Results There were 14 cases of tubal pregnancy (9 were located in ampullae ,4 were in interstitial trpes and 1 was in interstitial);And one cases were ovarian pregnancy.whose signs of CT were cystoid bump in the pelvic cavity,with uneven density and unclear interface with organization of surroundings, Cystoid wall or blood vessel of the part were intensified and there was no change inside the cystoid,concomitancy with hyperaemia of pelvic cavity.

结果 14例异位妊娠发生在输卵管(9例位于壶腹部，4例位于伞端，1例位于间质部)，1例发生在卵巢；CT表现盆腔囊实性肿块，密度高低不均，与周围组织分界不清，增强后囊壁强化或局部血管样强化而内部无强化，合并盆腔积血。

This appearance is due to the obstruction to the efferent loop at the neck, resulting in dilatation of the loop within the hernial sac.

Megaspore development and abortion of"Pingyi Tiancha"Compar-ing with regular developing megaspore of normal M.baccata,the megasporemother cellof"Pingyi Tiancha"could form mono-nucleus embryo sacby perhaps irregular meiosis,then most of sexual MES depauperatedand degenerated,finally aborted,or only a few further developed.Of asexualembryo sac,one or more large cells at the chalazal end of nucellus developed in-to one to more asexual embryo sac initials.After the competition between sexu-al embryo sacand asexual embryosac,most ovules only had one asexual embryo sac matured.

平邑甜茶大孢子的发育和败育与正常发育的山定子大孢子对比，平邑甜茶大孢子母细胞经减数分裂能形成单核胚囊，之后多数有性胚囊萎缩、退化而败育，只有极少数进一步发育；而无性胚囊则从胚珠合点端1个或多个较大的珠心细脆形成并首先发育为一个或多个无性胚囊原始体；经过有性胚囊和无性胚囊以及无性胚囊和无性胚囊之间的竞争，多数胚珠只有一个无性胚囊成熟。

Dissect the fascia from the dorsum down to the bursa oer the medial aspect of the metatarsal head. Then make a cured incision through the bursa and capsule of the joint Fig. 1-24,; begin the incision oer the dorsomedial aspect of the joint, continue it proximally dorsal to the metatarsal head and then plantarward and distalward around the joint, and end it distally on the medioplantar aspect of the metatarsophalangeal joint.

然后弧形切开滑囊及跖趾关节囊图1-24，，切口起自关节背内侧，自跖骨头背侧向近端延长，然后转向跖侧，再转向远瑞，环绕关节而行，最后在远端终止于跖趾关节的跖内侧面，此切口形成一椭圆形网球拍状组织瓣，连接于近节趾骨的基底部

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。

Dissect the fascia from the dorsum down to the bursa over the medial aspect of the metatarsal head. Then make a curved incision through the bursa and capsule of the joint Fig. 1-24,; begin the incision over the dorsomedial aspect of the joint, continue it proximally dorsal to the metatarsal head and then plantarward and distalward around the joint, and end it distally on the medioplantar aspect of the metatarsophalangeal joint.

然后弧形切开滑囊及跖趾关节囊图1-24，，切口起自关节背内侧，自跖骨头背侧向近端延长，然后转向跖侧，再转向远瑞，环绕关节而行，最后在远端终止于跖趾关节的跖内侧面，此切口形成一椭圆形网球拍状组织瓣，连接于近节趾骨的基底部

Megaspore mother cells undergo meiosis, which results in the formation of 4 megaspores in a row. The chalazal-most cell develops into an 8-nuclei embryo sac after 3 rounds of mitosis. A mature embryo sac is produced after cellularization and nuclear migration.

结果表明：1大孢子母细胞经过减数分裂形成直线排列的4个大孢子，其中珠孔端的3个大孢子退化，合点端的大孢子进行3次有丝分裂，形成八核胚囊， 8个核迅速细胞化，最终发育为成熟胚囊。
