Objective: To study shame of college student through phenomenological method. Method: 147 college students (male 53, female 94, average age 20.2) were involved. Each subject was asked to describe his/her personal shame experience, which was rate on phenomenological dimensions. Experience of Shame Scales (ESS) was used either. Result: The finding from phenomenological rating was in accord with the theory of “self orientation". Students with stronger shame proneness showed tendency to attribute negative events to him/herself. Conclusion: Shame is an acutely painful experience that involves a marked self-focus (self oriented) emotion. Shame proneness tended to have stronger sense of worthlessness and powerlessness and have much more strategies of denying and escaping in hard situations.

Objective:To study the effects of group counseling which based on interpersonal activities and aimed at the college students with computer gaming addiction in China.Methods:Seventeen college students with computer game addiction were chosen as the experimental group,and 10 college students from another college were chosen as the control group.The two groups had no difference in the scores of Computer Gaming Addiction Invention(CGAI)and several other scales before group counseling.There were a pre-test and a post-test separately set when the group counseling was started and finished,focused on CGAI and negative emotions and cognitions.Results:In post-test,the score of CGAI in experimental group was significantly lower than that in control group[(92.6±16.7)vs.(105.9±13.0)] and lower than that in pre-test(98.9±16.4)by analysis of covariance(Ps<0.01).The scores of Beck Depression Inventory(BDI),Self-Rating Anxiety Scale(SAS),and the negative cognition of oneself in socical settings in experimental group were also lower than those in control group [(6.4±7.9)vs.(13.5±5.6),(39.7±6.4)vs.(49.9±10.3),(15.1±4.3)vs.(19.9±3.0),Ps<0.01],while the score of Rosenberg Self-Esteem Scale(SES)was higher than that of the control group [(29.3±2.9)vs.(24.6±4.8),P<0.01].Conclusion:Group counseling based on interpersonal activities has obvious effects on the college students with computer gaming addiction.

Objective To investigate the effects of miR-200c on proliferation and apoptosis of tongue squamous cell carcino-ma (TCCS)Tca8113 cells.Methods The mimics of miR-200c were transfected into Tca8113 cells using liposome.The Tca8113 cell proliferation was detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)assay.The flow cytometry as-say was used to determine the cell cycle and the apoptosis rate of Tca8113 cell.The protein expression levels of Bcl-2 and Caspase-3 in Tca8113 cell was detected by Western-blot.Results The 20,40,80 nmol/L miR-200c mimics groups inhibited the growth of Tca8113 cells,the difference compared with the control group showing statistical significance(P <0.05).The greater the miR-200c mimics concentration and the longer duration of action,the more significant the inhibition effect(P <0.05).After 48h transfecting by miR-200c mimics,the Tca8113 cells were arrested in the G0/G1 phases of cell cycle,and the apoptosis rate of the miR-200c mim-ics groups was significantly increased,the difference compared with the control group showing statistical significance(P <0.05);Western blot verified that the expression amount of Bcl-2 protein in the 20,40,80 nmol/L miR-200c groups was significantly lower than that in the control group,while the expression amount of Caspase-3 protein was significantly higher than that in the control group(P <0.05).Conclusion The overexpression of miR-200c might inhibit the proliferation of Tca8113 cell and induces their ap-optosis.

ObjectiveTo investigate synergistic effect of donor livers blocked by recipient blood serum (RS) and cobra venom factor (CVF) treatment to inhibit hyperacute rejection (HAR) happened in liver xenotransplantation.MethodsThe SD rat blood serum was prepared for pre-perfusing the donor livers before experiment.24 pairs of guinea-pig (GP) and Sprague-Dawley (S.D.) rats were choiced respectively and pair-matched between GP donor and rat recipient randomly.Before transplantation,donor livers of GPs were pre-perfused by 0.5％ SD rat serum.Paired animals were divided into 4 groups randomly such as donor liver perfused by RS,recipient treated by CVF,RS+ CVF performed and Ringer solution as a control.The orthotopic liver xenotransplantations was performed with two-cuff technique.The survival time and liver function of recipients,morphological and pathological changes of rat livers were observed.ResultsThere was no piebaldism change on the recipient liver from experimental group.The survival time of recipients from RS+CVF group [(161.5±30.9) min]was longer than that of control[(45.2 ± 13.9) min] and CVF[(125.2 ± 25.5) min] or RS groups [(88.1±19.7) min] (P＜0.05).The ALT in serum of recipients from RS+CVF [(63.2±13.9)U/L]was lower than that from congtrol group [(126.1±23.3)U/L](P＜0.01) and CVF group [(79.9±18.1)U/L](P＜0.05) or RS group [(106.1±19.3)U/L](P＜0.01) The histological damages including thrombosis,interstitial bleeding and edema of recipient liver from RS+CVF group were alleviated markebly than that of other groups (P＜0.05).ConclusionThere was a synergistic effect to inhibit HAR happened in liver xenotransplantation by blocking the donor liver with recipient blood serum and CVF treatment significantly.

ObjectiveTo investigate a new way to prevent hyperacute rejection (HAR) during liver xenotransplantation through blocking the xenograft with recipient blood serum before transplantation.MethodsTwenty guinea-pig (GP) and Sprague-Dawley (SD) rats were pair-matched as donor and recipient randomly.Before transplantation,blood serum collected from other SD rats was inactivated at 45 ℃ in water bath for 30 minutes.Guinea-pig donor livers from experimental group ( n =10 ) were pre-perfused by 0.1％ solution of this blood serum,and donor livers from control group (n =10) were treated by Ringer solution.Then orthotopic liver xenotransplantations were performed by the modified two-cuff technique immediately.Liver morphology changes and survival rate and time of recipients were observed,and histopathological lesions were detected by HE staining,and liver ALT level was evaluated.ResultsThe operation time and anhepatic phases between two groups were not different significantly ( P ＞ 0.05 ).The survival rate of recipients from experimental group was higher,and its survival time was longer than that of control group significantly (P ＜ 0.01 ).The liver histological changes such as thrombosis and interstitial bleeding in experimental group was less severe than that in control group (P ＜0.01 ).The level of ALT in blood serum of rats from experimental group were lower than that from control group significantly ( P ＜ 0.05).ConclusionsThe results suggested that blocking the donor graft with recipient blood serum inhibits HAR during liver xenotransplantation.

