Abstract?AlM: To evaluate the difference of contrast sensitivity ( CS) in photopic and scotopic environments in eyes with myopia and myopic astigmatism operated with femtosecond laser in situ keratomileusis ( femto-LASlK ) and laser in situ keratomileusis ( LASlK) .?METHODS: ln a prospective study 160 myopia and myopic astigmatism patients' eyes were involved, which accepted femto- LASlK or LASlK in our hospital from January 2010 to February 2012. The myopia degree was -1. 50 ~ -10. 00D, the astigmatism degree ≤-6. 0D. Eighty eyes were treated with femto-LASlK in group A, and 80 eyes were treated with LASlK in group B, All patients in the treatment group completed the final 6mo of follow-up. The uncorrected visual acuity ( UCVA) and the best spectacle-corrected visual acuity ( BSCVA) , objective and manifest refractions, results of slit-lamp examination, the side effects, intraocular pressure, corneal topography, CS in photopic and scotopic environments were noted.? RESULTS: All of operations on 160 cases were successful without severe complication after 6 mo follow-up. CS of femto-LASlK group ( group A) at each spatial frequency environment were higher than that of LASlK group (group B). ln group A, after 1mo the photopic CS, after 3mo of scotopic CS recovered to the preoperative level, 6mo after surgery improved than before the operation. ln group B, after 3mo photopic CS to the preoperative level, scotopic CS at 6mo after operation was still not recovered to the preoperative level.?CONCLUSlON:Femto-LASlK for correction of myopia and myopic astigmatism, in improving the postoperative contrast sensitivity under shade environment has more advantages than LASlK.

Objective To investigate the relationship between self-esteem and social anxiety,and the role of putting into perspective played in this relationship in university students.Methods Sample consisted university students of 376 females and 164 males,data were obtained on cognitive emotion regulation questionnaire,social anxiety subscale of the self-consciousness scale,and self-esteem scale.Results Cognitive emotion regulation strategies of putting into perspective is significantly and positively related to self-esteem(r=0.12,P＜ 0.01),it was also significantly and negatively related to social anxiety(r =-0.01,P ＜ 0.05) ; self-esteem was significantly and negatively related to social anxiety(r =-0.35,P ＜ 0.001).Cognitive emotion regulation strategies of putting into perspective played both a moderating(AR2 =0.124,P＜0.05) and mediating role(F=30.717,P＜ 0.01) in the relationship between self-esteem and social anxiety.Conclusion Self-esteem is not only directly but also indirectly associated with social anxiety because of the moderation and mediation model of putting into perspective.

Objective To investigate the attentional bias for emotionally faces in subjects with low-trait anxiety when they are under normal or induce-fear emotion.Methods Trait anxiety inquiry(T-AI) were used to evaluate the mental health status of 480 freshman in a university,and 450 valid questionnaires were obtained.Among them,90 students were identified as low trait anxiety.Sixty students from them were randomized into 2 group(n=30) to receive a dot-probe task with emotional face as stimulus.They were asked to judge the target.The attentional bias under normal or fear-induced emotion to the emotionally faces was examined.Results Low trait anxious college students showed attentional avoidance to the negative faces when they were under normal emotion [D=(-11.09?25.40),t=-2.391,P=0.024],and the orientation was significant [OI=(-20.28?22.90),t=-4.850,P0.05].Conclusion Low trait anxious college students have attentional avoidance to negative faces because of orientation,but the avoidance will disappear when they are under fear emotion.

Objective To screen out the individuals at high cognitive risk by using the weakest link theory,and explore the characters of the cognitive emotion regulation.Methods 600 undergraduate students were tested with cognitive style questionnaire,general social and academic hassles scale,center for epidemiologic studies depression scale,and cognitive emotion regulation questionnaire.Results There were significant differences between individuals of high and low cognitive risk in self-blame (13.32 ± 2.12) vs (12.45 ± 2.27),rumination,catastrophizing,blaming others,positive refocusing and positive reappraising.Catastrophizing,generality,rumination,positive reappraising,stress,self-blame,and self could predict 34.2％ of depression.Conclusion There are differences between individuals of high and low cognitive risk in cognitive emotion regulation.Catastrophizing,generality,rumination,positive reappraising,stress,self-blame,and self are the main predictors of depression.

