Objective:To examine the relationship between cross-ethnic friendship and cross-ethnic face perceptual memory in the regions where the population ratios of the Uygurs and the Hans are different.Methods:According to demographic criteria,33 Han college students with lower contact with Uygurs from the area where Uygur and Han population ratio was 1 ∶ 9,32 Uygur college students with lower contact with Hans from the area where Uygur and Han population ratio was 9∶1,and 32 Uygur with higher contact with Hans and 34 Han students with higher contact with Uygurs from the area where Uygur and Han population ratio was 4∶6 were recruited in the study.Relying on E-prime program,the learning-recognition paradigm was adopted to compare the difference between the participants'recognition for faces of one's own race and others.Meanwhile,based on self-reported Friendship Quality Questionnaires,participants'Time Spent and Intimacy with out-group friends were assessed as the measurement of inter-group friendship.Results:The accurate rate,false alarm rate and discrimination accuracy demonstrated a significant own-race advantage for the Uygurs with lower contact and higher contact with the Hans (Ps ＜ 0.01),whereas the Hans with higher contact and lower contact with the Uygurs did not show significant difference between own-race faces and other-race faces on these variables (Ps ＞ 0.05).Stepwise regression analysis showed that the regression coefficients of the interracial intimacy and time spent with out-group friends toward the magnitude of crossrace effect were stably significant (β =-0.87,-0.56,Ps ＜ 0.01).Conclusion:The Uygur and Han students may prefer different encoding strategies in face recognition,and inter-group friendship experience may be an appropriate variable for predicting the ability to recognize other-race faces with good reliability and validity.

Objective To investigate the value of serum α1 acid glycoprotein(AAG) and Homocysteine(Hcy) in different stage of renal damage in type 2 diabetes(T2DM ) .Methods a total of 128 patients with T2DM were recruited from January 2013 to Octo‐ber 2013 ,According to 24 h urinary albumin excretion rate (UAER) were divided into the first group ,the second and third groups , and choose 80 healthy cases over the same period as the normal control group .Serum AAG ,Hcy ,creatinine (Cr) and blood urea ni‐trogen (BUN) were detected ,the test results were analyzed statistically .Results There were significant differences in type 2 diabe‐tes mellitus group ,early diabetic nephropathy group ,clinical diabetic nephropathy group of the serum AAG ,Hcy levels(P<0 .05) , there were positively correlated (r=0 .673 ,P<0 .05) between UAER and serum AAG levels ,and were positively correlated (r=0 .35 ,P<0 .05) between UAER and Hcy levels .Conclusion Combined detection of serum AAG ,Hcy have a significant for early diagnosis of diabetic nephropathy and assessing the degree of renal injury in diabetes .

Objective To investigate the imaging diagnosis of vocal cord paralysis.Methods Of 58 patients,53 cases was unilateral and 5 bilateral.All patients underwent laryngeal tomography and 6 of them underwent CT.The imaging findings were analyzed.Results The tomography findings of unilateral vocal cord paralysis were as follows:dilated piriform sinus,41.5%;asymmetrical vestibule,39.6%;enlarged ventricle,71.7%;thinning cord,47.2%;paralyzed cord higher than intact cord,73.6%;cord fixed in adducent position during inspiration,100%;tilting of the thyroid cartilage,11.3%.The cord fixed in paramedian was the main appearance of bilateral vocal cord paralysis.The CT features of vocal cord paralysis included dilated piriform sinus(6 cases),enlarged laryngeal ventricle(4 cases),fixed cord in paramedian position(4 cases)and tilted anteromedially arytenoid cartilage(5 cases).Conclusion To evaluate the functional abnormality of larynx,tomography is useful and CT is well to display the laryngeal anatomic structures and changes,therefore,if the diagnosis is uncertain by tomography or the intrinsic lesions of larynx is suspected,CT is recommended.

OBJECTIVETo develop a standard Neglect Evaluation Scale which is suitable for rural primary school students in China.

