1Reassessment of functional dyspepsia:From the editor显示文摘Functional dyspepsia (FD) is a heterogeneous disorder of yet unsure etiology. Commonly encountered, it poses a substantial social and economic burden. It can be classified into different subgroups based on the most predominant symptom. Early studies seem to suggest that such sub-classifications correlate to different etiological factors. However, the most important pathogenetic factor appears to be that of visceral hypersensititivity; the stomach seems toAndrew Seng Boon Chua MD 2006World Journal of Gastroenterology2006,12,17:53
2Is nasopharyngeal cancer really a “Cantonese cancer”?显示文摘Nasopharyngeal cancer(NPC) is endemic in Southern China,with Guandong province and Hong Kong reporting some of the highest incidences in the world.The journal Science has called it a 'Cantonese cancer'.We propose that in fact NPC is a cancer that originated in the Bai-Yue('proto-Tai-Kadai' or 'proto-Austronesian' or 'proto-Zhuang') peoples and was transmitted to the Han Chinese in southern China through intermarriage.However,the work by John Ho raised the profile of NPC,and because of the high incidence of NPC in Hong Kong and Guangzhou,NPC became known as a Cantonese cancer.We searched historical articles,articles cited in PubMed,Google,monographs,books and Internet articles relating to genetics of the peoples with high populations of NPC.The migration history of these various peoples was extensively researched,and where possible,their genetic fingerprint identified to corroborate with historical accounts.Genetic and anthropological evidence suggest there are a lot of similarities between the Bai-Yue and the aboriginal peoples of Borneo and Northeast India;between Inuit of Greenland,Austronesian Mayalo-Polynesians of Southeast Asia and Polynesians of Oceania,suggesting some common ancestry.Genetic studies also suggest the present Cantonese,Minnans and Hakkas are probably an admixture of northern Han and southern Bai-Yue.All these populations have a high incidence of NPC.Very early contact between southern Chinese and peoples of East Africa and Arabia can also account for the intermediate incidence of NPC in these regions.Joseph Tien Seng Wee Tam Cam Ha Susan Li Er Loong Chao-Nan Qian 2010Chinese Journal of Cancer2010,29,5:37
3新加坡最大回用水处理厂污水短程硝化厌氧氨氧化脱氮工艺显示文摘总结了新加坡樟宜回用水处理厂4次采样的结果,该厂日处理城市污水80万t.在好氧区很好地实现了部分硝化和亚硝酸盐积累,其中好氧氨氧化率平均为72.2%,亚硝酸盐积累率平均为76.0%.在缺氧区氨氮和亚硝酸盐得到了同步去除(厌氧氨氧化).物料衡算结果表明:初沉池的出水总氮的37.5%是通过自养脱氮去除,27.1%是通过传统的硝化/反硝化脱氮去除,其余部分总氮则存在于活性污泥和出水中.微生物和动力学研究表明:短悬浮或游离的厌氧氨氧化菌可存在于污泥龄较短的污水处理系统.最后从出水氮质量浓度、pH、碱度、曝气能耗及反应器容积等方面,将樟宜回用水处理厂的分段进水活性污泥法工艺与新加坡其他3个回用水处理厂的MEL/LE工艺进行了对比分析.Cao Yeshi Kwok Bee Hong Yan Zhou Yu Liu He Jianzhong Chua Seng Chye Wah Yuen Long Yahya Ghani 2015北京工业大学学报2015,41,10:32

7Clostridium difficile causing acute renal failure: Case presentation and review显示文摘AIM: Clostridium difficile infection is primarily a nosocomial infection but asymptomatic carriers of Clostridium difficile can be found in up to 5% of the general population.Ampicillin, cephalosporins and clindamycin are the antibiotics that are most frequently associated with Clostridium difficile-associated diarrhea or colitis. Little is known about acute renal failure as a consequence of Clostridium difficile-associated diarrhea.METHODS: In this case report, we describe the course of Clostridium difficile-associated diarrhea in an 82-yearold patient developing acute renal failure. Stopping the offending agent and symptomatic therapy brought a rapid improvement of diarrhea and acute renal failure, full recovery was gained 18 d after admission. In a systematic review we looked for links between the two conditions.RESULTS: The link between Clostridium difficilr-associated diarrhea and acute renal failure in our patient was most likely volume depletion. However, in experimental studies a direct influence of Clostridium difficile toxins on renal duct cells could be shown.CONCLUSION: Rapid diagnosis, nonspecific supportive treatment and specific antibiotic treatment, especially in the elderly, may lower excess mortality Clostridium difficile-associated diarrhea and renal failure being possible complications.Jasmin Arrich Gottfried H.Sodeck Gürkan Seng(o|¨)lge Christoforos Konnaris Marcus Müllner Anton N.Laggner Hans Domanovits 2005World Journal of Gastroenterology2005,11,8:15
