Objective To search,evaluate and summarise the best evidence on pre-rehabilitation before surgery for elderly patients with hip fracture so as to provide an evidence-based basis for further standardisation in clinical practice.Methods Based on the"6S Pyramid"evidence model,desktop searches were conducted across databases and websites including Medlive,BMJ Best Practice,UpToDate,the World Health Organization,the Guidelines International Network(GIN),British National Institute for Health and Care Excellence(NICE),American National Guideline Clearinghouse(NGC),Canadian Medical Association:Clinical Practice Guidelines Infobase(CMA),Scottish Intercollegiate Guidelines Network(SIGN),the Registered Nurses'Association of Ontario(RNAO),American College of Sports Medicine(ACSM),American Academy of Orthopaedic Surgeons(AAOS),European Society for Clinical Nutrition and Metabolism(ESPEN),American Society for Parenteral and Enteral Nutrition(ASPEN),the Enhanced Recovery After Surgery Society(ERASS),Cochrane Library,Joanna Briggs Institute,PubMed,CINAHL,Web of Science,Embase,Scopus,Science Direct,CNKI,Wanfang Data,Vip,and SinoMed.The research targeted evidence on pre-rehabilitation in elderly patients with hip-fracture before surgery,encompassing clinical decisions,guidelines,evidence summaries,best practices,expert consensus,systematic reviews and randomized controlled trials(RCTs).The search items spanned from the inception of database to 31st December,2023.Two researchers trained with evidence-based knowledge evaluated the quality of the included literature and extracted and summarised the evidence.Results A total of 14 documents were included,consisting of 2 clinical decisions,4 guidelines,1 best practice,4 expert consensus and 3 systematic reviews.Evidence was summarised into 7 domains from 25 pieces of evidence:multidisciplinary management,preoperative assessment,preoperative health education,multi-modal analgesia,nutritional management,exercise intervention and assessment and prevention of complication risks.Conclusion The best evidence summarised in this study provides a basis for pre-rehabilitation in elderly patients with hip fracture before surgery.Nurses should adapt the findings to specific contexts,standardise the preoperative rehabilitation procedures,and improve clinical outcomes for the patients.

Objective To investigate the potential role of plasma adiponectin concentration in predicting the response of patients with depression to electroconvulsive therapy(ECT).Methods This study enrolled depressive patients scheduled for ECT at the First Hospital of Shanxi Medical University between January 2022 and March 2024.Patients were categorized as either ECT responders(>50%reduction)or non-responders(≤50%reduction)based on post-ECT reduction rate of the 24-item Hamilton depression scale(HAMD)scores from baseline.Plasma adiponectin levels were measured in all patients before their first ECT treatment.To identify predictors of ECT response in patients with depression,the predictive value of plasma adiponectin was evaluated using receiver operating characteristic(ROC)curve analysis.Results A total of 80 patients with depression were enrolled including 44 in the ECT-responsive group and 36 in the non-responsive group.The plasma adiponectin level was significantly higher in the responsive group than in the non-responsive group[5.67(3.64,10.55)μg/mL vs.4.01(2.59,5.04)μg/mL,P=0.002].Pearson correlation analysis revealed a significant positive correlation between plasma adiponectin levels and the HAMD reduction rate(r=0.300,P=0.007).Multivariate logistic regression analysis showed that plasma adiponectin was independently associated with the response to ECT in patients with depression(OR=1.218,95%CI:1.009-1.470,P=0.040).Furthermore,ROC curve analysis demonstrated that the area under the curve(AUC)for adiponectin in predicting ECT response was 0.748(95%CI:0.583-0.813).Conclusion Pretreatment plasma adiponectin may serve as a potential biomarker for predicting response to ECT in patients with depression.

