The role of scintigraphic imaging has moved from the detection of lesions to the tissue-specific characterization of lesions over the past 2 decades. Major advances in nuclear medicine imaging include: 1) positron imaging, 2) improved instrumentation, such as the use of multidetector (dual or triple head) gamma cameras for single photon emission computed tomography, and 3) development of numerous new radiopharmaceuticals for positron or single photon imaging ( labeled glucose analogue, amino acids, fatty acids, hormones, drugs, receptor ligands, monoclonal antibodies, etc). These advanced have resulted in a significantly improved efficacy of radionuclide techniques for the evaluation of various of focal gepatic tumors is reviewed in this article with an emphasis on the clinical applications of various tracer studies and imaging findings.

BACKGROUND: The development and progression of a tumor can be determined by a complex multistep process involving the activation of oncogenes and the inactivation of tumor suppressor genes. The purpose of this study is to investigate the expression of p53, Rb, bcl-2 protein and Ki-67 labeling index in the intrahepatic cholangiocarcinoma. METHODS: We analyzed 36 cases of intrahepatic cholangiocarcinoma obtained by surgical resection. Expression of p53, Rb, bcl-2 proteins and Ki-67 labeling index were evaluated by immunohistochemical study. RESULTS: Expression of p53 protein was detected in 61.1% (22/36) of cholangiocarcinoma. Rb protein loss and overexpression were observed 27.8% (7/36) and 72.2% (29/36) of cholangiocarcinoma. But bcl-2 protein was not expressed. No significant correlation was found between p53, Rb and bcl-2 protein expression and age, sex, gross type, histologic grade, vascular invasion and lymph node metastases. The Ki-67 labeling index was significantly higher in p53 positive group and Rb overexpression group than in p53 negative group (p<0.01) and Rb loss group (p<0.05). There was a positive correlation between p53 protein and Rb protein expressions, but a negative correlation between Rb protein and bcl-2 protein expressions. CONCLUSIONS: The overexpression of p53 protein and Rb protein may be closely associated with cholangiocarcinogenesis, while bcl-2 has a less crucial role in cholangiocarcinogenesis.

PURPOSE: The purpose of this study was to identify the moderating and mediating effects of resilience in the relationship between emotional labor and job satisfaction among nurses working in intensive care units (ICUs).METHOD: The participants were 144 ICU nurses from three university hospitals. Data were collected using structured questionnaires and analyzed by t-test, ANOVA, Scheffé test, Pearson correlation coefficients, and multiple regression analysis, using SPSS 25.0. The mediating effect of resilience in the relationship between emotional labor and job satisfaction was analyzed by multiple regression analysis according to Baron and Kenny's procedure.RESULTS: Statistically significant negative correlations were found between emotional labor and resilience (r=−.21, p<.014) and between emotional labor and job satisfaction (r=−.34, p<.001). A significant positive correlation was found between resilience and job satisfaction (r=.31 p<.001). A partial mediating effect by resilience was found between emotional labor and job satisfaction (Z=−2.11, p =.034), but no moderating effect was found.CONCLUSION: To improve the job satisfaction of ICU nurses, evaluation of their emotional labor, resilience, and interventions are necessary to alleviate emotional labor and improve resilience.

A 13-month-old boy had irregularly shaped, erythematous to dusky red, slightly raised patches and plaques on the left antecubital fossa and arm for 7 months. The lesions were firm and tender. Histopathologically the lesion consisted of small, circumscribed, angiomatous tufts and lobules with a cannonball appearance scattered throughout dermis, a characteristic feature of tufted angioma. For 15 weeks, interferon-a intralesional injections have been performed and the lesions showed an improvement.

In the 1920's, Warburg reported an observation that cancer cells depend on glycolysis even in the presence of available oxygen likely due to impaired function of mitochondria. Since then, this Warburg s effect has been the most important hypothesis in cancer metabolism and is considered as a seventh hallmark of many human cancers. Aerobic glycolysis was originally attributable to increased bioenergetic needs in rapidly proliferating cancer cells. Recently, biosynthetic aspects of aerobic glycolysis, which reprograms cancer metabolism to synthesize macromolecules such as nucleotides, fatty acids, amino acids, etc., are under active investigation. Introduction of positron emission tomography (PET) and metabolic radiotracers including F-18 flurorodeoxyglucose (FDG) and C-11 acetate made it possible to image cancer metabolism in vivo and to renew the interests on this issue. Studies have found that cancer cells with highly glycolysis features are associated with resistance to many chemotherapeutic regimens and radiation treatment. Therefore, development of glycolytic inhibitors can have an incremental effect to conventional treatments. In addition, functional imaging with metabolic radiotracers will continuously play important roles in detecting cancers and monitoring therapeutic responses to novel anti-metabolic approaches to cancer cells.