8Effects of oxidized low density lipoprotein on the growth of human artery smooth muscle cells显示文摘Background Studies have shown that oxidized low density lipoprotein (ox-LDL) promotes the pathogenesis and development of atherosclerosis (AS), and that the proliferation, migration and phenotype alteration of vascular smooth muscle cells (vSMCs) into foam cells are critical changes in AS. It is proposed that ox-LDL might play a novel role in the pathologic process of vSMCs. The present study was performed ex vivo to investigate the effects of ox-LDL on the growth of cultured human vSMCs.Methods Using NaBr density gradient centrifugation, LDL from human plasma was isolated and purified. ox-LDL was produced from LDL after being incubated with CuSO4. ox-LDL was then added to the culture medium at different concentrations (25 μg/ml, 50 μg/ml, 75 μg/ml, 100 μg/ml, 125 μg/ml, and 150 μg/ml) for 7 days. The influence of ox-LDL on vSMC growth was observed from several aspects as growth curve, mitosis index, lipid staining, and in situ determination of apoptosis. The digital results were analyzed with SPSS 10.0.Results The ox-LDL produced ex vivo had a good purity and optimal oxidative degree, which was similar to the intrinsic ox-LDL in atherosclerotic plaque. ox-LDL at a concentration of 25 μg/ml demonstrated the strongest proliferation. At the concentration of 125 μg/ml, ox-LDL suppressed the growth of vSMCs. At concentrations of 25 μg/ml and 50 μg/ml, ox-LDL presented powerful mitotic trigger. When the concentration of ox-LDL increased, the mitotic index of vSMCs decreased gradually. ox-LDL induced more foam cells from vSMCs with rich intracellular lipid accumulation at concentrations of 25 μg/ml and 50 μg/ml. ox-LDL at higher concentrations induced more apoptotic vSMCs.Conclusions ox-LDL at lower concentrations may trigger proliferation and phenotype alteration into foam cells of vSMCs, and at higher concentrations it may induce apoptosis in vSMCs. ox-LDL plays an important role in the pathogenesis and development of atherosclerosis by its effect on vSMCs proliferation, phenotype alteration and apoptosis.ZHAO Gao-feng SENG Jing jing ZHANG Hua SHE Ming-peng 2005Chinese Medical Journal2005,,23:14
9Probiotics for gastrointestinal disorders: Proposed recommendations for children of the Asia-Pacific region显示文摘Recommendations for probiotics are available in several regions. This paper proposes recommendations for probiotics in pediatric gastrointestinal diseases in the Asia-Pacific region. Epidemiology and clinical patterns of intestinal diseases in Asia-Pacific countries were discussed. Evidence-based recommendations and randomized controlled trials in the region were revised. Cultural aspects,health management issues and economic factors were also considered. Final recommendations were approved by applying the Likert scale and rated using the GRADE system. Saccharomyces boulardii CNCM I-745(Sb) and Lactobacillus rhamnosus GG(LGG) were strongly recommended as adjunct treatment to oral rehydration therapy for gastroenteritis. Lactobacillus reuteri could also be considered. Probiotics may be considered for prevention of(with the indicated strains): antibiotic-associated diarrhea(LGG or Sb); Clostridium difficile-induced diarrhea(Sb); nosocomial diarrhea(LGG); infantile colic(L reuteri) and as adjunct treatment of Helicobacter pylori(Sb and others). Specific probiotics with a history of safe use in preterm and term infants may be considered in infants for prevention of necrotizing enterocolitis. There is insufficient evidence for recommendations in other conditions. Despite a diversity of epidemiological,socioeconomical and health system conditions,similar recommendations apply well to Asia pacific countries. These need to be validated with local randomized-controlled trials.Donald Cameron Quak Seng Hock Musal Kadim Neelam Mohan Eell Ryoo Bhupinder Sandhu Yuichiro Yamashiro Chen Jie Hans Hoekstra Alfredo Guarino 2017World Journal of Gastroenterology2017,23,45:14
