Objective To observe the influence of wind-dispelling therapy on therapeutic effect of blood-cooling and kidney-tonifying herbs for chronic idiopathic thrombocytopenic purpura(CITP),and to investigate its immunoregulatory effect.Methods Forty-two CITP patients were randomized into 2 groups:the treatment group(N=22) received therapy of dispelling wind,cooling blood and tonifying kidney,and the control group(N=20) received therapy of cooling blood and tonifying kidney.Six weeks constituted one treatment course,and the treatment lasted 3 courses.Serum interleukin 2(IL-2),soluble IL-2 receptor(sIL-2R),Fas protein,Fas-L protein,and platelet-associated immunoglobulin G(PAIgG) levels and lymphocyte subtypes were compared before and after treatment.Results In the treatment group,14 patients were clinically cured,5 markedly effective,2 effective,1 ineffective and the total effective rate was 95.5%;in the control group,8 patients were clinically cured,4 markedly effective,3 effective,5 ineffective and the total effective rate was 75.0%.The therapeutic effect in the treatment group was superior to that in the control group(P

AIM:To investigate the effect of TSM tablet on rat' s atherosclerotic model' s endothelial cell and explore the mechanism of it.METHODS:Fifty Wistar rats were randomly assigned into five groups:control group,model group,Simvastatin group,TSM high group,TSM low group.All groups were fed with high fat diet and vitamin D_3 except for control group to set up atherosclerosis model.After 12 weeks we detected circle endothelial cell,angiotensin Ⅱ and electron microscopy morphology of arteries.RESULTS:Level of circulating enthelia cell(CEC)and Ang Ⅱ in model rats were significantly higher.TSM can reduce level of the CEC and Ang Ⅱ.Model group rat' s artery endothelial cells were severely damaged under electron microscopy;rat's artery endothelial cells in TSM group were basically intact and its internal elastic membrane was unbroken on it thickness was even,without significant lesion.CONCLUSION:TSM by reducing the number of CEC,the level of Ang Ⅱ used for experimental atherosclerotic endothelial cell in rats has the protective effect.

BACKGROUND: A better understanding of medical students' attitude towards living liver donation in China would be of importance significance in the development of organ transplantation. OBJECTIVE: To investigate the medical students' attitude toward living liver donation in China and to analyze the factors that affect such an attitude.METHODS: A random sample of 250 medical students was taken and stratified by grades with 50 students in each grade. The attitude was evaluated by a modified psychosocial questionnaire from Spain. The questionnaire was completed anonymously and was self-administered. A bivariate analysis including the Student's t test and the Chi-square test was performed using SPSS software. RESULTS AND CONCLUSION: The questionnaire completion rate was 97.2% (n=243) for the medical students. Among the respondents, only 13.2% (n=32) of them were in favor of unrelated living liver donation. Another 66.3% (n=161) were only in favor if the donation was for a relative. Of the rest, 6.6% (n=16) did not agree with living liver donation, and the remaining 14.0% (n=34) were undecided. The factors related to this attitude were the decision of donating the organs of a family member (P=0.002), attitude toward deceased donation (P=0.000), a willingness to receive a donated living liver organ if one were needed (P=0.000), attitude toward living kidney donation (P=0.000). The medical students have a favorable attitude toward living liver donation in China. The students' attitude toward other types of organ donation and the willingness to accept living donated liver influence their attitude toward living liver donation. There is a great lack of education about the organ donation and transplantation for the medical students in China and more education programs should be incorporated into their traditional curriculum.

