OBJECTIVE To compare the efficacy and safety of evolocumab and probucol in patients with ultra-high-risk atherosclerotic cardiovascular disease （ASCVD） following percutaneous coronary intervention （PCI）. METHODS A retrospective analysis was conducted on 156 ultra-high-risk ASCVD patients who underwent PCI in our institution between January 1， 2023 and December 31， 2024. According to the lipid-lowering regimen， the patients were categorized into evolocumab group （ n ＝86） and probucol group （ n ＝70）. Changes in lipid parameters [total cholesterol （TC）， low-density lipoprot ein cholesterol （LDL-C）， high-density lipoprotein cholesterol （HDL-C）， triglycerides， lipoprotein （a）， and lipid goal achievement rate ] ， inflammatory markers [interleukin-6 （IL-6） and C-reactive protein （CRP） ] ， and cardiac function indices （left ventricular ejection fraction， left ventricular end-systolic diameter， left ventricular end-diastolic diameter， and N-terminal pro-B-type natriuretic peptide） were compared between two groups at baseline and after 6 months of treatment. The incidence of adverse clinical events during treatment， including acute myocardial infarction， in-stent restenosis， acute heart failure， cerebral hemorrhage， and stroke， was also evaluated. RESULTS No statistically significant differences were observed between the two groups at baseline （ P ＞0.05）. After 6 months of treatment， both groups demonstrated significant improvements in lipid profiles （except HDL-C） and inflammatory markers compared to those at baseline （ P ＜0.05）. The evolocumab group exhibited greater reductions in TC， LDL-C， IL-6， and CRP， along with a higher lipid target achievement rate， compared with the probucol group （ P ＜0.05）. There were no statistically significant differences in the cardiac function-related indicators before and after treatment between the two groups， nor in the incidence of adverse events during the treatment （ P ＞0.05）. CONCLUSIONS For ultra-high-risk ASCVD patients after PCI， both of the above treatment options are associated with improvements in blood lipid and inflammatory response， with good safety during short-term follow-up. Evolocumab shows superior efficacy in TC， LDL-C and inflammatory markers reduction and lipid target achievement， compared to probucol.

OBJECTIVE To investigate the effects of galangin on rheumatoid arthritis （RA） in rats by regulating the Janus kinase 3 （JAK3）/signal transducer and activator of transcription 3 （STAT3） pathway. METHODS Fifty male SD rats were taken， and an emulsion composed of bovine type Ⅱ collagen and Freund’s complete adjuvant was injected subcutaneously to establish an induced arthritis model. The rats that were successfully modeled were randomly divided into model group， low， medium and high dose groups of galangin （1， 5， 15 mg/kg）， and methotrexate group （positive control， 2 mg/kg）， with 10 rats in each group. Another 10 normal rats were taken as the normal group. Starting from the 15th day of modeling， each group of rats was gavaged with the corresponding drug solution or normal saline containing 0.5% Tween 80 once a day for 28 consecutive days. The arthritis index （AI） scores and paw volume of rats were compared before and after gavage administration. Twenty-four hours after the last administration， the serum levels of interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， IL-4 and IL-10 were determined， the pathological changes in ankle joint synovial tissue were observed， and the protein expressions of UNC-51 like kinase 1 （ULK1）， Beclin-1， microtubule-associated protein 1 light chain 3 （LC3）， B cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， caspase-3， JAK3， phosphorylated JAK3 （p-JAK3）， STAT3 and phosphorylated STAT3 （p-STAT3） in the synovial tissue of the ankle joint were detected， as well as the fluorescence intensity of LC3-positive areas. RESULTS Compared with the model group， the pathological changes such as cellular proliferation of ankle joint synovial tissue and infiltration of inflammatory cells in rats of each administration group showed improvement. Moreover， their AI scores and paw pad volumes （on day 28 after gavage）， the levels of IL-6 and TNF-α， the protein expression of Bcl-2， and the phosphorylation levels of JAK3 and STAT3 were all significantly reduced （ P ＜0.05）. The levels of IL-4 and IL-10， the protein expressions of ULK1， Beclin-1， Bax， caspase-3 and LC3， as well as the fluorescence intensity of LC3-positive areas， were all significantly increased （ P ＜0.05）. Moreover， the effect of galangin was in a dose-dependent manner （ P ＜0.05）. CONCLUSIONS Galangin can induce sustained autophagy in synovial tissue cells of RA rats， promote cell apoptosis， inhibit synovial cell proliferation， and alleviate persistent inflammatory responses. The above anti-RA effects may be related to the inhibition of the JAK3/STAT3 pathway.

