观察改良线栓对总体手术时间、术中颈总动脉血流阻断时间、线栓误入翼腭动脉几率和模型成功率的影响，并通过神经行为学评分、红四氮唑染色和磁共振检测等方法评价该模型的稳定性和可靠性。

Results The bletilla colloid was a homogenous viscous colloid whose relative viscosity was 2324.6 mm2/s. It was easily injected through 4-F catheter and hyperattenuating under fluoroscopy, meanwhile, with good histocompatibility and hemo-compatibility, without pyrogenetic response and toxicity. In vitro, the mixture of bletilla colloid and MMC did not produce separation and suspention phenomena but released 50%of MMC at 1.8h and 100%at 3.4h. The bletilla colloid mainly embolized peripheral arteries, maintaining occlusion for 5 weeks and without formation of collateral circulation. The injuries of normal hepatic tissues were slight, without hepatic cytonecrosis.

结果 (1)白芨胶为一种均质的胶状物，有一定粘滞性，相对粘度2 324.6 mm2/s，不透X线，易经4F导管注射；(2)白芨胶具有良好的血液相容性和组织相容性，无致热原性及毒性作用；(3)白芨胶-丝裂霉素C体外混合后，无分层及悬浮现象，释放MMC 50%约需1.8小时，100%需3.4小时；(4)白芨胶主要栓塞末梢小动脉，栓塞牢靠，维持时间可达5周，不易形成侧支循环；(5)白芨胶栓塞对正常肝组织损伤轻微，未出现肝细胞坏死。

Objective:To study the relationship between resting heart rate and repatency rate in patients with coronary chronic total occlusion.

目的：了解静息心率与冠状动脉慢性完全闭塞病变经皮冠状动脉介入术成功率的关系。

RHR can effecting the coronary repatency rate of PCI in patients with chronic total coronary occlusion,the more lower RHR, the more higher repatency rate.Author′s address:Department of Cardiology,Guilin People Hospital,Guilin,Guangxi,541000,China

After careful assessment of the potential cause of treatment failure, retreatment with ERFT was successful in all cases, resulting in persistent occlusion.

在仔细评估治疗失败的原因后，再以ERFT治疗，所有病例均成功地造成持续的封锁。

ABSTRACT Direct intrahepatic portacaval shunt is created between the retrohepatic IVC and portal vein intrahepatically, with partial portal flow shunted directly to the IVC. DIPS can eliminate the defect that the outflow vein—hepatic vein is vulnerable to stenosis or occlusion after TIPS.

直接性门腔分流是在肝后段下腔静脉与门脉之间建立肝内分流，将部分门脉血液直接分流入粗大的下腔静脉，解决了TIPS术后分流道引流静脉——肝静脉易狭窄或闭塞的缺陷。

In this study, we use the Computer Aided Axiography recorded condyle movement of 39 normal occlusion, during mandible open and close, protrusion and retrusion, and medio-free movement, in order to find out the normal condyle movement style and range.

本研究选用髁突轴图描记仪(Computer Aided Diagnosis Axiography)对39名正常〓的髁突运动予以记录，记录下颌在开闭口，前伸后退和侧方运动时的髁突运动情况，确立正常功能状态下双侧颞下颌关节运动形式及范围。

Most Angle class two division one subdivision malocclusion with mandibular retrusion have their characteristic condylar movement style, the difference from that of normal occlusion maybe correlate to condylar position, overbite and overjet.

下颌后缩型安氏Ⅱ类1分类错牙合的髁突运动轨迹有较典型的特征，可能与其髁突位置、前牙覆牙合覆盖有关。

In this study, we use Computer Aided Diagnosis Axiogragh recorded condylar movement of normal occlusion and Angle class two division one subdivision malocclusion with mandibular retrusion every twenty-five during mandible open and close, protrusion and retrusion, and medio-free movement. Then we analysis the deference in order to find out the characteristic of condylar movement of Angle class two division one subdivision malocclusion with mandibular retrusion and the change regularity among befor and after functional appliance treatment.

本研究以正常牙合和下颌后缩型安氏Ⅱ类1分类错牙合各25名为研究对象，采用髁突运动轨迹轴图描记仪(Computer Aided Diagnosis Axiogragh)记录其下颌在开闭口、前伸后退和侧方运动时髁突的运动情况，对比分析下颌后缩型安氏Ⅱ类1分类错牙合的髁突运动轨迹特征及其功能矫治前后髁突运动轨迹的变化。

METHODS Rats were pretreated with rutaecarpine 10 min before the experiment, and then the left main coronary artery of rat hearts was subjected to 60-min occlusion followed by 3h reperfusion.

大鼠在实验前10 min静脉注射吴茱萸次碱，然后结扎冠状动脉左前降支60 min，再灌注3 h。
