1Cloning and expression of MXR7 gene in human HCC tissue显示文摘AIM To clone and identify the whole cDNA ofMXR7 gene and to find out its expression inhuman HCC,and normal tissues.METHODS The DNA primers were designed andsynthesized according to the whole cDNAsequence of MXR? gene.The cDNA of humanHCC was taken as the template while the cDNA ofMXR7 gene was synthesized by polymerasechain reaction(PCR).Recombinant DNAconforming to reading frame was constructed byconnecting purified PCR product of the cDNA ofMXR? gene with expression vector pGEX-5X-1 offusion protein.The plasmid MXRT/pGEX-5X-1was identified by sequencing.Using 32p labeledMXR? cDNA as probe,MXR7 mRNA expressionwas detected by Northern blot analysis in 12different human normal tissues,7 preoperativelyuntreated non-liver tumor tissues,30preoperatively untreated HCC,theparacancerous liver tissues and 12 normal livertissues samples.RESULTS Restriction enzyme and sequenceanalysis confirmed that the insertion sequence invector pGEX-5X-1 was the same as the cDNAsequence of MXR7 gene.Northern blot analysisshowed no expression of MXR? mRNA in 12 kindsof normal human tissues including liver,7 tumortissues in other sites and 12 normal livertissues,the frequencies of MXR7 mRNA expression in HCC and paracancerous livertissues were 76.6% and 13.3%,respectively.The frequency of MXR7 mRNA expression in HCCwithout elevation of serum AFP and in HCC<5cm was 90%(9/10)and 83.3%(5/6),respectively.CONCLUSION MXR7 mRNA is highly expressedin human HCC,which is specific and occurs at anearly stage of HCC,suggesting MXR7 mRNA canbe a tumor biomarker for HCC.The detection ofMXR7 mRNA expression in the biopsied livertissue is helpful in discovering early subclinicalliver cancer in those with negative serum AFP.Zhou XP Wang HY Yang GS Chen ZJ Li BA Wu MC 2000World Journal of Gastroenterology2000,6,1:23

4Microstructure of Al-Si Alloys Rapidly Solidified from the Different Temperature Melts显示文摘Hypo- and hyper-eutectic Al-Si alloys were rapidly solidified from the low or high temperature melt using water quenching and melt-spinning technique. The differences in microstructure of rapid solidification alloys were studied by scanning and transmission electron microscopy,and X-ray diffraction methods. The primary silicon in the Al-22(wt pct)Si alloy quenched in room temperature water from high temperature melt was smaller than that quenched from low temperature melt. Compared with the ribbons spun from low temperature melt, the ribbons spun from high temperature melt had finer Al-rich and Si-rich phase particles in either Al-7(wt pct)Si or Al-18(Wt pct)Si alloy. The mechanism was explained by the nature of the liquidGui, MC Jia, J Song, GS Li, QC 1999Journal of Materials Science & Technology1999,15,3:7

6儿童期肥胖、成年期肥胖和心血管风险因子显示文摘过去30年,儿童超重或肥胖的发生率明显增加[1]。儿童期肥胖是死亡率增加的预测因子,这主要是由于儿童期肥胖可导致心血管疾病发生率增加。相关的预测研究提示"肥胖流行症"可能改变目前心血管疾病死亡率下降的趋势,使现今儿童的寿命缩短。Juonala M Magnussen CG Berenson GS Venn A Burns TL Sabin MA Srinivasan SR Daniels SR Davis PH Chen W Sun C Cheung M Viikari JS Dwyer T Raitakari OT 叶鹏 2012中华高血压杂志2012,20,1:6
7Recognition Interactions of Metal-complexing Imprinted Polymer显示文摘Molecularly imprinted polymer, exhibiting considerable enantioselectivity for L-mandelic acid, was prepared using metal coordination-chelation interaction. By evaluating the recognition characteristics in the chromatographic mode, the recognition interactions were proposed: specific and nonspecific metal coordination-chelation interaction and hydrophobic interaction were responsible for substrate binding on metal-complexing imprinted polymer; while the selective recognition only came from specific metal coordination-chelation interaction and specific hydrophobic interaction.Liu, Y Ding, GS De Wang, J 2005Chinese Chemical Letters2005,16,6:5
8石杉碱甲对重度抑郁症患者认知功能障碍的治疗:一项随机对照试验的系统综述(英文)显示文摘背景:乙酰胆碱酯酶(Acetylcholinesterase,AChE)抑制剂在重性抑郁障碍(Major Depressive Disorder,MDD)的动物模型和人类患者中已被证实可以有效地治疗认知障碍。石杉碱甲(Huperzine A,HupA)是一种来自于被称为蛇足石杉(Huperzineserrata)的石松属传统中医药,是一种强有力的AChE抑制剂,已被用于抑郁症的辅助治疗,但有尚无关石杉碱甲对MDD的强化治疗作用的meta分析。目标:对有关石杉碱甲强化治疗抑郁症的随机对照试验进行系统综述和meta分析,评估其疗效及安全性。方法:两位评估者独立检索9个英文和中文数据库,选择符合预先确定的纳入标准的相关研究,提取有关疗效和安全性的数据,并进行质量评估和数据拟合合成。结果:纳入了三项中国低质量的随机对照试验(总共n=238),这些试验比较了单用抗抑郁药治疗抑郁症与抗抑郁药和石杉碱甲的联合治疗,试验中的被试从16岁到60岁。研究中石杉碱甲辅助抗抑郁药治疗的平均时间仅为6.7周。这三项研究都是公开标签未使用盲法,所以他们的总体质量评定为差。总体样本的Meta分析发现两组抑郁症状的改善没有显著性差异(差异加权差为-1.90,95%CI可信区间为-4.23至0.44,p=0.11)。然而,石杉碱甲辅助治疗组比单用抗抑郁药治疗组在认知功能和生活质量方面有显著改善(如威斯康星卡片分类测验、韦氏记忆量表修订的评估)。组间药物不良反应的发生率无显著性差异。结论:有关在接受抗抑郁药的MDD患者使用HupA辅助治疗的疗效和安全性的可获取数据不足,难以得出有关其疗效和安全性的明确结论。汇集国内3项低质量的RCT数据没有发现采用辅助使用HupA治疗抑郁症状的优势,但辅助使用HupA与更快改善经常伴随MDD出现的认知症状相关。郑伟 向应强 Ungvari GS Chiu F.K.H Ng H.C 王颖 项玉涛 2016上海精神医学2016,28,2:4

