近10年来,高场强MRI系统在医学领域的应用和研究不断深入,但其安装和扫描条件要求较高,运行成本昂贵,限制了其在基层医院的普及。相比之下,低场强(0.01~1.0 T)MRI虽然成本较低,但因其成像性能欠佳,也未能在临床实践中发挥更大的作用。随着技术的不断发展,目前低场强MRI有望实现类似于高场强MRI系统的各种应用,通过优化软件、硬件设计和技术革新,低场强MRI可以在保持成本经济、便于转运优势的同时提高信噪比,达到提高诊断性能,更广泛地应用于临床实际场景的目标。特别是在急重症诊断方面,低场强MRI有望成为脑血管疾病诊断和监测的重要工具之一。本文追溯了低场强MRI的发展历程,对其在神经系统疾病临床应用中的进展进行了综述,旨在为未来低场强MRI技术的发展探寻方向。

Background In patients with a minor ischaemic stroke or transient ischaemic attack(TIA),separate trials have shown that dual antiplatelet therapy with clopidogrel plus aspirin(clopidogrel-aspirin)or ticagrelor plus aspirin(ticagrelor-aspirin)are more effective than aspirin alone in stroke secondary ***,these two sets of combination have not been directly *** clopidogrel was less effective in stroke patients who were CYP2C19 loss-of function(LOF)allele carriers,whether ticagrelor-aspirin is clinically superior to clopidogrel-aspirin in this subgroup of patients with stroke is *** To describe the rationale and design considerations of the Clopidogrel in High-risk patients with Acute Non-disabling Cerebrovascular Events(CHANCE-2)*** CHANCE-2 is a randomised,double-blind,double-dummy,placebo-controlled,multicentre trial that compares two dual antiplatelet strategies for minor stroke or TIA patients who are CYP2C19 LOF allele carriers:ticagrelor(180 mg loading dose on day 1 followed by 90 mg twice daily on days 2-90)or clopidogrel(300 mg loading dose on day 1 followed by 75 mg daily on days 2-90),plus open-label aspirin with a dose of 75-300 mg on day 1 followed by 75 mg daily on day *** will be followed for 1 *** outcomes The primary efficacy outcome is any stroke(ischaemic or haemorrhagic)within 3 months and the primary safety outcome is any severe or moderate bleeding event within 3 *** The CHANCE-2 trial will evaluate whether ticagrelor-aspirin is superior to clopidogrel-aspirin for minor stroke or TIA patients who are CYP2C19 LOF allele carriers.

BACKGROUND： Collagen-heparin sulfate scaffolds have been widely used to repair nerve injury and promote nerve regeneration. Previous research has evaluated scaffold biocompatibility by measuring gliocyte proliferation but not neuronal apoptosis. OBJECTIVE： To explore the biocompatibility of collagen-heparin sulfate scaffold in porcine brain by detecting peripheral neural apoptosis and protein expression. DESIGN, TIME AND SETTING： A randomized, controlled animal experiment was performed at the Laboratory of Neurology, Tongji Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology, between March and June, 2008. MATERIALS： Rabbit anti-human Bax, Caspase-3 polyclonal antibody, rat anti-human Bcl-2 polyclonal antibody, streptavidin biotin-peroxidase complex （SABC） immunohistochemical kit, and TUNEL kit （Roche, USA） were used in this study. METHODS： Twenty adult piglets were randomly evenly divided into implantation and control groups A collagen-heparin sulfate scaffold was implanted from the anterior fontanelle into the brain in the implantation group. The same puncture but no scaffold implantation was made in the control group. MAIN OUTCOME MEASURES： Cell apoptosis was detected using TUNEL; Bax, Bcl-2, and Caspase-3 expressions were measured using the SABC method. RESULTS： At days 1,3, 7, and 14 after scaffold implantation, a few apoptotic cells were observed in the brain tissues near the puncture site, with more apoptotic cells in the implantation group （P 〈 0.05）. However, both groups showed similar apoptosis levels by day 30 after implantation. Implantation increased Bax, Bcl-2, and Caspase-3 expressions on days 3 and 7 after implantation （P 〈 0.05） but decreased the ratio of Bcl-2 to Bax in the implantation group was significantly lower on days 3 and 7 （P 〈 0.05）, with no significant difference by day 30 after implantation （P 〉 0.05）. CONCLUSION： The collagen-heparin sulfate scaffold has good biocompatibility to porcine brain tis
