（mRS评分≤2分）等。
结果 共纳入13例患者，平均年龄58.7±14.5岁，男性11例（84.6%）。术后血管成功再通率100%；围
手术期并发症2例，假性动脉瘤1例、无症状性颅内出血1例；90 d良好预后率100%。
结论 急性大血管闭塞性轻型卒中行血管内治疗可能是安全、有效的。     

食管鳞癌中肿瘤微血管密度的临床意义

目的　研究分析食管癌组织中肿瘤微血管密度 (MVD)的临床意义。方法　采用免疫组化的方法检测4 5例食管鳞癌根治性切除术后的肿瘤组织中的肿瘤微血管密度 ,应用SPSS统计软件分析肿瘤MVD与食管鳞癌临床病理参数及预后的关系。结果　本组病例中 ,肿瘤MVD平均值为 15 .5 8,中位值为 15。MVD水平与食管癌的肿瘤局部浸润程度、区域淋巴结转移及TNM分期有关 (P <0 .0 5 )。多血管型 (MVD >15 )病例的术后生存率低于少血管型 (MVD≤ 15 )病例 (P =0 .0 2 78)。Cox比例风险模型证实MVD水平是食管癌根治性切除病人预后的独立预测指标。结论　食管鳞癌的血管新生与癌肿进展程度有关 ,高MVD的食管鳞癌患者术后生存率明显低于低MVD的患者 ,其MVD水平可独立用于预测食管癌根治性切除病人的预后

The action of(±)-MDMA on medial prefrontal cortical neurons is mediated through the serotonergic system

The mechanism of action of systemitically administered(±)-MDMA (3, 4-methylenedioxymethamphetamine) on spontaneously active neurons in the medial prefrontal cortex (mPFc) of chloral hydrate anesthetized rats was examined using standard single unit extracellular recording techniques. Intravenously administered MDMA dose-dependently decreased the firing rates of the majority of mPFc neurons in control rats. In contrast, in rats that were pretreated withp-chlorophenylalanine (PCPA), which depletes the brain serotonin (5-hydroxytryptamine, 5-HT) content by inhibiting tryptophan hydroxylase, the rate-limiting enzyme in the synthesis of 5-HT, MDMA was largely ineffective in inhibiting the firing of mPFc cells. In PCPA-treated animals, the administration of 5-hydroxytryptophan (5-HTP), which presumably restored the brain 5-HT content, but notl-DOPA, reinstated MDMA's inhibitory action in PCPA-treated rats. In rats that were pretreated withα-methyl-p-tyrosine (AMPT), which depletes the brain dopamine (DA) content by inhibiting tyrosine hydroxylase, the rate-limiting enzyme in the synthesis of DA, MDMA inhibited the firing of all of the mPFc cells. MDMA's effect on mPFc neurons was reversed by 5-HT receptor antagonists such as granisetron and metergoline. These results strongly suggest that MDMA exerts its action on mPFc cells indirectly by releasing endogenous 5-HT.

Closure of left ventricle perforation with the use of muscular VSD occluder.

Growing experience in interventional cardiology leads to the use of large diameter of vascular equipment. In some instances, the so-called hybrid procedures are performed. After performing the interventional procedure, the opening in ventricular wall is closed surgically. Our intention was to check if the MVSDO can be used to close the perforation in the heart after the interventional cardiology procedure performed through the left ventricular (LV) free wall. In three pigs under general anesthesia, the heart was exposed through a small substernal incision. The LV was punctured and an 18F sheath was introduced into the LV. A 14 mm MVSDO was inserted through the 10F Delivery System. Using both the echocardiographic and angiographic guidance, the MVSDO was placed on the LV wall to close the opening in the LV. Time and volume of bleeding was recorded. In all cases the occluder was successfully placed closing the opening, bleeding observed after deployment of occluder lasted for approximately 2 min. We think MVSD occluder can be used to close the LV free wall perforation after hybrid interventional cardiac procedure. Early bleeding through MVSDO might be resolved by the manufacturing of new occluder with better sealing properties.
