1Porous LiFePO_(4)/NiP Composite Nanospheres as the Cathode Materials in Rechargeable Lithium Ion Batteries显示文摘We report the synthesis of porous LiFePO4/NiP composite nanospheres and their application in rechargeable lithium-ion batteries.A simple one-step spraying technique was developed to prepare LiFePO_(4)/NiP composite nanospheres with an electrical conductivity 10^(3)-10^(4) times that of bulk particles of LiFePO_(4).Electrochemical measurements show that LiFePO_(4) nanospheres with a uniform loading of 0.86 wt%1.50 wt%NiP exhibit high discharge capacity,good cycling reversibility,and low apparent activation energies.The superior electrode performance of the as-prepared composite nanospheres results from the greatly enhanced electrical conductivity and porous structure of the materials.Chunsheng Li Shaoyan Zhang Fangyi Cheng Weiqiang Ji Jun Chen 2008Nano Research2008,1,3:12
2CD30 expression in extranodal natural killer/T-cell lymphoma,nasal type among 622 cases of mature T-cell and natural killer-cell lymphoma at a single institution in South China显示文摘Background:Mature T-cell and natural killer(NK)-cell lymphomas compose a heterogeneous group of non-Hodgkin lymphomas,and extranodal NK/T-cell lymphoma,nasal type(ENKTL) is an aggressive subtype with sporadic CD30 expression.However,the significance of CD30 expression in ENKTL is controversial.We aimed to classify a large cohort of patients with mature T-cell and NK-cell lymphomas according to the 2016 World Health Organization(WHO) classification guidelines and to study the association between CD30 expression and prognosis of patients with ENKTL.Methods:We selected consecutive patients with mature T-cell and NK-cell lymphomas who attended our institution between September 1,2009 and August 31,2013.We classified the lymphomas according to the 2016 revision of the WHO classification of lymphoid neoplasms,analyzed the associations between CD30 expression and clinicopathologic features of ENKTL patients,and evaluated the prognostic implications of CD30 expression.Results:We identified 622 consecutive patients with mature T-cell and NK-cell lymphomas,including 317(51.0%)patients with ENKTL.In addition,CD30 expression was detected in 43(47.3%) of a subset of 91 patients with ENKTL.No clinicopathologic features were associated with CD30 expression,and CD30 positivity showed no prognostic significance in patients with ENKTL.Conclusions:ENKTL is the most common type of mature T-cell and NK-cell lymphoma diagnosed at our institution.CD30 is frequently expressed in ENKTL and represents a therapeutic target;however,it may not be a prognostic marker.Yanfen Feng Huilan Rao Yiyan Lei Yuhua Huang Fang Wang Yu Zhang Shaoyan Xi Qiuliang Wu Jianyong Shao 2017Chinese Journal of Cancer2017,36,6:10
3Mining,characterization,and exploitation of EST-derived microsatellites in Gossypium barbadense显示文摘Simple sequence repeats(SSRs) have been widely applied as molecular markers in genetic studies.However,the number of expressed sequence tags(ESTs) and SSR markers from Gossypium barbadense is fewer than those from other cotton species.In this study,EST-SSR distribution from G.barbadense was characterized and new G.barbadense-derived EST-SSR markers were determined on the basis of the ESTs obtained by randomly sequencing 2 cDNA libraries associated with fiber development in G.barbadense.By mining 9697 non-redundant ESTs,a total of 638 SSR loci derived from 595 ESTs were observed.In G.barbadense,the frequency of ESTs containing SSRs was 6.13%,with an average of 1 SSR in every 10.4 kb of EST sequence.Furthermore,trinucleotide was found to be the most abundant repeat type among 2-6-nucleotide repeat types.It accounted for 26.6% of the total,followed by the hexanucleotide(26.0%) and pentanucleotide repeats(25.9%).Among all the repeat motifs,(AAG)n accounted for the highest proportion.EST-SSR primer pairs were developed using the Primer3 program,and the redundant primers were removed using the virtual PCR approach.As a result,380 non-redundant EST-SSR primer pairs were developed and used to detect polymorphisms between the mapping parents G.hirsutum 'TM-1' and G.barbadense 'Hai7124' for constructing linkage groups in cultivated allotetraploid cotton.Out of these,98(25.8%) primer pairs detected polymorphisms.Finally,95 polymorphic loci from 82 primer pairs were integrated into the backbone genetic map;of these,42 were mapped into the A subgenome and 53 into the D subgenome.The present work provided the foundation for constructing saturated genetic maps and conducting comparative genomic studies on different cotton species.LU YuanDa CAI CaiPing WANG Lei LIN ShaoYan ZHAO Liang TIAN LiangLiang LU JunHong ZHANG TianZhen GUO WangZhen 2010Chinese Science Bulletin2010,55,18:5
