The present study investigated the association between the presence of periodontitis and aortic calcification (AC) risk among Chinese adults. A total of 6059 individuals who underwent regular health check-ups and received a diagnosis of periodontitis between 2009 and 2016 were included. The outcome was AC, assessed by a chest low-dose spiral CT scan. Cox proportional hazards regression analysis was used to assess the association between periodontitis and AC risk after adjusting for several confounders. After a median follow-up period of 2.3 years (interquartile range: 1.03–4.97 years), 843 cases of AC were identified, with 532 (12.13%) and 311 (18.59%) patients in the non-periodontitis group and periodontitis group, respectively. Multivariate analyses demonstrated that, compared with those without periodontitis, the hazard ratio and 95% confidence interval for AC risk in participants with periodontitis was 1.18 (1.02–1.36) (P =.025) in the fully adjusted model. Stratified analyses showed that the positive relationship between periodontitis and AC was more evident in males and participants <65 years of age (pinteraction =.005 and.004, respectively). Our results show that the presence of periodontitis was positively associated with AC among Chinese adults, especially among males and younger participants. [ABSTRACT FROM AUTHOR]

Trans-resveratrol and resveratrol glucoside are natural phenolic compounds existed in a wide variety of plant species, which are extensively consumed in many countries. The existing studies excessively focused on grapes and their products, and little about daily vegetable foods. Actually, in much more countries, vegetable foods are residents' principal food and nutrient origins. This study was to investigate the levels of trans-resveratrol and trans-piceid in daily vegetable foods of China using high-performance liquid chromatography (HPLC) method with fluorescence detection (FLD). Trans-piceid was the major form existing in most vegetable foods, and most of the samples contained higher trans-piceid than trans-resveratrol. The contents of trans-resveratrol and trans-piceid in different varieties and regions were different. Moreover, peculiar vegetable foods to some region were also one of the most important sources of trans-resveratrol and trans-piceid. Therefore, vegetable foods were other significant sources of trans-resveratrol and trans-piceid except the foods published. [ABSTRACT FROM AUTHOR]

Objective: To investigate the variation of common allergens in patients with allergic rhinitis in recent 4 years in Tianjin First Center Hospital., Methods: The medical records of skin prick test on 3292 patients with allergic rhinitis between 2009 and 2012 were restrospectively analyzed. The changing trend of various allergens in 4 years and distribution differences were compared. The differences of the top 5 allergens in under age group, adult group and different gender group were further analyzed by SPSS 19.0 software., Results: The positive rate of dermatophagoides farinae was increasing year by year, from 45.1% in 2009 to 66.3% in 2012, and the positive rate of dermatophagoides pteronyssinus increased from 42.0% in 2009 to 58.6% in 2012, the difference was statistically significant (χ(2) value was 68.70, 41.55, all P < 0.01). The positive rate of dermatophagoides farinae and dermatophagoides pteronyssinus in adult group and male group showed significant upward trend year by year (χ(2) value was 75.85, 69.93, 274.25, 42.62, all P < 0.01), but not in adult group and female group. The positive rate of quinoa, mugwort and humulus scandens decreased year by year between 2009 and 2011(χ(2) value was 22.08, 11.64, 203.19, all P < 0.01), but increased again in 2012(χ(2) value was 21.55, 29.38, 12.40, all P < 0.01)., Conclusions: There is a tendency of change of allergens in patients with AR. This phenominon may be helpful for doctors to choose the type of skin prick liquid.
