This result indicates that WT1 gene plays an important role in differentiation and development of fetal kidney and may be the factor that promotes metanephric blastemal cell to differentiate into epithelial cell.

结果显示小胎龄肾组织中WT1蛋白在胚基细胞和幼稚肾小球细胞核表达而大胎龄组肾组织中WT1在肾小管细胞胞浆表达，阳性率分别为57.1％(8/14)和46.2%(6/13)，提示WT1基因在胚胎肾分化发育的过程中起着重要作用，WT1蛋白可能是促进后肾胚基细胞向上皮细胞分化的调控因子，其表达在时间上和空间上都受到严格的调控，WT1的表达异常可能导致胚基细胞分化停滞。17例肾母细胞瘤WT1蛋白表达阳性率为41.2%(7/17)，阳性部位在胚基型和上皮型肿瘤细胞核，表达部位和阳性率与早期胚胎肾相似，其中间质型肾母细胞瘤均为阴性，胚基型和上皮型肾母细胞瘤阳性率70%(7/10)，两组间阳性率有显著差异。

But a few cases, compared with benign, such as muscle blastoma, chondroblastoma and osteoblastoma.

但少数情况则为良性，如肌母细胞瘤、软骨母细胞瘤和骨母细胞瘤。

The duration and temperature during ovary transportation and handling might, therefore, affect the recovery of culturable COCs, chromatin configuration and developmental competence of oocytes.

在具体的实施过程中，从屠宰场向实验室运输卵巢、卵母细胞培养前操作等都需要一定的时间，这可能会对卵母细胞的回收率、卵母细胞成熟质量、甚至受精后的发育产生不良影响。

According to the above evaluation of immuno-epidemiology of RSA, RSA may be etiologically classified into lack of materno-fetal immuno-recognition, materno-fetal inappropriate immuno-recognition, and disorder of materno-fetal immuno-recognition.

根据RSA免疫流行病学分析，RSA的病因可以分类为：母-胎免疫识别低下型、母-胎免疫识别过度型及母-胎免疫识别紊乱型。

After that , the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article , in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos .

和胞浆内单精子注射两种方法对玻璃化冷冻卵母细胞的受精能力进行了比较研究，旨在建立能够进一步提高牛冷冻卵母细胞受精能力的改进方案，使卵母细胞冷冻技术上升到与胚胎冷冻同样成熟的水平。

Rising of fertilization membrane during induced maturation indicates insemination is not necessary to form the fertilization membrane. The oocyte will not become fertilizable until GVBD has happened and can still be fertilized after the second polar body extrusion.

卵母细胞只有在生发泡破裂之后才具有受精能力，从生发泡破裂到第二极体排出前的整个减数分裂过程中，卵母细胞都可以受精，但是只有在第一极体排出前受精的卵母细胞才能发生卵裂。

After that, the comparison of the fertilizable competences of ICSI and IVF on cryopreservated oocytes was studied in this article, in order to establish an optimized method to improve the fertilizable competences of oocytes up to the level of embryos.1 Effects of the reducing injury methods on IVF of cryopreservated oocytesThe result of the three methods, choosing the right time oocytes, using minimum size sample vitrification and culturing after thawing, showed that these ways could partly maintained the fertilizable competences of cryopreservated bovine oocytes.

减轻损伤方案对冷冻卵母细胞IVF的影响使用选择合适时期的卵母细胞进行冷冻；采用最小样本量玻璃化冷冻方法进行冷冻；在解冻后先孵育再进行体外受精等三种方案能够部分维持或恢复冷冻牛卵母细胞IVF受精能力。

Results All the 7 cases were female, 2 cases were solitary fibrous tumor, 2 cases were myofibroblastoma, 1 case was inflammatory myofibroblastic tumour, 1 case was fibromatosis, and 1 case was low grade myofibroblastic sarcoma.

结果 7例患者均为女性，2例为孤立性纤维性肿瘤；2例为肌纤维母细胞瘤；1例为纤维瘤病；1例为炎性肌纤维母细胞瘤；1例为低度恶性肌纤维母细胞肉瘤。

Results By univariate analysis 11 risk factors were explored: family poverty, low culture level of mother, history of family on MR or epilepsy in parents, abnormal maternal menstrual cycle before pregnancy, febrile illess during gestation, bleeding in gestation period, chronic disease in gestation period, premature birth, assisted first crying after birth, neonatal febrile illness, convulsion and asphyxiation.

结果单因素分析儿童MR的危险因素有：家庭贫困、母亲文化程度低、父母亲智力低下或癫痫家族史、母亲妊娠前月经周期异常、母孕期发热、母孕期出血、母孕期患有慢性病、早产、出生后第一声啼哭是否需辅助、新生儿发热、惊厥、窒息。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
