RESUMEN
Objective To evaluate the efficacy and safety of using alteplase for intravenous thrombolysis combined with vascular intervention for treatment of patients with acute intracranial large arterial occlusion.Methods Clinical data of 7 patients with acute intracranial large arterial occlusion treated by using alteplase for intravenous thrombolysis combined with intravascular intervention admitted to Department of Neurosurgery in Affiliated Hospital of the Logistics University of Cinese People's Armed Police Force from July 2015 to August 2016 were retrospectively analyzed.All the 7 patients were treated by alteplase dry powder (50 mg or 20 mg each ampule),solvent dose was 0.9 mg/kg,the maximum dose being ＜ 90 mg,firstly 10％ dose was intravenously injected,and the remaining dose was continuously infused into a vein in 60 minutes,during or after intravenous thrombolysis,digital subtraction angiography (DSA) was performed immediately,and according to the results of the angiography,at least one of the 3 kinds of intravascular mechanical intervention therapy,thrombectomy,balloon dilatation or stent placement,were chosen,and 24 hours after surgery,the anti-platelet aggregation drug and calcium channel antagonists were given,The effect of interventional therapy was analyzed,and the clinical outcome of 90-day treatment was evaluated.Results The mean age of the patients was (60.0 ± 12.6) years.Seven patients all successfully completed the treatment,and satisfactory re-canalization was achieved [they all obtained grade 3 or 2b in accord with the gradation of Thrombolysis in Cerebral Ischemia Scale (TICI)] in all the 7 cases (100％),after treatment,the National Institutes of Health Stroke Scale (NIHSS) score was significantly lower than that before treatment (5.86 ±4.10 vs.19.71 ± 5.56,P ＜0.01).Clinical outcome of 90-day follow up was excellent [Modified Rankin Scale (mRS) score 0-2] in 3 cases (42.8％).Conclusion Using alteplase for intravenous thrombolysis combined with endovascular intervention for treatment of patients with acute intracranial large arterial occlusion can achieve good re-canalization rate.
RESUMEN
Objective To explore the efficacy of ultra-early stent-assisted coil (SAC) in the treatment of intracranial rupture of wide- necked aneurysms. Methods The angiographic and clinical data of 24 patients (including 8 male, 16 female, age ranged from 29 to 86 years, with a median age 59) with acutely ruptured wide-necked intracranial aneurysms treated with SAC were retrospectively analyzed. The postoperative complications and clinical results were observed. The postoperative embolization was assessed according to the Raymond grading standard. The assessment of the follow-up results from 6 to 12 months after procedure was observed according to the modified Rankin Scale (mRS) score. Results Procedure-related complications occurred in 3 patients (12.5%). All of them were hemorrhagic events, of which 2 cases died. Perioperative death was found in 3 cases. Of the 19 surviving patients, 17 showed good recovery (mRS 0-2). After 6 to 12 months of DSA, no recurrence of aneurysm was found in 10 follow-up patients. Conclusion Ultra-early stent-assisted coil treatment for intracranial wide-neck rupture aneurysm can improve the success rate of embolization and reduce the recurrence.

RESUMEN
Objective To observe the changes of TNF-α and NF-κB after different doses of nalmefene hydrochloride (NAL) therapy for traumatic brain injury (TBI) in an effort to identify the effect of NAL on TBI-induced inflammatory response and the possible mechanism.Methods A model of TBI in the rat was produced using the improved Feeney' s free-fall impact method.The animals were randomly divided into sham group,TBI group,TBI + large dose of NAL (ip,0.2 mg/kg) group (TBI + NAL1group),TBI + medial dose of NAL (ip,0.14 mg/kg) group (TBI + NAL2 group),TBI + small dose of NAL (ip,0.07 mg/kg) group (TBI + NAL3 group).Form of brain tissues in each group was observed and mRNA levels of TNF-α and NF-κB were measured by real-time quantitative PCR assay.Results HE staining revealed severe injury and inflammatory infiltration of brain parenchyma in TBI group ;on the contrary,the situation ameliorated in TBI + NAL1 group,TBI + NAL2 group and TBI + NAL3group,with especially obvious improvement in TBI + NAL2 group.In PCR assay,significant expression of NF-κB and TNF-α was observed at post-TBI days 1,3,5 and 7 (P ＜ 0.05),followed by great reverse after NAL therapy (P ＜ 0.05),particularly in TBI + NAL2 group.Conclusions NAL can reduce the inflammation response to TBI and promote post-injury recovery.Moreover,there exists a NAL concentration window.
