Results: MR demonstrated capsule wall and papillary solid lesions in one case with cystic and solid lesions of hepatobiliary cystadenoma. Poly cystic form tan if different sine in sew case, capsule wall and septation was thick, part of capsule wall was obviously thickened and nodes form, intrahepatic bile duct was dilated, large poly-antrum cystic keen form structure in one case, capsule wall and septation were smooth, part of capsule wall was uniformly thicken, capsule wall, septation, mural nodus form and solid lesions in three cases wee all slightly hyperintense on T2WI and slightly hypointense on T1WI. Part of cyst fluid was hypointense on T2WI the diameter if tumor ranged from 3.4cm to 13.5cm. Part of capsule wall, septation, solid lesions and mural nodus west obviously enhanced in arterial phase in three cases, the extent of enhancement showed a little degrade in port vein phase, balance phase and delay phase, but dense to liver parenchyma at synchronization.

结果：3例肝内胆管囊腺瘤中1例呈囊实性结构，可见囊壁及乳头状实性肿块；1例为多个大小不等的多房囊状结构，囊壁及分隔光滑，囊壁局部明显增厚，有壁结节，周围见轻度的肝内胆管扩张；1例为巨大的多房囊状结构，囊壁及分隔光滑，局部均匀增厚；3例中的囊壁、分隔、壁结节及实性部分均呈T2WI稍高信号、T1WI稍低信号，囊内液性部分均呈T2WI高信号、T1WI低信号；肿瘤瘤体大小径线范围3.4~13.5cm.3例肝内胆管囊腺瘤中囊壁、分隔、实性肿块和壁结节动脉期均明显强化，门脉期、平衡期及延迟期强化程度略减低，强化程度均高于同期肝实质。

The transforming growth factor-β superfamily, a large group of highly conserved growth factors including TGF-βs, activins and BMPs, regulate a wide variety of cellular functions such as proliferation, differentiation, apoptosis and migration. Signals from these growth factors are transduced by a group of Smad proteins. To date, there are nine vertebrate Smads, including the receptor-activated Smads , Smadsl-3, 5 and 8, the common mediator Smad4 and Smad4β, and the inhibitory Smads, Smad6 and 7. Signaling is initiated when the ligand induces assembly of a heteromeric complex of type Ⅱ and type Ⅰ TGFβ receptors. Then R-Smads are directly phosphorylated by activated type I TGF-β receptors.

在多种SMADS中，SMAD5令我们产生兴趣，基于三个原因：1、Smad5基因敲除胚胎中发现卵黄囊的异位造血以及CFU-GM祖细胞数目增加，表明SMAD5可能是早期造血发育的负向调控基因。；2、应用反义核酸封闭Smad5可以逆转TGF-β对祖细胞增殖的抑制效应，表明它可能介导TGF-β信号转导，后者的异常，包括某些SMADS的功能异常，和白血病紧密相关；3、Smad5基因定位在人染色体5q21，此区域的缺失和急性髓系白血病和骨髓增生异常综合症相关，因此，Smad5被怀疑为白血病抑制基因。

Many species of red tide plankton and cysts of dinoflagellate provide the species sources for the frequent occurrence of red tide, and the suitable hydrometeorological conditions, specific living habits of some dinoflagllates and high N/P ratio may be the main causes for the occurrence of dinoflagellate red tide in the sea area, and the eutrophication has less relation to the frequent occurrence of red tide in the sea area in spring.

多种甲藻赤潮生物以及甲藻孢囊的存在为赤潮的频繁发生提供了种源，适宜的水文气象条件、某些甲藻独特的生活习性以及高N/P比有可能是导致该海域甲藻赤潮爆发的主要原因，富营养化与该海域春季赤潮频繁发生的关系较小。

Results:In this group there were 5 mucinous cystadenoma; 4 serous cystadenoma; 4 teratoma; 2 lager ovarian cyst; 4 subserous leiomyoma of uterine. The massive cystic-solid tumor with irregular cystic wall was seen in mucinous cystadenoma and serous cystadenoma; Teratoma appeared non homogenous density with fat density mass; Subserous leiomyoma of uterine showed large cystic tumor with clear edge, and the size of uterine was normal.

结果：5例卵巢浆液性囊腺瘤，4例黏液性囊腺瘤，CT表现为腹盆腔内巨大囊性或囊实性肿瘤，囊壁厚薄不均；4例卵巢畸胎瘤，CT表现为盆腔巨大肿瘤内部密度不均，可见脂肪密度影；卵巢巨大囊肿2例，CT表现为腹、盆内巨大单囊状肿物；4例浆膜下子宫肌瘤，CT表现为盆腔内巨大囊性肿物，边界清晰，子宫大小正常；1例阔韧带平滑肌瘤，CT表现为密度不均匀的实性肿物，增强扫描强化不均。

SEM analysis indicated that the dispersive state of nature rubber latex was improved with the addition of organosilicone. The two batch formulas were adopted in the manufacture of urethral catheter with an optimal addition of 1.5% of KGF-903. The catheters were obtained with smooth surface, finer evenness, moderate hardness and favorable yield of latex sacculus. The separation forces between connector and the interface of conical drainage as well as the tensile force between gas loading filler and drainage tube were improved, which guaranteed the safety of Foley latex in clinic use.
