EGFL7 protein is a factor specially secreted by the endothelial cell. It is necessary for formation of vascular lumen, the formation process would be blocked and functions of vascular is incompleted if it is missing.

论文摘要： EGFL7蛋白为一种内皮细胞特异性分泌因子，它是血管管腔形成所必需的因子，它的缺乏将导致管腔形成受阻，从而影响血管功能的完善。

The existence of indissolvable interlayers leads to many adverse effects for building salt cavern storages by solution mining. It is an urgent technical problem that how to forecast and control the collapse of indissolvable interlayers.

Results CT scans showed the density of the involved sinus cavities rised inhomogeneously in all patients, spot or lump calcification in 17 cases, the medial wall of maxillary sinus were and absorbed and destroyed in 5 cases, ostium of maxillary sinus was expanded in 11 cases...

结果CT征象：病变的窦腔内为不均匀的密度增高影，其中17例病变窦腔内呈不规则点状或片状钙化影，5例上颌窦内壁骨质吸收破坏，上颌窦口扩大11例，上颌窦骨壁增生硬化16例。

Results: The normal epithelial cells were intactly lined with microvilli, and lesions on the surface of Ct infected cells were showed by SEM. The expression of actin was obvious throughout the cytoplasm of uterine epithelial cells but appeared to be most intense along the apical plasma membrane on day 4, 5 and 6 of pregnancy. On the day 7, levels of actin had increased along the apical surface. The expression of actin in the infected group was weaker than that in of the normal group.

结果：SEM示对照组子宫腔可见有微绒毛的分泌细胞；实验组腔上皮细胞表面有的可见破损，微绒毛少见；免疫组化结果显示荧光强度主要定位于腔上皮细胞胞质／胞膜，妊娠第4，5，6天沿胞质顶部分布较密集，而底部较弥散；妊娠第7天顶部强度有所增加；感染组的荧光强度均弱于相应正常组，在妊娠第5天存在显著性差异(p.05)。

Patients with intrabronchial benign tumor showed nodules in trachea and bronchial lumen on CTVB, and without wall thickening on transverse CT.

另1例支气管腔内异物CTVB表现为支气管腔内隆起性阻塞，横断面CT无相邻支气管壁的增厚。

Methods:The treatment of 18 cases with bone cysts was reviewed,which there were treated from January 2004 to February 2005. There were12 males and 6 females with an average age of 13 years?old. The bone cysts were located in the proximal humerus（n=9）,proximal femur（n=4）,proximal tibia（n=1）,distal tibia（n=1）,proximal ulna（n=1）,distal ulna（n=1）,and distal radius（n=1）.Under fluoroscopy, two fine bone marrow biopsy needls pierced the bone cysts from the top and the bottom of the cyst respectively.The intracystic fluid was drawn out,the cyst cavity was irrigated and then the tissue engineering complexation of autologous red bone marrow and methylprednisolone with sodium hyaluronate was injected in percutaneously.

2004.1～2005.2月，对18例骨囊肿患者（男12例，女6例，平均年龄13岁；其中肱骨近端9例，股骨近端4例，胫骨近端1例、远端1例，尺骨近端1、远端1例，桡骨远端1例）以玻璃酸钠为载体抽取自体红骨髓加入甲基强的松龙，在X线透视下，将2根骨穿针经皮分别自囊腔顶部和底部刺入骨囊肿内，抽去囊液，冲洗囊腔后注入复合物。

BACKGROUND: Implantation of artificial joint of bone cement can result in long-term blocking of recipient site medullary canal and blood vessel lesion, and lead to changes in intraosseous pressure and bone blood flow of distal femoral shaft.

背景：骨水泥固定型人工关节假体骨腔内的植入必然涉及受区骨髓腔的长期闭塞和髓内血管的破坏，由此而产生的髓内压和血流的变化是材料本身的影响所致，很有研究价值。

Group B received the treatment of removing fluids from the pericardial cavity with pericardiocentesis intermittently and intrapericardial injection.

将76例结核性渗出性心包炎患者随机分为A组和B组，均予以全身规则抗结核治疗。A组留置中心静脉导管引流及心包腔内注药，B组常规心包穿刺抽液及心包腔内注药。

After salpingitis tubal atresia adhesion, mucosal cells in the secretion of fluid accumulation within the lumen, or isthmic tubal inflammation and adhesions umbrella side, blocking the formation of fallopian tube, when the lumen is absorbed within the suppurative cells , after eventually become liquid water.

在输卵管炎后，因输卵管粘连闭锁，粘膜细胞的分泌液积存于管腔内；或因输卵管炎症发生峡部及伞端粘连，阻塞后形成输卵管积脓，当管腔内的脓细胞被吸收后，最终成为水样液体。

In this paper, characteristics of generating hydrogen from methane wet air catalytic reforming reaction on the premixed chamber wall with Ni katalyst was done with numerical simulation, using both CFD FLUENT and surface chemistry subroutine CHEMKIN for the microscale combustor premixed chamber the author proposed.
