OBJECTIVETo observe the effect of detoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn on carotid intima-media thickness (IMT), plaque integral and plaque stability related serum indexes of patients with carotid atherosclerosis.

METHODSixty and four cases of carotid artery atherosclerosis patients were assigned randomly to 2 groups: detoxifying and blood circulation activating treatment group (treatment group, 32 cases) and control group (32 cases). Patients in treatment group were treated with capsules of extraction of polygonum cuspidatum and hawthorn, 1 pill po, bid (dosage of administration: polygonum cuspidatum extraction 5.33 mg x kg(-1) x d(-1), hawthorn extraction 5.0 mg x kg(-1) x d(-1)); patients in control group were treated with lovastatin 20 mg po, qd (dosage of administration: 0.33 mg x kg(-1) x d(-1)). The course of treatment was six months. To observe changes of IMT, plaque integral, and detect the level of plaque stability related serum indexes such as Hs-CRP, MMP-1 and TIMP-1.

RESULTAfter 6 months of treatment, in control group one patient quit the clinical trial because of liver dysfunction and one patient was rejected because of having not followed the therapeutic regimen. 32 cases in treatment group and 30 cases in control group were analyzed. The results showed that IMT and plaque integral of treatment group decreased significantly after the treatment (P < 0.05, P < 0.01), and there was no significant difference compared with control grope. Serum Hs-CRP, MMP-1 and MMP-1/TIMP-1 decreased after the treatment (P < 0.05, P < 0.01), and the treatment group was superior to control group in decreasing serum Hs-CRP (P < 0.05).

CONCLUSIONDetoxifying and blood circulation activating Chinese herb extraction of polygonum cuspidatum and hawthorn has good effect of anti-atherosclerosis and promoting plaque stability. Its mechanism might be related with anti-inflammation and inhibiting degradation of extracellular matrix, and deserves further studies.

Objective To investigate the imaging features of the nigrosomes-1 region in the substantia nigra at 3.0 T with enhanced gradient echo T2 star weighted angiography(ESWAN), and to explore its clinical value in the evaluation of Parkinson disease (PD). Methods Fifty-four patients diagnosed with PD (PD group), and 51 non-PD volunteers (N-PD group) were scanned with 3.0 T ESWAN, who had selected randomly. The widths of the typical high signal correspondence with the nigrosomes-1 region (a), the width at the middle of the substantia nigra (b) and the width of the banded high signal of which the oval structure were not displayed (c) were measured and collected. The result of reclassification performed by 2 physicians were compared with clinical gold standard. Specificity and sensitivity were calculated; Eleven outpatients with clinically suspected PD but undiagnosed (UD group) were continusouly selected. They received the same scanning and were performed with imaging diagnosis according to the conclusions of previous studies, then compared the imaging diagnosis with the final clinical diagnosis. Results In non PD group, hyperintensity of nigrosomes-1 were shown in 49 cases (96.1%) in bilateral or unilateral of the SN, the hyperintensity were shaped as“drop”, wedge or oval and the average size (a/b) was (0.31 ± 0.07)mm approximately; PD group, all 54 cases (100.0%) of the oval rear the“drop”were completely disappeared. The sensitivity of the loss of the hyperintensity of nigrosomes-1 for the diagnosis of PD was about 100.0%(54/54)and the specificity of it was about 96.08%(49/51). In UD group, 7 cases with the“drop”completely missed and 1 case with smaller“c”were clinically proven to PD, 2 cases with the typical hyperintensity and 2 case with larger“c”were proven to Parkinson plus syndrome. Conclusions The nigrosomes-1 typical hyperintensity in PD patients' substantia nigra on the 3.0 T ESWAN are disappeared. There may be an effective method for PD and Parkinson's plus syndrome identification that by analyzing of the presence or absence of the typical hyperintensity and its size in the patients with symptoms of PD.

Methods 86 patients with spinal cord injury were underwent urodynamic studies,all paients were undertaken uronoscopy and urine culture before and after urodynamic studies. Group A applied no special treatment after urodynamic studies, group B applied preventive antibiotic treatment. Results The incidence rate of urinary tract infection after urodynamic studies in group A was 8.81%, 7.32 % in group B. There was no significant difference between two groups. Conclusion Urodynamic studies are safe, well-tolerated procedures, need not use prophylactic antibiotic after urodynamic studies.

ObjectiveTo study basic pattern of normal youth in gait analysis.Methods28 healthy young persons as experimental subjects were studied. The gait analysis system based on digital video and digital image processing was employed to obtain kinematic parameters.ResultsThe means and standard deviations of kinematic parameters of normal youth were obtained. The differences of gait patterns between males and females were compared. The correlations between gait parameters and height, weight were analyzed respectively.Conclusions It is recommended that the values of the gait parameters and the trends obtained can be used as a standard gait pattern of normal youth. Statistically significant differences exist between the males and the females for most of the gait parameters. Furthermore, the differences of the values of gait parameters between the males and the females are not led only by the difference of height except very few parameters.

OBJECTIVETo explore the functional brain localization with magnetic resonance imaging (MRI) after acupuncturing the Yuan-Source and He-Sea acupoints of Stomach Meridian of Foot-Yangming (ST).

METHODSThe study was performed in 30 healthy volunteers who underwent acupuncture at Yuan-Source acupoint (Chongyang, ST42) and He-Sea acupoint (Zusanli, ST36) (ST group). Ten of these were also underwent acupuncture at the non-acupoints as the control group. Blood oxygenation level dependent functional MRI was performed.

RESULTSIn the ST group, signal increasing areas were demonstrated in bilateral superior temporal gyri (Broadmann 22), bilateral supramarginal gyri (Broadmann 40), bilateral cerebellar hemispheres, bilateral cingulate gyri and isthmus of cingulate gyri (Broadmann 32, 30), bilateral superior parietal lobules (Broadmann 7); signal decreasing areas were shown in bilateral orbital gyri (Broadmann 11), bilateral temporal pole (Broadmann 38), right inferior frontal gyrus (Broadmann 47) and right medial occipitotemporal gyrus (Broadmann 36). In the control group, signal increases areas were demonstrated in superior temporal gyri, precentral gyri, cingulate gyri, thalamus, insula and cerebellum. The size, signal intensity and number of increasing areas in control group are less than in ST group.

CONCLUSIONCombined acupuncture of Yuan-Source and He-Sea acupoints of ST can activate and decrease the multiple brain regions of "splanchnic brain" and thus reach a new functional balance to relieve pain.