Objective To investigate the relationship between head nurse's authentic leadership and degree of solidarity among nurses in operating room.Method A total of 120 nurses in the operation room of 3 general hospitals in Jiamusi City were enrolled in the study by way of the questionnaire on authentic leadership and the scale of solidarity.Results The mean score on the head nurse's authentic leadership (41.28 ± 8.48) was above the middle-high level.The mean score on the solidarity (68.67 ± 8.82) was in the middle-high level.There was a positive correlation between the head nurses' authentic leadership and the degree of solidarity among nurses in the operating room.Conclusion Hospital and nursing administrators should take active and effective measures to improve the leadership of head nurses so as to improve the degree of solidarity among nurses in the operating room as well as the quality of nursing.

Objective To assess the CT image quality of the pure ground glass nodule(pGGN)in chest phantom by using different field of view(FOV)and matrix.Methods CT(Philips Brilliance 128 spiral CT)scans were performed on chest phantom containing 9 artificial pGGNs(diameter≥5 mm)in 3 different FOV (50 mm,150 mm,300 mm ),and were reconstructed in 2 different matrix(512×512, 1 024×1 024),standard kernel.Recorded the CT values and standard deviations (SD)of the nodules and surrounding regions in different FOV and matrix,and calculated the mean standard deviation(MSD),contrast noise ratio (CNR)and signal noise ratio (SNR),then compared the difference among them.Two radiologists assessed the image quality of the pGGNs in blind method respectively,then evaluated the coherence between them using Kappa testing.Results The coherence of 2 observers was substantial or almost perfect.No significant differences were found on MSD,CNR and SNR in different FOV (P value>0.05)when matrix was kept,whereas the visibility of the nodules improved with the FOV changing smaller.And there were significant differences all on MSD,CNR and SNR by using different matrix when FOV was kept.The MSD increased and the CNR,SNR decreased in high-resolution group.The visibility of the pGGNs was not improved obviously in high-resolution group.Conclusion The image quality of the pGGN(diameter≥5 mm)won’t be changed by using smaller FOV when matrix is kept ,but the visibility will be improved with the FOV changing smaller.When FOV is kept,the MSD increased and the CNR,SNR reduced in high-resolution group,but the visibility will not be improved obviously compare to the standard resolution group.

Background Epidemiologic studies found that the incidence of myopia is higher in Hong Kong and Taiwan regions of China than that of the mainland.So whether the general reading words with traditional Chinese characters and simplified characters is associated with myopia deserves attention.Objective This study was to test the accommodative responses and the regression levels of nearwork-induced transient myopia (NITM) induced by traditional complex Chinese characters and modern simplified ones in the same size,and to explore the differences and inherent relationship of the accommodative regulations based on the structures of the two types of Chinese character in causing reading triggered myopia.Methods Twenty two volunteers aged 24-29 years were included in this study with informed consent.The corrected vision of both eyes from each subject was ≥ 1.0 with a mean spherical equivalence of (-1.86±2.34)D.Accommodative response was tested with 4 different reading texts using the rapid sequence visual presenting model with the GRAND SEIKO-WV5500 infrared autorefractor,and this procedure was performed after full correction of refractive error.An initial test of looking at a certain distance was performed (as baseline),and then the subjects read intensively at the targets for 10 minutes at 33 cm to calculate the accommodative responses.After a 10 second pause,the ocular refractive status was obtained exactly at 15 seconds,20 seconds.The one-way ANOVA method was used to determine the effects of the different font types and sizes on the adjustive responses and the causation of NITM.Results Accommodative response induced by simplified and traditional Chinese characters showed an accommodative lag of (1.11 ±0.38),(0.95 ±0.43),(1.18 ±0.33) and (1.06±0.28) D,showing a significant difference among the 9 pt and 12 pt simplified and traditional Chinese characters (F =1.62,P =0.19),and significantly different accommodative lag values between 12 pt simplified characters and 9 pt traditional characters was found (t =5.56,P =0.02).NITM induced by the four different targets were (-0.45 ±0.45),(-0.47 ±0.46),(0.45 ±0.82) and (-0.46±0.78) D in the 4 types of characters,without a significant difference among them (F=0.01,P =0.99).Conclusions Near-distance reading causes accommodative lag regardless of the type of reading texts.The target demonstrated stimuli spatial frequency and font size play an impact on accommodative responses.NITM appears when one reads simplified or traditional Chinese for 10 minutes.The accommodative lag and NITM trend might be responsible for the onset or regression of myopia,yet it is not supportive for the hypothesis that reading traditional Chinese causes more strain since there is no difference between the two.
