1RegCM3对东亚环流和中国气候模拟能力的检验显示文摘使用RegCM3区域气候模式,嵌套ERA40再分析资料,对东亚地区进行了15年(1987~2001年)时间长度的数值积分试验,分析了模式对东亚平均环流及中国地区气温和降水的模拟。结果表明,模式对东亚平均环流的特征和中国地区降水、地面气温的年、季地理分布和季节变化特征均具有一定的模拟能力,对气温和降水年际变率的模拟也较好。此外模式模拟在测站稀少地区,可以提供局地如降水分布更可靠的信息。模式对气温的模拟存在1-3℃的系统性冷偏差;对中国地区降水地理分布的模拟也存在一定偏差,如对年平均降水的模拟中,降水最大值位置与观测有一定差距,特别是对冬季降水中心的模拟存在较大偏差。模式模拟的夏季降水,在中国北方地区总体偏大100-200 mm,南方总体偏小100-200 mm。模式对地面气温的模拟效果好于降水。张冬峰 欧阳里程 高学杰 赵宗慈 PAL Jeremy S GIORGI Filippo 2007热带气象学报2007,23,5:70
2Function of longitudinal vs circular muscle fibers in esophageal peristalsis, deduced with mathematical modeling显示文摘We summarize from previous works the functions of circular vs. longitudinal muscle in esophageal peristaltic bolus transport using a mix of experimental data, the conservation laws of mechanics and mathematical modeling. Whereas circular muscle tone generates radial closure pressure to create a local peristaltic closure wave, longitudinal muscle tone has two functions, one physiological with mechanical implications, and one purely mechanical. Each of these functions independently reduces the tension of individual circular muscle fibers to maintain closure as a consequence of shortening of longitudinal muscle locally coordinated with increasing circular muscle tone. The physiological function is deduced by combining basic laws of mechanics with concurrent measurements of intraluminal pressure from manometry, and changes in cross sectional muscle area from endoluminal ultrasound from which local longitudinal shortening (LLS) can be accurately obtained. The purely mechanical function of LLS was discovered from mathematical modeling of peristaltic esophageal transport with the axial wall motion generated by LLS. Physiologically, LLS concentrates circular muscle fibers where closure pressure is highest. However, the mechanical function of LLS is to reduce the level of pressure required to maintain closure. The combined physiological and mechanical consequences of LLS are to reduce circular muscle fiber tension and power by as much as 1/10 what would be requiredfor peristalsis without the longitudinal muscle layer, a tremendous benefit that may explain the existence of longitudinal muscle fiber in the gut. We also review what is understood of the role of longitudinal muscle in esophageal emptying, reflux and pathology.James G Brasseur Mark A Nicosia Anupam Pal Larry S Miller 2007World Journal of Gastroenterology2007,13,9:4
3印度Ganga-Meghna-Brahmaputra平原及周围地区与孟加拉国地下水砷污染及其对健康影响的19年研究显示文摘基于近19年对印度Ganga—Meghna—Brahmaputra(简称GMB)平原(面积569749km^2,人口超过5亿)地下水砷污染的调查,可以确定印度Ganga—Brahmaputra平原(包括北方邦、比哈尔邦、恰尔康得邦、西孟加拉邦、阿萨姆邦)和孟加拉国普遍受到砷的污染。近期的调查研究也表明,除米佐拉姆邦外,其他各邦的地下水也受到不同程度的砷污染。至今为止.已对印度各邦和孟加拧国的175000份和50808份压把井水样进行了含砷量检测。并组织了一支包括皮肤科、神经科和妇产科医生在内的有经验的专家组,对上述地区125000人进行了临床检查,其中9%患有砷导致的皮肤病损症状。至今共采集分析了60000份生物样品。包括发样、指甲、尿样及皮肤鳞屑,其中80%的样品含砷量超过允许值,很多人由此受到砷的亚临床损害。在上述砷暴露地区.19000名儿童经过检查,近1100人患有砷导致的皮肤病损。该调查结果表明.儿童比成人更容易受到砷的毒性损害。在这种状况下.应着力解决饮水安全问题来减轻砷的苊害.Ahamed S Hossain MA Mukharjee A Sengupta MK Das B Nayak B Pal A Mukherjee SC Pati S Dutta RN Saha KC Quamruzzaman Q Chakraborti D 付松波(译) 孙殿军(审校) 2007中国地方病学杂志2007,26,1:3
