Objective To investigate the effect of puerarin and compound salvia injection on P2selectin change in patients with traumatic cerebral infarction(TCI)so as to understand the difference of their curative effect. Methods Twenty patients with TCI were randomly divided into four groups,ie,conventional treatment group,puerarin group,compound salvia injection group and combined treatment group to observe the improvement of the symptoms(Glasgow Outcome Scale,GOS)and change of plasma P2 selecfin after treatment.Results The symptoms(GOS score)and level of plasma P2 selectin in the puerarin group,the compound salvia injection group and the combined treatment group were superior to those of the conventional treatment group(P<0.05).The TCI patients had obviously higher level of plasma P2 Selectin than the healthy persons before treatment.The level of plasma P2 selectin was decreased after treatment,with better curative effect in three other groups compared with the conventional treatment group. Conclusions There is positive synergistic interaction between puerarin and compound salvia injection.Both puerarin and compound salvia injection Can decrease the level of plasma P2 Selectin to reduce the blood viscosity,inhibit the platelet activation,reduce the cerebral vasospasm and inhibit the thrombosis,as contributes to the recovery of the TCI patients.

Objective To investigate the relationship among Survivin, PTEN and the occurrence, development, soakage and prog-nesis of gastric cancer. Methods The in-situ hybrization technique, immunochemistry and TUNEL method were used to detect the expres-sion of survivin mRNA, PTEN protein and apoptotic cell. Results The positive rate of survivin expression in gastric cancer was obvious higher than that in para-cancer tissue(P <0.01). Moreover, survivin expression rate in advanced clinical stage and low differentiation gastric cancer degree.was higher, compared with para-cancer tissue (P <0.01, P <0.05). The positive rate of PTEN expression in gas-tric cancer was obvious lower than that in pars-cancer tissue (P <0.01). The positive rate of PTEN expression in advanced clinical stage and low differentiation degree of tissue in gastric cancer was lower (P < 0.01). Furthermore, survivin and apoptesis indexes manifested negative relationship in gastric cancer(r =-0.861, P < 0.01), While PTEN and apoptosis indexes manifested positive relationship (r = 0.832, P < 0.01). Conclusions Survivin could be used as a novel marker to detect gastric cancer. PTEN gene lost function, which maybe promote the origin, growth, soakage and metastasis of gastric cancer.

ObjectiveTo evaluate whether the junior high school students reared by their grandparents in 0～3 years old have more emotional and behavioral problems than their counterparts who reared by birth parents since birth. MethodsThis study was carried out to compare emotional and behavioral outcomes,using Youth Self-Report(YSR) between junior high school students reared by their grandparents in 0～3 years old and junior high school students reared by birth parents since their birth. ResultsTwo-sample test showed that the study group had significantly higher raw scores of the YSR sub-scale of somatic complaint[(2.93±2.83) vs (2.00±2.35),t=2.08,P＜0.05],social problems[(3.56±2.20) vs (2.42±1.99),t=3.15,P＜0.01],thought problems[(3.29±3.26) vs (2.16±2.29),t=2.30,P＜0.05],delinquency [(2.77±2.33) vs 2.01±1.60),t=2.19,P＜0.05] ,aggression[(7.89±6.32) vs 5.96±4.66),t=2.01,P＜0.05],externalizing problems [(10.67±8.07) vs (7.97±5.61),t=2.19,P＜0.05]and total problems [(42.64±22.76) vs (33.61±19.25),t=2.47,P＜0.05]than the comparison group. Analysis of covariance (ANCOVA) was used to control the effects of live events stress. The following analyses showed that the two groups showed no significant difference except for social problems (P＜0.05). ConclusionMany factors that affect mental health of the junior high school students. There is a significant differences in the social problems between the junior high school students reared by grandparents from infancy to the toddler stage and their counterparts. The grandparents should pay more attention to help their grandchildren developing social skills in their babyhood.

Objective To observe the alteration of Bcl-2 and Fas-L at various intervals after traumatic brain injury and study the relationship between the alteration and the post-injury interval. Method The rat brain contusion was incurred by falling impact injury, paraffin section was cut after the test group rats were killed after various survival interval and stained with antibody of Bcl-2 and Fas-L, the hemotoxylin and eosin (HE) staining was carried out meanwhile. The staining results were measured quantitatively with computer imaging analysis system. Results Positive staining nerve celis were observed around the contusion area. At 30min after injury, a few Bcl-2 could be found around the wound, the intensity and the quantity of Bcl-2 positive celis increased significantly as post-injury interval extended. At 4h, the intensity came to a peak. Then the staining decreased. Although some Fas-L positive staining celis could be found around the wound at 30min after injury, the staining increased insignificantly from Ih to 4h after the injury. After 4h, the Fas-L positive staining cell increased significantly both in intensity and in quantity as post-injury interval extended. Conclusion There is a rule that the expression of Bcl-2 and Fas-L alters along with post-injury interval extension, which will be of value in time estimation of brain injury.

