ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

A chemical investigation of secondary metabolites (SMs) from Aspergillus nidulans resulted in the identification of five novel dioxopiperazine (DKP)-diphenyl ether hybrids, designated as diphenylemestrins A-E (1-5). These compounds 1-5 represent the first known dimers combining DKP and diphenyl ether structures, with compound 4 featuring an uncommon dibenzofuran as the diphenyl ether component. The structural elucidation and determination of absolute stereochemistry were accomplished through spectroscopic analysis and electronic circular dichroism (ECD) calculations. Notably, diphenylemestrin C (3) exhibited moderate cytostatic activity against NB4 cells, with a half maximal inhibitory concentration (IC₅₀) value of 21.99 μmol·L^-1, and induced apoptosis at higher concentrations.

Objective:To screen the main characteristic variables affecting the incidence of cardiovascular and cerebrovascular diseases,and to construct the Bayesian network model of cardiovascular and cerebrovascular disease incidence risk based on the top 10 characteristic variables,and to provide the reference for predicting the risk of cardiovascular and cerebrovascular disease incidence.Methods:From the UK Biobank Database,315 896 participants and related variables were included.The feature selection was performed by categorical boosting(CatBoost)algorithm,and the participants were randomly divided into training set and test set in the ratio of 7∶3.A Bayesian network model was constructed based on the max-min hill-climbing(MMHC)algorithm.Results:The prevalence of cardiovascular and cerebrovascular diseases in this study was 28.8％.The top 10 variables selected by the CatBoost algorithm were age,body mass index(BMI),low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),the triglyceride-glucose(TyG)index,family history,apolipoprotein A/B ratio,high-density lipoprotein cholesterol(HDL-C),smoking status,and gender.The area under the receiver operating characteristic(ROC)curve(AUC)for the CatBoost training set model was 0.770,and the model accuracy was 0.764;the AUC of validation set model was 0.759 and the model accuracy was 0.763.The clinical efficacy analysis results showed that the threshold range for the training set was 0.06-0.85 and the threshold range for the validation set was 0.09-0.81.The Bayesian network model analysis results indicated that age,gender,smoking status,family history,BMI,and apolipoprotein A/B ratio were directly related to the incidence of cardiovascular and cerebrovascular diseases and they were the significant risk factors.TyG index,HDL-C,LDL-C,and TC indirectly affect the risk of cardiovascular and cerebrovascular diseases through their impact on BMI and apolipoprotein A/B ratio.Conclusion:Controlling BMI,apolipoprotein A/B ratio,and smoking behavior can reduce the incidence risk of cardiovascular and cerebrovascular diseases.The Bayesian network model can be used to predict the risk of cardiovascular and cerebrovascular disease incidence.

Objective To explore the mechanism of curcumin in enhancing gemcitabine sensitivity by regulating pancreatic cancer cells.Methods In order to verify the effect of curcumin on p53 and NF-κB p65 nuclear translocation in pancreatic cancer cell PANC1,the pancreatic cancer PANC1 cells were treated with 0,10,20,30 μmol/L curcumin to obtain the blank group,10 μmol/L curcumin group,20 μmol/L curcumin group and 30 μmol/L curcumin group.The intracellular distribution of NF-κB p65 was determined by immunofluo-rescence staining under fluorescence microscope.The expression level of p53 protein in cells was determined by Western blot.The expression level of p53 mRNA was determined by reverse transcription-real-time fluo-rescence quantitative PCR.The combined use of miRstar and JASPAR softwares predicted to seek microRNA (miRNA) potentially regulated by NF-κB p65 nuclear translocation.The double luciferase reporting assay was used to respectively verify the relationship between miRNA and p53.In order to verify whether curcumin in-fect the sensitivity of PANC1 cell through NF-κB p65/miR-266-5p/p53 axis,the gemcitabine group was ob-tained by 10 μmol/L gemcitabine treating cells,and the curcumin combined gemcitabine group was obtained by 20 μmol/L curcumin and 10 μmol/L gemcitabine treating cells.After the cells were treated with curcumin (20 μmol/L) and gemcitabine (10 μmol/L),oligonucleotides mimic NC and miR-26b-5p mimic were trans-fected into cells,and the mimic NC group and miR-26b-5p group were obtained.pcDNA3.1 no-load plasmid and pcDNA3.1-p53 overexpression plasmid were transfected into cells,respectively,and the pcDNA3.1 group and p53 group were obtained.The cell activity was detected by MTT assay.The cellular apoptosis level was determined by Annexin V/PI double staining.Results Compared with the blank group,the intracellular p53 mRNA and protein expression levels in the various curcumin treated groups (10,20,30 μmol/L curcumin groups) all were increased.Compared with the blank group,the expression level of NF-κB p65 in the nucleus of 20μmol/L curcumin group was decreased.The miRstar and JASPAR prediction software found 8 miRNA that may be regulated by NF-κB p65 nuclear translocation,in which 3 miRNA had potential to target p53 genes,especially miR-26b-5p effect was most significant.The double luciferase report experiment confirmed that miR-26b-5p did interact with p53.Compared with the mimic NC group,the expression levels of p53 mR-NA and protein in the mimic miR-26b-5p group were decreased.Compared with the gemcitabine group,the cell viability in the curcumin combined gemcitabine group was decreased and the apoptosis rate was increased.Compared with the mimic NC group,the cell activity in the mimic miR-26b-5p group was increased and the apoptosis level was decreased.Moreover compared with the pcDNA3.1 group,the cell activity in the pcDNA3.1-p53 group was decreased and the apoptosis level was increased.Conclusion Curcumin reduces the expression of miR-26b-5p gene by inhibiting the nuclear translocation of NF-κB p65 protein,and then increase the p53 gene and protein expression,and enhance the sensitivity of pancreatic cancer cells to gemcitabine by the NF-κB p65/miR-26b-5p/p53 axis.

