    Abstract: Sex disparities in acute large vessel occlusion (LVO) following endovascular treatment (EVT) have been recently reported. However, there is uncertainty about the effect of sex differences on functional outcomes after EVT, particularly in an Asian population. The present study aimed to compare the clinical and safety outcomes between men and women with anterior circulation LVO treated with EVT. Methods: We analyzed data from the ANGEL-ACT (Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke: a Prospective Multicenter Registry Study) Registry, which was conducted at 111 hospitals from 26 provinces in China between November 2017 and March 2019. Men and women with anterior circulation LVO treated with EVT were matched using propensity scores. After a 1:1 propensity score matching, we compared the clinical outcomes including 90-day ordinal modified Rankin Scale distribution (primary outcome), procedure duration, successful reperfusion, symptomatic intracranial hemorrhage, and mortality. Furthermore, we explored sex modification on the primary outcome in subgroup analysis. Results: Of 1321 patients, 483 (36.6%) were women and 838 (63.4%) were men. The mean age for women and men were 68 and 62 years old, respectively. Among 578 patients identified after matching, there were no sex differences (men versus women) in 90-day ordinal modified Rankin Scale distribution (median [interquartile range], 4 [1–5] versus 3 [1–5], P =0.464), successful reperfusion (86.5% versus 91.0%, P =0.089), symptomatic intracranial hemorrhage (6.5% versus 7.9%, P =0.512), and mortality within 90 days (17.7% versus 17.0%, P =0.826). However, men had a longer median procedure duration than women (86 [52–128] versus 72 [48–110] minutes, β=14.51, [95% CI, 4.19–24.84]; P =0.006). Subgroup analysis showed that in patients with National Institutes of Health Stroke Scale score 〈 15, women tended to have a better outcome than men, whereas there was no gender effect in those with National Institutes of Health Stroke Scale score ≥15 ( P for interaction=0.032). Conclusions: Overall, this matched-control study from the ANGEL-ACT study showed similar clinical outcomes between men and women with anterior circulation LVO treated with EVT. However, in the subgroup of patients presenting with lower stroke severity (ie, National Institutes of Health Stroke Scale score 〈 15), women tended to have a better outcome than men highlighting a potential sex disparity for further investigation.

    Abstract: In patients undergoing mechanical thrombectomy (MT), adjunctive antithrombotic might improve angiographic reperfusion, reduce the risk of distal emboli and reocclusion but possibly expose patients to a higher intracranial hemorrhage risk. This study evaluated the safety and efficacy of combined MT plus eptifibatide for acute ischemic stroke. Methods: This was a propensity-matched analysis of data from 2 prospective trials in Chinese populations: the ANGEL-ACT trial (Endovascular Treatment Key Technique and Emergency Workflow Improvement of Acute Ischemic Stroke) in 111 hospitals between November 2017 and March 2019, and the EPOCH trial (Eptifibatide in Endovascular Treatment of Acute Ischemic Stroke) in 15 hospitals between April 2019 and March 2020. The primary efficacy outcome was good outcome (modified Rankin Scale score 0–2) at 3 months. Secondary efficacy outcomes included the distribution of 3-month modified Rankin Scale scores and poor outcome (modified Rankin Scale score 5–6) and successful recanalization. The safety outcomes included any intracranial hemorrhage, symptomatic intracranial hemorrhage, and 3-month mortality. Mixed-effects logistic regression models were used to account for within-hospital clustering in adjusted analyses. Results: Eighty-one combination arm EPOCH subjects were matched with 81 ANGEL-ACT noneptifibatide patients. Compared with the no eptifibatide group, the eptifibatide group had significantly higher rates of successful recanalization (91.3% versus 81.5%; P =0.043) and 3-month good outcomes (53.1% versus 33.3%; P =0.016). No significant difference was found in the remaining outcome measures between the 2 groups. All outcome measures of propensity score matching were consistent with mixed-effects logistic regression models in the total population. Conclusions: This matched-control study demonstrated that MT combined with eptifibatide did not raise major safety concerns and showed a trend of better efficacy outcomes compared with MT alone. Overall, eptifibatide shows potential as a periprocedural adjunctive antithrombotic therapy when combined with MT. Further randomized controlled trials of MT plus eptifibatide should be prioritized.

