Objective To explore the roles of executive function deficits in adolescent violent behaviors. MethodsAccording to the findings of general state questionnaire,modified overt aggression scale and interview,93 male juvenile delinquents were randomly divided into violent antisocial group(n=47) and nonviolent antisocial group(n=46).Besides,50 male adolescents in vocational schools were served as normal controls.All the participants were subjected to Wechsler adult intelligence scale(WAIS) test,Wisconsin card sorting test(WCST),Stroop color-word test(CWT) and Tower of Hanoi(TOH) test. Results There was no significant difference in IQ between violent antisocial group and nonviolent antisocial group(P0.05).In CWT,violent antisocial group and nonviolent antisocial group had significant difference with normal control group in number of correct responses of Stroop interference effects(SIE)(P0.05).In TOH,the total time spent in violent antisocial group and nonviolent antisocial group was significantly longer than normal control group(P0.05). Conclusion There exists executive function deficits in male adolescents with unlawful acts,and violent behaviors may have a closer relationship with executive function deficits.

Objective:To investigate the role of clinical pharmacists in the therapy for a patient with acute promyelocytic leukemi-a. Methods:Clinical pharmacists participated in the treatment process of a patient with acute promyelocytic leukemia complicated with retinoic acid syndrome after tretinoin therapy. The rational treatment plan was put forward according to the literatures,the characteristics of drugs and the general situation of the patient. Results: Promising therapeutic effect was obtained,and the patient was discharged from the hospital. Conclusion:Clinical pharmacists play an active role in improving rational drug use and providing better individual-ized treatment for patients.

The cancer stem cell hypothesis posits that cancer stem cells,which are rare among the tumor cell population and share many common properties with normal stem cells,and have been positively identified and successfully isolated from some cancers,are responsible for tumorigenesis and implicated in multistage cancer progression,particularly with respect to metastasis.A better understanding may provide insights into the development of cancer stem cell-targeting therapeutic strategies.The examines what is known regarding cancer stem cells' concept,comparison with normal stem cell,potential origins,assays for isolation and their roles in metastasis.

Objective: To detect the mRNA levels of AK097082 and BC031001 encoded by psiTPTE22 gene in order to determine whether psiTPTE22 gene is the microarray-detected over-expressed gene in colon cancer and explore the role of psiTPTE22 in carcinogenesis. Methods: RT-PCR and real-time fluorescence quantitative PCR were used to detect the transcription of AK097082 and BC031001 encoded by psiTPTE22 gene in kidney, liver, stomach, lung, and colon cancer tissues and adjacent normal tissues as well as nine cancer cell lines and placenta tissues. Results: RT-PCR showed that only the mRNA of BC031001 encoded by psiTPTE22 was expressed in colon tissues. Real-time quantitative PCR assay and F test confirmed that there was no significant difference between colon cancer and adjacent normal tissues (P > 0.05). So psiTPTE22 was not the specific up-regulated gene in colon cancer detected by microarray. Real-time quantitative PCR assays also confirmed that BC031001 was over-expressed in kidney, liver, stomach, and lung normal tissues but had low expression in corresponding cancer tissues. BC031001 had no expression or weak expression in several cancer cell lines but had relatively high expression in placenta tissues. F tests found that the difference was significant in the expression level of BC031001 between kidney, liver, stomach, and lung adjacent normal tissues and the corresponding cancer tissues (P < 0.05). Conclusions: The mRNA expression of BC031001 encoded by psiTPTE22 gene has negative correlation with several kinds of cancer. Further studies are needed to reveal the mechanism underlying its down-regulation and its role in a carcinogenesis.

Objective To discussing the methods used in creating non linear developable biomechanical models of skeletal muscle.Methods One of the basic tools of the analytical approach in analytical mechanics, the principle of virtual work for deformable systems, was used to create the model. By means of method of Lagrange multipliers, the problems of constraints, such as the incompressibility of skeletal muscle, were effectively tackled. Results and Conclusion The biomechanical models of skeletal muscle has been developed. The program of this model can be used to obtain nodal displacement coordinates of given nodal coordinates and parameters.

Objective To observe the clinical, neuropathogical, neurophysiological characteristics of Charcot-Marie-Tooth disease, type 1A (CMT1A) which was similar to chronic inflammatory demyelinating polyradiculoneuropathy(CIDP).Methods The clinical data, neuroelectrophysiological changes and pathological features of sural nerve biopsy were taken from 2 CMT1A patients who were proven to be 17p12 duplication with CIDP features, and analyzed comprehensively. Results Two CMT1A cases with classical chronic course showed both subacute course and clinical manifestations similar to CIDP, however, the changes of neuroelectrophysiology and pathological characteristics of the nerve biopsy in 2 cases were different from CIDP in some way. We confirmed the chronic inflammatory demyelinating type of the CMT1A patients whom the immunotherapy was effective on.Conclusion The classical CMT1A 17p12 duplication patients who obtained immunotherapy effects might resemble CIDP both in clinical course and manifestation.

Objective The purpose of the present study was to examine the reliability and validity of the Chinese version of the impulsive-premeditated aggression scale (IPAS) in a sample of Chinese adolescents with aggression. Methods 126 adolescents completed the IPAS,Barratt impulsive scale and self-report questionnaires. In order to assess test-retest reliability, the IPAS was re-administered to 30 participants 3 weeks later.Results Item analysis showed that IPAS had satisfactory item discrimination, 6 items were excluded in the later analysis. The internal consistency of the IPAS Cronbach alpha was 0.77 and the test-retest reliability was 0.74.Exploratory factor analysis demonstrated two stable factors of aggression with good internal consistency and construct validity, the value of KMO was 0.646, the χ2 value of Bartlett test was 691.93 ( P <0.001). The confirmatory factor analysis showed that the value of χ2/df,GFI,AGFI,RMSEA were 1.42,0.874,0.837 and 0.058 respectively.The whole scale and the two secondly scales all correlated with BIS-11 and MOAS.Conclusion The results of the current study indicate that the Chinese version of the IPAS is a useful tool to subtyping aggressive behavior among adolescents, but it still need to be modified to apply in China.

Objective To assess the application value of MSCTU(multi-slice computed tomography) in upper urinary obstructive disorders. Methods MSCTU was performed in 38 patients with upper urinary obstructive patients, and we reconstituted all abscissa axis images with 3D-reconstitution technology according obstructive level to select suitable delay scan time and got CTU post-processing images. Results Among 38 patients with upper urinary tract disorders, 13 cases were urolithiasis, 5 cases congenital urinary malformations, 8 cases upper urinary tract Obstruction caused by urinary neoplasm, 5 cases were stricture of ureter caused by inflammation or tuberculosis, and 7 cases by non-uretery derived tumor. The most early of delay scan time were 8 minutes and the most late were 2 hours. Conclusion MSCTU gets advantages such as high speed scan, excellent discrimination, and aplenty post-process technique, and is of great value in application of upper urinary obstructive.
