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.

Objective To study the efficacy of external dissection & internal ligation for beating mixed hemorrhoids, and compare with Milligan-Morgan. Methods One hundred and twenty-six patients with mixed hemorrhoids were divided into two groups: treatment group(66 cases)and controlled group(60cases).In treatment group used external dissection & internal ligation for treating mixed hemorrhoids, but in eontrolled group used Milligan-Morgan. Then the differences between both groups in healing time of wound surface, as well in the statuses of bleeding, pain, edema, anus stenosis, and anus overflow liquid were observed. Results Averaged healing time in treatment group was significantly shorter than that in controlled group, (8.2±2.6)days vs (17.4±3.8)days, P＜0.01.The anus stenosis and anus overflow liquid were significantly less in treatment group than those in controlled group, P＜0.01.Conclusion External dissection & internal ligation of hemorrhoids for treating mixed hemorrhoids decreases anal transitional zone(ATZ)disorganization, shorten healing time, and significantly decreases crissum scar,protectes anus function effectively.

Objective To investigate the correlation between serum levels of B cell activating factor (BAFF) and disease activity in the patients with dermatomyositis (DM).Methods Serum BAFF levels of 61 patients with DM and 25 matched healthy controls were measured by ELISA.The results of the two groups were compared using unpaired Mann-Whitney U test and the relevance was analyzed using Spearman correlation analysis.Results Serum levels of BAFF in DM patients were significantly higher compared to healthy controls [(274 7±264 6) pg/ml 与 (832±170) pg/ml,Z=-5.492,P＜0.01].A cross-sectional assessment revealed that serum BAFF levels were positively correlated with global disease activity (r=0.501,P＜0.001),muscle disease activity (r=0.303,P＜0.05),and cutaneous disease activity (r=0.467,P＜0.01).High serum BAFF levels were associated with increased incidence of interstitial lung disease (x2=17.238,P＜0.01).The longitudinal study showed modest correlations between serum BAFF levels and global disease activity (r=0.658,P＜0.01),muscle disease activity (r=0.307,P＜0.05),as well as cutaneous disease activity (r=0.565,P＜0.01).Conclusion Serum levels of BAFF correlate with disease activity in DM patients.The results of this study suggest that BAFF is a serological biomarker for DM disease activity.

Objective To evaluate sacral nerve stimulation (SNS) in the treatment of spastic pelvic floor syndrome (SPFS).Method In this study,36 patients of spastic pelvic floor syndrome who received SNS treatment from 2011.3 to 2011.12,were reviewed in terms of clinical curative effect,changes of anal pressure and defecography.Result After a course of SNS treatment,patients were followed up for 3 months,12 cases were cured,22 cases improved and 2 cases were ineffective,the total effective rate was 94.4％.The symptoms such as endless defecate feeling,difficulty in defecation,anal pain and anal obstruction feeling improved significantly (P ＜0.01 ).After the therapy,rectal anal reflex( RAR)threshold value volume rose,anal maximum contraction pressure (AMCP),anal rest perssure (ARP) decreased (P ＜ 0.01 ).While the anal longest contraction time (ALCT)and rectal rest pressure (RRP) did not change significantly (P ＞ 0.05 ).After treatment,when patient defecate the anorectal angle (ARA) increases,the puborectal muscle spasm notch (PMSN)attenuates (P ＜ 0.01 ).Conclusions SNS is effective and minimally invasive in treating spastic pelvic floor syndrome.

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.

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.

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.

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).

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.
