BACKGROUND Pancreatitis is a severe inflammatory pancreatic disease commonly due to bile duct stones or excessive alcohol usage,with clinical manifestations of abdominal pain,nausea,fever,and fluid collections.Healthy persons with less symptomatic pancreatitis are quite rare.Herein,we report a case of a patient with an undetermined onset of pancreatitis mimicking left arm cellulitis due to thrombotic vasculitis of the brachiocephalic vein.CASE SUMMARY A 50-year-old woman visited our hospital for tenderness in the left arm over several recent days.She was diagnosed with cellulitis on the left arm due to left elbow tenderness.Intravenous antibiotics administration did not improve symptoms and laboratory data worsened;thus,chest and abdominal computed tomography(CT)was performed.CT demonstrated pancreatitis with pseudocyst around the pancreas extending to the mediastinum.Thrombotic vasculitis of the brachiocephalic to left brachial vein was observed,which could be the cause of left elbow pain.A pancreatic fistula was found in the head of the pancreas by endoscopic retrograde cholangiopancreatography,so a pancreatic cyst drainage tube via the duodenum was placed in the pseudocyst.Cyst content culture was positive for Escherichia coli infection.Clinical symptoms,imaging findings,and inflammatory reactions resolved gradually after starting therapeutic intervention.The mediastinal pancreatic pseudocysts shrunk,and the venous thrombi remained but shrunk.CONCLUSION The case of a patient with pancreatitis with an undetermined onset that mimics left arm cellulitis is reported.Deep vein thrombosis should be kept in mind when treating patients with severe inflammatory disease.

Diffusion-weighted imaging of the liver:Current applications

引用

World Journal of Radiology 2016年第11期8卷 857-867页

作者： Kazuhiro Saito yu tajima Taiyo L Harada Department of Radiology Tokyo Medical University

Diffusion-weighted imaging(DWI) of the liver can be performed using most commercially available machines and is currently accepted in routine sequence. This sequence has some potential as an imaging biomarker for fibrosis, tumor detection/characterization, and following/predicting therapy. To improve reliability including accuracy and reproducibility, researchers have validated this new technique in terms of image acquisition, data sampling, and analysis. The added value of DWI in contrastenhanced magnetic resonance imaging was established in the detection of malignant liver lesions. However, some limitations remain in terms of lesion characterization and fibrosis detection. Furthermore, the methodologies of image acquisition and data analysis have been inconsistent. Therefore, researchers should make every effort to not only improve accuracy and reproducibility but also standardize imaging parameters.

欧拉羊(Oula sheep)属于藏羊(Tibetan sheep)的一个分支。不同于其他国内外绵羊(Ovis aries)品种,欧拉羊的公母羊皆生有大犄角。这是长期放牧条件下自然选择的结果,但其大犄角不利于现代高效畜牧业生产需求。已有较多研究把绵羊无角性状的主效控制基因定位于绵羊10号染色体上的RXFP2基因,但RXFP2基因在不同绵羊品种中的调控作用仍有差别。为加快青藏高原地区无角绵羊品种培育,本研究对青海有角型、无角型欧拉羊成年母羊各15只进行了10×深度的基因组重测序,采用F_(ST)选择性消除定位角表型主要选择基因,并对欧拉羊RXFP2基因CDS区域及上下50 kbp区域以2000 bp窗口、1000 bp步长进行扫描,对获得的单核苷酸多态性(single nucleotide polymorphism,SNP)进行tajima′s D、π、FST选择分析。结果发现,欧拉羊RXFP2基因及3′下游区域存在强选择信号。通过对RXFP2基因编码区SNP筛选,挖掘了欧拉羊中4个高质量SNPs,分别是位于RXFP2基因第9、第14外显子的同义突变(g.29458690A>G,g.29446067T>C)和第17外显子的2个非同义突变(g.29439053C>T,g.29439011C>T);突变区域均处于无角、有角欧拉羊RXFP2基因的强选择区域。本研究结果可为无角欧拉羊品种(品系)培育相关分子辅助选择工作提供技术和理论依据,有助于加快无角欧拉羊品种培育的早期选种工作。

