Aim
Leukocyte-associated immunoglobulin-like receptor-1 (LAIR-1) is an immune inhibitory receptor which is expressed within most types of hematopoietic cells and negatively regulates immune responses. Recently, we found LAIR-1 expression to be present within tumors of nonhematopoietic lineages. However, the roles of LAIR-1 in hepatocellular carcinoma (HCC) have yet to be examined. The purpose of this study was to investigate the expression of LAIR-1 in HCC tissue and assess its clinical significance at this site.Materials and methods
Expression levels of LAIR-1 within HCC samples collected from 90 patients and compared with that of slides of normal liver tissue collected from 9 non-HCC patients were measured by immunohistochemistry using tissue microarrays. A semiquantitative score was assigned, as was based on staining intensity and percent of positive cells and a Spearman Rank correlation test was used to assess any potential significant correlations between LAIR-1 expression and clinicopathological factors. Overall survival analysis was performed using the Kaplan-Meier and Log Rank statistical test.Results
LAIR-1 expression was detected in cancer tissue and adjacent tumor tissue, but not in normal liver tissue. The percent of LAIR-1-positive expression in cancer tissue of HCC samples was 97.78% (88/90) while that in adjacent tumor tissue was 96.67% (87/90). Significantly greater expression levels of LAIR-1 were obtained from cancer tissue (Mean?±?SD?=?5.722?±?2.145) than that in adjacent tumor tissue (4.141?±?1.486). In addition, LAIR-1 expression was found to be significantly correlated with pathological grade of HCC, T stage, and age. Expression levels of LAIR-1 were related with worse overall survival rates of HCC patients, especially in HCC patients with hepatic cirrhosis.Conclusion
Results of this study show that LAIR-1 is expressed in HCC tissues and that high levels of LAIR-1 expression are associated with the poor cancer differentiation. In addition, overexpression of LAIR-1 was significantly associated with worse overall survival in the patients with HCC. These data suggest that LAIR-1 may be an independent predictor for clinical outcomes in patients with HCC. 相似文献2.

树突状细胞体外诱导高效而特异的抗结肠癌免疫 总被引:1,自引:0,他引:1
为达到以结肠癌患者外周血树突状细胞(DC)在体外诱导抗结肠癌免疫反应的目的,以结肠癌细胞系LOVO肿瘤细胞的肿瘤抗原粗提物激活并经GM-CSF及IL-4联合刺激的结肠癌患者外周血树突状细胞(DC)体外能够诱导自体混合T淋巴细胞增殖、分化为CTL,该CTL及其上清液对LOVO肿瘤细胞均有强大的杀伤力,而对HepG2肿瘤,该CTL细胞及HOS-8603肿瘤细胞仅有微弱的细胞毒作用。结果表明结肠癌患者外周血DC体外能够诱导高效而特异抗结肠癌免疫反应。提示DC作为一新概念上的肿瘤疫苗可能在肿瘤治疗及预防中发挥重要作用 相似文献

BackgroundPleural effusion is observed in a subset of patients with acute pulmonary embolism (APE) and may be linked to clinical outcome, but findings from previous studies have been inconsistent. This study aimed to investigate the prevalence and clinical significance of pleural effusion in Chinese patients with APE.MethodsClinical data from hospitalized patients with APE were retrospectively collected and the prevalence of pleural effusion was determined. The relationship between the presence of pleural effusion and clinical outcome of APE was analyzed by Cox proportional hazards regression and Kaplan-Meier survival analysis.ResultsThe study enrolled 635 patients with APE. The prevalence of pleural effusion was 57.01% (362/635). Patients with pleural effusion had significantly higher in-hospital mortality (9.9% vs. 4.8%, P<0.05) and longer length of hospital stay (LOS) (19.99 vs. 15.31 days, P<0.05) than whose without pleural effusion. However, pleural effusion was not an independent risk factor for in-hospital mortality in patients with APE by multivariate Cox proportional hazards regression analysis [hazard ratio (HR) =1.70, 95% confidence interval (CI): 0.73–3.92, P=0.216] and Kaplan–Meier survival analysis (P=0.174).ConclusionsPleural effusion is a frequent occurrence in patients with APE and therefore merits greater attention from clinicians; however, it is not an independent risk factor for in-hospital mortality. 相似文献

The aim of this study was to investigate the clinical efficiency of chemotherapy for the treatment of human alveolar echinococcosis (AE). Twenty-four patients who suffered from late-stage AE were enrolled in this study. The classification of the disease stages was performed according to the PNM (parasite lesion, neighboring organ invasion, metastases) classification system established by the World Health Organization Informal Working Group on Echinococcosis and classification standards. Radical surgery (n?=?3), palliative surgery plus chemotherapy (n?=?11), and sole chemotherapy (n?=?10) were given, respectively. For those with AE metastasis with spleen and kidney, radical surgery was effective for the treatment. However, the treatment efficiency for those with AE metastasis to bone tissues was unfavorable. Significant improvement was noted in those with cerebral lesions after chemotherapy. Stable health conditions were observed in those with pulmonary lesions after chemotherapy. For those with liver lesion, long stable health conditions were noted after chemotherapy. However, surgical interventions were needed as the occurrence of bile duct complications. With regards to the other lesions, radical surgeries were recommended. Satisfactory treatment outcomes were obtained in those with AE after chemotherapy. 相似文献
