Chiari Ⅰ型畸形手术前后的诱发电位研究

[目的]研究Chiari Ⅰ型畸形患者手术前后的诱发电位的变化规律，观察手术前脊髓空洞的程度与诱发电位变化之间的关系。[方法]对2003年10月-2004年9月收治的15例Chiari Ⅰ型畸形患者，采取寰枕减压术、硬膜成形术。手术前第1～3d和手术后第10—14d分别检测BAEP、SEP、MEP，然后对这些患者经过6个月的随访，进行脊髓功能JOA评分和MRI复查。[结果]15例Chiari Ⅰ型畸形患者手术前14例SEP、MEP异常，手术后临床症状均有所缓解，脊髓功能JOA改善率为60．3％，MRI复查显示脊髓空洞明显缩小、诱发电位SEP检测P40-N22、N20-N13潜伏期与MEP检测中枢传导时间CMCT值和BAEP检测Ⅰ—Ⅴ峰间期，三者测的值比术前均缩短，差异有显著性。同时发现Chiari畸形患者的SEP与MEP检查测得皮层值术后比术前缩短，差异有显著性，而外周神经传导时间术后与术前比较却没有任何变化。[结论]诱发电位可以作为评价Chiari Ⅰ型畸形手术前后效果的客观而相对准确的检查方法。     

Feasibility of establishing cerebral ischemia models by using aerocyst-blocking bilateral ascending pharyngeal artery of piglets Imaging assessment

BACKGROUND: The cerebral ischemia and ischemia/reperfusion animal models are used to simulate the human cerebrovascular diseases is one of the popular topics of neurological science recently. To study the pathophysiology, pathogenesis, prophylaxis and treatment of ischemic cerebrovascular diseases and to establish the ideal animal model that is the most similar to the human cerebral ischemia, are the topics that the people generally cared about. OBJECTIVE: To evaluate the effects of aerocyst-blocking bilateral ascending pharyngeal artery on the establishment of cerebral ischemia models by using digital subtraction angiography (DSA), magnetic resonance diffusion-weighted imaging (DWI) and magnetic resonance perfusion-weighted imaging (PWI). DESIGN: Repetitive measure animal experiment. SETTING: Zhongshan Hospital Affiliated to Dalian University. MATERIALS: The experiment was carried out in the Animal Laboratory (Provincial Laboratory), Zhongshan Hospital of Dalian Univeristy from January to May 2006. A total of 14 domestic piglets, of 6 months old, weighing 12–15 kg, of either gender, were selected from Animal Experimental Center, Dalian University. Multistar T.O.P digital subtraction angiography machine was provided by Siemens Company, German. METHODS: Aerocyst-blocking bilateral ascending pharyngeal artery was used to establish cerebral ischemia models. And then, Multistar T.O.P. DSA was used for imaging of cerebral vessels before blocking, during blocking and at 0.5 and 2 hours after ischemia perfusion. GE Signa 1.5 T supraconduction magnetic resonance imaging was used for DWI examination; in addition, PWI was used based on focal sites and areas. Otherwise, magnetic resonance imaging (MRI) was used to detect signal changes of T1WI and T2WI in ischemic areas. MAIN OUTCOME MEASURES: Analytic results of DSA, DWI, PWI and MRI. RESULTS: All 14 experimental piglets were involved in the final analysis. ① DSA: The blood flow of bilateral ascending pharyngeal arteries and its branch were blocked at blocking phase, which restored 0.5 and 2 hours after reperfusion. ② DWI and PWI: There were no observable abnormalities in PWI and DWI at pre-blocking. Abnormal increased signals were found on both DWI and PWI at during and post-blocking. There were reduction in ADC and rCBF and delay in rTTP at all time points except pre-blocking. ③ MRI: There were no abnormal signals observable at any time of pre- and post-blocking in T1WI and T2WI. CONCLUSION: It is feasible to establish this kind of animal experimental models, and it can simulate the ischemic state; meanwhile, the existence and extent can be showed directly by DSA, DWI, and PWI.

人子宫内膜植入兔眼前房模型的研究

本实验成功地将人子宫内膜植入到１５只去卵巢新西兰雌兔的眼前房，并给每只兔外源补充雌二醇（Ｅ２）１００μｇ／ｄ和孕酮（Ｐ）８ｍｇ／ｄ。在内膜植入期间每只兔皮下注射总量为９ｍｇ的霉酚酸（ｍｙ－ｃｏｐｈｅｎｏｌｉｃａｃｉｄ）以防免疫排斥反应。在眼前房的人子宫内膜存活了２８．４４±８．６５天，兔血清Ｅ２和Ｐ的平均值分别为１６１．７１±１５．１３和３８．８８±７．４５ｐｍｏｌ／Ｌ。前房液中Ｅ２和Ｐ浓度在植入人子宫内膜前后分别为２４．８０±１６．５３和１７０９．２５±４７５．１０ｐｍｏｌ／Ｌ，２．００±０．５３和１２．２２±３．８１ｎｍｏｌ／Ｌ。树脂切片验证人子宫内膜植入兔眼前房第５天就能与虹膜附贴并有血管发生。来自巩膜的血管分布在子宫内膜周围。扫描电镜观察人子宫内膜分化成分泌细胞和纤毛细胞。植入人子宫内膜后，前房液的蛋白浓度高于植入前。可以证明该模型可用来研究人子宫内膜对药物的反应和通过对前房液的测量研究子宫内膜的分泌功能。