【目的】番茄潜叶蛾Tuta absoluta(Meyrick)是番茄作物上的重大害虫,自入侵我国以来,已经造成了严重的经济损失,因此为了追踪我国番茄潜叶蛾的遗传分化进程,分析其与世界其它地理种群的遗传关系,本研究对番茄潜叶蛾种群的遗传结构进行了分析。【方法】研究采用线粒体COⅠ基因作为分子标记,分别对COⅠ基因同源性、遗传变异、遗传多样性、生物分子变异组成进行了分析,最后构建了世界范围内的系统发育树。【结果】结果显示,我国甘肃和宁夏地区的地理种群已经发生了可遗传变异,其中甘肃出现了两种突变单倍型(China:GSLZ;China:GSLZ),宁夏为一种突变单倍型(China:NXWZ);全球番茄潜叶蛾地理种群共检测到28个多态位点,存在18种单倍型,以塞内加尔地理种群单倍型最丰富,达10种,其次为肯尼亚;我国地理种群存在2个转换突变的简约信息位点,共3种单倍型,推测我国番茄潜叶蛾已经形成了一定的群体结构,但仍然处于入侵“瓶颈期”;总体而言,非洲番茄潜叶蛾遗传多样性最高,其次分别为南美洲和亚洲;分子生物学方差分析显示,引起种群变异的主要因素存在于种群内部,变异率占97.99%。系统发育分析表明,全球番茄潜叶蛾总体可以分为4个类群,以肯尼亚地理种群的变异种遗传距离较远,但我国甘肃兰州和宁夏两个地理种群突变种与肯尼亚KU565664.1突变种为同一单倍型,其它地理种群变异种均聚类在相同遗传发育节点之下。【结论】世界范围内番茄潜叶蛾单倍型多样性与核苷酸多样性等遗传多样性指标均较低,种群遗传具有高度同质性,但非洲番茄潜叶蛾的遗传多样性较高。在我国,番茄潜叶蛾种群在线粒体DNA分子水平上已经发生了明显分化,主要为C/T(China:GSLZ)和A/G(China:GSZY)转换突变。

菜粉蝶Pieris rapae是十字花科蔬菜重要的农业害虫。为了深入了解中国菜粉蝶的群体遗传特征,通过高通量测序获取了中国5个群体48头菜粉蝶的线粒体全基因组,并分析了不同群体间的遗传结构与多样性。结果表明:菜粉蝶群体间有较高的线粒体单倍型多样性;相对封闭的山区和盆地地区的核苷酸多样性较低;群体间的平均遗传分化指数(F_(ST))仅0.042,表明不同群体间的遗传分化水平较低,这也暗示了群体间基因交流频繁,推测这与甘蓝等蔬菜频繁运输有关;线粒体进化树和网络图均未形成明显的地理谱系,南北方群体之间没有明显的遗传结构差异;总群体的tajima's D和Fu's Fs值均为负值,且达到了显著水平,这意味着中国地区的菜粉蝶可能经历过群体扩张事件。

Widespread species that inhabit diverse environments possess large population sizes and exhibit a high capacity for environmental adaptation,thus enabling range expansion.In contrast,narrow-range species are confined to restricted geographical areas and are ecologically adapted to narrow environmental conditions,thus limiting their ability to expand into novel environments.However,the genomic mechanisms underlying the differentiation between closely related species with varying distribution ranges remain poorly understood.The Niviventer niviventer species complex(NNSC),consisting of highly abundant wild rats in Southeast Asia and China,offers an excellent opportunity to investigate these questions due to the presence of both widespread and narrow-range species that are phylogenetically closely related.In the present study,we combined ecological niche modeling with phylogenetic analysis,which suggested that sister species cannot be both widespread and dominant within the same geographical region.Moreover,by assessing heterozygosity,linkage disequilibrium decay,and tajima's D analysis,we found that widespread species exhibited higher genetic diversity than narrow-range species.In addition,by exploring the“genomic islands of speciation”,we identified 13 genes in highly divergent regions that were shared by the two widespread species,distinguishing them from their narrow-range counterparts.Functional annotation analysis indicated that these genes are involved in nervous system development and regulation.The adaptive evolution of these genes likely played an important role in the speciation of these widespread species.

