AIM： To determine the effect of melatonin pre- and post-treatment on the severity of L-arginine （L-Arg） -induced experimental pancreatitis in rats. METHODS： Male Wistar rats （25） were divided into five groups. Those in group A received two injections of 3.2 g/kg body weight L-Arg i.p. at an interval of 1 h. In group MA, the rats were treated with 50 mg/kg body weight melatonin i.p. 30 min prior to L-Arg administration. In group AM, the rats received the same dose of melatonin 1 h after L-Arg was given. In group M, a single dose of melatonin was administered as described previously. In group C the control animals received physiological saline injections i.p. All rats were exsanguinated 24 h after the second L-Arg injection. RESULTS： L-Arg administration caused severe necrotizing pancreatitis confirmed by the significant elevations in the serum amylase level, the pancreatic weight/body weight ratio （pw/bw）, the pancreatic IL-6 content and the myeloperoxidase activity, relative to the control values. Elevation of the serum amylase level was significantly reduced in rats given melatonin following L-Arg compared to rats injected with L-Arg only. The activities of the pancreatic antioxidant enzymes （Cu/Zn-superoxide dismutase （CulZn-SOD） and catalase （CAT）） were significantly increased 24 h after pancreatitis induction. Melatonin given in advance of L-Arg significantly reduced the pancreatic CAT activity relative to that in the rats treated with L-Arg alone. In the liver, L-Arg significantly increased the lipid peroxidation level, and the glutathione peroxidase and Cu/Zn-SOD activities, whereas the Mn-SOD activity was reduced as compared to the control rats. Melatonin pre-treatment prevented these changes. CONCLUSION： Melatonin is an antioxidant that is able to counteract some of the L-Arg-induced changes during acute pancreatitis, and may therefore be helpful in the supportive therapy of patients with acute necrotizing pancreatitis.

采用***非线性有限元软件,对试件在激光点热源作用下动态微变形过程进行了数值模拟。通过激光反射放大系统测量了试件在激光点热源作用下的动态微变形过程。模拟值与实测值的结果表明:热应力和相变应力的共同作用使得试件产生微变形,最终试件的变形方向取决于热应变和相变共同作用的结果,朝向激光束或背向激光束。比较实验值和模拟值,发现变形的最大值相近,变形过程却略有不同。考虑到激光点热源作用下有限厚度的试件内,温度场分布出现的反常效应,即内部的温度大于边界温度,提出采用波动理论修正经典的热传导计算模型,可望有效地提高模拟过程的计算精度。结论为进一步研究薄板激光弯曲的变形机理及变形过程奠定了基础。

通过红外热像仪测温装置,对有限厚度试件在激光点热源作用下热作用区侧面温度分布进行实时测量。结果表明:对于小厚度的试件,材料内部温度分布与用傅立叶定律得到的结果完全相反,材料内部的温度高于边界温度。对比短脉冲激光作用下产生非傅立叶效应的条件,它们之间有很大差异,由此提出将实验中出现的非常规现象定义为泛傅立叶效应,认为它是由于热量传播到边界时发生反射、叠加等波动行为所致。

Remarkable progress has been made in molecular characterization of prostate cancer （PCa） with continued innovations in high throughput technologies evaluating human cancer？-3 Since the completion of the Human Genome Project it has been estimated that only about 1.5%-2% of our genome codes for proteins. Various genome-wide approaches, e.g. the ENCODE project, revealed that a much larger percent of the genome is transcribed as non-protein coding （nc） RNA, including long noncoding （lnc） RNA （over 200bps long）. Although the biological roles of IncRNA （the ＇dark matter of the genome＇） are not nearly as well-understood as the protein coding mRNAs, it is increasingly clear that they play important roles in almost every aspects of biology, including cancer biology.4＇5 This is exemplified by recent genome-wide association studies revealing that over 80% of cancer-associated single nucleotide polymorphisms （SNPs） are in noncoding regions of the genome.

Eosinophilic colitis

World Journal of Gastroenterology 2009年第24期15卷 2975-2979页

作者： Nnenna Okpara Bassam Aswad gyorgy Baffy Division of Gastroenterology Department of Medicine Rhode Island Hospital and Alpert Medical School of Brown University Department of Pathology Rhode Island Hospital and Alpert Medical School of Brown University

Eosinophilic colitis (EC) is a rare form of primary eosinophilic gastrointestinal disease with a bimodal peak of prevalence in neonates and young adults. EC remains a little understood condition in contrast to the increasingly recognized eosinophilic esophagitis. Clinical presentation of EC is highly variable according to mucosal, transmural, or serosal predominance of inflammation. EC has a broad differential diagnosis because colon tissue eosinophilia often occurs in parasitic infection, drug-induced allergic reactions, inflammatory bowel disease, and various connective tissue disorders, which require thorough searching for secondary causes that may be specifically treated with antibiotics or dietary and drug elimination. Like eosinophilic gastrointestinal disease involving other segments of the gastrointestinal tract, EC responds very well to steroids that may be spared by using antihistamines, leukotriene inhibitors and biologics.