METHODSAccording to the principle of multi-stage stratified cluster sampling, a field investigation was conducted among primary school students in 28 counties from 7 provinces and 2 municipalities. The questionnaires were self-designed, and determined by multiple rounds of pilots and revisions. Among 5 862 students, 2 792 (6-8 years' old) and 3 070 (9-11 years' old) were investigated by using two kinds of Neglect Evaluation questionnaires, respectively. After project analysis, factor analysis, reliability and validity analysis, the reliability and stability of the scale were tested. Then percentile method was used to determine the evaluation standard to develop and finalize the formal scale.

RESULTSThe numbers of the remaining items for 6-8 year-old group and 9-11 year-old group is 69 and 58, respectively, both of which contain six levels of neglect, including body, emotion, health care, education, security, and society. 4 times of factor analysis were conducted in both of the two groups. The factor loadings in these two groups were 0.290-0.700 and 0.276-0.729 respectively. Reliability test results showed that the two kinds of scales' Cronbach alpha coefficient were 0.924 and 0.929 respectively, split-half reliability were 0.891 and 0.904 respectively, the retest reliability were 0.559 and 0.892 respectively, the differences were statistically significant (P < 0.05). The retest reliability among 6-8 year-old group in medical neglect level had no statistical significance, but was close to the cut-off point (P = 0.054). The test results of external validity indicated that both of the two scales could reflect the neglect status of the subjects (P < 0.05), but the subjective and objective evaluation towards neglect were not consistent. The cut-off points for judging whether the children were neglected or not among 6-8 year-old and 9-11 year-old groups were 159 and 137 respectively; and the adjusted values were 160 and 135 respectively.

CONCLUSIONThe two norm scales developed by this study showed good discriminability, reliability, validity, and stability. The norms developed on the basis of the scales was suitable for the situation of rural students in primary schools in China.

OBJECTIVETo analyze pupils' neglect status aged 6-11 years in China's rural.

METHODSAccording to the principle of multi-stage stratified cluster sampling, to extract 7,943 pupils aged 6-11 years for the survey from 56 primary schools in 28 counties in nine provinces, from December 2012 to March 2013. Proceed questionnaire survey by the scale from "Neglect Evaluation Norms for pupils aged 6-8 years in Rural Areas of China" and "Neglect Evaluation Norms for pupils aged 9-11 years in Rural Areas of China". And analyze neglect rates and neglect degrees of the different grades, gender, family types and different levels of neglect.

RESULTSThe total neglect rate of China's rural pupils aged 6-8 and 9-11 years was 40.2% (1,258/3,130) and 42.5% (1,498/3,526) respectively, which differences had no statistical significant (χ2=3.59, P=0.058); the total neglect degree was 46.04±8.87 and 44.78±10.43 respectively, which differences had statistical significant (t=5.01, P<0.001); the differences of neglect rates and neglect degrees between male (41.4% (657/1,587) and 46.28±8.76) and female (39.0% (601/1,543) and 45.78±8.97) of aged 6-8 were all no statistical significant (χ2=1.87, P=0.171; t=1.49, P=0.136); the neglect rates and neglect degrees of male (46.3% (816/1,763) and 45.53±10.11) were higher than female (38.7% (682/1,763) and 44.06±10.69) in the group of aged 9-11, which differences were all statistical significant (χ2=20.84, t=3.97, P<0.001); the male neglect rate in the group of aged 6-8 in social neglect (11.7% (198/1,691)) and the neglect degree in educational neglect (48.09±9.70) were higher than female (9.4% (155/1,648) and 47.37±9.89), which differences were all statistical significance (χ2=14.55, P<0.001, t=2.22, P=0.026), the male neglect rate in the group of aged 9-11 in physical neglect (20.4% (398/1,954)) was higher than female (16.7% (326/1 957)), which differences had statistical significance (χ2=8.92, P=0.003).

CONCLUSIONThe neglect status of Chinese pupils aged 6-11 years in rural was serious, and we should find out risk factors and provide efficient prevention measures.
