The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

应用二维超声心动图在胸骨旁左心室长轴观测量左心室舒张末期内径、室间隔和左心室后壁舒张末期厚度，采用Teichholtz公式计算左心室射血分数，采用Devereux校正公式计算左心室心肌质量，左心室心肌质量指数=左心室心肌质量/体表面积；在心尖四腔心和心尖两腔心切面，应用组织多普勒成像获取室间隔、左心室侧壁、前壁和下壁的基底段和中间段8个心肌节段沿左心室长轴运动的速度频谱，测算左心室局部心肌松弛不同步性指数(regional left ventricular relaxation asynchrony index， AI)；在心尖四腔心切面，应用彩色M型多普勒超声心动图测量左心室舒张早期血流传播速度。

Analyzing the relation between earthquake and structure distortion, main fault belt, crust, upper mantle, ground fracture, hotspring, geotherm, conductance frame, stress state in Guanzhong area is analyzed with earthquake mechanism, isoseismal line, crustal stress measure, fault displacement measure, and simulating test results. Earthquake formation mechanism is discussed with dynamics mechanism in Guanzhong base. There are 3 forces and a good medium environment, which are main reasons caused earthquake happened in Guanzhong area. The first force is NE and NEE level extrusion one which is parallel with long axis of Guanzhong base. The second one is level strain which is vertical with long axis of the base.

对地震与构造形变、主要断裂带、地壳及上地幔、地裂缝、温泉和地热、电性结构等关系进行了分析研究，通过震源机制解、地震等烈度线、地应力测量、断层位移测量及模拟试验等成果，分析了关中地区的地应力状态，从关中盆地的动力学机制，对该区的地震成因机制进行了探讨，认为与关中盆地长轴平行的NE和NEE向的水平挤压力、与盆地长轴方向垂直的水平张力及地幔上涌力三组力的作用，加之壳内高导层这一有利的介质环境，是导致关中地区地震发生的主要原因。

Results: Both sides of elder hernia sac became constrictive because of fibrosis caused by A ring, C ring chronic inflammation, which made hiatal hernia sac dilate like a expanded balloon, 7 cases were manifested stenotic at the two ends. Lithiasis in the hiatal hernia sac display of filling defect the same as the smoothly sac without aerogenic powder. Long axis of filling defect were accorded with that of esophagous, the sign could be described as "cast mould" of esophagous hiatal hernia sac.

结果：由于老年性疝囊两端的A环、C环在长期慢性炎症的刺激下纤维化而狭窄，使疝囊膨胀表现为&吹气球征&，7例疝囊上下两端狭窄。7例疝囊内结石未服用产气粉前表现为与疝囊同等大小且边缘光滑的充盈缺损，充盈缺损的长轴与食道长轴方向基本一致，呈现&食管疝囊铸型征&。

Observation using transmission electron microscopy found the irreversible centripetal movement of chloroplasts in chlorotic plants, as a result occurred in three sequential events:(1) chloroplast positions changed from face position (with long axis of chloroplasts at the cell walls perpendicular to light ray) to profile position (with long axis chloroplasts near the cell walls parallel to light ray),(2) chloroplast shapes changed from long elliptical to circular,(3) chloroplasts were separated from the cell wall and moved to the center of the cell.
