Objective To evaluate the feasibility of using a microsensor motion capture unit (MCU) to assess the reaching characteristics of hemiplegic stroke patients. Methods Twenty-three hemiplegic stroke patients with an average age of (61 ± 11) years and ten normal subjects of matching age were asked to sit on a chair and use the affected arm (for the patients) or the right arm (for the normal subjects) to reach for a cup on a table just in front of the shoulder at arm's length away.Four small sensor boxes which could detect movement and its speed and smoothness in three dimensions were fixed to the subject's spine,upper arm,forearm and hand.The test was repeated four times after two trial runs.The average velocity,peak velocity,degree of joint dispersion,entropy of acceleration,joint coordination and active range of motion ( AROM ) of the shoulder were analyzed.The patients and normal subjects were statistically compared.The results were correlated with Fugl-Meyer upper extremity scores using Spearman correlation analysis. Results All of the measured variables showed significant differences between the patients and normal subjects.In the correlation study,the average velocity,peak velocity,AROM of the shoulder and joint coordination showed significant correlation with the Fugl-Meyer scores.There was,however,no significant correlation between degree of dispersion of the shoulder or elbow joints or the entropy of acceleration ( which represented the quality of movement) and Fugl-Meyer upper extremity scores. Conclusions The results suggest that microsensor MCUs can quantitatively assess the kinematics of reaching among hemiplegic stroke patients.They can provide valuable and objective data about the functional quality of multiple joint movements in three dimensions.

OBJECTIVE: To explore the association between low flow rate and reperfusion injury during the process of preserving liver by cold machine perfusing perfluorochemical oxygen carder solution. METHODS: Forty-four male adult Wister rats were randomly divided into normal, control, experimental Ⅰ and experimental Ⅱ groups. In the normal group, the removed liver was performed isolated reperfusion guided by Clavien method. In the other 3 groups, the removed liver was infused through the portal vein by the 4-5 ℃ conserved perfluorochemical oxygen carder solution. The infused rate was controlled at 0.4, 0.2, 0.1 mL/(min·g) with 18 hours perfusion, After that, isolated reperfusion was performed. The activity of aspartate aminotransferase, alanine transaminase and endotheiin mass concentration of the effluent was detected at minutes 10, 30, and 60 after reperfusion. The histopathological changes of liver under light and election microscopy were also observed. RESULTS: The activity of aspartate aminotransferase, alanine transaminase and endothelin mass concentration had no remarkable differences between the experimental Ⅰ group and control group (P > 0.05). The differences between the experimental Ⅱ group and control group were remarkable (P < 0.05). The light and electron microscopy showed that the histopathological changes of liver in the control and experimental Ⅰ groups was lightener than experimental Ⅱ group. CONCLUSION: During the process of preserving liver by cold machine perfusion, the rate of 0.1 ml/(min·g) perfluorochemical oxygen carder solution increase the injury of hepatocyte and sinusoidal endothelial cells, which eventually result in severity of reperfusion injury.

OBJECTIVEThis paper aims to study the effects of gossypol acetic acid (GAA) on proliferation and methylation level of human MutL homologue 1 (hMLH1) gene in human tongue cancer cell line Tca8113.
METHODSThe MTT assay was used to determine the effects of the acid on the proliferation inhibition in Tca8113 cells treated with different GAA concentrations. Nested methylation-specific polymerase chain reaction (nMSP) was used to detect the change in the methylation level of hMLH1 after 48 and 72 h with 30 and 15 micro mol L(-1) GAA treatment.
RESULTSMTT assay results showed the growth and proliferation inhibition of Tca8113 cells in the experimental GAA group after 24 h to 72 h of GAA treatment. The nMSP results indicated that the average optical density of hMLH1 in the Tca8113 cells significantly changed after the GAA treatment (30 micro mol L(-1) GAA for 48 h and 15 micro mol L(-1) for 72 h) (P<0.05) compared with that of the control group.
CONCLUSIONGAA does not only inhibit Tca8113 proliferation but also has a demethylation effect on the hMLH1 gene. These phenomena may be part of an underlying tumor-suppression mechanism of GAA.
