ObjectiveTo explore the effect of fingolimod (FTY720) on secondary nerve injury after thalamic-ventricle hemorrhage (TH-IVH) in rats.MethodsAdult male Sprague Dawley rats (clean animal) were randomly divided into 3 groups: sham group, TH-IVH group, and intervention group (FTY720 group), with 6 rats in each group. TH-IVH model was established in both TH-IVH group and FTY720 group, but only the rats in FTY720 group were treated with FTY720. The observation was conducted at the 1st, 3rd and 7th day after modeling. The main observation index included scores of neurological function, change of body weight, water content of brain tissue, the activation of inflammatory cells, the degree of neuronal degeneration and apoptosis, and the level of cell autophagy.ResultsAt the 1st, 3rd and 7th day after modeling, the change of body weight, the neurological score, brain edema and microglia activation in TH-IVH group were statistically different from those in sham group and FTY720 group (P<0.05). The number of degenerated neurons and the number of apoptotic cells in TH-IVH group were statistically different from those in sham group and FTY720 group at the 1st and 3rd day after modeling (P<0.05). The differences in the ratio of LC3Ⅱ/LC3Ⅰ protein expression andBcl-2/Bax expression were statistically significant between FTY720 group and TH-IVH group at the 1st and 3rd day after modeling (P<0.05).ConclusionsFTY720 can improve neurological function of the TH-IVH model in the acute phase, and has certain neuroprotective effect. The neuroprotective effect of FTY720 may be associated with neuronal autophagy and apoptosis regulation and immunosuppression.
ObjectiveTo investigate the application of stereoelectroencephalography (SEEG) in the refractory epilepsy related to periventricular nodular heterotopia (PNH). MethodsTen patients with drug-resistant epilepsy related to PNHs from Guangdong Sanjiu Brain Hospital and the First Affiliated Hospital of Jinan University from April 2017 to February 2021 were studied. Electrodes were implanted based on non-invasive preoperative evaluation. Then long-term monitoring of SEEG was carried out. The patterns of epileptogenic zone (EZ) were divided into four categories based on the ictal SEEG: A. only the nodules started; B. nodules and cortex synchronous initiation; C. the cortex initiation with early spreading to nodules; D. only cortex initiation. All patients underwent SEEG-guided radiofrequency thermocoagulation (RFTC), with a follow-up of at least 12 months. ResultsAll cases were multiple nodules. Four cases were unilateral and six bilateral. Eight cases were distributed in posterior pattern, and one in anterior pattern and one in diffused pattern, respectively. Seven patients had only PNH (pure PNH) and three patients were associated with other overlying cortex malformations (PNH plus). The EZ patterns of all cases were confirmed by the ictal SEEG: six patients were in pure type A, two patients were in pure type B, one patient in type A+B and one in type A+B+C, respectively. In eight patients SEEG-guided RF-TC was targeted only to PNHs; and in two patients RFTC was directed to both heterotopias and related cortical regions. The mean follow up was (33.4±14.0) months (12 ~ 58 months). Eight patients (in pure type A or type A included) were seizure free. Two patients were effective. None of the patients had significant postoperative complications or sequelae. ConclusionThe epileptic network of Epilepsy associated with nodular heterotopia may be individualized. Not all nodules are always epileptogenic, the role of each nodule in the epileptic network may be different. And multiple epileptic patterns may occur simultaneously in the same patient. SEEG can provide individualized diagnosis and treatment, be helpful to prognosis.
【摘要】 目的 研究改良Paine点侧脑室额角穿刺的解剖基础及临床应用。 方法 利用MRI模型的构建，模拟改良Paine点穿刺侧脑室额角。测量穿刺距离、角度及其对Broca语言功能区和尾状核的影响。改良Paine点（Pm点）比Paine点高1 cm，更加远离Broca语言功能区，穿刺时需要与轴面夹角20°向下，可以越过尾状核头从侧脑室额角上壁进入脑室；与矢状面夹角约70°向下、冠状面夹角约20°向后穿刺。从皮层计算进针4.0~5.5 cm可进入侧脑室额角。 结果 同期7例颅内动脉瘤患者术中应用Pm点穿刺成功，术后无语言功能障碍，复查头颅CT无穿刺道及尾状核头出血现象。 结论 Pm点法定位方法简便准确，能避免Broca语言功能区和尾状核头部的损伤，有一定临床应用推广价值。【Abstract】 Objective To analyze the anatomic characteristics and clinical application of modified Paine entry point (Pm) for lateral ventricular puncture through pterional approach. Methods We simulated the modified Paine entry point for lateral ventricular frontal horn puncture by reconstructing the model of MRI. Distance and angles of the puncture path were measured to evaluate the influence upon the language areas of Broca and the head of the caudate nucleus. The Pm point is 1 cm higher than the Paine point, so it is more far away from the Broca area. The direction of the puncture path should be 20° downward with the axial plane, 70° downward with the sagittal plane and 20° backward with the coronal plane. The catheter was inserted into the ventricle 4.0 to 5.5 cm deep to the cortex. Results Seven patients with intracranial aneurysms underwent ventricular puncture successfully through the Pm point in operation. None of them suffered language dysfunction or hemorrhage lesions in the caudate nucleus by the computed tomography. Conclusion The modified Paine entry point can be located accurately and has the clinical value for preventing damage of the Broca area and the caudate nucleus.
