A highly sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for the determination of forsythiaside in rat plasma using epicatechin as internal standard. The analytes were extracted by solid-phase extraction and chromatographied on a C(18) column eluted with a gradient mobile phase of acetonitrile and water both(More)
Image interpolation is widely used for the field of medical image processing. In this paper, interpolation methods are divided into three groups: filter interpolation, ordinary interpolation and general partial volume interpolation. Some commonly-used filter methods for image interpolation are pioneered, but the interpolation effects need to be further(More)
HHT (Hilbert transform) and wavelet transform are both signal processing methods. This paper is based on HHT and wavelet transform to detect R peak. Firstly using wavelet transform to de-noise, then we are focus on using the empirical mode decomposition (EMD) to electrocardiogram (ECG) which can be decomposed into a limited number of IMF (intrinsic mode(More)
OBJECTIVE To explore the relationship between physical and biological effects of alternating magnetic field and study the influence of the magnetic field on the reproductive function of murine testes. METHODS Thirty ICR mice were randomized into 5 groups: normal control, X-ray radiation, weak magnetic field (1000 Hz), 1 h strong magnetic field and 2 h(More)
Medical image registration plays a crucial role in clinical diagnosis, treatment, quality assurance, evaluation of curative efficacy and so on. In this paper, by computing the medical image moments, the centroid is obtained, and according to the rotational invariance of the singular values of the matrix of the medical image coordinates, the rotation angles(More)
BACKGROUND & OBJECTIVE Many nasopharyngeal carcinoma (NPC) patients could survive for a long time after radiotherapy. But the complications of radiotherapy, such as trismus, severely influence the quality of life of NPC patients. This study was to observe the effect of early rehabilitation training on radiation-induced trismus of NPC patients. METHODS A(More)
