RESUMEN
Objective To evaluate the cost-effectiveness of edaravone dexborneol versus edaravone alone combined with conventional therapy in patients with acute ischemic stroke(AIS).Methods From the perspective of the healthcare systems,a decision tree model was constructed using the data from the randomized double-blind comparative trial of edaravone dexborneol in the treatment of acute ischemic stroke(TASTE trial).Cost-utility analysis was used to evaluate the health benefits of edaravone dexborneol at 1 month and 5 years.The robustness of the results was tested by single factor sensitivity analysis and probability sensitivity analysis.Results For AIS patients,the 1-month incremental cost-utility ratio was 53 212.89 yuan/quality-adjusted life-year(QALY),and the 5-year incremental cost-utility ratio was 49 631.25 yuan/QALY,both of which were smaller than China's per capita GDP in 2022(85 698 yuan).Univariate sensitivity analysis showed that the change of NIHSS score in 2 groups of improved patients,the probability of improvement in 2 groups and the probability of deterioration in edaravone group were the most influential factors on the outcome of incremental cost effectiveness.The results of probabilistic sensitivity analysis showed that edaravone dexcborneol was more economical when WTP was 1 times China's per capita GDP in 2022.Conclusion Edaravon dexborneol is a more effective and economical treatment for acute ischemic stroke patients than edaravone alone.
RESUMEN
OBJECTIVE To evaluate efficacy， safety and cost-effectiveness of edaravone dexborneol and compound porcine cerebroside ganglioside in the treatment of acute ischemic stroke， and to provide decision-making reference for clinical treatment selection. METHODS The medical records of 488 patients with acute ischemic stroke hospitalized from Jan. 2021 to Dec. 2021 were collected and divided into two groups according to the treatment plan， i.e. 268 patients in edaravone dexborneol group， and 220 patients in compound porcine cerebroside ganglioside group. After baseline levels of the two groups were balanced using propensity score matching method， curative effect was evaluated according to the changes of NIHSS scores before and after treatment； the occurrence of adverse drug reactions in patients were collected from the hospital adverse reaction reporting system； from the perspective of China’s health system， the cost-effectiveness of the two options were analyzed， and one-way sensitivity analysis was conducted. RESULTS After the propensity score matching， 125 patients were included in the edaravone dexborneol group and compound porcine cerebroside ganglioside group， respectively. The response rates were 81.6% and 74.4%， respectively， with no significant difference. The average costs were 13 560.30 yuan and 14 958.68 yuan， respectively； the cost of edaravone dexborneol group was lower than that of compound porcine cerebroside ganglioside group. No adverse reaction reporting information was retrieved in both groups. Results of one-way sensitivity analysis showed that other drug costs in compound porcine cerebroside ganglioside group was relatively sensitive parameters. CONCLUSIONS Short-term efficacy and safety of edaravone dexborneol are equivalent to those of compound porcine cerebroside ganglioside in treating acute ischemic stroke. But edaravone dexborneol regimen had lower cost and is a more economical scheme.

RESUMEN
Objective:To investigate the efficacy and safety of recombinant tissue plasminogen activator (rt-PA) intravenous thrombolysis combined with edaravone dexborneol at different timing in super elderly patients (aged≥85 years) with moderate to severe acute ischemic stroke (AIS).Methods:A prospective study was performed. Seventy-one super elderly patients with moderate to severe AIS treated with rt-PA intravenous thrombolysis combined with edaravone dexborneol from December 2020 to March 2023 in Department of Neurology, Affiliated Fourth Central Hospital of Nankai University were selected and randomly divided into early group ( n=35) and advanced group ( n=36); patients in the early group were given edaravone dexborneol immediately after rt-PA intravenous thrombolysis, and patients in the advanced group were given edaravone dexborneol 24 h after rt-PA intravenous thrombolysis. In addition, 31 patients with moderate to severe AIS received rt-PA intravenous thrombolysis only in Department of Neurology of the hospital from August 2018 to December 2020 were selected as control group. Differences in efficacy and safety indexes among the 3 groups were compared. Results:After 7 d of treatment, the improvement rate of neurological function in early group was significantly higher than that in control group and advanced group ( P<0.05). After 90 d of treatment, modified Rankin scale (mRS) scores in early group were statistically lower than those in control group and advanced group ( P<0.05); good prognosis rate in early group was statistically higher than that in control group and advanced group ( P<0.05). The incidences of intracranial hemorrhage and symptomatic intracranial hemorrhage in early group were significantly lower than those in control group and advanced group ( P<0.05). After 30 and 90 d of treatment, the advanced group had significantly lower mortality than the control group, but significantly higher mortality than the early group ( P<0.05). Conclusion:Edaravone dexborneol immediately after rt-PA intravenous thrombolysis is the optimal timing for super elderly patients with moderate to severe AIS, which can improve the efficacy and safety.

