiantes se concentran en las zonas de aprobado, y son pocos los que tienen una proporción excelente y buena. Conclusión: El modelo de evaluación de la aptitud física de los estudiantes universitarios basado en una evaluación con integrales difusas tiene cierta generalizabilidad y aplicabilidad. El sistema de índices establecido y el modelo de evaluación integral no sólo son adecuados para la evaluación integral de cada estudiante, sino también para la evaluación integral de la aptitud de todos los chicos y chicas de una clase o colegio.

ABSTRACT
The incidence rate of lower limb fractures is high and has increased over the recent years, which affects the physical and mental health and the daily activities of patients. Lower limb fractures are often treated surgically. Therefore, an effective anesthesia regimen is crucial for a smooth and stable operation. To investigate the efficacy of posterior lumbar plexus block anesthesia during surgery for elderly patients with lower extremity fractures. In total, patients were divided into study and control groups. Anesthesia was administered by posterior lumbar plexus nerve block in the study group and epidural anesthesia in the control group. Hemodynamic parameters, anesthesia condition, pain level (VAS), and adverse effects were measured in both groups before anesthesia (T0), at anesthesia induction (T1), 30 min into the operation (T2), and at the end of the operation (T3). At T0, there were no significant differences in MAP and HR between the study and control groups. However, MAP and HR in the study group were significantly lower than those in the control group at T1, T2, and T3. The BIS value of the study group at each time point after anesthesia was significantly lower than that of the control group. The onset and induction time of anesthesia in the study group were also significantly shorter than those in the control group. Preoperative VAS scores did not differ between the study and control groups. However, the VAS scores of the study group at each time point were significantly lower than those of the control group. There was no significant difference in the incidence of adverse reactions between the two groups. Our results suggest that anesthesia with posterior lumbar plexus block surgery for lower extremity fractures in elderly patients can maintain hemodynamic stability and reduce block onset time, anesthesia induction time, and pain.
