Objective To investigate the correlation between gut microbiota characteristics and immunotherapy efficacy in patients with advanced microsatellite stable (MSS) advanced gastrointestinal tumors. Methods Thirty patients with advanced MSS gastrointestinal tumors, including fourteen cases of gastric cancer and sixteen cases of colorectal cancer, who were admitted from November 1, 2022, to July 31, 2025 were enrolled. All patients underwent gut microbiota testing and received corresponding interventions on the basis of the results, followed by treatment with antiangiogenic agents combined with immunotherapy. Some patients additionally received probiotics or fecal microbiota transplantation. The primary endpoints were disease control rate (DCR) and objective response rate (ORR). The secondary endpoints were progression-free survival (PFS) and overall survival (OS). Univariate and multivariate Cox regression analyses were used to assess potential prognostic factors. Results Among the thirty patients, no complete response was observed. Two cases of partial response (PR), twelve cases of stable disease, and sixteen cases of progressive disease were recorded. The ORR was 6.7%, and the DCR was 46.7%. The median PFS was 6.4 months, and the median OS was 8.3 months. Both PR patients were classified as having a medium risk of gut microbiota dysbiosis and exhibited a Bacteroides-dominated enterotype. Multivariate analysis indicated that tumor type, liver metastasis, and bone metastasis were potential prognostic factors for PFS and OS. Conclusion Patients with a medium risk of gut dysbiosis may exhibit a relatively favorable response to immunotherapy, suggesting that gut microbiota status could serve as a potential biomarker for predicting treatment efficacy in advanced MSS gastrointestinal tumors.

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 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 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.

Objective To establish the methods of galvanic vestibular stimulation-vestibular evoked myogenic potentials(GVS-VEMPs)in healthy children and to obtain the normal value of GVS-cVEMP and GVS-oVEMP in these children in China.Methods Twenty(3～14 years)healthy children and 24 healthy adults(18～30 years)were enrolled for conventional examinations of GVS-cVEMP and GVS-oVEMP.Using the galvanic stimulation in-tensity under 3 mA/1 ms for children and 5 mA/1 ms for adults.The characteristics of elicitation and parameter re-sults of GVS-cVEMP and GVS-oVEMP in children and adults,as well as the pain scores and the elicitation of differ-ent stimulus intensities in the two age groups were recorded.Results The elicitation of GVS-cVEMP and GVS-oVEMP were both 100.0％in children and adult groups.The p1 latency,n1 latency and p1-n1 interval latency of GVS-cVEMP were 10.46±1.84 ms,16.98±2.12 ms and 6.52±1.42 ms respectively in children group,the n1 la-tency and p1-n1 interval latency were significantly shorter than the adult group(P＜0.05).The n1 latency,p1 la-tency and p1-n1 interval latency of GVS-oVEMP were 8.87±1.40 ms,12.25±1.80 ms and 3.39±1.07 ms re-spectively in children group with no significant difference between the two groups.The thresholds of GVS-cVEMP and GVS-oVEMP in children group were significantly lower than adult group(P＜0.01),but no differences were found in adult group regarding on the amplitude and interaural amplitude asymmetry ratio.In addition,with the in-crease of the intensity of galvanic stimulation,the correlation between pain scores and the elicitation rates of GVS-cVEMP and GVS-oVEMP also increased.Conclusion Using appropriate stimulus intensity and recording methods,GVS-cVEMP and GVS-oVEMP could be successfully assessed and detected in healthy children over 3 years old and adolescents.The latency of GVS-cVEMP in children is slightly shorter than that in adults,therefore we recommend selecting the matched age group for assessment in the children group.

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.
