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。

Oral Kaposi's sarcoma Kaposi's sarcoma, whether oral or extraoral in the mouth can be made one or more painless, purplish red or purple, of varying size, shape, flat or raised lesions, or plaques were porphyritic sheet that includes a capillary plexus, soft, similar to hemangioma, with moderate pain.

口腔卡波西肉瘤口腔卡波西肉瘤无论在口内或口外均可单发或多发无痛的、紫红或紫色的、大小形状不一的、扁平或隆起的病损，呈斑状或斑片状，其中含毛细血管丛，质软，类似血管瘤，有中度疼痛。

20 Centuries 60 time, american Gristina put forward, all biology material are embedded inside body hind, its surface all can form a kind of biomembrane, bacterial criterion is many in this kind of biomembrane progenitive, the many mucilage outside producing a cell is qualitative (Extracellular Slime Substance, ESS), it is the easy hair sex that causes false body infection and the main factor that study a gender hard.

概要： 20世纪60年代，美国Gristina等提出，所有的生物材料植入体内后，其表面均能形成一种生物膜，细菌则在这种生物膜中大量繁殖，并产生细胞外多粘质物质(Extracellular Slime Substance，ESS)，是导致假体感染的易发性和难治性的重要因素。

The tryptophan auxotrophs and the kanamycin resistant prototrophic revertants have been proved to contain a copy of Tn5 inserted in the chromosome by Southern Blot analysis with DIG-labeled 3. 5 kb HindⅢ fragment of pkan2 as the Tn5 probe. Four typies of prototrophic revertants could be found by the above assay.

用Tn5探针进行的Southern分子杂交证明Tn5在色氨酸营养缺陷型菌株及部分Km抗性原养回复突变型菌株中均插入在染色体DNA上，并且对菌株本身具有的内源性质粒的数目及大小没有带来影响。

Signalling through CXCR4 mediates actin polymerization and pseudopodia formation in cells, and induces chemotactic and migration to target organs. In addition, CXCR4-SDF-1 axis can promote tumor angiogenesis and growth.

CXCR4在肿瘤组织中的表达明显高于正常组织，而肿瘤常见转移部位均为CXCR4的配体基质细胞衍生因子-1(stromal cell derived factor-1，SDF-1)表达丰富的器官，SDF-1与CXCR4结合后可使细胞肌动蛋白丝聚合，形成伪足，从而定向诱导肿瘤细胞迁移到特定的靶器官；此外，CXCR4与其配体SDF-1相互作用可以促进局部新生血管作用，利于肿瘤生长。

The germination test of Sporocarps of Microlepia hancei prantl had been done, the callus can be induced from the delicate stem of Microlepia hancei prantl; The inducement and proliferation medium of callus was MS＋6-BA2 mg/L+NAA0.2 mg/L;the optimal combination of hormones of buds differentiation was MS+6-BA 0.4 mg/L; the effect of MS medium in radication culture was better than 1/2MS, the roots of plants were all efficiently induced in MS medium without reference to adding IBA、NAA or IBA＋NAA, the rate of radication was high; the effect of seedling cultured in the mixture of perlite and turf soil was better than perlite、garden soil and river sands.the mixture of perlite and turf soil has the excellences such as ventilate、water conservation 、nourishment and so on,the survival rate was higher and seedling substance was also hale.

试验进行了华南鳞盖蕨孢子果的萌发试验，并利用幼嫩茎段进行诱导愈伤组织；愈伤组织的诱导与增殖培养基为MS＋6-BA2 mg/L+NAA0.2 mg/L；其芽分化最佳激素组合为MS+6-BA 0.4 mg/L；生根培养中MS基本培养基比1/2MS效果好，MS基本培养基不论附加生长素IBA、NAA或IBA＋NAA，均能有效地诱导植株生根，生根率高；假植以珍珠岩和泥炭土的混合物为基质效果优于珍珠岩、菜园土和河沙，具有通气、保水、营养等优点，假植成活率高，苗势健壮。

Meanwhile, root to shoot ratio of the ramet grown in low light intensity and high nutrient availability significantly increased while that of the ramet grown in high light intensity and low nutrient availability greatly decreased.

深度遮光、低养和高盐均显著削弱金戴戴的生长，其生物量、叶面积、分株数、匍匐茎长及叶柄长和根冠比对基质盐分的可塑性大小和格局显示出基株间的差异。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