10Construction and Co-expression of Grass Carp Reovirus VP6 Protein and Enhanced Green Fluorescence Protein in the Insect Cells显示文摘Grass carp reovirus(GCRV),a disaster agent to aquatic animals,belongs to Genus Aquareovirus of family Reoviridea.Sequence analysis revealed GCRV genome segment 8(s8) was 1 296 bp nucleotides in length encoding an inner capsid protein VP6 of about 43kDa.To obtain in vitro non-fusion expression of a GCRV VP6 protein containing a molecular of fluorescence reporter,the recombinant baculovirus,which contained the GCRVs8 and eGFP(enhanced green fluorescence protein) genes,was constructed by using the Bac-to-Bac insect expression system.In this study,the whole GCRVs8 and eGFP genes,amplified by PCR,were constructed into a pFastBacDual vector under polyhedron(PH) and p10 promoters,respectively.The constructed dual recombinant plasmid(pFbDGCRVs8/eGFP) was transformed into DH10Bac cells to obtain recombinant Bacmid(AcGCRVs8/eGFP) by transposition.Finally,the recombinant bacluovirus(vAcGCRVs8/eGFP) was obtained from transfected Sf9 insect cells.The green fluorescence that was expressed by transfected Sf9 cells was initially observed 3 days post transfection,and gradually enhanced and extended around 5 days culture in P1(Passage1) stock.The stable high level expression of recombinant protein was observed in P2 and subsequent passage budding virus(BV) stock.Additionally,PCR amplification from P1 and amplified P2 BV stock further confirmed the validity of the dual-recombinant baculovirus.Our results provide a foundation for expression and assembly of the GCRV structural protein in vitro.Qin FANG Eng Khuan Seng Wen DAI Lan-lan ZHANG 2007中国病毒学2007,22,5:13
11盐分对广式高盐稀态酱油发酵微生物菌群结构的影响显示文摘随着健康中国计划的推进,酱油的减盐成为一种趋势,然而广式高盐稀态酱油发酵过程中盐分对不同发酵阶段的群落结构影响的基础研究仍较薄弱,难以支撑减盐酱油产品的普及。该研究基于Illumina HiSeq高通量基因序列分析及理化指标监测,研究不同盐分条件下不同发酵阶段微生物群落结构及理化指标变化规律。结果表明,低盐组(120 g/L)pH值最低,发酵后快速积累总酸、氨基酸态氮和还原糖;在细菌菌群结构方面,随着盐浓度降低,葡萄球菌属(Staphylococcus)、乳球菌属(Lactococcus)、乳杆菌属(Lactobacillus)均在低盐酱醪中持续增长;在真菌群落构成方面,假丝酵母属(Candida)和米勒氏酵母属(Millerozyma)含量在低盐组酱醪中明显较高。低盐(120 g/L)酱醪发酵中乳酸菌含量及总酸明显比中盐(150 g/L)及高盐(170 g/L)组较高,并在发酵初期快速形成了更加适合酵母菌目生长的酸性环境,促进酵母菌目在发酵中期形成了明显的优势菌群。该研究结果为减盐发酵提供了理论基础,为进一步开发酱油低盐发酵微生物调控技术提供参考依据。TIN Hoe Seng 周斌 侯莎 吴昌正 黄磊 周其洋 2022食品与发酵工业2022,48,1:11

13Return to sport following tibial plateau fractures: A systematic review显示文摘AIM To systemically review all studies reporting return to sport following tibial plateau fracture, in order to provide information on return rates and times to sport, and to assess variations in sporting outcome for different treatment methods.METHODS A systematic search of CINAHAL, Cochrane, EMBASE, Google Scholar, MEDLINE, PEDro, Scopus, SPORTDiscus and Web of Science was performed in January 2017 using the keywords 'tibial', 'plateau', 'fractures', 'knee', 'athletes', 'sports', 'non-operative', 'conservative', 'operative', 'return to sport'. All studies which recorded return rates and times to sport following tibial plateau fractures were included. RESULTS Twenty-seven studies were included: 1 was a randomised controlled trial, 7 were prospective cohort studies, 16 were retrospective cohort studies, 3 were case series. One study reported on the outcome of conservative management(n = 3); 27 reported on the outcome of surgical management(n = 917). Nine studies reported on Open Reduction Internal Fixation(ORIF)(n = 193), 11 on Arthroscopic-Assisted Reduction Internal Fixation(ARIF)(n = 253) and 7 on Frame-Assisted Fixation(FRAME)(n = 262). All studies recorded 'return to sport'rates. Only one study recorded a 'return to sport' time. The return rate to sport for the total cohort was 70%. For the conservatively-managed fractures, the return rate was 100%. For the surgically-managed fractures, the return rate was 70%. For fractures managed with ORIF, the return rate was 60%. For fractures managed with ARIF, the return rate was 83%. For fractures managed with FRAME was 52%. The return rate for ARIF was found to be significantly greater