Simultaneously, the relationship between Popdc3 expression and the survival of the patients was retrospectively analyzed.RESULTS： Popdc3 was detected in 72 （85.71%） of 84 human nontumor mucosa. High expression of Popdc3protein was detected in 78 （25.49%） of 306 human gastric cancer cases, and low expression was detected in 228 （74.51%）. Low expression of Popdc3 correlated with depth of invasion （P 〈 0.0001）, regional lymph nodes （P 〈 0.0001） and distant metastasis （P =0.02）, and tumor, nodes, metastasis （TNM） stages （P 〈 0.0001）. On multivariate analysis, only the patient＇s gender, regional lymph node metastasis, distant metastasis, TNM stages, and the expression of Popdc3 were independent prognostic factors in patients with gastric cancer. The Kaplan-Meier plot showed that low Popdc3 expression had a much more significant effect on the survival of those patients with early-stage tumors X^2 = 104.741, P 〈 0.0001）, with a 〉 51.9% reduction in the three-year survival compared with high Popdc3 expression. In late stages, the difference was also significant X^2 = 5.930, P = 0.015）, with a 32.6% reduction in the three-year survival.CONCLUSION： Reduced expression of Popdc3 may play a significant role in the carcinogenesis and progression of gastric cancer. Popdc3 may be an independent prognostic factor.展开更多

Methods and results Between 2007 and 2011 all consecutive patients with diagnosed with iCM at EMB were retrospectively analyzed. The combined primary endpoint （EP） （1E°P） was cardiac death, aborted sudden cardiac death/appropriate implantable cardioverter defibrillator （ICD） shock, progressive heart failure requiring left venWicular assist device （LVAD） implantation and heart transplantation. 503 patients （mean age 58 ° 12 years, 73% male） were available for analysis. Genomes of cardiotrophic viruses were detected in 396 patients （79%） and immuno-histochemical signs of inflammation were present in 223 individuals （44%）. After 3.6 ° 2.4 years of follow-up, cardiac mortality was 3.0% （n = 14） and a total of 8.6% （n = 40） reached the primary endpoint. Independent predictors for the 1 °EP were： age 〉 50 years, presence and duration （〈 28 days） of symptomatic heart failure. A risk stratification approach based on the results of the multivariate analysis demonstrated that absence of signs and/or symptoms of congestive heart failure in younger （〈 50 years） patients with longer （〉 28 days） duration of disease appear to have an excellent prognosis with 100% survival and no events during follow-up The presence of all above mentioned independent risk factors results in an 1°EP occurrence of 35.9%. Conclusions Symptoms of heart fail- ure, short duration of disease, and older age are indicators of poor outcome in patients with iCM.展开更多
