Objective:To explore different types of psychological reactions of spouses of young and middle-aged breast cancer patients and their influencing factors based on potential profile analysis, so as to provide reference for targeted intervention in clinical practice.Methods:A cross-sectional investigation method was used to select the spouses of middle-aged and young patients with breast cancer who were hospitalized in the Second Affiliated Hospital of Guilin Medical University, Quanzhou County People's Hospital, and Bobai County People's Hospital from January 2023 to June 2024. General Data Questionnaire, Spousal Psychological Response Scale of Breast Cancer Patients, Perceived Partner Responsiveness Scale and Perceptive Social Support Scale were used to investigate. The potential profile analysis of spousal psychological reaction of young and middle-aged breast cancer patients was carried out, and the influencing factors of different categories were analyzed by ordered multiple Logistic regression.Results:A total of 232 questionnaires were distributed, and 211 valid questionnaires were collected, with an effective response rate of 91.0%.The spouses of 211 middle-aged and young patients with breast cancer were 30-59 (43.25 ± 2.58) years old. The total psychological response score was (69.96 ± 8.36). The low psychological response high coping group accounted for 24.6% (52/211), the moderate psychological response group accounted for 33.2% (70/211), and the high psychological response low coping group accounted for 42.2% (89/211). The results of ordered multiple Logistic regression analysis showed that cumulative care time, tumor stage of patients, perceived partner responsiveness, and perceived social support were the influencing factors of potential categories of psychological responses of spouses of young and middle-aged breast cancer patients ( OR values were 0.014-0.304, all P<0.05). Conclusions:There is heterogeneity in the psychological reactions of spouses of young and middle-aged breast cancer patients. According to the characteristics of the classification, the nursing staff should formulate targeted intervention strategies, focusing on improving the perceived partner responsiveness, establishing an effective social support system, and reducing the level of psychological response.

Objective:To investigate the relationship between NOD-like receptor protein 3 (NLRP3) gene promoter region-30 single nucleotide polymorphism (SNP) (rs3738448) G/T and dilated cardiomyopathy (DCM) and its related risk factors.Methods:A case-control study method was used to collect 137 patients and 140 healthy controls; polymerase chain reaction-restriction endonuclease fragment length polymorphism technology combined with sequence alignment after DNA sequencing was used for data statistics; After Hardy-Weinberg balance test, the χ 2 test was used for correlation analysis; logistic regression was used to analyze the correlation between multiple risk factors and the SNP site and the incidence of DCM; SNPinfo database was used to predict and analyze the transcription factors affected by the SNP. Results:A total of GG and GT genotypes were detected at this SNP locus, and their genotype distributions were in line with Hardy-Weinberg equilibrium ( P>0.05). At the same time, the difference between the DCM group and the control group was significant ( P<0.05). Multivariate logistic regression analysis indicated that mean arterial pressure, C-reactive protein and B-type brain natriuretic peptide were independent risk factors for the onset of DCM (all P<0.05). The incidence of DCM in -30(RS3738448)G/T genotype GT group was 2.243 times higher than that in GG group (95% CI: 1.043-4.827, P<0.05). Logistic regression analysis under dominant, recessive and additive genetic models showed that there was a correlation between the dominant inheritance of SNP and the occurrence of DCM ( OR=0.44, AIC=370.4, BIC=381.3, P<0.05). Conclusions:The -30 (rs3738448) G/T SNP in the promoter region of the NLRP3 gene is associated with the pathogenesis of DCM, and provides population genetic data for the study of polymorphisms in the promoter region of NLRP3 gene.

Objective:To establish a simplified anatomical model with the selected rabbits widely distributed in China′s dry region as the reference species and compare the result of internal exposure dose coefficients based on the present mode and ERICA.Methods:A simplified anatomical model based on anatomy and geometry was established for rabbits. Combined with Monte Carlo program, the deposited energy of radionuclide particles in rabbit tissues/organs was obtained, and the internal and external exposure dose coefficient for rabbits was calculated following the empirical formula.Results:Simplified anatomy model-based dose coefficients were 129I 4.81 × 10 -6, 137Cs 4.34 × 10 -5, and 134Cs 3.81 × 10 -5(μGy·h -1)/(Bq·kg -1) for internal exposure and 129I 3.16 × 10 -7, 137Cs 2.39 × 10 -4 and 134Cs 6.22 × 10 -4(μGy·h -1)/(Bq· kg -1) for external exposure. respectively. ERICA-based dose coefficients were 129I 4.44 × 10 -5, 137Cs 1.94 × 10 -4 and 134Cs 2.34 × 10 -4(μGy·h -1)/(Bq·kg -1) for internal exposure and 129I 2.19 × 10 -6, 137Cs 2.52 × 10 -4 and 134Cs 6.95 × 10 -4(μGy·h -1)/(Bq·kg -1) for external exposure, respectively. Conclusions:The simplified anatomical model established is based on the measured data and focuses on the radiation doses to biological tissues/organs, and the calculated result based on the present model are closer to the actual situation, and can provide reference values for the reference biological evaluation of non-human species.