Objective:To investigate the geriatric nursing competency of undergraduate nursing interns in four schools of nursing in Beijing as well as the influencing factors, and to provide a reference for perfecting the geriatric nursing education system in colleges and universities.Methods:From October to November 2022, a cross-sectional survey was performed on 223 undergraduate nursing interns selected by convenience sampling from four schools of nursing in Beijing, with the use of a general information questionnaire and the Gerontological Nursing Competence instrument. A general linear regression model was established to explore the factors influencing the geriatric nursing competency of nursing interns.Results:The mean total score for gerontological nursing competency was (3.19±0.40). In all dimensions, the mean score was highest for "Providing a safe living environment for older persons" (3.40±0.47) and lowest for "Understanding the sexual needs of older persons" (2.78±0.73). The thought about whether gerontological nursing contents were enough and the level of motivation to study gerontological nursing courses were the factors affecting nursing interns' gerontological nursing competency ( P<0.05). Conclusions:The overall gerontological nursing competency of the nursing interns was at a medium level, with uneven competencies in different dimensions. Nursing schools should strengthen gerontological nursing course building and stimulate students' learning motivation to improve their gerontological nursing competency.

Objectives:This study aims to investigate the impact of different Low-Density Lipoprotein cholesterol(LDL-C)levels on progression of intermediate coronary stenosis,and the associated risk factors leading to the progression of such lesions. Methods:Data were collected on 219 consecutive patients admitted at the Fuwai Central China Vascular Hospital from January 2020 to February 2021,underwent angiographic examinations and diagnosed with intermediate coronary stenosis,with at least one follow-up angiography after 11 months.Offline quantitative flow ratio(QFR)analysis was performed on these cases.Patients were divided into two groups:LDL-C controlled group(LDL-C<1.8 mmol/L,148 patients with 191 vessels)and LDL-C uncontrolled group(LDL-C≥1.8 mmol/L,71 patients with 98 vessels).Coronary artery QFR and anatomical indicators such as minimal lumen diameter,minimal lumen area,percentage diameter stenosis,percentage area stenosis were compared within and between the groups.Further analysis was performed to identify influencing factors leading to changes in coronary physiological parameters derived from QFR. Results:Within the LDL-C controlled group,there was no significant difference in the QFR values of the vessels compared to baseline(P>0.05),whereas in the LDL-C uncontrolled group(P<0.05),a notable decline in QFR was observed.Patients in the LDL-C controlled group had lower rates of maximum diameter and area stenosis and higher minimum lumen diameter and area(all P<0.05).Through multifactorial Logistic regression analysis,it was found that a body mass index＞28 kg/m2,LDL-C≥1.8 mmol/L,and a history of myocardial infarction were independent risk factors leading to the decline in QFR(all P<0.05). Conclusions:It was found that patients in the LDL-C controlled group had higher coronary artery QFR,minimum lumen diameter and area,lower rates of maximum diameter and area stenosis.

