Cirrhotic portal hypertension is a clinical syndrome caused by persistently elevated portal venous pressure due to liver cirrhosis and can lead to a series of complications， among which esophagogastric variceal bleeding has become one of the most severe complications due to sudden onset and a high mortality rate. Since the release of Expert consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension （2019 edition）， significant advances have been achieved in this field in China and globally. In order to formulate an expert consensus aligned with the situation of China， Chinese Society of Surgery， Chinese Medical Association organized and compiled Expert Consensus on diagnosis and treatment of esophagogastric variceal bleeding in cirrhotic portal hypertension （2025 edition）. This article elaborates on the key updates in the new edition and explores the major differences between the old and new editions， in order to enhance the understanding of the new edition among clinicians and provide a reference for clinicians in clinical work.

ObjectiveTo systematically clarify the expression profile of splicing factor 3B subunit 6 （SF3B6） in pancreatic cancer， its clinical prognostic value， and its regulatory effect on the malignant phenotype of cancer cells through bioinformatics analysis， clinical sample validation， and in vitro functional experiments， and to assess its potential as a novel tumor biomarker. MethodsTranscriptomic and clinical data were downloaded from The Cancer Genome Atlas and Xena public databases at The University of California Santa Cruz to investigate the difference in the expression of SF3B6 between pancreatic cancer tissue and normal pancreatic tissue， and the association of SF3B6 with the prognosis and clinical indices of patients with pancreatic cancer was analyzed. Three pancreatic ductal adenocarcinoma cell lines and one normal pancreatic ductal epithelial cell line were cultured， and RT-qPCR was used to measure the expression level of SF3B6 in pancreatic cancer. A total of 43 patients with pancreatic cancer who underwent surgery in Binzhou Medical University Hospital from January 2024 to December 2025 were enrolled as subjects， and Western blot and RT-qPCR were used to measure the expression of SF3B6 in pancreatic cancer tissue. Based on the median expression level of SF3B6 measured by RT-qPCR， the patients were divided into high and low expression groups. The association of SF3B6 expression with clinical features and prognosis was assessed. A pancreatic cancer cell line with stable low SF3B6 expression was constructed， and CCK-8 assay and Transwell migration and invasion assays were used to observe the impact of SF3B6 on the biological behaviors of the pancreatic cancer cell line， including proliferation， migration， and invasion. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and a one-way analysis of variance was used for comparison between multiple groups， while the least significant difference t-test or the Games-Howell test was used for further comparison between two groups； the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups. The chi-square test was used for comparison of categorical data between two groups. A Logistic regression analysis was used to investigate the influencing factors for the expression of SF3B6， and the univariate and multivariate Cox proportional-hazards regression model analyses were used to investigate the risk factors for prognosis. ResultsThe bioinformatics analysis showed that SF3B6 was highly expressed in pancreatic cancer tissue （P<2.2×10^-16） and significantly affected the overall survival （P=0.011） and progression-free survival （P=0.002） of patients with pancreatic cancer. Sex， age， clinical stage， and TNM stage were not influencing factors for SF3B6 expression （all P>0.05）， and SF3B6 could be used as an independent risk factor for the survival outcome of patients with pancreatic cancer （overall survival： hazard ratio=2.26， 95% confidence interval： 1.13 — 4.50， P=0.021； progression-free survival： hazard ratio=2.37，95% confidence interval： 1.22 — 4.58， P=0.010）. Cellular and tissue experiments confirmed the high expression level of SF3B6 in pancreatic cancer cell lines （P<0.05）， and the expression level of SF3B6 increased with the increase in the malignancy of pancreatic cancer， showing the highest relative expression level in PANC-1 cells with the highest degree of malignancy； the expression level of SF3B6 in the solid tissue of pancreatic cancer was significantly higher than that in paracancerous tissue （P<0.01）. The expression level of SF3B6 might affect the overall survival of patients with pancreatic cancer （P<0.05）， while it showed no significant association with age， sex， pathological grade， maximum tumor diameter， or clinical stage （all P>0.05）. Knockdown of SF3B6 significantly inhibited the proliferation， migration， and invasion of pancreatic cancer cells （all P<0.01）. ConclusionSF3B6 is highly expressed in pancreatic cancer， and the high expression of SF3B6 can promote the proliferation， migration， and invasion of pancreatic cancer cells. Therefore， SF3B6 can be used as a potential biomarker for prognostic evaluation.