Objective To explore the expression of membrane form of CD28 (mCD28) on T lymphoeytes and the serum level of soluble CD28 (sCD28) in elderly patients with primary non-small cell lung cancer (NSCLC) in order to investigate the relationship between age-related changes of CD28 and the development of NSCLC in elderly patients. Methods 63 elderly patients with NSCLC, 35 elderly patients with lung benign lesion, 30 elderly healthy donors, 30 young healthy donors, 20 young patients with lung benign lesion and 20 young patients with NSCLC were enrolled in this study. The mCD28 on T cells and the serum level of sCD28 were measured by four-color flow eytometric assay and enzyme linked immunosorbent respectively, and the relationship between CD28 and clinical characteristics of NSCLC was analysed Results The expression of mCD28 was decreased and the serum level of sCD28 was increased in elderly patients with NSCLC compared with the other groups (F= 184.25, P<0. 01 ; F= 365.40, P<0.01). The expression of mCD28 was significantly lower and the level of sCD28 was significantly higher in elderly healthy donors than those in young healthy donors and young patients with lung benign lesion (P<0. 05). There were no significantly statistical differences in expression of mCD28 and level of sCD28 between elderly healthy donors and elderly patients with lung benign lesion [(42.84±5.82)% vs. (46.09±-7.34)%, (39.38±6.02)μg/L vs. (35.84±5.02)μg/L, P>0. 05]. Logistic regression analysis showed that aging (OR=2. 432), down-regulation of mCD28 expression (OR=0. 876) and up-regulation of sCD28 level (OR= 1. 113) were the risk factors for lung cancer. In the elderly patients with NSCLC, there were significant differences in mCD28 expression and sCD28 level between stages Ⅲ-Ⅳ and stages Ⅰ-Ⅱ [(16. 51± 5.64)% vs. (24.41±8.24)%, (75.03±5.98) μg/L vs. (66.73±7.52)μg/L; t=4.497,4.794, both P <0. 01]. However, there were no significantly statistical differences among different pathological types (F=0. 609, 0. 302, both P > 0. 05). Conclusions The down-regulation of mCD28 expression and up-regulation of sCD28 level with advancing age play an important role in the oncogenesis and development of primary non-small cell lung cancer in the elderly patients.

ObjectiveTo investigate the relationship of antisocial personality disorder(ASPD) and infancy abuse.MethodsWith prospectively longitudinal research design,76 samples at infancy were initially recruited.Infancy abuse was measured by Child Protective Service records and reconfirmed by one hour family interview.56 remained samples at young adulthood were measured for antisocial personality disorder,depression,and substance abuse by utilizing Structured Clinical Interview-Ⅰ/Ⅱ (SCID-Ⅰ/Ⅱ) of DSM-Ⅳ.Longitudinal data was analyzed by multiple imputation and hierarchal regression.Results 33.9％ samples met at least one item of ASPD,38.0％ were diagnosed with substance abuse and 32.4％ with depression.Gender was correlated with ASPD symptoms (F=1.40,P =0.001 ).Infancy abuse significantly predicted ASPD (β =0.28,P=0.03 ).Further analysis demonstrated that infancy abuse was associated with ASPD with controlling substance abuse and depression (β =0.19,P =0.04 ).ConclusionInfancy abuse,with fundamental long-term effects on personality,is a risk factor for the etiology of antisocial personality disorder.The underlying mechanism might involve biological alternations.It is necessary to establish national early-life abuse monitoring and prevention system.

Objective To observe the effects of psychological supportive therapy on the activities of daily living (ADL) and depression after cerebral hemorrhage. Methods 60 cases with mild or medium depression according to 17 items Hamilton Rating Scale for Depression (HAMD-17) after cerebral hemorrhage were divided into treatment group (n=30) and control group (n=30). All of them accepted physical exercise, and those in the treatment group accepted psychological supportive therapy in addition. They were assessed with Functional Independence Measure (FIM) and HAMD-17 before and after the treatment. Results After 2 months of treatment, the score of FIM increased more in the treatment group than in the control group (P<0.001), and the score of HAMD-17 decreased (P<0.001). Conclusion Psychological supportive therapy may promote the recovery of ADL and depression for patients post cerebral hemorrhage.