Objective To investigate the mechanism of hypedipidemia on pancreas of rats by comparative proteomic analysis.Methods Ten male SD rats were randomly divided into two groups,the experimental group Was fed with high lipid forage and the control group Was fed with normal food.Pancreatic samples from the two groups were harvested six weeks later.Differential protein analysis Was performed using differential in-gel electrophoresis(DIGE),and characterizing the protein biomarkers using tandem mass spectrometry.Western blot Was used to confirm the expression of significantly changed proteins.Results Compared to the normal pancreas tissue,a total of 3 protein spot-features were found to be significantly increased and 11 significantly decreased in pancreatic samples with hyperlipidemia.Significantly increased proteins in hyperlipidemia pancreatic samples were arginaseⅡ,ribonuclease inhibitor and glyeine amidinotransferase,which increased by 2.19,1.82 and 1.12 fold,respectively.Significantly decreased proteins in hyperlipidemia group were tyrosyl-tRNA synthetase,alpha-amylase,triacylglycerol lipase,DJ-1protein,Cu,Zn superoxide dismutase,which dicreased by 2.48,2.37,1.85,1.73 and 1.65 folds,respectively.Western blot analysis revealed increased arginase Ⅱ levels and decreased alpha-amylase in pancreatic samples with hyperlipidemia.Conclusions Pancreas wag possibly injured by hyperlipidemia via increase of arginase Ⅱ.Decreased amylase and lipase may be the protection mechanism of pancreas.

Objective To investigate the occurrence of apoptosis and its relationship with endocrine hormones altemtions in rats with acute obstructive pancreatitis(AOP). Methods The model of AOP wag establisbed by ligation of pancreaticobiliary duct.8,12 hrs after operation,the serum insulin,glucagons and amvlase were determined;pancreatic tissues were harvested and apoptotic rate wag evaluated by TUNEL and flow cytometry(Annexin V-FITC/PI assay).Results 8 and 12 hrs after AOP induction,serum amylase levels wefe(1198±687)U/L and(1698±1103)U/L respectively;serum insulin levels were(8.1±5.8)ng/ml and (12.7 ±6.9)ng/ml respectively;sertlm glucagon levels were(6.8±4.6)ng/ml and(7.3±2.9)ng/ml respectively;all these parameters were significantly high than(404±222)U/L,(5.6±2.7)ng/ml and(2.6±2.1)ng/ml in the sham operation group(P<0.05).AnnemnV FITC/PI assay confirmed apoptosis occurred both in exocrine acinus cells and endocrine panclreas islet;and the apoptotic rate wag(20.5±11.2)%and (15.5±8.9)%at 8 and 12 hrs after AOP induction,which wag significantly high than(4.2±1.6)%in the sham operation group(P<0.05).Conclusions Cell apoptosis occurred in both acinar and islet in the model of AOP,and this may be the pathophysiological basis of endocnne hormones alterations in the model of AOP.

BACKGROUND: In many studies, rats were commonly used as models of retrorsine-induced hepatic injury. Some reports have confirmed that retrorsine cannot inhibit proliferation of mouse hepatic cells. Other reports have shown that retrorsine has inhibitory effects on proliferation of mouse hepatic cells. OBJECTIVE: To study the liver regeneration after hepatic injury by creating mouse models treated with partial hepatectomy combination with retrorsine. METHODS: A total of 40 C57BL/6J mice were equally and randomly assigned to 2 groups. In the partial hepatectomy combined with retrorsine group, intraperitoneal injection of retrorsine 70 mg/kg was conducted, twice, within an interval of 2 weeks. Four weeks later, 2/3 hepatectomy was performed. In the partial hepatectomy group, intraperitoneal injection of saline 70 mg/kg was performed, twice, with an interval of 2 weeks. Four weeks later, 2/3 hepatectomy was performed. At 14 days after partial hepatectomy, the restoration of the livers was observed. The liver cell injury was observed at 3, 7 days with hematoxylin-eosin staining. The hepatocyte proliferation was observed at 3 days with BrdU staining. Oval cell proliferation was observed at 3, 7and 14 days with CK19 and C-kit antibody immunohistochemistry.RESULTS AND CONCLUSION: In the partial hepatectomy group, the damaged liver nearly restored to normal at 14 days after partial hepatectomy, and the result was contrary to partial hepatectomy combined with retrorsine group. Hematoxylin-eosin staining demonstrated that significant degeneration changes in hepatic cells in the partial hepatectomy combined with retrorsine group. BrdU staining showed that hepatocyte proliferation at day 3 was significantly determined in the partial hepatectomy group, but few in the partial hepatectomy combined with retrorsine group. CK19 and C-kit immunohistochemistry demonstrated that visible oval cell proliferation was seen in mice of partial hepatectomy combined with retrorsine group. First of all, hepatic oval cells appeared in portal area and differentiated into hepatic cells and bile duct cells, and then grew into the hepatic lobule gradually. These indicated that retrorsine can obviously inhibit hepatocyte regeneration after liver injury in mice. The model of mice treated with retrorsine and partial hepatectomy could induce oval cell proliferation.