    Abstract: A recent randomized controlled trial DIRECT-MT (Direct Intra-Arterial Thrombectomy to Revascularize AIS Patients With Large Vessel Occlusion Efficiently in Chinese Tertiary Hospitals) compared the safety and efficacy of mechanical thrombectomy (MT) versus combined intravenous thrombolysis (IVT) and MT for acute large vessel occlusion. The current study utilized a prospective, nationwide registry to validate the results of the DIRECT-MT trial in a real-world practice setting. Methods: Subjects were selected from a prospective cohort of acute large vessel occlusion patients undergoing endovascular treatment at 111 hospitals from 26 provinces in China (ANGEL-ACT registry [Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke]) between November 2017 and March 2019. All patients eligible for IVT and receiving MT were reviewed and then grouped according to whether prior IVT or not (MT and combined IVT+MT). After a 1:1 propensity score matching, the outcome measures including the 90-day modified Rankin Scale, successful recanalization, door-to-puncture time, symptomatic intracranial hemorrhage, and intraprocedural embolization were compared. Results: A total of 1026 patients, 600 in the MT group and 426 in the combined group, were included. Among 788 patients identified after matching, there were no significant differences in the 90-day modified Rankin Scale (median, 3 versus 3 points; P =0.82) and successful recanalization (86.6% versus 89.3%; P =0.23) between the two groups; however, patients of the MT group had a shorter door-to-puncture time (median, 112 versus 136 minutes; β=−45.02 [95% CI, −68.31 to −21.74]), lower rates of symptomatic intracranial hemorrhage (5.5% versus 10.1%; odds ratio, 0.52 [95% CI, 0.30–0.91] ), and embolization (4.6% versus 8.1%; odds ratio, 0.54 [95% CI, 0.30–0.98]) than those of the combined group. Conclusions: This matched-control study largely confirmed the findings of the DIRECT-MT trial in a real-world practice setting, suggesting that MT may carry similar effectiveness to combined IVT+MT for acute large vessel occlusion patients, despite MT alone seems to be associated with a shorter in-hospital delay until procedure, lower risks of symptomatic intracranial hemorrhage, and embolization.

    Abstract: The role of stroke etiology subtype in patients with acute large vessel occlusion on the occurrence of hemorrhagic transformation (HT) after endovascular treatment is poorly studied, and which factors mediate their relationship remains largely unknown. We utilized nationwide registry data to explore the association of stroke subtype (cardioembolism versus large artery atherosclerosis) with HT and to identify the possible mediators. Methods: A total of 1015 subjects were selected from the ANGEL-ACT registry (Endovascular Treatment Key Technique and Emergency Work Flow Improvement of Acute Ischemic Stroke)—a prospective consecutive cohort of acute large vessel occlusion patients undergoing endovascular treatment at 111 hospitals in China between November 2017 and March 2019—and divided into large artery atherosclerosis (n=538) and cardioembolism (n=477) according to the Trial of ORG 10172 in Acute Stroke Treatment criteria. The types of HT included any intracerebral hemorrhage (ICH), parenchymal hematoma, and symptomatic ICH within 24 hours after endovascular treatment. The association between stroke subtype and HT was analyzed using a logistic regression model. Mediation analysis was done to assess how much of the effect of stroke subtype on HT was mediated through the identified mediators. Results: Stroke subtype (cardioembolism versus large artery atherosclerosis) was associated with increased risk of any ICH (29.8% versus 16.5%; odds ratio, 2.03 [95% CI, 1.22–3.36]), parenchymal hematoma (14.3% versus 5.4%; odds ratio, 2.90 [95% CI, 1.38–6.13] ), and symptomatic ICH (9.9% versus 4.7%; odds ratio, 2.59 [95% CI, 1.09–6.16]) after adjustment for potential confounders. The more thrombectomy passes in cardioembolism patients had a significant mediation effect on the association of stroke subtype with increased risk of HT (any ICH, 15.9%; parenchymal hematoma, 13.4%; symptomatic ICH, 14.2%, respectively). Conclusions: Stroke subtype is an independent risk factor for HT within 24 hours following endovascular treatment among acute large vessel occlusion patients. Mediation analyses propose that stroke subtype contributes to HT partly through thrombectomy pass, suggesting a possible pathomechanistic link.

