Just under this background, studying on the flight mechanism of flapping-wing MAV and sample fabrication from the bionics are conducted in this dissertation. The kinematics equations of insect wings can be acquired by the observation and measurement on the natural insect in researching paper. The geometry model of insect is established by UG technology. The three dimensional grid during the insect moving in the flow field is achieved which adopted grid generation method. The characteristic of lift and drag are attained by simulation the surround flow field during the locomotion of wings, and the flight mechanism of insect is discussed. Based on this study, the physical flapping-wing MAV is fabricated by the acquirable materials and parts of apparatus in existence.

Objective To observe the pathological changes and investigate the hepatocyte apoptosis relating with CYP2E1 in alcoholic liver diseaseof rat. Method the Model of Alcoholic liver Disease: Rats were randomly divided into model group(n=37)and control group(n=33). The dose of 40％ethanol was administerd at 8g/kg body weight by garage twice daily for 8 weeks in model group, and control group was received isovolume saline by gavage. End of 8th week, the activities of serum ALT and AST were detect by autobiochemistry instrument. The pathological changes of liver was observed under light microscope after HE staining, hepatocyte apoptosis was detected by the TUNEL method.

目的： 研究酒精性肝病细胞凋亡程度与细胞色素P4502E1表达的关系方法：用酒精灌胃法制备大鼠酒精性肝病模型，将70只wistar大鼠随机分为正常对照组(33只)和酒精灌胃组(37只)，连续灌胃8周后病理切片观察细胞凋亡程度，干化学法测定ALT、AST的含量变化，用PCR法测定细胞色素P450 2E1的表达变化。

Apical aneurysms varied considerably in size (maximum dimension, 10 to 66 mm), were dyskinetic/akinetic with thin rims, and were associated with transmural myocardial scarring identified by late gadolinium enhancement cardiovascular magnetic resonance. Apical aneurysms were recognized by echocardiography in only 16 of 28 patients (57%) but by cardiovascular magnetic resonance in the 12 patients undetected by echocardiography.

心尖部室壁瘤大小不一（最大直径：10-66mm），有一圈活动差/不能运动的边缘，以及后来被增强心血管核磁造影证实有透壁性心肌疤痕。28名患者中仅有16（57%）人为彩超确诊，彩超漏诊的12人由心脏核磁共振确诊。

ABSTRACT］ Objective To study the pharmacological effects of oral medical ice and to provide for its evidence for clinical application. Methods The anti-inflammatory effect of OMI was determined on three inflammatory models: swelling of mice ear induced by dimethylbenzene, hind paw edema and back granuloma caused by hypodermic injection of agar in rats. The an- algesic action of OMI was studied by observing the mice's reaction to the heat simulation. The effect of OMI on bleeding time was tested by tail-cutting method.

Titanium plate first was cleaned by glow Discharge using argon plasma to eliminate surface contaminants and to produce a consistent and reproducible titanium oxide surface layer. Then an intermediary allylamine deposition was covalently linked to the oxide layer by glow discharge, followed by the covalent binding of albumin to the free terminal NH2 groups using glutaraldehyde as a coupling agent. Surface morphologies were observed by scanning electron microscopy and atomic force microscopy.

The results shown that:(1) Bufo raddei Strauch tadpole was capable of lens regeneration, which originated from the epithelial cells at dorsal iris margin by depigmentation.(2) Depigmentation of Bufo raddei Strauch during lens regeneration was by two methods: First, pigment granules initially dispersed all over the cytoplasm were moved towards the periphery of the cell, and then were directly taken up by the amoeboid cells. Second, pigment granules in a cell were first crowded in a mass, surrounded by a membranous structure in the cytoplasm, which were eventually discharged as a mass from the cell.
