谣言,你也给我站住!

马克吐温:谎言跨越半个地球的时候,真相还在穿鞋.上个月的一篇读着让无数人心酸的募捐文一夜之间转遍朋友圈,当我们还在叹息孩子的不幸时,反转很快出现……真真假假的转文风波又一次消费了读者.那么关于谣言,心理学有何说法?     

早产儿及发育迟滞低出生体重儿的电生理研究

<正> 胎儿的周围神经日趋成熟和髓鞘化。作者在以往的研究中发现足月宫内发育迟滞儿(FT—IUGR)和早产儿(PT—AGA)的运动神经传导速度(MNCV)较足月儿(FT—AGA)减慢。本文中作者报道了相同体重的PT—AGA和FT—IUGR新生儿的MNCV(运动神经传导速度)和HRL(H反射潜伏期)检测结果。 43名单胎新生儿来自新生儿学和围产医学部     

百优解治疗小脑性共济失调与血小板5—HT测定

目的探讨百优解治疗小脑性共济失调的疗效和作用机制.方法接受百优解治疗的患者20例,治疗前后进行病情评分和血小板5-羟色胺(5-HT)测定,与毒扁豆碱治疗组(26例)、对照组(112例健康查体者)进行疗效对比.结果(1)百优解治疗组的疗效(70.0%)优于毒扁豆碱治疗组(38.5%)(P<0.05);(2)患者组血小板5-HT水平低于对照组,具有极显著意义(P<0.001);(3)百优解治疗前后血小板5-HT浓度改变,有效的10例有下降趋势,无效的5例明显增高.结论(1)百优解对小脑性共济失调具有肯定的疗效,与5-HT代谢缺陷得到纠正有关;(2)血小板5-HT测定可能成为小脑性共济失调诊断和疗效评估的客观化验指标.

脂肪干细胞侧脑室定向移植改善脑出血大鼠的神经功能

Objective To study improvement of neural function by stereotaxic transplantation of adipose-derived stem cells (ADSC) into lateral cerebral ventricle after intracerebral hemorrhage in rats and its mechanism. Methods ADSC were cultured and proliferated in vitro, which had been marked with Brdu for 48 h before transplantation. The rat caudate nucleus hemorrhage (ICH) models were divided into 2 groups. ADSC were stereotaxically transplanted into the right lateral ventricles in ADSC group, and equal volume of saline was transplanted into control group. The score of neurological behavior were evaluated at modeling and 1, 3, 7, 14, 28 days after transplantation respectively.Double-staining immunofluorescence technique was used to detect Brdu-positive cells and the differentiation of neurons and astrocytes. In accordance with the instructions of TUNEL kit, cell apoptosis, and the expression of VEGF and angiogenesis were assayed. Results In vitro ADSC expressed undergo osteogenic and adipogenic differentiation. Compared with the control group, ADSC group had better motor function at 3, 7, and 14 days (P＜0. 05). Double-staining immunofluorescence showed mostly grafted Brdu-reactive ADSC had migrated to the hematoma zone, and some survivedand expressed Neun of Gfap. TUNEL analysis revealed that, 3 days after transplantation, the number of apoptotic cells in ADSC group was significantly less than in the control group (P＜0. 05). Three days after transplantation, VEGF expression levels in ADSC group were significantly higher than in the control group (P＜0. 05). Conclusion ADSC stereotaxially transplanted into the lateral ventricle can survive and differentiate into neuron-like cells. ADSC transplantation may reduce apoptosis and secret VEGF to promote the angiogenesis, and improve neural functional in intracerebral hemorrhage rats.     

高血压脑出血微创术前后脑干听觉诱发电位监测

目的；观察高血压脑出血患微创术前后脑干听觉诱发电位（BAEP）变化，评价微创术疗效。方法：对36例高血压脑出血患进行微创术治疗，监测术前、术后24、48、72h以及术后第7天的BAEP改变。结果：本组存活30例，6例死亡，死亡率16．7％。术前BAEP异常主要表现为潜伏期（PL）及峰间潜伏期（IPL）延长，与正常对照组相比有显差异（P＜0．05）。术后24h内复查，PL和IPL均有明显下降，与术前相比，有显差异（P＜0．05）。术后48h、72h、7天复查BAEP，与术前相比，PL和IPL虽然下降，但无明显统计学差异（P＞0．05）；与正常对照组相比，PL和IPL仍有延长（P＜0．05）。结论：微创术安全、有效。BAEP可用于高血压脑出血患微创术前后监测及预后评价。BAEP可作为急性缺血、缺氧时脑干功能的一个检测指标。

听神经瘤的术前电生理检查

<正> 听神经瘤是最常见的桥脑小脑角肿瘤。病程早期很少发现面神经受累的临床征象,然而面神经受压却是术中的常见改变。许多作者证明电刺激诱发的眨眼反射有益于评估面神经、三叉神经及脑干的功能,眨眼反射(三叉神经-面神经反射)的研究可显示亚临床功能障碍的存在与否。但是,眨眼反射对有些病例不能确定反射弧受损的平面。作者结合面神经传导及下颌反射检查了20例经CT 诊断、手术证实的听神经瘤患者。所有病例均无三叉神经和脑干
