三类麻纤维中，由于苎麻纤维纵向的不均匀性及相对较小的比表面积，使苎麻纤维构成的织物透气性最好。

"We've been able to take very large fibroids (12-14 cm in diameter) out through these small incisions by first morsellating the fibroid with a scalpel before enucleating it," said Dr. Glasser, noting the advantage over laparoscopy, which is not recommended for fibroids greater than 7 cm in diameter."It's a little different approach, but it works very well and it's a hemostatic way of performing a myomectomy," he added.

Glasser医师表示，在清除步骤前，会先以解剖刀捣碎纤维瘤，如此一来，我们可以经由这些小切口来去除很大的纤维瘤(12到14公分的直径)；相较於腹腔镜手术法，这个方法具有较高的效益，因为腹腔镜手术法并不建议用在去除直径大於7公分的纤维瘤；这个方法有一点不同，但是效果很好，而且在进行肌瘤切除时，此法具有很好的止血性。

Scanning electron microscopy,transmission electron microscopy,circular dichroism and small-angle X-ray diffraction were used to analyze the aggregation mode of CSG in the organogel phase.A hierarchical self-assembly model was proposed to explain the transition from molecular to primary and secondary structure.It is shown from our results that CSG can aggregate into a micellar fibril nanostructure with high length-to-width ratio which is bundled and entangled to form a three-dimensional(3D) network that immobilize the fluid component probably by surface tension.Moreover,sol-gel polymerization of tetraethoxysilane was carried out using CSG in the gel phase.

Results The anterior bundle of ulnar collateral ligament originates from the inferior aspect of the medial epicondyle and inserts immediately adjacent to the joint surface on the ulna near the sublimis tubercle. The posterior bundle originates from the medial epicondyle slightly posterior to its most inferior portion and inserts broadly on the olecranon process. The lateral collateral ligament arises from the inferior aspect of the lateral epicondyle. Two types of conjoined lateral collateral and annular ligamentous insertions on the ulna were observed. Type Ⅰ(61.2％) was bilobate and type Ⅱ(38.8％) was a single broad conjoined type with insertion on the ulna. The anterior band of anterior bundle was more tighten than the posterior band as the elbow flexed less than 60°. When the elbow flexed over 60°, the two parts of anterior bundle were equally tightened. The posterior bundle was tightened as the elbow was flexed more than 90°. The lateral collateral ligament was tightened gradually as the elbow moved in flexion.

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

Except cellulose acetate fiber,the strength of other four-kind fibers in completely dry state is decreased notably after MHT.With the initial moisture regain increased,the breaking elongations of cotton,rayon and loycell are improved remarkably after MHT.The increasing level is rayon＞loycell＞cotton,but ramie seems little improved.As the moisture regain is low,the fiber initial modulus is enhanced.However,when the moisture regain is higher,the fiber initial modulus did not change obviously.