Objective:To compare the mid-term clinical effects of AngioJet rheolytic thrombectomy assisted catheter-directed thrombolysis (ART+CDT) with catheter-directed thrombolysis (CDT) in the treatment of acute deep venous thrombosis of lower extremities.Methods:Ninety-one patients admitted to the Department from Jan 2016 to Dec 2017 were placed with inferior vena cava filters and divided into ART+CDT group (30 cases)and CDT group (61 cases). Total urokinase dosge, thrombolytic time, operative cost, length of hospital stay, detumescence rate, thrombus clearance rate, cumulative patency rate of lower limb veins, Villalta score at 2 years and 5 years, thrombosis recurrence rate and chronic venous insufficiency quality of life questionnaire were compared between the two groups.Results:The success rate of surgery was 100% in both groups, there was no mortality. There were significant differences in the short-term postoperative outcomes between the two groups in terms of total dosage of urokinase, thrombolysis time, total cost of surgery, length of hospital stay, detumescence rate, venous patency scores before and after treatment, and venous patency rate (all P<0.05). For the mid- and long-term postoperative outcomes of 2 and 5 years, there were no significant differences in the incidence of PTS, recurrence rate of thrombus, chronic venous function scale, and cumulative patency rate at 2 years (all P>0.05). Conclusions:ART+CDT has a significant advantage over CDT alone in terms of early efficacy and early reopening of blood flow in patients. Both ART+CDT and CDT have a low incidence of PTS and a low recurrence rate of thrombus in the mid-term follow-up, and both have satisfactory performance in the mid- and long-term efficacy of interventional treatment of deep venous thrombosis of lower limbs.

Objectives:To investigate the relationship between total ischemic time(TIT)and the risk of major adverse cardiovascular events(MACE,including all-cause death,non-fatal myocardial infarction,non-fatal ischemic stroke)within 1 year after primary percutaneous coronary intervention(PPCI)in patients with ST segment elevation myocardial infarction(STEMI)with TIT≤720 minutes. Methods:A total of 1 812 STEMI patients who underwent PPCI and had a TIT≤720 minutes in the Chest Pain Center of the General Hospital of the Southern Theatre Command of PLA from January 1,2011 to December 31,2021 were selected as the research subjects.Logistic regression and Cox regression models were used to analyze the association between TIT and the risk of MACE in the hospital and within 1 year after discharge.The restricted cubic spline(RCS)analysis was used to analyze the dose-response relationship between TIT and the risk of MACE. Results:Among 1 812 patients,the incidence of MACE during hospitalization was 3.26%,and the incidence of MACE within 1 year after discharge was 6.84%in 1 651 patients who survived.RCS analysis showed that TIT had an approximate logarithmic linear relationship with the risk of MACE during hospitalization and within 1 year after discharge,and the risk of MACE increased with longer TIT.Multivariate logistic regression analysis showed that compared with the group with a TIT of≤480 minutes,the risk of MACE during hospitalization increased by 77.7%(OR=1.777,95%CI:1.020-2.929,P=0.038)in the group with a TIT of more than 480 minutes.Multivariate Cox proportional hazards regression analysis showed that compared with the group with a TIT of≤280 minutes,the risk of MACE within 1 year after discharge increased by 106.7%(HR=2.067,95%CI:1.384-3.089,P<0.001)in the group with a TIT of more than 280 minutes. Conclusions:In STEMI patients after PPCI,the risk of MACE during hospitalization significantly increases when TIT exceeds 480 minutes,and the risk of MACE within 1 year after discharge significantly increases when TIT exceeds 280 minutes.

Objective:To investigate the treatment and prognosis of acute carotid artery occlusion during perioperative period of carotid endarterectomy (CEA).Methods:The clinical data of 112 carotid artery stenosis patients who underwent CEA from January 2017 to December 2021 in Lianyungang Hospital Affiliated to Xuzhou Medical University were retrospectively analyzed. The patients were followed up at 6 to 9 months after surgery, the clinical prognosis was evaluated by Glasgow outcome score (GOS), and the head and neck CT angiography (CTA) was performed.Results:Among the 112 patients, 5 patients underwent acute carotid artery occlusion during the perioperative period, including 1 case of intraoperative acute occlusion of internal carotid artery and 1 case of intraoperative internal carotid artery combined with external carotid artery cute occlusion, both of them were re-sutured, and multi-mode monitoring showed that each carotid artery was unobstructed; 2 cases of intraoperative external carotid artery occlusion, no re-suture was performed during the operation; 1 case of intraoperative monitoring showed no obvious abnormality, and the contralateral limb hemiplegia was observed after surgery, and the muscle strength was grade 1, the carotid color Doppler ultrasound showed the occlusion of the internal carotid artery on the operation side. The CT and CTA examination showed focal infarction and common carotid artery on the operation side, and drugs and conservative treatment were given. The follow-up result: GOS 5 scores was in 4 cases, and 4 scores in 1 case; the muscle strength of hemiplegia patient recovered to grade 4; head and neck CTA examination, except for 1 case of common arterial occlusion, the other 4 cases showed no special abnormality.Conclusions:Intraoperative acute carotid artery occlusion can be detected timely by intraoperative multi-mode hemodynamic monitoring during CEA. Vascular recanalization after acute occlusion is possible by adopting active and effective treatment methods, the occurrence of postoperative ischemic stroke can be effectively prevented and the prognosis of patients can be improved.
