Objective This paper aims at developing a survey tool for pressure ulcer prevention and testing its reliability and validity. Methods Through reviewing the domestic and foreign literatures and discussing repeatedly, item pool for pressure ulcer prevention and initial survey tool were developed.3 rounds of Delphi consultation were used to acquire experts′opinions for amending, perfecting the survey tool and calculating the content validity index. Investigations were performed by 70 nurses who were trained with the cross sectional survey on pressure ulcer prevention of 2047 patients from a top three hospital. The consistency reliability and con-struct validity of survey tool were then analyzed based on the survey results. Results The positive coefficient of experts in the 3 rounds of consultation were all 100%. The authority degree of the experts was 0.830. The coefficient of variation in the 3 rounds of con-sultation were 0.000-0.241,0.000-0.235 and 0.000-0.234 respectively. Kendall′s coefficient of concordance W were 0.115,0.174 and 0.214(P<0.001). The content validity index was 0.954. The Cronbach′s alpha was 0.824 from 2047 patients investigated by the 70 nurses. Exploratory factor analysis got two common factors which explained 75.351% of the total variance. The factor loading was 0.585-0.857(>0.400) respectively. Conclusion The survey tool for pressure ulcer prevention has good reliability and validity. It can be used to investigate pressure ulcer prevention of Chinese hospitalized patients.

Objective To discuss the clinical aesthetic effect of vermilion repair on cleft lips after using double-line reconstruction.Methods 68 children with cleft lip were repaired according to the principle of double-line reconstruction,and two contents including 7 projects,such as shapes of upper lips,vermilion borders of lips,vermilion shapes and lips,etc,were evaluated comprehensively within one month after operation for assessing the postoperative effect.Results 68 cases were followed up,with the follow-up rate of 100％,and 62 cases (91.2％) were satisfied with the vermilion repair.Six cases (8.8％) had a common effect of vermilion shapes after repair.In the 7 contents evaluated,satisfactory results were achieved in the projects except the relatively poor symmetry vermilion borders of lips.Conclusions The double-line reconstruction helps to improve the aesthetic effect of vermilion repair on cleft lips.

AlM:To evaluate the expression of transcriptional factor lslet-1 in retina in experimental retinal neovascularization induced by oxygen.
METHODS: The murine retinal neovascularization were induced by hyperoxia exposure. The morphological observation of retinal neovascularization was performed using angiography by fluorescein dextran injection under the fluorescence microscope, and the new blood vessels were quantified after 5d in room air (17-day-old) by counting the vascular epithelial cell nuclei protruding into viteous cavity using HE stain. Realtime PCR and Western blot were used to examine retinal lslet-1 level in postnatal 7,12, 14,17 and 26d respectively.
RESULTS: A lots of new blood vessels were demonstrated in the mouse retina in hyperoxic group by fluorescein angiography and histological method. Moreover, no significant difference was found in retinal lslet-1 level in postnatal 7d between hyperoxic group and control group, but was significantly higher in postnatal 12, 14 and 17d mice compared with control mice. However, mice at postnatal 26d, expression of lslet-1 in retina decreased to normal level.
CONCLUSlON: ln processing mouse model of retinal neovascularization, sustained hypoxia retinal tissue induce retinal neovascularization by increas the expression of transcription factor lslet-1.

Objective To establish age related reference value for the new reticulocyte hemoglobin equivalent (RET-He) parameter in healthy children aged one to thirteen years. Methods Reticulocyte hemoglobin equivalent was measured by Sysmex XE-2100 after completing daily internal quality control in 424 healthy children and the outlying observations was handled afterward, Age related reference value anddistribution of RET-He level were described as the 2.5th and 97.5th centiles, and the equation regardingage related reference value was established through curve fitting methods. Results After grouping accordingto sex, the medians of boys and girls in RET-He were 31.30 pg,31.80 pg. Non-parametric test showed therewas no differences between the boys and girls. When the data from two group was integrated together, thefitted equations of RET-He were: P2.5 =-0.008X3+0.125X2 - 0.178X+26.456; P97.5= 0.021X2-0.184X+34.670(X refers to age) ; R2 were 0.85 and 0.90,respectively(P <0.05). There was statisticallysignificance for the above equations. Conclusions The reference value of RET-He in healthy children isdifferent from those in adult. The equations can be used to produce age related reference value. It could beuseful for anemia diagnosis, differential diagnosis and hematopoiesis screening at early stage.
