In the experimental study section, the rats were divided into four groups, including the normal control, the model, the Piracetam, the QPC, and copied to AD model. After the treatment, we observed the effects on the AD rats' ability of leaning and memorizing, detecting the TChE activity in whole blood and the expression levels of the related biochemical indicators of As includeing GFAP、NGF and BDNF of the AD rats' brain hippocampus, then compared the QPC with other groups to reveal the mechanism of action of the QPC treating AD to bright.

在动物实验部分，我们通过塑造AD动物模型，设立正常对照组、模型组、脑复康组和强脾益智胶囊组，观察强脾益智胶囊对AD模型大鼠空间学习记忆能力的影响，检测AD大鼠全血、海马匀浆液中乙酰胆碱酯酶活性和通过免疫组化的方法检测胶质纤维酸性蛋白、神经生长因子、和脑源性神经营养因子的表达情况来反映星形胶质细胞的增值情况，以期揭示强脾益智胶囊对AD的治疗作用机理。

Methods: 24 SD rats were randomly divided into four groups: sham operation group, AD model group, AD model+fibroblasts transplantation groups, AD model+NT4-fibroblasts transplantation group. AD models were made by transecting bilateral fimbria-fornix.

24只雌性SD大鼠随机分为4组：假手术组、AD模型组、AD模型+成纤维细胞移植组和AD模型+NT-4-成纤维细胞移植组。

Objective: This study investigated olfactory function disorder in Canadian potential AD patients through measuring the detection threshold and recognition threshold, of the potential AD patients and the matched controls by Five Odorants Test; and evaluated whether the senile plaques, neurofibrillary tangles and neuropil threads , which were the typical pathological changes of AD, presented in the olfactory mucosa of potential AD patients.

老年性痴呆中有75%为阿尔茨海默病(Alzheimer's disease， AD)，AD 是一种神经细胞退行性疾病，原因不明，临床以进行性记忆丧失和后天获得的知识丧失，病程逐渐发展直至完全丧失生活能力为特征。其病因是多原性的。尽管AD 的描述已达90 年之久，但要在早期检出此病仍是一个难题，所以，改进其临床诊断程序、途径非常重要。当今广泛用于AD 诊断的诸多标准中均未明确提及嗅觉的改变，然而众多国外文献资料表明，几乎所有的AD 患者发病早期甚至在临床前期即表现嗅觉识别阈的改变，可见对此深入研究有助于AD 患者的早发现、早诊断。
