1The tumor-selective over-expression of the human Hsp 70 gene is attributed to the aberrant controls at both initiation and elongation levels of transcription显示文摘The tumor selective over-expression of the human Hsp70 gene has been well documented in human tumors,linked to the poor prognosis,being refractory to chemo-and radio-therapies as well as the advanced stage of tumorous lesions in particular.However,both the nature and details of aberrations in the control of the Hsp70 expression in tumor remain enigmatic.By comparing various upstream segments of the Hsp70 gene for each''s ability to drive the luciferase reporter genes in the context of the tumor cell lines varying in their p53 status and an immortal normal liver cell line,we demonstrated in a great detail the defects in the control mechanisms at the both initiation and elongation levels of transcription being instrumental to the tumor selective profile of its expression.Our data should not only offer new insights into our understanding of the tumor specific over-expression of the human Hsp70 gene,but also paved the way for the rational utilization of the tumor selective mechanism with the Hsp70 at the central stage fortargeting the therapeutic gene expression to human tumors.LING CAI, JING DE ZHU,The State-key Laboratory for Oncogenes and Related Genes, Shanghai Cancer Institute, LN 25/2200, Xie-tu Road, Shanghai 200032, China 2003Cell Research2003,13,2:13

4Biosorption of Cu^(2+) and Zn^(2+) by raw and autoclaved Rocella phycopsis显示文摘The behavior of Cu2+ and Zn2+ biosorption onto raw and modified Roccella phycopsis from aqueous solutions was studied. Modification process was applied by autoclavation at 121°C for 30 min. The effcts of pH, initial metal concentration and biosorbent dosage were investigated. The maximum Cu2+ biosorption was achieved at pH 5.0 and the maximum biosorption capacities of 31.5 and 37.8 mg/g were recorded for raw and modified biosorbent, respectively. In the case of Zn2+ biosorption, maximum biosorption capacities were obtained at pH 4.0 as 29.1 and 35.3 mg/g for raw and modified biosorbent, respectively. Biosorption of Zn2+ and Cu2+ on all form of R. phycopsis increased much quickly with increasing initial metal concentrations from 10 to 100 mg/L. After modification process, probable changes in the surface polarity of raw and modified R. phycopsis were investigated by contact angle measurements. As expected, R. phycopsis has a polar surface and shows a highest contact angle with water, while after autoclavation water contact angle of R. phycopsis was significantly decreased from 47.5° to 34.4°.Emine Yalcln Kltigin avusoglu Kadir Klnalloglu 2010Journal of Environmental Sciences2010,22,3:7
5吻合口漏增加结肠癌根治术后远处转移率及长期死亡率:一项丹麦全国队列研究显示文摘背景和目的结直肠癌为世界最常见恶性肿瘤之一。全球每年约有120万新发病例,60万人死于本病。手术切除是患者长期无病生存的关键手段,但术后并发症却可对手术结局产生重要影响。吻合口瘘(anastomotic leak,AL)是结直肠癌根治手术的严重并发症类型,直接增加术后短期死亡率。根据不同手术类型,AL发生率约在3%至12%之间。目前仅有为数不多结果却彼此矛盾的研究关注结肠癌术后吻合口瘘对于肿瘤结局及长期生存的影响。而对于直肠癌患者的研究结果则一致显示AL与局部复发率及长期死亡率增加相关,而不影响远处转移发生率。与之相反,尚未有研究证实结肠癌术后AL与局部复发或远处转移相关。已有研究证实,AL可降低结肠癌患者的无病生存期及总生存期。本项针对结肠癌的丹麦全国性研究主要终点为确定AL对结肠癌术后存活超过120天以上患者局部复发及远处转移率的影响;次要终点为确定AL对患者长远期死亡率的影响。此外,通过一项亚组分析,评价AL对III期结肠癌患者实施辅助化疗(AC)的影响。方法本研究为一项丹麦全国范围的队列研究,所有9333例患者均来自丹麦结直肠癌研究组数据库,并结合丹麦病理登记系统与国家患者登记系统的相关数据。通过多变量Cox回归分析对混杂因素进行校正。结果研究结果表明,患者AL发生率为6.4%,术后120天内死亡744例。其余的8589例患者中,局部复发861例(10.0%),但与AL无关(校正风险比HR=0.78;95%CI:0.55~1.12;P=0.184)。远处转移1281例(14.9%),且AL患者远处转移发生率更高(校正HR=1.42,95%CI:1.13~1.178;P=0.003)。AL也与患者长期死亡率呈正相关(校正HR=1.20,95%CI:1.01~1.44;P=0.042)。在2841例III期患者中,AL与施行辅助化疗的可能性降低(校正HR=0.58,95%CI:0.45~0.74;P<0.001)以及初始治疗延迟显著相关(校16天,95%CI:12~20天;P<0.001)。结论结肠癌术后吻合口瘘显著增加远处转移发生率及长期全因死亡率。该结果或在部分程度上与取消或延迟辅助化疗相关。Krarup PM Nordholm-Carstensen A orgensen LN 张信华 2014消化肿瘤杂志(电子版)2014,0,1:7

