Objective:To explore whether there will be attentional bias under the condition of fear,disgust and positive emotional arousal. Methods:Totally 96 college students were selected as participants in this study,inclu-ding 60 males and 36 femalesaged 18-22 years. Affective priming videos were adopted to prime participants'emo-tion (dread,disgust,joviality),and then they named the color of the cognitive words (positive words,negative words,neutral words)as quickly and accurately as possible. Reaction time and correctness were recorded. E-prime was adopted to write the experimental program. The reaction time for neutral words was baseline. Results:The aver-age reaction time (RT)of color-naming tasks of negative words were shorter than that of neutral words after fright-ening affective priming[(648 ±118)ms vs. (743 ±124)ms,P<0. 01]. Furthermore,the average RT of color-na-ming tasks of positive words were also shorter than that of neutral after frightening affective priming[(683 ±123) ms vs. (743 ±124)ms,P<0. 05]. The average RT of color-naming tasks of negative words were shorter than that of neutral words after disgusting affective priming[(579 ±86)ms vs. (720 ±101 )ms;P<0. 01 ]. Moreover,the av-erage RT of color-naming tasks of positive words were shorter than that of neutral words after delighted affective priming[(634 ±122)ms vs. (716 ±141)ms;P<0. 01]. Furthermore,the average RT of disgusting priming group-were shorter than the frightening priming grouptowards negative information[(579 ±86)ms vs. (648 ±118)ms,P<0. 05 ]. Conclusion:It suggests that the youth perform more obvious attentional bias towards negative information after disgusting affective priming than the frightening one. Frightening affective priming could evidently induce the attentional bias on positive information.

Objective To investigate the characteristic of regional amplitude of low frequency fluctuation (ALFF) in the brain of adolescents with online game addiction during the resting state.Methods The ALFF method was employed to explore the local features of spontaneous brain activity in adolescents with online game addiction (n =26) and healthy controls (n =23) during resting-state by Resting-State fMRI Data Analysis Toolkit.Results Compared with healthy controls,adolescents with online game addiction showed increased ALFF values in the anterior cingulate cortex (ACC),left middle cingulate cortex (MCC),bilateral caudate,right pallidum,bilateral parahippocampal gyrus,and right insula.It was noteworthy that the ALFF values of the right caudate (r =0.4437,P =0.0232) and right parabippocampal gyrus (r =0.5227,P =0.0062) were positively correlated with the duration of online game addiction.Conclusion The abnormal spontaneous neuronal activity properties during the resting state were revealed in the brain regions of adolescents with online game addiction.And the abnormalities may become more significant as the disease progresses.

BACKGROUND:There was no effective method to thoroughly treat tibial bone defect and soft tissue defect. The application of Ilizarov technique solved shortening deformity, soft tissue injury and joint contracture to some degrees.
OBJECTIVE:To discuss the effects of Ilizarov external fixation on treatment of tibial bone defect and the parameter selection of Ilizarov steel ring.
METHODS:We retrospectively analyzed the clinical data of 67 patients with tibial bone defects, who were treated and fol owed up from March 2007 to January 2012. Al patients had fracture of tibia and received one-stage operation. After treatment, postoperative limb suffered from tibia osteomyelitis and soft tissue injury. Ilizarov external fixation was placed in the limb. The length of defected tibia and area of defected soft tissues were compared at 1, 3 and 6 months after external fixation and final fol ow-up. The ankle joint Kofoed score and knee joint ROM score were observed before and after external fixation. In final fol ow-up, functional recovery was evaluated in accordance with diagnosis and treatment criteria of Johner-Wruhs fracture of shaft of tibia.
RESULTS AND CONCLUSION:A total of 67 patients were fol owed up for 6 to 35 months. Bone defects in 67 cases were rebuilt and the fracture was healed, but five cases had poor healing. Among 44 cases of soft tissue injury, wound had healed in 40 cases, and wound had not healed in 4 cases. The length of tibia defect and the area of soft tissue defects were improved at 1, 3, and 6 months after the operation (P<0.05). After operation, the ankle joint Kofoed score and knee joint ROM were significantly better than those before operation (P<0.05). During final fol ow-up, the excellent and good rate of each therapeutic plan was 85%. For the tibial osteomyelitis bone defect with the merged skin defect, the trauma was smal using Ilizarov technique, which can avoid several complicated operations, shorten the time and reduce the expenses of treatment, but there were some weaknesses and limitations. The size and material of Ilizarov external fixation affect the efficiency of the fixation and postfixation adjustment.

