Objective To explore the influence of the chronic disease management model based on wearable devices on the self-management ability,quality of life and physiological index control of patients after percutaneous coronary intervention(PCI).Methods Eighty patients with coronary heart disease who underwent PCI in Hefei BOE Hospital from April to September 2024 were selected as research objects.They were divided into control group and intervention group according to the random number table method,with 40 cases in each group.The control group received the conventional care model,while the intervention group adopted a postoperative chronic disease management model based on wearable devices,and the intervention period was 6 months for all.The coronary artery disease self-management scale(CSMS)was used to assess self-management ability,and the Seattle angina questionnaire(SAQ)was used to assess quality of life before and after the intervention.Additionally,the compliance rates of blood pressure,low density lipoprotein-cholesterol(LDL-C),and body mass index(BMI)were recorded.Results After the intervention,the scores of each dimension and total score of CSMS,as well as the scores of each dimension of SAQ of two groups of patients were significantly higher than those before the intervention(P＜0.05).Moreover,the scores of each dimension and total score of CSMS and the scores of each dimension of SAQ of intervention group were significantly higher than those of control group(P＜0.05).The compliance rates of blood pressure,LDL-C and BMI in intervention group were significantly higher than those in control group(P＜0.05).Conclusion The chronic disease management model based on wearable devices,through data monitoring,team collaboration and dynamic intervention,can significantly enhance the self-management ability of patients after PCI,improve their quality of life and the compliance rate of key physiological indicators,and has clinical promotion value.

Objective:To explore the value of magnetic resonance examination in distinguishing invasive and non-invasive pancreatic solid pseudopapillary neoplasms (SPN).Methods:The clinical and MRI data of 167 patients with SPN who underwent surgery and were pathologically diagnosed at Zhongshan Hospital ,Fudan University from Oct 2013 to Oct 2023 were retrospectively analyzed.Results:There was no statistically significant difference between invasive and non-invasive SPN in terms of age, gender, clinical symptoms, laboratory tests, location, growth pattern, tumor size, relationship with the pancreas, bleeding, and pancreatic duct dilation ( P>0.05). However, there were statistically significant differences between the two groups in terms of tumor morphology, margins, capsule, cystic solid ratio, pancreatic atrophy, enhancement pattern, and enhancement features ( P<0.05). The area under the ROC curve for the combined indicators (tumor morphology, margins, capsule, cystic solid ratio, and pancreatic atrophy) was 0.679 (95% CI: 0.594-0.764), with a sensitivity of 73.7% and specificity of 70.9%. Conclusion:Magnetic resonance examination is helpful in distinguishing invasive and non-invasive pancreatic solid pseudopapillary neoplasms.

Objective To translate the Health Behavior Scale for Cancer Patients(HBSCP)into Chinese and conduct reliability and validity tests.The measurement invariance of the Chinese version of the scale among differ-ent cancer patients was measured to form a health behavior scale suitable for assessing cancer patients in China.Methods The original scale was translated and translated back according to the Brislin translation model.The Chinese version of the HBSCP was formed through cross-cultural adaptation and pre-test.A questionnaire survey was conducted on 600 cancer patients from 2 tertiary A hospitals in Tianjin and Nanchang from February to July 2024 by convenience sampling method to test the reliability,validity,and measurement invariance of the Chinese version of the HBSCP.Results 567 valid questionnaires were collected.The Chinese version of the HBSCP in-cludes 9 items with 2 factors.Confirmatory factor analysis supported the 2-factor model,and all indexes meet the ideal fitting standard.The factor load of each item on the scale ranged from 0.697 to 0.815.The composite relia-bility of the 2 dimensions was 0.815 and 0.874.Average variance extracted was 0.656 and 0.526.The Chinese version of the HBSCP was positively correlated with Health Promoting Lifestyle Profile-Ⅱ(r=0.760,P＜0.001).The con-tent validity index of items ranges of the scales from 0.930 to 1.000,and the content validity index/average of the scales was 0.993.The total Cronbach's alpha coefficient of the scale was 0.900,and the two-factor Cronbach's alpha coefficient was 0.849 and 0.873,respectively.The scale has measurement invariance in the equivalence test for 3 clusters of lung,gastrointestinal,and gynecologic cancers.Conclusion The Chinese version of the HBSCP has good reliability and validity and measurement invariance across cancer types,and can be used to measure the health behavior level of cancer patients.

BACKGROUND/OBJECTIVES: The specific impact of different fruit and vegetable consumption categories on frailty is not completely understood. This study examined the relationships between the daily consumption of fruit and vegetables and frailty in a large general population. SUBJECTS/METHODS: This study used the data from the US National Health and Nutrition Examination Survey (2005–2020). Two intermittent 24-h dietary recalls were used to evaluate fruit and vegetable consumption. Frailty was assessed using the frailty index. Logistic regression, stratified analyses, and restricted cubic spline models were used to examine these associations. RESULTS: A higher daily intake of citrus, melons, and berries (odds ratio [OR], 0.77; 95% confidence interval [CI], 0.65–0.92), other fruit (OR, 0.74; 95% CI, 0.62–0.88), intact fruit (OR, 0.71; 95% CI, 0.60–0.84), dark-green vegetables (OR, 0.71; 95% CI, 0.60–0.83), and total vegetables (OR, 0.80; 95% CI, 0.66–0.96), along with a lower fruit juice intake (OR, 0.81; 95% CI, 0.69–0.96), were associated with a reduced risk of frailty in adults aged 18 yrs and older.Further analysis showed that the daily consumption of citrus melons and berries, other fruit, intact fruit, fruit juice, and tomatoes and tomato products were inversely associated with frailty in adults under 60 yrs and females. Dark green vegetables were inversely correlated with frailty in individuals aged 40–60 yrs and over 60 yrs, regardless of sex. CONCLUSION The daily consumption of most types of fruit, dark green vegetables, and tomatoes and tomato products may reduce the risk of frailty in American adults, particularly for individuals under 60 yrs of age and females.

