Objective To investigate the gender differences and the effect of three factors(the angle of rotation, left/right,palm/back) on hand mental rotation. Methods 40 healthy adults (20 males and 20 females, age; 18～26 years) were enrolled in this study. By simulation of human hand as picture stimuli,participants were instructed to decide as quickly as possible whether the stimulus was a left or right hand. The accuracy rate and reaction time of the behavior task were quantified. Results ① the subjects' reaction speed was far slower at 180° than 0°(P＜0.01). ②On judgment of 0° back picture,females were faster than males(left back: males( 1033. 16 ±245.85) ms,females( 853.15 ± 142.79) ms,P=0.014; right back; males( 973.07 ±217.11) ms;,females (796.28 ±146.67 )ms, P = 0.016). And,the right hand was responded faster than left hand,with statistical significance (males; P = 0.028, females; P=0.038). ③The time of females in judging the 0° hand back ( left (853. 15 ± 142.79) ms,right (796. 27 ± 146. 67 ms) ) was shorter than palm(left ( 1002. 72 ± 227. 91) ms,right ( 986.06 ± 230. 03) ms), reached statistical significance ( both at P ＜ 0. 001). In contrast, males in judging the 180° pictures, the speed of reaction to back(left ( 1252. 70 ±269. 35) ms,right ( 1216. 68 ±293. 54 )ms) was slower than palm with statistical significance (left: P ＜ 0. 01, right: P = 0. 015). Conclusion The three factors (angle of rotation,left/right,and palm/back) all exert effect on the behavior of hand mental rotation. It really has gender difference on hand mental rotation. Females response faster than males.

To investigate the role of ET 1 in the pathogenesis of SU, a model was established by cold restraint stress(CRS) inducing rat ulcer, immunohistochemistry(IHC)ABC method and radioimmunoassay(RIA) methods were used to determine ET 1 content and to study the expression and location of ET 1 in stomach of normal and CRS rats,and to evaluate the ulcer index(UI). IHC showed that ET 1 was stained as brownish grains,localized in the cytoplasm of vascular endothelial cells, stomach smooth muscle cells, gastric epithelial and vascular smooth muscule cells around lamina muscularis mucosae in stomach. The proportion of ET 1 positive cells was significantly higher in 3h poststress gastric mucosa than in normal gastric mucosa in rats by IHC( P

Purpose: To study the immunophenotype and the expression of cytotoxic granule proteins of nasal NK/T cell lymphoma and its significance. Methods: 44 cases of nasal NK/T cell lymphoma were studied by the two-step method of DAKO EnVisionTM using a series of antibodies including CD3, CD20, CD43, CD45, CEI45RO, CD56, CD57, CD79?, TIA-1, granzyme-B and perform. Results: All the cases of nasal NK/T cell lymphoma were CD45 positive. 43% of the cases expressed CD3 with positive signal located in the cytoplasm, which was different from peripheral T cell lymphoma. 45% and 52% of the cases were CD43 and CD45RO positive respectively. Cases that reacted to CD56 accounted for 52% of the cases, 43% of which were also positive to CD3. Concerning the reactions to both CD3 and CD56, 10 cases showed CD3 + CD56 + , 13 showed CD3-CD56 + , 9 were CD3 + CD56- and 12 were CD3-CD56-. None of the 44 cases showed positive reaction to CD20, CD79? and CD57. All cases were reactive to TIA-1. 93% and 95% of the cases showed the reactions to granzyme-B and perform. All the controls were negative to TIA-1, granzyme-B and perform. Conclusions: The immunophenotypes of nasal NK/T cell lymphoma showed less consistency. CD56 was not always positive in the cases of this tumor. The different locations of the positive signal to CD3 showed that the cell lineage of this tumor was different from T lymphocytes. The high frequency of the staining by cytotoxic granule proteins, TIA-1, granzyme-B and perform, showed that these cells may have originated from NK cells. The distinctive differences in immunohistochemical staining of cytotoxic granule proteins in nasal NK/T cell lymphoma make their detection very useful and important in diagnosis and differential diagnosis.

ObjectiveTo investigate the effects of eyes-closed (EC) and eyes-open (EO) EEG field powers on the auditory P300 evoke potentials.MethodsThe EEG was recorded in 12 healthy male college students (20 ～24 years) respectively in their eyes-closed and eyes-open states,and then the auditory P300 paradigm was performed.Results① Alpha band was distributed at the posterior-occipital area,while Alpha-1 (7.5～9.5 Hz) field power were EC as (2.62 ±0.81 ) μV2 and EO as ( 1.80 ±0.56) μV2,with statistical significance (P ＜ 0.01 ) ; Alpha-2 ( 10 ～ 12 Hz) field power were EC as ( 8.55 ± 1.85 ) μV2 and EO as (4.95 ± 1.59 )μV2,also with statistical significance (P＜0.05).②In P300,the Common stimulus elicited clear component N1 (90ms)and P2 (180ms) in the ERPs after stimulus,while there were no significant differences between EC and EO states.Correspondingly,the rare stimulus elicited clear component N2 (207 ms) and P3 (313 ms) in the ERPs after stimulus on-set.Comparing the differences of field potentials of the rare stimulus between the two states,N2field potential in EC ( (0.01 ± 0.71 ) μV) was smaller than that in EO ( ( - 2.13 ± 0.80 ) μV ),with statistical significance (P ＜ 0.05 ) ; while P3 field potential in the EC ( ( 4.16 ± 1.08 ) μV ) was smaller than that in EO ( (4.78 ± 1.20) μV),but without statistical significance (P ＞ 0.05 ).ConclusionThe alpha field power is higher in eyes-closed than in eyes-open state,while performing the same auditory P300 paradigm,significant reduction of field potential in the N2 component are observed in eyes-closed than in eyes-open state.

OBJECTIVE To investigate the distribution and resistance of clinical isolates to antimicrobial agents commonly used.Antimicrobial agents should be used rationally based on the results of susceptibility testing.METHODS The clinical isolates were identified with W/A-40 or VITEK-32.The results were analyzed by WHONET 5.3 software according to CLSI 2005.RESULTS A total of 2892 clinical isolates were collected in 2007.Gram-negative bacilli accounted for 68.2% and Gram-positive cocci accounted for 31.8%.The top eight pathogens were Pseudomonas aeruginosa,Escherichia coli,Klebsiella spp,Acinetobacter spp,coagulase-negative Staphylococcus,Enterobacter spp,Serratia spp and S.aureus.About 76.4% of S.aureus isolates were MRSA,81.6% of coagulase-negative Staphylococcus isolates were meticillin-resistant.Under 20.0% of Enterobacteriaceae strains were resistant to cefoperazone/sulbactam,imipenem and piperacillin/tazobactam.About 16.3% and 32.5% of P.aeruginosa isolates were resistant to cefoperazone/sulbactam and imipenem.CONCLUSIONS Gram-negative bacilli were dominant isolates in our hospital during 2007.P.aeruginosa is the most frequent pathogenwith severe antibiotic resistance.Enterobacteriaceae are susceptible to cefoperazone/sulbactam and imipenem.
