1.Antitumor mechanism of FTY720
Journal of International Oncology 2010;37(7):520-523
Sphingosine analogue FTY720 exerts good immune suppressive effect by inducing lymphocytes apoptosis and homing, which can be used for organ transplant rejection as well as anti-autoimmune disease treatment. Recent studies have found that FTY720 plays anti-tumor potential by inducing growth arrest and apoptosis as well as inhibiting tumor metastasis.
2.Research advances in regulation of hypoxia-inducible factor-1 by camptothecin compounds
Journal of International Oncology 2008;35(10):729-731
Hypoxia- inducible factor-1 ( HIF-1) promotes tumor deterioration, invasion and metasta-sis. Treatment targeting the HIF-1 signal pathway is becoming a hot research. In addition to uniquely selective inhibition of topoisomerase Ⅰ(Topo Ⅰ) ,the recent studies show that camptothecin compounds can regulate the activity of HIF-1 through decreasing HIF-1 protein translation and have been classified as a non-selective chemical inhibitor of HIF-1.

5.Amending and evaluation of body dysmorphic disorder questionnaire
Chinese Journal of Behavioral Medicine and Brain Science 2011;20(5):466-467
Objective To evaluate the reliability and validity of body dysmorphic disorder questionnaire (BDDQ) Chinese version. Methods A total of 222 participants from a plastic surgery department were enrolled in the study by systematic sampling. They were measured with BDDQ Chinese version and interviewed with Structured Clinical Interview for DSM-]V-TR-Patients( SCID/P) to evaluate the validity. Fifty participants were assessed again after two weeks to evaluate the test-retest reliability. Results The sensitivity of BDDQ Chinese version was 100% and the specificity was 93%. The correlation coefficient of each item was between 0. 808 and 1.000(P< 0.001). Conclusion BDDQ Chinese version has fairly high reliability and validity. Thus, it can be used as a screening diagnosis tool for BDD.
6.The expression and significance of c-Ski in kidney of diabetic rats
Journal of Chinese Physician 2009;11(5):611-614
Objective To observe the expressions of c-Ski in renal tissue of diabetic nephropathy rats, and discuss its significance. Methods Wistar male rats were randomly assigned to 3 groups: Control group, diabetic group and treatment group. Rats were killed at the 16th week after experiment. Histopathologic changes,in renal tissue were observed and immunohistochemistry was performed to investigate the expression of TGF-β1, α-SMA and c-Ski. Results The expression of c-Ski had a negative correlation with TGF-β1 and α-SMA. Compared to diabetic group, the expression of c-Ski was significantly increased in treatment group. Conclusion c-Ski may be a protective factor of tu-bular epithelial-myofibroblast transformation.
7.Effect of the Yu-tone music to reduction of fear emotion
Chinese Journal of Behavioral Medicine and Brain Science 2009;18(4):354-356
Objective To explore the effect of the Yu-tone music to reduction of fear emotion. Methods 72 undergraduate students listened to Yu-tone Music or had a rest for ten minutes after elicitation of fear emotion by film clip;and measured from autonomic nerves system include skin conduction,BVP amplitude,heart rate,respiration,finger temperature and self-report subjective experience. Result 1.Compared with silence[(0.96±1.64)1/Ω,(0.85±1.73)min-1,(4.48±43.54)μV,(-5±15.37)min-1],music was associated with a significantly decreased skin resistance,respiration rate,heart rate and myoelectricity after fear emotion[(2.04±2.22)1/Ω,(0.09±1.79)min-1,(8.47±26.24) μV,(1.57±20.88) min-1,P <0.01,P <0.01,P <0.01,P <0.05]; 2.Compared with silence[(-0.37±2.71)μV, (0.13±1.16) ℃ ],music was enlarged BVP amplitude and skin temperature[(-0.53±3.8)μV,(-0.02±0.87)℃],but there was no significant difference( P >0.05,P >0.05).Conclusion Music advance the restore of negative emotion,and reduce excitability of the sympathetic and improve function of the parasympathetic nervous systems. Simultaneously,music significantly enhance the feelings of happiness as well as quietness of positive emotion.

