Objective To explore the relationship between big-five personality,and public mood of volunteers,and to find out the moderator effect of justice sensitivity.Methods A total of 1 022 volunteers were investigated.The Big-Five Inventory (BFI),Public Mood Scale (PMS),Justice Sensitivity Inventory (JSI) were applied to all subjects.Results The average score was (19.77±4.49) for extraversion,(26.69± 4.13) for agreeableness,(23.33±5.37) for conscientiousness,(12.49±4.91) for neuroticism,(24.95±5.44)for openness,(8.78±3.23) for positive public mood,(3.46±3.06) for negative public mood and correlated with (26.85± 10.55) for observer sensitivity.The extraversion,agreeableness,conscientiousness and openness were correlated with positive public mood(β=0.31,P＜0.01;β=0.25,P＜0.01;β=0.29,P＜0.01;β=0.26,P＜0.0 1),and negatively correlated with public mood (β=-0.14,P＜0.01;β=-0.29,P＜0.01;β=-0.20,P＜0.01;β=-0.08,P＜0.01).Neuroticism was negatively correlated with positive public mood (β=-0.27,P＜0.01),and positively correlated with negative public mood (β=0.31,P＜0.01).The interaction effect of agreeableness and observer sensitivity negatively correlated with positive public mood,negative public mood (β=-0.09,P＜0.01;β=-0.07,P＜0.05).The interaction effect of neuroticism and observer sensitivity was positively correlated with positive public mood (β=0.08,P＜0.01).Conclusion Observer sensitivity plays a regulative role between big-five personality and mental health,and can slow the negative impact of low agreeableness to positive public mood,strengthen the impact of low agreeableness to negative public mood,and slow the negative impact of high neuroticism to positive public mood.

Objective To evaluate the therapeutic results of percutaneous transhepatic stent angioplasty in patients with portal vein stenosis following liver transplantation.Methods From 2005 to 2013,38 patients developed portal vein stenosis following liver transplantation.Percutaneous transhepatic angioplasty of the portal vein stenosis was performed on these patients.The results were monitored by clinical follow-up and imaging studies.Results Percutaneous transhepatic angioplasty was successful in these patients.Self-expanding metallic stents (n=7),balloon-expandable coronary stent (n=29),and membranous stent (n=1) were used.The follow-up period ranged from 3 to 90 months.Portal venous patency was maintained in 34 patients (one patient died due to multi organ failure,1 patient accepted a third liver transplantation because of biliary tract complication,and 1 patient received a repeat placement of a membranous tent because the portal vein stent was blocked by a tumor thrombus,and 1 patient developed stent restenosis).There was 1 patient who developed hemorrhage in the early postoperative period (2.63％).A diagnosis of hepatic artery hemorrhage was made by hepatic artery angiography and the patient was treated by interventional embolization.Conclusion Percutaneous transhepatic stent angioplasty is an efficacious and safe method to treat portal vein stenosis following liver transplantation.

Objective To evaluate the medium and long-term therapeutic results of percutaneous transhepatic angioplasty for portal vein stenosis (PSV) following pediatric liver transplantation.Methods From Jan.2008 to Dec.2012,5 cases with PVS after pediatric liver transplantation received percutaneous transhepatic angioplasty.There were 3 male and 2 female cases ranging from 7 months to 8 year-old with the median age of 2 years and 10 months.The protopathy included 1 Carolis disease and 4 congenital biliary atresia.The therapeutic results were monitored by clinical follow-up and imaging examination.The clinical data,imaging examination and therapeutic results were analyzed.Results All interventions were performed successfully,and the treatment efficacy was 100％.One patient was diagnosed with earl-onset PVS at 0.5 month after liver transplantation.Four patients were diagnosed with late-onset PVS at 3-30 months after liver transplantation.The prestenotic portal venous average diameter was (2.3 ± 0.6) mm (1.2-3.0 mm),the degrees of stenosis were 70％-95％.The poststenotic portal venous average diameter was (9 ± 1) mm (8-10 mm) (t =32.560,P ＜ 0.05).The prestenotic portal venous average pressure gradient was (11.0 ± 3.2) mmHg (8-16 mmHg),and the poststenotic portal venous pressure gradient was(2.2 ± 1.5) mmHg(0-4.0 mmHg) (t =8.242,P ＜ 0.05).Postoperative follow-up was 10-66 months,the portal veins of all cases were patent,and patency rate was 100％.Conclusions Percutaneous transhepatic stent angioplasty is an effective and safe method for treatment of PVS following liver transplantation.Its medium and long-term patency rates are high.