7The promoter analysis of the human C17orf25 gene, a novel chromosome 17pl3.3 gene显示文摘The human C17orf25 gene (Accession No. AF177342) is one of thirteen genes cloned from a region displaying a high score of loss of heterozygosity within chromosome 17p13.3 in human hepatocellular car-cinoma in China[l]. To unveil the underlying mechanisms for the transcription regulation of this gene and understand its implication to the hepatocellular carcinogenesis, we looked into the relevant aspects by both bioinformatic and experimental executions. We found: 1, The abundant expression of the C17orf25 gene was evident in all the cell lines and tissue samples tested, showing little hepatoma-selectivity; 2, Its tran-scription starts at a single site, locating at -60 from the translation initiation codon; 3, A 58 bp fragment containing the transcription start, extending from -112 to -55, represents the minimal promoter; 4, The consensus sequence within this fragment recognized by SP1 contributes predominantly to the activity of the minimal promoter; 5, The bioinformatic analysis suggests that the C17ort25 gene may encode a protein in the family of the glyoxalase. Our data has provided some deep insight into both function and regulation of the C17orf25 gene in the context of the normal liver and hepatocellular carcinoma.JIAN YING GUO, JIAN XU, DA QIN MAO, LI LI FU, JIAN REN GU, JING DE ZHUThe State-Key Laboratory of Oncogenes and Related Genes, Shanghai Cancer Institute, Ln 2200/25, Xie-Tu Road, Shanghai 200032, China 2002Cell Research2002,12,5:7

10Neural Respiratory Drive Measured Using Surface Electromyography of Diaphragm as a Physiological Biomarker to Predict Hospitalization of Acute Exacerbation of Chronic Obstructive Pulmonary Disease Patients显示文摘Background: Neural respiratory drive (NRD) using diaphragm electromyography through an invasive transesophageal multi?electrode catheter can be used as a feasible clinical physiological parameter in patients with chronic obstructive pulmonary disease (COPD) to provide useful information on the treatment response. However, it remains unknown whether the surface diaphragm electromyogram (EMGdi) could be used to identify the deterioration of clinical symptoms and to predict the necessity of hospitalization in acute exacerbation of COPD (AECOPD) patients. Methods: COPD patients visiting the outpatient department due to acute exacerbation were enrolled in this study. All patients who were subjected to EMGdi and classical parameters such as spirometry parameters, arterial blood gas analysis, COPD assessment test (CAT) score, and the modified early warning score (MEWS) in outpatient department, would be treated effectively in the outpatient or inpatient settings according to the Global Initiative for Chronic Obstructive Lung Disease guideline. When the acute exacerbation of the patients was managed, all the examination above would be repeated. Results: We compared the relationships of admission?to?discharge changes (Δ) in the normalized value of the EMGdi, including the change of the percentage of maximal EMGdi (ΔEMGdi%max) and the change of the ratio of minute ventilation to the percentage of maximal EMGdi (ΔVE/EMGdi%max) with the changes of classical parameters. There was a significant positive association between ΔEMGdi%max and ΔCAT,ΔPaCO2, and ΔpH. The change (Δ) of EMGdi%max was negatively correlated with ΔPaO2/FiO2 in the course of the treatment of AECOPD. Compared with the classical parameters including forced expiratory volume