Objective: To explore the relative importance of different food attributes and levels in food decision making of school aged children, and to understand their meal preferences, so as to provide the evidence for formulating precise intervention strategies for dietary behaviours of school aged children. Methods: From May to June 2024, a total of 854 children aged 11 to 15 years old were selected from 2 middle schools (each school in urban and rural areas) in both Hubei Province and Anhui Province by stratified cluster random sampling method to conduct a D-optimal discrete choice experiment. The mixed Logit model was used to analyze children s preference for meal attributes and different levels, and to calculate the relative importance (RI) of attributes and willingness to pay (WTP) in meal choices. Results: The included five food attributes had statistical significance on meal choice of school aged children ( P <0.05). The relative importance of food attributes affecting the meal choices of school aged children in descending order were dining mode ( RI =31.26%), food varieties ( RI =30.56%), cooking method( RI =23.84%), taste( RI =8.06%) and price ( RI =6.27%). Among them, school aged children preferred home cooked meals ( β =0.74) (WTP=86.3 yuan),varied foods(grain/tubers+vegetables+fish, meat, eggs and beans) ( β =0.61) (WTP=71.9 yuan), fried/roasted cooking ( β =0.51) and spicy taste ( β =0.33).Price was negatively correlated with meal choices( β =-0.01) ( P <0.05). Based on residential area and body mass index (BMI), the stratified analysis showed that dining mode was highest in the relative importance for rural children with overweight and obese children ( RI =31.28%,34.17%), both of whom preferred home cooked meals ( β =0.76, 0.91), and meals containing fish, meat, eggs and beans with grain/tubers or grain/tubers and vegetables in terms of food choice (area: β =0.53, 0.53 ; BMI: β =0.55, 0.56) ( P <0.05). Conclusions School aged children have different preferences for different attributes of meals. The quality of school meals should be improved,the cost of buying healthy meals should be reduced,targeted family health education should be carried out,and healthy cooking methods should be advocated.

Objective:To investigate the application value of needle-knife accurate fistulo-tomy (NKAF) for difficult biliary cannulation during endoscopic retrograde cholangiopancreato-graphy (ERCP).Methods:The retrospective and descriptive study was conducted. The clinicopatho-logical data of 137 patients with difficult biliary cannulation during ERCP at Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine between January 2021 and December 2022 were collected. There were 51 males and 86 females, aged (69±13)years. All 137 patients received NKAF for cannulation during ERCP. Observation indicators: (1) surgical situations; (2) complications. Measurement data with normal distribution were represented as Mean± SD. Count data were repre-sented as absolute numbers. Results:(1) Surgical situations. Of 137 patients, 136 cases had succe-ssful cannulation, 1 case had failed cannulation with NKAF following unsuccessful double-guidewire technique. In the 136 successful cases, the endoscope was straightened in 42 cases, left in a long position in 37 cases, and maintained in the standard position in 57 cases. The cannulation time was (90±8)s. (2) Complications. The serum amylase at postoperative 6 hours in the 136 successful cases was (163±23)U/L. No patient developed post-ERCP pancreatitis. Of the 136 patients with successful cannulation, one case experienced post-sphincterotomy bleeding, which was observed oozing from the papillary orifice on emergency gastroscopy. The patient was successfully controlled with endoscopic clips.Conclusion:NKAF is safe and effective for difficult biliary cannulation during ERCP.

