Objective To observe the effect of acupuncture on patients with vertebral-artery-type cervical spondylosis by means of transcranial Doppler sonography ~TCD) and brainstem auditory evoked potentials ~BAEP), and to explore the mechanism of acupuncture in treatment of cervical spondylosis by means of blood velocity and neuroelectrophysiology measurements. Methods Forty patients with vertebral-artery-type cervical spondylosis were divided into acupuncture treatment group ~20 cases) and routine treatment group ~20 cases). The TCD and BAEP were examined before the rehabilitation treatment and 2 week later. Comparing with the control group, the effect of acupuncture on the blood velocity and cerebral electrophysiology was analyzed. Results ~1)The total efficiency rates in the two treatment groups were 90% and 85%, respectively. The clinical heal rate was 45% in acupuncture group and 35% in routine group. There was no statistic difference with regard to the therapeutic effect and the length of treatment between the two groups. ~2)The blood velocity of vertebrobasilar artery ~VBA) in the patient group was decreased. The abnormal rate of TCD was 77.5% ~31/40 cases), characterized with the decrease of VBA. The abnormal rate of BAEP was 75% ~30/40 cases), characterized with brainstem abnormality type. ~3)The blood velocity in both groups was increased after treatment. Compared with the routine therapy group, the velocity of blood flow in vertebral artery in acupuncture treatment group was increased markedly ~P

Objective To explore resting state network in patients with hepatic cirrhosis using functional magnetic resonance imaging(fMRI).Methods 14 patients with hepatic cirrhosis and 14 healthy volunteers were included in this study.Modified Stroop task in Chinese character was used as target stimulus,block-design fMRI was used to acquire resource data.Group analysis(control epoch minus task epoch) was performed for both tasks in both groups.Results Comparing with controls,the patients with hepatic cirrhosis had abnormal deactivation mode.The absence of posterior cingulate cortex(PCC) and precuneus was present when performing incongruous word-reading task,deactivation of PCC,precuneus,and ventral medial prefrontal cortex were increased when performing incongruous color-naming task.Conclusion Cirrhosis patients have abnormal deactivation mode,the absence of PCC and precuneus is a sensitive not specific biomarker in detecting the brain changes of the patients with hepatic cirrhosis.

Objective To study the best parameters of low dose MSCT in examining the pharyngeal disease.Methods 20 volunteers were scanned by MSCT using 10 mm collimation,10 mm interval,120 kV,200 mA,100 mA,50 mA,25 mA parameters,respectively.All of the data was reformed(collimation 2.5 mm,interval 1.3 mm) on ADW 4.0 workstation.The image quality in different dose were scored respectively by 4 experienced radiolagists. Results The best appropriate parameter was 10 mm collimation,10 mm interval,120 kV,50 mA.Conclusion In examining the pharyngeal disease,the application of low dose(120 kV,50 mA) scan mode not only can assure the image quality but can decrease the exposure to patients.

Objective To investigate the effect of enteral nutrition on patients with COPD during acute exacerbation stage. Methods Subjects hospitalized for an acute exacerbation of COPD (n=58) were assigned into two groups: enteral nutrition group (n=33) or parenteral nutrition group (n=25). The blood indexes of nutrition at day 5 and day 10,the incidence of complication and the mortality were observed. Results Less decrease of serum proteins was detected in the enteral nutrition group as compared with that in the parenteral alimentation group (day 5 P

Objective To perform Low dose dynamic MSCT( multi-slice CT) in sleeping obstructive sleep apnea syndrome ( OSAS) patients correcting the imprecise measure values in waking state, and to exactly analyse the location and extension of the dynamic changes about the condition. Methods Sixteen OSAS patients were scanned both in waking and naturally sleeping period ( end phase of inspiration and expiration). Measured at the narrowest part of the retropalatal ( RP) and retroglossal ( RG) and 5 mm under the tip of epiglottis at the epiglottal ( EPG) at the end period of inspiration in sleeping, respectively, and compared the accurate pos(?)on of the narrowest or occlusive level in 3 phases. All patients were also scanned using cine mode at the narrowest level at the end period of inspiration in sleeping to show the pharyngeal cavity changes during sleep. Results The smallest XSA of RP region (Mw = 47. 50 mm2 ,Me =73. 00 mm2 , Mi =2. 00 mm2 ;Zwe =2. 897,Pwe =0. 003 ;Zwi =4. 192,Pwi

