Objective To explore the predictive value of lipoprotein(a) (Lp[a]) levels for major adverse cardiovascular events (MACE) in patients with acute coronary syndrome (ACS). Methods A total of 310 ACS patients who were hospitalized in Dalian Friendship Hospital and completed coronary angiography from August 2021 to October 2023 were included in this study. According to the level of Lp(a), the patients were divided into high Lp(a) group (＞300 mg/L, n=224) and low Lp(a) group (≤300 mg/L, n=86). All patients undergo outpatient follow-up after discharge, the occurrence of major MACE was recorded, and multivariate Cox regression analysis was performed to analyze the influencing factors of MACE in ACS patients. Results The age, C-reactive protein, total cholesterol, ApoB, proportion of multiple lesions and percutaneous coronary intervention (PCI), Gensini score of the high Lp(a) group were higher than those of the low Lp(a) group, while uric acid and LVEF were lower than those of the low Lp(a) group (all P<0.05). The median follow-up time for all ACS patients was 22 (17, 24) months, with a total of 61 patients (19.68%) experiencing MACE. The high Lp(a) group had a higher readmission rate and cumulative MACE incidence for angina compared to the low Lp(a) group (P=0.009, P=0.001). Single factor analysis showed that high Lp(a) level, diabetes, myocardial infarction, left main artery disease, multi vessel disease, PCI, age, Gensini score, LVEF, and homocysteine were significantly correlated with MACE (all P<0.05). After adjusting for multiple factors, the MACE risk in the high Lp(a) group was 3.42 times higher than that in the low Lp(a) group (HR=3.42, P=0.016). Conclusion Lp(a)＞300 mg/L is an independent risk factor for the development of MACE in patients with ACS, and can be used as a predictor for the development of MACE in patients with ACS.

Objective To explore the new mechanism of Escin inhibiting the progression of breast cancer cells.Methods Escin treatment groups with different concentrations(0,10,20,30,40μg/ml)were set up,and BC cells were treated with corresponding concentrations of Escin,then CCK8,clonal formation,flow cytometry,transmission electron microscopy and protein immunoblotting were used to evaluate the cell phenotype and possible mechanisms.Control group,Escin group and Escin+VX-765 group were set up,to determine the role of Caspase-1/GSDMD signaling pathway in Escin-induced pyroptosis of BC cells,cells were pretreated with Caspase-1 inhibitor VX-765.The cells in control group,Escin group and Escin+NAC group were pretreated with the reactive oxygen species(ROS)scavher N-Acetylcysteine(NAC),to determine the role of ROS in Escin induced pyroptosis of BC cells.Results Compared with the control group,different concentrations of Escin inhibited the proliferation and colony formation of BC cells in a concentration dependent manner(P＜0.05).Compared with the control group,the ROS and pyroptosis rate were increased in Escin-treated group(P＜0.05).The protein expression levels of FL-GSDMD and pro-Caspase-1 were significantly decreased in the Escin-treated group,while N-GSDMD,cleaved Caspase-1 and IL-18 protein expression were significantly increased(P＜0.05).Compared with the Escin-treated group,the proliferation rate of Escin+VX-765 group was increased(P＜0.05),and the expression of pyroptosis protein was decreased(P＜0.05).Compared with the Escin-treated group,the proliferation rate of Escin+NAC group was increased(P＜0.05),and the ROS,pyroptosis rate and pyroptosis protein expression were decreased(P＜0.05).Conclusion The inhibitory effect of Escin on the progression of breast cancer cells may be related to its regulation of ROS/Caspase-1/GSDMD signaling pathway to promote cell pyroptosis.