Objective:To investigate the value of implantable cardiac monitor (ICM) in the diagnosis and treatment of patients over 60 years old with unexplained syncope.Methods:This was a multi-center, prospective cohort study. Between June 2018 and April 2021, patients over the age of 60 with unexplained syncope at Beijing Hospital, Fuwai Hospital, Beijing Anzhen Hospital and Puren Hospital were enrolled. Patients were divided into 2 groups based on their decision to receive ICM implantation (implantation group and conventional follow-up group). The endpoint was the recurrence of syncope and cardiogenic syncope as determined by positive cardiac arrhythmia events recorded at the ICM or diagnosed during routine follow-up. Kaplan‐Meier survival analysis was used to compare the differences of cumulative diagnostic rate between the 2 groups. A multivariate Cox regression analysis was performed to determine independent predictors of diagnosis of cardiogenic syncope in patients with unexplained syncope.Results:A total of 198 patients with unexplained syncope, aged (72.9±8.25) years, were followed for 558.0 (296.0,877.0) d, including 98 males (49.5%). There were 100 (50.5%) patients in the implantation group and 98 (49.5%) in the conventional follow-up group. Compared with conventional follow-up group, patients in the implantation group were older, more likely to have comorbidities, had a higher proportion of first degree atrioventricular block indicated by baseline electrocardiogram, and had a lower body mass index (all P<0.05). During the follow-up period, positive cardiac arrhythmia events were recorded in 58 (58.0%) patients in the ICM group. The diagnosis rate (42.0% (42/100) vs. 4.1% (4/98), P<0.001) and the intervention rate (37.0% (37/100) vs. 2.0% (2/98), P<0.001) of cardiogenic syncope in the implantation group were higher than those in the conventional follow-up group (all P<0.001). Kaplan-Meier survival analysis showed that the cumulative diagnostic rate of cardiogenic syncope was significantly higher in the implantation group than in the traditional follow-up group ( HR=11.66, 95% CI 6.49-20.98, log-rank P<0.001). Multivariate analysis indicated that ICM implantation, previous atrial fibrillation, diabetes mellitus or first degree atrioventricular block in baseline electrocardiogram were independent predictors for cardiogenic syncope (all P<0.05). Conclusions:ICM implantation improves the diagnosis and intervention rates in patients with unexplained syncope, and increases diagnostic efficiency in patients with unexplained syncope.

Objectives:To explore the impact of inositol-requiring enzyme 1(IRE1)signaling pathway on autophagy flux and cardiac function in mice with myocardial ischemia/reperfusion(I/R)injury. Methods:H9c2 cells were divided into control group,IRE1 group,oxygen glucose deprivation/reoxygenation(OGD/R)group,OGD/R+IRE1 group,chloroquine group,IRE1+chloroquine group,OGD/R+IRE1+chloroquine group,OGD/R+chloroquine group,OGD group,OGD+chloroquine group,OGD+IRE1+RNAi X-box binding protein 1(si-XBP1)group and OGD+IRE1+XBP1 overexpression(XBP1-OE)group.Autophagy flux of cells in each group was evaluated by autophagy double-labeled adenovirus(Adv-RFP-GFP-LC3).The nuclear translocation of X-box binding protein 1(XBP1)was analyzed by immunofluorescence and western blot.Adult male C57BL/6 J mice were randomly divided into sham operation group,I/R group,IRE1 group and I/R+IRE1 group(n=8 each).Cardiac function was evaluated by echocardiography.Quantitative western blot analysis was used to detect protein expression of autophagy-related molecules. Results:(1)Compared with OGD/R group,the expression level of IRE1 protein was significantly upregulated(P<0.001),and the expressions of microtubule-associated proteins light chain 3B(LC3Ⅱ)and sequestosome 1(p62)proteins were significantly decreased in IRE1+OGD/R group(all P<0.05).Compared with OGD/R+chloroquine group,the expression of LC3Ⅱ and p62 protein was significantly increased in OGD/R+IRE1+chloroquine group(all P<0.05).Compared with control group,the fluorescence intensity ratio of IRE1 nucleus/cytoplasm was significantly increased in OGD/R group(P<0.001),and further increased in IRE1+OGD/R group(P<0.001).The level of XBP1 in the nuclear protein was significantly higher in IRE1+OGD/R group than in OGD/R group(P<0.01).Compared with OGD/R+IRE1 group,the yellow punctures was significantly decreased in OGD/R+IRE1+si-XBP1 group(P<0.01),and significantly increased in OGD/R+IRE1+XBP1-OE group(P<0.05).(2)Compared with Sham group,the left ventricular ejection fraction(LVEF)and fractional shortening(FS)were significantly decreased in I/R group(both P<0.05),LVEF and FS reduction could be partly reversed in I/R+IRE1 group.Compared with Sham group,the number of autophagic vacuoles and the expressions of IRE1,LC3Ⅱ and p62 were significantly increased in I/R group(P<0.05).The number of autophagic vacuoles and the expression of p62 were significantly downregulated(both P<0.05),and the expressions of IRE1 and LC3Ⅱ in myocardial tissue were further increased in I/R+IRE1 group as compared to the I/R group(all P<0.05). Conclusions:IRE1 restores the blocked autophagy flux induced by OGD/R and I/R by promoting the nuclear translocation of XBP1,and the recovery of autophagy flux is associated with cardiac function improvement post I/R injury in mice.