than that for ORIF(OR 3.22, 95%CI: 2.09-4.97, P < 0.001) and for FRAME(OR 4.33, 95%CI: 2.89-6.50, P < 0.001). No difference was found between the return rates for ORIF and FRAME(OR 1.35, 95%CI: 0.92-1.96, P = 0.122). The recorded return time was 6.9 mo(median), from a study reporting on ORIF.CONCLUSION Return rates to sport for tibial plateau fractures remain limited compared to other fractures. ARIF provides the best return rates. There is limited data regarding return times to sport. Further research is required to determine return times to sport, and to improve return rates to sport, through treatment and rehabilitation optimisation.Greg A J Robertson Seng J Wong Alexander M Wood 2017World Journal of Orthopedics2017,8,7:10
14Gastro-intestinal toxicity of chemotherapeutics in colorectal cancer:The role of inflammation显示文摘Chemotherapy-induced diarrhea(CID)is a common and often severe side effect experienced by colorectal cancer(CRC)patients during their treatment.As chemotherapy regimens evolve to include more efficacious agents,CID is increasingly becoming a major cause of dose limiting toxicity and merits further investigation.Inflammation is a key factor behind gastrointestinal(GI)toxicity of chemotherapy.Different chemotherapeutic agents activate a diverse range of pro-inflammatory pathways culminating in distinct histopathological changes in the small intestine and colonic mucosa.Here we review the current understanding of the mechanisms behind GI toxicity and the mucositis associated with systemic treatment of CRC.Insights into the inflammatory response activated during this process gained from various models of GI toxicity are discussed.The inflammatory processes contributing to the GI toxicity of chemotherapeutic agents are increasingly being recognised as having an important role in the development of anti-tumor immunity,thus conferring added benefit against tumor recurrence and improving patient survival.We review the basic mechanisms involved in the promotion of immunogenic cell death and its relevance in the treatment of colorectal cancer.Finally,the impact of CID on patient outcomes and therapeutic strategies to prevent or minimise the effect of GI toxicity and mucositis are discussed.Chun Seng Lee Elizabeth J Ryan Glen A Doherty 2014World Journal of Gastroenterology2014,20,14:10

20Factors associated with significant liver fibrosis assessed using transient elastography in general population显示文摘AIM: To investigate the prevalence of significant liver fibrosis assessed using transient elastography(TE) and its predictors in asymptomatic general population.METHODS: A total of 159 subjects without chronic viral hepatitis who underwent comprehensive medical health check-up between January 2012 and July 2012 were prospectively recruited. Significant liver fibrosis was defined as liver stiffness value > 7.0 k Pa.RESULTS: The mean age and body mass index(BMI) of the study population(men 54.7%) was 56.0 years and 24.3 kg/m2. Among the study subjects, 11(6.9%) showed significant liver fibrosis. On univariate analysis, BMI, alanine aminotransferase(ALT), homeostasis model assessment of insulin resistance, carotid intimal media thickness(IMT), number of calcified plaques on carotid ultrasound, and visceral fat area on computed tomography were significantly higher in subjects with significant liver fibrosis than in those without(all P < 0.05). However, on multivariate analysis, BMI [odds ratio(OR) =1.487; P = 0.045], ALT(OR = 1.078; P = 0.014), carotid IMT(OR = 3.244; P = 0.027), and the number of calcified carotid plaques(OR = 1.787; P = 0.031) were independent predictors of significant liver fibrosis. CONCLUSION: The prevalence of significant liver fibrosis assessed using TE was 6.9% in apparently healthy subjects. High BMI, high ALT, thicker carotid IMT, and higher numbers of calcified carotid plaqueswere independently associated with the presence of significant liver fibrosis.Seng Chan You Kwang Joon Kim Seung Up Kim Beom Kyung Kim Jun Yong Park Do Young Kim Sang Hoon Ahn Won Jae Lee Kwang-Hyub Han 2015World Journal of Gastroenterology2015,21,4:7
