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.

Objective:To investigate the therapeutic effect of tannins from pomegranate rind on passive Heymann nephritis ( PHN) in rats. Methods:Rabbits were with intradermal immunization for many times to obtain anti-Fx1A serum, and then PHN model in rats was established by tail intravenous injection of anti-Fx1A serum. The experimental rats were randomly divided into six groups, the nor-mal control group, model group, benazepril group, and tannins from pomegranate rind group respectively at high, medium and low dose. After the success of modeling, each rat was received intragastric administration for five weeks, and then the total of urine was collected once a week for the detection of 24-hour urine protein. At the end of treatment, serum was collected for the detection of serum albumin, blood urea nitrogen, creatinine, total cholesterol and triglyceride. The pathological changes of the renal tissue were observed using hematoxylin-eosin and Masson staining to observe the effect of tannins from pomegranate rind on PHN rats. Results:After the in-tragastric administration for five weeks, tannins from pomegranate rind could obviously reduce the level of 24-hour urine protein in PHN rats(P<0. 01), significantly reduce the levels of serum creatinine (P<0. 01), urea nitrogen (P<0. 01,P<0. 01,P<0. 05), total cholesterol (P<0. 01) and triglyceride (P<0. 01,P<0. 01,P<0. 05) in PHN rats, and increase the level of serum albumin (P<0. 01,P<0. 05,P>0. 05). HE and Masson staining results indicated that tannins from pomegranate rind could improve the pathologi-cal damage in PHN rats. Conclusion:Tannins from pomegranate rind has notable improvement for PHN in rats.

according to the difference of femoral eccentricity on the affected and healthy sides. In the reduction group (30 cases), the difference value was <-5 mm. In the normal group (87 cases), the difference value was -5-5 mm. In the increased group (45 cases), the difference value was > 5 mm. Femoral stem and femoral prosthesis type were compared among different groups. SF-12 scale score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Harris score were evaluated and compared before and after replacement. RESULTS AND CONCLUSION:Standard eccentricity of femoral prosthesis mainly accounted for 77%, 63% and 73% in the reduction group, normal group and increased group, respectively (P > 0.05). No significant difference in average eccentricity was detected in each group between the affected and healthy sides (P> 0.05). WOMAC score was significantly higher after replacement than that before replacement in three groups (P < 0.05). No significant difference in WOMAC score was found among three groups before replacement (P > 0.05). No significant differences in pain and stiffness were detected among three groups after replacement (P > 0.05), and significant differences in physical function were found (P < 0.05). The physical function was highest in the normal group. No significant difference in SF-12 scale score was seen in the three groups before and after replacement (P > 0.05). The physical ability score was elevated after replacement in the three groups (P < 0.05). Mental scores were significantly elevated in reduction and normal groups (P < 0.05). The excelent and good rate of Harris score was significantly higher in the increased group (96%) than in the reduction group (70%) and normal group (87%) (P < 0.05). These findings indicate that the increased eccentricity contributed to the pain easement after total hip arthroplasty and promoted functional recovery. The decreased eccentricity could worsen patient’s pain, and was not conducive to the restoration of joint function after replacement.

Objective To evaluate the feasibility and efficacy of catheter-directed thrombolysis (CDT) for the treatment of non-acute (history ＞ 14 days) deep venous thrombosis (DVT) of the lower extremity.Methods Clinical data of 63 patients of non-acute DVT of lower extremities treated by CDT and adjunctive angioplasty and stenting from July 2009 to August 2013 were analyzed retrospectively.Venous recanalization was graded by a thrombus score based on pre-and post-treatment venography.Follow-up was performed by Doppler ultrasound and clinical evaluation.Results A total of 63 limbs with DVT with a mean symptom duration of (22 ± 5) days were treated by a continuous combined with pulse-spray infusion of urokinase of (1.21 ± 0.69) million IU/d for (74 ± 21) hours.Significant recanalization was achieved in 77％ (48 of 63) of the treated limbs.After thrombolysis,percutaneous angioplasty was done for 15 residual lesions and stent placement was performed in 11 iliac veins and 1 femoral vein.Minor bleeding occurred in 6 (10％) patients,no patients suffered from major bleeding or symptomatic pulmonary embolism.During follow up (mean:15 ±6 months),the veins were patent in 45 (71％) limbs.15 (24％) limbs developed mild post-thrombotic syndrome (PTS),and none had severe PTS.Conclusions CDT combined with adjunctive angioplasty and stenting is safe and effective for removal of the clot burden and for restoration of the venous flow in patients with non-acute lower extremity DVT.

Objective This study aimed to study the effect of intra-brachial nitroglycerin administration via the angiography catheter on radial artery spasm in transradial percutaneous coronary intervention. Methods From patients undergoing transradial percutaneous coronary intervention (TRI) and succeeding in coronary angiography (CAG), 810 patients who needed percutaneous coronary intervention (PCI) (including Percutaneous Transluminal Coronary Angioplasty and/or stent implantation) were erolled, including 413 patients in the study group and 397 patients in the control group. When coronary angiography completed, positioned the angiography catheter over brachial artery and patients in the group received an administration of 400μg nitroglycerin via the angiography catheter. The control group received an administration of 400μg nitroglycerin via the sheath. The incidence of RAS were recored and compared. Resultes Baseline characteristics were similar between two groups. In the study group, the incidence of RAS was signiifcatively lower (18 vs. 33, P=0.021). Conclusions Intra-brachial nitroglycerin administration via the angiography catheter can prevent RAS during the insertion of guiding catheter in TRI.

Objective To study the incidence of malposition of catheter at different body positions during the operation of peripherally inserted central catheter (PICC),and then select the optimum position to increase the success rate of insertion. Methods 155 patients were randomly divided into the horizontal position group (55 cases),the semi-reclining position group (49 cases) and the sitting position group (51cases).They all used chest X-ray to conffirm the position of top end of the catheter after insertion and then comparing the incidence rate of malposition of catheter among three groups. Results After insertion,11 patients' catheters were found malposition.Among them,8 patients were in the semi-reclining position group (incidence rate 16.3％),2 patients were in the horizontal position group (incidence rate 3.6％) and only one patient was in the sitting position group (incidence rate 1.9％ ).Incidence rate of catheter malposition in the semi-reclining position group was significantly higher than other two groups. Conclusions The best position for PICC is the horizontal position.If the patient has expiratory dyspnea or need to adjust the malposition catheter,sitting position can be used.Semi-reclining position should be avoided in the operation of PICC.