4Deformation of the Haiyuan-Liupanshan fault zone inferred from the denser GPS observations显示文摘The Haiyuan-Liupanshan fault,an active tectonic feature at the Tibetan Plateau's northeastern boundary,was ruptured by two MS earthquakes(1920 and 1927)bracketing an unbroken section(the Tianzhu seismic gap).A high seismic hazard is expected along the gap.To monitor deformation characteristics and do a seismic risk assessment,we made measurements at two newly built campaign-mode Global Positioning System(GPS) stations and 13 pre-existing stations in 2013 and 2014.Adding existing data from 1999 to 2014,we derived a new velocity field.Based on the horizontal velocity,we used three block models to invert the deformation of four crustal blocks.The results suggest non-uniform deformation in the interior of the Lanzhou block,the Ordos block and the Alaxan block,but uniform deformation in the Qilian block.Fault slip rates derived from block models show a decreasing trend from west to east,(2.0-3.2 mm/a on the Haiyuan fault to 0.9-1.5 mm/a on the Liupanshan fault).The Haiyuan fault evidences sinistral striking-slip movement,while the Liupanshan fault is primarily thrusting due to transformation of the displacement between the strike-slip and crustal shortening.The locking depth of each segment along the Haiyuan fault obtained by fitting the fault parallel velocities varies drastically from west to east(21.8-7.1 km).The moment accumulation rate,calculated using the slip rate and locking depth,is positively correlated with the locking depth.Given the paucity of large seismic events during the previous millennium,the Tuolaishan segment and the Maomaoshan segment have higher likelihood of nucleation for a future event.Yanchuan Li Chunyan Qu Xinjian Shan Xiaogang Song Guohong Zhang Weijun Gan Shaoyan Wen Zhenjie Wang 2015Earthquake Science2015,28,5:4
5Fungal diversity in major oil-shale mines in China显示文摘As an insufficiently utilized energy resource,oil shale is conducive to the formation of characteristic microbial communities due to its special geological origins.However,little is known about fungal diversity in oil shale.Polymerase chain reaction cloning was used to construct the fungal ribosomal deoxyribonucleic acid internal transcribed spacer(r DNA ITS)clone libraries of Huadian Mine in Jilin Province,Maoming Mine in Guangdong Province,and Fushun Mine in Liaoning Province.Pure culture and molecular identification were applied for the isolation of cultivable fungi in fresh oil shale of each mine.Results of clone libraries indicated that each mine had over 50% Ascomycota(58.4%–98.9%)and 1.1%–13.5%unidentified fungi.Fushun Mine and Huadian Mine had 5.9% and 28.1% Basidiomycota,respectively.Huadian Mine showed the highest fungal diversity,followed by Fushun Mine and Maoming Mine.Jaccard indexes showed that the similarities between any two of three fungal communities at the genus level were very low,indicating that fungi in each mine developed independently during the long geological adaptation and formed a community composition fitting the environment.In the fresh oil-shale samples of the three mines,cultivable fungal phyla were consistent with the results of clone libraries.Fifteen genera and several unidentified fungi were identified as Ascomycota and Basidiomycota using pure culture.Penicillium was the only genus found in all three mines.These findings contributed to gaining a clear understanding of current fungal resources in major oil-shale mines in China and provided useful information for relevant studies on isolation of indigenous fungi carrying functional genes from oil shale.Shaoyan Jiang Wenxing Wang Xiangxin Xue Chengyou Cao Ying Zhang 2016Journal of Environmental Sciences2016,28,3:4
6Ecological principle meets cancer treatment: treating children with acute myeloid leukemia with low-dose chemotherapy显示文摘Standard chemotherapy regimens for remission induction of pediatric acute myeloid leukemia(AML) are associated with significant morbidity and mortality. We performed a cohort study to determine the impact of reducing the intensity of remission induction chemotherapy on the outcomes of selected children with AML treated with a low-dose induction regimen plus granulocyte colony stimulating factor(G-CSF)(low-dose chemotherapy(LDC)/G-CSF). Complete response(CR) after two induction courses was attained in 87.0%(40/46) of patients receiving LDC/G-CSF. Post-remission therapy was offered to all patients, and included standard consolidation and/or stem cell transplantation. During the study period, an additional 94 consecutive children with AML treated with standard chemotherapy(SDC) for induction(80/94(85.1%) of the patients attained CR after induction Ⅱ, P = 0.953) and post-remission. In this non-randomized study, there were no significant differences in 4-year event-free(67.4 vs. 70.7%;P = 0.99)and overall(70.3 vs. 74.6%, P = 0.69) survival in the LDC/G-CSF and SDC cohorts, respectively. After the first course of induction, recovery of white blood cell(WBC) and platelet counts were significantly faster in patients receiving LDC/G-CSF than in those receiving SDC(11.5 vs. 18.5 d for WBCs(P < 0.001);15.5 vs. 22.0 d for platelets(P < 0.001)). To examine the quality of molecular response, targeted deep sequencing was performed. Of 137 mutations detected at diagnosis in 20 children who attained hematological CR after two courses of LDC/G-CSF(n = 9) or SDC(n = 11), all of the mutations were below the reference value(variant allelic frequency <2.5%) after two courses, irrespective of the treatment group. In conclusion, children with AML receiving LDC/G-CSF appear to have similar outcomes and mutation clearance levels, but significantly lower toxicity than those receiving SDC. Thus, LDC/G-CSF should be further evaluated as an effective alternative to remission induction in pediatric AML.Yixin Hu Aili Chen Xinchang Zheng Jun Lu Hailong He Jin Yang Ya Zhang Pinpin Sui Jingyi Yang Fuhong He Yi Wang Peifang Xiao Xin Liu Yinmei Zhou Deqing Pei Cheng Cheng Raul C.

