AIM:To investigate the validity of Rorschach inkblot method (RIM) in personality research by calculating the correlation of RIM with 16 personality factor questionnaire (16 PF).METHODS: Totally 70 undergraduates participated in the examination with RIM and 16 PF, then the correlations of all the variables of two measuring techniques were calculated. Standard score of comprehensive system was used in RIM.RESULTS: Some important Rorschach variables were correlated significantly with 16PF factors, and the correlations are consistent with their meaning. Some variables correlated with 16PF factors but were irrelevant in meaning.CONCLUSION: The results support the validity of RIM in personality study, and they also demonstrate that comprehensive system cannot well annotate RIM, but the meaning of some variables should be further researched.

BACKGROUND: Item response theory (IRT) is widely used in the westem world, but its use for non-cognitive measurement has been very limited in China. It is necessary to explore whether IRT is applicable in non-cognitive settings and find the optimal model.OBJECTIVE: To find the optimal IRT model for self-report questionnaire analysis with the instance of emotional competence scale (ECS) and compare the effectiveness of different models in light of model data fitting and the volume of information provision.DESIGN: A comparative study of different psychometric models tested with the same data set.SETTING: Shandong Laiwu Vocational and Technical College; Department of Psychology, Liaoning Normal University.PARTICIPANTS: Totally 617 college students of Shandong Normal University (311 males and 306 females)and 564 senior high school students of the 17 Laiwu High School (283 males and 281females) participated in the study during May 2004.METHODS: Emotional competence scale (ECS) was adopted for psychometric measurement for 5-point Likert-type items. The scale was divided into 9 subscales, namely impulse control, empathy, persistency, interpersonal intimacy, social skills, emotional regulation, emotional stability, sense of responsibility, and self-confidence. One-parameter, two-parameter and three-parameter logistic model and grade response model were used for analysis of the 9 subscales, followed by goodness of fit test (analogous to Chi-square test) and comparison of the measurement precision (reliability)of the three models.MAIN OUTCOME MEASURES: Log-likelihood ratio, average χ2 statistics and average volume of information when one-parameter, two-parameter and three-parameter Logistic model.RESULTS: Totally 1 220 questionnaires were handed out and 1 181 with valid answers were obtained. Comparison of the 3 logistic model showed that the two-parameter logistic model had the least log-likelihood with the least items whose mean square residual error were greater than 2, and the volume of test information was greater than that provided by one-parameter model and no less than the three-parameter model. Therefore, the two-parameter logistic model was the best for 2-point scoring model. But the measurement precision of two-parameter Logistic model was lower than that of multi-grade response model.CONCLUSION: When 2-point items are adopted in self-report questionnaire, 2-parameter logistic model can be applied but not 1- or 3-parameter Logistic models. But when the questionnaire uses items that have more than 2 response grades, the measurement precision can be better than that of 2-point data. Merge of the options for the items may result in lowered measurement precision.

When a section is divided into two or more sections in hospital,patients must be assigned to the new section along with all medical data.With SQL commands,data is transferred according to the patient's section division.This method is also fit for the case that the section is divided while the nursing unit is not.

Objective To study the audiometry and otoacoustic emissions in patients with posterior circulation ischemia(PCI) .Methods Forty patients treated by neurologists were selected as the experimental group who re_ceived pure tone audiometry ,tympanometry ,otoacoustic emissions (OAE) and distortion products otoacoustic emis_sions (DPOAE) examinations .Thirty healthy objects were chosen as the control group .The data from the PCI groups and the control group were compared using the SPSS 14 .0 software .ResuIts The difference in pure tone thresholds across 125 to 8 000 Hz between the PCI group and the control group was not statistically significant (P>0 .05) .In the PCI patients ,the prevalence of TEOAE was only 47 .5% ,significantly different from that of in the control group .The prevalence of DPOAE at 0 .5~8 kHz were between 57 .9% ~77 .6% in PCI patients ,and the amplitudes of DPOAE were reduced significantly (P<0 .05) .ConcIusion Cochlear damages can occur to patients with PCI ,especially in the high frequency range .These results suggest that OAE can be used as an important diag_nostic test for patients with PCI ,and might be helpful for the location diagnosis of PCI .