Objective To investigate the expression profiles of microRNA in early esophageal squamous cancer and normal esophageal tissues and verify the significantly different expression miRNAs , further to study the effects on proliferation of EC109. Methods The microarray assay was performed to analyze miRNA expression profiles in three pairs of early esophageal squamous cancer and the corresponding normal esophageal tissues. Quantitative real-time polymerase chain reaction (qRT-PCR) was used in another 38 pairs samples to further verify the differentially expressed miRNAs . Three verified miRNAs ( miR-29a, miR-221 and miR-222) mimics were transfected into EC109 respectively and CCK8 method was used to study the effect of cell proliferation in each miRNA. Results Microarray technique selected 53 miRNAs that differentially expressed in early esophageal squamous cancer and normal esophageal tissues , 32 miRNAs were up-regulated and 21 miRNAs were down-regulated. qRT-PCR verified that miR-29a was significantly down-regulated (P < 0.05) and miR-221, miR-222 were significantly up-regulated (P < 0.05) in early esophageal squamous cancer tissue. Over-expression of miR-29a could significantly inhibit the proliferation of EC109 (P < 0.05) whereas over-expression of miR-221 or miR-222 could both significantly promote the proliferation of EC109 (P < 0.05). Conclusion There was significant difference of miRNAs expression between early esophageal squamous cancer and normal esophageal tissues, and the differentially expressed miRNAs could be used as new biomarkers for early diagnosis of esophageal squamous cancer.

Objective To evaluate the therapeutic effectiveness of percutaneous endovascular treatment of hepatic venous outflow obstruction (HVOO)after pediatric liver transplantation(LT).Methods From January 2008 to January 2013,10 children with obstruction of hepatic vein (HV) or inferior vena cava (IVC) anastomosis underwent percutaneous transluminal angioplasty (PTA) with balloon dilation or stent placement.The hepatic venous outflow obstruction occurred 10-455 days (median,125 days) after pediatric liver transplantation.According to the time of obstruction,the obstruction was divide into early onset (＜1 month) and late onset(＞1 month).The effectiveness of PTA was analyzed.Results Twenty-one procedures were performed.One treatment was ineffective,and technical and initial clinical success ratio was 95.2％ (20/21) and 70.0％ (7/10),respectively.In 3 cases with early onset after LT,operation was performed after unsuccessful PTA in 1 case.One patient who developed recurrent stenosis was treated with PTAS.The other patient died of acute rejection.Late onset after LT was found in 7 cases,who were treated with PTA or stent successfully.Conclusions In cases of venous outflow obstruction resulting from HV and/or IVC lesions after pediatric liver transplantation,percutaneous endovascular treatment with balloon dilation or stent placement is a safe and effective alternative treatment that results in midterm and long-term patency.Early-onset or hepatic veins combined with superior vena cava obstruction should be implanted with stents as early as possible.Late-onset or hepatic veins obstruction alone can be get better results with Balloon Dilatation.

AIM:To investigate the effects of resveratrol ( Res) on the proliferation of ARPE-19 cells and to ex-plore the possible mechanisms.METHODS:After ARPE-19 cells were treated with Res at concentrations of 0, 50, 100, 150, 200 and 300 μmol/L for 24 h, 48 h and 72 h, the effects of Res on the proliferation of the cells were tested by CCK-8 assay.The ARPE-19 cells were treated with Res at concentrations of 0, 100, 150 and 200 μmol/L for 48 h.The effects of Res on the cell cycle and apoptosis were detected by flow cytometry with Annexin V-FITC/PI staining.The protein expression of proliferating cell nuclear antigen (PCNA) was detected by immunofluorescent assay.The mRNA expression of PCNA, P21 and P27 was determined by real-time PCR.RESULTS:The results of CCK-8 assay showed that Res inhibited the prolifera-tion of ARPE-19 cells in a time-and dose-dependent manner.The treatment with Res for 48 h resulted in an arrest of cell cycle at S phase without increasing cell apoptosis.Res inhibited the protein expression of PCNA in ARPE-19 cells.The re-sults of real-time PCR showed that Res increased the mRNA expression of P21 and P27, and decreased the mRNA expres-sion of PCNA.CONCLUSION: Res inhibits the proliferation of ARPE-19 cells and induces the cell cycle arrest at S phase.The mechanism may be related to up-regulation of P21 and P27, and down-regulation of PCNA.