Objective:To observe the effect of edaravone dexborneol on anxiety and depression after stroke in rats, and to explore its possible mechanism.Methods:Totally 120 healthy adult male SD rats were randomly divided into sham operation group (sham), ischemia-reperfusion group (MCAO), edaravone group (Eda) and edaravone dexborneol group (ED) with 30 in each group.The middle cerebral artery occlusion (MCAO) model was established by thread occlusion.Rats in ED group and Eda group were intraperitoneally injected with edaravone(8 mg·kg -1·d -1) and edaravone dexborneol(edaravone: 8 mg·kg -1·d -1, dexborneol: 2 mg·kg -1·d -1) respectively.And rats in the other two groups were intraperitoneally injected with the same volume of normal saline.Some rats were killed after continuous administration for 3 days to detect molecular indexes, and the remaining rats were tested for behavior after continuous administration for 14 days.The levels of neclear factor κB(NF-κB)、phosphorylated NF-κB(p-NF-κB)、tumor necrosis α(TNF-α)、interleukin 1β(IL-1β) were detected by Western blot.The mRNA levels of TNF-α, IL-1β, cluster of differentiation 86(CD86), cluster of differentiation 206(CD206), inducible nitric oxide synthase(iNOS) were detected by RT-qPCR.M1 type microglia labeled with CD68, microglia labeled with ionized calcium binding adaptor molecule 1(Iba1) and neurons labeled with microtubule-associated protein 2(MAP2) were detected by immunofluorescence staining.The cerebral infarction volume was measured by TTC staining.Depression and anxiety behavior after stroke in rats was observed by the open field test and elevated plus maze test.SPSS 17.0 software was used for statistical analysis of the data.One-way ANOVA was used for multiple group comparison, and LSD-t test was used for pairwise comparison. Results:(1) The behavioral results showed that 14 days after ischemia-reperfusion, the number of entering into the open arm, the time spent in the open arm, and the time spent in the central area of the open field in the MCAO group were lower than those in the sham group ( t=20.77, 6.02, 14.63, all P<0.05). The number of entering into the open arm, the time spent in the open arm, and the time spent in the central area of the field in the ED group ( (16.22±0.49) times, (69.11±17.08) s, (3.80±0.37) s) were higher than those in the MCAO group ( (8.14±0.60) times, (41.18±9.81) s, (0.33±0.39) s) ( t=4.69, 0.38, 2.27, all P<0.05) and Eda group ( (11.11±0.26) times, (45.26±17.16) s, (1.14±0.19) s) ( t=8.63, 2.50, 7.86, all P<0.05). (2) Western blot results showed that 3 days after ischemia-reperfusion, p-NF-κB/NF-κB, TNF-α, and IL-1β levels in the MCAO group were higher than those in the sham group ( t=15.35, 12.35, 7.23, all P<0.05). The levels of p-NF-κB/NF-κB (0.49±0.02), TNF-α (0.73±0.03), IL-1β (0.61±0.01) of ischemic penumbra cortex in ED group were significantly lower than those of the MCAO group ( (1.14±0.05), (1.13±0.07), (1.34±0.14)) ( t=14.58, 7.86, 5.65, all P<0.05) and Eda group ( (0.93±0.03), (0.89±0.02), (1.04±0.36) ) ( t=9.82, 3.07, 3.30, all P<0.05). (3) RT-qPCR results showed that the level of TNF-α mRNA (1.98±0.18), IL-1β mRNA (2.00±0.35), CD86 mRNA (1.56±0.20) and iNOS mRNA (2.01±0.12) in the peri-infarct cortex of ED group were lower than those in the MCAO group ( (5.12±0.24), ( 8.15±0.22), (6.03±0.13), (7.20±0.09) ) ( t=7.86, 16.88, 16.55, 37.25, all P<0.05) and Eda group ( (2.85±0.07), (5.43±0.26), (2.67±0.27), (3.58±0.11) ) ( t=3.71, 9.41, 4.13, 11.30, all P<0.05). The level of CD206 mRNA in the peri-infarct cortex of the ED group (3.98±0.25) was higher than that in the MCAO group (2.00±0.11) ( t=7.08, P<0.05) and Eda group (3.17±0.09) ( t=3.25, P<0.05). (4) The results of immunofluorescence staining showed that the ratio of polarized M1 microglia in the peri-infarct cortex and striatum in the ED group ((20.36±9.23)%, (18.26±5.98)%)were lower than those in the MCAO group ( (83.69±12.79)%, (61.25±33.26)%) ( t=5.23, 3.02, both P<0.05) and Eda group((42.16±13.13)%, (40.23±14.22)%)( t=3.12, 2.08, both P<0.05). In addition, the number of neurons marked with MAP2 of peri-infarct cortex in the MCAO group was lower than that in the sham group( t=8.02, P<0.05), and the number of neurons marded with MAP2 of peri-infarct cortex in the ED group ((53.07±17.90) /scope) was higher than that in the MCAO group ( (26.27±9.95) /scope) ( t=6.89, P<0.05) and Eda group ( (38.69±12.03)/scope) ( t=5.26, P<0.05). (5) The results of TTC staining showed that the cerebral infarction volume in ED group ( (10.31±1.03)%) was lower than that in the MCAO group ( (34.71±1.74)%) ( t=15.31, P<0.05) and Eda group ( (26.05±1.00)%) ( t=9.88, P<0.05). Conclusion:Edaravone dexborneol can alleviate anxiety and depression in rats with cerebral ischemia-reperfusion, which may be related to the inhibition of M1 microglial polarization, the down-regulation of NF-κB signaling pathway and the enhancement of neuronal structural stability.