Objective To explore the causal relationships of anxiety,depression and neuroticism with recurrent spontaneous abortion(RSA).Methods Genome-wide association study(GWAS)data were used to extract single nucleotide polymorphisms(SNPs)closely related to anxiety,depression and neuroticism as instrumental variables(IVs).Inverse variance weighting(IVW),weighted median estimator(WME),weighted mode(WM)and Mendelian randomization(MR)-Egger regression were employed for MR analysis to evaluate the causal effects of anxiety,depression and neuroticism with RSA,and to analyze heterogeneity,gene pleiotropy and sensitivity.Results A total of 46 SNPs were extracted from GWAS data as IVs(5 anxiety SNPs,9 depression SNPs,and 32 neuroticism SNPs).IVW,WME,WM and MR-Egger regression analysis revealed that the odds ratio(OR)and 95%confidence interval(CI)of anxiety data were 1.07(0.86-1.32),1.10(0.85-1.43),1.14(0.81-1.59)and 1.18(0.53-2.61);those of depression data were 1.11(0.93-1.32),1.05(0.83-1.32),0.96(0.67-1.38)and 0.57(0.25-1.31);those of neuroticism data were 1.01(0.75-1.36),1.07(0.73-1.56),1.02(0.49-2.12)and 2.40(0.46-12.44),but none of the above causal analyses were statistically significant(all P>0.05).After reliability analysis,the Cochran's Q test for heterogeneity evaluation was not significant(P>0.05),the MR-Egger regression intercepts for gene pleiotropy evaluation were all close to 0(P>0.05),and the sensitivity evaluation"Leave-one-out"test also shows that the combined causal effect values are similar.Conclusion There dose not exist causal relationships of anxiety,depression and neuroticism with RSA.The reliability test shows that the results are relatively robust.

Objective:To evaluate the effect of fiberoptic endoscopic evaluation of swallowing (FEES) on clinical functional outcomes of patients with intensive care unit-acquired swallowing disorders (ICU-ASD).Methods:This retrospective cohort study analyzed clinical data of patients diagnosed with post-extubation dysphagia (PED) in the intensive care unit (ICU) and respiratory intensive care unit (RICU) of the Affiliated Hospital of Inner Mongolia Medical University from February 2020 to February 2025. Patients were categorized into a FEES group of 60 cases [34 males, 26 females, aged 37-80 years (median age 62 years)] and a control group without FEES of 58 cases [32 males, 26 females, aged 39-77 years (median age 61 years)].The patients in two groups received swallowing function and feeding training based on the results of the FEES assessment and the Volume-Viscosity Swallow Test-Clinical Version (VVST-CV), respectively. Clinical functional outcome measures included pneumonia incidence, clinical pulmonary infection score (CPIS), pneumonia severity index (PSI), Functional Oral Intake Scale (FOIS), and dietary method at discharge. χ2 test, Mann-Whitney U test, and Wilcoxon signed-rank test, were employed for statistical analysis of the outcome measures. Results:Compared with the control group, the FEES group had significantly lower aspiration pneumonia incidence at discharge [3.3% (2/60) vs 15.5% (9/58), χ2=5.179, P=0.023]. Regarding dietary methods,a significantly higher proportion of patients in the FEES group achieved complete oral feeding compared with the control group [75.0% (45/60) vs 67.3% (39/58), χ2=8.065, P<0.05]. After training, the FEES group had higher median FOIS scores than the control group (7.00 vs 6.00, Z=-2.370, P=0.018), and lower CPIS scores (2.50 vs 5.00, Z=-2.216, P=0.027) and PSI scores (59.00 vs 73.00, Z=-2.251, P=0.024). Within-group comparisons revealed that FOIS scores significantly improved post-training in both groups (both P<0.001). Conclusion:Early FEES examination for ICU patients with acquired swallowing disorders is associated with a lower incidence of pneumonia, improved swallowing function, and superior clinical functional outcomes.

