ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

Post-acute pancreatitis diabetes mellitus (PPDM-A) is a common type of exocrine pancreatic diabetes. It is very important to clarify the risk factors of PPDM-A and effectively screen for diabetes in patients with acute pancreatitis to prevent the occurrence and development of PPDM-A. This article elaborates on the three aspects of PPDM-A, including high-risk population, screening timing and methods, as well as PPDM-A screening in children and adolescents, aiming to provide a basis for early detection of PPDM-A and timely targeted treatment for patients.

Objective To identify the main challenges in the current development of the"one hospital with multiple campuses"model in Chinese public hospitals and provide evidence for policy improvement.Methods A systematic search of literature published between 2014 and 2024 on the topic of"one hospital with multiple campuses"was conducted in the CNKI database.The severity of the problems(Pc)was comprehensively calculated through biblio-metric analysis,and the severity ranking of the problems was determined accordingly.Results Twenty-five issues were categorized into nine dimensions.Key problems included significant inter-campus disparities in medical quality hindering homogenization(Pc=1.000);outdated information systems causing data-sharing barriers(Pc=0.945);overly complex management systems increasing unified management difficulties(Pc=0.922);unclear functional posi-tioning of branch campuses and lack of integrated planning(Pc=0.772);and fragmented information systems cou-pled with workforce redundancy elevating cost-control challenges(Pc=0.772).Conclusion The development of the"one hospital with multiple campuses"model in Chinese public hospitals urgently requires unified quality control stan-dards,strengthened cross-campus quality supervision systems,integrated information platforms to eliminate data silos,optimized organizational structures,and discipline-specific layouts.These measures will establish a manage-ment system tailored to the multi-campus model,achieving a virtuous cycle of"structural optimization—pro-cess coordination—outcome homogenization".

Objective To investigate the expression levels of microRNA-34a(miR-34a),β-catenin and pro-grammed death receptor-1(PD-L1)in cancer tissues of patients with cervical cancer(CC)and their correla-tion with patients' prognosis.Methods A total of 83 patients with CC admitted to Yuncheng Central Hospital Affiliated to Shanxi Medical University from June 2021 to January 2024 were selected as the research objects.General data,CC tissue and adjacent normal tissue samples of all patients were collected.The mRNA expres-sion levels of miR-34a,β-catenin and PD-L1 in CC tissues and adjacent normal tissues were detected by fluo-rescence quantitative PCR and compared.The expression levels of β-catenin and PD-L1 in CC tissues and adja-cent normal tissues were detected by immunohistochemistry.Multivariate Logistic regression analysis was used to analyze the influencing factors of prognosis in CC patients.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of miR-34a,β-catenin and PD-L1 expression levels in CC pa-tients with poor prognosis.Results Compared with adjacent normal tissues,the expression level of miR-34a of the CC tissues was lower,while the expression levels of β-catenin and PD-L1 were higher(P＜0.05).The positive expression rates of β-catenin and PD-L1 protein in CC tissues were higher than those of adjacent nor-mal tissues(89.16％vs.10.84％,78.31％vs.20.48％,x2=101.807,55.526,P＜0.05).There were no sig-nificant differences in age and body mass index(BMI)between the good prognosis group and the poor progno-sis group(t=1.508,1.820,both P＞0.05),while there were significant differences in International Federa-tion of Gynecology and Obstetrics(FIGO)stage and differentiation degree between the two groups(x2=8.451,9.115,both P＜0.05).Compared with the good prognosis group,the expression level of miR-34a of the poor prognosis group was lower,while the expression levels of β-catenin and PD-L1 were higher(P＜0.05).Multivariate Logistic regression analysis showed that increased expression of miR-34a was an protective factor for poor prognosis in CC patients,while the increased expression levels of β-catenin and PD-L1,Ⅱ a and Ⅱ b FIGO staging and low differentiation were independent risk factors for poor prognosis in CC patients(P＜0.05).ROC curve analysis showed that miR-34a,β-catenin and PD-L1 all had certain predictive value for the poor prognosis of CC patient,and the area under the curve(AUC)of the single detection was 0.765,0.836 and 0.797,respectively.The AUC of the combined detection was 0.914(Z=2.631,2.331,2.571,P=0.009,0.020,0.010).Conclusion The expression levels of miR-34a,β-catenin and PD-L1 mRNA affect the prognosis of CC patients.Increased expression of miR-34a is an protective factor for poor prognosis in CC patients,in-creased β-catenin and PD-L1 expressions are independent risk factors for poor prognosis in CC patients,and all three factors can be used as biomarkers to predict poor prognosis in CC patients,and the combined detection of the three has the highest prognostic value.

