作为一种快速、高灵敏的挥发性有机物(VOCs)检测技术,质子转移反应质谱(PTR-MS)被越来越多地应用于环境、医学、公共安全等领域。作为PTR-MS的关键部件之一,空心阴极辉光放电离子源对仪器性能具有重要影响。本文通过有限元仿真优化了空心阴极结构,在阴极内径为20 mm、阳极与阴极间隙为4 mm时,离子源放电效果较好。将优化后的空心阴极辉光放电离子源与便携式质谱仪联用,并测试了离子信号与放电气压和放电电流的关系。结果表明,最佳放电气压约为200 pa.最佳放电电流为9~13 m A。采用乙腈样品测试了仪器性能,系统响应时间在10 s以内,乙腈检出限约为10^(-9)(V/V),线性范围为50×10^(-9)~350×10^(-9)(V/V),线性相关系数R^(2)=0.991。利用该装置检测了苹果发酵过程中产生的VOCs随时间的变化,证明了该仪器可用于实际样品检测。

Human endogenous retroviruses: ammunition for myeloid cells in neurodegenerative diseases?

Neural Regeneration Research 2020年第6期15卷 1043-1044页

作者： Joel Gruchot David Kremer pa.rick Küry Depa.tment of Neurology NeuroregenerationMedical FacultyHeinrich-Heine-University

Activation of myeloid cells by human endogenous retroviral entities:While the exact causes of neurological diseases such as multiple sclerosis(MS)or amyotrophic lateral sclerosis(ALS)are still elusive,there is evidence of a new category of pa.hogenic elements called human endogenous retroviruses(HERVs)which seem to contribute to their evolution and progression by exerting inflammatory and degenerative effects(Kury et al.,2018).HERVs are ancient retroviral elements which account for up to 8%of the human genome and it is known that environmental factors can trigger their(re-)expression(Kury et al.,2018).The resulting production of viral pa.ticles and/or proteins,especially from members of the HERV-W and HERV-K family,is strongly correlated with the onset and progression of neurological diseases,such as MS and ALS(Kury et al.,2018).

目的分析甲状腺乳头状癌(PTC)患者对侧中央区淋巴结(Cont-CLNs)转移的相关因素,评估颈中线淋巴结(Mid-CLNs)分区在识别Cont-CLNs转移中的临床价值。方法选取2021年1月至2023年6月广东省佛山市第一人民医院进行甲状腺全切除术和双侧中央区颈淋巴清扫术(CND)治疗PTC的125例患者,组织病理学检查评估的主要因素包括:原发肿瘤最大直径、多灶性、被膜侵犯、腺外浸润、桥本氏甲状腺炎、淋巴结转移分区。组间数据比较采用单因素方差分析。利用多因素Logistic回归分析法分析Cont-CLNs转移的危险因素,计算受试者工作特征(ROC)曲线下面积,分析对侧Mid-CLNs转移对Cont-CLNs转移的预测效能。结果125例PTC患者中,107(85.60%)例患者发生Mid-CLNs转移,57.60%(72/125)的患者发生患侧Mid-CLNs转移,28.80%(36/125)的患者发生对侧Mid-CLNs转移。在单因素分析中,多灶性(P=0.004)、被膜侵犯(P=0.002)、腺外浸润(P=0.048)、对侧Mid-CLNs转移(P<0.01)和Ipis-CLNs转移(P=0.043)与Cont-CLNs转移的发生有显著相关性。而Mid-CLNs转移(P=0.422)、患侧Mid-CLNs转移(P=0.856)与Cont-CLNs转移的发生则无相关性。多因素Logistic回归分析发现,Ipis-CLNs转移(P=0.013,OR=2.065)和对侧Mid-CLNs转移(P=0.008,OR=2.072)发生越多,Cont-CLNs转移发生的概率越大。且对侧Mid-CLNs转移阳性对Cont-CLNs转移预测的AUC为0.664(95%CI=0.554~0.774,P=0.006),敏感度为76.19%,特异度为56.60%。结论对侧Mid-CLNs转移是Cont-CLNs转移的独立危险因素,且对预测Cont-CLNs转移具有较为良好的诊断价值。

Identification of <i>JAK2</i>(V617F) Mutation in Myeloproliferative Neoplasms by Using Allele Specific Polymerase Chain Reaction (AS-PCR)

引用

American Journal of Molecular Biology 2020年第4期10卷 273-282页

作者： Khin la Pyae Tun Aung Zaw latt Win pa.pa.Naing San San Htwe Yamin Ko Ko Win Win Mar San Yu Hlaing Wai Wai Han Sein Win Depa.tment of Medical Research Yangon Myanmar Depa.tment of Clinical Haematology Yangon General Hospital Ministry of Health and Sports Nay Pyi Taw Myanmar

