Preoperative surgical planning for intracranial meningioma resection by virtual reality.
The Dextroscope system by Volume Interactions (Singapore) had been applied to minimally invasive neurosurgery in many units. This system enables the neurosurgeon to interact intuitively with the three-dimensional graphics in a direct manner resembling the way one communicates with the real objects. In the paper, we explored its values in pre-operation surgical planning for intracranial meningiomas resection. ⋯ According to the virtual reality planning, neurosurgeons could get more anatomic information about meningioma and its surrounding structures, especially important vessels, and choose the best approach for tumor resection, which would lead to better prognosis for patients.

White blood cells contribute to patient-specific warfarin dose for Han Chinese.
Warfarin is the most commonly prescribed anticoagulant worldwide. Factors which influence warfarin's inter-individual requirements including age, weight, and genetic factors explained about 50% of dose variance, and unidentified factors still remain. The aim of this study was to explore whether white blood cell count affects warfarin dose requirements. ⋯ White blood cell count has a small but significant contribution to warfarin dose requirements in Han Chinese.

HIV prevalence and influencing factors analysis of sentinel surveillance among men who have sex with men in China, 2003 - 2011.
Men who have sex with men (MSM) have been impacted by HIV and now as an important driver of the HIV/AIDS epidemic in China. This study collected HIV sentinel surveillance system data on the MSM population to describe the characteristics and trends of the HIV epidemic among MSM in China from 2003 to 2011. ⋯ HIV prevalence in MSM populations is rapidly and widely distributed. MSM who are in heterosexual marriages may be a bridge group transmitting HIV to their heterosexual partners. The risky sexual behavior among MSM will remain a serious and important driver of China's AIDS epidemic over the next period of time. Intervention need to be strengthened, as does the effective implementation of measures to control AIDS and prevent it from spreading further.

Differentiation of white and red thrombus with magnetic resonance imaging: a phantom study.
An early identification of the composition of arterial thrombus may have diagnostic, therapeutic, and prognostic implications. The variation of magnetic resonance (MR) signal intensity between white and red thrombi, especially in the susceptibility sensitive MR sequence, remains unknown. Our research was to evaluate the feasibility of MRI in differentiating of white and red thrombi with a phantom study. ⋯ Differentiation of white and red thrombi with conventional MR sequence is unreliable, because both kinds of thrombi do not possess unique signal intensity features in these sequences. Red thrombus may or may not show hypointensity in the susceptibility sensitive MR sequences, depending on its size and time course.

Clinical TrialSteady-state pharmacokinetics of zidovudine in Chinese HIV-infected patients.
The pharmacokinetics of zidovudine (AZT) are possibly influenced by weight, age, sex, liver and renal functions, severity of disease, and ethnicity. Currently, little information is available on the steady-state pharmacokinetics of AZT in Chinese HIV-infected patients. The current study aimed to characterize the steady-state pharmacokinetics of AZT in a Chinese set-up. ⋯ The present study provides valuable information for the clinical practice of AZT-based highly active antiretroviral therapy in a Chinese set-up.