Objective:To investigate the application of time series models in forecasting pre-hospital emergency ambulance trips in Handan City and develop the LPro ensemble model for improved prediction accuracy to support emergency resource allocation.Methods:Pre-hospital emergency data from Handan Emergency Medical Command Center (2019-2023) were retrospectively analyzed. From 324 799 original records, 289 949 valid records were included after cleaning. The training set (2019-2022: 215 918 records) included 35 527 records in 2019, 52 015 in 2020, 61 836 in 2021, and 66 540 in 2022. The validation set (2023) contained 74 031 records. ARIMA, linear trend seasonal, exponential smoothing, and Prophet models were fitted to the training set. The LPro ensemble model was constructed using MAPE-based weighting (linear trend seasonal model: 0.38, Prophet: 0.62). Performance metrics included MAPE, RMSE, MAE, and R 2. Results:Data showed annual growth (compound annual growth rate 23.27%) and seasonal patterns (October peaks, February troughs). Ambulance dispatches increased annually with monthly cyclical patterns. For 2023 validation predictions: ARIMA (MAPE 8.76%, RMSE 619, MAE 491, R 2 0.4563), linear trend seasonal (MAPE 9.83%, RMSE 671, MAE 545, R 2 0.3608), Prophet (MAPE 8.43%, RMSE 562, MAE 503, R 2 0.5513), exponential smoothing (MAPE 8.08%, RMSE 643, MAE 410, R 2 0.4124). LPro model showed superior performance (MAPE 7.05%, RMSE 491, MAE 393, R 2 0.6570), with 16.37% lower MAPE, 12.63% lower RMSE, 21.87% lower MAE, and 19.17% higher R 2 versus Prophet. Conclusion:The LPro ensemble model substantially enhances prediction accuracy and reliability, offering scientific support for emergency resource optimization and dispatch scheduling in Handan City.

Objective:To investigate the perioperative safety, short-term and long-term efficacy, and surgical strategy of laparoscopic partial gastrectomy for gastrointestinal stromal tumors at the esophagogastric junction.Methods:Seventy-eight patients with mesenchymal tumors in the esophagogastric junction were retrospectively enrolled from September 2018 to August 2023 in which the upper edge of the tumor is less than 2 cm from the Z-line or has invaded the Z-line <1/2 circumference. There were 31 males (39.7%) and 47 females (60.3%), with an average age of (57.2±11.8) years and an average body mass index of (24.5±3.5) kg/m 2. All cases were divided into the wedge resection (WR) group ( n=51) and the resection by opening all of the layers of the stomach wall (RASW) group ( n=27) according to the surgical methods. Surgical outcomes, complications, recover and postoperative gastroesophageal reflux of both groups were compared. The measurement data with a normal distribution were represented by mean±standard deviation ( ± s), and values were compared using the independent sample t-test. The measurement data with a skewed distribution were represented by median (interquartile range) [ M( Q1, Q3)], and values were compared using the Mann-Whitney U test. Count data were expressed as examples (percentages) [ n(%)], and the χ2 test was used to compare countable data. A non-parametric test was used to compare the grade data. Results:The WR group had shorter operation time [(97.1±32.6) min vs (149.9±54.9) min, t=-5.33, P<0.001], less intraoperative blood loss [15(10, 20) mL vs 20(10, 50) mL, z=-2.47, P=0.014], shorter postoperative exhaust time [2(1, 3) d vs 3(2, 3) d, z=-2.49, P=0.013], shorter postoperative oral intake time [2(2, 3) d vs 4(2, 5) d, t=-3.70, P<0.001], shorter postoperative semi-liquid diet time[5(4, 6) d vs 7(5, 8) d, z=-3.57, P<0.001], and shorter postoperative hospital stay [5(4, 6) d vs 7(6, 8) d, z=-4.16, P<0.001] than the RASW group, with statistically significant differences. There was no significant difference in short-term (≤30 days) complications between the two groups (2.0% vs 3.7%, z=-0.46, P=0.648). No cases of cardia stenosis occurred in either group. In the WR group, 3 patients developed gastroesophageal reflux at 6 months postoperatively, with 2 patients relieved after taking acid-suppressing drugs and 1 patient not completely relieved. In the RASW group, 1 patient developed gastroesophageal reflux at 6 months postoperatively and was not completely relieved after taking acid-suppressing drugs. No other patients had gastroesophageal reflux. No other patients have gastroesophageal reflux. Conclusions:WR and RASW are safe and feasible for mesenchymal tumors at the esophagogastric junction in which the upper edge of the tumor is less than 2 cm from the Z-line or has invaded the Z-line <1/2 circumference, and has achieved an excellent short-term effect. The choice of surgical approach can be determined based on varions factors such as the location of the tumor, the relationship of the position between the tumor and the cardia, and whether the tumor is exophytic growth.