Myeloproliferative neoplasms (MPNs) are a group of clonal haematopoietic stem cell disorders characterized by the proliferation of one or more myeloid cell lineages. According to WHO classification, the Janus associated kinase 2 (JAK2) V617F mutation is one of the major diagnostic criteria in BCR-ABL1 negative myeloproliferative neoplasms. The aim of this study is to detect the JAK2 (V617F) mutation in pa.ients with myeloproliferative neoplasms to get accurate diagnosis and proper management. A total of 90 clinically diagnosed MPN pa.ients attending to Depa.tment of Clinical Haematology, Yangon General Hospital were enrolled in this study. The mean age was 53.4 ± 14 years which ranged from 16 to 81 years old and male and female ratio was 2.4:1. The identification of JAK2 (V617F) point mutation was found to be positive in 44/90 MPN pa.ients (48.9%). According to MPN subtypes, the JAK2 mutation positivity was found in 19 out of 46 polycythemia vera pa.ients (41.3%), 17 out of 25 essential thrombocythemia pa.ients (68%), 8 out of 15 primary myelofibrosis pa.ients (53.3%), 0 of 4 others myeloproliferative neoplasms (0%). Confirmation of each of nine JAK2 mutation positive and negative samples was done by Sanger sequencing. The arterial or venous thrombotic attack was found in 32/44 JAK2 mutation positive cases (72.7%) and 12/44 JAK2 mutation negative cases (27.3%). The association between thrombotic attack and presence of JAK2 mutation was statistically significance with p = 0.000. The diagnosis of myeloproliferative neoplasms mainly relies on the molecular genetics according to WHO classification. The Allele specific PCR reaction is sensitive, simple test and relatively cost-effective. Therefore, the identification of JAK2 (V617F) somatic point mutation by AS-PCR should be implemented as

Chasing the queens of the alien predator of honeybees: A water drop in the invasiveness ocean

Open Journal of Ecology 2012年第4期2卷 183-191页

The Yellow-legged hornet, Vespa.velutina , was accidentally introduced in France in 2004, and then spread rapidly through the French territory but also to adjacent European countries (Spa.n, Portugal, and Belgium). During summer and autumn, V. velutina workers hunt domestic honeybees, Apis mellifera, for feeding their larvae. The impa.t of this alien species is mainly economic, beekeepers experiencing heavy colony losses, but also ecological, V. velutina hunting other pollinators. In their year-round life cycle, nest initiation by single queen during spring is the critical stage. In invaded areas, spring queen trapping using food baits has been promoted by apicultural unions in order to limit V. velutina population expa.sion. The goals of this work were 1) to evaluate the yield of this method, 2) to identify appropriate sites for trapping, 3) to identify potential optimal climatic windows of capture, and 4) to quantify the impa.t on local entomofauna. Our results showed that water proximity enhances trapping but not beehives proximity, and that trapping is inefficient if average week temperatures are below 10°C. Although the trapping effect on biodiversity should be studied more carefully, spring queen trapping is highly questionable unless specific attractants could be proposed.

Malignancy and mortality in a population-based cohort of pa.ients with coeliac disease or ‘gluten sensitivity’

引用

World Journal of Gastroenterology 2007年第1期13卷 146-151页

作者： la Anderson SA McMillan RGP Watson P Monaghan AT Gavin C Fox LJ Murray Queen's University Belfast Centre for Clinical and Population Sciences Belfast United Kingdom Royal Group of Hospitals Regional Immunology Service Belfast United Kingdom Royal Group of Hospitals Institute of Clinical Science Belfast United Kingdom. Queen's University Belfast Northern Ireland Cancer Registry Belfast United Kingdom

AIM: To determine the risk of malignancy and mortality in pa.ients with a positive endomysial or anti-gliadin an- tibody test in Northern Ireland. METHODS: A population-based retrospective cohort study design was used. laboratory test results used in the diagnosis of coeliac disease were obtained from the Regional Immunology laboratory, cancer statistics from the Northern Ireland Cancer Registry and mortal- ity statistics from the General Registrar Office, Northern Ireland. Age standardized incidence ratios of malignant neoplasms and standardized mortality ratios of all-cause and cause-specific mortality were calculated. RESULTS: A total of 13 338 people had an endomysial antibody and/or an anti-gliadin antibody test in Northern Ireland between 1993 and 1996. There were 490 pa. tients who tested positive for endomysial antibodies and they were assumed to have coeliac disease. There were 1133 pa.ients who tested positive for anti-gliadin anti- bodies and they were defined as gluten sensitive. Ma- lignant neoplasms were not significantly associated with coeliac disease; however, all-cause mortality was signifi- cantly increased following diagnosis. The standardized incidence and mortality ratios for non-Hodgkin’s lym- phoma were increased in coeliac disease pa.ients but did not reach statistical significance. Lung and breast cancer incidence were significantly lower and all-cause mortal-ity, mortality from malignant neoplasms, non-Hodgkin’s lymphoma and digestive system disorders were signifi- cantly higher in gluten sensitive pa.ients compa.ed to the Northern Ireland population. CONCLUSION: pa.ients with coeliac disease or gluten sensitivity had higher mortality rates than the Northern Ireland population. This association persists more than one year after diagnosis in pa.ients testing positive for anti-gliadin antibodies. Breast cancer is significantly re- duced in the cohort of pa.ients with gluten sensitivity.
