＜正＞ the realization of all-optical switching, modulating and computing devices is an important goal in modern optical technology. Nonlinear optical materials with large third-order nonlinear susceptibilities （··（3）） are indispensable for such devices, because the magnitude of this quantity dominates the devices performance. A key strategy in the development of new materials with large nonlinear susceptibilities is the exploration of quasi-one-dimensional systems, or "quantum wires" - the quantum confinement of electron-hole motion in one-dimensional space can enhance ··（3）. two types of chemically synthesized quantum wires have been extensively studied: the band insulators of silicon polymers, and Peierls insulators of ·-conjugated polymers and

世界核心医学期刊文摘（胃肠病学分册） 2006年第3期2卷 53-54页

Background: Recent reports suggest that Helicobacter pylori infection can potentially increase the risk of colorectal cancer. the purpose of this study was to assess the association between H. pylori infection and the risk of colorectal adenoma and adenocarcinoma, and to evaluate any differences on the basis of sex. Methods: the subjects were 669 (40-to 80-year-old) patients who underwent both barium enema examination and total colonoscopy, and who were evaluated for H. pylori infection by 13C-urea breath test, urease test, or histological diagnosis of biopsied gastric specimens. there were 142 H. pylori-negative and 527-positive patients. the odds ratios (ORs) for H. pyloripositive patients with colorectal adenoma and adenocarcinoma, and for tumor patients with either adenoma or adenocarcinoma were calculated. Results: Among the H. pylori-negative patients, there were 52 patients without tumor, 63 with adenoma, 27 with adenocarcinoma, and 90 with tumor. Among the H. py-lori-positive patients, there were 136, 264, 127, and 391 patients respectively. Pooling all subjects, those infected with H. pylori had a significantly increased OR for adenoma, adenocarcinoma, or tumor, compared to H. pylori-free patients (OR, 1.60, 1.80, and 1.66, respectively). For female H. pylori-positive subjects, the risk of having adenocarcinoma or tumor was significantly higher than that for their H. pylori-free counterparts, while for male H. pylori-positive and -negative subjects, there was no such significant difference. Conclusions: the results therefore suggest that, in patients aged 40-80 years, H. pylori infection increased the risk of colorectal adenoma and adenocarcinoma, with significantly higher risks for female patients.

U波产生的机理尚未明确.有两种主要学说,一种认为U波产生于心室舒张的机械性结果,另一种则认为与浦顷野纤维复极有关.正常U波向量大致与t波向量平行,任何一个导联出现U波倒置即属异常.U波倒置是提示有心脏病存在的一个高度特异的指标,很少见于无心脏病或其它心电图异常时.本文488名U波倒置病例多数在40～80岁之间,以高血压病(193例)、缺血性心脏病(162例)以及主动脉瓣与二尖瓣关闭不全(56例)最为多见,仅35例无心脏病.除25例(5%)外,均同时有其他心电图异常.