19Association of gene and protein expression and genetic polymorphism of CC chemokine ligand 4 in colorectal cancer显示文摘BACKGROUND Leukocytes,such as T cells and macrophages,play an important role in tumorigenesis.CC chemokine ligand(CCL)4,which is produced by lymphocytes and macrophages,has been found to be expressed in the mucosa of the gastrointestinal tract and is a potent chemoattractant for various leukocytes.AIM To examine CCL4 expression and its genetic polymorphism rs10491121 in patients with colorectal cancer(CRC)and evaluate their prognostic significance.METHODS Luminex technology was used to determine CCL4 Levels in CRC tissue(n=98),compared with paired normal tissue,and in plasma from patients with CRC(n=103),compared with healthy controls(n=97).Included patients had undergone surgical resection for primary colorectal adenocarcinomas between 1996 and 2019 at the Department of Surgery,Ryhov County Hospital,Jönköping,Sweden.Reverse transcription quantitative PCR was used to investigate the CCL4 gene expression in CRC tissue(n=101).Paired normal tissue and TaqMan single nucleotide polymorphism assays were used for the CCL4 rs10491121 polymorphism in 610 CRC patients and 409 healthy controls.RESULTS The CCL4 protein and messenger RNA expression levels were higher in CRC tissue than in normal paired tissue(90%,P<0.001 and 45%,P<0.05,respectively).CRC tissue from patients with localized disease had 2.8-fold higher protein expression levels than that from patients with disseminated disease.Low CCL4 protein expression levels in CRC tissue were associated with a 30%lower cancer-specific survival rate in patients(P<0.01).The level of plasma CCL4 was 11%higher in CRC patients than in healthy controls(P<0.05)and was positively correlated(r=0.56,P<0.01)with the CCL4 protein level in CRC tissue.The analysis of CCL4 gene polymorphism rs10491121 showed a difference(P<0.05)between localized disease and disseminated disease in the right colon,with a dominance of allele A in localized disease.Moreover,the rate of the A allele was higher among CRC patients with mucinous cancer than among those with nonmucinous cancer.CONCLUSION The present study indicates that the CRC tissue levels of CCL4 and CCL4 gene polymorphism rs10491121,particularly in the right colon,are associated with clinical outcome in CRC patients.Levar Shamoun Kalle Landerholm Amanda Balboa Ramilo Roland E Andersson Jan Dimberg Dick Wågsäter 2021World Journal of Gastroenterology2021,27,30:2
20符合HDMI 1.4a接口标准的3D电视测试信号显示文摘在影院中大放异彩的3D技术目前已可以在家庭中实现。最新的HDMI 1.4a标准为在消费电子产品中传输3D视频提供了依据。新的或更多先进的显示技术遵循该标准,就可以将视频数据转换为三维效果显示出来。然而,这些新技术也给3D电视制造商带来了新挑战。尤其在开发和质量认证环节。Harald Gsdl 吴敏 2011电视技术2011,35,4:2