ObjectiveTo explore the therapeutic effect of floating acupuncture on the the processus transverses of vertebrae lumbales Ⅲ syndrome.Methods40 patients with the processus transverses of vertebrae lumbales Ⅲ syndrome were divided into the floating acupuncture group (20 cases) and the traditional group (20 cases). The pain was evaluated with visual analogue scale (VAS) before and after treatment.ResultsCompared with traditional treatment, the floating acupuncture can relieve pain rapidly after 15 min and 1 d of treatment. ConclusionThe floating acupuncture shows preferable clinical curative effect to patients with the processus transverses of vertebrae lumbales Ⅲ syndrome.

Objective To optimize human acellular dermal matrix(ADM) and evaluate its biological characters. Methods Human skin was treated with hypertonic saline followed by NaOH maceration(group A), hypertonic saline followed by sodium dodecyl sulfate (SDS) detergent(group B) or Dispase Ⅱ followed by Triton X-100(group C), the resulting ADM were sectioned, and then were stained by special immunohistochemistry method. The cytotoxicity of them were evaluated by methyl thiazolyl tetrazolium (MTT) colorimetry and then cell compatibility was analyzed by cell culture;The optimized ADM resulted was choosen for use. Fibrablasts(FBs)were transfected with adenovirus vector encoding green fluorescent protein gene(Ad-GFP)and the growth of them on the optimized ADM was observed by fluorescent microscopy. Results Collagen and elastic fibers can still be observed in three kinds of ADM. The cells in dermis can be disintegrated both in group A and C, but not in group B. The cytotoxicity scores of the ADM prepared in group A and B were grade 0 or grade 1, while that of group C was more than grade 1.The ADM prepared by NaCl-NaOH maceration had good biocompatibility. There was statistical difference in adhering number of NIH3T3 cells in group A and B. NIH3T3 cells grew well in group A and the resulted ADM was optimized. FBs transfected with Ad-GFP grew well in the optimized ADM. Conclusion The ADM prepared by NaCl-NaOH maceration was a good tissue engineering biomaterial with a little cytotoxicity and rich in resouce.

Objective To determine the volume reduction of the primary olfactory cortex (POC) in patients with Alzheimer disease (AD) and investigate the potential relationship of functional olfactory activation and anatomical atrophy changes. Methods Twelve patients with AD, eight patients with mild cognitive impairment (MCI) and twenty normal controls (NC) underwent standardized UPSIT (University of Pennsylvania smell identification test) behavior smell test and neuropsychological tests. Then all of the subjects underwent the high resolution MRI and an olfactory fMRI scan on a 3T system. Volumetric measurement of the POC was conducted and the areas were also saved as a ROI which would be used during the processing of fMRI data to get the activation voxels in local region. The Kruskal-Wallis rank test was used to examine the significance of POC volume and activation in three groups, If P-value was less than 0.05,Bonferroni method was used for multiple comparisons. The correlation between the anatomical volume and functional activation was analyzed with partial correlation adjusted for age. Results The POC volume of NC, MCI and AD groups were 3024--4734, 1409--4553 and 1561--3759 mm~3, and the medians were 3749, 2752 and 2156 mm~3. The activation voxels of each group were 0--2360, 0--2160 and 0--100 mm~3, while the medians were 430, 40 and 0 mm~3. There were significant differences of both POC volume atrophy and activation between the three groups, with a trend of reduction from NC to MCI to AD group (H is 14.942 and 16.587, both P<0.05). The volume of olfactory activation at POC was highly correlated with the volume of POC (r=0.364, P=0.023). Conclusions In this study, we explored the morphological and functional changes in the POC. It is revealed that POC suffers prominent local atrophy and dysfunction as well as hippocampus in AD. These results can provide neuropathological and neurofunctional bases for olfactory deficit in Alzheimer Disease.
