Results Microscopically, different degrees of hepatocytic degenerative changes and hyperplasic fibrous tissue and typical false lobule formation could be seen. Timm's staining result showed uneven distributed black granular deposits in the hepatocytes. No specific PAS staining was observed. Utrastructurally, the mitochondria were increased in volume and dramatically different in shape. The number of lysomes were increased.

结果 光镜下肝细胞表现为不同程度的退行性变，胶原纤维增生以及典型假小叶形成；Timm's染色阳性，发现不均匀分布黑色颗粒或团块样物质沉积；PAS染色则普遍缺乏特异性染色；超微结构显示线粒体形态多样，体积增大，溶酶体增多，粗面内质网管腔扩张，附着核糖体的脱颗粒，以及胞质水肿，质膜溶解。

At the one-cell stage, each embryo was injected with gradient doses of 2-8ng MO. The control morpholino, was purchased from Gene-Tools.To test the knockdown effectiveness of the morpholino, the tbx2-EGFP (enhanced green fluorescent protein) construct was generated. And coinjection of morpholino with mRNA tests its specificity of the morpholino. Overexpression of tbx2 via mRNA microinjection helps us understand gaining function of tbx2. Results The tbx2-EGFP construct tests the knockdown effectiveness of the morpholino. Zebrafish embryos lacking tbx2 function have defects in cardiac contractility, rhythm and morphology in a dose-dependent manner. The embryos with c-MO are normal in development. Coinjection of morpholino with mRNA rescue the phenotype of tbx2 knocking down. The phenotypes include pericardial edema, hypogenetic ventricle, dilation of atria, arrhythmia, bradycardia, asystole, abnormal atrioventricular canal, aberrant valve and blood regurgitation.

结果荧光蛋白融合标记实验验证了tbx2-MO可以很好得阻抑斑马鱼胚胎tbx2的表达，tbx2-MO组胚胎在心脏收缩性、节律和形态学发生上出现了异常，心脏畸形随着注射剂量的增加而出现比较一致的表型，而c-MO组胚胎没有出现明显的畸形；tbx2-mRNA和tbx2-MO的共注射减少了tbx2-MO胚胎心脏畸形的发生率及减轻了心脏畸形的程度，验证了所设计合成的tbx2-MO对tbx2基因的抑制作用具有特异性；tbx2-MO组胚胎心脏缺陷包括心室发育不良、心房扩张、房室管和瓣膜异常以及心率缓慢、心律不齐、心脏停搏、血液返流等，并根据心脏发育异常的程度分为轻、中、重度畸形组tbx2-mRNA基因过表达胚胎没有见到心腔的形成。

Fibrin exudation, pulmonary interstitial incrassation, thrombosis of pulmonary artery, hemorrhage and gore were found. Conclusion: MR enhanced pulmonary perfusion can diagnose pulmonary embolism.

病理显示：梗死区可见大量的纤维素渗出，肺间质增厚，动脉腔内可见红细胞和血栓形成，其周围白细胞浸润伴肺淤血，部分可见点状出血及肺淤血。

The use of rhBMP2 for interbody fusion is associated with high fusion rates.

但是，对于后路手术，却有着在硬膜外腔隙内异位骨形成的担忧。

The intracystic hydrostatic pressure was significantly higher than that in normal nephrons in 95.6% of the cysts, and was definitely related to the volume of the cysts.

这些梗阻因素使管内尿流阻力增大，压力升高，管腔局部扩张，最终囊肿形成。肾单位梗阻在成人多囊肾发病中起重要作用。

Twelve hours latter,uterine vessels formation was revealed by tannin-Fe lavement solution.Results The uterine vessel formation of rats in the model group showed that varices,tetanic shape,the density of all levels vessel net increased obviously and its twist,serpentine shape decreased markedly,while that in the large,middle dosage Gongning groups displayed absolute contrarily and fit like a glove with the normal control group.The uterine vessel formation of rats in the small dosage Gongning group and indomethacin group also showed the same transformation as it in the model group.

结果 模型组大鼠子宫各级血管扩张增粗，走行僵直，螺旋状和蜿蜒状走行消失或明显减少，血管形成的各级血管网密度增加，分布不均；消炎痛组、宫宁小剂量组子宫血管仍存在较明显的血管腔扩大、走行僵直和血管网密度增加，宫宁大、中剂量组子宫血管构筑的异常改变消失或明显改善。

As this infarct in the brain is organizing and being resolved, the liquefactive necrosis leads to resolution with cystic spaces.

脑组织梗死灶正在进行机化并且逐渐被溶解液体吸收后往往形成囊腔。

The major manifestations of MR imaging included synovial hyperplasia and pannus formation, joint effusion, bone marrow oedma, adnormality of signal and shape of meniscus, soft tissue swelling, cartilage destruction,popliteal lymphagogue, et al.

结果42例JIA患者的42个膝关节可见不同程度的MR异常改变（100%），主要影像学表现包括滑膜增生及血管翳形成、关节腔渗出积液、骨髓水肿、半月板形态及信号异常改变、关节软骨破坏、腘窝淋巴结肿大等。

Staining observation on complex mesochondrium of marrow-derived mesenchymal stem cells-TCP: It was found with TB staining that the complex of marrow-derived mesenchymal stem cells-TCP inside the joint cavity obviously had positive staining, which indicated that there were glycosidoprotein base formed.

骨髓基质干细胞-磷酸三钙复合体软骨基质特染观察结果：甲苯胺蓝染色发现，植入关节腔的骨髓基质干细胞-磷酸三钙复合体有明显阳性染色，表明有糖蛋白基质形成。

These results revealed that the pollen chamber developmental pattern passed through four phases. Firstly, a group of nucellar cells at the micropylar end elongated longitudinally. Thereafter, the uppermost nucellar cells at the micropylar end initiated PCD; and these elongated cells undergoed PCD in a basally and laterally oriented direction to form a cavity.

贮粉室的形态发生可分为4个阶段：最先是位于珠孔端的几层珠心细胞纵向地伸长；接着，珠孔端最顶部的珠心细胞发生PCD；然后，那些已经纵向伸长的珠心细胞向基地和侧向地依次发生死亡，产生贮粉室空腔；最后，珠孔端的珠心表皮细胞发生开裂，形成贮粉室的开口。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
