Objective To observe the correlation between 1-hour postload plasma glucose and carotid intima-media thickness (IMT) in elderly male patients with hypertension.Methods One hundred and twenty six elderly male patients with hypertension were enrolled and divided into four groups: normal glucose tolerance with normal 1 h plasma glucose (1 hPG) group (low-NGT, n=42); normal glucose tolerance with high lh plasma glucose group (high-NGT, n=23);impaired glucose tolerance group (IGT, n=27) and diabetic group (n=84). The differences of blood pressure, blood glucose, blood lipid and intimia-media thickness among groups were analyzed.Results OGTT 1 hPG in high-NGT group was similar with IGT group[(12.0±1.1)mmol/L vs. (11.1±1.8)mrnol/L, P>0. 053 ,but significantly higher than that in Iow-NGT group ((12.0±1.1)mmol/L vs. (9. 1±1.4) mmol/L, P<0.01]. The value of IMT was gradually increased in four groups (P<0.05) and it was (1.02±0. 12) mm in high-NGT group. OGTT 1 hPG was the independent risk factor for IMT(P< 0.01).Conclusions OC-TT 1h plasma glucose is associated with atherosclerosis in elderly male hypertensive people.

Background:The TNM staging system is far from perfect in predicting the survival of individual cancer patients because only the gross anatomy is considered. The survival rates of the patients who have the same TNM stage disease vary across a wide spectrum. This study aimed to develop a nomogram that incorporates other clinicopatho-logic factors for predicting the overall survival (OS) of non-metastatic nasopharyngeal carcinoma (NPC) patients after curative treatments. Methods:We retrospectively collected the clinical data of 1520 NPC patients who were diagnosed histologically between November 2000 and September 2003. The clinical data of a separate cohort of 464 patients who received intensity-modulated radiation therapy (IMRT) between 2001 and 2010 were also retrieved to examine the extensibil-ity of the model. Cox regression analysis was used to identify the prognostic factors for building the nomogram. The predictive accuracy and discriminative ability were measured using the concordance index (c-index). Results:We identiifed and incorporated 12 independent clinical factors into the nomogram. The calibration curves showed that the prediction of OS was in good agreement with the actual observation in the internal validation set and IMRT cohort. The c-index of the nomogram was statistically higher than that of the 7th edition TNM staging sys-tem for predicting the survival in both the primary cohort (0.69 vs. 0.62) and the IMRT cohort (0.67 vs. 0.63). Conclusion:We developed and validated a novel nomogram that outperformed the TNM staging system in predict-ing the OS of non-metastatic NPC patients who underwent curative therapy.