Chinese Journal of Behavioral Medicine and Brain Science 2009;18(1):54-56
ObjectiveTo explore the relationship of organizational factors with occupational burnout among doctors. Method740 doctors were assessed by CMBI, Job Demands and Decision Latitude scale, Distributive and Procedural Justice scale, Cross-Culture Role Conflict, Ambiguity, and Overload scale, Work Interference With Family and Family Interference With Work scale, Social Support scale. ResultsHierarchical multiple regression indicated that 27.8% variance of doctors' Emotional Exhaustion(EE), 36.8% variance of Depersonalization(Dp), 21.0% variance of Reduced Personal Accomplishment(RPA) were explained by Organizational factors. Work Interference with family, role conflict, work-family conflict, distributive justice and workload can significantly predict EE(Standardized β was 0.204, 0.102, 0.249,-0.109,0.093); Family interference with work, role ambiguity, family support, procedural justice and workload can significantly predict Dp(Standardized β was 0.506,0.192,-0.122,0.105,-0.068); Role ambiguity, family support, job control, work Interference with family and superior support can significantly predict RPA(Standardized β was 0.245,-0.179,-0.172,-0.106,-0.069). ConclusionOrganizational factors have significantly effect on doctor's burnout, especially work-family conflict and role character.

Chinese Journal of Behavioral Medicine and Brain Science 2009;18(2):161-163
Objective To acquaint the condition of learning burnout of medical students and to explore the relationship of learning burnout with professional commitment and social support. Methods 610 medical students were evaluated with Learning Burnout Scale, professional commitment scale and social support scale. Results ①In general, learning burnout index of medical students was 2.84±0.49; in terms of gender difference, male students [(2.83±0.65) and (3.08±0.61)] were higher than females[(2.70±0.63) and (2.96±0.60)] at the level of emotional turndown and behavioral unsuitableness, the difference was statistically significant( P <0.05); in terms of grades, medical students'learning burnout of different grades was significant( F =4.244,P <0.01); there was no difference in profession. ②Learning burnout was significantly negative correlation with professional commitment and social support( P <0.01). ③Multiple regression analysis showed that affective commitment and family support had significant predications on learning burnout of medical students( P <0.01). Conclusion Medical students'learning burnout level is comparatively high, learning burnout closely relates to professional commitment and social support.
10.A study of coagulation and fibrinolytic system changes in liver cirrhosis patients with and without portal vein thrombosis
Chinese Journal of Postgraduates of Medicine 2009;32(7):11-13
Objective To investigate the coagulation and fibrinolytie system changes in liver cirrhosis (LC) patients with and without portal vein thrombosis (PVT). Method Twenty-six cases of LC with PVT (PVT group) and 61 eases of LC without PVT (control group) were chosen. Platelet(Pt), prothrpmbin time (PT), activated partial thromboplastin time (APTT), fibrin (Fib), D-dimer, tissue plasminogen activator (t-PA) and plasminogen activator inhibitor-1 (PAI-l) were determined. SPSS 11.5software was used for statistic analysis. Results In PVT group, the average level of D-dimer was (0.97±0.53 ) mg/L,signifieantly higher than that in control group (0.61±0.40) mg/L. No significant difference was found between the two groups in Pt PT, APTT, Fib, t-PA and PAI-1. PT and APTT were progressively prolonged from Child-Pugh grade A to B and then to C. Fib was progressively decreased from Child-Pugh grade A to B and then to C. Decreased Pt and increased t-PA, PAI-1 were found in LC patients, but had no sighifieant difference. Conclusions The changes determined of coagulation and fibrinolytie system in patients with LC are abnormal. The average level of D-dimer is higher in LC patients with PVT than that in LC patients without PVT. D-dimer may be a helpful tool to rule out the presence of an underlying PVT in LC patients.
