Synthesis of selenium-containing Artemisia sphaerocephala polysaccharides: Solution conformation and anti-tumor activities in vitro.

It has been reported in our previous work that selenized Artemisia sphaerocephala polysaccharides (SeASPs) with the Se content range of 168-1703μg/g were synthesized by using Na2SeO3/HNO3/BaCl2 system. In the present work, the solution property of SeASP was studied by using size exclusion chromatography combined with multi angle laser light scattering (SEC-MALLS). A decrease in df values indicated that SeASPs with different conformational features that were highly dependent on MW.

Prevalence and risk factors of prolonged QTc interval among Chinese patients with type 2 diabetes.

Objectives: The aim of this study was to evaluate the prevalence and the risk factors of prolonged QTc interval among Chinese patients with type 2 diabetes.

Methods: The retrospective study included 3156 outpatients from the Diabetes Centre, the 306th Hospital of PLA, during the period from September 2003 to June 2010. QT interval was measured manually in the 12-lead conventional electrocardiogram.

Incidence, risk factors for amputation among patients with diabetic foot ulcer in a Chinese tertiary hospital.

Objectives: The aim of this study was to evaluate the incidence of amputation among patients with diabetic foot ulcer (DFU) and risk factors for amputations.

Methods: This is a retrospective study of 450 inpatients treated in a multi-discipline based diabetic centre, 306th Hospital of PLA during the period of January 2000-September 2009. Hospital admission and discharge information including patient profile, grade of DFU, co-morbidities and complications, laboratory data and final outcome were collected.
