Long-term hypertension causes excessive vascular remodeling and leads to adverse cardiovascular events. Balance of ubiquitination and deubiquitination has been linked to several chronic conditions, including pathological vascular remodeling. In this study, we discovered that the expression of ubiquitin-specific protease 25 (USP25) is significantly up-regulated in angiotensin II (Ang II)-challenged mouse aorta. Knockout of Usp25 augments Ang II-induced vascular injury such as fibrosis and endothelial to mesenchymal transition (EndMT). Mechanistically, we found that USP25 interacts directly with Forkhead box O3 (FOXO3) and removes the K63-linked ubiquitin chain on the K258 site of FOXO3. We also showed that this USP25-mediated deubiquitination of FOXO3 increases its binding to light chain 3 beta isoform and autophagosomic-lysosomal degradation of FOXO3. In addition, we further validated the biological function of USP25 by overexpressing USP25 in the mouse aorta with AAV9 vectors. Our studies identified FOXO3 as a new substrate of USP25 and showed that USP25 may be a potential therapeutic target for excessive vascular remodeling-associated diseases.

Objective:To analyze the diagnostic value of inflammatory markers, clinical characteristics of patients with different prognoses, and variations in antimicrobial susceptibility testing for Klebsiella pneumoniae bloodstream infection. Methods:This study involved 166 patients with positive blood cultures for Klebsiella pneumoniae from January 2018 to May 2023 as the Klebsiella pneumoniae-positive group, and 100 patients with negative blood culture results as the negative group. The diagnostic value of inflammatory markers for Klebsiella pneumoniae bloodstream infection was evaluated through receiver operating characteristic (ROC) curve. The differences in C-reactive protein (CRP) and procalcitonin (PCT) levels between Klebsiella pneumoniae bloodstream infections and non- Klebsiella pneumoniae bloodstream infections were analyzed. According to the prognoses, 166 patients with Klebsiella pneumoniae bloodstream infection were divided into two groups: favorable outcome group (105 cases) and adverse outcome group (61 cases). Clinical features, infection sites, empirical use of antibiotics, and antimicrobial susceptibility were compared between the patients with different outcomes. Results:The percentage of neutrophils ( Z=-3.645, P<0.001), CRP level ( Z=-6.809, P<0.001), and PCT level ( Z=-8.214, P<0.001) were significantly higher in the Klebsiella pneumoniae-positive group than in the negative group. The area under the ROC curve (AUC) values for CRP and PCT in diagnosing Klebsiella pneumoniae bloodstream infection were 0.755 and 0.849, respectively. There were variations in CRP ( H=20.902, P<0.001) and PCT ( H=33.521, P<0.001) levels among patients with bloodstream infection caused by Klebsiella pneumoniae, other common negative bacilli, common positive cocci, or Candida. The body temperature, albumin level, hemoglobin level, and length of hospital stay in the adverse outcome group were lower than those in the favorable outcome group ( P<0.05). Besides, the incidence of invasive operation, organ failure, shock, and rescue were also lower in the adverse outcome group ( P<0.05). In the adverse outcome group, co-infections mainly involved respiratory infections, accounting for 60.7% (37/61). Respiratory infections (49.5%, 52/105) were also the predominant co-infections in the favorable outcome group, followed by hepatobiliary infections (34.3%, 36/105). The pathogenic bacteria cultured from different infection sites were mainly Klebsiella pneumoniae. In the favorable outcome group, fluoroquinolones were the most commonly used medications for empirical therapy, with a usage rate of 76.2% (80/105), followed by β-lactamase inhibitor complex preparations (68.6%, 72/105), the usage rate of which were significantly higher than those in the adverse outcome group ( P<0.05). Carbapenems were the preferred drugs for the adverse outcome group, with a usage rate of up to 62.3% (38/61), which was significantly higher than that in the favorable outcome group ( P<0.05). The adverse outcome group showed high resistance rates to ciprofloxacin (40.98%, 25/61) and levofloxacin (37.7%, 23/61), while the resistance rates were 22.86% (24/105) and 32.38% (34/105) in the favorable outcome group. The resistance rates to other drugs were low and there was no significant difference between the two groups ( P>0.05). Conclusions:PCT and CRP have certain value in diagnosing bloodstream infections caused by Klebsiella pneumoniae, and have certain reference significance for differentiating bloodstream infections caused by Gram-negative bacteria, Gram-positive bacteria, and Candida species. The source of bloodstream infection in patients with adverse outcome may be the respiratory system, while in patients with favorable outcome, the main sources of bloodstream infection may be the respiratory and hepatobiliary systems. Antimicrobial susceptibility testing reveals the highest resistance rate to fluoroquinolones. Given their frequent use in empirical therapy, this may lead to treatment failure. Notably, carbapenems are more commonly administered as empirical antibiotics in the adverse outcome group.

Objective To investigate the incidence and predictors of cerebral infarction in patients with ruptured ACoA aneurysms, and to provide diagnostic and therapeutic information.Methods A total of 319 patients with ruptured ACoA aneurysms in our hospital from January 2009 to February 2015 were reviewed in this study. The author collected data regarding clinical characteristics, and measured the aneurysm morphologies on CTA images. Age, flow angle, vessel angle were analyzed by independent-samples t tests in patients with or without cerebral infarction. Mann-Whitney U tests were used for aneurysm size, aneurysm height, perpendicular height, neck size, size ratio, aspect ratio, aneurysm angle , World Federation of Neurosurgical Societies (WFNS) grade at admission and Fisher grade. Chi-square tests and Fisher's exact tests were used for sex, histories of hypertension, smoking and stroke, treatment modalities, anterior cerebral A1 segment configuration and angiographic vasospasm on CTA images. The multivariate logistic regression analyses were used to determine the independent risk factors of cerebral infarction using the stepwise regression method. Results Of the 319 patients, there were 253 without and 66 patients with cerebral infarction. Differences of age(53±11 vs 57±12,respectively;t=-2.415, P=0.016), Fisher grade [Ⅰ 23(9.1%), Ⅱ 27(10.7%), Ⅲ 74(29.2%), Ⅳ 129(51.0%) vs Ⅰ 1(1.5%), Ⅱ 7 (10.6% ), Ⅲ 13(19.7% ), Ⅳ 45(68.2% ), respectively;Z=-2.541, P=0.035] and treatment modalities [endovascular coil embolization 155(61.3% ), neurosurgical clipping 98(38.7% ) vs endovascular coil embolization 23(34.8%), neurosurgical clipping 43(65.2%), respectively;χ2=14.810, P<0.001] reached statistical significance. Multivariate analysis showed that Fisher grade Ⅳ(OR=10.36,95%CI 1.34-80.29, P=0.025) and neurosurgical clipping (OR=3.28, 95% CI 1.84-5.86,P<0.001)still had statistical significance. Conclusions Cerebral infarction in patients with ruptured ACoA aneurysms may be associated with Fisher grade and treatment modalities. Although there is difference between the two groups in age, it is not a predictor of the occurrence of cerebral infarction.
