BACKGROUND: Research on selective attention of mobile visual information is relatively scarce because of difficulties in technology, methodology and experimental condition control. As is well known, most visual information in the real world is mobile and changeable. To examine the mechanism of mobile visual information is helpful to designing natural and highly efficient human-computer interface as well as selecting specialized personnel in special fields OBJECTIVE: To explore the distractive effect of the number, color, and form changes of distractors on multiple-target tracking performance. DESIGN: The present study was a 3 × 2 × 2 within subject design. Participants were undergraduates from Beijing Normal University.SETTING: Institute of Cognitive Neuroscience and Learning, Beijing Normal University.PARTICIPANTS: The experiment was performed in the Experimental Psychology Lab of Beijing Normal University in April 2003. Twenty-four undergraduates from Beijing Normal University participated in the experiment. Among them there were 11 males and 13 females aged 17-25 years.They all reported normal or corrected-to-normal vision and normal color perception.METHODS: ① Stimuli were presented on a 17-inch Founder monitor with the resolution of 1028 × 800 pixels. A Founder computer controlled the stimulus presentation and randomization of trials. Response latencies were collected by keyboard response with accuracy of one millisecond. The stimuli were randomly moving "日" characters. The number of "日" characters is 4, 8 and 12. As the participants were tracking the objects, the targets would transform to "(│)" and "(│)", and the distractors would change to "(│)" , "(│)", or "H" by removing lines from "日 ". All distractors and targets were red at the beginning of moving. ② The correct responses were analyzed with 3-factor repeated measures analysis of variance, multiple comparison analysis, and pairwise T-test.MAIN OUTCOME MEASURES: Response time and accuracy of pressing the keys.RESULTS: The data of 24 participants were involved in the final statistical analysis. ① The three-factor repeated measures ANOVA results showed that the main effect of the number change of distractors was significant [F(1,22)=6.040, P ＜ 0.05]. The further ANOVA and pairwise comparison in different experiment conditions also showed no distractive effects when target and distractor had different shape but the same color [F(1,2,3)=9.965, P ＜ 0.01]. The further pairwise comparison indicated that when the number of distractors was 2 and 6, the participants' response latencies had no significant effects, and they had significant effect when the number of distractors was 2 and 10, or 6 and 10 (RT10-RT2=46 ms, P ＜ 0.05, two-tail test; RT10-RT6=28ms, P ＜ 0.05, one-tail test). These results showed that the increase in the number of distractors had distractive effects. ② There had no significant effect whether target and distractor had the same color or not, when the number of distractors was 2 and 10. And there had significant effects whether the color of target and distractor was the same or not when the number of distractors was 6; the same shape of target and distractor produced distractive effects (Tsame colons=1.926; Tdifferent colons=2.044,P ＜ 0.05, one-tail test). The main effect of the color was not significant. The further pairwise comparison showed the same result. That is,the color change of diatractors had no obvious distractive effect.CONCLUSION: ① There was distractive effect when the number of distractors increased while the shape and color of distractor and target were different. ② There was no distractive effect when the number of distractors increased while the shape of distractor and target was the same. ③ There was distractive effect when the number of distractors increased while the shape of distractor and target was different, and there was distractive effect when the color of distractor and target was the same.

In this case-control study, the effect of insulin sensitivity on the genesis of cholesterol gallstones was not affirmed. However, raised 2h insulin level during glucose tolerance test and systolic blood pressure were risk factors in gallstone formation. Besides, less physical activity, lower serum total cholesterol and lower HDL-C concentration were found in patients with cholesterol gallstone.

AIM: The aim of this research is to study the earlier enzyme activity changes of the diaphragm in diabetic rats. METHODS: An enzyme histochemical method was used to observe the changes in the enzyme activities of dehydrogenases,hydrolases and oxidases in 4th week diabetic rat diaphragm. RESULTS: The activites of enzymes including SDH(Succinate dehydrogenase),MDH(Malate dehydrogenase), GDH(Glutamate dehydrogenase), ICDH(Isocitrate dehydrogenase), NADHD(NADH diaphorase), G-6-PD(Glucose-6-phosphate dehydrogenase), ACP(Acid phosphatase) and ANAE(Acid ?-naphtyl acid esterase) were increased in diabetic diaphragm compared with the control. LDH (Lactate dehydrogenase)and CCO(Cytochrome oxidase) activities were decreased, whereas NADPHD(NADPH diaphorase) showed no changes in diabetic rats. Eleven kinds of enzyme were analysed with image analysis.Optical density (A) of SDH, MDH, GDH, ICDH, NADHD, G-6-PD, ACP and ANAE in diaphragm of diabetic rats were significantly higher than that of control rats (P0.05). CONCLUSION: Increase in the aerobic capacity, decrease in the glycolytic capacity, and disturbance of lipid and energy metabolism were found in diaphragm of 4th week diabetic rats.

Objective In order to research the effect of tyrosine kinase inhibitor in combination with radiotherapy on the inhibi‐tion of breast cancer cells and breast cancer bearing nude mice .Methods Methyl thiazolyl tetrazolium (MTT) assay was used to e‐valuate the inhibition of different concentrations of TKI on breast cancer cells ,the breast cancer cells was divided into three groups :the TKI treatment group ,the cells in the control group (no the TKI processing) and the control group (non‐TKI and X‐ray irradia‐tion group) .The sensitivity of the cells in each group to X‐ray was compared by colony formation assay .MCF7 cells were xenograf‐ted in athymic nude mice to establish the animal model ,which was used to evaluate the effect of anti‐cancer .Results Colony form‐ing test showed that the separated use of any concentrations of the TKI inhibitor could inhibit the breast cells ,and the cell viability was significantly reduced;TKI combined with X‐ray irradiation could significantly increase the sensitivity of breast cancer cells to radiation ,and the difference was statistically significant(P<0 .05) .Compared to TKI inhibitor or X‐ray irradiation alone ,the combi‐nation of TKI inhibitor with X‐ray irradiation could inhibit the growth of tumor effectively .Conclusion The TKI inhibitor in com‐bination with radiotherapy can effectively inhibit the growth of breast cancer cells ,which provides a new theoretical basis for the im‐plementation of the clinical breast cancer radio sensitization .
