Observational Study
Clinical Characteristics and Treatment of Extremity Chronic Osteomyelitis in Southern China: A Retrospective Analysis of 394 Consecutive Patients.
Although extremity chronic osteomyelitis is common in China, updated data were still limited regarding its characterizations. The present study aimed to review clinical features of extremity chronic osteomyelitis in Southern China. A retrospective analysis was conducted in the patients who had sought medical attention from January 2010 to April 2015 for extremity chronic osteomyelitis in Nanfang Hospital in Southern China. ⋯ S. aureus was the most frequent pathogenic organism. Preoperative elevated levels of serum IL-6, TNF-α, and ESR may be helpful diagnostic indicators of the disease. Most patients achieved a favorable clinical efficacy after appropriate treatment.

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 Clinical Trial
A Comparison of Transthroracic Echocardiograpy and Transcranial Doppler With Contrast Agent for Detection of Patent Foramen Ovale With or Without the Valsalva Maneuver.
Patent foramen ovale (PFO) is a remnant of the fetal circulation exist in 20% of the general population. The purpose of our study was to compare of transthoracic echocardiography (TTE) and contrast-transcranial Doppler sonography (c-TCD) in the diagnosis and quantification of PFO with or without the Valsalva maneuver (VM). We studied 106 patients with a high clinical suspicion for PFO prospectively. ⋯ Both c-TCD and TTE should used as initial screening tool for PFO. VM increases the size of shunt. VM resulted in detection of more RLS both in c-TCD and TTE tests.

Observational Study
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.
