Association of Bisphenol A Exposure With Hypertension and Early Macrovascular Diseases in Chinese Adults: A Cross-Sectional Study.
Bisphenol A (BPA) is an environmental endocrine disruptor that has been associated with cardiovascular outcomes in previous observational studies. We aimed to examine the relationships of urinary BPA levels with hypertension and early macrovascular diseases. This is a cross-sectional study. ⋯ The negative associations of BPA with hypertension, elevated CIMT, and arterial stiffness were consistent by age and sex stratifications, and were stronger among participants ≥60 versus <60 years of age, and among women than men. In contrast with previous investigations, our study suggests negative associations of BPA exposure with hypertension and early macrovascular diseases among middle-aged and elderly Chinese. Future investigations are needed to draw more definite conclusions and generalize to other populations.

Observational Study
Risk Factors, Coronary Severity, Outcome and ABO Blood Group: A Large Chinese Han Cohort Study.
ABO blood type locus has been reported to have ethnic difference and to be a pivotal genetic determinant of cardiovascular risk, whereas few prospective data regarding the impact on cardiovascular outcomes are available in a large cohort of patients with angiography-proven coronary artery disease, especially from the Chinese population. The objective of this study was to assess the prognostic role of blood type in future cardiovascular events (CVEs) in Chinese Han patients undergoing coronary angiography. The population of this prospective cohort study consisted of 3823 eligible patients, and followed annually to capture all CVEs. ⋯ The log-rank test revealed that there was a significant difference between non-O and O blood groups in event-free survival analysis (P = 0.026). In particular, the Cox proportional hazards models revealed that non-O blood type was associated with increased CVEs risk [hazard ratio (95% confidence interval) 1.320 (1.033-1.685)], even after adjusting for potential confounders [adjusted hazard ratio (95% confidence interval) non-O: 1.289 (1.003-1.656); A: 1.083 (0.797-1.472); B: 1.481 (1.122-1.955); AB: 1.249 (0.852-1.831), respectively]. Non-O blood type is associated with future CVEs in Chinese Han patients undergoing coronary angiography.

Observational Study
Prognostic Value and Grading of MRI-Based T Category in Patients With Nasopharyngeal Carcinoma Without Lymph Node Metastasis Undergoing Intensity-Modulated Radiation Therapy.
We investigated the prognostic value and gradation of the T category in N0 nasopharyngeal carcinoma (NPC) patients undergoing magnetic resonance imaging (MRI) and intensity-modulated radiotherapy (IMRT). A total of 749 patients were retrospectively reviewed, and a total of 181 N0 NPC patients were included in this retrospective study. All patients were restaged according to the 7th edition of the American Joint Committee on Cancer staging system. ⋯ The 5-year OS, PFS, and LRFS rates of group 3 differed significantly from those of groups 1 and 2, and a significant difference was observed in the DMFS rate only between groups 3 and 1. In Cox's proportional hazard analysis, the 3-grade T category was an independent prognostic factor for OS (P = 0.002), PFS (P < 0.001), and LRFS (P = 0.002). The 3-grade T category, using MRI according to the site of invasion, has prognostic value for the outcome of IMRT treatment in N0 NPC, and could aid in developing individualized treatment strategies.

CD147 is an important molecule in the inflammation and proteolysis process. This molecule crucially contributes to the initial and progression of atherosclerotic lesions. A single nucleotide polymorphism in CD147 gene, the rs8259 T/A in the 3'-untranslated region, is responsible for its expression in various cells. ⋯ Linear regression analysis showed that genotypes and disease conditions contributed 49% to the change of the plasma CD147 level. These results suggested that the single nucleotide polymorphism of CD147 gene rs8259 T/A was associated with ACS susceptibility. Allele T gene may decrease the relative risk of suffering from ACS through downregulation of CD147 expression.

Comparative Study
One-Year Mortality after Traumatic Brain Injury in Liver Cirrhosis Patients--A Ten-Year Population-Based Study.
This study investigated the 1-year mortality of patients who underwent brain surgery following traumatic brain injury (TBI) who also had alcoholic and/or nonalcoholic liver cirrhosis (LC) using a nationwide database in Taiwan. A longitudinal cohort study matched by propensity score with age, gender, length of ICU stay, HTN, DM, MI, stroke, HF, renal diseases, and year of TBI diagnosis in TBI patients with alcoholic and/or nonalcoholic LC and TBI patients without LC was conducted using the National Health Insurance Research Database in Taiwan between January 1997 and December 2007. The main outcome studied was 1-year mortality. ⋯ The main findings were (1) TBI patients with LC had a higher 1-year mortality (52.18% vs 30.61%) and a 1.75-fold increased risk of mortality (95% CI 1.61-1.90) compared with non-LC TBI patients, (2) renal diseases and HF are risk factors, but hypertension could be a protective factor in cirrhotic TBI patients, and (3) TBI patients with non-alcoholic LC and the coexistence of alcoholic and nonalcoholic LC had higher 1-year mortality compared with TBI patients with alcoholic cirrhosis. This study showed that patients with LC who have undergone brain surgery might have higher risk of 1-year mortality than those without LC. In addition, nonalcoholic and the coexistence of alcoholic and nonalcoholic LC show higher 1-year mortality risk than alcoholic in TBI patients with LC, especially in those with comorbidities of hypertension, diabetes mellitus, and stroke.