Objective To employ three dimensional high-resolution vessel wall magnetic resonance imaging(3D hr-VW-MRI)for analyzing the imaging characteristics of posterior circulation non-stenotic intracranial atherosclerotic plaque and to discuss its diagnostic value in identifying culprit plaques.Methods Ninety-three patients(age[62.94±9.70]years old,67 males,26 females)with non-stenotic atherosclerosis in our hospital from Jan.2019 to Jan.2021 were retrospectively recruited.The imaging features of plaques,including luminal area,maximum wall thickness and minimum wall thickness at the most stenotic site,stenosis rate,plaque burden,remodeling index,eccentricity index,enhancement ratio at the most stenotic site,and intraplaque hemorrhage,were measured based on T1-weighted imaging(T1WI)and contrast-enhanced T1WI.The culprit plaque was defined as a lesion arising from the responsible vascular supply area to a fresh infarction on the diffusion weighted imaging(DWI)and T2 fluid attenuated inversion recovery(T2-FLAIR)images with accompanying ischemic stroke/transient ischemic attack(TIA).A plaque was considered to be a nonculprit plaque when it occurred in patients with presumed ischemic stroke/TIA,but without an infarct on DWI and T2-FLAIR.Results Sixty-one culprit plaques and 32 non-culprit plaques were analyzed.The proportions of patients with hyperlipidemia,National Institutes of Health stroke scale(NIHSS)score,narrowest plaque enhancement rate,and incidence of intraplaque hemorrhage in the culprit plaque group were significantly higher than those in the non-culprit plaque group(all P＜0.05).Multivariate logistic regression analyses showed that NIHSS score(odds ratio[OR]=1.799,95％confidence interval[CI]1.303-2.484,P＜0.001),enhancement ratio(OR=1.076,95％CI 1.027-1.128,P=0.002)and intraplaque hemorrhage(OR=30.708,95％CI 2.563-367.925,P=0.007)were associated with plaque type.Conclusion NIHSS score,enhancement ratio at the most stenotic site,and intraplaque hemorrhage are independent risk factors for culprit plaques in patients with posterior circulation non-stenotic intracranial atherosclerotic disease.These indicators may help identify such culprit plaques and could be used to screen individuals with plaques having these characteristics,thereby providing a basis for early preventive interventions.

Objective:To explore the potential categories of symptom characteristics of early breast cancer patients undergoing postoperative chemotherapy, analyze the differences of symptoms among different categories of patients, and compare their quality of life according to different categories.Methods:This was a cross-sectional study. From January to June 2023, 240 patients with early breast cancer who received chemotherapy after surgery in General Hospital of Ningxia Medical University were selected by convenience sampling. They were investigated by general information questionnaire, Memory Symptom Assessment Scale, and Functional Assessment of Caner Therapy-Breast Cancer. Mplus 8.3 was used to carry out potential profile analysis and identify the potential categories of symptom characteristics of early breast cancer patients undergoing postoperative chemotherapy. Binary Logistic regression analysis was used to determine the influencing factors of symptom characteristics. SPSS 26.0 software was used to compare the differences in quality of life scores of patients undergoing postoperative chemotherapy for different categories of early breast cancer.Results:Totally 233 valid questionnaires were ultimately collected, with an age of 50.85 ± 8.09. There were two potential categories of postoperative chemotherapy patients with early breast cancer: low symptom troubled group (159 cases, 68.2%) and high symptom troubled group (74 cases, 31.8%). The quality of life score of the high symptom distress group was (76.84 ± 13.15) points, which was significantly lower than (89.56 ± 11.29) points of the low symptom distress group, and the difference was statistically significant ( t=7.18, P<0.01). Logistic regression analysis showed that patients with early breast cancer who had financial burden after postoperative chemotherapy were more likely to belong to the group with high symptoms [ OR (95% CI) was 3.028 (1.434-6.394), P<0.01]. Postoperative chemotherapy patients with early breast cancer who had satisfactory sleep at night are more likely to belong to the group with low symptoms [ OR(95% CI) was 0.446 (0.217-0.920), P<0.05]. Conclusions:There is population heterogeneity in the symptom characteristics of patients with early breast cancer undergoing postoperative chemotherapy. and economic burden and night sleep are the influencing factors of symptom distress categories of breast cancer patients. It is suggested that medical staff should give individualized and targeted intervention measures centered on patients′ needs according to different types of population characteristics, so as to reduce the symptom burden and improve their quality of life.