in 1 s, MEWS, PaO2/FiO2, the EMGdi%max (odds ratio 1.143, 95% confidence interval 1.004–1.300) has a higher sensitivity when detecting the early exacerbation and enables to predict the admission of hospital in the whole cohort. Conclusions: The changes of surface EMGdi parameters had a direct correlation with classical measures in the whole cohort of AECOPD. The measurement of NRD by surface EMGdi represents a practical physiological biomarker, which may be helpful in detecting patients who should be hospitalized timely.Dan-Dan Zhang Gan Ln Xaan-Feng Zhu Ling-Ling Zhang Jia Gao Li-Cheng Shi Jian-Hua Gu Jian-Nan Liu 2018Chinese Medical Journal2018,,23:5
11结肠癌术后吻合口瘘与患者不良结局有关显示文摘结肠癌术后吻合口瘘是否可增加病情复发风险,目前尚无翔实证据。哥本哈根大学Peter-Martin Krarup博士等人进行了一项研究,该研究对象为经结肠癌根治性切除手术治疗后存活120天的结肠癌患者,目的为考查结肠癌术后吻合口瘘对患者病情复发与长期死亡的影响。这项研究结果发表于2013年9月16日在线出版的《外科学年鉴》( Annals of Surgery )杂志上。 这是一项对登记于丹麦结直肠癌研究组数据库中的9333例患者进行的前瞻性研究。研究结果表明,患者结肠癌术后吻合口瘘发生率为6.4%,有744例患者于120天内死亡。在其余的8589例患者中,有861例(10.0%)出现局部复发,但与结肠癌术后吻合口瘘无关。1281例(14.9%)患者出现远端复发,远端复发常发生于结肠癌术后吻合口瘘后。结肠癌术后吻合口瘘也与患者远期死亡率有关。在2841例III期患者中,结肠癌术后吻合口瘘与辅助化疗可能性增加和初始治疗延迟有关。Krarup PM Nordholm-Carstensen A Jorgensen LN 2013中华结直肠疾病电子杂志2013,2,4:4
12Interleukin-10 gene polymorphisms and hepatocellular carcinoma susceptibility:A meta-analysis显示文摘AIM: To assess the association between Interleu-kin-10 (IL-10) gene IL-10-1082 (G/A), IL-10-592(C/A), IL-10-819 (T/C) polymorphisms and hepatocellular carcinoma (HCC) susceptibility.METHODS: Two investigators independently searched the Medline, Embase, China National Knowledge Infrastructure, and Chinese Biomedicine Database. Summary odds ratios (ORs) and 95% conf idence intervals (95% CIs) for IL-10 polymorphisms and HCC were cal-culated in a fixed-effects model (the Mantel-Haenszel method) and a random-effects model (the DerSimonian and Laird method) when appropriate. RESULTS: This meta analysis included seven eligiblestudies, which included 1012 HCC cases and 2308 controls. Overall, IL-10-1082 G/A polymorphism was not associated with the risk of HCC (AA vs AG + GG, OR = 1.11, 95% CI = 0.90-1.37). When stratifying for ethnicity, the results were similar (Asian, OR = 1.12, 95% CI = 0.87-1.44; non-Asian, OR = 1.10, 95% CI = 0.75-1.60). In the overall analysis, the IL-10 polymorphism at position -592 (C/A) was identified as a genetic risk factor for HCC among Asians; patients carrying the IL-10-592*C allele had an increased risk of HCC (OR = 1.29, 95% CI = 1.12-1.49). No association was observed between the IL-10-819 T/C polymorphism and HCC susceptibility (TT vs TC + CC, OR = 1.02, 95% CI = 0.79-1.32).CONCLUSION: This meta-analysis suggests that IL-10-592 A/C polymorphism may be associated with HCC among Asians. IL-10-1082 G/A and IL-10-819 T/C polymorphisms were not detected to be related to the risk for HCC.Yong-Gang Wei, Fei Liu, Bo Li, Xi Chen, Yu Ma, Lv-Nan Yan, Tian-Fu Wen, Ming-Qing Xu, Wen-Tao Wang, Jia-Yin YangYong-Gang Wei, Fei Liu, Bo Li, Xi Chen, Yu Ma, Lv-Nan Yan, Tian-Fu Wen, Ming-Qing Xu, Wen-Tao Wang, Jia-Yin Yang, Department of Liver and Vascular Surgery, West China Hospital, Sichuan University, Chengdu 610041, Sichuan Prov- ince, China Author contributions: Wei YG and Liu F designed the study, collected and analyzed the data and wrote the manuscript Li B collected and analyzed the data and wrote the manuscript Chen X and Ma Y collected and analyzed the data Yan LN analyzed the data and contributed to the discussion Wen TF and Xu MQ revised the manuscript Wang WT and Yang JY contributed to the discussion Wei YG and Liu F contributed equally to this work. 2011World Journal of Gastroenterology2011,17,34:3