Objective: To investigate the scientific research capacity building of administrative offices of Centers for Disease Control and Prevention (CDCs) across 31 provinces (autonomous regions, municipalities), the Xinjiang Production and Construction Corps, and 5 separately listed cities in China, so as to provide the reference for improving the positioning of office functions and promoting the enhancement of scientific research capabilities. Methods: A self-administered questionnaire survey was conducted among heads and staff members of administrative offices in 37 CDCs. Data on office setup, general information, staffing, scientific research incentive measures and outputs were collected and analyzed. Results: The 37 administrative offices of the CDCs had an average authorized staffing size of 12 personnel. There were 17 of them setting independently allocated budgets. A total of 511 staff members were surveyed, comprising 238 males and 273 females, resulting in a male-to-female ratio of 0.87∶1. In terms of educational attainment, the majority held bachelor's degrees (225 individuals, 44.03%) or master's degrees and above (157 individuals, 30.72%). Professional technical personnel constituted the main occupational category, 302 individuals accounting for 59.10%. Intermediate professional titles were most common, 138 individuals accounting for 27.00%. From 2021 to 2023, a total of 68 research incentive measures have been implemented, and 579 personnel have received further training. These offices cumulatively led or participated in 80 scientific research projects and published 253 papers. Sixteen offices reported 10 and above scientific research outputs. These offices generally exhibited higher proportions of independently allocated budgets, greater numbers of senior professional titles, more staff with master's degrees or above, more implemented research incentive measures, and higher frequencies of staff further trainings. Conclusions The staff in the administrative offices of CDCs generally have a high level of educational attainment and include a significant number of professional technical personnel. However, their scientific research capacity remains relatively underdeveloped. It is recommended to conduct targeted professional training and research-focused lectures to enhance research literacy, leverage the strengths of multidisciplinary backgrounds, and promote cross-departmental and cross-institutional scientific research activities.

In recent years, idiopathic macular hole (IMH) surgery has a very high success rate due to the development of small-gauge vitrectomy, while the recovery of visual acuity is not satisfactory.Current studies have found that continuity of retinal blood vessels in the macular area and changes in retinal and choroidal perfusion are closely related to the formation and healing of MH, and have a significant impact on the visual prognosis in IMH patients.This article reviews the research progress on variations of parameters for retinal and choroidal vessels in IMH patients, as well as their relationship with visual prognosis.For retinal parameters, the changes in the foveal avascular zone, superficial and deep capillary plexus density, paracentral intraretinal cystoid spaces, retinal vessels position are discussed.Relevant research related to choroidal blood flow perfusion changes and the effects of different surgical methods on macular perfusion in patients with IMH are summarized to provide basis for further understanding the etiology and prognosis of IMH.

Objective To investigate whether Piceatannol(PIC)improves diabetic retinopathy(DR)mediated by microglial polarization and to elucidate the underlying molecular mechanisms.Methods Network pharmacology and bioinformatics were used to analyze the common targets of DR,PIC,and microglia.Human retinal vascular endothelial cells(HRVECs)were cultured in vitro and randomly divided into the NG-HRVECs group,HG-HRVECs group,and HG+PIC-HRVECs group.Cell viability was assessed by the CCK-8 assay,apoptosis was detected by the TUNEL assay,and the concentrations of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)were measured using ELISA kits.BV-2 cells were cultured in vitro and randomly divided into the NG-BV-2 group,HG-BV-2 group,HG+PIC-BV-2 group,HG+Si-NC-BV-2 group,HG+Si-CXCR4-BV-2 group,and HG+Ibrutinib-BV-2 group.The levels of arginase-1(Arg-1)and inducible ni-tric oxide synthase(iNOS)were measured using ELISA kits.Furthermore,conditioned medium(CM)from BV-2 cells of each group was collected to treat HRVECs,after which the viability,apoptosis rate,and TNF-α and IL-6 concentrations of the HRVECs were measured.A DR rat model was established and intervened with PIC to investigate the ameliorative effects of PIC on retinal pathology.Results Bioinformatics analysis identified CXCR4 as the key target of this study.Compared with the NG-HRVECs group,the apoptosis rate and the concentrations of TNF-α and IL-6 were increased in the HG-HRVECs group.Compared with the HG-HRVECs group,the HG+PIC-HRVECs group showed a decreased apoptosis rate and reduced concentrations of TNF-α and IL-6(all P＜0.05).Compared with the NG-BV-2 group,the HG-BV-2 group ex-hibited decreased Arg-1 levels and increased iNOS levels.Compared with the HG-BV-2 group,the HG+PIC-BV-2,HG+Si-CXCR4-BV-2,and HG+Ibrutinib-BV-2 groups all showed increased Arg-1 levels and decreased iNOS levels(all P＜0.05).Compared with the NG-BV-2-CM group,the HG-BV-2-CM group led to decreased viability,increased apoptosis rate,and in-creased concentrations of TNF-α and IL-6 in HRVECs.In contrast,the HG+PIC-BV-2-CM,HG+Si-CXCR4-BV-2-CM,and HG+Ibrutinib-BV-2-CM groups reversed the effects induced by HG-BV-2-CM on HRVECs(all P＜0.05).Animal experiment results showed that compared with DR model rats,rats treated with different doses of PIC exhibited significantly ameliora-ted retinal histopathological damage,and the protein expressions of Arg-1,iNOS,CXCR4,and p-BTK were reversed.Con-clusion PIC ameliorates DR progression mediated by microglial polarization by inhibiting the CXCR4/BTK pathway.