Myocardial ischemia-reperfusion injury(MIRI)is a common cardiac pathological process,resulting from the combined effects of multiple mechanisms involving metabolic changes and mitochondrial dysfunction.Mitochondrial quality control(MQC),as a key regulatory mechanism,may serve as an important target for the prevention and treatment of MIRI.In recent years,traditional Chinese medicine(TCM)has demonstrated unique advantages in the field of improving MIRI,with multiple targets,multiple pathways,and low toxic and side effects.It has gained widespread clinical recognition and application.Through systematically organizing and summarizing recent studies on the targeting of MQC by monomers,active fractions,herb pairs,compound formulas and related preparations of TCM to improve MIRI,this paper finds that monomers and active fractions of TCM(such as schisandrin B,isoliquiritigenin,calenduloside E,berberine,Lycium barbarum polysaccharides and so on)as well as TCM herb pairs,compound formulas,and related preparations(couplet medicinals of Fuzi-Ganjiang,Yixin formula,Shuangshen ningxin capsule,Baijin formula,Yiqi huoxue decoction and so on),can alleviate MIRI by activating MQC to reduce oxidative stress-induced damage,promote mitochondrial biogenesis,maintain mitochondrial fission/fusion homeostasis,regulate mitochondrial autophagy,and restore mitochondrial calcium homeostasis.

Objective    To retrospectively analyze the surgical treatment of Stanford type A aortic dissection after coronary artery stenting, and to explore the surgical techniques and surgical indications. Methods    Clinical data of 1 246 consecutive patients who underwent operations on Stanford type A aortic dissection from April 2016 to July 2019 in Beijing Anzhen Hospital were retrospectively analyzed. Patients with Stanford type A aortic dissection after coronary artery stenting were enrolled. Results    Finally 19 patients were collected, including 16 males and 3 females with an average age of 54±7 years ranging from 35 to 66 years. There were 11 patients in acute phase, 15 patients with AC (DeBakey Ⅰ) type and 4 patients with AS (DeBakey Ⅱ) type. In AC type, there were 10 patients receiving Sun's surgery and 5 patients partial arch replacement. Meanwhile, coronary artery bypass grafting was performed in 7 patients and mitral valve replacement in 1 patient. Stents were removed from the right coronary artery in 4 patients. In this group, 1 patient died of multiple organ failure in hospital after operation combined with malperfusion of viscera. Eighteen patients recovered after treatment and were discharged from hospital. The patients were followed up for 30 (18-56) months. One patient underwent aortic pseudoaneurysm resection, one thoracic endovascular aortic repair, one emergency percutaneous coronary intervention due to left main artery stent occlusion, and one underwent femoral artery bypass due to iliac artery occlusion. Conclusion    Iatrogenic aortic dissection has a high probability of coronary artery bypass grafting at the same time in patients with Stanford type A aortic dissection after coronary artery stenting. Complicated type A aortic dissection after percutaneous coronary intervention should be treated with surgery aggressively.

Objective:To investigate the level of functional fitness of elderly hypertensive patients in the community and to analyze its influencing factors.Methods:A cross-sectional survey was used from November 2021 to September 2022, questionnaire survey and Senior Functional Fitness Test (SFT) were conducted on 189 elderly hypertensive patients in the community by convenience sampling method, multiple linear regression was used to analyze the influencing factors of SFT in elderly hypertensive patients in the community.Results:Totally 189 cases of community-aged hypertensive patients completed the investigation, 88 cases were male and 101 were female. The total SFT score of community-aged hypertensive patients was (58.61 ± 16.07). Single factor analysis showed that there were significant differences in SFT scores among patients with different gender, age and education ( t=-2.57, F=6.24, 7.54, all P<0.05). Multifactorial analysis revealed that age ( t=-5.55), gender ( t=2.63), and literacy ( t=5.69) were influential factors in the total SFT scores of community-dwelling elderly hypertensive patients (all P<0.05). Conclusions:Age, gender, and literacy level are the main factors affecting the total SFT scores of elderly hypertensive patients in the community, and community caregivers should pay close attention to the above elderly hypertensive population.
