One hundred patients with focal epilepsy were recruited for the present study and their seizures controlled with antiepileptic drugs. The patients then orally received a capsule of tall gastrodis tuber powder, a traditional Chinese drug, and underwent single photon emission computed tomography, long-term electroencephalogram, and CT/MRI. Blood drug levels were monitored throughout the study. Before treatment with tall gastrodis tuber, 35 of the 100 cases had abnormal CT/MRI scans; 79 cases had abnormal single photon emission computed tomography images; 86 cases had abnormal electroencephalogram; and a total of 146 abnormal perfusion foci were observed across the 100 subjects. After treatment, the number of patients with normal single photon emission computed tomography images increased by 12; normal electroencephalogram was observed in an additional 27 cases and the number of patients with epileptiform discharge decreased by 29 （34% of 86）; the total number of abnormal perfusion foci decreased by 52 （36%） and changes in abnormal loci were visible in 65 patients. These changes indicate that the administration of tall gastrodis tuber in combination with antiepileptic drugs repairs abnormal perfusion foci in patients with focal epilepsy Our results demonstrate that traditional Chinese drugs can repair abnormal perfusion foci and, as such, are a promising new pathway in the treatment of focal epilepsy.

设计一种新型Al-Mg-Si-Cu铝合金,合金成分为Al-1.04Mg-0.85Si-0.018Cu(质量分数)。采用金相观察、差热分析(DTA)、扫描电镜(SEM)和能谱分析(EDS)研究合金铸态与均匀化态的显微组织演化和成分分布。结果表明:新型Al-Mg-Si-Cu铝合金的铸态组织枝晶偏析严重,合金元素Si、Mg和Fe在晶内及晶界分布不均匀;550℃×24 h均匀化处理后,合金中非平衡低熔点共晶组织和Mg2Si相基本溶入基体,Fe元素偏析难以通过均匀化消除,均匀化后,晶界上部分β-Al5FeSi相转变成α-Al8Fe2Si相;该合金的过烧温度为574.5℃,最佳均匀化制度为550℃×24 h;合金铸态和均匀化后维氏硬度分别为58HV和78HV,比6061合金分别提高了20%和85%。

微小RNA-942在肝癌组织的表达及其对肝癌细胞增殖、侵袭能力的影响

2012第二届国际神经再生高峰论坛

作者： Weimin Wang Tiancheng Wang Jiang Ye Yaqing Liu xiaoli dang Wenjun Song Yinping Wu Zhenyu Fan Epilepsy Centre Second Hospital Lanzhou University

Interictal hypoperfusion and ictal hyperperfusion appear in patients with epilepsy. Antiepileptic drugs can control seizures, but do not repair the abnormal perfusion foci. Recent studies have investigated new principles for treatment of epilepsy, including repair of the initial insult, neuroprotection, antagonism of epileptogenesis and disease modification. It was found that the epileptic focus is chronic, localized, irregular, single or multiple, sensitive, and dynamic. Four types of abnormal perfusion foci and 20 subtypes have been observed in epilepsy patients. Abnormal perfusion foci were reversible and irreversible. Patients can "survive with abnormal perfusion foci", and abnormal perfusion focus can be repaired. Dynamic observation of abnormal perfusion foci can be used as an indicator for prognosis of epilepsy, withdrawal and relapse. Temporal lobe has a significantly high incidence of abnormal perfusion focus, but the lowest repair rate. The total number of abnormal perfusion foci was reduced by 1/3-2/3 after repair. However, repair of hypoperfusion is the main target. The incidence of hyperperfusion foci in infant children was significantly higher than in adolescents or adults. Electroencephalogram analysis was inconsistent with abnormal perfusion foci. Carbamazepine and valproic acid significantly reduced the number of abnormal perfusion foci. Antiepileptic drugs combined with traditional Chinese medicine can reduce brain damage and improve the control and cure rates of epilepsy, and have potential for the repair of abnormal perfusion foci in patients with epilepsy.

目的观察微小RNA（miRNA，miR）-942在肝细胞肝癌（HCC）组织中的表达及其对肝癌细胞增殖、侵袭能力的影响。方法采用实时定量聚合酶链反应（Real-time PCR）检测70例肝癌和癌旁组织miR-942的表达；将Huh7细胞分别转染miRNA随机序列（阴性对照组）、miR-942模拟物（miR-942模拟物组）和miR-942抑制物（miR-942抑制物组）后，噻唑蓝（MTT）法和Transwell实验观察Huh7细胞增殖和侵袭能力变化；Western blot检测Huh7细胞增殖细胞核抗原（PCNA）和基质金属蛋白酶-9（MMP-9）的蛋白表达。结果miR-942在肝癌组织中表达量（0.92±0.08）与癌旁组织（0.42±0.05）比较显著上调（t＝5.712，P＝0.000）；MTT细胞增殖实验结果显示5 d后miR-942抑制物组Huh7细胞吸光度（A）值显著低于阴性对照组和miR-942模拟物组（0.79±0.02比1.02±0.04，t＝7.513，P＝0.001；0.79±0.02比1.51±0.12，t＝8.621，P＝0.001）；Transwell结果显示miR-942抑制物组侵袭转移细胞数明显减少[（59.13±5.41）个比（97.26±11.13）个，t＝11.712，P＝0.000；（59.13±5.41）个比（99.42±12.13）个，t＝12.113，P＝0.000]；Western blot结果显示PCNA和MMP-9蛋白在miR-942抑制物组的表达分别下调了80.1%和56.3%（t＝5.231，P＝0.000；t＝6.415，P＝0.000）。结论miR-942在肝癌组织中高表达，下调miR-942可抑制肝癌细胞的增殖和侵袭，其机制与下调PCNA和MMP-9表达有关。
