| 1 | A case of hypereosinophilic syndrome presenting with intractable gastric ulcers显示文摘We report a rare case of hypereosinophilic syndrome(HES)presenting with intractable gastric ulcers.A 71-year-old man was admitted with epigastric pain.Initial endoscopic findings revealed multiple,active gastric ulcers in the gastric antrum.He underwent Helicobacter pylori(H pylori)eradication therapy followed by proton pump inhibitor(PPI)therapy.However,follow-up endoscopy at 4,6,10 and 14 mo revealed persistent multiple gastric ulcers without significant improvement.The proportion of his eosinophil count increased to 43%(total count:7903/mm 3).Abdominal-pelvic and chest computed tomography scans showed multiple small nodules in the liver and both lungs.The endoscopic biopsy specimen taken from the gastric antrum revealed prominent eosinophilic infiltration,and the liver biopsy specimen also showed eosinophilic infiltration in the portal tract and sinusoid.A bone marrow biopsy disclosed eosinophilic hyperplasia as well as increased cellularity of 70%.The patient was finally diagnosed with HES involving the stomach,liver,lung,and bone marrow.When gastric ulcers do not improve despite H pylori eradication and prolonged PPI therapy,infiltrative gastric disorders such as HES should be considered. | Tae Young Park Chang Hwan Choi Suh Yoon Yang InSoo Oh In-Do Song Hyun Woong Lee Hyung Joon Kim Jae Hyuk Do Sae Kyung Chang Ah Ra Cho Young Joo Cha | 2009 | World Journal of Gastroenterology2009，15，48： | 2 |

| 3 | 吸烟与不吸烟者尿液中的烟碱与可替宁含量的比较研究显示文摘此项研究通过测定尿液中烟碱与可替宁含量来评估卷烟烟气与环境烟气 (ETS)对人体的影响。共收集了 1 2 9个尿样 ,这些尿样是根据人的性别、年龄、吸烟年限、平均日消耗烟支数和家庭吸烟人数等特征进行采集的。采集后的尿样先通过Extrelut柱 ,然后用GC/NPD来分析尿样中烟碱和可替宁的含量。在吸烟者的尿样中 ,烟碱和可替宁平均浓度分别为5 .38μg/ml和 3.1 4μg/ml。男性不吸烟者尿液中烟碱和可替宁的平均浓度分别为 0 .1 8μg/ml和0 .0 7μg/ml。吸烟者尿液中烟碱和可替宁含量取决于日消耗烟支数 ,而且 ,吸烟者尿液中烟碱含量和日平均消耗烟支数有直接关系。非吸烟者尿样中烟碱和可替宁来源可能为食物、饮料和ETS。研究结果表明 ,家庭中吸烟者的人数对不吸烟者尿液中烟碱和可替宁浓度的增加没有影响。 | MoonSoo Rhee Do young Ra KeonJoong Hwang 韩红娜 | 2000 | 烟草科技2000，33，2： | 0 |
