Dyslipidemia is one of the most important independent modifiable risk factors for cardiovascular diseases. The objective of this study was to determine the prevalence and risk factors for dyslipidemia in Shenzhen, a special economic zone and large metropolitan area neighboring Hong Kong. A cross-sectional survey of 1,995 adults with a mean age of 46.56(More)
AIM To assess the effectiveness of immunosuppressants in the prophylaxis of corneal allograft rejection after high-risk keratoplasty and normal-risk keratoplasty. METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CNKI, VIP and reference lists of articles. Date of most recent search: 18 June, 2011. All(More)
Partial Differential Equations (PDEs) have become an important tool in image processing and analysis. A PDE mode for image zooming is introduced in this paper. This model exploits a higher order nonlinear partial differential equation. The resulted nonlinear equation is solved by an explicit finite difference schemes. Numerical results on real digital(More)
OBJECTIVE To study the mechanism of the effects of microwave on learning and memory. METHOD Long-term potentiation (LTP) of hippocampus induced potential and lipofuscin content in rat brain were studied. After irradiated by a 2450 MHz microwave, rats hippocampus induced potential in vivo was recorded and lipofuscin content in the brain was measured by(More)
We apply the dual algorithm of Chambolle for the minimization of the LLT model. A convergence theorem is given for the proposed algorithm. The algorithm overcomes the numerical difficulties related to the non-differentiability of the LLT model. The dual algorithm is faster than the original gradient descent algorithm. Numerical experiments are supplied to(More)
OBJECTIVE To study the changes of expression and secretion of some growth factors and ERK1/2 activation in cardiac fibroblasts under clinorotation conditions. METHOD Primary cultured neonatal rat cardiac fibroblasts were clinorotated to simulate weightlessness. The bFGF and TGF(beta)1 expressions in the cells and Ang II concentration in the medium were(More)
BACKGROUND Depression and anxiety among general hospital patients are common and under-recognized in China. This study aimed toward developing a short questionnaire for screening depression and anxiety in non-psychiatric clinical settings, and to test its reliability and validity. METHODS The item pool which included 35 questions about emotional distress(More)
OBJECTIVE To study the effect of microwave irradiation on hippocampus cell. METHOD Changes of ATPase activity and voltage dependent ion channel of hippocampus cell membrane were observed in mice exposed to 2 450 MHz microwave irradiation of 10 mW/cm2 from a physical therapy machine. Histochemical method and patch clamp method were used to determine the(More)
In this paper, combining the two existing waveletbased multi-scale variation (WBMV) models, wavelet-based multi-scale fourth-order partial differential equation (WBMF) and wavelet-based multi-scale total variation (WBMTV), we propose the wavelet-based multi-scale combination (WBMC) model, which overcome the defects of them. Furthermore, an image(More)
