Aim To study the effect of halometasone in combination with scutellaria baicalensis georgi on the vitiligo mice induced by monobenzone. Methods 40% monobenzone cream was applied to induce vitiligo in C57BL/6 mice. Through the halometasone, halo-metasone and scutellaria baicalensis georgi combined with 40% monobenzone cream, the influence of halo-metasone and scutellaria baicalensis georgi on mice de-colorizing was studied. Hair decolorizing was observed with the naked eye, the skin decolorizing was observed by reflectance confocal microscopy ( RCM ) , and CD8 +T cell infiltration was tested with immunofluores-cence detection. The serum levels of interleukin-6(IL-6 ) and tumor necrosis factor-α( TNF-α) were deter-mined by enzyme linked immunosorbent assay ( ELISA) . Results Mice in model group showed de-pigmentation at both the monobenzone application part and non-application part. The halometasone group did not show significant therapeutic efficacy. In halometa-sone and scutellaria baicalensis georgi treatment group, there was less decolorization, the occurrence ratio, the scores of occurring time and size were lower compared with model group. There were fewer infiltrated lympho-cytes and CD8 +T cells. Halometasone and scutellaria baicalensis georgi group also showed that the serum levels of IL-6,TNF-α decreased. Conclusion Halo-metasone and scutellaria baicalensis georgi have thera-peutic effect on vitiligo mice induced by monobenzone.

Objective To investigate the characteristics of decision-making impairment in male patients with heroin dependence in methadone maintenance treatment(MMT). Methods A total of 45 male patients in MMT were compared with matched 32 health controls on the Iowa Gambling Task. Results Participants with anxiety or depression had to be excluded, MMT subjects were required to have negative urine toxicology screening tests.The MMT group selected more net disadvantageous cards (number of cards selected from the disadvantageous decks minus number of cards selected from advantageous decks) than health controls( (9.11 ± 19.60, -4.25 ±10.27 respectively), t=3. 884, P＜0.01). A 2(group) ×5(block) ANOVA (analysis of variance) on the cards of net disadvantageous from the gambling task revealed a significant main effect of group( F= 12.414, P＜0.01 ).The ANOVA also revealed a significant main effect of block( F=6.871, P＜0.01 ). The study indicated the totalnumber of net disadvantageous cards for MMT subjects was negative correlation to the age of initial drug use ( r=- 0. 320, P ＜ 0. 05 ). Meanwhile, methadone dose and the time of enrollment MMT did not reveal a significant main effect on decision-making biases. Conclusion The deficit of decision making for male heroin dependent patients might be attributed to the dysfunction of the ventromedial prefrontal cortex, and this effect does not resolve with abstinence, even very long term abstinence. Methadone may not get worse this impairment in male patients who have a history of heroin use during maintenance treatment intervention.

Objective To investigate the safety and clinical response of dendritic cells (DC)vaccine loaded with HLA-A2-restricted peptides MAGE-3、 Tyr、 MART-1 and GP-100 against malignant melanoma. Methods Twenty three HLA-A2 positive patients with malignant melanoma were enrolled.Peripheral blood mononuclear cells were separated into adherent cells for induction of DC loaded with four peptides. DC vaccine was administered subcutaneously once a week in inguinal region. The immunological responses and clinical responses were evaluated. Results Dendritic cell vaccination were well tolerated in all patients and there was no toxicity observed. Serum levels of IL-2, IL-12 and IFN-γincreased significantly after first vaccination and fourth vaccination. The positive rate of DTH test was 50% (5/10), and 2 fold increase of CD8+ IFN-γ+ cells were observed in 6 of 10 patients. Stable disease was observed in 11 of 23 patients, one patient had a complete metastasis regression, four patients had 50% regression of metastasis,four patients had a minor response, and disease progressed in three patients. Conclusion DC vaccines loaded with peptides MAGE-3、 Tyr、 MART-1 and GP-100 can elicit non-specific and specific immune responses, leading disease control. DC vaccine is considered one of safe and effective treatments for malignant melanoma.

Objective To investigate the attention network in patients with obsessive-compulsive disorder (OCD) and generalized anxiety disorder (GAD).Methods 31 GAD patients,31 OCD patients and 30 healthy controls (HC) were tested with attention network test.Results There were significant differences in the main effects with respect to the alerting network(15.87±5.24,26.77±4.33,34.87±3.47) (F=4.619,P=0.012)) and the executive network(114.84±9.64,122.45±5.57,96.57±5.45) (F=3.388,P=0.038) among the OCD,GAD and HC groups.The three groups did significantly differ in RT of the attention network (F=19.808,P=0.000).For the HC group,there was significant main effects with respect to cue conditions(F=29.699,P=0.000).There was a significant correlation between the executive network and Hamilton anxiety scale (r=0.351) and also a significantly negative correlation between the alerting network and Hamilton depression scale (r=-0.267).Conclusion There are attention network damages in patients with OCD and GAD,which may be involved in the impairment of emotion.

ObjectiveTo explore the attentional biases in male alcohol dependent (AD) patients and the correlations between the attentional bias and alcohol-related factors.MethodsA total of 30 recently detoxified male individuals with alcoholism were compared with 37 healthy controls ( HC ) on the Chinese Emotional Stroop Task using negative,neutral,and alcohol-related words.ResultsThe comparison between AD group( ( 1382.13 ±323.38) ms,( 1365.76 ±313.03)ms,( 1433.20 ±342.23) ms,respectively) and HC group( (797.27 ±216.97)ms,( 794.11 ± 209.41 ) ms,(799.40 ± 215.82 ) ms respectively) on the reaction time of neutral,negative and alcohol-related words were significant ( t =8.822,P ＜ 0.001 ; t =8.922,P ＜ 0.001 ; t =9.234,P ＜ 0.001 ).The error number of of the neutral and negative- related words of the patients ( ( 3.70 ± 2.56) time,( 4.23 ± 2.53 ) time)was worse than that of HC group( ( 2.11 ± 1.87 ) time,( 1.92 ± 1.82 ) time) ( t =2.939,P =0.005 ; t =4.355,P ＜0.01 ).Error number of the alcohol- related words between two groups were not significant;Its alcohol-related words attentional bias negative correlation to the age of initial alcohol use(P＜ 0.05 ),and positive correlation to continue drinking and score of self-rating depression scale (P＜0.05).Age of addiction and the score of self-rating anxiety scale enter the regression equation of alcohol-related words.ConclusionThese results demonstrate that alcoholics have attentional bias in alcohol-related words and reward-related brain regions may be associated with craving among male patients with attentional bias.
