The optimal reconstruction windows of patients with stable HR(≤75 bpm and≥91 bpm) were concentrated in 71%,ranged from 65%-80%, and in 41%,ranged from 32%—50%,respectively.The prospectively ECG-gated DSCT coronary angiography can be used in patients with stable HR(≤75 bpm and≥91 bpm) in abstract.②To explore the clinical application of prospectively ECG-gated transverse DSCT coronary angiography.Methods Two hundreds patients[Body mass index:23-25 kg/m~2,122 patients(average HR≤75 bpm),78 patients(average HR≥91 bpm)]with suspected or known coronary artery disease underwent prospectively ECG-gated transverse DSCT coronary angiography,among them,30 patients underwent selectively coronary angiography,grouping them into 2 groups according to the average HR of scanning.Group A(17 cases,HR≤75 bpm),group B(13 cases, HR≥91 bpm),the DSCTA results were compared with SCAG.Then,calculate the accuracy of patients in each group and evaluate the agreement of accuracy between DSCTCA and SCAG by Kappa statistics.

方法回顾性分析200例行适应性前瞻性心电门控双源CT冠状动脉血管成像的患者(排除扫描过程中，屏气配合差，出现心律不齐的患者及行支架置入或搭桥术后复查的患者)，包括屏气时平均HR≤75 bpm患者122例，HR≥91 bpm患者78例；其中30例同期行选择性冠状动脉血管造影，按屏气时HR将其分为2组，A组17例：HR≤75 bpm，B组13例：HR≥91 bpm，分别与金标准SCAG对照，计算2组患者的阳性诊断准确率，应用SPSS 13.0统计学软件，利用Kappa检验比较每组患者的2种诊断方法诊断结果的一致性，利用两样本率x~2检验，比较2个心率组间的诊断准确率有无明显统计学差异，并计算此30例患者的平均有效辐射剂量。

Electro-acupuncture could lower abnormally-increased plasma t-PA、PAI-1 amount, advance activity of rats blood fibrinolytic system, protect integrality of vascular endothelial cell, promote thromb elimination, relieve chronic angiospasm, improve collateral circulation, enhance recovery of ischemic and semidarkness region, consequently protect the brain tissue from injury.

电针能降低急性脑梗死大鼠血浆异常升高的t-PA及PAI-1含量，提高大鼠纤溶系统的活性，保护血管内皮细胞的完整性，促进机体清除血栓、缓解慢性血管痉挛、改善侧枝循环，促进缺血区及半暗带的恢复，从而发挥脑保护作用。

Five rats in both groups were executed at 3, 7, 14, and 28 days after model establishment. RNA was extracted from the same site of left anterior wall, and the polymerase chain reaction was used to semiquantitatively analyze the Ang1 and Tie2 receptor mRNA expression with GAPDH gene as internal control; meanwhile, the immunohistochemistry was used to detect vascular density in and around infarction area.

于术后3，7，14，28 d 四个时间点，每组取5只处死，取心脏左室前壁同一部位，提取总RNA，用RT-PCR的方法，以GAPDH基因为内参，进行半定量分析检测正常心脏及梗死后血管生成素1及Tie2 mRNA的表达；同时用免疫组化的方法检测各时间点梗死区域以及梗死周边区域血管数量。

Because of the great vessels from the surrounding to the center vertical separation of the small blood vessels such as the spoke-like arrangement, renal arteriography this diagnosis has special value.

由于大血管由周围向中心垂直分出小血管如轮辐状排列，肾动脉造影对此病诊断有特殊价值。
