川芎嗪对脑缺血再灌注损伤后细胞粘附作用的影响

背景:大脑缺血区白细胞与内皮细胞的活化及表面粘附分子的表达可使白细胞聚集浸润,发挥细胞毒作用进而使脑损伤加重。中药川芎嗪具有抗血栓形成,改善微循环的作用。目的:观察川芎嗪对脑缺血鄄再灌注损伤后局灶区白细胞与内皮细胞粘附性变化的影响。设计:随机对照动物实验。单位:第三军医大学大坪医院脑血管病二科,玉溪市第二人民医院精神科。材料:实验于第三军医大学大坪医院脑血管病二科实验室完成。雄性Wistar大鼠32只,体质量250～300g,随机分为3组,8只为正常对照组,12只为脑缺血鄄再灌注组,12只为脑缺血-再灌注加用川芎嗪组。方法:川芎嗪组静脉注射磷酸川芎嗪注射液(15g/kg)。正常对照组及脑缺血组予静脉注射等量生理盐水。通过免疫荧光标记技术和显微超高速录像系统观察脑缺血-再灌注及应用川芎嗪后局灶区白细胞粘附性的变化。主要观察指标:①脑缺血鄄再灌注损伤局灶区微动脉白细胞附壁密度指数及白细胞与内皮细胞之间黏附力。②应用川芎嗪后局灶区白细胞粘附性的变化。结果:实验动物全部进入结果分析。①与对照组比较,脑缺血鄄再灌注损伤组局灶区微动脉白细胞附壁密度指数增大,白细胞与内皮细胞间断裂应力明显下降,粘附力显著增强,差异均有显著性(P<0.01)。②与脑缺血鄄再灌注损伤组比较,川芎嗪治疗组白细胞附壁密度指数及粘附力显著下降,至24h后降至较低水平,断裂应力增高,至24h与正常对照组差异无显著性,并维持在较高水平。结论:川芎嗪可显著减轻脑缺血鄄再灌注损伤后内皮细胞与白细胞的粘附。

2007年西藏自治区碘缺乏病高危地区重点人群调查分析

Objective To propose prevention and control strategy against iodine deficiency disorders to prevent new cases of endemic cretinism from occurring. Methods In April and August 2007, all the suspected cretinism patients born after the first of January, 1997 were searched for in 16 counties from Lhasa, Shannan, Nyingchi, Qamdo and Xigaze. Meanwhile, 60 children aged 8-10 years were selected in each of the two rural villages of each county chosen. Goiter was examined using palpation and B-ultrasound, urinary iodine was determined, inteligence quotient(IQ) was tested; 30 women of childbearing age from each village chosen underwent urinary iodine test and household salt semi-quantitative detection. Results No new cases of endemic cretinism had been found; Palpation identified goiter at 4.5% (257/5680) in children, B-ultrasound revealed a rate of 4.7% (258/5433). Median of urinary iodine was 159.4 μg/L, the averaged IQ was 78.3±14.5; women of childbearing age had a median urinary iodine of 70.2 μg/L. The coverage rate of iodized salt was 52.8%. Conclusions Goiter rate in children, urinary iodine level meet the standard set for the elimination of iodine deficiency disorders; however, the low IQ children, low coverage of iodized salt and the level of urinary iodine in women of childbearing age are less than desirable. Iodine deficiency disorders prevention and control need to be strengthened.     

脑血管造影后皮质盲三例

皮质盲是脑血管造影罕见的并发症,其病因尚不十分清楚。普遍认为,动脉造影后皮质盲与对比剂通过枕叶的血-脑屏障而导致枕叶脑细胞损害有关,该损伤较轻微,往往为可逆的[1-2]。内蒙古医学院附属医院自1997年1月至2006年4月共行全脑血管造影600例,出现明显视力改变者3例(0.5%)。将结果报道如下。1病例资料本组患者均在局部浸润麻醉下,采用Seldinger′s技术,行股动脉穿刺。穿刺后经股动脉鞘注入3000U肝素盐水。常规双侧颈总动脉及一侧或双侧椎动脉置管正侧位投照,必要时颈内、外动脉分别投照及旋转数字减影血管造影(DSA)。所用对比剂为碘海醇(…

体外细胞转化系统在预防医学致癌因子检测中的应用

据估计人类的肿瘤约85～90%以上是由环境因子所致,其中包括物理、化学和生物等有害因子。这些因子可通过吸入和食入等方式作用于人体,诱发肿瘤。尤其在工业社会中,环境质量的恶化,使自然环境中各种因子改变,有害因子增加,这是当今社会对人类致癌作
