Gastric carcinogenesis is one of the most commonly occurring malignant neoplasms in China, and early diagnosis and treatment are crucial to improving the quality of life and reducing mortality rates for patients with gastric cancer. Serum-based detection methods allow for a standardized and non-invasive approach to monitoring progression of gastric cancer. We therefore summarize four serum-based biomarkers (E-cadherin, Runx3, hGC-1 and 3 subtypes of VEGF family) for gastric cancer, categorized into groups of genes and proteins, and evaluate their individual values in detecting gastric cancer, surveillance and evaluating prognosis of patients with gastric cancer.

Leukocyte telomere length (LTL) is a predictor of aging and a number of age-related diseases. We performed genome-wide association studies of mean LTL in 2632 individuals,with a two-stage replication in 3917 individuals from Chinese populations. To further validate our findings, we get the results of 696 samples from a cohort of European ancestry. We identified two loci associated with LTL that map in telomerase reverse transcriptase (TERT; rs2736100, P = 1.93x10-5) on chromosome 5p15.33 and near keratin 80 (KRT80; rs17653722, P=6.96x10-6) on 12q13.13. In Chinese population each C allele of rs2736100 and T allele of rs17653722 was associated with a longer mean telomere length of 0.026 and 0.059 T/S, respectively, equivalent to about 3 and 7 years of average age-related telomere attrition. Our findings provide new insights into telomere regulatory mechanism and even pathogenesis of age-related diseases. © 2014 Liu et al. Source

The aim of this study was to investigate the associations of matrix metalloprotease-1 (MMP-1) and its receptor protease-activated receptor-1 (PAR-1) coexpression with the clinicopathological characteristics and prognosis of patients with prostate cancer (PCa). Immunohistochemistry was performed to detect the expression changes of MMP-1 and PAR-1 proteins in 180 pairs of human PCa tissues and matched non-cancerous prostate tissues. Then, the associations of combined MMP-1 and PAR-1 expression with selected clinicopathological characteristics and patient prognosis were evaluated. Both MMP-1 and PAR-1 proteins were positively localized in cytoplasmof tumor cells in PCa tissues. Compared with non-cancerous prostate tissues, MMP-1 (PCa vs. Normal: 4.15 ± 1.28 vs. 2.37 ± 1.16, P < 0.001) and PAR-1 (PCa vs. Normal: 3.71 ± 1.21 vs. 1.55 ± 1.12, P < 0.001) protein expressionwere both significantly upregulated. More interestingly, the expression levels of MMP-1 in PCa tissues were positively correlated with those of PAR-1 significantly (Spearman correlation coefficient r = 0.88, P < 0.001). In addition, the coexpression of MMP-1 and PAR-1 (MMP-1-high/PAR-1-high) in PCa tissues was significantly associated with the higher Gleason score (P < 0.001), the presence of metastasis (P < 0.001) and the advanced pathological stage (P = 0.009). Furthermore, both univariate and multivariate analyses showed that MMP-1-high/PAR-1-high expression was an independent predictor for both unfavorable overall survival and biochemical recurrence-free survival. These findings confirmed for the first time that the upregulation of MMP-1 protein combined with the overexpression of PAR-1 protein may contribute to the malignant progression of PCa. More importantly, MMP-1/PAR-1 axis may be a negative prognostic factor for patients with PCa. © Springer Science+Business Media 2014. Source

Purpose: To assess the short-term day-to-day reproducibility of 24-hour intraocular pressure (IOP) curves in various respects in untreated primary open-angle glaucoma (POAG) and ocularhypertension (OHT) patients. Methods: 47 subjects with POAG and 34 subjects with OHT underwent IOP measurements every 2 hours in both eyes for consecutive 48 hours by a non-contact tonometer (NCT). IOP valuesat each time point were recorded. Mean IOP, peak IOP, time difference of peak IOP between two days and IOP fluctuation were also calculated. Intraclass correlation coefficients (ICCs) and Bland-Altman plots were used to evaluate reproducibility. Results: ICCs of the entire IOP values for a complete 24-hour curve were 0.577 and 0.561 in POAG and OHT patients, respectively. ICCs of IOP values at different time points ranged from0.384 (10am) to 0.686 (4am) in POAG patients and from 0.347 (6am) to 0.760 (4am) in OHT patients. ICCs of mean IOP, peak IOP and IOP fluctuation were respectively 0.832, 0.704, 0.367 in POAG patients and 0.867, 0.816 0.633 in OHT patients. Only 37.23%and 35.29%of the peak IOP time points appeared within the time difference of 2 hours in POAGand OHT patients, respectively, while 53.19%and 48.53%appeared within 4 hours in POAG and OHT patients, respectively. Conclusion: A 24-hour IOP curve in a single day is not highly reproducible in short-term and has limiteduse for evaluating individual IOP condition. Mean IOP and peak IOP for a 24-hour IOP curve are useful parameters in clinical follow-up, while IOP value at a certain time point, IOP fluctuation and peak IOP time point should be interpreted with caution. © 2015 Xu et al.This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.