4Role of N-acetylcysteine in rifampicin-induced hepatic injury of young rats显示文摘瞄准:为了是学习 N-acetylcysteine (NAC ) 的角色,在 rifampicin (RMP ) 的一个保护的代理人导致了小老鼠的氧化肝的损害。方法:肝的损害被为 3 wk 给 RMP 的 50 mg/kg 体重生产。NAC (100 mg/kg 体重) 的剂量 intraperitoneally 与 RMP 在联合被给。类脂化合物的分析与体重,肝重量和组织学的观察一起在肝每氧化,巯基层次,细胞色素 P450,超级氧化物歧化酶(草皮) ,过氧化氢酶,谷胱甘肽过氧化物酶,还原酶和转移酶被估计。结果:当抗氧化的酶被改变时, RMP 暴露在身体和肝重量导致了没有变化但是非,蛋白质巯基(GSH ) 地位很好被保存。细胞色素 P450 系统并且每类脂化合物的氧化被 RMP 暴露导致。部分保护在肝对导致 RMP 的变化与 NAC 被观察,它在草皮和过氧化氢酶酶层次每氧化和减小从类脂化合物的增加的预防被证实。结论:NAC 保护小老鼠免于导致 RMP 的氧化肝的损害。SV Rana S Attri K Vaiphei R Pal A Attri K Singh 2006World Journal of Gastroenterology2006,12,2:3

7NKX2-3 and IRGM variants are associated with diseasesu sceptibility to IBD in Eastern European patients显示文摘AIM: To investigate variants of immunity-related GT-Pase family M (IRGM) and NKX2-3 genes and genotype-phenotype in Eastern European patients with inflammatory bowel disease (IBD).METHODS: We analyzed 1707 Hungarian and Czech subjects with Crohn’s disease (CD) (n = 810, age: 37.1 ± 12.6 years, duration: 10.7 ± 8.4 years) and ulcerative colitis (UC) (n = 428, age: 43.7 ± 15.0 years, duration: 12.6 ± 9.9 years), as well as 469 healthy controls. IRGM rs13361189, NKX2-3 rs10883365 and ECM1 rs13294 polymorphisms were tested by LightCy-cler allele discrimination. Detailed clinical phenotypes were determined by reviewing the medical charts. RESULTS: NKX2-3 rs10883365 variant allele was as-sociated with increased risk for CD (P = 0.009, OR = 1.24, 95% CI = 1.06-1.48) and UC (P = 0.001, OR = 1.36, 95% CI = 1.13-1.63), whereas variant IRGM allele increased risk for CD (P = 0.029, OR = 1.36, 95% CI = 1.03-1.79). In contrast, ECM1 rs13294 was not associat-ed with either CD or UC. In CD, the variant IRGM allele was associated with a colon-only location (P = 0.02, OR = 1.62, 95% CI = 1.07-2.44), whereas in UC, the ECM1 variant was associated with cutaneous manifestations (P = 0.002, OR = 3.36, 95% CI = 1.48-7.63). Variant alleles did not predict resistance to steroids or azathio-prine, efficacy of infliximab, or need for surgery. CONCLUSION: NKX2-3 and IRGM are susceptibility locifor IBD in Eastern European patients. Further studies are needed to confirm the reported phenotype-genotype associations.Nora Meggyesi Lajos S Kiss Magdalena Koszarska Martin Bortlik Dana Duricova Laszlo Lakatos Tamas Molnar Martin Lenicek Libor Vítek Istvan Altorjay Maria Papp Zsolt Tulassay Pal Miheller Janos Papp Attila Tordai Hajnalka Andrikovics Milan Lukas Peter Laszlo Lakatos 2010World Journal of Gastroenterology2010,16,41:2
