Chinese Journal of Integrated Traditional and Western Medicine 2010;30(1):26-29
OBJECTIVETo investigate the application of surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI) protein chip in diagnosis and Chinese medicie syndrome type researching of systemic lupus erythematosus (SLE).
METHODSEighteen female SLE patients of mild/moderate degree with yin-deficiency caused internal heat syndrome (YDHS) were enrolled in the treatment group, and 15 women healthy volunteers was set up as the control group. Using SELDI method, the pre-, mid- and post-treatment peripheral blood mononuclear cell (PBMC) protein fingerprint of them was created respectively, which was then managed to screen out the markers by using ZUCI-PDAS package for establishing a diagnosis model.
RESULTSStudy was completed in 15 cases of the treatment group with 2 cases dropped out and 1 case lost. Before treatment, 44 protein peaks in the treatment group were found significantly different to those in the control group (P<0.01), and the sensitivity and specificity of the created models, 10542 Da m/z and 2554 Da m/z, reached 100%. After a 12-week treatment, 30 peaks were found significantly different between the two groups (P<0.01), and the sensitivity of 3365, 7104, 3882 and 6796 Da m/z created peak models was 100%, its specificity being 93.33%. Comparing the 35 samples (pre-, mid- and post-treatment) got from the treatment group with the 15 samples from the control group, significant difference was found in 55 peaks (P<0.01), the sensitivity and specificity of the 7103, 3882, 7143 Da m/z created peak models was 100% and 91.43% respectively.
CONCLUSIONSignificant differences of PBMC protein expression patterns were found between SLE patients of YDHS and healthy persons at times of before, during and after treatment, suggesting that SELDI may be used as a new method to create the diagnosis model, and its application in effecter protein screening, activity scoring and Chinese medicine syndrome type researching are expectable and waiting for further study in depth.

OBJECTIVETo study the effect of Jingjielianqiao Decoction in promoting leg ulcer in rabbits.
METHODSNine adult male New Zealand albino rabbits with chronic leg ulcers were randomized into 3 groups, namely group A treated with Jingjielianqiao Decoction, group B with Shengjiyuhong Decoction, and group C with normal saline. Gross observation of the wounds was carried out regularly for evaluating the changes in the ulcerous area, depth and wound surface excretion. After 3 weeks of treatment, the tissues on the edge of the ulcer were sampled and prepared for routine pathological examination, electron microscopy and immunohistochemistry for vascular endothelial growth factor (VEGF) and CD34. The number of blood vessels and their areas were also recorded.
RESULTSThe wounds showed no significant differences between the 3 groups by gross observation during the treatment, but after completion of the 3-week treatment, routine pathological examination and electron microscopy revealed significant differences between the groups. Immunohistochemistry for VEGF and CD34 yielded comparable results between groups A and B (positive control), but showed significant differences between group C and the other two groups (P<0.01).
CONCLUSIONJingjielianqiao Decoction and Shengjiyuhong Decoction can obviously promote the healing of leg ulcer in rabbits.

OBJECTIVE: Visual search is an important attention process that precedes the information processing. Visual search also mediates the relationship between cognition function (attention) and social cognition (such as facial expression identification). However, the association between visual attention and social cognition in patients with schizophrenia remains unknown. The purposes of this study were to examine the differences in visual search performance and facial expression identification between patients with schizophrenia and normal controls, and to explore the relationship between visual search performance and facial expression identification in patients with schizophrenia. METHODS: Fourteen patients with schizophrenia (mean age=46.36+/-6.74) and 15 normal controls (mean age=40.87+/-9.33) participated this study. The visual search task, including feature search and conjunction search, and Japanese and Caucasian Facial Expression of Emotion were administered. RESULTS: Patients with schizophrenia had worse visual search performance both in feature search and conjunction search than normal controls, as well as had worse facial expression identification, especially in surprised and sadness. In addition, there were negative associations between visual search performance and facial expression identification in patients with schizophrenia, especially in surprised and sadness. However, this phenomenon was not showed in normal controls. CONCLUSION: Patients with schizophrenia who had visual search deficits had the impairment on facial expression identification. Increasing ability of visual search and facial expression identification may improve their social function and interpersonal relationship.

