Objective:To investigate the status of post-traumatic stress disorder (PTSD) and its influencing factors in postoperative breast cancer patients.Methods:A convenience sampling method was used to select 410 postoperative breast cancer patients from the Provincial Hospital of the First Medical University of Shandong between January 2023 and December 2024. The PTSD Checklist-Civilian Version (PCL-C), the Connor-Davidson Resilience Scale (CD-RISC), and the Simple Coping Style Questionnaire (SCSQ) were used for assessment. Binary Logistic regression analysis was performed to analyze influencing factors.Results:A total of 410 questionnaires were distributed, and 405 valid questionnaires were returned, with an effective recovery rate of 98.78% (405/410). Among them, 150 patients were PTSD-positive. Binary Logistic regression analysis showed that educational level, monthly family income, psychological resilience, and coping style were influencing factors for PTSD in postoperative breast cancer patients ( P<0.05) . Conclusions:Low education level, low income, and negative coping style are risk factors for PTSD in postoperative breast cancer patients; positive coping style and high psychological resilience are protective factors. Clinical practitioners should develop preventive or intervention measures based on these influencing factors to reduce the occurrence of PTSD in postoperative breast cancer patients.

Sarcopenia,also known as"oligomyositis""hypomyositis"and"muscle wasting",is an age-related geriatric syndrome characterized by decreased muscle mass,muscle strength and function decline.It can increase the risk of adverse out-comes such as physical disability,poor quality of life,and death.The pathogenic factors of sarcopenia mainly include older age,diseases,lack of exercise,malnutrition,etc.As one of the key factors affecting sarcopenia,the nutritional status of the body play an important role in the development of sarcopenia.Therefore,this paper reviews the role of nutrition in sarcopenia and nutritional interventions for patients with common chronic diseases combined with sarcopenia,aiming to provide a basis for the developing more scientific and rationalized nutritional intervention program for elderly patients with sarcopenia.

Abstract Vaccination is the most effective prevenative measure against infectious diseases. As guardians of minor children, parental attitudes have a decisive influence on children s vaccination. Therefore, it is very important to understand parental attitudes and preference towards the vaccination of minor children in COVID-19 for the successful implementation of vaccination. In this study, the current situation and associated factors of parental COVID-19 vaccine hesitancy for children. It was found that parental vaccine hesitation was mainly influenced by factors related to parents, children, vaccination and information process. Parents should be guided to obtain information through authoritative channels and treat vaccination correctly. At the same time, medical staff should play an important role in health education, submit correct immunisation information, reduce vaccine hesitancy, and promote herd immunity.

Objective:To explore inner ear mechanism of 6-gingerol，an active ingredient of ginger，for resisting motion sickness in rats.Methods:By stimulating SD rats with rotation，so as to induce conditioned anorexia to 0.15% saccharin solution，thus simulating motion sickness. Using qRT-PCR，western blotting，ELISA，and other related biological techniques to detect aquaporin 2（AQP2），plasma arginine vasopressin（AVP）V2 receptor（V2R），transient receptor potential ion channel 4（TRPV4）mRNA，and protein expression levels of the rats’ inner ears，and observe the impact of TRPV4 antagonist ruthenium red on the effect of 6-gingerol countering motion sickness.Results:After 6-gingerol inhibited the rotational stimulation，the expression levels of AQP2 mRNA and protein in the inner ear of rats were significantly increased（ P<0.05），the TRPV4 mRNA and protein expression levels were significantly decreased（ P<0.05），and the expression levels of V2R mRNA and protein were decreased（ P<0.05）. After using ruthenium red（5 mg/kg）alone，the reduction of drinking saccharin in rats was significant（ P<0.01）. The 6-gingerol combing with ruthenium red（5 mg/kg）could eliminate the inhibitory effect of 6-gingerol pretreatment on the reduction of saccharin drinking in rats after rotational stimulation（ P<0.01）. Conclusion:The mechanism of 6-gingerol for resisting motion sickness may be related to its impact on the transcriptions and expressions of V2R and TRPV4 in inner ear，and then on the AQP2 expression.

Objective:To explore combined detection of mad2 with anti-nuclear mitotic spindle apparatus antibody(MSA)and anti-centromere antibody(ACA)and their clinical value for the diagnosis of small cell lung cancer(SCLC).Methods:One hundred and twen-ty SCLC patients,110 non-small cell lung cancer(NSCLC)patients,and 115 pulmonary nodule(PN)patients were enrolled in this study. The expression of mad2 was analyzed by qt-PCR.MSA and ACA were detected by indirect immunofluorescence(IIF)staining.Results:mad2 was overexpressed in SCLC and NSCLC samples(P<0.05).There were significant differences between the results obtained for SCLC and NSCLC samples by qt-PCR(P<0.05).AUC in ROC curve for mad2 expression was 0.799 with an intermediate diagnostic value. In the correlative analysis,the odds ratio of MSA and ACA was 6.94 and 5.60,respectively.In the correlation analysis,Kappa value of mad2 with MSA was 0.49,and Kappa value of mad2 with ACA was 0.42.In the parallel analysis,the sensitivity and specificity was 83.31% and 79.34%,respectively,while the Youden Index was 0.62.Moreover,in the serial analysis,the sensitivity and specificity was 65.32% and 93.35%,respectively,and the Youden Index was 0.59.Conclusions:In comparison with the NSCLC and PN samples,mad2 was overexpressed in SCLC samples.Therefore,mad2 ought to play a critical role in the pathology of SCLC.The combined expression of mad2 with MSA and ACA may contribute to enhancing the sensitivity and specificity of detection;this expression may allow early diag-nosis and clinical diagnosis of SLCC and may be a promising treatment for SCLC.

Objective To explore the principal component analysis (PCA)-Logistic regression model in predicting hospital-acquired pneumonia (HAP) in patients with craniocerebral injury, and find the influencing factors of mortality and HAP occurrence in patients with craniocerebral injury. Methods One hundred and eight patients with craniocerebral injury, admitted to our hospital from December 2011 to November 2017, were chosen in our hospital. Clinical diagnoses, 36 treatment indicators and laboratory results were constituted the original data set; 12 principal components with cumulative contribution>2/3 were extracted as independent variables, and mortality and HAP occurrence were as dependent variables to establish PCA-Logistic regression model. Receiver operating characteristic (ROC) curve was applied to forecast performance of PCA-R model. Results PCA-Logistic regression showed that 4 principal components had significant influence in mortality, and 5 principal components had significant influence in HAP outcomes. Open craniocerebral injury and coagulation changes were the clinical indexes with the highest coefficient when mortality was the outcome index. Gender and parenteral nutrition were the clinical indexes with the highest coefficient when HAP was outcome index. PCA-R model was able to identify the risk factors and forecast the clinical outcomes (HAP, sensitivity:83.9％, specificity: 94.8％, area under the curve [AUC]: 0.949; mortality, sensitivity: 92.3％, specificity:93.7％, AUC: 0.983). Conclusion PCA-Logistic regression model can effectively mine the clinical variables of patients with craniocerebral injury; insufficiency of blood perfusion after severe craniocerebral injury is an important factor affecting the survival of patients, and abnormal nutritional support may be an important clinical factor affecting the occurrence of HAP in patients.
