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。

Methods: On single-plane and biplane DSA images (including cases with normal ventricular wall motion,hypokinesia and insufficient mixing of contrast medium in ventricular cavity) the area-length method and videodensitometry method were used to calculate the volume and EF respectively.

结果：双向造影的长度-面积法EF测量值与实际值无显著性差异(P＞0.05)；单向造影的测量值在局部室壁运动减弱时差异显著(P＜0.01)；视频密度测量法在室腔内造影剂混合不均时测量值有显著差异(P＜0.01)。

Hyponome in rectum helps to show the institutional framework around the focus and improve the image to study contrast ratio.

应用直肠腔内水囊结合相控阵线圈的MRI检查方法，能准确定位复杂性肛瘘的内口、瘘管的走向及其与肛管直肠括约肌复合体之间的复杂关系，有利于显示病灶周围组织结构和提高影像学对比度。

Hormone level in maturation medium affected cumulus expansion of COC, but cumulus expansion became less dependent on hormone level with time of culture. Porcine immatured oocytes, granulosa cells from small antral follicles and cumulus cells of immatured oocytes secreted cumulus-expansion enabling factors. Granulosa cells from 3-6mm follicles did not produce CEEF, but there was some CEEF in the follicular fluid of this sized follicles.

激素水平对卵丘扩展有影响，但随培养时间的延长，对激素的要求有逐步减少的趋势；猪卵丘扩展不依赖于卵母细胞，卵母细胞核成熟也与卵丘扩展无关；GV期卵母细胞、小腔卵泡内颗粒细胞和成熟卵的卵丘细胞都有较高的分泌CEEF能力；3-6mm卵泡的壁颗粒细胞不能分泌CEEF，但3—6mm卵泡的卵泡液中有CEEF。

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。

On MR images, fluid-fluid levels were seen in 12 cases (92%); the internal septations and walls of the cysts were inhomogeneously enhanced markedly, these septations and walls were not evident on T1WI, but with medium to high signal on T2WI.

CT显示21例（91%）病变由大小和数量不等的囊腔构成，其中19例（90%）CT扫描出现液-液平面；4例（17%）病变内出现局部实性区域，其中1例为完全实性病变；3例病变侵犯了邻近关节和骨。

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 characteristic of the treatment by manipulation with acupotomy in tensive position is manipulating the adhesions and contractures of capsule in direction: including the zona of intertubercular sulcus, inferior-acromial and the decocted later part of the capsule, and with hydraulic distension and manipulation. Compared with manipulation maneuver this treatment is less traumatic, short of course of treatment, easy to perform and really an effective procedure to treat the frozen shoulder.

粘连挛缩带紧张位针刀松解治疗方法特点在于针对性地松解肩前结节间沟区、肩峰下和肩关节囊后下部等三处粘连挛缩带，在此基础上配合关节腔内注液扩张和术中术后注重肩肱关系的手法松解，与推拿治疗冻结肩相比，本法明显改善了冻结肩患者的疼痛与功能障碍程度，创伤小，疗程短，见效快，疗效可靠，且中远期随访显示疗效稳定。
