Objective To study the relationship among the area of transverse section of radial artery, the major axis length of the ellipse with same centroid as transverse section, the maximum centroid displacement in the direction parallel with skin surface in a cardiac cycle and width of pulse tracing. Methods ECG, pressure phygmograms and ultrasound images of transverse section of radial artery of 40 patients with different width of pulse tracing and 20 healthy persons were collected synchronously with a new-type sphymograph. On the basis of images analysis with MATLAB 7.0.1, image characteristics of transverse section of radial artery and centroid motion locus of pulse tracings with different width in a cardiac cycle were observed and analyzed. Results Between pulse tracings with different width, there were significant differences in the area of transverse section of radial artery, the major axis length of the ellipse with same centroid as transverse section and the maximum centroid displacement in the direction parallel with skin surface in a cardiac cycle. Conclusions The mean, maximum and minimum value of the area of transverse section and the major axis length of ellipse and the maximum centroid displacement can be used to discriminate width of pulse tracing.

Pulse shape and pulse force are difficult to detect in pulse taking study. But the application of visualized technology extends the space acquisition of pulse taking information, and it is possible to realize the objective detection of pulse shape and pulse force. Rational research thoughts and strategies could be informed by combining image information and other data, and it is a necessary method in implementing the objective detection of pulse.

Acupuncture was frequently used for alternative treatments in Parkinson's disease because of its safety,but there was an argument whether acupuncture improves motor symptoms or not.Besides,few electrophysiological studies were designed for acupuncture combined with Parkinson's disease Using the technique of paired transcranial pulse magnetic stimulation,we measured the excitability of corticocortical inhibitory circuits to investigate effects of scalp acupuncture from 9 patients with Parkinson's disease.Although patients didn't take any short-term benefit in motor symptoms through the treatment of scalp acupuncture,there was no any adverse event,and some electrophysical effects developed in patients.The enhanced corticocortical inhibition on motor cortex possibly developed at longer interstimulus intervals,and there was a relatively increase in later part of motor-related cortical potentials on the central part and right-side near vertex around over sensory cortex,but was not significant in early potentials.So a further long-term study is essential to ascertain the physical mechanism and clinical effects in scalp acupuncture.

This study was aimed to investigate short-term modulation mechanism of scalp acupuncture according to the experimentation of cortical excitability and motor-related cortical potentials in ten normal volunteers.Through scalp needle stimulation in specific theoretical areas related to underlying cerebral surfaces,scalp acupuncture can be used as an effective therapy by changes in relative cerebral function,which is the basic principle.According to the available neurophysiological data in our study,the modulation of scalp acupuncture displayed in late part of motor-related cortical potential noticed mainly in the motor and sensory cortexes,contralateral to the needle stimulate site.Also,acupuncture can develop inhibition at longer interstimulus intervals,in paired pulse magnetic stimulation,from the somatosensory input of contralateral sensory cortex via scalp needle stimulation.In our study,it might be difficult to produce more acupuncture inhibition.The maintaining of scalp needles subcutaneously without other management after achieving needling sensations cannot achieve the requested strength of the acupuncture stimulation.

Objective:To review literature reports of varieties of ADRs induced by mebendazole to provide a sci- entific foundation for clinical revaluation of mebendazole.Method:The related literatures in the internal and external medi- cine medical database in 1994-2004 were explored,and then both analysis and statistics were conducted with the methods of epidemiolngy and literature analysis.Result:ADRs induced by mebendazole could be involved in multiple organs.Most victims were children and the elderly.Their latent periods were determined by the types of ADRs,which had a variety of forms.Conclusion:Mebendazole was potentially unsafe.So we should strengthen our rational drug use and post-marketing revaluation of safety.

OBJECTIVE: This study was conducted to evaluate the percutaneous absorption of aconitine and mesaconitine in extracts of Radix Aconitum kusnezoffii. METHODS: The extracts of Radix Aconitum kusnezoffii were collected by using Franz diffusion cells after permeation through the skin of rats. Then rate constants of skin permeation of aconitine and mesaconitine were determined by high-performance liquid chromatography (HPLC). RESULTS: Under the condition that the concentrations of azone and propylene glycol were both 4%, the cumulative doses of skin permeation (Q) of mesaconitine and aconitine in the extracts of Radix Aconitum kusnezoffii (600 mg/ml) for 24 hours were 165.819 and 487.747 microg/cm(2) respectively, and their rate constants of skin permeation were 18.391 and 78.805 microg.cm(-2).h(-1) respectively. CONCLUSION: The aconitine and mesaconitine in the extracts of Radix Aconitum kusnezoffii can penetrate well through the skin of rats. Propylene glycol and azone can promote this penetration effects. The formula of skin permeation of mesaconitine and aconitine is in accordance with Higuchi equation and there is a linear relationship between Q and t(1/2).

Objective Base on the theory of traditional Chinese medicine (TCM), obtained human diagnostic information available for joint syndrome differentiation is integrated based on subjective and objective combined syndrome differentiation, in the form of data expression of TCM four diagnosis, forms multiple information fusion of open platform for TCM diagnosis and treatment, and provides some revelation for promoting the development of depression and treatment technology. Methods Totally 30 depression patients and 30 normal people were selected according to the inclusion criteria. TCM four diagnostic and auxiliary diagnosis instrument was used to collect information of four diagnosis, and the statistical software was used for the analysis on pulse diagnosis, and information features of digitalized tongue and listening diagnosis of patients in depression group and normal group were studied. Results Compared with depression group, pulse frequency, fluency, and heart rate of normal group were a bit higher than depression group, without statistical significance (P>0.05);There was statistical significance among pulse frequency, strength, tightness, and pulse wave velocity between the normal group and depression group (P<0.05). 30 patients had 6 depression syndrome types:heart-gallbladder qi deficiency (8 cases), phlegm-heat attacking internally (6 cases), fire excess from yin deficiency (6 cases), liver depression forming fire (6 cases), intense heart fire (3 cases), and heart-spleen deficiency (3 cases). Conclusion The results of differences in pulse diagram parameters were consistent with the theory of classical TCM pulse theory. The results of differences in pulse wave velocity conform to the modern medical research conclusion. TCM four diagnostic auxiliary diagnosis and treatment technology can realize the dynamic detection of depression patients with four diagnostic information, and establish diagnostic methods for depression based on digitalized four diagnostic auxiliary diagnosis.
