The reasons for these complications: The main arteries as a result of high blood pressure resulted in a series of changes, especially the long-term systemic small artery spasm, may cause the vessel wall occurred in dystrophic changes in subintimal deposition of protein substances, fibrous tissue increased , in the muscle membrane hypertrophy, reduced arterial elasticity, resulting in luminal narrowing.

产生这些并发症的原因：主要是由于高血压使动脉产生了一系列变化，尤其是全身小动脉的长期痉挛，可能使血管壁发生营养不良性变化，内膜下蛋白性物质沉积，纤维组织增多，中膜肌层肥厚，动脉弹性减低，以致管腔变窄。

RESULTS: A total of 36 rabbit models, 6 in the 1-month therapy group and 8 in the 3-month therapy group were died from infection. In the 1-month therapy group, thick ureteric wall and smooth ureteric lumina developed without any contracture. Under the optical microscope, transitional epithelial cells covered throughout the inner walls and smooth muscle cells appeared sparsely in a mussy configuration. In addition, CKAE1/AE3 staining was positive butα-actin staining was very weak when checked by immunohistochemistry. In the 3-month therapy group, amnion-ureters were enclosed by their peripheral tissue and showed rich blood vessels and normal ureteric lumina without significant contracture, futher more, there had formed a well-arranged transitional epithelial layer and smooth muscular layer, the immunohistochemistry result showed that the expression of CKAE1/AE3 and α-actin were positive.

结果：36只大白兔中，1个月治疗组死亡6只，3个月治疗组死亡8只，死亡原因均为感染。1个月治疗组大白兔羊膜输尿管柔软，长4 cm，管壁变厚，无挛缩，移行上皮组织爬满内壁，平滑肌组织部分再生，但较稀疏，排列不规则；免疫组织化学检查提示CKAE1/AE3染色阳性，α-Actin染色微弱。3个月治疗组大白兔羊膜输尿管与周围粘连，有丰富的血运，无明显挛缩，管腔不缩小，已形成良好的移行上皮层和平滑肌层，免疫组织化学显示α-Actin和CKAE1/AE3染色均为阳性。

The surface temperatures of the radioisotope target capsule is one of the important parameter to its structure integrity.

放射性同位素辐照靶件在堆内辐照过程中能否保持其完整性，受到诸多因素的影响，其中辐照靶件包装容器外壁温度和内腔温度是辐照安全的重要参数。

Results Among all 25 cases of lymphangioma,Within 20 cases of cystic lymphangioma,single cyst was showed in 14 cases and multilocular cyst was showed in 6 cases in plain scan,and little enhancement of capsule wall and septal in 8 cases in enhancement scanning. Cystic-solid mass was showed in 4 cases of cavernoma lymphangioma in plain scan,and solid part of mass was enhanced obviously in enhancement scanning.1 capillary ymphangioma showed the skin and hypodermic thicking,and part of area showed little beehive-like feature. Enhancement scanning showed slight irregularity enhancement.

结果 25例淋巴管瘤中20例囊性淋巴管瘤，CT平扫14例表现为单一囊肿，6例表现为多房性囊肿，囊腔内见有分隔；增强扫描8例出现囊壁或间隔的轻微强化。4例海绵状淋巴管瘤平扫均表现为囊实性肿块，增强检查实性部分有明显分期增强；1例毛细管型淋巴管瘤表现为局部皮肤及皮下组织的增厚，部分区域见有小蜂房样表现，增强扫描见有轻度不规则强化。

Such an exudative process is typical for bacterial infection.

在高倍镜下，可见肺泡腔内渗出液的主要成分是中性粒细胞，肺泡壁毛细血管扩张充血，这种渗出过程是典型的细菌性肺炎。

3Wood basic density had a significant, negative genetic correlation with tree volume and tracheid length, and had no significant correlation with tree height, diameter at breast height, ratio of length to width and ratio of cell wall to cavity.

3基本密度与树高、胸径、管胞长宽比、壁腔比无显著遗传相关；与材积、管胞长度有显著的负遗传相关。

For many reasons, such as material, wall thickness, rigidity, clamp etc, during the course of treatment,assemblage and inventory,thin-wall rectangular deep recessed parts tend to generate distortion ,which induces increment of the processing technic establishing difficulty.

由于工件材料、壁厚、刚性、装夹等多种原因，薄壁矩形深腔体零件在加工、装配及库存过程中极易产生变形，导致编制零件加工工艺的难度增加。

Results: With the normal control group contrast, the HHD group has the varying degree cavity room to expand, with heart and soul expands 20 examples, the atrium sinistrum expands 49 examples, the left room expands 39 examples, the atrium dextrum expands 33 examples, the right room expands 24 examples, the pure atrium sinistrum expansion example number are most, reaches 11 examples, the room gap accumulation 24 examples, the left room behind accumulation 20 examples, the pulmonary artery inside diameter broadens 16 examples.

结果：与正常对照组对比，HHD组均有不同程度的腔室扩大，其中全心扩大20例，左房扩大49例，左室扩大39例，右房扩大33例，右室扩大24例，单纯左房扩大例数最多，达11例，室间隔增厚24例，左室后壁增厚20例，肺动脉内径增宽16例。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.