Objective:To develop a Child School Refusal Behavior Rating Scale(SRBQC)and examine its reliabilities and validities. Methods:Based on literature review,interview,and open-ended questionnaire,124 origi-nal items were developed. Totally 573 students were recruited to complete the test version. After item and explorato-ry factor analysis,the formal scale-SRBQC was got. Totally 946 students were tested with formal version for further confirmatory factor analysis,internal consistency reliability and composite reliability. The criterion validity was test-ed with the Social Anxiety Scale for Child (SASC). Totally 41 students were retested for test-retest reliability with 2 weeks interval. Results:The formal version of SRBQC included 19 items. Exploratory factor analysis generated 5 factors which account 59. 793% of the variance in all,the results of confirmatory factor analysis showed that SR-BQC had a good construct validity (χ2 =329. 51,df=142,χ2/df=2. 32,CFI=0. 97,GFI=0. 93,IFI=0. 97,NFI=0. 95,NNFI=0. 96,RMSEA=0. 05,SRMR=0. 05). The SRBQC scores were positively correlated with the SASC scores (r=0. 18-0. 34,Ps<0. 05 ). The Cronbach coefficients were 0. 87 for the total questionnaire and 0. 55 -0. 78 for the 5 factors. The test-retest reliabilities were 0. 84 for the total questionnaire and 0. 66 -0. 78 for the 5 factors. Conclusion:The reliability and validity of the School Refusal Bevior Questionaire for Children(SRBQC) meet the needs of psychometrics.

Objective To investigate the effects ofZhenqi-Fuzheng capsule combined with highly active antiretroviral therapy (HAART) the Thl/Th2, Tcl/Tc2, and CD4+ T lymphocytes in patients with advanced AIDS.Methods A total of 70 patients with advanced AIDS were randomly divided into a treatment group and a control group, with 35 patients in each group. The treatment group was treated withZhenqi-Fuzheng capsule combined with HAART, while the control group was treated with HAART only. The patients in both groups were treated for 24 weeks. The Thl, Th2, Tcl, Tc2 and CD4+ T lymphocytes in peripheral blood were detected by flow cytometer.Results After treatment, the ratios of Th1/Th2 (6.27 ± 0.70vs. 5.39 ± 0.64;P<0.05) and Tcl/Tc2 (10.70 ± 0.68vs. 10.16 ± 0.85;P<0.05) in the treatment group showed significantly higher than those in the control group. The CD4+T lymphocytes after the treatment in both groups showed significantly increased than that before the treatment (treatment group: 289.2 ± 101.5/mlvs. 121.1 ± 77.5/ml,P<0.01; control group: 231.6 ± 97.6/mlvs. 118.9 ± 76.2/ml,P<0.01). The CD4+T lymphocytes in the treatment group showed significantly increased than that in the control group after the treatment (P<0.05).ConclusionsZhenqi-Fuzhengcapsule combined with HAART may regulate the Thl/Th2 and Tcl/Tc2, and increase the CD4+ T lymphocytes in patients with advanced AIDS.

Objective To study the effect of rimonabant, cannabinoid receptor 1(CB1) antagonist, on the expressions of CB1 andα-smooth muscle actin (α-SMA) in C57 mice with experimental hepatic fibrosis, and their mechanisms in liver fibrosis progression thereof. Methods Thirty C57 mice were randomly divided into three groups, normal control group, mod-el control group and model+rimonabant group, 10 mice for each group. The mouse model of experimental hepatic fibrosis was induced by intraperitoneal injection with 10%CCl4 for two weeks. The normal saline was delivered by gavage daily in normal control group and model control group. Rimonabant was given to mice in model+rimonabant group. Mice were sacri-ficed at the end of eight weeks. Samples of liver tissue were collected. The expressions of CB1 andα-SMA in liver tissue of mice were observed by immunohistochemical staining. The score of fibrosis stage (S) in liver tissue was also analyzed. Re-sults The positive expressions of CB1 andα-SMA and the score S were significantly higher in model control group and model+rimonabant group than those in normal control group (P<0.05). The positive expressions of CB1 andα-SMA and the score S were significantly lower in rimonabant group than those in model control group (P<0.05). There were positive corre-lations in CB1,α-SMA and S scores between normal control group, model control group and model+rimonabant group (P<0.05). Conclusion The activation of CB1 can promote the formation of liver fibrosis. The anti-fibrotic effect of rimonabant, CB1 antagonist, related with the inhibiting of the proliferation and activation of hepatic stellate cells (HSC), and the inhibit-ing of the expression of CB1.