7Polymorphisms of MTHFR and TYMS predict capecitabine-induced hand-foot syndrome in patients with metastatic breast cancer显示文摘Background:Breast cancer is a global problem,and a large number of new cases are diagnosed every year.Capecit-abine is effective in patients with metastatic breast cancer(MBC).Hand-foot syndrome(HFS)is a common adverse effect of capecitabine.In this study,we investigated the association between single nucleotide polymorphisms(SNPs)in genes involved in capecitabine metabolism pathways and capecitabine-induced HFS in Chinese patients with MBC to identify some predictive genetic biomarkers.Methods:We selected 3 genes involved in capecitabine metabolism and screened genetic variants in these target genes.We genotyped a total of 22 SNPs in the thymidylate synthase gene(TYMS),the methylene tetrahydrofolate reductase gene(MTHFR),and the ribonucleotide reductase M1 gene(RRM1)in 342 MBC patients treated with capecit-abine-based chemotherapy.The genotype distributions of each SNP in patients with and without HFS were assessed using Pearson’sχ^(2)test,and the relationship between HFS and genotypes of SNPs was determined using logistic regression analysis.The association between SNPs and their corresponding gene expression was analyzed using the Blood expression quantitative trait loci(eQTL)browser online tools.Results:We found 4 positive sites for HFS in the TYMS and MTHFR genes:TYMS rs2606241(P=0.022),TYMS rs2853741(P=0.019),MTHFR rs3737964(P=0.029),and MTHFR rs4846048(P=0.030).Logistic regression analyses showed that the genotype AG of MTHFR rs3737964[odds ratio(OR)=0.54,95%confidence interval(CI)0.31-0.97,P=0.038]and MTHFR rs4846048(OR=0.54,95%CI 0.30-0.98,P=0.042)were protective factors of HFS,whereas the genotype CT of TYMS rs2853741(OR=2.25,95%CI 1.31-3.87,P=0.012)increased the risk of HFS.The association between the genotype GT of TYMS rs2606241(OR=1.27,95%CI 0.73-2.23,P=0.012)and HFS was uncertain.Further eQTL analyses confirmed that the alleles of rs3737964 and rs4846048 affected the gene expression levels of MTHFR in cis.Conclusions:We have identified four potentially useful pharmacogenetic markers,TYMS rs2606241,TYMS rs2853741,MTHFR rs3737964,and MTHFR rs4846048 to predict capecitabine-induced HFS in MBC patients.Shaoyan Lin Jian Yue Xiuwen Guan Peng Yuan Jiayu Wang Yang Luo Ying Fan Ruigang Cai Qiao Li Shanshan Chen Pin Zhang Qing Li Fei Ma Binghe Xu 2019Cancer Communications2019,39,1:3

9Comments on National guidelines for diagnosis and treatment of thyroid cancer 2022 in China (English version)显示文摘Thyroid cancer (TC) is the most common endocrine system cancer, of note, the overall survival of TC in China is suboptimal when comparing with the developed countries such as US (84.3%vs.98.3%), posing a great challenge among professionals involved in this field.Standardization of its diagnosis and treatment not only provides the basis for all the care givers to promote the entire level of TC management, but also is helpful in shortening the distance between China and other developed countries. A multidisciplinary team (MDT)should be involved in the comprehensive clinical management of TC, particularly for those advanced or refractory TC, which needs cooperation among members from ultrasonography, radiology, pathology, surgery.Hao Wang Jian Wang Xiang Wang Yiming Zhu Yuqing Sun Xin Zhang Xiaorong Hou Kun Zheng Shaoyan Liu Yansong Lin 2022Chinese Journal of Cancer Research2022,34,5:2