Objective:To investigate the clinical characteristics of first-episode and recurrent acute hypertriglyceridemic pancreatitis (HTGP).Methods:The retrospective cohort study was con-ducted. The clinical data of 313 patients with HTGP admitted to 26 medical centers in China in the Chinese Acute Pancreatitis Clinical Research Group (CAPCTG)-PERFORM database from November 2020 to December 2021 were collected. There were 219 males and 94 females, aged 38(32,44)years. Of the 313 patients, 193 patients with first-episode HTGP were allocated into the first-episode group and 120 patients with recurrent HTGP were allocated into the recurrent group. Observation indica-tors: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) comparison of severity and prognosis in the course of disease within 14 days between the two groups; (3) the association between recurrent HTGP and the risk of persistent organ failure (POF); (4) follow-up. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Wilcoxon rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data was conducted using the Wilcoxon rank sum test. The Kaplan-Meier method was used to plot the cumulative recurrence rate curve and Log-Rank test was used for survival analysis. The Logistic regression model was used for multivariate analysis, and continuous variables were converted into categorical variables according to the mean value or common criteria. Propensity score matching was performed by 1∶1 nearest neighbor matching method, with caliper value of 0.02. Paired t test or Wilcoxon rank sum test and McNemar′s test were used for comparison between matched groups. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 313 patients,208 cases were successfully matched, including 104 cases in the first-episode group and 104 cases in the recurrent group. After propensity score matching, there was no significant difference in demographic characteristics, severity of illness scores and laboratory test between the two groups ( P>0.05). The elimination of gender, acute physiology and chornic health evaluation (APACHE) Ⅱ score, computed tomography severity index score, systemic inflammatory response syndrome score, sequential organ failure assessment score, apolipoprotein E, C-reactive protein, creatinine, lactic acid dehydrogenase, procal-citonin confounding bias ensured comparability between the two groups. (2) Comparison of severity and prognosis in the course of disease within 14 days between the two groups. There were signifi-cant differences in POF and local complications between the first-episode group and the recurrent group ( P<0.05). (3) The association between recurrent HTGP and the risk of POF. Results of uncor-rected univariate analysis showed that there was no association between recurrent HTGP and the risk of POF ( odds ratio=0.78, 95% confidence interval as 0.46-1.30, P>0.05). Results of multivariate analysis after adjusting for covariates such as gender, age, APACHE Ⅱ score, C-reactive protein, triglyceride and total cholesterol showed that compared with first-episode HTGP, recurrent HTGP was associated with a higher risk of POF ( odds ratio=2.22, 95% confidence interval as 1.05-4.71, P<0.05). Results of subgroup analysis showed that age<40 years was associated with an increased risk of POF ( odds ratio=3.31, 95% confidence interval as 1.09-10.08, P<0.05). (4) Follow-up. Twelve of the 313 patients died during hospitalization, including 9 cases in the first-episode group and 3 cases in the recurrent group. The rest of 301 surviving patients, including 184 cases in the first-episode group and 117 cases in the recurrent group, were followed up for 19.2(15.5, 21.9)months. Results of follow-up showed that for 184 survived patients of the first-episode group, 164 cases were followed up and 24 cases experienced recurrence, for 117 survived patients of the recurrent group,29 cases experienced recurrence, showing a significant difference between the two groups ( χ2=4.67, P<0.05). Conclusion:Compared with first-episode HTGP, patients with recurrent HTGP are more prone to POF and local complications, and are more prone to recurrence after discharge. The risk of POF in recurrent HTGP patients is 2.22 times that of those with first-episode, and the risk is higher in patients with age <40 years.

Objective:To construct a mouse model of dextran sulfate sodium salt (DSS)-induced inflammatory bowel disease and investigate the protective effect of Bifidobacterium animalis BB69 using that model. Methods:Forty C57BL/6J mice were randomly divided into five groups: normal control group (NC group), model group (DSS group), BB69 treatment group (BB group), mesalamine treatment group (MS group), and BB69 combined with mesalamine group (BM). Except for the NC group, the other four groups were given drinking water containing 2.3% DSS for 7 d and the corresponding intervention. The condition of mice in each group was observed.Results:Compared with the mice in the DSS group, those in the BB and MS groups showed significantly reduced disease activity index ( P<0.05), improved colon shortening and edema ( P<0.05), alleviated intestinal mucosal damage and inflammatory cell infiltration, and increased expression of intestinal tight junction protein ( P<0.05). Besides, the differentiation of Treg cells and the expression of anti-inflammatory cytokines were enhanced ( P<0.05). Conclusions:Bifidobacterium animalis BB69 has a significant protective effect on mice with experimental inflammatory bowel disease.

Background and Aims:The occurrence of duodenal fistula following infected pancreatic necrosis(IPN)in the later stage of treatment for acute necrotizing pancreatitis presents a significant clinical challenge.It often leads to severe complications such as difficulty in administering enteral nutrition,electrolyte imbalances,abdominal bleeding,and worsening infections.This study was performed to explore the efficacy of enteral nutrition combined with step-up drainage in treating IPN complicated by duodenal fistula and to share single-center experience. Methods:The clinical data of 66 patients with IPN complicated by duodenal fistula who underwent enteral nutrition combined with step-up drainage in the Severe Pancreatitis Treatment Center of the Nanjing Eastern Theater General Hospital between January 2018 and December 2020 were retrospectively analyzed. Results:Among the 66 patients,the median time from disease onset to the development of duodenal fistula was 53(32-75)d.In 46 cases(69.7％),suspicious digestive fluid-like discharge was observed from drainage tube or double-lumen tube.The diagnosis and location of the duodenal fistula were confirmed in 49 patients(74.2％)through fistulography,while the remaining cases were confirmed via surgical exploration or endoscopy.The duodenal fistulas were mainly located in the horizontal part(33.3％)or descending part(50.0％)of the duodenum.Nutritional access was safely established through nasojejunal tube in 61 patients(92.4％),while 5 patients(7.6％)required surgery to establish the access.Twenty patients(30.3％)experienced secondary abdominal bleeding,and 14 patients(21.2％)died.Among the 52 patients who recovered,49(94.2％)healed through step-up drainage,while 3(5.8％)required surgery due to delayed healing.Of the 49 patients who underwent non-surgical treatment,10(20.4％)achieved fistula closure through drainage tube,and 39(79.6％)achieved closure through continuous lavage drainage via double-lumen tube.The median healing time for duodenal fistula in non-surgically treated patients was 41(29-80)d. Conclusion:Patients with IPN complicated by duodenal fistula are in a critical condition.Enteral nutrition combined with step-up drainage is an effective treatment for these patients.
