OBJECTIVES To establish a scoring system combining the ACEF score and the quantitative blood flow ratio(QFR) to improve the long-term risk prediction of patients undergoing percutaneous coronary intervention(PCI).METHODS In this population-based cohort study, a total of 46 features, including patient clinical and coronary lesion characteristics, were assessed for analysis through machine learning models. The ACEF-QFR scoring system was developed using 1263consecutive cases of CAD patients after PCI in PANDA Ⅲ trial database. The newly developed score was then validated on the other remaining 542 patients in the *** In both the Random Forest Model and the Deep Surv Model, age, renal function(creatinine), cardiac function(LVEF)and post-PCI coronary physiological index(QFR) were identified and confirmed to be significant predictive factors for 2-year adverse cardiac events. The ACEF-QFR score was constructed based on the developmental dataset and computed as age(years)/EF(%) + 1(if creatinine ≥ 2.0 mg/d L) + 1(if post-PCI QFR ≤ 0.92). The performance of the ACEF-QFR scoring system was preliminarily evaluated in the developmental dataset, and then further explored in the validation dataset. The ACEF-QFR score showed superior discrimination(C-statistic = 0.651;95% CI: 0.611-0.691, P < 0.05 versus post-PCI physiological index and other commonly used risk scores) and excellent calibration(Hosmer–Lemeshow χ^(2)= 7.070;P = 0.529) for predicting 2-year patient-oriented composite endpoint(POCE). The good prognostic value of the ACEF-QFR score was further validated by multivariable Cox regression and Kaplan–Meier analysis(adjusted HR = 1.89;95% CI: 1.18–3.04;log-rank P < 0.01) after stratified the patients into high-risk group and low-risk *** An improved scoring system combining clinical and coronary lesion-based functional variables(ACEF-QFR)was developed, and its ability for prognostic prediction in patients with PCI was further validated to be signi

iTRAQ-based Quantitative Proteomic Profiling of the Regulatory Mechanisms on Immune Functions and Blood Lipids in Aged Mice Fed with Lentinula edodes-Derived Polysaccharides

Food Science and Human Wellness 2024年

作者： Xiaofei xu Xiaofei Liu Jin Chen Jingjing guan Donghui Luo College of Food Science and Engineering， guangdong Ocean University

The mechanisms of mushroom polysaccharides on immune functions and lipid metabolism of aged mammals have not been fully elucidated. In the present study， after assessing the impacts of one type of Lentinula edodes-derived polysaccharides， named L2， on immune functions and blood lipid profiles， isobaric tags for relative and absolute quantification (iTRAQ)-based proteomic profiling of the small intestinal tissues from aged mice treated with L2 was performed. L2 reversed immune function declines and modulated the lipid metabolism of aged mice evidenced by increased levels of serum TC， HDL-C， and LDL-C， and reduced levels of serum TG. Moreover， a total of 95 differentially regulated proteins (DRPs) were identified， of which 75 were up-regulated and 20 were down-regulated. Most of the DRPs were involved in intracellular and extracellular structure organization， and cellular and metabolic regulation. Particularly， approximately 16 and 9 DRPs participated in the regulation of immune functions and lipid metabolism， respectively. Furthermore， protein-protein interaction analysis highlighted that cadherin 1， plectin， cadherin-17， Ras GTPase-activating-like protein IQGAP2， and ezrin might be key proteins in response to L2 treatment. These findings provide new insights into the biological mechanisms of mushroom polysaccharides in anti-aging from a proteomic perspective.

本文利用1983年1月至1986年12月的全球Lageos卫星激光测距(SLR)资料求得了类阻力系数C_D的一个序列C_(D1),对此序列应用AR谱估计的Marple算法进行谱分析,其呈现的主要周期为475.5天,周年项365.2天,216.4天和半年项183.4天.此外还有69天,39.9天,32.25天的周期.我们又利用多级复弧法求得的类阻力系数C_D的另一序列C_(D2)作同样的谱分析,得出C_(D2)序列的主要周期有173.3天,152.8天,127.6天,61.3天,27.64天.经过比较分析,我们认为C_(D1)序列中出现的475.5天,365.2天,183.4天的周期,实际上是BIH系统和SLR技术所解得的ERP序列在极移x_p分量上存在的系统差的一种反映.