OBJECTIVETo analyze the differences in the immediate effect of acupuncture on cervical spondylosis of vertebral artery type among three factors: needling technique, acupoint selection and time of needle retaining so as to option the best therapeutic program.
METHODSThirty-two cases were observed and randomly divided into 8 groups, 4 cases in each one. The orthogonal design of three factors and two levels was adopted. There were needling technique (electroacupuncture, reinforcing and reducing method), acupoint selection [C4-C7 Jiaji (EX-B 2) and three needles of neck: Tianzhu (BL 10), Jingbailao (EX-LHN 15), Dazhu (BL 11)] and time of needle retaining (5 min, 15 min). L8 (2(7)) orthogonal design table was arranged in the trial. The changes in mean velocity (Vm) of vertebral artery (VA) and basilar artery (BA) were observed before and after acupuncture.
RESULTSThe immediate effect of VA-BA blood flow was the most significant after electroacupuncture at C4-C7 Jiaji (EX-B 2), with continuous wave for 5 min. This method and acupoint selection greatly influenced the therapeutic results (both P<0.05).
CONCLUSIONThe optimized therapeutic program of the immediate effect of acupuncture for cervical spondylosis of vertebral artery type is electroacupuncture + C4-C7 Jiaji (EX-B 2) + 5 min. The importance of different factors for the immediate effect in acupuncture treatment of cervical spondylosis of vertebral artery type is: acupoint selection > needling technique > time of needle retaining.

OBJECTIVETo investigate the absorption and transport mechanism of magnolol in Caco-2 cell model.
METHODSA human intestinal epithelial cell model Caco-2 cell in vitro cultured was applied to study the absorption and transport of magnolol, the effects of time, donor concentration, P-gp inhibitor verapamil, pH and temperature on the absorption and transport of magnolol were investigated. The determination of magnolol was performed by high performance liquid chromatography, then the values of apparent permeability coefficient (P app ) and P ratio Basolateral-to-Apical (BL-to-AP)/Apical-to-Basolateral (AP-to-BL) were calculated.
RESULTSIn Caco-2 cell model, comparing the amounts of transport of AP-to-BL and BL-to-AP, the latter was larger. At the same donor concentration, either the amounts of transport of AP-to-BL or BL-to-AP increased with increase in donor concentration and incubation time. Verapamil could significantly improve the amounts of transport of AP-to-BL. The transport of AP-to-BL and BL-to-AP depended on temperature, and there was no significant effect of pH on the transport of AP-to-BL.
CONCLUSIONMagnolol could be transported through the intestinal mucosa via a passive diffusion mechanism primarily, coexisting with a carrier-mediated transport, at the same time, the efflux mechanism could be involved.

OBJECTIVETo investigate the changes of mandibular vitodynamics in powerful bite working condition and impact working condition after mandibular angle osteotomy through 3-dimensional finit element analysis.
METHODSA patient of prominent mandibualr angle without malocclusion was selected and underwent 3-dimensional CT before and after operation. The DICOM data of 3-dimensional CT were read by Mimics software and 3-dimensional images were reconstructed. Then the 3-dimensional images were changed into IGES format and imported into ANSYS10.0. The boundary constrained condition and pre-processing condition was setting in ANSYS10.0 software. The 3-dimensional finite element models were generated in ANSYS10.0. Solution process was running and most powerful bite working condition and impact working condition were simulated and calculated.
RESULTSIn static stress analysis, the stress peak and stress maximal value point of mandible were basically at equal pace in preoperative and postoperative models. In transience dynamic stress analysis, although stress discrepancies were found in part time point and some region of mandible between preoperative model and postoperative model, the direction and topography of main stress were basically at equal pace. Main stress distributed beside external oblique line and concentrates at the neck of condyle. There was no significant difference of stress conduction and distribution between preoperative and postoperative models.
CONCLUSIONSCompared with preoperative model, postoperative model has different transduction phases of stress, but has almost the same tolerance extents of main stress.
