叶状

The tumor is lobulated under microscope, some immature Sertoli cells were arranged as either amorphous plaques, funicular, broad beam, nest, solid or hollow tubules; Leydig cells existed individually or in clusters, and their cytoplasm was abundant and eosinophilic.

镜下肿瘤呈分叶状，有不成熟的支持细胞排列呈片块状、不规则形或条索状、宽梁状、巢状、实性或空心的小管；莱迪细胞呈单个或簇集存在，细胞浆丰富且嗜酸。

Results: Most synovial sarcomas located in the extremities close to joints. Synovial sarcomas detected by radiography typically appeared as round, oval or multilobulated juxtaarticular soft-tissue masses with calcification in some cases. The most common CT appearance of synovial sarcoma was heterogeneous deep -seated soft-tissue mass with attenuation similar to or slightly lower than that of muscle. On T1WI, synovial sarcomas typically appeared as prominently heterogeneous multilobulated soft tissue masses with signal intensity similar to or slightly higher than that of muscle. On T2WI, synovial sarcomas appeared as prominent heterogeneity with predominantly high signal intensity.

结果：大部分滑膜肉瘤位于关节旁；X线表现为圆形、椭圆形或分叶状软组织肿块，部分可见肿块内钙化；典型的CT表现为较深在的、等或稍低密度不均匀的软组织肿块；磁共振T1WI与肌肉信号相比，滑膜肉瘤表现为分叶状、不均匀、等或稍高信号，T2WI则表现为高信号为主的不均匀信号；DSA呈显著的肿瘤实体染色及新生血管。

Type genus of Sphaerocarpaceae; liverworts with small many-lobed usually orbicular thallus.

球蒴苔科的模式属；地钱，具有小的多数情况下呈叶状环形叶状体。

Results: The main manifestations of imaging in PCCCL appeared as peripheral nodules or masses (6/7) in the right lung. Tiny nodules with coarse spiculate margin, lack of pleural indentation and vacuole sign. When masses of turmor grew larger, smooth margins were found in them. spinous process and cavity were seldom seen. Central mass of left lung superior lobe (n=1), lesion was lobulated, and with smooth margin, which seem others central carcinoma of the lung.

结果：PCCCL影像学上主要表现为右肺周围性肿块或结节(6/7)，结节边缘可见毛刺征，无胸膜凹陷征、空泡征；肿块较大时，边缘光滑，无棘状突起、空洞等征象，1例左肺上叶中心性分叶状肿块，边缘光滑，酷似其它类型肺癌。

Shrubs, erect, rarely treelike, deciduous; new leafy shoots from axils of leaves of past season; young shoots sometimes verticillate, not scaly, setose, pubescent or glabrous.

灌木，直立，很少乔木状，落叶；新叶状枝生自以前季节的叶的腋的；有时轮生的幼枝，无鳞片，具刚毛，被短柔毛或无毛。

Flowers unisexual and plants dioecious; inflorescences without leaflike bracts or with few caducous leaflike bractlets; seeds abaxially longitudinally furrowed for 3/5 length

单性的花和植株雌雄异株；花序没有叶状苞片或具很少早落的叶状的小苞片； 3/5的期间的种子背面的纵沟 11

These two kind of diseases have their own characteristics in clinical and imaginal representation.but misdiagnosis is still happened.We misdiagnosis one huge breast mase of 28 years old female in April,2002,whose diease come on during pregnancy and lactation.

乳腺纤维腺瘤与乳腺叶状囊肉瘤在临床和影像学表现方面都有其特征性，但临床上仍常出现误诊的情况，我们于2002年4月收治1例发病于妊娠哺乳期的28岁右乳巨大肿块女性病人，术前根据临床表现及影像学检查的结果考虑右乳叶状囊肉瘤的诊断，而术后的病理报告为乳腺纤维腺瘤。

Results All patients accepted operation treatment,postoperation 5-year survival rate is 100%,recurrence rate of phyllodes tumors is 14.28%,recurrence rate of breast adenoma fibrosum is 2.50%,misdiagnosis rate of phyllodes tumors is 37.5%.

结果 所有患者均经手术治疗，术后5年生存率100%，乳腺叶状肿瘤术后复发率14.28%，纤维腺瘤术后复发率2.50%，分叶状肿瘤的误诊率37.5%。

From August 21, 1998, to December 14, 2001, 57 core needle biopsy specimens suggested the possibility of phyllodes tumor. Median patient age was 42 years (range, 16-77 years), and median lesion diameter was 1.1 cm (range, 0.6-3.6 cm). Of the 57 specimens, 25 had pathological findings favoring a diagnosis of fibroadenoma, 23 favored phyllodes tumor, and nine were equivocal.

从1998年8月21日至2001年12月14日，共有57个粗针切片检查样本显示出叶状瘤的可能性，这些患者年龄中位数为42岁（范围16-77 岁），病灶直径中位数为1.1 厘米（范围 0.6-3.6 厘米），在57 个样本中，25个的病理研究结果建议为纤维性瘤，23个为叶状瘤，其余的九个诊断的意义不明确。

For the 23 core biopsies suggesting phyllodes tumor, excisional biopsy confirmed the diagnosis in 19 but revealed fibroadenoma in four patients, for a positive predictive value of 83%. Final pathological analysis of the equivocal core biopsies diagnosed fibroadenoma in five patients and phyllodes tumor in four patients. Final analysis determined that none of the lesions were malignant.

23个核心组织切片检查建议为叶状瘤的患者，进行切除的组织切片检查后，确认了19名患者的检验结果，但是有4人为纤维性瘤，因此得到83%的阳性预测值，有歧异的粗针检查进行最后的病理分析后，发现五名患者为纤维性瘤，而四名患者为叶状瘤，最后的分析测定这些肿瘤都不是恶性的。

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。
