摘要： 教学评价体系改革，对推进高校教学改革，提高学生的综合素质和能力具有十分重要的导向作用^[1]。传统的教学评价只注重终结性评价，以学生的期末考试成绩作为教学评价的唯一指标，这种评价方式忽略了教学过程，学生只是被动的评价客体，造成学生对教师的依赖，在很大程度上忽视了学生在学习中的主体性、能动性和创造性，直接影响了学生的学习兴趣和教学效果。

摘要： 目的构建上皮组织特异性表达鼻咽癌来源潜伏膜蛋白1(N-LMP1)和人补体受体2(CR2)真核表达载体,转染猪胚胎成纤维细胞并筛选整合有N-LMP1和CR2基因的细胞克隆,为构建与EBV感染相关的猪鼻咽癌模型奠定基础。方法通过直接合成ED-L2启动子和N-LMP1,从人B淋巴细胞中的RNA经RT-PCR扩增出CR2,将上述3个片段逐个连接到真核表达载体pN1上,构建上皮组织特异性表达N-LMP1和CR2的载体pN1-EDL2-N-LMP1-CR2;用脂质体转染猪胚胎成纤维细胞,经药物G418筛选和PCR鉴定阳性克隆。结果成功构建上皮组织特异性表达N-LMP1和CR2的真核表达载体pN1-ED-L2-N-LMP1-CR2,并成功整合到猪胚胎成纤维细胞的基因组中,获得了整合有目的基因N-LMP1和CR2的猪胚胎成纤维细胞克隆。结论获得了上皮组织特异性表达N-LMP1和CR2的猪胚胎成纤维细胞克隆,为通过细胞核移植方法获得表达N-LMP1和CR2转基因猪提供了供体细胞。

摘要： Is post-implantation embryonic development after blastocyst transfer affected by exposure to different assisted reproduction technology (ART) culture media? Fetal development and placental histology of ART embryos cultured in vitro in different ART media was not impaired compared with embryos grown in vivo. The application of different in vitro culture (IVC) media for human ART has an effect on birthweight of newborns. In the mouse model, differences in blastocyst formation were reported after culture in different ART media. Moreover, abnormalities in the liver and heart have been detected as a result of suboptimal IVC conditions. Fertilized oocytes from inbred and outbred breeding schemes were retrieved and either immediately transferred to foster mothers or incubated in control or human ART culture media up to the blastocyst stage prior to transfer. Placental and fetal anatomy and particularly bone development were evaluated. B6C3F1 female mice were used as oocyte donors after ovulation induction. C57Bl/6 and CD1 males were used for mating and CD1 females as foster mothers for embryo transfer. Fertilized oocytes were recovered from mated females and incubated in sequential human ART media (ISM1/ISM2 and HTF/Multiblast), in control media [KSOM(aa) and Whittens medium] or grown in utero without IVC (zygote control). As in vivo, control B6C3F1 females were superovulated and left untreated. Fetuses and placentae were isolated by Caesarean section and analysed at 18.5 days post-coitum (dpc) for placenta composition and at 15.5 dpc for body weight, crownrump length (CRL), fetal organ development, morphological development, total bone length and extent of bone ossification. No major differences in the number of implantation sites or in histological appearance of the placentae were detected. CRL of KSOM(aa) fetuses was higher compared with zygote control and Whittens medium. Histological analysis of tissue sections revealed no gross morphological differences compared with

摘要： The role of the choroid plexus in cerebrospinal fluid production has been identified for more than a century. Over the years, more intensive studies of this structure has lead to a better understanding of the functions, including brain immunity, protection, absorption, and many others. Here, we review the macro- and microanatomical structure of the choroid plexus in addition to its function and embryology. The literature was searched for articles and textbooks for data related to the history, anatomy, physiology, histology, embryology, potential functions, and surgical implications of the choroid plexus. All were gathered and summarized comprehensively. We summarize the literature regarding the choroid plexus and its surgical implications.
