The rapid development of high-throughput sequencing technologies has led to a dramatic decrease in the money and time required for de novo genome sequencing or genome resequencing projects, with new genome sequences constantly released every week. Among such projects, the plethora of updated genome assemblies induces the requirement of versiondependent annotation files and other compatible public dataset for downstream analysis. To handlethese tasks in an efficient manner, we developed the reference-based genome assembly and annotation tool（RGAAT）, a flexible toolkit for resequencing-based consensus building and annotation update. RGAAT can detect sequence variants with comparable precision, specificity, and sensitivity to GATK and with higher precision and specificity than Freebayes and SAMtools on four DNAseq datasets tested in this study. RGAAT can also identify sequence variants based on cross-cultivar or cross-version genomic alignments. Unlike GATK and SAMtools/BCFtools, RGAAT builds the consensus sequence by taking into account the true allele frequency. Finally, RGAAT generates a coordinate conversion file between the reference and query genomes using sequence variants and supports annotation file transfer. Compared to the rapid annotation transfer tool（RATT）,RGAAT displays better performance characteristics for annotation transfer between different genome assemblies, strains, and species. In addition, RGAAT can be used for genome modification,genome comparison, and coordinate conversion. RGAAT is available at https://***/projects/rgaat/and https://***/wushyer/RGAAT;2 at no cost.

浮游藻类是水生态系统的重要初级生产者,对其进行分类鉴定和定量分析是开展生态研究的基础。选取北京城区主要河流为研究对象,于2020年6—7月(夏季)、10月(秋季)对北运河水系22个站位的表层水进行采样调查,探究利用流式影像术(FlowCAM)分析浮游藻类群落结构的可行性。结果表明,浮游藻类的细胞丰度和粒径组成均存在着明显的时空差异。多数站位在夏季的优势属个数明显高于秋季,且随着季节的变动,优势属的物种组成由以硅藻为主转变为以蓝藻或蓝藻-绿藻为主。利用FlowCAM可以快速完成对浮游藻类的计数、粒径分级和对小型浮游藻类的识别鉴定。该技术在水生态监测方面有很大的应用空间,但还存在微型浮游藻类图像分辨率较低、无法完全自动分类等缺陷。

背景与目的中国是肺癌高发地区,其发病率及死亡率在恶性肿瘤中均占首位。目前低剂量CT检查的普及使早期肺癌检出率显著提高,解剖性肺段切除目前广泛应用于Ia期非小细胞肺癌(non-small cell lung cancer,NSCLC)及不能耐受肺叶切除肺癌患者。但因肺段解剖结构及手术操作相对复杂,使得其具有较高的手术风险与难度。我们应用三维计算机断层扫描支气管血管成像(three-dimensional computed tomography bronchography and angiography,3D-CTBA)及三维电视辅助胸部外科技术(three-dimensional video-assisted thoracic surgery,3D-VATS)单操作孔行解剖性肺段切除微创手术技术治疗NSCLC,以探讨其临床效果,为其临床应用提供相关可行性及理论依据。方法回顾性分析苏州大学附属第一人民医院胸外科2015年10月-2017年04月共施行57例术前对肺部病灶予以3D-CTBA重建以及术中应用3D-VATS单操作孔进行解剖性肺段切除治疗NSCLC病例。结果全组均全腔镜下顺利完成,无中转开胸。手术时间平均(142.2±28.3)min,术中出血量平均(93.8±46.5)m L。平均淋巴结清扫数目(9.1±2.2)个,术后胸腔引流量平均(429.8±181.2)m L。术后留置胸管时间(2.8±1.1)d。平均住院时间(5.2±1.3)d。术后病理示良性病变9例,约占15.7%,恶性病变48例,约占84.2%。术后并发症:肺部感染3例(5.2%),肺不张1例(1.7%),少量咯血1例(1.7%),肺漏气2例(>3 d,3.5%),心律失常4例(7.0%)。术后平均随访10个月,无支气管胸膜瘘、乳糜胸、包裹性胸腔积液等并发症,随访患者中无复发及远处转移病例。结论应用3D-CTBA及3D-VATS单操作孔行解剖性肺段切除治疗NSCLC的安全有效,适用于早期NSCLC以及不能耐受肺叶切除患者。
