RESUMO
Objective:To explore the relation of plasma Elabela with 3-month prognoses in large vessel occlusion-acute ischemic stroke (LVO-AIS) patients accepted endovascular thrombectomy (EVT).Methods:A prospective study was performed; 94 LVO-AIS patients aceepted EVT in Department of Neurology, Anhui Provincal Hospital, Anhui Medical University from August 2020 to August 2022 were selected. Plasma Elabela was detected before EVT, and 24 and 72 h after EVT. Modified Rankin scale (mRS) was used to evaluate the prognoses of the patients 3 months after EVT; differences in clinical data and plasma Elabela level between the good prognosis group and poor prognosis group were compared. Independent influencing factors for prognoses of LVO-AIS patients 3 months after EVT were analyzed by multivariate Logistic regression. Receiver operating characteristic (ROC) curve was used to analyze the efficacy of Elabela in predicting prognoses of patients with LVO-AIS 3 months after EVT.Results:Compared with the poor prognosis group, the good prognosis group had significantly lower percentages of patients with stroke history and diabetes, and lower NIHSS scores at admission ( P<0.05). Elabela level in the good prognosis group was significantly higher than that in the poor prognosis group 72 h after EVT ( P<0.05). Multivariate Logistic regression analysis showed that stroke history ( OR=0.148, P=0.037, 95% CI: 0.025-0.889), diabetes mellitus ( OR=0.148, P=0.037, 95% CI: 0.025-0.889), hypertension history ( OR=3.488, P=0.024, 95% CI: 1.177-10.339), and Elabela level 72 h after EVT ( OR=1.064, P=0.005, 95% CI: 1.019-1.111) were independent influencing factors for prognoses of LVO-AIS patients 3 months after EVT. ROC curve showed that area under ROC curve of plasma Elabela level 72 h after EVT in predicting prognosies of LVO-AIS patients 3 months after surgery was 0.718 ( P<0.001, 95% CI: 0.614-0.822). Conclusion:Plasma Elabela level 72 h after EVT may be a potential prognostic biomarker for LVO-AIS patients after EVT.
RESUMO
Background@#and Purpose To examine the clinical and safety outcomes after endovascular treatment (EVT) for acute basilar artery occlusion (BAO) with different anesthetic modalities. @*Methods@#This was a retrospective analysis using data from the Endovascular Treatment for Acute Basilar Artery Occlusion (ATTENTION) registry. Patients were divided into two groups defined by anesthetic modality performed during EVT: general anesthesia (GA) or non-general anesthesia (non-GA). The association between anesthetic management and clinical outcomes was evaluated in a propensity score matched (PSM) cohort and an inverse probability of treatment weighting (IPTW) cohort to adjust for imbalances between the two groups. @*Results@#Our analytic sample included 1,672 patients from 48 centers. The anesthetic modality was GA in 769 (46.0%) and non-GA in 903 (54.0%) patients. In our primary analysis with the PSM-based cohort, non-GA was comparable to GA concerning the primary outcome (adjusted common odds ratio [acOR], 1.01; 95% confidence interval [CI], 0.82 to 1.25; P=0.91). Mortality at 90 days was 38.4% in the GA group and 35.8% in the non-GA group (adjusted risk ratio, 0.95; 95% CI, 0.83 to 1.08; P=0.44). In our secondary analysis with the IPTW-based cohort, the anesthetic modality was significantly associated with the distribution of modified Rankin Scale at 90 days (acOR: 1.45 [95% CI: 1.20 to 1.75]). @*Conclusion@#In this nationally-representative observational study, acute ischemic stroke patients due to BAO undergoing EVT without GA had similar clinical and safety outcomes compared with patients treated with GA. These findings provide the basis for large-scale randomized controlled trials to test whether anesthetic management provides meaningful clinical effects for patients undergoing EVT.
RESUMO
Objective:To investigate the influencing factors for prognoses of patients with acute basilar artery occlusion (BAO) receiving bridging therapy (intravenous thrombolysis [IVT] combined with endovascular treatment [EVT]).Methods:The clinical and imaging data of 404 patients with acute BAO accepted bridging therapy were collected from Endovascular Treatment for acute Basilar Artery Occlusion (ATTENTION) database. The prognoses of these patients were evaluated by modified Rankin Scale (mRS) 90 d after treatment. The differences of clinical and imaging data between patients with good prognosis and poor prognosis were compared, and the independent influencing factors for prognoses were analyzed by multivariate Logistic regression.Results:Among 404 patients with acute BAO, 156 (39%) had good prognosis and 248 (61%) had poor prognosis. Compared with the good prognosis group, the poor prognosis group had significantly higher proportions of patients older than 65 years, patients with NIHSS scores>20 on admission, and patients with thrombectomy frequency>1, significantly lower proportion of patients with successful vascular recanalization, and significantly different distribution of occlusive sites ( P<0.05). Multivariate Logistic regression analysis showed that NIHSS scores on admission>20 ( OR=0.510, 95%CI: 0.331-0.786, P=0.002), and occlusion site at the distal basilar artery ( OR=2.241, 95%CI: 1.357-3.702, P=0.002), thrombectomy frequency>1 ( OR=0.523, 95%CI: 0.339-0.807, P=0.003) and successful vascular recanalization ( OR=2.022, 95%CI: 1.032-3.961, P=0.040) were independent influencing factors for good prognosis of these patients. Conclusion:Acute BAO patients with NIHSS scores>20 on admission, thrombectomy frequency>1, non-distal BAO occlusion, and unsuccessful recanalization have poor prognosis after bridging therapy.
RESUMO
Objective: To establish an HPLC method for the determination of baicalin and phillyrin in Qinqiao oral solutions. Methods:The column was Inertsil ODS-SP(250 mm × 4. 6 mm, 5 μm). The mobile phase consisted of acetonitrile-phosphate buffer (11. 5 g ammonium dihydrogen phosphate was dissolved in water, and then 1ml phosphoric acid was added, finally the solution was di-luted to 1 000 ml by water)(75∶25). The flow rate was 1. 0 ml·min-1, the detection wavelength was at 278 nm and the column tem-perature was 25℃. Results:The calibration curve was linear within the range of 0. 203-4. 064 μg(r=0. 999 8) for baicalin and 0. 182-3. 648μg(r=0. 999 7) for phillyrin. The average recovery was 100. 9% with RSD of 1. 7% (n=5) and 100. 5% with RSD of 1. 4% (n=5), respectively. Conclusion:The method is simple, practicable, accurate and rapid, which can be applied in the determi-nation of baicalin and phillyrin in Qinqiao oral solutions.