Objective:To construct a frailty risk prediction model for elderly patients with CHD based on machine learning, to address the limitations of existing tools and provide evidence-based support for clinical practice.Methods:A retrospective study was conducted on elderly CHD patients hospitalized at the Heart Center of the First Affiliated Hospital of Henan University of Chinese Medicine from September 2023 to March 2024. Meta-analysis and expert meetings were used to identify the risk factors for frailty in elderly CHD patients. Three machine learning algorithms, Logistic Regression, Random Forest, and Support Vector Machine, were used to construct predictive models using R 4.3.1 software. The predictive performance of the models was evaluated using sensitivity, specificity, accuracy, and the area under the receiver operating characteristic curve (AUC).Results:A total of 490 elderly CHD patients were included, with 267 males and 223 females, and an age of (71.02 ± 7.73) years. Among them, 160 patients (32.7%) developed frailty. Of the constructed models, the Random Forest model demonstrated the best predictive performance, with an accuracy of 0.703, recall of 0.629, and F1 score of 0.741, while the AUC was 0.811 (95% CI 0.762-0.850). Conclusions:The Random Forest model exhibited good predictive performance in assessing frailty risk in elderly CHD patients, with high accuracy and reliability. Future external validation studies can further assess its applicability and stability in different populations.

Objectives:To develop a risk prediction model for sudden cardiac arrest(CA)in children with congenital heart disease(CHD)after surgery and validate its predictive efficacy,providing a reference for the prevention of CA and risk stratification.Methods:Medical records were retrospectively analyzed from 5 029 children who were hospitalized in Fuwai Hospital,Chinese Academy of Medical Sciences from January 1,2020 to May 31,2022 and underwent CHD surgery.The patients were divided into two groups:those who experienced CA after surgery(n=33)and those who did not(n=4 996).A random forest model for predicting the risk of postoperative CA was established on the training dataset using R software,and the predictive effect of the model was evaluated on the validation dataset using indicators of predictive accuracy,sensitivity,specificity,positive predictive value,negative predictive value.Results:The incidence of CA in this center was 0.66%,survival rate is 72.73%.Using the random forest algorithm,the importance of risk factors for sudden CA after CHD surgery was ranked by variable importance scoring,with the following top 6 important predictive variables:blood pressure,lactate levels,heart rate,cardiac rhythm,arterial oxygen partial pressure,and blood oxygen saturation on the first day after surgery.The model established by the random forest algorithm on the training set was validated on the test set,yielding a predictive accuracy of 99.8%,specificity of 87.5%,sensitivity of 99.9%,kappa coefficient of 0.8225,positive predictive value of 99.9%,and negative predictive value of 77.8%.Conclusions:The established prediction model of sudden CA in children with CHD after surgery had good performance.It might help medical staffon decision making of early intervention,preventing the occurrence of CA,and improving the outcomes of children with high risk of CA post surgery.

Objective To investigate the expression level of centromere protein(CENP)Ⅰin lung adenocarcinoma cells,to study the effects of CENPⅠon the proliferation,invasion,migration,apoptosis,and epithelial-mesenchymal transition(EMT)of lung adenocarci-noma cells,and to explore the possible mechanisms related to its occurrence.Methods The expression of CENPⅠmRNA and protein in four types of lung adenocarcinoma cells and normal alveolar epithelial cells were detected by quantitative real-time polymerase chain reaction(RT-qPCR)and Western blotting.The expression of CENPⅠin H1650 cells was knocked down by the siRNA technique,The transfection efficiency was detected by RT-qPCR and Western blotting.The effects of knock-down CENPⅠon proliferation,cell cycle,apoptosis,invasion and migration of H1650 cells were detected by the cell counting kit-8 assay,the transwell assay,and flow cytometry.Western blotting was used to detect the expression of E-cadherin,N-cadherin,vimentin,Ki-67,cyclin D1,Bcl-2,PI3K,AKT,mTOR,p-PI3K,p-AKT,and p-mTOR.Results After the knock-down of CENPⅠ,the proliferative ability of the H1650 cells significantly decreased,the number of apoptotic cells significantly decreased,and the cell invasion and migration abilities significantly decreased(P<0.01).E-cadherin expression was upregulated and N-cadherin,vimentin,Ki-67,cyclin D1,Bcl-2,p-PI3K,p-AKT,and p-mTOR expres-sion were down-regulated in the CENTI group compared with the control group(P<0.05).The expression of p-PI3K,p-AKT,and p-mTOR in the si-CENPⅠ+IGF-1 group was upregulated compared to that in the si-CENPⅠgroup(P<0.05).Conclusion High expression of CENPⅠin lung adenocarcinoma cells promotes the proliferation,invasion,and migration of lung adenocarcinoma H1650 cells and EMT inhibits apoptosis,which may be related to the activation of the PI3K/AKT/mTOR signaling pathway.

Objective:To explore the clinical efficacy of three different surgical timings of modified cervical cerclage in twin pregnant women with cervical insufficiency.Methods:The clinical data of 73 twin pregnant women who underwent modified cervical cerclage and had pregnancy outcomes in Qilu Hospital of Shandong University (Qingdao) from April 2014 to July 2023 were retrospectively analyzed. According to the different timings of surgery, they were divided into prophylactic cerclage group, ultrasound-indicated cerclage group (further divided into cervical length (CL)≤15 mm and 15 mm10 mg/L was a risk factor for preterm birth before 34 weeks of gestation ( OR=5.230, 95% CI: 1.616-16.929; P=0.006). Conclusions:In twin pregnant women with cervical insufficiency, prophylactic cerclage has the same surgical effect as ultrasound-indicated cerclage, while both prophylactic cerclage and ultrasound-indicated cerclage could significantly improve maternal and fetal outcomes compared with emergency cerclage. Twin pregnancies with CL≤15 mm might benefit from cervical cerclage. Postoperative CRP>10 mg/L is an independent risk factor for preterm birth before 34 weeks of gestation.

