Objective:To evaluate the efficacy and safety of microporous polysaccharide hemispheres(MPH)in control of homostasis on residual liver after hepatectomy. Methods: 60 patients undergoing hepatectomy were randomized to four groups standard group,test group Ⅰ,test group Ⅱ,and control group. Patients in standard group(15 patients)were treated with routine surgical technique to achieve homostasis.In test group Ⅰ(15 patients)the MPH combined with absorbable haemostat were used as hemostatic agents while only the MPH was used in test group Ⅱ(15 patients). The other 15 patients were given absorbable haemostat as control group. The hemostasia time, the amount of blood transfusion during operation and three days after operations were evaluated, the other factors (ALT, Alb, biliary, PT)were also evaluated. Results: In the standard group, hemostasia time was (2.98?1.05) min; the blood transfusion amount was (400?200) ml during operations and (400?200) ml three days after operations; the amount of drainage was (350?100) ml. In the test group Ⅰ, hemostasia time was (3.10?0.85) min; the blood transfusion amount was (200?0) ml during operations and (200?100) ml three days after operations; the amount of drainage was (200?100) ml. In the test group Ⅱ, hemostasia time was (3.20?1.52) min; the blood transfusion amount was (200?200) ml during operations and (200?0) ml three days after operations; the amount of drainage was (150?100) ml, and while in control group, the corresponding results were (5.22?1.82) min, (600?200) ml, (400?200) ml, (400?150) ml, respectively. Satisfactory bleeding control was achieved in 5 patients with routline surgical technique, there was no significant diffterence among them. The incidence of hemostasis in control group (33%)was significantly lower than that in standard group(80%) and all test groups(73.3%, 66.7%, respectively). No hemostatic complications were noted in either group. Conclusion: MPH provides rapid, effective and safe hemostasis after hepatectomy, which can be applied in hepatectomy.

Objective To explore the mediation effect of self-esteem on the relationship between perfectionism and depression in college students.Methods Totally 292 college students completed Frost Multidimensional Perfectionism Scale (FMPS),Hewitt Multidimensional Perfectionism Scale (HMPS),Slaney Almost Perfect Scale-Revised (APS-R),Rosenberg Self-esteem Scale (SES) and Beck Depression Inventory (BDI).Results Maladaptive perfectionism was positively correlated with depression (r =0.54,P ＜ 0.01),and negatively correlated with self-esteem (r =-0.55,P ＜ 0.01).Adaptive perfectionism was not correlated with depression (r =-0.09,P ＞ 0.05),and was positively correlated with self-esteem (r =0.36,P ＜0.01).Self-esteem partially mediated the association between maladaptive perfectionism and depression.The partial mediation effect was significant (P ＜0.05).The mediation model fitted the data well (GFI =0.986,CFI =0.988,NFI =0.981,TLI =0.970,RMSEA =0.075).Conclusion Self-esteem has partially mediating effect on perfectionism and depression.

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.

Abstract: An enriched environment refers to conditions that facilitate sensory, cognitive, motor, and social stimulation. Behavioural,cellular and molecular studies have revealed significant effects of enriched environments on rodents and other species. Post-ischemic housing in an enriched environment improves functional outcome, modifies gene activation, induces alterations in the expression of N-methyl-D-aspartic acid (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunits, increases dendrite branching and number of dendritic spine in pyramidal neurons in layers II/III in the contra-lateral cortex, induces structural changes in synaptic junctions. Furthermore, it alters lesion-induced progenitor cell differentiation and interacts with necrotic grafting. The idea of environmental enrichment has been applied to clinical stroke rehabilitation and is getting more and more attention. This review will summarize experimental effects of enriched environment on post-ischemic rehabilitation and the clinical application of enriched environment in stroke rehabilitation.

Objective To screen the risk factors of esophageal-gastric fundus variceal bleeding,in order to provide a more economical and less invasive method for predicting esophageal-gastric fundus variceat bleeding. Methods A total of 168 diagnosed liver cirrhosis patients accompanied with ascites and 60 cases of liver cirrhosis patients with primary hepatic carcinoma were enrolled. Followed up for one year, the esophageal-gastric fundus variceal bleeding was observed and analyzed with statistic methods. Results Unconditional single factor logistic regression model analysis indicated that albumin level of ascites, serum-ascites albumin gradients (SAAG), platelets, activated partial thromboplastin time (APTT), portal vein width, length and thickness of the spleen were independent risk factors,age and serum albumin were protective factors. Multifactor analysis indicated SAAG, APTT, and portal vein width were the independent risk factors, OR was 3.559 , 2.468 and 2. 608 respectively.After building receiver operating characteristic curve, the best SAAG cut-off value was 18.50 g/L, of which the sensitivity was 96.3％ and specificity was 56.3％. Conclusion SAAG has good value in predicting esophageal-gastric fundus variceal bleeding.

Objective　To investigate the role and clinical significance of proglumide (PGL) in gastrin-stimulating cell proliferation on human colon cell line SW480.Methods　Effects of proglumide on the viable cell count (A value), IP3 (CPM value), ［Ca2＋］i and PKC activity of human colon cell line SW480 were evaluated in vitro by MTT assay, 3H-myo-inositol incorporation, fluorescence measurements and γ-32P-ATP incorporation. Results　The results showed that A value of PGL＋PG group is lower than that of PG or control group (P＜0.01 in both groups); The concentration of IP3 or ［Ca2＋］i in PGL＋PG group is lower than that in PG group (P＜0.05). Conclusion　These results indicate effects of proglumide may be through the phosphoinositide signalling pathway on gastrin-stimulating cell proliferation in human colon cell line SW480. It will provide an experimental evidence for antisingnal transduction therapy for patients with colon cancer.

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.
