摘要: 目的探讨电刺激小脑顶核对缺氧缺血脑损伤(HIBD)新生大鼠睫状神经营养因子(CNTF)蛋白及学习记忆功能的影响。方法将大鼠随机分为假手术组、模型组和电刺激组,每组又分为7d和14d2个亚组,每个亚组6只。采用结扎左侧颈总动脉并吸入氮氧混合气体2h制作新生大鼠HIBD动物模型,电刺激组于造模后第2天开始电刺激治疗,强度25mA,频率5Hz,20min/次,每天2次。分别于干预后7d、14d用Y-型迷宫检测。HE染色法光镜下观察脑神经细胞和神经纤维的病理变化,免疫组化检测脑组织CNTF蛋白水平的表达。结果电刺激组总反应时间明显短于模型组(P<0.01),主动回避率及正确反应率均明显高于模型组(P<0.01),皮质及海马周围CNTF蛋白面积与积分光密度值较模型组增多(P<0.05)。结论电刺激小脑顶核可以提高脑组织CNTF蛋白水平表达,促进脑损伤大鼠学习记忆能力的恢复。

Abstract: Objective To explore oropharyngeal swallowing disorders with videofluoroscopic swallowing study (VFSS). Methods 16 patients with dysphagia accepted VFSS with 10 ml of thin barium meal (50% w/v), thick barium meal (270% w/v), biscuit coated with thick barium meal in single swallow. Their swallowing function was observed on the lateral and anterior/posterior planes, including: symmetry of pyriform sinuses, oral transit time, presence of pharyngeal delay, pharyngeal transit time, oral and pharyngeal residue, and presence of aspiration.Results 5 patients demonstrated oral swallowing disorder. 3 patients demonstrated pharyngeal swallowing disorders, that was pharyngeal delay which caused in aspiration after swallowing. 8 patients demonstrated oropharyngeal swallowing disorders, and 3 of them presented aspiration,2 patients were silent aspirators, 1 was aspiration before and 1 after swallowing. The aspiration time could not be judged from the videofluoroscopy in the other one. For 4 patients with aspiration, 3 were severe, with more than 25% of the bolus aspirated, and 1 aspirated less than 5%. Conclusion VFSS can be helpful to plan individual rehabilitation.