Stiff person syndrome (SPS) is a rare neuro-immune disorder characterized by exaggerated startle responses and muscle spasms in response to minor stimuli. SPS is often misdiagnosed as panic disorder or agoraphobia. This paper reported a case of a patient with SPS presenting symptoms similar to panic attack. The patient had been misdiagnosed as dystonia, anxiety disorder and panic attack. The patient was finally correctly diagnosed through multiple disciplinary team discussions. This study integrates a comprehensive understanding of symptomatology and patient-reported experiences with targeted neurological evaluations and supplementary diagnostic tools to improve the accuracy of etiological diagnoses. This study aims to enhance the ability of psychiatrists to recognize somatic diseases presenting with psychiatric symptoms and to improve clinical diagnostic and treatment levels.

Objective:To investigate the predictive value of refeeding syndrome (RFS) and its influencing factors for 30-day intensive care unit (ICU) readmission in critically ill patients.Methods:A prospective cohort study was conducted. Critically ill patients admitted to the department of critical care medicine, department of respiratory and critical care medicine, and department of neurology at Tianjin Medical University General Hospital from January to April in 2025 were enrolled. Patients were assessed for RFS according to the American Society for Parenteral and Enteral Nutrition (ASPEN) criteria. General information within 24 hours of ICU admission was collected via the electronic medical record system. Treatment details and 30-day ICU readmission status were dynamically recorded. Participants were divided into readmission and non-readmission groups based on whether ICU readmission occurred within 30 days. Intergroup comparisons were performed to identify differences. Multivariate Logistic regression was used to analyze the relationship between RFS and its influencing factors with 30-day ICU readmission. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive performance of risk factors.Results:A total of 196 critically ill patients were enrolled, among whom 25 (12.76%) were readmitted to ICU within 30 days and 171 (87.24%) were not. Significant differences were observed in the readmission group compared with the non-readmission group, including significantly higher rates of nasogastric decompression, higher acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, a higher incidence of RFS, and a longer duration of nasogastric decompression. Multivariate Logistic regression analysis showed that RFS was an independent risk factor for 30-day ICU readmission [odds ratio ( OR) = 5.756, 95% confidence interval (95% CI) was 1.603-20.670, P = 0.007]. APACHEⅡ score showed a positive correlation trend with 30-day ICU readmission ( OR = 1.057, 95% CI was 0.991-1.127, P = 0.092). ROC curve analysis showed that the combined prediction model incorporating RFS and APACHEⅡ score had an area under the ROC curve (AUC) of 0.766 (95% CI was 0.668-0.864), with a sensitivity of 88.0% and a specificity of 62.0%, which was significantly superior to a single indicator (the AUC of RFS and APACHEⅡ score was 0.639 and 0.624, respectively). Conclusions:RFS significantly increases the risk of 30-day ICU readmission in critically ill patients. A combined model incorporating RFS and APACHEⅡ score demonstrates good predictive efficacy for 30-day ICU readmission in critically ill patients.

Objective: The impact of prophylactic salpingectomy on the prevention of epithelial ovarian cancer (EOC) remains unclear, particularly in Asian populations where data is lacking. In this systematic review and meta-analysis study, we sought to assess whether prophylactic salpingectomy could reduce the incidence of ovarian cancer in the general population of multiple ethnicities. Methods: A systematic review and meta-analysis were conducted using PubMed/MEDLINE, EMBASE, the Cochrane Library, and Web of Science to assess the effectiveness of salpingectomy, bilateral salpingectomy (BS), and unilateral salpingectomy (US) in reducing the risk of EOC and evaluating postoperative outcomes. Results: The final analyses included 6 eligible trials (5,747,056 patients), including 1 cohort study and 5 case-control studies. The analyses of these studies demonstrated that women who underwent salpingectomy had a significantly reduced risk of EOC compared to those who did not receive salpingectomy (odds ratio [OR]=0.63; 95% confidence interval [CI]=0.45–0.89; p=0.007). Five studies (5,746,469 patients) indicated a significant reduction in EOC risk among patients who underwent BS (OR=0.48; 95% CI=0.33–0.69; p<0.001).On the other hand, in the analysis of 4 studies (5,745,887 patients) that examined US, the association with EOC risk was not significant despite the protective trend (OR=0.82; 95% CI=0.64–1.06; p=0.12). Conclusion Our results indicate BS is an effective strategy for reducing the risk of sporadic EOC, but the results did not lead to the same conclusion for patients who underwent US. When a candidate or patient is undergoing a hysterectomy or has other benign diseases, prophylactic BS may be a safe surgical procedure that carries future benefits in terms of EOC risk.