    Abstract: The benefit of endovascular treatment (EVT) for large vessel occlusion in clinical practice in developing countries like China needs to be confirmed. The aim of the study was to determine whether the benefit of EVT for acute ischemic stroke in randomized trials could be generalized to clinical practice in Chinese population. Methods: We conducted a prospective registry of EVT at 111 centers in China. Patients with acute ischemic stroke caused by imaging-confirmed intracranial large vessel occlusion and receiving EVT were included. The primary outcome was functional independence at 90 days defined as a modified Rankin Scale score of 0 to 2. Outcomes of specific subgroups in the anterior circulation were reported and logistic regression was performed to predict the primary outcome. Results: Among the 1793 enrolled patients, 1396 (77.9%) had anterior circulation large vessel occlusion (median age, 66 [56–73] years) and 397 (22.1%) had posterior circulation large vessel occlusion (median age, 64 [55–72] years). Functional independence at 90 days was reached in 45% and 44% in anterior and posterior circulation groups, respectively. For anterior circulation population, underlying intracranial atherosclerotic disease was identified in 29% of patients, with higher functional independence at 90 days (52% versus 44%; P =0.0122) than patients without intracranial atherosclerotic disease. In the anterior circulation population, after adjusting for baseline characteristics, procedure details, and early outcomes, the independent predictors for functional independence at 90 days were age 〈 66 years (odds ratio [OR], 1.733 [95% CI, 1.213–2.476] ), time from onset to puncture 〉 6 hours (OR, 1.536 [95% CI, 1.065–2.216]), local anesthesia (OR, 2.194 [95% CI, 1.325–3.633] ), final modified Thrombolysis in Cerebral Infarction 2b/3 (OR, 2.052 [95% CI, 1.085–3.878]), puncture-to-reperfusion time ≤1.5 hours (OR, 1.628 [95% CI, 1.098–2.413] ), and National Institutes of Health Stroke Scale score 24 hours after the procedure 〈 11 (OR, 9.126 [95% CI, 6.222–13.385]). Conclusions: Despite distinct characteristics in the Chinese population, favorable outcome of EVT can be achieved in clinical practice in China.

    Abstract: The present study was designed to evaluate whether and how itraconazole affects the macrophage polarization and its reactivity to Candida albicans . Methods: Cell toxicity of itraconazole was measured using cell counting kit-8 assay in RAW264.7 cells. The cell models were induced by lipopolysaccharide (LPS), interleukin (IL)-4, or Candida albicans . Levels of cytokines secreted by RAW246.7 treated with itraconazole were detected by Luminex or Cytometric Bead Array compared to the controls without itraconazole treatment, and the expressions of inducible nitric oxide synthase and arginase (Arg) were determined by Western blot. Phagocytosis ability was measured by both flow cytometry and fluorescence microscope. The Student's t test and one-way analysis of variance were used to calculate the differences between groups. Results: In comparison to the control, itraconazole inhibited the growth of the cells in both a time- and a dose-dependent manner. Increased secretion of IL-6 (0.25 μmol/L ITZ [538.03 ± 60.23 pg/mL, P   〈  0.05], 0.5 μmol/L [550.32 ± 47.87 pg/mL, P   〈  0.05] and 1 μmol/L [626.95 ± 75.24 pg/mL, P   〈  0.01] vs . control [370.43 ± 33.98 pg/mL]) and tumor necrosis factor-alpha (TNF-α) (1 μmol/L ITZ vs . control: 2521.51 ± 444.06 pg/mL vs . 