The immunocytochemistry was used to identify the RASMC.RESULTS: The RASMC were successfully cultured by the adherent method of tissue explants and grown in the "peak- valley" mode. The cultured RASMC were fusiform shape with a big oviform or round nuclei rich in cytoplasm. Immunohistochemical method ( S-P method) showed strong expression of a- smooth muscle actin.

结果：组织块贴壁法成功培养出SD大鼠胸主动脉平滑肌细胞，培养的细胞呈典型&峰-谷&样生长，HE染色细胞呈梭形，胞浆丰富，核大而圆或椭圆，免疫组化S-P法检测a-平滑肌肌动蛋白单克隆抗体呈强阳性表达。

Preliminary data on speech effect of STN-DBS on five Chinese Parkinsonia patients were demonstrated. Inconsistent outcome of the performance suggests that future study should include subject selection criteria such as with/ without medication, longterm effects, as well as larger sample size.

本研究提供国内视丘下核深部脑刺激手术对巴金森氏症患者言语成效初步数据，虽然五名患者在言语运动轮替、构音位置与强度、口语流畅度、嗓音功能呈现不同程度改善状态，但是患者间表现差异大，未来研究需考量病患条件与分类，术后时间一致性、药物使用、大样本等因素。

The intracellular expression of viral gene and phenotypical change of transformants were examined.

结果：分离获得了可长期体外培养的SV40转化细胞克隆，已传23代以上，体外存活超过250d；DNA印迹实验显示SV40大T基因已整合至细胞染色体内，间接免疫荧光检测示多数细胞胞核内有大T基因产物的表达；转化细胞对裸鼠无致瘤性，并可正常表达角蛋白。

Methods Bilateral NBM of elderly rats were damaged by quinolinic acid,and the AD model was established.The single passive aviodance stepdown training and watermaze spatial localization test were used to study the effects of Ginsenoside Rg1 on learning and memory of AD rats.

应用喹啉酸损毁老年大鼠双侧Meynert基底核，制备AD模型，通过被动回避跳台实验和水迷宫空间分辨能力测试，研究人参皂苷Rg1对AD大鼠学习记忆能力的影响。

In the basal ganglia, internal and external capsule, corona radiata, centrum semiovale, periventrical, the incidence rates of HSIs in hypertensive patients aged from 60-69 were greater than that of the group with normal blood pressure P""

高血压患者多在60～69岁时表现明显脑损害；慢性高血压大鼠直到鼠龄较大时，尾壳核区域出现明显的病理改变，才在MRI上显示出来。

The unilateral hypertrophy of the striae medullares is correlated with thehypertiophy of the contralateral nucleus arcuatus.

一侧偏大的髓纹与对侧弓状核的偏大是相繋的。

Methods: A rat chronic gastric ulcer model was made by infecting Hp(NCTC11637 strain)after injecting acetic acid into the subserosa of the stomach. In the experiments, the techniques of immunohistochemical stain and in situ hybridization etc. were used to observe the expression of bFGFmRNA and PCNA in th ulcer.

采用幽门螺杆菌多次重复感染乙酸性胃溃疡大鼠，造成Hp相关的慢性胃溃疡模型，运用免疫组化和原位杂交等技术观察该方对Hp感染的慢性胃溃疡大鼠胃黏膜碱性成纤维生长因子mRNA和胃黏膜细胞增殖核抗原的影响。

SUMMARY A more accurate steady drillstring tension-torque model has been established by taking into account of drillstring, wellbore condition , drilling operation and drilling parameters. This model has been used in scientific calculations of directional and horizontal wells, such as determing the friction factor between wellbore and drillstring, calculating the hook load and rotating torque, ckecking the strength and stability of drillstring, optimizing well trajectory, computing the WOB while drilling by downhole motor and predioting the maxinum allowable length of horizontal section.

综合考虑钻柱、井眼环境、作业过程和作业参数的影响，建立了更完善的钻柱稳态拉力和扭矩模型，并将其应用于确定钻柱与井壁的摩擦系数、计算大钩负荷和转盘扭矩、校核钻柱的强度和稳定性、优选井眼剖面、推算井下动力钻进的实际钻压和预测水平井段的最大可钻长度等定向水平井的科学计算中。

Methods: AD rat model was established by microinjection of amyloid-beta protein (Aβ1-40) into the Meynert nucleus of rats. We acupunctured "baihui (DU 20)""taixi (KI 3)""zusanli (ST 36)" to observe the effect of electrotherapy on AD rats, the memory ability was studied by Morris water maze, and ultrastructure of neurons was observed under transmission electron microscopy.
