细线期

In leptotene the chromosomes,already replicated, start to codense and appear as fine threads, althouge sister chromatids are not yet distinct.

在细线期，染色体已复制，开始浓缩，呈现出明显的丝状，尽管姐妹染色单体还未分开。

Modification of plasmodesmata occurred at leptotene stage, at which the cell wall was degraded by the release of the enzymes from the endoplasmic reticulum-derived vesicles after its fusing with the plasma membrane .

前者形成于细线期末，造成细胞壁降解的物质来自内质网分离到细胞质中的内质网小泡；后者形成于偶线期以后，造成细胞壁降解的物质来自于内质网与细胞质膜融合后内容物的释放。

This well prove that relative length of pachytene chromosomes was a stable data and it was more appropriate to act as a parameter to establish pattern on the condition of with same material.

用Image J染色体分析软件来测量家蚕粗线期染色体相对长度和绝对长度与传统的细铜丝测量相比，减少了步骤，降低了主观误差，大大提高了准确性和工作效率。2。

objective the purpose of this study was to summarize our experience of the application of internal rigid fixation with miniplate to treatment of mandibular fractures.methods a retrospective analyisis of clinical data of 67 cases,who had experienced the anatomic reduction and rigid fixation by using miniplate.with the help of maxillomandibular distraction pre operation and post operation and temporary maxillomandibular fixation during operation,the fracture bones were smoothly reduced and fixed.results clinical and radiographic examination showed that all cases gained good clinical results and precise anatomic alignment of fracture postoperatively without infection,malocclusion,bone malunion or other complications.conclusion mocortical miniplate fixation of the mandible is a reliable and effective techinique providing rigid fixation and an ideal modality for the treatment of mandibular fractures.combined with maxillomandibular fixation.

对67例下颌骨骨折患者的临床资料进行回顾总结，所有患者应用小型接骨板行坚固内固定治疗。其中7例颏部骨折，12例颏旁骨折，16例颏孔区骨折，9例体部多发性骨折，5例体部粉碎性骨折；18例合并其他部位骨折。所有患者术前经临床检查和影像学检查明确骨折的位置和骨折线的数目后，分段牙弓夹板结扎、颌间弹性牵引，使移位的骨折段逐渐复位；术中经口内切开复位、细钢丝颌间结扎、小型接骨板坚固内固定；术后行临床检查和影像学复查，必要时颌间弹性牵引7～10 d。结果所有患者手术切口ⅰ期愈合，治疗效果满意；临床检查所有患者牙合关系良好、面部对称；影像学复查证实骨折线对位良好。结论经口内切开小型接骨板坚固内固定辅以颌间固定治疗下颌骨骨折效果可靠，术后并发症少，是一种理想的手术方法。

Meanwhile the SHRIMP zircon U-Pb age of the fine-grained monzonitic granite is (131.4±1.6) Ma. These precise dating results represent the ore-forming period of this molybdenum deposit, the main dominant geological events and suggest its close relationship with buried Yanshan fine-grained monzonitic granite.

文章通过采集WZK1钻孔211.2~214 m细脉浸染状矿石的辉钼矿纯样，获得辉钼矿的等时线年龄为(134.1±3.3) Ma，并对比了矿区细粒二长花岗岩的锆石SHRIMP年龄(131.4±1.6) Ma，两者基本一致，表明矿床的形成主要与隐伏的燕山期细粒二长花岗岩有着密切关系。

Basal leaves 2-6, long petiolate; stipules over 1/2 adnate to petioles, broadly lanceolate, membranous, margin sparsely denticulate and ciliate or entire, apex acuminate; petioles 3-9 cm at anthesis, usually green, sometimes purplish, glabrous, nitid, elongated at fruiting to more than 20 cm; leaf blade glabrous on both surfaces or pubescent along veins, 3-sect, segments shortly stipitate, lateral segments deeply 2-fid, central segment deeply 2- or 3-fid, terminal lobes highly variable in shape and size, ovate-lanceolate, lanceolate, oblong, or linear-lanceolate, margin irregularly dentate or shallowly divided, sometimes triparted to pinnatiparted or 3-lobed, apex obtuse or acute.

基生叶2-6，具长叶柄；托叶超过1/2的贴生至叶柄，宽披针形，膜，边缘疏生细齿和具缘毛或全缘，先端渐尖；叶柄3-9厘米在花期，通常绿色，有时略带紫色，无毛，有光泽的，在果期拉长到超过20厘米；叶片两面无毛沿脉具短柔毛，3全裂，裂片具短柄，侧裂片2深裂，中裂片2或3深裂，顶裂片形状和大小极易变，卵状披针形，披针形，长圆形，或线状披针形，边缘不规则牙齿或浅裂，有时3深裂到羽状深裂或3浅裂，先端钝或锐尖。

The suspicion of cancer is increased by the following factors:(1) age (young patients are more susceptible);(2) sex, if the patient is a man (more women have thyroid cancer by a ratio of 2:1, but women have more thyroid disease by a ratio of about 8:1; thus, a man with a nodule should be regarded with greater suspicion);(3) a solitary nodule (multinodular lesions are usually benign unless there is a dominant cold nodule by thyroid scan);(4) a cold nodule on thyroid isotopic scanning (hot nodules are seldom cancerous);(5) a history of radiation exposure to the head, neck, or chest, especially in infancy and childhood (eg, for an enlarged thymus or enlarged tonsils, acne, or lymphoma);(6) radiographic evidence of fine, stippled psammomatous calcification or dense, homogeneous calcification;(7) recent or rapid enlargement; and (8) stony-hard consistency.

下列因素可增加癌的可疑性：(1)年龄；(2)性别，如果病人为男性(女性与男性的甲状腺癌比为2：1，但女性更多的是得甲状腺病，约为8：1，因此，男性有甲状腺结节时应考虑癌的可能性更大)；(3)孤立小结(多结节病变一般为良性，除非甲状腺扫描时呈明显的冷结节)；(4)甲状腺同位素扫描时发现冷结节；(5)有过头、颈、胸放射接触史，尤其是婴儿和儿童期(例如，因胸腺增大或扁桃体肿大、痤疮或淋巴瘤等)；(6)X线片见细、斑点状、沙粒样钙化或致密、匀质钙化；(7)最近增大或快速增大；(8)质地石头样坚硬。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