Objective To investigate the intentions of pension mode of the aged in the unban and rural of Xi' an,and analyze the possible influential factors in old persons' choices of pension modes.Methods The purposive sampling method was used to survey the old persons about their pension intentions by questionnaire,and the collected information underwent statistical analysis.Results Among 317 old persons aged from 60to 91 years old investigated in the study,145 cases were from urban and 172 from rural area.Most old people intended to choose self-pension mode,family pension mode and community pension mode.Only few people chose institution pension mode.Their favorite pension mode was family pension mode,and institution pension mode was the last one to choose for old people.Community pension mode should be developed mostly in their opinion,and self-pension mode must be reduced.Some essential variables had significant influence on their choices of pension models,such as living in urban or rural,occupation,age,marriage,the incomes per month,family support,habitancy and so on.The result of logistic analysis showed that some other variables had no obvious influence on their pension intentions.Conclusions Old people in Xi'an prefer family pension mode mostly.Community pension mode is the one which has a good developing prospect.Social pension mode need to be intensified.

AIM:To observe the effect of parenteral nutrition(PN)in the feeding of premature infants.METHODS:Seventy five premature infants were randomly assigned into three groups.The control group supplied glucose combined with minimal enteral nutrition and assisted with nonutrition sucking.In treatment groups:the no-fat emulsion PN group supplied amino acids and glucose combined with minimal enteral nutrition and assisted with nonutrition sucking,and the fat emulsion PN group supplied fat emulsion,amino acids and glucose combined with minimal enteral nutrition and assisted with nonutrition sucking.After 1 week,the weight,the state correlated biochemical indicator and complications were detected.RESULTS:Both of the no-fat emulsion PN therapy and the fat emulsion PN therapy could promote weight gain and lessen complications,and the clinical application was comparatively safe.CONCLUSION:The PN can improve growth and development of premature infants and elevate the clinical therapeutic efficacy.

Objective To study the factors which affect the functional restoration of the elbow for adults with supracondylar or intercondylar fractures of the humerus treated with open reduction and internal fixation. Methods 22 patients with supracondylar or intercondylar fractures of the humerus were treated with open reduction and internal fixation from January, 1999 to December, 2004. They were followed up for an average of 30 months and complete clinical data were kept. The function of the elbow was evaluated with the Mayo elbow performance index. The relationship between the results and the factors —initial time of postoperative rehabilitation, fracture classification, operative approach and interval from injury to operation —were analyzed with cumulative logistic regression model of SAS software V8.2 (SAS institute, Cary, North Carolina). Results Of the 22 cases, 7 were excellent, 9 good, 5 fair and 1 poor. The excellent and good rates were 72.7%. And the odds ratio estimates of the 4 factors were 0.786, 0.299(B/A)0.221(C/A), 1.038, 0.197 respectively. Conclusions The initial time of postoperative rehabilitation, the fracture classification and the interval from injury to operation affect the functional restoration whereas the operative approach does not. Early operation, anatomical reduction, stable fixation and early rehabilitation will help improve the functional restoration.

As an important transmembrane protein in brain microvascular endothelial cells tight junction, occludin plays important roles in regulating and maintaining blood-brain barrier permeability. Its abnormal expression can increase blood-brain barrier permeability. In order to provide some theoretical supports for the roles of studying occludin intensively in the mechanisms of blood-brain barrier permeability-related diseases and targets for pharmacological intervention, this article reviews the roles of occludin in the molecular composition and functional maintenance of blood-brain barrier tight junction, as well as the changes of cerebral microvascular permeability during hypoxia.
