Electric fields have special biological effects for its heating and non-heating effects. Heating effects are about the technology of radio frequency and microwave thermotherapy while non-heating effects are alternating electric field and pulsed electric field. These electric fields have significant effects for tumor treating.

Girdin protein is a kind of actin binding protein,which has the complex molecular structure and takes part in a variety of signaling pathways related with causing cancer.The biological characteristics of Gir-din protein have close association with the proliferation and invasion of malignant tumor.Recent studies have shown that Girdin protein is closely related with occurrence and progress of breast cancer.Girdin protein expres-sion in breast cancer cells can not only promote the progress of breast cancer,but also affect the lymph node me-tastasis and prognosis.Therefore Girdin protein is expected as an independent biomarker to provide a new direc-tion for breast cancer treatment.

Objective To observe the effect of transperineal injection of botulin A toxin on patients with detrusor-external sphincter dyssynergia caused by spinal cord injury. Methods Transperineal injection of botulin A toxin were performed in 6 patients with spinal cord injury (3 with cervical spinal cord injury and 3 with thoraco-lumbar spinal cord injury) complicated by detrusor-external sphincter dyssynergia.55 U of botulin A toxin was injected twice separately. The interval between 2 injections was 3 days.Before treatment, the residual volume of urine after voiding was determined and the maximum urethral pressure was measured by urodynamic testing.One month after treatment the examination mentioned above was repeated. Results The decrease in residual volume of urine was (133.3?70.9)ml.The decrease in maximum urethral pressure was (35.4?25.8)cmH 2O(both P

BACKGROUND:Previous studies have found that the expression level of miR-486 in glioma stem cels (CD133+) is significantly down-regulated compared with that in glioma non-stem cels (CD133-), but the effect of down-regulation of miR-486 on CD133+ cels remains unclear . OBJECTIVE: To explore the effect of miR-486 on CD133+ cels. METHODS:CD133+ glioma stem cels and CD133- glioma cels were separated from U87 cels by flow cytometer. miR-486 overexpression glioma stem cels were constructed by lipofection transfection. RESULTS AND CONCLUSION:After sorting and purification, the content of the CD133+ fraction was enriched up to 83.5%. The expression level of miR-468 in CD133+ glioma stem cels was obviously down-regulated compared with that in CD133- glioma cels. CD133+ glioma stem cels overexpressing miR-486 were fabricated successfuly. Results from in vitro experiments showed that miR-486 overexpression could dramaticaly decrease the proliferation of glioma stem cels, induce a cel cycle arrest in G1/S phase for CD133+ glioma stem cels and promote cel apoptosis. These findings suggest that miR-486 can be a suppressor of glioma stem cels, which offers a novel potential therapeutic target for glioma stem cels and human glioma.

Objective:To observe the efficacy of Chuankezhi injection combined with budesonide and formoterol fumarate powder for inhalation in the treatment of chronic obstructive pulmonary disease ( COPD) . Methods:Totally 120 patients with COPD were ran-domly divided into two groups:the observation group inhaled budesonide and formoterol fumarate powder for inhalation combined with intramuscular injection of Chuankezhi injection, and the control group inhaled budesonide and formoterol fumarate powder for inhala-tion. The treatment course was 28 days. The pulmonary function indices [ FEV1% expected value, FEV1 /FVC, 6 min walking dis-tance (6MWD)], the times of acute exacerbation and the adverse drug reactions during the treatment were observed and compared be-tween the two groups. Results:After the treatment, the lung function and 6MWD were improved in the two groups, and the improve-ment of FEV1% expected value in the treatment group was more obvious than that in the control group [(59. 7+12. 1)% vs (49. 8+11. 3)%, P<0. 05]. The number of patients with at least once of acute exacerbation was significantly reduced in the treatment group when compared with that in the control group (35% vs 62%, P<0. 01). The incidence of adverse drug reactions in the two groups showed no significant difference. Conclusion:Chuankezhi injection combined with budesonide and formoterol fumarate powder for in-halation can notably improve the lung function in the patients with COPD and reduce the times of acute exacerbation without effect on the incidence of adverse drug reactions.

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.