Objective To explore the different potential subtypes of psychosocial adaptation among young and middle-aged stroke patients,and analyze the relationship between different potential subtypes and quality of life,so as to provide references for the subsequent development of targeted interventions.Methods A total of 406 young and middle-aged stroke patients in 4 tertiary hospitals in Suzhou from June 2023 to June 2024 were recruited by convenience sampling.The General Information Questionnaire,the Self-Report Psychosocial Adjustment to Illness Scale and the EuroQol five-dimensional questionnaire were conducted for investigation.Latent profile analysis was used to explore the potential subtypes of psychosocial adaptation among young and middle-aged stroke patients.Generalized linear regression analysis was conducted with quality of life as dependent variables.Results A total of 380 young and middle-aged stroke patients were included.The psychosocial adaptation of patients could be classified into 3 potential subtypes:high adaptation level type(23.90％),medium adaptation level with health concerns type(46.40％),and low adaptation level with psychological barriers type(29.70％).The results of generalized linear regression analysis showed that potential subtypes of psychosocial adaptation were the influencing factors for quality of life in young and middle-aged stroke patients(P＜0.05).Conclusion There was group heterogeneity in psychosocial adaptation among young and middle-aged stroke patients,and the potential subtype of psychosocial adaption was an important factor affecting the quality of life of patients.It is suggested that medical staff should focus on patients with low adaptation level with psychological barriers type,and take targeted interventions according to characteristics of different subtypes of patients,so as to improve their quality of life.

Purpose This study aims to analyze genetic mutations in patients with BCR ∷ABL negative myelopro-liferative neoplasms(MPN)and to explore their relationship with clinical features.Methods We retrospectively ana-lyzed the clinical data of 208 patients diagnosed with BCR ∷ABL negative MPN,which included 34 patients with poly-cythemia vera(PV),33 with essential thrombocytopenia(ET),and 141 with primary myelofibrosis(PMF).Mutations in driver genes were assessed in all patients.A total of 72 patients underwent next-generation sequencing(NGS)with 69-gene panel,and the relationship between gene mutations and clinical features were analyzed.Results Among the 208 MPN patients,at least one driver gene mutation(JAK2,CALR,MPL)was detected in 96.15％(200/208)of the patients.Only 0.48％(1/208)of the patients exhibited both JAK2 and CALR driver mutations.We analyzed the clinical data of 136 patients with only driver gene mutations to compare the relationship between the most common JAK2 mutations(identified in 110 patients)and clinical outcomes.The JAK2 mutation group demonstrated higher white blood cell(WBC)counts and lower platelet(PLT)counts compared to the group without JAK2 mutations.173 muta-tions in 40 genes were detected in 72 patients,per capita carried(2.40±1.40)mutations.TET2,ASXL1,and TP53 are the most prevalent non-driver gene mutations,with 44.4％(32/72)of patients exhibiting at least one mutation in these three genes.In comparison to patients without detected mutations in TET2,ASXL1,and TP53,those with muta-tions in these genes demonstrated lower hemoglobin(HGB)levels,a higher incidence of splenomegaly,and more se-vere bone marrow fibrosis.High-molecular risk category(HMR)mutations were detected in 22.22％(16/72)of the patients,and patients with HMR exhibited lower hemoglobin(HGB)levels,lower PLT counts,a higher likelihood of peripheral blood primitive cell percentage ≥ 1％,a greater incidence of splenomegaly,and more severe myelofibrosis.Mutations in the ASXL1 gene were exclusively observed in patients with PMF.Among the PMF patients with ASXL1 mutations(12 patients),there was a higher likelihood of having a peripheral blood primitive cell percentage of ≥1％,as well as a more severe degree of myelofibrosis.Conclusion Approximately 97％of patients with myeloproliferative neoplasms(MPN)exhibit positivity for driver genes,with a notably high mutation rate of the JAK2 gene.Each sub-group of MPN is characterized by distinct gene mutation patterns.Notably,ASXL1 mutations are exclusive to patients with primary myelofibrosis(PMF).Furthermore,PMF patients harboring ASXL1 mutations tend to demonstrate more pronounced bone marrow fibrosis and a greater proportion of blast cells in peripheral blood.
