动态话语中隐喻的鉴别机制
1
作者 王东梅 《长春理工大学学报(社会科学版)》 2011年第2期63-66,共4页
对在动态话语中产生的语言隐喻进行研究突破了国内隐喻研究的局限性。研究隐喻首先须建立有效的隐喻鉴别机制,从隐喻鉴别的效度及信度两方面考虑,才能保证不忽略任何一个值得探讨的隐喻。

AIM:To determine whether trefoil factor 1 (TFF1) is associated with mucosa healing and carcinoma suppression, we assess the expression of trefoil factor 1 in normal and pathologic gastric mucosa. METHODS: TFF1 in normal and pathologic gastric mucosa was assessed by immunohistochemical method, and the average positive A was estimated by Motic Images Advanced 3.0 software. RESULTS: Increased TFF1 was detected in gastritis, gastric ulcer and duodenal ulcer compared with normal mucosa. The same result could be seen in multiple and compound ulcer compared with simple ulcer. There was no significant difference between gastric ulcer and duodenal ulcer, gastritis and simple ulcer respectively. Increased TFF1 was detected in the peripheral mucosa of the gastric adenocarcinoma compared with normal mucosa. The expression of TFF1 in gastric adenocarcinoma was related to the differentiation of adenocarcinoma. The lower the differentiation of adenocarcinoma, the weaker the expression of TFF1. There was no TFF1 expressed in low-differentiated adenocarcinoma. The expression of TFF1 in middle and highly differentiated adenocarcinoma was a little lower than that in normal mucosa. But there was no significant difference. No TFF1 was assessed in esophageal squamous carcinoma and peripheral tissue. There was no significant difference between male and female. CONCLUSION: The expression of TFF1 was higher in gastritis and peptic ulcer than that in normal mucosa, and was also higher in multiple and compound ulcer than in simple ulcer. It seems that TFF1 plays a role in gastric mucosa protection and epithelial restitution. Increased expression of TFF1 in peripheral tissue suggests that TFF1 is associated with mechanism of carcinoma suppression and differentiation. Decreased expression of TFF1 in carcinoma and its relativity to the differentiation suggests that TFF1 is related to gland and cell destruction of carcinoma. 展开更多

Recognition and management of gastrointestinal and hepatic complications of hematopoietic stem cell transplantation has gained increasing importance as indications and techniques of transplantation have expanded in the last few years.The transplant recipient is at risk for several complications including conditioning chemotherapy related toxicities,infections,bleeding,sinusoidal obstruction syndrome,acute and chronic graftversus-host disease(GVHD) as well as other long-term problems.The severity and the incidence of many complications have improved in the past several years as the intensity of conditioning regimens has diminished and better supportive care and GVHD prevention strategies have been implemented.Transplant clinicians,however,continue to be challenged with problems arising from human leukocyte antigen-mismatched and unrelated donor transplants,expanding transplant indications and age-limit.This review describes the most commonly seen transplant related complications,focusing on their pathogenesis,differential diagnosis and management. 展开更多

AIM: To identify the misperceptions among CHB patients,as well as to determine the factors associated with betterknowledge.METHODS: A telephone interview was conducted on 292 adult CHB patients, who earlier responded to an advertisement for free screening. The questionnaire included items about socio-demographic factors and a24-item quiz on knowledge of general aspects,transmission, and management of HBV infection.RESULTS: The mean knowledge score on HBV was 10.4/14. Common misperceptions included availability of treatment for HBV infection and early liver cancer, as well as on transmission. Having completed tertiary education was the only independent factor associated with a high knowledge score, after controlling other demographic factors.CONCLUSION: More educational efforts should be focused on patients' misperceptions and target the less educated HBV carriers. 展开更多

Objective To investigate the diagnostic and treatment methods of Castleman's disease(CD).Methods Five CD cases were treated in our department,we presented its clinical characteristics and had a comprehensive review of different reports from other centers.Results We presented five patients who had retroperitoneal mass and postoperative pathological results confirmed all of them had hyaline vascular(HV)type CD.We also discussed CD by reviewing different literatures on its diagnosis,treatment and outcome.Conclusion CD is an atypical lymphoproliferative disorder and a heterogeneous entity that can be either localized or systematic.The etiology and pathogenesis of this entity is still unclear.The imaging findings though are not specific,still can help make differential diagnosis.The hyaline vascular type frequently appears as a benign isolated mediastinal or rarely retroperitoneal mass,which does not recur after curative surgical excision. 展开更多