1617.85 ± 94.57 pg/mL, P   〈  0.05) were detected in the LPS-induced cell model with itraconazole treatment. In the cells induced by IL-4, itraconazole increased the secretion of IL-6 (1 μmol/L ITZ vs . control: 528.33 ± 11.60 pg/mL vs . 466.99 ± 28.32 pg/mL, P   〈  0.05), TNF-α (1 μmol/L ITZ vs . control: 4.85 ± 0.32 pg/mL vs . 4.30 ± 0.19 pg/mL, P   〈  0.05), and IL-1β (0.25 μmol/L [325.95 ± 13.97 pg/mL, P   〈  0.05], 0.5 μmol/L [332.38 ± 11.97 pg/mL, P   〈  0.05] and 1 μmol/L [334.35 ± 16.23 pg/mL, P   〈  0.05] vs . control [291.62 ± 17.03 pg/mL]), and reduced the secretion of IL-10 (1 μmol/L ITZ vs . control: 7.21 ± 0.68 pg/mL vs . 9.11 ± 0.14 pg/mL, P   〈  0.05). The secretion of IL-6 (1 μmol/L ITZ vs . control: 38.34 ± 1.36 pg/mL vs . 32.32 ± 0.84 pg/mL, P   〈  0.05) and TNF-α (1 μmol/L ITZ vs . control: 1060.17 ± 80.16 pg/mL vs . 890.84 ± 52.82 pg/mL, P   〈  0.01) was improved in Candida albicans -stimulated RAW264.7 cells under the treatment of itraconazole, while the secretion of IL-4 (0.5 μmol/L [2.86 ± 0.20 pg/mL, P   〈  0.05] and 1 μmol/L [2.24 ± 0.33 pg/mL, P   〈  0.001] vs . control [3.91 ± 0.23 pg/mL]) and IL-10 (1 μmol/L ITZ vs . control: 19.46 ± 2.05 pg/mL vs . 25.67 ± 1.95pg/mL, P   〈  0.05) decreased. In all three activated patterns, itraconazole enhanced the expression of inducible nitric oxide synthase ( P   〈  0.01) and slightly inhibited the Arg-1 expression ( P   〈  0.05). Phagocytosis ability of RAW264.7 cells at 1 μmol/L ITZ treatment was increased by 7.53% ± 2.21% ( P   〈  0.01) and 9.73% ± 2.03% ( P   〈  0.01) at the ratio of cells: yeast of 1:4 and 1:8, respectively, in comparison to the control group. Conclusion: Itraconazole improved M1 polarization of RAW264.7 cells and enhanced the phagocytic capacity of RAW264.7 to Candida albicans , indicating a significant immunological enhancement. The study improves the understanding of undergoing mechanisms related to the anti-tumor and anti-infection effects of itraconazole.

    Abstract: To investigate the effect of biliary tract external drainage (BTED) on inflammatory mediators and pathomorphism of intestine, liver, and lung in septic rats. METHOD 48 SD rats (n = 8 per group) were randomized into six groups: control, sepsis, sepsis plus BTED, normal bile (obtained from eight healthy rats), and septic bile infusion for 6 hours respectively to test the effects of BTED bile infusion on cytokines’ expression and tissue injury in the intestine, liver, and lung of septic/normal rats. Co-cultivation of intestinal epithelial cells (IEC-6) with bile for 12 hours was performed to evaluate the potential cytotoxicity of septic bile. Survival rate for sepsis plus BTED rats was detected compared with sepsis without BTED group (n = 20 per group) at 24, 48, and 72 hours, respectively. RESULTS BTED for 6 hours significantly reduced the mRNA expression levels of tumor necrosis factor alpha (TNF-α) and IL-1β (all p 〈 0.05 vs. sepsis group), whereas mRNA expression of TNF-α and IL-1β in the intestine was increased after 6 hours’ septic bile infusion compared with normal bile infusion group (all p 〈 0.05). TNF-α concentration in septic bile was significantly higher than that in the control group ( p 〈 0.001). Tissue injury was significantly attenuated after 6 hours’ BTED. CONCLUSIONS BTED can significantly restrain the mRNA expression of TNF-α and IL-1β in the intestine, liver, and lung and attenuate histological damage in septic rats.
