H. pylori can be a pathogen and causes development of peptic ulcer disease in a certain state of the macroorganism. It is well established that H. pylori infection is the main cause of chronic gastritis and peptic ulcer disease(PUD). Decontamination of the gastric mucosa with various antibiotics leads to H. pylori elimination and longer remission in this disease. However,the reasons for repeated detection of H. pylori in recurrent PUD after its successful eradication remain unclear. The reason for the redetection of H. pylori in recurrent PUD can be either reinfection or ineffective anti-Helicobacter therapy. The administration of antibacterial drugs can lead not only to the emergence of resistant strains of microorganisms,but also contribute to the conversion of H. pylori into the resting(dormant) state. The dormant forms of H. pylori have been shown to play a potential role in the development of relapses of PUD. The paper discusses morphological H. pylori forms,such as S-shaped,C-shaped,U-shaped,and coccoid ones. The authors proposes the classification of H. pylori according to its morphological forms and viability.展开更多

The pathological documents were supplied by the Department of Pathology, West China Hospital, and other necessary data were extracted from the hospital records. The statistical analyses were performed by survival analysis （Kaplan-Meier method）, descriptive statistical analyses and Х^2 analysis.RESULTS： The neuroendocrine marker vimentin was found to be selectively expressed in the benign tumors, and there were significant differences in the expression of those markers in both benign and malignant tumors. The survival analysis revealed that survival correlated significantly with the malignancy, metastasis and nodal status.CONCLUSION： Vimentin may be useful in the differential diagnosis between malignant and benign tumors. The difference in the expression of this marker in the tumors could be a clue to the future clinical diagnosis. The malignancy, metastasis and the nodal status may predict the prognosis of this disease.展开更多

It discusses two typological models dealing with the basic metaphysical problem concerned with the presence and meaning of transcendence in real human existence. According to the first, the historical reality of secularization causes a break from the collective memory whose roots are in religion. In contrast, the second model considers that despite the deep transformations in the status of religion in a reality of secularization, an experience of historical continuity may also occur there. These models denote the two poles in the argument about the meaning and value of history for modem people. The article suggests a phenomenological analysis of the two models and criticizes their deficiencies. Finally, the ＂tension model＂ is outlined as a third alternative that aims at overcoming the binary situation created by the first two in favor of a perspective that necessitates and contains both immanence and transcendence.展开更多

In keeping with Marianne Hirsch＇s notion of ＂postmemory＂, this paper argues that cinema, as a visual form of artistic mediation, has an especially strong impact on the spectator, because it triggers affective, tactile, and bodily responses. Hence, the efficacy of generating an ethics of remembrance of sexually-related violence, based on cinematic aesthetics, which the author terms here ＂cinememory＂. The paper focuses on a sub-genre of Holocaust-related films： coming-of-age films, which explore in different ways the lasting implications of growing-up in the shadow of sexualized trauma; the unconscious transmission of memories and tactile experiences, related to the ubiquity of sexual violence during the Holocaust.展开更多

Methods: Between December 2000 and December 2002, 24 cemented total knee arthroplasty in 21 patients were performed using all-polyethylene tibial components. The mean age of the 21 patients (9 men and 12 women) at operation was 55 years, ranging 48-61 years. The mean preoperative hospital for special surgery (HSS)score was 40.2 (range, 36-43). The diagnoses were degenerative osteoarthritis in 15 patients, rheumatoid arthritis in 5 and traumatic arthritis in 1. All the operations were performed by the same surgeon group and there were unilateral operations in 18 patients and bilateral operations in 3. Results: Eighteen patients were followed up with a follow-up rate of 85.7%. The mean follow-up is 2.5 years (range, 1-3 years) and mean postoperative HSS scores was 87.5 (range, 83-89). Among them, 18 were excellent, 3 good, 3 poor and none was fair (the results of three lost patients were classified as poor). Of those reviewed, the prosthesis was all in situ and no revision occurred. Radiological assessment of these patients revealed 4 ( 16.67%) tibial components with radiolucent lines (mean width≤2 mm) distributed mainly in zone 1 and zone 4. None of these knees was symptomatic. Conclusions: The result of total knee arthroplasty using all-polyethylene tibial components is encouraging. The operative techniques are similar to those in arthroplasty using metal-backed tibial component.展开更多
