Factors affecting the efficiency of nuclear transfer （NT） in rabbits were examined in the present study. When 100 V mm of pulse strength and 15 us of pulse duration were employed, 3 and 4 electronic pulses resulted in significantly more cytoplasts fused with donor cells compared with 2 electronic pulses （P〈 0.05）, but no significant difference was found in the cleavage rate of reconstructed embryos among the three groups （P〉0.05）. When the duration and number of electronic pulse were fixed at 15 ps and 3 times, increase of pulse intensity from 100 V mm 1 to 150 V mm^-1 and 200 V mm^-1 resulted in a significantly decrease in the cleavage rate of reconstructed embryos （P〈 0.05）, although the fusion rate did not significantly differ among the three groups （P〉 0.05）. Significantly more reconstructed embryos cleaved and developed to blastocysts when they were derived from donor embryos at the 8-16-cell stage, in comparison with the reconstructed embryos derived from donor embryos at the compact morula stage （P 〈 0.05）, although the fusion rate was similar （P 〉 0.05）. Activation of cytoplasts prior to fusion increased the cleavage rate （P〈 0.05） and blastocyst development （P〈 0.05） of reconstructed embryos, but decreased the fusion rate （P 〈 0.05） compared with cytoplasts activated post fusion. More reconstructed embryos developed to blastocysts when they were cultured in TCM ＋ 3% OCS at the first 48 h and then cultured in TCM199＋ 10% FCS, in comparison with the reconstructed embryos cultured in either TCM199＋ 10% FCS or TCM199＋3% OCS （P 〈 0.05）. When 22 NT embryos were transferred into the oviducts of one recipient rabbit, one recipient rabbit delivered a female rabbit at 34 days of gestation. In conclusion, either electrofusion parameter or developmental stage of donor embryos have a significant effect on the efficiency of NT, NT embryos require different concentration of serum at their different development stages.

对兔胚胎细胞核移植(NT)的有关影响因素进行了系统研究。结果发现电场强度100V·mm-1,脉冲时间15μs,电脉冲3～4次的融合率显著高于其它组(P<0.05);融合前激活卵母细胞,分裂率和囊胚率显著高于融合后激活(P<0.05);当用8～16-细胞胚胎的卵裂球作供核时,卵裂率和囊胚率显著高于致密桑椹胚卵裂球为供核组;当重组胚在含3%发情牛血清(OCS)的TCM199中培养48h后,转入含10%FCS的TCM199中继续培养,卵裂率和囊胚率显著高于一直在3%OCS或10%胎犊血清(FCS)中培养的重组胚(P<0.05)。将22枚2～4-细胞期重组胚移入同期发情的受体母兔输卵管内,34d后产下NT仔兔1只。结果表明,电融合参数和供体胚胎的发育阶段以及受体卵母细胞的状态对NT效果有显著影响,在NT胚胎的不同发育阶段采用不同的血清种类和浓度可提高其胚胎发育能力。

We present the observational results from a detailed timing analysis of the black hole candidate EXO 1846-031 during its outburst in 2019 with the observations of Insight-HXMT,NICER and *** outburst can be classified roughly into four different ***-C quasi-periodic oscillations(QPOs)observed by NICER(about 0.1-6 Hz)and Insight-HXMT(about 0.7-8 Hz)are also reported in this ***,we study various physical quantities related to QPO *** QPO rms-frequency relationship in the energy band 1-10 keV indicates that there is a turning pointing in frequency around2 Hz,which is similar to that of GRS 1915+105.A possible hypothesis for the relationship above may be related to the inclination of the source,which may require a high inclination to explain *** relationships between QPO frequency and QPO rms,hardness,total fractional rms and count rate have also been found in other transient sources,which can indicate that the origin of type-C QPOs is non-thermal.

本研究旨在克隆水牛MBD3基因,进行生物信息学分析,并构建MBD3基因的真核表达载体,为研究MBD3基因在水牛胚胎发育及诱导多能干细胞(iPSCs)中的作用奠定基础。试验从卵巢组织中提取总RNA,反转录得到cDNA,并以此为模板,应用RT-PCR克隆得到MBD3基因,测序并应用相关的生物学软件进行分析;将MBD3基因连接至真核表达载体pEGFP-C1,再将携带目的基因的重组质粒转染HEK293T细胞和水牛胎儿成纤维细胞(BFF),利用RT-PCR及Western blotting方法分析目的基因的表达。结果表明,克隆获得了898bp的水牛MBD3基因序列,其中编码区全长774bp,编码257个氨基酸。通过对MBD3基因核苷酸序列的多重比对及进化树分析,MBD3基因在进化中高度保守,特别是MBD结构域,水牛与牛的同源性为100%,与人、猪、猩猩的同源性均为97%。将水牛MBD3基因真核表达载体转染HEK293T细胞和BFF,通过荧光观察、RT-PCR及Western blotting方法鉴定表明,成功构建了水牛MBD3基因的真核表达载体。本研究克隆得到了水牛的MBD3基因,并成功构建了MBD3基因的真核表达载体,为进一步研究MBD3基因在水牛胚胎发育及iPSCs诱导上的作用奠定了基础。

2018年3月8?9日,中国临床肿瘤学会(Chinese Society of Clinical Oncology,CSCO)和中国抗癌协会肺癌专业委员会联合主办了第15届“中国肺癌高峰论坛”。本次论坛的主题为“聚焦中枢神经系统转移:精确诊断,精准治疗”。晚期肺癌患者往往合并脑转移,在1 000多例的肺癌尸检结果中,肺癌脑转移发生率23%~36%,是脑转移性肿瘤中最常见的类型,且通常预后较差[1]。目前肺癌脑(膜)转移的综合治疗管理和治疗结果,仍不令人满意,治疗效果不佳,中位总生存时间16个月,其中脑膜转移的患者则仅为4.5个月左右[2?5]。近10年肺癌的治疗出现了革命性的改变,但肺癌脑转移的诊断和治疗成了提高肺癌长期生存率的瓶颈。临床医师及科研工作者,应如何对脑转移进行准确及时的诊断?在众多的分型分类体系中,又该如何参考应用?如何全面地对脑转移患者的颅内/颅外病灶进行合理评估?对于伴有驱动基因敏感突变的脑转移患者群体,应怎样对待酪氨酸激酶抑制剂(tyrosine kinase inhibitor,TKI)治疗的定位和应用时机?随着血管生成抑制剂和免疫检查点Checkpoint抑制剂的应用发展,新的治疗选择在肺癌脑转移治疗应用中又该如何管理?以上都是肺癌脑转移综合管理中的疑点和难点,急需解答和形成共识以指导临床实践。本次肺癌高峰论坛,综合近年来发表的前瞻性及回顾性重要研究结果、结合我国肺癌脑转移治疗管理的实际情况,与会专家们就肺癌脑转移的综合管理进行了详细的讨论和各抒己见的争辩,最后达成了以下四点共识。
