Results There was not specificity of clinical symptoms in liposarcoma of the orbit, the major clinical aspects were intraorbital occupied lesion and local hyperaemia,swell and pain which was similar to an acute inflammation. Four different subtypes of liposarcomas could be observed in orbit.In past literature,myxoid was the most common subtype（14 cases,70%）,secondly subtype was well differentiated（3 case）,round cell and pleomorphic subtype were rare（each 1 case）.This case was well differentiated mixed component of round and pleomorphic lipoblasts.

结果：脂肪肉瘤临床表现为眶内占位和貌似急性炎症的局部红、肿、痛，无特征性的症状；病理分型4型，文献中报道以粘液样型最多见（14例，占70%）；次为分化良好型，3例；圆形细胞为主型及多型性各1例；分型不详2例；本例为分化良好型为主伴有圆形脂母细胞及多型性脂母细胞成分。

Dedifferentiated liposarcoma, occurring in up to 10% of well differentiated liposarcoma cases, has similar histologic features to that of undifferentiated high-grade pleomorphic sarcoma; the former develops in a background of atypical lipomatous tumors/well differentiated liposarcoma, whereas the latter shows no specific line of differentiation.

去分化脂肪肉瘤占高分化脂肪肉瘤比例达10%，其形态特征与未分化高级别多形性肉瘤有相似之处；前者发生在不典型脂肪肿瘤/高分化脂肪肉瘤的背景上，后者无特定分化方向。

In gastric carcinoma, the 5CpG island methylation of p1 6 gene promoter occurred in 33.33%(2/6 cases) of well and mediately differentiated carcinomas and 57.89%(11/19 cases) of poorly differentiated carcinomas.

胃癌组织p16基因启动子5'CPG岛甲基化显著高于正常组织，说明该基因上游调控序列的甲基化可能是胃癌形成过程中的一个重要分子标志。

When Fas and c-myc protein were coexpressed in cytoplasm, a strong positive sign appeared in highly differentiated osteosarcoma, fibrous dysplasia of bone and osteoplast of bone callus, a weak sign was found in low-differentiated tumour cells and fibroblasts.

Fas和c-myc蛋白胞浆内阳性，在骨肉瘤的高分化细胞(骨母细胞型和软骨细胞型瘤细胞)和骨化性纤维瘤、骨纤维结构不良、骨痂组织中骨母细胞呈强表达；而在低分化瘤细胞和纤维母细胞则呈弱表达。

Results In 9 cases of endometrial biopsy of materials by uterine curettage, the cells of endometrial stromal sarcomas of 6 cases were well differentiated and like stromal cells of endometrial hyperplasia; the cells of endometrial stromal sarcomas of 3 cases were poor differentiated, the cells of 2 were like that of malignant lymphoma, and another like that of pleomorphous sarcoma. In 9 cases were found the distribution of vessels cluster like endometrial corkscrew small artery. The tumor cells were grew along lymphatic or protruded in lymphatic, and there were small islands or small pieces of tumor cells in the interspace of muscles in 2 cases. The contrastive observation of the specimens of resected uterines of 9 cases confirmed the valve of above features to the confessed diagnosis of endometrial stromal sarcomas in the materials of endometrial biopsy or uterine curettage.

有3例分化差者，其中2例酷似恶性淋巴瘤，1例酷似多形性肉瘤。9例均见簇状分布的子宫内膜螺旋小动脉样的小血管分布，2例见瘤组织沿淋巴管和突入淋巴管内生长及小片平滑肌组织的肌间隙内有小灶状或小片状瘤组织分布。9例子宫切除标本的对比观察，进一步证实了上述特征对宫内膜活检或刮出物确诊子宫内膜间质肉瘤的价值。

In order to differentiate real-time traffic from best-effort traffic in multi-hop Ad hoc networks, a new differentiated medium access control scheme, differentiated label-swiching distributed coordination function is proposed. Forwarding information is obtained by label in MAC layer and is piggybacked in Request-acknowledgement frame.

为了在多跳Ad hoc网络中提供实时业务和尽力而为业务的区分服务，提出了一种支持区分服务的媒体接入控制机制――支持区分服务的标签交换分布式协调功能。

We found that after transplanted 4 weeks, partially differentiated ESCs (already developed into the stage of neural progenitor cell) could survive and that some of them differentiated into TH-positive cells which had Nissl's body in plasm.

结果显示：诱导后的ESC植入纹状体后可以存活并有部分细胞分化为TH免疫阳性细胞，胞质中有尼氏小体的出现，说明ESC已分化为多巴胺能神经元。

It is further confirmed by the experiment of muti-inducement that MSMPs can differentiate into osteocyte sand fibrocartilage cytes and it is osteo-chondro progenitor cells with the potential ability to evolve muti-differentiated. This added evidence to the view that condylar cartilage differentiated from osteo-chondro progenitor cells in the mesenchymal cells of mancibular periosteal.

体外分离培养鼠胚下颌体骨膜间质细胞并研究其生物学特性，通过多向诱导实验进一步证实：下颌骨膜间质细胞可能为骨—软骨的前体细胞，可分化为成骨细胞及纤维软骨细胞，具有多向分化潜能，此结果进一步支持髁突软骨是由下颌骨膜间质中骨—软骨前体细胞发育而来。

Results:The positive expression of P53 and c－Myc protein in nuclei was bound up with poor-differentiated tumours;the positive expression of Fas and c－Myc protein in cytoplasms was consistent with well-differentiated tumours.

采用免疫组织化学方法对骨肉瘤、骨化性纤维瘤、骨纤维结构不良和正常骨痂组织进行c－Myc、Fas和P53蛋白测定，与肿瘤组织学分级、细胞分化及核丝分裂比较分析。

EA which is rare, malignant and high in incidence of metastasis belongs to a relative histopathologically well-differentiated sub-group of eccrine carcinoma.1 It usually presents as a nodular lesion on the head and neck region and is difficult to be differentiated from a visceral neoplasm with cutaneous metastasis.

小汗腺癌是罕见的恶性肿瘤，并有很大可能出现转移，属于组织学方面相对分化良好的汗腺癌的亚细分组。它通常表现为在头颈部区域的的小结节，在显像研究时很难与内脏恶性肿瘤的皮肤转移癌相区分。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
