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:To evaluate the changes of lung morphologic features and oxidative stress in experimental diabetic rats. METHODS: The pulmonary structure of alloxan-induced diabetic rats were quantitatively studied with stereological methods. Changes of ultrastructure, activities of superoxide dismutase (SOD) and contents of malondialdehyde(MDA) of diabetic lung and serum were observed. RESULTS: The volume proportion of alveolar air and mean linear intercept of diabetic rats decreased remarkably in comparison with controls while the volume proportion of alveolar wall, the surface density of alveolar, the numerical density of alveolic area, the numerical density of alveolar and specific surface of alveolar increased significantly. The major change of the type II pneumocyte of diabetic rats was dilation of the rough endoplasmic reticulum (RER). The other findings in diabetic rats had included the presence of thickened alveolar epithelial, pulmonary capillary basal laminae and blood- air barrier, the volume density, the surface density, the mean profile area and the mean perimeter of RER in type Ⅱ pneumocyte of diabetic rats increased remarkably. And the specific surface of RER was significantly lower as compared with controls. SOD activity decreased and MDA content increased significantly in serum of diabetic rats as compared with the control group. SOD activity in the diabetic lung was not different from that of the control lung. However, the content of MDA obviously increased in diabetic lung. CONCLUSION: The morphologic features and oxidative stress in early diabetic rats are abnormal thus the lung should be considered as one of the “target organ”in diabetes mellitus.

Objective:To investigate the improvement in antibiotics use in our hospital by comparing the prophylactic application of antibiotics in type I incision before and after antimicrobial drug special rectification. Methods:The medical records of 100 hospital-ized patients undergoing I incision respectively from May to December in 2011 (before the rectification), from May to December in 2012 ( during the rectification) and from May to December in 2013 ( after the rectification) were withdrawn randomly. The prophylactic application of antibiotics was statistically and comparatively analyzed. Results: After the antimicrobial drug special rectification, the prophylactic application rate of antibiotics was reduced from 100% to 28%, and in 7 kinds of operations stressed by the National Health and Family Planning Commission ( inguinal hernia repair, thyroid disease, breast disease, arthroscopy, carotid endarterectomy, skull tumor resection and endovascular interventional diagnosis) , the prophylactic use rate of antimicrobial drugs was reduced to 11%. The variety choice of antibiotics in type I incision was more reasonable. The irrationality rate of medication time and course was de-creased obviously, and the accuracy of dosage and usage was improved significantly. The combination of antibiotics was also notably decreased. Conclusion:The antimicrobial drug special rectification is effective, which can significantly improve the prophylactic appli-cation rationality of antibiotics for type I incision in our hospital.

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.
