A cross-sectional survey on the prevalence of anxiety symptoms in Chinese patients with premature ventricular contractions without structural heart disease.
Anxiety appears to be more common in patients with coronary artery disease (CHD) than in the general population, and anxiety symptoms may precede onset of CHD and play an important role in development of CHD. Little is known about the prevalence of anxiety symptoms in Chinese patients with premature ventricular contractions (PVCs). Our objective was to study anxiety symptoms and potential risk factors in a Chinese population with PVCs but without structural heart disease. ⋯ In the Chinese population, anxiety symptoms in subjects with PVCs were frequent. Education level, ethnic minorities, dwelling place, age, PVC count/24 hours, and social support were independent risk factors for anxiety symptoms. Further research on the relationship between PVCs and anxiety symptoms in China is necessary.

Does vitamin D affect disease severity in patients with ankylosing spondylitis?
Vitamin D has been found to have a role in the function of the immune system. There have been a lot of studies investigating a relation between vitamin D and disease activity in ankylosing spondylitis (AS). However, there have not been any studies arranging AS in groups according to vitamin D levels and determining any differences among these patients in terms of disease activity, functional status, quality of life, and other clinical parameters. The aim of this study is to compare 25-hydroxy-vitamin D3 (25(OH)D3) levels in AS patients with those in normal healthy subjects and to determine the relationship between 25(OH)D3 levels and AS disease activity, functional status, and quality of life. ⋯ The plasma 25(OH)D3 levels may decrease in AS patients and this may negatively affect disease activity, functional status and quality of life.

Value of frozen section examination in diagnosis and treatment of high-grade cervical intraepithelial neoplasia.
Invasive cancer of the cervix is considered a preventable disease because it has a long pre-invasive state, cervical cytology screening programs are currently available, and treatment of pre-invasive lesions is effective. We tested the accuracy of frozen section examination (FSE) of cone specimens to identify the endocervical margin and rule out invasion in patients with high-grade cervical intraepithelial neoplasia (CIN). ⋯ FSE is a rapid and reliable method for evaluating CKC specimens. It can identify frank invasion, permit adequate treatment in a one-stage procedure, and reliably detect clear resection margins. Since discrepancies do exist and may result in inappropriate treatment, further research is required to decrease these discrepancies and avoid missing even one case.

Pilon fractures: a new classification and therapeutic strategies.
Operative decision-making of Pilon fractures are of great challenges until now. The aim of this study was to investigate the guidance of the four-column theory in decision-making therapeutic strategies for Pilon fractures and its result. ⋯ As a simple and comprehensive classification, the four-column classification can contribute to reasonable operation decision-making and good prognosis of Pilon fracture.