10PITPNC1 promotes the thermogenesis of brown adipose tissue under acute cold exposure显示文摘Brown adipose tissue (BAT) plays an essential role in non-shivering thermogenesis. The phosphatidylinositol transfer protein, cytoplasmic 1 (PITPNC1) is identified as a lipid transporter that reciprocally transfers phospholipids between intracellular membrane structures. However, the physiological significance of PITPNC1 and its regulatory mechanism remain unclear. Here, we demonstrate that PITPNC1 is a key player in thermogenesis of BAT. While Pitpnc1^(−/−) mice do not differ with wildtype mice in body weight and insulin sensitivity on either chow or high-fat diet, they develop hypothermia when subjected to acute cold exposure at 4℃. The Pitpnc1^(−/−) brown adipocytes exhibit defective β-oxidation and abnormal thermogenesis-related metabolism pathways in mitochondria. The deficiency of lipid mobilization in Pitpnc1^(−/−) brown adipocytes might be the result of excessive accumulation of phosphatidylcholine and a reduction of phosphatidic acid. Our findings have uncovered significant roles of PITPNC1 in mitochondrial phospholipid homeostasis and BAT thermogenesis.Guoqing Tang Chengxin Ma Liangkui Li Shaoyan Zhang Fengsheng Li Jin Wu Yesheng Yin Qing Zhu Yan Liang Ru Wang He Huang Tong-Jin Zhao Hongyuan Yang Peng Li Feng-Jung Chen 2022Science China(Life Sciences)2022,65,11:2

17MTHFR和TYMS的多态性预测转移性乳腺癌患者因卡培他滨诱发的手足综合征显示文摘背景与目的乳腺癌是一个全球性问题,每年都会诊断出大量的新发病例。卡培他滨对转移性乳腺癌(metastatic breast cancer,MBC)患者有效。手足综合征(hand-foot syndrome,HFS)是卡培他滨的常见不良反应。在本文中,我们研究了卡培他滨代谢通路相关基因中的单核苷酸多态性(single nucleotide polymorphisms,SNPs)与卡培他滨诱导的中国MBC患者HFS之间的相关性,以确定一些具有预测性的生物标志物基因。方法我们选择了3个参与卡培他滨代谢的基因,并筛选了这些靶基因的遗传变体。我们对342例接受卡培他滨化疗的MBC患者的胸苷酸合酶基因(thymidylate synthase gene,TYMS)、亚甲基四氢叶酸还原酶基因(methylene tetrahydrofolate reductase gene,MTHFR)和核糖核苷酸还原酶M1基因(ribonucleotide reductaseM1gene,RRM1)中的22个SNPs进行了基因分型。使用Pearson’sχ2检验评估患有和不患有HFS的患者中每个SNP的基因型分布,并使用logistic回归分析确定HFS与SNP的基因型之间的相关性。使用血液表达数量定量性状基因座(expression quantitative trait loci,e QTL)Browser在线工具分析了SNP及其对应基因表达之间的相关性。结果我们在TYMS和MTHFR基因中发现了4个HFS阳性位点:TYMS rs2606241(P=0.022)、TYMS rs2853741(P=0.019)、MTHFR rs3737964(P=0.029)和MTHFR rs4846048(P=0.030)。Logistic回归分析显示,MTHFR rs3737964[比值比(odds ratio,OR)=0.54,95%置信区间(confidence interval,CI):0.3–0.97,P=0.038]和MTHFRrs4846048(OR=0.54,95%CI:0.30–0.98,P=0.042)的基因型AG是HFS的保护因素,而TYMS rs2853741的基因型CT(OR=2.25,95%CI:1.31–3.87,P=0.012)增加了HFS的风险。TYMSrs2606241的基因型GT(OR=1.27,95%CI:0.73–2.23,P=0.012)与HFS之间的相关性尚不确定。进一步的e QTL分析证实,rs3737964和rs4846048的等位基因影响顺式MTHFR的基因表达水平。结论我们已经确定了4个潜在有效的药物遗传学标记,TYMS rs2606241、TYMS rs2853741、MTHFR rs3737964和MTHFR rs4846048可以预测卡培他滨诱导的MBC患者的HFS。Shaoyan Lin Jian Yue Xiuwen Guan Peng Yuan Jiayu Wang Yang Luo Ying Fan Ruigang Cai Qiao Li Shanshan Chen Pin Zhang Qing Li Fei Ma Binghe Xu 2019癌症2019,38,11:1
