Tetraploid embryos could be produced by electrofusion at the stage of two-cell embryos, which could develop to blastcysts fellowed by fusion of cytoplasm and nucleus and cleavage in vitro.After fusion of cytoplasm, the DNA methylation levels of the fused embryos was very high as well as two-cell diploid embryos in vivo.Then the embryos was rapiddly demethylated when the nucleus begin to fuse, resulting the lowest DNA methylation levels when the nucleus fused completely.After that, the DNA methylation levels of fused embryos were gradually increased until the blastocysts stage.However, whereas an asymmetric distribution of DNA methylation was established in an vivo-derived blastocysts with a higher methylation level in the inner cell mass than in the trophectoderm, in most vitro-derived tetraploid blastocysts, we can not detect the asymmetric distribution.

结果表明：利用电融合方法制备的小鼠四倍体胚胎在体外培养体系中经历细胞质融合、细胞核融合及细胞继续分裂发育直到囊胚期的过程，在细胞质融合的时候胚胎卵裂球同体内体外培养二倍体胚胎一样，呈现高度甲基化状态；在细胞核开始融合的时候，甲基化水平急速下降，在细胞核完全融合的时候甲基化水平达到最低点；随着胚胎继续分裂，胚胎甲基化水平逐渐增加，在囊胚期甲基化水平最高；但是囊胚期四倍体胚胎内细胞团同滋养层细胞甲基化荧光信号没有差别，这与体内体外培养二倍体囊胚内细胞团细胞甲基化荧光强度高于滋养层细胞甲基化荧光强度不同。

Experimental result makes clear, the main reason that structure of revulsive bursa bubble alters exterior activator is exterior activator embeds in the double element layer of bursa bubble, the inhomogenous sex that the exterior charge intensity that changed bursa bubble thereby and the exterior activator after embedding distributing in layer of bursa bubble double element.

实验结果表明，表面活性剂诱导囊泡结构改变的主要原因是表面活性剂嵌入到囊泡的双分子层中，从而改变了囊泡的表面电荷强度以及嵌入后的表面活性剂在囊泡双分子层中分布的不均匀性。

Aeruginosa increased with the increased initial P concentration in the media;② Under the constant N concentration, the phosphorus uptake of M. aeruginosa was correlated positively with the initial P concentration;③ Under the constant P concentration, the accumulation of phosphorus by M. aeruginosa was correlated negatively with the initial N concentration, but the trend was not obvious and the effect of initial N concentration on the uptake P quantity became ruleless when the initial N concentration reached a higher level (21 mg/L).

结果显示，①氮磷比不变时，随着起始磷浓度的增加，铜绿微囊藻对正磷酸盐蓄积量也逐渐增加，成明显正相关；②氮浓度不变时，铜绿微囊藻对正磷酸盐的蓄积效果与磷浓度正相关；③而同一磷浓度下，铜绿微囊藻对正磷酸盐的蓄积效果与氮浓度负相关，但氮浓度超过21 mg/L时，氮浓度对于铜绿微囊藻蓄积磷的效果影响变得不规则。

对临床和病理证实的4例囊性肾癌，8例肾脓肿，2例肾包虫，3例肾结核，30例肾囊肿的二维超声及彩色多普勒超声表现进行了分析，对每例病灶的大小、形态、边界、囊壁回声、囊液回声、囊内分隔及彩色血流的有无、性质进行比较。

CT images of SMA5 frequently show lobulate lesions with strongly enhanced solid and cystic components. UA occurs mostly in young patients, and typically appears as cystic lesion with mild to moderate enhancement of the wall on CT images. MA often appears in old patients, and shows extensive bone destruction, soft tissue mass, ill-defined margin, and strong enhancement on CT images.

SMA多见于中年人，在CT上多表现为强化明显的囊实性肿块，边界清楚；UA常见于年轻人，在CT上表现为囊性肿物，囊壁轻中度强化；MA多见于老年患者，在CT上常显示广泛骨破坏，软组织肿块常见，强化明显，边界不清。

To evaluate the role of collagen Ⅰ,Ⅲ and Ⅳ in the formation of the pericystic layer of hepatic hydatid cyst The expression of collagen Ⅰ,Ⅲ and Ⅳ in pericystic layers of hepatic hydatid cysts from 40 patients was observed using immunohistochemical methods.

探讨Ⅰ、Ⅲ和Ⅳ型胶原在形成肝包虫囊肿周围人体纤维囊壁中的作用及其临床意义。采用免疫组织化学方法检测Ⅰ、Ⅲ和Ⅳ型胶原在40例肝包虫囊肿周围纤维囊壁中表达。Ⅰ、Ⅲ和Ⅳ型胶原在肝包虫囊肿周围纤维囊壁中出现特异性分层表达。

假性囊膜剥脱综合症，核硬度，瞳孔大小，超声时间，实际超声时间，系统性疾病，术中并发症(囊膜撕裂，悬韧带断裂，后囊破裂伴玻璃体丢失)，IOL植入位置和术后并发症作为膜形成的危险因素分析。

Cysticercus ellulosae could live in liver not only in muscle as we thought before. During the fast process of sending pigs to go into the market, it should be aware that even though cysticerci are not found in liver, they may be still in suitable locations of muscles, and more attention should be paid to pig quarantine.

猪囊尾蚴除在四肢肌肉等主要寄生部位生长外，还可以在猪的肝脏内寄生，但是随感染时间增加会逐渐死亡和钙化，表明在当前生猪快速出栏养殖过程中，猪肝脏无囊尾蚴寄生时，其余主要寄生部位如四肢和驱干肌肉内仍有囊尾蚴寄生，提示在生猪检验检疫工作中应予以重视。