Objective To obtain and anlysis the diffuse idiopathic skeletal hyperostosis(DISH) related miRNAs under 3-D adhesion for cell culture.Methods From January 2012 to January 2014,4 ossific ligamenta flava tissues were obtained from DISH patients and 4 normal ligamenta flava tissues were obtained from trauma patients surgically.Fibroblasts were separated by using collagenase technique and then cultured on human acellular amniotic membrane (HAAM).Each sample was identified by immunofluorescence before harvested.Total RNA was extracted and then quantified by microfluidics analysis.The small RNAs (＜300 nt) were isolated by using a YM-100 Microcon centrifugal filter.μParafloTM MiRNA microarray assay was performed using a service provider to identify miRNAs whose expression was significantly different between the two groups.Part of differential expression miRNAs were verified by qRT-PCR.Targets of miRNAs were obtained using PicTar 2005,miRanda v5,TargetScan 5.1,their function were analyzed by using Gene Ontology.Functional pathway analysis of miRNAs was performed using KEGG Pathway Analysis.TRANSFAC 7.0 public and Patser were used to get the distribution of transcription factor binding sites.Results When grown on HAAM,fibroblasts kept their morphology,distributed in the way of cluster,lived in multi-level of HAAM,and established linkage.Collagen Ⅰ and Ⅲ were tested positive in normal group cells.Collagen Ⅰ,Ⅱ,Ⅲ and Osteocalcin were tested positive in DISH group cells by immunefluorescence.In total 15 miRNAs showed differential expression,12 were up-regulated and 3 were down-regulated.The result of qRT-PCR was consistent with MiRNA microarray assay.Totally 67 target genes were predicted which participated in cell differentiation,cell adhesion,mineralization et al,and had function in regulating MAPK,Wnt,TGF-β,Focal adhesion signal pathway et al.In total 10 transcription factors were predicted in differentially expressed miRNAs.Conclusion HAAM can provide fibroblasts with 3D adhesion growth,Some differentially expressed miRNAs may participate in the pathogenesis of DISH.

Objective To observe the effect of dexamethasone(Dex)on the proliferation and os- teogenic differentiation of human marrow stromal cells(MSCs)in vitro.Methods The primary human MSCs were isolated and cultured by Ficoll seperation culture in vitro.In subcultures,human MSCs were respectively treated with dexamethasone 10~(-9),10~(-8) and 10~(-7) mol/L.The proliferation of human MSCs was measured using MTF method;cytoplasmic alkaline phosphatase(ALP)activity was measured;the osteogenic marker osteopontin (OPN)mRNA were examined by reverse transcriptase polymerase chain reaction(RT-PCR).Results The op- tical density values in cultures treated with dexamethasone 10~(-8) and 10~(-7) mol/L for 8 days were significantly lower than those in the controls(P＜0.05).Treatment of cells with Dex for 12 days led to a significant increase in cytoplasmic ALP activity(P＜0.05)in a dose-dependent manner.Dex induced OPN mRNA.Conclusion Dex inhibits the proliferation of human MSCs and dexamethasone 10~(-7) mol/L leads to a strong decrease in cell number.Dex induces human MSCs differentiate to osteoblastic cells.