Involuntary muscle spasm expressed as motor evoked potential after olfactory mucosa autograft in patients with chronic spinal cord injury and complete paraplegia

引用

Journal of Biomedical Science and Engineering 2013年第9期6卷 908-916页

作者： Koichi Iwatsuki Toshiki Yoshimine Yoshiyuki Sankai Fumihiro tajima Masao Umegaki yu-Ichiro Ohnishi Masahiro Ishihara Koshi Ninomiya Takashi Moriwaki Department of Neurosurgery Osaka University Medical SchoolOsakaJapan Faculty of Engineering‚Information and Systems University of TsukubaTsukubaJapan Department of Rehabilitation Wakayama Medical UniversityWakayamaJapan

Object: The efficacy of olfactory mucosa autograft (OMA) for chronic spinal cord injury has been reported. New activity in response to voluntary effort has been documented by electromyography (EMG), but the emergence of motor evoked potential (MEP) reflecting electrophysiological conductivity in the central nervous system, including the corticospinal pathway, after OMA, and the best indications for OMA, have not been clarified. Here, we report the emergence of MEPs after OMA and offer recom-mendations for appropriate indications based on the presence of involuntary muscle spasm (IMS). We used analysis of MEP to examine the efficacy of OMA for patients with complete paraplegia due to chronic spinal cord injury. To clarify the indications for OMA, we investigated the association of IMS and efficacy of OMA. Methods: Four patients, 3 men and 1 woman, were enrolled. The mean age of the cases was 30.3 ± 9.5 years (range, 19 to 40 years). All 4 cases were American Spinal Injury Association (ASISA) grade A. The mean duration from injury to OMA was 95.8 ± 68.2 months (range, 17 to 300 months). Samples of olfactory mucosa were removed, cut into smaller pieces, and grafted into the sites of spinal cord lesions after laminectomy. Postoperative subcutaneous fluid collection, postoperative meningitis, postoperative nosebleed, postoperative infection in the nasal cavity, impaired olfaction, neoplastic tissue overgrowth at the autograft site, new sensory disturbance, and involuntary muscle spasm were investigated as safety issues. Improvements in ASIA grade, variations in ASIA scores, EMG, SSEP, and improved urological function were evaluated as efficacy indicators. Results: There were no serious adverse events in this series. In 2 of the 4 cases, an improvement in motor function below the level of injury was recognized. In one, the motor score was 50 until 16 weeks after surgery, and it increased to 52 from 20 weeks after surgery. In the other, the motor score was 50 until 20 weeks after surgery, and it increased to 52 at 24 we

Journal of Integrative Agriculture 2013年第6期12卷 1033-1041页

作者： LIU yu-di HOU Mao-lin WU yu-chun LIU Gui-qin State Key Laboratory for Biology of Plant Diseases and Insect Pests/Institute of Plant Protection Chinese Academy of Agricultural Sciences Guangdong Provincial Public Laboratory on Wild Animal Conservation and Management Guangdong Entomological Institute

Genetic variation and patterns of genetic differentiation of the rice stem borer, Chilo suppressalis （Lepidoptera： Pyralidae）, from the South China were analyzed using 6 microsatellite markers and two partial mtDNA （cox1 and cox2） regions. All of the 6 microsatellite loci were polymorphic in the studied seven populations. The allelic richness per population ranged between 5.67 and 14.00, and average H E and H O values were 0.6246-0.8329 and 0.2634-0.6061, respectively. As the mitochondrial genome is a single genetic locus, we only present results for the concatenated data set （cox1 plus cox2 gene sequences, 513 bp）. The concatenated data showed high level of genetic diversity and there are 23 variable polymorphic sites among the 513 sites in concatenated data. Nearly all of （20 of 21） pairwise F ST comparisons among populations showed genetic differentiation with moderate to high pairwise F ST values based on microsatellite markers. However, for the mtDNA data, most of the seven populations did not show significant differentiation with other populations. The differences of population differentiation obtained with the two different genetic markers could be mainly attributed to the different mutation rates of microsatellite and mtDNA. There was not genetic structure existed in these studied populations based on microsatellite loci and mtDNA data. The analysis based on network, mismatch distribution, tajima＇s D and F S indicated that the studied populations were from the recent same ancestor or the same refuge and followed by a sudden demographic expansion condition.