Objective:To construct the supportive care intervention scheme for breast cancer radiotherapy patients based on the empowerment theory and discuss its application effect, so as to provide the reference for the clinical nursing intervention.Methods:According to the investigation results of the current situation of supportive care needs of patients with breast cancer radiotherapy and the results of literature review, a supportive care intervention scheme for breast cancer radiotherapy patients based on the empowerment theory was constructed by Delphi expert consultation method.Adopting experimental research, breast cancer radiotherapy patients in General Hospital of Ningxia Medical University were selected by convenient sampling method. They were divided into the control group from April to May 2023 (40 cases) for routine nursing care, and the experimental group from August to September 2023 (40 cases) for the supportive care intervention scheme for breast cancer radiotherapy patients based on the empowerment theory on the basis of routine nursing care according to the admission time. The 34-item Short-Form Supportive Cancer Needs Survey (SCNS-SF34), Strategies Used by People to Promte Health (SUPPH), Cancer Fatigue Scale(CFS) and Function Assessment of Cancer Therapy-Breast (FACT-B) were collected on the day of admission, the end of radiotherapy and 3 months after radiotherapy to evaluate the effects before and after intervention.Results:After 1, 2 rounds of expert correspondence, the positivity of experts were 95.24%(20/21) and 100.00%(20/20), the expert authority coefficient was 0.804 and 0.825, and the Kendall harmony coefficient was 0.129 and 0.138 (both P<0.05). Finally, a supportive care intervention scheme for breast cancer radiotherapy patients based on the enabling theory was formed, which included 5 primary items, 11 secondary items and 32 tertiary items.The application results showed that there were 37 cases in the control group with an age of (48.16 ± 10.21) years, and 38 cases in the experimental group with an age of (44.50 ± 9.81) years. All patients were female. There was no statistically significant difference in the scores of SCNS-SF34, SUPPH, CFS, and FACT-B between the two groups on the day of admission(all P>0.05). Three months after the end of radiotherapy, the score of SCNS-SF34 in the experimental group was (73.24 ± 11.99) points, which was lower than (79.91 ± 14.79) points in the control group, and the difference was statistically significant ( t=4.43, P<0.05). At the end of radiotherapy and 3 months after the end of radiotherapy, the scores of SUPPH in the experimental group were (80.39 ± 8.55) and (92.37 ± 8.14) points, respectively, which were higher than (73.95 ± 9.86) and (86.24 ± 7.10) points in the control group, and the difference was statistically significant ( t=-3.03, -3.47, both P<0.05). At the end of radiotherapy and 3 months after the end of radiotherapy, the scores of CFS in the experimental group were 30.00 (28.75, 33.00) and (25.29 ± 3.26) points, respectively, which were lower than 34.00 (31.50, 35.00) and (27.59 ± 3.43) points in the control group, and the difference was statistically significant ( Z=-3.51, t=2.98, both P<0.05). At the end of radiotherapy and 3 months after the end of radiotherapy, the scores of FACT-B in the experimental group were (85.08 ± 12.74) and (105.53 ± 6.53) points, respectively, which were higher than (79.03 ± 7.90) and (95.73 ± 7.61) points in the control group, and the difference was statistically significant ( t=-2.48, -5.99, both P<0.05). Conclusions:The supportive care intervention scheme for patients with breast cancer radiotherapy based on the empowerment theory established in this study is scientific and feasible, which can reduce patients' needs for supportive care, alleviate cancer-related fatigue, and improve self-management efficacy and quality of life.