Objective To investigate the instant clinical efficacy of intra-arterial infusion of fasudil combined with routine anti-vasospasm for symptomatic cerebral vasospasm (SCVS). Methods The clinical data of 21 patients with subarachnoid hemorrhage (SAH) due to ruptured aneurysm, who were admitted to authors' hospital during the period from May 2010 and February 2014, were retrospectively analyzed. The lesions included Fisher gradeⅡ(n=2), gradeⅢ (n=16) and gradeⅣ (n=3). Endovascular embolization of the aneurysm was carried out within 48 hours after the confirmation of the diagnosis with total cerebral DSA;no bleeding occurred during the operation and routine anti-vasospasm therapy was given. Within 4-9 days after the onset of the disease, all 21 patients presented SCVS. Half dose systemic heparinization, superselective intra-arterial infusion of fasudil (30 mg fasudil+250 ml saline, lasting for 30 min) were adopted. Reexamination of angiography performed at 15 min after fasudil infusion was employed, and the results were evaluated with NIHSS score by comparing the preoperative findings. Results Imaging examination performed after the treatment showed that significant improvement was obtained in 15 patients and no obvious changes in 6 patients. Clinical symptoms were remarkably improved in 11 patients, partially improved in 4 patients and remained unchanged in 6 patients. The mean NIHSS score was improved from preoperative 28.6 to postoperative 21.2. Conclusion For the treatment of symptomatic cerebral vasospasm, superselective intra-arterial infusion of fasudil is effective and safe, and it has good clinical application value.

Objective To investigate the effects of B lymphocyte-induced maturation protein-1 ( Blimp-1) on the number and function of splenic lymphocytes.Methods The mice with defective Blimp-1 in T cells were generated by cross-breeding B6.Blimp-1flox/flox mice with B6.Lck-Cre mice.The mononuclear lymphocytes isolated from spleen of T cell conditional Blimp-1 knockout (Blimp-1CKO) mice and wild type ( WT) C57/B6 mice were comparatively analyzed.Alterations of CD4+T and CD8+T cell subsets, the secre-tion of cytokines as well as the expression of C-C chemokine receptor type 7 ( CCR7 ) and Sphingosine-1-phosphate receptor 1 (S1P1) in mice from the two groups were analyzed by flow cytometry.The changes of CD19+B cell subsets were also detected.Results Compared with WT mice, the total numbers of mononu-clear cells, T and B lymphocytes were all significantly increased in Blimp-1CKO mice ( P<0.05) .The ab-solute numbers of CD4+T, CD8+T and CD19+CD5+CD1d+B cells in mice form Blimp-1CKO group were higher than those of the control group (P<0.05), however, no significant differences with the percentages of these cell populations were observed between two groups.Higher numbers and percentages of CD19+CD5+B cells were detected in mice from Blimp-1CKO group (P<0.01).The Blimp-1CKO mice showed increased secretion of IFN-γ, TNF-α, IL-17 and IL-2, but decreased expression of CCR7 on CD8+T cells as com-pared with WT mice (P<0.05).No significant differences with the changes of S1P1 were found between the two groups.Conclusion Blimp-1 played an important role in the maintenance of number, phenotype and function of T cells.Furthermore, not only T cells but also B cell subsets in mice were affected by the dele-tion of Blimp-1 in T cells.

Objective To explore the factors of relapse in alcohol-induced psychiatric and behavioral disorders.Methods103 male inpatients met with the diagnostic criteria of alcohol-induced psychiatric and behavioral disorders according to ICD-10 were enrolled.All patients were hospitalized from Wuxi Mental Center from January 2013 to August 2015.As baseline,information was obtained within all patients,and relapse was evaluated one year after discharge.The Kaplan-Meier method was used to statistically analyze the alcohol relapse time of patients with different length of hospitalization.Cox regression was used to explore the risk factors for alcohol relapse,including age,education level,marital status,family history,smoking,fixed income,number of hospitalizations,duration of alcohol intake,average daily alcohol intake,time of psychosis,psychiatric symptoms,length of hospitalization,physical condition and mental condition.Results(1)The analysis (log rank) showed that the length of hospitalization had no significant statistical differences with relapse(χ2=0.069,P=0.966).(2) The number of hospitalizations (RR=1.074,95%CI=1.002-1.151,P=0.042) and average daily alcohol intake(RR=1.035,95%CI=1.012-1.059,P=0.003) were the risk factors for relapse.ConclusionThe number of hospitalizations and average daily alcohol intake are risk factors for relapse within a year in male inpatients with alcohol-induced psychiatric and behavioral disorders.Prolonged hospital stay has no help to reduce relapse in those people.
